NEW YORK (Standard&Poor's) Oct. 3, 2013--Standard&Poor's Ratings Services said today that the 'A-2' short-term rating and commercial paper rating on cable TV operator Comcast Corp. remain unchanged following the company's recent upsizing of its commercial paper program to $6.25 billion from $2.25 billion. The company has adequate liquidity, which supports our 'A-2' short-term rating and commercial paper rating under our criteria, in conjunction with the company's maintenance of $6.25 billion in committed revolving credit facilities available through June 2017. Our rating assumes that the company will maintain sufficient availability under these credit facilities to provide 100% coverage of commercial paper issuances outstanding at any given time. Our 'A-' corporate credit rating on Comcast remains unchanged. The
