We compute the effect of dilutive securities using the treasury stock method and average market prices during the period. We determine dilution based on earnings.

Pursuant to the applicable accounting guidance for calculating earnings per share, we have not included the following stock options and SARs in our calculation of diluted earnings per share because the exercise prices were greater than the average market prices for the applicable periods:

(a) for the 2013first quarter, 0.4 million options and SARs; and

(b) for the 2012 first quarter, 1.0 million options and SARs.
