Starting with the first event after you acquired your shares, click at the appropriate step. Your cost basis will be automatically calculated.
Click Here if you owned AT&T shares before the divestiture of Southwestern Bell and other regional telephone operating companies Jan. 1, 1984.
$ per AT&T share x 0.949 = $ New Cost Basis
(The Southwestern Bell allocation factor at divestiture was 0.0949 which must be multiplied by 10 because shareholders received one-tenth share in each of the regional companies for each share of old AT&T.)
