Which situation typically results in the greatest number of required pension disclosures?

Participation in an agent multiple-employer defined benefit plan typically results in the greatest number of required pension disclosures. This is because agent multiple-employer plans are structured in such a way that each participating employer maintains separate pension accounts and is responsible for funding their own obligations. As a result, these plans require extensive disclosures regarding the financial position, actuarial assumptions, and funding status for each participating employer, in addition to general information about the plan as a whole.

These disclosures are necessary to ensure transparency and provide stakeholders with sufficient information to understand the risks associated with the pension obligations. Such detailed reporting is essential for clarity on how the plan operates and how employees of each employer are affected, thus necessitating a comprehensive approach to disclosure.

Cost-sharing multiple-employer defined benefit plans, while still requiring disclosures, do not need the same level of detail for each employer since the funding and liabilities are pooled. Defined contribution plans and insured plans also generally entail fewer disclosure requirements compared to agent multiple-employer plans, as they involve less complexity regarding each employer's specific obligations.
