The sum of the tax effects as of the balance sheet date of the amount of excesses of tax deductions over gross income in a year which cannot be used on the tax returns in the current year but can be carried forward to reduce taxable income or income taxes payable in a future year, for which there must be sufficient tax-basis income to utilize a portion or all of the carryforward amount to realize the deferred tax asset. Also includes the cumulative amount of future tax effects arising from the unused tax credit carryforward that cannot be utilized on the tax return during a year that may be carried forward to reduce taxable income or taxes payable in a future year; a tax credit carryforward is the amount by which tax credits available for utilization exceed statutory limitations.
