Earnings per Share [Abstract]

Earnings per Common Share

Earnings per share was calculated for the three and nine months ended September 30, 2020 and 2019, respectively. Basic earnings per share is based upon the weighted average number of common shares outstanding, exclusive of unearned shares held by the Employee Stock Ownership Plan of Lake Shore Bancorp, Inc. (the “ESOP”), unearned shares held by the Lake Shore Bancorp, Inc. 2006 Recognition and Retention Plan (“RRP”), and unearned shares held by the Lake Shore Bancorp, Inc. 2012 Equity Incentive Plan (“EIP”). Diluted earnings per share is based upon the weighted average number of common shares outstanding and common share equivalents that would arise from the exercise of dilutive securities. Stock options are regarded as potential common stock and are considered in the diluted earnings per share calculations to the extent they would be dilutive and computed using the treasury stock method.
