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 income.		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 income.

Debt Instrument, Issuance Date						2011-05-11
Debt Instrument, Maturity Date								May 11, 2018		May 11, 2016
Debt Instrument, Call Feature						TSI, LLC may prepay the 2011 Term Loan Facility and 2011 Revolving Loan Facility without premium or penalty in accordance with the 2011 Senior Credit Facility, as amended, except that a prepayment premium of 1.0% is payable for any prepayments made after August 22, 2012 and prior to August 23, 2013 only in connection with a repricing transaction that reduces the effective yield of the initial term loans, otherwise the 1.0% prepayment premium would not be applicable.
Debt Instrument, Interest Rate Terms						Borrowings under the 2011 Term Loan Facility, at TSI, LLC’s option, bear interest at either the administrative agent’s base rate plus 3.5% or its Eurodollar rate plus 4.5%, each as defined in the 2011 Senior Credit Facility, as amended. The Eurodollar rate has a floor of 1.25% and the base rate has a floor of 2.25% with respect to the outstanding term loans.
Debt Instrument, Maturity Date, Description						The 2011 Term Loan Facility matures on May 11, 2018, and the 2011 Revolving Loan Facility matures on May 11, 2016.
Debt Instrument, Payment Terms		TSI, LLC is required to pay 0.25% of principal, or $750 per quarter, in respect of such loans. Pursuant to the terms of the 2011 Senior Credit Facility, as amended, these regularly scheduled required quarterly principal payments of $750 per quarter may be reduced by voluntary prepayments. As a result of the $15,000 voluntary prepayment on August 28, 2012 and assuming the Company’s leverage ratio remains below 2.75:1.00, the Company will not be required to pay the next 20 regularly scheduled quarterly principal payments of $750 for the period beginning September 30, 2012 through June 30, 2017 with regularly scheduled required payments resuming on September 30, 2017. If, as of the last day of any fiscal quarter of TSI Holdings, the total leverage ratio, as defined, is greater than 2.75:1.00, TSI, LLC is required to pay $3,750, or 1.25% of principal. As of September 30, 2012, TSI, LLC had a total leverage ratio of 2.38:1.00 and TSI, LLC will not be required to make a principal payment on September 30, 2012. As of September 30, 2012, TSI LLC has made a total of $44,257 in principal payments on the 2011 Term Loan Facility.						Mandatory prepayments are required in certain circumstances relating to cash flow in excess of certain expenditures, asset sales, insurance recovery and incurrence of certain other debt. The 2011 Senior Credit Facility, as amended, contains provisions that require excess cash flow payments, as defined, to be applied against outstanding 2011 Term Loan Facility balances. The excess cash flow is calculated as of December 31 and paid on March 31. The applicable excess cash flow repayment percentage is applied to the excess cash flow when determining the excess cash flow payment.
Debt Instrument, Restrictive Covenants						The terms of the 2011 Senior Credit Facility, as amended, provide for financial covenants which require TSI, LLC to maintain a total leverage ratio, as defined, of no greater than 4.50:1.00 effective March 31, 2012 and thereafter; an interest expense coverage ratio of no less than 2.00:1.00; and a covenant that limits capital expenditures to $40,000 for the four quarters ending in any quarter during which the total leverage ratio is greater than 3.00:1.00 and to $50,000 for the four quarters ending in any quarter during which the ratio is less than or equal to 3.00:1.00 but greater than 2.50:1.00. This covenant does not limit capital expenditures if the ratio is less than or equal to 2.50:1.00.
Debt Instrument, Covenant Compliance						TSI, LLC was in compliance with these covenants as of September 30, 2012 with a total leverage ratio of 2.38:1.00 and an interest expense coverage ratio of 4.33:1.00.
