The following table reconciles the number of shares used in calculating basic and diluted earnings per share:


	Three Months Ended June 30,				Six Months Ended June 30,
(in thousands)	2024		2023		2024		2023
Basic weighted-average shares outstanding		79,627		80,145		79,656		80,087
Incremental shares due to:
Performance shares		49		226		42		177
Restricted stock units		65		45		58		33
Diluted weighted-average shares outstanding		79,741		80,416		79,756		80,297

For stock-based awards, the dilutive effect is calculated using the treasury stock method. Under this method, the dilutive effect is computed as if the awards were exercised at the beginning of the period (or at time of issuance, if later) and assumes the related proceeds were used to repurchase common stock at the average market price during the period. Related proceeds include future compensation cost associated with the stock award.

For the three and six months ended June 30, 2024, there were approximately 19,000 and 78,000 stock-based awards, respectively, that were excluded from the calculation of diluted earnings per share as they were anti-dilutive. For the three and six months ended June 30, 2023, there were approximately 34,000 and 68,000 stock-based awards, respectively, that were excluded from the calculation of diluted earnings per share as they were anti-dilutive. Anti-dilutive stock-based awards could be dilutive in future periods.

On August 31, 2022, our board of directors authorized management to repurchase up to $200.0 million of our common stock with no set time limit for the repurchase (the 2022 Repurchase Program). Shares under the 2022 Repurchase Program may be repurchased in open market transactions, including pursuant to trading plans adopted in accordance with Rule 10b5-1 of the Securities Exchange Act of 1934 (a Trading Plan), or through privately negotiated transactions. The timing, manner, price and amount of repurchases will be determined according to, and subject to, the terms of a Trading Plan, and, subject to the terms of a Trading Plan, the 2022 Repurchase Program may be suspended, terminated or modified at any time for any reason.

During the three and six months ended June 30, 2024, we repurchased 609,624 shares of our common stock for total consideration of $25.0 million under the 2022 Repurchase Plan. During the three and six months ended June 30, 2023, we repurchased 8,761 shares of our common stock for total consideration of $0.4 million under the 2022 Repurchase Plan. At June 30, 2024, we had remaining authorization of $100.0 million for future stock repurchases under the 2022 Repurchase Program. Transaction costs are not counted against authorized funds.

We record share repurchases upon trade date as opposed to the settlement date. We record a liability to account for repurchases that have not been cash settled. We retire shares upon repurchase. Any excess repurchase price over par is recorded in accumulated deficit.
