Note 5 – Sales, Contract Assets and Contract Liabilities

The Company recognized no revenue during each of the years ended December 31, 2020 and 2019. During the year ended December 31, 2020, the Company recognized cost of goods sold of $450,000 from a project that the Company anticipates will show a loss on the sale when completed and a second project that was completed, but has been deemed as potentially uncollectable. During the year ended December 31, 2020, the recognized cost of goods sold was offset by recorded adjustments totaling $171,000 related to the reversal of accruals for product warranties that expired on seven completed projects from the years 2016 and 2017. The Company recorded an adjustment of $1,000 for the year ended December 31, 2019 related to additional warranty costs incurred for previously completed contracts. The Company had contract assets of $92,000 and $39,000 and contract liabilities of $94,000 and $50,000 at December 31, 2020 and 2019, respectively.
