In 2016, the Company entered into an agreement to sell one of its manufacturing facilities for gross proceeds of $5.0 million, less costs associated with the transaction of $0.3 million, or net proceeds of $4.7 million. As a part of the transaction, the Company entered into a lease for the property from the purchaser for an initial period of 13 years. In June 2017, the agreement was amended extending the term through June 2031. This sale-leaseback has been accounted for as a financing transaction with a current effective interest rate of 4.53%. Payments made by the Company are allocated between interest expense and a reduction to the sale-leaseback financing liability.
