5.5 Reduction of a Valuation Allowance When Negative Evidence Is No Longer Present
When an entity concludes that negative evidence (as discussed in ASC 740-10-30-21) exists
            and that realization of all or a portion of its DTA as of that date is not more likely
            than not, the entity would recognize a valuation allowance to reduce its DTA to an
            amount that is more likely than not to be realized. However, circumstances may change
            over time such that in a subsequent year, the negative evidence discussed in ASC
            740-10-30-21 is no longer present.
        If an entity has returned to profitability for a sustained period, the
            entity should assume, in the absence of evidence to the contrary, that favorable
            operations or conditions will continue in the future. Further, as discussed in Section 5.3.2.2.1, unless the
            facts and circumstances dictate otherwise, an entity should not limit the estimate of
            future income to (1) a specific period (e.g., the period over which it measures
            cumulative losses in recent periods) or (2) general uncertainties. For example, it would
            be inappropriate to project taxable income for only three years and assume that taxable
            income beyond three years would be zero solely on the basis of the uncertainty in
            projecting taxable income beyond three years (such a projection would be particularly
            inappropriate if income is projected in connection with other financial statement
            assertions, such as those about impairment tests). Therefore, the valuation allowance
            provided in prior years for which negative evidence was present should be eliminated in
            the period in which the negative evidence ceases to exist.
