The Company entered into a lease agreement dated November 1, 2008 (“2008 Agreement”) with the Development Authority of Wilkinson County (the “Wilkinson County Development Authority”).  Pursuant to the 2008 Agreement, the Wilkinson County Development Authority holds the title to the real and personal property of the Company's McIntyre and Toomsboro manufacturing facilities and leases the facilities to the Company for an annual administrative fee of $50 per year. The Company elected the renewal option on November 1, 2017, which extended the lease through November 1, 2021.  At any time prior to the scheduled termination of the lease, the Company has the option to terminate the lease and purchase the property for a nominal fee plus the payment of any rent payable through the balance of the lease term.  Furthermore, the Company has security interests in the titles held by the Development Authority.  The Company has also entered into a Memorandum of Understanding (the “MOU”) with the Development Authority and other local agencies, under which the Company receives tax incentives in exchange for its commitment to invest in the county and increase employment.  The Company is required to achieve certain employment levels in order to retain its tax incentives.  In the event the Company does not meet the agreed-upon employment targets or the MOU is otherwise terminated, the Company would be subjected to additional property taxes annually.  Based on adverse economic conditions beyond the Company’s control that negatively impacted employment levels, a notice dated February 1, 2016 sent by the Company to the Development Authority of Wilkinson County declared a force majeure, which suspended employment levels defined in the original agreement and preserved tax incentives until further notification of the restart of plant operations.  The Development Authority of Wilkinson County has not challenged the Company’s declaring a force majeure.  The properties subject to these lease agreements are included in Property, Plant and Equipment (net book value of $104,179 at December 31, 2018) in the accompanying consolidated financial statements.
