The tax effect as of the balance sheet date of the amount of the estimated future tax deductions arising from miscellaneous accruals, which can only be deducted for tax purposes when losses related to miscellaneous accruals are actually incurred, and which can only be realized if sufficient tax-basis income is generated in future periods to enable the deduction to be taken.
