[1] In March 2001, the Company issued $4.6 billion of long-term debt instruments, primarily to finance the acquisition of Keebler Foods Company. The preceding table reflects the remaining principal amounts outstanding as of year-end 2011 and 2010. The debt securities contain standard events of default and covenants. The Notes due 2011 and the Debentures due 2031 could be redeemed in whole or in part by the Company at any time at prices determined under a formula (but not less than 100% of the principal amount plus unpaid interest to the redemption date). The effective interest rate on the Debentures due 2031, reflecting issuance discount and hedge settlement, was 7.62%. In May 2009, the Company entered into interest rate swaps with notional amounts totaling $400 million, which effectively converted a portion of the Notes due 2011 from a fixed rate to a floating rate obligation for the remainder of the ten-year term. These derivative instruments were designated as fair value hedges of the debt obligation. The Company redeemed $72 million of the Notes due 2011 in December 2007, an additional $482 million in December 2009, and the remainder in April 2011. The Company incurred $35 million of interest expense and $3 million of accelerated losses on interest rate swaps previously recorded in accumulated other comprehensive income in connection with the 2009 redemption.

[2] On December 8, 2010, the Company issued $1.0 billion of ten-year 4.0% fixed rate U.S. Dollar Notes, using net proceeds from these Notes for incremental pension and postretirement benefit plan contributions and to retire a portion of its commercial paper. The effective interest rate on these Notes, reflecting issuance discount and hedge settlement, was 3.42%. 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.

[3] On March 6, 2008, the Company issued $750 million of five-year 4.25% fixed rate U.S. Dollar Notes, using the 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 1.733% at December 31, 2011. 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 $22 million at December 31, 2011 will be amortized to interest expense over the remaining term of the Notes.

[4] On May 18, 2009, the Company issued $750 million of seven-year 4.45% fixed rate U.S. Dollar Notes, using net proceeds from these Notes to retire a portion of its commercial paper. The effective interest rate as of December 31, 2011 on these Notes, reflecting issuance discount, hedge settlement and interest rate swaps, was 3.89%. 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 February 2011, the Company entered into interest rate swaps with notional amounts totaling $200 million, which effectively converted a portion of these Notes from a fixed rate to a floating rate obligation for the remainder of the seven-year term. These derivative instruments were designated as fair value hedges of the debt obligation. The fair value adjustment for the interest rate swaps was $14 million, and was recorded as an increase in the hedged debt balance at December 31, 2011.

[5] In December 2007, the Company issued $750 million of five-year 5.125% fixed rate U.S. Dollar Notes, using the proceeds from these Notes to replace 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 3.632% at December 31, 2011. 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 May 2009, the Company entered into interest rate swaps with notional amounts totaling $750 million, which effectively converted these Notes from a fixed rate to a floating rate obligation. These derivative instruments were designated as fair value hedges of the debt obligation. In August 2011, the Company terminated the interest rate swaps. The unamortized gain of $10 million at December 31, 2011 will be amortized to interest expense over the remaining term of the Notes.

[6] On November 14, 2011, the Company issued $500 million of five-year 1.875% fixed rate U.S. Dollar Notes, using net proceeds from these Notes for general corporate purposes including repayment of a portion of its commercial paper.

The customary covenants also contain a change of control provision.

The effective interest rate as of December 31, 2011 on these Notes, reflecting issuance discount, hedge settlement and interest rate swaps, was 2.31%.
