Rates are determined by depreciation studies, which are required to be performed at least every 5 years on the regulated utility assets of Roanoke Gas.

As a result, the Company accrues the estimated cost of retirement of its utility plant through depreciation expense and creates a corresponding regulatory liability. The costs of retirement considered in the development of the depreciation component include those costs associated with the legal liability. Therefore, the ARO is reclassified from the regulatory cost of retirement obligation. If the legal obligations were to exceed the regulatory liability provided for in the depreciation rates, the Company would establish a regulatory asset for such difference with the anticipation of future recovery through rates charged to customers.

The following table sets forth the benefit obligation, fair value of plan assets, the funded status of the plans, and amounts recognized in the Company’s consolidated financial statements: Pension Plan Postretirement Plan 2023 2022 2023 2022 Accumulated benefit obligation $ 24,449,856 $ 24,776,968 $ 11,248,448 $ 12,416,546 Change in benefit obligation: Benefit obligation at beginning of year $ 27,268,456 $ 37,654,468 $ 12,416,546 $ 16,796,849 Service cost 366,537 648,289 45,897 97,802 Interest cost 1,372,098 1,013,115 620,622 443,721 Actuarial gain (1,031,160 ) (10,862,957 ) (1,331,541 ) (4,330,387 ) Benefit payments, net of retiree contributions (1,228,307 ) (1,184,459 ) (503,076 ) (591,439 ) Benefit obligation at end of year $ 26,747,624 $ 27,268,456 $ 11,248,448 $ 12,416,546 Change in fair value of plan assets: Fair value of plan assets at beginning of year $ 28,017,797 $ 38,914,107 $ 12,138,119 $ 15,882,342 Actual return on plan assets, net of taxes 89,171 (9,711,851 ) 1,384,270 (3,152,784 ) Employer contributions — — — — Benefit payments, net of retiree contributions (1,228,307 ) (1,184,459 ) (503,076 ) (591,439 ) Fair value of plan assets at end of year $ 26,878,661 $ 28,017,797 $ 13,019,313 $ 12,138,119 Funded status $ 131,037 $ 749,341 $ 1,770,865 $ (278,427 ) Amounts recognized in the consolidated balance sheet consist of: Non-current assets $ 131,037 $ 749,341 $ 1,770,865 $ — Non-current liabilities — — — (278,427 ) Amounts recognized in accumulated other comprehensive income: Net actuarial loss, net of tax $ 1,168,687 $ 1,243,889 $ 6,946 $ 355,088 Total amounts included in accumulated other comprehensive income, net of tax $ 1,168,687 $ 1,243,889 $ 6,946 $ 355,088 Amounts deferred to a regulatory asset (liability): Net actuarial loss (gain) $ 4,029,282 $ 4,132,472 $ (1,813,071 ) $ (30,118 ) Amounts recognized as regulatory assets (liabilities) $ 4,029,282 $ 4,132,472 $ (1,813,071 ) $ (30,118 ) The Company expects that approximately $64,000, before tax, of AOCI will be recognized in net periodic benefit costs in fiscal 2024 2024. The reduction in the benefit obligations for both the pension plan and postretirement plan was primarily attributed to actuarial gains resulting from the increase in the discount rate used to calculate the benefit obligations. The following table details the actuarial assumptions used in determining the projected benefit obligations and net benefit cost of the pension plan and the accumulated benefit obligations and net benefit cost of the postretirement plan: Pension Plan Postretirement Plan 2023 2022 2023 2022 Assumptions used to determine benefit obligations: Discount rate 5.63 % 5.15 % 5.63 % 5.16 % Expected rate of compensation increase 4.00 % 4.00 % N/A N/A Assumptions used to determine benefit costs: Discount rate 5.15 % 2.73 % 5.16 % 2.70 % Expected long-term rate of return on plan assets 4.50 % 4.75 % 3.95 % 4.24 % Expected rate of compensation increase 4.00 % 4.00 % N/A N/A To develop the expected long-term rate of return on plan assets assumption, the Company, with input from the Plans' actuaries and investment advisors, considered the historical returns and the future expectations for returns for each asset class, as well as the target asset allocation of each plan’s portfolio. Components of net periodic benefit cost are as follows: Pension Plan Postretirement Plan 2023 2022 2023 2022 Service cost $ 366,537 $ 648,289 $ 45,897 $ 97,802 Interest cost 1,372,098 1,013,115 620,622 443,721 Expected return on plan assets (1,232,597 ) (1,831,550 ) (464,046 ) (666,167 ) Recognized loss 316,724 146,402 — — Net periodic benefit cost $ 822,762 $ (23,744 ) $ 202,473 $ (124,644 ) Service cost is included in operations and maintenance expense in the consolidated statements of income. All other components of net periodic benefit costs are included in other income, net in the consolidated statements of income. The assumed health care cost trend rates used in measuring the accumulated benefit obligation for the postretirement plan are presented below: Pre 65 Post 65 2023 2022 2023 2022 Health care cost trend rate assumed for next year 6.30 % 6.00 % 5.20 % 5.20 % Rate to which the cost trend is assumed to decline (the ultimate trend rate) 3.94 % 5.20 % 3.94 % 5.20 % Year that the rate reaches the ultimate trend rate 2075 2025 2075 2022 The health care cost trend rate assumptions could have a significant effect on the amounts reported. A change of 1% 1% Increase 1% Decrease Effect on total service and interest cost components $ 89,000 $ (74,000 ) Effect on accumulated postretirement benefit obligation 1,317,000 (1,117,000 ) The primary objectives of both plans' investment policies are to maintain investment portfolios that diversify risk through prudent asset allocation parameters, achieve asset returns that meet or exceed the corresponding actuarial assumptions and will provide for future benefits. The Company's pension plan allocation approach seeks to match the duration of the fixed income portion of the portfolio with the duration of the plan's liabilities. Such allocation is designed to reduce the overall volatility in the pension plan relative to the funded status. In fiscal 2023, Based on its most recent evaluation of returns for the asset classes within each plan's investment portfolio, the Company set the expected long-term rate of return for the pension plan and the postretirement plan for fiscal 2024 The Company’s target and actual asset allocation in the pension and postretirement plans as of September 30, 2023 2022 Pension Plan Postretirement Plan Target 2023 2022 Target 2023 2022 Asset category: Equity securities 25 % 27 % 13 % 30 % 43 % 48 % Debt securities 75 % 72 % — % 70 % 37 % 51 % Cash — % 1 % 87 % — % 20 % 1 % The plans assets are invested in mutual funds and common and collective investment trust ("CIT") funds that function like mutual funds.

