With few exceptions, the major jurisdictions subject to examination by the relevant taxable authorities, and open tax years, stated as the Company's fiscal years, are as follows:



Jurisdiction	Open Tax Years
U.S. Federal	2014	-	2017
U.S. States	2013	-	2017

Since net operating loss carryovers are subject to audit based on the year in which they are utilized, all of the Company’s net operating losses generated in the past are open to adjustment to the Internal Revenue Service or state tax authorities (some states have shorter carryover periods).

On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (the “Act”). The Act significantly revises the future ongoing U.S. corporate income tax by, among other things, lowering the U.S. corporate federal income tax rate from 34% to 21% effective January 1, 2018. As a result, a blended federal rate of 30.75% is required for the current year income tax expense. Further, the Company is required to re-measure, through income tax expense, its deferred tax assets and liabilities using the enacted rate at which the items are expected to be recovered or settled. During the third quarter, the Company recorded provisional amounts as a result of the re-measurement of the Company’s net deferred tax asset did not result in income tax expense due to the Company’s full valuation allowance position.

Total net deferred tax assets decreased by $15.1 million, which includes a reclassification of the federal alternative minimum tax (“AMT”) credit to long term receivable. As of March 31, 2018, the Company had net deferred tax assets of approximately $37.1 million before a valuation allowance of $37.1 million.

The final transition impacts of the Act may differ from the above estimate, due to, among other things, changes in interpretations of the Act, any legislative action to address questions that arise because of the Act, any changes in accounting standards for income taxes or related interpretations in response to the Act, or any updates or changes to estimates the Company has utilized to calculate the transition impacts, including impacts from changes to current year earnings estimates. The Securities Exchange Commission has issued guidance that allows for a measurement period of up to one year after the enactment date of the Act to finalize the recording of the related tax impacts. We currently anticipate finalizing and recording any resulting adjustments in the period the Company files the fiscal year ending March 31, 2018 income tax return.

As of March 31, 2018, the Company has $697,000 of AMT credit carryforward, which does not expire and is now carried as a tax receivable since, under new federal tax law, the Company expects to recover the entire amount by 2022 via a tax refund. Previously, there was a valuation allowance against the entire AMT credit carryforward. In the third quarter, the Company reversed the portion of the valuation allowance related to the AMT credit carryforward, which resulted in a discrete tax benefit of $697,000. The total refundable amount is not reduced by the sequestration rate since the fiscal year 2018 Consolidated Federal return is not expected to be filed until the third quarter of fiscal year 2019, and the sequestration rate for fiscal year 2019 is not yet available as of fiscal year 2018.
