Introduction
Family businesses represent the backbone of the Brazilian economy. According to data from the Brazilian Institute of Geography and Statistics (IBGE, 2023), approximately 65% of the national Gross Domestic Product (GDP) is generated by family-controlled companies, which account for about 75% of formal employment in the country. However, the mortality rate of these companies is alarming: only 30% manage to transition to the second generation, and merely 5% reach the third generation (Sebrae, 2024).
Corporate governance emerges as the main instrument to reverse this scenario. The implementation of formal governance structures allows separating the interests of family, ownership, and management, creating mechanisms of control, transparency, and professionalization that significantly increase the chances of perpetuating the family business.
Specific Challenges of Family Businesses
Family businesses face unique challenges that distinguish them from other organizations. The main one is the overlap between the family, ownership, and management systems, often represented by the Three Circles Model developed by Tagiuri and Davis (1996). Without established governance, business decisions are influenced by family dynamics, emotional conflicts, and wealth expectations not always aligned with business interests.
Among the most common challenges are: (a) difficulty separating personal and business assets, exposing the company to unnecessary financial risks; (b) resistance to management professionalization, with family members occupying key positions without proper qualifications; (c) lack of succession planning, generating conflicts in the transition between generations; and (d) absence of conflict resolution mechanisms, which can lead to paralysis of strategic decisions and even dissolution of the company (Gersick et al., 2017).
Corporate Governance Structures
Corporate governance in family businesses must be built on four fundamental pillars, as recommended by the Brazilian Institute of Corporate Governance (IBGC, 2023):
1. Board of Directors. The board of directors is the collegiate body responsible for strategic guidance and oversight of executive management. In family businesses, the inclusion of independent directors is recommended, bringing external and impartial perspectives to strategic discussions.
2. Family Council. The family council is the forum where family members discuss topics related to family values, wealth education, and expectations regarding the business. It is the appropriate space to debate policies for entry and exit of family members from the company, as well as to align expectations on dividends and reinvestments.
3. Family Protocol (Family Agreement). The family protocol is a document that establishes the rules of relationship between the family and the business, including criteria for family members entering the company and management, dividend policy, share sale rules, mediation mechanisms, and succession guidelines (Lodi, 2022).
4. Advisory Committees. Audit, finance, human resources, and sustainability committees can be established to address specific topics, always with the participation of qualified professionals.
Succession Planning and Asset Protection
Succession planning is one of the most important instruments for perpetuating the family business. In Brazil, succession planning can be carried out through different legal structures, the most common being: (a) donation with usufruct reservation, allowing gradual transfer of ownership to successors while maintaining the donor's right to usufruct; (b) creation of family holding companies, concentrating family assets in one or more entities, facilitating management and succession; and (c) will drafting, establishing the destination of assets after the owner's death.
The family holding company has emerged as the most efficient structure for Brazilian family businesses. When properly structured, the holding company allows concentrating asset management, reducing probate costs, optimizing tax burden in succession planning, and protecting assets against business risks (Oliveira & Martins, 2023).
Management Professionalization
Management professionalization is the process of transitioning from an administration based on family ties to management based on technical competencies and professional merit. This process does not mean excluding family members from management, but rather establishing clear criteria for their participation, including minimum qualifications, prior professional experience outside the company, and periodic performance evaluation.
A study conducted by the Family Firm Institute (FFI, 2024) demonstrated that family businesses implementing formal management professionalization programs show 27% higher revenue growth compared to those maintaining exclusively family management models.
Conclusion
Corporate governance is not a luxury reserved for large corporations, but a strategic necessity for family businesses of all sizes aiming for longevity. The implementation of formal governance structures — board of directors, family council, family protocol, and succession planning — allows separating the interests of family, ownership, and management, creating the necessary conditions for the company to thrive across generations with financial health and family harmony.
