Accounting Policies [Abstract] |
Significant Accounting Policies | SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The accompanying consolidated financial statements, including the notes, include the accounts of the Company and its wholly-owned subsidiaries and have been prepared in accordance with accounting principles generally accepted in the United States ("U.S. GAAP") and the rules and regulations of the U.S. Securities and Exchange Commission ("SEC"). All intercompany balances and transactions have been eliminated in consolidation. 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. We believe that the unaudited interim financial statements include all adjustments (which are normal and recurring in nature) necessary to present fairly our financial position 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, 2022 included in our Annual Report on Form 10-K for the fiscal year then ended (the "2022 10-K"). We have continued to follow the accounting policies set forth in those financial statements. Use of 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. In May 2021, we acquired VES Group, Inc. As part of the acquisition, we allocated a valuation of $27 million to certain technology assets used by the business, which we elected to amortize over twelve years, which was our best estimate of asset life at that time. In fiscal year 2023, we have taken the opportunity to improve our technology portfolio, including the development of technology, which will eventually replace much of the acquired technology. Accordingly, we have revised the asset life on the existing technology assuming the assets will cease being used by September 2026. This change in estimated useful life will result in additional annual amortization expense of $3.8 million per year. In the three and nine months ended June 30, 2023, this change reduced our diluted earnings per share by approximately $0.01 and $0.03, respectively. In June 2023, we recorded an expense of $22.1 million for our best estimate of the investigation and remediation costs of a cybersecurity incident, reducing diluted earnings per share by approximately $0.26 for the three and nine months ended June 30, 2023, respectively. The estimated impact and expense is based on information currently available and the actual impact and expense may be greater than our estimates.
