AGENDA ITEM FOUR

MEMORANDUM

TO: Council of Bond Oversight

FROM: Andrew Messer, Deputy Treasurer for Debt Management

SUBJECT: Request for Provisional and Final Approval of $310,000,000 Taxable and Tax- Exempt Revenue Bonds, including Refunding and New Money Obligations and the Renewal of a $100,000,000 Revolving Credit Facility with the Federal Home Loan Bank of Topeka for the Oklahoma Housing Finance Agency's 2021 Single-Family Mortgage Program

DATE: February 25, 2021

Background

The Oklahoma Housing Finance Agency (the “OHFA”) is requesting authority to issue $310 million in taxable and tax-exempt obligations for its 2021 single-family mortgage bond program (the “2021 Program”). As detailed in OHFA’s application and as summarized on the next page, this requested authorization is expected to consist of up to $210 million of long-term Single- Family Mortgage Revenue Bonds, which is expected to be issued in several series and include both taxable and tax-exempt obligations. It will also include the renewal of a $100 million revolving credit facility with the Federal Home Loan Bank of Topeka. The OHFA Board granted final approval of the proposed 2021 Single-Family Program at its meeting on January 27, 2021.

Financing Proposal

It is expected that all bond issues and refundings will be sold through negotiation with the OHFA underwriting team or via private placement with the Federal Home Loan Bank or other government sponsored enterprises (or a combination designed to realize the lowest cost of funds).

The legal services providers and financial advisor for the 2021 Program were chosen by the OHFA Board. The firms chosen were Caine Mitter & Associates, New York as Financial Advisor; the Public Finance Law Group of Oklahoma City as Bond Counsel; Kutak Rock as Disclosure and Special Tax Counsel. The Bank of Oklahoma was selected as Trustee.

The OHFA has chosen underwriters for their 2021 single-family program, with the book- running underwriter being Bank of America/Merrill Lynch and JP Morgan and Raymond James selected as co-managers.

Pursuant to the “program” provisions of our Administrative Rules, the financing team selected can be used for any financing under the requested authorizations completed within one year from the date of the first issue.

Components of the proposed 2021 Program for which approval is requested are summarized as follows:

(1) Approximately $210 million of long term, fixed rate Single-Family Mortgage Revenue Bonds to continue funding OHFA’s Homeownership Loan Program: (2) Renewal of OHFA’s $100 million Revolving Credit Facility with the Federal Home Loan Bank of Topeka; and (3) Any other alternative products for retaining bonding authority approved by the Council of Bond Oversight.

The planned composition of the OHFA’s 2021 borrowing program is detailed below:

- Long-term, fixed-rate bonds (3 series of $70 million) $ 210,000,000 - Revolving credit facility 100,000,000 Total $ 310,000,000

Analysis

The OHFA is requesting financing authorization for its 2021 Program. If granted, this approval would be valid for 180 days. However, pursuant to 62 O.S. 695.9(B)(4), an applicant that has received issuance approval from the Council of Bond Oversight can request, and the Deputy Treasurer for Debt Management may grant, a single 180-day extension. An application for such extension must be requested at least five (5) business days prior to the expiration of the original approval. Due to the nature of their program, the OHFA typically requests an extension of their bonding authority to ensure continuous operations during each calendar year.

The requested financing includes virtually all of the program elements the OHFA uses to issue new money bonds and to execute current refundings. The refunding portion of the requested financing is used to recapture tax-exempt lending capacity. Estimated sale dates and costs of issuance for the various proposed transactions are detailed in attachments to the enclosed OHFA application.

The OHFA will require private activity bond allocation (“Cap”) for the majority of its 2021 Program. Provided below is a summary of Cap available to the OHFA at this time:

Private Activity Cap Summary for OHFA

Source Amounts

Volume Cap carried forward from 2018 (expires 12/2021) $ 186,940,720 Volume Cap carried forward from 2019 (expires 12/2022) 99,223,295 Volume Cap carried forward from 2020 (expires 12/2023) 190,740,977 Subtotal, tax-exempt bonding capacity carried forward $ 476,904,992 OHFA Pool, 2021 1 62,697,332 TOTAL $ 539,602,324 ______1 A portion of the State’s annual private activity cap is reserved for the OHFA. The amount for 2021 is shown. The OHFA can also request allocations from both the Consolidated Pool (beginning September 2nd and the Carryforward Pool (beginning December 20th).

