As of January 31, 2017, the Company had a secured, revolving credit facility, as described below (the “Credit Agreement”). The Credit Agreement was a secured revolving facility in the maximum principal amount of $20.0 million and a maturity of August 31, 2017, among the Company, as borrower, HSBC Bank USA, N.A., as administrative agent and several banks and other financial institutions from time to time as lenders thereunder (initially consisting of HSBC Bank USA, N.A. and First Victoria National Bank). In November 2016, the Company reduced the commitment to $10.0 million from $20.0 million. In March 2017, the Company repaid all outstanding obligations under the Credit Agreement and terminated that agreement. The Credit Agreement provided for Eurodollar loans, which bore interest at the Eurodollar base rate, plus a margin of from 2.50% to 3.50% based on the Company’s leverage ratio and for ABR loans which bore interest at the applicable base rate plus a margin of from 1.50% to 2.50% based on the Company’s leverage ratio. As of January 31, 2017, the margin for ABR loans was 250 basis points and the margin for Eurodollar loans was 350 basis points. The Company agreed to pay a commitment fee on the unused portion of the Credit Agreement of 0.375% to 0.50%. Up to $10.0 million of available borrowings under the Credit Agreement may have been utilized to secure letters of credit. On August 22, 2014, Seamap Singapore entered into a $15.0 million credit facility (the “Seamap Credit Facility”) with The Hongkong and Shanghai Banking Corporation Limited (“HSBC-Singapore”). The facility consisted of a $10.0 million term loan, a $3.0 million revolving credit facility, and a $2.0 million banker’s guarantee facility. In April 2017, the company prepaid all amounts outstanding under the Seamap Credit Facility and canceled that facility. The term loan portion of the Seamap Credit Facility provided for eleven quarterly principal payments of $800,000 and a final payment of the remaining $1.2 million on or before August 31, 2017. Interest on the term facility was payable quarterly at LIBOR plus 2.75%. Under the Seamap Credit Facility, Seamap Singapore may have borrowed up to $3.0 million for a period of one to three months to be utilized for working capital and other general corporate purposes. Borrowings under the revolving credit facility bore interest at LIBOR plus 3.00%. The Company’s average borrowings under the Credit Agreement and the Seamap Credit Facility for the fiscal years ended January 31, 2018 and 2017 were approximately $801,000 and $12.2 million, respectively.
