AirTouch Communications Inc has not done any hurt to its credit standing with its plan to throw in its US cellular lot with US West Inc: Standard & Poor’s Corp it affirmed the triple-B-plus credit assessment rating of the company and US West Inc’s A-plus senior debt and A-1-plus commercial paper rates are unchanged. The ventures include a joint management and ownership agreement covering both companies’ existing cellular businesses and a joint venture being formed to bid on Personal Communications Services; AirTouch’s credit quality is not affected by the two proposed wireless alliances because initially there will be no transfer of cellular assets, and the bidding plans are in line with the ratings agency’s prior expectations. US West’s ratings are unchanged but were placed on review with negative implications on the news that it plans to acquire those two cable television properties in the Atlanta market, the agency said.
