9. PENSION PLANS AND OTHER POSTRETIREMENT BENEFITS

Pension Plans

Spire and the Utilities maintain pension plans for their employees.

Spire Missouri and Spire Alabama have non-contributory, defined benefit, trusteed forms of pension plans covering the majority of their employees. Qualified plan assets are comprised of mutual and commingled funds consisting of U.S. equities with varying strategies, global equities, alternative investments, and fixed income investments.

The net periodic pension cost includes components shown in the following tables. The components other than the service costs and regulatory adjustment are presented in “Other Income, Net” in the income statement, except for Spire Alabama’s losses on lump-sum settlements. Such losses are capitalized in regulatory balances and amortized over the remaining actuarial life of individuals in the plan, and that amortization is presented in “Other Income, Net.”

Pursuant to the provisions of Spire Missouri’s and Spire Alabama’s pension plans, pension obligations may be satisfied by monthly annuities, lump-sum cash payments, or special termination benefits. Lump-sum payments are recognized as settlements (which can result in gains or losses) only if the total of such payments exceeds the sum of service and interest costs in a specific year. Special termination benefits, when offered, are also recognized as settlements which can result in gains or losses. For the three and six months ended March 31, 2024, no Spire plans met the criteria for settlement recognition.

For the six months ended March 31, 2023, two Spire Alabama plans met the criteria for settlement recognition. The lump-sum payments recognized as settlements for the remeasurement were $27.5 for the Spire Alabama plans. The lump-sum settlements resulted in a loss of $8.6 for Spire Alabama. The Spire Alabama regulatory tariff requires that settlement losses be amortized over the remaining actuarial life of the individuals in the plan — in this case, 13.4 years for one plan and 12.4 years for the other plan. Therefore, no lump sum settlement expense was recorded in the six months ended March 31, 2023.

Effective December 23, 2021, the pension cost for Spire Missouri’s western territory (“Missouri West”) included in customer rates was reduced from $5.5 to $4.4 per year, the pension cost included in Spire Missouri’s eastern territory (“Missouri East”) customer rates was increased from $29.0 to $32.4 per year. Subsequently, on December 26, 2022, the amount in Missouri East was lowered to $29.9. The difference between these amounts and pension expense as calculated pursuant to the above and that otherwise would be included in the statements of income and statements of comprehensive income is deferred as a regulatory asset or regulatory liability.

Also effective December 23, 2021, Missouri East prepaid pension assets and other postretirement benefits that were previously being included in rates at $21.6 per year for eight years were reduced to $11.0 per year, with the amortization period being reset for another eight years. Missouri West net liability for pension and other postretirement benefits that were previously reducing rates by $3.3 per year for eight years were reduced to a $1.1 reduction in rates per year, with the amortization period being reset for another eight years. Subsequently, on December 26, 2022, Missouri East amortization was lowered to $6.9 and Missouri West to a reduction of $0.8.

The funding policy of the Utilities is to contribute an amount not less than the minimum required by government funding standards, nor more than the maximum deductible amount for federal income tax purposes. Fiscal 2024 contributions to Spire Missouri’s pension plans through March 31, 2024 were $5.0 to the qualified trusts and none to non-qualified plans. Fiscal 2024 contributions to the Spire Alabama pension plans through March 31, 2024 were $5.4. Contributions totaling $16.6 to the qualified trusts of Spire Missouri’s pension plans are anticipated for the remainder of fiscal 2024. Contributions to Spire Alabama’s pension plans for the remainder of fiscal 2024 are anticipated to be $11.0.

Other Postretirement Benefits

Spire and the Utilities provide certain life insurance benefits at retirement. Spire Missouri plans provide for medical insurance after early retirement until age 65. For retirements prior to January 1, 2015, certain Spire Missouri plans provided medical insurance after retirement until death. The Spire Alabama plans provide medical insurance upon retirement until death for certain retirees depending on the type of employee and the date the employee was originally hired.

The net periodic postretirement benefit cost includes components shown in the following tables. The components other than the service costs and regulatory adjustment are presented in “Other Income, Net” in the income statement, except in the event Spire Alabama incurs losses on lump-sum settlements. Any such losses are capitalized in regulatory balances and amortized over the remaining actuarial life of individuals in the plan, and that amortization is presented in “Other Income, Net.”

Missouri and Alabama state laws provide for the recovery in rates of costs accrued pursuant to GAAP provided that such costs are funded through an independent, external funding mechanism. The Utilities have established Voluntary Employees’ Beneficiary Association (VEBA) and Rabbi Trusts as external funding mechanisms. The assets of the VEBA and Rabbi Trusts consist primarily of money market securities and mutual funds invested in stocks and bonds.

Effective December 23, 2021, the $8.6 allowance for recovery in rates for Spire Missouri’s postretirement benefit plans was discontinued. The difference between no recovery in rates and pension expense as calculated pursuant to the above and that otherwise would be included in the statements of income and statements of comprehensive income is deferred as a regulatory asset or regulatory liability. Effective with the resolution of the 2022 Missouri rate case in December 2022, net liabilities for postretirement benefits will reduce rates $0.9 and $0.1 per year for Missouri East and Missouri West, respectively.

The Utilities’ funding policy is to contribute amounts to the trusts equal to the periodic benefit cost calculated pursuant to GAAP as recovered in rates. There have been no contributions to the postretirement plans through March 31, 2024 for Spire Missouri or Spire Alabama, and none are expected to be required for the remainder of the fiscal year.
