OppenheimerFunds Inc. is an American asset management company serving financial advisors, individual investors and institutions.

According to a press release dated April 29, 2009, the Complaint alleges that the Pennsylvania Fund, Oppenheimer Funds and certain of its officers and trustees violated the Securities Act of 1933 and the Investment Company Act of 1940 by departing from the stated investment premise and otherwise injured Fund shareholders. The Pennsylvania Fund is a municipal bond fund yielding interest income exempt from federal and Pennsylvania income taxes. The Complaint alleges that during the Class Period, the Registration Statements and Prospectuses misled investors about the Fund's investment objectives, policies and the underlying risk by characterizing its investments as consistent with preservation of capital. In fact, the Fund lost over 33% of its net asset value ("NAV") in 2008 compared with an average peer group loss of approximately 9.5%. The Complaint alleges that capital preservation was disregarded as the Fund significantly increased exposure through excessively risky strategies not properly disclosed to investors.

Specifically, the overarching principle of capital preservation was compromised by concentrating large positions in low rated bonds, bonds not reviewed by an independent rating agency and by portfolio concentration in high risk securities including, Tobacco Bonds, Dirt Bonds, and Inverse Floaters.

The action regarding Oppenheimer Pennsylvania Municipal Fund is being handled in In Re: Oppenheimer Rochester Funds Group Securities Litigation, Master Docket No. 09-md-02063-JLK-KMT.
