PMSI augments our physician targeting capabilities in Europe, and enhances global market research through Scott-Levin." 2 Under terms of the agreement, PMSI shareholders will receive .2800 shares of Cognizant common stock per PMSI share, as payment to shareholders of $180 million. The number of Cognizant shares received is subject to a collar adjustment based on the price of Cognizant shares during a period prior to the closing of the transaction. PMSI currently has approximately 12.4 million shares outstanding. The transaction has been independently authorized by the Cognizant and PMSI boards of directors, and is subject to approval by PMSI shareholders. The transaction will be accounted for under purchase accounting and is expected to be tax-free, and is projected to close in the second quarter of 1998, subject to regulatory approval.
