HEERLEN, Netherlands and AMSTERDAM, Feb. 14, 2013 /PRNewswire/ -- The Dutch pension fund Stichting Pensioenfonds ABP ("ABP"), together with three co-lead plaintiffs, has reached a settlement with Merck and certain of its current and former officers and directors, whereby Merck will pay $215 million to resolve a five-year-old securities class action against all of the Merck defendants. This settlement is part of a $688 million total settlement that Merck agreed to with plaintiffs in two class actions that were combined for trial: Merck & Co., Inc. Vytorin/Zetia Securities Litigation; and Schering-Plough Corporation/Enhance Securities Litigation. The Merck Vytorin class action, filed in 2008, is pending before Judge Dennis M. Cavanaugh in U.S. District Court for the District of New Jersey. The settlement comes three weeks before a scheduled trial date of March 4. ABP, International Fund Management SA (part of the Deka Bank Group), the Jacksonville Police and Fire Retirement System, and the General Retirement System of the City of Detroit are the four institutional investor lead plaintiffs in the class action. The Merck Vytorin class action settlement covers all investors who purchased Merck stock or options between December 6, 2006 and March 28, 2008. ABP's settlement stems from claims that Merck delayed disclosing for two years results of a clinical trial called ENHANCE - which indicated that Merck's anti-cholesterol drug Vytorin had no statistical advantage in treating atherosclerosis when compared to a generic statin drug, simvastatin. Merck investors alleged that the delay caused a substantial drop in the value of their shares when results of the study were published in 2008. Merck has denied and continues to deny these claims, contending that the company and its officers acted responsibly in connection with the ENHANCE study. The settlement is subject to approval by Judge Cavanaugh.
