Other Postemployment Benefits (OPEB) valuations

The Health Care Authority (HCA) administers PEBB plan benefits. For medical insurance coverage, the HCA has two claims pools: one covering employees and non-Medicare eligible retirees, and the other covering retirees enrolled in Medicare Parts A and B. PEBB plan benefits provide two different subsidies for retirees: an explicit subsidy and an implicit subsidy.

The explicit subsidy, permitted under the Revised Code of Washington (RCW) 41.05.085, is a capped dollar amount that lowers the monthly premium paid by members and their spouses over the age of 65 enrolled in Medicare Parts A and B. The explicit subsidy is the lesser of 50 percent of the monthly premium and the set dollar amount adopted by the Legislature. The following graph displays the historical maximum monthly explicit subsidy as of the 2022 PEBB OPEB report. This graph is for informational purposes and will not be updated with every valuation. Please see the most recent valuation for more recent explicit subsidy values and assumptions for growth in this subsidy.

The implicit subsidy, set up under RCW 41.05.022, is more complex because it is not a direct reduction in a member’s premium. Claims experience for active employees and non-Medicare eligible retirees are pooled when determining non-Medicare premiums. Therefore, these retired members pay a premium based on a pool of members that, on average, are younger and healthier. There is an implicit subsidy from the employee group since the premiums paid by the non-Medicare retirees are lower than they would have been if the retirees were insured separately. The subsidies are valued using the difference between the age-based claims costs and the premiums paid by these retirees. For dental benefits, there is only one claim pool. All retirees, both Medicare and non-Medicare eligible, are pooled with active employees to determine a blended premium. Retirees pay the full premium so the only subsidy that exists is an implicit subsidy, since the premium retirees pay is lower due to being pooled with active employees.

Governmental Accounting Standards Board Statement No. 75 (GASB 75) requires employers to disclose key financial measures for the plan, including the Total OPEB Liability (TOL), OPEB expense, and benefit payments (or employer contributions).

GASB 75 requires the use of the Entry Age Normal (EAN) actuarial cost method to measure the Actuarial Accrued Liability (AAL). The AAL under the EAN cost method is also referred to as TOL in GASB 75. In addition, the discount rate for OPEB plans without a dedicated trust fund is based on a 20-year municipal bond index, which means the discount rate will fluctuate from year-to-year.

In Washington State, the implicit and explicit subsidies are funded on a pay-as-you-go basis, meaning that PEBB employers pay these costs as they occur.

It is important to look at the projections of the expected future subsidy payments (or benefit payments) in order to determine if the payments are manageable. Projections allow policy makers to determine the best funding policy for the state and their constituents while providing investors and stakeholders knowledge of what lies ahead.

The following graph illustrates expected state subsidy payments for current hires as well as future new hires. This graph is for educational purposes and may not include the most recent actuarial valuation results. We intend to update this graph with the next PEBB OPEB Experience Study.

The above graph is for illustrative purposes only, so we made simplifying assumptions for these future hires. We prepared new hire cohorts for this graph based on the Public Employees’ Retirement System (PERS) Plan 2/3 New Hire Profiles and assumed PERS growth. Further, we assumed that all members participate in the UMP medical and dental plans.

The projected subsidy payments could be higher or lower, based on actual growth of the explicit subsidy.

The medical benefit, set up under the Revised Code of Washington (RCW) 41.26.150(1), provides free medical and LTC coverage for LEOFF 1 retirees. When a LEOFF 1 member retires, the employer they retire from is responsible for the full cost of postemployment medical benefits. Individual local disability boards administer the LEOFF 1 medical plan. Each board may interpret the language “necessary medical services” differently.

Summary of Minimum Medical Services

Each local government disability board has the discretionary power to determine which costs they will reimburse or not. However, there is a list of minimum services for which they must reimburse the retiree, as defined in RCW 41.26.030(20). These services are outlined below:

• Hospital board and room not to exceed semi-private, unless condition requires otherwise.
• Hospital services, other than board and room.
• Licensed physicians or surgeons.
• Licensed osteopaths.
• Licensed chiropractors.
• Charges of a registered graduate nurse.
• Physician-prescribed drugs and medications.
• Diagnostic X-ray and laboratory examinations.
• X-ray, radium, and radioactive isotopes therapy.
• Anesthesia and oxygen.
• Rental of durable medical and surgical equipment.
• Artificial limbs and eyes; and casts, splints, and trusses.
• Professional ambulance services to transport to or from a hospital.
• Dental charges resulting from accidental injury to the teeth if treatment starts within 90 days.
• Nursing home confinement or hospital extended care facility.
• Physical therapy by a registered physical therapist.
• Blood transfusions.
• Licensed optometrists.

The list above represents a summary of minimum services and does not determine the overall medical benefits for each individual. Ultimately, each disability board determines which services to reimburse.

Summary of Long-Term Care Coverage

There are also two types of LTC covered under LEOFF 1 OPEB:

1. Institutional – Care provided in a nursing home or wing of a hospital designed to provide nursing care services or an assisted living facility, including:
   1. Skilled – includes nursing and rehabilitation services that can only be performed by skilled medical personnel; must be under orders of a physician and provided on a 24-hour basis.
   2. Intermediate – includes continuous treatment not meeting all the requirements for skilled care.
   3. Custodial – includes assistance in carrying out daily living activities.
2. Non-Institutional – Includes all home health and adult day-care services.

Funding Policy

The LEOFF 1 medical expenses are funded on a pay-as-you-go basis, meaning that LEOFF 1 employers pay these costs as they are incurred. This generally means today’s taxpayers of cities with retired LEOFF 1 members are paying for benefits that were earned in the past. This funding policy is in conflict with the principle of intergenerational equity, where the goal is to fund a member’s benefit over their working lifetime.

Insurance

Insurance allows the LEOFF 1 employers to control the volatility in annual medical service costs. For example, if a LEOFF 1 employer only has one retiree, the ongoing annual costs will vary widely depending on whether that retiree had a relatively healthy year or, for example, entered LTC. When many employers group together in an insurance pool, they will be able to pay a steadier annual amount to offset medical service costs. The Legislature has approved this practice by codifying it in RCW 41.26.150(4).

LEOFF 1 employers may participate in insurance pools established by certain associations, and most LEOFF 1 employers have joined their respective association’s medical plans. The remaining LEOFF 1 employers that choose not to join have several other options. Some obtain coverage through union health and welfare plans (e.g., Teamsters), while others contract through individual insurance providers or self-insure.

An actuary performs an actuarial valuation to estimate what benefits will be paid throughout the future lifetimes of current members, and then discounts those payments back to the present. The result is the Present Value of Future Benefits (PVFB). For example, a dollar amount today, equal to the PVFB, could be invested during plan members’ lifetimes to pay all expected future benefits when the members are eligible. In this case, the benefit payments are the necessary medical service costs for the LEOFF 1 retirees.

When performing an actuarial valuation, an actuary needs inputs such as participant data, benefit provisions, and assumptions. Participant data includes age, membership service, employment status, etc. Benefit provisions include the structure of the benefits that the members receive—for example, the retiree medical benefits paid by employers. Assumptions include the discount rate, healthcare trends, decrement rates, medical and LTC costs, etc.

An actuary analyzes these inputs using an actuarial cost method. The chosen cost method allocates costs between past and future plan membership service before retirement. Distinct actuarial cost methods produce different results since each method allocates costs differently. The Entry Age Normal (EAN) cost method required under the Governmental Accounting Standards Board Statement No. 75 (GASB 75) allocates plan benefits so they are earned, or accrued, as a level percentage of pay throughout an employee’s working lifetime.
