The Company's significant accounting policies are described in Note 3, "Summary of Significant Accounting Policies," in the Company's Annual Report on Form 10-K for the fiscal year ended June 30, 2018. There have been no material changes in these policies or their application.

Reclassifications

Certain prior period amounts have been reclassified to conform to the current period presentation for comparative purposes.

Net Loss Per Common Share

The Company calculates basic loss per common share by dividing net loss by the weighted average number of common shares outstanding during the periods. Diluted loss per common share includes the impact from all dilutive potential common shares relating to outstanding convertible securities.

For the three months ended March 31, 2019 and 2018, basic and diluted weighted-average common shares outstanding were 50,769,673 and 25,112,349, respectively. For the nine months ended March 31, 2019 and 2018, basic and diluted weighted-average common shares outstanding were 41,054,334 and 25,142,039, respectively. The Company incurred a net loss for the three and nine months ended March 31, 2019 and 2018, and therefore, basic and diluted loss per share for the periods are the same because the inclusion of potential common equivalent shares were excluded from diluted weighted-average common shares outstanding during the period, as the inclusion of such shares would be anti-dilutive. The total potentially dilutive common shares outstanding at March 31, 2019 and 2018, excluded from diluted weighted-average common shares outstanding, which include common shares underlying outstanding convertible debt, stock options and warrants, were 5,923,106 and 17,987,632, respectively.

Income Taxes

We follow the liability method of accounting for income taxes under which deferred tax assets and liabilities are recognized for the future tax consequences of (i) temporary differences between the tax basis of assets and liabilities and their reported amounts in the consolidated financial statements and (ii) operating loss and tax credit carry-forwards for tax purposes. Deferred tax assets are reduced by a valuation allowance when, based upon management’s estimates, it is more likely than not that a portion of the deferred tax assets will not be realized in a future period. We recognized a full valuation allowance as of March 31, 2019 and June 30, 2018 and have not recognized any tax provision or benefit for any of the periods presented. We review our tax positions quarterly for tax uncertainties. We did not have any uncertain tax positions as of March 31, 2019 or June 30, 2018. 

In December 2017, the United States (“U.S.”) enacted the Tax Cuts and Jobs Act (the “2017 Act”), which changes existing U.S. tax law and includes various provisions that are expected to affect companies. Among other things, the 2017 Act reduces the top U.S. corporate income tax rate from 35.0% to 21.0%, and makes changes to certain other business-related exclusions, deductions and credits. The Company has assessed the impact of the tax bill on the financial statements as of June 30, 2018 and has determined it to be immaterial.   Due to the Company's full valuation allowance, the tax effects of any changes are not expected to have a material impact on our consolidated financial statements.
