AT&T to take $7.9 billion charge

AT&T Inc. said its fourth-quarter results will include a pretax loss of $7.9 billion to account for changes in its pension and retiree benefit plans.

The results will also include a $2.1 billion noncash charge because certain copper assets are no longer needed as customer demand declines for older voice and data products, the Dallas- based company said in a regulatory filing today.

AT&T shares fell as much as 1.3 percent to $33.37 after U.S. markets closed. The company is scheduled to report earnings results on Jan. 27
