During the “go-shop” period, which ended at 11:59 p.m., Eastern Time, on November 1, 2011, the company's representatives solicited superior proposals from third parties. Despite these solicitation efforts, PPD did not receive any alternative acquisition proposals during the “go-shop” period.

The transaction remains subject to antitrust clearance in certain foreign jurisdictions and approval by PPD’s shareholders, as well as other customary closing conditions. PPD has scheduled a special meeting of its shareholders for November 29, 2011, to consider approval of the merger agreement and expects the merger to close in the fourth quarter of 2011.
