Investments In Securities Held To Maturity

Note 4 - Investment in Securities Held to Maturity

As of September 30, 2017, investment in securities held to maturity primarily consisted of corporate fixed income securities and commercial paper. The Company did not have investments prior to the first quarter of 2017. The Company classifies all investments as held to maturity as these investments are short term, highly liquid investments which we intend to hold to maturity. Held to maturity securities are recorded at cost and gains and losses are only recognized as the sale or redemption of the securities is realized. Realized gains and losses are included in non-operating other income (expense) on the condensed statement of operations and are derived using the specific identification method for determining the cost of the securities sold. During the three and nine months ended September 30, 2017, the Company had a minimal amount of net realized gain (loss) on investments recorded. Interest and dividends on investments held to maturity are included in interest and other income, net, in the condensed statements of operations.
