History and Development of the Company

Willis Group Holdings is the ultimate holding company for the Group. We trace our history to 1828 and are one of the largest insurance brokers in the world.

Willis Group Holdings was incorporated in Ireland on September 24, 2009 to facilitate the change of the place of incorporation of the parent company of the Group from Bermuda to Ireland (the ‘Redomicile’). At the Effective Time, the common shares of Willis-Bermuda were canceled, the Willis-Bermuda common shareholders received, on a one-for-one basis, new ordinary shares of Willis Group Holdings, and Willis Group Holdings became the ultimate parent company for the Group.

For administrative convenience, we utilize the offices of a subsidiary company as our principal executive offices. The address is:

Willis Group Holdings Public Limited Company

For several years, we have focused on our core retail and specialist broking operations. In 2008, we acquired HRH, at the time the eighth largest insurance and risk management intermediary in the United States. The acquisition almost doubled our North America revenues and created critical mass in key markets including California, Florida, Texas, Illinois, New York, Boston, New Jersey and Philadelphia. In addition, we have made a number of smaller acquisitions around the world and increased our ownership in several of our associates and existing subsidiaries, which were not wholly-owned, where doing so strengthened our retail network and our specialty businesses.

General

We provide a broad range of insurance brokerage, reinsurance and risk management consulting services to our clients worldwide. We have significant market positions in the United States, in the United Kingdom and, directly and through our associates, in many other countries. We are a recognized leader in providing specialized risk management advisory and other services on a global basis to clients in various industries including aerospace, marine, construction and energy.

In our capacity as an advisor and insurance broker, we act as an intermediary between our clients and insurance carriers by advising our clients on their risk management requirements, helping clients determine the best means of managing risk, and negotiating and placing insurance risk with insurance carriers through our global distribution network.

We assist clients in the assessment of their risks, advise on the best ways of transferring suitable risk to the global insurance and reinsurance markets and then execute the transactions at the most appropriate available price, terms and conditions for our clients. Our global distribution network enables us to place the risk in the most appropriate insurance or reinsurance market worldwide.

We also offer clients a broad range of services to help them to identify and control their risks. These

services range from strategic risk consulting (including providing actuarial analyses), to a variety of due diligence services, to the provision of practical on-site risk control services (such as health and safety or property loss control consulting) as well as analytical and advisory services (such as hazard modeling and reinsurance optimization studies). We assist clients in planning how to manage incidents or crises when they occur. These services include contingency planning, security audits and product tampering plans. We are not an insurance company and therefore we do not underwrite insurable risks for our own account.

We and our associates serve a diverse base of clients including major multinational and middle-market companies in a variety of industries, as well as public institutions and individual clients. Many of our client relationships span decades. We have approximately 20,000 employees around the world (including approximately 3,000 at our associate companies) and a network in excess of 400 offices in some 100 countries.

We believe we are one of only a few insurance brokers in the world possessing the global operating presence, broad product expertise and extensive distribution network necessary to meet effectively the global risk management needs of many of our clients.

Business Strategy

Since 2008, we have launched a series of initiatives to drive profitable growth, including Shaping Our Future, Right Sizing Willis, and Funding for Growth. In 2011, we are realigning our business model to further grow the company and deliver the Willis Cause — our value proposition to clients.

The Willis Cause is our pledge that:

Our Business

Insurance and reinsurance is a global business, and its participants are affected by global trends in capacity and pricing. Accordingly, we operate as one global business which ensures all clients’ interests are handled efficiently and comprehensively, whatever their initial point of

contact. We organize our business into three segments: North America and International, which together comprise our principal retail operations, and Global. In 2010 and 2009, approximately 50 percent of our total revenue was generated from within the US, with no other country contributing in

excess of 20 percent. For information regarding revenues, operating income and total assets per

segment, see Note 26 of the Consolidated Financial Statements contained herein.

Global

Our Global business provides specialist brokerage and consulting services to clients worldwide for the risks arising from specific industrial and commercial activities. In these operations, we have extensive specialized experience handling diverse lines of coverage, including complex insurance programs, and acting as an intermediary between retail brokers and insurers. We increasingly provide consulting services on risk management with the objective of assisting clients to reduce the overall cost of risk. Our Global business serves clients in around 190 countries, primarily from offices in the United Kingdom, although we also serve clients from offices in the United States, Continental Europe and Asia.

The Global business is divided into:

Effective January 1, 2011, we have changed our internal reporting structure; Global Markets International, previously reported within our International segment, is now reported in our Global division.

Global Specialties

Global Specialties has strong global positions in Aerospace, Energy, Marine, Construction, Financial and Executive Risks as well as Financial Solutions.

• Aerospace

We are highly experienced in the provision of insurance and reinsurance brokerage and risk management services to Aerospace clients worldwide, including aircraft manufacturers, air cargo handlers and shippers, airport managers and other general aviation companies. Advisory services provided by Aerospace include claims recovery, contract and leasing risk management, safety services and market information. Aerospace’s clients include approximately one

third of the world’s airlines. The specialist Inspace division is also prominent in supplying the space industry through providing insurance and risk management services to approximately 40 companies.

Our Energy practice provides insurance brokerage services including property damage, offshore construction, liability and control of well and pollution insurance to the energy industry. Our Energy practice clients are worldwide. We are highly experienced in providing insurance brokerage for all aspects of the energy industry including exploration and production, refining and marketing, offshore construction and pipelines.

Our Marine unit provides marine insurance and reinsurance brokerage services, including hull, cargo and general marine liabilities. Marine’s clients include ship owners, ship builders, logistics operators, port authorities, traders and shippers, other insurance intermediaries and insurance companies. Marine insurance brokerage is our oldest line of business dating back to our establishment in 1828.

Our Construction practice provides risk management advice and brokerage services for a wide range of UK and international construction activities. The clients of the Construction practice include contractors, project owners, project managers, project financiers, professional consultants and insurers. We are a broker for many of the leading global construction firms.

Our Financial and Executive Risks unit specializes in broking directors’ and officers’ insurance as well as professional indemnity insurance for corporations and professional firms.

Financial Solutions is a global business unit which incorporates our political risk unit, as well as structured finance and credit teams. It also places structured crime and specialist liability insurance for clients across the broad spectrum of financial institutions as well as specializing in strategic risk assessment and transactional risk transfer solutions.

Willis Re

We are one of the world’s largest intermediaries for reinsurance and have a significant market share in all of the world’s major markets. Our clients are both insurance and reinsurance companies.

We operate this business on a global basis and provide a complete range of transactional capabilities, including, in conjunction with Willis Capital Markets & Advisory, a wide variety of capital markets based products. Our services are underpinned by leading modeling, financial analysis and risk management advice. We bolster and enhance all of these services with the cutting edge knowledge derived from our Willis Research Network, the insurance industry’s largest partnership with global academic research.

London Market Wholesale

This business unit was created on January 1, 2011 and amalgamates Faber & Dumas and Global Markets International.

Faber & Dumas, our wholesale brokerage division, comprises London-based operation, Glencairn, together with our Fine Art, Jewelry and Specie, Special Contingency Risk and Hughes-Gibb units.

Global Markets International works closely with our Global business segment to further develop access for our retail clients to global markets, and provide structuring and placing skills in the relevant areas of property, casualty, terrorism, accident & health, facultative and captives.

Willis Capital Markets & Advisory

Willis Capital Markets & Advisory, with offices in New York and London, provides advice to insurance and reinsurance companies on a broad array of mergers and acquisition transactions as well as capital markets products, including acting as underwriter or agent for primary issuances, operating a secondary insurance-linked securities trading desk and engaging in general capital markets and strategic advisory work.

Retail operations

Our North America and International retail operations provide services to small, medium and

major corporate clients, accessing Global’s specialist expertise when required.

North America

Our North America business provides risk management, insurance brokerage, related risk

services, and employee benefits brokerage and consulting to a wide array of industry and client

segments in the United States and Canada. With around 120 locations, organized into seven geographical regions including Canada, Willis North America locally delivers our global and national resources and specialist expertise through this retail distribution network.

In addition to being organized geographically and by specialty, our North America business focuses on four client segments: global, large national/middle-market, small commercial, and private client, with service, marketing and sales platform support for each segment.

The largest industry practice group in North America is Construction, which specializes in providing risk management, insurance brokerage, and surety bonding services to the construction industry. Willis Construction provided these services to around 25 percent of the Engineering News Record Top 400 contractors (a listing of the largest 400 North American contractors based on revenue). In addition, this practice group has expertise in owner-controlled insurance programs for large projects and insurance for national homebuilders.

Other industry practice groups include Healthcare, serving the professional liability and other insurance and risk management needs of private and not-for-profit health systems, hospitals and physicians groups; Financial Institutions, serving the needs of large banks, insurers and other financial services firms; and Mergers & Acquisitions, providing due diligence, and risk management and insurance brokerage services to private equity and merchant banking firms and their portfolio companies.

Willis Employee Benefits, fully integrated into the North America platform, is our largest product-based practice group and provides health, welfare and human resources consulting, and brokerage services to all of our commercial client segments. This practice group’s value lies in helping clients control employee benefit plan costs, reducing the amount of time human resources professionals spend administering their companies’ benefit plans and educating and training employees on benefit plan issues.

Another industry-leading North America practice group is Willis Executive Risks, a national team of technical professionals who specialize in meeting the directors and officers, employment practices, fiduciary liability insurance risk management, and claims advocacy needs of public and private corporations and organizations. This practice group also has expertise in professional liability, especially internet risks.

The Captive, Actuarial, Programs, Pooling, Personal Lines and Strategic Outcomes (CAPPPS) group has a network of actuaries, certified public accountants, financial analysts and pooled insurance program experts who assist clients in developing and implementing alternative risk management solutions. The program business is a leader in providing national insurance programs to niche industries including ski resorts, auto dealers, recycling, environmental, and specialty workers’ compensation. The group also works with financial institutions to confirm their loans are properly insured and their interests are adequately protected.

International

Our International business comprises our operations in Eastern and Western Europe, the United Kingdom and Ireland, Asia-Pacific, Russia, the Middle East, South Africa and Latin America.

Our offices provide services to businesses locally in over 100 countries around the world, making use of

skills, industry knowledge and expertise available elsewhere in the Group.

The services provided are focused according to the characteristics of each market and vary across offices, but generally include direct risk management and insurance brokerage, specialist and reinsurance brokerage and employee benefits consulting.

We believe the combined total revenues of our International subsidiaries and associates provide an indication of the spread and capability of our International network. The team generated over 30 percent of the Group’s total consolidated commissions and fees in 2010.

As part of our on-going strategy, we look for opportunities to strengthen our International market share through acquisitions and strategic investments. We have acquired a controlling interest in a broad geographic spread of other brokers. A list of significant subsidiaries is included in Exhibit 21.1 to this document.

We have also invested in associate companies; our significant associates at December 31, 2010 were GS & Cie Groupe (‘Gras Savoye’), France (31 percent holding) and Al-Futtaim Willis Co. LLC, Dubai (49 percent holding). In connection with many of our investments we retain the right to increase our ownership over time, typically to a majority or 100 percent ownership position. In addition, in certain instances our co-shareholders have a right, typically based on some price formula of revenues or earnings, to put some or all of their shares to us. On December 17, 2009 as part of a reorganization of the share capital of Gras Savoye our interest in that company reduced from 48 percent to 31 percent. In addition, we have the option to acquire a 100 percent interest in the capital of Gras Savoye in 2015. For further information on the Gras Savoye capital reorganization see ‘Item 8 — Financial Statements and Supplementary Data — Note 13 — Investments in Associates’.

Customers

Our clients operate on a global and local scale in a multitude of businesses and industries throughout the world and generally range in size from major multinational corporations to middle-market companies. Further, many of our client relationships span decades, for instance our relationship with The Tokio Marine and Fire Insurance Company Limited

dates back over 100 years. No one client accounted for more than 10 percent of revenues for fiscal year 2010. Additionally, we place insurance with over 5,000 insurance carriers, none of which individually accounted for more than 10 percent of the total premiums we placed on behalf of our clients in 2010.

Competition

We face competition in all fields in which we operate based on global capability, product breadth, innovation, quality of service and price. According to the Directory of Agents and Brokers published by Business Insurance in July 2010, the 136 largest commercial insurance brokers globally reported brokerage revenues totaling $38 billion in 2009, of which Marsh & McLennan Companies Inc. had approximately 28 percent, Aon Corporation had approximately 20 percent and Willis had approximately 9 percent.

We compete with Marsh & McLennan and Aon as well as with numerous specialist, regional and local firms.

Insurance companies also compete with brokers by directly soliciting insureds without the assistance of an independent broker or agent.

Competition for business is intense in all our business lines and in every insurance market. Competition on premium rates has also exacerbated the pressures caused by a continuing reduction in demand in some classes of business. For example, rather than purchase additional insurance through brokers, many insureds have been retaining a greater proportion of their risk portfolios than previously. Industrial and commercial companies are increasingly relying upon captive insurance companies, self-insurance pools, risk retention

groups, mutual insurance companies and other mechanisms for funding their risks, rather than buying insurance.

Additional competitive pressures arise from the entry of new market participants, such as banks, accounting firms and insurance carriers themselves, offering risk management or transfer services.

In 2005, we, along with Marsh & McLennan and Aon, agreed to implement certain business reforms which included codification of our voluntary termination of contingent commission arrangements with insurers. However, most other special, regional and local insurance brokers continued to accept contingent compensation and did not disclose the compensation received in connection with providing policy placement services to its customers. In February 2010, we entered into the Amended and Restated Assurance of Discontinuance with the Attorney General of the State of New York and the Amended and Restated Stipulation with the

Superintendent of Insurance of the State of New York which ended many of the requirements previously imposed upon us. The new agreement no longer limits the type of compensation we can receive and lowers the compensation disclosure requirements we must make to our clients.

We continue to refuse to accept contingent commissions from carriers in our retail brokerage business. To our knowledge, we are the only insurance broker that takes this stance. We seek to increase revenue through higher commissions and fees that we disclose to our clients, and to generate profitable revenue growth by focusing on the provision of value-added risk advisory services beyond traditional brokerage activities. Although we continue to believe in the success of our strategy, we cannot be certain that such steps will help us to continue to generate profitable organic revenue growth.

Regulation

Our business activities are subject to legal requirements and governmental and quasi-governmental regulatory supervision in virtually all countries in which we operate. Also, such regulations may require individual or company licensing to conduct our business activities. While these requirements may vary from location to location they are generally designed to protect our clients by establishing minimum standards of conduct and practice, particularly regarding the provision of advice and product information as well as financial criteria.

United States

Our activities in connection with insurance brokerage services within the United States are subject to regulation and supervision by state authorities. Although the scope of regulation and form of supervision may vary from jurisdiction to jurisdiction, insurance laws in the United States are often complex and generally grant broad discretion to supervisory authorities in adopting regulations and supervising regulated activities. That supervision generally includes the licensing of insurance brokers and agents and the regulation of the handling and investment of client funds held in

a fiduciary capacity. Our continuing ability to provide insurance brokerage in the jurisdictions in which we currently operate is dependent upon our compliance with the rules and regulations promulgated from time to time by the regulatory authorities in each of these jurisdictions.

European Union

The European Union Insurance Mediation Directive introduced rules to enable insurance and reinsurance intermediaries to operate and provide services within each member state of the EU on a basis consistent with the EU single market and customer protection aims. Each EU member state in which we operate is required to ensure that the insurance and reinsurance intermediaries resident in their country are registered with a statutory body in that country and that each intermediary meets professional requirements in relation to their competence, good repute, professional indemnity cover and financial capacity.

United Kingdom

In the United Kingdom, the statutory body is the Financial Services Authority (‘FSA’). The FSA has prescribed the methods by which our insurance and reinsurance operations are to conduct business, and has a wide range of rule-making, investigatory and enforcement powers aimed at meeting its overall aim of promoting efficient, orderly and fair markets and helping retail consumers achieve a fair deal. The FSA conducts monitoring visits to assess our compliance with regulatory requirements.

Certain of our activities are governed by other regulatory bodies, such as investment and securities licensing authorities. In the United States, Willis Capital Markets & Advisory operates through our wholly-owned subsidiary Willis Securities, Inc., a US-registered broker-dealer and investment advisor, member FINRA/SIPC, primarily in connection with investment banking-related services and advising on alternative risk financing transactions. Willis Capital Markets provides advice on securities or investments

in the EU through our wholly-owned subsidiary Willis Structured Financial Solutions Limited, which is authorized and regulated by the FSA.

Our failure, or that of our employees, to satisfy the regulators that we are in compliance with their requirements or the legal requirements governing our activities, can result in disciplinary action, fines, reputational damage and financial harm.

All companies carrying on similar activities in a given jurisdiction are subject to regulations which are not dissimilar to the requirements for our operations in the United States and United Kingdom. We do not consider that these regulatory requirements adversely affect our competitive position.

See Part I, Item 1A-Risk Factors ‘Legal and Regulatory Risks’ for discussion of how actions by regulatory authorities or changes in legislation and regulation in the jurisdictions in which we operate may have an adverse effect on our business.

Employees

As of December 31, 2010 we had approximately 17,000 employees worldwide of whom approximately 3,400 were employed in the United Kingdom and 6,500 in the United States, with the balance being

employed across the rest of the world. In addition, our associates had approximately 3,000 employees, all of whom were located outside the United Kingdom and the United States.

Risks Relating to our Business and the Insurance Industry

This section describes material risks affecting the Group’s business. These risks could materially affect the Group’s business, its revenues, operating income, net income, net assets, liquidity and capital

resources and ability to achieve its financial targets and, accordingly should be read in conjunction with any forward-looking statements in this Annual Report on Form 10-K.

Competitive Risks

Worldwide economic conditions could have an adverse effect on our business.

Our business and operating results are materially affected by worldwide economic conditions. Current global economic conditions coupled with declining customer and business confidence, increasing energy prices, and other challenges, may have a significant negative impact on the buying behavior of some of our clients as their businesses suffer from these conditions. In particular, financial institutions, construction, aviation, and logistics businesses such as marine cargo are most likely to be affected. Further, the global economic downturn is also negatively affecting some of the international economies that have supported the strong growth in our International operations. Our employee benefits practice may also be adversely affected as businesses continue to downsize during this period of economic turmoil. In addition, a growing number of insolvencies associated with an economic downturn, especially insolvencies in the insurance industry, could adversely affect our brokerage business through the loss of clients or by hampering our ability to place insurance and reinsurance business. While it is difficult to predict consequences of any further deterioration in global economic conditions on our business, any significant reduction or delay by our clients in purchasing insurance or making payment of premiums could have a material adverse impact on our financial condition and results of operations.

The potential for a significant insurer to fail or withdraw from writing certain lines of insurance coverages that we offer our clients could negatively impact overall capacity in the industry, which could then reduce the placement of certain lines and types of insurance and reduce our revenues and profitability. The potential for an insurer to fail could also result in errors and omissions claims by clients.

Since 2008, we have launched certain initiatives, such as the Company’s recently announced 2011 review of operations, the Willis Cause, Right Sizing Willis, Funding for Growth, and Shaping Our Future, to achieve cost-savings or fund our future growth plans. In light of the global economic uncertainty, we continue to vigorously manage our cost base in order to fund further growth initiatives, but we cannot be certain whether we will be able to realize any further benefits from these initiatives or any new initiatives that we may implement.

While we focus on our core retail and specialist broking operations, we do have certain other businesses that are not material to the Group as a whole but which, in any period, could have a material affect on our results of operations.

We do not control the premiums on which our commissions are based, and volatility or declines in premiums may seriously undermine our profitability.

We derive most of our revenues from commissions and fees for brokerage and consulting services. We

do not determine insurance premiums on which our commissions are generally based. Premiums are

Risk factors

cyclical in nature and may vary widely based on market conditions. From the late 1980s through late 2000, insurance premium rates generally declined as a result of a number of factors, including the expanded underwriting capacity of insurance carriers; consolidation of both insurance intermediaries and insurance carriers; and increased competition among insurance carriers. From 2000 to 2003, we benefitted from a ‘hard’ market with premium rates stable or increasing. During 2004, we saw a rapid transition from a hard market, with premium rates stable or increasing, to a ‘soft’ market, with premium rates falling in most markets. The soft market continued to have an adverse impact on our commission revenues and operating margin from 2005 through 2008. Rates continued to decline in most sectors through 2005 and 2006, with the exception of catastrophe-exposed markets. In 2007, the market softened further with decreases in many of the market sectors in which we operated and this continued into 2008 with further premium rate declines across our market sectors. In 2009, the stabilization of rates in the reinsurance market and some specialty markets was offset by the continuing

soft market in other sectors and the adverse impact of the weakened economic environment across the globe. Our North America and UK and Irish retail operations have been particularly impacted by the weakened economic climate and continued soft market throughout both 2009 and 2010 with no material improvement in rates across most sectors. This resulted in declines in 2009 revenues in these operations with only modest improvement in 2010, particularly amongst our smaller clients who have been especially vulnerable to the economic downturn.

In addition, as traditional risk-bearing insurance carriers continue to outsource the production of premium revenue to non-affiliated agents or brokers such as ourselves, those insurance carriers may seek to reduce further their expenses by reducing the commission rates payable to those insurance agents or brokers. The reduction of these commission rates, along with general volatility and/or declines in premiums, may significantly undermine our profitability.

Competition in our industry is intense, and if we are unable to compete effectively, we may suffer lower revenue, reduced operating margins and lose market share which could materially and adversely affect our business.

