Marketable Securities
Marketable Securities
The Company invests in marketable securities and classifies them as available-for-sale. The Company records these securities at fair value. Marketable securities reported as current assets represent investments that mature within one year from the balance sheet date. Long-term marketable securities represent investments with maturity dates greater than one year from the balance sheet date. At the time that the maturity dates of these investments become one year or less, the securities are reclassified to current assets. Unrealized gains and losses are excluded from earnings and reported in a separate component of stockholders’ equity until the security is sold or matures. At the time of sale, any gains or losses, calculated by the specific identification method, will be recognized as a component of operating results.
The following is a summary of marketable securities (included in short and long-term marketable securities in the Consolidated Balance Sheets), including accrued interest receivable, as of September 30, 2013 and 2012 (in thousands):
