Fair Value Disclosures [Abstract]
FAIR VALUE OF FINANCIAL INSTRUMENTS:	5. FAIR VALUE OF FINANCIAL INSTRUMENTS: As cash and cash equivalents and restricted cash have maturities of less than three months, the carrying values of cash and cash equivalents and restricted cash approximate fair value (Level 1 of the fair value hierarchy). The carrying values of accounts receivable, accounts payable and accrued liabilities and accrued interest payable approximate fair value due to the short maturity of these instruments (Level 2 of the fair value hierarchy). The fair value of the Company’s notes payable was approximately $184 million as of December 31, 2014. The fair value of the Company’s notes payable was estimated based on a discounted cash flow analysis using a discount rate representing the Company’s estimate of the rate that would be used by market participants (Level 2 of the fair value hierarchy). Changes in assumptions or estimation methodologies may have a material effect on these estimated fair values.
