National Fuel Gas Company

Notes to Condensed Consolidated Financial Statements

(Unaudited)

Note 1 – Summary of Significant Accounting Policies

Principles of Consolidation.  The Company consolidates all entities in which it has a controlling financial interest.  All significant intercompany balances and transactions are eliminated. The Company uses proportionate consolidation when accounting for drilling arrangements related to oil and gas producing properties accounted for under the full cost method of accounting.

The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period.  Actual results could differ from those estimates.

Earnings for Interim Periods.  The Company, in its opinion, has included all adjustments (which consist of only normally recurring adjustments, unless otherwise disclosed in this Form 10-Q) that are necessary for a fair statement of the results of operations for the reported periods. The consolidated financial statements and notes thereto, included herein, should be read in conjunction with the financial statements and notes for the years ended September 30, 2019, 2018 and 2017 that are included in the Company's 2019 Form 10-K.  The consolidated financial statements for the year ended September 30, 2020 will be audited by the Company's independent registered public accounting firm after the end of the fiscal year.

The earnings for the three months ended December 31, 2019 should not be taken as a prediction of earnings for the entire fiscal year ending September 30, 2020.  Most of the business of both the Utility segment and the Company's NFR operations (included in the All Other category) is seasonal in nature and is influenced by weather conditions.  Due to the seasonal nature of the heating business in the Utility segment and in the Company's NFR operations, earnings during the winter months normally represent a substantial part of the earnings that those businesses are expected to achieve for the entire fiscal year.  The Company’s business segments are discussed more fully in Note 9 — Business Segment Information.

Consolidated Statements of Cash Flows.  The components, as reported on the Company’s Consolidated Balance Sheets, of the total cash, cash equivalents, and restricted cash presented on the Statement of Cash Flows are as follows (in thousands):

	Three Months Ended   December 31, 2019				Three Months Ended   December 31, 2018
	Balance at October 1, 2019		Balance at December 31, 2019		Balance at October 1, 2018		Balance at December 31, 2018
Cash and Temporary Cash Investments	$	20,428	$	34,966	$	229,606	$	109,754
Hedging Collateral Deposits	6,832		9,666		3,441		2,784
Cash, Cash Equivalents, and Restricted Cash	$	27,260	$	44,632	$	233,047	$	112,538

The Company considers all highly liquid debt instruments purchased with a maturity date of generally three months or less to be cash equivalents. The Company’s restricted cash is composed entirely of amounts reported as Hedging Collateral Deposits on the Consolidated Balance Sheets. Hedging Collateral Deposits is an account title for cash held in margin accounts funded by the Company to serve as collateral for hedging positions. In accordance with its accounting policy, the Company does not offset hedging collateral deposits paid or received against related derivative financial instruments liability or asset balances.

Gas Stored Underground.  In the Utility segment, gas stored underground is carried at lower of cost or net realizable value, on a LIFO method.  Gas stored underground normally declines during the first and second quarters of the year and is replenished during the third and fourth quarters.  In the Utility segment, the current cost of replacing gas withdrawn from storage is recorded in the Consolidated Statements of Income and a reserve for gas replacement is recorded in the Consolidated Balance Sheets under the caption “Other Accruals and Current Liabilities.”  Such reserve, which amounted to $1.1 million at December 31, 2019, is reduced to zero by September 30 of each year as the inventory is replenished.

Property, Plant and Equipment.  In the Company’s Exploration and Production segment, oil and gas property acquisition, exploration and development costs are capitalized under the full cost method of accounting. Under this methodology, all costs associated with property acquisition, exploration and development activities are capitalized, including internal costs directly identified with acquisition, exploration and development activities. The internal costs that are capitalized do not include any costs

11

related to production, general corporate overhead, or similar activities. The Company does not recognize any gain or loss on the sale or other disposition of oil and gas properties unless the gain or loss would significantly alter the relationship between capitalized costs and proved reserves of oil and gas attributable to a cost center. The Company's capitalized costs relating to oil and gas producing activities, net of accumulated depreciation, depletion and amortization, were $1.7 billion at both December 31, 2019 and September 30, 2019.

Capitalized costs include costs related to unproved properties, which are excluded from amortization until proved reserves are found or it is determined that the unproved properties are impaired.  Such costs amounted to $57.9 million and $53.5 million at December 31, 2019 and September 30, 2019, respectively.  All costs related to unproved properties are reviewed quarterly to determine if impairment has occurred. The amount of any impairment is transferred to the pool of capitalized costs being amortized.

Capitalized costs are subject to the SEC full cost ceiling test. The ceiling test, which is performed each quarter, determines a limit, or ceiling, on the amount of property acquisition, exploration and development costs that can be capitalized. The ceiling under this test represents (a) the present value of estimated future net cash flows, excluding future cash outflows associated with settling asset retirement obligations that have been accrued on the balance sheet, using a discount factor of 10%, which is computed by applying prices of oil and gas (as adjusted for hedging) to estimated future production of proved oil and gas reserves as of the date of the latest balance sheet, less estimated future expenditures, plus (b) the cost of unevaluated properties not being depleted, less (c) income tax effects related to the differences between the book and tax basis of the properties. The gas and oil prices used to calculate the full cost ceiling are based on an unweighted arithmetic average of the first day of the month oil and gas prices for each month within the twelve-month period prior to the end of the reporting period. If capitalized costs, net of accumulated depreciation, depletion and amortization and related deferred income taxes, exceed the ceiling at the end of any quarter, a permanent impairment is required to be charged to earnings in that quarter.  At December 31, 2019, the ceiling exceeded the book value of the oil and gas properties by approximately $59.1 million. In adjusting estimated future cash flows for hedging under the ceiling test at December 31, 2019, estimated future net cash flows were increased by $9.1 million.

In August 2017, the FASB issued authoritative guidance which changes the financial reporting of hedging relationships to better portray the economic results of an entity's risk management activities and to simplify the application of hedge accounting.

12

The Company adopted this authoritative guidance effective October 1, 2019, recognizing a cumulative effect adjustment that decreased retained earnings by $1.0 million and increased accumulated other comprehensive income by the same amount.

In January 2016, the FASB issued authoritative guidance regarding the recognition and measurement of financial assets and liabilities. The authoritative guidance primarily affects the accounting for equity investments and the presentation and disclosure requirements for financial instruments. All equity investments in unconsolidated entities will be measured at fair value through earnings rather than through accumulated other comprehensive income. The Company adopted this authoritative guidance effective October 1, 2018 and, as called for by the modified retrospective method of adoption, recorded a cumulative effect adjustment during the quarter ended December 31, 2018 to increase retained earnings by $7.4 million and decrease accumulated other comprehensive income by the same amount.

Reclassifications Out of Accumulated Other Comprehensive Loss.  The details about the reclassification adjustments out of accumulated other comprehensive loss for the three months ended December 31, 2019 and 2018 are as follows (amounts in parentheses indicate debits to the income statement) (in thousands):

Earnings Per Common Share.  Basic earnings per common share is computed by dividing income or loss by the weighted average number of common shares outstanding for the period. Diluted earnings per common share reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock.  For purposes of determining earnings per common share, the potentially dilutive securities the Company had outstanding were SARs, restricted stock units and performance shares.  For the quarter ended December 31, 2019, the diluted weighted average shares outstanding shown on the Consolidated Statements of Income reflects the potential dilution as a result of these securities as determined using the Treasury Stock Method.  SARs, restricted stock units and performance shares that are antidilutive are excluded from the calculation of diluted earnings per common share. There were 733,617 securities and 318,106 securities excluded as being antidilutive for the quarter ended December 31, 2019 and December 31, 2018 respectively.

Stock-Based Compensation.  The Company granted 254,608 performance shares during the quarter ended December 31, 2019. The weighted average fair value of such performance shares was $43.32 per share for the quarter ended December 31, 2019. Performance shares are an award constituting units denominated in common stock of the Company, the number of which may be adjusted over a performance cycle based upon the extent to which performance goals have been satisfied.  Earned performance shares may be distributed in the form of shares of common stock of the Company, an equivalent value in cash or a combination of cash and shares of common stock of the Company, as determined by the Company. The performance shares do not entitle the participant to receive dividends during the vesting period.

Half of the performance shares granted during the quarter ended December 31, 2019 must meet a performance goal related to relative return on capital over a three-year performance cycle.  The performance goal over the performance cycle is the Company’s total return on capital relative to the total return on capital of other companies in a group selected by the Compensation Committee (“Report Group”).  Total return on capital for a given company means the average of the Report Group companies’ returns on capital for each twelve month period corresponding to each of the Company’s fiscal years during the performance cycle, based on data reported for the Report Group companies in the Bloomberg database.  The number of these performance shares that will vest and be paid will depend upon the Company’s performance relative to the Report Group and not upon the absolute level of return achieved by the Company.  The fair value of these performance shares is calculated by multiplying the expected number of shares that will be issued by the average market price of Company common stock on the date of grant reduced by the present value of forgone dividends over the vesting term of the award.  The fair value is recorded as compensation expense over the vesting term of the award.  The other half of the performance shares granted during the quarter ended December 31, 2019 must meet a performance goal related to relative total shareholder return over a three-year performance cycle.  The performance goal over the performance cycle is the Company’s three-year total shareholder return relative to the three-year total shareholder return of the other companies in the Report Group.  Three-year total shareholder return for a given company will be based on the data reported for that company (with the starting and ending stock prices over the performance cycle calculated as the average closing stock price for the prior calendar month and with dividends reinvested in that company’s securities at each ex-dividend date) in the Bloomberg database.  The number of these total shareholder return performance shares ("TSR performance shares") that will vest and be paid will depend upon the Company’s performance relative to the Report Group and not upon the absolute level of return achieved by the Company.  The fair value price at the date of grant for the TSR performance shares is determined using a Monte Carlo simulation technique, which includes a reduction in value for the present value of forgone dividends over the vesting term of the award.  This price is multiplied by the number of TSR performance shares awarded, the result of which is recorded as compensation expense over the vesting term of the award.

The Company granted 150,839 nonperformance-based restricted stock units during the quarter ended December 31, 2019.  The weighted average fair value of such nonperformance-based restricted stock units was $40.38 per share for the quarter ended December 31, 2019.  Restricted stock units represent the right to receive shares of common stock of the Company (or the

14

equivalent value in cash or a combination of cash and shares of common stock of the Company, as determined by the Company) at the end of a specified time period. These nonperformance-based restricted stock units do not entitle the participant to receive dividends during the vesting period. The accounting for nonperformance-based restricted stock units is the same as the accounting for restricted share awards, except that the fair value at the date of grant of the restricted stock units must be reduced by the present value of forgone dividends over the vesting term of the award.

Note 2 – Revenue from Contracts with Customers

The Company adopted authoritative guidance regarding revenue recognition on October 1, 2018 using the modified retrospective method of adoption for open contracts as of October 1, 2018. A cumulative effect adjustment to retained earnings was not necessary since no revenue recognition differences were identified when comparing the revenue recognition criteria under the new authoritative guidance to the previous guidance. The Company records revenue related to its derivative financial instruments in the Exploration and Production segment as well as in its NFR operations (included in the All Other category). The Company also records revenue related to alternative revenue programs in its Utility segment. Revenue related to derivative financial instruments and alternative revenue programs are excluded from the scope of the new authoritative guidance since they are accounted for under other existing accounting guidance.

The following tables provide a disaggregation of the Company's revenues for the three months ended December 31, 2019 and 2018, presented by type of service from each reportable segment. As reported in the Company's 2019 Form 10-K, the Company's NFR operations were previously reported as the Energy Marketing segment, however the Company is no longer reporting the energy marketing operations as a separate reportable segment. Prior year disaggregation of revenue information shown below has been restated to reflect this change in presentation.

The Company’s Pipeline and Storage segment expects to recognize the following revenue amounts in future periods related to “fixed” charges associated with remaining performance obligations for transportation and storage contracts: $125.6 million for the remainder of fiscal 2020; $148.7 million for fiscal 2021; $121.8 million for fiscal 2022; $87.6 million for fiscal 2023; $77.4 million for fiscal 2024; and $318.6 million thereafter.

Note 3 – Leases

On October 1, 2019, the Company adopted authoritative guidance regarding lease accounting, which requires entities that lease the use of property, plant and equipment to recognize on the balance sheet the assets and liabilities for the rights and obligations created by all leases, including leases classified as operating leases. The Company implemented the new standard using the optional transition method and elected to apply the following practical expedients provided in the authoritative guidance:

1. For contracts that commenced prior to and existed as of October 1, 2019, a package of practical expedients to not reassess whether a contract is or contains a lease, lease classification, and initial direct costs under the new authoritative guidance;

2. An election not to apply the recognition requirements in the new authoritative guidance to short-term leases (a lease that at commencement date has a lease term of one year or less);

3. A practical expedient to not reassess certain land easements that existed prior to October 1, 2019 and were not previously accounted for as leases under the prior authoritative guidance; and

4. A practical expedient that permits combining lease and non-lease components in a contract and accounting for the combination as a lease (elected by asset-class).

Upon adoption, the Company increased assets and liabilities on its Consolidated Balance Sheet by $19.7 million. The adoption did not result in a cumulative effect adjustment to earnings reinvested in the business or have a material impact on the Company’s Consolidated Statement of Income or Consolidated Statement of Cash Flows. Comparative periods, including disclosures relating to those periods, were not restated.

16

Nature of Leases

The Company primarily leases building space and drilling rigs, and on a limited basis compressor equipment and other miscellaneous assets. The Company determines if an arrangement is a lease at the inception of the arrangement. To the extent that an arrangement represents a lease, the Company classifies that lease as an operating or a finance lease in accordance with the authoritative guidance. As of December 31, 2019, the Company did not have any finance leases. Aside from a sublease of office space at the Company’s corporate headquarters, the Company does not have any material arrangements where the Company is the lessor.

Buildings and Property

The Company enters into building and property rental agreements with third parties for office space, certain field locations and other properties used in the Company’s operations. Building and property leases include the Company’s corporate headquarters in Williamsville, New York, and Exploration and Production segment offices in Houston, Texas, and Pittsburgh, Pennsylvania. The primary non-cancelable terms of the Company’s building and property leases range from six months to eleven years. Most building leases include one or more options to renew, generally at the Company’s sole discretion, with renewal terms that can extend the lease terms from one year to fourteen years. Renewal options are included in the lease term if they are reasonably certain to be exercised. The agreements do not contain any material restrictive covenants.

Drilling Rigs

The Company enters into contracts for drilling rig services with third party contractors to support Seneca’s development activities in Pennsylvania and California. Seneca’s drilling rig arrangements are structured with a non-cancelable primary term of one year or less. Upon mutual agreement with the contractor, Seneca has the option to extend the contract with amended terms and conditions, including a renegotiated day rate fee.

The Company has strategically entered into shorter-term drilling rig arrangements to allow for operational and financial flexibility to respond to changes in its operating and economic environment. The Company uses discretion in choosing to extend or not extend drilling rig contracts on a rig by rig basis depending on market and operating conditions present at the time the contract expires, including prices for natural gas and oil.

Due to these considerations, the Company concluded that it is not reasonably certain that it will elect to extend any of its drilling rig arrangements beyond their primary non-cancelable terms of one year or less. Consequently, the Company’s drilling rig leases are deemed to be short-term leases subject to the exemption for balance sheet recognition. These costs are capitalized as part of oil and natural gas properties on the Consolidated Balance Sheet when incurred.

Significant Judgments

Lease Identification

The Company uses judgment when determining whether or not an arrangement is or contains a lease. A contract is or contains a lease if the contract conveys the right to use an explicitly or implicitly identified asset that is physically distinct and the Company has the right to control the use of the identified asset for a period of time. When determining right of control, the Company evaluates whether it directs the use of the asset and obtains substantially all of the economic benefits from the use of the asset.

Discount Rate

The Company uses a discount rate to calculate the present value of lease payments in order to determine lease classification and measurement of the lease asset and liability. In the absence of a rate of interest that is readily determinable in the contract, the Company estimates the incremental borrowing rate (IBR) for each lease. The IBR reflects the rate of interest that the Company would pay on the lease commencement date to borrow an amount equal to the lease payments on a collateralized basis over a similar term in similar economic environments.

Firm Transportation and Storage Contracts

The Company’s subsidiaries enter into long-term arrangements to both reserve firm transportation capacity on third party pipelines and provide firm transportation and storage services to third party shippers. The Company’s firm capacity contracts with non-affiliated entities do not provide rights to use substantially all of the underlying pipeline or storage asset. As such, the Company has concluded that these arrangements are not leases under the authoritative guidance.

17

Oil and Gas Leases

The new authoritative guidance does not apply to leases to explore for or use minerals, oil or natural gas resources, including the right to explore for those natural resources and rights to use the land in which those natural resources are contained. As such, the Company has concluded that its oil and gas exploration and production leases and gas storage leases are not leases under the authoritative guidance.

Amounts Recognized in the Financial Statements

Operating lease costs, excluding those relating to short-term drilling rig leases that are capitalized as part of oil and natural gas properties under full cost pool accounting, are presented in Operations and Maintenance expense on the Consolidated Statement of Income. The following table summarizes the components of the Company’s total operating lease costs (in thousands):

	Three Months Ended   December 31, 2019
Operating Lease Expense	$	974
Variable Lease Expense (1)	134
Short-Term Lease Expense (2)	64
Sublease Income	(80		)
Total Lease Expense	$	1,092
Short-Term Lease Costs Recorded to Property, Plant and Equipment (3)	$	7,512

⁽¹⁾  Variable lease payments that are not dependent on an index or rate are not included in the lease liability.

⁽²⁾  Short-term lease costs exclude expenses related to leases with a lease term of one month or less.

⁽³⁾  Short-term lease costs relating to drilling rig leases that are capitalized as part of oil and natural gas properties under full cost pool accounting.

Right-of-use assets and lease liabilities are recognized at the commencement date of a leasing arrangement based on the present value of lease payments over the lease term. As of December 31, 2019, the weighted average remaining lease term was 8.7 years and the weighted average discount rate was 3.49%.

The Company’s right-of-use operating lease assets are reflected as Deferred Charges on the Consolidated Balance Sheet. The corresponding operating lease liabilities are reflected in Other Accruals and Current Liabilities (current) and Other Deferred Credits (noncurrent). Short-term leases that have a lease term of one year or less are not recorded on the Consolidated Balance Sheet.

The following amounts related to operating leases were recorded on the Company’s Consolidated Balance Sheet (in thousands):

	At December 31, 2019
Assets:
Deferred Charges	$	18,940
Liabilities:
Other Accruals and Current Liabilities	$	3,298
Other Deferred Credits	$	15,434

For the three months ended December 31, 2019, cash paid for operating liabilities, and reported in cash flows provided by operating activities on the Company’s Consolidated Statement of Cash Flows, was $1.1 million. During the three months ended December 31, 2019, the Company did not record any right-of-use assets in exchange for new lease liabilities.

18

The following schedule of operating lease liability maturities summarizes the undiscounted lease payments owed by the Company to lessors pursuant to contractual agreements in effect as of December 31, 2019 (in thousands):

	At December 31, 2019
2020 (remaining 9 months)	$	2,575
2021	2,813
2022	2,264
2023	2,270
2024	2,237
Thereafter	9,717
Total Lease Payments	21,876
Less: Interest	(3,144		)
Total Lease Liability	$	18,732

The future minimum operating lease payments as of September 30, 2019, as reported in the Company's 2019 Form 10-K, under the prior authoritative guidance are as follows (in thousands):

	At September 30, 2019
2020 (1)	$	12,356
2021	2,813
2022	2,264
2023	2,270
2024	2,237
Thereafter	9,717
Total Operating Lease Obligations	$	31,657

⁽¹⁾  The future minimum operating lease payment amount for 2020 includes short-term leases, including drilling rigs, that are not included in the schedule of operating lease liability maturities above under the new authoritative guidance.

Note 4 – Fair Value Measurements

The FASB authoritative guidance regarding fair value measurements establishes a fair-value hierarchy and prioritizes the inputs used in valuation techniques that measure fair value. Those inputs are prioritized into three levels. Level 1 inputs are unadjusted quoted prices in active markets for assets or liabilities that the Company can access at the measurement date. Level 2 inputs are inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly at the measurement date. Level 3 inputs are unobservable inputs for the asset or liability at the measurement date. The Company’s assessment of the significance of a particular input to the fair value measurement requires judgment, and may affect the valuation of fair value assets and liabilities and their placement within the fair value hierarchy levels.

