[1] The Company’s derivative financial instruments are subject to master netting arrangements that allow for the offset of asset and liabilities in the event of default or early termination of the contract. The Company elects to record the gross assets and liabilities of its derivative financial instruments in the consolidated balance sheets. If the derivative financial instruments had been netted in the consolidated balance sheets, the asset and liability positions each would have been reduced by $130 million and $142 million at June 28, 2015 and December 28, 2014, respectively. No material amounts of collateral were received or posted on the Company’s derivative assets and liabilities as of June 28, 2015.
