2 November 2013 Public Employees Retirement Association of Minnesota St. Paul, Minnesota Dear Trustees of the : The results of the July 1, 2013 annual actuarial valuation of the are presented in this report. This report was prepared at the request of the Board and is intended for use by the Board and staff and those designated or approved by the Board. This report may be provided to parties other than the Plan only in its entirety. GRS is not responsible for the consequences of any unauthorized use of this report. The purpose of the valuation is to measure the Plan s funding progress, to determine the required contribution rate for the fiscal year beginning July 1, 2013, and to determine the actuarial information required by Governmental Accounting Standards Board (GASB) Statement No. 25. Note that we have not attempted to quantify the impact of GASB Statements No. 67 and No. 68 in this report. The valuation was based upon information furnished by the Public Employees Retirement Association of Minnesota (PERA), concerning benefits, financial transactions, plan provisions and active members, terminated members, retirees and beneficiaries. We checked for internal and year-to-year consistency, but did not otherwise audit the data. We are not responsible for the accuracy or completeness of the information provided by PERA. Actuarial assumptions, including discount rates, mortality tables and others identified in this report, are prescribed by Minnesota Statutes Section , the Legislative Commission on Pensions and Retirement (LCPR), and the Trustees. These parties are responsible for selecting the plan s funding policy, actuarial valuation methods, asset valuation methods, and assumptions. The policies, methods and assumptions used in this valuation are those that have been so prescribed and are described in the Actuarial Basis of this report. PERA is solely responsible for communicating to GRS any changes required thereto. Future actuarial measurements may differ significantly from the current measurements presented in this report due to such factors as the following: plan experience differing from that anticipated by the economic or demographic assumptions; changes in economic or demographic assumptions; increases or decreases expected as part of the natural operation of the methodology used for these measurements (such as the end of an amortization period or additional cost or contribution requirements based on the plan s funded status); and changes in plan provisions or applicable law. Due to the limited scope of our assignment, we did not perform an analysis of the potential range of such future measurements. This report should not be relied on for any purpose other than the purpose described herein. Determinations of the financial results associated with the benefits described in this report in a manner other than the intended purpose may produce significantly different results.

5 Summary of Valuation Results Contributions The following table summarizes important contribution information as described in the Development of Costs section. Actuarial Valuation as of Contributions July 1, 2013 July 1, 2012 Statutory Contributions - Chapter 353 (% of Payroll) 13.50% 13.50% Required Contributions - Chapter 356 (% of Payroll) 15.15% 14.46% Sufficiency / (Deficiency) (1.65)% (0.96)% The statutory contribution deficiency increased from 0.96% of payroll to 1.65% of payroll. The primary reason for the increase is the recognition of investment losses from prior years in the actuarial value of assets. Lower than expected salaries resulted in a liability gain but also increased the payment on the unfunded actuarial accrued liability as a percent of payroll. Statutory contributions are not sufficient to fully amortize the unfunded actuarial accrued liability over the statutory amortization period of 18 years. Based on the current member and employer contribution rates and other methods and assumptions described in this report, including the actuarial value of assets, it would take 26 years to eliminate the unfunded liability. Current contributions are not sufficient to cover interest on the unfunded liability, which will result in the unfunded liability growing during the short-term. The Plan Assets section provides detail on the plan assets used for the valuation including a development of the actuarial value of assets (AVA). The market value of assets (MVA) earned approximately 14.2% for the plan year ending June 30, The AVA earned approximately 6.2% for the plan year ending June 30, 2013 as compared to the assumed rate of 8.0%. The assumed rate is mandated by Minnesota Statutes. Participant reconciliation and statistics are detailed in the Membership Data section. The Actuarial Basis section includes a summary of plan provisions and actuarial methods and assumptions used for the calculations in this report. The Plan Accounting sections detail the required accounting information for the Plan under GASB No. 25 (as amended by GASB No. 50). Statements No. 67 and No. 68, issued in June 2012, replace the requirements of Statements No. 25 and No. 27, respectively. Statement No. 68, effective for the fiscal year beginning July 1, 2014, sets the accounting rules for the employers that sponsor or contribute to public retirement systems, while Statement No. 67, effective for the fiscal year beginning July 1, 2013, sets the rules for the systems themselves. Accounting information prepared according to Statements No. 67 and No. 68 will be provided in a separate report. 1

6 Summary of Valuation Results A summary of principal valuation results from the current valuation and the prior valuation follows. Any changes in Plan provisions, actuarial assumptions or valuation methods and procedures between the two valuations are described after the summary.

