Fifth Amended and Restated Share Repurchase Program [Member]
Equity [Line Items]
Description of share repurchase program	The Company is authorized through the SRP to repurchase shares from stockholders who purchased their shares directly from the Company as opposed to another stockholder or received their shares through a non-cash transfer and have held their shares for at least one year. The SRP is governed by the terms of the Sixth Amended and Restated Share Repurchase Program (the “Sixth SRP”) adopted by the board on December 17, 2025, effective on February 1, 2026. Repurchases are made in the Company’s sole discretion. In the case of repurchases made upon the death of a stockholder or qualifying disability (“Exceptional Repurchases”), as defined in the SRP, the one year holding period does not apply. Under the Sixth SRP, the board has the discretion to establish the proceeds available to fund repurchases each quarter and can use proceeds from all sources available to the Company, in the board’s sole discretion. The board also has the discretion to determine the amount of repurchases, if any, to be made each quarter based on its evaluation of the Company’s business, cash needs and any other requirements of applicable law. A copy of the Sixth SRP is available on the Company’s website. During the suspension, the Company did not repurchase shares under the SRP.