We face competition in all fields in which we operate, based on global capability, product breadth, innovation, quality of service and price. We compete with Marsh & McLennan and Aon, the two other providers of global risk management services, as well as with numerous specialist, regional and local firms. Competition for business is intense in all our business lines and in every insurance market, and the other two providers of global risk management services have substantially greater market share than we do. Competition on premium rates has also exacerbated the pressures caused by a continuing reduction in demand in some classes of business. For example, rather than purchase additional insurance through brokers, many insureds have been retaining a greater proportion of their risk portfolios than previously. Industrial and commercial companies have been increasingly relying upon their own subsidiary insurance companies, known as captive insurance companies,

self-insurance pools, risk retention groups, mutual insurance companies and other mechanisms for funding their risks, rather than buying insurance. Additional competitive pressures arise from the entry of new market participants, such as banks, accounting firms and insurance carriers themselves, offering risk management or transfer services.

profitable revenue growth by focusing on the provision of value-added risk advisory services beyond traditional brokerage activities. Although we continue to believe in the success of our strategy, we cannot be certain that such steps will help us to continue to generate profitable organic revenue growth. If we are unable to compete effectively against our competitors who are accepting or may accept contingent commissions, we may suffer lower revenue, reduced operating margins and loss of market share which could materially and adversely affect our business.

Dependence on Key Personnel — The loss of our Chairman and Chief Executive Officer or a number of our senior management or a significant number of our brokers could significantly impede our financial plans, growth, marketing and other objectives.

The loss of our Chairman and Chief Executive Officer or a number of our senior management or a significant number of our brokers could significantly impede our financial plans, growth, marketing and other objectives. Our success depends to a substantial extent not only on the ability and experience of our Chairman and Chief Executive Officer, Joseph J. Plumeri and other members of our senior management, but also on the individual brokers and teams that service our clients and maintain client relationships. The insurance and

reinsurance brokerage industry has in the past experienced intense competition for the services of leading individual brokers and brokerage teams, and we have lost key individuals and teams to competitors. We believe that our future success will depend in part on our ability to attract and retain additional highly skilled and qualified personnel and to expand, train and manage our employee base. We may not continue to be successful in doing so because the competition for qualified personnel in our industry is intense.

Legal and Regulatory Risks

Our compliance systems and controls cannot guarantee that we are in compliance with all applicable federal and state or foreign laws and regulations, and actions by regulatory authorities or changes in applicable laws and regulations in the jurisdictions in which we operate may have an adverse effect on our business.

Our activities are subject to extensive regulation under the laws of the United States, the United Kingdom and the European Union and its member states, and the other jurisdictions in which we operate. Indeed, over the last few years, there has been a general increase in focus and developments in these laws and regulations. Compliance with laws

and regulations that are applicable to our operations is complex and may increase our cost of doing business. These laws and regulations include insurance industry regulations, economic and trade sanctions and laws against financial crimes such as money laundering, bribery or other corruption, such as the U.S. Foreign Corrupt Practices Act. In most

jurisdictions, governmental and regulatory authorities have the ability to interpret and amend these laws and regulations and impose penalties for non-compliance, including sanctions, civil remedies, fines, injunctions, revocation of licenses or approvals, suspension of individuals, limitations on business activities or redress to clients.

Given the increased interest expressed by UK and US regulators in the effectiveness of compliance controls relating to financial crime in our market sector in particular, we began a voluntary internal review of our policies and controls four years ago. This review includes analysis and advice from external experts on best practices, review of public regulatory decisions, and discussions with government regulators in the UK and US. In

addition, the U.K. Financial Services Authority is conducting an investigation of some of our compliance systems and controls between 2005 and 2009. While we are fully cooperating with our regulators, we are unable to predict at this time when these matters will be concluded. We do not believe that such matters will result in any material fines or sanctions from UK or US regulators, but there can be no assurance that any resolution will not have an adverse impact on our ability to conduct our business in certain jurisdictions. While we believe that our current systems and controls are adequate and in accordance with all applicable laws and regulations, we cannot assure that such systems and controls will prevent any violations of applicable laws and regulations.

Our business, results of operations, financial condition or liquidity may be materially adversely affected by actual and potential claims, lawsuits, investigations and proceedings.

We are subject to various actual and potential claims, lawsuits, investigations and other proceedings relating principally to alleged errors and omissions in connection with the placement of insurance and reinsurance in the ordinary course of business. Because we often assist our clients with matters, including the placement of insurance coverage and the handling of related claims, involving substantial amounts of money, errors and omissions claims against us may arise which allege our potential liability for all or part of the amounts in question.

Claimants can seek large damage awards and these claims can involve potentially significant defense costs. Such claims, lawsuits and other proceedings could, for example, include allegations of damages for our employees or sub-agents improperly failing to place coverage or notify claims on behalf of clients, to provide insurance carriers with complete and accurate information relating to the risks being insured or to appropriately apply funds that we hold for our clients on a fiduciary basis. Errors and omissions claims, lawsuits and other proceedings arising in the ordinary course of business are covered in part by professional indemnity or other appropriate insurance. The terms of this insurance vary by policy year and self-insured risks have increased significantly in recent years. In respect of

self-insured risks, we have established provisions against these items which we believe to be adequate in the light of current information and legal advice, and we adjust such provisions from time to time according to developments. Our business, results of operations, financial condition and liquidity may be adversely affected if in the future our insurance coverage proves to be inadequate or unavailable or there is an increase in liabilities for which we self-insure. Our ability to obtain professional indemnity insurance in the amounts and with the deductibles we desire in the future may be adversely impacted by general developments in the market for such insurance or our own claims experience.

We are also subject to actual and potential claims, lawsuits, investigations and proceedings outside of errors and omissions claims. The material actual or potential claims, lawsuits and proceedings to which we are currently subject, including but not limited to errors and omissions claims, are: (1) potential claims arising out of various legal proceedings between reinsurers, reinsureds and their reinsurance brokers relating to personal accident excess of loss reinsurance placements for the years 1993 to 1998; and (2) claims relating to the collapse of The Stanford Financial Group, for which we acted as brokers of record on certain lines of insurance.

The ultimate outcome of these matters cannot be ascertained and liabilities in indeterminate amounts may be imposed on us. It is thus possible that future results of operations or cash flows for any particular quarterly or annual period could be materially affected by an unfavorable resolution of these matters. In addition, these matters continue to divert management and personnel resources away from

operating our business. Even if we do not experience significant monetary costs, there may also be adverse publicity associated with these matters that could result in reputational harm to the insurance brokerage industry in general or to us in particular that may adversely affect our business, client or employee relationships.

Interruption to or loss of our information processing capabilities or failure to effectively maintain and upgrade our information processing systems could cause material financial loss, loss of human resources, regulatory actions, reputational harm or legal liability.

Our business depends significantly on effective information systems. Our capacity to service our clients relies on effective storage, retrieval, processing and management of information. Our information systems also rely on the commitment of significant resources to maintain and enhance existing systems and to develop new systems in order to keep pace with continuing changes in information processing technology or evolving industry and regulatory standards. The acquisition of HRH and additional information systems has added

to this exposure. If the information we rely on to run our business were found to be inaccurate or unreliable or if we fail to maintain effective and efficient systems (including through a telecommunications failure, failure to replace or update redundant or obsolete computer applications or software systems or if we experience other disruptions), this could result in material financial loss, regulatory action, reputational harm or legal liability.

Our inability to successfully recover should we experience a disaster or other significant disruption to business continuity could have a material adverse effect on our operations.

Our ability to conduct business may be adversely affected, even in the short-term, by a disruption in the infrastructure that supports our business and the communities where we are located. This may include a disruption caused by restricted physical site access, terrorist activities, disease pandemics, or outages to electrical, communications or other services used by our company, our employees or third parties with whom we conduct business. Although we have certain disaster recovery procedures in place and insurance to protect against

such contingencies, such procedures may not be effective and any insurance or recovery procedures may not continue to be available at reasonable prices and may not address all such losses or compensate us for the possible loss of clients occurring during any period that we are unable to provide services. Our inability to successfully recover should we experience a disaster or other significant disruption to business continuity could have a material adverse effect on our operations.

Improper disclosure of personal data could result in legal liability or harm our reputation.

One of our significant responsibilities is to maintain the security and privacy of our clients’ confidential

and proprietary information and the personal data of their employees. We maintain policies, procedures

and technological safeguards designed to protect the security and privacy of this information in our database. However, we cannot entirely eliminate the risk of improper access to or disclosure of personally identifiable information. Our technology may fail to adequately secure the private information we maintain in our databases and protect it from theft or inadvertent loss. In such circumstances, we may be held liable to our clients, which could result in legal liability or impairment to

our reputation resulting in increased costs or loss of revenue. Further database privacy, identity theft, and related computer and internet issues are matters of growing public concern and are subject to frequently changing rules and regulations. Our failure to adhere to or successfully implement processes in response to changing regulatory requirements in this area could result in legal liability or impairment to our reputation in the marketplace.

Financial Risks

Our outstanding debt could adversely affect our cash flows and financial flexibility.

As of December 31, 2010, we had total consolidated debt outstanding of approximately $2.3 billion and interest expense was $166 million. Although management believes that our cash flows will be more than adequate to service this debt, there may be circumstances in which required payments of principal and/or interest on this debt could adversely affect our cash flows and this level of indebtedness may:

The terms of our current financings also include certain limitations. For example, the agreements relating to the debt arrangements and credit facilities contain numerous operating and financial covenants, including requirements to maintain minimum ratios of consolidated adjusted EBITDA to consolidated fixed charges and maximum levels of consolidated funded indebtedness in relation to consolidated EBITDA, in each case subject to certain adjustments.

A failure to comply with the restrictions under our credit facilities and outstanding notes could result in a default under the financing obligations or could require us to obtain waivers from our lenders for failure to comply with these restrictions. The occurrence of a default that remains uncured or the inability to secure a necessary consent or waiver could cause our obligations with respect to our debt to be accelerated and have a material adverse effect on our business, financial condition or results of operations.

Our pension liabilities may increase which could require us to make additional cash contributions to our pension plans.

We have two principal defined benefit plans: one in the United Kingdom and the other in the United States. Cash contributions of approximately $119 million will be required in 2011 for these pension plans, although we may elect to contribute more. Total cash contributions to these defined benefit

pension plans in 2010 were $118 million. Future estimates are based on certain assumptions, including discount rates, interest rates, fair value of assets and expected return on plan assets. In the UK, we are required to agree a funding strategy for our UK defined benefit plan with the plan’s trustees.

In February 2009, we agreed to make full year contributions to the UK plan of $39 million for 2009 through 2012, excluding amounts in respect of the salary sacrifice scheme. In addition, if certain funding targets were not met at the beginning of any of the following years, 2010 through 2012, a further contribution of $39 million would be required for that year. In 2010, the additional funding requirement was triggered and we expect to make a similar additional contribution in 2011. A similar, additional contribution may also be required for 2012, depending on actual performance against funding targets at the beginning of 2012. We have taken actions to manage our pension liabilities, including closing our UK and US plans to new participants and restricting final pensionable salaries. Future benefit accruals in the US pension plan were also stopped, or frozen, on May 15, 2009.

The determinations of pension expense and pension funding are based on a variety of rules and regulations. Changes in these rules and regulations could impact the calculation of pension plan liabilities and the valuation of pension plan assets. They may also result in higher pension costs, additional financial statement disclosure, and accelerate and increase the need to fully fund our pension plans. Our future required cash contributions to our US and UK defined benefit pension plans may increase based on the funding reform provisions that were enacted into law. Further, a significant decline in the value of investments that fund our pension plan, if not offset

or mitigated by a decline in our liabilities, may significantly differ from or alter the values and actuarial assumptions used to calculate our future pension expense and we could be required to fund our plan with significant amounts of cash. In addition, if the US Pension Benefit Guaranty Corporation requires additional contributions to such plans or if other actuarial assumptions are modified, our future required cash contributions could increase. The need to make these cash contributions may reduce the cash available to meet our other obligations, including the payment obligations under our credit facilities and other long-term debt, or to meet the needs of our business.

In addition to the critical assumptions described above, our plans use certain assumptions about the life expectancy of plan participants and surviving spouses. Periodic revision of those assumptions can materially change the present value of future benefits and therefore the funded status of the plans and the resulting periodic pension expense. Changes in our pension benefit obligations and the related net periodic costs or credits may occur in the future due to any variance of actual results from our assumptions and changes in the number of participating employees. As a result, there can be no assurance that we will not experience future decreases in stockholders equity, net income, cash flow and liquidity or that we will not be required to make additional cash contributions in the future beyond those which have been estimated.

We could incur substantial losses if one of the financial institutions we use in our operations failed.

The deterioration of the global credit and financial markets has created challenging conditions for financial institutions, including depositories. As the fallout from the credit crisis persists, the financial strength of these institutions may continue to decline. We maintain cash balances at various US depository institutions that are significantly in excess of the US Federal Deposit Insurance Corporation insurance

limits. We also maintain cash balances in foreign financial institutions. If one or more of the institutions in which we maintain significant cash balances were to fail, our ability to access these funds might be temporarily or permanently limited, and we could face a material liquidity problem and potentially material financial losses.

A downgrade in the credit ratings of our outstanding debt may adversely affect our borrowing costs and financial flexibility.

A downgrade in our corporate credit rating or the credit ratings of our debt would increase our borrowing costs including those under our credit facilities, and reduce our financial flexibility. In addition, certain downgrades would trigger a step-up in interest rates under the indentures for our

6.2% senior notes due 2017 and our 7.0% senior notes due 2019, which would increase our interest expense. If we need to raise capital in the future, any credit rating downgrade could negatively affect our financing costs or access to financing sources.

We face certain risks associated with the acquisition or disposition of business or reorganization of existing investments.

In pursuing our corporate strategy, we may acquire or dispose of or exit businesses or reorganize existing investments. The success of this strategy is dependent upon our ability to identify appropriate opportunities, negotiate transactions on favorable terms and ultimately complete such transactions. Once we complete acquisitions or reorganizations there can be no assurance that we will realize the anticipated benefits of any transaction, including revenue growth, operational efficiencies or expected synergies. For example, if we fail to recognize some or all of the strategic benefits and synergies

expected from a transaction, goodwill and intangible assets may be impaired in future periods. In addition, we may not be able to integrate acquisitions successfully into our existing business, and we could incur or assume unknown or unanticipated liabilities or contingencies, which may impact our results of operations. If we dispose of or otherwise exit certain businesses, there can be no assurance that we will not incur certain disposition related charges, or that we will be able to reduce overheads related to the divested assets.

We are a holding company and, therefore, may not be able to receive dividends or other distributions in needed amounts from our subsidiaries.

Willis Group Holdings is organized as a holding company that conducts no business of its own. We are dependent upon dividends and other payments from our operating subsidiaries to meet our obligations for paying principal and interest on outstanding debt obligations, for paying dividends to shareholders and for corporate expenses. Legal and regulatory restrictions, foreign exchange controls, as

well as operating requirements of our subsidiaries, may limit our ability to obtain cash from these subsidiaries. In the event our operating subsidiaries are unable to pay dividends and make other payments to Willis Group Holdings, we may not be able to service debt, pay obligations or pay dividends on ordinary shares.

International Risks

Our significant non-US operations, particularly our London market operations, expose us to exchange rate fluctuations and various risks that could impact our business.

A significant portion of our operations is conducted outside the United States. Accordingly, we are subject to legal, economic and market risks

associated with operating in foreign countries, including devaluations and fluctuations in currency exchange rates; imposition of limitations on

conversion of foreign currencies into pounds sterling or dollars or remittance of dividends and other payments by foreign subsidiaries; hyperinflation in certain foreign countries; imposition or increase of investment and other restrictions by foreign governments; and the requirement of complying with a wide variety of foreign laws.

We report our operating results and financial condition in US dollars. Our US operations earn revenue and incur expenses primarily in US dollars. In our London market operations, however, we earn revenue in a number of different currencies, but expenses are almost entirely incurred in pounds sterling. Outside the United States and our London market operations, we predominantly generate revenue and expenses in the local currency. The table gives an approximate analysis of revenues and expenses by currency in 2010.

Revenues

Expenses

Because of devaluations and fluctuations in currency exchange rates or the imposition of limitations on conversion of foreign currencies into US dollars, we are subject to currency translation exposure on the

profits of our operations, in addition to economic exposure. Furthermore, the mismatch between pounds sterling revenues and expenses, together with any net sterling balance sheet position we hold in our US dollar denominated London market operations, creates an exchange exposure.

For example, as the pound sterling strengthens, the US dollars required to be translated into pounds sterling to cover the net sterling expenses increase, which then causes our results to be negatively impacted. Our results may also be adversely impacted if we are holding a net sterling position in our US dollar denominated London market operations: if the pound sterling weakens any net sterling asset we are holding will be less valuable when translated into US dollars. Given these facts, the strength of the pound sterling relative to the US dollar has in the past had a material negative impact on our reported results. This risk could have a material adverse effect on our business financial condition, cash flow and results of operations in the future.

Where possible, we hedge part of our operating exposure to exchange rate movements, but such mitigating attempts may not be successful.

In conducting our businesses around the world, we are subject to political, economic, legal, market, nationalization, operational and other risks that are inherent in operating in many countries.

In conducting our businesses and maintaining and supporting our global operations, we are subject to political, economic, legal, market, nationalization, operational and other risks. Our businesses and operations are increasingly expanding into new regions throughout the world, including emerging markets, and we expect this trend to continue. The possible effects of economic and financial disruptions throughout the world could have an adverse impact on our businesses. These risks include:

Legislative and regulatory action could materially and adversely affect us and our effective tax rate may increase.

There is uncertainty regarding the tax policies of the jurisdictions where we operate (which include the potential legislative actions described below), and our effective tax rate may increase and any such increase may be material. Additionally, the tax laws of Ireland and other jurisdictions could change in the future, and such changes could cause a material change in our effective tax rate. For example, legislative action may be taken by the US Congress which, if ultimately enacted, could override tax treaties upon which we rely or could broaden the circumstances under which we would be considered

a US resident, each of which could materially and adversely affect our effective tax rate and cash tax position. We cannot predict the outcome of any specific legislative proposals. However, if proposals were enacted that had the effect of limiting our ability to take advantage of tax treaties between Ireland and other jurisdictions (including the US), we could be subjected to increased taxation. In addition, any future amendments to the current income tax treaties between Ireland and other jurisdictions could subject us to increased taxation.

Irish law differs from the laws in effect in the United States and may afford less protection to holders of our securities.

It may not be possible to enforce court judgments obtained in the United States against us in Ireland based on the civil liability provisions of the US federal or state securities laws. In addition, there is some uncertainty as to whether the courts of Ireland would recognize or enforce judgments of US courts obtained against us or our directors or officers based on the civil liabilities provisions of the US federal or state securities laws or hear actions against us or those persons based on those laws. We have been advised that the United States currently does not have a treaty with Ireland providing for the reciprocal recognition and enforcement of judgments in civil and commercial matters. Therefore, a final judgment for the payment of money rendered by any US federal or state court based on civil liability, whether or not based solely on US federal or state securities laws, would not be directly enforceable in Ireland. While not directly enforceable, it is possible for a final judgment for the payment of money rendered by any US federal or state court based on civil liability to be enforced in Ireland through common law rules. However, this

process is subject to numerous established principles and would involve the commencement of a new set of proceedings in Ireland to enforce the judgment.

As an Irish company, Willis Group Holdings is governed by the Irish Companies Acts, which differ in some material respects from laws generally applicable to US corporations and shareholders, including, among others, differences relating to interested director and officer transactions and shareholder lawsuits. Likewise, the duties of directors and officers of an Irish company generally are owed to the company only. Shareholders of Irish companies generally do not have a personal right of action against directors or officers of the company and may exercise such rights of action on behalf of the Company only in limited circumstances. Accordingly, holders of Willis Group Holdings securities may have more difficulty protecting their interests than would holders of securities of a corporation incorporated in a jurisdiction of the United States.

Our non-core operations pose certain underwriting, advisory or reputational risks.

We provide a broad range of brokerage, reinsurance and risk management consulting services to our clients worldwide. We also engage in certain non-core operations. For example, our Willis Capital Markets & Advisory business provides advice to insurance and reinsurance companies on a broad array of mergers and acquisition transactions as well

as capital markets products, including acting as underwriter or agent for primary issuances, operating a secondary insurance-linked securities trading desk and engaging in general capital markets and strategic advisory work. These operations may pose certain underwriting, advisory or reputational risks to our core business.

The Company had no unresolved comments from the SEC’s staff.

Properties

We own and lease a number of properties for use as offices throughout the world and believe that our properties are generally suitable and adequate for the purposes for which they are used. The principal properties are located in the United Kingdom and the United States. Willis maintains over 4.1 million square feet of space worldwide.

London

In London we occupy a prime site comprising 491,000 square feet spread over a 28 story tower and adjoining 10 story building. We have a 25-year lease on this property which expires June 2032 and we sub-let the 10-story adjoining building.

North America

In North America, outside of New York and Chicago, we lease approximately 2.0 million square feet over 130 locations.

New York

In New York, we occupy 205,000 square feet of office space at One World Financial Center under a 20 year lease, expiring September 2026.

Chicago

In Chicago, we occupy 140,000 square feet at the Willis Tower (formerly the Sears Tower), under a lease expiring February 2025.

Nashville

In 2010 we renegotiated our lease and began a major restack of our operations facility in Nashville. The first stage was completed in December 2010 and the remainder will be complete by May 2011. We reduced our square footage from 327,000 square feet to 160,000 square feet eliminating sublet space.

Rest of World

Outside of North America and London we lease approximately 1.3 million square feet of office space in over 190 locations.

There are no governmental laws, decrees or regulations in Ireland which will restrict the remittance of dividends or other payments to non-resident holders of the Company’s shares.

