This paper examines the purpose and function of major retirement savings instruments, including defined benefit plans, defined contribution plans, and simplified employee pension (SEP) plans. It explains the concept of vesting and its importance under ERISA, compares cash balance plans with contribution plans, and evaluates which pension plan structure best serves employees. Drawing on sources from the U.S. Department of Labor and academic researchers, the paper concludes that a combination of life annuities and investment-linked vehicles — such as the 401(k) — offers the most balanced retirement security for workers.
The primary function of a benefit plan or pension plan is to provide income for an individual after he or she retires from work. Some plans extend beyond basic pension income and are referred to as benefit plans. These may include vested termination benefits and disability benefits, and they can take the form of defined contribution or defined benefit plans depending on the option chosen. A defined contribution plan specifies the method and type of benefit that accrues to an employee over time — in other words, it sets a defined amount or contribution that may be fixed. Benefits, by contrast, are additional payments provided under a chosen plan. Benefit plans are protected by federal insurance administered through the Pension Benefit Guaranty Corporation (PBGC) (Winklevoss, 1993).
A defined contribution plan is not based on any specific promised benefit amount at retirement. Under this type of plan, the employee, the employer, or both may make contributions to the employee's individual account, often at a set rate such as a percentage of pay. The contributions are invested, and the ultimate benefit depends on investment gains or losses — meaning the account's value will fluctuate with market performance. Common examples include 401(k) plans, 403(b) plans, and employee stock ownership plans. The primary function of such plans is to maximize the advantage of investment growth and thereby build retirement savings over time (United States Department of Labor, 2012).
Vesting refers to the rate at which an employee's retirement benefits become guaranteed following participation in a plan. Vesting provisions are especially important where there is a highly mobile workforce, as they protect workers who change jobs before reaching traditional retirement age. These provisions are mandatory under the Employee Retirement Income Security Act (ERISA) of 1974. A vesting schedule allows a worker to leave employment before the normal retirement age without losing accrued benefits. Vesting also ensures continued payments to the surviving spouse of an employee who dies while still working and before retirement (Graham, 1998).
