Operating loss carryforward description As a result of losses incurred in the past, the Company has net operating loss ("NOL") carry-forwards that are available to offset future taxable income and subject to expiration rules and to Internal Revenue Code of 1986, as amended (“IRC”) §382. In general, IRC §382 may impact the amount of NOLs that can be utilized each year after certain ownership changes occur. An ownership change occurs, generally, if the percentage of stock of the loss corporation owned by one or more 5% shareholders has increased by more than 50 percentage points relative to the lowest percentage of stock of the loss corporation owned by the same 5% shareholders at any time during the testing period (generally, the three-year period preceding a testing date).      
Operating loss carryforwards, limitations on use description Pursuant to an IRC §382 limitation analysis performed by the Company, it was noted that an ownership change, as defined under IRC §382, occurred on March 29, 2018. Usage of NOL’s generated prior to March 29, 2018 will be limited to $3.0 million for calendar years 2019 through 2022 and $0.6 million from 2024 through 2039 for both federal and state purposes. Of the federal net operating loss and the state net operating loss carryforward amounts, $22.5 million and $22.0 million are subject to the IRC §382 limitation, respectively. There is not an IRC §382 limitation on the foreign NOLs.      
Tax credit carryforward, limitations on use description In the ordinary course of its business the Company incurs costs that, for tax purposes, are determined to be qualified research expenditures within the meaning of IRC §41 and are, therefore, eligible for the Increasing Research Activities credit under IRC §41. R&D credit carryovers generated prior to March 29, 2018 are limited under IRC §383 to $0.3 million a year for both federal and state purposes. The Company has adjusted the deferred tax assets related to Federal R&D credit carryover to account for any tax credits that will expire unused due to the IRC §383 limitations.
