Cross-currency swap

On September 30, 2010, the Company entered into a cross-currency swap agreement (the “replacement swap agreement”) with JPMorgan Chase Bank and Royal Bank of Scotland PLC (the “counterparties”) to manage its cash flows related to foreign currency exposure for a portion of the Company’s intercompany receivable of a U.S. dollar functional currency subsidiary that is denominated in Euro.

Under the terms of the swap agreement, the Company pays Euros based on a €28.7 million notional value and a fixed rate of 5.00% and receives U.S. dollars based on a notional value of $39.5 million and a fixed rate of 4.635%. The expiration date is December 30, 2016, the date upon which the underlying intercompany debt, to which the swap agreement applies, matures. The swap agreement is designated as a cash flow hedge and therefore the Company recognized an unrealized gain (loss) on the change in fair value, net of tax, within other comprehensive income (loss).
