The 2022 Global Survey of Accounting Assumptions for Defined Benefit Plans is the 33rd annual WTW survey of assumptions selected by major corporations for their defined benefit (DB) plans around the world.
In broad terms, accounting standards aim to enable employers to approximate the cost of an employee’s pension or other postretirement benefit over that employee’s service tenure. Any benefit accounting method that recognizes the cost of benefits before their payment becomes due must be based on estimates or assumptions about future events that will determine the amount and timing of benefit payments.
Two key economic assumptions in the determination of benefit costs under an accounting standard are the discount rate and inflation. Under ASC 715, there is another key economic assumption: the expected long-term rate of return on plan assets (for funded plans). In many countries, four additional economic assumptions, which are somewhat linked to inflation, can play a key role: (1) rate of salary increase; (2) rate of increase in pensions, both in deferment and in payment; (3) cash balance interest crediting rate; and (4) rate of increase in the social security parameters reflected in the pension benefit formula. We discuss these in our full report.
Although this survey mainly explores economic assumptions, we have again shown data regarding mortality assumptions, which are receiving closer attention because of increasing longevity.
The observations in this report reflect data at or near the end of 2021. Consideration should be given to market movements since December 31, 2021. As discussions around accounting assumptions start for the 2022 year-end, your WTW consultant would welcome the opportunity to discuss how that volatility might have affected your plans' liabilities and assets.
Our full report, which represents 1,420 companies with data from 49 countries, includes the following key findings:
Discount rates are used to calculate benefit obligations as well as the service and interest cost portion of the employee benefit cost.
While ASC 715 does not explicitly define the quality of the bond yields, most plan sponsors base their discount rates on AA-rated bonds. IAS 19 refers to high-quality corporate bond yields, which is generally interpreted to mean AA-rated or better. The primary focus for corporations has been placed on long-term, high-quality corporate bonds of appropriate duration consistent with the benefit obligation.
Where there is no deep market in corporate bonds, it is customary for ASC 715 discount rates to be based on government bonds but adjusted by some level of risk premium to approximate corporate bond yields. By contrast, IAS 19 requires the use of government bonds with no additional risk premium in such situations; therefore, we present discount rates for both accounting standards separately.
Figure 1 shows the average discount rates for benefit obligations at the end of 2021 and 2020, using ASC 715 and IAS 19. This table include values for companies with December 31 balance sheet dates only.
The similarity of ASC 715 and IAS 19 discount rates in most of the countries shown in Figure 1 reflects the fact that these countries are regarded as having a sufficiently deep corporate bond market. In our complete findings, we see that in some countries where the corporate bond market is not deep enough — Argentina, Ecuador, Mexico, Thailand and the United Arab Emirates, for instance — the average discount rate is noticeably lower under IAS 19 than under ASC 715.
For countries with a deep market in corporate bonds, it has become increasingly common to match expected cash flows from the plan either to a portfolio of bonds that generates sufficient cash flows or to a notional yield curve generated from available bond information. This is a common approach in Canada, the Eurozone, Japan, the U.K. and the U.S. and is becoming more common in Australia, Norway, Sweden and Switzerland.

The expected rate of return on assets is the long-term expectation of the annual earnings rate on the assets of the pension fund. Under ASC 715, the expected rate of return on assets is a component of the employee benefit cost. Expected rates of return reflect the plan sponsor’s outlook while considering the plan’s asset allocation.
Figure 3 shows the average allocation split among equities, bonds, property, cash and insurance contracts/other investments. The weighted average of the expected long-term rate of return on each class gives an indication of the appropriate expected return on assets assumption. In comparison with results from last year’s survey, we witnessed only minor changes in asset allocations across the board.
Asset allocations are likely to be driven by several factors, such as funded status, sponsor risk appetite, nature and maturity of the obligations, and local regulations. The complete results show that sponsors in Australia, Hong Kong, New Zealand and Puerto Rico are holding relatively large equity positions (more than 40%). Brazil, India, Indonesia, Mexico and Taiwan are countries where regulatory investment restrictions influence their asset mix.
Canada: 34% equities, 58% bonds; Germany: 14% equities, 20% bonds, 63% insurance or other; Japan: 28% equities, 42% bonds, 28% insurance or other; Netherlands: 13% bonds, 77% insurance or other; Switzerland: 22% equities, 22% bonds, 13% property, 39% insurance or other; United Kingdom: 18% equities, 44% bonds, 32% insurance or other; United States: 38% equities, 44% bonds, 12% insurance or other
Figure 4 shows the average expected rates of return for 2022 and 2021 expense for all plans reported under ASC 715 only. The year-on-year changes of expected rates of return assumptions vary even within developed countries both in direction and magnitude of change. High levels of uncertainty regarding both the fixed-income and equity markets, paired with higher inflation expectations, may be the drivers behind these results. As expected, there is a positive correlation between expected rate of return and the amount of plan assets held in equities by plan sponsors.

Figure 5 shows the assumed life expectancy at age 60 for both a male currently age 60 and a male currently age 40. Note that some tables are generational, while others are static. The latter do not include an allowance for improvement in life expectancy for future employee cohorts; thus, life expectancy at age 60 is the same for a male currently age 60 and a male currently age 40.
The majority of surveyed countries have implied life expectancies of between 20 and 30 years. The impact of the differences in this assumption will vary depending on the payment election assumption between lump sum and annuity, the form of the annuity and the mix of current plan participants, among other factors.
Life expectancy at age 60 of a male currently age 40: Switzerland 28.33, Netherlands 28.79, United Kingdom 28.50, Germany 28.03, Canada 27.43, United States 26.94, Japan 24.51. Life expectancy at age 60 of a male currently age 60: Switzerland 26.52, Netherlands 26.78, United Kingdom 26.75, Germany 25.07, Canada 26.34, United States 25.26, Japan 24.51
The projected benefit security ratio is the ratio of the current market value of plan assets to the plan’s projected benefit obligation. The projected benefit obligation is the actuarial present value of all benefits attributed by the benefit formula to service before the balance sheet date, including benefits based on expected future salary increases. Under IAS 19, this is known as the defined benefit obligation.
Figure 6 shows the average projected benefit security ratio for 2022 and 2021, for funded plans in each country. As can be seen in the table, ratios improved for all major economies, aided by discount rate increases and a robust equity market performance. This is also seen in the full report, where most countries increased their average ratio, including several countries in which the average ratio improved by more than 10 basis points.

The 2022 Global Survey of Accounting Assumptions for Defined Benefit Plans is the 33rd annual WTW survey of assumptions selected by major corporations for their DB plans around the world.
The full report covers accounting assumptions under various global standards; for this report, 53% of the survey participants report under ASC 715 and 47% report under IAS 19 or other similar accounting standards. This is similar to the mix of participants last year.
We collected retirement plan data using a survey form and various WTW databases that maintain accounting assumptions. Results in the full report are shown on a plan-level basis; therefore, some results could differ from what is reported on a company level.
WTW believes these surveys have elicited useful information, and we would be pleased to provide you with more detail. A snapshot of findings for a few key markets is available in this executive summary. For further information, or to access the complete survey findings, please contact your WTW consultant or the surey authors.
The 1,420 companies included in the full report have disclosed assumptions for their DB plans. The report reflects data at or near the end of 2021. While this executive summary covers only Canada, Germany, Japan, the Netherlands, Switzerland, the United Kingdom and the United States, the following 49 countries are represented in the full report:
*Hong Kong is a special administrative region of China.
**Puerto Rico is an unincorporated territory of the United States.
