Compensation Committee regulatory

"Chairman of the Compensation 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.

Audit Committee regulatory

"member of the 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.
