Overview of Public Pension Plan Amortization Policies

Introduction

A pension plan’s amortization policy is a central feature of its funding policy, and the effectiveness of the amortization policy can have significant effects on a pension plan’s long-term cost. An amortization policy is defined as the rules and processes that determine the length of time and the structure of payments required to systematically eliminate a funding shortfall, known as the unfunded actuarial accrued liability (UAAL). The UAAL, or unfunded liability, is the difference between a plan’s actuarial value of assets and its liabilities, which are the accumulated value of benefits earned by plan participants.

Nearly every public pension plan has an unfunded liability; some plans have an actuarial surplus, which also is referred to as a negative unfunded liability. As financial obligations, public pension unfunded liabilities sometimes are likened to debt. As with other government obligations, unfunded liabilities typically are amortized, or paid, in a systematic manner over a period of time.

Amortization policies are characterized by several factors described in this brief. NASRA compiled data on elements of public pension plan amortization policies of 104 statewide and 20 locally administered public pension plans as of the latest fiscal year date for which this information was broadly available, generally FY 2020. Collectively the plans in this sample represent nearly $4.0 trillion in assets and nearly $1.5 trillion in unfunded liabilities to be amortized. For purposes of comparing amortization policies, this paper distinguishes plans by the basis of employer contributions: variable or fixed.

What's New at NASRA: Public Pension Investment Return Assumption Brief Updated

NASRA’s latest update to standing issue briefs, Public Pension Plan Investment Return Assumptions underscores the critical role the investment return assumption plays in the financial health of public pension plans. Of all actuarial assumptions, it has the greatest impact on plan funding levels and cost. This brief traces how a decade of low interest rates and inflation, beginning in 2009, prompted many plans to reduce their long-term expected returns in line with more modest capital market projections. However, since inflation began rising in early 2021, the trend toward lowering return assumptions has largely paused. While reducing a plan’s assumed return can increase both costs and unfunded liabilities, setting this assumption is a careful, thorough process. It draws on expert input from actuaries and investment professionals and is guided by actuarial standards of practice.
