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 December 26, 2015 and December 27, 2014, were available-for-sale and reported at fair value based on the estimated or quoted market prices as of the balance sheet date.  Gross realized gain and losses on sale of securities are recorded in other income, net, in our statement of operations.  Net realized gain and losses for fiscal 2015, 2014, and 2013 was $0.2 million, $0.2 million and $0.2 million, respectively.

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 fiscal years ended December 26, 2015, and December 27, 2014 were insignificant and no marketable securities had other than temporary impairment. All marketable securities as of December 26, 2015 and December 27, 2014, had maturity dates of less than two years and were not invested in foreign entities.
