Incremental funding ratio

Incremental Funding Ratio

The incremental funding ratio is a specific metric, typically used within the context of pension finance, that assesses the change in a pension plan's funding status relative to new obligations accrued over a period. Unlike the traditional funded ratio, which provides a snapshot of a plan's total assets against its total liabilities at a given point in time, the incremental funding ratio focuses on the marginal funding of newly accrued benefits. This ratio provides insights into whether a plan's current contributions and investment returns are sufficient to cover the cost of benefits earned by employees during a specific period. This focus on incremental changes helps stakeholders understand the ongoing financial health and sustainability of defined benefit plans.

History and Origin

The concept of evaluating the financial health of pension plans has evolved significantly, particularly with the growth of private pension plans in the United States and the subsequent need for regulation. Early private pensions, such as the one established by American Express in 1875, were often discretionary and lacked formal funding requirements¹⁶, ¹⁷, ¹⁸. As pension plans became more widespread in the mid-20th century, issues of underfunding and mismanagement emerged, notably highlighted by the closure of the Studebaker automobile company in the early 1960s, where many workers lost their promised pension benefits¹⁵.

This sparked a demand for greater oversight, culminating in the enactment of the Employee Retirement Income Security Act of 1974 (ERISA). ERISA established minimum standards for private-sector employee benefits plans, including requirements for funding, participation, vesting, and fiduciary duties¹⁴. It also created the Pension Benefit Guaranty Corporation (PBGC) to insure defined benefit plans and protect participants' benefits¹², ¹³.

While ERISA and subsequent legislation, like the Pension Protection Act of 2006, focused on overall funding levels and solvency, the nuances of incremental funding have become more critical in actuarial science and financial reporting. Accounting standards, particularly those outlined in the Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) Topic 715, "Compensation—Retirement Benefits," require companies to recognize the funded status of their pension plans on their balance sheet. ⁹, ¹⁰, ¹¹The incremental funding ratio, while not a directly mandated reporting metric, arises from the need for pension plan sponsors and actuaries to understand the ongoing sustainability of funding practices relative to new benefit accruals, especially in dynamic economic environments.

Key Takeaways

• The incremental funding ratio measures the extent to which new pension obligations are covered by new contributions and investment returns.
• It provides a forward-looking perspective on the sustainability of a pension plan's funding.
• This ratio helps assess the adequacy of current funding policies in relation to the accrual of fresh liabilities.
• A ratio below 1 indicates that the plan is not fully covering newly earned benefits, potentially leading to a growing unfunded liability over time.
• It complements the traditional funded ratio by offering a more granular view of ongoing funding dynamics.

Formula and Calculation

The Incremental Funding Ratio is calculated by comparing the total increase in plan assets during a period to the increase in the projected benefit obligation (PBO) over the same period, adjusted for benefits paid out.

The formula can be expressed as:

Where:

• Contributions: The employer and employee contributions made to the pension plan during the period.
• Actual Investment Returns: The actual gains or losses on the plan's assets during the period. This figure is crucial and is heavily influenced by market volatility.
• Benefits Paid: The benefits disbursed to retirees and beneficiaries during the period.
• Change in Projected Benefit Obligation (excluding interest cost): The increase in the present value of future benefit payments attributable to new employee service during the period, adjusted for actuarial gains and losses but excluding the interest cost component of the PBO change (which reflects the passage of time). This component essentially represents the cost of newly accrued benefits.

Interpreting the Incremental Funding Ratio

Interpreting the incremental funding ratio provides critical insights into the ongoing financial management of a pension plan. A ratio greater than 1 indicates that the assets flowing into the plan (from contributions and investment gains) are more than sufficient to cover the cost of new benefits earned by employees during the period. This suggests a healthy funding trajectory and can contribute to improving the overall funded ratio.

Conversely, an incremental funding ratio of less than 1 signals that the plan is not generating or receiving enough assets to fully fund the new liabilities incurred by employee service. If this trend persists, it can lead to a deepening of the unfunded liability, placing greater strain on the employer to make up the deficit in future periods. A consistent ratio below 1 highlights a potential structural issue in the plan's funding policy or a significant shortfall in investment returns. Analyzing this ratio helps identify whether the plan's actuarial assumptions about future contributions and returns are realistic in covering new benefit accruals.

Hypothetical Example

Consider "Horizon Corp.," a company with a defined benefit plan for its employees.

At the beginning of the year, Horizon Corp.'s pension plan had a Projected Benefit Obligation (PBO) of $500 million.
During the year:

• Employer contributions to the plan: $20 million
• Actual investment returns on plan assets: $15 million (after expenses)
• Benefits paid out to retirees: $30 million
• The increase in PBO due to new employee service (excluding interest cost and actuarial assumptions changes): $25 million

To calculate the Incremental Funding Ratio:

Numerator (Assets Inflow - Benefits Outflow):
Contributions + Actual Investment Returns - Benefits Paid = $20 million + $15 million - $30 million = $5 million

Denominator (Cost of New Benefits):
Change in Projected Benefit Obligation (excluding interest cost) = $25 million

Incremental Funding Ratio = $\frac{$5 \text{ million}}{$25 \text{ million}} = 0.20$

In this hypothetical example, Horizon Corp.'s incremental funding ratio is 0.20. This indicates that for every dollar of new benefit liability accrued by employees during the year, only $0.20 was covered by contributions and investment gains after paying out benefits. This suggests a significant underfunding of new obligations, which, if unaddressed, will lead to a worsening of the plan's overall funded status over time.

