Commercial Mortgage Residual Interests [Abstract] |
Commercial Mortgage Residual Interests | Commercial Mortgage Residual Interests: NNN holds the residual interests (“Residuals”) from seven commercial mortgage securitizations. Each of the Residuals is recorded at fair value based upon an independent valuation. Unrealized gains and losses are reported as other comprehensive income in stockholders' equity and other than temporary losses as a result of a change in the timing, or amount of estimated cash flows are recorded as an other than temporary valuation impairment. Due to the expected timing of future cash flows relating to the Residuals, the independent valuation adjusted certain of the valuation assumptions. The following table summarizes the key assumptions used in determining the value of the Residuals as of:
| September 30, 2013 |  | December 31, 2012
Discount rate (1) | 20% or 25% |  |  | 25 | %
Average life equivalent CPR(2) speeds range | 0.80% to 19.39% CPR |  |  | 0.80% to 24.31% CPR |
Foreclosures: |  |  |
Frequency curve default model | 0.07% - 3.97% range |  |  | 0.09% - 4.49% range |
Loss severity of loans in foreclosure | 20 | % |  | 20 | %
Yield: |  |  |

Prime | Forward curve |  |  | Forward curve |
(1) For September 30, 2013, three of the securitizations have a 20% discount rate and four have a 25% discount rate. (2) Conditional prepayment rate. The following table summarizes the recognition of unrealized gains and/or losses recorded as other comprehensive income as well as other than temporary valuation impairments recorded in the condensed consolidated statements of earnings (dollars in thousands):
