In accordance with the Financial Accounting Standards Board Accounting Standards Codification (‘ASC”) 740, we evaluate our deferred taxes quarterly to determine if adjustments to our valuation allowance are required based on the consideration of available positive and negative evidence using a “more likely than not” standard with respect to whether deferred tax assets will be realized. Our evaluation considers, among other factors, our historical operating results, our expectation of future results of operations, the duration of applicable statuary carryforward periods and conditions of the healthcare industry. The ultimate realization of our deferred tax assets depends primarily on our ability to generate future taxable income during the periods in which the related temporary differences in the financial basis and the tax basis of the assets become deductible. The value of our deferred tax assets will depend on applicable income tax rates.

The Tax Cuts and Jobs Act (“TCJA”) was enacted on December 22, 2017. Under ASC 740, the impact of changes in tax law must be recorded in the financial statements in the reporting period that included the date of enactment. In addition, in conjunction with the TCJA, on December 22, 2017, the SEC staff issued Staff Accounting Bulletin No. 118, Income Tax Accounting Implications of the Tax Cuts and Jobs Act (“SAB 118”), which provides guidance on accounting for the tax effects of the TCJA. SAB 118 allows for recording certain effects of the TCJA as “provisional” during a one-year measurement period, which for the Company ended in the second quarter of fiscal 2019.

At June 30, 2019, consistent with the above process, we evaluated the need for a valuation against our deferred tax assets and determined that it was more likely than not that none of our deferred tax assets would be realized. As a result, in accordance with ASC 740, we recognized a valuation allowance of $8,625 against the deferred tax asset so that there is no net long-term deferred income tax asset or liability at June 30, 2019. We conducted our evaluation by considering available positive and negative evidence to determine our ability to realize our deferred tax assets. In our evaluation, we gave more significant weight to evidence that was objective in nature as compared to subjective evidence. Also, more significant weight was given to evidence that directly related to our current financial performance as compared to less current evidence and future plans.

The principal negative evidence that led us to determine at June 30, 2019 that all the deferred tax assets should have full valuation allowances was the three-year cumulative pre-tax loss from continuing operations as well as the underlying negative business conditions for rural healthcare businesses in which our Healthcare Services Segment businesses operate.

For Federal income tax purposes, at June 30, 2019, the Company had approximately $16,700 of estimated net operating loss carry-forwards available for use in future years subject to the limitations of the provisions of Internal Revenue Code Section 382. These net operating loss carryforwards expire primarily in fiscal 2023 through fiscal 2038; however, with the enactment of the TCJA on December 22, 2017, federal net operating loss carryforwards generated in taxable years beginning after December 31, 2017 now have no expiration date. The Company’s returns for the periods prior to the fiscal year ended June 30, 2016 are no longer subject to potential federal and state income tax examination.

We recorded a discrete net tax benefit of $0 during the year ended June 30, 2018 related to provisional amounts under SAB 118 for the remeasurement of U.S. deferred tax assets and liabilities due to the Federal tax rate reduction to 21%. No net tax benefit was recorded due to the Company’s full valuation allowance position. The $296 of tax benefit recorded for the year ended June 30, 2018 was due to the release of the valuation allowance on the Company’s Alternative Minimum Tax (“AMT”) Credit, which became refundable under the TCJA. The final amount of AMT Credit valuation allowance release at June 30, 2018 was $305 due to adjustments made from the final June 30, 2017 tax return filing during the fourth quarter ended fiscal 2018. We also recorded an additional $40 of tax benefit at June 30, 2018 unrelated to the remeasurement of U. S. deferred tax assets and liabilities. No changes were recorded to this provisional estimate during the year ended June 30, 2019. Pursuant to the requirements of SAB 118 as discussed above the Company has completed its accounting for the TCJA for the second quarter ended fiscal 2019.
