Fitch Ratings -Austin – 22 Feb 2024: Fitch Ratings has affirmed the ‘AAA’ rating on the following obligations issued by the Moulton Niguel Water District, CA (the district):

–$124.7 million certificates of participation (COPs) series 2019 and 2021;

–$56.6 million revenue refunding bonds series 2019.

Additionally, Fitch has affirmed the district’s Issuer Default Rating at ‘AAA.’ The Rating Outlook is Stable.

Moulton Niguel Water District (CA)/Water & Sewer Revenues/1 LTLT AAA Rating Outlook Stable AffirmedAAA Rating Outlook Stable

The ‘AAA’ COPs, revenue bond rating and ‘AAA’ IDR reflect the district’s ‘Exceptionally Strong’ financial profile in the context of its ‘Very Strong’ revenue defensibility, assessed at ‘aa’. The ratings also reflect the ‘Strong’ operating risk profile assessed at ‘a’. The district’s leverage, measured as net adjusted debt to adjusted funds available for debt service (FADS), was extremely low at 3.9x in fiscal 2023 and is expected to peak at 4.6x in fiscal 2025 in Fitch’s Analytical Stress Test (FAST) stress case.

However, leverage should generally trend down in the following years to a level supported by the current rating. Should the district fail to recognize the declining leverage trend, and FADS growth does not adequately support the new debt, the rating may face pressure.

SECURITY

The COPs (under an installment purchase agreement) and the bonds are secured by net revenues of the district’s water, recycled water and sewer systems, including property tax revenues.

KEY RATING DRIVERS

Revenue Defensibility – ‘aa’

Very Favorable Service Area, Affordable Rates for the Vast Majority of the Population

The district retains the legal authority to adjust rates as needed without external oversight. Fitch considers the monthly residential water and sewer bill affordable for approximately 94% of the service area population based on standard monthly usage of 7,500 gallons for water and 6,000 gallons for sewer. The very favorable service area is characterized by very strong income levels, a moderate unemployment rate relative to the nation and midrange customer growth.

With a largely built-out service area, the district has recently seen little to no growth in the customer bases as reflected in the five-year compound annual growth rate of 0% as of fiscal 2023. Income levels are about 81% above the national median as of 2022. The unemployment rate was 14% below the national average in 2022.

Operating Risk – ‘a’

Low Operating Cost Burden, Elevated Investment Needs, Supported by Adequate Capital Investment

In fiscal 2023, the system’s operating cost burden was considered low at $8,865 per million gallons (mg), consistent with the operating risk assessment. The life cycle ratio is elevated at 49% in fiscal 2023. Capex to depreciation has been strong, reflected in the five-year average of 175% from fiscal 2019 to fiscal 2023. Planned capital spending for the next five years should generally outpace historical depreciation, resulting in a stable to improving life cycle ratio.

The district’s adopted capital improvement plan (ClP) for fiscal 2024 through 2028 totals

$336 million and reflects a comprehensive list of projects. However, management expects actual capital spending to be lower and closer to a 60% execution rate, which has been included in the FAST analysis. The ClPis largely focused on repair and rehabilitation projects with a smaller portion of spending expected on regional projects completed in conjunction with South Orange County Wastewater Authority (SOCWA).

Debt financing is likely to account for between 35% and 40% of funding sources. The balance will be primarily funded on a pay-go basis, with grant monies providing a modest funding source, as well. Currently the district expects to receive nearly $12 million in grant money within the next one to two years.

Financial Profile – ‘aaa’

Exceptionally Strong Financial Profile

The district had extremely low leverage of 3.9x as of fiscal 2023. Over the last several years leverage generally trended higher, peaking at 4.6x in fiscal 2022 with the last debt issuance, but otherwise has registered below 4.0x each year. The upward trend is a result of additional debt over this period in conjunction with generally flat FADS. The liquidity profile is neutral to the overall assessment with current days cash on hand of 144 and coverage of full obligations (COFO) of 2.1x. Fitch-calculated total debt service coverage was 3.0x in fiscal 2023, which excludes fixed service expense.

