It defines stakeholders as those with a claim or interest in a company, distinguishing between primary stakeholders necessary for survival like employees and secondary stakeholders like media. Corporate social responsibility is viewed as a contract with society, while business ethics establishes rules of conduct. Effective corporate citizenship meets economic, legal, ethical and philanthropic responsibilities.
