Re: Cost of Living Adjustment (COLA) Study – Options 1, 2, and 3 Dear Donna: Cavanaugh Macdonald was asked to perform several cost studies related to the addition of a COLA provision to the IPERS benefit structure. We initially prepared a study of Option 1 and discussed those results with you before proceeding with Options 2 and 3. For completeness, the results for all three COLA options are included in this report. The COLA designs under discussion are described below. They apply to all three IPERS membership groups, begin funding the COLA effective July 1, 2017 and have an implementation date of July 1, 2026. Furthermore, the proposed COLA excludes the pre-1990 retirees who already have a COLA-type provision.

Option 1 is an annual COLA equal to the lesser of CPI and 2.00%, commencing at the later of age 66 or one year after retirement. The purpose of the cost study was to determine the increase in the contribution rate required to fund the proposed COLA.

Option 2 reduces the 2% COLA in Option 1 to a level where the increase in the contribution rate for each group is approximately 1%. The purpose of the cost study was to determine the level of COLA that could be provided for an increase in the contribution rate of 1%.

Option 3 provides an annual simple (rather than compound) COLA equal to the lesser of CPI and 2.00%, commencing at the later of age 75 or one year after retirement. The COLA base for the simple COLA is the lesser of the member’s benefit at retirement or $22,000 for members retired prior to July 1, 2017. The COLA base of $22,000 is adjusted annually by the growth in the median or average new retiree pension amount. Further, the COLA is reduced pro rata for years of service less than 30. The purpose of the cost study was to determine the increase in the contribution rate required to fund the proposed COLA.

Ms. Donna Mueller August 2, 2016 Page 2 Analysis

We modeled the proposed COLA provisions using the same actuarial methods and assumptions that were used in our June 30, 2015 valuation report and the projection model created with the valuation results. We assumed that the CPI would exceed 2.00% in all future years so effectively a 2.00% COLA (or less for Option 2) was valued for all years commencing on or after July 1, 2026. For Option 3, we assumed that the $22,000 maximum COLA base would increase at 4% per year, the same as the current wage growth assumption. As you requested, the projections reflect the estimated investment return for FY 2016 of -0.50%, as provided by the IPERS investment staff. The attachments to this letter contain a number of exhibits. For each of the three COLA Options that were studied, there are nine exhibits:

Exhibit 1: Projection of Funded Ratio (Regular Members) Exhibit 2: Projection of Actuarial and Required Contribution Rate (Regular Members) Exhibit 3: Projection of Funded Ratio (Sheriffs & Deputies) Exhibit 4: Projection of Actuarial and Required Contribution Rate (Sheriffs & Deputies) Exhibit 5: Projection of Funded Ratio (Protection Occupation) Exhibit 6: Projection of Actuarial and Required Contribution Rate (Protection Occupation) Exhibit 7: Summary of Graph Data (Regular Members) Exhibit 8: Summary of Graph Data (Sheriffs & Deputies) Exhibit 9: Summary of Graph Data (Protection Occupation)

For comparison purposes, the graphs also show the baseline, obtained using the current benefit provisions with the same actuarial assumptions including the FY 2016 estimated investment return.

Results

As expected, the addition of a COLA to the benefit structure increases the actuarial contribution rate. However, the amount of the increase is not constant over time. Ultimately, the cost difference is the increase in the normal cost rate. While this is the long-term cost difference, the COLA described would immediately increase the Unfunded Actuarial Liability (UAL) and result in an additional contribution rate until this additional liability was paid off. The following tables summarize the difference in the ultimate normal cost rate (in 2045), the immediate change in UAAL, and the average additional contribution rate over the next 30 years. These tables show the cost of Options 1 and 3, and indicate that Option 2 can provide a 0.60% COLA for Regular members and Protection Occupation members and a 0.50% COLA for Sheriffs & Deputies members.

Ms. Donna Mueller August 2, 2016 Page 4 In our calculations, we assumed that the increase in the UAL from the COLA would be funded over a closed 30-year period. The IPERS Funding Policy, adopted by the Investment Board, does not specify the amortization period for a benefit change, so the Board could select a different amortization period. Because the COLA implementation would be delayed for 10 years (although funding would start right away), a 30-year amortization period would essentially provide for a 20-year amortization period at the time the COLA payments begin. This approach also leads to a smoother contribution rate pattern which allows for a more direct comparison of the impact of the COLA provision on the contribution rate. As may be noted, Options 1 and 2 do not have costs that are exactly proportional to the amount of the COLAs provided. This is largely a result of the stability features of the funding policy used to determine IPERS’ contribution rates. Due to the COLA design features of Option 3, comparing results across the three membership groups as well as over time may lead to observations that are not intuitive. For example, based on the actuarial assumptions, members in the Sheriffs and Deputies group and the Protection Occupation group are anticipated to retire with less than 30 years of service. Therefore, for these members the COLA under Option 3 is reduced. In addition, the deferral of the COLA to age 75 has a greater impact on these groups because the deferral period tends to be longer. Lastly, the members in these groups tend to have higher salaries and thus are likely to be above the $22,000 (indexed) COLA base, ultimately resulting in a lower COLA. Data, Assumptions and Methodology

The data, actuarial assumptions, and actuarial methods used in these projections are the same as those utilized in the June 30, 2015 valuation. For projection purposes, we developed a hypothetical new entrant profile based on the demographics of recent hires for each membership group. The active membership was assumed to remain level throughout the projection period so new entrants were assumed to replace those members leaving active employment. For purposes of evaluating the COLA provisions, it was assumed that CPI would exceed 2.00% in all years so a 2.00% annual COLA was valued under Option 1 and 3. In addition, for Option 3, the COLA base was assumed to escalate at 4% per year, consistent with the current wage growth assumption. Because this work was prepared at the end of FY 2016, the estimated market return of -0.50% for FY 2016, as provided by the IPERS investment department, was reflected in the projections. For all other years, the investment return was assumed to be the actuarial rate of 7.50%, and all other assumptions were assumed to be met exactly. To the extent that actual experience does not exactly match assumed experience, future results will differ from the results shown. Quantification of the range of such results is beyond the scope of this project. We wish to emphasize that a change in retirement patterns influenced by such factors as the implementation of a COLA, changes in Social Security, or changes in the delivery of medical care to retirees could all impact the actual results. The funded ratios shown in the graphs were calculated as the ratio of the actuarial value of assets to the actuarial liability. As is the case with the valuation report, these numbers are indicative of the System’s funding progress over the long-term. The estimated contribution rates were
