[1] This swap has been designated, and is accounted for, as a cash flow hedge of the forecasted interest payments on borrowings (see Note 7 — Debt). As a result, changes in fair value of this swap are deferred and are recorded in OCI, net of tax effect.

[2] See Note 11 — Fair Value Disclosures for the determination of the fair value of these instruments.

[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. The majority of the outstanding contracts at June 30, 2013 matured by the end of July 2013.
