EMPLOYEE BENEFIT PLANS

11. EMPLOYEE BENEFIT PLANS

Pension and Other Postemployment Benefit Plans

The Company has two trusteed, noncontributory defined benefit retirement plans covering eligible regular represented and non-represented employees with more than one year of service. Defined benefit plan benefits are based on years of service and average compensation during the highest 60 consecutive months of employment. The Company also provides postemployment medical and life insurance benefits to employees who meet certain eligibility requirements.

All represented employees of NJRHS hired on or after October 1, 2000, non-represented employees hired on or after October 1, 2009 and NJNG represented employees hired on or after January 1, 2012 are covered by an enhanced defined contribution plan instead of the defined benefit plan. Participation in the postemployment medical and life insurance plan was also frozen to new employees as of the same dates, with the exception of new NJRHS represented employees, for which benefits were frozen beginning April 3, 2012.

The Company maintains an unfunded nonqualified PEP that was established to provide employees with the full level of benefits as stated in the qualified plan without reductions due to various limitations imposed by the provisions of federal income tax laws and regulations. There are no plan assets in the nonqualified plan due to the nature of the plan.

The Company’s funding policy for its pension plans is to contribute at least the minimum amount required by the Employee Retirement Income Security Act of 1974, as amended. In fiscal 2022 and 2021, the Company had no minimum funding requirements and did not make any discretionary contributions to the pension plans. The Company does not expect to be required to make additional contributions to fund the pension plans during the next fiscal year based on current actuarial assumptions; however, funding requirements are uncertain and can depend significantly on changes in actuarial assumptions, returns on plan assets and changes in the demographics of eligible employees and covered dependents.

There are no federal requirements to pre-fund OPEB benefits. However, the Company is required to fund certain amounts due to regulatory agreements with the BPU. The Company contributed $6.1 million and $7.2 million in fiscal 2022 and 2021, respectively, and estimates that it will contribute between $5 million and $10 million over each of the next five years. Additional contributions may be required based on market conditions and changes to assumptions.

The Affordable Care Act was enacted in March 2010 and created an excise tax applicable to high-cost health plans, commonly known as the Cadillac Tax. Beginning in 2022, employers who sponsor health plans that have an annual cost that exceeded an amount defined by the law pay a 40 percent tax on the excess plan costs. The 2020 federal spending package permanently eliminated the Affordable Care Act-mandated Cadillac tax on high-cost employer-sponsored health coverage. Due to the repeal, the Company’s OPEB liability was revalued for these changes. The Company applied a practical expedient to remeasure the plan assets and obligations as of December 31, 2019, which was the nearest calendar month-end date. The impact of the revaluation of the OPEB liability was recorded as of January 1, 2020 and is incorporated within actuarial assumptions at September 30, 2020.

The following summarizes the changes in the funded status of the plans and the related liabilities recognized on the Consolidated Balance Sheets as of September 30:

(2)Employees hired prior to July 1, 1998, that were eligible to elect an additional participant contribution to enhance their benefits, and contributions made during the periods were immaterial.

The actuarial gains on the Company’s pension and OPEB are due primarily to an increase in the discount rate used to measure the benefit obligation. The Company recognizes a liability for its underfunded benefit plans as required by ASC 715, Compensation - Retirement Benefits. The Company records the offset to regulatory assets for the portion of liability relating to NJNG and to accumulated OCI for the portion of the liability related to its unregulated operations.

The following table summarizes the amounts recognized in regulatory assets and accumulated OCI as of September 30:

	Regulatory Assets				Accumulated Other Comprehensive Income (Loss)
	Pension		OPEB		Pension		OPEB

Amounts arising during the period:
Net actuarial (gain)	(39,006)		(16,286)		(7,036)		(76)
Amounts amortized to net periodic costs:

The amounts in regulatory assets and accumulated OCI not yet recognized as components of net periodic benefit cost as of September 30 are:

	Regulatory Assets								Accumulated Other Comprehensive Income (Loss)
	Pension				OPEB				Pension				OPEB
(Thousands)	2022		2021		2022		2021		2022		2021		2022		2021

To the extent the unrecognized amounts in accumulated OCI or regulatory assets exceed 10 percent of the greater of the benefit obligation or the fair value of plan assets, an amortized amount over the average expected future working lifetime of the active plan participants is recognized. Amounts included in regulatory assets and accumulated OCI expected to be recognized as components of net periodic benefit cost in fiscal 2023 are as follows:

	Regulatory Assets				Accumulated Other Comprehensive Income (Loss)
(Thousands)	Pension		OPEB		Pension		OPEB
Net actuarial (gain) loss	$	(36)	$	—	$	217	$	—

Assumptions

The weighted average assumptions used to determine the Company’s benefit costs during the fiscal years below and obligations as of September 30, are as follows:

	Pension									OPEB
	2022			2021			2020			2022			2021			2020

(1)Percentages for represented and non-represented plans, respectively.

