Definition
Unfunded Actuarial Accrued Liability (UAAL) represents the portion of the actuarial accrued liability (AAL) of a pension plan that is not covered by the plan’s assets. Simply put, UAAL is the difference between the liabilities that a pension plan owes to its beneficiaries and the assets it currently has to cover those liabilities.
Formulation
Using financial notation, UAAL can be expressed as:
Types and Special Considerations
- Open UAAL: This method involves amortizing the UAAL over a rolling timeframe, meaning the period is consistently extended.
- Closed UAAL: This approach involves amortizing the UAAL over a set period that decreases each year.
Actuaries must consider various factors when calculating UAAL:
- Interest Rate Assumptions: The assumed rate of return on plan assets.
- Demographic Assumptions: Member longevity and retirement ages.
- Plan Amendments: Changes in the plan benefits that can impact liabilities.
Examples
- State Pension Plan: A state has an AAL of $1 billion and plan assets of $600 million, resulting in UAAL of $400 million.
- Corporate Pension Fund: A corporation’s pension plan has an AAL of $500 million with assets worth $450 million, leading to UAAL of $50 million.
Historical Context
Pension funding issues have been a significant concern since the late 19th and early 20th centuries, as various private and public sector firms began implementing defined benefit plans. The concept of UAAL gained prominence as organizations and governments focused on measuring and managing long-term pension obligations, especially after several high-profile pension shortfalls.
Applicability
Financial Health
UAAL is a critical indicator of the financial health of pension funds. High UAAL suggests potential future funding issues, which could necessitate increased contributions or reduced benefits.
Regulatory Compliance
Governments and regulatory bodies often mandate reporting of UAAL to ensure transparency and accountability in pension fund management.
Comparisons
- Funded Status: This is the ratio of plan assets to the AAL. A funded status below 100% signifies UAAL.
- Pension Obligation Bond (POB): POBs are sometimes issued to cover UAAL, shifting the liability from the pension fund to the government’s broader balance sheet.
Related Terms
- Actuarial Accrued Liability (AAL): AAL refers to the total present value of future pension benefits owed to current employees and retirees.
- Pension Plan Assets: The total investments and contributions held within the pension plan.
- Funded Ratio: The ratio of a pension plan’s assets to its liabilities.
Frequently Asked Questions (FAQs)
What causes UAAL to increase?
UAAL increases can be due to poor investment returns, changes in demographic assumptions, plan benefit enhancements, or not meeting the actuarial assumed rate of return.
How can UAAL be reduced?
UAAL can be reduced by increasing contributions, improving investment returns, altering benefit structures, or issuing Pension Obligation Bonds.
What are the risks associated with high UAAL?
A high UAAL poses risks to plan solvency, potentially leading to benefit cuts, increased contributions from employers and employees, and reputational damage.

Summary
Unfunded Actuarial Accrued Liability (UAAL) is a vital metric used to assess the financial health of pension funds, representing the shortfall between plan liabilities and plan assets. Understanding and managing UAAL is crucial for ensuring the sustainability and reliability of pension plans over the long term.
