The preparation of financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities as at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Those estimates and assumptions include estimates for depreciable lives of property, plant and equipment, intangible assets, analysis of impairments of recorded intangible assets, accruals for potential liabilities and assumptions made in calculating the fair value of stock-based compensation and other stock instruments.

The Company is registered for the Canadian federal and provincial goods and services taxes. As such, the Company is obligated to collect, and is entitled to claim sales taxes paid on its expenses and capital expenditures incurred in Canada. As at November 30, 2018 and February 28, 2018, the computed recoverable sales taxes amounted to $63,709 and $177,903, respectively.

The Company computes net loss per share in accordance with FASB ASC 260, Earnings Per Share. Basic earnings (loss) per share is computed by dividing the net income (loss) applicable to common stockholders by the weighted average number of shares of common stock outstanding during the year. The Company includes common stock issuable in its calculation. Diluted earnings (loss) per share is computed by dividing the net income (loss) applicable to common stockholders by the weighted average number of common shares outstanding plus the number of additional common shares that would have been outstanding if all dilutive potential common shares had been issued, using the treasury stock method. Potential common shares are excluded from the computation if their effect is antidilutive.

For the three and nine months ended November 30, 2018 and 2017, the calculations of basic and diluted loss per share are the same as potential dilutive securities would have an antidilutive effect. The potentially dilutive securities consisted of 2,345,957 outstanding warrants, 99,498 restricted stock units and 1,000,000 shares issuable to our CEO per his employment agreement (Note 6) as at November 30, 2018 (2017 – 2,684,582, 34,102 and 1,000,000, respectively).

In February 2018, the FASB issued ASU 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, which permits entities to reclassify the disproportionate income tax effects of the Tax Reform Act on items within accumulated other comprehensive income (loss) ("AOCI") to retained earnings. These disproportionate income tax effect items are referred to as "stranded tax effects." Amendments in this update only relate to the reclassification of the income tax effects of the Tax Reform Act. Other accounting guidance that requires the effect of changes in tax laws or rates to be included in net income from continuing operations is not affected by this update. ASU 2018-02 should be applied either in the period of adoption or retrospectively to each period in which the effect of the change in the U.S. federal corporate income tax rate in the Tax Reform Act is recognized. ASU 2018-02 is applicable beginning March 1, 2019. The Company does not expect that ASU 2018-02 will have an impact on its consolidated financial statements.

In June 2018, the FASB issued ASU 2018-07, Compensation – Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting. The amendments in this Update expand the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees. An entity should apply the requirements of Topic 718 to nonemployee awards except for specific guidance on inputs to an option pricing model and the attribution of cost (that is, the period of time over which share-based payment awards vest and the pattern of cost recognition over that period). The amendments specify that Topic 718 applies to all share-based payment transactions in which a grantor acquires goods or services to be used or consumed in a grantor’s own operations by issuing share-based payment awards. The amendments also clarify that Topic 718 does not apply to share-based payments used to effectively provide (1) financing to the issuer or (2) awards granted in conjunction with selling goods or services to customers as part of a contract accounted for under Topic 606, Revenue from Contracts with Customers. The amendments in this Update are effective for public entities for fiscal years beginning after December 15, 2018, including interim periods within that fiscal year. The Company does not expect that ASU 2018-07 will have an impact on its consolidated financial statements.

In July 2018, the FASB issued ASU 2018-09, Codification Improvements, which clarify certain amendments to guidance that may have been incorrectly or inconsistently applied by certain entities and includes Amendments to Subtopic 718-740, Compensation – Stock Compensation – Income Taxes. The guidance in paragraph 718-740-35-2, as amended by the amendments in ASU 2016-09, Compensation – Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, is unclear on whether an entity should recognize excess tax benefits (or tax deficiencies) for compensation expense that is taken on the entity’s tax return. The amendment to paragraph 718-740-35-2 in this Update clarifies that an entity should recognize excess tax benefits in the period in which the amount of deduction is determined. The amendments in this Update are effective for public entities for fiscal years beginning after December 15, 2018, including interim periods within that fiscal year. The Company does not expect that this update will have an impact on its consolidated financial statements.
