Table of Content Property, plant and equipment. Property, plant and equipment are stated at cost less accumulated depreciation and amortization. Leasehold improvements are amortized over the shorter of their respective useful life or the lease term. Depreciation and amortization of assets are computed by the straight-line method over the following estimated useful lives of the assets: Classification Useful Life Buildings 20-40 years Enterprise Resource Planning ("ERP”) System 15 years Leasehold improvements 2-15 years Machinery and equipment 2-12 years Furniture and fixtures 2-10 years Computers and computer software 2-5 years Automobiles 2-5 years Intangible assets. Intangible assets with finite lives are amortized over their respective estimated useful lives to their estimated residual values and reviewed for impairment in accordance with ASC 360-10 Impairment or Disposal of Long-Lived Assets ("ASC 360”). Impairment of Long-lived Assets. We review our property and equipment, intangible assets subject to amortization and other long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset class may not be recoverable. Indicators of potential impairment include: an adverse change in legal factors or in the business climate that could affect the value of the asset in that asset class; an adverse change in the extent or manner in which the asset is used or is expected to be used, or in its physical condition; and current or forecasted operating or cash flow losses that demonstrate continuing losses associated with the use of the asset. If indicators of impairment are present, the asset is tested for recoverability by comparing the carrying value of the asset to the related estimated undiscounted future cash flows expected to be derived from the asset. If the expected undiscounted cash flows are less than the carrying value of the asset, then the asset is considered to be impaired and its carrying value is written down to fair value, based on the related estimated discounted cash flows. There were no impairment charges in 2023 or 2022. Income taxes. We follow the guidance of ASC 740 Income Taxes ("ASC 740”), which requires that we use the asset and liability method of accounting for deferred income taxes and provide deferred income taxes for all significant temporary differences. As part of the process of preparing our consolidated financial statements, we are required to estimate our income taxes in each of the jurisdictions in which we operate. This process involves estimating our actual current tax payable or receivable and related tax expense or benefit together with assessing temporary differences resulting from differing treatment of certain items such as depreciation for tax and accounting purposes. These differences can result in deferred tax assets and liabilities, which are included within our consolidated balance sheets. In accordance with ASC 740, we are required to assess the likelihood that our deferred tax assets will be realized and, to the extent we believe it is more likely than not (a likelihood of more than 50%) that some portion or all of the deferred tax assets will not be realized, we must establish a valuation allowance. We consider all available evidence to determine whether, based on the weight of the evidence, a valuation allowance is needed. Evidence used includes the reversal of existing taxable temporary differences, taxable income in prior carryback years if carryback is permitted by tax law, information about our current financial position and our results of operations for the current and preceding years, as well as all currently available information about future years, including our anticipated future performance and tax planning strategies. We regularly assess whether it is more likely than not that we will realize the deferred tax assets in the jurisdictions we operate in. We believe future sources of taxable income, reversing temporary differences and other tax planning strategies will be sufficient to realize the deferred tax assets for which no valuation allowance has been established. Our valuation allowance primarily relates to net operating loss carryforwards. While we have considered these factors in assessing the need for additional valuation allowance, there is no assurance that additional valuation allowance would not need to be established in the future if information about future years change. Any changes in valuation allowance would impact our income tax provision and net income (loss) in the period in which such a determination is made. As of December 31, 2023, our deferred tax assets were $111.5 million, less a valuation allowance of $93.7 million. As of December 31, 2023, our deferred tax liabilities were $22.4 million. Significant judgment is required in assessing the timing and amounts of deductible and taxable items for tax purposes. In accordance with ASC 740-10, we establish reserves for uncertain tax positions when, despite our belief that our tax return positions are supportable, we believe that it is not more likely than not that the position will be sustained upon challenge. When facts and circumstances change, we adjust these reserves through our provision for income taxes. To the extent interest and penalties may be assessed by taxing authorities on any related underpayment of income tax, such amounts have been accrued 35
