The Federal Trade Commission (the "FTC") has announced revisions to the Hart-Scott-Rodino Antitrust Improvements Act ("HSR Act") thresholds, which will become effective on February 24, 2011. The FTC is required to revise the HSR thresholds annually based upon the change in gross national product. This year's thresholds will increase slightly compared to last year’s thresholds.

Under the HSR Act, when a deal meets the "size of person" and "size of transaction" thresholds, and no exemption from reporting is available, the deal must be reported to the FTC and the U.S. Department of Justice and the parties must wait for a designated period of time before closing the transaction.

Size of Person. The size of person threshold will be met if one party involved in the deal has assets or annual sales totaling $131.9 million or more and one other party involved in the deal has assets or annual sales of at least $13.2 million. Satisfaction of the size of person threshold is not required, however, if the transaction is valued at more than $263.8 million.

Size of Transaction. The size of transaction threshold will be met if the buyer will hold an aggregate amount of stock, non-corporate interests and/or assets of the seller valued at more than $66.0 million as a result of the deal.

The notification thresholds applicable to voting security purchases by minority owners will also increase:

In addition, the thresholds applicable to many exemptions, including those governing foreign acquisitions, will increase. The $500 million threshold applicable to acquisitions of oil and gas reserves, however, will not change.
