 Derivative Financial Instruments

We utilize derivative financial instruments to manage the economic impact of fluctuations in currency exchange rates on those transactions that are denominated in currencies other than our functional currency, which is the U.S. dollar.  We enter into currency forward contracts to manage these economic risks.  We account for all derivatives on the balance sheet within other assets or accounts payable measured at fair value, and changes in fair values are recognized in earnings unless specific hedge accounting criteria are met for cash flow or net investment hedges. As of January 26, 2013 and April 28, 2012, we had not designated any of our derivative instruments as accounting hedges, and thus we recorded the changes in fair value in other income (expense), net.

The foreign currency exchange contracts in aggregated notional amounts in place to exchange United States Dollars at January 26, 2013 and April 28, 2012 were as follows:
