NY -- Standard&Poor's CreditWire 10/1/97 -- Standard&Poor's today assigned its preliminary single-'A' rating to E.W. Scripps Co.'s $500 million debt securities filed under a Rule 415 shelf registration. In addition, Standard&Poor's affirmed its single-'A' corporate credit and senior unsecured debt ratings and 'A-1' commercial paper rating on the company. The ratings outlook is stable. Ratings are supported by Scripps' diversified media properties and geographic mixes, strong operating margins, and healthy cash flow generation.
