Commitments and Contingencies Disclosure [Text Block] | Note 18. Contingencies ​ Litigation ​ Overview From time to time, the Company may be subject to legal proceedings and litigation arising in the ordinary course of business, including, but not limited to, inquiries, investigations, audits and other regulatory proceedings, such as described below. The Company records a loss provision when it believes it is both probable that a liability has been incurred and the amount can be reasonably estimated. Unless otherwise disclosed, the Company is unable to estimate the possible loss or range of loss for the legal proceeding described below. Except for the lawsuits described below, the Company believes that there are no claims or actions pending or threatened against it, the ultimate disposition of which would have a material adverse effect on it. Other Contingencies On August 9, 2021, the Company has received a Taxes Notification of Audit Result (“Notice”) from the Texas Comptroller’s Office (the “Comptroller”), for fiscal years between 2016 and 2019, informing the Company that the Comptroller believes the Company did not qualify for certain sales and use tax exemptions on various Research and Development purchases and accordingly the Company is liable for Sale and Use Tax in the amount of approximately $1.0 million including interest charges. The Company paid $0.4 million for the tax notice but challenged the remaining tax assessments and vigorously defended its position. The Comptroller’s office has not made final assessments after the Company’s defenses. However, the management estimated the additional tax assessment will be in the range of $0.2 million to $0.4 million including interest charges.
