  • The Filing Fee Information and Current Thresholds pages have been updated with the 2019 HSR thresholds. (04/04/19)

  • Many HSR practitioners have requested that we announce when an Informal Interpretation has been superseded in whole or in part. To that end, we have created a new page to list informal interpretations that no longer represent the position of the PNO. The new page will list superseded interpretations starting from January 1, 2019, onward. See the new page here: Superseded Informal Interpretations. (03/19/19)

  • The Commission has amended the Fiscal Year 2017 Hart-Scott-Rodino Annual Report to add two non-HSR matters that were inadvertently left out of the report when it was published in 2018. This brings the total number of merger enforcement actions in fiscal year 2017 to 23, with 15 final consent orders. The corrected 40th report can be found on the HSR Annual Reports page. (03/11/19)

  • Check out our new blog post: “Control no longer controlling for HSR reporting of not-for-profit combinations”.

  • Over the summer, the Premerger Notification Office held three brown bag meetings with experienced HSR practitioners. The meetings were an opportunity for the HSR bar to meet staff, share comments regarding the HSR process, and address any concerns or “big picture” policies. Over 50 attorneys from various law firms attended one of the three 60-90 minute sessions held in May, June, and July at the FTC’s Constitution Center. A summary of the brown bags, including the issues discussed and important guidance, has been added to the HSR Resources page and is now available here.

  • The Medicare Act filing instructions have been updated with DOJ’s current address. (08/07/18)

  • IMPORTANT NOTICE: Given the current high volume of HSR filings, it is even more important than usual to note when your filing is related to other filings as part of a larger transaction – for instance, a main transaction with a backside filing or a buyer making two acquisitions at the same time.

    When you have related filings, please include in the cover letter and Item 3(a): THIS FILING SHOULD BE PROCESSED WITH RELATED FILINGS MADE BY [insert relevant other parties]. This will assist the PNO in the efficient and timely processing of your transaction. Thank you. (08/03/18)

  • IMPORTANT NOTICE: The Premerger Notification Office no longer accepts checks at the Constitution Center. This is true whether delivered by messenger or by mail. Please DO NOT send checks to the PNO. The Commission strongly discourages check payments, but if checks are used to pay filing fees, they must be sent to Financial Operations at the FTC HQ. See the Filing Fee Information page for full instructions. (07/26/18)
