A total of 1,900,000 common shares were authorized for granting stock awards under the 2014 Incentive Plan, of which 1,010,110 were available for issuance as of December 31, 2019. The 2014 Incentive Plan terminates on December 13, 2023. Employee Stock Purchase Plan The 1999 Employee Stock Purchase Plan (Purchase Plan) allowed eligible employees to purchase the Company’s common shares through payroll withholding at a discount of up to 15% off the market price at the end of each six-month purchase period. For purchase periods between January 1, 2017 and June 30, 2019, the purchase price was 100% of the market price at the end of each six-month purchase period. For purchase periods beginning after June 30, 2019, the purchase price is 85% of the market price at the end of each six-month purchase period. Of the 1,400,000 common shares authorized to be issued under the Purchase Plan, 349,763 were available for purchase as of December 31, 2019. At the discretion of the Company, shares purchased under the Purchase Plan can be either new issue shares or shares purchased in the open market. To provide shares for purchases for the Purchase Plan, 13,432 common shares were issued in January 2020 for the purchase period ended December 31, 2019, 3,672 common shares were purchased in the open market in 2019, 7,757 common shares were purchased in the open market in 2018, and 4,202 common shares were purchased in the open market and 5,284 common shares were issued in 2017. Dividend Reinvestment and Share Purchase Plan On May 3, 2018, the Company filed a shelf registration statement with the SEC for the issuance of up to 1,500,000 common shares under the Company's Automatic Dividend Reinvestment and Share Purchase Plan (the Plan), which permits shares purchased by participants in the Plan to be either new issue common shares or common shares purchased in the open market. The shelf registration for the Plan expires on May 3, 2021. In October 2019, the Company began issuing new shares to satisfy the requirements of the Plan. In 2019, 53,339 common shares were issued, and 109,807 shares were purchased in the open market to provide shares for the Plan. In 2018, 116,822 common shares were purchased in the open market to provide shares for the Plan. Although shares are purchased on the open market, they must be sold under the registration statement due to the features of the plan, leaving 1,220,032 common shares available for purchase or issuance under the Plan as of December 31, 2019. The shelf registration statement replaced the Company’s prior shelf registration statement, which provided for the issuance of up to 1,500,000 common shares under the Plan. Common shares purchased in the open market under the Plan pursuant to the Company’s prior shelf registration statement totaled 53,853 in 2018 and 87,634 in 2017. New common shares issued under the Plan pursuant to the Company’s prior shelf registration statement totaled 97,698 in 2017. Earnings Per Share The numerator used in the calculation of both basic and diluted earnings per common share is net income with no adjustments in 2019, 2018 and 2017. The denominator used in the calculation of basic earnings per common share is the weighted average number of common shares outstanding during the period excluding nonvested restricted shares granted to the Company’s directors and employees, which are considered contingently returnable and not outstanding for the purpose of calculating basic earnings per share. The denominator used in the calculation of diluted earnings per common share is derived by adjusting basic shares outstanding for the items listed in the following reconciliations.
|  | 2019 |  |  | 2018 |  |  | 2017 |
Weighted Average Common Shares Outstanding – Basic |  |  | 39,720,847 |  |  |  | 39,599,944 |  |  |  | 39,457,261 |
