Accounting Policies [Abstract]
Fair Value of Financial Instruments	The fair value hierarchy has three levels based on the reliability of the inputs used to determine fair value. Level 1 refers to fair values determined based on quoted prices in active markets for identical assets or liabilities. Level 2 refers to fair values determined based on quoted prices for similar assets or liabilities in active markets or inputs that are observable to the asset or liability, either directly or indirectly through market corroboration. Level 3 refers to fair values determined based on unobservable inputs used in the measurement of assets and liabilities at fair value. The estimated fair values of our financial instruments have been determined at discrete points in time based on relevant market information. Our financial instruments consist of cash and cash equivalents, restricted cash, accounts receivable, accounts payable, accrued liabilities and long–term debt. The carrying amounts of our financial instruments, other than our 2023 Notes, approximate fair value because of the short–term nature of the items.

The fair value hierarchy has three levels based on the reliability of the inputs used to determine fair value. Level 1 refers to fair values determined based on quoted prices in active markets for identical assets or liabilities. Level 2 refers to fair values determined based on quoted prices for similar assets or liabilities in active markets or inputs that are observable to the asset or liability, either directly or indirectly through market corroboration. Level 3 refers to fair values determined based on unobservable inputs used in the measurement of assets and liabilities at fair value.

The estimated fair values of our financial instruments have been determined at discrete points in time based on relevant market information. Our financial instruments consist of cash and cash equivalents, restricted cash, accounts receivable, accounts payable, accrued liabilities and long–term debt. The carrying amounts of our financial instruments, other than our 2023 Notes, approximate fair value because of the short–term nature of the items.
