Income Taxes
NOTE 5 Income Taxes
The Corporation’s gross deferred tax assets of approximately $33 million consist of approximately $20 million in federal net operating loss and tax credit carryforwards, $6 million in state net operating loss carryforwards, and $7 million resulting from temporary differences between financial and tax reporting. The federal net operating loss and tax credit carryforwards have a life expectancy of twenty years. The state net operating loss carryforwards have a life expectancy, depending on the state where a loss was incurred, between five and twenty years. If the Corporation, after considering future negative and positive evidence regarding the realization of deferred tax assets, determines that a lesser valuation allowance is warranted, it would record a reduction to income tax expense and the valuation allowance in the period of determination.
