Commitments and Contingencies Disclosure [Abstract]
Contingencies	Contingencies The Company is subject to legal proceedings, which arise in the ordinary course of business. Additionally, U.S. Government contract costs are subject to periodic audit and adjustment. In the third quarter of 2016, the Company's Audit Committee commenced an internal investigation into certain activities at our China and Singapore offices to determine whether certain import/export and sales documentation activities were improper and in violation of the U.S. Foreign Corrupt Practices Act ("FCPA") and other applicable laws and certain Company policies. We voluntarily notified and are fully cooperating with the SEC and the U.S. Department of Justice ("DOJ") of the internal investigation. On May 1, 2017, the Company received a subpoena from the SEC for documents relating to the internal investigation. Following the conclusion of the Audit Committee's internal investigation, the Company voluntarily reported the relevant findings of the investigation to the China and Singapore authorities and is fully cooperating. During the three and nine months ended September 30, 2018, we recorded $0.3 million and $0.9 million, respectively, of expenses relating to the internal investigation and the SEC subpoena, including expenses of outside legal counsel and forensic accountants, compared to $0.7 million and $2.3 million, respectively, for the three and nine months ended September 30, 2017. We are currently unable to predict what actions the SEC, DOJ, or other governmental agencies (including China and Singapore authorities) might take, or what the likely outcome of any such actions might be, or estimate the range of reasonably possible fines or penalties, which may be material. The SEC, DOJ, and other governmental authorities have a broad range of civil and criminal sanctions, and the imposition of sanctions, fines or remedial measures could have a material adverse effect on the Company’s business, prospects, reputation, financial condition, liquidity, results of operations or cash flows.
