Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Basis of Presentation | Basis of Presentation and Principles of Consolidation The accompanying consolidated financial statements include the accounts of DLH Holdings Corp. and its wholly-owned subsidiaries (together with its subsidiaries, "DLH" or the "Company" and also referred to as "we," "us" and "our"). All significant intercompany balances and transactions have been eliminated in consolidation. The accompanying financial statements have been prepared in accordance with United States generally accepted accounting principles ("GAAP") for interim financial information and with the instructions to Form 10-Q and Regulation S-X. Accordingly, these statements do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In management's opinion, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the period ended December 31, 2022 are not necessarily indicative of the results that may be expected for the year ending September 30, 2023 or any future period. Amounts as of and for the three months ended December 31, 2022 and December 31, 2021 are unaudited. For further information, refer to the consolidated financial statements and footnotes thereto included in the Company's Annual Report on Form 10-K for the year ended September 30, 2022 filed with the Securities and Exchange Commission on December 5, 2022.
