The Company’s 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, 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 the Company’s available-for-sale securities were primarily a result of unfavorable changes in interest rates subsequent to the initial purchase of these securities. As of October 31, 2012, the Company owned 20 securities that were in an unrealized loss position. The Company does not intend nor expect to need to sell these securities before recovering the associated unrealized losses. It expects to recover the full carrying value of these securities. As a result, no portion of the unrealized losses at October 31, 2012 is deemed to be other-than-temporary and the unrealized losses are not deemed to be credit losses. No available-for-sale securities have been in an unrealized loss position for 12 months or more. When evaluating the investments for other-than-temporary impairment, the Company reviews 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 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 months ended October 31, 2012, the Company did not recognize any impairment charges.
