Governmental Investigations The Company is subject to regulation by national, state and local government agencies in the United States and other countries in which it operates.

On October 19, 2017, the Company received a notice of investigation and subpoena to produce documents from the Division of Enforcement of the SEC. The subpoena sought information related to an employee terminated as part of a restructuring and certain matters involving the Company’s policies and accounting practices related to revenue recognition and restructuring activities, as well as related financial reporting, disclosure and compliance matters, since January 1, 2013. The subpoena also sought information concerning, among other things, the Company’s previously identified material weakness in internal controls over the accounting for income taxes, related financial reporting matters and certain payments for non-employee travel expenses. On April 25, 2019, the Staff notified the Company that it had concluded its investigation and, based on the information received to date, does not intend to recommend an enforcement action by the SEC against the Company. Additionally, the Audit Committee of the Company’s Board of Directors, with the assistance of outside counsel, conducted an internal investigation into practices of certain business partners in China and into the conduct of former employees of the Bruker Optics division in China which raised questions of compliance with laws, including the U.S. Foreign Corrupt Practices Act, and/or compliance with the Company’s business policies and code of conduct. The Audit Committee has concluded its internal investigation. As of March 31, 2019 and December 31, 2018, no material accruals have been recorded for potential contingencies related to these matters. Letters of Credit and Guarantees At March 31, 2019 and December 31, 2018, the Company had bank guarantees of $132.4 million and $138.3 million, respectively, related primarily to customer advances.

These guarantees affect the availability of the Company’s lines of credit.