19

The following table sets forth, by level within the fair value hierarchy, the Company's financial assets and liabilities (as applicable) that were accounted for at fair value on a recurring basis as of December 31, 2019 and September 30, 2019.  Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The fair value presentation for over the counter swaps combines gas and oil swaps because a significant number of the counterparties enter into both gas and oil swap agreements with the Company.

Derivative Financial Instruments

At December 31, 2019 and September 30, 2019, the derivative financial instruments reported in Level 1 consist of natural gas NYMEX and ICE futures contracts used by NFR (included in the All Other category). Hedging collateral deposits of $9.7 million (at December 31, 2019) and $6.8 million (at September 30, 2019), which were associated with these futures contracts, have been reported in Level 1 as well. The derivative financial instruments reported in Level 2 at December 31, 2019 and September 30, 2019 consist of natural gas price swap agreements used in the Company’s Exploration and Production segment and in its NFR operations, crude oil price swap agreements used in the Company’s Exploration and Production segment, basis hedge swap agreements used by NFR and foreign currency contracts used in the Company's Exploration and Production segment. The fair value of the Level 2 price swap agreements is based on an internal, discounted cash flow model that uses observable inputs (i.e. LIBOR based discount rates and basis differential information, if applicable, at active natural gas and crude oil trading markets). The fair value of the Level 2 foreign currency contracts is determined using the market approach based on observable market transactions of forward Canadian currency rates. 

The accounting rules for fair value measurements and disclosures require consideration of the impact of nonperformance risk (including credit risk) from a market participant perspective in the measurement of the fair value of assets and liabilities.  At December 31, 2019, the Company determined that nonperformance risk would have no material impact on its financial position or results of operation.  To assess nonperformance risk, the Company considered information such as any applicable collateral posted, master netting arrangements, and applied a market-based method by using the counterparty's (assuming the derivative is in a gain position) or the Company’s (assuming the derivative is in a loss position) credit default swaps rates.

For the quarters ended December 31, 2019 and December 31, 2018, there were no assets or liabilities measured at fair value and classified as Level 3. For the quarters ended December 31, 2019 and December 31, 2018, no transfers in or out of Level 1 or Level 2 occurred.

Note 5 – Financial Instruments

Long-Term Debt.  The fair market value of the Company’s debt, as presented in the table below, was determined using a discounted cash flow model, which incorporates the Company’s credit ratings and current market conditions in determining the yield, and subsequently, the fair market value of the debt.  Based on these criteria, the fair market value of long-term debt, including current portion, was as follows (in thousands): 

	December 31, 2019				September 30, 2019
	Carrying Amount		Fair Value		Carrying Amount		Fair Value
Long-Term Debt	$	2,134,339	$	2,253,232	$	2,133,718	$	2,257,085

The fair value amounts are not intended to reflect principal amounts that the Company will ultimately be required to pay. Carrying amounts for other financial instruments recorded on the Company’s Consolidated Balance Sheets approximate fair value. The fair value of long-term debt was calculated using observable inputs (U.S. Treasuries/LIBOR for the risk free component and company specific credit spread information – generally obtained from recent trade activity in the debt).  As such, the Company considers the debt to be Level 2.

Any temporary cash investments, notes payable to banks and commercial paper are stated at cost. Temporary cash investments are considered Level 1, while notes payable to banks and commercial paper are considered to be Level 2.  Given the short-term nature of the notes payable to banks and commercial paper, the Company believes cost is a reasonable approximation of fair value.

Other Investments. The components of the Company's Other Investments are as follows (in thousands):

	At December 31, 2019		At September 30, 2019
Life Insurance Contracts	$	41,336	$	41,074
Equity Mutual Fund	36,740		40,660
Fixed Income Mutual Fund	62,220		62,339
Marketable Equity Securities	933		844
	$	141,229	$	144,917

21

Investments in life insurance contracts are stated at their cash surrender values or net present value. Investments in an equity mutual fund, a fixed income mutual fund and the stock of an insurance company (marketable equity securities) are stated at fair value based on quoted market prices with changes in fair value recognized in net income. The insurance contracts and marketable equity and fixed income securities are primarily informal funding mechanisms for various benefit obligations the Company has to certain employees.

Derivative Financial Instruments.  The Company uses derivative financial instruments to manage commodity price risk in the Exploration and Production segment as well as by NFR (included in the All Other category). The Company enters into futures contracts and over-the-counter swap agreements for natural gas and crude oil to manage the price risk associated with forecasted sales of gas and oil. In addition, the Company also enters into foreign exchange forward contracts to manage the risk of currency fluctuations associated with transportation costs denominated in Canadian currency in the Exploration and Production segment. These instruments are accounted for as cash flow hedges. The Company also enters into futures contracts and swaps, which are accounted for as cash flow hedges, to manage the price risk associated with forecasted gas purchases. The Company enters into futures contracts and swaps to mitigate risk associated with fixed price sales commitments, fixed price purchase commitments, and the decline in value of natural gas held in storage. These instruments are accounted for as fair value hedges. The duration of the Company’s combined cash flow and fair value commodity hedges does not typically exceed 5 years while the foreign currency forward contracts do not exceed 7 years. The Exploration and Production segment holds the majority of the Company’s derivative financial instruments.

The Company has presented its net derivative assets and liabilities as “Fair Value of Derivative Financial Instruments” on its Consolidated Balance Sheets at December 31, 2019 and September 30, 2019.  Substantially all of the derivative financial instruments reported on those line items relate to commodity contracts and a small portion relates to foreign currency forward contracts.

Cash Flow Hedges

For derivative instruments that are designated and qualify as a cash flow hedge, the gain or loss on the derivative is reported as a component of other comprehensive income (loss) and reclassified into earnings in the period or periods during which the hedged transaction affects earnings. Prior to October 1, 2019, gains and losses on the derivative representing either hedge ineffectiveness or hedge components excluded from the the assessment of effectiveness were recognized in current earnings rather than as a component of other comprehensive income (loss). During the quarter ended December 31, 2018, the Company recorded a $6.5 million hedging ineffectiveness gain that impacted operating revenue. With the October 1, 2019 adoption of the authoritative guidance that changes the financial reporting of hedging relationships and simplifies the application of hedge accounting, derivative instruments that are designated and qualify as a cash flow hedge will no longer have hedge ineffectiveness or a component excluded from the assessment of the effectiveness.

As of December 31, 2019, the Company had the following commodity derivative contracts (swaps and futures contracts) outstanding:

Commodity	Units
Natural Gas	88.1	Bcf (short positions)
Natural Gas	2.7	Bcf (long positions)
Crude Oil	2,376,000	Bbls (short positions)

    

As of December 31, 2019, the Company was hedging a total of $77.3 million of forecasted transportation costs denominated in Canadian dollars with foreign currency forward contracts (long positions).

As of December 31, 2019, the Company had $41.8 million ($30.7 million after tax) of net hedging gains included in the accumulated other comprehensive income (loss) balance. It is expected that $39.1 million ($28.7 million after tax) of unrealized gains will be reclassified into the Consolidated Statement of Income within the next 12 months as the underlying hedged transactions are recorded in earnings.

Total	$	495		$	44,518			$	7,352		$	(20,517	)

Fair Value Hedges

The Company utilizes fair value hedges to mitigate risk associated with fixed price sales commitments, fixed price purchase commitments and the decline in the value of certain natural gas held in storage. With respect to fixed price sales commitments, the Company enters into long positions to mitigate the risk of price increases for natural gas supplies that could occur after the Company enters into fixed price sales agreements with its customers. With respect to fixed price purchase commitments, the Company enters into short positions to mitigate the risk of price decreases that could occur after the Company locks into fixed price purchase deals with its suppliers. With respect to storage hedges, the Company enters into short positions to mitigate the risk of price decreases that could result in a lower of cost or net realizable value writedown of the value of natural gas in storage that is recorded in the Company’s financial statements. As of December 31, 2019, NFR had fair value hedges covering approximately 23.5 Bcf (23.3 Bcf of fixed price sales commitments and 0.2 Bcf of commitments related to the withdrawal of storage gas). For derivative instruments that are designated and qualify as a fair value hedge, the gain or loss on the derivative as well as the offsetting gain or loss on the hedged item attributable to the hedged risk completely offset each other in current earnings, as shown below.

Credit Risk

The Company may be exposed to credit risk on any of the derivative financial instruments that are in a gain position. Credit risk relates to the risk of loss that the Company would incur as a result of nonperformance by counterparties pursuant to the terms of their contractual obligations. To mitigate such credit risk, management performs a credit check, and then on a quarterly basis monitors counterparty credit exposure. The majority of the Company’s counterparties are financial institutions and energy traders. The Company has over-the-counter swap positions and applicable foreign currency forward contracts with fourteen counterparties of which twelve are in a net gain position. On average, the Company had $3.4 million of credit exposure per counterparty in a gain position at December 31, 2019. The maximum credit exposure per counterparty in a gain position at

23

December 31, 2019 was $6.9 million. As of December 31, 2019, no collateral was received from the counterparties by the Company. The Company's gain position on such derivative financial instruments had not exceeded the established thresholds at which the counterparties would be required to post collateral, nor had the counterparties' credit ratings declined to levels at which the counterparties were required to post collateral.

As of December 31, 2019, eleven of the fourteen counterparties to the Company’s outstanding derivative instrument contracts (specifically the over-the-counter swaps and applicable foreign currency forward contracts) had a common credit-risk related contingency feature. In the event the Company’s credit rating increases or falls below a certain threshold (applicable debt ratings), the available credit extended to the Company would either increase or decrease. A decline in the Company’s credit rating, in and of itself, would not cause the Company to be required to increase the level of its hedging collateral deposits (in the form of cash deposits, letters of credit or treasury debt instruments). If the Company’s outstanding derivative instrument contracts were in a liability position (or if the liability were larger) and/or the Company’s credit rating declined, then additional hedging collateral deposits may be required.  At December 31, 2019, the fair market value of the derivative financial instrument assets with a credit-risk related contingency feature was $31.3 million according to the Company’s internal model (discussed in Note 4 — Fair Value Measurements).  At December 31, 2019, the fair market value of the derivative financial instrument liabilities with a credit-risk related contingency feature was $0.6 million according to the Company's internal model. For its over-the-counter swap agreements and foreign currency forward contracts, no hedging collateral deposits were required to be posted by the Company at December 31, 2019.

For its exchange traded futures contracts, the Company was required to post $9.7 million in hedging collateral deposits as of December 31, 2019. As these are exchange traded futures contracts, there are no specific credit-risk related contingency features. The Company posts or receives hedging collateral based on open positions and margin requirements it has with its counterparties.

The Company’s requirement to post hedging collateral deposits and the Company's right to receive hedging collateral deposits is based on the fair value determined by the Company’s counterparties, which may differ from the Company’s assessment of fair value. Hedging collateral deposits may also include closed derivative positions in which the broker has not cleared the cash from the account to offset the derivative liability. The Company records liabilities related to closed derivative positions in Other Accruals and Current Liabilities on the Consolidated Balance Sheet. These liabilities are relieved when the broker clears the cash from the hedging collateral deposit account.

Note 6 – Income Taxes

The effective tax rates for the quarters ended December 31, 2019 and December 31, 2018 were 26.6% and 18.2%, respectively. The increase in the effective tax rate was primarily the result of the reversal of a $5.0 million valuation allowance in fiscal 2019 related to sequestration of AMT credit refunds discussed below, differences between the book and tax treatment of stock compensation, as well as the elimination of the Enhanced Oil Recovery tax credit in fiscal 2020.

The 2017 Tax Reform Act repealed the corporate alternative minimum tax (AMT) and provides that the Company’s existing AMT credit carryovers are refundable, if not utilized to reduce tax, beginning in fiscal 2019. As of September 30, 2018, the Company had $85.0 million of AMT credit carryovers that are expected to be refunded between fiscal 2020 and fiscal 2023, if not previously utilized. During fiscal 2018, the Department of Treasury indicated that a portion of the refundable AMT credit carryovers would be subject to sequestration. Accordingly, the Company recorded a $5.0 million valuation allowance related to this sequestration in fiscal 2018. During the quarter ended December 31, 2018, the Office of Management and Budget determined that these AMT refunds would not be subject to sequestration. As such, the Company removed the valuation allowance. These amounts are recorded in Deferred Income Taxes and will be reclassified to a receivable when the amounts are expected to be realized in cash. The Company reclassified AMT credit refunds of $21.3 million and $42.1 million from Deferred Income Taxes to Other Assets at December 31, 2019 and 2018, respectively. The Company received $42.5 million of AMT credit refunds related to fiscal 2019 in January 2020.

The SEC issued guidance in Staff Accounting Bulletin 118 (SAB 118) which provides for up to a one year period (the measurement period) in which to complete the required analysis and income tax accounting for the 2017 Tax Reform Act. Based upon the available guidance, the Company completed the remeasurement of deferred income taxes as of December 31, 2018. Any subsequent guidance or clarification related to the 2017 Tax Reform Act will be accounted for in the period that the guidance is issued.

⁽¹⁾  Paid in Capital includes compensation costs associated with performance shares and/or restricted stock awards. The expense is included within Net Income Available For Common Stock, net of tax benefits.

Common Stock.  During the three months ended December 31, 2019, the Company issued 86,635 original issue shares of common stock for restricted stock units that vested and 231,246 original issue shares of common stock for performance shares that vested.  The Company also issued 9,480 original issue shares of common stock to the non-employee directors of the Company who receive compensation under the Company’s 2009 Non-Employee Director Equity Compensation Plan, as partial consideration for the directors’ services during the three months ended December 31, 2019.  Holders of stock-based compensation awards will often tender shares of common stock to the Company for payment of applicable withholding taxes.  During the three months ended December 31, 2019, 91,120 shares of common stock were tendered to the Company for such purposes.  The Company considers all shares tendered as cancelled shares restored to the status of authorized but unissued shares, in accordance with New Jersey law.

Current Portion of Long-Term Debt.  None of the Company's long-term debt as of December 31, 2019 and September 30, 2019 had a maturity date within the following twelve-month period.

Note 8 – Commitments and Contingencies

Environmental Matters.  The Company is subject to various federal, state and local laws and regulations relating to the protection of the environment.  The Company has established procedures for the ongoing evaluation of its operations to identify potential environmental exposures and to comply with regulatory requirements.  It is the Company’s policy to accrue estimated environmental clean-up costs (investigation and remediation) when such amounts can reasonably be estimated and it is probable that the Company will be required to incur such costs. 

At December 31, 2019, the Company has estimated its remaining clean-up costs related to former manufactured gas plant sites will be approximately $6.9 million, which includes a $3.7 million estimated minimum liability to remediate a former

25

manufactured gas plant site located in New York.  In March 2018, the NYDEC issued a Record of Decision for this New York site and the minimum liability reflects the remedy selected in the Record of Decision. The Company's liability for such clean-up costs has been recorded in Other Deferred Credits on the Consolidated Balance Sheet at December 31, 2019. The Company expects to recover its environmental clean-up costs through rate recovery over a period of approximately 3 years and is currently not aware of any material additional exposure to environmental liabilities.  However, changes in environmental laws and regulations, new information or other factors could have an adverse financial impact on the Company.

Northern Access Project. On February 3, 2017, Supply Corporation and Empire received FERC approval of the Northern Access project described herein. Shortly thereafter, the NYDEC issued a Notice of Denial of the federal Clean Water Act Section 401 Water Quality Certification and other state stream and wetland permits for the New York portion of the project (the Water Quality Certification for the Pennsylvania portion of the project was received in January of 2017). The United States Court of Appeals for the Second Circuit (the “Second Circuit Court of Appeals”) held in the Company’s favor in its appeal of this decision, vacating the NYDEC denial and remanding to the NYDEC. The NYDEC subsequently issued a second denial, which the Company has appealed to the Second Circuit Court of Appeals. The court has held this appeal in abeyance pending the outcome of the FERC waiver appeal, described below. While the Company’s initial appeal was pending before the Second Circuit Court of Appeals, the FERC issued an Order finding that the NYDEC exceeded the statutory time frame to take action under the Clean Water Act and, therefore, waived its opportunity to approve or deny the Water Quality Certification. FERC denied rehearing requests associated with its Order and FERC's decisions have been appealed and are pending in a separate action before the Second Circuit Court of Appeals. In addition, the Company commenced legal action in New York State Supreme Court challenging the NYDEC's actions with regard to various state permits. The Company remains committed to the project. In light of these pending legal actions and the need to complete necessary project development activities in advance of construction, the in-service date for the project is expected to be no earlier than fiscal 2022.

Other.  The Company is involved in other litigation and regulatory matters arising in the normal course of business.  These other matters may include, for example, negligence claims and tax, regulatory or other governmental audits, inspections, investigations and other proceedings.  These matters may involve state and federal taxes, safety, compliance with regulations, rate base, cost of service and purchased gas cost issues, among other things.  While these other matters arising in the normal course of business could have a material effect on earnings and cash flows in the period in which they are resolved, an estimate of the possible loss or range of loss, if any, cannot be made at this time.

Note 9 – Business Segment Information    

The Company reports financial results for four segments: Exploration and Production, Pipeline and Storage, Gathering and Utility.  The division of the Company’s operations into reportable segments is based upon a combination of factors including differences in products and services, regulatory environment and geographic factors. As reported in the Company's 2019 Form 10-K, the Company previously reported financial results for five business segments: Exploration and Production, Pipeline and Storage, Gathering, Utility and Energy Marketing. However, management made the decision to eliminate the Energy Marketing segment as a reportable segment based on the fact that the energy marketing operations do not meet any of the quantitative thresholds specified by authoritative guidance related to segment reporting. Furthermore, from a qualitative standpoint, management’s focus has changed regarding the energy marketing operations, and management no longer considers the energy marketing operations to be integral to the overall operations of the Company. As a result of this change in focus and the fact that the energy marketing operations cannot be aggregated into one of the other four reportable business segments, the energy marketing operations have been included in the All Other category in the disclosures that follow. Prior year segment information shown below has been restated to reflect this change in presentation.

The data presented in the tables below reflect financial information for the segments and reconciliations to consolidated amounts.  As stated in the 2019 Form 10-K, the Company evaluates segment performance based on income before discontinued operations (when applicable).  When this is not applicable, the Company evaluates performance based on net income.  There have not been any changes in the basis of segmentation nor in the basis of measuring segment profit or loss from those used in the Company’s 2019 Form 10-K.  A listing of segment assets at December 31, 2019 and September 30, 2019 is shown in the tables below.

Employer Contributions.    During the three months ended December 31, 2019, the Company contributed $7.8 million to its tax-qualified, noncontributory defined-benefit retirement plan (Retirement Plan) and $0.7 million to its VEBA trusts for its other post-retirement benefits.  In the remainder of 2020, the Company expects its contributions to the Retirement Plan to be in the range of $17.0 million to $22.0 million. In the remainder of 2020, the Company expects its contributions to its VEBA trusts to be in the range of $2.0 million to $2.5 million.

Note 11 – Regulatory Matters

New York Jurisdiction

Distribution Corporation's current delivery rates in its New York jurisdiction were approved by the NYPSC in an order issued on April 20, 2017 with rates becoming effective May 1, 2017. The order provided for a return on equity of 8.7%. The order also directed the implementation of an earnings sharing mechanism to be in place beginning on April 1, 2018.

Pennsylvania Jurisdiction

Distribution Corporation’s Pennsylvania jurisdiction delivery rates are being charged to customers in accordance with a rate settlement approved by the PaPUC. The rate settlement does not specify any requirement to file a future rate case.

FERC Jurisdiction

Supply Corporation filed a Section 4 rate case on July 31, 2019 proposing rate increases to be effective September 1, 2019. The proposed rates reflect an annual cost of service of $295.4 million, a rate base of $970.8 million and a proposed cost of equity of 15%. The FERC has accepted the filed rates and suspended the effective date of the increases until February 1, 2020, when the rates will be made effective, subject to refund. If the rates finally approved at the end of the proceeding exceed the rates that were in effect at July 31, 2019, but are less than rates put into effect subject to refund on February 1, 2020, Supply Corporation would be required to refund the difference between the rates collected subject to refund and the final approved rates, with interest at the FERC-approved rate. If the rates approved at the end of the proceeding are lower than the rates in effect at July 31, 2019, such lower rates will become effective prospectively from the date of the applicable FERC order, and refunds with interest will be limited to the difference between the rates collected subject to refund and the rates in effect at July 31, 2019.

