Fair Value Measurements
5. Fair Value Measurements
The Company determines fair value based on the fair value hierarchy, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value assumes that the transaction to sell the asset or transfer the liability occurs in the principal or most advantageous market for the asset or liability and establishes that the fair value of an asset or liability shall be determined based on the assumptions that market participants would use in pricing the asset or liability. The classification of a financial asset or liability within the hierarchy is based upon the lowest level input that is significant to the fair value measurement. The fair value hierarchy prioritizes the inputs into three levels that may be used to measure fair value:
Level 1:     Inputs are unadjusted quoted prices in active markets for identical assets or liabilities.
Level 2:    Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
Level 3:    Inputs are unobservable based on the Company’s own assumptions used to measure assets and liabilities at fair value. The inputs require significant management judgment or estimation.
The fair value of our Level 1 financial instruments, such as money market funds which are traded in active markets, is based on quoted market prices for identical instruments. The fair value of our Level 2 financial instruments such as commercial paper, corporate debt and U.S. government securities are obtained from an independent pricing service, which may use inputs other than quoted prices that are directly or indirectly observable in the market, including readily available pricing sources for the identical underlying security that may not be actively traded. Our marketable securities are held by custodians who obtain investment prices from a third-party pricing provider that incorporates standard inputs in various asset price models.
