Accounting Policies [Abstract] |
Basis of Presentation | 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, 2021 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, 2020.
Comprehensive Income | Comprehensive Income Comprehensive income is comprised of Net income and Other comprehensive income. Other comprehensive income 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 | 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, 2021, the $9.1 million of cash, cash equivalents, and restricted cash on the Condensed Consolidated Statements of Cash Flows is composed of $8.9 million of cash and cash equivalents and $0.3 million of restricted cash. At September 30, 2020, the $57.2 million of cash, cash equivalents, and restricted cash on the Condensed Consolidated Statements of Cash Flows is composed of $56.9 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 | 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 | 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 fifth 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 gain (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 | 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 2020 and 2021. Under these contracts, we are entitled to receive a payment if the total number of degree days within the hedge period is less than the prior ten year average. The hedge period runs from November 1 through March 31, taken as a whole, for each respective fiscal year. The “Payment Thresholds,” or strikes, are set at various levels for fiscal 2020 and 2021. The maximum that the Company could receive is $12.5 million per year. In addition, for fiscal 2020 and 2021 we were obligated to make an annual payment capped at $5.0 million if degree days exceed the Payment Threshold. As of March 31, 2021, the Company reduced delivery and branch expense and recorded a receivable under these contracts of $3.4 million, and received the amount in full in April 2021. As of March 31, 2020, the Company reduced delivery and branch expense and recorded a receivable under these contracts of $10.1 million, and received the amount in full in April 2020. For fiscal 2022, the Company entered into a weather hedge contract with similar terms described above. The maximum that the Company can receive is $7.5 million and we do not have a potential obligation to pay.
New England Teamsters and Trucking Industry Pension Fund ("the NETTI Fund") Liability | New England Teamsters and Trucking Industry Pension Fund (“the NETTI Fund”) Liability As of March 31, 2021, we had $0.2 million and $16.6 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, 2020, we had $0.2 million and $16.7 million balances included in the captions “Accrued expenses and other current liabilities” and “Other long-term liabilities,” on our Condensed Consolidated Balance Sheet. 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, 2021 and September 30, 2020 was $25.6 million and $29.0 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 | Recently Adopted Accounting Pronouncements In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments – Credit Losses. The update broadens the information that an entity should consider in developing expected credit loss estimates, eliminates the probable initial recognition threshold, and allows for the immediate recognition of the full amount of expected credit losses. The Company adopted ASU No. 2016-13 effective October 1, 2020. The adoption of ASU No. 2016-13 did not have a material impact on the Company’s consolidated financial statements and related disclosures. See Note 3 – Revenue Recognition. In January 2017, the FASB issued ASU No. 2017-04, Intangibles – Goodwill and Other (Topic 230): Simplifying the Test for Goodwill Impairment. The update simplifies how an entity is required to test goodwill for impairment. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value, but not exceed the total amount of goodwill allocated to the reporting unit. The Company adopted ASU No. 2017-04 effective October 1, 2020. The adoption of ASU No. 2017-04 did not have an impact on the Company’s consolidated financial statements and related disclosures. In August 2018, the FASB issued ASU No. 2018-14, Compensation - Retirement Benefits - Defined Benefit Plans - General: Changes to the Disclosure Requirements for Defined Benefit Plans, which modifies the disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans by removing and adding certain disclosures for these plans. The Company adopted ASU No. 2018-14 effective October 1, 2020. The adoption of ASU No. 2018-15 did not have an impact on the Company’s consolidated financial statements and related disclosures. In August 2018, the FASB issued ASU No. 2018-15, Intangibles—Goodwill and Other—Internal-Use Software: Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract, which will align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. The Company adopted ASU No. 2018-15 effective October 1, 2020. The adoption of ASU No. 2018-15 did not have an impact on the Company’s consolidated financial statements and related disclosures.
