Final answer:
To satisfy the 50/40 test, the retirement plan must cover a minimum number of eligible employees. In this case, with 100 eligible employees, the plan must cover 50 eligible employees.
Step-by-step explanation:
The 50/40 test is a requirement for defined benefit pension plans under the Employee Retirement Income Security Act (ERISA). It stipulates that at least 50% of the non-highly compensated employees of a company must participate in the plan.
The other requirement is that at least 40% of the non-highly compensated employees must also be participating in the plan regardless of the participation of highly compensated employees.
In this case, there are 100 eligible employees working for the company. To satisfy the 50/40 test, the minimum number of employees that the retirement plan must cover is calculated as follows:
50% of 100 eligible employees = 50 eligible employees
40% of 100 eligible employees = 40 eligible employees
Therefore, the retirement plan must cover 50 eligible employees to satisfy the 50/40 test.
