Pension obligations are one of those topics that separates candidates who have surface-level technical knowledge from those who truly understand the nuances of valuation. Most aspiring investment bankers can explain the basics of enterprise value vs. equity value, but pensions add a layer of complexity that frequently comes up in interviews, particularly for candidates applying to groups that cover industries with large legacy pension plans — such as industrials, airlines, automotive, and utilities.
In this guide, we will cover what pension obligations are, how they appear on the financial statements, whether they should be treated as debt-like items in the enterprise value bridge, and how interviewers test this topic. If you are preparing for investment banking interviews, understanding pensions will give you an edge over candidates who only know the standard technical questions.
Types of Pension Plans
Before diving into the valuation implications, it is important to understand the two main types of employer-sponsored pension plans:
Defined Contribution Plans
In a defined contribution plan (such as a 401(k) in the United States), the employer contributes a set amount to an employee’s retirement account, but the employee bears the investment risk. The employer’s obligation is limited to making the agreed-upon contributions. These plans do not create ongoing liabilities on the balance sheet because the employer’s obligation ends once the contribution is made.
From a valuation perspective, defined contribution plans are straightforward — the annual contributions are an operating expense, and there is no balance sheet liability to worry about.
Defined Benefit Plans
Defined benefit plans are where things get interesting for valuation. In a defined benefit plan, the employer promises to pay retirees a specific benefit amount (usually based on salary history and years of service) for the rest of their lives. The employer bears the investment risk. This creates a long-term liability on the company’s balance sheet — the projected benefit obligation (PBO) — which represents the present value of all future pension payments the company expects to make.
Most defined benefit plans also have associated pension assets — a pool of investments (stocks, bonds, real estate, etc.) that the company has set aside to fund future pension payments. The difference between the PBO and the fair value of pension assets is the plan’s funded status.
Understanding Funded Status
The funded status of a pension plan is the key number for valuation purposes:
- Overfunded plan: Fair value of plan assets > PBO. The company has more assets set aside than it needs to cover future pension obligations. This creates a net pension asset on the balance sheet.
- Underfunded plan: PBO > Fair value of plan assets. The company has a shortfall, meaning it will need to contribute additional cash in the future to meet its pension promises. This creates a net pension liability on the balance sheet.
Most large, legacy defined benefit plans in the United States are underfunded to some degree, though funded status has improved in recent years as higher interest rates have reduced the present value of pension obligations. You can find the funded status disclosed in the pension footnotes of a company’s 10-K filing.
Should Pension Obligations Be Included in Enterprise Value?
This is the central valuation question, and it is one of the most common ways interviewers test this topic. The equity value bridge to enterprise value starts with equity value and adds debt, preferred stock, and minority interest, then subtracts cash and cash equivalents. The question is: where do pension obligations fit in?
The Argument for Including Unfunded Pensions in Enterprise Value
The most common and technically sound approach is to treat the unfunded pension obligation (i.e., the net pension liability) as a debt-like item that gets added in the enterprise value bridge. The logic is as follows:
- An unfunded pension obligation represents a future cash obligation that the company must pay, similar to debt.
- Like debt, pension obligations are a claim on the company’s assets that sits above equity holders in priority.
- If you are calculating enterprise value to compare companies on a capital-structure-neutral basis, you need to capture all debt-like claims, including pensions.
- Ignoring underfunded pensions would make companies with large pension deficits appear cheaper than they actually are when using EV-based multiples.
Under this approach, you would add the net underfunded pension amount to enterprise value. If a company has a net pension asset (overfunded plan), you would subtract it, similar to how you subtract excess cash.
The Argument Against Including Pensions in Enterprise Value
Some practitioners argue that pension obligations should not be included in enterprise value because:
- Pension obligations are operating in nature — they result from employing workers, not from financing decisions.
- Pension expense is already reflected in EBITDA (through service cost and, in some treatments, other pension costs), so including the pension liability in EV would be mixing an operating item with capital structure items.
- The assumptions underlying the PBO (discount rate, expected return on assets, mortality rates) are highly subjective, making the liability less comparable across companies than traditional debt.
