Wal-Mart (WMT -0.18%) announced today during its annual shareholder meeting that its board has approved a $15 billion share repurchase program.

This new authorization is old hat for Wal-Mart. The corporation passed a similar program in June 2011 and, as of June 6, had just $712 million remaining on that. The company credits its strong cash flow as the primary push behind its repurchase program. Wal-Mart also made mention of its newly increased (to the tune of 18%) dividend as another means for returning capital to its shareholders.
