Deferred Contract Costs

We recognize an asset for incremental commission expenses paid to sales personnel in conjunction with obtaining new residential customer product and equipment maintenance service contracts. We defer these costs only when we have determined the commissions are, in fact, incremental and would not have been incurred absent the customer contract. Costs to obtain a contract are amortized and recorded ratably as delivery and branch expenses over the period representing the transfer of goods or services to which the assets relate. Costs to obtain new residential product and equipment maintenance service contracts are amortized as expense over the estimated customer relationship period of approximately five years. Deferred contract costs are classified as current or non-current within “Prepaid expenses and other current assets” and “Deferred charges and other assets, net,” respectively. At June 30, 2022, the amount of deferred contract costs included in “Prepaid expenses and other current assets” and “Deferred charges and other assets, net” was $3.4 million and $5.7 million, respectively. At September 30, 2021, the amount of deferred contract costs included in “Prepaid expenses and other current assets” and “Deferred charges and other assets, net” was $3.4 million and $5.7 million, respectively. For the nine months ended June 30, 2022 and June 30, 2021 we recognized expense of $3.0 million and $2.9 million, respectively, associated with the amortization of deferred contract costs within “Delivery and branch expenses” in the Condensed Consolidated Statement of Operations.

Contract Liability Balances

The Company has contract liabilities for advanced payments received from customers for future oil deliveries (primarily amounts received from customers on “smart pay” budget payment plans in advance of oil deliveries) and obligations to service

customers with equipment maintenance service contracts. Contract liabilities are recognized straight-line over the service contract period, generally one year or less. As of June 30, 2022 and September 30, 2021 the Company had contract liabilities of $105.0 million and $141.6 million, respectively. During the nine months ended June 30, 2022, the Company recognized $123.8 million of revenue that was included in the September 30, 2021 contract liability balance. During the nine months ended June 30, 2021 the Company recognized $122.2 million of revenue that was included in the September 30, 2020 contract liability balance.

Receivables and Allowance for Doubtful Accounts

Accounts receivables from customers are recorded at the invoiced amounts. Finance charges may be applied to trade receivables that are more than 30 days past due, and are recorded as finance charge income.

The allowance for doubtful accounts is the Company’s estimate of the amount of trade receivables that may not be collectible. The allowance is determined at an aggregate level by grouping accounts based on certain account criteria and its receivable aging. The allowance is based on both quantitative and qualitative factors, including historical loss experience, historical collection patterns, overdue status, aging trends, current and future economic conditions. The Company has an established process to periodically review current and past due trade receivable balances to determine the adequacy of the allowance. No single statistic or measurement determines the adequacy of the allowance. The total allowance reflects management’s estimate of losses inherent in its trade receivables at the balance sheet date. Different assumptions or changes in economic conditions could result in material changes to the allowance for doubtful accounts.

Changes in the allowance for credit losses are as follows:


(in thousands)	Credit Loss Allowance
Balance at September 30, 2021	$	4,779
Current period provision		5,264
Write-offs, net and other		(1,146	)
Balance as of June 30, 2022	$	8,897

- Definition

The entire disclosure of revenue from contract with customer to transfer good or service and to transfer nonfinancial asset. Includes, but is not limited to, disaggregation of revenue, credit loss recognized from contract with customer, judgment and change in judgment related to contract with customer, and asset recognized from cost incurred to obtain or fulfill contract with customer. Excludes insurance and lease contracts.

(c)

On July 6, 2022, the Company refinanced its five-year term loan and the revolving credit facility with the execution of the sixth amended and restated revolving credit facility agreement. (See Note 16—Subsequent Events). As of June 30, 2022, the Company has classified $69.1 million of its revolving credit facility borrowings as long term debt. Proceeds from the new term loan were used to repay the outstanding balance of the existing term loan ($95.9 million) and $69.1 million of the revolving credit facility borrowings.

On July 6, 2022, the Company refinanced the fifth amended and restated revolving credit facility with the execution of the sixth amended and restated revolving credit facility comprised of ten participants. The new credit agreement replaced the fifth amended and restated revolving credit facility agreement in its entirety, increased the Term Loan to $165 million, enabled the Company to borrow up to $400 million ($550 million during the heating season of December through April of each year) on a revolving credit facility for working capital purposes (subject to certain borrowing base limitations and coverage ratios) and extended the maturity date to July 6, 2027. Consistent with the fifth amended and restated revolving credit facility, the agreement allows for the issuance of up to $25 million in letters of credit.

