Income Tax Uncertainties Policy We apply a more-likely-than-not threshold to the recognition and derecognition of uncertain tax positions. Accordingly we recognize the amount of tax benefit that has a greater than 50 percent likelihood of being ultimately realized upon settlement. Future changes in judgment related to the expected ultimate resolution of uncertain tax positions will affect earnings in the quarter of such change.
