BOARD RECOMMENDATION:
On November 17, 2025, the Board of Public Utilities received the annual update on the Riverside Public Utilities Fiscal and Cash Reserve Policy and voted unanimously to approve and recommend the City Council approve the updated Riverside Public Utilities Fiscal and Cash Reserve Policy to establish the Section 115 Pension Trust – Unfunded Accrued Liability Reserve, include the approved Water Treatment Reserve (water fund only), and to clarify certain existing policy definitions.
BACKGROUND:
Policy History
On December 18, 2015, and March 22, 2016, the Board of Public Utilities (Board) recommended approval and the City Council approved the Cash Reserve Policy. On May 23, 2016, and July 26, 2016, the Board recommended approval and the City Council approved the existing Riverside Public Utilities (RPU) Fiscal Policies, which incorporated the Cash Reserve Policy in Appendix A. The approved policies documented and adopted financial goals for both the water and electric utilities and established policies for long-term, as well as day-to-day operations of both utilities. The policies cover a number of areas including: financial reporting, cash reserves, operating and capital budgeting, debt management, investments, risk management, financial planning, and others.
On January 10, 2017, the City Council adopted the City’s existing Debt Management Policy to satisfy the requirements of Senate Bill (SB) 1029.
On May 22, 2017 and July 11, 2017, the Board and City Council approved the Dark Fiber Leasing Program, which included establishing uniform lease rates for the use of the dark fiber infrastructure, physical and cyber security policies, a master fiber lease license agreement, and a new cost center within the Electric Fund for related expenses and revenue with an appropriation of $1,800,000 for the dark fiber program construction and management activities. The Board and City Council also approved the transfer of $1,800,000 to a new dark fiber designated reserve to fund leased fiber activities.
On May 22, 2018, the City Council approved rates that include the use of a Line of Credit (LOC) as part of the 5-Year Rate proposal to keep utility rates as low as possible. Utilizing a LOC reduced the electric and water rates by approximately 1% and 3%, respectively. A LOC is a low-cost financial tool available to entities with strong credit ratings that provide flexibility and operating liquidity similar to cash reserves if there is an emergency need. The LOC allows RPU to reduce the rate impact to customers by enabling RPU to spend cash reserves on capital projects while the LOC is used in lieu of cash to meet the overall liquidity and reserve levels necessary to maintain RPU’s strong bond ratings.
On June 25, 2018 and July 24, 2018, the Board recommended approval and City Council approved the updated RPU Fiscal Policies and Cash Reserve Policy, which included providing a reference and link to the City’s Debt Management Policy within the RPU Fiscal Policies to comply with Senate Bill 1029, removing the separate appendix for a RPU Debt Management Policy, including the Dark Fiber Designated Reserve in the Cash Reserve Policy, and adding the use of the LOC to the Cash Reserve Policy.
On November 9, 2020, the Board received an update on the RPU Cash Reserve Policy, funds, and use of funds. At this meeting, the Board requested a comparative analysis of RPU’s cash reserve policies and the credit ratings compared to other similarly sized utility organizations in the region, as well as an analysis of potential impacts of the Covid-19 pandemic to RPU’s cash reserve.
On July 26, 2021, and September 7, 2021, the Board recommended approval and City Council approved the updated RPU Fiscal Policies and Cash Reserve Policy. Updates included:
The addition of designated reserves for the Electric Fund for additional decommissioning liability to reflect the increase in annual funds for the San Onofre Nuclear Generating Station (SONGS) Additional Decommissioning Liability Reserve from $1.6M to $2.0M annually; The removal of the calculation of operating and maintenance expenses from the Undesignated Reserves for Working Capital; The revision of calculation to include a three-year average for Undesignated Reserves for System Improvement Capital; The removal of capital improvement expenditures funded with restricted or designated reserves from Undesignated Reserves for System Improvement Capital; and Updated definitions to simplify reserve terminology.
On January 10, 2022, the Board received an introduction on how RPU uses bond financing and the role of the fiscal policy.
At the August 8, 2022, Board meeting, Chair Crohn created an ad hoc committee consisting of Chair Peter Wohlgemuth and Members Nancy Melendez, Gary Montgomery, and Gil Oceguera to:
Review and evaluate the Public Utilities Department and the City fiscal policies related to the use of bond financing to fund internal staff labor used to design, construct, and administer capital projects; and Report back to the Board by November 30, 2022.
On September 26, 2022, at the Board meeting, Ad Hoc Committee Chair Wohlgemuth provided the Board with an update on the committee progress and discussed the need to extend the November 30, 2022, reporting deadline to January 2023.
On May 8, 2023, the Board received a report from the Ad Hoc Committee regarding the committee’s review, evaluation, and recommended changes to fiscal policies related to the use of bond financing to funding internal staff labor used to design, construct, and administer capital projects. After the discussion with the Ad Hoc Committee, the Board did not make recommendations to change the fiscal policies.
On June 26, 2023, the Board received an update on the RPU Cash Reserve Policy, as it related to the Water and Electric Five-Year Rate plans.
On June 24, 2024, and August 6, 2024, the Board and City Council received and approved an update on the RPU Cash Reserve Policy to reduce the annual funding to the San Onofre Nuclear Generating Station Additional Decommissioning Liability Reserve from $2.0M to $1.0, beginning in fiscal year 2024/25.
On September 8, 2025 and November 17, 2025, the Board recommended approval and City Council approved establishing a Water Treatment Designated Reserve to set aside proceeds from PFAS settlements to fund capital costs for water treatment plants.
DISCUSSION:
Reserve Policies Purpose
Properly designed reserve policies send a positive signal to ratepayers, investors, and regulatory and credit rating agencies that the Board and City Council are committed to maintaining the long-term fiscal strength of RPU. Strong and transparent financial policies, including maintaining prudent reserves for emergencies, rate stability, working capital, capital improvements, and debt service, are consistent with best practices in the utility industry and are important to RPU as they help to:
Maintain the short-term and long-term financial health of RPU.
Maintain stable rates for customers and help ensure manageable rate increases.
Fund unanticipated cost contingencies.
Ensure funds exist for system improvements.
Ensure cash exists for the timely payment of bills.
Act as a significant positive credit factor in bond ratings.

