In December 2022, TotalStone sold its facility in Navarre, Ohio to a nonaffiliated third party for a purchase price of $3.2 million and concurrently entered into a leaseback transaction. The transaction is treated as a failed sale in accordance with U.S. GAAP. The Company therefore recorded a financing liability related to the sale-leaseback in the amount of the sale price. The obligation matures in January 2048 and requires monthly payments of principal and interest. With the sale leaseback, TotalStone signed a lease agreement with a 25-year lease term. The initial annual lease payment of $259.0 thousand increases 2% per annum. The imputed interest rate is 8.10%.