The Company can increase the revolving credit facility size by an additional $200 million without the consent of the bank group. However, the bank group is not obligated to fund the $200 million increase. If the bank group elects not to fund the increase, the Company can add additional lenders to the group, with the consent of the Agent (as defined in the credit agreement), which shall not be unreasonably withheld. Obligations under the sixth amended and restated revolving credit facility agreement are guaranteed by the Company and its subsidiaries and are secured by liens on substantially all of the Company’s assets, including accounts receivable, inventory, general intangibles, real property, fixtures and equipment.

All amounts outstanding under the sixth amended and restated revolving credit facility become due and payable on the facility termination date of July 6, 2027. The Term Loan is repayable in quarterly payments of $4.1 million under the new credit agreement beginning January 1, 2023 with no quarterly payment due October 1, 2022, plus an annual payment equal to 25% of the annual Excess Cash Flow as defined in the credit agreement (an amount not to exceed $8.5 million annually), less certain voluntary prepayments made during the year, with final payment at maturity. In fiscal 2022 the Company repaid $4.9 million of additional loan repayments due to Excess Cash Flow related to fiscal 2021. In the first quarter of fiscal 2021 the banks waived the Excess Cash Flow requirement related to fiscal 2020. Under the Company’s sixth amended and restated revolving credit facility, the next annual Excess Cash Flow payment will be applicable for fiscal year ended September 30, 2023.

The interest rate on the fifth amended and restated revolving credit facility and the Term Loan was based on a margin over LIBOR or a base rate. At June 30, 2022, the effective interest rate on the Term Loan was approximately 4.4% and the effective interest rate on revolving credit facility borrowings was approximately 2.3%. At September 30, 2021, the effective interest rate on the term loan and revolving credit facility borrowings was approximately 4.3% and 2.5%, respectively. The interest rate on the revolving line of credit and the term loan under the sixth amended and restated revolving credit facility is based on a margin over Adjusted Term SOFR or a base rate.

The commitment fee on the unused portion of the revolving credit facility is 0.30% from December through April, and 0.20% from May through November.

The sixth amended and restated credit agreement requires the Company to meet certain financial covenants, including a Fixed Charge Coverage Ratio (as defined in the credit agreement) of not less than 1.1 as long as the Term Loan was outstanding or revolving credit facility availability was less than 12.5% of the facility size. In addition, as long as the Term Loan was outstanding, a senior secured leverage ratio could not be more than 3.0 as calculated as of the quarters ending June or September, and no more than 5.5 as calculated as of the quarters ending December or March.

Certain restrictions are also imposed by the sixth amended and restated credit agreement, including restrictions on the Company’s ability to incur additional indebtedness, to pay distributions to unitholders, to pay certain inter-company dividends or distributions, repurchase units, make investments, grant liens, sell assets, make acquisitions and engage in certain other activities.

At June 30, 2022, $95.9 million of the Term Loan was outstanding, $129.5 million amount was outstanding under the revolving credit facility, no hedge positions were secured under the credit agreement, and $5.1 million of letters of credit were issued and outstanding. At September 30, 2021, $110.5 million of the Term Loan was outstanding, $8.6 million was outstanding under the revolving credit facility, no hedge positions were secured under the credit agreement, and $3.1 million of letters of credit were issued and outstanding.

At June 30, 2022, availability was $124.4 million, and the Company was in compliance with the fixed charge coverage ratio and the senior secured leverage ratio. At September 30, 2021, availability was $171.5 million, and the Company was in compliance with the fixed charge coverage ratio and the senior secured leverage ratio.

- Definition

The entire disclosure for information about short-term and long-term debt arrangements, which includes amounts of borrowings under each line of credit, note payable, commercial paper issue, bonds indenture, debenture issue, own-share lending arrangements and any other contractual agreement to repay funds, and about the underlying arrangements, rationale for a classification as long-term, including repayment terms, interest rates, collateral provided, restrictions on use of assets and activities, whether or not in compliance with debt covenants, and other matters important to users of the financial statements, such as the effects of refinancing and noncompliance with debt covenants.

