Accounting Policies [Abstract]
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 six-month period ended March 31, 2023 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, 2022. Comprehensive Income Comprehensive income is comprised of Net income 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 gain (loss) on available-for-sale investments, unrealized gain (loss) 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 March 31, 2023, the $22.3 million of cash, cash equivalents, and restricted cash on the Condensed Consolidated Statements of Cash Flows is composed of $22.1 million of cash and cash equivalents and $0.3 million of restricted cash. At September 30, 2022, the $14.9 million of cash, cash equivalents, and restricted cash on the Condensed Consolidated Statements of Cash Flows is composed of $14.6 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. Assets Held for Sale Assets held for sale at September 30, 2022 represent certain heating oil assets that the Company sold on October 25, 2022. The carrying amount of the assets held for sale included $2.2 million of goodwill and $0.8 million of property and equipment, net. We measure and record assets held for sale at the lower of their carrying amount or fair value less cost to sell. The carrying amounts of the assets held for sale approximated their fair value at September 30, 2022. 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 years 2022 and 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 amount 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. The temperatures experienced during the hedge period through March 31, 2023 and March 31, 2022 were warmer than the strikes in the weather hedge contracts. As a result at March 31, 2023 and March 31, 2022, the Company reduced delivery and branch expenses and recorded receivable under those contracts of $12.5 million and $1.1 million, respectively. The amounts were received in full in April 2023 and April 2022, respectively. For fiscal 2024, the Company entered into a weather hedge contract with the similar hedge period described above. The maximum that the Company can receive is $12.5 million annually and the Company has no obligation to pay the counterparty should degree days exceed the Payment Threshold. New England Teamsters and Trucking Industry Pension Fund (“the NETTI Fund”) Liability As of March 31, 2023, we had $0.3 million and $16.1 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, 2022, we had $0.3 million and $16.2 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 March 31, 2023 and September 30, 2022 was $20.6 million and $20.2 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 In December 2022, the FASB issued ASU No. 2022-06, Reference Rate Reform (Topic 848) Facilitation of the Effects of Reference Rate Reform on Financial Reporting. The Company adopted the ASU effective December 31, 2022. The update extends the sunset of Topic 848 from December 31, 2022 to December 31, 2024. The guidance provides optional guidance for a limited period of time to ease potential accounting impacts associated with transitioning away from reference rates that are expected to be discontinued, such as interbank offered rates and LIBOR. The Company has $51.5 million of interest rate swap agreements at March 31, 2023 that are benchmarked against LIBOR, which the Company has designated as cash flow hedging derivatives. This guidance includes practical expedients for contract modifications due to reference rate reform. The Company has elected to adopt the practical expedient that the Company may change the contractual terms of the interest rate swap agreements that are expected to be affected by reference rate reform and not be required to de-designate the hedging relationships. The Company's adoption of the ASU did not have an impact on the Company’s 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.

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 six-month period ended March 31, 2023 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, 2022.

Comprehensive Income

Comprehensive income is comprised of Net income 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 gain (loss) on available-for-sale investments, unrealized gain (loss) 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 March 31, 2023, the $22.3 million of cash, cash equivalents, and restricted cash on the Condensed Consolidated Statements of Cash Flows is composed of $22.1 million of cash and cash equivalents and $0.3 million of restricted cash. At September 30, 2022, the $14.9 million of cash, cash equivalents, and restricted cash on the Condensed Consolidated Statements of Cash Flows is composed of $14.6 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.

Assets Held for Sale

Assets held for sale at September 30, 2022 represent certain heating oil assets that the Company sold on October 25, 2022. The carrying amount of the assets held for sale included $2.2 million of goodwill and $0.8 million of property and equipment, net. We measure and record assets held for sale at the lower of their carrying amount or fair value less cost to sell. The carrying amounts of the assets held for sale approximated their fair value at September 30, 2022.

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 years 2022 and 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 amount 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. The temperatures experienced during the hedge period through March 31, 2023 and March 31, 2022 were warmer than the strikes in the weather hedge contracts. As a result at March 31, 2023 and March 31, 2022, the Company reduced delivery and branch expenses and recorded receivable under those contracts of $12.5 million and $1.1 million, respectively. The amounts were received in full in April 2023 and April 2022, respectively.

For fiscal 2024, the Company entered into a weather hedge contract with the similar hedge period described above. The maximum that the Company can receive is $12.5 million annually and the Company has no obligation to pay the counterparty should degree days exceed the Payment Threshold.

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

As of March 31, 2023, we had $0.3 million and $16.1 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, 2022, we had $0.3 million and $16.2 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 March 31, 2023 and September 30, 2022 was $20.6 million and $20.2 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

In December 2022, the FASB issued ASU No. 2022-06, Reference Rate Reform (Topic 848) Facilitation of the Effects of Reference Rate Reform on Financial Reporting. The Company adopted the ASU effective December 31, 2022. The update extends the sunset of Topic 848 from December 31, 2022 to December 31, 2024. The guidance provides optional guidance for a limited period of time to ease potential accounting impacts associated with transitioning away from reference rates that are expected to be discontinued, such as interbank offered rates and LIBOR. The Company has $51.5 million of interest rate swap agreements at March 31, 2023 that are benchmarked against LIBOR, which the Company has designated as cash flow hedging derivatives. This guidance includes practical expedients for contract modifications due to reference rate reform. The Company has elected to adopt the practical expedient that the Company may change the contractual terms of the interest rate swap agreements that are expected to be affected by reference rate reform and not be required to de-designate the hedging relationships. The Company's adoption of the ASU did not have an impact on the Company’s 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.
