We net derivative assets and liabilities, including cash collateral, when a legally enforceable master netting arrangement exists between the counterparty to a derivative contract and us. At October 1, 2011, and October 2, 2010, we had posted $113 million and $35 million of cash collateral and held $0 and $3 million cash collateral with various counterparties, respectively.
