American Telephone & Telegraph confirmed that it is re-evaluating aspects of its relationship with Ing. C. Olivetti & Co., the Italian partner that builds its personal computer line. AT&T; Chairman Robert E. Allen said the company may curtail purchases of Olivetti personal computers and may seek another supplier, according to a report in the Wall Street Journal. Allen also said the company plans to take “direct” management control of its foreign operations. Olivetti currently sells AT&T; minicomputers in Europe. Allen said the Olivetti review was prompted in part by changes in currency exchange rates and the two companies’ product portfolios, according to the Journal story. AT&T; owns 22.3% of Olivetti’s stock.
