Exhibit MSD 78A
THIRD DISCOVERY REQUEST OF MIEC
REQUEST NO. 18: Please refer to Exhibit MSD 56B, Appendix 7.2.2 Detailed WW
CIRP Project List. In addition to the Financial Year, please update the exhibit to include the
dates for the Bid Year and Achievement of Full Operation as required by the Consent Decree or
any of its amendments.
RESPONSE: Please see Exhibit MSD 78B - Copy of Appendix 7.2.2 Detailed WW CIRP
Project List Amended May 21, 2019. Please note that the actual data items are Commence
Construction and Placement in Service, to correspond with terms utilized in the SSO Master
Plan for construction related activities.
REQUEST NO. 19: Please refer to Exhibit MSD 56C, Appendix 7.2.3 Detailed WW
CIRP Project List - Not Regulatory or CD. In addition to the Financial Year, please update the
exhibit to include the date MSD is required to complete each of the non -Consent Decree or
regulatory related projects based on State, Federal and local regulatory obligations.
RESPONSE: Please see Exhibit MSD 78C - Copy of Appendix 7.2.3 Detailed WW CIRP
Project List — Not Regulatory or CD Amended May 21, 2019. The projects listed are very
critical. They will allow for the repair, replacement, and rehabilitation of deteriorated closure
gates and gate structures at several 50 plus year old facilities. The District along with the City
of St. Louis is required by the U.S. Army Corp of Engineers to maintain these facilities and the
floodwall. This Mississippi River Floodwall system provides flood protection for the City of St.
Louis and its downtown area. The economic damages to businesses, homes, and institutional
properties that would occur if floodwall protection fails would be substantial. These projects
represent less than 1% of the overall capital program.
REQUEST NO. 20: Please refer to Exhibit MSD 56D - Appendix 7.2.4 Detailed WW
CIRP Project List - Regulatory but not CD. In addition to the Financial Year, please update the
exhibit to include the date MSD is required to complete each regulatory project and all other
timing related milestones required by federal, state or local regulatory requirements.
RESPONSE: Please see Exhibit MSD 78D - Copy of Appendix 7.2.4 Detailed WW CIRP
Project List —Regulatory but not CD Amended May 21, 2019. MSD is obligated to operate and
maintain its facilities to stay in compliance with its regulatory obligations and wastewater
treatment plant permits. NPDES permit violations and negative environmental impacts could
result from the District's failure to complete the treatment plant rehabilitation, repair and
replacement projects. The District utilizes an Asset Management approach and prioritization
process in planning these types of projects, as described in the Rate Commission Third
Discovery Request (EXHIBIT MSD 63A-D). This approach is intended to ensure that the most
critically important projects are funded first, while projects without an anticipated potential for
near -term failure or that appear to have minor consequences of failure are not funded. Based on
the District's efforts to prioritize these projects, and the potential for NPDES permit violations
and negative environmental impacts at these facilities if these projects do not proceed, we do not

have discretion to delay these projects
REQUEST NO. 21: Concerning the District's financial model, on the tab "CIRP," the
source of new revenue bond issuances, please provide the following along with calculations on
electronic spreadsheet with formulas intact:
a. Please provide an explanation and support for the estimated amount of the line
"Revenue Bond Proceeds — Premium" used to estimate the source of additional funds
received from selling new bonds.
b. Please estimate the net interest cost to MSD using the "Revenue Bond
Proceeds — Par Amount" and "Revenue Bond Proceeds — Premium" amount assumptions in
its financial model for issuing new revenue bonds at a coupon rate of 5%, and issue cost rate
of 1%.
c. Please estimate the change in amounts of Revenue Bond Proceeds — Premium
from selling new bonds, if the net interest cost to MSD of new revenue bond issues,
reflecting a 5% coupon and 1% issue cost, would be 3.5%. That is, assume the MSD's 5%
coupon rate and 1% issue cost, then how much of Revenue Bond Proceeds — Premium would
be generated if the net cost of a new bond issue was 3.5%?
d. Please make the same estimate requested in c. above, but assume the net
interest cost to MSD would be 4%.
