In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. A valuation allowance is required to be recognized for the portion of the deferred tax asset that will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. As of December 31, 2025, based upon the level of historical taxable income and projections for future taxable income over the periods in which the deferred tax assets are deductible, management expects to realize the benefits of these deductible differences.

At December 31, 2025 and December 31, 2024, the Company had a federal net operating loss carryforward of $494,000 and $593,000, respectively, that does not expire. The Company is limited to the amount of the net operating loss carryforward that it can deduct each year under Section 382 of the Internal Revenue Code. Due to sufficient earnings history and other positive evidence, management hasnot recorded a valuation allowance on the federal net operating loss carryforward as of December 31, 2025 and December 31, 2024. At December 31, 2025, the Company had a federal tax credit carryforward of $40.6 million that expires in 2044. Due to sufficient earnings history and other positive evidence, management has not recorded a valuation allowance on the tax credit carryforward as of December 31, 2025.

As of December 31, 2025 and December 31, 2024, the Company had no unrecognized tax benefits. While the Company had no unrecognized tax benefits as of December 31, 2025 and 2024, in the event recording interest and penalties is necessary, they will be recorded as part of income tax expense.

The Company has qualified under provisions of the Internal Revenue Code to compute income taxes after deductions of additions to the bad debt reserves when it was registered as a Savings Bank. At December 31, 2025, the Company had a taxable temporary difference of approximately $2.8 million that arose before 1988 (base-year amount). In accordance with FASB ASC 740, an estimated deferred tax liability of $588,000 has not been recognized for the temporary difference. Management does not expect this temporary difference to reverse in the foreseeable future.

The Company and its Bank subsidiary file a United States consolidated federal income tax return, Oregon State and local income tax returns, and Idaho State tax return. The tax years subject to examination by the Internal Revenue Service are the years ended December 31, 2025, 2024, 2023 and 2022.