7 Summary of Valuation Results Valuation of Future Post-Retirement Benefit Increases A very important assumption affecting the valuation results is the expectation of future post-retirement benefit increases. The Plan s accrued liability funding ratio (on a market value of assets basis and assuming 1.0% post-retirement benefit increases in all future years) is currently 77.8%. If the Plan reaches a funding ratio of 90% (on a market value of assets basis) for two consecutive years in the future, post-retirement increases will revert to the 2.5% level. The funding ratio threshold that must be attained to pay a 2.5% postretirement benefit increase to benefit recipients was changed in 2013 from 90% for one year to 90% for two consecutive years. The funding ratio threshold that determines when a 2.5% postretirement benefit increase must decrease to 1.0% was changed in 2013 from less than 90% for one year to less than 80% for one year or less than 85% for two consecutive years. We performed a projection of liabilities and assets, using the 2013 valuation results as a baseline and assuming future experience follows the valuation assumptions (including future investment returns of 8.0% for four years and 8.5% thereafter). In addition, the projection utilized the following methods and assumptions: Liabilities and normal cost assume future benefit increases of 2.5% for all years Cash flow (benefit payments paid) assuming future benefit increases at 1.0% per year Level normal cost as a percent of pay (assuming total payroll increases as assumed in the valuation for purposes of amortizing the unfunded liability) Current statutory contributions (i.e. not including potential contribution increases under the contribution stabilizer statutes) Based on these assumptions and methods, the projection indicates that the funded status of this plan is not expected to reach 90% within the next 15 years of the projection. The liabilities in this report are based on the assumption that the post-retirement benefit increase will remain at the reduced level of 1.0% indefinitely. We relied on direction from PERA on this issue. If we assumed future post-retirement benefit increases of 2.5% instead of 1.0%, the actuarial accrued liability would be $21.9 billion instead of $19.4 billion, resulting in a funded ratio of 68.8% (on a market value basis) as of July 1,

8 Supplemental Information The remainder of the report includes information supporting the results presented in the previous sections. Plan assets presents information about the plan s assets as reported by the Minnesota State Retirement System. The assets represent the portion of total fund liabilities that has been funded. Membership data presents and describes the membership data used in the valuation. Development of costs shows the liabilities for Plan benefits and the derivation of the contribution amount. Actuarial basis describes the Plan provisions, as well as the methods and assumptions used to value the plan. The valuation is based on the premise that the Plan is ongoing. Plan accounting under GASB No. 25 (as amended by GASB No. 50) shows the disclosures required by GASB Statement No. 25 as amended by GASB Statement No. 50. Glossary defines the terms used in this report. 4

25 Development of Costs Actuarial Valuation Balance Sheet (Dollars in Thousands) The actuarial balance sheet is based on the principle that the long-term projected benefit obligations of the plan should be ideally equal to the long-term resources available to fund those obligations. The resources available to meet projected obligations for current members consist of current fund assets plus the present value of anticipated future contributions intended to fund benefits for current members. In the exhibit below, B.2 is the estimated present value of contributions to fund the normal cost rate for current members until their respective termination dates. Item B.1 is the present value of the total 13.50% statutory contribution net of normal cost and anticipated plan expenses during the period from the valuation date to the statutory unfunded amortization date. The contributions made in excess of amounts required for current benefit payments are accumulated as a reserve to help meet benefit payments in later years. It is this reserve system which permits the establishment of a level rate of contribution each year. June 30, 2013 A. Actuarial Value of Assets $ 14,113,295 B. Expected Future Assets 1.

