This is the twelfth periodic survey (click here to see survey results in a new window) which ranks the funding assumptions used by California’s public pension systems from “most conservative” to “most optimistic.” In the related spreadsheet, the “most conservative” system is ranked as #1 and “most optimistic” system is ranked as #36.
There is no absolute “right” or “wrong” in setting assumptions. There can be a number of valid reasons that an assumption package for Entity A differs from Entity B. Entity A might have a larger equity allocation than Entity B. Entity C might wish to have more conservative assumptions to be able to fund potential ad hoc benefits. The nation’s largest state plan, CalPERS, may be able to have certain size-related investment efficiencies unavailable to smaller sponsors.
A seeming contradiction has existed during the decade in which these surveys have been completed. There has not been even one instance of ANY entity increasing their assumed rate of investment return during the past 12 years! — despite a decade-long bull market. This raises two questions: Were assumed investment returns too high a decade ago? Are current assumed returns fully reflective of the timing and duration of the next bear market? We offer some observations at the end of this analysis.
Nor does traditional actuarial funding address a paradox: other factors equal, more contribution volatility exists for better funded plans than those with lower funded ratios. Actual investment returns can diverge wildly from assumed returns during a market cycle. Higher asset levels mean that the dollar magnitude of potential actuarial gains or losses is also greater. After the “learning experience” brought about by the 2001-2009 bear market, some Systems established policies which would keep a greater reserve during the “good times” when and if funded ratios again exceed 100%. Other entities, such as CalPERS, have decided that traditional smoothing methods did not achieve desired stability and have used a blunt approach which directly smoothes contribution changes over a period of years — on top of other smoothing methods. Segments of the actuarial community believe that current professional standards, if in place during the 1990’s, might have precluded today’s environment. Perhaps so. Such changes will certainly help but the “political risk” of benefit decisions during the “good” times will remain.
To the extent actuarial losses occur in the future, such losses may become more problematic due to the changing demographics of maturing systems. For many systems, the number of inactive members has approached or exceeded the number of active membership in recent years. Spreading losses on a relatively smaller payroll base means more volatility in contribution rates, other factors equal.
Even though active employees benefit in their retirement years by having well funded systems, making assumptions more conservative can have a “cost” for actives. Lower assumed investment assumptions often directly or indirectly translate into higher employee contributions.
Defining some of the characteristics of “most conservative” versus “most optimistic” is useful.
|Most Conservative||Most Optimistic|
Lower Assumed Investment Return
Higher Assumed Investment Return
|Higher Assumed Pay Increases||Lower Assumed Pay Increases|
|Shorter Amortization periods||Longer Amortization Periods|
Explicit Expense Load
No Explicit Expense Load
|Entry Age Normal Funding||Projected Unit Credit Funding|
|Level Dollar Amortization||Level Percent of Pay Amortization|
Using comparative funded ratios, to determine how well funded a plan is, can be misleading:
The most significant development in the 2021 survey, for the ninth straight year, continues to be the lowering of both assumed investment returns and inflation assumptions. Number of entities lowering assumed investment return:
In this year’s survey, only the San Francisco system used an assumed return higher than 7.00%.
Assumed Investment Return
|Base Wage Inflation||3.12%||3.19%||3.23%||3.27%||3.38%|
|“Excess” Assumed Return||3.82%||3.77%||3.79%||3.83%||3.86%|
Several points should be noted on the amortization of unfunded liabilities. “Open” or “rolling” methods will use the same number of years in a future valuation as is been used in the current valuation. “Layered” means that there is a new amortization base established each year which is funded on a “closed” or “declining” basis. If one believes that a best practice is for an individual’s benefit to be fully funded at their anticipated retirement date, sound practice is to have the amortization period be closely correlated with the average future working lifetime of the active member group (typically between 10 and 15 years). 30-year amortization passes a significant part of the cost, attributed to current participants, to a future generation of taxpayers. Over the past decade, most Systems have done a good job of reducing their amortization periods.
