Income Taxes	3. Income Taxes During the three and six month periods ended March 31, 2018 income taxes were impacted relative to the prior year period by the Tax Cuts and Jobs Act (“the Act”), which was enacted into law on December 22, 2017.

The Act includes significant changes to the U.S. corporate income tax system which reduces the U.S. federal corporate tax rate from 35.0% to 21.0% as of January 1, 2018. The decrease in the U.S. federal corporate tax rate from 35.0% to 21.0% results in a blended statutory tax rate of 24.5% for the fiscal year ending September 30, 2018. The Act also eliminates for NOLs the previous carryback period of two years and permits an indefinite carryforward period.
