Item 8.01. Other Events.
On October 18, 2017, NxStage Medical, Inc. (“NxStage”) and Fresenius Medical Care Holdings, Inc. (“Fresenius”) each received a request for additional information and documentary material (also known as a “Second Request”) from the United States Federal Trade Commission (“FTC”) pursuant to the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, ("HSR Act") in connection with Fresenius’s proposed acquisition of NxStage.
The effect of the Second Request is to extend the waiting period imposed by the HSR Act until 30 days after Fresenius and NxStage have substantially complied with the request, unless that period is terminated sooner by the FTC. By agreement with the FTC, the parties may voluntarily extend the time for closing beyond the expiration of the HSR Act waiting period.