OHFA’s issuance of tax-exempt mortgage revenue bonds also requires the approval of the Governor of the State of Oklahoma. That approval, historically, has been granted in a timely manner. OHFA had $237,743,197 single-family revenue bonds outstanding as of September 30, 2020.

The proposed issues do not constitute obligations of the State of Oklahoma and neither the full faith and credit nor the taxing power of the State are pledged.

Recommended Conditions

If the Council of Bond Oversight approves the OHFA request for sale of $310 million taxable and tax-exempt revenue bonds and other obligations, including the renewal of the $100 million revolving line of credit with the Federal Home Loan Bank of Topeka, the following conditions are recommended:

1) Receipt of Preliminary Official Statement prior to pricing;

2) Receipt of supporting documentation showing maturity schedule of proposed issue, how the schedule was determined (including interest rate assumptions), prior to pricing; and

3) Receipt of the final Official Statement prior to closing.

The components of the Plan include the following: (1) Up to $210,000,000 (not including premium) of long term Single Family Mortgage Revenue Bonds to continue funding the Agency's Homeownership Loan Program; (2) Renewal of OHFA's previously authorized $100,000,000 Revolving Credit Facility with the Federal Home Loan Bank of Topeka to facilitate the implementation and management of the 2020 Program Plan ; (3) Any other alternative product(s) for retaining bonding authority approved by the Council of Bond Oversight; and

OHFA expects to leverage its allocation of tax-exempt bonding capacity by: (1) Recycling loan principal repayments and prepayments from prior series of OHFA single family mortgage revenue bonds, subject to bond market conditions; and (2) Issuing varying portions of each bond series as taxable bonds, subject to acceptable market conditions, in order to assist more low and moderate income families obtain affordable mortgage loans to purchase homes.

Expected Bond Ratings. All long term bonds will be rated 'Aaa' by Moody's Investors Service based on their issuance as parity bonds under the Agency's Homeownership Loan Program Master Trust Indentures (1994, 2009 and 2018).

IIQUALITY A IV ARD WINNER Letter to Mr. Andrew Messer, State Bond Advisor January 7, 2021 Page 2

Borrower Uses of Mortgage Loans. Program Loans can be used for: • Purchase of an existing or newly constructed single family residence

Statutory Federally Designated Targeted Areas: To comply with the IRS Code, at least 20% of each Set-Asides Program Installment attributable to new allocations of State Volume Cap for Private Activity Bonds will be made available to fund loans in federally-designated Targeted Areas.

Continuous To enhance its ability to achieve certain Program goals, OHFA will commit to fund Origination Program Loans under its continuous rural origination policy to allow certain borrowers to Initiatives obtain a Program Loan reservation and funding commitment at any time during the term of the 2021 Program.

If bond proceeds are not immediately available to fund the purchase of these Loans, they will be funded on an interim basis either with OHFA reserves or with borrowings under OHFA's revolving credit facility with the Federal Home Loan Bank of Topeka ("FHLB").

The $210.000.000 Homeownership Loan Program Bonds will be long term, fixed rate or variable rate bonds issued on a parity basis under (1) OHFA's 2018 Homeownership Loan Program Master Trust Indenture, (2) OHFA's 2009 Homeownership Loan Program Master Trust Indenture, established in connection with the NIBP program, (3) OHFA's 1994 Homeownership Loan Program Master Trust Indenture or will be monthly pass-through bonds issued under one of the above mentioned indentures or a new indenture. A portion of each series may be issued as taxable bonds in order to further leverage the Agency's limited allocation under the State Private Activity Bond Volume Cap. In addition, an interest rate swap may be entered into with one of OHFA's underwriters to manage interest rate risk on variable rate bonds, if issued.

