May 22 () - Standard & Poor's Ratings Services said today that it assigned its 'A-' issue-level rating to Dallas-based AT&T Inc.'s proposed senior unsecured notes (undetermined amount but denominated in Pound Sterling) due 2044. We expect the company to use net proceeds for general corporate purposes, and we do not expect this transaction to materially impact key credit measures for more than a temporary period. The 'A-' long-term corporate credit rating on AT&T remains unchanged, as do the 'A-2' short-term rating and the stable rating outlook. The ratings on AT&T continue to reflect an overall "strong" business risk profile and a financial risk profile which Standard & Poor's considers "intermediate" (as defined in our criteria), recognizing the company's substantial free operating cash flow generation and adjusted leverage of about 2.6x as of March 31, 2012. Our business risk assessment is based on the combined impact of a strong and growing wireless business, with a wireline segment that we view as having a weaker, but still satisfactory, business risk profile.
