6 terms

independent director financial

"Ms. Chien, an independent director on the Board of Directors of FST Corp."

An independent director is a member of a company's board of directors who is not involved in the company's day-to-day operations and has no significant relationships with the company that could influence their judgment. Their role is to provide unbiased oversight and ensure the company is managed in the best interests of all shareholders. This helps build trust and confidence among investors by promoting transparency and accountability.

Audit Committee financial

"appointed Mr. Chang to serve as a member of the Company’s Audit Committee"

A company's audit committee is a small group of board members who act like independent inspectors for the firm's finances, overseeing how financial reports are prepared, monitoring internal controls, and managing the relationship with external auditors. Investors care because a strong audit committee reduces the risk of accounting errors, fraud, or misleading statements, making financial statements more trustworthy and helping protect shareholder value.

Compensation Committee financial

"appointed Mr. Chang to serve as a member of the Company’s Audit Committee, Compensation Committee, and Nominations Committee"

A compensation committee is a group within a company's leadership responsible for setting and reviewing how much top executives and employees are paid, including salaries, bonuses, and benefits. It matters to investors because fair and effective pay decisions can influence a company's performance, leadership motivation, and overall governance, helping ensure that the company’s management is aligned with shareholders’ interests.

Nominations Committee financial

"appointed Mr. Chang to serve as a member of the Company’s Audit Committee, Compensation Committee, and Nominations Committee"

indemnity agreement financial

"The Company also entered into an indemnity agreement with Mr. Chang in the same form"

related party transactions financial

"there are no related party transactions between Mr. Chang and the Company that would require disclosure"

Transactions between a company and people or entities that have close ties to it—such as executives, board members, major shareholders, family members, or related companies—where the parties are not independent. These deals matter to investors because they can create conflicts of interest or hide favorable terms that distort a company’s true profits and risks; think of it like a business buying or selling to a family member instead of using the open market, which can lead to biased prices or undisclosed obligations.
