TSMC Common Share Ex-dividend Date June 8th
Dividends include a cash dividend of NT$2.99950486 for each common share
and a stock distribution of 4.99917480 shares per 1,000 common shares
Hsinchu, Taiwan, R.O.C. — May 25, 2007 — TSMC (TAIEX: 2330, NYSE: TSM) today announced that the ex-dividend date for TSMC common shares shall be June 8, 2007. The dividends include a cash dividend of NT$2.99950486 for each common share and a stock distribution of 4.99917480 shares per 1,000 common shares.
The above-mentioned dividend was calculated based on the total amount of profits to be distributed and capital surplus to be capitalized, as approved by the Company’s shareholder meeting on May 7, 2007, and the actual number of common shares outstanding on the record date for said dividend distribution. As a result of the employee stock options exercised between the day the Company’s board proposed said dividend distribution, and the record date of the distribution, the number of common shares outstanding has increased slightly, resulting in a miniscule difference in the per-share dividends from the per-share amount proposed by the Company’s board on February 6, 2007.
