Fair Value Disclosures [Abstract]
Fair Value Measurements	9. Fair Value Measurements The fair values of cash and cash equivalents, accounts receivable and accounts payable and accrued liabilities approximate their carrying values because of the short-term nature of these financial instruments. The fair value of the Company’s long-term debt, determined based on the future cash flows associated with each debt instrument discounted using an estimate of the Company’s current borrowing rate for similar debt instruments of comparable maturity, is approximately equal to their carrying value at June 30, 2013 and December 31, 2012. FASB ASC 820-10-05 establishes a fair value hierarchy that prioritizes the inputs used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurement) and the lowest priority to unobservable inputs (Level 3 measurement). The fair value of the Company’s cash and cash equivalents and long-term debt are classified as Level 1 and Level 2 measurements, respectively. The fair values of accounts receivable and accounts payable and accrued liabilities are classified as Level 2 measurements.
