(1) As regards the dividends to be distributed to individual shareholders and securities investment funds of the Company’s A shares, according to the Notice on Differentiated Individual Income Tax Policies Applicable to the Stock Dividends Distributed by Listed Companies (Cai Shui [2015] No. 101) and the Notice on Issues Related to the Implementation of the Differentiated Individual Income Tax Policy on Dividends and Bonuses Distributed by Listed Companies (Cai Shui [2012] No.85), the Company will not withhold the income tax for the time being when distributing dividends, and the cash dividends to be distributed will be RMB0.40 per share.

When any individual shareholder or securities investment fund transfers its shares after the equity rights registration date, China Clearing Shanghai Branch will calculate the amount of tax payable based on the duration of holding of such shares, and a securities company or other stock depository agency shall deduct the amount of tax payable from the individual investor’s fund account and transfer to China Clearing Shanghai Branch, which will transfer the deducted amount of tax to the Company within the first five working days of the following month, and the Company will then file tax returns with and pay the tax to competent tax authority within the statutory filing period in the month it receives the tax payment. If the term of holding of such shares is less than one month (including one month), 100% of the dividend income of such investor shall be calculated as the taxable income and the income tax shall be levied on such taxable income at a rate of 20%; if the term of holding of such shares is between one month and one year (including one year), 50% of the dividend income of such investor shall be calculated as the taxable income for the time being and the income tax shall be levied on such taxable income at a rate of 10%; and if the term of holding of such shares is longer than one year, the dividend income of such investor shall be exempted from the individual income tax for the time being.
