The Company may sell certain of its marketable securities, available-for-sale prior to their stated maturities for strategic reasons including, but not limited to, anticipation of credit deterioration, duration management and when a security no longer meets the criteria of the Company’s investment policy. During the nine months ended September 30, 2016, the Company sold one security, which no longer met the requirements of its investment policy for a loss of $152,000.

As of September 30, 2016, the Company considers the declines in market value of its marketable securities, available-for-sale to be temporary in nature and does not consider any of its investments other-than-temporarily impaired. The Company typically invests in highly-rated securities, and its investment policy generally limits the amount of credit exposure to any one issuer. The policy generally requires investments to be investment grade, with the primary objective of minimizing the potential risk of principal loss and matching long-term liabilities. When evaluating an investment for other-than-temporary impairment the Company reviews factors such as the length of time and extent to which fair value has been below its cost basis, the financial condition of the issuer and any changes thereto, changes in market interest rates and the Company’s intent to sell, or whether it is more likely than not it will be required to sell the investment before recovery of the investment’s cost basis.
