​ During the year ended December 31, 2021, the Company reduced the carrying value of the used mill equipment to $nil to reflect management’s estimate of recoverability. The Company recorded this reduction as an operating loss of $5,500 in our Consolidated Statements of Income/(Loss). The inputs used to value the used mill equipment included the duration this equipment has been actively marketed by an independent broker, and the current competitive market conditions for used equipment yielding no sales. Such inputs involved a high degree of subjectivity and resulted in management not having the ability to estimate recoverable sales proceeds with sufficient certainty. The used mill equipment continues to be marketed by the independent broker.
