Shareholders’ Equity [Abstract]
Shareholders' Equity	5. Shareholders’ Equity Through September 30, 2020, we had announced authorizations by our Board of Directors of repurchases of shares of common stock, which in the aggregate, authorized expenditures of up to $2,800,000. As of September 30, 2020, $115,018 was available to be repurchased under announced repurchase authorizations. Shares repurchased are being held in treasury stock until they are reissued or retired at the discretion of the Board of Directors. No shares were repurchased during the three months ended September 30, 2020 as we have temporarily suspended our share buyback program in the midst of the coronavirus (COVID-19) pandemic. During the nine months ended September 30, 2020, 58 shares of common stock at a total cost of $47,976 were netted and surrendered as payment for minimum statutory withholding obligations in connection with the vesting of outstanding stock awards. Shares surrendered by the participants in accordance with the applicable award agreements and plan are deemed repurchased by us but are not part of publicly announced share repurchase programs.
