Stock repurchase program

12. Stock repurchase program

We use the cost method to account for treasury stock purchases, under which the price paid for the stock is charged to the treasury stock account.  Repurchases of our common stock are accounted for as of the settlement date.  During 2023 and 2022, we did not repurchase any shares of our common stock.  From January 1, 2005 through December 31, 2019, we repurchased a total of 4,044,842 shares of common stock for $32.1 million, at an average price of $7.94 per share.
