What does the TSM Form 3 filing by VP Liaw Yung-Haw report?

The Form 3 reports Liaw Yung-Haw’s existing ownership in TSM common shares. It lists direct and indirect holdings, including shares held personally, under an Employee Stock Purchase Plan trust, a Long-Term Incentive bonus plan trust, and Hsing Yu Investment Co., Ltd.

How many TSM shares does Liaw Yung-Haw hold directly according to this Form 3?

The filing shows direct ownership of 463,054 TSM common shares. This direct position is separate from additional indirect holdings reported through an Employee Stock Purchase Plan trust, a Long-Term Incentive plan trust, and Hsing Yu Investment Co., Ltd., which are listed as indirect positions.

What indirect TSM shareholdings are disclosed for Liaw Yung-Haw in this Form 3?

The filing discloses indirect holdings via three entities. These are an Employee Stock Purchase Plan trust, a Long-Term Incentive bonus plan trust, and Hsing Yu Investment Co., Ltd., each reported with its own common share balance and classified as indirect ownership.

Does the TSM Form 3 show any recent share purchases or sales by Liaw Yung-Haw?

The Form 3 functions as an initial ownership report, not a trade record. The entries are labeled as holdings with unknown transaction codes, indicating disclosure of existing positions rather than clearly identified new purchases or sales of TSM common shares.

The ESPP and LTI trusts hold TSM shares linked to employee compensation plans.
