LONG-TERM EQUITY INVESTMENTS IN JIAOZUO WANFANG AND YINXING ENERGY

Pursuant to the stipulations of significant influence on the investee in Article 5 of the Accounting Standards of Business Enterprises No.2 - Long-term Equity Investments issued by the Ministry of Finance of the PRC in 2006, significant influence is the power to participate in the financial and operating policy decisions of an enterprise, but to fail to control or joint control the formulation of such policies together with other parties. Where the investor can exercise significant influence over the investee, the investee is its associate. Article 8 stipulates that "where the investor has long-term equity investments which has joint control or significant influence on the investee, the long-term equity investments should be calculated with equity method in accordance with the requirements of Articles 9 to 13 in this Standard". After the aforementioned non-public offering of shares of Jiaozuo Wanfang in 2013, the Company held 17.75% equity interests thereof. Although the Company lost its control thereon, it was still the largest shareholder of Jiaozuo Wanfang with significant influence on the vote at general meetings. Meanwhile, in accordance with the articles of association of Jiaozuo Wanfang, which were revised after its non-public offering of shares, the Company could nominate five candidates of non-independent directors. Therefore, the Company is of the view that the Company continued to have significant influence on Jiaozuo Wanfang after the aforementioned non-public offering of shares of Jiaozuo Wanfang. Accordingly, the Company used equity method to calculate its equity investments on Jiaozuo Wanfang, which is an associate thereof.

Pursuant to the stipulations of execution of control on the investee in Article 5 of the Accounting Standards of Business Enterprises No.2 - Long-term Equity Investments issued by the Ministry of Finance of the PRC in 2006, control means that the Group has the power to decide an enterprise's financial and operating policies, pursuant to which, the Group can obtain benefits from its operating activities. Where the investor can exercise control over the investee, the investee is a subsidiary of the investor, which shall be deemed as a subsidiary and included in the consolidated financial statements of the investor. Therefore, the cost method required by the Standard shall be used to calculate the long-term equity investments of the investor on its subsidiary, with the equity method to make some adjustments when preparing consolidated financial statements. Ningxia Energy, a subsidiary of the Company, held 28.02% equity interests of Yinxing Energy, and the Company indirectly held 19.84% equity interests of Yinxing Energy through Ningxia Energy. Ningxia Energy is the largest shareholder of Yinxing Energy with the right to appoint five non-independent shareholders out of six in Yinxing Energy. As the balance of equity holdings in Yinxing Energy is disperse and other shareholders have not organized their interests and cannot easily organize themselves in such a way that they exercise more votes than the minority shareholder, the board of directors of the Company is of the view that Ningxia Energy has substantial control over Yinxing Energy, and Yingxing Energy shall be deemed as a subsidiary and included in the consolidated financial statements of Ningxia Energy.

The above-mentioned five major subsidiaries are all mainly engaged in producing and selling primary aluminum products.