RESPONSE:
a. Bond premium is generated when a bond is sold with a coupon rate that is greater
than the market interest rate at the time of the sale. In order to compensate the issuer, or
borrower, for issuing bonds at a coupon rate higher than quoted market rates, the buyer of the
bonds, the investor, will pay the issuer a price that is higher than the face value, or par amount,
of the bonds. For example, if an investor paid $1,100 for a bond with a par value of $1, 000, the
bond premium is $100. The premium does not have to be paid back to the investor like the face
amount of the bonds is expected to be. Likewise, the interest due on the bonds is calculated by
multiplying the coupon rate by the par amount of the bonds, ignoring any premium received.
Premium bonds are currently standard in the tax-exempt municipal bond market. The benchmark
for rates in the tax-exempt municipal bond market is the AAA MMD yield curve.
It is important to note that most bonds are issued at yields higher than the quoted MMD
rates. This difference is called the spread and the size of the spread is dependent on a variety of
market and issuer factors. Essentially, investors have to determine how much they are willing to
pay for any issuer 's bonds and that is expressed in the yield they want to receive. The price of the
bond is determined by discounting the cash flows associated with the bond (a series of interest
payments plus the return of the par, or principal, amount) at the agreed upon yield rate. The
result is the price the investor is willing to pay the issuer for the bond. If that amount is greater
than the face value of the bond, the difference is the premium. If the principal payment is due
after the bond's call date, the calculation should assume early repayment of principal at the
optional call date. The call date is that date at which the bond may be prepaid early, at the
discretion of the issuer. A standard call period is at 10 years for a 30 year bond.

Exhibit MSD 78A
MSD's model assumes 30 year bonds with annual principal amortization. Each principal
amount has an assumed coupon rate and yield. These are shown in Exhibit MSD 78E. The price
of each principal amount in a series must be calculated to determine the premium amount for the
series. Exhibit MSD 78F is a model, with instructions, that can be used to estimate par and
premium given a desired total proceeds estimate and given coupon and yield rates. The model
will provide results immaterially different than MSD's Rate Proposal due to slightly different
assumptions made for this working model. The differences are shown in Exhibit MSD 78G.
b. The intervener asks for net interest cost but MSD does not evaluate its issuances
using net interest cost. Net interest cost was a measure created before the widespread use of
computers and does not take the time value of money into account. MSD does look at True
Interest Cost (TIC), which does factor in the time value of money and is an expression of the
issuer 's cost. It assumes the bonds will be repaid at maturity so it is a Yield to Maturity (YTM)
rate thus is not calculated the same way as the bond's Yield to Call (YTC) rate or the benchmark
MMD rate — reported benchmark rates are based on the assumption that bonds will be prepaid
at the call date, not at maturity. When discussing "yield" of a bond, markets are generally
referring to the expected return to the investor. The yield for callable premium bonds is a YTC,
not a YTM. Exhibit 78G - Debt Scenario Results lists the yield of each assumed issuance to keep
it on the same basis as the benchmark rates. The YTC is the discount rate at which the
discounted cash flows of the entire issuance are equal to the bond proceeds, assuming optional
prepayment of relevant principal payments at the call date. The TIC rate is also listed, as that is
the most common measure of the issuer 's cost. Again, though, TIC is a YTM rate and is not
calculated the same way as the YTC or the MMD rates. Please also note that MSD assumes that
some coupons will exceed 5.0% in FY22 — FY24. To see the impact of using 5.0% coupons with
the yields MSD has assumed, just change the appropriate inputs in the model and follow the
instructions.
c. Please see Exhibit MSD 78G. Again, the YTC and the TIC rate are presented
instead of the requested net interest cost. MSD does not evaluate its bond issuances using net
interest cost. Furthermore, neither MSD nor its financial advisors recommend using a flat yield
curve or a yield curve that does not provide a greater allowance for rates to rise over the next
five years.
d. Please see Exhibit MSD 78G. Again, the YTC and the TIC rate are presented
instead of the requested net interest cost. MSD does not evaluate its bond issuances using net
interest cost. Furthermore, neither MSD nor its financial advisors recommend using a flat yield
curve or a yield curve that does not provide a greater allowance for rates to rise over the next
five years.
