[1] During the quarter-ended March 29, 2015 and June 29, 2014, the market value of the Company's Common Stock was greater than or equal to 130% of the 2041 Note conversion price for 20 or more trading days of the 30 consecutive trading days preceding the quarter end. As a result, the 2041 Notes are convertible at the option of the holder. The carrying amount of the 2041 Notes was classified in current liabilities and the excess of the amount of cash payable, if converted, over the carrying amount of the 2041 Notes was classified as temporary equity on the Company's Consolidated Balance Sheets as of March 29, 2015 and June 29, 2014. Upon closure of a conversion period, all 2041 Notes not converted will be reclassified back to noncurrent liabilities and the temporary equity will be reclassified to permanent equity.
