This valuation report is only an estimate of the Plan’s financial condition as of a single date.It can neither
predict the Plan’s future condition nor guarantee future financial soundness.Actuarial valuations do not
affect the ultimate cost of Plan benefits,only the timing of Plan contributions.While the valuation is based on
an array of individually reasonable assumptions,other assumption sets may also be reasonable and
valuation results based on those assumptions would be different.No one set of assumptions is uniquely
correct. Determining results using alternative assumptions is outside the scope of our engagement.
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 future measurements.The District has the final decision
regarding the appropriateness of the assumptions and adopted them as indicated in this report.
Actuarial computations presented in this report are for purposes of determining the recommended funding
amounts for the District.The calculations in the enclosed report have been made on a basis consistent with
our understanding of the District’s funding requirements and goals as well as our understanding of the plan
provisions described on pages 18-22 of this report.Determinations for purposes other than meeting these
requirements may be significantly different from the results contained in this report.Accordingly,additional
determinations may be needed for other purposes.
As requested,we have performed an actuarial valuation of the Metropolitan St.Louis Sewer District
Employees'Pension Plan as of December 31,2020 for determining contributions for the calendar year
ending December 31,2021.Our findings are set forth in this actuary’s report.This report reflects the benefit
provisions in effect on December 31, 2020.
In preparing this report,we relied,without audit,on information (some oral and some in writing)supplied by
the District and U.S.Bank.This information includes,but is not limited to,statutory provisions,employee
data,and financial information.We found this information to be reasonably consistent and comparable with
information used for other purposes.The valuation results depend on the integrity of this information.If any
of this information is inaccurate or incomplete,our results may be different,and our calculations may need to
be revised.
Actuarial assumptions,including discount rates,mortality tables,and others identified in this report,and
actuarial cost methods are prescribed by the District.The District is 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.
The valuation results have been developed using models employing standard actuarial techniques.We have
reviewed the models,including their inputs,calculations,and outputs for consistency,reasonableness,and
appropriateness to the intended purpose and in compliance with generally accepted actuarial practice and
relevant actuarial standards of practice.The models,including all input,calculations,and output may not be
appropriate for any other purpose.

The results of this valuation are used to actuarially determine contribution amounts to the Plan for the 2021
calendar year.A comparison of actuarially determined contribution amounts for the current and immediately
preceding valuation are shown below:
The market value of plan assets increased from $296,202,647 at December 31,2019 to $326,912,684 at
December 31,2020.A balance sheet and statement of income and disbursements are presented on pages
7 and 8, respectively. The net market rate of return was 12.5% for the period.
The actuarial value of assets increased from $290,911,258 at December 31,2019 to $307,150,063 at
December 31,2020.The development of the December 31,2020 actuarial value of assets is presented on
page 9. The net actuarial rate of return for the period was 7.7% vs. the assumed rate of 6.75%.
Due to the asset smoothing method used,there are $19,762,621 of net investment gains that have not yet
been recognized in the Actuarial Value of Assets.
All actuarial assumptions,methods and plan provisions remained the same as the prior year.Descriptions of
these can be found on pages 14-22.
The funding method is the Entry Age Normal method where Normal Costs are computed as a level percent
of pay.The Unfunded Accrued Liability is amortized in layers over a period of 20 years.The annual
amortization payment is calculated as a level dollar amount.The amortization period was reset to 20 years
for all outstanding bases effective December 31, 2008.
There was a decrease in the actuarially determined contribution as compared to the preceding year.The
primary reasons for the decrease were asset return on an actuarial value basis of 7.7%vs.the assumed
6.75%, salary increases lower than expected and mortality gains.

The key elements of the actuarial funding process are illustrated in the Actuarial Balance Sheet.The format
of the balance sheet captures the essential purpose of an actuarial cost method -the determination of assets
sufficient to provide for pension benefits.
The Actuarial Present Value of Current and Prospective Plan Benefits is the liability that must be balanced by
Current and Prospective assets.The Present Value of Future Normal Cost Contributions represents the
prospective assets from contributions that will be made for costs allocated to the future.

