Subsequent Events [Abstract]
Subsequent events	13. Subsequent events On January 31, 2024, we announced that our Board of Directors appointed Kevin Hykes as President and Chief Executive Officer, effective February 12, 2024 to succeed Nadim Yared, who previously announced his plans to retire upon the appointment of his successor. In connection with a transition and consulting agreement we entered into with Mr. Yared, we also modified certain terms and conditions of Mr. Yared’s stock options granted under the 2001 Plan and 2021 Plan, however, the impact of this modification on the amount of stock-based compensation expense cannot yet be quantified.

The entire disclosure for significant events or transactions that occurred after the balance sheet date through the date the financial statements were issued or the date the financial statements were available to be issued. Examples include: the sale of a capital stock issue, purchase of a business, settlement of litigation, catastrophic loss, significant foreign exchange rate changes, loans to insiders or affiliates, and transactions not in the ordinary course of business.
