Fair Value Disclosures [Abstract]  
Fair Value Measurements Fair Value Measurements
The accounting standard for fair value measurements provides a framework for measuring fair value and expands disclosures about fair value measurements. The framework requires the valuation of investments using a three-tiered approach. The statement requires fair value measurement to be classified and disclosed in one of the following categories:
Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets and liabilities;
Level 2: Quoted prices in markets that are not active, or inputs which are observable, either directly or indirectly, for substantially the full term of the asset or liability; or
Level 3: Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e. supported by little or no market activity).
As of December 31, 2021 and 2020, we did not have any financial instruments with significant Level 3 inputs and we did not have any financial instruments that are measured at fair value on a recurring basis.
For certain of our non-derivative financial instruments, including receivables, accounts payable and other accrued liabilities, the carrying amount approximates fair value due to the short-term maturities of these instruments.
