18. INCOME TAXES
The Company’s provision for interim periods is determined using an estimate of the annual effective tax rate, adjusted for discrete items arising in that quarter. The Company’s effective tax rate differs from the U.S. statutory tax rate primarily due to valuation allowances on its deferred tax assets as it is more likely than not that some or all of the Company’s deferred tax assets will not be realized. During the three and nine months ended September 30, 2023, the Company recorded a benefit of $0.1 million and $0.7 million, respectively. During the three and nine months ended September 30, 2022, the Company recorded an income tax expense of $0.6 million and an income tax benefit of $1.6 million, respectively.
The Company recognizes deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the Company’s condensed consolidated financial statements and tax returns. Deferred tax assets and liabilities are determined based upon the differences between the condensed consolidated financial statements carrying amounts and the tax bases of existing assets and liabilities and for loss and credit carryforwards, using enacted tax rates expected to be in effect in the years in which the differences are expected to reverse. As a result of the fact that the Company has incurred tax losses from inception, the Company maintains that it is more likely than not that the Company would not realize the benefits of federal and state net deferred tax assets nor the benefits of deferred tax assets in certain non-U.S. jurisdictions.
The Company provides reserves for potential payments of taxes to various tax authorities related to uncertain tax positions. Amounts recognized are based on a determination of whether a tax benefit taken by the Company in its tax filings or positions is “more likely than not” to be sustained on audit. The amount associated with uncertain tax positions are recorded as a component of income tax expense. As of September 30, 2023, the Company has accrued uncertain tax positions of approximately $1.0 million related to the EnvisionTEC acquisition. The amounts relate to U.S. state and foreign tax positions. Included in the balance of unrecognized tax benefits as of September 30, 2023 are amounts that, if recognized, would impact the effective tax rate. As of December 31, 2022, the Company recorded a liability of $1.0 million for uncertain tax positions acquired in various acquisitions
during 2021. As of December 31, 2022, the Company had a balance in accrued interest and penalties related to uncertain tax positions of $0.2 million.
