(1) State taxes in Oregon made up the majority (greater than 50%) of the tax effect in this category for 2025 - 2023
The income tax expense recorded for 2025 and 2024 primarily relates to operations in China and Finland, offset by income tax reserve reversals.
The tax effects of temporary differences that give rise to significant portions of the deferred tax assets and deferred tax liabilities are as follows (in thousands):

Net deferred tax assets are included in Other assets, net in our Consolidated Balance Sheets.
In evaluating our valuation allowance, we consider all available positive and negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax planning strategies, and recent financial performance. Due to uncertainty with respect to ultimate realizability of deferred tax assets, we have provided a full valuation allowance against the U.S. deferred tax assets and a partial valuation allowance against the China deferred tax assets. The net change in the total valuation allowance for the years ended December 31, 2025, 2024 and 2023 were increases of $5.5 million, $9.0 million and $7.7 million, respectively.
At December 31, 2025, we had U.S. and state net operating loss (NOL) carryforwards of, $205.5 million, and $60.1 million, respectively. These carryforwards will expire from 2026 to 2045 if not used by us to reduce taxable income in future periods. We have U.S. research and development credit carryforwards of $11.0 million. These carryforwards will expire from 2026 to 2045 if not used by us to reduce income taxes payable in future periods.
Utilization of NOL carryforwards, credit carryforwards and certain deductions have been subject to annual limitations due to ownership change limitations provided by the Internal Revenue Code of 1986, as amended. We have had three "change in ownership" events that limit the utilization of NOL carryforwards, which occurred twice in August of 2000 and once in January of 2001, and resulted in NOL carryforward limitations totaling $0.5 million. Additional limitations on the use of these tax attributes could occur in the event of possible disputes arising in examination from various taxing authorities.

| Balance at December 31, 2025 | $ | 8,716 | |
At December 31, 2025, we had $2.7 million of unrecognized tax benefits (excluding interest and penalties) in Non-Current Income Taxes Payable and $6.0 million of unrecognized tax benefits as an offset to our long-term deferred tax assets embedded in Other Assets, Net on the accompanying Consolidated Balance Sheets. Of our unrecognized tax benefits, $2.7 million, if recognized, would impact the effective tax rate. At December 31, 2024, we had $2.7 million of unrecognized tax benefits (excluding interest and penalties) in Non-Current Income Taxes Payable and $5.8 million of unrecognized tax benefits as an offset to our long-term deferred tax assets embedded in Other Assets, Net on the accompanying Consolidated Balance Sheets.
We recognize interest and penalties related to unrecognized tax benefits as a component of income tax expense. We recognized a net increase (decrease) in penalties and interest during the years ended December 31, 2025, and 2024 and 2023, of $0.1 million, $0.2 million, and $(1.0) million, respectively. At December 31, 2025, 2024, and 2023, interest and penalties associated with unrecognized tax benefits were $1.2 million, $1.1 million, and $0.9 million, respectively.
At December 31, 2025, our tax years 2022 through 2025, 2021 through 2025, and 2015 through 2025, remain open for examination in the federal, state and foreign jurisdictions, respectively. However, to the extent allowed by law, the taxing authorities may have the right to examine prior periods where net operating losses and credits were generated and carried forward, and to make adjustments up to the net operating loss and credit carryforward amounts. We are not currently under federal, state, or foreign tax examination.
