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.

Inventory

Inventory

Inventory is stated at the lower of cost or net realizable value. Cost is determined using the weighted average method. The Company periodically evaluates its inventory for any obsolete or slow moving items based on production lot number and advances in production design or technology. Any inventory determined to be obsolete or slow moving inventory is written down to its net realizable value.

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 Antigen in August 2003 and the acquisition of HDS 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.

Intangible Assets

Intangible Assets

The costs of in-process research and development (“IPR&D”), related to the Company’s business combination with HDS, 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, 2018, the IPR&D and licenses are not impaired.

Derivative Warrant Liability

Derivative Warrant Liability

The Company’s derivative warrant instruments are measured at fair value using the binomial valuation model which takes into account, as of the valuation date, factors including the current exercise price, the expected life of the warrant, the current price of the underlying stock and its expected volatility, expected dividends on the stock and the risk-free interest rate for the term of the warrant. The liability is revalued at each reporting period and changes in fair value are recognized in the consolidated statements of operations and comprehensive loss under the caption “Change in fair value of derivative liabilities.”

Income Taxes

Income Taxes

Income taxes are accounted for under the asset and liability method prescribed by FASB ASC Topic 740. These standards require a company to determine whether it is more likely than not that a tax position will be sustained upon examination based upon the technical merits of the position. If the more likely than not threshold is met, a company must measure the tax position to determine the amount to recognize in the financial statements. Deferred income taxes are recorded for temporary differences between financial statement carrying amounts and the tax basis of assets and liabilities. Deferred tax assets and liabilities reflect the tax rates expected to be in effect for the years in which the differences are expected to reverse. A valuation allowance is provided if it is more likely than not that some or all of the deferred tax asset will not be realized. At July 31, 2018 and 2017, the Company had a full valuation allowance equal to the amount of the net deferred tax asset.

The Company adopted the FASB guidance concerning accounting for uncertainty in income taxes, which clarifies the accounting and disclosure for uncertainty in tax positions, as of August 1, 2007. The guidance requires that the Company determine whether it is more likely than not that a tax position will not be sustained upon examination by the appropriate taxing authority. If a tax position does not meet the more likely than not recognition criterion, the guidance requires that the tax position be measured at the largest amount of benefit greater than 50 percent not likely of being sustained upon ultimate settlement. Based on the Company’s evaluation, management has concluded that there are no significant uncertain tax positions requiring recognition in the consolidated financial statements.

Net Income (Loss) per Common Share

Net Income (Loss) per Common Share

Net earnings per share is computed by dividing income (loss) available to common stockholders by the weighted average number of common shares outstanding during the year. Diluted earnings per share gives effect to all dilutive potential common shares outstanding during the year. The computation of diluted earnings per share does not assume conversion, exercise or contingent exercise of securities that would have an anti-dilutive effect on earnings. Diluted earnings per share is calculated using the treasury stock method.

Foreign Currency Translation

Foreign Currency Translation

The functional and reporting currency of the Company and most of its subsidiaries is the United States Dollar. One subsidiary, Generex Pharmaceuticals, Inc., has a functional currency of the Canadian Dollar. Foreign denominated assets and liabilities of the Company are translated into U.S. dollars at the prevailing exchange rates in effect at the end of the reporting period. Revenue and expense accounts are translated at an average of exchange rates which were in effect during the period. Translation adjustments that arise from translating the foreign subsidiary’s financial statements from its functional currency to the Company’s reporting currency are recorded in the other comprehensive loss component of stockholders’ equity. Gains and losses resulting from foreign currency transactions are included in the consolidated statement of operations and comprehensive loss.

Use of Estimates

Use of Estimates

The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods.

The Company evaluates its estimates, including those related to long lived assets (including patents) impairment valuations, derivatives and contingencies and litigation, on an ongoing basis. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

Critical accounting estimates are reviewed and discussed with the Board of Directors. The Company considers an accounting estimate to be critical if it requires assumptions to be made that were uncertain at the time the estimate was made, if changes in the estimate or if different estimates that could have been selected would have a material impact on our results of operations or financial condition.
