Debt

Teradata's $600 million term loan is payable in quarterly installments, which commenced 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 December 31, 2017, the term loan principal outstanding was $540 million and carried an interest rate of 3.375%. Unamortized deferred issuance costs of approximately $1 million are being amortized over the five-year term of the loan. The Company was in compliance with all covenants as of December 31, 2017.

Annual contractual maturities of outstanding principal on the term loan at December 31, 2017, are as follows:

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.

Teradata's revolving credit facility (the “Credit Facility”) has a borrowing capacity of $400 million. 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 December 31, 2017, the Company had $240 million in borrowings outstanding under the Credit Facility, which carried an interest rate of 5.0%, leaving $160 million in additional borrowing capacity available. Unamortized deferred costs on the original credit facility and new lender fees of approximately $1 million are being amortized over the five-year term of the credit facility. The Company was in compliance with all covenants as of December 31, 2017.
