The difference between basic EPS and diluted EPS is due to potentially dilutive common shares resulting from NEDSP, the ESPP and the LTIP.

The following table outlines the calculation for earnings per share (EPS):

		Weighted-average number of common shares outstanding		235,840,558		235,847,596		235,048,347
	Per Share Amounts
		Net income per share – basic	$	1.37	$	0.69	$	0.97
Diluted EPS

	Denominator(1)
		Weighted-average number of shares outstanding before dilution		235,840,558		235,847,596		235,048,347

	Diluted Weighted Average Number of Shares			237,883,881		237,767,071		236,294,812
	Per Share Amounts
		Net income per share - diluted	$	1.35	$	0.69	$	0.96
(1)		The denominator does not include stock equivalents for options issued under the non-qualified stock option plan due to conversion prices
		being higher than market prices for all periods. Under this plan, an additional 297,803, 390,095 and 563,624 shares for 2012, 2011
		and 2010, respectively, would be included in each of these periods if the conditions for conversion were met.