In circumstances where one of Ireland’s many exemptions from dividend withholding tax (‘DWT’) does not apply, dividends paid by the Company will be subject to Irish DWT (currently 20 percent). Residents of the US should be exempted from Irish

DWT provided relevant documentation supporting the exemption has been put in place. While the US-Ireland Double Tax Treaty contains provisions reducing the rate of Irish DWT in prescribed circumstances, it should generally be unnecessary for US residents to rely on the provisions of this treaty due to the wide scope of exemptions from DWT available under Irish domestic law. Irish income tax may also arise in respect of dividends paid by the Company. However, US residents entitled to an exemption from Irish DWT generally have no Irish income tax liability on dividends. An exception to this position applies where a shareholder holds shares in the Company through a branch or agency in Ireland through which a trade is carried on.

With respect to non-corporate US shareholders, certain dividends received before January 1, 2011 from a qualified foreign corporation may be subject to reduced rates of taxation. A foreign corporation is treated as a qualified foreign corporation with respect to dividends received from that corporation on shares that are readily tradable on an established securities market in the United States, such as our shares. Non-corporate US shareholders that do not

meet a minimum holding period requirement for our shares during which they are not protected from the risk of loss or that elect to treat the dividend income as ‘investment income’ pursuant to section 163(d)(4) of the Code will not be eligible for the reduced rates of taxation regardless of our status as a qualified foreign corporation. In addition, the rate reduction will not apply to dividends if the

recipient of a dividend is obligated to make related payments with respect to positions in substantially similar or related property. This disallowance applies even if the minimum holding period has been met. US shareholders should consult their own tax advisors regarding the application of these rules given their particular circumstances.

Unregistered Sales of Equity Securities and Use Of Proceeds

During the quarter ended December 31, 2010, no shares were issued by the Company without registration under the Securities Act of 1933, as amended.

Purchases of Equity Securities by the Issuer And Affiliated Purchasers

Under a share buyback program approved by the Board of Directors, the Company may purchase up to one billion shares, from time to time in the open market. The authorization to make purchases of Company shares on the open market will expire on June 30, 2011 unless varied, revoked or renewed by a resolution of the shareholders in accordance with Irish law. The Company may also purchase shares through negotiated trades with persons who are not affiliates of the Company. These negotiated trade purchases are effected by way of share redemption and do not require Shareholder approval. The authorization in

respect of open market purchases provides that the cost of the acquisition of the Company’s shares (whether by redemption or on the open market) may not exceed $925 million. During the year ended December 31, 2010, there were no shares repurchased.

Business discussion

This discussion includes references to non-GAAP financial measures as defined in Regulation G of the rules of the Securities and Exchange Commission (‘SEC’). We present such non-GAAP financial measures, as we believe such information is of interest to the investment community because it provides additional meaningful methods of evaluating certain aspects of the Company’s operating performance from period to period on a basis that may not be otherwise apparent on a GAAP basis. Organic revenue growth and organic growth in commissions and fees exclude the impact of acquisitions and disposals, year over year movements in foreign currency translation, legacy contingent commissions assumed as part of the HRH acquisition, and investment and other income from reported revenues. We believe organic revenue growth and organic growth in commissions and fees provide measures that the investment community may find helpful in assessing the performance of

operations that were part of our operations in both the current and prior periods, and provide measures against which our businesses may be assessed in the future. These financial measures should be viewed in addition to, not in lieu of, the consolidated financial statements for the year ended December 31, 2010.

This discussion includes forward-looking statements, including under the headings ‘Business Overview and Market Outlook’, ‘Executive Summary’, ‘Operating Results — Group’, ‘Operating Results — Segment Information’ and ‘Liquidity and Capital Resources’. Please see ‘Forward-Looking Statements’ for certain cautionary information regarding forward-looking statements and a list of factors that could cause actual results to differ materially from those predicted in the forward-looking statements.

BUSINESS OVERVIEW AND MARKET OUTLOOK

We provide a broad range of insurance broking, risk management and consulting services to our clients worldwide. Our core specialty businesses include Aerospace; Energy; Marine; Construction; Financial and Executive Risks; Fine Art, Jewelry and Specie; Special Contingency Risks; and Reinsurance. Our retail operations provide services to small, medium and major corporations and the employee benefits practice, our largest product-based practice group, provides health, welfare and human resources consulting and brokerage services.

In our capacity as advisor and insurance broker, we act as an intermediary between our clients and insurance carriers by advising our clients on their risk management requirements, helping clients determine the best means of managing risk, and negotiating and placing insurance risk with insurance carriers through our global distribution network.

We derive most of our revenues from commissions and fees for brokerage and consulting services and do not determine the insurance premiums on which our commissions are generally based. Fluctuations in these premiums charged by the insurance carriers

have a direct and potentially material impact on our results of operations. Commission levels generally follow the same trend as premium levels as they are derived from a percentage of the premiums paid by the insureds. Due to the cyclical nature of the insurance market and the impact of other market conditions on insurance premiums, they may vary widely between accounting periods. Reductions in premium rates, leading to downward pressure on commission revenues (a ‘soft’ market), can have a potentially material adverse impact on our commission revenues and operating margin.

A ‘hard’ market occurs when premium uplifting factors, including a greater than anticipated loss experience or capital shortages, more than offset any downward pressures on premiums. This usually has a favorable impact on our commission revenues and operating margin.

From 2000 through 2003 we benefited from a hard market with premium rates stable or increasing. During 2004, we saw a rapid transition from a hard market to a soft market, with premium rates falling in most markets. Rates continued to decline in most sectors through 2005 and 2006, with the exception

of catastrophe-exposed markets. In 2007, the market softened further with decreases in many of the market sectors in which we operated and this continued into 2008 with further premium rate declines across our markets. The soft market had an adverse impact on our commission revenues and operating margin from 2005 through 2008.

In 2009, modest stabilization of rates in the reinsurance market and some specialty markets was offset by the continuing soft market in other sectors and the adverse impact of the weakened economic environment across the globe.

In 2010, the soft market continued across many sectors including the reinsurance market.

Our North America and UK and Irish retail operations have been particularly impacted by the weakened economic climate and continued soft market throughout both 2009 and 2010 with no material improvement in rates across most sectors.

This resulted in declines in 2009 revenues in these operations with only modest improvement in 2010, particularly amongst our smaller clients who have been especially vulnerable to the economic downturn.

In 2011, our main priorities will include:

EXECUTIVE SUMMARY

Overview

Despite the difficult market conditions during the year, we reported total revenue growth of 2 percent in 2010 mainly reflecting 4 percent organic growth in commissions and fees partly offset by a negative 1 percent impact from foreign currency translation.

Organic revenue growth was driven by our Global and International operations which both reported 6 percent organic growth, whilst revenues in our North America operations were broadly in line with 2009, as this segment continued to be adversely

impacted by the soft market and difficult economic conditions.

Operating margin was 23 percent in 2010, compared with 21 percent in 2009. The year on year improvement mainly reflected the benefit of organic growth in commissions and fees, continuing disciplined management of costs and a small favorable effect from foreign currency movements, partly offset by increased incentive costs.

Results from continuing operations: 2010 compared with 2009

Net income from continuing operations in 2010 was $455 million, or $2.66 per diluted share, compared with $436 million, or $2.58 per diluted share, in 2009.

Total revenues from continuing operations at $3,339 million for 2010 were $76 million, or 2 percent, higher than in 2009, reflecting organic commissions and fees growth of 4 percent, partly offset by an adverse impact from foreign currency translation, a $16 million decrease attributable to the year over year reduction in contingent

commissions assumed as part of the HRH acquisition and a $14 million decrease in investment and other income.

Organic commissions and fees growth of 4 percent comprised 6 percent net new business growth (which constitutes the revenue growth from business won over the course of the year net of the revenue from existing business lost) and a 2 percent negative impact from declining premium rates and other market factors.

Operating margin at 23 percent was 2 percentage points higher than in 2009 with the increase mainly reflecting:

partly offset by

Interest expense in 2010 was $166 million, $8 million lower than in 2009, as the benefit of the interest expense savings arising from the year over year reduction in average term loan and revolving credit facility balances was partly offset by the effect of the higher coupon payable on the $500 million of 12.875% senior unsecured notes issued in March 2009.

Income tax expense for 2010 was $140 million compared with $96 million in 2009. Both years benefited from a release of provisions for uncertain tax positions and 2009 additionally benefited from a $27 million tax credit following a change to UK tax law.

Earnings from associates were $23 million in 2010 compared with $33 million in 2009 with the decrease primarily reflecting our reduced ownership of Gras Savoye.

Results from continuing operations: 2009 compared with 2008

Net income from continuing operations in 2009 was $436 million, or $2.58 per diluted share, compared with $302 million, or $2.04 per diluted share, in 2008. This increase included organic growth in commissions and fees, a reduction in costs associated with our 2008 expense review from $0.45 per diluted share in 2008 to $0.11 per diluted share for severance costs in 2009 and a one-time tax release in 2009 relating to a change in UK tax law in 2009 equivalent to $0.16 per diluted share.

Total revenues from continuing operations at $3,263 million for 2009 were $436 million, or 15 percent, higher than in 2008. Organic revenue growth of 2 percent and a 19 percent benefit from net acquisitions and disposals in 2009, driven by the fourth quarter 2008 acquisition of HRH, were partly offset by a negative 4 percent impact from foreign currency translation and a $31 million decrease in investment income compared to 2008.

Organic revenue growth of 2 percent comprised 5 percent net new business growth (which

constitutes the revenue growth from business won over the course of the year net of the revenue from existing business lost) and a 3 percent negative impact from declining premium rates and other market factors.

Operating margin at 21 percent was 3 percentage points higher than in 2008 with the increase mainly reflecting:

Willis aims to be the broker and risk adviser of choice globally by aligning our business model to the needs of each client segment and maintaining a focus on growth: this is our value proposition which we call the ‘Willis Cause’.

We expect 2011 salaries and benefits expense to include an increase of approximately $100 million compared with 2010 as a result of the following:

We estimate that of those items noted above, approximately $20 million to $25 million will continue through to 2012 as incremental expense: reflecting a further but significantly lower increase in the amortization of cash retention awards in 2012

compared with 2011, and the full year impact of the 2011 annual salary review.

In addition to these costs, we will continue to invest in technology, advanced analytics, product innovation, and industry talent and expertise to support the growth strategy and continued execution of the Willis Cause through 2011 and beyond.

In order to fund the higher anticipated salaries and benefits expense and these investments, we are undertaking a review of all our businesses to better align our resources with our growth strategies. We expect to complete this review in the first quarter of 2011.

In connection with this review, we anticipate that we will incur pre-tax charges of approximately $110 million to $130 million, primarily recorded in the first quarter of 2011. We also anticipate that the operational review will result in cost savings of approximately $65 million to $80 million in 2011, reaching annualized savings of approximately $90 million to $100 million in 2012.

Outlook

As a result of the 2011 operational review and the continued investment in our business model, we expect to deliver:

The statements under ‘2011 Operational Review’ and ‘Outlook’ constitute forward-looking statements.

Please see ‘Forward-Looking Statements’ for certain cautionary information regarding forward-looking statements and a list of factors that could cause actual results to differ materially from those predicted in the forward-looking statements.

Venezuela currency devaluation

With effect from January 1, 2010 the Venezuelan economy was designated as hyper-inflationary. The Venezuelan government also devalued the Bolivar Fuerte in January 2010. As a result of these actions,

we recorded a $12 million charge in other expenses in 2010 to reflect the re-measurement of our net assets denominated in Venezuelan Bolivar Fuerte at January 1, 2010.

Acquisitions

During 2010, we acquired:

Cash and financing

Cash at December 31, 2010 was $316 million, $95 million higher than at December 31, 2009. This increase in cash was partly attributable to additional cash balances being held in our main UK regulated company.

Net cash generated from operating activities in 2010 was $489 million compared with $419 million in 2009.

Net cash generated from operating activities in 2010 of $489 million was used to fund debt repayments of $209 million; dividends to stockholders of $176 million; and fixed asset additions of $83 million.

In August 2010, we entered into a new revolving credit facility agreement under which a further $200 million is available. This facility is in addition to the remaining availability under our previously existing $300 million revolving credit facility.

In addition, in June 2010, we entered into an additional facility solely for the use of our main UK

regulated entity under which a further $20 million would be available in certain exceptional circumstances. This facility is secured against the freehold of the UK regulated entity’s freehold property in Ipswich.

At December 31, 2010, we have $nil outstanding under both the $200 million and the $20 million facilities and $90 million outstanding under our pre-existing $300 million facility.

Total debt, total equity and the capitalization ratio at December 31, 2010 were as follows:

Long-term debt

Short-term debt and current portion of long-term debt

Total debt

Total equity

Capitalization ratio

Liquidity

Our principal sources of liquidity are cash from operations, cash and cash equivalents of $316 million at December 31, 2010 and

$430 million remaining availability under our revolving credit facilities.

We remain committed to our previously stated goals of ongoing debt repayment and returning capital to shareholders.

Consistent with this strategy, we are currently reviewing our debt profile and, subject to prevailing market conditions, may seek to take advantage of attractive financing rates to reduce the cost and extend the maturity profile of our existing debt.

Such actions may include redemption of the entire $500 million in aggregate principal amount of

12.875% senior notes due 2016. If the 2016 senior notes are redeemed, we anticipate that we would incur a one-time pre-tax charge of approximately $180 million relating to the make-whole premium provided under the terms of the indenture governing the notes, as calculated at December 31, 2010.

Based on current market conditions and information available to us at this time, we believe that we have sufficient liquidity to meet our cash needs for at least the next 12 months.

Management structure

Effective January 1, 2011, we have changed our internal reporting structure; Global Markets International, previously reported within our International segment, is now reported in our Global

division. In addition, Mexico, which was previously reported within our International segment, is now reported in our North America segment.

OPERATING RESULTS — GROUP

Commissions and fees

Investment income

Other income

Our methods of calculating these measures may differ from those used by other companies and therefore comparability may be limited.

Revenues for 2010 at $3,339 million were $76 million, or 2 percent higher than in 2009, reflecting organic growth in commissions and fees of 4 percent, offset by a 1 percent adverse year over year impact from foreign currency translation and decreased investment and other income.

Investment income was $38 million for 2010, $12 million lower than 2009 with the impact on investment income of lower interest rates across the globe, particularly on our Euro-denominated deposits, only partially mitigated by our forward hedging program. While we expect this forward hedging program to generate additional income in 2011 compared to current LIBOR based rates, there will be a lower benefit than in 2010 as older, more beneficial hedges, continue to expire. Consequently, we expect investment income to be closer to $30 million in 2011.

Our International and Global operations earn a significant portion of their revenues in currencies other than the US dollar, including the Euro and Pound Sterling. For the year ended December 31,

2010, reported revenues were adversely impacted by the year over year effect of foreign currency translation: in particular due to the strengthening of the US dollar against the Euro, Venezuelan Bolivar Fuerte and Pound Sterling, partly offset by its weakening against the Australian dollar.

Organic growth in commissions and fees was 4 percent for 2010. Global achieved 6 percent growth, driven by good growth in our Reinsurance, Willis Capital Markets & Advisory (WCMA) and Global Specialties businesses. International also achieved 6 percent growth driven by double digit organic growth in Latin America and Asia, together with solid growth in Europe. North America organic revenue growth was flat, as the benefits of double digit new business growth and a change in accounting policy in an acquired specialty business, were offset by the impact of the continued soft market and ongoing weakened economic conditions.

Organic revenue growth by segment is discussed further in ‘Operating Results — Segment Information’ below.

2009 compared with 2008

North America

Revenues for 2009 at $3,263 million were $436 million, or 15 percent higher than in 2008, reflecting a 20 percent benefit from net acquisitions and disposals, principally attributable to HRH, and organic growth in commissions and fees of 2 percent, offset by a 4 percent adverse year over year impact from foreign currency translation, a reduction in legacy HRH contingent commissions and lower investment income.

Investment income was $50 million for 2009, $31 million lower than 2008, with the decrease reflecting significantly lower average interest rates in 2009. The impact of rate decreases on our investment income was partially mitigated by our forward hedging program.

Our International and Global operations earn a significant portion of their revenues in currencies

other than the US dollar. For the year ended December 31, 2009, reported revenues were adversely impacted by the year over year effect of foreign currency translation: in particular due to the strengthening of the US dollar against the Pound Sterling and against the Euro, compared with 2008.

Organic growth in commissions and fees was 2 percent for 2009, despite a negative 3 percent impact from declining premium rates and other market factors. Our overall organic growth comprised good growth in our Global operations and many of our International operations, partly offset by declines in our North America, UK and Irish retail operations reflecting the weak economic environments and soft market conditions experienced in these territories.

Salaries and benefits were 56 percent of revenues for both 2010 and 2009, as the benefits of:

were offset by

Cash retention awards

We have a cash retention award program in place. We started making cash retention awards in 2005 to a small number of employees. With the success of the program, we have expanded it over time to include more staff and we believe it is a contributing factor to the reduction in employee turnover we have seen in recent years.

Salaries and benefits do not reflect the unamortized portion of annual cash retention awards made to employees. Employees must repay a proportionate amount of these cash retention awards if they voluntarily leave our employ (other than in the event of retirement or permanent disability) before a certain time period, currently three years. We make cash payments to our employees in the year we grant these retention awards and recognize these payments ratably over the period they are subject to repayment, beginning in the quarter in which the award is made. A significant majority of the Company’s incentive compensation for non-production compensation is paid in the form of a retention payment versus bonus awards which typically are made for prior service and accrued over the prior service period.

During 2010, we made $196 million of cash retention payments compared with $148 million in 2009. Salaries and benefits in 2010 include $119 million of amortization of cash retention payments made on or before December 31, 2010 compared with $88 million in 2009. As of December 31, 2010 and December 31, 2009, we included $173 million and $98 million, respectively, in other assets on the balance sheet, which represented the unamortized portion of cash retention payments made on or before those dates.

Other expenses

Other expenses were 17 percent of revenues in 2010, compared with 18 percent in 2009, reflecting the benefits of:

Salaries and benefits were 56 percent of revenues for 2009, compared with 58 percent in 2008 reflecting the benefits of:

Effective May 15, 2009, we closed our US defined benefit pension plan to future accrual and recognized a curtailment gain of $12 million in second quarter 2009. As a result the full year 2009 charge for the US plan was $7 million compared with an expected $39 million charge had the plan not been closed to future accrual.

We also suspended the company match for our US 401(k) plan which benefited 2009 by $9 million compared with 2008.

UK salary sacrifice scheme

With effect from April 2009, the Company offered UK employees an alternative basis on which to fund contributions into the UK pension plans. UK employees can now agree to sacrifice an amount of their salary and in return the Company makes additional pension contributions on their behalf, equivalent to the value of the salary sacrificed.

From a payroll tax perspective, this is a more efficient method of making pension contributions.

As a result of this change, the Company made additional pension contributions of $10 million in 2010 and $8 million in 2009, with marginally higher savings in salaries and payroll taxes.

Other expenses were 18 percent of revenues for 2009 compared with 21 percent in 2008, reflecting the benefit of:

We have a program that hedges our sterling cash outflows from our London market operations, a part of which hedges the sterling denominated cash contributions into the UK pension plan. However, we do not hedge against the pension benefits asset or liability recognized for accounting purposes.

The effects of the above increases were partly mitigated by the benefits of our continued focus on cost controls.

Amortization of intangible assets

Amortization of intangible assets of $82 million in 2010 was $18 million lower than in 2009.

The decrease primarily reflects: the year over year benefit of the 2009 accelerated amortization of $7 million relating to the HRH brand name; and the declining charge for the amortization of the HRH customer relationship intangible, which is being amortized in line with the underlying discounted cash flows.

We expect the amortization of intangible assets expense in 2011 to further decrease to approximately $65 million.

Amortization of intangible assets of $100 million in 2009 was $64 million higher than in 2008. The

significant year over year increase was primarily attributable to additional charges of $58 million in 2009 in respect of intangible assets recognized on the HRH acquisition, including $7 million of accelerated amortization relating to the HRH brand name. Following the success of our integration of HRH into our previously existing North America operations, we announced on October 1, 2009 that we were changing the name of our North America operations from Willis HRH to Willis North America. Consequently the intangible asset recognized on the acquisition of HRH relating to the HRH brand name was fully amortized.

Interest expense

Interest expense

Interest expense in 2010 of $166 million was $8 lower than in 2009, as the benefit of the interest expense savings arising from the year over year reduction in average term loan and revolving credit facility balances was partly offset by the effect of the higher coupon payable on the $500 million of 12.875% senior unsecured notes issued in March 2009.

We are reviewing our current debt profile to identify opportunities to reduce our financing costs by taking advantage of current low global interest rates.

Interest expense in 2009 of $174 million was $69 million higher than in 2008. This increase primarily reflects higher average debt levels following the HRH acquisition, but also includes $5 million of premium and costs relating to the early repurchase in September 2009 of $160 million of our 5.125% senior notes due July 2010 at a premium of $27.50 per $1,000 face value.

Income taxes

Income from continuing operations before taxes

Income tax charge

Effective tax rate

The effective tax rate for 2010 of 24 percent was impacted by:


•	an adverse impact from the $12 million charge relating to the devaluation of the Venezuelan currency for which no tax credits are available; and

Excluding these items, the underlying effective tax rate for 2010 was broadly in line with 2009.

The effective tax rate in 2009 was 18 percent compared with 24 percent in 2008. The decrease in rate reflects:

Excluding the benefit of these items, the underlying effective tax rate for 2009 was 26 percent.

Interest in earnings of associates

Interest in earnings of associates, net of tax, in 2010 of $23 million was $10 million lower than in 2009. This fall is primarily driven by the reduction from 49 percent to 31 percent in our ownership interest in Gras Savoye, as part of the reorganization of their capital structure in December 2009. Interest receivable on the vendor financing we provided as part of the capital reorganization is also recorded under this caption.