Summary of Significant Accounting Policies

2) Summary of Significant Accounting Policies

Basis of Presentation

The Consolidated Financial Statements include the accounts of Star and its subsidiaries. All material intercompany items and transactions have been eliminated in consolidation.

The financial information included herein is unaudited; however, such information reflects all adjustments (consisting solely of normal recurring adjustments), which are, in the opinion of management, necessary for the fair statement of financial condition and results for the interim periods. Due to the seasonal nature of the Company’s business, the results of operations and cash flows for the nine-month period ended June 30, 2022 are not necessarily indicative of the results to be expected for the full year.

These interim financial statements of the Company have been prepared in accordance with U.S. Generally Accepted Accounting Principles (“GAAP”) for interim financial information and Rule 10-01 of Regulation S-X of the U.S. Securities and Exchange Commission (the “SEC”) and should be read in conjunction with the financial statements included in the Company’s Annual Report on Form 10-K for the year ended September 30, 2021.

Comprehensive Income (Loss)

Comprehensive income (loss) is comprised of Net income (loss) and Other comprehensive income (loss). Other comprehensive income (loss) consists of the unrealized gain on amortization on the Company’s pension plan obligation for its two frozen defined benefit pension plans, unrealized loss on available-for-sale investments, unrealized gain on interest rate hedges and the corresponding tax effects.

Cash, Cash Equivalents, and Restricted Cash

The Company considers all highly liquid investments with an original maturity of three months or less when purchased to be cash equivalents. At June 30, 2022, the $9.2 million of cash, cash equivalents, and restricted cash on the Condensed Consolidated Statements of Cash Flows is composed of $9.0 million of cash and cash equivalents and $0.3 million of restricted cash. At September 30, 2021, the $5.0 million of cash, cash equivalents, and restricted cash on the Condensed Consolidated Statements of Cash Flows is composed of $4.8 million of cash and cash equivalents and $0.3 million of restricted cash. Restricted cash represents deposits held by our captive insurance company that are required by state insurance regulations to remain in the captive insurance company as cash.

Fair Value Valuation Approach

The Company uses valuation approaches that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible. The Company determines fair value based on assumptions that market participants would use in pricing an asset or liability in the principal or most advantageous market. When considering market participant assumptions in fair value measurements, the following fair value hierarchy distinguishes between observable and unobservable inputs, which are categorized in one of the following levels:

•

Level 1 inputs: Unadjusted quoted prices in active markets for identical assets or liabilities accessible to the reporting entity at the measurement date.

•

Level 2 inputs: Other than quoted prices included in Level 1 inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the asset or liability.

•

Level 3 inputs: Unobservable inputs for the asset or liability used to measure fair value to the extent that observable inputs are not available, thereby allowing for situations in which there is little, if any, market activity for the asset or liability at measurement date.

Captive Insurance Collateral

The captive insurance collateral is held by our captive insurance company in an irrevocable trust as collateral for certain workers’ compensation and automobile liability claims. The collateral is required by a third party insurance carrier that insures per claim amounts above a set deductible. If we did not deposit cash into the trust, the third party carrier would require that we issue an equal amount of letters of credit, which would reduce our availability under the sixth amended and restated credit agreement. Due to the expected timing of claim payments, the nature of the collateral agreement with the carrier, and our captive insurance company’s source of other operating cash, the collateral is not expected to be used to pay obligations within the next twelve months.

Unrealized gains and losses, net of related income taxes, are reported as accumulated other comprehensive income (loss), except for losses from impairments which are determined to be other-than-temporary. Realized gains and losses, and declines in value judged to be other-than-temporary on available-for-sale securities are included in the determination of net income and are included in Interest expense, net, at which time the average cost basis of these securities are adjusted to fair value.

Weather Hedge Contract

To partially mitigate the adverse effect of warm weather on cash flows, the Company has used weather hedge contracts for a number of years. Weather hedge contracts are recorded in accordance with the intrinsic value method defined by the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 815-45-15 Derivatives and Hedging, Weather Derivatives (EITF 99-2). The premium paid is included in the caption “Prepaid expenses and other current assets” in the accompanying balance sheets and amortized over the life of the contract, with the intrinsic value method applied at each interim period.

