What do articles of incorporation serve as?

The articles of incorporation serve as a legal document that establishes the existence of a corporation in the eyes of the state. This document outlines essential aspects such as the corporation's name, purpose, registered agent, and the number of authorized shares. It also provides the framework for managing the organization, including how it will operate and the responsibilities of its directors and officers. This structure is crucial for ensuring compliance with state laws and regulations and delineates the rights and responsibilities of stakeholders.

In contrast, the other options do not accurately capture the primary function of articles of incorporation. While a company's marketing strategy is essential for business development, it falls outside the purview of legal documentation. An informal agreement among business partners lacks the formal legal status and regulatory recognition that articles of incorporation possess, which can lead to complications in establishing a corporate identity. Lastly, a code of ethics pertains to the moral guidelines governing an organization's conduct and does not serve the same legal purpose as articles of incorporation. Thus, the correct answer highlights the legal and structured nature of articles of incorporation in defining ownership and operational protocols within the company.
