Accounting Policies [Abstract] |
Basis of Presentation | Basis of Presentation The accompanying consolidated financial statements include the accounts of the Company and its subsidiaries over which the Company has a controlling financial interest, and have been prepared in accordance with accounting principles generally accepted in the United States, or U.S. GAAP, and the rules and regulations of the U.S. Securities and Exchange Commission, or SEC. All intercompany balances and transactions have been eliminated in consolidation. (b)Basis of Presentation for Interim Periods Certain information and footnote disclosures normally included for the annual financial statements prepared in accordance with U.S. GAAP have been condensed or omitted for the interim periods presented. Management believes that the unaudited interim financial statements include all adjustments (which are normal and recurring in nature) necessary to present fairly the financial position of the Company and the results of operations and cash flows for the periods presented. The results of operations for the interim periods presented are not necessarily indicative of results that may be expected for the year or future periods. The financial statements should be read in conjunction with our audited consolidated financial statements and the notes thereto for the year ended September 30, 2021 included in our Annual Report on Form 10-K for the fiscal year then ended (the "2021 10-K"). The Company has continued to follow the accounting policies set forth in those financial statements.
Estimates | Estimates The preparation of these financial statements, in conformity with U.S. GAAP, requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent liabilities, and the reported amounts of revenue and expenses. At each reporting period end, we make estimates, including those related to revenue recognition and cost estimation on certain contracts, the realizability of goodwill, and amounts related to income taxes, certain accrued liabilities, and contingencies and litigation. We base our estimates on historical experience and expectations of the future that we believe to be reasonable. The economic and political effects of the COVID-19 global pandemic increase uncertainty, which has reduced our ability to use past results to estimate future performance. Accordingly, our estimates may be subject to greater volatility than has been the case in the past.
