In a sign of deteriorating credit quality, Standard & Poor’s on Tuesday stripped oil giant Exxon Mobil Corp. of its pristine AAA rating, leaving just two U.S. non-financial companies with what is the highest possible rating on their debt.

Microsoft Corp. MSFT, -0.67% and consumer goods giant Johnson & Johnson JNJ, -0.13% are now the only companies to enjoy an AAA rating, the strongest possible vote of confidence in their financial strength and discipline in meeting all of their debt obligations. As recently as 2008, there were six AAA-rated companies, but General Electric Co. GE, -0.13% Pfizer Inc. PFE, -0.03% and Automatic Data Processing ADP, +0.15% have been downgraded since then.