RPU will use designated reserves to mitigate the impacts of known and impending exposures. The withdrawal and replenishment of Council/Board-approved designated reserves and their allowable uses will be tracked individually, but the specific use of designated reserves falls outside the scope of this policy and is subject to Board and Council approval.
Undesignated Reserves are the remaining unrestricted reserves that may be used for any lawful purpose and have not been designated for specific capital and operating purposes. However, maintaining a proper level of undesignated reserves is critical to ensure the utility can meet its fluctuating cashflow demands and mitigate financial volatility. The following Undesignated Reserve Policy addresses the levels, use, and replenishment of this type of unrestricted reserves.
Undesignated Reserve Policy
RPU will have sufficient undesignated reserves to maintain or improve its credit ratings, ensure that operating and maintenance costs will be paid in a timely manner, pay debt service obligations, and invest in needed capital improvements and equipment replacement on a timely basis. In addition, RPU will maintain sufficient reserves to minimize rate increases due to market volatility, weather impacts on demands, emergencies (such as natural disasters), and regulatory changes.
The Policy provides minimum and maximum levels of undesignated reserves. Each of the areas of undesignated reserves include considerations for evaluation to determine the appropriate reserve levels. RPU maintains such monies pooled in each utility’s undesignated reserve. These reserve allocations are consistent with industry standards for similarly rated electric and water utilities. Each component of the reserves is sized at less than the maximum possible exposure for each component because it is unlikely several of the risks each enterprise faces would materialize simultaneously.

Debt Service
Ensures the ability to make debt service payments in an extreme event that may impact RPU’s ability to provide services, thus impacting revenues at a time critical infrastructure repairs are needed to restore systems. The Debt Service Reserve is intended to prevent an event where RPU would be unable to pay its debt service obligations during such emergencies or extreme market disruptions.
X
X
Withdrawal and Replenishment of Reserves
RPU treats the targeted reserves as practical minimums and allows reserves to increase or decrease as necessary within the minimum and maximum prescribed levels.
To the extent that undesignated reserves plus the LOC, if applicable, are above the target and below the maximum, the Board and City Council have the flexibility to direct staff to utilize those available funds to pay for capital projects (reducing the need for future debt), pay down unfunded liabilities, such as pension obligations, defease outstanding debt, or fund other strategic objectives. No other action by RPU would be required if reserves are between the minimum and maximum level unless directed by the Board and City Council.
If reserve funds exceed the maximum level, RPU would seek Board and City Council approval to use the excess to finance capital improvements on a pay-as-you-go basis, pay down existing debt, offset other long-term liabilities, such as pension obligations, reduce rates, or fund other strategic initiatives.
Reserve levels below the minimum targeted reserves will leave RPU exposed to significant operational risks. Should RPU draw down reserves below the minimum targeted level, RPU will implement plans to return reserves to their minimum targeted levels within three years. Such plans will be provided within 12 months.
Reporting and Oversight
Reserve levels are monitored throughout the fiscal year and reported in the monthly and quarterly financial reports. Reserve target (minimum) and maximum levels are analyzed annually, and an over/under-reserve determination is made in conjunction with year-end financial results. These results are reported to the Board and City Council as part of the year-end financial report presentation. Should designated or undesignated reserve levels need adjustment due to new risk factors due to changes in the industry, these will be brought to the Board and City Council as part of the year-end report.
The Policy is to be reviewed annually and updated (at a minimum of every three years) if there are material changes in the risk exposures or new conditions that require changes in reserve levels.

Electric Undesignated Reserve
The five-year electric utility rate plan funds future operating and capital costs, maintains reserve levels and financial metrics that comply with RPU’s fiscal and reserve policies, and maintains current bond ratings to keep borrowing costs for capital investments low. In order to keep the rate increases in the five-year electric rate plan as low as possible, the undesignated reserve balance combined with the LOC does fall below minimum target reserve levels prior to returning to above-minimum target reserve levels within the three-year timeframe required by the reserve policy.

Water Undesignated Reserve
The five-year water utility rate plan funds future operating and capital costs, maintains reserve levels and financial metrics that comply with RPU’s fiscal and reserve policies, and maintains current bond ratings to keep borrowing costs for capital investments low. In order to keep the rate increases in the five-year water rate plan as low as possible, the undesignated reserve balance combined with the LOC meets minimum target reserve levels required by the reserve policy.
