Credit Loss Component Of OTTI On Debt Securities Recognized In Earnings
The following table presents a progression of the credit loss component of OTTI on debt and equity securities recognized in earnings during the nine months ended September 30, 2013 and for the year ended December 31, 2012 (in thousands).  The credit loss component represents the difference between the present value of expected future cash flows and the amortized cost basis of the security.  The credit component of OTTI recognized in earnings during a period is presented in two parts based upon whether the credit impairment in the current period is the first time the security was credit impaired (initial credit impairment) or if there is additional credit impairment on a security that was credit impaired in previous periods.

The differences noted consist of unrealized gains (losses) recorded at September 30, 2013 and noncredit other-than-temporary impairment losses recorded subsequent to April 1, 2009 that have not been reclassified as credit losses.
(2)
Performing collateral is defined as total collateral minus all collateral that has been called, is currently deferring, or currently in default. This model for this security assumes that all collateral that is currently deferring will default with a zero recovery rate. The underlying issuers can cure, thus this bond could recover at a higher percentage upon default than zero.
(3)
Performing collateral is defined as total collateral minus all collateral that has been called, is currently deferring, or currently in default.  The model for this security assumes that one of the banks that is currently deferring will cure.  If additional underlying issuers cure, this bond could recover at a higher percentage.
(4)
Excess subordination is defined as the additional defaults/deferrals necessary in the next reporting period to deplete the entire credit enhancement (excess interest and over-collateralization) beneath our tranche within each pool to the point that would cause a "break in yield." This amount assumes that all currently performing collateral continues to perform. A break in yield means that our security would not be expected to receive all the contractual cash flows (principal and interest) by maturity. The "percent of current performing collateral" is the ratio of the "excess subordination amount" to current performing collateral—a higher percent means there is more excess subordination to absorb additional defaults/deferrals, and the better our security is protected from loss.
(5)
No other-than-temporary impairment losses were recognized during the nine months ended September 30, 2013.  Other-than-temporary impairment losses of $11,000 were recognized during the year ended December 31, 2012.
(6)
No other-than-temporary impairment losses were recognized during the nine months ended September 30, 2013.  Other-than-temporary impairment losses of $565,000 were recognized during the year ended December 31, 2012.
Amortized Cost And Estimated Fair Value Of Debt Securities By Contractual Maturity
The amortized cost and estimated fair value of debt securities at September 30, 2013, by contractual maturity, are shown in the following table (in thousands).  Expected maturities will differ from contractual maturities because the issuers of the securities may have the right to prepay obligations without prepayment penalties.  Mortgage-backed securities have been allocated to their respective maturity groupings based on their contractual maturity.
