Under the R.O.C. relevant laws, the capital surplus generated from donations and the excess of the issuance price over the par value of capital stock (including the stock issued for new capital, mergers and convertible bonds) may be used to offset a deficit; in addition, when the Company has no deficit, such capital surplus may be distributed as cash dividends or stock dividends up to a certain percentage of TSMC’s paid-in capital. The capital surplus from share of changes in equities of subsidiaries and associates and dividend of a claim extinguished by a prescription may be used to offset a deficit; however, when generated from issuance of restricted shares for employees, such capital surplus may not be used for any purpose.
| c. | Retained earnings and dividend policy
TSMC’s Articles of Incorporation provide that, when allocating the net profits for each fiscal year, TSMC shall first offset its losses in previous years and then set aside the following items accordingly:
| 1) | Legal capital reserve at 10% of the profits left over, until the accumulated legal capital reserve equals TSMC’s paid-in capital;
| 2) | Special capital reserve in accordance with relevant laws or regulations or as requested by the authorities in charge;
| 3) | Any balance left over shall be allocated according to the resolution of the shareholders’ meeting.
TSMC’s Articles of Incorporation provide the policy about the profit sharing bonus to employees, please refer to Note 33. TSMC’s Articles of Incorporation also provide that profits of TSMC may be distributed by way of cash dividend and/or stock dividend. However, distribution of earnings shall be made preferably by way of cash dividend. Distribution of earnings may also be made by way of stock dividend, provided that the ratio for stock dividend shall not exceed 50% of the total distribution. Any appropriations of the profits are subject to shareholders’ approval in the following year. The appropriation for legal capital reserve shall be made until the reserve equals the Company’s paid-in capital. The reserve may be used to offset a deficit, or be distributed as dividends in cash or stocks for the portion in excess of 25% of the paid-in capital if the Company incurs no loss. Pursuant to existing regulations, the Company is required to set aside additional special capital reserve equivalent to the net debit balance of the other components of stockholders’ equity, such as the accumulated balance of foreign currency translation reserve, unrealized valuation gain or loss from fair value through other comprehensive income financial assets, unrealized valuation gain or loss from available-for-sale financial assets, gain or loss from changes in fair value of hedging instruments in cash flow hedges, etc. For the subsequent decrease in the deduction amount to stockholders’ equity, any special reserve appropriated may be reversed to the extent that the net debit balance reverses.