Empire's 2019 rate settlement requires a Section 4 rate case filing no later than May 1, 2025. Empire has no rate case currently on file.

Item 2.  Management's Discussion and Analysis of Financial Condition and Results of Operations

OVERVIEW

Please note that this overview is a high-level summary of items that are discussed in greater detail in subsequent sections of this report.

The Company is a diversified energy company engaged principally in the production, gathering, transportation, distribution and marketing of natural gas. The Company operates an integrated business, with assets centered in western New York and Pennsylvania, being utilized for, and benefiting from, the production and transportation of natural gas from the Appalachian basin. Current development activities are focused primarily in the Marcellus and Utica Shale. The common geographic footprint of the Company’s subsidiaries enables them to share management, labor, facilities and support services across various businesses and pursue coordinated projects designed to produce and transport natural gas from the Appalachian basin to markets in Canada and the eastern United States. The Company's efforts in this regard are not limited to affiliated projects. The Company has also been designing and building pipeline projects for the transportation of natural gas for non-affiliated natural gas producers in the Appalachian basin. The Company also develops and produces oil reserves, primarily in California. The Company reports financial results for four business segments. For a discussion of the Company's earnings, refer to the Results of Operations section below.

The Company continues to pursue development projects to expand its Pipeline and Storage segment. One project on Empire’s system, referred to as the Empire North Project, would allow for the transportation of 205,000 Dth per day of additional shale supplies from interconnections in Tioga County, Pennsylvania, to TransCanada Pipeline, and the TGP 200 Line. Project construction is under way. The Empire North Project has a projected in-service date in the fourth quarter of fiscal 2020 and an estimated cost of approximately $145 million. Another project on Supply Corporation’s system, referred to as the FM100 Project, will upgrade a 1950’s era pipeline in northwestern Pennsylvania and create approximately 330,000 Dth per day of additional transportation capacity on Supply Corporation’s system in Pennsylvania from a receipt point with NFG Midstream Clermont, LLC in McKean County, Pennsylvania to the Transcontinental Gas Pipe Line Company, LLC system at Leidy, Pennsylvania. The FM100 Project has a target in-service date in late calendar 2021 and a preliminary cost estimate of approximately $280 million. These and other projects are discussed in more detail in the Capital Resources and Liquidity section that follows.

On February 3, 2017, the Company, in its Pipeline and Storage segment, received FERC approval of a project to move significant prospective Marcellus production from Seneca’s Western Development Area at Clermont to an Empire interconnection with TransCanada Pipeline at Chippawa and an interconnection with Tennessee Gas Pipeline’s 200 Line in East Aurora, New York (“Northern Access project”). In light of numerous legal actions and the need to complete necessary project development activities in advance of construction, the in-service date for the project is expected to be no earlier than fiscal 2022. For further discussion of the Northern Access project, refer to Item 1 at Note 8 — Commitments and Contingencies.

Given the current low commodity price environment, the Company's Exploration and Production segment moved from a 3-rig development program to a 2-rig development program in the Appalachian region in January 2020, and intends to move to a single-rig development program during the second half of fiscal 2020. While this will result in lower capital spending in this segment (expected to be in the range of $375 million to $410 million for fiscal 2020), Seneca still anticipates an increase in natural gas production when comparing fiscal 2020 to fiscal 2019.

As discussed in the following Critical Accounting Estimates section, the Company uses the full cost method of accounting for determining the book value of its oil and natural gas properties in the Exploration and Production segment and that book value is subject to a quarterly ceiling test. While the Company did not record an impairment under the ceiling test during the quarter ended December 31, 2019, it is anticipated that the current low commodity price environment will lead to impairments during the remaining quarters of fiscal 2020.

From a rate perspective, Supply Corporation filed a Section 4 rate case on July 31, 2019. The new rates are scheduled to become effective on February 1, 2020, subject to refund, if the case is not settled before then. For further discussion of Supply Corporation's rate matters, refer to the Rate and Regulatory Matters section below.

From a legislation perspective, in July 2019, New York State enacted legislation known as the Climate Leadership & Community Protection Act (CLCPA). This climate legislation mandates reducing greenhouse gas emissions to 60% of 1990 levels by 2030, and to 15% of 1990 levels by 2050, with the remaining emission reduction achieved by controlled offsets. The legislation also requires electric generators to meet 70% of demand with renewable energy by 2030 and 100% by 2040. In the near-term,

29

the CLCPA establishes a climate action council and a series of advisory panels and working groups to study how the state will achieve the aggressive emission reduction targets.

From a financing perspective, the Company expects to use cash on hand, cash from operations and short-term debt to meet its capital expenditure needs for fiscal 2020 and may issue long-term debt during fiscal 2020 as needed.

CRITICAL ACCOUNTING ESTIMATES

For a complete discussion of critical accounting estimates, refer to "Critical Accounting Estimates" in Item 7 of the Company's 2019 Form 10-K.  There have been no material changes to that disclosure other than as set forth below.  The information presented below updates and should be read in conjunction with the critical accounting estimates in that Form 10-K.

Oil and Gas Exploration and Development Costs.  The Company, in its Exploration and Production segment, follows the full cost method of accounting for determining the book value of its oil and natural gas properties.  In accordance with this methodology, the Company is required to perform a quarterly ceiling test.  Under the ceiling test, the present value of future revenues from the Company's oil and gas reserves based on an unweighted arithmetic average of the first day of the month oil and gas prices for each month within the twelve-month period prior to the end of the reporting period (the “ceiling”) is compared with the book value of the Company’s oil and gas properties at the balance sheet date.  If the book value of the oil and gas properties exceeds the ceiling, a non-cash impairment charge must be recorded to reduce the book value of the oil and gas properties to the calculated ceiling.  At December 31, 2019, the ceiling exceeded the book value of the oil and gas properties by approximately $59.1 million. The 12-month average of the first day of the month price for crude oil for each month during the twelve months ended December 31, 2019, based on posted Midway Sunset prices, was $59.50 per Bbl.  The 12-month average of the first day of the month price for natural gas for each month during the twelve months ended December 31, 2019, based on the quoted Henry Hub spot price for natural gas, was $2.58 per MMBtu.  (Note – because actual pricing of the Company’s various producing properties varies depending on their location and hedging, the prices used to calculate the ceiling may differ from the Midway Sunset and Henry Hub prices, which are only indicative of the 12-month average prices for the twelve months ended December 31, 2019. Pricing differences would include adjustments for regional market differentials, transportation fees and contractual arrangements.) The following table illustrates the sensitivity of the ceiling test calculation to commodity price changes, specifically showing the amount the ceiling would have exceeded the book value of the Company's oil and gas properties at December 31, 2019 if crude oil prices were $5 per Bbl lower than the average prices used at December 31, 2019, as well as showing the impairment that the Company would have recorded at December 31, 2019 if natural gas prices were $0.25 per MMBtu lower than the average prices used at December 31, 2019, and the impairment that the Company would have recorded at December 31, 2019 if both natural gas prices and crude oil prices were $0.25 per MMBtu and $5 per Bbl lower than the average prices used at December 31, 2019 (all amounts are presented after-tax). These calculated amounts are based solely on price changes and do not take into account any other changes to the ceiling test calculation, including, among others, changes in reserve quantities and future cost estimates. Looking ahead, the first day of the month Henry Hub spot price for natural gas in January 2020 was $2.05 per MMBtu. Given these January prices, the potential that prices could stay at this level in future months, and the expected loss of higher gas and oil prices from the 12-month average that will be used in the ceiling test at March 31, 2020, June 30, 2020 and September 30, 2020, the Company expects to experience ceiling test impairments in each of these quarters.   

Ceiling Testing Sensitivity to Commodity Price Changes
(Millions)	$0.25/MMBtu Decrease in Natural Gas Prices		$5.00/Bbl Decrease in Crude Oil Prices		$0.25/MMBtu Decrease in Natural Gas Prices and $5.00/Bbl Decrease in Crude Oil Prices

RESULTS OF OPERATIONS

Earnings

The Company's earnings were $86.6 million for the quarter ended December 31, 2019 compared to earnings of $102.7 million for the quarter ended December 31, 2018.  The decrease in earnings of $16.1 million is primarily a result of lower earnings in the Exploration and Production segment and Pipeline and Storage segment. Higher earnings in the Gathering segment, Utility segment and Corporate and All Other categories partially offset these decreases.

2019 Compared with 2018

Operating revenues for the Exploration and Production segment increased $3.1 million for the quarter ended December 31, 2019 as compared with the quarter ended December 31, 2018. Gas revenues after hedging increased $7.5 million due to a 9.0 Bcf increase in gas production, which was largely offset by the impact of a $0.29 per Mcf decrease in the weighted average price of gas after hedging. The increase in gas production was largely due to new Marcellus and Utica wells completed and connected to sales in the Western and Eastern Development Areas in the Appalachian region during the quarter ended December 31, 2019 as compared with the quarter ended December 31, 2018. Oil revenues after hedging increased $2.6 million due to a 29 Mbbl increase in crude oil production coupled with the impact of a $1.22 per Bbl increase in the weighted average price of oil after hedging. The increase in oil production revenue was largely due to higher production in the West Coast region. These increases to operating revenues were partially offset by a $6.7 million decrease in other revenue primarily due to mark-to-market adjustments related to hedging ineffectiveness that were recorded during the quarter ended December 31, 2018 that did not recur during the quarter ended December 31, 2019.

The Exploration and Production segment's earnings for the quarter ended December 31, 2019 were $24.0 million, a decrease of $14.2 million when compared with earnings of $38.2 million for the quarter ended December 31, 2018.  The decrease in earnings was due to lower natural gas prices after hedging ($12.6 million), higher depletion expense ($7.5 million), higher production expenses ($6.5 million), higher other operating expenses ($0.6 million), higher interest expense ($0.7 million), a higher effective income tax rate ($1.3 million), the impact of the aforementioned prior year quarter mark-to-market adjustments related to hedging ineffectiveness ($5.1 million) and the impact of a remeasurement of the segment's accumulated deferred income taxes in the prior year quarter that did not recur in fiscal 2020 ($1.0 million). The increase in depletion expense was primarily due to the increase in production coupled with a $0.06 per Mcfe increase in the depletion rate, which was driven by an increase in capitalized costs in Seneca’s full cost pool. The increase in production expenses was primarily due to increased gathering and transportation costs in the Appalachian region. The increase in other operating expenses was largely due to an increase in purchased emissions credits in the West Coast region. The increase in interest expense was largely due to increased intercompany borrowings. The increase in the effective income tax rate was primarily due to the impact of the Enhanced Oil Recovery tax credit that was applicable in the quarter ended December 31, 2018 but was not available in the quarter ended December 31, 2019. These factors, which decreased earnings during the quarter ended December 31, 2019, were partially offset by the positive impacts of higher natural gas production ($18.5 million), higher crude oil production ($1.5 million), higher crude oil prices after hedging ($0.6 million) and lower other taxes ($1.3 million). The decrease in other taxes was primarily due to a lower Pennsylvania impact fee accrual for the quarter ended December 31, 2019 as a result of lower NYMEX natural gas prices.

2019 Compared with 2018

Operating revenues for the Pipeline and Storage segment decreased $4.8 million for the quarter ended December 31, 2019 as compared with the quarter ended December 31, 2018.  The decrease in operating revenues was primarily due to a decrease in transportation revenues of $2.7 million and a decrease in other revenues of $1.7 million. The decrease in transportation revenues was primarily attributable to an Empire system transportation contract termination in December 2018. Partially offsetting this decrease was an increase in transportation revenues due to an increase in Empire's rates effective January 1, 2019 in accordance with Empire's rate case settlement, which was approved by the FERC on May 3, 2019, combined with an increase in demand charges for transportation service from Supply Corporation's Line N to Monaca project, which was placed in service on November 1, 2019. The decrease in other revenues was due to proceeds received by Supply Corporation in the first quarter of fiscal 2019 related to a contract termination as a result of a shipper's bankruptcy that did not recur in the first quarter of fiscal 2020.

Transportation volume for the quarter ended December 31, 2019 increased by 16.5 Bcf from the prior year's quarter. The increase in transportation volume for the quarter primarily reflects an increase in capacity utilization by certain contract shippers. Volume fluctuations, other than those caused by the addition or termination of contracts, generally do not have a significant impact on revenues as a result of the straight fixed-variable rate design utilized by Supply Corporation and Empire.

The Pipeline and Storage segment’s earnings for the quarter ended December 31, 2019 were $18.1 million, a decrease of $7.0 million when compared with earnings of $25.1 million for the quarter ended December 31, 2018.  The decrease in earnings was primarily due to the earnings impact of lower operating revenues of $3.8 million, as discussed above, combined with higher income tax expense ($2.5 million) and higher property taxes ($0.8 million). The increase in income tax expense is primarily due to permanent differences related to stock compensation activity. The increase in property taxes was due to an increase in scheduled payments in lieu of taxes in accordance with agreements in place, as well as higher town, county and school taxes due to an increase in assessed values from new projects placed in service. These earnings decreases were slightly offset by a decrease in operating expenses ($0.6 million) primarily due to a decrease in personnel and compensation costs as well as costs associated with maintenance of compressor stations, partially offset by an increase in pipeline integrity program expenses.

	2019	2018	Increase (Decrease)
Gathered Volume - (MMcf)	64,392	54,688	9,704

2019 Compared with 2018

Operating revenues for the Gathering segment increased $5.1 million for the quarter ended December 31, 2019 as compared with the quarter ended December 31, 2018. The increase was primarily due to a 9.7 Bcf net increase in gathered volume resulting from a 4.0 Bcf, 3.8 Bcf and 3.5 Bcf increase in volume on Midstream Company's Trout Run, Wellsboro and Clermont gathering systems, respectively, offset by a 1.6 Bcf decline on the Covington gathering system. The net increase in gathered volume can be attributed to the increase in Seneca's gross natural gas production in the Appalachian region.

The Gathering segment’s earnings for the quarter ended December 31, 2019 were $15.9 million, an increase of $1.7 million when compared with earnings of $14.2 million for the quarter ended December 31, 2018.  The increase in earnings was mainly due to the impact of higher gathering revenues discussed above ($4.0 million), which was partially offset by higher operating expenses ($1.3 million), higher depreciation expense ($0.4 million), and the impact of a nonrecurring income tax benefit recorded in the prior year quarter to adjust the remeasurement of deferred income taxes resulting from the 2017 Tax Reform Act ($0.5 million). The increase in operating expenses was due largely to increased preventative maintenance and overhaul activities at Covington and Trout Run compressor stations during the quarter ended December 31, 2019. The increase in depreciation expense was due to an increase in the average gross property, plant and equipment assets in service as compared to the prior year.

2019 Compared with 2018

Operating revenues for the Utility segment decreased $25.8 million for the quarter ended December 31, 2019 as compared with the quarter ended December 31, 2018.  The decrease primarily resulted from a $23.0 million decrease in retail gas sales revenue, a $2.3 million decrease in transportation revenues and a $0.5 million decrease in other revenues. The decrease in retail gas sales revenue was largely due to a decrease in the cost of gas sold (per Mcf) coupled with slightly lower throughput due to warmer weather. The decline in transportation revenues was primarily due a 1.7 Bcf decrease in transportation throughput due to warmer weather and the migration of residential transportation customers to retail. The decrease in other revenues was largely due to the impact of regulatory adjustments, including an earnings sharing accrual recorded in fiscal 2020 for $0.5 million in the segment's New York service territory.

The Utility segment’s earnings for the quarter ended December 31, 2019 were $26.6 million, an increase of $1.0 million when compared with earnings of $25.6 million for the quarter ended December 31, 2018. The increase in earnings was largely attributable to the impact of regulatory adjustments ($0.9 million) and the positive earnings impact related to a system modernization tracker ($0.3 million). These increases were slightly offset by higher income tax expense ($0.8 million). The increase in income tax expense was primarily due to permanent differences related to stock compensation activity.

Corporate and All Other

2019 Compared with 2018

Corporate and All Other operations had earnings of $2.0 million for the quarter ended December 31, 2019, an increase of $2.5 million when compared with a loss of $0.5 million for the quarter ended December 31, 2018. The increase in earnings was primarily attributable to lower unrealized losses on investments in equity securities recorded during the quarter ended December 31, 2019 ($4.2 million) coupled with higher other income ($1.5 million) that was driven largely by an increase in realized gains on investments in equity securities sold in the current quarter. These positive drivers of earnings were partially offset by the impact of the prior year remeasurement of deferred income taxes under the 2017 Tax Reform Act that lowered income tax expense for the quarter ended December 31, 2018 ($3.5 million).

Interest Expense on Long-Term Debt

Interest on long-term debt was relatively flat for the quarter ended December 31, 2019 as compared with the quarter ended December 31, 2018. No new additional debt was issued or repaid during the quarters ended December 31, 2019 and

35

December 31, 2018. In addition, amortization of debt premiums discount and expense and capitalized interest remained comparable year over year.

CAPITAL RESOURCES AND LIQUIDITY

The Company’s primary sources of cash during the three-month period ended December 31, 2019 consisted of cash provided by operating activities and net proceeds from short-term borrowings. The Company's primary source of cash during the three-month period ended December 31, 2018 consisted of cash provided by operating activities.

Operating Cash Flow

Internally generated cash from operating activities consists of net income available for common stock, adjusted for non-cash expenses, non-cash income and changes in operating assets and liabilities. Non-cash items include depreciation, depletion and amortization, deferred income taxes and stock-based compensation.

Cash provided by operating activities in the Utility and Pipeline and Storage segments may vary substantially from period to period because of the impact of rate cases. In the Utility segment, supplier refunds, over- or under-recovered purchased gas costs and weather may also significantly impact cash flow. The impact of weather on cash flow is tempered in the Utility segment’s New York rate jurisdiction by its WNC and in the Pipeline and Storage segment by the straight fixed-variable rate design used by Supply Corporation and Empire.

Because of the seasonal nature of the heating business in the Utility segment and in the Company's NFR operations (included in the All Other category), revenues in these businesses are relatively high during the heating season, primarily the first and second quarters of the fiscal year, and receivable balances historically increase during these periods from the receivable balances at September 30.

The storage gas inventory normally declines during the first and second quarters of the fiscal year and is replenished during the third and fourth quarters.  For storage gas inventory accounted for under the LIFO method, the current cost of replacing gas withdrawn from storage is recorded in the Consolidated Statements of Income and a reserve for gas replacement is recorded in the Consolidated Balance Sheets under the caption "Other Accruals and Current Liabilities." Such reserve is reduced as the inventory is replenished.

Cash provided by operating activities in the Exploration and Production segment may vary from period to period as a result of changes in the commodity prices of natural gas and crude oil as well as changes in production.  The Company uses various derivative financial instruments, including price swap agreements and futures contracts in an attempt to manage this energy commodity price risk.

Net cash provided by operating activities totaled $167.7 million for the three months ended December 31, 2019, an increase of $63.3 million compared with $104.4 million provided by operating activities for the three months ended December 31, 2018. The increase in cash provided by operating activities primarily reflects higher cash provided by operating activities in the Utility and Exploration and Production segments. The increase in the Utility segment is primarily due to the timing of gas cost recovery and the timing of receivable collections. The increase in the Exploration and Production segment is primarily due to higher cash receipts from natural gas production. The increase in cash provided by operating activities also reflects a decrease in contributions made to the Retirement Plan, primarily in the Utility and Pipeline and Storage segments.

(1) At December 31, 2019, capital expenditures for the Exploration and Production segment, the Pipeline and Storage segment, the Gathering segment and the Utility segment include $62.3 million, $22.7 million, $5.3 million and $3.5 million, respectively, of non-cash capital expenditures. At September 30, 2019, capital expenditures for the Exploration and Production segment, the Pipeline and Storage segment, the Gathering segment and the Utility segment included $38.0 million, $23.8 million, $6.6 million and $12.7 million, respectively, of non-cash capital expenditures. 

