Statement on FSA's U.S. Sub-Prime RMBS Exposure

March 7, 2007

FSA's total insured net par exposure to the U.S. sub-prime residential mortgage market was $4.9 billion at December 31, 2006, representing 1.3% of FSA's total net par outstanding of $376.5 billion. The underlying internal credit ratings of FSA's sub-prime RMBS portfolio were Triple-A 93.1%, Double-A 1.2%, Single-A 1.1%, Triple-B 3.1% and non-investment grade 1.5% at December 31, 2006, with the non-investment grade exposure concentrated in a handful of very seasoned legacy transactions.

Recent market focus has been on sub-prime originations in 2006 and, to some extent, 2005. FSA's vintage years 2005 and 2006 RMBS sub-prime originations represent $1.3 billion of net par outstanding and the underlying ratings on these transactions were Triple-A 89.1%, with the balance rated Triple-B.

In the sub-prime RMBS sector, FSA's top five servicers account for 67.6% of servicing in this sector.

Top Five Servicers Servicer Ratings S&P / Moody's / Fitch
Ameriquest Strong, Stable/SQ2+/RPS2+
Ocwen Strong, Watch Negative/SQ2-/RPS2
Countrywide Strong, Stable/SQ1/RPS1
SPS Average, Positive/SQ2-/RPS2
Washington Mutual Above Average, Stable/SQ2/RPS2+

FSA exposure to sub-prime RMBS through its CDO sector is less than 0.02% of FSA's total net par outstanding, and almost all of this exposure is to transactions with Super Triple-A underlying credit quality.

As indicated by the ratings above, outside of the handful of legacy exposures, FSA's sub-prime RMBS portfolio is currently performing well, with significant first-loss protection embedded in each individual transaction.
