History of the Lawsuit

On November 18, 2009, Senior United States District Court Judge John L. Kane appointed Sparer Law Group lead counsel in the securities class-action litigation against the Fund. "We are pleased that the Court ratified the Lead Plaintiff's selection of Sparer Law Group as lead counsel for the class action," said Alan W. Sparer. "Many other firms filed similar actions against the California Fund. The decision by the Court allows investors and witnesses to know where to go to get information about the lawsuit, and whom to contact if they have information that will help us prosecute the action."

Sparer Law Group’s lawsuit against the Fund was consolidated with actions against six other Oppenheimer municipal bond funds before Judge Kane. In April 2010, Oppenheimer filed a motion to dismiss all six actions. Judge Kane denied the motion to dismiss, finding that Plaintiffs had adequately pled viable causes of action against Defendants.

In the summer of 2013, the Plaintiffs in the other six Oppenheimer municipal bond fund cases settled their claims with Oppenheimer for a total of $89.5 million allocated among all six funds. However, the lawsuit against the California Fund has proceeded through discovery, which included the review of millions of pages of documents, the depositions of nearly two dozen Oppenheimer executives, portfolio managers, and risk managers, and the preparation of four expert reports (not including the reports of Defendants’ experts). Sparer Law Group believes that the evidence uncovered thus far confirms the allegations that the Fund failed to adhere to its investment objective and failed to disclose the significant risks taken by the Fund.

In March 2015, Judge Kane granted the motion for class certification. Oppenheimer appealed that order and the Tenth Circuit Court of Appeals sent the motion back to Judge Kane for further findings. The parties have since provided supplemental briefing and in July 2015 the Court conducted a two-day evidentiary hearing relating to class certification issues. At the present time, no further decision on class certification has been issued.
