Note 5. Income Taxes

We make estimates and judgments in determining our income tax expense for financial reporting purposes. These estimates and judgments occur in the calculation of certain tax assets and liabilities that arise from differences in the timing and recognition of revenue and expense for tax and financial reporting purposes. Significant judgment is required in estimating valuation allowances, and in making this determination we consider all available positive and negative evidence and make certain assumptions. The realization of a deferred tax asset ultimately depends on the existence of sufficient taxable income in the applicable carryback or carryforward periods. In our assessment, we consider the nature, frequency, and severity of current
and cumulative losses, as well as historical and forecasted financial results, the overall business environment, our industry’s historic cyclicality, the reversal of existing deferred tax assets and liabilities, and tax planning strategies.

We assess the valuation allowance recorded on our deferred tax assets on a quarterly basis, which was $59.2 million at December 31, 2022. This valuation allowance relates primarily to our Louisiana net deferred tax assets of $55.4 million, as well as our Alabama net deferred tax assets and certain Mississippi tax credits totaling $3.8 million. We have concluded that the benefits of such deferred tax assets are not more likely than not to be realized due to lack of sufficient taxable income to fully realize the benefits of such deferred tax assets.

We evaluate our estimated annual effective income tax rate based on current and forecasted business results and enacted tax laws on a quarterly basis and apply this tax rate to our ordinary income or loss to calculate our estimated tax liability or benefit. Our income taxes are based on an estimated combined federal and state statutory rate of approximately 25% in 2023 and 2022. Our effective tax rate for the three months ended March 31, 2023 was slightly lower than our estimated statutory rate primarily due to excess stock compensation deductions that were recorded discretely in the quarter. Our effective tax rate for the three months ended March 31, 2022 was higher than our estimated statutory rate due to the release of a portion of the valuation allowance on our deferred tax assets combined with the net loss for the period.
