Select a publicly traded firm of your choice that enjoys a large shareholder base. What challenges may this firm have encountered (or is likely to encounter) in terms of (a) incorporating ethics into financial management practices, and (b) maintaining/sustaining ethical practices in the face of internal or external (market) pressures? Frame your response relative to the financial manager's fiduciary duty to maximize shareholder's wealth.

I am choosing Pinnacle Bank or Arizona Federal Credit Union
