[1] The fair values of forward and swap contracts are based on period-end forward rates and reflect the value of the amount that we would pay or receive for the contracts involving the same notional amounts and maturity dates.

[2] We provide a domestic non-qualified deferred compensation plan covering certain employees, which allows for the deferral of compensation for an employee-specified term or until retirement or termination. Amounts deferred can be allocated to various hypothetical investment options. We hold investments to satisfy the future obligations of the plan. Changes in the value of the investment accounts are recognized each period based on the fair value of the underlying investments. Employees making deferrals are entitled to receive distributions of their hypothetical account balances (amounts deferred, together with earnings (losses)).

[3] We estimate the fair value of our long-term debt using discounted cash flow analyses, based on our current incremental borrowing rates for similar types of borrowing arrangements.(4)Contingent consideration obligations arise from prior business acquisitions. The fair values are based on discounted cash flow analyses reflecting the possible achievement of specified performance measures or events and captures the contractual nature of the contingencies, commercial risk, and the time value of money. Contingent consideration obligations are classified in the consolidated balance sheets as accrued expense (short-term) and other liabilities (long-term), as appropriate based on the contractual payment dates.The changes in Level 3 assets and liabilities measured at fair value on a recurring basis at June 30, 2012 are summarized as follows: Contingent ConsiderationBalance at March 31, 2012$6,953Losses33Settlements(9)Foreign currency translation adjustments (1)(422)Balance at June 30, 2012$6,555(1) Reported in other comprehensive income (loss)
