Fair value accounting uses current market values as the basis for recognizing certain assets and liabilities. Fair value is estimated as the price an asset could be sold for or a liability settled under current market conditions in an orderly transaction between market participants. There are three approaches to determining fair value - the market approach uses prices from actual market transactions, the income approach discounts estimated future cash flows, and the cost approach estimates replacement cost. Determining fair value involves three levels ranging from quoted active market prices to unobservable inputs.
