Restructuring Charges [Abstract]
CORPORATE HEADQUARTERS RELOCATION AND LEASE EXIT COSTS	CORPORATE HEADQUARTERS RELOCATION AND LEASE EXIT COSTS During the first quarter of 2012, we made the decision to relocate our corporate headquarters from Houston, Texas to Euless, Texas. The move was completed in July 2012. As a result of this decision, we have paid severance costs to employees that did not relocate with the Company, as well as other employee-related and general moving costs. For the three and six months ended June 30, 2013, we recorded approximately $0.3 million and $0.5 million, respectively, for these moving costs. For the three and six months ended June 30, 2012, we recorded approximately $0.5 million and $1.6 million, respectively, for moving costs. These costs are included in selling, general and administrative ("SG&A") expenses on the condensed consolidated statements of operations. In connection with the relocation, we ceased use of our leased corporate office space in Houston effective July 21, 2012. Thus, during the third quarter of 2012, we recorded a $0.4 million non-cash charge to SG&A expenses for the net present value of the difference between the remaining lease payments and the market value we believe we could obtain for a sublease of the space over the remainder of the term. We will continue to incur rent expense for the remainder of the lease term, which we include in SG&A expenses; however, the expense will be reduced by the amortization of the cease-use obligation over the remaining lease term. The associated nominal accretion expense is included as a charge to SG&A expenses over the remaining lease term. We did not sublease the office space during the first half of 2013, thus no rental income is recorded during the period for this space. We recorded credits of approximately $0.1 million in amortization of the cease-use obligation during each of the three and six months ended June 30, 2013.