The FAST considers the potential trend of key ratios in a base case and stress case over a five-year period. The stress case is designed to impose capital costs 10% above expected base case levels and evaluate potential variability in projected key ratios. The FAST reflects Fitch’s view of a reasonable scenario, which is generally informed by publicly available and/or management provided information with respect to capital expenditures, user charges and rate of revenue and expenditure growth.

In the base case scenario, the leverage ratio is projected to increase to 4.4x in fiscal 2025, then decrease to 3.5x through fiscal 2028. In the stress case, the leverage ratio is expected to increase to 4.6x in fiscal 2025, then decline to 3.9x through fiscal 2028. Liquidity is expected to remain neutral to the assessment over the five-year horizon.

Asymmetric Additional Risk Considerations

No asymmetric additive risk considerations affected this rating determination.

RATING SENSITIVITIES

Factors that Could, Individually or Collectively, Lead to Negative Rating Action/Downgrade

–Sustained actual and projected leverage exceeding 4.0x in Fitch’s base and stress case, assuming stability in the revenue defensibility and operating risk assessments.

Factors that Could, Individually or Collectively, Lead to Positive Rating Action/Upgrade

The ratings are at the highest level on Fitch’s scale and cannot be upgraded.

PROFILE

The district provides water, wastewater and recycled water services to approximately 171,000 residents in southern Orange County, CA (IDR AAA/Stable). Encompassing 37 square miles, the district’s service area includes the cities of Aliso Viejo, Laguna Niguel, significant portions of Laguna Hills and Mission Viejo, and small portions of Dana Point and San Juan Capistrano.

The district is a customer agency of the Municipal Water District of Orange County (MWDOC). MWDOC purchases treated and untreated water from the Metropolitan Water District of Southern California (IDR AA+/Stable). Around 80% of the district’s supply is provided through purchased water and the balance is provided by the district’s recycled water system. Based on the current supply portfolio the district has adequate supply through at least 2045.

The district continues to work toward increasing recycled water production and supply redundancy. The district is also a member of the SOCWA. Through this regional partnership, the district owns about 22.7 million gallons per day (mgd) capacity in four wastewater treatment facilities, and utilizes three of the treatment facilities to process approximately 11 mgd of wastewater.

ESG CONSIDERATIONS

The highest level of ESG credit relevance is a score of ‘3’, unless otherwise disclosed in this section. A score of ‘3’ means ESG issues are credit-neutral or have only a minimal credit impact on the entity, either due to their nature or the way in which they are being managed by the entity. Fitch’s ESG Relevance Scores are not inputs in the rating process; they are an observation on the relevance and materiality of ESG factors in the rating decision.

Please read these limitations and disclaimers by following this link: https://www.fitchratings.com/understandingcreditratings. In addition, the following https://www.fitchratings.com/rating-definitions-document details Fitch’s rating definitions

for each rating scale and rating categories, including definitions relating to default. ESMA and the FCA are required to publish historical default rates in a central repository in accordance with Articles 11(2) of Regulation (EC) No 1060/2009 of the European Parliament and of the Council of 16 September 2009 and The Credit Rating Agencies (Amendment etc.) (EU Exit) Regulations 2019 respectively.

Published ratings, criteria, and methodologies are available from this site at all times. Fitch’s code of conduct, confidentiality, conflicts of interest, affiliate firewall, compliance, and other relevant policies and procedures are also available from the Code of Conduct section of this site. Directors and shareholders’ relevant interests are available at https://www.fitchratings.com/site/regulatory. Fitch may have provided another permissible or ancillary service to the rated entity or its related third parties. Details of permissible or ancillary service(s) for which the lead analyst is based in an ESMA- or FCA-registered Fitch Ratings company (or branch of such a company) can be found on the entity summary page for this issuer on the Fitch Ratings website.

