Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Basis of Presentation | The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and its subsidiaries that are majority-owned or otherwise controlled by the Company, and have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) and the rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”) and should be read in conjunction with the information contained in the Company's Annual Report on Form 10-K for the year ended March 31, 2024. The interim period unaudited condensed consolidated financial statements are presented as described below. Certain information and disclosures normally required for annual financial statements have been condensed or omitted pursuant to GAAP and SEC rules and regulations. In the opinion of management, all adjustments considered necessary for fair presentation of the results of the interim periods presented have been included. The Company’s fiscal year ends on March 31 and, unless otherwise noted, references to fiscal year or fiscal are for fiscal years ended March 31. The results of operations for the nine months ended December 31, 2024 are not necessarily indicative of results to be expected for the full fiscal year. The condensed consolidated financial statements and notes of the Company include its subsidiaries, and other entities over which the Company has a controlling financial interest or where the Company is a primary beneficiary. Certain amounts reported in the Company's prior fiscal year condensed consolidated financial statements have been reclassified to conform to the current fiscal year presentation.
Investments in Variable Interest Entities and Other Investments | Investments in Variable Interest Entities and Other Investments The Company invests in certain companies that advance or develop new technologies applicable to its business. Each investment is evaluated for consolidation under the variable interest entities model and/or the voting interest model. The Company uses the equity method to account for investments in entities that it does not control if it is otherwise able to exert significant influence over the entities' operating and financial policies. Equity investments in entities over which the Company does not have the ability to exercise significant influence and whose securities do not have a readily determinable fair value are accounted for under the measurement alternative, where they are subject to fair value adjustments in certain circumstances (e.g., observable price changes or impairment). The results of our investments are not material to the unaudited condensed and consolidated financial statements for the periods presented. As of December 31, 2024 and March 31, 2024, respectively, the total of equity and other investments related to unconsolidated entities included in other long term assets of the Company’s condensed consolidated balance sheet were $67.2 million and $42.0 million.
Accounting Estimates | Accounting Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses, as well as the disclosure of contingent assets and liabilities at the date of the financial statements or during the relevant reporting periods (as applicable). The Company bases its estimates on assumptions, both historical and forward-looking, that it believes are reasonable and appropriate. Actual results may differ materially from those estimates. Estimates are used for, but not limited to, revenue recognition including the profitability of long-term contracts and indirect costs accruals, the provision for claimed costs, fair value measurements and the valuation and expected lives of intangible assets, incentive compensation, income taxes including reserves for uncertain tax positions, postretirement obligations and contingencies. See Note 2, “Summary of Significant Accounting Policies” to the Company’s consolidated financial statements included in the Annual Report on Form 10-K for the year ended March 31, 2024 for further details on significant estimates and assumptions used.
Recently Issued Accounting Pronouncements Not Yet Adopted and Recently Issued Accounting Pronouncements Adopted | Recently Issued Accounting Pronouncements Not Yet Adopted In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-07, Improvements to Reportable Segment Disclosures, which enhances reportable segment disclosure requirements, including significant segment expenses and interim disclosures (“Topic 280”). The guidance allows for disclosure of multiple measures of a segment’s profit or loss, and it requires that public entities with a single reportable segment provide all disclosures required by the ASU and all existing disclosures in Topic 280. ASU 2023-07 is effective for annual periods beginning after December 15, 2023 and interim periods within fiscal years beginning after December 15, 2024. The amendments are to be applied retrospectively, and early adoption is permitted. The Company is currently assessing the impact of this update and does not expect this update to have a material impact on its present or historical consolidated financial statements. In December 2023, the FASB issued ASU 2023-09, Improvements to Income Tax Disclosures, which requires disclosure of disaggregated information about an entity’s effective tax rate reconciliation as well as information on income taxes paid. The ASU is effective for annual periods beginning after December 15, 2024, and should be applied prospectively. The Company plans to adopt this standard in fiscal 2026 and is currently evaluating the impact of adoption of this standard on its financial statement disclosures. In November 2024, the FASB issued ASU 2024-03, Disaggregation of Income Statement Expenses, which is intended to enhance transparency into the nature and function of certain expenses. The guidance does not change the expense captions an entity presents on the face of the income statement; rather, it requires public business entities to provide disaggregated disclosures of certain expense captions in the notes to the financial statements. The ASU is effective for annual periods beginning after December 15, 2026 and interim periods within fiscal years beginning after December 15, 2027, and should be applied prospectively. The Company is currently assessing the impact of this update. Recently Issued Accounting Pronouncements Adopted There have been no recently adopted accounting pronouncements that are material to the Company's consolidated financial statements.
Revenue | Contract Estimates We recognize revenue for many of our fixed price contracts under a contract cost-based input method and require an Estimate-at-Completion (“EAC”) process, which management uses to review and monitor the progress towards the completion of our performance obligations. Under this process, management considers various inputs and assumptions related to the EAC, including, but not limited to, progress towards completion, labor costs and productivity, material and subcontractor costs, and identified risks. Estimating the total cost at the completion of our performance obligations is subjective and requires management to make assumptions about future activity and cost drivers under the contract. Changes in these estimates can occur for a variety of reasons and, if significant, may impact the profitability of the Company’s contracts. Changes in estimates related to contracts accounted for under the EAC process are recognized on a cumulative catch-up basis in the period when such changes are determinable and reasonably estimable. If the estimate of contract profitability indicates an anticipated loss on a contract, the Company recognizes the total loss at the time it is identified. For each of the three and nine months ended December 31, 2024 and 2023, the aggregate impact of adjustments in contract estimates was not material. Disaggregation of Revenue We disaggregate our revenue from contracts with customers by contract type and by customer type, as well as by whether the Company acts as prime contractor or sub-contractor, as we believe these categories best depict how the nature, amount, timing and uncertainty of our revenue and cash flows are affected by economic factors. The following series of tables presents our revenue disaggregated by these categories. Remaining performance obligations represent the transaction price of exercised contracts for which work has not yet been performed, irrespective of whether funding has or has not been authorized and appropriated as of the date of exercise. Remaining performance obligations exclude negotiated but unexercised options, the unfunded value of expired contracts, and certain variable consideration which the Company does not expect to recognize as revenue.
