The description of inputs used in the fair value measurement of liabilities. Inputs are the assumptions that market participants would use when pricing the liability, including assumptions about risk such as the risk inherent in a particular valuation technique used to measure fair value (such as a pricing model) and the risk inherent in the inputs to the valuation technique.