Interest in earnings of associates, net of tax, was $33 million in 2009, $11 million higher than in 2008, reflecting a year over year increased ownership share in Gras Savoye. As described above, our interest in Gras Savoye subsequently reduced in December 2009 following the reorganization of that company’s capital.

Net income and diluted earnings per share from continuing operations

Net income from continuing operations

Diluted earnings per share from continuing operations

Average diluted number of shares outstanding

Net income from continuing operations for 2010 was $455 million compared with $436 million in 2009, reflecting the benefits of:

Diluted earnings per share from continuing operations for 2010 increased to $2.66 compared to $2.58 in 2009.

Foreign currency translation, excluding the impact of the Venezuelan currency devaluation, had a $0.04 favorable impact on diluted earnings per share. This was more than offset by the $0.07 per diluted share negative impact from the Venezuela currency devaluation in January 2010.

Average share count for 2010 was 171 million compared with 169 million in 2009. The increased share count had a negative $0.03 impact on diluted earnings per share.

Net income from continuing operations for 2009 was $436 million compared with $302 million in 2008. The $134 million increase primarily reflected the $191 million increase in operating income, discussed above, partly offset by the $69 million increase in interest expense.

Diluted earnings per share from continuing operations for 2009 increased to $2.58 compared to $2.04 in 2008 as the benefit of the increased net

income was partly offset by a 21 million increase in average diluted shares outstanding due primarily to the shares issued on October 1, 2008 for the HRH acquisition. The additional shares issued had a negative $0.36 impact on earnings per diluted share in 2009.

Foreign currency translation had a year over year $0.27 positive impact on earnings per diluted share in 2009.

OPERATING RESULTS — SEGMENT INFORMATION

We organize our business into three segments: Global, North America and International. Our Global business provides specialist brokerage and consulting services to clients worldwide for risks arising from specific industries and activities. North America and International comprise our retail

operations and provide services to small, medium and major corporations.

The following table is a summary of our operating results by segment for the three years ended December 31, 2010:

Global

North America

International

Total Retail

Corporate & Other

Total Consolidated

Our Global business comprise Global Specialties, Willis Re, London Market Wholesale, and as of 2010, Willis Capital Markets & Advisory (WCMA).

Faber & Dumas includes Glencairn, our London-based wholesale brokerage operation and our Fine Art, Jewelry and Specie; Special Contingency Risk and Hughes-Gibb units. WCMA provides financial

advice on mergers and acquisitions and capital markets products and may place or underwrite securities.

The following table sets out revenues, organic revenue growth and operating income and margin for the three years ended December 31, 2010:

Organic revenue growth^(a)

Operating margin

Commissions and fees of $873 million were $51 million, or 6 percent, higher in 2010 compared with 2009 which was driven by 6 percent organic revenue growth, with a 1 percent benefit from acquisitions and disposals offset by the impact of foreign currency translation.

Our Reinsurance and Global Specialties businesses both reported mid-single digit organic growth in 2010, driven by good net new business generation despite the adverse impact of the continued difficult rate environment and soft market in many of the specialty classes.

Reinsurance reported strong new business growth across all segments in 2010 and client retention levels remained high. Despite high loss levels earlier in the year, rates remain soft except for Marine and Energy.

Organic growth in Global Specialties was led by strong contributions from Financial and Executive Risks, Construction and Energy, reflecting strong new business, improved retention, targeted hiring of producer talent and global connectivity. However, the operating environment remains tough with depressed world trade and transit volumes, industry

consolidation and pressure on financing of construction projects still evident.

As a result of strong reinsurance underwriting profits in 2009, with the exception of marine and energy, there has been a general but disciplined softening of rates in 2010 which remain a significant headwind for growth.

Our WCMA business also contributed to positive organic revenue growth in 2010, substantially due to a $9 million fee on a single capital markets transaction in the second quarter. WCMA is a transaction oriented business and its results are more variable than some of our other businesses.

Faber & Dumas revenues were slightly lower than 2009, mainly reflecting the soft wholesale market, together with continued pressure on the most economically sensitive lines such as bloodstock, jewelry and fine arts.

Productivity in Global, measured in terms of revenue per FTE employee, increased to $365,000 for 2010 compared with $358,000 for 2009.

Client retention levels remained high at 90 percent for 2010, in line with 2009.

Commissions and fees of $822 million were $38 million, or 5 percent, higher in 2009 compared with 2008 of which 4 percent was attributable to the acquisition of the HRH UK wholesale business, Glencairn and 4 percent to organic revenue growth.

These were partly offset by a 3 percent negative impact from foreign exchange movements.

Net new business growth was 5 percent and there was a 1 percent adverse impact from rates and other market factors. Reinsurance led the growth in net new business. Global Specialties organic revenues

were slightly higher than in 2008, as growth in Marine, Aerospace and Financial and Executive Risks was offset by reductions elsewhere. There was continued softness in most specialty rates although there were some signs of stabilization and firming in some areas, including Aerospace and Energy. The

Faber & Dumas businesses continue to be adversely impacted by the weakening economic environment.

There was a sharp decline in investment income in 2009 compared with 2008 as global interest rates fell markedly in the latter half of 2008 and early 2009.

Operating margin

Operating margin was 30 percent in 2010 compared with 31 percent in 2009. This decrease primarily reflected the adverse impact of foreign currency translation, as the positive effect on our Pound Sterling expense base of a strengthening US dollar, was more than offset by the adverse impact of foreign currency movements on sterling-denominated balances.

Operating margin in Global is impacted by foreign exchange movements as the London Market businesses within our Global operations earn

revenues in US dollars, Pounds Sterling and Euros and primarily incur expenses in Pounds Sterling. In addition, they are exposed to exchange risk on certain sterling-denominated balances.

Excluding the impact of this foreign currency translation, Global’s operating margin remained flat as the benefits of good organic revenue growth and disciplined cost control were offset by the impact of costs associated with continued support of current and future growth.

Operating margin was 31 percent in 2009 compared with 29 percent in 2008. This improvement reflected a significant benefit from foreign currency translation, together with organic revenue growth, particularly driven by our Reinsurance business, and

good cost controls including a reduction in discretionary expenses.

The benefit of these was partly offset by a significant increase in the UK pension expense and a sharp reduction in investment income.

Our North America business provides risk management, insurance brokerage, related risk services and employee benefits brokerage and consulting to a wide array of industry and client segments in the United States and Canada.

Commissions and fees^(a)(b)

Organic revenue growth^(c)

Commissions and fees of $1,359 million were $9 million, or 1 percent, lower for 2010 compared with 2009.

Excluding the $16 million decrease in legacy contingency commissions assumed as part of the HRH acquisition, there was a modest increase in commissions and fees.

Organic revenue growth was flat for 2010 as the benefits of:

Net new business growth includes the benefit of higher standard commissions where these have been negotiated in lieu of contingent commissions. These

higher standard commissions however may not have been negotiated at the same level or be received in the same periods as the related contingent commissions. Furthermore, the business to which they related may not have been renewed.

Despite the small decline in revenues, productivity in North America, measured in terms of revenue per FTE employee, increased to $238,000 for 2010 compared with $227,000 for 2009.

Client retention levels increased to 92 percent for 2010, compared with 91 percent for 2009.

Commissions and fees in North America were 51 percent higher in 2009 compared with 2008 reflecting the uplift from the additional revenues of HRH, partly offset by 3 percent negative organic growth. Our North America operations were significantly adversely impacted by soft market conditions, the weakened US economy and a reduction in project based revenues which more than offset a positive impact from net new business. In particular, our Construction division saw significant declines.

Our primary focus in North America in 2009 was the integration of HRH into our existing operations and the improvement of margin. Additionally, in the second half of the year we refocused our efforts on revenue growth and we believe this led to double digit new business generation in parts of the business during that time period.

Despite the significant decline in revenues, our productivity measured in terms of revenue per FTE employee remained high, with a marginal increase to $227,000 for 2009 compared with $225,000 for 2008.

Operating margin in North America was 23 percent in 2010 compared with 24 percent in 2009, as the benefits of:

were more than offset by

Operating margin in North America was 24 percent in 2009 compared with 15 percent in 2008. The higher margin reflected:

Our International business comprises our retail operations in Eastern and Western Europe, the United Kingdom and Ireland, Asia-Pacific, Russia, the Middle East, South Africa and Latin America. The services provided are focused according to the characteristics of each market and vary across offices, but generally include direct risk

management and insurance brokerage and employee benefits consulting.

Commissions and fees of $1,068 million were $48 million, or 5 percent, higher for 2010 compared with 2009, as the benefits of 6 percent organic revenue growth and 1 percent from the net effect of acquisitions and disposals was partly offset by a 2 percent adverse impact from foreign currency translation. Net new business growth was 9 percent and there was a negative 3 percent impact from rates and other market factors.

A significant part of International’s revenues are earned in currencies other than the US dollar. The US dollar has strengthened against a number of these currencies in 2010 compared with 2009, most notably the Euro, Venezuelan Bolivar Fuerte, Danish Kroner and Pound Sterling. The adverse impact of this strengthening was partly offset by the weakening of the US dollar against the Australian dollar. The net impact of these movements was a 2 percent reduction in 2010 revenues compared to 2009.

There were strong contributions to our organic growth from most regions, led by growth in Latin

America, Asia and Europe. In particular, there was good growth in:

There was further positive growth in our Eastern Europe operations in 2010, driven by a strong contribution from Russia.

Organic revenue growth was also positive in our UK and Irish retail operations, driven by new business growth in the UK as we begin to see signs of an improving economy. Our employee benefits practice, which represents approximately 10 percent of International commissions and fees, continued to perform well in 2010 with growth in the mid single digits.

Productivity in our International business, measured in terms of revenue per FTE employee, increased to

$160,000 for 2010 compared with $156,000 for 2009.

Client retention levels remained high at 92 percent for 2010.

Commissions and fees in International were $35 million, or 3 percent, lower in 2009 compared with 2008 as double digit new business generation in many of our International units was more than offset by an adverse impact from foreign exchange of 8 percent, a 3 percent adverse impact from rates and other market factors, and significantly lower revenues in our UK and Irish retail operations.

A significant part of International’s revenues are earned in currencies other than the US dollar which strengthened significantly in 2009 on a year over year basis against a number of these currencies, most notably the Euro, Pound Sterling, Danish kroner and Australian dollar, consequently reducing

International revenues on a year over year basis when reported in US dollars.

Despite the slowdown of the global economy, International continued its organic growth. Excluding our UK and Irish retail divisions, organic revenue growth was 8 percent in 2009, with Latin America and Asia, led by Brazil, Columbia and China, all reporting strong organic growth. However, our UK and Irish retail division saw a 6 percent revenue decline, reflecting weak local economic conditions.

Client retention levels remained high at approximately 90 percent for 2009.

Operating margin in International was 26 percent in both 2010 and 2009, as the benefits of:

Operating margin in International was 26 percent in 2009 compared with 28 percent in 2008, as the benefits of:

CRITICAL ACCOUNTING ESTIMATES

Our accounting policies are described in Note 2 to the Consolidated Financial Statements. Management considers that the following accounting estimates or assumptions are the most important to the

presentation of our financial condition or operating performance. Management has discussed its critical accounting estimates and associated disclosures with our Audit Committee.

Pension expense

We maintain defined benefit pension plans for employees in the US and UK. Both these plans are now closed to new entrants and, with effect from May 15, 2009 we closed our US defined benefit plan to future accrual. New entrants in the UK are offered the opportunity to join a defined contribution plan and in the United States are offered the opportunity to join a 401(k) plan. We also have smaller defined benefit schemes in Ireland, Germany, Norway and the Netherlands. These International schemes have combined total assets of $125 million and a combined net liability for pension benefits of $10 million as of December 31, 2010. Elsewhere, pension benefits are typically provided through defined contribution plans.

We make a number of assumptions when determining our pension liabilities and pension expense which are reviewed annually by senior management and changed where appropriate. The discount rate will be changed annually if underlying rates have moved whereas the expected long-term return on assets will be changed less frequently as

longer term trends in asset returns emerge or long term target asset allocations are revised. Other material assumptions include rates of participant mortality, the expected long-term rate of compensation and pension increases and rates of employee termination.

We recorded a net pension charge on our UK and US defined benefit pension plans in 2010 of $29 million, compared with $32 million in 2009, a decrease of $3 million.

On our International defined benefit pension plans, we recorded a net pension charge of $6 million in 2010, compared with $10 million in 2009, a decrease of $4 million.

The UK plan charge was $3 million higher as the benefit of higher asset returns from higher asset levels was more than offset by:

The US pension charge was $6 million lower in 2010 compared with 2009 reflecting:

Based on December 31, 2010 assumptions, we expect the net pension charge in 2011 to decrease by: $20 million for the UK plan; $1 million for the US plan; and a net $2 million for the International plans.

UK plan

Estimated 2011 expense

Projected benefit obligation at December 31, 2010

Expected long-term rates of return on plan assets are developed from the expected future returns of the various asset classes using the target asset allocations. The expected long-term rate of return used for determining the net UK pension expense in 2010 remained unchanged at 7.8 percent, equivalent to an expected return in 2010 of $141 million.

Effective January 1, 2011, the expected long-term rate of return was decreased to 7.50%, following a change in the underlying target asset mix.

The expected and actual returns on UK plan assets for the three years ended December 31, 2010 were as follows:

2010

2009

2008

During the latter half of 2008 the value of assets held by our UK pension plan was significantly adversely affected by the turmoil in worldwide markets. The holdings of equity securities were particularly affected in 2008, but have recovered, to some extent, in 2009 and 2010.

Rates used to discount pension plan liabilities at December 31, 2010 were based on yields prevailing at that date of high quality corporate bonds of appropriate maturity. The selected rate used to discount UK plan liabilities was 5.5 percent compared with 5.8 percent at December 31, 2009

with the decrease reflecting a reduction in UK long-term bond rates in the latter part of 2010. This lower discount rate generated an actuarial loss of $84 million at December 31, 2010.

Mortality assumptions at December 31, 2010 were unchanged from December 31, 2009. The mortality assumption is the 100 percent PNA00 table without an age adjustment. As an indication of the longevity assumed, our calculations assume that a UK male retiree aged 65 at December 31, 2010 would have a life expectancy of 22 years.

US plan

The expected long-term rate of return used for determining the net US pension scheme expense in 2010 was 8.0 percent, consistent with 2009. Effective January 1, 2011, the expected long-term rate of return was decreased to 7.50%, following a change in the underlying target asset mix.

The rate used to discount US plan liabilities at December 31, 2010 was 5.6 percent, determined

based on expected plan cash flows discounted using a corporate bond yield curve, a small reduction from 6.1 percent at December 31, 2009.

The expected and actual returns on US plan assets for the three years ended December 31, 2010 were as follows:

As for the UK plan, the 2008 actual return on assets was adversely impacted by the turmoil in worldwide markets.

The mortality assumption at December 31, 2010 is the RP-2000 Mortality Table (blended for annuitants and non-annuitants), projected to 2011 by Scale AA

(December 31, 2009: projected to 2010 by Scale AA). As an indication of the longevity assumed, our calculations assume that a US male retiree aged 65 at December 31, 2010, would have a life expectancy of 19 years.

Intangible assets

Intangible assets represent the excess of cost over the value of net tangible assets of businesses acquired. We classify our intangible assets into three categories:

Client relationships acquired on the HRH acquisition are amortized over twenty years in line with the

pattern in which the economic benefits of the client relationships are expected to be consumed. Over 80 percent of the client relationships intangible will have been amortized after 10 years. Non-compete agreements acquired in connection with the HRH acquisition were amortized over two years on a straight line basis. Intangible assets acquired in connection with other acquisitions are amortized over their estimated useful lives on a straight line basis. Goodwill is not subject to amortization.

To determine the allocation of intangible assets between goodwill and other intangible assets and the estimated useful lives in respect of the HRH

acquisition we considered a report produced by a qualified independent appraiser. The calculation of the allocation is subject to a number of estimates and assumptions. We base our allocation on

assumptions we believe to be reasonable. However, changes in these estimates and assumptions could affect the allocation between goodwill and other intangible assets.

Goodwill impairment review

We review goodwill for impairment annually or whenever events or circumstances indicate impairment may have occurred. Application of the impairment test requires judgment, including:

The fair value of each reporting unit is estimated using a discounted cash flow methodology and, in aggregate, validated against our market capitalization. This analysis requires significant judgments, including:

We base our fair value estimates on assumptions we believe to be reasonable. However, changes in these estimates and assumptions could materially affect the determination of fair value and result in a goodwill impairment.

Our annual goodwill impairment analysis, which we performed during the fourth quarter of 2010, showed the estimated fair value of our reporting units was in excess of their carrying values, and therefore did not result in an impairment charge (2009: $nil, 2008: $nil).

We recognize deferred tax assets and liabilities for the estimated future tax consequences of events attributable to differences between the financial statements carrying amounts of existing assets and liabilities and their respective tax bases and operating and capital loss and tax credit carry-forwards. We estimate deferred tax assets and liabilities and assess the need for any valuation allowances using tax rates in effect for the year in which the differences are expected to be recovered or settled taking into account our business plans and tax planning strategies.

At December 31, 2010, we had gross deferred tax assets of $294 million (2009: $390 million) against which a valuation allowance of $87 million (2009: $92 million) had been recognized. To the extent that:

we may adjust the deferred tax asset considered realizable in future periods. Such adjustments could result in a significant increase or decrease in the effective tax rate and have a material impact on our net income.

Positions taken in our tax returns may be subject to challenge by the taxing authorities upon examination. We recognize the benefit of uncertain tax positions in the financial statements when it is more likely than not that the position will be sustained on examination by the tax authorities upon lapse of the relevant statute of limitations, or when positions are effectively settled. The benefit recognized is the largest amount of tax benefit that has a greater than 50 percent likelihood of being realized on settlement with the tax authority, assuming full knowledge of the position and all relevant facts. The Company adjusts its recognition of

these uncertain tax benefits in the period in which new information is available impacting either the recognition or measurement of its uncertain tax positions. In 2010, $7 million was released relating to uncertain tax positions due to the closure of the statute of limitations on assessments for previously unrecognized tax benefits. There was a similar

$11 million release of uncertain tax positions in 2009. The Company recognizes interest relating to unrecognized tax benefits and penalties within income taxes. Accrued interest and penalties are included within the related tax liability line in the consolidated balance sheet.

Commitments, contingencies and accrued liabilities

We purchase professional indemnity insurance for errors and omissions claims. The terms of this insurance vary by policy year and self-insured risks have increased significantly over recent years. We have established provisions against various actual and potential claims, lawsuits and other proceedings relating principally to alleged errors and omissions in connection with the placement of insurance and

reinsurance in the ordinary course of business. Such provisions cover claims that have been reported but not paid and also claims that have been incurred but not reported. These provisions are established based on actuarial estimates together with individual case reviews and are believed to be adequate in the light of current information and legal advice.

NEW ACCOUNTING STANDARDS

There were no new accounting standards issued during the year that would have a significant impact on the Company’s reporting.

LIQUIDITY AND CAPITAL RESOURCES

Effective December 31, 2010, we changed the presentation of certain items on our balance sheet. Uncollected premiums from insureds and uncollected claims or refunds from insurers, previously reported within accounts receivable, are now recorded as fiduciary assets on the Company’s consolidated balance sheets. Unremitted insurance premiums and

claims (‘fiduciary funds’) are also recorded within fiduciary assets. The obligations to remit these funds, previously reported within accounts payable, are now recorded as fiduciary liabilities on the Company’s consolidated balance sheets. Accordingly, prior year comparatives and commentary below have been recast to reflect this revised presentation.

Consistent with this strategy, we are reviewing our current debt profile and, subject to prevailing market conditions, may seek to take advantage of attractive financing rates to reduce the cost and extend the maturity profile of our existing debt.

Such actions may include redemption of the entire $500 million in aggregate principal amount of 12.875 percent senior notes due 2016. If the 2016 senior notes are redeemed, we anticipate that we would incur a one-time pre-tax charge of approximately $180 million relating to the make-whole premium provided under the terms of the

indenture governing the notes, as calculated at December 31, 2010.

Total debt as of December 31, 2010 decreased to $2.3 billion, compared with $2.4 billion at December 31, 2009.

In 2010, we made $110 million of mandatory repayments against the 5-year term loan, thereby reducing the outstanding balance as at December 31, 2010 to $411 million. We also repurchased the remaining $90 million of 5.125% senior notes due July 2010 and repaid in full a $9 million fixed rate loan due 2010.

In August 2010, we entered into a new revolving credit facility agreement under which a further $200 million is available. This facility is in addition

to the remaining availability under our previously existing $300 million revolving credit facility.

In addition, in June 2010, we entered into an additional facility solely for the use of our main UK regulated entity under which a further $20 million would be available in certain exceptional circumstances. This facility is secured against the freehold of the UK regulated entity’s freehold property in Ipswich.

At December 31, 2010, we have $nil outstanding under both the $200 million and the $20 million facilities and $90 million outstanding under our pre-existing $300 million facility, compared with $nil at December 31, 2009.

At December 31, 2010 the only mandatory debt repayments falling due over the next 12 months are scheduled repayments on our $700 million 5-year term loan totaling $110 million.

Our principal sources of liquidity are cash from operations, cash and cash equivalents of $316 million at December 31, 2010 and remaining availability of $430 million under our revolving credit facilities.

As of December 31, 2010, our short-term liquidity requirements consisted of:

Our long-term liquidity requirements consist of:

We continue to identify and implement further actions to control costs and enhance our operating performance, including future cash flow.

