Based on our evaluation of current and anticipated future taxable income, we believe it is more likely than not that insufficient taxable income will be generated to realize the net deferred tax assets, and accordingly, a valuation allowance has been set against these net deferred tax assets. The $0.3 million deferred tax asset is recorded in other assets on the balance sheet.
We do not provide for U.S. income taxes for any undistributed earnings of our foreign subsidiaries, as we consider these to be permanently reinvested in the operations of such subsidiaries and have a cumulative foreign loss. At December 31, 2025 and 2024, these undistributed earnings totaled $3.6 million and $6.5 million, respectively. If any earnings were distributed, some countries may impose withholding taxes. However, due to our overall deficit in foreign cumulative earnings and its U.S. loss position, we do not believe a material net unrecognized U.S. deferred tax liability exists.
ASC 740 Income Taxes provides that the tax effects from an uncertain tax position can be recognized in our financial statements only if the position is more-likely-than-not of being sustained on audit, based on the technical merits of the position. Tax positions that meet the recognition threshold are reported at the largest amount that is more-likely-than-not to be realized. This determination requires a high degree of judgment and estimation. We periodically analyze and adjust amounts recorded for the Company’s uncertain tax positions, as events occur to warrant adjustment, such as when the statutory period for assessing tax on a given tax return or period expires or if tax authorities provide administrative guidance or a decision is rendered in the courts. The Company does not reasonably expect the total amount of uncertain tax positions to significantly increase or decrease within the next 12 months. As of December 31, 2025, our uncertain tax positions were not significant for income tax purposes.

About Income Taxes Disclosures
The income tax disclosure reveals how much a company actually pays in taxes versus what the statutory rate would predict. Analysts focus on the effective tax rate (ETR) reconciliation, which breaks down every item driving the gap between the 21% federal rate and the company's reported ETR — including R&D credits, foreign rate differentials, and state taxes. Deferred tax assets (DTAs) and their valuation allowances signal management's confidence in future profitability: a rising allowance suggests the company doubts it can use accumulated tax benefits. Uncertain tax benefit (UTB) reserves quantify exposure to IRS challenges on aggressive positions.
Key signals to watch: sudden ETR drops without clear operational reasons, large increases in valuation allowances, growing UTB balances, and significant unremitted foreign earnings. Post-TCJA, pay attention to GILTI and BEAT provisions that affect multinational tax structures. Compare the cash taxes paid (from the cash flow statement) against the income tax provision to gauge earnings quality.
