12. Net Income Per Share Data

Basic net income per common share is calculated by dividing net income by the weighted average number of common shares outstanding during the period. Diluted net income per common share is computed by dividing net income by the weighted average number of common and common equivalent shares outstanding during the period. The Company’s potentially dilutive common shares are those that result from dilutive common stock options, non-vested stock relating to restricted stock awards, restricted stock units, deferred stock units and performance shares.

The following table sets forth the denominator for the computation of basic and diluted net income per share:

	Three Months Ended				Nine Months Ended
	June 30,				June 30,
(Dollars in thousands)	2016		2015		2016		2015
Net income available to common shareholders	$	4,003	$	3,924	$	7,341	$	10,590
Basic weighted average shares outstanding		12,995		13,002		12,969		13,057
Dilutive effect of outstanding stock options, non-vested restricted stock, restricted stock units, deferred stock units and performance shares		289		277		234		267
Diluted weighted average shares outstanding		13,284		13,279		13,203		13,324

The calculation of weighted average diluted shares outstanding excludes outstanding stock options associated with the right to purchase 0.3 million shares of common stock for each of the three months ended June 30, 2016 and 2015, respectively, and 0.2 million and 0.3 million for the nine months ended June 30, 2016 and June 30, 2015, respectively, as their inclusion would have had an antidilutive effect on diluted net income per share.

On November 5, 2014, the Company’s Board of Directors authorized it to repurchase up to $30.0 million of the Company’s outstanding common stock in open-market purchases, privately negotiated transactions, block trades, accelerated share repurchase transactions, tender offers or by any combination of such methods. The authorization has no fixed expiration date. The Company used $20.0 million of this authorization for the share repurchase discussed below.

On November 11, 2014, the Company entered into an accelerated share repurchase (“ASR”) program with Wells Fargo Bank, National Association. In connection with this agreement, the Company made a $20.0 million payment to the bank and immediately received an initial delivery of 758,143 shares of its common stock with a fair value of $16.0 million as of the purchase date. Effective as of the date of the initial share purchase, the transaction was accounted for as a share retirement, resulting in a reduction of common stock of less than $0.1 million, additional paid-in capital of $2.5 million and retained earnings of $13.5 million. The remaining $4.0 million of the Company’s payment was also reported as a reduction in retained earnings. The specific number of shares that the Company ultimately purchased under the ASR agreement was based on the volume weighted average price (“VWAP”) of the Company’s common stock during the purchase period, less an agreed upon discount. In the aggregate, the Company purchased 847,864 shares under the ASR program for an average price of $23.59 per share. Based on the facts associated with the agreement, the forward contract was indexed to the Company’s common stock and met the U.S. GAAP requirements to be classified as permanent equity as of July 8, 2015, the date the ASR program was completed.

On November 6, 2015, the Company’s Board of Directors authorized the repurchase of up to $20.0 million of the Company’s outstanding common stock in addition to the $10.0 million authorization which remains available from the November 5, 2014 authorization.
