Dillard's Department Stores Inc. (DDS) had its ratings lowered by Standard & Poor's because of weak consumer spending. S&P cut its corporate credit rating on Dillard's to B+ from BB-. The outlook is stable. "The rating change reflects our belief that the company will be more challenged than previously expected by the current weak economic environment in the U.S., and that credit metrics will deteriorate more than we had originally projected as a result of a deepening spending pull-back by consumers," said Diane Shand, an S&P credit analyst, in a statement.

General Motors Corp. (GM) had its ratings lowered by Standard & Poor's to CCC+ from B- because of cash loss, and had its ratings put on review for a possible downgrade by Fitch after the ailing automaker posted a $2.5 billion loss earlier in the day.

Genworth Financial Inc. (GNW) had its long-term counterparty credit rating lowered to A- from A by Standard & Poor's. S&P also revised its outlook on Genworth's insurance subsidiaries to negative from stable and affirmed the companies' AA- counterparty credit and financial strength ratings. "The GNW downgrade reflects its increased funding needs to meet debt maturities in 2009, reduced fixed-charge coverage, and contraction in diversified cash flows," said S&P credit analyst Kevin Ahern.

Las Vegas Sands Corp. (LVS) said it appointed Kenneth Kay as the company's chief financial officer. The appointment is effective Dec. 1. Kay comes to Sands from CB Richard Ellis Group Inc., where he has served as chief financial officer since 2002.

MBIA Inc. (MBI) said it disagrees with Moody's methodology on capital modeling for mortgage-related losses after the ratings agency lowered the insurance financial strength of its subsidiary MBIA Insurance to Baa1 from A2. "We disagree with Moody's approach to capital modeling for mortgage-related losses, particularly its 'stress on stress' methodology. Nonetheless, the downgrade has very little direct impact on MBIA," said Chief Executive Jay Brown in a statement. Moody's Investors Service downgraded the insurance financial strength rating of MBIA Insurance Corp. and supported insurance companies to Baa1 from A2. Moody's also lowered MBIA Inc.'s debt ratings to non-investment grade rating of Ba1 from Baa2.

Whole Foods Markets Inc. (WFMI) had its corporate credit rating lowered to BB- from BB by Standard & Poor's. "The downgrade reflects our expectation that profitability and credit metrics will most likely be unchanged in the next year," said Charles Pinson-Rose, an S&P credit analyst. "Currently, we expect the company to be effectively cash flow neutral in 2009 but in a situation where sales at the company's existing stores declined sharply, the company would be cash flow negative and now has the excess liquidity," he added. The outlook is stable.