The Company entered into weather hedge contracts for fiscal year 2023. The hedge period runs from November 1 through March 31, taken as a whole. The “Payment Thresholds,” or strikes, are set at various levels and are referenced against degree days for the prior ten year average. The maximum that the Company can receive is $12.5 million per year. In addition, we are obligated to make an annual payment capped at $5.0 million if degree days exceed the Payment Threshold. For fiscal 2022 and 2021, we had weather hedge contracts with similar payment thresholds and terms. The temperatures experienced during the nine months ended June 30, 2022 and June 30, 2021 were warmer than the strikes in the weather hedge contracts. As a result at June 30, 2022 and June 30, 2021, the Company reduced delivery and branch expenses for the gains realized under those contracts of $1.1 million and $3.4 million, respectively. The amounts payable by the counterparties under the weather hedge contracts were received in full in April 2022 and April 2021, respectively.

New England Teamsters and Trucking Industry Pension Fund (“the NETTI Fund”) Liability

As of June 30, 2022, we had $0.2 million and $16.3 million balances included in the captions “Accrued expenses and other current liabilities” and “Other long-term liabilities,” on our Condensed Consolidated Balance Sheet representing the remaining balance of the NETTI Fund withdrawal liability. As of September 30, 2021, we had $0.2 million and $16.5 million balances reflected in these categories respectively. Based on the borrowing rates currently available to the Company for long-term financing of a similar maturity, the fair value of the NETTI Fund withdrawal liability as of June 30, 2022 and September 30, 2021 was $22.0 million and $25.8 million, respectively. We utilized Level 2 inputs in the fair value hierarchy of valuation techniques to determine the fair value of this liability.

Recently Adopted Accounting Pronouncements

The Company did not adopt new standards in the first nine months of fiscal 2022 that have a material impact on its consolidated financial statements and related disclosures.

Recently Issued Accounting Pronouncements

In October 2021, the FASB issued ASU No. 2021-08, Accounting for Contract Assets and Contract Liabilities from Contracts with Customers, which requires accounting for contract assets and liabilities from contracts with customers in a business combination to be accounted for in accordance with ASC No. 606. The standard is effective for fiscal years beginning after December 15, 2022. The Company has not determined the timing of adoption, but does not expect ASU 2021-08 to have a material impact on its consolidated financial statements and related disclosures.

Accounting Policies [Abstract]

Organization

1) Organization

Star Group, L.P. (“Star,” the “Company,” “we,” “us,” or “our”) is a full service provider specializing in the sale of home heating and air conditioning products and services to residential and commercial home heating oil and propane customers. The Company has one reportable segment for accounting purposes. We also sell diesel fuel, gasoline and home heating oil on a delivery only basis, and in certain of our marketing areas, we provide plumbing services primarily to our home heating oil and propane customer base. We believe we are the nation’s largest retail distributor of home heating oil based upon sales volume.

The Company is organized as follows:

•

Star is a limited partnership, which at June 30, 2022, had outstanding 36.5 million Common Units (NYSE: “SGU”), representing a 99.1% limited partner interest in Star, and 0.3 million general partner units, representing a 0.9% general partner interest in Star. Our general partner is Kestrel Heat, LLC, a Delaware limited liability company (“Kestrel Heat” or the “general partner”). The Board of Directors of Kestrel Heat (the “Board”) is appointed by its sole member, Kestrel Energy Partners, LLC, a Delaware limited liability company (“Kestrel”). Although Star is a partnership, it is taxed as a corporation and its distributions to unitholders are treated as taxable dividends.

•

Star owns 100% of Star Acquisitions, Inc. (“SA”), a Minnesota corporation that owns 100% of Petro Holdings, Inc. (“Petro”). SA and its subsidiaries are subject to Federal and state corporate income taxes. Star’s operations are conducted through Petro and its subsidiaries. Petro is primarily a Northeast and Mid-Atlantic U.S. region retail distributor of home heating oil and propane that at June 30, 2022 served approximately 421,000 full service residential and commercial home heating oil and propane customers and 73,200 customers on a delivery only basis. We also sell gasoline and diesel fuel to approximately 27,800 customers. We install, maintain, and repair heating and air conditioning equipment and to a lesser extent provide these services outside our heating oil and propane customer base including approximately 18,200 service contracts for natural gas and other heating systems.

