The complicated corporate history of AT&T causes many shareholders to throw up their hands in frustration at the thought of calculating their cost basis.
Some investors even decide to hold their AT&T shares (and all the spinoffs) rather than deal with the accounting nightmare.
If you own or owned any of the following securities and don't remember where you got them, your holdings may have originated from ownership of shares of the original American Telephone & Telegraph Co (not to be confused with the current AT&T Inc. which is the former SBC Communications.)
Airtouch Communications A T & T Broadband A T & T Corp. A T & T Inc. A T & T Wireless Services, Inc. Ameritech (became SBC then AT&T) Bell Atlantic (became Verizon) BellSouth Corp. Comcast Corp. Fairpoint Communications (Verizon spinoff)
Idearc (Verizon spinoff) Lucent Technologies MediaOne Group NCR Corp. Nynex (became Verizon) Pacific Telesis SBC Communications Inc. (became AT&T Inc.) Southern New England Telecommunications Southwestern Bell (became SBC Comm.) Teradata Corp (NCR spinoff) US West (became Qwest)
