Verizon (NYSE:VZ) announced that its board has authorized the corporation to repurchase up to 100M shares of its common stock. The board also determined that no additional shares may be acquired under a previously approved program to repurchase up to 100M shares. Under the previous program, which was due to end February 28, approval remained to purchase approximately 60M shares. The authorization to repurchase shares terminates when the aggregate number of shares repurchased reaches 100M or at the close of business on February 28, 2014, whichever is earlier.
