did you own AT&T common stock (T) as of the close of business on April 5, 2022, the record date for distribution of shares of SpinCo as part of the WarnerMedia/Discovery transaction? If so, you received an ownership interest in Warner Bros. Discovery (WBD) following the distribution.
If you sold any AT&T share after this date, your basis is adjusted.
AT&T provides some calculators and worksheets for you.
