NOTE 22 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 common 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 year ending December 31, 2019 is presented below:


	Year ended
	December 31,
(dollars and shares in thousands, except per share data)	2019
Net income	$	29,540
Dividends and undistributed earnings allocated to participating securities		647
Net income available to common shareholders	$	28,893
Weighted-average common shares outstanding for basic earnings per share		14,736
Dilutive effect of stock-based awards		357
Weighted-average common shares outstanding for diluted earnings per share		15,093
Earnings per common share:
Basic earnings per common share	$	1.96
Diluted earnings per common share	$	1.91

For the years ending December 31, 2018 and 2017, 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 years ending December 31, 2018 and 2017.