When measuring its PBO, the Company uses an aggregate discount rate at which its obligation could be effectively settled. The Company determines a single weighted average discount rate based on a yield curve comprised of rates of return on a population of high quality debt issuances (AA- or better) whose cash flows (via coupons or maturities) match the timing and amount of its expected future benefit payments. The Company measures its service and interest costs using a disaggregated, or spot rate, approach. The Company applies the duration-specific spot rates from the full yield curve, as of the measurement date, to each year’s future benefit payments, which aligns the timing of the plans’ separate future cash flows to the corresponding spot rates on the yield curve.

Information relating to the assumed HCCTR used to determine expected OPEB benefits as of September 30, and the effect of a 1 percent change in the rate, are as follows:

($ in thousands)	2022		2021		2020
HCCTR	6.6%		6.9%		7.6%
Ultimate HCCTR	4.5%		4.5%		4.5%
Year ultimate HCCTR reached	2027		2027		2026
Effect of a 1 percentage point increase in the HCCTR on:
Year-end benefit obligation	$	26,710	$	43,217	$	49,106
Total service and interest cost	$	2,544	$	2,959	$	2,799
Effect of a 1 percentage point decrease in the HCCTR on:
Year-end benefit obligation	$	(21,853)	$	(34,669)	$	(38,844)
Total service and interest costs	$	(1,966)	$	(2,253)	$	(2,151)

The Company’s investment objective is a long-term real rate of return on assets before permissible expenses that is approximately 5 percent greater than the assumed rate of inflation, as measured by the consumer price index. The expected long-term rate of return is based on the asset categories in which the Company invests and the current expectations and historical performance for these categories.

The mix and targeted allocation of the pension and OPEB plans’ assets are as follows:

	2023		Assets at
	Target		September 30,
Asset Allocation	Allocation		2022		2021
U.S. equity securities	34	%	32	%	36	%
International equity securities	17		16		17
Fixed income	33		32		40
Collective investment trusts at NAV	16		20		7
Total	100	%	100	%	100	%

The Company adopted the revised mortality assumptions published by the Society of Actuaries for its pension and other postemployment benefit obligations, which reflected increased life expectancies in the U.S. The adoption of the new mortality projection scale, MP-2021 and the Pri-2012 mortality study, did not materially impact the projected benefit obligation for the plans.

The following benefit payments, which reflect expected future service, as appropriate, are expected to be paid during the following fiscal years:

(Thousands)	Pension		OPEB
2023	$	14,112	$	6,878
2024	$	15,143	$	7,508
2025	$	16,150	$	8,220
2026	$	17,137	$	8,938
2027	$	18,104	$	9,656
2028 - 2032	$	104,614	$	57,488

The Company’s OPEB plans provide prescription drug benefits that are actuarially equivalent to those provided by Medicare Part D. Therefore, under the Medicare Prescription Drug, Improvement and Modernization Act of 2003, the Company qualifies for federal subsidies.

The following estimated subsidy payments are expected to be paid during the following fiscal years:

	Estimated Subsidy

The Plan had no Level 2 or Level 3 fair value measurements during fiscal 2022 and 2021, and there have been no changes in valuation methodologies as of September 30, 2022. The Plan held assets that are valued using NAV as a practical expedient, which are excluded from the fair value hierarchy.

The following is a description of the valuation methodologies used for assets measured at fair value:

Money Market funds — Represents bank balances and money market funds that are valued based on the NAV of shares held at year end.

Registered Investment Companies — Equity and fixed income funds valued at the NAV of shares held by the plan at year end as reported on the active market on which the individual securities are traded.

Collective investment trusts — The NAV for collective investment trusts is provided by the Trustee and is used as a practical expedient to estimate fair value. The NAV is based on the value of the underlying assets owned by the fund less liabilities.

The methods described above may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Furthermore, while the Plan believes its valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date.

Defined Contribution Plan

The Company offers a Savings Plan to eligible employees. The Company matches 85 percent of participants’ contributions up to 6 percent of base compensation. Represented NJRHS employees, non-represented employees hired on or after October 1, 2009, and NJNG represented employees hired on or after January 1, 2012, are eligible for an employer special contribution of between 3.5 percent and 4.5 percent of base compensation, depending on years of service, into the Savings Plan on their behalf. The amount expensed and contributed for the matching provision of the Savings Plan was $5.5 million in fiscal 2022, $5.1 million in fiscal 2021 and $4.5 million in fiscal 2020. The amount contributed for the employer special contribution of the Savings Plan was $2.4 million in fiscal 2022, $2.1 million in fiscal 2021 and $1.6 million in fiscal 2020.
