[1] The fair value of the Company's FX Contracts was measured based on observable market transactions of spot and forward rates at December 31, 2012 and 2011. (See Note 12, "Financial Instruments.")

[2] Holders of the Preferred Stock were entitled to receive upon a change of control transaction (as defined in the certificate of designation of the Preferred Stock) through October 8, 2012, a pro rata portion of the equity value received in such transaction, capped at an amount that would provide aggregate cash payments of $12.00 per share over the term of the Preferred Stock (the calculation of such payments being the "Change of Control Amount"). As of December 31, 2011, the fair value of the Change of Control Amount of the Preferred Stock, which was deemed to be a Level 3 liability was based on the Company's assessment of the likelihood of the occurrence of specified change of control transactions within three years of the consummation of the 2009 Exchange Offer. As of October 8, 2012, holders of the Preferred Stock are no longer entitled to receive the Change of Control Amount as three years have passed without the occurrence of a change of control transaction. Accordingly, the Company reversed the liability for the Change of Control Amount of $0.2 million, which was included as income in miscellaneous, net in the Company's Consolidated Statements of Income and Comprehensive Income for the year ended December 31, 2012 (see Note 10, "Long-Term Debt and Redeemable Preferred Stock").
