Litigation description	"Going private" proposal and related litigations In October 2012, the Company's Board of Directors received a preliminary, non-binding proposal from Mr. Leng You-Bin, its Chairman and Chief Executive Officer, and an affiliate of Morgan Stanley Private Equity Asia, Inc. ("MSPEA"), the private equity arm of Morgan Stanley, to acquire all of the outstanding shares of common stock of the Company not currently owned by Mr. LengYou-Bin, MSPEA and their respective affiliates in a going private transaction for $7.40 per share in cash, subject to certain conditions (the "Going Private Proposal"). The Company's Board of Directors formed a Special Committee of independent directors (the "Special Committee") to consider the Going Private Proposal, which retained a financial advisor and legal counsel to assist it in this process. 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 consolidated 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. In March 2013, the Company entered into an Agreement and Plan of Merger (the "Merger Agreement") with Diamond Infant Formula Holding Limited ("Holdco"), Platinum Infant Formula Holding Limited, and a wholly owned subsidiary of Holdco ("Parent"), and Infant Formula Merger Sub Holding Inc., a wholly owned subsidiary of Parent ("Merger Sub"), which would effectuate the Going Private Proposal. Pursuant to the terms and subject to the conditions of the Merger Agreement, Merger Sub would merge with and into the Company with the Company surviving as a wholly-owned subsidiary of Parent and a wholly-owned indirect subsidiary of Holdco (the "Merger"). In connection with and at the effective time of the Merger, each share of the Company's common stock that is outstanding immediately prior to the effective time of the Merger will be cancelled in consideration for the right to receive $7.40 in cash without interest, except for those shares beneficially owned by Mr. Leng You-Bin, Mr. Liu Sheng-Hui, Mr. Liu Hua, Holdco, Parent, Merger Sub, the Company or any subsidiary immediately prior to the effective time of the Merger, which shares will be cancelled for no consideration at the effective time of the Merger, subject to applicable dissenters rights. If the Merger closes pursuant to the Merger Agreement, the Company would cease to be listed on the NYSE or a public reporting company in the U.S. The Merger Agreement is subject to closing conditions, including certain shareholder approvals, and there can be no assurance that this or any other transaction will be approved or consummated.
