Pay vs Performance Disclosure |  |  |  |
Pay vs Performance Disclosure, Table | Pay Versus Performance Pursuant to the SEC’s pay versus performance (“PVP”) disclosure rules, the following Pay Versus Performance table (“PVP Table”) provides SEC-required information about compensation for fiscal 2024 for this Proxy Statement’s named executive officers, as well as compensation for fiscal 2023, fiscal 2022 and fiscal 2021 for our named executive officers from our 2024, 2023 and 2022 Proxy Statements, respectively (each of fiscal 2021, 2022, 2023 and 2024, a “Covered Year”). We refer to all of the named executive officers covered in the PVP Table below, collectively, as the “PVP NEOs.” The PVP Table also provides information about the results for certain measures of financial performance during those same Covered Years. In reviewing this information, there are a few important things we believe you should consider:
| • |  | The information in columns (b) and (d) of the PVP Table comes directly from our Summary Compensation Tables for the relevant years, without adjustment;
| • |  | As required by the SEC’s PVP rules, we label the information in columns (c) and (e) of the PVP Table as “compensation actually paid” (or “CAP”) to the applicable PVP NEOs. However, these CAP amounts do not necessarily reflect “take home pay” or the final compensation that our PVP NEOs actually earned or walked away with for their service in the Covered Years. Instead, the SEC’s concept of CAP reflects a combination of realized pay and realizable or accrued pay; and
| • |  | As required by the SEC’s PVP rules, we provide information in the PVP Table below about our cumulative absolute total shareholder return (“TSR”) results, cumulative TSR results for two peer groups of companies identified in the PVP Table, and our U.S. GAAP net income results (the “External Measures”) during the Covered Years. We did not, however, actually base any compensation decisions for the PVP NEOs on, or link any PVP NEO pay to, these particular External Measures because the External Measures were not metrics used in our short-term or long-term incentive plans during the Covered Years. In particular, the index-based peer groups used for purposes of this PVP Table disclosure are different from the specific group of companies against which we evaluate relative TSR performance for our named executive officers for purposes of our TSR performance share awards, as described above in our Compensation Discussion and Analysis. As a result, we did not necessarily design our PVP NEO compensation to move in tandem with any improving, declining or steady achievement in these External Measures.

(1) | David P. Bauer was our principal executive officer (“PEO”) for the full year for each of fiscal 2024, 2023, 2022 and 2021. For fiscal 2024, our non-PEO PVP NEOs are Timothy J.

(3) | For each Covered Year, our absolute TSR was calculated as the yearly percentage change in our cumulative TSR on our Common Stock, measured as the quotient of (a) the sum of (i) the cumulative amount of dividends for a period beginning with our closing price on the NYSE on September 30, 2020 through and including the last day of the Covered Year (each one-year, two-year, three-year and four-year period, a “Measurement Period”), assuming dividend reinvestment, plus (ii) the difference between our closing stock price at the end versus the beginning of the Measurement Period, divided by (b) our closing share price at the beginning of the Measurement Period. Each of these yearly percentage changes was then applied to a deemed fixed investment of $100 at the beginning of the Measurement Period to produce the Covered Year-end values of such investment as of the end of fiscal 2024, 2023, 2022 and 2021, as applicable. Because Covered Years are presented in the table in reverse chronological order (from top to bottom), the table should be read from bottom to top for purposes of understanding cumulative returns over time.
(4) | For purposes of this PVP disclosure, our peer groups are the S&P Mid Cap 400 Gas Utility Index (column (g1)) and the S&P 1500 Oil & Gas Exploration & Production Index (column (g2)) (each, a “Peer Group”). For each Covered Year, Peer Group cumulative TSR was calculated based on a deemed fixed investment of $100 through the Measurement Period, assuming dividend reinvestment for the Peer Group.
(5) | Net income is the amount reported in the Company’s audited financial statements for the applicable year, calculated in accordance with U.S. GAAP.
(6) | For purposes of this PVP disclosure, consolidated EBITDA is calculated as operating income plus depreciation, depletion and amortization, plus any period-end impairment charges, excluding the effect of tax code amendments and regulatory responses thereto that impact EBITDA, any reversal of reserves for preliminary survey and investigation charges recorded in a prior fiscal year, and the impact any joint development agreement, restructuring, reorganization, acquisition, disposition, or winding down of any business unit.
