Debt Disclosure [Abstract]
Debt	Debt On March 25, 2015, Teradata replaced its existing five-year, $300 million revolving credit facility with a new $400 million revolving credit facility (the “Credit Facility”). The Credit Facility ends on March 25, 2020 at which point any remaining outstanding borrowings would be due for repayment unless extended by agreement of the parties for up to two additional one-year periods. The interest rate charged on borrowings pursuant to the Credit Facility can vary depending on the interest rate option the Company chooses to utilize and the Company’s leverage ratio at the time of the borrowing. In the near term, Teradata would anticipate choosing a floating rate based on the London Interbank Offered Rate (“LIBOR”). The Credit Facility is unsecured and contains certain representations and warranties, conditions, affirmative, negative and financial covenants, and events of default customary for such facilities. As of March 31, 2015, the Company had no borrowings outstanding under the Credit Facility, leaving $400 million in additional borrowing capacity available under the Credit Facility. The Company was in compliance with all covenants as of March 31, 2015. Also on March 25, 2015, Teradata closed on a new senior unsecured $600 million five-year term loan, the proceeds of which were used to pay off the remaining $247 million of principal on its existing term loan, pay off the $220 million outstanding balance on the prior credit facility, and to fund share repurchases. The $600 million term loan is payable in quarterly installments, which will commence on March 31, 2016, with all remaining principal due in March 2020. The outstanding principal amount under the term loan agreement bears interest at a floating rate based upon a negotiated base rate or a Eurodollar rate plus a margin based on the leverage ratio of the Company. As of March 31, 2015, the term loan principal outstanding was $600 million and carried an interest rate of 1.4375%. The Company was in compliance with all covenants as of March 31, 2015. Teradata’s term loan is recognized on the Company’s balance sheet at its unpaid principal balance, and is not subject to fair value measurement. However, given that the loan carries a variable rate, the Company estimates that the unpaid principal balance of the term loan would approximate its fair value. If measured at fair value in the financial statements, the Company’s term loan would be classified as Level 2 in the fair value hierarchy.
