NOTE 15 Earnings Per Share

Beginning in the third quarter of 2019, the Company elected to prospectively use the two-class method in calculating earnings per share due to the restricted stock awards and restricted stock units qualifying as participating securities. Under the two-class method, earnings available to common shareholders for the period are allocated between common shareholders and participating securities according to dividends declared (or accumulated) and participating rights in undistributed earnings. Average shares of common stock for diluted net income per common share include shares to be issued upon the vesting of restricted stock awards and restricted stock units granted under the Company's share-based compensation plans.

The calculation of basic and diluted earnings per share using the two-class method for the three months ending March 31, 2020 is presented below:


	Three months ended
	March 31,
(dollars and shares in thousands, except per share data)	2020
Net income	$	5,363
Dividends and undistributed earnings allocated to participating securities		82
Net income available to common shareholders	$	5,281
Weighted-average common shares outstanding for basic earnings per share		17,070
Dilutive effect of stock-based awards		335
Weighted-average common shares outstanding for diluted earnings per share		17,405
Earnings per common share:
Basic earnings per common share	$	0.31
Diluted earnings per common share	$	0.30

For the three months ended March 31, 2019, the basic and diluted earnings per share were calculated using the treasury stock method, as presented in the table below. The Company determined that the impact to diluted earnings per share would be immaterial if calculated under the two-class method for the three months ended March 31, 2020.