•

Petroleum Heat and Power Co., Inc. (“PH&P”) is a wholly owned subsidiary of Star. PH&P is the borrower and Star is the guarantor of the sixth amended and restated credit agreement’s $165 million five-year senior secured term loan and the $400 million ($550 million during the heating season of December through April of each year) revolving credit facility, both due July 6, 2027. (See Note 11—Long-Term Debt and Bank Facility Borrowings and Note 16—Subsequent Events).

Derivative Instruments And Hedging Activities Disclosure [Abstract]

Derivatives and Hedging-Disclosures and Fair Value Measurements

6) Derivatives and Hedging—Disclosures and Fair Value Measurements

The Company uses derivative instruments such as futures, options and swap agreements in order to mitigate exposure to market risk associated with the purchase of home heating oil for price-protected customers, physical inventory on hand, inventory in transit, priced purchase commitments and internal fuel usage. FASB ASC 815-10-05 Derivatives and Hedging, established accounting and reporting standards requiring that derivative instruments be recorded at fair value and included in the consolidated balance sheet as assets or liabilities, along with qualitative disclosures regarding the derivative activity. The Company has elected not to designate its commodity derivative instruments as hedging derivatives, but rather as economic hedges whose change in fair value is recognized in its statement of operations in the caption “(Increase) decrease in the fair value of derivative instruments.” Depending on the risk being economically hedged, realized gains and losses are recorded in cost of product, cost of installations and services, or delivery and branch expenses.

As of June 30, 2022, to hedge a substantial majority of the purchase price associated with heating oil gallons anticipated to be sold to its price-protected customers, the Company held the following derivative instruments that settle in future months to match anticipated sales: 5.5 million gallons of swap contracts, 37.3 million gallons of call options, 2.1 million gallons of put options, and 17.6 million net gallons of synthetic call options. To hedge the inter-month differentials for its price-protected customers, its physical inventory on hand and inventory in transit, the Company, as of June 30, 2022, held 26.0 million gallons of swap contracts and 0.5 million gallons of short future contracts that settle in future months. To hedge its internal fuel usage and other activities for fiscal 2023, the Company held 0.4 million gallons of call options and swap contracts that settle in future months.

As of June 30, 2021, to hedge a substantial majority of the purchase price associated with heating oil gallons anticipated to be sold to its price-protected customers, the Company held the following derivative instruments that settle in future months to match anticipated sales: 8.9 million gallons of swap contracts, 5.3 million gallons of call options, 2.9 million gallons of put options, and 57.2 million net gallons of synthetic call options. To hedge the inter-month differentials for its price-protected customers, its physical inventory on hand and inventory in transit, the Company, as of June 30, 2021, held 3.8 million gallons of long future contracts and 21.5 million gallons of short future contracts that settle in future months. To hedge its internal fuel usage and other activities for fiscal 2021, the Company, as of June 30, 2021, held 3.6 million gallons of call options and swap contracts that settle in future months.

As of June 30, 2022, the Company has interest rate swap agreements in order to mitigate exposure to market risk associated with variable rate interest on $55.3 million, or 58%, of its long term debt. The Company has designated its interest rate swap agreements as cash flow hedging derivatives. To the extent these derivative instruments are effective and the accounting standard’s documentation requirements have been met, changes in fair value are recognized in other comprehensive income (loss) until the underlying hedged item is recognized in earnings. As of June 30, 2022 the fair value of the swap contracts was $1.3 million. As of September 30, 2021, the notional value of the swap contracts was $59.0 million and the fair value of the swap contracts was $(1.6) million. We utilized Level 2 inputs in the fair value hierarchy of valuation techniques to determine the fair value of the swap contracts.

The Company’s derivative instruments are with the following counterparties: Bank of America, N.A., Bank of Montreal, Cargill, Inc., Citibank, N.A., JPMorgan Chase Bank, N.A., Key Bank, N.A., Toronto-Dominion Bank and Wells Fargo Bank, N.A. The Company assesses counterparty credit risk and considers it to be low. We maintain master netting arrangements that allow for the non-conditional offsetting of amounts receivable and payable with counterparties to help manage our risks and record derivative positions on a net basis. The Company generally does not receive cash collateral from its counterparties and does not restrict the use of cash collateral it maintains at counterparties. At June 30, 2022, the aggregate cash posted as collateral in the normal course of business at counterparties was $0.1 million and recorded in “Prepaid expense and other current assets.” Positions with counterparties who are also parties to our credit agreement are collateralized under that facility. As of June 30, 2022, no hedge positions or payable amounts were secured under the credit facility.

