Commenting on its fugures (Company Results, page 5), AT&T Co says that Equipment sales are not what we would like, but they tend to lag economic upturns and that it still expects sales to improve later in the year; AT&T said second quarter operating profit for its NCR unit was $98m, up from $46m in the first quarter, when the unit acquired Teradata Corp, but the figures are not comparable with 1991, since NCR results now include AT&T’s former computer business, Teradata and sales to other AT&T units; telecommunications services revenues rose 2.2% to $9,850m, the company said.
