(11)	Earnings per Share

Stock Dividend On July 1, 2017, the Company paid a special stock dividend of 4% to common shareholders of record at the close of business on June 15, 2017. For all periods presented, share information, including basic and diluted earnings per share, has been adjusted retroactively to reflect this change.

Basic earnings per share is computed by dividing income available to shareholders by the weighted average number of shares outstanding during the year. Diluted earnings per share gives effect to all dilutive potential shares that were outstanding during the year.

Presented below is a summary of the components used to calculate basic and diluted earnings per common share, which have been restated for all stock dividends:

	Three Months Ended March 31,
(dollars in thousands, except per share data)	2018		2017
Basic earnings per share:
Net income available to shareholders	$	2,090	$	2,100
Basic earnings per share	$	0.36	$	0.36
Diluted earnings per share:
Net income available to shareholders	$	2,090	$	2,100
Average shares outstanding		5,797,134		5,839,850
Effect of dilutive stock options		5,720		4,916
Average shares outstanding including dilutive stock options		5,802,854		5,844,766
Diluted earnings per share	$	0.36		0.36

Under the treasury stock method, outstanding stock options are dilutive when the average market price of the Company’s common stock, when combined with the effect of any unamortized compensation expense, exceeds the option price during the period, except when the Company has a loss from continuing operations available to shareholders. In addition, proceeds from the assumed exercise of dilutive options along with the related tax benefit are assumed to be used to repurchase common shares at the average market price of such stock during the period.

Options to purchase 0 and 21,621 shares during the three months ended March 31, 2018 and 2017, respectively, were not included in the respective computations of diluted earnings per share because the exercise price of the option, when combined with the effect of the unamortized compensation expense, was greater than the average market price of the common shares and were considered anti-dilutive.

Repurchase Program On August 6, 2015, the Board of Directors authorized a share repurchase plan (the plan) to purchase through open market transactions up to $2.0 million market value of the Company’s common stock. On August 8, 2017, the Board authorized the repurchase of an additional $1.5 million market value of the Company’s common stock. As of March 31, 2018, the Company had repurchased a total of 92,509 shares of common stock pursuant to the plan at an average price of $17.80 per share, including 5,468 shares of common stock repurchased pursuant to the plan during the three months ended March 31, 2018 at an average price of $20.51 per share. At March 31, 2018, approximately $1.8 million remained available for the purchase of shares under the plan. The current plan expires September 8, 2018 unless renewed.