The Company’s Level 1 derivative assets and liabilities represent the fair value of commodity contracts used in its hedging activities that are identical and traded in active markets. The Company’s Level 2 derivative assets and liabilities represent the fair value of commodity and interest rate contracts used in its hedging activities that are valued using either directly or indirectly observable inputs, whose nature, risk and class are similar. No significant transfers of assets or liabilities have been made into and out of the Level 1 or Level 2 tiers. All derivative instruments were non-trading positions and were either a Level 1 or Level 2 instrument. The Company had no Level 3 derivative instruments. The fair market value of our Level 1 and Level 2 derivative assets and liabilities are calculated by our counter-parties and are independently validated by the Company. The Company’s calculations are, for Level 1 derivative assets and liabilities, based on the published New York Mercantile Exchange (“NYMEX”) market prices for the commodity contracts open at the end of the period. For Level 2 derivative assets and liabilities the calculations performed by the Company are based on a combination of the NYMEX published market prices and other inputs, including such factors as present value, volatility and duration.

The Company had no assets or liabilities that are measured at fair value on a nonrecurring basis subsequent to their initial recognition. The Company’s commodity financial assets and liabilities measured at fair value on a recurring basis are listed on the following table.

Common Unit Repurchase and Retirement

4) Common Unit Repurchase and Retirement

In July 2012, the Board adopted a plan to repurchase certain of the Company’s Common Units that was amended in fiscal 2018 (the “Repurchase Plan”). Through August 2020, the Company had repurchased approximately 14.4 million Common Units under the Repurchase Plan. In August 2020, the Board authorized an increase of the number of Common Units that remained available for the Company to repurchase from 2.0 million to a total of 6.0 million, of which 4.9 million were available for repurchase in open market transactions and 1.1 million were available for repurchase in privately-negotiated transactions. There is no guarantee of the number of units that will be purchased under the Repurchase Plan and the Company may discontinue purchases at any time. The Repurchase Plan does not have a time limit. The Board may also approve additional purchases of units from time to time in private transactions. The Company’s repurchase activities take into account SEC safe harbor rules and guidance for issuer repurchases. All of the Common Units purchased under the Repurchase Plan will be retired.

Under the Company’s sixth amended and restated credit agreement dated July 6, 2022, in order to pay distributions and repurchase Common Units, we must maintain Availability (as defined in the sixth amended and restated credit agreement) of $60 million, 15.0% of the facility size of $400 million (assuming no borrowings under the seasonal advance) on a historical pro forma and forward-looking basis, and a fixed charge coverage ratio of not less than 1.15 measured as of the date of repurchase or distribution. (See Note 11—Long-Term Debt and Bank Facility Borrowings and Note 16—Subsequent Events)

The following table shows repurchases under the Repurchase Plan:


(in thousands, except per unit amounts)
Period	Total Number of Units Purchased		Average Price Paid per Unit (a)		Total Number of Units Purchased as Part of Publicly Announced Plans or Programs		Maximum Number of Units that May Yet Be Purchased

Income Tax Disclosure [Abstract]

Income Taxes

12) Income Taxes

The accompanying financial statements are reported on a fiscal year, however, the Company and its corporate subsidiaries file Federal and State income tax returns on a calendar year.

The current and deferred income tax expense for the three and nine months ended June 30, 2022, and June 30, 2021 are as follows:


	Three Months Ended						Nine Months Ended
	June 30,						June 30,
(in thousands)	2022			2021			2022		2021
Income (loss) before income taxes	$	(14,353	)	$	(15,963	)	$	120,253	$	154,041
Current income tax expense (benefit)		(7,058	)		(3,968	)		27,135		30,389
Deferred income tax expense		3,292			59			7,837		12,682
Total income tax expense (benefit)	$	(3,766	)	$	(3,909	)	$	34,972	$	43,071

At June 30, 2022, we did not have unrecognized income tax benefits.