(2) At December 31, 2018, capital expenditures for the Exploration and Production segment, the Pipeline and Storage segment, the Gathering segment and the Utility segment included $66.1 million, $12.9 million, $4.4 million and $2.8 million, respectively, of non-cash capital expenditures.  At September 30, 2018, capital expenditures for the Exploration and Production segment, the Pipeline and Storage segment, the Gathering segment and the Utility segment included $51.3 million, $21.9 million, $6.1 million and $9.5 million, respectively, of non-cash capital expenditures.  

Exploration and Production 

The Exploration and Production segment capital expenditures for the three months ended December 31, 2019 were primarily well drilling and completion expenditures and included approximately $119.0 million for the Appalachian region (including $53.7 million in the Marcellus Shale area and $63.8 million in the Utica Shale area) and $7.9 million for the West Coast region.  These amounts included approximately $86.2 million spent to develop proved undeveloped reserves. 

The Exploration and Production segment capital expenditures for the three months ended December 31, 2018 were primarily well drilling and completion expenditures and included approximately $114.7 million for the Appalachian region (including $36.5 million in the Marcellus Shale area and $75.5 million in the Utica Shale area) and $5.5 million for the West Coast region.  These amounts included approximately $61.1 million spent to develop proved undeveloped reserves. 

Pipeline and Storage

The Pipeline and Storage segment capital expenditures for the three months ended December 31, 2019 were primarily for expenditures related to Empire's Empire North Project ($29.1 million) and Supply Corporation's Line N to Monaca Project ($3.3 million), as discussed below. In addition, the Pipeline and Storage segment capital expenditures for the three months ended December 31, 2019 include additions, improvements and replacements to this segment’s transmission and gas storage systems. The Pipeline and Storage capital expenditures for the three months ended December 31, 2018 were primarily for additions, improvements and replacements to this segment’s transmission and gas storage systems. In addition, the Pipeline and Storage segment capital expenditures for the three months ended December 31, 2018 include expenditures related to Supply Corporation's Line N to Monaca Project ($1.1 million).

In light of the continuing demand for pipeline capacity to move natural gas from new wells being drilled in Appalachia — specifically in the Marcellus and Utica Shale producing areas — Supply Corporation and Empire have completed and continue to pursue several expansion projects designed to move anticipated Marcellus and Utica production gas to other interstate pipelines

37

and to on-system markets, and markets beyond the Supply Corporation and Empire pipeline systems. Preliminary survey and investigation costs for expansion, routine replacement or modernization projects are initially recorded as Deferred Charges on the Consolidated Balance Sheet. Management may reserve for preliminary survey and investigation costs associated with large projects by reducing the Deferred Charges balance and increasing Operation and Maintenance Expense on the Consolidated Statement of Income. If it is determined that it is highly probable that a project for which a reserve has been established will be built, the reserve is reversed. This reversal reduces Operation and Maintenance Expense and reestablishes the original balance in Deferred Charges. The amounts remain in Deferred Charges until such time as capital expenditures for the project have been incurred and activities that are necessary to get the construction project ready for its intended use are in progress. At that point, the balance is transferred from Deferred Charges to Construction Work in Progress, a component of Property, Plant and Equipment on the Consolidated Balance Sheet.   

Supply Corporation completed a project to provide incremental natural gas transportation services from Line N to the ethane cracker facility being constructed by Shell Chemical Appalachia, LLC in Potter Township, Pennsylvania ("Line N to Monaca Project"), with transportation service beginning on November 1, 2019.  This project involved construction of a 4.5 mile pipeline extension from Line N to the facility and has resulted in Supply Corporation securing incremental firm transportation capacity commitments totaling 133,000 Dth per day on Line N and on the pipeline extension to the facility.  Supply Corporation was authorized to pursue the project by FERC under its blanket certificate as of May 30, 2018. As of December 31, 2019, approximately $22.1 million has been spent on the Line N to Monaca Project, all of which is included in Property, Plant and Equipment on the Consolidated Balance Sheet at December 31, 2019.

Empire concluded an Open Season on November 18, 2015, and has designed a project that would allow for the transportation of 205,000 Dth per day of additional shale supplies from interconnections in Tioga County, Pennsylvania, to TransCanada Pipeline, and the TGP 200 Line (“Empire North Project”). This project is fully subscribed under long term agreements and received the FERC Section 7(c) certificate on March 7, 2019. Project construction is under way. The Empire North Project has a projected in-service date in the fourth quarter of fiscal 2020 and an estimated capital cost of approximately $145 million.  As of December 31, 2019, approximately $74.5 million has been capitalized as Construction Work in Progress for this project, including $19.9 million of costs transferred from the Northern Access Project, which is discussed below.

Supply Corporation has developed its FM100 Project, which will upgrade a 1950's era pipeline in northwestern Pennsylvania and create approximately 330,000 Dth per day of additional transportation capacity in Pennsylvania from a receipt point with NFG Midstream Clermont, LLC in McKean County to the Transcontinental Gas Pipe Line Company, LLC (“Transco”) system at Leidy, Pennsylvania. A precedent agreement has been executed by Supply Corporation and Transco whereby this additional capacity is expected to be leased by Transco and become part of a Transco expansion project ("Leidy South") that will create incremental transportation capacity to Transco Zone 6 markets. Seneca is the anchor shipper on Leidy South, providing Seneca with an outlet to premium markets for its Marcellus and Utica production from both the Clermont-Rich Valley and Trout Run-Gamble areas. Supply Corporation filed a Section 7(c) application with the FERC in July 2019. The FM100 Project has a target in-service date in late calendar 2021 and a preliminary cost estimate of approximately $280 million. As of December 31, 2019, approximately $5.0 million has been spent to study this project, all of which has been included in Deferred Charges on the Consolidated Balance Sheet at December 31, 2019.

Supply Corporation and Empire have developed a project which would move significant prospective Marcellus production from Seneca's Western Development Area at Clermont to an Empire interconnection with TransCanada Pipeline at Chippawa and an interconnection with TGP's 200 Line in East Aurora, New York (the “Northern Access project”). The Northern Access project would provide an outlet to Dawn-indexed markets in Canada and to the TGP line serving the U.S. Northeast. The Northern Access project involves the construction of approximately 99 miles of largely 24” pipeline and approximately 27,500 horsepower of compression on the two systems. Supply Corporation, Empire and Seneca executed anchor shipper agreements for 350,000 Dth per day of firm transportation delivery capacity to Chippawa and 140,000 Dth per day of firm transportation capacity to a new interconnection with TGP's 200 Line on this project. On February 3, 2017, the Company received FERC approval of the project. Shortly thereafter, the NYDEC issued a Notice of Denial of the federal Clean Water Act Section 401 Water Quality Certification and other state stream and wetland permits for the New York portion of the project (the Water Quality Certification for the Pennsylvania portion of the project was received in January of 2017). The United States Court of Appeals for the Second Circuit (the “Second Circuit Court of Appeals”) held in the Company’s favor in its appeal of this decision, vacating the NYDEC denial and remanding to the NYDEC. The NYDEC subsequently issued a second denial, which the Company has appealed to the Second Circuit Court of Appeals. The court has held this appeal in abeyance pending the outcome of the FERC waiver appeal, described below. While the Company’s initial appeal was pending before the Second Circuit Court of Appeals, the FERC issued an Order finding that the NYDEC exceeded the statutory time frame to take action under the Clean Water Act and, therefore, waived its opportunity to approve or deny the Water Quality Certification. FERC denied rehearing requests associated with its Order, and FERC's decisions have been appealed and are pending in a separate action before the Second Circuit Court of Appeals. In addition, the Company commenced legal action in New York State Supreme Court challenging the NYDEC's actions with regard to various

38

state permits. The Company remains committed to the project. In light of these pending legal actions and the need to complete necessary project development activities in advance of construction, the in-service date for the project is expected to be no earlier than fiscal 2022. The Company will update the $500 million preliminary cost estimate when there is further clarity on that date. As of December 31, 2019, approximately $57.8 million has been spent on the Northern Access project, including $23.3 million that has been spent to study the project, for which no reserve has been established. The remaining $34.5 million spent on the project has been capitalized as Construction Work in Progress.

Gathering

The majority of the Gathering segment capital expenditures for the three months ended December 31, 2019 were for the continued expansion of Midstream Company’s Trout Run gathering system, Midstream Company's Clermont gathering system and Midstream Company's Wellsboro gathering system, as discussed below. Midstream Company spent $5.5 million, $3.2 million and $1.1 million, respectively, during the three months ended December 31, 2019 on the development of the Trout Run, Clermont and Wellsboro gathering systems. These expenditures were largely attributable to new gathering pipelines and the continued development of centralized station facilities, including increased compression horsepower at the Trout Run gathering system.

The majority of the Gathering segment capital expenditures for the three months ended December 31, 2018 were for the continued expansion of the Trout Run gathering system, Clermont gathering system and Wellsboro gathering system. Midstream Company spent $1.3 million, $3.0 million and $4.0 million, respectively, during the three months ended December 31, 2018 on the development of the Trout Run, Clermont and Wellsboro gathering systems.

NFG Midstream Clermont, LLC, a wholly owned subsidiary of Midstream Company, continues to develop an extensive gathering system with compression in the Pennsylvania counties of McKean, Elk and Cameron. The Clermont gathering system was initially placed in service in July 2014. The current system consists of three compressor stations and backbone and in-field gathering pipelines. The total cost estimate for the continued buildout will be dependent on the nature and timing of Seneca's long-term plans.

NFG Midstream Wellsboro, LLC, a wholly owned subsidiary of Midstream Company, continues to develop its Wellsboro gathering system in Tioga County, Pennsylvania. The current system consists of a dehydration and metering station and backbone and in-field gathering pipelines.

NFG Midstream Trout Run, LLC, a wholly owned subsidiary of Midstream Company, continues to develop its Trout Run gathering system in Lycoming County, Pennsylvania. The Trout Run gathering system was initially placed in service in May 2012. The current system consists of three compressor stations and backbone and in-field gathering pipelines. Midstream Company intends to extend this system in 2020. Combining this extension with reduced drilling activity in the Exploration and Production segment, the Gathering segment's capital expenditures are expected to be in the range of $50 million to $60 million for fiscal 2020. 

Utility 

The majority of the Utility segment capital expenditures for the three months ended December 31, 2019 and December 31, 2018 were made for main and service line improvements and replacements, as well as main extensions.  

Project Funding

Over the past two years, the Company has been financing the Pipeline and Storage segment and Gathering segment projects mentioned above, as well as the Exploration and Production segment and Utility segment capital expenditures, with cash from operations as well as proceeds received from the sale of oil and gas assets. Going forward, while the Company expects to use cash on hand, cash from operations and short-term debt to finance these projects, the Company may issue long-term debt as necessary during fiscal 2020 to help meet its capital expenditures needs. The level of short-term and long-term borrowings will depend upon the amount of cash provided by operations, which, in turn, will likely be impacted by natural gas and crude oil prices combined with production from existing wells. 

The Company continuously evaluates capital expenditures and potential investments in corporations, partnerships, and other business entities. The amounts are subject to modification for opportunities such as the acquisition of attractive oil and gas properties, natural gas storage facilities, natural gas gathering and compression facilities and the expansion of natural gas transmission line capacities, regulated utility assets and other opportunities as they may arise. While the majority of capital expenditures in the Utility segment are necessitated by the continued need for replacement and upgrading of mains and service lines, the magnitude of future capital expenditures or other investments in the Company’s other business segments depends, to a large degree, upon market conditions.

39

Financing Cash Flow

Consolidated short-term debt increased $84.6 million when comparing the balance sheet at December 31, 2019 to the balance sheet at September 30, 2019. The maximum amount of short-term debt outstanding during the quarter ended December 31, 2019 was $173.3 million. The Company continues to consider short-term debt (consisting of short-term notes payable to banks and commercial paper) an important source of cash for temporarily financing capital expenditures, gas-in-storage inventory, unrecovered purchased gas costs, margin calls on derivative financial instruments, exploration and development expenditures, other working capital needs and repayment of long-term debt. Fluctuations in these items can have a significant impact on the amount and timing of short-term debt. At December 31, 2019, the Company had outstanding commercial paper of $139.8 million. The Company did not have any outstanding short-term notes payable to banks at December 31, 2019.

On October 25, 2018, the Company entered into a Fourth Amended and Restated Credit Agreement (Credit Agreement) with a syndicate of 12 banks. This Credit Agreement provides a $750.0 million multi-year unsecured committed revolving credit facility through October 25, 2023. The Company also has uncommitted lines of credit with financial institutions for general corporate purposes. Borrowings under these uncommitted lines of credit would be made at competitive market rates. The uncommitted credit lines are revocable at the option of the financial institution and are reviewed on an annual basis. The Company anticipates that its uncommitted lines of credit generally will be renewed or substantially replaced by similar lines. Other financial institutions may also provide the Company with uncommitted or discretionary lines of credit in the future.

The total amount available to be issued under the Company’s commercial paper program is $500.0 million. The commercial paper program is backed by the Credit Agreement, which provides that the Company's debt to capitalization ratio will not exceed .65 at the last day of any fiscal quarter. For purposes of calculating the debt to capitalization ratio, the Company's total capitalization will be increased by adding back 50% of the aggregate after-tax amount of non-cash charges directly arising from any ceiling test impairment occurring on or after July 1, 2018, not to exceed $250 million. At December 31, 2019, the Company’s debt to capitalization ratio (as calculated under the facility) was .51. The constraints specified in the Credit Agreement would have permitted an additional $1.77 billion in short-term and/or long-term debt to be outstanding at December 31, 2019 (further limited by the indenture covenants discussed below) before the Company’s debt to capitalization ratio exceeded .65.

A downgrade in the Company’s credit ratings could increase borrowing costs, negatively impact the availability of capital from banks, commercial paper purchasers and other sources, and require the Company's subsidiaries to post letters of credit, cash or other assets as collateral with certain counterparties. If the Company is not able to maintain investment-grade credit ratings, it may not be able to access commercial paper markets. However, the Company expects that it could borrow under its credit facilities or rely upon other liquidity sources, including cash provided by operations.

The Credit Agreement contains a cross-default provision whereby the failure by the Company or its significant subsidiaries to make payments under other borrowing arrangements, or the occurrence of certain events affecting those other borrowing arrangements, could trigger an obligation to repay any amounts outstanding under the Credit Agreement. In particular, a repayment obligation could be triggered if (i) the Company or any of its significant subsidiaries fails to make a payment when due of any principal or interest on any other indebtedness aggregating $40.0 million or more or (ii) an event occurs that causes, or would permit the holders of any other indebtedness aggregating $40.0 million or more to cause, such indebtedness to become due prior to its stated maturity. As of December 31, 2019, the Company did not have any debt outstanding under the Credit Agreement.

None of the Company's long-term debt as of December 31, 2019 and September 30, 2019 had a maturity date within the following twelve-month period.

The Company’s embedded cost of long-term debt was 4.69% at both December 31, 2019 and December 31, 2018.

Under the Company’s existing indenture covenants at December 31, 2019, the Company would have been permitted to issue up to a maximum of $1.05 billion in additional long-term indebtedness at then current market interest rates in addition to being able to issue new indebtedness to replace maturing debt. The Company's present liquidity position is believed to be adequate to satisfy known demands. However, if the Company were to experience a significant loss in the future (for example, as a result of an impairment of oil and gas properties), it is possible, depending on factors including the magnitude of the loss, that these indenture covenants would restrict the Company's ability to issue additional long-term unsecured indebtedness for a period of up to nine calendar months, beginning with the fourth calendar month following the loss. This would not preclude the Company from issuing new indebtedness to replace maturing debt. Please refer to the Critical Accounting Estimates section above for a sensitivity analysis concerning commodity price changes and their impact on the ceiling test.

40

The Company’s 1974 indenture pursuant to which $99.0 million (or 4.6%) of the Company’s long-term debt (as of December 31, 2019) was issued, contains a cross-default provision whereby the failure by the Company to perform certain obligations under other borrowing arrangements could trigger an obligation to repay the debt outstanding under the indenture. In particular, a repayment obligation could be triggered if the Company fails (i) to pay any scheduled principal or interest on any debt under any other indenture or agreement or (ii) to perform any other term in any other such indenture or agreement, and the effect of the failure causes, or would permit the holders of the debt to cause, the debt under such indenture or agreement to become due prior to its stated maturity, unless cured or waived.

OTHER MATTERS

In addition to the legal proceedings disclosed in Part II, Item 1 of this report, the Company is involved in other litigation and regulatory matters arising in the normal course of business. These other matters may include, for example, negligence claims and tax, regulatory or other governmental audits, inspections, investigations or other proceedings. These matters may involve state and federal taxes, safety, compliance with regulations, rate base, cost of service and purchased gas cost issues, among other things. While these normal-course matters could have a material effect on earnings and cash flows in the period in which they are resolved, they are not expected to change materially the Company’s present liquidity position, nor are they expected to have a material adverse effect on the financial condition of the Company.

During the three months ended December 31, 2019, the Company contributed $7.8 million to its tax-qualified, noncontributory defined-benefit retirement plan (Retirement Plan) and $0.7 million to its VEBA trusts for its other post-retirement benefits.  In the remainder of 2020, the Company expects its contributions to the Retirement Plan to be in the range of $17.0 million to $22.0 million. In the remainder of 2020, the Company expects its contributions to its VEBA trusts to be in the range of $2.0 million to $2.5 million.

Market Risk Sensitive Instruments

On July 21, 2010, the Dodd-Frank Act was signed into law.  The Dodd-Frank Act includes provisions related to the swaps and over-the-counter derivatives markets that are designed to promote transparency, mitigate systemic risk and protect against market abuse.  Although regulators have issued certain regulations, other rules that may impact the Company have yet to be finalized.

The CFTC’s Dodd-Frank regulations continue to preserve the ability of non-financial end users to hedge their risks using swaps without being subject to mandatory clearing.  In 2015, legislation was enacted to exempt from margin requirements swaps used by non-financial end users to hedge or mitigate commercial risk.  In 2016, the CFTC issued a reproposal to its position limit rules that would impose speculative position limits on positions in 28 core physical commodity contracts as well as economically equivalent futures, options and swaps.  While the Company does not intend to enter into positions on a speculative basis, such rules could nevertheless impact the ability of the Company to enter into certain derivative hedging transactions with respect to such commodities.  If the Company reduces its use of hedging transactions as a result of final regulations to be issued by the CFTC, results of operations may become more volatile and cash flows may be less predictable.  There may be other rules developed by the CFTC and other regulators that could impact the Company.  While many of those rules place specific conditions on the operations of swap dealers and major swap participants, concern remains that swap dealers and major swap participants will pass along their increased costs stemming from final rules through higher transaction costs and prices or other direct or indirect costs.

Finally, given the additional authority granted to the CFTC on anti-market manipulation, anti-fraud and disruptive trading practices, it is difficult to predict how the evolving enforcement priorities of the CFTC will impact our business.  Should the Company violate any laws or regulations applicable to our hedging activities, it could be subject to CFTC enforcement action and material penalties and sanctions.  The Company continues to monitor these enforcement and other regulatory developments, but cannot predict the impact that evolving application of the Dodd-Frank Act may have on its operations.

The accounting rules for fair value measurements and disclosures require consideration of the impact of nonperformance risk (including credit risk) from a market participant perspective in the measurement of the fair value of assets and liabilities.  At December 31, 2019, the Company determined that nonperformance risk would have no material impact on its financial position or results of operation.  To assess nonperformance risk, the Company considered information such as any applicable collateral posted, master netting arrangements, and applied a market-based method by using the counterparty's (assuming the derivative is in a gain position) or the Company’s (assuming the derivative is in a loss position) credit default swaps rates.

For a complete discussion of market risk sensitive instruments, refer to "Market Risk Sensitive Instruments" in Item 7 of the Company's 2019 Form 10-K.  There have been no subsequent material changes to the Company’s exposure to market risk sensitive instruments.

Rate and Regulatory Matters

Utility Operation

Delivery rates for both the New York and Pennsylvania divisions are regulated by the states’ respective public utility commissions and typically are changed only when approved through a procedure known as a “rate case.” The Pennsylvania division does not have a rate case on file. See below for a description of the current rate proceedings affecting the New York division.  In both jurisdictions, delivery rates do not reflect the recovery of purchased gas costs. Prudently-incurred gas costs are recovered through operation of automatic adjustment clauses, and are collected primarily through a separately-stated “supply charge” on the customer bill.

