3. Investments and Restricted Deposits
Short-term and long-term investments and restricted deposits by investment type consist of the following:
The Company's investments are classified as available-for-sale with the exception of life insurance contracts and certain cost method and equity method investments. The Company's investment policies are designed to provide liquidity, preserve capital and maximize total return on invested assets with the focus on high credit quality securities. The Company limits the size of investment in any single issuer other than U.S. treasury securities and obligations of U.S. government corporations and agencies. As of September 30, 2011, 36% of the Company's investments in securities recorded at fair value that carry a rating by Moody's or S&P were rated AAA, 77% were rated AA- or higher, and 99% were rated A- or higher. At September 30, 2011, the Company held certificates of deposit, life insurance contracts and cost and equity method invesments which did not carry a credit rating.
The fair value of available-for-sale investments with gross unrealized losses by investment type and length of time that individual securities have been in a continuous unrealized loss position were as follows:
As of September 30, 2011, the gross unrealized losses were generated from 25 positions out of a total of 410 positions. The decline in fair value of fixed income securities is a result of movement in interest rates subsequent to the purchase of the security.
For each security in an unrealized loss position, the Company assesses whether it intends to sell the security or if it is more likely than not the Company will be required to sell the security before recovery of the amortized cost basis for reasons such as liquidity, contractual or regulatory purposes. If the security meets this criterion, the decline in fair value is other-than-temporary and is recorded in earnings. The Company does not intend to sell these securities prior to maturity and it is not likely that the Company will be required to sell these securities prior to maturity; therefore, there is no indication of other than temporary impairment for these securities.
The contractual maturities of short-term and long-term investments and restricted deposits are as follows:
Actual maturities may differ from contractual maturities due to call or prepayment options. Asset backed securities are included in the one year through five years category, while equity securities and life insurance contracts are included in the five years through ten years category. The Company has an option to redeem at amortized cost substantially all of the securities included in the greater than ten years category listed above.
Realized gains and losses are determined on the basis of specific identification or a first-in, first-out methodology, if specific identification is not practicable. The Company's gross recorded realized gains and losses on investments were as follows:
Realized gains in the nine months ended September 30, 2010 included a net realized gain of $2,472 related to sales of fixed income investments and also included realized gains of $3,287 representing a distribution from the Reserve Primary fund in excess of our adjusted basis.
The Company continuously monitors investments for other-than-temporary impairment. Certain investments have experienced a decline in fair value due to changes in credit quality, market interest rates and/or general economic conditions. The Company recognizes an impairment loss for cost and equity method investments when evidence demonstrates that it is other-than-temporarily impaired. Evidence of a loss in value that is other than temporary may include the absence of an ability to recover the carrying amount of the investment or the inability of the investee to sustain a level of earnings that would justify the carrying amount of the investment.
During the quarter ended September 30, 2010, the Company determined it had an other-than-temporary impairment of a cost method investment in a start-up company that provides software to automate the clinical, administrative, and technical components of care management programs. As a result, the Company recorded an impairment charge of $5,531, including $3,531 of convertible promissory notes. The impairment charge is included in investment and other income for the quarter.
Investment amortization of $7,545 and $8,380 was recorded in the nine months ended September 30, 2011 and 2010, respectively.
Tabular disclosure of investments in certain debt and equity securities (and certain other trading assets) which include all debt and equity securities (other than those equity securities accounted for under the equity or cost methods of accounting) with readily determinable fair values. Other trading assets include assets that are carried on the balance sheet at fair value and held for trading purposes. A debt security represents a creditor relationship with an enterprise that is in the form of a security. Debt securities include, among other items, US Treasury securities, US government securities, municipal securities, corporate bonds, convertible debt, commercial paper, and all securitized debt instruments. An equity security represents an ownership interest in an enterprise or the right to acquire or dispose of an ownership interest in an enterprise at fixed or determinable prices. Equity securities include, among other things, common stock, certain preferred stock, warrant rights, call options, and put options, but do not include convertible debt. An entity may opt to provide the reader with additional narrative text to better understand the nature of investments in debt and equity securities (and other trading assets).
