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. The carrying value of the cash equivalents approximates the 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.
The acquisition-related contingent consideration liability represents the future potential earn-out payments relating to the acquisitions in the GBS segment. The fair values of the contingent consideration liabilities are based on the Company’s probability assessment of the established profitability measures during the periods ranging from one year to three years from the date of the acquisitions. During the three and six months ended May 31, 2013, the fair value of the contingent consideration liability was remeasured and the resulting decrease of $142 and $447, respectively, were recorded as a benefit to “Selling, general and administrative expenses” in the Consolidated Statements of Operations. The change in the fair value was due to updated estimates of expected revenue and gross profit related to the achievement of established earn-out targets. The remaining change in the carrying value of the liability is due to the translation effect of foreign currencies.
The carrying value of held-to-maturity securities, accounts receivable, accounts payable and short-term debt, approximate fair value due to their short maturities and the 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. The convertible debt had a carrying value of $143,750 and $141,436 as of May 31, 2013 and November 30, 2012, respectively. The fair value of the convertible debt was $167,735 as of November 30, 2012, which is based on the closing price of the convertible debt traded in a limited trading market and is categorized as level 2 in the fair value measurement category levels. On April 16, 2013, the Company called all of the outstanding convertible debt, as a result, the financial instrument was no longer traded. The Company gave notice to the converting noteholders that it will settle all of the convertible debt in cash. The final settlement of amounts due upon conversion of the convertible debt will be made during the three months ending August 31, 2013.
During the three and six months ended May 31, 2013, there were no transfers between the fair value measurement category levels.