New York Jurisdiction

Distribution Corporation's current delivery rates in its New York jurisdiction were approved by the NYPSC in an order issued on April 20, 2017 with rates becoming effective May 1, 2017. The order directed the implementation of an earnings sharing mechanism to be in place beginning on April 1, 2018.

On April 24, 2019, the NYPSC issued an order extending the sunset provision of the tracker previously approved by the NYPSC that allows Distribution Corporation to recover increased investment in utility system modernization for one year (until March 31, 2021). The extension is contingent on a one year stay-out of a general rate case filing that would prevent new rates from becoming effective prior to April 1, 2021.

Pennsylvania Jurisdiction

Distribution Corporation’s Pennsylvania jurisdiction delivery rates are being charged to customers in accordance with a rate settlement approved by the PaPUC. The rate settlement does not specify any requirement to file a future rate case.

Pipeline and Storage

Supply Corporation filed a Section 4 rate case on July 31, 2019 proposing rate increases to be effective September 1, 2019. The proposed rates reflect an annual cost of service of $295.4 million, a rate base of $970.8 million and a proposed cost of equity of 15%. The FERC has accepted the filed rates and suspended the effective date of the increases until February 1, 2020, when the rates will be made effective, subject to refund. If the rates finally approved at the end of the proceeding exceed the rates that were in effect at July 31, 2019, but are less than rates put into effect subject to refund on February 1, 2020, Supply Corporation would be required to refund the difference between the rates collected subject to refund and the final approved rates, with interest at the FERC-approved rate. If the rates approved at the end of the proceeding are lower than the rates in effect at July 31, 2019, such lower rates will become effective prospectively from the date of the applicable FERC order, and refunds with interest will be limited to the difference between the rates collected subject to refund and the rates in effect at July 31, 2019.

Empire's 2019 rate settlement requires a Section 4 rate case filing no later than May 1, 2025. Empire has no rate case currently on file.

Environmental Matters

The Company is subject to various federal, state and local laws and regulations relating to the protection of the environment.  The Company has established procedures for the ongoing evaluation of its operations to identify potential environmental exposures and comply with regulatory requirements. 

For further discussion of the Company's environmental exposures, refer to Item 1 at Note 8 — Commitments and Contingencies under the heading “Environmental Matters.”

Legislative and regulatory measures to address climate change and greenhouse gas emissions are in various phases of discussion or implementation in the United States. These efforts include legislative proposals and new regulations at the state and federal level, and private party litigation related to greenhouse gas emissions. The U.S. Congress has not yet passed any federal climate change legislation and we cannot predict when or if Congress will pass such legislation and in what form. In the absence of such legislation, the EPA regulates greenhouse gas emissions pursuant to the Clean Air Act. The regulations implemented by EPA impose more stringent leak detection and repair requirements, and further address reporting and control of methane and volatile organic compound emissions. The current administration has issued executive orders to review and potentially roll back

42

many of these burdensome regulations, and, in turn, litigation (not involving the Company) has been instituted to challenge the administration's efforts. The Company must continue to comply with all applicable regulations. A number of states have adopted energy strategies or plans with aggressive goals for the reduction of greenhouse gas emissions. Pennsylvania has a methane reduction framework with the stated goal of reducing methane emissions from well sites, compressor stations and pipelines and is in the process of evaluating cap-and-trade programs (e.g., Regional Greenhouse Gas Initiative). In California, the Company currently complies with California cap-and-trade rules, which increases the Company's cost of environmental compliance in its Exploration and Production segment. Legislation or regulation that aims to reduce greenhouse gas emissions could also include emissions limits, reporting requirements, carbon taxes, restrictive permitting, increased efficiency standards, and incentives or mandates to conserve energy or use renewable energy sources. Federal, state or local governments may provide tax advantages and other subsidies to support alternative energy sources, mandate the use of specific fuels or technologies, or promote research into new technologies to reduce the cost and increase the scalability of alternative energy sources. New York State, for example, passed the CLCPA that mandates reducing greenhouse gas emissions to 60% of 1990 levels by 2030, and to 15% of 1990 levels by 2050, with the remaining emission reduction achieved by controlled offsets. The CLCPA also requires electric generators to meet 70% of demand with renewable energy by 2030 and 100% by 2040. These climate change and greenhouse gas initiatives could impact the Company's customer base and assets depending on regulatory treatment afforded in the process. These initiatives could also increase the Company’s cost of environmental compliance by increasing reporting requirements, requiring retrofitting of existing equipment, requiring installation of new equipment, and/or requiring the purchase of emission allowances. They could also delay or otherwise negatively affect efforts to obtain permits and other regulatory approvals. Changing market conditions and new regulatory requirements, as well as unanticipated or inconsistent application of existing laws and regulations by administrative agencies, make it difficult to predict a long-term business impact across twenty or more years.

Safe Harbor for Forward-Looking Statements

The Company is including the following cautionary statement in this Form 10-Q to make applicable and take advantage of the safe harbor provisions of the Private Securities Litigation Reform Act of 1995 for any forward-looking statements made by, or on behalf of, the Company.

In addition to other factors and matters discussed elsewhere herein, the following are important factors that, in the view of the Company, could cause actual results to differ materially from those discussed in the forward-looking statements:

1. Changes in the price of natural gas or oil;

2. Impairments under the SEC’s full cost ceiling test for natural gas and oil reserves;

3. Changes in laws, regulations or judicial interpretations to which the Company is subject, including those involving derivatives, taxes, safety, employment, climate change, other environmental matters, real property, and exploration and production activities such as hydraulic fracturing;

4. Delays or changes in costs or plans with respect to Company projects or related projects of other companies, including difficulties or delays in obtaining necessary governmental approvals, permits or orders or in obtaining the cooperation of interconnecting facility operators;

5. Governmental/regulatory actions, initiatives and proceedings, including those involving rate cases (which address, among other things, target rates of return, rate design and retained natural gas), environmental/safety requirements, affiliate relationships, industry structure, and franchise renewal;

6. Changes in price differentials between similar quantities of natural gas or oil at different geographic locations, and the effect of such changes on commodity production, revenues and demand for pipeline transportation capacity to or from such locations;

43

7. Financial and economic conditions, including the availability of credit, and occurrences affecting the Company’s ability to obtain financing on acceptable terms for working capital, capital expenditures and other investments, including any downgrades in the Company’s credit ratings and changes in interest rates and other capital market conditions;

8. Factors affecting the Company’s ability to successfully identify, drill for and produce economically viable natural gas and oil reserves, including among others geology, lease availability, title disputes, weather conditions, shortages, delays or unavailability of equipment and services required in drilling operations, insufficient gathering, processing and transportation capacity, the need to obtain governmental approvals and permits, and compliance with environmental laws and regulations;

9. Increasing health care costs and the resulting effect on health insurance premiums and on the obligation to provide other post-retirement benefits; 

10. Other changes in price differentials between similar quantities of natural gas or oil having different quality, heating value, hydrocarbon mix or delivery date;

11. The cost and effects of legal and administrative claims against the Company or activist shareholder campaigns to effect changes at the Company;

12. Uncertainty of oil and gas reserve estimates;

Exhibit 10.1

Form of Award Notice for Return on Capital Performance Shares under

the National Fuel Gas Company 2010 Equity Compensation Plan

Name

Address

Dear _________:

I am pleased to inform you that on [date of grant] the Compensation Committee (“Committee”) of the Board of Directors of National Fuel Gas Company (the “Company”) granted to you (the “Grantee” or “you”) ____ Performance Shares under the National Fuel Gas Company 2010 Equity Compensation Plan (the “Plan”), subject to a Performance Goal related to return on capital, as set forth in this Award Notice. Performance Shares are an award, pursuant to Section 9 of the Plan, constituting units denominated in Common Stock, the number of which such units may be adjusted over a Performance Cycle based upon the extent to which Performance Goals have been satisfied.

The Performance Shares covered by this letter agreement (“Award Notice”) may be referred to in this Award Notice as “Your ROC Performance Shares.” The number of Performance Shares set forth above is referred to in this Award Notice as the “Target Opportunity.” The Plan and the Committee’s Administrative Rules (“Rules”) govern the operation of the Plan, as well as the terms and conditions of Your ROC Performance Shares, and are incorporated herein by reference. Capitalized terms not otherwise defined herein shall have the meanings set forth for such terms in the Plan or the Rules.

1.    Performance Cycle and Performance Goal

The vesting of Your ROC Performance Shares is subject to a Performance Goal as set forth in this Award Notice. The Performance Cycle for Your ROC Performance Shares is [start date] through [end date]. Except as otherwise specified in the Plan or determined by the Committee, and to the extent the Performance Goal has been achieved, Your ROC Performance Shares shall vest on such date as the Committee determines the extent to which the Performance Goal has been achieved. Such determination date shall be not later than [date].

The Performance Goal upon which any vesting and payment of Your ROC Performance Shares is conditioned shall be the Total Return on Capital (as defined below) of the Company over the Performance Cycle relative to the Total Return on Capital of other companies in the Report Group (as defined below) for the Performance Cycle. Total Return on Capital for the Company or any member of the Report Group shall mean the average of the returns on capital for each twelve month period corresponding to each of the Company’s fiscal years during the

Performance Cycle, based on the data reported for that companyin the Bloomberg online database (or, if the Bloomberg database ceases to be available, such alternative publication or service as the Compensation Committee shall designate) for the following group of companies for which data is available for the entire Performance Cycle (the “Report Group”):

Atmos Energy Corporation

Cabot Oil & Gas Corporation

CNX Resources Corporation

EQT Corporation

MDU Resources Group Inc.

National Fuel Gas Company

New Jersey Resources Corporation

Range Resources Corporation

SM Energy Company

Southwest Gas Holdings, Inc.

Southwestern Energy Company

Spire Inc.

UGI Corporation

Whiting Petroleum Corporation

Notwithstanding the foregoing, in comparing the Company’s performance to that of the Report Group, the Committee shall adjust the Company’s Total Return on Capital to include the effect of discontinued operations. To the extent reasonably correctible, the Committee shall correct the reported data for a known error in the reporting of the results of the Company. Furthermore, to the extent a company in the Report Group ceases to exist due to bankruptcy, delisting, liquidation or any other reason as determined and approved by the Committee, that company shall not be removed from the Report Group and shall be considered to have performed at a level ranking it at the bottom of the Report Group.

The term “Percentile Ranking” as used in this Award Notice in reference to Total Return on Capital means the percentage determined by dividing:

(A) the remainder of the Company’s rank within the Report Group for the Performance Cycle (measured lowest to highest) based on its Total Return on Capital for the Performance Cycle, minus one (1),

by

(B) the number of companies (excluding the Company) in the Report Group for that Performance Cycle.

For purposes of determining the Company’s rank within the Report Group, if the Company’s Total Return on Capital for a Performance Cycle equals that of another company in the Report Group, the Company shall be ranked ahead of such other company.

Your ROC Performance Shares shall vest and payment shall be made on Your ROC Performance Shares to the extent the Company achieves the Percentile Ranking detailed below,

provided that Your ROC Performance Shares have not previously been forfeited in accordance with applicable terms and conditions.

Company’s Percentile Ranking	Percentage of Target Opportunity Paid
< 45th	0%
45th	50%
60th	100%
75th	150%
100th	200%

Notwithstanding the foregoing, if the Company’s Total Return on Capital is negative (less than 0.0), the percentage of Target Opportunity paid shall be capped at 100%. For performance between two established performance levels, the percentage of Target Opportunity paid will be determined by mathematical interpolation.

Any and all of Your ROC Performance Shares representing the percentage of the Target Opportunity not required to be paid shall not vest, and shall be automatically forfeited on the datethe Compensation Committee makes its determination as to the extent to which the Performance Goal has been achieved, but no later than [date], if not previously forfeited in accordance with the terms and conditions applicable to such Performance Shares.

2.    Settlement

At the expiration of the Performance Cycle, the Committee shall certify in writing the number of Performance Shares earned and vested on the basis of performance in relation to the Performance Goal. The Committee shall determine whether earned Performance Shares are to be distributed in the form of cash, shares of Common Stock or in a combination thereof, with the value or number of shares payable to be determined based on the Fair Market Value of the Common Stock on the date of the Committee’s certification. Any fractional share otherwise payable in settlement of Your ROC Performance Shares shall be paid in cash.

3.    Restrictions on Transferability

Your ROC Performance Shares may not be sold, assigned, transferred or pledged during the Performance Cycle, except that the Committee may permit (on such terms and conditions as it shall establish) some or all of Your ROC Performance Shares to be transferred during the Performance Cycle to a Permitted Transferee in accordance with Section 14(a) of the Plan.

4.    Rights as a Shareholder

You shall not have any right, in respect of Your ROC Performance Shares, to vote on any matter submitted to the Company’s stockholders until such time, if any, as the shares of Common Stock attributable to Your ROC Performance Shares have been issued. Dividend Equivalents shall not be paid or payable on Your ROC Performance Shares before they become earned and vested.

5.    Termination of Employment

In the event your employment with the Company or its Subsidiaries terminates due to your death, Disability or Retirement, or due to the Company divestiture of one or more Subsidiaries or other business segments, divisions or operations in a transaction that does not otherwise qualify as a Change in Control, then the number of Your ROC Performance Shares that otherwise would have vested after the end of the Performance Cycle shall be pro-rated to reflect the time period from the commencement of the Performance Cycle through the date of the termination of your service to the Company or its Subsidiaries, as described in Sections 11(a)(i) and 11(c)(i), respectively, of the Plan, and any of Your ROC Performance Shares that do not vest shall automatically be forfeited. In the event your employment with the Company or its Subsidiaries terminates for any other reason, the provisions of the Plan shall control.

6.    Change in Control

Subject to the terms of the Plan and the Rules, in the event of a Change in Control of the Company, each of Your ROC Performance Shares then outstanding shall be deemed earned at the target level of performance for such Award. In addition, the Committee may direct that each of Your ROC Performance Shares be settled in cash with its value determined based on the value received by the shareholders in any transaction that constitutes a Change in Control. The Plan also allows the Committee to reasonably determine in good faith, before a Change in Control, that this Award shall be honored or assumed, or new rights substituted therefore, by your employer or the parent or affiliate of your employer, provided that any such honored, assumed or substituted award must satisfy the requirements set forth in Section 12(b) of the Plan, including “substantially equivalent economic value.”

7.    Adjustments in Common Stock

In the event of an Adjustment Event, including any stock dividend, stock split, merger, consolidation, reorganization, recapitalization or other similar event affecting the Common Stock, the Committee shall equitably adjust, in its discretion, the number of shares subject to this Award Notice. To the extent the Committee deems equitable and appropriate and subject to any required action by shareholders of the Company or of any successor in interest to the Company or any direct or indirect parent corporation of the Company or any such successor, in any Adjustment Event that is a merger, consolidation, reorganization, liquidation, dissolution or similar transaction, Your ROC Performance Shares shall be deemed to pertain to the securities and other property, including cash, to which a holder of the number of shares of Common Stock covered by this Award Notice would have been entitled to receive in connection with such Adjustment Event. Any Committee determination pursuant to this Section 7 shall be final, binding and conclusive.

8.    Authority of Committee

The Committee has the authority to interpret the Plan and all Performance Shares granted thereunder, to establish rules and regulations relating to the Plan and to make all other determinations it believes necessary or advisable for the administration of the Plan. The scope of

the Committee’s authority is more fully described in Section 3 of the Plan. All determinations and actions of the Committee are final, conclusive and binding on you.

9.    Miscellaneous

(a)    This Award Notice shall be binding upon and inure to the benefit of the Company (and its successors and assigns) and you (and your heirs, legal representatives and estate) and shall be governed by the laws of the State of New Jersey, and any applicable laws of the United States. The Performance Share award under the Plan does not alter, amend or otherwise affect your employment status with the Company or its subsidiaries. No contract or right of employment shall be implied by this Award Notice.

(b)    The Committee may at any time unilaterally amend any unpaid Performance Shares award, including Awards earned but not yet paid, to the extent it deems appropriate, provided, however, that subject to Section 5(d) of the Plan, any such amendment which is adverse to the Grantee shall require the Grantee’s consent unless the Committee determines that such amendment or modification is necessary or advisable to comply with applicable law as a result of changes in law or regulation or to avoid the imposition of an additional tax, interest or penalty under Section 409A of the Internal Revenue Code of 1986, as amended.

(c)    If Your ROC Performance Shares are assumed or new Performance Shares are substituted therefor in any corporate reorganization (including, but not limited to, any transaction of the type referred to in Section 424(a) of the Internal Revenue Code of 1986, as amended), employment by such assuming or substituting company or by a parent company or a subsidiary thereof shall be considered for all purposes of this Award Notice to be employment by the Company.

(d)    In consideration of the Grantee’s privilege to participate in the Plan, the Grantee agrees (i) not to disclose any trade secrets of, or other confidential/restricted information of the Company to any unauthorized party, (ii) not to make any unauthorized use of such trade secrets or confidential or restricted information during his or her employment with the Company or its Subsidiaries or after such employment is terminated, and (iii) not to solicit any then current employees of the Company or any other subsidiaries of the Company to join the Grantee at his or her new place of employment after his or her employment with the Company or its Subsidiaries is terminated. Pursuant to 18 U.S.C. § 1833(b), an individual shall not be held criminally or civilly liable under any federal or state trade secret law for the disclosure of a trade secret that is made: (1) in confidence to a Federal, State, or local government official, either directly or indirectly, or to an attorney, and solely for the purpose of reporting or investigating a suspected violation of law; or (2) in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal. Additionally, an individual who files a lawsuit for retaliation by an employer for reporting a suspected violation of law may disclose a trade secret to his or her attorney and use the trade secret information in the court proceeding, if the individual: (1) files any document containing the trade secret under seal; and (2) does not disclose the trade secret, except pursuant to court order.

(e)    This Award Notice, together with the Plan and the Rules, constitutes the entire agreement between the parties with respect to the subject matter hereof. You hereby acknowledge that you have been provided with a copy of the Plan and the Rules, and understand the terms and conditions of these documents and of this Award Notice.

(f)    In the event of the invalidity of any part or provision of this Award Notice, such invalidity shall not affect the enforceability of any other part or provision hereof.

10.    Tax Withholding

The Company will be entitled to deduct from any payment under this Award Notice, regardless of the form of such payment, the amount of all applicable income and employment taxes required by law to be withheld with respect to such payment or may require you to pay to it such tax prior to and as a condition of the making of such payment. Tax withholdings will be in accordance with the Rules.

11.    Securities Law Requirements

The Company will not be required to issue shares in settlement of Your ROC Performance Shares unless and until (a) such shares have been duly listed upon each stock exchange on which the Company’s Common Stock is then registered and (b) a registration statement under the Securities Act of 1933 with respect to such shares is then effective. The Board may require you to furnish to the Company, prior to the issuance of any shares of Common Stock in connection with the settlement of Your ROC Performance Shares, an agreement, in such form as the Board may from time to time deem appropriate, in which you represent that the shares you acquired upon such settlement are being acquired for investment and not with a view to the sale or distribution thereof.

12.    Performance Shares Subject to Plan and Rules

Your ROC Performance Shares shall be subject to all the terms and provisions of the Plan, the Rules and this Award Notice, and you shall abide by and be bound by such terms and provisions and all rules, regulations and determinations of the Board or the Committee now or hereafter made in its discretion in connection with the administration of the Plan.

13.    American Jobs Creation Act

In addition to amendments permitted by Section 9(b) above, the Company may make amendments to Your ROC Performance Shares, without your consent, in order to ensure compliance with the American Jobs Creation Act of 2004.

Performance Shares are an award, pursuant to Section 9 of the Plan, constituting units denominated in Common Stock, the number of which such units may be adjusted over a Performance Cycle based upon the extent to which Performance Goals have been satisfied.

The Performance Shares covered by this letter agreement (“Award Notice”) may be referred to in this Award Notice as “Your TSR Performance Shares.” The number of Performance Shares set forth above is referred to in this Award Notice as the “Target Opportunity.” The Plan and the Committee’s Administrative Rules (“Rules”) govern the operation of the Plan, as well as the terms and conditions of Your TSR Performance Shares, and are incorporated herein by reference. Capitalized terms not otherwise defined herein shall have the meanings set forth for such terms in the Plan or the Rules.

