Fair Value Measurements	6. Fair Value Measurements The fair value hierarchy has three levels based on the inputs used to determine fair value, which are as follows: Level 1 — Unadjusted quoted prices available in active markets for the identical assets or liabilities at the measurement date. Level 2 — Unadjusted quoted prices in active markets for similar assets or liabilities, or unadjusted quoted prices for identical or similar assets or liabilities in markets that are not active, or inputs other than quoted prices that are observable for the asset or liability. Level 3 — Unobservable inputs that cannot be corroborated by observable market data and reflect the use of significant management judgment. These values are generally determined using pricing models for which the assumptions utilize management’s estimates of market participant assumptions. The fair value hierarchy requires the use of observable market data when available. In instances where the inputs used to measure fair value fall into different levels of the fair value hierarchy, the fair value measurement has been determined based on the lowest level input significant to the fair value measurement in its entirety. Our assessment of the significance of a particular item to the fair value measurement in its entirety requires judgment, including the consideration of inputs specific to the asset or liability. Financial instruments include cash, accounts receivable, other current assets, accounts payable, short-term debt and other current liabilities. The carrying amounts of these financial instruments approximated fair value at June 30, 2013 and December 31, 2012 due to their short-term maturities. The fair value of the Term Loan, Revolver and swing loans at June 30, 2013 and December 31, 2012 approximated the carrying amount as the interest rate is based upon floating short-term interest rates (Level 2). At June 30, 2013 and December 31, 2012, the fair value of the Notes (Level 2) approximated the carrying amount.
