Certain exercisable stock options were excluded from 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 2.0 million at September 30, 2013 and 3.3 million at September 30, 2012. The range of exercise prices related to the excluded exercisable stock options was $19.54 - $40.83 at September 30, 2013 and $15.58 - $40.83 at September 30, 2012.