1.    Performance Cycle and Performance Goal

The vesting of Your TSR Performance Shares is subject to a Performance Goal as set forth in this Award Notice. The Performance Cycle for Your TSR Performance Shares is [start date] through [end date]. Except as otherwise specified in the Plan or determined by the Committee, and to the extent the Performance Goal has been achieved, Your TSR Performance Shares shall vest on such date as the Committee determines the extent to which the Performance Goal has been achieved. Such determination date shall be not later than [date].

The Performance Goal upon which any vesting and payment of Your TSR Performance Shares is conditioned shall be the Three-Year Total Shareholder Return (as defined below) of the Company over the Performance Cycle relative to the Three-Year Total Shareholder Return of other companies in the Report Group (as defined below) for the Performance Cycle. Three-Year Total Shareholder Return for the Company or any member of the Report Group shall be based on the data reported for that company(with the starting and ending stock prices over the Performance Cycle calculated as the average closing stock price for the prior calendar month and with dividends reinvested in that company’s securities at each ex-dividend date) in the

To the extent reasonably correctible, the Committee shall correct the reported data for a known error in the reporting of the results of the Company. Furthermore, to the extent a company in the Report Group ceases to exist due to bankruptcy, delisting, liquidation or any other reason as determined and approved by the Committee, that company shall not be removed from the Report Group and shall be considered to have performed at a level ranking it at the bottom of the Report Group.

The term “Percentile Ranking” as used in this Award Notice in reference to Three-Year Total Shareholder Return means the percentage determined by dividing:

(A) the remainder of the Company’s rank within the Report Group for the Performance Cycle (measured lowest to highest) based on its Three-Year Total Shareholder Return for the Performance Cycle, minus one (1),

by

(B) the number of companies (excluding the Company) in the Report Group for that Performance Cycle.

For purposes of determining the Company’s rank within the Report Group, if the Company’s Three-Year Total Shareholder Return for a Performance Cycle equals that of another company in the Report Group, the Company shall be ranked ahead of such other company.

Your TSR Performance Shares shall vest and payment shall be made on Your TSR Performance Shares to the extent the Company achieves the Percentile Ranking detailed below, provided that Your TSR Performance Shares have not previously been forfeited in accordance with applicable terms and conditions.

Company’s Percentile Ranking	Percentage of Target Opportunity Paid
30th or below	0%
40th	50%
50th	100%
70th	150%
90th or above	200%

Notwithstanding the foregoing, if the Company’s Three-Year Total Shareholder Return is negative (less than 0.0), the percentage of Target Opportunity paid shall be capped at 100%. For performance between two established performance levels, the percentage of Target Opportunity paid will be determined by mathematical interpolation.

Any and all of Your TSR Performance Shares representing the percentage of the Target Opportunity not required to be paid shall not vest, and shall be automatically forfeited on the datethe Compensation Committee makes its determination as to the extent to which the Performance Goal has been achieved, but no later than [date], if not previously forfeited in accordance with the terms and conditions applicable to such Performance Shares.

2.    Settlement

At the expiration of the Performance Cycle, the Committee shall certify in writing the number of Performance Shares earned and vested on the basis of performance in relation to the Performance Goal. The Committee shall determine whether earned Performance Shares are to be distributed in the form of cash, shares of Common Stock or in a combination thereof, with the value or number of shares payable to be determined based on the Fair Market Value of the Common Stock on the date of the Committee’s certification. Any fractional share otherwise payable in settlement of Your TSR Performance Shares shall be paid in cash.

3.    Restrictions on Transferability

Your TSR Performance Shares may not be sold, assigned, transferred or pledged during the Performance Cycle, except that the Committee may permit (on such terms and conditions as it shall establish) some or all of Your TSR Performance Shares to be transferred during the Performance Cycle to a Permitted Transferee in accordance with Section 14(a) of the Plan.

4.    Rights as a Shareholder

You shall not have any right, in respect of Your TSR Performance Shares, to vote on any matter submitted to the Company’s stockholders until such time, if any, as the shares of Common Stock attributable to Your TSR Performance Shares have been issued. Dividend Equivalents shall not be paid or payable on Your TSR Performance Shares before they become earned and vested.

5.    Termination of Employment

In the event your employment with the Company or its Subsidiaries terminates due to your death, Disability or Retirement, or due to the Company divestiture of one or more Subsidiaries or other business segments, divisions or operations in a transaction that does not otherwise qualify as a Change in Control, then the number of Your TSR Performance Shares that otherwise would have vested after the end of the Performance Cycle shall be pro-rated to reflect the time period from the commencement of the Performance Cycle through the date of the termination of your service to the Company or its Subsidiaries, as described in Sections 11(a)(i) and 11(c)(i), respectively, of the Plan, and any of Your TSR Performance Shares that do not vest shall automatically be forfeited. In the event your employment with the Company or its Subsidiaries terminates for any other reason, the provisions of the Plan shall control.

6.    Change in Control

Subject to the terms of the Plan and the Rules, in the event of a Change in Control of the Company, each of Your TSR Performance Shares then outstanding shall be deemed earned at the target level of performance for such Award. In addition, the Committee may direct that each of Your TSR Performance Shares be settled in cash with its value determined based on the value received by the shareholders in any transaction that constitutes a Change in Control. The Plan also allows the Committee to reasonably determine in good faith, before a Change in Control, that this Award shall be honored or assumed, or new rights substituted therefore, by your employer or the parent or affiliate of your employer, provided that any such honored, assumed or substituted award must satisfy the requirements set forth in Section 12(b) of the Plan, including “substantially equivalent economic value.”

7.    Adjustments in Common Stock

In the event of an Adjustment Event, including any stock dividend, stock split, merger, consolidation, reorganization, recapitalization or other similar event affecting the Common Stock, the Committee shall equitably adjust, in its discretion, the number of shares subject to this Award Notice. To the extent the Committee deems equitable and appropriate and subject to any required action by shareholders of the Company or of any successor in interest to the Company or any direct or indirect parent corporation of the Company or any such successor, in any Adjustment Event that is a merger, consolidation, reorganization, liquidation, dissolution or similar transaction, Your TSR Performance Shares shall be deemed to pertain to the securities and other property, including cash, to which a holder of the number of shares of Common Stock covered by this Award Notice would have been entitled to receive in connection with such Adjustment Event. Any Committee determination pursuant to this Section 7 shall be final, binding and conclusive.

8.    Authority of Committee

the Committee’s authority is more fully described in Section 3 of the Plan. All determinations and actions of the Committee are final, conclusive and binding on you.

9.    Miscellaneous

(a)    This Award Notice shall be binding upon and inure to the benefit of the Company (and its successors and assigns) and you (and your heirs, legal representatives and estate) and shall be governed by the laws of the State of New Jersey, and any applicable laws of the United States. The Performance Share award under the Plan does not alter, amend or otherwise affect your employment status with the Company or its subsidiaries. No contract or right of employment shall be implied by this Award Notice.

(b)    The Committee may at any time unilaterally amend any unpaid Performance Shares award, including Awards earned but not yet paid, to the extent it deems appropriate, provided, however, that subject to Section 5(d) of the Plan, any such amendment which is adverse to the Grantee shall require the Grantee’s consent unless the Committee determines that such amendment or modification is necessary or advisable to comply with applicable law as a result of changes in law or regulation or to avoid the imposition of an additional tax, interest or penalty under Section 409A of the Internal Revenue Code of 1986, as amended.

(c)    If Your TSR Performance Shares are assumed or new Performance Shares are substituted therefor in any corporate reorganization (including, but not limited to, any transaction of the type referred to in Section 424(a) of the Internal Revenue Code of 1986, as amended), employment by such assuming or substituting company or by a parent company or a subsidiary thereof shall be considered for all purposes of this Award Notice to be employment by the Company.

(d)    In consideration of the Grantee’s privilege to participate in the Plan, the Grantee agrees (i) not to disclose any trade secrets of, or other confidential/restricted information of the Company to any unauthorized party, (ii) not to make any unauthorized use of such trade secrets or confidential or restricted information during his or her employment with the Company or its Subsidiaries or after such employment is terminated, and (iii) not to solicit any then current employees of the Company or any other subsidiaries of the Company to join the Grantee at his or her new place of employment after his or her employment with the Company or its Subsidiaries is terminated. Pursuant to 18 U.S.C. § 1833(b), an individual shall not be held criminally or civilly liable under any federal or state trade secret law for the disclosure of a trade secret that is made: (1) in confidence to a Federal, State, or local government official, either directly or indirectly, or to an attorney, and solely for the purpose of reporting or investigating a suspected violation of law; or (2) in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal. Additionally, an individual who files a lawsuit for retaliation by an employer for reporting a suspected violation of law may disclose a trade secret to his or her attorney and use the trade secret information in the court proceeding, if the individual: (1) files any document containing the trade secret under seal; and (2) does not disclose the trade secret, except pursuant to court order.

(e)    This Award Notice, together with the Plan and the Rules, constitutes the entire agreement between the parties with respect to the subject matter hereof. You hereby acknowledge that you have been provided with a copy of the Plan and the Rules, and understand the terms and conditions of these documents and of this Award Notice.

(f)    In the event of the invalidity of any part or provision of this Award Notice, such invalidity shall not affect the enforceability of any other part or provision hereof.

10.    Tax Withholding

The Company will be entitled to deduct from any payment under this Award Notice, regardless of the form of such payment, the amount of all applicable income and employment taxes required by law to be withheld with respect to such payment or may require you to pay to it such tax prior to and as a condition of the making of such payment. Tax withholdings will be in accordance with the Rules.

11.    Securities Law Requirements

The Company will not be required to issue shares in settlement of Your TSR Performance Shares unless and until (a) such shares have been duly listed upon each stock exchange on which the Company’s Common Stock is then registered and (b) a registration statement under the Securities Act of 1933 with respect to such shares is then effective. The Board may require you to furnish to the Company, prior to the issuance of any shares of Common Stock in connection with the settlement of Your TSR Performance Shares, an agreement, in such form as the Board may from time to time deem appropriate, in which you represent that the shares you acquired upon such settlement are being acquired for investment and not with a view to the sale or distribution thereof.

12.    Performance Shares Subject to Plan and Rules

Your TSR Performance Shares shall be subject to all the terms and provisions of the Plan, the Rules and this Award Notice, and you shall abide by and be bound by such terms and provisions and all rules, regulations and determinations of the Board or the Committee now or hereafter made in its discretion in connection with the administration of the Plan.

13.    American Jobs Creation Act

In addition to amendments permitted by Section 9(b) above, the Company may make amendments to Your TSR Performance Shares, without your consent, in order to ensure compliance with the American Jobs Creation Act of 2004. And, further, amendments may be made to the Plan to ensure such compliance, which amendments may impact Your TSR Performance Shares.

Fair Value Measurements

Fair Value Disclosures [Abstract]

Fair Value Measurements

Fair Value Measurements

The FASB authoritative guidance regarding fair value measurements establishes a fair-value hierarchy and prioritizes the inputs used in valuation techniques that measure fair value. Those inputs are prioritized into three levels. Level 1 inputs are unadjusted quoted prices in active markets for assets or liabilities that the Company can access at the measurement date. Level 2 inputs are inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly at the measurement date. Level 3 inputs are unobservable inputs for the asset or liability at the measurement date. The Company’s assessment of the significance of a particular input to the fair value measurement requires judgment, and may affect the valuation of fair value assets and liabilities and their placement within the fair value hierarchy levels.

The following table sets forth, by level within the fair value hierarchy, the Company's financial assets and liabilities (as applicable) that were accounted for at fair value on a recurring basis as of December 31, 2019 and September 30, 2019.  Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The fair value presentation for over the counter swaps combines gas and oil swaps because a significant number of the counterparties enter into both gas and oil swap agreements with the Company.

⁽¹⁾  Netting Adjustments represent the impact of legally-enforceable master netting arrangements that allow the Company to net gain and loss positions held with the same counterparties. The net asset or net liability for each counterparty is recorded as an asset or liability on the Company’s balance sheet.

Derivative Financial Instruments

At December 31, 2019 and September 30, 2019, the derivative financial instruments reported in Level 1 consist of natural gas NYMEX and ICE futures contracts used by NFR (included in the All Other category). Hedging collateral deposits of $9.7 million (at December 31, 2019) and $6.8 million (at September 30, 2019), which were associated with these futures contracts, have been reported in Level 1 as well. The derivative financial instruments reported in Level 2 at December 31, 2019 and September 30, 2019 consist of natural gas price swap agreements used in the Company’s Exploration and Production segment and in its NFR operations, crude oil price swap agreements used in the Company’s Exploration and Production segment, basis hedge swap agreements used by NFR and foreign currency contracts used in the Company's Exploration and Production segment. The fair value of the Level 2 price swap agreements is based on an internal, discounted cash flow model that uses observable inputs (i.e. LIBOR based discount rates and basis differential information, if applicable, at active natural gas and crude oil trading markets). The fair value of the Level 2 foreign currency contracts is determined using the market approach based on observable market transactions of forward Canadian currency rates. 

The accounting rules for fair value measurements and disclosures require consideration of the impact of nonperformance risk (including credit risk) from a market participant perspective in the measurement of the fair value of assets and liabilities.  At December 31, 2019, the Company determined that nonperformance risk would have no material impact on its financial position or results of operation.  To assess nonperformance risk, the Company considered information such as any applicable collateral posted, master netting arrangements, and applied a market-based method by using the counterparty's (assuming the derivative is in a gain position) or the Company’s (assuming the derivative is in a loss position) credit default swaps rates.

For the quarters ended December 31, 2019 and December 31, 2018, there were no assets or liabilities measured at fair value and classified as Level 3. For the quarters ended December 31, 2019 and December 31, 2018, no transfers in or out of Level 1 or Level 2 occurred.

Commitments And Contingencies

Commitments and Contingencies Disclosure [Abstract]

Commitments And Contingencies

Commitments and Contingencies

Environmental Matters.  The Company is subject to various federal, state and local laws and regulations relating to the protection of the environment.  The Company has established procedures for the ongoing evaluation of its operations to identify potential environmental exposures and to comply with regulatory requirements.  It is the Company’s policy to accrue estimated environmental clean-up costs (investigation and remediation) when such amounts can reasonably be estimated and it is probable that the Company will be required to incur such costs. 

At December 31, 2019, the Company has estimated its remaining clean-up costs related to former manufactured gas plant sites will be approximately $6.9 million, which includes a $3.7 million estimated minimum liability to remediate a former

manufactured gas plant site located in New York.  In March 2018, the NYDEC issued a Record of Decision for this New York site and the minimum liability reflects the remedy selected in the Record of Decision. The Company's liability for such clean-up costs has been recorded in Other Deferred Credits on the Consolidated Balance Sheet at December 31, 2019. The Company expects to recover its environmental clean-up costs through rate recovery over a period of approximately 3 years and is currently not aware of any material additional exposure to environmental liabilities.  However, changes in environmental laws and regulations, new information or other factors could have an adverse financial impact on the Company.

Northern Access Project. On February 3, 2017, Supply Corporation and Empire received FERC approval of the Northern Access project described herein. Shortly thereafter, the NYDEC issued a Notice of Denial of the federal Clean Water Act Section 401 Water Quality Certification and other state stream and wetland permits for the New York portion of the project (the Water Quality Certification for the Pennsylvania portion of the project was received in January of 2017). The United States Court of Appeals for the Second Circuit (the “Second Circuit Court of Appeals”) held in the Company’s favor in its appeal of this decision, vacating the NYDEC denial and remanding to the NYDEC. The NYDEC subsequently issued a second denial, which the Company has appealed to the Second Circuit Court of Appeals. The court has held this appeal in abeyance pending the outcome of the FERC waiver appeal, described below. While the Company’s initial appeal was pending before the Second Circuit Court of Appeals, the FERC issued an Order finding that the NYDEC exceeded the statutory time frame to take action under the Clean Water Act and, therefore, waived its opportunity to approve or deny the Water Quality Certification. FERC denied rehearing requests associated with its Order and FERC's decisions have been appealed and are pending in a separate action before the Second Circuit Court of Appeals. In addition, the Company commenced legal action in New York State Supreme Court challenging the NYDEC's actions with regard to various state permits. The Company remains committed to the project. In light of these pending legal actions and the need to complete necessary project development activities in advance of construction, the in-service date for the project is expected to be no earlier than fiscal 2022.

Other.  The Company is involved in other litigation and regulatory matters arising in the normal course of business.  These other matters may include, for example, negligence claims and tax, regulatory or other governmental audits, inspections, investigations and other proceedings.  These matters may involve state and federal taxes, safety, compliance with regulations, rate base, cost of service and purchased gas cost issues, among other things.  While these other matters arising in the normal course of business could have a material effect on earnings and cash flows in the period in which they are resolved, an estimate of the possible loss or range of loss, if any, cannot be made at this time.

Summary Of Significant Accounting Policies (Policy)

3 Months Ended

Dec. 31, 2019

Accounting Policies [Abstract]

Principles of Consolidation

Principles of Consolidation.  The Company consolidates all entities in which it has a controlling financial interest.  All significant intercompany balances and transactions are eliminated. The Company uses proportionate consolidation when accounting for drilling arrangements related to oil and gas producing properties accounted for under the full cost method of accounting.

The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period.  Actual results could differ from those estimates.

Earnings For Interim Periods

Earnings for Interim Periods.  The Company, in its opinion, has included all adjustments (which consist of only normally recurring adjustments, unless otherwise disclosed in this Form 10-Q) that are necessary for a fair statement of the results of operations for the reported periods. The consolidated financial statements and notes thereto, included herein, should be read in conjunction with the financial statements and notes for the years ended September 30, 2019, 2018 and 2017 that are included in the Company's 2019 Form 10-K.  The consolidated financial statements for the year ended September 30, 2020 will be audited by the Company's independent registered public accounting firm after the end of the fiscal year.

The earnings for the three months ended December 31, 2019 should not be taken as a prediction of earnings for the entire fiscal year ending September 30, 2020.  Most of the business of both the Utility segment and the Company's NFR operations (included in the All Other category) is seasonal in nature and is influenced by weather conditions.  Due to the seasonal nature of the heating business in the Utility segment and in the Company's NFR operations, earnings during the winter months normally represent a substantial part of the earnings that those businesses are expected to achieve for the entire fiscal year.  The Company’s business segments are discussed more fully in Note 9 — Business Segment Information.

Consolidated Statements of Cash Flows

Consolidated Statements of Cash Flows.  The components, as reported on the Company’s Consolidated Balance Sheets, of the total cash, cash equivalents, and restricted cash presented on the Statement of Cash Flows are as follows (in thousands):

	Three Months Ended   December 31, 2019				Three Months Ended   December 31, 2018
	Balance at October 1, 2019		Balance at December 31, 2019		Balance at October 1, 2018		Balance at December 31, 2018
Cash and Temporary Cash Investments	$	20,428	$	34,966	$	229,606	$	109,754
Hedging Collateral Deposits	6,832		9,666		3,441		2,784
Cash, Cash Equivalents, and Restricted Cash	$	27,260	$	44,632	$	233,047	$	112,538

The Company considers all highly liquid debt instruments purchased with a maturity date of generally three months or less to be cash equivalents. The Company’s restricted cash is composed entirely of amounts reported as Hedging Collateral Deposits on the Consolidated Balance Sheets. Hedging Collateral Deposits is an account title for cash held in margin accounts funded by the Company to serve as collateral for hedging positions. In accordance with its accounting policy, the Company does not offset hedging collateral deposits paid or received against related derivative financial instruments liability or asset balances.

Gas Stored Underground

Gas Stored Underground.  In the Utility segment, gas stored underground is carried at lower of cost or net realizable value, on a LIFO method.  Gas stored underground normally declines during the first and second quarters of the year and is replenished during the third and fourth quarters.  In the Utility segment, the current cost of replacing gas withdrawn from storage is recorded in the Consolidated Statements of Income and a reserve for gas replacement is recorded in the Consolidated Balance Sheets under the caption “Other Accruals and Current Liabilities.”  Such reserve, which amounted to $1.1 million at December 31, 2019, is reduced to zero by September 30 of each year as the inventory is replenished.

