(11) Earnings per Share

Stock Dividend On July 1, 2018, the Company paid a special stock dividend of 4% to common shareholders of record at the close of business on June 15, 2018. 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)	2019		2018
Basic earnings per share:
Net income available to shareholders	$	4,666	$	2,090
Average shares outstanding		6,034,843		6,028,708
Basic earnings per share	$	0.77	$	0.35
Diluted earnings per share:
Net income available to shareholders	$	4,666	$	2,090
Average shares outstanding		6,034,843		6,028,708
Effect of dilutive stock options		—		5,949
Average shares outstanding including dilutive stock options		6,034,843		6,034,657
Diluted earnings per share	$	0.77		0.35

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. There were no outstanding stock options for any of the three months ended March 31, 2019 and 2018, respectively, that were omitted from the computation of diluted earnings per share as a result of being considered anti-dilutive.
