Oct 28 (Reuters) - AT&T Inc on Monday unveiled a three-year strategic plan that included adding two new board members, selling off up to $10 billion worth of non-core businesses next year and paying off all its debt from the purchase of Time Warner, bowing to pressure from activist investor Elliott Management.

The plan "benefited from our engagement with our owners, including Elliott Management," Stephenson said in a statement.
In a letter to shareholders supporting the plan, Elliott Management said AT&T would evaluate all potential CEO candidates and separate the role of Chairman and CEO.
"We commend AT&T for the positive steps announced today, which will create substantial and enduring shareholder value at one of America's greatest companies," Elliott said in a statement.
A source familiar with the matter said Monday that Elliott is supportive of the board member AT&T is expected to nominate this year at the next board meeting.
