Introductory Note

This Amendment No. 7 to Schedule 13D amends and supplements the statement on Schedule 13D filed with the Securities and Exchange Commission on July 25, 2005, as previously amended and supplemented by amendments to Schedule 13D filed on January 11, 2008, April 30, 2008, January 15, 2016, February 1, 2016, March 10, 2016 and November 18, 2016 (as so amended, the “Original Schedule 13D”), jointly by Beams Power Investment Limited (“Beams”), Mr. Liang Zhang (“Mr. Zhang”) and Ms. Xiuqing Meng (“Ms. Meng”, and together with Beams and Mr. Zhang, the “Reporting Persons”). Except as amended and supplemented herein, the information set forth in the Original Schedule 13D remains unchanged. Capitalized terms used herein have meanings as assigned thereto in the Original Schedule 13D unless defined herein.

Item 4. Purpose of Transaction.

Item 4 of the Original Schedule 13D is hereby amended and supplemented by adding the following at the end thereof:

On April 28, 2017, at 11:00 a.m., Beijing time, a special meeting of stockholders of the Company was held at the Synutra International Building, 106 Dong Lu Yuan, Tongzhou District, Beijing 101101, China. At the special meeting, the Company’s stockholders voted in favor of the proposal to approve the agreement and plan of merger, dated as of November 17, 2016 (the “Merger Agreement”), by and among the Company, Beams and Beams Power Merger Sub Limited (“Merger Sub”), providing for the merger of Merger Sub with and into the Company with the Company surviving the merger as a wholly owned subsidiary of Beams (the “Merger”).

On May 15, 2017, pursuant to the terms of the Merger Agreement, Merger Sub was merged with and into the Company, with the Company as the surviving corporation in the Merger and a wholly owned subsidiary of Beams. Upon consummation of the Merger, each issued and outstanding Share, other than the Excluded Shares and the Dissenting Shares, was converted automatically into the right to receive US$6.05 in cash without interest.

Upon consummation of the Merger, the Company became a wholly owned subsidiary of Parent and the separate corporate existence of Merger Sub ceased. As a result of the Merger, the Shares ceased to trade on the NASDAQ Global Select Market (“NASDAQ”) following the close of trading on May 15, 2017 and became eligible for delisting from NASDAQ and termination of registration pursuant to Rules 12g-4(a)(1) and 12h-3(b)(1)(i) of the Exchange Act.

As a result of these transactions, as of May 15, 2017, none of the Reporting Persons beneficially owns any Shares.

Item 5. Interest in Securities of the Issuer.

Item 5 of the Original Schedule 13D is hereby amended and restated in its entirety as follows:

(a), (b) As of the date hereof, the Reporting Persons do not beneficially own any Shares or have any voting power or dispositive power over any Shares.

(c) Except as set forth in Item 4 of this statement, none of the Reporting Persons has effected any transactions in the Shares during the last sixty days.

(d) Not Applicable.

(e) May 15, 2017.
