The securities litigation law firm of Brower Piven, A Professional Corporation, announces that a class action lawsuit has been commenced in the United States District Court for the Southern District of New York on behalf of purchasers of The Advisory Board Company (Nasdaq: ABCO) ("Advisory Board" or the "Company") securities during the period between January 21, 2015 and February 23, 2016, inclusive (the "Class Period"). Investors who wish to become proactively involved in the litigation have until October 2, 2017 to seek appointment as lead plaintiff. If you wish to choose counsel to represent you and the class, you must apply to be appointed lead plaintiff and be selected by the Court. The lead plaintiff will direct the litigation and participate in important decisions including whether to accept a settlement for the class in the action. The lead plaintiff will be selected from among applicants claiming the largest loss from investment in Advisory Board securities during the Class Period. Members of the class will be represented by the lead plaintiff and counsel chosen by the lead plaintiff. No class has yet been certified in the above action. The complaint accuses the defendants of violations of the Securities Exchange Act of 1934 by virtue of the defendants' failure to disclose during the Class Period that the Company experienced significant problems with integration resulting from the acquisition of Royall & Company ("Royall") and there were no grounds for increasing the revenue guidance for Royall. According to the complaint, following a February 23, 2016 announcement disclosing the extent of the problems with Royall, the value of Advisory Board declined significantly. If you have suffered a loss in excess of $100,000 from investment in Advisory Board securities purchased on or after January 21, 2015 and held through the revelation of negative information during and/or at the end of the Class Period and would like to learn more about this lawsuit and your ability to participate as a lead plaintiff, without cost or obligation to you, please visit our website at http://www.browerpiven.com/currentsecuritiescases.html.