Our continuing practice is to recognize interest and penalties related to income tax matters as a component of income tax expense. We file U.S. Federal income tax returns and various state and local returns. A number of years may elapse before an uncertain tax position is audited and finally resolved. For our Federal income tax returns we have four tax years subject to examination. In our major state tax jurisdictions of New York, Connecticut and Pennsylvania, we have four years that are subject to examination. In the state tax jurisdiction of New Jersey we have five tax years that are subject to examination. While it is often difficult to predict the final outcome or the timing of resolution of any particular uncertain tax position, based on our assessment of many factors, including past experience and interpretation of tax law, we believe that our provision for income taxes reflect the most probable outcome. This assessment relies on estimates and assumptions and may involve a series of complex judgments about future events.

- Definition

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

Quarterly Distribution Declared

In July 2022, we declared a quarterly distribution of $0.1525 per unit, or $0.61 per unit on an annualized basis, on all Common Units with respect to the third quarter of fiscal 2022, paid on August 2, 2022, to holders of record on July 25, 2022. The amount of distributions in excess of the minimum quarterly distribution of $0.0675 are distributed in accordance with our Partnership Agreement, subject to the management incentive compensation plan. As a result, $5.5 million was paid to the Common Unit holders, $0.3 million to the General Partner unit holders (including $0.3 million of incentive distribution as provided in our Partnership Agreement) and $0.3 million to management pursuant to the management incentive compensation plan which provides for certain members of management to receive incentive distributions that would otherwise be payable to the General Partner.

Common Units Repurchased and Retired

In July 2022, in accordance with the Repurchase Plan, the Company repurchased and retired 0.1 million Common Units at an average price paid of $9.73 per unit.

Sixth Amended and Restated Revolving Credit Facility Agreement

On July 6, 2022, the Company entered into a sixth amended and restated revolving credit facility agreement with a bank syndicate of ten participants that enables us to borrow up to $400 million ($550 million during the heating season of December through April of each year) on a revolving line of credit for working capital purposes (subject to certain borrowing base limitations and coverage ratios), provides for a $165 million five-year senior secured term loan, allows for the issuance of up to $25 million in letters of credit, and extends the maturity date of the previous agreement to July 6, 2027. Proceeds from the new term loan were used to repay the outstanding balance of the existing term loan ($95.9 million) and $69.1 million of the revolving credit facility borrowings.

Under the Company’s sixth amended and restated credit agreement, in order to pay distributions and repurchase Common Units we must maintain Availability of $60 million, 15.0% of the facility size of $400 million (assuming the non-seasonal aggregate commitment is outstanding) on a historical pro forma and forward-looking basis, and a fixed charge coverage ratio of not less than 1.15 measured as of the date of repurchase or distribution.

In any accounting period where the Company’s aggregate net income exceeds its aggregate distribution for such period, the Company is required to present net income per Limited Partner unit as if all of the earnings for the period were distributed, based on the terms of the Partnership agreement, regardless of whether those earnings would actually be distributed during a particular period from an economic or practical perspective. This allocation does not impact the Company’s overall net income or other financial results.

Commitments And Contingencies Disclosure [Abstract]

Commitments and Contingencies

14) Commitments and Contingencies

The Company’s operations are subject to the operating hazards and risks normally incidental to handling, storing and transporting and otherwise providing for use by consumers hazardous liquids such as home heating oil and propane. In the ordinary course of business, the Company is a defendant in various legal proceedings and litigation. The Company records a liability when it is probable that a loss has been incurred and the amount is reasonably estimable. We do not believe these matters, when considered individually or in the aggregate, could reasonably be expected to have a material adverse effect on the Company’s results of operations, financial position or liquidity.

The Company maintains insurance policies with insurers in amounts and with coverages and deductibles we believe are reasonable and prudent. However, the Company cannot assure that this insurance will be adequate to protect it from all material expenses related to current and potential future claims, legal proceedings and litigation, as certain types of claims may be excluded from our insurance coverage. If we incur substantial liability and the damages are not covered by insurance, or are in excess of policy limits, or if we incur liability at a time when we are not able to obtain liability insurance, then our business, results of operations and financial condition could be materially adversely affected.
