Derivative Instruments and Hedging Activities
Staples uses interest rate swap agreements, foreign currency swap and foreign currency forward agreements to offset certain operational and balance sheet exposures related to changes in interest or foreign exchange rates.  These agreements are entered into to support transactions made in the normal course of business and accordingly are not speculative in nature.  These derivatives qualify for hedge accounting treatment as the derivatives have been highly effective in offsetting changes in fair value of the hedged items.
 All derivatives are recorded at fair value and the changes in fair value are immediately included in earnings if the derivatives do not qualify as effective hedges. If a derivative is designated as a fair value hedge, then changes in the fair value of the derivative are offset against the changes in the fair value of the underlying hedged item in earnings.  If a derivative is designated as a cash flow hedge, then the effective portion of the changes in the fair value of the derivative is recognized as a component of accumulated other comprehensive income (loss) until the underlying hedged item is recognized in earnings or the forecasted transaction is no longer probable of occurring. If a derivative or a nonderivative financial instrument is designated as a hedge of the Company's net investment in a foreign subsidiary, then changes in the fair value of the financial instrument are recognized as a component of accumulated other comprehensive income (loss) to offset a portion of the change in the translated value of the net investment being hedged, until the investment is sold or liquidated. The Company formally documents all hedging relationships for all derivative and nonderivative hedges and the underlying hedged items, as well as its risk management objectives and strategies for undertaking the hedge transactions.  There are no amounts excluded from the assessment of hedge effectiveness.
The Company classifies the fair value of all derivative contracts and the fair value of its hedged firm commitments as either current or long-term depending on whether the maturity date of the derivative contract is within or beyond one year from the balance sheet date. The cash flows from derivatives treated as hedges are classified in the Company's consolidated statement of cash flows in the same category as the item being hedged.
 Interest Rate Swaps:   In January 2003, Staples entered into interest rate swaps for an aggregate notional amount of $325 million. These swaps were designed as a fair value hedge and designed to convert the October 2012 Notes into a variable rate obligation. At January 29, 2011, the interest rate swap agreement had a fair value gain of $23.0 million, which was included in other assets. In September 2011, the Company terminated the $325 million interest rate swaps, realizing a gain of $12.4 million, which is being amortized over the remaining term of the October 2012 Notes. No amounts were included in the consolidated statement of income for 2011, 2010 or 2009 related to ineffectiveness associated with this fair value hedge.
  In March 2010, Staples entered into interest rate swaps for an aggregate notional amount of $750 million. These swaps were designated as a fair value hedge and designed to convert half of the aggregate principal amount of the January 2014 Notes into a variable rate obligation.  At January 29, 2011 the interest rate swap agreement had a fair value gain of $21.4 million which was included in other assets. In September 2011, the Company terminated the $750 million interest rate swaps, realizing a gain of $30.3 million, which is being amortized over the remaining term of the January 2014 Notes. No amounts were included in the consolidated statement of income for 2011 or 2010 related to the ineffectiveness associated with this fair value hedge.
 In connection with Staples' acquisition of Corporate Express, the Company assumed interest rate swaps designed to convert Corporate Express' variable rate credit facilities into fixed rate obligations.  In May 2011, the Company repaid the outstanding balance on these variable rate credit facilities and terminated the related interest rate swap agreements. As a result, $0.3 million was recognized as a loss related to the termination of these interest rate swap agreements.
