We have classified our marketable securities as available-for-sale. Accordingly, we record them at fair value and account for net unrealized gains and losses as part of accumulated other comprehensive income. We report realized gains and losses on the sale of our marketable securities in earnings, computed using the specific identification method. During the three months ended March27, 2010, we realized $0.3million in gains and $0.1million in losses on our marketable securities. During the three months ended March28, 2009, we realized an immaterial amount in gains and did not realize any losses on our marketable securities. See Note 10. Fair Value Measurement, to our condensed consolidated financial statements for information about the fair value measurement of our marketable securities.
All of our available-for-sale marketable securities are subject to a periodic impairment review. We consider a marketable debt security to be impaired when its fair value is less than its carrying cost, in which case we would further review the investment to determine whether it is other-than-temporarily impaired. When we evaluate an investment for other-than-temporary impairment, we review factors such as the length of time and extent to which fair value has been below cost basis, the financial condition of the issuer and any changes thereto, our intent to sell, and whether it is more likely than not we will be required to sell the investment before we have recovered its cost basis. If an investment is other-than-temporarily impaired, we write it down through earnings to its impaired value and establish that as a new cost basis for the investment. We did not identify any of our marketable securities as other-than-temporarily impaired at March27, 2010 and December26, 2009.
The following table summarizes the unrealized gains and losses related to our investments in marketable securities designated as available-for-sale, by major security type as of March27, 2010 and December26, 2009 (in thousands):
