[1] In March 2008, the Company issued $750 million of five-year 4.25% fixed rate U.S. Dollar Notes, using net proceeds from these Notes to retire a portion of its U.S. commercial paper. The effective interest rate on these Notes, reflecting issuance discount, hedge settlement and interest rate swaps was 1.73% at December 29, 2012. The Notes contain customary covenants that limit the ability of the Company and its restricted subsidiaries (as defined) to incur certain liens or enter into certain sale and lease-back transactions. The customary covenants also contain a change of control provision. In conjunction with this debt issuance, the Company entered into interest rate swaps with notional amounts totaling $750 million, which effectively converted this debt from a fixed rate to a floating rate obligation. These derivative instruments were designated as fair value hedges of the debt obligation. During 2011, the Company transferred a portion of the interest rate swaps to another counterparty and subsequently terminated all the interest rate swaps. The resulting unamortized gain of $4 million and $22 million, at December 29, 2012 and December 31, 2011, respectively, will be amortized to interest expense over the remaining term of the Notes.
