Basic earnings per share (“EPS”) is computed as net income divided by the weighted-average number of shares of common stock outstanding for the period. Diluted EPS is computed assuming conversion of all potentially dilutive securities including the dilutive effect of stock options, unvested restricted stock awards and other potentially dilutive securities. The table below presents the weighted-average number of shares of common stock used to calculate basic and diluted earnings per share:


	Three Months Ended September 30,				Nine Months Ended September 30,
(in thousands)	2023		2022		2023		2022
Weighted-average number of shares of common stock for calculating basic earnings per share		24,487		24,379		24,461		24,342
Effect of potentially dilutive securities from equity-based compensation		38		125		66		174
Weighted-average number of shares of common stock for calculating diluted earnings per share		24,525		24,504		24,527		24,516

There were 1,800 anti-dilutive securities excluded from the computation of diluted earnings per share for the nine months ended September 30, 2023, and 7,315 anti-dilutive securities excluded from the computation of diluted earnings per share for the same period in 2022.

The Company has in the past made purchases of shares of its common stock from time to time in over-the-counter market (NASDAQ) transactions, through privately negotiated, large block transactions and through a share repurchase plan, in accordance with Rule 10b5-1 of the Securities Exchange Act of 1934. In August 2015, the Company’s Board of Directors authorized the Company to repurchase up to 2,000,000 shares of the Company's outstanding common stock (the “Repurchase Plan”). The amount and time of the specific repurchases are subject to prevailing market conditions, applicable legal requirements and other factors, including management’s discretion. All shares repurchased by the Company are canceled and returned to the status of authorized but unissued shares of common stock. There can be no assurance that any authorized shares will be repurchased, and the Repurchase Plan may be modified, extended or terminated by the Company’s Board of Directors at any time. There were no shares repurchased during the three and nine months ended September 30, 2023 and 2022. As of September 30, 2023, 1,309,805 shares remained authorized for repurchase under the Repurchase Plan.
