Answer:
$2,000 decrease in income tax expense
Step-by-step explanation:
Two years ago Aggre recorded a $20,000 income tax expenses, that means that they lowered their income tax by $20,000 due to an uncertain tax position (UTP).
First we must understand what a UTP is: a tax position that is not 100% certain to turn out that way, but is considered more likely than not, therefore it can be recognized in the financial statements until things get clear.
Finally two years later, Aggre was right and the tax benefit was even larger, equal to $22,000. Now it must recognize the portion that was not recognized before = $22,000 - $20,000 = $2,000 decrease in income tax expense
