Fair Value Disclosures [Abstract] |
Fair Value Measurements | FAIR VALUE MEASUREMENTS: The Company’s fair value measurements are classified and disclosed in one of the following three categories: Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities; Level 2: Quoted prices in markets that are not active, or inputs which are observable, either directly or indirectly, for substantially the full term of the asset or liability; Level 3: Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported by little or no market activity). The following table summarizes the valuation of the Company’s investments and financial instruments that are measured at fair value on a recurring basis:

The Company's cash equivalents consist primarily of highly liquid investments in money market funds and term deposits with maturity periods of three months or less. Restricted cash relates primarily to temporary restrictions caused by the timing of lockbox collections under the Company's borrowing arrangements and the timing of payments under vendor agreements. The carrying values of the cash equivalents approximate fair value since they are near their maturity. Investments in trading and available-for-sale securities consist of equity securities and are recorded at fair value based on quoted market prices. The fair values of forward exchange contracts are measured based on the foreign currency spot and forward rates quoted by the banks or foreign currency dealers. Fair values of interest rate swaps are measured using standard valuation models using inputs that are readily available in public markets, or can be derived from observable market transactions, including LIBOR spot and forward rates. The effect of nonperformance risk on the fair value of derivative instruments was not material as of November 30, 2015 and November 30, 2014. The acquisition-related contingent consideration liability represents the future potential earn-out payments relating to an acquisition. The fair value of the contingent consideration liability is based on the Company’s probability assessment of the established profitability measures during the earn-out period ranging from one year to three years from the date of the acquisition. The carrying values of held-to-maturity securities, accounts receivable, accounts payable and short-term debt approximate fair value due to their short maturities and interest rates which are variable in nature. The carrying value of the Company's term loans approximate their fair value since they bear interest rates that are similar to existing market rates. During fiscal years 2015 and 2014, there were no transfers between the fair value measurement category levels.
