An MET can be beneficial to both employers and their employees. Participating in an MET can lower costs associated with forming and managing a broad benefit plan that follows the Employee Retirement Income Security Act of 1974 (ERISA). Employers can use multiple employer plans to work together and combine their resources, which can save these employers money.  Employers also get the benefit of aggregating risk across the total trust to provide greater predictability and rate stabilization.

METs make it possible for small businesses to offer their employees large employer benefits typically only available to large companies. The lower fees for benefits also help businesses avoid lawsuits for allowing plan participants to pay excessive investment fees. Avoiding lawsuits is another way small businesses can lower their operating costs. Another advantage of METs is that they lower an individual employer’s fiduciary risks and responsibilities because the plan sponsor tends to be in charge of administrative and fiduciary roles.
