Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Fair Value of Financial Instruments We base disclosures about fair value of our financial instruments on pertinent information available to management as of December 31, 2016 and 2015. We exercise considerable judgment when interpreting market data and developing estimated fair value. Accordingly, the estimates presented herein are not necessarily indicative of the amounts that we could realize on disposition of the financial instruments. Different market assumptions and/or estimation methodologies may have a material effect on estimated fair value amounts. We base our estimates of the fair value of: (i) cash and cash equivalents, restricted cash, accounts receivable, accounts payable and accrued expenses on their carrying values due to their relatively short maturity; (ii) our debt for which trading prices are publicly available on observable market data (a Level 2 input) (that debt had an estimated fair value of approximately $1.0 billion at December 31, 2016 and 2015); and (iii) our debt for which trading prices are not publicly available on a discounted cash flow model using effective borrowing rates for debt with similar terms, loan to estimated fair value of collateral and remaining maturities (a Level 3 input) (that debt had an estimated fair value of $364.6 million and $438.8 million at December 31, 2016 and 2015, respectively). The estimated fair value of all our debt was $1.4 billion and $1.5 billion at December 31, 2016 and 2015, respectively. The carrying value of our debt was $1.3 billion and $1.4 billion at December 31, 2016 and 2015, respectively.
