Deferred taxes are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized. Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates on the date of the enactment.

In evaluating the ultimate realization of deferred income tax assets, management considers whether it is more likely than not that the deferred income tax assets will be realized. Management establishes a valuation allowance if it is more likely than not that all or a portion of the deferred income tax assets will not be utilized. The ultimate realization of deferred income tax assets is dependent on the generation of future taxable income, which must occur prior to the expiration of the net operating loss carryforwards.
