- Definition

The tax effects of uncertain tax positions taken or expected to be taken in income tax returns are recognized only if they are “more likely-than-not” to be sustained on examination by the taxing authorities, based on the technical merits as of the reporting date. The tax benefits recognized in the financial statements from such positions are measured based on the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate settlement. This tag refers to that fifty percent likelihood.
