| c. | Retained earnings and dividend policy
In accordance with the amendments to the Company Act in May 2015, the recipients of dividends and bonuses are limited to shareholders and do not include employees. The consequential amendments to the Company’s Articles of Incorporation was resolved at the Company’s annual shareholders’ meeting. For information about the accrual basis of the employees’ compensation and remuneration to directors and the actual appropriations, please refer to employee benefits expense under profit before income tax in Note 24(g). The amended Articles of Incorporation of ASE Inc. (the “Articles”) in June 2016 provides that annual net income shall be distributed in the following order:
| 1) | Replenishment of deficits;
| 2) | 10.0% as legal reserve;
| 3) | Special reserve appropriated or reversed in accordance with laws or regulations set forth by the authorities concerned;
| 4) | Addition or deduction of realized gains or losses on equity instruments at fair value through other comprehensive income;
The Company is currently in the mature growth stage. To meet the capital needs for business development now and in the future and satisfy the shareholders’ demand for cash inflows, the Company shall use residual dividend policy to distribute dividends, of which the cash dividend is not lower than 30% of the total dividend distribution, with the remainder to be distributed in stock. A distribution plan is also to be made by the board of directors and passed for resolution in the shareholders’ meeting. Appropriation of earnings to legal reserve shall be made until the legal reserve equals the Company’s share capital. Legal reserve may be used to offset deficits. If the Company has no deficit and the legal reserve has exceeded 25% of the Company’s share capital, the excess may be transferred to capital or distributed in cash. Under Rule No. 1010012865 and Rule No. 1010047490 issued by the FSC and the directive titled “Questions and Answers for Special Reserves Appropriated Following Adoption of IFRSs”, the Company should appropriate to or reverse a special reserve. Expect for non-ROC resident shareholders, all shareholders receiving the dividends are allowed a tax credit equal to their proportionate share of the income tax paid by the Company. The appropriations of earnings for 2015 and 2016 resolved at the Company’s annual shareholders’ meetings in June 2016 and June 2017, respectively, were as follows:
