Earnings Per Share (EPS) [Abstract]

Earnings Per Share (EPS)

3.     EARNINGS PER SHARE (EPS)

Basic EPS is calculated using the weighted average number of common shares outstanding during the period. Diluted EPS is calculated using the weighted average number of common shares outstanding during the period plus shares issuable upon the assumed exercise of dilutive common share options and vesting of performance-accelerated restricted shares (restricted shares) by using the treasury stock method. The number of shares used in the calculation of earnings per share for each period presented is as follows (in thousands):

	Three Months Ended March 31,		Six Months Ended March 31,
	2012	2011	2012	2011
Weighted Average Shares Outstanding - Basic	26,706	26,583	26,689	26,562
Dilutive Options and Restricted Shares	279	300	251	285
Adjusted Shares - Diluted	26,985	26,883	26,940	26,847

Options to purchase 124,654 shares of common stock at prices ranging from $35.69 - $45.20 and options to purchase 255,462 shares of common stock at prices ranging from $37.54 - $54.88 were outstanding during the three-month periods ended March 31, 2012 and 2011, respectively, but were not included in the computation of diluted EPS because the options' exercise prices were greater than the average market price of the common shares. The options expire at various periods through 2014. Approximately 232,000 and 210,000 restricted shares were excluded from the computation of diluted EPS for the three-month periods ended March 31, 2012 and 2011, respectively, based upon the application of the treasury stock method.
