Certain exercisable stock options were excluded in the computations of diluted EPS because the exercise price of these options was greater than the average period market prices. The number of stock options outstanding, which were not included in the calculation of diluted EPS, was 4.1 million at September 30, 2011 and 4.8 million at September 30, 2010. The ranges of exercise prices related to the excluded exercisable stock options were $15.56 - $40.83 at September 30, 2011 and $10.08 - $40.83 at September 30, 2010.

As part of the 2009 Settlement and Commercial Agreement, we issued to GM five year warrants, which entitled GM to purchase 4.1 million shares of AAM's common stock at an exercise price of $2.76 per share. In the first quarter of 2011, GM exercised these warrants. In accordance with the cashless exercise option available in the agreement, we issued 3.3 million net shares of common stock to GM.
