Description: The paper explores developments through 2006 in the application of market-consistent concepts to the measurement of fair values of liabilities for financial reporting purposes. A set of criteria is presented that should be useful in the evaluation of proposed fair value measurement approaches where inputs based on prices observed in an active market with reliable transaction prices are not available. Based on these criteria, one approach is examined that might serve as a basis for the fair value measurement of the liability of life insurance contracts and other financial instruments issued by insurers.
