How a defined benefit plan works
A defined benefit plan is a type of retirement plan in which the company promises to pay a specified benefit to certain eligible employees upon their retirement. The benefit amount is based on a specific formula that considers various factors such as the employee’s W2 salary history, years of company service, and age at retirement. Unlike defined contribution plans where the contributions are known, but the benefits are uncertain, defined benefit plans provide a predictable retirement income stream.
To fund the promised benefits, the employer or plan sponsor contributes money into a dedicated pension fund. These contributions are invested over time with the goal of generating returns and growing the fund’s assets. The invested funds are managed by professional investment managers, who make strategic investment decisions to balance risk and return.

When employees reach retirement age, they become eligible to receive a regular stream of income from the plan, usually in the form of a monthly pension payment. The amount of the pension is predetermined based on the plan’s formula, taking into account the employee’s earnings history and years of service. The plan continues to make payments to the retiree for the duration of their retirement, providing a stable and predictable income source throughout their post-employment years.
Who bears the risk in a defined benefit plan?
In a defined benefit plan, the employer typically bears the investment risk. The employer promises to provide a specific benefit to employees upon their retirement, which is typically based on factors such as salary and years of service. The employer is responsible for funding the plan and ensuring that there are sufficient assets to meet the future benefit obligations.
One of the key risks in a defined benefit plan is the investment risk. The employer is responsible for investing the plan’s assets with the goal of generating returns to fund the promised benefits. If the investments underperform or the plan’s assets do not grow sufficiently, the employer may need to contribute additional funds to meet the benefit obligations.

This is different from a defined contribution plan, such as a 401(k) plan, where the investment risk is generally borne by the individual employee. In a defined contribution plan, the employee contributes a portion of their salary into an individual account, and the investment returns and eventual benefit amount depend on the performance of the employee’s investments.
It’s important to note that the specific allocation of risk can vary depending on the terms of the plan and any agreements between the employer and employees. Additionally, legal and regulatory requirements may also impact the allocation of risk in certain situations.
What are the risks in a defined benefit plan?
A defined benefit plan is a type of pension plan in which an employer promises to provide a specified retirement benefit to employees upon their retirement. While these plans offer significant advantages to employees, they also come with certain risks. Here are some of the risks associated with defined benefit plans:
- Investment Risk: One of the primary risks in a defined benefit plan lies in the investments made to fund the promised benefits. The plan sponsor, typically an employer or pension fund, must invest contributions in order to generate sufficient returns to meet future obligations. If the investments underperform or experience losses, it can create a shortfall between the plan’s assets and liabilities, potentially requiring additional funding from the employer.
- Longevity Risk: Defined benefit plans are designed to provide benefits for the entire duration of an employee’s retirement, regardless of how long they live. If retirees live longer than expected, the plan may need to make payments for a longer period than initially anticipated, increasing the cost of providing benefits and potentially straining the plan’s financial health.
- Funding Risk: The obligation to fund the promised benefits rests with the plan sponsor. If the employer fails to contribute enough funds to meet the plan’s obligations, it can lead to a funding shortfall. In such cases, the plan sponsor may be required to make additional contributions to cover the deficit, which can place a financial burden on the employer.
- Regulatory and Legislative Risk: Changes in laws and regulations governing pension plans can have significant implications for defined benefit plans. Alterations in funding requirements, accounting standards, taxation, or other regulations can impact the financial stability and cost of maintaining the plan.
- Economic and Market Risk: Defined benefit plans are subject to various economic and market risks. Factors such as inflation, interest rate fluctuations, and economic downturns can affect the plan’s investment performance, funding status, and the ability to meet benefit obligations.
- Demographic Risk: The demographic characteristics of plan participants can introduce risk. If a plan has a high proportion of older employees or retirees compared to active workers, it can strain the plan’s finances as there are fewer contributions coming in to support the benefit payments.
- Employer Risk: The financial health and stability of the plan sponsor or employer also impact the risks associated with a defined benefit plan. If the employer faces financial difficulties or bankruptcy, it may be unable to meet its pension obligations, potentially resulting in reduced or even lost benefits for plan participants.

It’s important to note that the specific risks can vary depending on the details of the plan and the circumstances surrounding it. Employers, plan sponsors, and participants should carefully evaluate these risks and take appropriate measures to mitigate them, such as prudent investment strategies, regular plan monitoring, and ongoing adjustments to funding policies.

Final thoughts
In conclusion, while defined benefit plans offer valuable retirement benefits to employees, they are not without risks. Investment risk, longevity risk, funding risk, regulatory and legislative risk, economic and market risk, demographic risk, and employer risk are some of the key risks associated with these plans.
The performance of plan investments, changes in demographics, economic conditions, and regulations can all impact the financial health and sustainability of a defined benefit plan. Employers and plan sponsors must carefully manage these risks, regularly assess the plan’s funding status, make prudent investment decisions, and adapt to changing circumstances to ensure the plan’s ability to fulfill its obligations to retirees.
For employees participating in defined benefit plans, it is crucial to understand the potential risks involved and monitor the financial stability of their employers. Being aware of the risks can help individuals make informed decisions regarding their retirement planning and consider diversifying their retirement savings through additional vehicles such as individual retirement accounts (IRAs) or other retirement savings plans.
Overall, a balanced approach that combines the benefits of a defined benefit plan with other retirement savings strategies can help individuals mitigate risks and achieve a secure financial future in retirement.
