3. | MARKETABLE EQUITY SECURITIES
The Company accounts for its marketable securities in accordance with ASC Topic 320, Investments-Debt and Equity Securities . ASC Topic 320 requires companies to classify their investments as trading, available-for-sale or held-to-maturity. The Company’s investments in marketable securities are classified as either trading or available-for-sale and consist of equity securities. Management determines the appropriate classification of these securities at the time of purchase and re-evaluates such designation as of each balance sheet date. The cost of securities sold is based on the specific identification method and interest and dividends on securities are included in non-operating income (loss). Marketable equity securities classified as available-for-sale are carried at fair value, with the unrealized gains and losses, net of tax, included as a component of accumulated other comprehensive income (loss) in stockholders’ equity. Realized gains and losses, declines in value judged to be other-than-temporary on available-for-sale securities, and increases or decreases in value on trading securities, if any, are included in the determination of net income. A quarterly evaluation is performed in order to judge whether declines in value below cost should be considered temporary and when losses are deemed to be other-than-temporary. Several factors are considered in this evaluation process including the severity and duration of the decline in value, the financial condition and near-term outlook for the specific issuer and the Company’s ability to hold the securities. For the years ended December 31, 2017, 2016 and 2015, the evaluation resulted in impairment charges of approximately $42,000, $709,000 and $833,000, respectively, being reported in the Company’s non-operating income (loss) in its statements of operations. The following table sets forth cost, market value and unrealized gain on equity securities classified as available-for- sale as of December 31, 2017 and 2016. The Company had no securities classified as trading securities as of December 31, 2017 or December 31, 2016.