Fiduciary funds

As an intermediary, we hold funds generally in a fiduciary capacity for the account of third parties, typically as the result of premiums received from clients that are in transit to insurers and claims due to clients that are in transit from insurers. We report premiums, which are held on account of, or due from, clients as assets with a corresponding liability due to the insurers. Claims held by, or due to, us which are due to clients are also shown as both assets and liabilities.

Fiduciary funds are generally required to be kept in certain regulated bank accounts subject to guidelines which emphasize capital preservation and liquidity; such funds are not available to service the Company’s debt or for other corporate purposes. Notwithstanding the legal relationships with clients and insurers, the Company is entitled to retain investment income earned on fiduciary funds in accordance with industry custom and practice and, in some cases, as supported by agreements with insureds.

Own funds

As of December 31, 2010, we had cash and cash equivalents of $316 million, compared with $221 million at December 31, 2009 and $430 million

of the total $520 million under our revolving credit facilities remained available to draw.

Operating activities

2010 compared to 2009

Net cash provided by operations was $489 million in 2010 compared with $419 million in 2009.

The $70 million increase in 2010 compared with 2009 primarily reflected the benefits of:

2009 compared to 2008

Net cash provided by operations was $419 million in 2009 compared with $253 million in 2008. The $166 million increase between 2008 and 2009 mainly reflects:

Pension contributions

UK Plan

We made total cash contributions to our UK defined benefit pension plan of $88 million in 2010, (including amounts in respect of the salary sacrifice contributions) compared with $49 million in 2009 and $140 million in 2008.

The additional $39 million cash contribution in 2010 reflects an additional payment required under the UK plan’s funding strategy which we are required to agree with the plan’s trustees.

The funding strategy was agreed in February 2009 and requires full year contributions to the UK plan of $39 million for 2009 through 2012, excluding

amounts in respect of the salary sacrifice scheme. In addition, if certain funding targets were not met at the beginning of any of the following years, 2010 through 2012, a further contribution of $39 million would be required for that year.

In 2010, the additional funding requirement was triggered and we expect to make a similar additional contribution in 2011. A similar, additional contribution may also be required for 2012, depending on actual performance against funding targets at the beginning of 2012.

US Plan

We made total cash contributions to our US defined benefit pension plan of $30 million in 2010, compared with $27 million in 2009 and $8 million in 2008.

For the US plan, expected contributions are the contributions we will be required to make under

US pension legislation based on our December 31, 2010 balance sheet position. We currently expect to contribute $30 million in 2011.

International Plans

We made cash contributions to our International defined benefit pension plans of $12 million in 2010, compared with $6 million in both 2009 and 2008.

In 2011, we expect to contribute approximately $6 million to our International plans.

Investing activities

Total net cash outflow from investing activities was $94 million in 2010 compared with an inflow of $102 million in 2009 mainly reflecting:

Total net cash inflow from investing activities was $102 million in 2009 compared with an outflow of $1,033 million in 2008, primarily reflecting:

Financing activities

Net cash used in financing activities was $293 million in 2010 compared with $516 million in 2009.

The net decrease in cash used in financing activities of $223 million was mainly attributable to:

Net cash used in financing activities was $516 million in 2009 compared with an inflow of $808 million in 2008.

In March 2009, we issued $500 million of senior unsecured notes due 2016 at 12.875%.

We used the $482 million net proceeds of the notes, together with $208 million cash generated from operating activities and $60 million cash in hand, to

pay down the $750 million outstanding on our interim credit facility as of December 31, 2008.

In September 2009, we issued $300 million of 7.0% senior notes due 2019. We then launched a tender offer on September 22, 2009 to repurchase any and all of our $250 million 5.125% senior notes due July 2010 at a premium of $27.50 per $1,000 face value. Notes totaling approximately $160 million were tendered and repurchased on September 29, 2009.

In December 2009, we applied the net cash proceeds of $155 million from the Gras Savoye transaction, together with other cash in hand, to reduce the balance outstanding on the 5-year term loan by approximately $180 million to

$521 million, of which $27 million related to our first mandatory debt repayment.

As of December 31, 2009, there were no amounts outstanding under our $300 million revolving credit facility (2008: $nil).

Share buybacks

We did not buyback any shares in 2010 or 2009. There remains $925 million under the current buyback authorization.

In 2008, we repurchased 2.3 million shares at a cost of $75 million.

In 2009, the Company filed a Tender Offer Statement with the SEC to repurchase for cash options to purchase Company shares. The tender offer expired on August 6, 2009. Approximately 1.6 million options to purchase Company shares were repurchased at an average per share price of $2.04.

Cash dividends paid in 2010 were $176 million compared with $174 million in 2009 and $146 million in 2008.

The $2 million increase in 2010, compared with 2009 is driven by the small increase in share count during the year.

The $28 million increase in 2009, compared with 2008, primarily reflects dividend payments on the 24 million additional shares issued in connection with the fourth quarter 2008 acquisition of HRH.

In February 2011, we declared a quarterly cash dividend of $0.26 per share, an annual rate of $1.04 per share.

Debt obligations and facilities

The Company’s debt and related interest obligations at December 31, 2010 are shown in the above table.

During 2010, the Company entered into a new revolving credit facility agreement under which a further $200 million is available and a new UK facility under which a further $20 million is available. As at December 31, 2010 no drawings had been made on either facility.

These facilities are in addition to the remaining availability of $210 million (2009: $300 million)

under the Company’s previously existing $300 million revolving credit facility.

The only mandatory repayment of debt over the next 12 months is the scheduled repayment of $110 million current portion of the Company’s 5-year term loan. We also have the right, at our option, to prepay indebtedness under the credit facility without further penalty and to redeem the senior notes at our option by paying a ‘make whole’ premium as provided under the applicable debt instrument.

Operating leases

The Company leases certain land, buildings and equipment under various operating lease arrangements. Original non-cancellable lease terms typically are between 10 and 20 years and may contain escalation clauses, along with options that permit early withdrawal. The total amount of the minimum rent is expensed on a straight-line basis over the term of the lease.

As of December 31, 2010, the aggregate future minimum rental commitments under all non-cancellable operating lease agreements are as follows:

2011

2012

2013

2014

2015

Thereafter

Total

The Company leases its London headquarters building under a 25-year operating lease, which expires in 2032. The Company’s contractual obligations in relation to this commitment included in the table above total $744 million (2009: $785 million). Annual rentals are $31 million per year and the Company has subleased approximately 25 percent of the premises under leases up to 15 years. The amounts receivable from subleases, included in the table above, total $87 million (2009: $100 million; 2008: $106 million).

Rent expense amounted to $131 million for the year ended December 31, 2010 (2009: $154 million; 2008: $151 million). The Company’s rental income from subleases was $22 million for the year ended December 31, 2010 (2009: $21 million; 2008: $22 million).

Pensions

Contractual obligations for our pension plans reflect the contributions we expect to make over the next five years into our US and UK plans. These contributions are based on current funding positions and may increase or decrease dependent on the future performance of the two plans.

In the UK, we are required to agree a funding strategy for our UK defined benefit plan with the

plan’s trustees. In February 2009, we agreed to make full year contributions to the UK plan of $39 million for 2009 through 2012, excluding amounts in respect of the salary sacrifice scheme. In addition, if certain funding targets were not met at the beginning of any of the following years, 2010 through 2012, a further contribution of $39 million would be required for that year. In 2010, the

additional funding requirement was triggered and we expect to make a similar additional contribution in 2011. A similar, additional contribution may also be required for 2012, depending on actual performance against funding targets at the beginning of 2012.

The total contributions for all plans are currently estimated to be approximately $125 million in 2011, including amounts in respect of the salary sacrifice scheme.

Guarantees

Guarantees issued by certain of Willis Group Holdings’ subsidiaries with respect to the senior notes and revolving credit facilities are discussed in Note 18 — Debt in these consolidated financial statements.

obligations subject to such guarantees amounted to $855 million and $903 million at December 31, 2010 and 2009, respectively.

In addition, the Company has given guarantees to bankers and other third parties relating principally to letters of credit amounting to $11 million and $5 million at December 31, 2010 and 2009, respectively. Willis Group Holdings also guarantees certain of its UK and Irish subsidiaries’ obligations to fund the UK and Irish defined benefit pension plans.

Other contractual obligations

For certain subsidiaries and associates, the Company has the right to purchase shares (a call option) from co-shareholders at various dates in the future. In addition, the co-shareholders of certain subsidiaries and associates have the right to sell (a put option) their shares to the Company at various dates in the future. Generally, the exercise price of such put options and call options is formula-based (using revenues and earnings) and is designed to reflect fair value. Based on current projections of profitability and exchange rates, the potential amount payable from these options is not expected to exceed $40 million (2009: $49 million).

In December 2009, the Company made a capital commitment of $25 million to Trident V, LP, an investment fund managed by Stone Point Capital. In July 2010, we withdrew from Trident V, LP and subscribed to Trident V Parallel Fund, LP (with the total capital commitment remaining the same). As at December 31, 2010 there had been approximately $1 million of capital contributions.

Other contractual obligations at December 31, 2010 also include the capital lease on the Company’s Nashville property of $63 million, payable from 2012 onwards.

OFF BALANCE SHEET TRANSACTIONS

Apart from commitments, guarantees and contingencies, as disclosed in Note 20 to the Consolidated Financial Statements, the Company has no off-balance sheet arrangements that have, or

are reasonably likely to have, a material effect on the Company’s financial condition, results of operations or liquidity.

Financial Risk Management

We are exposed to market risk from changes in foreign currency exchange rates and interest rates. In order to manage the risk arising from these exposures, we enter into a variety of interest rate and foreign currency derivatives. We do not hold financial or derivative instruments for trading purposes.

A discussion of our accounting policies for financial and derivative instruments is included in Note 2 — Basis of Presentation and Significant Accounting Policies of Notes to the Consolidated Financial Statements, and further disclosure is provided in Note 24 — Derivative Financial Instruments and Hedging Activities.

Foreign exchange risk management

Because of the large number of countries and currencies we operate in, movements in currency exchange rates may affect our results.

We report our operating results and financial condition in US dollars. Our US operations earn revenue and incur expenses primarily in US dollars. Outside the United States, we predominantly generate revenues and expenses in the local currency with the exception of our London market operations which earns revenues in several currencies but incurs expenses predominantly in pounds sterling.

The table below gives an approximate analysis of revenues and expenses by currency in 2010.

Expenses

Our principal exposures to foreign exchange risk arise from:

London market operations

In our London market operations, we earn revenue in a number of different currencies, principally US dollars, pounds sterling, euros and Japanese yen, but incur expenses almost entirely in pounds sterling.

We hedge this risk as follows:

Generally, it is our policy to hedge at least 25 percent of the next 12 months’ exposure in significant currencies. We do not hedge exposures beyond three years.

In addition, we are also exposed to foreign exchange risk on any net sterling asset or liability position in our London market operations. Where this risk relates to short-term cash flows, we hedge all or part of the risk by forward purchases or sales.

However, where the foreign exchange risk relates to any sterling pension assets benefit or liability for pensions benefit, we do not hedge the risk. Consequently, if our London market operations have a significant pension asset or liability, we may be exposed to accounting gains and losses if the US dollar and pounds sterling exchange rate changes. We do, however, hedge the pounds sterling contributions into the pension plan.

Market risk

Translation risk

Outside our US and London market operations, we predominantly earn revenues and incur expenses in the local currency. When we translate the results and net assets of these operations into US dollars for reporting purposes, movements in exchange rates will affect reported results and net assets. For example, if the US dollar strengthens against the euro, the reported results of our Eurozone operations in US dollar terms will be lower.

We do not hedge translation risk.

The table below provides information about our foreign currency forward exchange contracts, which are sensitive to exchange rate risk. The table summarizes the US dollar equivalent amounts of each currency bought and sold forward and the weighted average contractual exchange rates. All forward exchange contracts mature within three years.

Income earned within foreign subsidiaries outside of the UK is generally offset by expenses in the same local currency but the Company does have exposure to foreign exchange movements on the net income

of these entities. The Company does not hedge net income earned within foreign subsidiaries outside of the UK.

Interest rate risk management

Our operations are financed principally by $1,750 million fixed rate senior notes issued by subsidiaries and $411 million under a 5-year term loan facility. Of the fixed rate senior notes,

$350 million are due 2015, $500 million are due 2016, $600 million are due 2017 and $300 million are due 2019. The 5-year term loan facility amortizes at the rate of $27 million per quarter. As of

December 31, 2010 we had access to, $520 million under revolving credit facilities of which $90 million has been drawn. The interest rate applicable to the bank borrowing is variable according to the period of each individual drawdown.

We are also subject to market risk from exposure to changes in interest rates based on our investing activities where our primary interest rate risk arises from changes in short-term interest rates in both US dollars and pounds sterling.

As a consequence of our insurance and reinsurance broking activities, there is a delay between the time we receive cash for premiums and claims and the time the cash needs to be paid. We earn interest on this float, which is included in our consolidated financial statements as investment income.

This float is regulated in terms of access and the instruments in which it may be invested, most of which are short-term in maturity. We manage the interest rate risk arising from this exposure primarily through the use of interest rate swaps. It is our policy that, for currencies with significant balances, a minimum of 25 percent of forecast income arising is hedged for each of the next three years.

During the year ended December 31, 2010, the Company entered into a series of interest rate swaps

for a total notional amount of $350 million to receive a fixed rate and pay a variable rate on a semi-annual basis, with a maturity date of July 15, 2015. The Company has designated and accounts for these instruments as fair value hedges against its $350 million 5.625% senior notes due 2015. The fair values of the interest rate swaps are included within other assets or other liabilities and the fair value of the hedged element of the senior notes is included within the principal amount of the debt.

The table below provides information about our derivative instruments and other financial instruments that are sensitive to changes in interest rates. For interest rate swaps, the table presents notional principal amounts and average interest rates analyzed by expected maturity dates. Notional principal amounts are used to calculate the contractual payments to be exchanged under the contracts. The duration of interest rate swaps varies between one and five years, with re-fixing periods of three to six months. Average fixed and variable rates are, respectively, the weighted-average actual and market rates for the interest hedges in place. Market rates are the rates prevailing at December 31, 2010 or 2009, as appropriate.

Index to Consolidated Financial Statements and Supplementary Data

To the Board of Directors and Stockholders of Willis Group Holdings Public Limited Company

Dublin, Ireland

We have audited the accompanying consolidated balance sheets of Willis Group Holdings Public Limited Company and subsidiaries (the ‘Company’) as of December 31, 2010 and 2009, and the related consolidated statements of operations, changes in equity and comprehensive income, and cash flows for each of the three years in the period ended December 31, 2010. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such consolidated financial statements present fairly, in all material respects, the financial position of Willis Group Holdings Public Limited Company and subsidiaries as of December 31, 2010 and 2009, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2010, in conformity with accounting principles generally accepted in the United States of America.

Willis Group Holdings plc

Willis Group Holdings plc (‘Willis Group Holdings’) and subsidiaries (collectively, the ‘Company’ or the ‘Group’) provide a broad range of insurance and reinsurance broking and risk management consulting services to its clients worldwide, both directly and indirectly through its associates. The Company provides both specialized risk management advisory and consulting services on a global basis to clients engaged in specific industrial and commercial activities, and services to small, medium and major corporates through its retail operations.

In its capacity as an advisor and insurance broker, the Company acts as an intermediary between clients and insurance carriers by advising clients on risk management requirements, helping clients determine the best means of managing risk, and negotiating and placing insurance risk with insurance carriers through the Company’s global distribution network.

Redomicile to Ireland

On September 24, 2009, Willis Group Holdings was incorporated in Ireland, in order to effectuate the change of the place of incorporation of the parent company of the Group. Willis Group Holdings operated as a wholly-owned subsidiary of Willis-Bermuda until December 31, 2009, when the outstanding common shares of Willis-Bermuda were canceled and Willis Group Holdings issued ordinary shares with substantially the same rights and preferences on a one-for-one basis to the holders of the Willis-Bermuda common shares that were canceled. Upon completion of this transaction, Willis Group Holdings replaced Willis-Bermuda as the ultimate parent company and Willis-Bermuda became a wholly-owned subsidiary of Willis Group Holdings. On July 29, 2010 Willis-Bermuda was liquidated.

This transaction was accounted for as a merger between entities under common control; accordingly, the historical financial statements of Willis-Bermuda for periods prior to this transaction are considered to be the historical financial statements of Willis Group Holdings. No changes in capital structure, assets or liabilities resulted from this transaction, other than Willis Group Holdings has provided a guarantee of amounts due under certain borrowing arrangements of one of its subsidiaries as described in Note 28.

Balance sheet presentation

Further to the Company’s redomiciliation to Ireland at the end of 2009, the Group is required to file consolidated financial statements for fiscal year 2010 with the Irish regulator. These consolidated financial statements are prepared under US GAAP and also incorporate additional Irish Companies Act disclosures. To facilitate this process, the Group has decided to incorporate these requirements within its US filings and consequently has recast the presentation of its 2010 and 2009 consolidated balance sheets. In addition, the company has taken the opportunity to provide additional disclosure within the consolidated balance sheet of the Group’s non-fiduciary balances and the further distinction between those assets and liabilities that are expected to be realized within or later than twelve months of the balance sheet date. The Company believes this amended presentation better reflects the Company’s liquidity position and exposures to credit risk.

The 2009 and 2008 consolidated statements of cash flows have been recast to conform with the new balance sheet presentation.

Significant Accounting Policies

These consolidated financial statements conform to accounting principles generally accepted in the United States of America (‘US GAAP’). Presented below are summaries of significant accounting policies followed in the preparation of the consolidated financial statements.

Notes to the financial statements

Principles of Consolidation

The accompanying consolidated financial statements include the accounts of Willis Group Holdings and its subsidiaries, which are controlled through the ownership of a majority voting interest. Intercompany balances and transactions have been eliminated on consolidation.

Foreign Currency Translation

Transactions in currencies other than the functional currency of the entity are recorded at the rates of exchange prevailing at the date of the transaction. Monetary assets and liabilities in currencies other than the functional currency are translated at the rates of exchange prevailing at the balance sheet date and the related transaction gains and losses are reported in the statements of operations. Certain intercompany loans are determined to be of a long-term investment nature. The Company records transaction gains and losses from remeasuring such loans as a component of other comprehensive income.

Upon consolidation, the results of operations of subsidiaries and associates whose functional currency is other than the US dollar are translated into US dollars at the average exchange rate and assets and liabilities are translated at year-end exchange rates. Translation adjustments are presented as a separate component of other comprehensive income in the financial statements and are included in net income only upon sale or liquidation of the underlying foreign subsidiary or associated company.

Use of Estimates

The preparation of financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities as of the dates of the financial statements and the reported amounts of revenues and expenses during the year. In the preparation of these consolidated financial statements, estimates and assumptions have been made by management concerning: the valuation of intangible assets and goodwill (including those acquired through business combinations); the selection of useful lives of fixed and intangible assets; impairment testing; provisions necessary for accounts receivable, commitments and contingencies and accrued liabilities; long-term asset returns, discount rates and mortality rates in order to estimate pension liabilities and pension expense; income tax valuation allowances; and other similar evaluations. Actual results could differ from the estimates underlying these consolidated financial statements.

Cash and Cash Equivalents

Cash and cash equivalents primarily consist of time deposits with original maturities of three months or less.

Fiduciary Assets and Fiduciary Liabilities

In its capacity as an insurance agent or broker, the Company collects premiums from insureds and, after deducting its commissions, remits the premiums to the respective insurers; the Company also collects claims or refunds from insurers on behalf of insureds.

Fiduciary Assets

Effective December 31, 2010, the Company changed the presentation of its fiduciary balances. Uncollected premiums from insureds and uncollected claims or refunds from insurers, previously held within accounts receivable, are now recorded as fiduciary assets on the Company’s consolidated balance sheets. Unremitted insurance premiums and claims (‘fiduciary funds’) are also recorded within fiduciary assets.

Fiduciary Liabilities

The obligations to remit these funds to insurers or insureds are recorded as fiduciary liabilities on the Company’s consolidated balance sheets. The period for which the Company holds such funds is dependent upon the date the insured remits the payment of the premium to the Company and the date the Company is required to forward such payment to the insurer. Balances arising from insurance brokerage transactions are reported as separate assets or liabilities unless such balances are due to or from the same party and a right of offset exists, in which case the balances are recorded net.

Fiduciary Funds

Fiduciary funds represent unremitted premiums received from insureds and unremitted claims received from insurers. Fiduciary funds are generally required to be kept in certain regulated bank accounts subject to guidelines which emphasize capital preservation and liquidity; such funds are not available to service the Company’s debt or for other corporate purposes. Notwithstanding the legal relationships with clients and insurers, the Company is entitled to retain investment income earned on fiduciary funds in accordance with industry custom and practice and, in some cases, as supported by agreements with insureds.

Included in fiduciary funds are cash and cash equivalents consisting primarily of time deposits. The debt securities are classified as available-for-sale. Accordingly, they are recorded at fair market value with unrealized holding gains and losses reported, net of tax, as a component of other comprehensive income.

In certain instances, the Company advances premiums, refunds or claims to insurance underwriters or insureds prior to collection. Such advances are made from fiduciary funds and are reflected in the accompanying consolidated balance sheets as fiduciary assets.

Accounts Receivable

Accounts receivable are stated at estimated net realizable values. Allowances are recorded, when necessary, in an amount considered by management to be sufficient to meet probable future losses related to uncollectible accounts.

Fixed Assets

Fixed assets are stated at cost less accumulated depreciation. Expenditures for improvements are capitalized; repairs and maintenance are charged to expenses as incurred. Depreciation is computed using the straight-line method based on the estimated useful lives of assets.

Depreciation on buildings and long leaseholds is calculated over the lesser of 50 years or the lease term. Depreciation on leasehold improvements is calculated over the lesser of the useful life of the assets or the remaining lease term. Depreciation on furniture and equipment is calculated based on a range of 3 to 10 years.

