HF-T1 Distribution Center Loan

To finance construction and improvements to the Company’s North American distribution center, the Company’s joint venture with HF Logistics I, LLC (“HF”), HF Logistics-SKX, LLC (the “JV”), through a wholly-owned subsidiary of the JV (“HF-T1”), entered into a $129.5 million construction loan agreement which matures on March 18, 2025 (the “HF-T1 2020 Loan”) with interest of LIBOR Daily Floating Rate plus a margin of 1.75% per annum.

HF-T1 also entered into an ISDA master agreement (together with the schedule related thereto, the “Swap Agreement”) with Bank of America, N.A. to govern derivative and/or hedging transactions that HF-T1 concurrently entered into with Bank of America, N.A. Pursuant to the Swap Agreement, on August 14, 2015, HF-T1 entered into a confirmation of swap transactions (the “Interest Rate Swap”) as amended (the “Swap Agreement Amendment”) on March 18, 2020 with Bank of America, N.A with a maturity date of March 18, 2025. The Swap Agreement Amendment fixes the effective interest rate on the HF-T1 2020 Loan at 2.55% per annum. The HF-T1 2020 Loan and Swap Agreement Amendment are subject to customary covenants and events of default. Bank of America, N.A. also acts as a lender and syndication agent under the Company’s revolving credit facility.

As of both September 30, 2022 and December 31, 2021, the Interest Rate Swap had an aggregate notional amount of $129.5 million. Under the terms of the Swap Agreement Amendment, the Company will pay a weighted-average fixed rate of 0.795% on the notional amount and receive payments from the counterparty based on the 30-day LIBOR rate, effectively modifying the Company’s exposure to interest rate risk by converting floating-rate debt to a fixed rate of 4.08%.
