Accounting Policies [Abstract] |
Basis of Presentation | 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.
Use of Estimates | 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.
