[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 $237.4 million, $68.9 million and $15.4 million at December 29, 2013, April 28, 2013 and April 29, 2012. No material amounts of collateral were received or posted on the Company’s derivative assets and liabilities as at December 29, 2013.