The Entry Age Normal Cost Method on a closed group basis was used.Normal costs are computed as a
level percent of pay.Changes in the Entry Age Normal Unfunded Accrued Liability (UAL)are amortized on a
level dollar basis over layered 20 year periods.For the December 31,2008 valuation,the amortization period
for outstanding bases was reset to 20 years.
The Actuarial Value of Assets is equal to the average of the Adjusted Market Values for the current and two
previous valuation dates.The Adjusted Market Value for the current valuation date is equal to the Market
Value of Assets.The Adjusted Market Values for the two previous valuation dates are equal to the Market
Values as of the respective valuation dates increased for contributions and expected return on Actuarial
Assets and decreased for benefit payments and expenses.

recommends that third parties be aided by their own actuary or other qualified professional when reviewing the Milliman work product.
The purpose of this appendix is to identify,assess,and provide illustrations of risks that are significant to the
Plan, and in some cases to the Plan’s participants.
The results of the actuarial valuation are based on one set of reasonable assumptions.However,it is almost
certain that future experience will not exactly match the assumptions.As an example,investments may
perform better or worse than assumed in any single year and over any longer time horizon.It is therefore
important to consider the potential impacts of these potential differences when making decisions that may
affect the future financial health of the Plan, or of the Plan’s participants.
Actuarial Standard of Practice No.51 (ASOP 51)addresses these issues by providing actuaries with
guidance for assessing and disclosing the risk associated with measuring pension liabilities and the
determination of pension plan contributions. Specifically, it directs the actuary to:
Disclose plan maturity measures and historical information that are significant to understanding the
plan’s risks.
In addition,as plans mature they accumulate larger pools of assets and liabilities.This increases the
potential risk to plan funding and the finances of those who are responsible for plan funding.As an example,
it is more difficult for a plan sponsor to deal with the effects of a 10%investment loss on a plan with $1 Billion
in assets and liabilities than if the same plan sponsor is responsible for a 10%investment loss on a plan with
$1 Million in assets and liabilities.Since pension plans make long-term promises and rely on long-term
funding,it is important to consider how mature the plan is today,and how mature it may become in the
future.
ASOP 51 states that if in the actuary’s professional judgment,a more detailed assessment would be
significantly beneficial in helping the individuals responsible for the plan to understand the risks identified by
the actuary, then the actuary should recommend that such an assessment be performed.
This appendix uses the framework of ASOP 51 to communicate important information about:significant risks
to the Plan, the Plan’s maturity, and relevant historical Plan data.
Definition:This is the potential for total plan liabilities to become more heavily weighted toward inactive
liabilities over time.
Identification:The Plan is subject to maturity risk because as Plan assets and liabilities continue to
grow, the impact of any gains or losses on the assets or liabilities also becomes larger.
Assessment:Currently assets are equal to 24 times last year’s contributions indicating a one-year
asset loss of 10% would be equal to 2.4 times last year’s contributions.

purposes.Milliman does not intend to benefit and assumes no duty or liability to other parties who receive this work.Milliman
recommends that third parties be aided by their own actuary or other qualified professional when reviewing the Milliman work product.
Assessment:If the interest rate changes by 1%,the estimated percentage change in pension liability
is approximately 11%.
Identification:The pension liabilities reported herein have been calculated by assuming that
participants will follow patterns of demographic experience (e.g.mortality,withdrawal,disability,
retirement,form of payment election,etc.)as described in the appendix.If actual demographic
experience or future demographic assumptions are different from what is assumed to occur in this
valuation,future pension liabilities,funding contributions and funded status may differ significantly from
those presented in this valuation.
Definition:This is the potential for participants to retire and receive subsidized benefits more valuable
than expected.
Identification:This plan has valuable early retirement benefits.If participants retire at earlier ages than
anticipated by the actuarial assumptions, it is expected that additional funding will be required.
Identification:To the extent that actual investment returns differ from the assumed investment return,
the plan’s future assets,funding contributions and funded status may differ significantly from those
presented in this valuation.
Identification:The pension liabilities reported herein have been calculated by computing the present
value of expected future benefit payments using the interest rate(s)described in the appendix.If
interest rate(s)in future valuations are different from those used in this valuation,future pension
liabilities,funding contributions and funded status may differ significantly from those presented in this
valuation.As a general rule,using a higher interest rate to compute the present value of future benefit
payments will result in a lower pension liability,and vice versa.One aspect that can be used to
estimate the impact of different interest rates is the plan’s duration.
