Fitch Affirms 1 and Downgrades 2 RMBS Classes from SASCO ARC 2001-BC5.

NEW YORK -- Fitch Ratings has taken rating actions on the following Structured Asset Security Corp. Amortizing Residential Collateral Trust (SASCO ARC) Issue:

Series ARC 2001-BC5

--Class A affirmed at 'AAA';

--Class M-1 downgraded to 'A-' from 'AA-';

--Class M-2 downgraded to 'BB+' from 'BBB+'.

The mortgage loans initially consisted of approximately 16.03% fixed and 83.97% adjustable-rate, fully amortizing and balloon, first and second lien conventional residential mortgage loans which do not exceed the Freddie Mac maximum original principal balance limitation. The loans were extended to sub-prime borrowers and are secured by first and second liens, primarily on one to four-family residential properties. Substantially all of the Mortgage Loans were acquired by either Lehman Capital, A Division of Lehman Brothers Holdings Inc. or Lehman Brothers Bank, FSB (and thereafter, assigned by the Bank to Lehman Capital) from Finance America, LLC or First Franklin Financial Corporation. The loans are master serviced by Wells Fargo (rated 'RMS1' by Fitch) and serviced by Countrywide and Ocwen Federal Bank (rated 'RPS1' and 'RPS2' respectively by Fitch).

As of the September 2006 distribution date, the transaction is seasoned 61 months and the pool factor (current mortgage loan principal outstanding as a percentage of the initial pool) is approximately 6%. The cumulative loss to date incurred on the pool as a percentage of the initial balance is 2%.

The affirmation reflects a stable relationship between credit enhancement (CE) and future loss expectations and affects approximately $20.1 million of outstanding certificates.

The downgrades affecting approximately $9.8 million of outstanding certificates reflect deterioration in the relationship between CE and expected losses due to higher-than-expected serious delinquency and an OC amount below its target amount. Approximately 44% of the pool is more than 60 days delinquent (including loans in Bankruptcy, Foreclosure and REO). The OC amount is currently $1,251,856, below its target amount of $1,448,111. In three of the past 6 months, the excess spread has not been sufficient to cover the monthly losses incurred.

Fitch will continue to closely monitor these transactions. Further information regarding current delinquency, loss, and credit enhancement statistics is available on the Fitch Ratings website at www.fitchratings.com.
