On December 28, 2016, TSM entered into a $35,500 credit agreement with a commercial bank in Puerto Rico. The agreement consists of three term loans: (i) Term Loan A in the principal amount of $11,187, (ii) Term Loan B in the principal amount of $20,150 and (iii) Term Loan C in the principal amount of $4,116. Term Loan A matures in October 2023 while the Term Loans B and C mature in January 2024.  Term Loan A was used to refinance the previous $41,000 secured loan payable with the same commercial bank in Puerto Rico.  Proceeds from Term Loans B and C were received on January 11, 2017 and were used to prepay the outstanding principal amount plus accrued interest of the 6.6% Senior Unsecured Notes due January 2021 ($24,000), and fund a portion of a debt service reserve for the Loan (approximately $200).  Pursuant to the credit agreement, interest is payable on the outstanding balance of the Loan at the following annual rate: (1) 1% over LIBOR for Term Loan A, (ii) 2.75% over LIBOR for Term Loan B, and (iii) 3.25% over LIBOR for Term Loan C.  Interest shall be payable commencing on January 1, 2017, in the case of Term Loan A, and on February 1, 2017, in the case of Term Loan B and Term Loan C.  The Credit Agreement includes certain financial and non-financial covenants, including negative covenants imposing certain restrictions on the Corporation’s business.  The Company was in compliance with all these covenants as of December 31, 2016.

The credit agreement is guaranteed by a first mortgage held by the bank on the Company’s land, building, and substantially all leasehold improvements, as collateral for the term of the loan under a continuing general security agreement.  This credit agreement contains certain non-financial covenants, which are customary for this type of facility, including but not limited to, restrictions on the granting of certain liens, limitations on acquisitions and limitations on changes in control and dividends.

The Company may, at its option, upon notice, as specified in the credit agreement, redeem and prepay prior to maturity, all or any part of the Loan and from time to time upon the payment of a penalty fee of 3% during the first year, 2% during the second year and 1% during the third year, and thereafter, at par, as specified in the credit agreement, together with accrued and unpaid interest, if any, to the date of redemption specified by the Company.

Interest expense on the above borrowings amounted to $1,763, $2,435, and $3,639, for the years ended December 31, 2016, 2015, and 2014, respectively.