The $100,000.000 Revolving Credit Facility with the Federal Home Loan Bank of Topeka will provide OHFA with the capacity to borrow on favorable terms at a taxable rate of interest (either on a floating rate or fixed rate basis) as may be required to facilitate interim funding of mortgage loans in the form of mortgage-backed securities under the Homeownership Loan Program, pending issuance/conversion of long term MRBs to permanently finance those mortgage loans. It is contemplated that no individual borrowings under this Revolving Credit Facility will be outstanding for more than eighteen (18) months. OHFA may periodically sell mortgage-backed securities financed by the revolving credit facility in the secondary market if pricing is favorable or to manage interest rate risk. Bond Ratings. The Homeownership Loan Program Bonds are expected be rated "Aaa" by Moody's Investors Service.

Methods of Bond Sale. All or a portion of the Homeownership Loan Program Bonds are expected to be issued via negotiated public sale due to the expected inclusion of premium bonds, Planned Amortization Class (" PAC") bonds*, and/or monthly pass-throughs, which effectively preclude a cost-efficient sale via competitive bid.

Transaction Costs. All service provider fees and expense allowances are based on the results of a competitive RFP selection process conducted by OHFA staff and approved by the OHFA Board. All RFPs are reviewed by the State Bond Advisor prior to their release. As required, all bond issuance costs will be reviewed with and approved by the State Bond Advisor.

Attachment B to this Application provides estimated transaction costs for the Homeownership Loan Program Bonds. The estimated transaction costs shown are based off OHFA's most recent bond financing. The transaction costs relate to the three expected issues of mortgage revenue bonds of up to $70 million each in 2021. If any single series of bonds is issued in a greater or lesser amount, the total transaction costs are expected to be adjusted more or less proportionately, based on the then applicable fee schedules of service providers.

2021 Program Financing Team. The Agency's current financing team is listed in the Application. The two law firms providing bond counsel, disclosure counsel, special tax counsel and underwriter counsel services, as well as the financial advisor for the 2020 Program, were selected under the terms of a competitive RFP selection process completed in September 2020. The investment banking firms serving as managing underwriters, the trustee bank, master loan servicer and financial printer for the 2020 Program were selected under the terms of a competitive RFP selection process completed in November 2020.

Objective. The public purpose objective of the proposed Homeownership Loan Program bond transactions is as follows:

Promote homeownership by low and moderate income Oklahomans in all areas of the State through a network of participating lenders by offering mortgage loans with below-market interest rates and/or down payment and closing cost assistance payments to borrowers who are eligible under the IRS Code for a loan funded with proceeds of tax-exempt bonds.

Leveraging Bonding Capacity. OHFA's strategy is designed to leverage the limited amount of Private Activity Bond issuance authority available to OHFA by:

(a) Recycling principal repayments and prepayments of Program loans funded with the proceeds of prior series of bonds (subject to certain limitations imposed by the IRS Code); and (bl Issuing taxable bonds that require no State Volume Cap Allocation.

* Planned Amortization Class bonds, or "PAC" bonds, are structured with special redemption terms to provide investors with more predictable and stable repayment expectations over a wide range of loan prepayment assumptions. This feature allows a PAC bond to sell for a lower yield than a term bond having an average life that varies more directly with loan portfolio prepayments.

RE: $310,000,000 Single Family Mortgage Revenue Bonds, 2021 Program

Ladies and Gentlemen:

We have examined the Constitution and laws of the State of Oklahoma (the "State"), particularly Title 60 Oklahoma Statutes 2011, Sections 176 - 180.3, (the "Act") under authority of which the Oklahoma Housing Finance Agency (the "Agency") was created as a public trust for the use and benefit ofthe State, and the Trust Indenture dated as of May 1, 197 5, (as amended and restated in a Second Amended Trust Indenture dated as of November 4, 1986, and amended and restated by the Third Amended Trust Indenture having the effective date of August 19, 2002). We have also examined copies of certain proceedings to be adopted by the Agency relating to the issuance of revenue notes or bonds (the "Bonds"), both tax-exempt and taxable, for the purpose of financing single family homes in an amount not to exceed $310,000,000 (which includes $100,000,000 for interim line of credit funding). In addition, we have examined such other documents and instruments as we have deemed necessary to express the opinions hereinafter set forth.

