Code of Ethics and Business Conduct regulatory
"approved an amended and restated Code of Ethics and Business Conduct"
A code of ethics and business conduct is a company’s written rulebook that explains the expected behavior of its leaders and employees, covering honesty, conflicts of interest, legal compliance and fair treatment. For investors it matters because a strong, enforced code helps reduce the risk of fraud, legal fines and reputational damage—much like house rules that keep a shared home orderly and predictable, protecting the value of the investment.