Recoverability of Fixed Assets

Long-lived assets are tested for recoverability whenever events or changes in circumstance indicate that their carrying amounts may not be recoverable. An impairment loss is recognized if the carrying amount of a long-lived asset is not recoverable and exceeds its fair value. Recoverability is determined based on the undiscounted cash flows expected to result from the use and eventual disposition of the asset or asset group. Long-lived assets and certain identifiable intangible assets to be disposed of are reported at the lower of carrying amount or fair value less cost to sell.

Operating Leases

Rentals payable on operating leases are charged straight line to expenses over the lease term as the rentals become payable.

Goodwill and Other Intangible Assets

Goodwill represents the excess of the cost of businesses acquired over the fair market value of identifiable net assets at the dates of acquisition. The Company reviews goodwill for impairment annually and whenever facts or circumstances indicate that the carrying amounts may not be recoverable. In testing for impairment, the fair value of each reporting unit is compared with its carrying value, including goodwill. If the carrying amount of a reporting unit exceeds its fair value, the amount of an impairment loss, if any, is calculated by comparing the implied fair value of reporting unit goodwill with the carrying amount of that goodwill.

Acquired intangible assets are amortized over the following periods:

Acquired intangible assets

Acquired HRH customer relationships

Acquired HRH non-compete agreements

Acquired HRH trade names

Amortizable intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that their carrying amounts may not be recoverable.

Investments in Associates

Investments are accounted for using the equity method of accounting if the Company has the ability to exercise significant influence, but not control, over the investee. Significant influence is generally deemed to exist if the Company has an equity ownership in the voting stock of the investee between 20 and 50 percent, although other factors, such as representation on the Board of Directors and the impact of commercial arrangements, are considered in determining whether the equity method of accounting is appropriate. Under the equity method of accounting the investment is carried at cost of acquisition, plus the Company’s equity in undistributed net income since acquisition, less any dividends received since acquisition.

The Company periodically reviews its investments in associates for which fair value is less than cost to determine if the decline in value is other than temporary. If the decline in value is judged to be other than temporary, the cost basis of the investment is written down to fair value. The amount of any write-down is included in the statements of operations as a realized loss.

All other equity investments where the Company does not have the ability to exercise significant influence are accounted for by the cost method. Such investments are not publicly traded.

Derivative Financial Instruments

The Company uses derivative financial instruments for other than trading purposes to alter the risk profile of an existing underlying exposure. Interest rate swaps are used to manage interest risk exposures. Forward foreign currency exchange contracts are used to manage currency exposures arising from future income and expenses. The fair values of derivative contracts are recorded in other assets and other liabilities. The effective portions of changes in the fair value of derivatives that qualify for hedge accounting as cash flow hedges are recorded in other comprehensive income. Amounts are reclassified from other comprehensive income into earnings when the hedged exposure affects earnings. If the derivative is designated as and qualifies as an

effective fair value hedge, the changes in the fair value of the derivative and of the hedged item attributable to the hedged risk are recognized in earnings. Changes in fair value of derivatives that do not qualify for hedge accounting, together with any hedge ineffectiveness on those that do qualify, are recorded in other operating expenses or interest expense as appropriate.

Income Taxes

The Company recognizes deferred tax assets and liabilities for the estimated future tax consequences of events attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating and capital loss and tax credit carry forwards. Deferred tax assets and liabilities are measured using enacted rates in effect for the year in which the differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of changes in tax rates is recognized in the statement of operations in the period in which the enactment date changes. Deferred tax assets are reduced through the establishment of a valuation allowance at such time as, based on available evidence, it is more likely than not that the deferred tax assets will not be realized. The Company adjusts valuation allowances to measure deferred tax assets at the amount considered realizable in future periods if the Company’s facts and assumptions change. In making such determination, the Company considers all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax planning strategies and recent financial operations.

Positions taken in the Company’s tax returns may be subject to challenge by the taxing authorities upon examination. The Company recognizes the benefit of uncertain tax positions in the financial statements when it is more likely than not that the position will be sustained on examination by the tax authorities upon lapse of the relevant statute of limitations, or when positions are effectively settled. The benefit recognized is the largest amount of tax benefit that is greater than 50 percent likely to be realized on settlement with the tax authorities, assuming full knowledge of the position and all relevant facts. The Company adjusts its recognition of these uncertain tax benefits in the period in which new information is available impacting either the recognition or measurement of its uncertain tax positions. These differences will be reflected as increases or decreases to income tax expense in the period in which they are determined.

Changes in tax laws and rates could also affect recorded deferred tax assets and liabilities in the future. Management is not aware of any such changes that would have a material effect on the Company’s results of operations, cash flows or financial position.

The Company recognizes interest and penalties relating to unrecognized tax benefits within income taxes.

Provisions for Liabilities

The Company is subject to various actual and potential claims, lawsuits and other proceedings. The Company records liabilities for such contingencies including legal costs when it is probable that a liability has been incurred before the balance sheet date and the amount can be reasonably estimated. To the extent such losses can be recovered under the Company’s insurance programs, estimated recoveries are recorded when losses for insured events are recognized and the recoveries are likely to be realized. Significant management judgment is required to estimate the amounts of such contingent liabilities and the related insurance recoveries. The Company analyzes its litigation exposure based on available information, including consultation with outside counsel handling the defense of these matters, to assess its potential liability. Contingent liabilities are not discounted.

Pensions

The Company has two principal defined benefit pension plans which cover the majority of employees in the United States and United Kingdom. Both these plans are now closed to new entrants. New entrants in the

United Kingdom are offered the opportunity to join a defined contribution plan and in the United States are offered the opportunity to join a 401(k) plan. In addition, there are smaller plans in certain other countries in which the Company operates. Elsewhere, pension benefits are typically provided through defined contribution plans.

Defined benefit plans

The net periodic cost of the Company’s defined benefit plans are measured on an actuarial basis using the projected unit credit method and several actuarial assumptions. The most significant of which are the discount rate and the expected long-term rate of return on plan assets. Other material assumptions include rates of participant mortality, the expected long-term rate of compensation and pension increases and rates of employee termination. Gains and losses occur when actual experience differs from actuarial assumptions. If such gains or losses exceed ten percent of the greater of plan assets or plan liabilities the Company amortizes those gains or losses over the average remaining service period of the employees.

In accordance with US GAAP the Company records on the balance sheet the funded status of its pension plans based on the projected benefit obligation.

Defined contribution plans

Contributions to the Company’s defined contribution plans are recognized as they fall due. Differences between contributions payable in the year and contributions actually paid are shown as either other assets or other liabilities in the consolidated balance sheets.

Share-Based Compensation

The Company accounts for share-based compensation as follows:

Revenue Recognition

Revenue includes insurance commissions, fees for services rendered, certain commissions receivable from insurance carriers, investment income and other income.

Brokerage income and fees negotiated instead of brokerage are recognized at the later of policy inception date or when the policy placement is complete. Commissions on additional premiums and adjustments are recognized as and when advised.

Fees for risk management and other services are recognized as the services are provided. Negotiated fee arrangements for an agreed period covering multiple insurance placements, the provision of risk management and/or other services are determined, contract by contract, on the basis of the relative fair value of the services completed and the services yet to be rendered. The Company establishes contract cancellation reserves where appropriate: at December 31, 2010, 2009 and 2008, such amounts were not material.

Investment income is recognized as earned.

Other income comprises gains on disposal of intangible assets, which primarily arise on the disposal of books of business. Although the Company is not in the business of selling intangible assets (mainly books of business), from time to time the Company will dispose of a book of business (a customer list) or other intangible assets that do not produce adequate margins or fit with the Company’s strategy.

The average number of persons, including Executive Directors, employed by the Company is as follows:

North America

International

Severance Costs

The Company incurred severance costs of $15 million in the year ended December 31, 2010 (2009: $24 million; 2008: $26 million) relating to approximately 550 positions (2009: 450 positions; 2008: 100 positions) that have been, or are in the process of being, eliminated as part of the Company’s continuing focus on managing expense. Severance costs for these employees were recognized pursuant to the terms of their existing benefit arrangements or employment agreements.

Cash Retention Awards

The Company makes annual cash retention awards to its employees. Employees must repay a proportionate amount of these awards if they voluntarily leave the Company’s employ (other than in the event of retirement or permanent disability) before a certain time period, currently up to three years. The Company makes cash payments to its employees in the year it grants these retention awards and recognizes these payments ratably over the period they are subject to repayment, beginning in the quarter in which the award is made. The unamortized portion of cash retention awards is recorded within other assets.

The following table sets out the amount of cash retention awards made and the related amortization of those awards for the years ended December 31, 2010, 2009 and 2008:

Cash retention awards made

Amortization of cash retention awards included in salaries and benefits

Unamortized cash retention awards totaled $173 million as of December 31, 2010 (2009: $98 million; 2008: $41 million).

On December 31, 2010, the Company had a number of open share-based compensation plans, which provide for the grant of time-based and performance-based options, restricted stock units and various other share-based grants to employees. All of the Company’s share-based compensation plans under which any options, restricted stock units or other share-based grants are outstanding as at December 31, 2010 are described below. The compensation cost that has been charged against income for those plans for the year ended December 31, 2010 was $47 million (2009: $39 million; 2008: $40 million). The total income tax benefit recognized in the statement of operations for share-based compensation arrangements for the year ended December 31, 2010 was $14 million (2009: $12 million; 2008: $12 million).

2001 Share Purchase and Option Plan

This plan, which was established on May 3, 2001, provides for the granting of time-based options, restricted stock units and various other share-based grants at fair market value to employees of the Company. There are 25,000,000 shares available for grant under this plan. Options are exercisable on a variety of dates, including from the first, second, third, sixth or eighth anniversary of grant, although for certain options the exercisable date may accelerate depending on the achievement of certain performance goals. The Board of Directors has adopted several sub-plans under the 2001 plan to provide employee sharesave schemes in the UK, Ireland and internationally. Unless terminated sooner by the Board of Directors, the 2001 Plan (and all sub-plans) will expire 10 years after the date of its adoption. That termination will not affect the validity of any grant outstanding at that date.

2008 Share Purchase and Option Plan

This plan, which was established on April 23, 2008, provides for the granting of time and performance-based options, restricted stock units and various other share-based grants at fair market value to employees of the Company. There are 8,000,000 shares available for grant under this plan. Options are exercisable on a variety of dates, including from the third, fourth or fifth anniversary of grant. Unless terminated sooner by the Board of Directors, the 2008 Plan will expire 10 years after the date of its adoption. That termination will not affect the validity of any grant outstanding at that date.

HRH Option Plans

Options granted under the Hilb Rogal and Hamilton Company 2000 Stock Incentive Plan (‘HRH 2000 Plan’) and the Hilb Rogal & Hobbs Company 2007 Stock Incentive Plan (the ‘HRH 2007 Plan’) were converted into options to acquire shares of Willis Group Holdings. No further grants are to be made under the HRH 2000 Plan. Willis is authorized to grant equity awards under the HRH 2007 Plan until 2017 to employees who were formerly employed by HRH and to new employees who have joined Willis or one of its subsidiaries since October 1, 2008, the date that the acquisition of HRH was completed.

Employee Stock Purchase Plans

The Company has adopted the Willis Group Holdings 2001 North America Employee Share Purchase Plan, expiring May 31, 2011 and the Willis Group Holdings 2010 North America Employee Stock Purchase Plan. They provide certain eligible employees to the Company’s subsidiaries in the US and Canada the ability to contribute payroll deductions to the purchase of Willis Shares at the end of each offering period.

The Company may also issue 245,000 Shares to directors upon exercise of options.

Option Valuation Assumptions

The fair value of each option is estimated on the date of grant using the Black-Scholes option pricing model that uses the assumptions noted in the following table. Expected volatility is based on historical volatility of the Company’s stock. With effect from January 1, 2006, the Company uses the simplified method set out in Accounting Standard Codification (‘ASC’) 718-10-S99 to derive the expected term of options granted. The risk-free rate for periods within the expected life of the option is based on the US Treasury yield curve in effect at the time of grant.

The total intrinsic value of options exercised during the year ended December 31, 2010 was $8 million (2009: $3 million; 2008: $7 million). At December 31, 2010 there was $17 million of total unrecognized compensation cost related to nonvested share-based compensation arrangements under time-based stock option plans; that cost is expected to be recognized over a weighted average period of 1 year.

The weighted average grant-date fair value of performance-based options granted during the year ended December 31, 2010 was $7.11 (2009: $5.89; 2008: $9.37). The total intrinsic value of options exercised during the year ended December 31, 2010 was $nil (2009: $1 million; 2008: $3 million).

A summary of restricted stock unit activity under the Plans at December 31, 2010, and changes during the year then ended is presented below:

Nonvested shares (restricted stock units)

Vested

The total number of restricted stock units vested during the year ended December 31, 2010, was 744,633 shares at an average share price of $32.17 (2009: 550,224 shares at an average share price of $24.53). At December 31, 2010 there was $15 million of total unrecognized compensation cost related to nonvested share-based compensation arrangements under the plan: that cost is expected to be recognized over a weighted average period of 1 year.

Total auditors’ remuneration

Total proceeds for 2010 were $4 million, comprising $2 million relating to 2010 disposals of operations and $2 million of deferred proceeds relating to prior year. A loss on disposal of $2 million is recorded in the consolidated statements of operations for the year ended December 31, 2010.

Total proceeds from the disposal of operations for 2009 were $315 million, including $281 million for 18 percent of the Group’s 49 percent interest in Gras Savoye and $39 million for 100 percent of Bliss & Glennon. A gain on disposal of $13 million is recorded in the statement of consolidated operations for the year ended December 31, 2009, of which $10 million relates to Gras Savoye as shown below.

On December 17, 2009, the Company completed a leveraged transaction with the original family shareholders of Gras Savoye and Astorg Partners, a private equity fund, to reorganize the capital of Gras Savoye (‘December 2009 leveraged transaction’), its principal investment in associates. The Company, the family shareholders and Astorg now own equal stakes of 31 percent in Gras Savoye and have equal representation of one third of the voting rights on its board. The remaining shareholding is held by a large pool of Gras Savoye managers and minority shareholders.

As a result of the December 2009 leveraged transaction the Company recognized a gain of $10 million in the consolidated statement of operations from the reduction of its interest in Gras Savoye from 49 percent to 31 percent. The Company received total proceeds of $281 million, comprising cash and interest bearing vendor loans and convertible bonds issued by Gras Savoye. An analysis of the proceeds and the calculation of the gain is as follows:

Proceeds:

Cash

Vendor Loans

Convertible Bonds

At December 31, 2010, the Company had valuation allowances of $87 million (2009: $92 million) to reduce its deferred tax assets to estimated realizable value. The valuation allowances at December 31, 2010 relate to the deferred tax assets arising from UK capital loss carryforwards ($49 million) and other net operating losses ($1 million), which have no expiration date and to the deferred tax assets arising from US State net operating losses ($37 million). Capital loss carryforwards can only be offset against future UK capital gains.

At December 31, 2010, the Company had deferred tax assets of $207 million (2009: $298 million), net of the valuation allowance. Management believes, based upon the level of historical taxable income and projections for future taxable income, it is more likely than not that the Company will realize the benefits of these deductible differences, net of the valuation allowance. However, the amount of the deferred tax asset considered realizable could be adjusted in the future if estimates of taxable income are revised.

The Company recognizes deferred tax balances related to the undistributed earnings of subsidiaries when the Company expects that it will recover those undistributed earnings in a taxable manner, such as through receipt of dividends or sale of the investments. The Company does not, however, provide for income taxes on the unremitted earnings of certain other subsidiaries where, in management’s opinion, such earnings have been indefinitely reinvested in those operations, or will be remitted either in a tax free liquidation or as dividends

with taxes substantially offset by foreign tax credits. It is not practical to determine the amount of unrecognized deferred tax liabilities for temporary differences related to these investments.

Unrecognized tax benefits

Total unrecognized tax benefits as at December 31, 2010, totaled $13 million. During the next 12 months it is reasonably possible that the Company will recognize approximately $1 million of tax benefits related to the release of provisions no longer required due to either settlement through negotiation or closure of the statute of limitations on assessment.

A reconciliation of the beginning and ending amounts of unrecognized tax benefits is as follows:

Balance at January 1

Reductions due to a lapse of the applicable statute of limitation

Adjustment to assessment of acquired HRH balances

Increase of HRH opening balances

Other movements

Balance at December 31

All of the unrecognized tax benefits at December 31, 2010 would, if recognized, favorably affect the effective tax rate in future periods.

The Company files tax returns in the various tax jurisdictions in which it operates. The 2006 US tax year closed in 2010 upon the expiration of the statute of limitations on assessment. US tax returns have been filed timely. The Company has received notice that the IRS will be examining the 2009 tax return. The Company has not extended the federal statute of limitations for assessment in the US.

All UK tax returns have been filed timely and are in the normal process of being reviewed, with HM Revenue & Customs making enquiries to obtain additional information. There are no material ongoing enquiries in relation to filed UK returns other than in relation to the quantification of foreign tax reliefs available on the remittance of foreign earnings.

Basic and diluted earnings per share are calculated by dividing net income attributable to Willis Group Holdings by the average number of shares outstanding during each period. The computation of diluted earnings per share reflects the potential dilution that could occur if dilutive securities and other contracts to issue shares were exercised or converted into shares or resulted in the issue of shares that then shared in the net income of the Company.

For the year ended December 31, 2010, time-based and performance-based options to purchase 11.5 million and 9.4 million (2009: 13.4 million and 8.9 million; 2008: 16.9 million and 5.8 million) shares, respectively, and 1.8 million restricted stock units (2009: 2.2 million; 2008: 1.4 million), respectively, were outstanding.

Basic and diluted earnings per share are as follows:

Basic average number of shares outstanding

Dilutive effect of potentially issuable shares

Diluted average number of shares outstanding

Basic earnings per share:

Continued operations

Discontinued operations

Net income attributable to Willis Group Holdings shareholders

Dilutive effect of potentially issuable shares

Diluted earnings per share:

Options to purchase 13.9 million shares for the year ended December 31, 2010 were not included in the computation of the dilutive effect of stock options because the effect was antidilutive (2009: 16.1 million shares; 2008: 22.1 million shares).

The Company collects premiums from insureds and, after deducting its commissions, remits the premiums to the respective insurers; the Company also collects claims or refunds from insurers on behalf of insureds. Uncollected premiums from insureds and uncollected claims or refunds from insurers (‘fiduciary receivables’) are recorded as fiduciary assets on the Company’s consolidated balance sheets. Unremitted insurance premiums and claims (‘fiduciary funds’) are also recorded within fiduciary assets.

Fiduciary assets therefore comprise both receivables and funds held in a fiduciary capacity.

Fiduciary funds, consisting primarily of time deposits with original maturities of less than or equal to three months, were $1,764 million as of December 31, 2010 (2009: $1,683 million). Accrued interest on funds is recorded as other assets.

Consolidation of fiduciary funds

The financial statements as at December 31, 2010 and 2009 reflect the consolidation of one Variable Interest Entity (‘VIE’), a UK non-statutory trust that was established in January 2005 following the introduction of statutory regulation of insurance in the UK by the Financial Services Authority. The regulation requires that all fiduciary funds collected by an insurance broker such as the Company be paid into a non-statutory trust designed to give additional credit protection to the clients and insurance carriers of the Company. This trust restricts the financial instruments in which such funds may be invested and affects the timing of transferring commission from fiduciary funds to own funds.

As of December 31, 2010, the fair value of the fiduciary funds in the VIE was $976 million (2009: $903 million) and the fair value of the associated liabilities was $976 million (2009: $903 million). There are no assets of the Company that serve as collateral for the VIE.

Goodwill represents the excess of the cost of businesses acquired over the fair market value of identifiable net assets at the dates of acquisition. Goodwill is not amortized but is subject to impairment testing annually and whenever facts or circumstances indicate that the carrying amounts may not be recoverable.

The Company’s annual goodwill impairment tests for 2010 and prior years have not resulted in an impairment charge (2009: $nil; 2008: $nil).

When a business entity is sold, goodwill is allocated to the disposed entity based on the fair value of that entity compared to the fair value of the reporting unit in which it is included.

The changes in the carrying amount of goodwill by operating segment for the years ended December 31, 2010 and 2009 are as follows:

The Company holds a number of investments which it accounts for using the equity method. The Company’s approximate interest in the outstanding stock of the more significant associates is as follows:

Al-Futtaim Willis Co. L.L.C.

GS & Cie Groupe

The Company’s principal investment as of December 31, 2010 and 2009 is GS & Cie Groupe (‘Gras Savoye’), France’s leading insurance broker.

The Company’s original investment in Gras Savoye was made in 1997, when it acquired a 33 percent ownership interest. Between 1997 and December 2009 this interest was increased by a series of incremental investments to 49 percent.

On December 17, 2009, the Company completed a leveraged transaction with the original family shareholders of Gras Savoye and Astorg Partners, a private equity fund, to reorganize the capital of Gras Savoye (‘December 2009 leveraged transaction’). The Company, the original family shareholders and Astorg now own equal stakes of 31 percent in Gras Savoye and have equal representation of one third of the voting rights on its board. The remaining shareholding is held by a large pool of Gras Savoye managers and minority shareholders.

A put option that was in place prior to the December 2009 leveraged transaction, and which could have increased the Company’s interest to 90 percent, has been canceled and the Company now has a new call option to purchase 100 percent of the capital of Gras Savoye. If the Company does not waive the new call option before April 30, 2014, then it must exercise the new call option in 2015 or the other shareholders may initiate procedures to sell Gras Savoye. Except with the unanimous consent of the supervisory board and other customary exceptions, the parties are prohibited from transferring any shares of Gras Savoye until 2015. At the end of this period, shareholders are entitled to pre-emptive and tag-along rights.

