Model Business Corporation Act Principles
Model Business Corporation Act (MBCA) Principles:
The Model Business Corporation Act (MBCA) is a model statute developed by the American Bar Association to provide uniform corporate law principles across U.S. states. While each state enacts its own version, the MBCA serves as a guiding framework for corporate governance, shareholder rights, director duties, and corporate compliance. Corporations adopting MBCA principles are expected to uphold transparency, fiduciary duties, and accountability.
1. Core Principles of the MBCA

- Shareholders’ liability is generally limited to their investment.
- Board of Directors Governance
- Directors manage corporate affairs unless delegated to officers.
- Fiduciary duties include care and loyalty.
- Shareholder Rights
- Rights to vote, inspect records, receive dividends, and participate in mergers or fundamental changes.
- Protections for minority shareholders, including appraisal rights.
