Litigation

On April 20, 2021, an indirect subsidiary of HFSC, which was acquired in June 2020, received a grand jury subpoena from the United States District Court for the Southern District of California requiring the production of documents for the time period December 1, 2017 through February 4, 2019 related to the subsidiary's employment of a certain individual and its performance of work on certain Navy vessels during that time period. The Company is cooperating with the investigation. The Company has completed its production of documents responsive to the subpoena, although the Company has a continuing obligation to produce such documents should any be located. At this early stage in the investigation, the Company cannot predict the outcome of the investigation or when the investigation will ultimately be resolved; nor can the Company reasonably estimate the possible range of loss or impact to its business, if any, that may result from this matter.

With the exception of the matter noted above, the Company is involved in various legal actions arising in the normal course of business. Based upon the Company’s and its legal counsel’s evaluations of any claims or assessments, management is of the opinion that the outcome of these matters will not have a material adverse effect on the Company’s results of operations, financial position or cash flows.
