Business description of ATLANTIC-UNION-BANKSHARES-CORPORATION from last 10-k form

Level 1   Valuation is based on quoted prices in active markets for identical assets and liabilities.
Level 2   Valuation is based on observable inputs including quoted prices in active markets for similar assets and liabilities, quoted prices for identical or similar assets and liabilities in less active markets, and model-based valuation techniques for which significant assumptions can be derived primarily from or corroborated by observable data in the markets.
Level 3   Valuation is based on model-based techniques that use one or more significant inputs or assumptions that are unobservable in the market. These unobservable inputs reflect the Company’s assumptions about what market participants would use and information that is reasonably available under the circumstances without undue cost and effort.
