Business Combinations

Business combinations are accounted for using the acquisition method of accounting. Acquisition cost is measured as the aggregate of the fair value at the date of acquisition of the assets given, equity instruments issued, or liabilities incurred or assumed. Acquisition related costs are expensed as incurred (except for those costs arising on the issue of equity instruments which are recognized directly in equity). Identifiable assets acquired and liabilities and contingent liabilities assumed in a business combination are measured at fair value on the acquisition date. Goodwill is measured as the excess of the acquisition cost and the amount of any non-controlling interest, over the fair value of the identifiable net assets acquired.

Patents

Patents

Capitalized patent costs represent legal costs incurred to establish patents and a portion of the acquisition price paid attributed to patents upon the acquisition of NGIO in August 2003 and the acquisition of NGDx in January 2017. When patents reach a mature stage, any associated legal costs are comprised mostly of maintenance fees and costs of national applications and are expensed as incurred. Capitalized patent costs are amortized on a straight-line basis over the remaining life of the patent. As patents are abandoned, the net book value of the patent is written off.

In-Process Research and Development

In-Process Research and Development

The costs of in-process research and development (“IPR&D”), related to the Company’s business combination with NGDx, were recorded at fair value on the acquisition date. IPR&D intangible assets are considered indefinite-lived intangible assets until completion or abandonment of the associated research and development efforts. IPR&D is not amortized, but is reviewed for impairment at least annually, or when events or changes in the business environment indicate the carrying value may be impaired. The Company also acquired licenses to operate pharmacies which were recorded at cost. They are evaluated annually for possible impairment. Management determined that as of July 31, 2020, the IPR&D and licenses are not impaired.

Debt Discount

Debt Discount

The Company issued certain convertible notes that have certain embedded derivatives and/or required bifurcation. In connection with these features, the Company has recorded a discount to the debt for these features that will be accreted to the face value of the note under the effective interest method over the term of the note. The amount of debt discount incurred during the years ended July 31, 2020 and 2019, was $2,749,107 and $5,100,421, respectively. The Company recognized approximately $4,415,377 and $3,121,569, of related interest expense for the years ended July 31, 2020 and 2019, respectively.

Research and Development Costs

Research and Development Costs

Expenditures for research and development are expensed as incurred and include, among other costs, those related to the production of experimental drugs, including payroll costs, and amounts incurred for conducting clinical trials. Amounts expected to be received from governments under research and development tax credit arrangements are offset against current research and development expense.

Inventories

Inventories

Inventories, which consist of both raw materials and finished goods, is valued at the lower of cost or net realizable value. Inventory costs are comprised primarily of product, labor, freight and duty. The Company writes down inventory for estimated obsolescence equal to the difference between the cost of inventory and the estimated market value based upon assumptions about future demand and market conditions.

Stock-Based Compensation

Stock-Based Compensation

The Company follows FASB ASC Topic 718 which requires that new, modified and unvested share-based payment transactions with employees, such as grants of stock options and restricted stock, be recognized in the consolidated financial statements based on their fair value at the grant date and recognized as compensation expense over their vesting periods, which typically conform to the performance period. The Company estimates the fair value of stock options as of the date of grant using the Black-Scholes option pricing model and restricted stock based on the quoted market price or the value of the services provided, whichever is more readily determinable. The Company also follows the guidance in FASB ASC Topic 505 for equity based payments to non-employees for equity instruments issued to consultants and other non-employees.

Comprehensive Loss

Comprehensive Loss

Other comprehensive income/(loss), which includes only foreign currency translation adjustments, is shown in the consolidated statements of operations and comprehensive loss and in the consolidated statements of changes in stockholders’ deficiency.

Fair Value of Financial Instruments

Fair Value of Financial Instruments

Fair value is defined under FASB ASC Topic 820 as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or the most advantageous market for an asset or liability in an orderly transaction between participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The standard describes a fair value hierarchy based on the levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value. The levels are as follows:

•

Level 1 - Quoted prices in active markets for identical assets or liabilities

•

Level 2 - Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or corroborated by observable market data for substantially the full term of the assets or liabilities

•

Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the value of the assets or liabilities

The following is a listing of the Company’s liabilities required to be measured at fair value on a recurring basis and where they are classified within the fair value hierarchy as of July 31, 2020 and July 31, 2019:

	July 31, 2020
	Level 1		Level 2		Level 3		Total
Derivative liability	$	—	$	—	$	1,316,757	$	1,316,757
Total	$	—	$	—	$	1,316,757	$	1,316,757

	July 31, 2019
	Level 1		Level 2		Level 3		Total
Derivative liability	$	—	$	—	$	7,820,282	$	7,820,282
Total	$	—	$	—	$	7,820,282	$	7,820,282

Redeemable Non-Controlling Interest

Redeemable Non-Controlling Interest

As a result of the acquisition of Regentys, which had redeemable convertible preferred stock on its balance sheet classified as a mezzanine instrument outside of the its equity accounts, such amounts are reclassified as redeemable non-controlling interest as the carrying value determined by the purchase price allocation at the time of the acquisition of Regentys.

Recently Issued Accounting Standards

Recently Issued Accounting Standards

In February 2018, the FASB issued ASU 2018-02, Income Statement – Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, which was issued to address the income tax accounting treatment of the stranded tax effects within other comprehensive income due to the prohibition of backward tracing due to an income tax rate change that was initially recorded in other comprehensive income. This issue came about from the enactment of the TCJA on December 22, 2017 that changed the Company’s federal income tax rate from 35% to 21% effective January 1, 2018 and the establishment of a territorial-style system for taxing foreign-source income of domestic multinational corporations. In December 2017, the SEC issued Staff Accounting Bulletin No. 118, Income Tax Accounting Implications of the Act (“SAB118”), which allows us to record provisional amounts during a measurement period not to extend beyond one year of the enactment. The Company remeasured its deferred tax assets and liabilities as of July 31, 2018, applying the reduced corporate income tax rate and recorded a provisional decrease to the deferred tax assets of $31,876,520, with a corresponding adjustment to the valuation allowance. In the fourth quarter of fiscal year ended July 31, 2019, we completed our analysis to determine the effect of the Tax Act and there were no material adjustments as of July 31, 2019.

In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”) and also issued subsequent amendments to the initial guidance: ASU 2018-19, ASU 2019-04, and ASU 2019-05 (collectively, “Topic 326”). Topic 326 requires measurement and recognition of expected credit losses for financial assets held. The Company will be required to adopt this ASU for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. The adoption of Topic 326 is not expected to have a material on the Company’s consolidated financial statements and financial statement disclosures.

In August 2020, the FASB issued ASU No. 2020-06 (“ASU 2020-06”) “Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity.” ASU 2020-06 will simplify the accounting for convertible instruments by reducing the number of accounting models for convertible debt instruments and convertible preferred stock. Limiting the accounting models will result in fewer embedded conversion features being separately recognized from the host contract as compared with current GAAP. Convertible instruments that continue to be subject to separation models are (1) those with embedded conversion features that are not clearly and closely related to the host contract, that meet the definition of a derivative, and that do not qualify for a scope exception from derivative accounting and (2) convertible debt instruments issued with substantial premiums for which the premiums are recorded as paid-in capital. ASU 2020-06 also amends the guidance for the derivatives scope exception for contracts in an entity’s own equity to reduce form-over-substance-based accounting conclusions. ASU 2020-06 will be effective January 1, 2024, for the Company. Early adoption is permitted, but no earlier than January 1, 2021, including interim periods within that year. Management is currently evaluating the effect of the adoption of ASU 2020-06 on the consolidated financial statements.