As a result of the December 2009 leveraged transaction the Company recognized a gain of $10 million in the consolidated statement of operations for the year ended December 31, 2009 from the reduction of its interest in Gras Savoye from 49 percent to 31 percent. The Company received total proceeds of $281 million, comprising cash and interest bearing vendor loans and convertible bonds issued by Gras Savoye. See Note 6 — Net (Loss) Gain on Disposal of Operations for an analysis of the proceeds and the calculation of the gain.

The carrying amount of the Gras Savoye investment as of December 31, 2010 includes goodwill of $88 million (2009: $94 million) and interest bearing vendor loans and convertible bonds issued by Gras Savoye of $44 million and $78 million respectively (2009: $46 million and $78 million, respectively).

As of December 31, 2010 and 2009, the Company’s other investments in associates, individually and in the aggregate, were not material to the Company’s operations.

The Company maintains two principal defined benefit pension plans that cover the majority of our employees in the United States and United Kingdom. Both of these plans are now closed to new entrants. New entrants in the United Kingdom are offered the opportunity to join a defined contribution plan and in the United States are offered the opportunity to join a 401(k) plan. In addition to the Company’s UK and US defined benefit pension plans, the Company has several smaller defined benefit pension plans in certain other countries in

which it operates. Elsewhere, pension benefits are typically provided through defined contribution plans. It is the Company’s policy to fund pension costs as required by applicable laws and regulations.

Effective May 15, 2009, the Company closed the US defined benefit plan to future accrual. Consequently, a curtailment gain of $12 million was recognized during the year ended December 31, 2009.

At December 31, 2010, the Company recorded, on the Consolidated Balance Sheets:

Expected return on plan assets

The expected return on plan assets was determined on the basis of the weighted-average of the expected future returns of the various asset classes, using the target allocations shown below. The expected returns on UK plan assets are: UK and foreign equities 8.85 percent, debt securities 5.10 percent and real estate 5.80 percent. The expected returns on US plan assets are: US and foreign equities 10.25 percent and debt securities 4.75 percent.

The Company’s pension plan asset allocations based on fair values were as follows:

Equity securities

Debt securities

Hedge funds

Real estate

Cash

The Company’s investment policy includes a mandate to diversify assets and the Company invests in a variety of asset classes to achieve that goal. The UK plan’s assets are divided into 10 separate portfolios according to asset class and managed by 11 investment managers. The broad target allocations are UK and foreign equities (59 percent), debt securities (20 percent), hedge funds (16 percent) and real estate (5 percent). The US plan’s assets are currently invested in 17 funds representing most standard equity and debt security classes. The broad target allocations are US and foreign equities (61 percent) and debt securities (39 percent).

Fair Value Hierarchy

The fair value hierarchy has three levels based on the reliability of the inputs used to determine fair value:

The following tables present, at December 31, 2010 and 2009, for each of the fair value hierarchy levels, the Company’s UK pension plan assets that are measured at fair value on a recurring basis.

The UK plan’s real estate investment comprises UK property and infrastructure investments which are valued by the fund manager taking into account cost, independent appraisals and market based comparable data. The UK plan’s hedge fund investments are primarily invested in various ‘fund of funds’ and are valued based on net asset values calculated by the fund and are not publicly available. Liquidity is typically monthly and is subject to liquidity of the underlying funds.

Non US Government bonds

Equity securities comprise:

Fixed income securities comprise US, UK and other Government Treasury Bills, loan stock, index linked loan stock and UK and other corporate bonds which are typically valued using quoted market prices.

As a result of the inherent limitations related to the valuations of the Level 3 investments, due to the unobservable inputs of the underlying funds, the estimated fair value may differ significantly from the values that would have been used had a market for those investments existed.

The following table summarizes the changes in the UK pension plan’s Level 3 assets for the years ended December 31, 2010 and 2009:

Purchases, sales, issuances and settlements, net

Unrealized gains relating to instruments still held at end of year

Foreign exchange

In 2011, the Company expects to contribute $89 million to the UK plan, of which $11 million is in respect of salary sacrifice contributions, and $30 million to the US plan.

The following benefit payments, which reflect expected future service, as appropriate, are estimated to be paid by the UK and US defined benefit pension plans:

2016-2020

Willis North America has a 401(k) plan covering all eligible employees of Willis North America and its subsidiaries. The plan allows participants to make pre-tax contributions which the Company, at its discretion may match. During 2009, the Company has decided not to make any matching contributions other than for former HRH employees whose contributions were matched up to 75 percent under the terms of the acquisition. All investment assets of the plan are held in a trust account administered by independent trustees. The Company’s 401(k) matching contributions for 2010 were $nil million (2009: $5 million; 2008: $8 million).

International defined benefit pension plans

In addition to the Company’s UK and US defined benefit pension plans, the Company has several smaller defined benefit pension plans in certain other countries in which it operates.

A $10 million pension benefit liability (2009: $30 million) has been recognized in respect of these schemes.

The following schedules provide information concerning the Company’s international defined benefit pension plans:

The following schedule provides other information concerning the Company’s international defined benefit pension plans:

The determination of the expected long-term rate of return on the international plan assets is dependent upon the specific circumstances of each individual plan. The assessment may include analyzing historical investment performance, investment community forecasts and current market conditions to develop expected returns for each asset class used by the plans.

The Company’s international pension plan asset allocations at December 31, 2010 based on fair values were as follows:

The investment policies for the international plans vary by jurisdiction but are typically established by the local pension plan trustees, where applicable, and seek to maintain the plans’ ability to meet liabilities of the plans as they fall due and to comply with local minimum funding requirements.

Fixed income securities comprise overseas Government loan stock which is typically valued using quoted market prices. Real estate investment comprises overseas property and infrastructure investments which are valued by the fund manager taking into account cost, independent appraisals and market based comparable data. Derivative instruments are valued using an income approach typically using swap curves as an input.

Assets classified as Level 3 investments did not materially change during the year ended December 31, 2010. In 2011, the Company expects to contribute $7 million to the international plans.

The following benefit payments, which reflect expected future service, as appropriate, are estimated to be paid by the international defined benefit pension plans:

Debt issuance

During the year ended December 31, 2010, the Company entered into a series of interest rate swaps for a total notional amount of $350 million to receive a fixed rate and pay a variable rate on a semi-annual basis, with a maturity date of July 15, 2015. The Company has designated and accounts for these instruments as fair value hedges against its $350 million 5.625% senior notes due 2015. The fair values of the interest rate swaps are included within other assets or other liabilities and the fair value of the hedged element of the senior notes is included within long-term debt.

The 5-year term loan facility bears interest at LIBOR plus 2.250% and is repayable at $27 million per quarter, with a final payment of $115 million due in the fourth quarter of 2013. Drawings under the revolving $300 million credit facility bear interest at LIBOR plus 2.250% and the facility expires on October 1, 2013. On August 9, 2010, Willis North America, Inc. agreed an additional revolving credit facility for $200 million. Drawings on this facility bear interest at LIBOR plus a margin of either 1.750% or 2.750% depending upon

the currency of the loan. This margin applies while the Company’s debt rating remains BBB-/Baa3. This facility expires on October 1, 2013. As at December 31, 2010 no drawings had been made on the facility.

On June 22, 2010, a further revolving credit facility of $20 million was put in place which bears interest at LIBOR plus 1.700% until 2012 and LIBOR plus 1.850% thereafter. The facility expires on December 22, 2012. As at December 31, 2010 no drawings had been made on the facility.

The $20 million revolving credit facility put in place on June 22, 2010 is solely for the use of our main UK regulated entity and would be available in certain exceptional circumstances. This facility is secured against the freehold of the UK regulated entity’s freehold property in Ipswich.

In March 2009, Trinity Acquisition plc issued 12.875% senior notes due 2016 in an aggregate principal amount of $500 million to Goldman Sachs Mezzanine Partners which generated net proceeds of $482 million. These proceeds were used to refinance part of an interim credit facility.

In September 2009, Willis North America, Inc. issued $300 million of 7.000% senior notes due 2019. A tender offer was launched on September 22, 2009, to repurchase any and all of the $250 million 5.125% senior notes due July 2010 at a premium of $27.50 per $1,000 face value. Notes totaling approximately $160 million were tendered and repurchased.

The agreements relating to our 5-year term loan facility and the Willis North America, Inc. revolving credit facility contain requirements to maintain maximum levels of consolidated funded indebtedness in relation to consolidated EBITDA and minimum levels of consolidated EBITDA to consolidated fixed charges, subject to certain adjustments. In addition, the agreements relating to our credit facilities and senior notes include, in the aggregate, covenants relating to the delivery of financial statements, reports and notices, limitations on liens, limitations on sales and other disposals of assets, limitations on indebtedness and other liabilities, limitations on sale and leaseback transactions, limitations on mergers and other fundamental changes, maintenance of property, maintenance of insurance, nature of business, compliance with applicable laws, maintenance of corporate existence and rights, payment of taxes and access to information and properties. At December 31, 2010, the Company was in compliance with all covenants.

Lines of credit

The Company also has available $2 million (2009: $7 million) in lines of credit, of which $nil was drawn as of December 31, 2010 (2009: $nil).

Analysis of interest expense

The following table shows an analysis of the interest expense for the years ended December 31:

Debt obligations and facilities

These facilities are in addition to the remaining availability of $210 million (2009: $300 million) under the Company’s previously existing $300 million revolving credit facility.

Operating leases

In the UK, we are required to agree a funding strategy for our UK defined benefit plan with the plan’s trustees. In February 2009, we agreed to make full year contributions to the UK plan of $39 million for 2009 through 2012, excluding amounts in respect of the salary sacrifice scheme. In addition, if certain funding targets were not met at the beginning of any of the following years, 2010 through 2012, a further contribution of $39 million would be required for that year. In 2010, the additional funding requirement was triggered and we expect to make a similar additional contribution in 2011. A similar, additional contribution may also be required for 2012, depending on actual performance against funding targets at the beginning of 2012.

Guarantees

Certain of Willis Group Holdings’ subsidiaries have given the landlords of some leasehold properties occupied by the Company in the United Kingdom and the United States guarantees in respect of the performance of the lease obligations of the subsidiary holding the lease. The operating lease obligations subject to such guarantees amounted to $855 million and $903 million at December 31, 2010 and 2009, respectively.

Other contractual obligations

Claims, Lawsuits and Other Proceedings

In the ordinary course of business, the Company is subject to various actual and potential claims, lawsuits, and other proceedings relating principally to alleged errors and omissions in connection with the placement of insurance and reinsurance. Similar to other corporations, the Company is also subject to a variety of other claims, including those relating to the Company’s employment practices. Some of the claims, lawsuits and other proceedings seek damages in amounts which could, if assessed, be significant.

Errors and omissions claims, lawsuits, and other proceedings arising in the ordinary course of business are covered in part by professional indemnity or other appropriate insurance. The terms of this insurance vary by policy year and self-insured risks have increased significantly in recent years. In respect of self-insured risks, the Company has established provisions which are believed to be adequate in the light of current information and legal advice, and the Company adjusts such provisions from time to time according to developments.

On the basis of current information, the Company does not expect that the actual claims, lawsuits and other proceedings, to which the Company is subject, or potential claims, lawsuits, and other proceedings relating to matters of which it is aware will ultimately have a material adverse effect on the Company’s financial condition, results of operations or liquidity. Nonetheless, given the large or indeterminate amounts sought in certain of these actions, and the inherent unpredictability of litigation and disputes with insurance companies, it is possible that an adverse outcome in certain matters could, from time to time, have a material adverse effect on the Company’s results of operations or cash flows in particular quarterly or annual periods.

The material actual or potential claims, lawsuits and other proceedings, of which the Company is currently aware, are:

Inquiries and Investigations

In connection with the investigation launched by the New York State Attorney General in April 2004 concerning, among other things, contingent commissions paid by insurers to insurance brokers, in April 2005, the Company entered into an Assurance of Discontinuance (‘Original AOD’) with the New York State Attorney General and the Superintendent of the New York Insurance Department and paid $50 million to

eligible clients. As part of the Original AOD, the Company also agreed not to accept contingent compensation and to disclose to customers any compensation the Company will receive in connection with providing policy placement services to the customer. The Company also resolved similar investigations launched by the Minnesota Attorney General, the Florida Attorney General, the Florida Department of Financial Services, and the Florida Office of Insurance Regulation for amounts that were not material to the Company.

Similarly, in August 2005 HRH entered into an agreement with the Attorney General of the State of Connecticut (the ‘CT Attorney General’) and the Insurance Commissioner of the State of Connecticut to resolve all issues related to their investigations into certain insurance brokerage and insurance agency practices and to settle a lawsuit brought in August 2005 by the CT Attorney General alleging violations of the Connecticut Unfair Trade Practices Act and the Connecticut Unfair Insurance Practices Act. As part of this settlement, HRH agreed to take certain actions including establishing a $30 million national fund for distribution to certain clients; enhancing disclosure practices for agency and broker clients; and declining to accept contingent compensation on brokerage business. The Company has cooperated fully with other similar investigations by the regulators and/or attorneys general of other jurisdictions, some of which have been concluded with no indication of any finding of wrongdoing.

On February 16, 2010, the Company entered into the Amended and Restated Assurance of Discontinuance with the Attorney General of the State of New York and the Amended and Restated Stipulation with the Superintendent of Insurance of the State of New York (the ‘Amended and Restated AOD’) on behalf of itself and its subsidiaries named therein. The Amended and Restated AOD was effective February 11, 2010 and supersedes and replaces the Original AOD.

The Amended and Restated AOD specifically recognizes that the Company has substantially met its obligations under the Original AOD and ends many of the requirements previously imposed. It relieves the Company of a number of technical compliance obligations that have imposed significant administrative and financial burdens on its operations. The Amended and Restated AOD no longer limits the types of compensation the Company can receive and has lowered the compensation disclosure requirements.

The Amended and Restated AOD requires the Company to: (i) in New York, and each of the other 49 states of the United States, the District of Columbia and U.S. territories, provide compensation disclosure that will, at a minimum, comply with the terms of the applicable regulations, as may be amended from time to time, or the provisions of the AOD that existed prior to the adoption of the Amended and Restated AOD; and (ii) maintain its compliance programs and continue to provide appropriate training to relevant employees in business ethics, professional obligations, conflicts of interest, and antitrust and trade practices compliance. In addition, in placing, renewing, consulting on or servicing any insurance policy, it prohibits the Company from directly or indirectly (a) accepting from or requesting of any insurer any promise or commitment to use any of the Company’s brokerage, agency, producing or consulting services in exchange for production of business to such insurer or (b) knowingly place, renew or consult on or service a client’s insurance business through a wholesale broker in a manner that is contrary to the client’s best interest.

In 2006, the European Commission issued questionnaires pursuant to its Sector Inquiry or, in respect of Norway, the European Free Trade Association Surveillance Authority, related to insurance business practices, including compensation arrangements for brokers, to at least 150 European brokers including our operations in nine European countries. The Company filed responses to the European Commission and the European Free Trade Association Surveillance Authority questionnaires. The European Commission reported on a final basis on September 25, 2007, expressing concerns over potential conflicts of interest in the industry relating to remuneration and binding authorities and also over the nature of the coinsurance market. The Company co-operated with both the European Free Trade Association Surveillance Authority and the European Commission to resolve issues raised in its final report regarding coinsurance as required of the industry by the European Commission.

Since August 2004, the Company and HRH (along with various other brokers and insurers) have been named as defendants in purported class actions in various courts across the United States. All of these actions have been consolidated into a single action in the US District Court for the District of New Jersey (‘MDL’). There are two amended complaints within the MDL, one that addresses employee benefits (‘EB Complaint’) and one that addresses all other lines of insurance (‘Commercial Complaint’). HRH was a named defendant in the EB Complaint, but has since been voluntarily dismissed. HRH is a named defendant in the Commercial Complaint. The Company is a named defendant in both MDL complaints. Each of the EB Complaint and the Commercial Complaint seeks monetary damages, including punitive damages, and equitable relief and makes allegations regarding the practices and conduct that have been the subject of the investigation of state attorneys general and insurance commissioners, including allegations that the brokers have breached their duties to their clients by entering into contingent compensation agreements with either no disclosure or limited disclosure to clients and participated in other improper activities. The complaints also allege the existence of a conspiracy among insurance carriers and brokers and allege violations of federal antitrust laws, the federal Racketeer Influenced and Corrupt Organizations (‘RICO’) statute and the Employee Retirement Income Security Act of 1974 (‘ERISA’). In separate decisions issued in August and September 2007, the antitrust and RICO Act claims were dismissed with prejudice and the state claims were dismissed without prejudice from the Commercial Complaint. In January 2008, the Judge dismissed the ERISA claims with prejudice from the EB Complaint and the state law claims without prejudice.

Plaintiffs filed a notice of appeal regarding the dismissal of the antitrust and RICO claims and oral arguments on this appeal were heard in April 2009. In August 2010, the United States Court of Appeals for the Third Circuit issued its decision on plaintiffs’ appeal. The Court upheld the dismissal of all claims against HRH and the Company, with the exception of one RICO related claim. The Court remanded the RICO claim to the District Court for further consideration. The District Judge is allowing HRH and the Company (and the other affected defendants) to submit new motions to dismiss the remanded RICO claim. The motion has been filed, but a decision is not expected until sometime in 2011. Additional actions could be brought in the future by individual policyholders. The Company disputes the allegations in all of these suits and has been and intends to continue to defend itself vigorously against these actions. The outcomes of these lawsuits, however, including any losses or other payments that may occur as a result, cannot be predicted at this time.

Reinsurance Market Dispute

Various legal proceedings are pending, have concluded or may commence between reinsurers, reinsureds and in some cases their intermediaries, including reinsurance brokers, relating to personal accident excess of loss reinsurance for the years 1993 to 1998. The proceedings principally concern allegations by reinsurers that they have sustained substantial losses due to an alleged abnormal ‘spiral’ in the market in which the reinsurance contracts were placed, the existence and nature of which, as well as other information, was not disclosed to them by the reinsureds or their reinsurance broker.

A ‘spiral’ is a market term for a situation in which reinsureds and reinsurers reinsure each other with the effect that the same loss or portion of that loss moves through the market multiple times.

The reinsurers concerned have taken the position that, despite their decisions to underwrite risks or a group of risks, they are no longer bound by their reinsurance contracts. As a result, they have stopped settling claims and are seeking to recover claims already paid. The Company also understands that there have been arbitration awards in relation to a ‘spiral’, among other things, in which the reinsurer successfully argued that it was no longer bound by parts of its reinsurance program. Willis Limited, the Company’s principal insurance brokerage subsidiary in the United Kingdom, acted as the reinsurance broker or otherwise as intermediary, but not as an underwriter, for numerous personal accident reinsurance contracts. Due to the small number of reinsurance brokers generally, Willis Limited also utilized other brokers active in this market as sub-agents, including brokers who are parties to the legal proceedings described above, for certain contracts and may be

responsible for any errors and omissions they may have made. In July 2003, one of the reinsurers received a judgment in the English High Court against certain parties, including a sub-broker Willis Limited used to place two of the contracts involved in this trial. Although neither the Company nor any of its subsidiaries were a party to this proceeding or any arbitration, Willis Limited entered into tolling agreements with certain of the principals to the reinsurance contracts tolling the statute of limitations pending the outcome of proceedings between the reinsureds and reinsurers.

Two former clients of Willis Limited, American Reliable Insurance Company and one of its associated companies (collectively, ‘ARIC’), and CNA Insurance Company Limited and two of its associated companies (‘CNA’) terminated their respective tolling agreements with Willis Limited and commenced litigation in September 2007 and January 2008, respectively, in the English Commercial Court against Willis Limited. ARIC alleged conspiracy between a former Willis Limited employee and the ARIC underwriter as well as negligence and CNA alleged deceit and negligence by the same Willis Limited employee both in connection with placements of personal accident reinsurance in the excess of loss market in London and elsewhere. On June 9, 2009, Willis Limited entered into a settlement agreement under which Willis Limited paid a total of $139 million to ARIC, which was covered by errors and omissions insurance. On September 11, 2009, Willis Limited entered into a settlement agreement under which Willis Limited paid a total of $130 million to CNA. The Company has substantially collected and believes it will collect in full the $130 million required under the CNA settlement agreement from errors and omissions insurers. The settlements include no admission of wrongdoing by any party. Each party also realized and waived all claims it may have against any of the other parties arising out of or in connection with the subject matter of the litigation.

Various arbitrations relating to reinsurance continue and, from time to time, the principals request co-operation from the Company and suggest that claims may be asserted against the Company. Such claims may be made against the Company if reinsurers do not pay claims on policies issued by them. The Company cannot predict at this time whether any such claims will be made or the damages that may be alleged.

Gender Discrimination Class Action

In March 2008, the Company settled an action in the United States District Court for the Southern District of New York commenced against the Company in 2001 on behalf of an alleged nationwide class of present and former female officer and officer equivalent employees alleging that the Company discriminated against them on the basis of their gender and seeking injunctive relief, money damages, attorneys’ fees and costs. Although the Court had denied plaintiffs’ motions to certify a nationwide class or to grant nationwide discovery, it certified a class of approximately 200 female officers and officer equivalent employees based in the Company’s offices in New York, New Jersey and Massachusetts. The settlement agreement provides for injunctive relief and a monetary payment, including the amount of attorney fees plaintiffs’ counsel are entitled to receive, which was not material to the Company. In December 2006, a former female employee, whose motion to intervene in the class action was denied, filed a purported class action in the United States District Court, Southern District of New York, with almost identical allegations as those contained in the suit that was settled in 2008, except seeking a class period of 1998 to the time of trial (the class period in the settled suit was 1998 to the end of 2001). The Company’s motion to dismiss this suit was denied and the Court did not grant the Company permission to immediately file an appeal from the denial of its motion to dismiss. The parties are in the discovery phase of the litigation. The suit was amended to include one additional plaintiff and another filed an arbitration demand that includes a class allegation.