Each issue of Bonds will be issued pursuant to a resolution adopted by the Agency (the "Authorizing Bond Resolution") and a supplemental bond indenture or similar security document between the Agency and a trustee bank (the "Trustee"), dated as of the first day of the month of delivery (together with the Agency's base Bond Indenture, the "Indenture").

Based upon such examinations, under present Oklahoma and federal laws (which exclude any pending legislation which may have a retroactive effect on or before the date hereof), rulings and decisions, it is our opinion that:

(a) The Agency is a validly existing public trust and as such an agency of the State and a regularly constituted authority of the State for the performance of the functions for which the Agency

t 405 .235.3413 • f 405-235.2807 5657 N. CLASSEN BOULEVARD, SUITE 100 • OKLAHOMA CITY, OK 73n8 was created, with powers, among others, to issue and sell the Bonds, to use the proceeds thereof as indicated and to execute and deliver the Indenture to secure the Bonds.

(b) The Bonds can be duly and validly executed and delivered by the Agency under the base Bond Indenture and upon authentication by the Trustee, the Bonds will be valid and binding obligations of the Agency payable in accordance with their terms and secured by and entitled to the benefits provided by the Indenture. The Bonds will be special obligations of the Agency payable solely from the sources set forth in the Indenture.

(c) Each Indenture will constitute a valid pledge of the properties and rights securing the Bonds and will be validly assigned and pledged to the Trustee.

( d) The Bonds will not be general obligations or indebtedness of the Agency within the meaning of any constitutional or statutory limitation, and will not give rise to a pecuniary liability of the Agency or a charge against its general credit or taxing powers, but will be payable solely from revenues and other sums irrevocably pledged to the payment thereof pursuant to the Indenture.

(e) Interest on the tax-exempt portion of the Bonds will be excludible from the gross income of the owner thereof for federal income tax purposes pursuant to Section 103 of the Internal Revenue Code of 1986, as amended (the "Code"). The tax exempt Bonds will be qualified mortgage bonds within the meaning of Section 143 of the Code.

(f) Interest on the Bonds exempt from federal income tax will be also exempt from State of Oklahoma income tax.

(g) To our knowledge, there is no litigation pending which will affect the issuance of the Bonds or require disclosure with respect thereto.

At this time, we express no opinion as to any other federal tax consequences caused by the ownership or receipt or accrual of interest on the Bonds.

The enforceability of the Bonds and the Indenture may be limited by state and federal laws, rulings and decisions affecting remedies and by bankruptcy, reorganization, moratorium or other laws relating to or affecting creditors' rights heretofore or hereafter enacted to the extent constitutionally applicable, and their enforcement also may be subject to exercise of judicial discretion.

AGENDA ITEM FIVE

MEMORANDUM

TO: Council of Bond Oversight

FROM: Andrew Messer, Deputy Treasurer for Debt Management

SUBJECT: Request from the Oklahoma Municipal Power Authority for Provisional and Final Approval to execute a federally taxable Power Supply System Revenue Note in an amount not to exceed $60 million.

DATE: February 25, 2021

Background

The Oklahoma Municipal Power Authority (the “OMPA”) is requesting approval to execute a federally taxable bank loan directly placed with Bank of America in an amount not to exceed $60 million. The bank note proceeds will be utilized to provide financing for fuel supply costs incurred due to severe cold weather experienced February 8th-19th.

The historic winter storm that plunged the southern plains into below freezing temperatures for nearly two weeks resulted in an unforeseen spike in natural gas prices. The record cold not only drove up demand for natural gas, it also reduced supply as production was literally frozen in some cases. In order to provide uninterrupted electric service to its customers, OMPA was forced to purchase natural gas on the spot market as prices spiked to record levels hitting $600 per million btu’s.

