Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Basis of Presentation | Basis of Presentation The accompanying consolidated financial statements include the accounts of DLH Holdings Corp. and its subsidiaries (together with its subsidiaries, "DLH" or the "Company" and also referred to as "we," "us" and "our"), all of which are wholly owned. All significant intercompany balances and transactions have been eliminated in consolidation. The accompanying financial statements have been prepared in accordance with U.S. generally accepted accounting principles ("GAAP") for interim financial information and with the instructions to Form 10-Q and Article 10 of 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, 2020 are not necessarily indicative of the results that may be expected for the year ending September 30, 2021. Amounts as of and for the periods ended December 31, 2020 and December 31, 2019 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, 2020 filed with the Securities and Exchange Commission on December 7, 2020.
