Available-for-sale marketable securities, readily convertible to cash, with maturity dates of 90 days or less are classified as cash equivalents, while those with maturity dates greater than 90 days are classified as marketable securities within short-term assets. All marketable securities as of March 29, 2014 and December 28, 2013 were available-for-sale and reported at fair value based on the estimated or quoted market prices as of the balance sheet date. Unrealized gains or losses, net of tax effect, are recorded in accumulated other comprehensive income (loss) within stockholders' equity. Both the gross unrealized gains and gross unrealized losses for the three month periods ended March 29, 2014 and March 30, 2013 were insignificant and no marketable securities had other than temporary impairment. All marketable securities as of March 29, 2014 and December 28, 2013, had maturity dates of less than two years and were not invested in foreign entities.
