Discontinued Operations and Disposal Groups [Abstract] |
Schedule of Discontinued Operations | A binding arbitration was concluded in 2016 with respect to certain product performance claims made by an SISD customer, for which the Company remained responsible under the indemnity provisions of the sale transaction. In that proceeding, the tribunal ordered the Company to pay the customer approximately $326,000, primarily representing a refund of the product purchase price. The tribunal also ordered the customer to pay the Company approximately $45,000, primarily representing reimbursement of legal fees. The net settlement of $281,000 was recorded in discontinued operations in 2016, along with $123,000 of legal fees. The tax benefit related to this expense was $149,000, resulting in a net loss from discontinued operations of $255,000.
