1. We note your response to comment 1. Please consider revising your disclosure in future filings to specifically address any known trends (i.e. lower CPR), the drivers of such and your expectation of whether or not the trend will continue. Please also be more specific as to how you evaluate historical prepayment rates in determining your projected long-term CPR percentages and how you evaluate the sustainability of current monetary and fiscal policy and other factors as they relate to your assessment of the sustainability of a lower CPR for purposes of your projection.

Response:

The Company respectfully acknowledges the Staff’s comment, and in connection with future reports to be filed by the Company pursuant to the Securities Exchange Act of 1934, as amended (the “Exchange Act”), the Company will specifically address any known trends (i.e. lower CPR), the drivers of such and its expectation of whether or not the trend will continue. The Company will also specifically address how it evaluates historical prepayment rates in determining its projected long-term CPR percentages and how it evaluates the sustainability of current monetary and fiscal policy and other factors as they relate to the Company’s assessment of the sustainability of a lower CPR for purposes of its projection.

Response:

The Company respectfully acknowledges the Staff’s comment, and in connection with future Exchange Act reports, the Company will provide a more in depth discussion of the factors (mentioned in its prior response letter to the Staff) that led to its decision to sell Agency MBS at an accelerated rate during 2013 as compared to the previous two years.

The Company also acknowledges that:
