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 30, 2019 and December 29, 2018, were available-for-sale and reported at fair value based on the estimated or quoted market prices as of the balance sheet date.

Realized gains and losses on sale of securities are recorded in other income (expense), net, in the Company’s condensed consolidated statement of operations. For the three months ended March 30, 2019 and March 31, 2018, net realized gains and losses were not material.

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 months ended March 30, 2019 and March 31, 2018 were not material, and no marketable securities had other than temporary impairment.

All marketable securities as of March 30, 2019 and December 29, 2018 had maturity dates of less than 36 months.
