Enron kept company debt and insider trading hidden through complex organizational partnerships and processes. A cultural change that might have exposed the fraud as it was occurring is: Oa. the use of a mission statement. Ob. the establishment of a whistle-blowing hotline. Oc. the creation of a code of conduct. Od. a greater use of company ceremonies. A purely compliance-based approach to preventing the fall of Enron would likely have failed because: Oa. compliance-oriented corporate cultures never work. Ob. company leaders needed values-based ethical decision making, not more rules and laws. Oc. governments and businesses have no way to enforce compliance with legal standards.
