Commitments And Contingencies Disclosure [Abstract]
Contingencies	10. Contingencies From time to time, we are involved in legal proceedings that we consider to be in the normal course of business. We record accruals for losses related to those matters against us that we consider to be probable and that can be reasonably estimated. Based on available information, in the opinion of management, settlements, arbitration awards and final judgments, if any, that are considered probable of being rendered against us in litigation or arbitration in existence at December 31, 2021 and that can be reasonably estimated are either reserved against or would not have a material adverse effect on our financial condition, results of operations or cash flows.

The entire disclosure for loss and gain contingencies. Describes any existing condition, situation, or set of circumstances involving uncertainty as of the balance sheet date (or prior to issuance of the financial statements) as to a probable or reasonably possible loss incurred by an entity that will ultimately be resolved when one or more future events occur or fail to occur, and typically discloses the amount of loss recorded or a range of possible loss, or an assertion that no reasonable estimate can be made.
