We distribute retained earnings, if any, either in the form of cash or stock dividends. There is no specific formula by which the amount of distribution is determined. The timing and amount of future distributions will depend on our future earnings and financial conditions.

Unit: NTD / Year	2004	2005	2006	2007	2008	2009	2010	2011
Cash Dividend per Share	8.5	10	11	15	19	14	26	20
Stock Dividend per Share	1.8	1	1	0.5	0.1	0.02	0.02	-
Ex-dividend Date	Jul. 29	Augl. 10	Aug. 2	Jul. 25	Jul. 16	Jul. 17	Jul. 27	Jul. 8

In order to expense employee bonus shares from 2008 , the formula is amended as follows :
New Formula：(Applied from 2009)
(Closing share price of the previous day - Cash dividend per share) + (Subscription price per share * Subscription ratio) / (1 + Stock dividend distribution ratio + Subscription ratio)
Notes：Stock dividend distribution ratio = Stock dividend (shares ) / Total outstanding shares Subscription ratio = New shares subscribed / Total outstanding shares
Example：For example, MediaTek's referenced opening share price for Jul. 28, 2010, the ex-dividend day, is calculated as below:
1. Closing share price on Jul. 27, 2010 is NT$ 483.00
2. Cash dividend per share is NT$ 25.9979
3. Stock dividend distribution ratio is 0.2%, based on 2,180,237 shares divided by total 1,090,205,884 outstanding shares
4. Subscription ratio：N/A
5. Ex-dividend share price is (483.00-25.9979) / (1+0.002) = 456.08
　The market picks the nearest price tick, 456.08, as the referenced ex-dividend price.

Note: Dividend and employee bonus shares are allocated based on earnings from the previous year.

Before 2008, Taiwan Corporate Law states that the allocation of bonuses to employees is considered a part of the corporate earnings distribution. Hence, it is an item to be deducted from retained earnings and not an expense item. From January 1, 2008, employee bonuses were estimated based on 25% of net income (excluding the impact of expensing employees' bonuses and the related income tax effect). Estimated amount of employee bonuses were charged to current income as operating expenses. The Company's employee profit sharing expense ratio has been adjusted to 20% of pro forma net income, effective in 2010 (down from 25% in 2008-2009), to strike a balance of shareholders' interest and overall compensation competitiveness for talents. Based on the outcome, the Board determines how the year's shareholder dividend and employee profit sharing will be appropriated either in form of stocks or cash. If stock bonuses are resolved for distribution to employees, the number of shares distributed is determined by dividing the amount of bonuses by the closing price (after considering the effect of cash and stock dividends) of the shares on the day preceding the meeting.

MediaTek's distributed income in 2009:

MediaTek decided to appropriate total employee bonuses of NT$12,226,536,227, of which 30% was in stock (NT$3,667,960,868 representing 7,485,481 shares) and 70% was in cash (NT$8,558,575,359).