In issuing and maintaining its ratings and in making other reports (including forecast information), Fitch relies on factual information it receives from issuers and underwriters and from other sources Fitch believes to be credible. Fitch conducts a reasonable investigation of the factual information relied upon by it in accordance with its ratings methodology, and obtains reasonable verification of that information from independent sources, to the extent such sources are available for a given security or in a given jurisdiction. The manner of Fitch’s factual investigation and the scope of the third-party verification it obtains will vary depending on the nature of the rated security and its issuer, the requirements and practices in the jurisdiction in which the rated security is offered and sold and/or the issuer is located, the availability and nature of relevant public information, access to the management of the issuer and its advisers, the availability of pre-existing third-party verifications such as audit reports, agreed-upon procedures letters, appraisals, actuarial reports, engineering reports, legal opinions and other reports provided by third parties, the availability of independent and competent third- party verification sources with respect to the particular security or in the particular jurisdiction of the issuer, and a variety of other factors. Users of Fitch’s ratings and reports should understand that neither an enhanced factual investigation nor any third-party verification can ensure that all of the information Fitch relies on in connection with a rating or a report will be accurate and complete. Ultimately, the issuer and its advisers are responsible for the accuracy of the information they provide to Fitch and to the market in offering documents and other reports. In issuing its ratings and its reports, Fitch must rely on the work of experts, including independent auditors with respect to financial statements and attorneys with respect to legal and tax matters. Further, ratings and forecasts of financial and other information are inherently forward-looking and embody assumptions and predictions about future events that by their nature cannot be verified as facts. As a result, despite any verification of current facts, ratings and forecasts can be affected by future events or conditions that were not anticipated at the time a rating or forecast was issued or affirmed. Fitch Ratings makes routine, commonly-accepted adjustments to reported financial data in accordance with the relevant criteria and/or industry standards to provide financial metric consistency for entities in the same sector or asset class.

The complete span of best- and worst-case scenario credit ratings for all rating categories ranges from ‘AAA’ to ‘D’. Fitch also provides information on best-case rating upgrade scenarios and worst-case rating downgrade scenarios (defined as the 99th percentile of rating transitions, measured in each direction) for international credit ratings, based on historical performance. A simple average across asset classes presents best-case upgrades of 4 notches and worst-case downgrades of 8 notches at the 99th percentile. Sector­ specific best- and worst-case scenario credit ratings are listed in more detail at https://www.fltchratings.com/site/re/10238496

The information in this report is provided “as is” without any representation or warranty of any kind, and Fitch does not represent or warrant that the report or any of its contents will meet any of the requirements of a recipient of the report. A Fitch rating is an opinion as to the creditworthiness of a security. This opinion and reports made by Fitch are based on established criteria and methodologies that Fitch is continuously evaluating and updating. Therefore, ratings and reports are the collective work product of Fitch and no individual, or group of individuals, is solely responsible for a rating or a report. The rating does not address the risk of loss due to risks other than credit risk, unless such risk is specifically mentioned. Fitch is not engaged in the offer or sale of any security. All Fitch reports have shared authorship. Individuals identified in a Fitch report were involved in, but are not solely responsible for, the opinions stated therein. The individuals are named for contact purposes only. A report providing a Fitch rating is neither a prospectus nor a substitute for the information assembled, verified and presented to investors by the issuer and its agents in connection with the sale of the securities. Ratings may be changed or withdrawn at any time for any reason in the sole discretion of Fitch. Fitch does not provide investment advice of any sort. Ratings are not a recommendation to buy, sell, or hold any security. Ratings do not comment on the adequacy of market price, the suitability of any security for a particular investor, or the tax-exempt nature or taxability of payments made in respect to any security. Fitch receives fees from issuers, insurers, guarantors, other obligors, and underwriters for rating securities. Such fees generally vary from US$1,000 to US$750,000 (or the applicable currency equivalent) per issue. In certain cases, Fitch will rate all or a number of issues issued by a particular issuer, or insured or guaranteed by a particular insurer or guarantor, for a single annual fee. Such fees are expected to vary from US$10,000 to US$1,500,000 (or the applicable currency equivalent). The assignment, publication, or dissemination of a rating by Fitch shall not constitute a consent by Fitch to use its name as an expert in connection with any registration statement filed under the United States securities laws, the Financial Services and Markets Act of 2000 of the United Kingdom, or the securities laws of any particular jurisdiction.
