Two Different Worlds of Defined Benefit Plans
Although both promise a defined monthly check upon retirement, government pensions (federal FERS/CSRS, state employees, public safety, teachers) and corporate pensions (Fortune 500 manufacturers, airlines, legacy telecoms) operate under vastly different legal and economic structures.
1. Cost-of-Living Adjustments (COLA)
The most substantial difference in Net Present Value comes from inflation protection:
- Government Pensions: Typically include an annual compounding COLA indexed to the Consumer Price Index (CPI-W) or a statutory 1.5%–3.0% annual increase.
- Corporate Pensions: Virtually all private sector corporate pensions are fixed nominal annuities with 0% COLA. Over a 25-year retirement, inflation halves the real purchasing power of the corporate check.
2. Backing & Insolvency Protections
- Government Plans: Backed by sovereign taxing power. Even underfunded state plans (such as Illinois or New Jersey) are bound by state constitutional contracts preventing reduction of accrued benefits for active and retired members.
- Corporate Plans: Insured by the Pension Benefit Guaranty Corporation (PBGC). In corporate bankruptcy, the PBGC assumes control of the plan, but statutory guarantee caps (e.g. ~$85,000/year at age 65) can haircut high-earner executive benefits.
