In November 2015, the FASB issued amended guidance which requires all deferred income tax assets and liabilities to be presented as noncurrent on the balance sheet. This amended guidance is effective beginning January 1, 2017, and may be applied retrospectively or prospectively, with early adoption permitted. We have early adopted this amended guidance and applied the presentation prospectively as of December 31, 2015. For the year ended December 31, 2014, there were $107.1 of current deferred tax assets included within Other current assets and $5.4 of current deferred tax liabilities included within Accrued liabilities, which would be classified as noncurrent under the amended guidance.
We evaluate the realizability of our deferred tax assets on a quarterly basis. The realization of our deferred tax assets is primarily dependent on future earnings. The amount of the deferred tax assets considered realizable could be reduced or increased in the near future if estimates of future taxable income are lower or greater than anticipated. A valuation allowance is established when it is “more likely than not” that all or a portion of deferred tax assets will not be realized. In circumstances where there is negative evidence, establishment of a valuation allowance is considered. The factors used in assessing valuation allowances include all available evidence, such as past operating results, estimates of future taxable income and the feasibility of tax planning strategies. We believe that cumulative losses in the most recent three-year period represent significant negative evidence, and as a result, we determined that certain of our deferred tax assets required the establishment of a valuation allowance. The deferred tax assets for which an allowance was recognized relate primarily to state and foreign tax loss carryforwards.
The change in the valuation allowance is listed below.

In 2015, amounts reversed to costs and expenses primarily related to the decrease in valuation allowances in Continental Europe for existing deferred tax assets. The amounts reversed to gross tax assets and other accounts relate primarily to the effect of foreign currency translation.
In 2014, the net decrease was primarily related to a reversal of a valuation allowance for a deferred tax asset of $124.8, where we believe it is now "more likely than not" that the corresponding tax losses will be utilized over an extended period of time, based on implementing an internal financing tax action plan. This was partially offset by the establishment of a valuation allowance of $57.2, where we believe it is no longer "more likely than not" that the corresponding tax losses will be utilized, based on forecasted income not exceeding historical cumulative losses. The amounts charged to gross tax assets and other accounts relate primarily
