Senior MBS Portfolio Reaches $1 Billion Mark

MFA announced today that it has made substantial progress in acquiring additional senior most tranches of non-Agency RMBS (“Senior MBS”) to complement its existing portfolio of Agency MBS.  Utilizing net proceeds from its July 29, 2009 common stock offering, as of September 10, 2009, MFA had a total of $1.04 billion market value of Senior MBS, consisting of approximately $840 million owned through its wholly-owned subsidiary, MFResidential Assets I, LLC, and approximately $200 million of legacy Senior MBS owned directly.

Stewart Zimmerman, MFA’s Chairman of the Board and CEO, said, “We are pleased with our progress in investing the proceeds of our July equity offering.  MFA’s strategy of focusing on investment opportunities within the residential MBS arena continues to deliver value for stockholders.  Our book value per share of common stock has increased to $7.25 as of August 31, 2009 from $6.99 as of June 30, 2009 and has increased 37% from $5.29 as of December 31, 2008.”

William Gorin, MFA’s President and CFO, said, “We continue to utilize our cash position to acquire additional discounted Senior MBS.  While we are in the process of investing the equity offering proceeds and reinvesting portfolio run-off, there has been an increase in our low-yielding cash position.  This temporary increase in our cash position will be reflected in our third quarter earnings which, based on current conditions, we project to be in the range of $0.25 - $0.26.  At the midpoint, this EPS represents a 14% annualized return on $7.25 per share of equity.”
