[1] See Note 10 — Fair Value Disclosures for the determination of the fair value of these instruments.

[2] The swaps have been designated and are accounted for as cash flow hedges of the forecasted interest payments on borrowings. As a result, changes in fair value of the swaps are deferred and are recorded in AOCL, net of tax effect (see Note 6 — Debt for additional information).

[3] The Company has foreign exchange transaction risk since it typically enters into transactions in the normal course of business that are denominated in foreign currencies that differ from the local functional currency. The Company enters into short-term foreign currency forward exchange contracts to offset the economic effects of these foreign currency transaction risks. These contracts are accounted for at fair value with realized and unrealized gains and losses recognized in Other expense, net since the Company does not designate these contracts as hedges for accounting purposes. All of the contracts outstanding at June 30, 2015 matured by the end of July 2015.