Payments are made based on a predetermined monthly volume with the price based on the weighted average first September 30, 2023 2022 first The Company’s non-financial assets and liabilities that are measured at fair value on a nonrecurring basis consist of its AROs. The AROs are measured at fair value at initial recognition based on expected future cash flows to settle the obligation. The carrying value of cash and cash equivalents, accounts receivable, borrowings under line-of-credit, accounts payable (with the exception of the timing difference under the asset management contract), customer credit balances and customer deposits is a reasonable estimate of fair value due to the short-term nature of these financial instruments. In addition, the carrying amount of the variable rate line-of-credit is a reasonable approximation of its fair value.

Asset Retirement Obligation [Policy Text Block] | Asset Retirement Obligations 410, Asset Retirement and Environmental Obligations The Company’s composite depreciation rates include a component to provide for the cost of asset retirement. As a result, the Company accrues the estimated cost of retirement of its utility plant through depreciation expense and creates a corresponding regulatory liability. The costs of retirement considered in the development of the depreciation component include those costs associated with the legal liability. Therefore, the ARO is reclassified from the regulatory cost of retirement obligation. If the legal obligations were to exceed the regulatory liability provided for in the depreciation rates, the Company would establish a regulatory asset for such difference with the anticipation of future recovery through rates charged to customers. In 2022, The following is a summary of the AROs: Years Ended September 30 2023 2022 Beginning balance $ 10,204,079 $ 7,628,958 Liabilities incurred 91,670 236,926 Liabilities settled (180,865 ) (131,763 ) Accretion 677,947 397,692 Revisions to estimated cash flows — 2,072,266 Ending balance $ 10,792,831 $ 10,204,079 |
