Commitments And Contingencies [Abstract]
Commitments And Contingencies	17.Commitments and Contingencies We may, from time to time, be subject to litigation and other claims in the ordinary course of our business. We accrue for estimated losses arising from such litigation or claims if it is probable that an asset has been impaired or a liability has been incurred and the amount of the loss can be reasonably estimated. To estimate whether a loss contingency should be accrued by a charge to income, we evaluate, among other factors, the degree of probability of an unfavorable outcome and the ability to make a reasonable estimate of the amount of the loss. Since the outcome of litigation and claims is subject to significant uncertainty, changes in the factors used in our evaluation could materially impact our financial position or results of operations. We are currently unaware of any significant pending litigation affecting us other than the matters set forth below. We were a party to a civil suit filed by 3CEMS, a Cayman Islands and People’s Republic of China corporation, in the U.S. District Court for the Eastern District of Michigan and served on us on or about January 7, 2015. The suit alleged that we breached our contractual obligations by failing to pay for component parts to be used to manufacture optical video scopes for our discontinued Commercial Products Business Unit. 3CEMS alleged that it purchased the component parts in advance of the receipt of orders based upon instructions they claimed to have received from us. The suit alleged damages of not less than $4.0 million. In July 2017, we entered into an agreement with 3CEMS to settle this suit and recorded the expense in the fourth quarter of fiscal 2017. As part of the settlement, we agreed to pay 3CEMS $1,000,000 in four equal payments of $250,000 each over a period of ten months beginning in August 2017 (see Note 12, “Severance, Impairment and Other Charges” for further discussion). In May 2017, a judge in a trade secrets case brought by Perceptron, granted the defendants’ motions for summary disposition. Furthermore, in January 2018 the judge granted their motions for recovery of their attorney fees in the amount of $675,000, plus interest. We are appealing the court’s decision to grant summary disposition and the award of the attorney fees. In the second quarter of fiscal 2018, we recorded a charge in the amount of $675,000 relating to this matter (see Note 12 “Severance, Impairment and Other Charges” for further discussion). Due to our appeal of the court decisions in the trade secrets case, the timing of any payments related to this matter is unknown to us at this time. As part of our routine evaluation procedures, we identified a potential concern regarding the employment status and withholding for several individuals in one of our foreign jurisdictions. During fiscal 2015, we estimated a range of the potential financial liability related to this matter of €486,000 to €1 million. We were not able to reasonably estimate the amount within this range that we would be required to pay for this matter. As a result, in fiscal 2015, we recorded a reserve of €486,000 (equivalent to approximately $582,000) representing the minimum amount we estimated would be paid. In the fourth quarter of fiscal 2016, we received the final notice regarding this issue, and as a result, we recorded an additional expense of €227,000 (equivalent to approximately $272,000). To date, we have paid a total of €677,000 (equivalent to approximately $810,000). We believe that the Slovakian authorities have closed this issue and therefore, in the second quarter of fiscal 2018, we reversed the remaining accrual. In the third quarter of fiscal 2018, the Canadian Revenue Agency (CRA) completed a Goods and Services Tax/Harmonized Sales Tax Returns (GST/HST) audit. Based on this audit, the CRA has preliminarily proposed to assess us approximately C$1,266,000 (equivalent to approximately $982,000) in taxes related to sales from 2013 through 2018. CRA has indicated that we are entitled to invoice our customers to recover this amount and our customers are required to remit payment. In addition, we will be charged interest and penalties if this preliminary finding is finalized. Our response to the CRA was delivered in April 2018. We did not record an accrual related to this preliminary audit finding because we are disputing several of the CRA’s conclusions, as well as due to the fact that we expect to ultimately receive the funds from our customers (excluding any interest or penalties), although there may be a timing difference between when we must pay the CRA and when we collect the funds from our customers.