While OMPA was successful in keeping electrical service on throughout the duration of the winter storm, the cost of the natural gas purchased far exceeded reserves available to make payment to suppliers when settlement occurs in mid-March. As a result, OMPA is seeking financing in the form of a bank note placed with Bank of America to pay its gas suppliers. The exact amount of the note has not been determined at this point, but it will not exceed $60 million and will not have a duration exceeding five years.

The OMPA was created by statute in 1981 and began operations as a power supplier on July 1, 1985. The Authority consists of thirty-nine (39) member cities and provides power from a variety of resources including wind, hydro, natural gas and coal.

Financing Plan

The Authority is leveraging its existing relationship with Bank of America, which provides a line of credit to the Authority, to negotiate a fixed rate loan that can be closed before the Authority is required to submit payment to its suppliers in mid-March. The Authority’s financial advisor, Hilltop Securities, is leading the negotiations in consultation with the Treasurer’s Office to obtain the most favorable terms for the borrowing. While a final agreement has not been executed, the note is expected to be structured with a five-year term to maturity, including an optional pre- payment provision, at a fixed interest rate of 1.46%.

The OMPA board authorized the execution of the bank note in an amount not to exceed $60 million at a special meeting held Friday February 19, 2021.

Analysis

The note will be issued under a supplemental resolution to the Authority’s 1985 Power Supply System Revenue Bond Resolution. Pursuant to the 1985 Resolution, the Authority is required to set an annual budget to the trustee setting forth, in detail, estimated revenues and expenses to ensure sufficient funds are available to pay all expenses including debt service1. Further, the Authority is required to establish and collect rates such that net revenues provide at least 1.1X aggregate debt service coverage2. The Authority has maintained coverage in excess of the 1.1X floor since the inception of the 1985 Resolution and in fiscal year 2020 debt service coverage was 1.22X3.

The note will be issued in parity with the Authority’s outstanding debt. A table showing the Authority’s outstanding obligations is provided in appendix I.

The proceeds of the bank note will be utilized to pay natural gas suppliers. Adjustments in rates for customers will be necessary to cover the cost of the acute crisis. As mentioned above the Authority will be required to increase rates in an amount sufficient to provide in excess of 1.1X coverage..

The proposed bank note is not an obligation of the State of Oklahoma and, neither the full faith and credit, nor the taxing power of the State are pledged to the repayment of this obligation.

1) Receipt of the form of the legal opinion from bond counsel prior to pricing;

2) Receipt of the approved supplemental resolution authorizing the borrowing of not to exceed $60 million.

1 NOTICE OF MATERIAL EVENT FOR CONTINUING DISCLOSURE REQUIREMENTS OF SEC RULE 15c2-12 February 22, 2021

This Notice is being provided voluntarily by the Oklahoma Municipal Power Authority (the “Issuer”), pursuant to the requirement of Rule 15c2-12 (the “Rule”) of the Securities and Exchange Commission Act of 1934, as notification of occurrence of the following event as defined in paragraph (b)(5)(i)(C) of the Rule.

As a result of the recent extreme cold weather in the Southwestern United States commencing February 13, 2021, Oklahoma Municipal Power Authority (the “Authority”) was required by the Southwest Power Pool to run all available power generation for reliability of the electric grid. Widespread blackouts were avoided and the Authority satisfied the electric power needs of all its member cities throughout the period of extreme cold weather, and expects to continue to satisfy such power needs. In doing so it purchased additional gas to generate the needed electric power and was exposed to and incurred higher than normal gas costs due to the unusual demand for power caused by the extreme cold. This was exacerbated by a shortage of natural gas in the region due to significant wellhead freeze- offs. While the net cost of such gas and payments from the RTO will not be known for several weeks, the Authority is exploring its options, including borrowing an amount that it does not currently expect to exceed $60 million, to ensure its ability to satisfy its obligations while maintaining a minimum of 100 days cash on hand.