Property, Plant and Equipment

Property, Plant and Equipment.  In the Company’s Exploration and Production segment, oil and gas property acquisition, exploration and development costs are capitalized under the full cost method of accounting. Under this methodology, all costs associated with property acquisition, exploration and development activities are capitalized, including internal costs directly identified with acquisition, exploration and development activities. The internal costs that are capitalized do not include any costs

related to production, general corporate overhead, or similar activities. The Company does not recognize any gain or loss on the sale or other disposition of oil and gas properties unless the gain or loss would significantly alter the relationship between capitalized costs and proved reserves of oil and gas attributable to a cost center. The Company's capitalized costs relating to oil and gas producing activities, net of accumulated depreciation, depletion and amortization, were $1.7 billion at both December 31, 2019 and September 30, 2019.

Capitalized costs include costs related to unproved properties, which are excluded from amortization until proved reserves are found or it is determined that the unproved properties are impaired.  Such costs amounted to $57.9 million and $53.5 million at December 31, 2019 and September 30, 2019, respectively.  All costs related to unproved properties are reviewed quarterly to determine if impairment has occurred. The amount of any impairment is transferred to the pool of capitalized costs being amortized.

Capitalized costs are subject to the SEC full cost ceiling test. The ceiling test, which is performed each quarter, determines a limit, or ceiling, on the amount of property acquisition, exploration and development costs that can be capitalized. The ceiling under this test represents (a) the present value of estimated future net cash flows, excluding future cash outflows associated with settling asset retirement obligations that have been accrued on the balance sheet, using a discount factor of 10%, which is computed by applying prices of oil and gas (as adjusted for hedging) to estimated future production of proved oil and gas reserves as of the date of the latest balance sheet, less estimated future expenditures, plus (b) the cost of unevaluated properties not being depleted, less (c) income tax effects related to the differences between the book and tax basis of the properties. The gas and oil prices used to calculate the full cost ceiling are based on an unweighted arithmetic average of the first day of the month oil and gas prices for each month within the twelve-month period prior to the end of the reporting period. If capitalized costs, net of accumulated depreciation, depletion and amortization and related deferred income taxes, exceed the ceiling at the end of any quarter, a permanent impairment is required to be charged to earnings in that quarter.  At December 31, 2019, the ceiling exceeded the book value of the oil and gas properties by approximately $59.1 million. In adjusting estimated future cash flows for hedging under the ceiling test at December 31, 2019, estimated future net cash flows were increased by $9.1 million.

In August 2017, the FASB issued authoritative guidance which changes the financial reporting of hedging relationships to better portray the economic results of an entity's risk management activities and to simplify the application of hedge accounting.

The Company adopted this authoritative guidance effective October 1, 2019, recognizing a cumulative effect adjustment that decreased retained earnings by $1.0 million and increased accumulated other comprehensive income by the same amount.

In January 2016, the FASB issued authoritative guidance regarding the recognition and measurement of financial assets and liabilities. The authoritative guidance primarily affects the accounting for equity investments and the presentation and disclosure requirements for financial instruments. All equity investments in unconsolidated entities will be measured at fair value through earnings rather than through accumulated other comprehensive income. The Company adopted this authoritative guidance effective October 1, 2018 and, as called for by the modified retrospective method of adoption, recorded a cumulative effect adjustment during the quarter ended December 31, 2018 to increase retained earnings by $7.4 million and decrease accumulated other comprehensive income by the same amount.

Earnings Per Common Share

Earnings Per Common Share.  Basic earnings per common share is computed by dividing income or loss by the weighted average number of common shares outstanding for the period. Diluted earnings per common share reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock.  For purposes of determining earnings per common share, the potentially dilutive securities the Company had outstanding were SARs, restricted stock units and performance shares.  For the quarter ended December 31, 2019, the diluted weighted average shares outstanding shown on the Consolidated Statements of Income reflects the potential dilution as a result of these securities as determined using the Treasury Stock Method.  SARs, restricted stock units and performance shares that are antidilutive are excluded from the calculation of diluted earnings per common share. There were 733,617 securities and 318,106 securities excluded as being antidilutive for the quarter ended December 31, 2019 and December 31, 2018 respectively.

Stock-Based Compensation

Stock-Based Compensation.  The Company granted 254,608 performance shares during the quarter ended December 31, 2019. The weighted average fair value of such performance shares was $43.32 per share for the quarter ended December 31, 2019. Performance shares are an award constituting units denominated in common stock of the Company, the number of which may be adjusted over a performance cycle based upon the extent to which performance goals have been satisfied.  Earned performance shares may be distributed in the form of shares of common stock of the Company, an equivalent value in cash or a combination of cash and shares of common stock of the Company, as determined by the Company. The performance shares do not entitle the participant to receive dividends during the vesting period.

Half of the performance shares granted during the quarter ended December 31, 2019 must meet a performance goal related to relative return on capital over a three-year performance cycle.  The performance goal over the performance cycle is the Company’s total return on capital relative to the total return on capital of other companies in a group selected by the Compensation Committee (“Report Group”).  Total return on capital for a given company means the average of the Report Group companies’ returns on capital for each twelve month period corresponding to each of the Company’s fiscal years during the performance cycle, based on data reported for the Report Group companies in the Bloomberg database.  The number of these performance shares that will vest and be paid will depend upon the Company’s performance relative to the Report Group and not upon the absolute level of return achieved by the Company.  The fair value of these performance shares is calculated by multiplying the expected number of shares that will be issued by the average market price of Company common stock on the date of grant reduced by the present value of forgone dividends over the vesting term of the award.  The fair value is recorded as compensation expense over the vesting term of the award.  The other half of the performance shares granted during the quarter ended December 31, 2019 must meet a performance goal related to relative total shareholder return over a three-year performance cycle.  The performance goal over the performance cycle is the Company’s three-year total shareholder return relative to the three-year total shareholder return of the other companies in the Report Group.  Three-year total shareholder return for a given company will be based on the data reported for that company (with the starting and ending stock prices over the performance cycle calculated as the average closing stock price for the prior calendar month and with dividends reinvested in that company’s securities at each ex-dividend date) in the Bloomberg database.  The number of these total shareholder return performance shares ("TSR performance shares") that will vest and be paid will depend upon the Company’s performance relative to the Report Group and not upon the absolute level of return achieved by the Company.  The fair value price at the date of grant for the TSR performance shares is determined using a Monte Carlo simulation technique, which includes a reduction in value for the present value of forgone dividends over the vesting term of the award.  This price is multiplied by the number of TSR performance shares awarded, the result of which is recorded as compensation expense over the vesting term of the award.

The Company granted 150,839 nonperformance-based restricted stock units during the quarter ended December 31, 2019.  The weighted average fair value of such nonperformance-based restricted stock units was $40.38 per share for the quarter ended December 31, 2019.  Restricted stock units represent the right to receive shares of common stock of the Company (or the

equivalent value in cash or a combination of cash and shares of common stock of the Company, as determined by the Company) at the end of a specified time period. These nonperformance-based restricted stock units do not entitle the participant to receive dividends during the vesting period. The accounting for nonperformance-based restricted stock units is the same as the accounting for restricted share awards, except that the fair value at the date of grant of the restricted stock units must be reduced by the present value of forgone dividends over the vesting term of the award.

Fair Value Disclosures [Abstract]

Schedule of Fair Value, Assets and Liabilities Measured on Recurring Basis

The following table sets forth, by level within the fair value hierarchy, the Company's financial assets and liabilities (as applicable) that were accounted for at fair value on a recurring basis as of December 31, 2019 and September 30, 2019.  Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The fair value presentation for over the counter swaps combines gas and oil swaps because a significant number of the counterparties enter into both gas and oil swap agreements with the Company.

Accounting Policies [Abstract]

Summary Of Significant Accounting Policies

Summary of Significant Accounting Policies

Principles of Consolidation.  The Company consolidates all entities in which it has a controlling financial interest.  All significant intercompany balances and transactions are eliminated. The Company uses proportionate consolidation when accounting for drilling arrangements related to oil and gas producing properties accounted for under the full cost method of accounting.

The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period.  Actual results could differ from those estimates.

Earnings for Interim Periods.  The Company, in its opinion, has included all adjustments (which consist of only normally recurring adjustments, unless otherwise disclosed in this Form 10-Q) that are necessary for a fair statement of the results of operations for the reported periods. The consolidated financial statements and notes thereto, included herein, should be read in conjunction with the financial statements and notes for the years ended September 30, 2019, 2018 and 2017 that are included in the Company's 2019 Form 10-K.  The consolidated financial statements for the year ended September 30, 2020 will be audited by the Company's independent registered public accounting firm after the end of the fiscal year.

The earnings for the three months ended December 31, 2019 should not be taken as a prediction of earnings for the entire fiscal year ending September 30, 2020.  Most of the business of both the Utility segment and the Company's NFR operations (included in the All Other category) is seasonal in nature and is influenced by weather conditions.  Due to the seasonal nature of the heating business in the Utility segment and in the Company's NFR operations, earnings during the winter months normally represent a substantial part of the earnings that those businesses are expected to achieve for the entire fiscal year.  The Company’s business segments are discussed more fully in Note 9 — Business Segment Information.

Consolidated Statements of Cash Flows.  The components, as reported on the Company’s Consolidated Balance Sheets, of the total cash, cash equivalents, and restricted cash presented on the Statement of Cash Flows are as follows (in thousands):

	Three Months Ended   December 31, 2019				Three Months Ended   December 31, 2018
	Balance at October 1, 2019		Balance at December 31, 2019		Balance at October 1, 2018		Balance at December 31, 2018
Cash and Temporary Cash Investments	$	20,428	$	34,966	$	229,606	$	109,754
Hedging Collateral Deposits	6,832		9,666		3,441		2,784
Cash, Cash Equivalents, and Restricted Cash	$	27,260	$	44,632	$	233,047	$	112,538

The Company considers all highly liquid debt instruments purchased with a maturity date of generally three months or less to be cash equivalents. The Company’s restricted cash is composed entirely of amounts reported as Hedging Collateral Deposits on the Consolidated Balance Sheets. Hedging Collateral Deposits is an account title for cash held in margin accounts funded by the Company to serve as collateral for hedging positions. In accordance with its accounting policy, the Company does not offset hedging collateral deposits paid or received against related derivative financial instruments liability or asset balances.

Gas Stored Underground.  In the Utility segment, gas stored underground is carried at lower of cost or net realizable value, on a LIFO method.  Gas stored underground normally declines during the first and second quarters of the year and is replenished during the third and fourth quarters.  In the Utility segment, the current cost of replacing gas withdrawn from storage is recorded in the Consolidated Statements of Income and a reserve for gas replacement is recorded in the Consolidated Balance Sheets under the caption “Other Accruals and Current Liabilities.”  Such reserve, which amounted to $1.1 million at December 31, 2019, is reduced to zero by September 30 of each year as the inventory is replenished.

Property, Plant and Equipment.  In the Company’s Exploration and Production segment, oil and gas property acquisition, exploration and development costs are capitalized under the full cost method of accounting. Under this methodology, all costs associated with property acquisition, exploration and development activities are capitalized, including internal costs directly identified with acquisition, exploration and development activities. The internal costs that are capitalized do not include any costs

related to production, general corporate overhead, or similar activities. The Company does not recognize any gain or loss on the sale or other disposition of oil and gas properties unless the gain or loss would significantly alter the relationship between capitalized costs and proved reserves of oil and gas attributable to a cost center. The Company's capitalized costs relating to oil and gas producing activities, net of accumulated depreciation, depletion and amortization, were $1.7 billion at both December 31, 2019 and September 30, 2019.

Capitalized costs include costs related to unproved properties, which are excluded from amortization until proved reserves are found or it is determined that the unproved properties are impaired.  Such costs amounted to $57.9 million and $53.5 million at December 31, 2019 and September 30, 2019, respectively.  All costs related to unproved properties are reviewed quarterly to determine if impairment has occurred. The amount of any impairment is transferred to the pool of capitalized costs being amortized.

Capitalized costs are subject to the SEC full cost ceiling test. The ceiling test, which is performed each quarter, determines a limit, or ceiling, on the amount of property acquisition, exploration and development costs that can be capitalized. The ceiling under this test represents (a) the present value of estimated future net cash flows, excluding future cash outflows associated with settling asset retirement obligations that have been accrued on the balance sheet, using a discount factor of 10%, which is computed by applying prices of oil and gas (as adjusted for hedging) to estimated future production of proved oil and gas reserves as of the date of the latest balance sheet, less estimated future expenditures, plus (b) the cost of unevaluated properties not being depleted, less (c) income tax effects related to the differences between the book and tax basis of the properties. The gas and oil prices used to calculate the full cost ceiling are based on an unweighted arithmetic average of the first day of the month oil and gas prices for each month within the twelve-month period prior to the end of the reporting period. If capitalized costs, net of accumulated depreciation, depletion and amortization and related deferred income taxes, exceed the ceiling at the end of any quarter, a permanent impairment is required to be charged to earnings in that quarter.  At December 31, 2019, the ceiling exceeded the book value of the oil and gas properties by approximately $59.1 million. In adjusting estimated future cash flows for hedging under the ceiling test at December 31, 2019, estimated future net cash flows were increased by $9.1 million.

In August 2017, the FASB issued authoritative guidance which changes the financial reporting of hedging relationships to better portray the economic results of an entity's risk management activities and to simplify the application of hedge accounting.

The Company adopted this authoritative guidance effective October 1, 2019, recognizing a cumulative effect adjustment that decreased retained earnings by $1.0 million and increased accumulated other comprehensive income by the same amount.

In January 2016, the FASB issued authoritative guidance regarding the recognition and measurement of financial assets and liabilities. The authoritative guidance primarily affects the accounting for equity investments and the presentation and disclosure requirements for financial instruments. All equity investments in unconsolidated entities will be measured at fair value through earnings rather than through accumulated other comprehensive income. The Company adopted this authoritative guidance effective October 1, 2018 and, as called for by the modified retrospective method of adoption, recorded a cumulative effect adjustment during the quarter ended December 31, 2018 to increase retained earnings by $7.4 million and decrease accumulated other comprehensive income by the same amount.

Earnings Per Common Share.  Basic earnings per common share is computed by dividing income or loss by the weighted average number of common shares outstanding for the period. Diluted earnings per common share reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock.  For purposes of determining earnings per common share, the potentially dilutive securities the Company had outstanding were SARs, restricted stock units and performance shares.  For the quarter ended December 31, 2019, the diluted weighted average shares outstanding shown on the Consolidated Statements of Income reflects the potential dilution as a result of these securities as determined using the Treasury Stock Method.  SARs, restricted stock units and performance shares that are antidilutive are excluded from the calculation of diluted earnings per common share. There were 733,617 securities and 318,106 securities excluded as being antidilutive for the quarter ended December 31, 2019 and December 31, 2018 respectively.

Stock-Based Compensation.  The Company granted 254,608 performance shares during the quarter ended December 31, 2019. The weighted average fair value of such performance shares was $43.32 per share for the quarter ended December 31, 2019. Performance shares are an award constituting units denominated in common stock of the Company, the number of which may be adjusted over a performance cycle based upon the extent to which performance goals have been satisfied.  Earned performance shares may be distributed in the form of shares of common stock of the Company, an equivalent value in cash or a combination of cash and shares of common stock of the Company, as determined by the Company. The performance shares do not entitle the participant to receive dividends during the vesting period.

Half of the performance shares granted during the quarter ended December 31, 2019 must meet a performance goal related to relative return on capital over a three-year performance cycle.  The performance goal over the performance cycle is the Company’s total return on capital relative to the total return on capital of other companies in a group selected by the Compensation Committee (“Report Group”).  Total return on capital for a given company means the average of the Report Group companies’ returns on capital for each twelve month period corresponding to each of the Company’s fiscal years during the performance cycle, based on data reported for the Report Group companies in the Bloomberg database.  The number of these performance shares that will vest and be paid will depend upon the Company’s performance relative to the Report Group and not upon the absolute level of return achieved by the Company.  The fair value of these performance shares is calculated by multiplying the expected number of shares that will be issued by the average market price of Company common stock on the date of grant reduced by the present value of forgone dividends over the vesting term of the award.  The fair value is recorded as compensation expense over the vesting term of the award.  The other half of the performance shares granted during the quarter ended December 31, 2019 must meet a performance goal related to relative total shareholder return over a three-year performance cycle.  The performance goal over the performance cycle is the Company’s three-year total shareholder return relative to the three-year total shareholder return of the other companies in the Report Group.  Three-year total shareholder return for a given company will be based on the data reported for that company (with the starting and ending stock prices over the performance cycle calculated as the average closing stock price for the prior calendar month and with dividends reinvested in that company’s securities at each ex-dividend date) in the Bloomberg database.  The number of these total shareholder return performance shares ("TSR performance shares") that will vest and be paid will depend upon the Company’s performance relative to the Report Group and not upon the absolute level of return achieved by the Company.  The fair value price at the date of grant for the TSR performance shares is determined using a Monte Carlo simulation technique, which includes a reduction in value for the present value of forgone dividends over the vesting term of the award.  This price is multiplied by the number of TSR performance shares awarded, the result of which is recorded as compensation expense over the vesting term of the award.

The Company granted 150,839 nonperformance-based restricted stock units during the quarter ended December 31, 2019.  The weighted average fair value of such nonperformance-based restricted stock units was $40.38 per share for the quarter ended December 31, 2019.  Restricted stock units represent the right to receive shares of common stock of the Company (or the

equivalent value in cash or a combination of cash and shares of common stock of the Company, as determined by the Company) at the end of a specified time period. These nonperformance-based restricted stock units do not entitle the participant to receive dividends during the vesting period. The accounting for nonperformance-based restricted stock units is the same as the accounting for restricted share awards, except that the fair value at the date of grant of the restricted stock units must be reduced by the present value of forgone dividends over the vesting term of the award.

Financial Instruments

Financial Instruments, Owned, at Fair Value [Abstract]

Financial Instruments

Financial Instruments

Long-Term Debt.  The fair market value of the Company’s debt, as presented in the table below, was determined using a discounted cash flow model, which incorporates the Company’s credit ratings and current market conditions in determining the yield, and subsequently, the fair market value of the debt.  Based on these criteria, the fair market value of long-term debt, including current portion, was as follows (in thousands): 

	December 31, 2019				September 30, 2019
	Carrying Amount		Fair Value		Carrying Amount		Fair Value
Long-Term Debt	$	2,134,339	$	2,253,232	$	2,133,718	$	2,257,085

The fair value amounts are not intended to reflect principal amounts that the Company will ultimately be required to pay. Carrying amounts for other financial instruments recorded on the Company’s Consolidated Balance Sheets approximate fair value. The fair value of long-term debt was calculated using observable inputs (U.S. Treasuries/LIBOR for the risk free component and company specific credit spread information – generally obtained from recent trade activity in the debt).  As such, the Company considers the debt to be Level 2.

Any temporary cash investments, notes payable to banks and commercial paper are stated at cost. Temporary cash investments are considered Level 1, while notes payable to banks and commercial paper are considered to be Level 2.  Given the short-term nature of the notes payable to banks and commercial paper, the Company believes cost is a reasonable approximation of fair value.

Other Investments. The components of the Company's Other Investments are as follows (in thousands):

	At December 31, 2019		At September 30, 2019
Life Insurance Contracts	$	41,336	$	41,074
Equity Mutual Fund	36,740		40,660
Fixed Income Mutual Fund	62,220		62,339
Marketable Equity Securities	933		844
	$	141,229	$	144,917

Investments in life insurance contracts are stated at their cash surrender values or net present value. Investments in an equity mutual fund, a fixed income mutual fund and the stock of an insurance company (marketable equity securities) are stated at fair value based on quoted market prices with changes in fair value recognized in net income. The insurance contracts and marketable equity and fixed income securities are primarily informal funding mechanisms for various benefit obligations the Company has to certain employees.

Derivative Financial Instruments.  The Company uses derivative financial instruments to manage commodity price risk in the Exploration and Production segment as well as by NFR (included in the All Other category). The Company enters into futures contracts and over-the-counter swap agreements for natural gas and crude oil to manage the price risk associated with forecasted sales of gas and oil. In addition, the Company also enters into foreign exchange forward contracts to manage the risk of currency fluctuations associated with transportation costs denominated in Canadian currency in the Exploration and Production segment. These instruments are accounted for as cash flow hedges. The Company also enters into futures contracts and swaps, which are accounted for as cash flow hedges, to manage the price risk associated with forecasted gas purchases. The Company enters into futures contracts and swaps to mitigate risk associated with fixed price sales commitments, fixed price purchase commitments, and the decline in value of natural gas held in storage. These instruments are accounted for as fair value hedges. The duration of the Company’s combined cash flow and fair value commodity hedges does not typically exceed 5 years while the foreign currency forward contracts do not exceed 7 years. The Exploration and Production segment holds the majority of the Company’s derivative financial instruments.

