NORCROSS, Ga., and RICHMOND, Va. -- Rock-Tenn Company and MeadWestvaco Corporation announced 10 March 2015 that the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 (HSR Act) with respect to the pending business combination transaction between RockTenn and MWV has expired. The 30-day waiting period is required by the Federal Trade Commission and U.S. Department of Justice as part of the premerger notification program before such a combination transaction can close.

On 6 Feb. 2015, RockTenn and MWV filed the requisite notification and report forms under the HSR Act with the U.S. antitrust authorities. The expiration of the waiting period under the HSR Act satisfies one of the conditions to the closing of the pending business combination transaction, which remains subject to other customary closing conditions, including receipt of stockholder and shareholder approvals, as applicable, and other regulatory approvals.
