Our marketable securities consist of investments in marketable equity and debt securities. We classify all of our marketable securities as available-for-sale. Our marketable equity securities are carried at fair value using quoted market prices, primarily Level 1 inputs as defined by ASC Topic 820, Fair Value Measurements and Disclosures, with any unrealized gains or losses on the securities

recognized in other income, net on our Condensed Consolidated Statements of Income. The fair value of our marketable debt securities is generally determined using Level 2 inputs because although these securities are traded in many cases, the market is not active and the quarter-end valuation is generally based on the last trade of the quarter, which may be several days prior to quarter end. We accumulate unrealized gains and losses on marketable debt securities as part of accumulated other comprehensive income (loss), net of related deferred income taxes. See Note 17.