In January 2011, the Company reached an agreement with plaintiffs on a monetary settlement to settle all class claims and the claims of the individual named plaintiffs as well as the plaintiff that filed an arbitration demand. The amount of this settlement is not material. However, before this matter can be settled in its entirety, the parties must reach agreement on any injunctive measures the Company will implement and the Court must approve all terms of the settlement.

World Trade Center

The Company acted as the insurance broker, but not as an underwriter, for the placement of both property and casualty insurance for a number of entities which were directly impacted by the September 11, 2001, destruction of the World Trade Center complex, including Silverstein Properties LLC, which acquired a 99-year leasehold interest in the twin towers and related facilities from the Port Authority of New York and New Jersey in July 2001. Although the World Trade Center complex insurance was bound at or before the July 2001 closing of the leasehold acquisition, consistent with standard industry practice, the final policy wording for the placements was still in the process of being finalized when the twin towers and other buildings in the complex were destroyed on September 11, 2001. There have been a number of lawsuits in the United States between the insured parties and the insurers for several placements and other disputes may arise in respect of insurance placed by us which could affect the Company including claims by one or more of the insureds that the Company made culpable errors or omissions in connection with our brokerage activities. However, the Company does not believe that our role as broker will lead to liabilities which in the aggregate would have a material adverse effect on our results of operations, financial condition or liquidity.

Stanford Financial Group

On July 2, 2009, a putative class action complaint, captioned Troice, et al. v. Willis of Colorado, Inc., et al., C.A. No. 3:09-CV-01274-N, was filed in the U.S. District Court for the Northern District of Texas against Willis Group Holdings, Willis of Colorado, Inc. and a Willis associate, among others, relating to the collapse of The Stanford Financial Group (’Stanford’), for which Willis of Colorado, Inc. acted as broker of record on certain lines of insurance. The complaint generally alleged that the defendants actively and materially aided Stanford’s alleged fraud by providing Stanford with certain letters regarding coverage that they knew would be used to help retain or attract actual or prospective Stanford client investors. The complaint alleged that these letters, which contain statements about Stanford and the insurance policies that the defendants placed for Stanford, contained untruths and omitted material facts and were drafted in this manner to help Stanford promote and sell its allegedly fraudulent certificates of deposit. The putative class consisted of Stanford investors in Mexico and the complaint asserted various claims under Texas statutory and common law and sought actual damages in excess of $1 billion, punitive damages and costs. On August 12, 2009, the plaintiffs filed an amended complaint, which, notwithstanding the addition of certain factual allegations and Texas common law claims, largely mirrored the original and sought the same relief.

On July 17, 2009, a putative class action complaint, captioned Ranni v. Willis of Colorado, Inc., et al., C.A. No. 09-22085, was filed against Willis Group Holdings and Willis of Colorado, Inc. in the U.S. District Court for the Southern District of Florida, relating to the same alleged course of conduct as the Troice complaint described above. Based on substantially the same allegations as the Troice complaint, but on behalf of a putative class of Venezuelan and other South American Stanford investors, the Ranni complaint asserts a claim under Section 10(b) of the Securities Exchange Act of 1934 and Rule 10b-5 thereunder, as well as various claims under Florida statutory and common law, and seeks damages in an amount to be determined at trial and costs.

On or about July 24, 2009, a motion was filed by certain individuals (collectively, the ‘Movants’) with the U.S. Judicial Panel on Multidistrict Litigation (the ‘JPML’) to consolidate and coordinate in the Northern District of Texas nine separate putative class actions — including the Troice and Ranni actions described above, as well as other actions against various Stanford-related entities and individuals and the Commonwealth of Antigua and Barbuda — relating to Stanford and its allegedly fraudulent certificates of deposit.

On August 6, 2009, a putative class action complaint, captioned Canabal, et al. v. Willis of Colorado, Inc., et al., C.A. No. 3:09-CV-01474-D, was filed against Willis Group Holdings, Willis of Colorado, Inc. and the same Willis associate, among others, also in the Northern District of Texas, relating to the same alleged course

of conduct as the Troice complaint described above. Based on substantially the same allegations as the Troice complaint, but on behalf of a putative class of Venezuelan investors, the Canabal complaint asserted various claims under Texas statutory and common law and sought actual damages in excess of $1 billion, punitive damages, attorneys’ fees and costs.

On or about August 10, 2009, the Movants filed with the JPML a Notice of Related Action that referred the Canabal action to the JPML. On October 6, 2009, the JPML ruled on the transfer motion, transferring seven of the subject actions (including the Troice and Ranni actions) — i.e., the original nine actions minus two that had since been dismissed — for consolidation or coordination in the Northern District of Texas. On October 27, 2009, the parties to the Canabal action stipulated to the designation of that action as a related case and properly part of the new Stanford MDL proceeding in the Northern District of Texas.

On September 14, 2009, a complaint, captioned Rupert, et al. v. Winter, et al., Case No. 2009C115137, was filed on behalf of 97 Stanford investors against Willis Group Holdings, Willis of Colorado, Inc. and the same Willis associate, among others, in Texas state court (Bexar County). Based on substantially the same allegations as the Troice complaint, the Rupert complaint asserts claims under the Securities Act of 1933, as well as various Texas statutory and common law claims, and seeks rescission, damages, special damages and consequential damages of $79.1 million, treble damages of $237.4 million under the Texas Insurance Code, attorneys’ fees and costs. On October 20, 2009, certain defendants, including Willis of Colorado, Inc., (i) removed the Rupert action to the U.S. District Court for the Western District of Texas, (ii) notified the JPML of the pendency of this additional ‘tag-along’ action and (iii) moved to stay the action pending a determination by the JPML as to whether it should be transferred to the Northern District of Texas for consolidation or coordination with the other Stanford-related actions. In November 2009, the JPML issued a conditional transfer order (the ‘CTO’) for the transfer of the Rupert action to the Northern District of Texas. On December 22, 2009, the plaintiffs filed a motion to vacate, or alternatively stay, the CTO, to which Willis of Colorado, Inc. responded on January 4, 2010. On April 1, 2010, the JPML denied the plaintiffs’ motion to vacate the CTO and issued a final transfer order for the transfer of the Rupert action to the Northern District of Texas.

On December 18, 2009, the parties to the Troice and Canabal actions stipulated to the consolidation of those actions and, on December 31, 2009, the plaintiffs therein, collectively, filed a Second Amended Class Action Complaint, which largely mirrors the Troice and Canabal predecessor complaints, but seeks relief on behalf of a worldwide class of Stanford investors. Also on December 31, 2009, the plaintiffs in the Canabal action filed a Notice of Dismissal, dismissing the Canabal action without prejudice. On February 25, 2010, the defendants filed motions to dismiss the Second Amended Class Action Complaint in the consolidated Troice/Canabal action. Those motions are currently pending. On May 24, 2010, the plaintiffs in the consolidated Troice/Canabal action filed a motion for leave to file a Third Amended Class Action Complaint, which, among other things, adds several Texas statutory claims. That motion is also currently pending.

On September 16, 2010, a complaint, captioned Casanova, et al. v. Willis of Colorado, Inc., et al., C.A. No. 3:10-CV-01862-O, was filed on behalf of seven Stanford investors against Willis Group Holdings, Willis Limited, Willis of Colorado, Inc. and the same Willis associate, among others, also in the Northern District of Texas. Although this is not a class action, the Casanova complaint is based on substantially the same allegations as the Second Amended Class Action Complaint in the consolidated Troice/Canabal action. The Casanova complaint asserts various claims under Texas statutory and common law and seeks actual damages in excess of $5 million, punitive damages, attorneys’ fees and costs.

The defendants have not yet responded to the Ranni or Rupert or Casanova complaints.

Additional actions could be brought in the future by other investors in certificates of deposit issued by Stanford and its affiliates. The Company disputes these allegations and intends to defend itself vigorously

against these actions. The outcomes of these actions, however, including any losses or other payments that may occur as a result, cannot be predicted at this time.

St. Jude

In January 2009, Willis of Minnesota, Inc. was named as a third party defendant in a lawsuit between American Insurance Company (‘AIC’) and St. Jude Medical, Inc. (‘St. Jude’) pending in the United States District Court, District of Minnesota, that arose out of a products liability insurance program for St. Jude in which AIC provided one layer of insurance and the Company acted as the broker. St. Jude sought a judgment against AIC requiring AIC to pay its policy limits of $50 million plus interest and costs for certain personal injury claims filed against St. Jude and denied by AIC. To the extent there was a finding that AIC does not have to provide coverage for these claims, St. Jude alternatively alleged standard errors and omissions claims against the Company for the same amount.

On December 22, 2010, the parties to this suit entered into a settlement agreement that fully resolves all claims in the lawsuit. Under the settlement agreement, the Company agreed to make and has already made an immaterial one-time payment to St. Jude. As part of the settlement agreement, each party has also fully and completely released and waived all claims it may have against any of the other parties arising out of or in connection with the subject matter of the litigation. The settlement includes no admissions of wrongdoing by any party. The lawsuit was dismissed with prejudice on January 3, 2011.

Primary risks managed by derivative financial instruments

The main risks arising from the Company’s financial instruments are interest rate risk, liquidity risk, foreign currency risk and credit risk. The Company’s board of directors reviews and agrees policies for managing each of these risks as summarized below.

The Company enters into derivative transactions (principally interest rate swaps and forward foreign currency contracts) in order to manage interest rate and currency risks arising from the Company’s operations and its sources of finance. The Company does not hold financial or derivative instruments for trading purposes.

Interest Rate Risk

As a result of the Company’s operating activities, the Company receives cash for premiums and claims which it deposits in short-term investments denominated in US dollars and other currencies. The Company earns interest on these funds, which is included in the Company’s financial statements as investment income. These funds are regulated in terms of access and the instruments in which they may be invested, most of which are short-term in maturity. In order to manage interest rate risk arising from these financial assets, the Company enters into interest rate swaps to receive a fixed rate of interest and pay a variable rate of interest fixed in the various currencies related to the short-term investments. The use of interest rate contracts essentially converts groups of short-term variable rate investments to fixed rates.

The fair value of these contracts is recorded in other assets and other liabilities. For contracts that qualify as cash flow hedges for accounting purposes, the effective portions of changes in fair value are recorded as a component of other comprehensive income.

At December 31, 2010 and 2009, the company had the following derivative financial instruments that were designated as cash flow hedges of interest rate risk:

2010

US dollar

Pounds sterling

Euro

2009

The Company’s operations are financed principally by $1,750 million fixed rate senior notes and $411 million under a 5-year term loan facility. Of the fixed rate senior notes $350 million are due 2015, $500 million are due 2016, $600 million are due 2017 and $300 million are due 2019. The Company also has access to $520 million under three revolving credit facilities; as of December 31, 2010 $90 million was drawn from the 5-year $300 million revolving credit facility. All debt is issued by subsidiaries of the Company.

The interest rates applicable to the borrowings under the 5-year term loan and the revolving credit facilities vary according to LIBOR on the date of individual drawdowns.

During the year ended December 31, 2010, the Company entered into a series of interest rate swaps for a total notional amount of $350 million to receive a fixed rate and pay a variable rate on a semi-annual basis, with a maturity date of July 15, 2015. At the year end the weighted average fixed rate payable was 2.71% and variable rate receivable was 2.04%. The Company has designated and accounts for these instruments as fair value hedges against its $350 million 5.625% senior notes due 2015. The fair values of the interest rate swaps are included within other assets or other liabilities and the fair value of the hedged element of the senior notes is included within long-term debt.

At December 31, 2010 and 2009, the Company’s interest rate swaps were all designated as hedging instruments.

Liquidity Risk

The Company’s objective is to ensure that it has the ability to generate sufficient cash either from internal or external sources, in a timely and cost-effective manner, to meet its commitments as they fall due. The Company’s management of liquidity risk is embedded within its overall risk management framework. Scenario analysis is continually undertaken to ensure that the Company’s resources can meet its liquidity requirements. These resources are supplemented by access to $520 million under three revolving credit facilities.

Foreign Currency Risk

The Company’s primary foreign exchange risks arise:

The foreign exchange risks in its London market operations are hedged as follows:

The Company does not hedge net income earned within foreign subsidiaries outside of the UK.

The fair value of foreign currency contracts is recorded in other assets and other liabilities. For contracts that qualify as accounting hedges, changes in fair value resulting from movements in the spot exchange rate are recorded as a component of other comprehensive income whilst changes resulting from a movement in the time value are recorded in interest expense. For contracts that do not qualify for hedge accounting, the total change in fair value is recorded in interest expense. Amounts held in comprehensive income are reclassified into earnings when the hedged exposure affects earnings.

At December 31, 2010 and 2009, the Company’s foreign currency contracts were all designated as hedging instruments.

The table below summarizes by major currency the contractual amounts of the Company’s forward contracts to exchange foreign currencies for pounds sterling in the case of US dollars and US dollars for Euro and Japanese yen. Foreign currency notional amounts are reported in US dollars translated at contracted exchange rates.

Credit Risk and Concentrations of Credit Risk

Credit risk represents the loss that would be recognized at the reporting date if counterparties failed to perform as contracted and from movements in interest rates and foreign exchange rates. The Company does not anticipate non-performance by counterparties. The Company generally does not require collateral or other security to support financial instruments with credit risk; however, it is the Company’s policy to enter into master netting arrangements with counterparties as practical.

Concentrations of credit risk that arise from financial instruments exist for groups of customers or counterparties when they have similar economic characteristics that would cause their ability to meet contractual obligations to be similarly affected by changes in economic or other conditions. Financial instruments on the balance sheet that potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents, accounts receivable and derivatives which are recorded at fair value.

The Company maintains a policy providing for the diversification of cash and cash equivalent investments and places such investments in an extensive number of financial institutions to limit the amount of credit risk exposure. These financial institutions are monitored on an ongoing basis for credit quality predominantly using information provided by credit agencies.

Concentrations of credit risk with respect to receivables are limited due to the large number of clients and markets in which the Company does business, as well as the dispersion across many geographic areas. Management does not believe significant risk exists in connection with the Company’s concentrations of credit as of December 31, 2010.

For interest rate swaps all components of each derivative’s gain or loss were included in the assessment of hedge effectiveness. For foreign exchange contracts only the changes in fair value resulting from movements in the spot exchange rate are included in this assessment.

At December 31, 2010 the Company estimates there will be $7 million of net derivative gains reclassified from accumulated comprehensive income into earnings within the next twelve months.

Fair Value Hedges

The table below presents the effects of derivative financial instruments in fair value hedging relationships on the consolidated statements of operations for the year ended December 31, 2010. The Company did not have any derivative financial instruments in fair value hedging relationships during 2009 and 2008.

Year ended December 31, 2010

Interest rate swaps

All components of each derivative’s gain or loss were included in the assessment of hedge effectiveness.

The Company’s principal financial instruments, other than derivatives, comprise the fixed rate senior notes, the 5-year term loan, a revolving credit facility, fiduciary assets and liabilities, and cash deposits.

The following table presents, for each of the fair-value hierarchy levels, the Company’s assets and liabilities that are measured at fair value on a recurring basis:

The estimated fair value of the Company’s financial instruments held or issued to finance the Company’s operations is summarized below. Certain estimates and judgments were required to develop the fair value amounts. The fair value amounts shown below are not necessarily indicative of the amounts that the Company would realize upon disposition nor do they indicate the Company’s intent or ability to dispose of the financial instrument.

Cash and cash equivalents

Fiduciary funds — restricted (included within Fiduciary assets)

Derivative financial instruments⁽ⁱ⁾

Short-term debt

Long-term debt

Derivative financial instruments

The following methods and assumptions were used by the Company in estimating its fair value disclosure for financial instruments:

Cash and Cash Equivalents — The estimated fair value of these financial instruments approximates their carrying values due to their short maturities.

During the periods presented, the Company operated through three segments: Global; North America and International. Global provides specialist brokerage and consulting services to clients worldwide for specific industrial and commercial activities and is organized by specialism. North America and International predominantly comprise our retail operations which provide services to small, medium and major corporates, accessing Global’s specialist expertise when required.

The accounting policies of the operating segments are consistent with those described in Note 2 — Basis of Presentation and Significant Accounting Policies.

On July 1, 2005, Willis North America Inc. (‘Willis North America’) issued senior notes totaling $600 million under its February 2004 registration statement. On March 28, 2007, Willis North America issued further senior notes totaling $600 million under its June 2006 registration statement. On September 29, 2009, Willis North America issued senior notes totaling $300 million under its June 2009 registration statement (Note 18 — Debt).

Until December 22, 2010, all direct obligations under the senior notes were jointly and severally, irrevocably and fully and unconditionally guaranteed by Willis Group Holdings, Willis Netherlands Holdings B.V., Willis Investment UK Holdings Limited, TA I Limited, TA II Limited, Trinity Acquisition plc, TA III Limited, TA IV Limited, and Willis Group Limited, the Guarantor Companies. On that date and in connection with an internal group reorganisation, TA II Limited, TA III Limited and TA IV Limited transferred their obligations

as guarantors to the other Guarantor Companies. TA II Limited, TA III Limited and TA IV Limited entered member’s voluntary liquidation on December 31, 2010. The assets of these companies were distributed to the other Guarantor Companies, either directly or indirectly, as a final distribution paid prior to their entering member’s voluntary liquidation. These final distributions have been excluded from the 2010 results and cash flows of the Other Guarantors. The final distributions comprise: a $4.3 billion dividend from TA IV Limited to Trinity Acquisition plc; a $5.1 billion distribution from TA III Limited to TA II Limited and a $4.7 billion distribution from TA II Limited to TA I Limited. Since all of the liquidated guarantors were ultimately liquidated into another guarantor, these transactions did not have a material impact on the guarantees of the senior notes and did not require the consent of the noteholders under the applicable indentures.

Willis Group Holdings was incorporated on September 24, 2009 and, as discussed in Note 2, replaced Willis-Bermuda as the ultimate parent company on December 31, 2009. Willis Netherlands Holdings B.V. was incorporated on November 27, 2009.

The debt securities that were issued by Willis North America and guaranteed by the entities described above, and for which the disclosures set forth below relate and are required under applicable SEC rules, were issued under a “shelf” registration statements on Form S-3, including our current June 2009 registration statement (the “Willis Shelf”). The Willis Shelf also covers and contemplates possible issuances of securities by, and guarantees by, other Willis group entities, including Willis Group Holdings. One possible structure originally contemplated by the Willis Shelf was for debt securities issued by Trinity Acquisition plc and guaranteed by certain of its direct and indirect parent entities, but not guaranteed by its direct and indirect subsidiaries, including Willis North America, and the financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2009 included a footnote (Note 25) that corresponded to this possible issuance structure. We have determined that we will not utilize the Willis Shelf to issue debt securities using such a structure, and we therefore have not included a corresponding footnote in these financial statements.

Presented below is condensed consolidating financial information for:

The equity method has been used for investments in subsidiaries in the condensed consolidating balance sheets for the year ended December 31, 2010 of Willis Group Holdings, the Other Guarantors and the Issuer. Investments in subsidiaries in the condensed consolidating balance sheet for Other, represents the cost of investment in subsidiaries recorded in the parent companies of the non-guarantor subsidiaries.

The entities included in the Other Guarantors column for the year ended December 31, 2010 are Willis Netherlands Holdings B.V., Willis Investment UK Holdings Limited, Trinity Acquisition plc, TA I Limited, TA II Limited, TA III Limited, TA IV Limited and Willis Group Limited. See the discussion above describing the liquidation of certain of these entities.

Management’s Report on Internal Control over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rule 13a-15(f) under the Securities Exchange Act of 1934.

Under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting as of December 31, 2010, based on the criteria related to internal control over financial reporting described in Internal Control — Integrated Framework issued by the

Committee of Sponsoring Organizations of the Treadway Commission. Based on our evaluation, management concluded that our internal control over financial reporting was effective as of December 31, 2010.

Our independent registered public accountants, Deloitte LLP, who have audited and reported on our financial statements, have undertaken an assessment of the Company’s internal control over financial reporting. Deloitte’s report is presented below.

February 25, 2011.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of Willis Group Holdings Public Limited Company,

We have audited the internal control over financial reporting of Willis Group Holdings Public Limited Company and subsidiaries (the ‘Company’) as of December 31, 2010, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed by, or under the supervision of, the company’s principal executive and principal financial officers, or persons performing similar functions, and effected by the company’s board of directors, management, and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of the inherent limitations of internal control over financial reporting, including the possibility of collusion or improper management override of controls, material misstatements due to error or fraud may not be prevented or detected on a timely basis. Also, projections of any evaluation of the effectiveness of the internal control over financial reporting to future periods are subject to the risk that the controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2010, based on the criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated financial statements as of and for the year ended December 31, 2010 of the Company and our report dated February 25, 2011 expressed an unqualified opinion on those financial statements.

Deloitte LLP

Changes in Internal Control over Financial Reporting

There has been no change in the Company’s internal controls over financial reporting during the three months ended December 31, 2010 that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.

As discussed in our Form 8-K furnished on February 10, 2011 and in Management’s Discussion & Analysis, we anticipate that we will incur pre-tax charges of approximately $110 million to $130 million, primarily recorded in the first quarter of 2011, in connection with our operational review, certain of which charges will be costs associated with exit or disposal activities under Item 2.05 of Form 8-K. The Board of Directors authorized senior management to implement such plan on February 3, 2011.
