In this paper we analyzed the importance of ethical and conduct codes in implementing the compliance programs in an organization. We presented the assumptions that were the basis for the forming of ethic and compliance programs, as well as their evolution in the last decades. In the first part of this paper we highlighted the legislation that outlined principles required for organizations to implement their compliance programs and business ethics. This legislation came as a response to corporate scandals relating to bribery, fraud and corruption in the 70s, and governments of the affected countries were forced to react in order to prevent, detect inappropriate behaviour, as well as improve corporate behaviour. After coming into force of the Federal Law "The Foreign Corrupt Practices Act of 1977" (FCPA, 1977), there was an increase in the number of codes of conduct and corporate involvement in adopting a conduct supported by consumers and stakeholders and to redefine the standards and values, to create a new image corresponding to the new market requirements. In the Guidelines 2002 basic principles are set out in order to efficiently implement a compliance and ethics program in business. The case study was materialized in the analysis of ethics and compliance codes, and the method used for implementing them in three Romanian companies. Analyzing the three ethics and conduct codes, we can conclude that the most important factor to successfully implement ethics and compliance within an organization is "tone from the top". CEO conduct is one that has a direct effect on members of the organization. Furthermore, we followed capturing developments in the rules governing the international business ethics and evaluated the legal framework regulating these issues. The primary aim was to assess how rules are implemented throughout business ethics compliance programs developed at company level and to identify ways to promote - at an organizational level β the culture of ethical business and compliance