The Company has presented its net derivative assets and liabilities as “Fair Value of Derivative Financial Instruments” on its Consolidated Balance Sheets at December 31, 2019 and September 30, 2019.  Substantially all of the derivative financial instruments reported on those line items relate to commodity contracts and a small portion relates to foreign currency forward contracts.

Cash Flow Hedges

For derivative instruments that are designated and qualify as a cash flow hedge, the gain or loss on the derivative is reported as a component of other comprehensive income (loss) and reclassified into earnings in the period or periods during which the hedged transaction affects earnings. Prior to October 1, 2019, gains and losses on the derivative representing either hedge ineffectiveness or hedge components excluded from the the assessment of effectiveness were recognized in current earnings rather than as a component of other comprehensive income (loss). During the quarter ended December 31, 2018, the Company recorded a $6.5 million hedging ineffectiveness gain that impacted operating revenue. With the October 1, 2019 adoption of the authoritative guidance that changes the financial reporting of hedging relationships and simplifies the application of hedge accounting, derivative instruments that are designated and qualify as a cash flow hedge will no longer have hedge ineffectiveness or a component excluded from the assessment of the effectiveness.

As of December 31, 2019, the Company had the following commodity derivative contracts (swaps and futures contracts) outstanding:

Commodity	Units
Natural Gas	88.1	Bcf (short positions)
Natural Gas	2.7	Bcf (long positions)
Crude Oil	2,376,000	Bbls (short positions)

    

As of December 31, 2019, the Company was hedging a total of $77.3 million of forecasted transportation costs denominated in Canadian dollars with foreign currency forward contracts (long positions).

As of December 31, 2019, the Company had $41.8 million ($30.7 million after tax) of net hedging gains included in the accumulated other comprehensive income (loss) balance. It is expected that $39.1 million ($28.7 million after tax) of unrealized gains will be reclassified into the Consolidated Statement of Income within the next 12 months as the underlying hedged transactions are recorded in earnings.

Total	$	495		$	44,518			$	7,352		$	(20,517	)

Fair Value Hedges

The Company utilizes fair value hedges to mitigate risk associated with fixed price sales commitments, fixed price purchase commitments and the decline in the value of certain natural gas held in storage. With respect to fixed price sales commitments, the Company enters into long positions to mitigate the risk of price increases for natural gas supplies that could occur after the Company enters into fixed price sales agreements with its customers. With respect to fixed price purchase commitments, the Company enters into short positions to mitigate the risk of price decreases that could occur after the Company locks into fixed price purchase deals with its suppliers. With respect to storage hedges, the Company enters into short positions to mitigate the risk of price decreases that could result in a lower of cost or net realizable value writedown of the value of natural gas in storage that is recorded in the Company’s financial statements. As of December 31, 2019, NFR had fair value hedges covering approximately 23.5 Bcf (23.3 Bcf of fixed price sales commitments and 0.2 Bcf of commitments related to the withdrawal of storage gas). For derivative instruments that are designated and qualify as a fair value hedge, the gain or loss on the derivative as well as the offsetting gain or loss on the hedged item attributable to the hedged risk completely offset each other in current earnings, as shown below.

Credit Risk

The Company may be exposed to credit risk on any of the derivative financial instruments that are in a gain position. Credit risk relates to the risk of loss that the Company would incur as a result of nonperformance by counterparties pursuant to the terms of their contractual obligations. To mitigate such credit risk, management performs a credit check, and then on a quarterly basis monitors counterparty credit exposure. The majority of the Company’s counterparties are financial institutions and energy traders. The Company has over-the-counter swap positions and applicable foreign currency forward contracts with fourteen counterparties of which twelve are in a net gain position. On average, the Company had $3.4 million of credit exposure per counterparty in a gain position at December 31, 2019. The maximum credit exposure per counterparty in a gain position at

December 31, 2019 was $6.9 million. As of December 31, 2019, no collateral was received from the counterparties by the Company. The Company's gain position on such derivative financial instruments had not exceeded the established thresholds at which the counterparties would be required to post collateral, nor had the counterparties' credit ratings declined to levels at which the counterparties were required to post collateral.

As of December 31, 2019, eleven of the fourteen counterparties to the Company’s outstanding derivative instrument contracts (specifically the over-the-counter swaps and applicable foreign currency forward contracts) had a common credit-risk related contingency feature. In the event the Company’s credit rating increases or falls below a certain threshold (applicable debt ratings), the available credit extended to the Company would either increase or decrease. A decline in the Company’s credit rating, in and of itself, would not cause the Company to be required to increase the level of its hedging collateral deposits (in the form of cash deposits, letters of credit or treasury debt instruments). If the Company’s outstanding derivative instrument contracts were in a liability position (or if the liability were larger) and/or the Company’s credit rating declined, then additional hedging collateral deposits may be required.  At December 31, 2019, the fair market value of the derivative financial instrument assets with a credit-risk related contingency feature was $31.3 million according to the Company’s internal model (discussed in Note 4 — Fair Value Measurements).  At December 31, 2019, the fair market value of the derivative financial instrument liabilities with a credit-risk related contingency feature was $0.6 million according to the Company's internal model. For its over-the-counter swap agreements and foreign currency forward contracts, no hedging collateral deposits were required to be posted by the Company at December 31, 2019.

For its exchange traded futures contracts, the Company was required to post $9.7 million in hedging collateral deposits as of December 31, 2019. As these are exchange traded futures contracts, there are no specific credit-risk related contingency features. The Company posts or receives hedging collateral based on open positions and margin requirements it has with its counterparties.

The Company’s requirement to post hedging collateral deposits and the Company's right to receive hedging collateral deposits is based on the fair value determined by the Company’s counterparties, which may differ from the Company’s assessment of fair value. Hedging collateral deposits may also include closed derivative positions in which the broker has not cleared the cash from the account to offset the derivative liability. The Company records liabilities related to closed derivative positions in Other Accruals and Current Liabilities on the Consolidated Balance Sheet. These liabilities are relieved when the broker clears the cash from the hedging collateral deposit account.

Segment Reporting [Abstract]

Business Segment Information

Business Segment Information    

The Company reports financial results for four segments: Exploration and Production, Pipeline and Storage, Gathering and Utility.  The division of the Company’s operations into reportable segments is based upon a combination of factors including differences in products and services, regulatory environment and geographic factors. As reported in the Company's 2019 Form 10-K, the Company previously reported financial results for five business segments: Exploration and Production, Pipeline and Storage, Gathering, Utility and Energy Marketing. However, management made the decision to eliminate the Energy Marketing segment as a reportable segment based on the fact that the energy marketing operations do not meet any of the quantitative thresholds specified by authoritative guidance related to segment reporting. Furthermore, from a qualitative standpoint, management’s focus has changed regarding the energy marketing operations, and management no longer considers the energy marketing operations to be integral to the overall operations of the Company. As a result of this change in focus and the fact that the energy marketing operations cannot be aggregated into one of the other four reportable business segments, the energy marketing operations have been included in the All Other category in the disclosures that follow. Prior year segment information shown below has been restated to reflect this change in presentation.

The data presented in the tables below reflect financial information for the segments and reconciliations to consolidated amounts.  As stated in the 2019 Form 10-K, the Company evaluates segment performance based on income before discontinued operations (when applicable).  When this is not applicable, the Company evaluates performance based on net income.  There have not been any changes in the basis of segmentation nor in the basis of measuring segment profit or loss from those used in the Company’s 2019 Form 10-K.  A listing of segment assets at December 31, 2019 and September 30, 2019 is shown in the tables below.

Revenue from Contract with Customer [Abstract]

Revenue from Contracts with Customers

Revenue from Contracts with Customers

The Company adopted authoritative guidance regarding revenue recognition on October 1, 2018 using the modified retrospective method of adoption for open contracts as of October 1, 2018. A cumulative effect adjustment to retained earnings was not necessary since no revenue recognition differences were identified when comparing the revenue recognition criteria under the new authoritative guidance to the previous guidance. The Company records revenue related to its derivative financial instruments in the Exploration and Production segment as well as in its NFR operations (included in the All Other category). The Company also records revenue related to alternative revenue programs in its Utility segment. Revenue related to derivative financial instruments and alternative revenue programs are excluded from the scope of the new authoritative guidance since they are accounted for under other existing accounting guidance.

The following tables provide a disaggregation of the Company's revenues for the three months ended December 31, 2019 and 2018, presented by type of service from each reportable segment. As reported in the Company's 2019 Form 10-K, the Company's NFR operations were previously reported as the Energy Marketing segment, however the Company is no longer reporting the energy marketing operations as a separate reportable segment. Prior year disaggregation of revenue information shown below has been restated to reflect this change in presentation.

New York Jurisdiction

Distribution Corporation's current delivery rates in its New York jurisdiction were approved by the NYPSC in an order issued on April 20, 2017 with rates becoming effective May 1, 2017. The order provided for a return on equity of 8.7%. The order also directed the implementation of an earnings sharing mechanism to be in place beginning on April 1, 2018.

Pennsylvania Jurisdiction

Distribution Corporation’s Pennsylvania jurisdiction delivery rates are being charged to customers in accordance with a rate settlement approved by the PaPUC. The rate settlement does not specify any requirement to file a future rate case.

FERC Jurisdiction

Supply Corporation filed a Section 4 rate case on July 31, 2019 proposing rate increases to be effective September 1, 2019. The proposed rates reflect an annual cost of service of $295.4 million, a rate base of $970.8 million and a proposed cost of equity of 15%. The FERC has accepted the filed rates and suspended the effective date of the increases until February 1, 2020, when the rates will be made effective, subject to refund. If the rates finally approved at the end of the proceeding exceed the rates that were in effect at July 31, 2019, but are less than rates put into effect subject to refund on February 1, 2020, Supply Corporation would be required to refund the difference between the rates collected subject to refund and the final approved rates, with interest at the FERC-approved rate. If the rates approved at the end of the proceeding are lower than the rates in effect at July 31, 2019, such lower rates will become effective prospectively from the date of the applicable FERC order, and refunds with interest will be limited to the difference between the rates collected subject to refund and the rates in effect at July 31, 2019.

Empire's 2019 rate settlement requires a Section 4 rate case filing no later than May 1, 2025. Empire has no rate case currently on file.

Income Taxes

Income Taxes

The effective tax rates for the quarters ended December 31, 2019 and December 31, 2018 were 26.6% and 18.2%, respectively. The increase in the effective tax rate was primarily the result of the reversal of a $5.0 million valuation allowance in fiscal 2019 related to sequestration of AMT credit refunds discussed below, differences between the book and tax treatment of stock compensation, as well as the elimination of the Enhanced Oil Recovery tax credit in fiscal 2020.

The 2017 Tax Reform Act repealed the corporate alternative minimum tax (AMT) and provides that the Company’s existing AMT credit carryovers are refundable, if not utilized to reduce tax, beginning in fiscal 2019. As of September 30, 2018, the Company had $85.0 million of AMT credit carryovers that are expected to be refunded between fiscal 2020 and fiscal 2023, if not previously utilized. During fiscal 2018, the Department of Treasury indicated that a portion of the refundable AMT credit carryovers would be subject to sequestration. Accordingly, the Company recorded a $5.0 million valuation allowance related to this sequestration in fiscal 2018. During the quarter ended December 31, 2018, the Office of Management and Budget determined that these AMT refunds would not be subject to sequestration. As such, the Company removed the valuation allowance. These amounts are recorded in Deferred Income Taxes and will be reclassified to a receivable when the amounts are expected to be realized in cash. The Company reclassified AMT credit refunds of $21.3 million and $42.1 million from Deferred Income Taxes to Other Assets at December 31, 2019 and 2018, respectively. The Company received $42.5 million of AMT credit refunds related to fiscal 2019 in January 2020.

The SEC issued guidance in Staff Accounting Bulletin 118 (SAB 118) which provides for up to a one year period (the measurement period) in which to complete the required analysis and income tax accounting for the 2017 Tax Reform Act. Based upon the available guidance, the Company completed the remeasurement of deferred income taxes as of December 31, 2018. Any subsequent guidance or clarification related to the 2017 Tax Reform Act will be accounted for in the period that the guidance is issued.

Leases

Leases [Abstract]

Leases

Leases

On October 1, 2019, the Company adopted authoritative guidance regarding lease accounting, which requires entities that lease the use of property, plant and equipment to recognize on the balance sheet the assets and liabilities for the rights and obligations created by all leases, including leases classified as operating leases. The Company implemented the new standard using the optional transition method and elected to apply the following practical expedients provided in the authoritative guidance:

1. For contracts that commenced prior to and existed as of October 1, 2019, a package of practical expedients to not reassess whether a contract is or contains a lease, lease classification, and initial direct costs under the new authoritative guidance;

2. An election not to apply the recognition requirements in the new authoritative guidance to short-term leases (a lease that at commencement date has a lease term of one year or less);

3. A practical expedient to not reassess certain land easements that existed prior to October 1, 2019 and were not previously accounted for as leases under the prior authoritative guidance; and

4. A practical expedient that permits combining lease and non-lease components in a contract and accounting for the combination as a lease (elected by asset-class).

Upon adoption, the Company increased assets and liabilities on its Consolidated Balance Sheet by $19.7 million. The adoption did not result in a cumulative effect adjustment to earnings reinvested in the business or have a material impact on the Company’s Consolidated Statement of Income or Consolidated Statement of Cash Flows. Comparative periods, including disclosures relating to those periods, were not restated.

Nature of Leases

The Company primarily leases building space and drilling rigs, and on a limited basis compressor equipment and other miscellaneous assets. The Company determines if an arrangement is a lease at the inception of the arrangement. To the extent that an arrangement represents a lease, the Company classifies that lease as an operating or a finance lease in accordance with the authoritative guidance. As of December 31, 2019, the Company did not have any finance leases. Aside from a sublease of office space at the Company’s corporate headquarters, the Company does not have any material arrangements where the Company is the lessor.

Buildings and Property

The Company enters into building and property rental agreements with third parties for office space, certain field locations and other properties used in the Company’s operations. Building and property leases include the Company’s corporate headquarters in Williamsville, New York, and Exploration and Production segment offices in Houston, Texas, and Pittsburgh, Pennsylvania. The primary non-cancelable terms of the Company’s building and property leases range from six months to eleven years. Most building leases include one or more options to renew, generally at the Company’s sole discretion, with renewal terms that can extend the lease terms from one year to fourteen years. Renewal options are included in the lease term if they are reasonably certain to be exercised. The agreements do not contain any material restrictive covenants.

Drilling Rigs

The Company enters into contracts for drilling rig services with third party contractors to support Seneca’s development activities in Pennsylvania and California. Seneca’s drilling rig arrangements are structured with a non-cancelable primary term of one year or less. Upon mutual agreement with the contractor, Seneca has the option to extend the contract with amended terms and conditions, including a renegotiated day rate fee.

The Company has strategically entered into shorter-term drilling rig arrangements to allow for operational and financial flexibility to respond to changes in its operating and economic environment. The Company uses discretion in choosing to extend or not extend drilling rig contracts on a rig by rig basis depending on market and operating conditions present at the time the contract expires, including prices for natural gas and oil.

Due to these considerations, the Company concluded that it is not reasonably certain that it will elect to extend any of its drilling rig arrangements beyond their primary non-cancelable terms of one year or less. Consequently, the Company’s drilling rig leases are deemed to be short-term leases subject to the exemption for balance sheet recognition. These costs are capitalized as part of oil and natural gas properties on the Consolidated Balance Sheet when incurred.

Significant Judgments

Lease Identification

The Company uses judgment when determining whether or not an arrangement is or contains a lease. A contract is or contains a lease if the contract conveys the right to use an explicitly or implicitly identified asset that is physically distinct and the Company has the right to control the use of the identified asset for a period of time. When determining right of control, the Company evaluates whether it directs the use of the asset and obtains substantially all of the economic benefits from the use of the asset.

Discount Rate

The Company uses a discount rate to calculate the present value of lease payments in order to determine lease classification and measurement of the lease asset and liability. In the absence of a rate of interest that is readily determinable in the contract, the Company estimates the incremental borrowing rate (IBR) for each lease. The IBR reflects the rate of interest that the Company would pay on the lease commencement date to borrow an amount equal to the lease payments on a collateralized basis over a similar term in similar economic environments.

Firm Transportation and Storage Contracts

The Company’s subsidiaries enter into long-term arrangements to both reserve firm transportation capacity on third party pipelines and provide firm transportation and storage services to third party shippers. The Company’s firm capacity contracts with non-affiliated entities do not provide rights to use substantially all of the underlying pipeline or storage asset. As such, the Company has concluded that these arrangements are not leases under the authoritative guidance.

Oil and Gas Leases

The new authoritative guidance does not apply to leases to explore for or use minerals, oil or natural gas resources, including the right to explore for those natural resources and rights to use the land in which those natural resources are contained. As such, the Company has concluded that its oil and gas exploration and production leases and gas storage leases are not leases under the authoritative guidance.

Amounts Recognized in the Financial Statements

Operating lease costs, excluding those relating to short-term drilling rig leases that are capitalized as part of oil and natural gas properties under full cost pool accounting, are presented in Operations and Maintenance expense on the Consolidated Statement of Income. The following table summarizes the components of the Company’s total operating lease costs (in thousands):

	Three Months Ended   December 31, 2019
Operating Lease Expense	$	974
Variable Lease Expense (1)	134
Short-Term Lease Expense (2)	64
Sublease Income	(80		)
Total Lease Expense	$	1,092
Short-Term Lease Costs Recorded to Property, Plant and Equipment (3)	$	7,512

⁽¹⁾  Variable lease payments that are not dependent on an index or rate are not included in the lease liability.

⁽²⁾  Short-term lease costs exclude expenses related to leases with a lease term of one month or less.

⁽³⁾  Short-term lease costs relating to drilling rig leases that are capitalized as part of oil and natural gas properties under full cost pool accounting.

Right-of-use assets and lease liabilities are recognized at the commencement date of a leasing arrangement based on the present value of lease payments over the lease term. As of December 31, 2019, the weighted average remaining lease term was 8.7 years and the weighted average discount rate was 3.49%.

The Company’s right-of-use operating lease assets are reflected as Deferred Charges on the Consolidated Balance Sheet. The corresponding operating lease liabilities are reflected in Other Accruals and Current Liabilities (current) and Other Deferred Credits (noncurrent). Short-term leases that have a lease term of one year or less are not recorded on the Consolidated Balance Sheet.

The following amounts related to operating leases were recorded on the Company’s Consolidated Balance Sheet (in thousands):

	At December 31, 2019
Assets:
Deferred Charges	$	18,940
Liabilities:
Other Accruals and Current Liabilities	$	3,298
Other Deferred Credits	$	15,434

For the three months ended December 31, 2019, cash paid for operating liabilities, and reported in cash flows provided by operating activities on the Company’s Consolidated Statement of Cash Flows, was $1.1 million. During the three months ended December 31, 2019, the Company did not record any right-of-use assets in exchange for new lease liabilities.

The following schedule of operating lease liability maturities summarizes the undiscounted lease payments owed by the Company to lessors pursuant to contractual agreements in effect as of December 31, 2019 (in thousands):

	At December 31, 2019
2020 (remaining 9 months)	$	2,575
2021	2,813
2022	2,264
2023	2,270
2024	2,237
Thereafter	9,717
Total Lease Payments	21,876
Less: Interest	(3,144		)
Total Lease Liability	$	18,732

The future minimum operating lease payments as of September 30, 2019, as reported in the Company's 2019 Form 10-K, under the prior authoritative guidance are as follows (in thousands):

	At September 30, 2019
2020 (1)	$	12,356
2021	2,813
2022	2,264
2023	2,270
2024	2,237
Thereafter	9,717
Total Operating Lease Obligations	$	31,657

⁽¹⁾ 

The future minimum operating lease payment amount for 2020 includes short-term leases, including drilling rigs, that are not included in the schedule of operating lease liability maturities above under the new authoritative guidance.
