The contractual maturities of cash equivalents and short-term investments at June 30, 2015, and December 31, 2014, were less than one year. There were no long-term investments at June 30, 2015 and December 31, 2014.

The Company typically invests in highly rated securities and its policy generally limits the amount of credit exposure to any one issuer. When evaluating the investments for other-than-temporary impairment, the Company reviews such factors as the length of time and extent to which fair value has been below cost basis, the financial condition of the issuer, 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 amortized cost basis. During the three and six months ended June 30, 2015 and 2014, the Company did not recognize any impairment charges on outstanding investments. As of June 30, 2015, the Company does not consider any of its investments to be other-than-temporarily impaired.