31 Actuarial Basis Actuarial Methods All actuarial methods are prescribed by Minnesota Statutes, the Legislative Commission on Pensions and Retirement, or the Board of Trustees. Different methodologies may also be reasonable and results based on other methodologies would be different. Actuarial Cost Method Actuarial Accrued Liability and required contributions in this report are computed using the Entry Age Normal Cost Method. This method is prescribed by Minnesota Statute. Under this method, a normal cost is developed by amortizing the actuarial value of benefits expected to be received by each active participant (as a level percentage of pay) over the total working lifetime of that participant, from hire to termination. Age as of the valuation date was calculated based on the dates of birth provided by the Fund. Entry age for valuation purposes was calculated as the age on the valuation date minus the provided years of service on the valuation date. To the extent that current assets and future normal costs do not support participants expected future benefits, an unfunded actuarial accrued liability ( UAAL ) develops. The UAAL is amortized over the statutory amortization period using level percent of payroll assuming payroll increases. The total contribution developed under this method is the sum of normal cost, expenses, and the payment toward the UAAL. Select and Ultimate Discount Rate Methodology Based on direction from the LCPR s actuary, the select and ultimate discount rate methodology was applied to the entry age normal results as follows: 1. The present value of projected benefits was calculated using the prescribed select and ultimate discount rates. 2. An equivalent single interest rate that produced approximately the same present value of projected benefits was determined. 3. The equivalent single interest rate was used to determine the entry age normal accrued liability and normal cost. The equivalent single interest rate used in this valuation was 8.37% (8.34% last year). Funding Objective The fundamental financing objective of the fund is to establish contribution rates which, when expressed as a percentage of active member payroll, will remain approximately level from generation to generation and meet the required deadline for full funding. Decrement Timing All decrements are assumed to occur mid-year. 27

32 Actuarial Basis Actuarial Methods (Concluded) Asset Valuation Method The assets are valued based on a five-year moving average of expected and market values (five-year average actuarial value) determined as follows: At the end of each plan year, an average asset value is calculated as the average of the market asset value at the beginning and end of the fiscal year net of investment income for the fiscal year; The investment gain or (loss) is taken as the excess of actual investment income over the expected investment income based on the average asset value as calculated above; The investment gain or (loss) so determined is recognized over five years at 20% per year; The asset value is the sum of the market asset value plus the scheduled recognition of investment gains or (losses) during the current and the preceding four fiscal years. The Minnesota Post Retirement Investment Fund (Post Fund) was dissolved on June 30, For the purpose of determining the actuarial value of assets, the Post Fund asset loss for the fiscal year ending June 30, 2009 was recognized incrementally over five years at 20% per year, similar to the smoothing described above. Prior to June 30, 2009, Post Fund asset gains and losses were not smoothed. Payment on the Unfunded Actuarial Accrued Liability Payment equals a level percentage of payroll each year to the statutory amortization date of June 30, 2031 assuming payroll increases of 3.75% per annum. If there is a negative Unfunded Actuarial Accrued Liability, the surplus amount is amortized over 30 years as a level percentage of payroll. Projected payroll is multiplied by in the determination of the present value of future payroll to account for timing differences (as required by the Standards for Actuarial Work). Changes in Methods since Prior Valuation None. 28

33 Actuarial Basis Summary of Actuarial Assumptions The following assumptions were used in valuing the liabilities and benefits under the plan. All actuarial assumptions are prescribed by Minnesota Statutes, the Legislative Commission on Pensions and Retirement (LCPR), or the Board of Trustees. These parties are responsible for selecting the assumptions used for this valuation. The assumptions prescribed are based on the last experience study, dated August 2009, prepared by a former actuary. The Allowance for Combined Service Annuity was also based on a recommendation by a former actuary. We are unable to judge the reasonableness of this assumption without performing a substantial amount of additional work beyond the scope of the assignment. Investment return Benefit increases after retirement Salary increases Payroll growth Mortality rates Healthy Pre-retirement Healthy Post-retirement Select and Ultimate Rates: July 1, 2013 to June 30, % per annum post-retirement 8.00% per annum pre-retirement July 1, 2017 and later 7.50% per annum post-retirement 8.50% per annum pre-retirement Payment of 1.00% annual benefit increases after retirement are accounted for by using the 7.50% post-retirement assumption (7.0% during 4-year select period), as required by Minnesota Statute. Mathematically, this assumption funds a postretirement benefit increase of 0.9% instead of 1.0%. This valuation does not reflect any potential additional benefit increases payable if the plan s funding ratio exceeds 90%. Reported salary at valuation date increased according to the rate table, to current fiscal year and annually for each future year.
