Debt And Credit Facility [Line Items]
Long-term Debt, Description				On May 11, 2011, TSI, LLC entered into a $350,000 senior secured credit facility (“2011 Senior Credit Facility”). The 2011 Senior Credit Facility consists of a $300,000 term loan facility (“2011 Term Loan Facility”), and a $50,000 revolving loan facility (“2011 Revolving Loan Facility”). The 2011 Term Loan Facility was issued at an original issue discount (“OID”) of 1.0% or $3,000.									The 2007 Term Loan Facility was set to expire on the earlier of February 27, 2014, or August 1, 2013, if the Senior Discount Notes were still outstanding. There were no outstanding amounts under the 2007 Revolving Loan Facility as of such date. The 2007 Term Loan Facility was repaid at face value plus accrued and unpaid interest of $447 and fees related to the letters of credit of $27. The total cash paid in connection with this repayment was $164,475 as of May 11, 2011 with no early repayment penalty. The Company determined that the 2011 Senior Credit Facility was not substantially different than the 2007 Senior Credit Facility for certain lenders based on the less than 10% difference in cash flows of the respective debt instruments. A portion of the transaction was therefore accounted for as a modification of the 2007 Senior Credit Facility and a portion was accounted for as an extinguishment. In the three months ended June 30, 2011, the Company recorded refinancing charges of approximately $634, representing the write-off of the remaining unamortized debt costs related to the 2007 Senior Credit Facility, which is included in loss on extinguishment of debt in the accompanying condensed consolidated statements of operations.	A portion of the proceeds from the 2011 Senior Credit Facility were also used to pay the remaining principal amount on the Senior Discount Notes of $138,450 plus a call premium of 1.833% of the principal amount thereof totaling approximately $2,538 and accrued interest of $5,457. The accrued interest included interest through May 11, 2011 of $4,188, plus 30 days of additional interest of $1,269, representing the interest charge during the 30 day notification period. The Company determined that the 2011 Senior Credit Facility was substantially different than the Senior Discount Notes. In the three months ended June 30, 2011, the Company wrote-off unamortized deferred financing costs of approximately $916 related to the redemption of the Senior Discount Notes, which is included in loss on extinguishment of debt in the accompanying condensed consolidated statements of operations.
