Fair Value Measurements

Note 15. Fair Value Measurements

        Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date.

(a)    Fair Value Hierarchy

        The accounting guidance for fair value measurement requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The standard establishes a fair value hierarchy based on the level of independent, objective evidence surrounding the inputs used to measure fair value. A financial instrument's categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The fair value hierarchy is as follows:

• Level 1    applies to assets or liabilities for which there are quoted prices in active markets for identical assets or liabilities.

  Level 2    applies to assets or liabilities for which there are inputs other than quoted prices that are observable for the asset or liability, such as quoted prices for similar assets or liabilities in active markets; quoted prices for identical assets or liabilities in markets with insufficient volume or infrequent transactions (less active markets); or model-derived valuations in which significant inputs are observable or can be derived principally from, or corroborated by, observable market data.

  Level 3    applies to assets or liabilities for which there are unobservable inputs to the valuation methodology that are significant to the measurement of the fair value of the assets or liabilities.

(b)    Assets Measured at Fair Value on a Recurring Basis

        The Company's money market funds are included in cash and cash equivalents in the Consolidated Balance Sheets, and are considered a level 1 investment as they are valued at quoted market prices in active markets.

        The following table sets forth Company's assets which are measured at fair value on a recurring basis by level within the fair value hierarchy.

(c)    Other Financial Instruments

        The carrying amounts reflected in the consolidated balance sheets for cash and cash equivalents (which are comprised primarily of deposit and overnight sweep accounts), accounts receivable, prepaid expenses and other current and non-current assets, accounts payable and accrued expenses approximate fair value due to their short-term maturities.
