On February 15, 2019, the Federal Trade Commission (FTC) announced the annual threshold adjustments for premerger filings under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (15 U.S.C. § 18a) (HSR). The FTC revises the thresholds annually based on the change in gross national product. The revised HSR thresholds will apply to all transactions that close on or after the effective date, and the effective date will be in late March.
