The preparation of these condensed consolidated financial statements in conformity with GAAP requires the Company to make estimates and assumptions that affect amounts reported in the condensed consolidated financial statements and the accompanying notes. Significant estimates in these condensed consolidated financial statements include allowances on accounts receivable, inventory, and deferred taxes, as well as estimates for accrued warranty expenses, goodwill and the ability of goodwill to be realized, revenue deferrals, effects of stock-based compensation and warrants, contingent liabilities, the provision or benefit for income taxes, and preferred stock. Due to the inherent uncertainty involved in making estimates, actual results reported in future periods may differ materially from those estimates.

Critical Accounting Policies

Information with respect to the Company’s critical accounting policies, which management believes could have the most significant effect on the Company’s reported results and require subjective or complex judgments by management, is discussed in the Company’s 2023 audited financial statements included in the 2023 Form 10-K.
