Fair Value of Financial Instruments [Abstract] |
FAIR VALUE OF FINANCIAL INSTRUMENTS | 8. FAIR VALUE OF FINANCIAL INSTRUMENTS The following fair value disclosure was determined by the Company using available market information and discounted cash flow analyses as of June 30, 2011 and December 31, 2010, respectively. The discount rate used in calculating fair value is the sum of the current risk free rate and the risk premium on the date of measurement of the instruments or obligations. Considerable judgment is necessary to interpret market data and to develop the related estimates of fair value. Accordingly, the estimates presented are not necessarily indicative of the amounts that the Company could realize upon disposition. The use of different estimation methodologies may have a material effect on the estimated fair value amounts. The Company believes that the carrying amounts reflected in the consolidated balance sheets at June 30, 2011 and December 31, 2010 approximate the fair values for cash and cash equivalents, accounts receivable, other assets, accounts payable and accrued expenses. The following are financial instruments for which the Company’s estimates of fair value differ from the carrying amounts (in thousands):
|  | June 30, 2011 |  |  | December 31, 2010 |
|  | Carrying |  |  | Fair |  |  | Carrying |  |  | Fair |

Variable rate debt instruments |  | $ | 303,610 |  |  | $ | 295,131 |  |  | $ | 444,610 |  |  | $ | 432,556 |

(a) |  | For purposes of this disclosure, one of the notes is presented gross of the deferred gain of $12.9 million arising from the sale of two properties in 2009 accounted for under the accounting standard for installment sales.
