In October 2012, certain alleged shareholders of the Company filed putative class and derivative actions on behalf of the Company against the members of its Board of Directors and certain entities associated with MSPEA. Three cases were brought in the Third Judicial District Court for Salt Lake County, Utah, which have been deemed related and are pending consolidation under the caption In re Feihe International Shareholder Litigation . Three cases were brought in the Superior Court of the State of California for Los Angeles County, which have been deemed related and are pending consolidation under the caption In re Feihe International, Inc. Shareholder Litigation . The plaintiffs in both the Utah and California cases have alleged breach of fiduciary duties and aiding and abetting in connection with the Going Private Proposal. The plaintiffs in both the Utah and California cases have requested rescission of the Going Private Proposal, to the extent implemented, an award of unspecified damages to the Company, certain other equitable and injunctive relief, and an award of plaintiffs' costs and disbursements, including legal fees. Although the Company is unable to predict the final outcome of these proceedings, the Company does not believe that the final results will have a material effect on its consolidated financial condition, results or operations, or cash flows.
