The Company monitors the realizability of deferred tax assets, taking into account all relevant factors at each reporting period. As of March 31, 2025, the Company had a valuation allowance of $1.2 million, which related to Arizona research and development credits and capital loss carryforwards. As of March 31, 2024, the Company had a valuation allowance of $1.2 million, which related to Arizona research and development credits, California alternative minimum tax credits, and capital loss carryforwards. Pursuant to provisions under the Inflation Reduction Act, the Company purchased $17.4 million of transferable federal tax credits during the fiscal year ended March 31, 2025, from various counterparties. In connection with the purchase, the Company paid $16.1 million for tax credits related to fiscal year March 31, 2025, which were purchased at negotiated discounts, resulting in an income tax benefit of $1.3 million recorded during the fiscal year ended March 31, 2025. The Company is also committed to paying $3.2 million for additional transferable tax credits placed in service as of March 31, 2025, and paying $12.3 million for transferable tax credits as future projects are placed in service, with the final project expected to be placed in service in fiscal 2026. As of March 31, 2025, the Company had net operating loss, or NOL, carryforwards for state tax purposes of $4.2 million. Portions of the NOL carryforwards will expire at various dates beginning in the tax year ending March 31, 2042. As of March 31, 2025, the Company had research and development tax credit carryforwards for state tax purposes of $10.0 million. The California state research and development tax credit carryforwards do not expire. The other state research and development tax credit carryforwards will expire at various dates beginning in the year ending March 31, 2033. Based on an assessment of the Company’s historical ownership changes through March 31, 2025, the Company does not anticipate a current limitation on the tax attributes. As of March 31, 2025 and 2024, the Company had unrecognized tax benefits, or UTBs, of $12.0 million and $9.3 million, respectively. If realized, $11.8 million would impact the effective tax rate while the remainder would reduce deferred tax assets subject to a full valuation allowance. The Company does not expect any material changes to its UTBs within the next 12 months. A reconciliation of the beginning and ending balances for gross UTBs is as follows (in thousands):
| Fiscal Year Ended March 31,
