NOTE H — COMMON STOCK AND EARNINGS PER SHARE

Basic earnings per share are based on the weighted-average number of shares outstanding for each period. Shares that have been repurchased and retired during the periods specified below have been included in the calculation of the number of weighted-average shares that are outstanding for the calculation of basic earnings per share based on the time they were outstanding in any period. Diluted earnings per common share are based on shares that are outstanding (computed under basic EPS) and on potentially dilutive shares. Shares that are included in the diluted earnings per share calculations under the treasury stock method include equity awards that are in-the-money but have not yet been exercised.

The following is a reconciliation of the numerator and denominator used to calculate basic earnings per share and diluted earnings per share for the periods indicated:


	Three Months Ended
	April 1,	March 31,
	2017	2018

Net earnings available to common shareholders	$ 21,358	$ 28,946


Weighted average common shares outstanding - basic	24,499	24,074

Dilutive effect of in-the-money equity awards	477	199

Weighted average common shares outstanding - diluted	24,976	24,273


Earnings per common share from net earnings - basic	$ 0.87	$ 1.20

Earnings per common share from net earnings - diluted	$ 0.86	$ 1.19


Equity awards for the following shares were not included in the computation of diluted EPS due to the fact that
their effect would be anti-dilutive:
	Three Months Ended
	April 1,	March 31,
	2017	2018
	2,179	1,802

There were no share repurchases during the three months ended April 1, 2017. During the three months ended March 31, 2018, the Company repurchased and retired 39 shares for $2,943 under the Company’s share repurchase plan. The excess of the repurchase price over par value is allocated between additional paid-in capital and retained earnings on a pro-rata basis. The purchase of shares under this plan reduces the number of shares outstanding in the above calculations.

As of March 31, 2018, the remaining approved repurchase amount under the stock repurchase plan was $47,057. There currently is no expiration date on the remaining approved repurchase amount and no requirement for future share repurchases.
