Debt And Credit Facilities [Abstract]
Debt And Credit Facilities	Debt and Credit Facilities Mortgage Note Payable In connection with the purchase of our corporate headquarters in June 2003, we recorded a $54.0 million mortgage note payable to a financial institution collateralized by the commercial real property acquired. The balance on the mortgage note payable was $35.7 million and $38.1 million as of November 30, 2012 and 2011, respectively. The mortgage note payable carries a 20-year amortization, and in the second quarter of fiscal year 2007, we amended the mortgage note payable such that it now carries a fixed annual interest rate of 5.50%. The $34.4 million principal balance that will be remaining at the end of the 10-year term will be due as a final lump sum payment on July 1, 2013. Under the currently applicable terms of the mortgage note agreements, we are prohibited from acquiring another company without prior consent from the lender unless we maintain at least $50.0 million of cash or cash equivalents and meet other non-financial terms as defined in the agreements. In addition, we are subject to certain non-financial covenants pursuant to the terms of the mortgage note agreements. As of November 30, 2012, we were in compliance with all covenants. Credit Facility In December 2011, we and one of our subsidiaries entered into an Amended and Restated Credit Agreement (the "2011 Credit Facility"). In May 2012, we amended certain covenants and terms of the 2011 Credit Facility. The 2011 Credit Facility matures on December 19, 2016 and provides for cash borrowings up to $250.0 million, with a sublimit for swing line loans up to $10.0 million and standby letters of credit in a face amount of up to $50.0 million. We have an option to request that the lenders increase the available commitments by up to an additional $100.0 million for total borrowings of up to $350.0 million. Revolving loans accrue interest at a per annum rate based on, at our option, either (i) the base rate plus a margin ranging from 0.25% to 1.25%, depending on TIBCO’s consolidated leverage ratio or (ii) the London Interbank Offered Rate ("LIBOR") rate plus a margin ranging from 1.25% to 2.25%, depending on TIBCO’s consolidated leverage ratio, for various interest periods. The base rate is defined as the highest of (i) the administrative agent’s prime rate, (ii) the federal funds rate plus a margin equal to 0.50%, and (iii) the LIBOR rate for a one month interest period plus a margin equal to 1.00%. We are also obligated to pay commitment fees for the unused amount of the 2011 Credit Facility, letter of credit fees and other customary fees. Loan origination fees and issuance costs of $3.4 million were incurred since consummation of the 2011 Credit Facility which will be amortized through interest expense over a period of five years. Under certain circumstances, a default interest rate of 2.00% above the applicable interest rate will apply on all obligations during the existence of an event of default under the 2011 Credit Facility. We must maintain a minimum consolidated interest coverage ratio of 3.5:1.0 and a maximum consolidated leverage ratio of 3.25:1.0 in addition to other customary affirmative and negative covenants. The maximum consolidated leverage ratio decreases to 3.00:1.00 and then to 2.75:1.00 with respect to the second fiscal quarter of our fiscal years 2013 and 2014, respectively. As of November 30, 2012, we were in compliance with all covenants under the 2011 Credit Facility. As of November 30, 2012, we had no outstanding borrowings under the 2011 Credit Facility. Line of Credit We have a $20.0 million revolving line of credit that matures in June 2013 (the "Line of Credit"). The revolving line of credit is available for cash borrowings and for the issuance of letters of credit up to $20.0 million. The Line of Credit contains financial covenants substantially identical to those of the 2011 Credit Facility, as well as other customary affirmative and negative covenants. As of November 30, 2012, we were in compliance with all covenants under the line of credit. In connection with the mortgage note, we entered into an irrevocable letter of credit in the amount of $13.0 million collateralized under the Line of Credit which renews for successive one-year periods, until the mortgage note payable has been satisfied in full. In addition, as of November 30, 2012 we had a total of $1.0 million outstanding with respect to letters of credit in connection with sales and lease transactions. Guarantee Credit Line and Restricted Cash We have a revolving guarantee credit line of approximately $13.0 million (the "Guarantee Credit Line") available for issuance of bank guarantees denominated in foreign currency. Issued bank guarantees were approximately $12.5 million and $11.4 million in fiscal years 2012 and 2011, respectively, and were collateralized by pledging the equivalent amount under restricted cash as required under our Guarantee Credit Line. Additionally, other contractual commitments also require us to pledge cash as security under restricted cash. As of November 30, 2012 and 2011, we had restricted cash of $14.6 million and $13.8 million, respectively, which is included in Other Assets on our Consolidated Balance Sheets.
