On December 22, 2017, the Tax Cuts and Jobs Act ("TCJA") was signed into law. The TCJA significantly revises the U.S. corporate income tax by, among other things, lowering corporate income tax rates, implementing a hybrid territorial tax system, and imposing a mandatory one-time repatriation tax on foreign cash and earnings.

As a result of the TCJA, we remeasured certain deferred tax assets and liabilities at the lower rates and recorded approximately $87.0 million of tax benefits for the six months ended March 31, 2018, which also reflected an expense of $10.0 million for the three months ended March 31, 2018 as we revised our estimates of the timing and amounts of the temporary differences. Additionally, we recorded a $2.0 million provision for the deemed repatriation of foreign cash and earnings for the six months ended March 31, 2018, which also reflected a benefit of $12.0 million for the three months ended March 31, 2018 as we revised our estimates of foreign earnings and profits related to the mandatory repatriation tax.

The provisional amounts above were based upon the estimates of (i) temporary differences at the end of the upcoming tax year, (ii) the timing the temporary differences are expected to reverse, (iii) foreign earnings and profits, and (iv) foreign income taxes. The assessment is incomplete as of March 31, 2018. As our assessment is ongoing, these amounts may materially change as we revise our assumptions and estimates based on new information available to us, changes in our interpretations, additional guidance to be issued, and actions we may take as a result of the TCJA. We are still evaluating the full impact of other provisions of the TCJA, which may materially increase or decrease our income tax provision. The assessment is expected to be completed no later than the first quarter of fiscal year 2019.

In addition, as more fully described in Note 4, in connection with the impairment charge of SRS's goodwill, we recognized a tax benefit of $8.5 million related to the portion of deductible goodwill in Brazil for the three and six months ended March 31, 2018.
