Employee Stock Purchase Plan financial
"Common Shares purchased by the administrator of the issuer's Employee Stock Purchase Plan ("ESPP") on behalf of the filer"
An employee stock purchase plan is a company program that lets workers buy shares through small payroll deductions, often at a discount to the market price and after a set offering period. Think of it like a workplace savings plan that turns into ownership: it encourages employees to share in the company’s success and can create predictable buying or selling of stock that investors watch because it affects supply, demand and employee incentives.

FAQ

What did TSM VP Lu Lee-Chung do in this Form 4 filing?

TSM vice president Lu Lee-Chung acquired 65 common shares through the Employee Stock Purchase Plan. The purchase was made by the plan administrator under predetermined terms, reflecting routine participation in the company’s employee share purchase program rather than a large discretionary market trade.

How many TSM shares did Lu Lee-Chung buy and at what price?

Lu Lee-Chung acquired 65 TSM common shares at an average price of $57.87 per share. The price is translated from an average purchase price of NT$1,837.2789, using an exchange rate of NT$31.748 to US$1, as disclosed in the filing footnotes.

Is the TSM VP’s share purchase a direct or indirect holding?

The 65 shares were purchased indirectly through an Employee Stock Purchase Plan trust. The filing notes these are common shares bought by the ESPP administrator on behalf of Lu, who is credited with indirect ownership via the plan rather than a direct brokerage account purchase.

What are Lu Lee-Chung’s total direct TSM share holdings after this transaction?

After the reported transactions, Lu directly owns 276,716 TSM common shares. This direct position is separate from additional indirect holdings via the Employee Stock Purchase Plan trust, a Long-Term Incentive plan trust, and shares held by a spouse, which together increase overall exposure.

What indirect TSM share holdings does Lu Lee-Chung report besides the ESPP trust?

Beyond the ESPP trust, Lu reports 7,036 TSM common shares held through a Long-Term Incentive bonus plan trust and 15,000 common shares held by a spouse. These positions are reported as indirect ownership interests, supplementing Lu’s substantial directly held stake in the company.

Is this TSM insider transaction part of a pre-set employee plan?

Yes. Footnotes state the common shares were purchased by the Employee Stock Purchase Plan administrator on Lu’s behalf under terms predetermined by the issuer. This indicates a structured employee share purchase arrangement rather than ad hoc open-market buying driven by short-term share price views.