Best Practice
In most investment banking contexts, the underfunded pension obligation is treated as a debt-like item and added to enterprise value. This is the approach you should use as your default in interviews unless specifically told otherwise. However, you should be aware of the nuances and be able to discuss both sides if asked. The key is consistency — if you include pensions in EV, you need to make sure the EBITDA or cash flow metric you are using in the denominator of your valuation multiple is calculated in a way that is consistent with that treatment.
How Pension Costs Flow Through the Income Statement
Pension accounting on the income statement can be confusing because the total pension cost is broken into several components:
- Service cost: The increase in the PBO due to employees earning another year of benefits. This is considered an operating expense and is included above operating income.
- Interest cost: The increase in the PBO due to the passage of time (the unwinding of the discount). This is analogous to interest on debt.
- Expected return on plan assets: The expected investment return on the pension fund’s assets. This offsets the interest cost and service cost.
- Amortization of actuarial gains/losses: Changes in actuarial assumptions that are amortized into income over time.
Under current U.S. GAAP, only service cost is included in operating income. The remaining components (interest cost, expected return on assets, and amortization) are presented below operating income, typically in a line item called “other pension cost” or “non-service pension cost.” This distinction matters for modeling because it affects how you calculate EBITDA and operating income.
Pension Obligations in M&A
Pension obligations play a significant role in M&A transactions, particularly when acquiring companies with large defined benefit plans. Here are the key considerations:
- Due diligence: Buyers carefully analyze the target’s pension funded status, actuarial assumptions, and future contribution requirements. An underfunded pension can represent a significant hidden cost.
- Purchase price adjustments: The pension deficit is often treated as a debt-like item in purchase price negotiations, effectively reducing the price the buyer is willing to pay for the equity.
- Change of control provisions: Some pension plans have provisions that are triggered by a change of control, potentially accelerating funding requirements.
- PBGC considerations: The Pension Benefit Guaranty Corporation (PBGC) in the United States insures defined benefit plans and may impose additional requirements or constraints in M&A transactions involving underfunded plans.
Common Interview Questions on Pension Obligations
“How do pension obligations affect enterprise value?”
An unfunded pension obligation is treated as a debt-like item and added to enterprise value in the equity-to-enterprise value bridge. If the pension plan is overfunded, the net pension asset would be subtracted from enterprise value, similar to excess cash. The rationale is that an underfunded pension represents a future claim on the company’s cash flows, similar to debt.
“A company has a pension obligation of $500 million and pension assets of $350 million. How does this affect enterprise value?”
The plan is underfunded by $150 million ($500M obligation minus $350M in assets). You would add $150 million to enterprise value as a debt-like item. You should also check whether this net pension liability is already captured in the company’s reported debt figures or if it needs to be added separately — in most cases, it is disclosed separately in the pension footnotes and needs to be added to the EV bridge.
“What industries are most affected by pension obligations?”
Industries with long operating histories and historically unionized workforces tend to have the largest pension obligations. These include airlines, automotive manufacturers, steel and heavy industrials, utilities, and some large consumer goods companies. Many of these companies established defined benefit plans decades ago when they were the norm, and they continue to carry significant legacy obligations.
Key Assumptions in Pension Valuation
When analyzing pension obligations, it is important to understand the key actuarial assumptions that drive the PBO calculation:
- Discount rate: The rate used to calculate the present value of future pension payments. A lower discount rate increases the PBO; a higher discount rate decreases it. The discount rate is typically based on high-quality corporate bond yields.
- Expected return on plan assets: The assumed long-term return on the pension fund’s investments. A higher assumed return reduces net pension expense. If actual returns fall short, the plan becomes more underfunded.
- Salary growth rate: For plans where benefits are based on final average salary, the assumed rate of salary increases affects the PBO.
- Mortality assumptions: How long retirees are expected to live directly affects the total expected payments.
These assumptions can significantly affect the reported funded status. When comparing companies with large pension plans, it is important to check whether they are using similar assumptions. A company that uses an aggressive (high) discount rate may appear better funded than it actually is.
The Bottom Line
Pension obligations are a nuanced topic that demonstrates your ability to think beyond the standard valuation framework. For most interview purposes, remember that underfunded pension obligations are treated as debt-like items in the enterprise value bridge, understand how pension costs flow through the income statement, and be prepared to discuss why pensions matter in M&A due diligence.