All amortization approaches noted in this survey should be assumed to be level percent of payroll unless otherwise indicated. Level-percent-of-payroll amortization will produce a lower current year contribution than level dollar amortization over the same period.SOME OBSERVATIONS ON THE ACTUARIAL PROCESS
If there was ever a scenario where actuarial rates should have gone down, the 2014-2019 period would have seemed ideal for such a scenario. Most entities in our survey were gradually impacted by lower benefit formulas mandated by PEPRA (for post-January 1, 2013 hires). The equity market was continuing its decade-long gallop toward Dow 30,000. Despite those considerable tailwinds, one would have to look long and hard for entities with lower rates in their 2020 valuations when compared to their first post-PEPRA valuation. Strange! Twenty years ago, if you were told that many entities would have employer contribution rates at 30+ % of payroll (with some at or exceeding 50%!!!) and upward, you would be in some state of disbelief.
For the first time, we are showing trailing market returns when they were readily ascertainable from the actuarial valuation report. An observation from our recent reviews is that many entities reported trailing 5-year and 10-year yields that I would deem disappointing. Did active management of equity portfolios often prove to fall short? In general, one might conclude so. In January, CNBC’s equity analyst, Carter Worth, said that “90% of mutual funds have underperformed equity indices over the past 15 years.”
Trailing 5-year returns averaged 5.96%. Trailing 10-year returns averaged a healthier 7.93%. In the few cases where trailing 20-year returns were disclosed, the divergence between actual returns and assumed returns were significant.
Did the actuaries perform their due diligence in the assumed investment returns that were employed? On average, the assumed investment returns have gone down by 1% per annum since our initial 2009 survey. Perhaps decreases needed to be greater. I candidly admit that I was likely wrong during my actuarial career in being too optimistic in setting assumptions. However, even if I was NOT so optimistic, would the Retirement Board have allowed me to use a return lower than the herd? Increasing contribution rates always seem to have marked impact on perpetually tight budgets. If an actuary was convinced that 5.5% was the best long-term assumption, would that actuary be retained by a Retirement Board? Certainly, one could easily find another actuary willing to sign off on a much higher assumed investment return, especially when told by their investment advisors that THEIR active management will earn the System premium returns. All of which argues that a greater degree of independence in the selection of a System’s actuary is a solid idea.
Actuaries have used many approaches to “moderate” any changes in contribution rates. Consider the Great Recession. A number of surveyed entities diverged from their usual policy and gave special dispensation to the plan sponsor. Is there any element of actuarial theory to support such divergence? No! When the equity market was in an unprecedented bull market from 1983-2000, was there recognition of such a “special” unprecedented market? No! Instead, the massive equity gains became the impetus for increasing benefits to unprecedented levels. Sure, after the horses had bolted the barn, some entities decided to implement a buffer during great markets. But the simple reality is that benefit levels are quite likely to never return to their former levels.
One of the contentious elements during the pandemic has been the degree of financial support that Washington DC would offer state and municipal governments. Some of the “pushback” against such aid is that a universal life raft was inequitable when some entities have voluntarily brought on a degree of their financial vulnerability.
Some may dismiss the impact of steadily rising contribution rates. However, consequences exist. In 2017, Joe Nation (in his role with the Stanford Institute of Economic Policy Research. Nation had been a former Democrat Assemblyman) pointed out that the relentless increases in contribution rates have impaired the ability to adequately fund schools and social services.
A clear mission of the actuarial process is to “level out” plan costs from generation to generation. This has clearly not happened during the past 20 years, despite lower benefits and higher employee contributions for many post-2012 hires due to PEPRA. Likely, some good lessons to be learned.
Meanwhile, the impact of PEPRA will grow with each passing year. To see rates eventually go down will be met with relief in many quarters.The source for survey data has largely been from the most recent actuarial valuation report on system web sites. Selected plan administrators and actuaries were sent a draft report to give them the opportunity to make any corrections and updates. The final version will be on the Ramble at roederfinancial.com.
