Compensation packages for active workers may include pensions as well as health-care and other similar benefits for those employees after they have completed their active service. Generically, health-care and other benefits are described as other postemployment benefits (OPEB) to distinguish them from pensions.1 Employers are required to recognize the cost of pension benefits as employees earn them, and the Governmental Accounting Standards Board (GASB) has now extended this same requirement to OPEB.2 While pensions have long been funded on an actuarial basis, OPEB plans have not. The change in accounting standards has focused attention on the costs of OPEB, including concerns about rising health-care costs and an aging public-sector workforce. The real issue is not the change in accounting standards for such a funding policy and OPEB, as such, but rather the underlying budgetary and funding challenge that those accounting standards highlight. Meeting this challenge requires government finance officers to ensure that both pension and OPEB are sustainable over the long term - that they are affordable to stakeholders, competitive, and sufficient to meet employee needs, and that they may be reasonably expected to remain so.
GFOA recommends that every state and local government that offers defined benefit pensions and/or OPEB formally adopt a funding policy that provides reasonable assurance that the cost of those benefits will be funded in an equitable and sustainable manner. Such a retirement benefits funding policy would need to incorporate the following principles and objectives:
- Every government employer that offers defined benefit pensions or OPEB should obtain no less than biennially an actuarially determined contribution (ADC) to serve as the basis for its contributions to those respective plans;
- The ADC should be calculated in a manner that fully funds the long-term costs of promised benefits, while balancing the goals of 1) keeping contributions relatively stable and 2) equitably allocating the costs over the employees’ period of active service;
- Every government employer that offers defined benefit pensions or OPEB should make a commitment to fund the full amount of the ADC each period. (For some government employers, a reasonable transition period will be necessary before this objective can be accomplished);
- Every government employer that offers defined benefit pensions or OPEB should demonstrate accountability and transparency by communicating all of the information necessary for assessing the government’s progress toward meeting its pension funding objectives.
These principles and objectives necessarily will affect decisions related to the treatment of three core elements of a comprehensive pension funding policy:
- Actuarial cost method - the technique used to allocate the total present value of future benefits over an employee’s working career (normal cost/service cost).
- Asset smoothing method - the technique used to recognize gains or losses in pension assets over some period of time so as to reduce the effects of market volatility and stabilize contributions.
- Amortization policy - The length of time and the structure selected for increasing or decreasing contributions to systematically eliminate any unfunded actuarial accrued liability or surplus.
To ensure consistency with the principles and objectives described above, the GFOA recommends that a pension funding policy treat each of its core elements as follows:
Actuarial cost method. The actuarial cost method selected for funding purposes should conform to actuarial standards of practice and allocate normal costs over a period beginning no earlier than the date of employment and should not exceed the last assumed retirement age. Moreover, the selected actuarial cost method should be designed to fully fund the long-term costs of promised benefits, consistent with the objective of keeping contributions relatively stable and equitably allocating the costs over the employees’ period of active service.3 While not the only method that would satisfy this criterion, the entry age method—level percentage of pay normal cost—is especially well suited to achieving this purpose.
Asset smoothing. The method used for asset smoothing should:
- Be unbiased relative to market. For example:
Amortization. Amortization of the unfunded actuarial accrued liability5 should:
- Use fixed (closed) periods that
Additional considerations for plans closed to new entrants. When a plan is closed to new participants, the aggregate actuarial cost method – level percentage of pay normal cost – is especially well suited for funding.
For closed plans with no remaining active members:
- Special attention needs to be given to the mix of investments (given the shorter time horizon); and
- In comparison to open plans:
For closed plans that still have active members:
- The continued use of level percent of member compensation amortization remains appropriate, but not for a long period (i.e., as the number of active members decreases); and
- In comparison to open plans:
Other policy statements. A funding policy can also give a government an opportunity to make statements identifying the conditions under which future benefit enhancements or reductions would be evaluated. For example, a funding policy could state that future benefit enhancements would only be considered if the cost of those enhancements do not cause the plan’s funded ratio to go below 100%, or in the alternative, cause the ADC to rise above a certain level.
1 Some government employers choose to augment other elements of employee compensation rather than providing OPEB.
2 See GASB Statement No. 75, Accounting and Financial Reporting by Employers for Postemployment Benefits Other Than Pensions. The Financial Accounting Standards Board (FASB) has required the same of private-sector employers since the implementation of FASB Statement No. 106, Employers’ Accounting for Postretirement Benefits Other Than Pensions, which was released in 1990.
3 Employers using some other actuarial cost method should carefully monitor demographic changes and trends in the covered workforce inasmuch as such changes could result in increased employer contributions as a percentage of payroll.
4 Generally, the appropriate corridor will depend upon the length of the smoothing period, with longer smoothing periods requiring narrower corridors.
5 Special considerations may apply to the amortization of a surplus (e.g., use of a longer amortization period).
