At June 30, 2011, our debt securities with other-than-temporary impairment in which only the amount of loss related to credit was recognized in earnings consisted solely of residential mortgage-backed securities issued by nongovernment-sponsored entities. We utilize third party vendors to estimate the portion of loss attributable to credit using a discounted cash flow models. The vendors estimate cash flows of the underlying collateral of each mortgage-backed security using models that incorporate their best estimates of current key assumptions, such as default rates, loss severity and prepayment rates.

Assumptions utilized vary widely from security to security, and are influenced by such factors as underlying loan interest rates, geographical location of underlying borrowers, collateral type and other borrower characteristics. Specific such assumptions utilized by our vendors in their valuation of our other-than-temporarily impaired residential mortgage-backed securities issued by nongovernment-sponsored entities were as follows at June 30, 2011:

	Weighted	Range
	Average	Minimum	Maximum
Constant voluntary prepayment rates	9.7%	4.7%	12.1%
Constant default rates	7.1%	3.6%	7.5%
Loss severities	49.1%	40.0%	52.0%

Our vendors performing these valuations also analyze the structure of each mortgage-backed instrument in order to determine how the estimated cash flows of the underlying collateral will be distributed to each security issued from the structure. Expected principal and interest cash flows on the impaired debt securities are discounted predominantly using unobservable discount rates which the vendors assume that market participants would utilize in pricing the specific security. Based on the discounted expected cash flows derived from our vendor's models, we expect to recover the remaining unrealized losses on residential mortgage-backed securities issued by nongovernment sponsored entities.

Provided below is a summary of securities available for sale which were in an unrealized loss position at June 30, 2011 and December 31, 2010, including debt securities for which a portion of other-than-temporary impairment has been recognized in other comprehensive income.

We held 84 available for sale securities, including debt securities with other-than-temporary impairment in which a portion of the impairment remains in other comprehensive income, having an unrealized loss at June 30, 2011. We do not intend to sell these securities, and it is more likely than not that we will not be required to sell these securities before recovery of their amortized cost bases. We believe that this decline in value is primarily attributable to the lack of market liquidity and to changes in market interest rates and not due to credit quality. Accordingly, no additional other-than-temporary impairment charge to earnings is warranted at this time.

At June 30, 2011, we had $1.5 million in total unrealized losses related to residential mortgage-backed securities issued by nongovernment sponsored entities. We monitor the performance of the mortgages underlying these bonds. Although there has been some deterioration in their collateral performance, we primarily hold the senior tranches of each issue which provides protection against defaults. We attribute the unrealized loss on these mortgage-backed securities held largely to the current absence of liquidity in the markets for such securities. The mortgages in these asset pools have been made to borrowers with strong credit history and significant equity invested in their homes. Nonetheless, further weakening of economic fundamentals coupled with significant increases in unemployment and substantial deterioration in the value of high end residential properties could extend distress to this borrower population. This could increase default rates and put additional pressure on property values. Should these conditions occur, the value of these securities could decline further and result in the recognition of additional other-than-temporary impairment charges recognized in earnings.
