Accounting Policies [Abstract]
Accounting Policies	Accounting Policies Basis of Presentation and Consolidation The Company has historically operated as part of Select. The unaudited condensed consolidated financial statements of the Company have been prepared from Select’s historical accounting records and are derived from the condensed consolidated financial statements of Select to present the Company as if it had been operating on a standalone basis. The unaudited condensed consolidated financial statements of the Company as of September 30, 2024, and for the three and nine month periods ended September 30, 2024 and 2023, have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”) for interim reporting and the accounting principles generally accepted in the United States of America (“U.S. GAAP”). Accordingly, certain information and disclosures required by GAAP, which are normally included in the notes to the consolidated financial statements, have been condensed or omitted pursuant to those rules and regulations, although the Company believes the disclosure is adequate to make the information presented not misleading. In the opinion of management, such information contains all adjustments, which are normal and recurring in nature, necessary for a fair statement of the financial position, results of operations and cash flow for such periods. The results of operations for the three and nine months ended September 30, 2024 are not necessarily indicative of the results to be expected for the full fiscal year ended December 31, 2024. These unaudited condensed consolidated financial statements and related notes should be read in conjunction with the audited consolidated financial statements and related notes as contained in the Company’s registration statement on Form S-1, as amended (File No. 333-280242) (the “Registration Statement”). The condensed consolidated financial statements include the assets, liabilities, revenue, and expenses based on our legal entity structure as well as direct and indirect costs that are attributable to our operations. Indirect costs are the costs of support functions that are partially provided on a centralized basis by Select and its affiliates, which include finance, human resources, benefits administration, procurement support, information technology, legal, corporate governance and other professional services. Indirect costs have been allocated to us for the purposes of preparing the condensed consolidated financial statements based on a specific identification basis or, when specific identification is not practicable, a proportional cost allocation method, primarily based on headcount or other allocation methodologies that are considered to be a reasonable reflection of the utilization of services provided or the benefit received by us during the periods presented, depending on the nature of the services received. The income tax amounts in these condensed consolidated financial statements have been calculated based on a separate return methodology and are presented as if our income gave rise to separate federal and state consolidated income tax return filing obligations in the respective jurisdictions in which we operate. Adjustments to income tax expense resulting from the application of the separate return methodology, as compared to tax obligations determined by the Company’s inclusion in the Parent’s consolidated income tax provision, were assumed to be immediately settled with the Parent through Contributed Capital/Capital in Excess of Par as reflected on the Condensed Consolidated Balance Sheets, and reflected as a (Distribution)/Contribution to Parent on the Condensed Consolidated Statements of Changes in Stockholders’/Members’ Equity and the Condensed Consolidated Statements of Cash Flows within financing activities. The condensed consolidated financial statements include the accounts of the Company and the subsidiaries and variable interest entities in which the Company has a controlling financial interest. All intercompany balances and transactions within the Company are eliminated in consolidation. Transactions between the Company and Select have been included in these consolidated financial statements. The transfers with Select are expected to be settled in cash, other than the assumed income tax settlement noted above, and are reflected within the consolidated statement of cash flows as an operating or financing activity determined by the nature of the transaction. Select’s third-party debt and related interest expense have not been attributed to the Company because the Company is not the primary legal obligor of the debt and the borrowings are not specifically identifiable to the Company. However, the Company was a guarantor for Select’s senior notes and credit facilities until the guarantee was released at the closing of the IPO. The Company maintains its own cash management system and does not participate in a centralized cash management arrangement with Select. Recent Accounting Guidance Not Yet Adopted Segment Reporting In November 2023, FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which is intended to improve disclosure of segment information so that investors can better understand an entity’s overall performance. The ASU requires entities to quantitatively disclose significant segment expenses that are regularly provided to the chief operating decision maker for each reportable segment, as well as the amount of other segment items for each reportable segment and a description of what the other segment items are comprised. Disclosure of multiple measures of profit or loss will be permitted by the ASU. The Company will adopt ASU 2023-07 beginning with our annual reporting period ending December 31, 2024. The ASU is required to be applied retrospectively to all periods presented in the financial statements. The Company is currently reviewing ASU 2023-07, but does not expect it to have a significant impact on the disclosures in our consolidated financial statements. Income Taxes In December 2023, FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which is intended to improve the transparency and decision usefulness of income tax disclosures. The ASU includes enhanced requirements on the rate reconciliation, including specific categories that must be disclosed, and provides a threshold over which reconciling items must be disclosed. The amendments in the update also require annual disclosure of income taxes paid, disaggregated by federal, state, and foreign taxes, as well as any individual jurisdictions in which income taxes paid is greater than 5% of total income taxes paid. The ASU is effective for annual periods beginning after December 15, 2024; however early adoption is permitted. The ASU can be applied either prospectively or retrospectively. The Company is currently reviewing the impact that ASU 2023-09 will have on the disclosures in our consolidated financial statements. Expense Disaggregation In November 2024, FASB issued ASU 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40), which is intended to improve the disclosures of expenses by providing more detailed information about the types of expenses in commonly presented expense captions. The ASU requires entities to disclose the amounts of purchases of inventory, employee compensation, depreciation and intangible asset amortization included in each relevant expense caption; as well as a qualitative description of the amounts remaining in relevant expense captions that are not separately disaggregated quantitatively. The amendment also requires disclosure of the total amount of selling expense and, in annual reporting periods, an entity’s definition of selling expenses. The ASU is effective for annual periods beginning after December 15, 2026, and interim periods beginning after December 15, 2027; however early adoption is permitted. The ASU can be applied either prospectively or retrospectively. The Company is currently reviewing the impact that ASU 2024-03 will have on the disclosures in our consolidated financial statements. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, and expenses. Actual results could differ from those estimates.