Practical Applications

The incremental funding ratio is a vital tool for various stakeholders in pension finance:

• Pension Plan Sponsors: Companies use this ratio to evaluate the effectiveness of their ongoing funding strategies. A low incremental funding ratio might prompt a review of contribution policies, investment allocations, or even the plan design itself to ensure long-term sustainability. It is a critical component of sound risk management.
• Actuaries: Actuaries regularly calculate this ratio as part of their assessment of a pension plan's financial health. It helps them provide advice to plan sponsors on required contributions and the long-term viability of benefit promises.
• Regulators and Oversight Bodies: While not always a direct regulatory metric, the underlying principles inform regulatory bodies like the PBGC, which monitors the financial health of covered defined benefit plans. The PBGC's solvency and ability to protect benefits are tied to the aggregate funding health of the plans it insures.
• Investors and Analysts: For publicly traded companies, the incremental funding ratio, derived from detailed financial reporting in annual reports and proxy statements, can offer insights into the company's financial discipline regarding its liabilities. A consistently low ratio could signal future cash flow pressures as the company may need to increase contributions. Market volatility can significantly impact a plan's actual investment returns, making the incremental funding ratio a dynamic indicator to monitor.
  ⁷, ⁸* Policymakers: Governments, at both federal and state levels, track the aggregate health of public pension systems. While the exact "incremental funding ratio" may not be a standard reported metric for public plans, the concept is embedded in discussions about the adequacy of contributions to cover newly earned benefits, a persistent challenge for many public plans.

Limitations and Criticisms

While the incremental funding ratio offers valuable insights, it also has limitations and faces criticisms:

• Sensitivity to Volatility: The ratio is highly sensitive to actual investment returns, which can be volatile. A single period of poor market performance can dramatically lower the incremental funding ratio, even if the underlying funding strategy is sound for the long term. ³, ⁴This can lead to short-term alarm that may not reflect long-term trends.
• Complexity of Actuarial Assumptions: The "Change in Projected Benefit Obligation" component relies on complex actuarial assumptions, such as salary growth, mortality rates, and employee turnover. Changes in these assumptions, or their underlying methodologies, can significantly alter the denominator, making period-over-period comparisons challenging and potentially masking real funding issues.
  ²* Exclusion of Interest Cost: By excluding interest cost on the PBO from the denominator, the ratio focuses purely on the cost of new service. However, the interest cost is a significant ongoing component of pension expense and liability growth, and its exclusion might give an incomplete picture of total funding requirements in a given period.
• Focus on a Single Period: Like many ratio analyses, the incremental funding ratio presents a snapshot or a single period's performance. It may not capture the cumulative effect of past funding decisions or long-term strategic adjustments. A series of analyses over several periods is necessary for a comprehensive understanding.
• Data Availability and Comparability: For external analysis, granular data required to calculate this specific ratio might not always be readily available in publicly disclosed financial statements. Furthermore, variations in reporting and actuarial practices among different entities can make cross-company or cross-plan comparisons difficult.

Incremental Funding Ratio vs. Funded Ratio

The incremental funding ratio and the funded ratio are both crucial metrics in pension finance, but they serve different purposes and provide distinct perspectives on a pension plan's financial health.

While the funded ratio tells you how much of the total pie is currently covered, the incremental funding ratio tells you if you're baking enough new pie to cover the new slices being promised. Both are essential for a complete understanding of a pension plan's financial standing and future prospects.

FAQs

What is the primary purpose of the incremental funding ratio?

The primary purpose of the incremental funding ratio is to assess whether a pension plan is adequately funding the new benefits that employees earn each period. It provides a measure of the current period's financial sustainability for new liabilities.

How does market volatility affect the incremental funding ratio?

Market volatility can significantly impact the "actual investment returns" component of the incremental funding ratio. Strong returns will increase the numerator, potentially improving the ratio, while poor returns will decrease it, indicating a shortfall in covering new obligations, even with consistent contributions.

Is the incremental funding ratio a legally mandated metric?

No, the incremental funding ratio is typically an analytical metric used by actuaries and plan sponsors rather than a directly mandated legal or financial reporting requirement like the overall funded ratio for pension plans. However, the components used to calculate it are derived from information that must be reported under accounting standards like FASB ASC Topic 715.
¹

Can a pension plan have a high funded ratio but a low incremental funding ratio?

Yes, it is possible. A pension plan might have a high overall funded ratio due to strong historical investment performance or large past contributions. However, if current contributions and investment returns are insufficient to cover newly accruing benefits, the incremental funding ratio could be low, signaling future funding challenges despite a currently healthy overall status.

What are the implications of a persistently low incremental funding ratio?

A persistently low incremental funding ratio indicates that a pension plan is not keeping pace with the cost of new benefits being earned by its employees. This can lead to a growing unfunded liability over time, potentially requiring the employer to make larger contributions in the future, which could impact the company's financial statements and cash flow.
