Our investment policy requires investments to be investment grade, primarily rated “A1” by Standard & Poor’s or “P1” by Moody’s or better for short-term investments and rated “A” by Standard & Poor’s or “A2” by Moody’s or better for long-term investments, with the objective of minimizing the potential risk of principal loss. In addition, the investment policy limits the amount of credit exposure to any one issuer.
 
The unrealized losses on our available-for-sale securities as of September 30, 2015 were primarily a result of unfavorable changes in interest rates subsequent to the initial purchase of these securities. As of September 30, 2015, we owned 77 securities that were in an unrealized loss position. Based on our cash flow needs, we may be required to sell a portion of these securities prior to maturity. However, we expect to recover the full carrying value of these securities. As a result, no portion of the unrealized losses at September 30, 2015 is deemed to be other-than-temporary and the unrealized losses are not deemed to be credit losses. When evaluating the investments for other-than-temporary impairment, we review factors such as the length of time and extent to which fair value has been below cost basis, the financial condition of the issuer and any changes thereto, and our intent to sell, or whether it is more likely than not we will be required to sell, the investment before recovery of the investment’s amortized cost basis. During the three and nine months ended September 30, 2015, we did not recognize any impairment charges. During the three and nine months ended September 30, 2015, proceeds from the sale of available-for-sale securities were $37.7 million and $41.3 million. We did not recognize a realized gain or loss in connection with these sales.
