That program was exhausted in the third quarter of 2022.

Pursuant to the approved program, the Company may repurchase its common stock from time to time, in amounts and at prices the Company deems appropriate, subject to market conditions and other considerations. The repurchases may be executed using open market purchases, privately negotiated agreements or other transactions. The actual timing, number and value of shares repurchased under the program will be determined by management at its discretion and will depend on a number of factors, including the market price of the Company’s common stock, general market and economic conditions, applicable legal requirements, and compliance with the terms of the Company’s credit agreements. The repurchases may be funded with cash on hand, available borrowings, or proceeds from potential debt or other capital markets sources. The stock repurchase program may be suspended or discontinued at any time without prior notice. There were no share repurchases under the program during the three months ended March 31, 2023 and 2022. Since the inception of all stock repurchase programs (starting in August 2015), the Company has repurchased 11,748,713 shares of common stock for $777,379 (at an average cost per share of $66.17).
