Two tranches from two alternative-A mortgage-backed securities deals issued by RBSGC have been downgraded by Moody's Investors Service. Class B-1 of RBSGC Mortgage Loan Trust 2007-A was downgraded from Aa2 to A2, and class 1B1 of RBSGC Mortgage Loan Trust 2007-B was downgraded from Aa2 to A2. The downgrades were based, in general, on higher-than-expected rates of delinquency, foreclosure, and real estate owned in the underlying collateral relative to credit enhancement levels, the rating agency said. The collateral consists primarily of first-lien, fixed-rate, alt-A mortgage loans.

Three tranches from one alternative-A transaction issued by Prime Mortgage Trust have been downgraded by Moody's Investors Service. The downgrades were as follows: Prime Mortgage Trust 2006-CL1, class M-4, from Baa1 to Baa3; class M-5, from Baa2 to Ba3; and class M-6, from Ba1 to B3. Class M-6 remains on review for possible further downgrade. The downgrades were based, in general, on higher-than-expected rates of delinquency, foreclosure, and real estate owned in the underlying collateral relative to credit enhancement levels, the rating agency said. The collateral consists primarily of first-lien, fixed -rate, alt-A mortgage loans.

Five classes of mortgage pass-through certificates issued by Merrill Lynch Mortgage Investors Merrill Lynch Credit Corp. have been downgraded by Fitch Ratings. The downgrades were as follows: series 2003-C, class B-4, from BBB-plus to BB, and class B-5, from BB-plus to CC/DR3; and series 2004-G, class B-3, from BBB to B, class B-4, from BB-plus to CC/DR4, and class B-5, from B-plus to C/DR6. Fitch also affirmed the ratings on seven other classes in the two deals. The downgrades were attributed to "current trends in the relationship between serious delinquency and credit enhancement." The collateral consists of adjustable-rate prime mortgage loans.

Six classes of notes from Sharps CDO I, a static cash flow collateralized debt obligations backed partly by alternative-A residential mortgage-backed securities, have been downgraded by Fitch Ratings. The downgrades were as follows: class A-1, from AAA to A-minus; class A-2, from AAA to A-minus; class B, from AA-plus to CC; class C, from A-plus to C; class D, from BBB to C; and class E, from BB to E. The downgraded classes were all removed from Rating Watch Negative. Fitch attributed the downgrades to "significant collateral deterioration" in the portfolio's alt-A RMBS. Approximately 63% of the portfolio has been downgraded since the transaction closed in December 2006, the rating agency said.

Fifty additional classes of subprime mortgage-backed securities were downgraded by Fitch Ratings on May 2. Fitch also affirmed the ratings on classes with outstanding balances of more than $1.3 billion. The securities affected by the latest downgrades were: 22 classes from eight issues by Merrill Lynch Mortgage Investors; 15 classes from 10 issues by Asset Backed Funding Corp.; eight classes from three issues by Specialty Underwriting and Residential Finance; and five classes from four issues by Countrywide (CWABS).

Fifty-seven certificates from 11 transactions issued by Structured Asset Securities Corp. and backed by second-lien loans have been downgraded by Moody's Investors Service. Moody's also placed 19 classes of certificates on review for possible downgrade. The downgrades were attributed to the fact that credit enhancement levels, including excess spread and subordination, were too low in view of projected losses, Moody's said. "The actions take into account the continued and worsening performance of transactions backed by closed-end-second collateral," the rating agency said, adding that "substantial pool losses" in recent months have eroded the credit enhancement available to the mezzanine and senior certificates.

Fitch Ratings and Standard & Poor's Ratings Services downgraded the ratings of Residential Capital LLC, Minneapolis, following ResCap's announcement of an exchange offer for approximately $14 billion of unsecured bonds. Fitch downgraded the company's issuer default rating from BB-minus to C and its senior debt from B-plus to C, while S&P downgraded ResCap's long-term corporate credit rating from CCC-plus to CC. Both rating agencies said they were likely to lower their ratings further, to default status, upon the execution of the exchange offer. "ResCap's announced debt exchange offer is part of a plan to address the company's capital structure in light of current and expected future market conditions, by lengthening debt maturities and providing security to first-lien creditors," Fitch said. ".... At the completion of the exchange, Fitch would assign a post-default IDR and new issue-level ratings solely reflecting a prospective view of ResCap and its new capital structure." The rating agency said it "envisions" that the new IDR would fall in the single-B category. S&P said a successful exchange by ResCap "would extend debt maturities, providing needed relief, but the action illustrates the gravity of the company's financial position."
