A plan sponsor in a multiemployer plan is usually the plan’s joint board of trustees, and when no board or other entity is designated, the plan administrator serves as the sponsor.
A Plan Sponsor (Multiemployer Plan) plays a central role in managing and overseeing multiemployer retirement plans, especially those covered under collective bargaining agreements. In simple terms, this is the entity responsible for establishing, maintaining, and ensuring the smooth operation of the plan. For most multiemployer plans, that sponsor is the joint board of trustees, which represents both labor and management. When no such board exists, the plan administrator steps in to fulfill this role.
This concept is important for anyone participating in a multiemployer pension plan, including workers, employers, and union representatives. Understanding who the plan sponsor is helps clarify who oversees the plan, who makes major decisions, and who ensures compliance with federal rules.
Understanding the Role of a Plan Sponsor in a Multiemployer Plan
A Plan Sponsor (Multiemployer Plan) is responsible for setting up and managing a retirement plan that covers employees from multiple employers within the same industry or labor group. These plans are common in sectors such as construction, transportation, hospitality, and entertainment.
Unlike single-employer plans, which have one sponsoring company, multiemployer plans rely on a joint governing body — the board of trustees. This board typically includes equal representation from unions and employers, ensuring shared oversight and balanced decision-making.
When no board of trustees has been assigned, federal rules dictate that the plan administrator automatically becomes the plan sponsor.
Key Responsibilities of a Plan Sponsor (Multiemployer Plan)
The plan sponsor has several important duties, including:
-
Establishing the plan’s rules and structure, including eligibility guidelines and benefit formulas.
-
Ensuring compliance with ERISA, PBGC requirements, and tax laws.
-
Overseeing plan funding, including employer contributions negotiated under collective bargaining agreements.
-
Hiring and supervising service providers, such as actuaries, investment managers, and legal counsel.
-
Communicating with participants about their rights, benefits, and any plan changes.
In a multiemployer setting, the shared governance structure ensures that both union members and employers have a voice in these decisions.
Why the Identity of the Plan Sponsor Matters
Knowing who the plan sponsor is can help participants understand:
-
Who makes decisions about the plan’s investments and funding.
-
Who is responsible for maintaining plan documents and ensuring regulatory compliance.
-
Who participants can contact with questions about benefits or plan operations.
For workers and retirees, this clarity provides confidence that the plan is being managed responsibly. For employers, it ensures consistency in how retirement benefits are handled across different job sites or companies within the same union group.
Example to Make It Clear
Imagine a union representing electricians across several companies. These employers all contribute to a shared pension plan for their workers. The plan is governed by a joint board of trustees — half from the union and half from the employers. This board is the plan sponsor.
If, for any reason, the plan did not have an established board of trustees, the plan administrator — the individual or committee responsible for daily plan operations — would automatically become the plan sponsor.
Final Summary
A Plan Sponsor (Multiemployer Plan) is typically the plan’s joint board of trustees, representing both labor and management. If no board or designated entity exists, the plan administrator serves as the sponsor instead. This sponsor is responsible for establishing, overseeing, and maintaining the pension plan, ensuring compliance, and protecting participants’ benefits. Understanding the plan sponsor helps participants know who manages their retirement plan and where to turn for accurate information.
