Gross unrealized losses decreased slightly during the first half of 2011 primarily due to the impact of lower interest rates. We have reviewed our securities for which there is an unrealized loss in accordance with our accounting policies for other-than-temporary impairment (“OTTI”). As a result of our reviews, OTTI of less than $1 million was recognized in earnings on certain debt securities during the three and six months ended June 30, 2011 and 2010. During the six months ended June 30, 2011, we recognized a $1 million loss in other comprehensive income relating to the non-credit component of OTTI as compared to a $1 million recovery related to OTTI previously recognized in accumulated other comprehensive income during the year-ago period. We do not consider any other securities to be other-than-temporarily impaired because we expect to recover the entire amortized cost basis of the securities and we neither intend to nor expect to be required to sell the securities prior to recovery, even if that equates to holding securities until their individual maturities. However, additional other-than-temporary impairments may occur in future periods if the credit quality of the securities deteriorates.
 
On-Going Assessment for Other-Than-Temporary Impairment  On a quarterly basis, we perform an assessment to determine whether there have been any events or economic circumstances to indicate that a security with an unrealized loss has suffered other-than-temporary impairment. A debt security is considered impaired if the fair value is less than its amortized cost basis at the reporting date. If impaired, we then assess whether the unrealized loss is other-than-temporary.
 
An unrealized loss is generally deemed to be other-than-temporary and a credit loss is deemed to exist if the present value of the expected future cash flows is less than the amortized cost basis of the debt security. As a result, the credit loss component of an other-than-temporary impairment write-down for debt securities is recorded in earnings while the remaining portion of the impairment loss is recognized net of tax in other comprehensive income (loss) provided we do not intend to sell the underlying debt security and it is more-likely-than-not that we would not have to sell the debt security prior to recovery.
 
For all our debt securities, as of the reporting date we do not have the intention to sell these securities and believe we will not be required to sell these securities for contractual, regulatory or liquidity reasons.
 
We consider the following factors in determining whether a credit loss exists and the period over which the debt security is expected to recover:
 
  •  The length of time and the extent to which the fair value has been less than the amortized cost basis;
 
  •  The level of credit enhancement provided by the structure which includes, but is not limited to, credit subordination positions, overcollateralization, protective triggers and financial guarantees provided by monoline wraps;
 
  •  Changes in the near term prospects of the issuer or underlying collateral of a security, such as changes in default rates, loss severities given default and significant changes in prepayment assumptions;
 
  •  The level of excess cash flows generated from the underlying collateral supporting the principal and interest payments of the debt securities; and
 
  •  Any adverse change to the credit conditions of the issuer or the security such as credit downgrades by the rating agencies.
 
At June 30, 2011, approximately 93 percent of our corporate debt securities are rated A- or better and approximately 62 percent of our asset-backed securities, which totaled $50 million are rated “AAA.” At December 31, 2010, approximately 92 percent of our corporate debt securities were rated A- or better and approximately 66 percent of our asset-backed securities, which totaled $60 million were rated “AAA.” Although OTTI of less than $1 million was recorded in earnings during the six months ended June 30, 2011 and 2010, additional other-than-temporary impairments may occur in future periods.
 
Proceeds from the sale, call or redemption of available-for-sale investments totaled $339 million and $449 million during the three and six months ended June 30, 2011, respectively, compared to $37 million and $111 million during the three and six months ended June 30, 2010, respectively. We realized gross gains of $12 million and $15 million during the three and six months ended June 30, 2011, respectively, compared to $1 million and $4 million during the three and six months ended June 30, 2010, respectively. We realized gross losses of less than $1 million during both the six months ended June 30, 2011 and 2010.
