Summary of Significant Accounting Policies	2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES *Consolidation.* The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries, Non-Invasive Monitoring Systems of Florida, Inc., which has no current operations, and NIMS of Canada, Inc., a Canadian corporation, which has no current operations. All inter-company accounts and transactions have been eliminated in consolidation. *Discontinued Operations.* For the three months ended October 31, 2019 and 2018, results from operations for our Exer-Rest Business are classified as discontinued operations. The carve out of the discontinued operations (i) were prepared in accordance with the SEC’s carve out rules under Staff Accounting Bulletin (“SAB”) Topic 1B1 and (ii) are derived from identifying and carving out the specific assets, liabilities, operating expenses and interest expense associated with the Exer-Rest Business’s operations. Discontinued operations expense allocations, consisting of warehouse rent and other inventory related expenses incurred by us, are directly attributed to discontinued operations (see Note 3). *Use of Estimates.* The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions, such as deferred taxes as estimates, that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and reported amounts of expenses during the reporting period. Actual results could differ materially from these estimates. *Cash and Cash Equivalents.* The Company considers all highly liquid short-term investments purchased with an original maturity date of three months or less to be cash equivalents. The Company had approximately $333,000 and $353,000, on deposit in bank operating accounts at October 31, 2019 and July 31, 2019, respectively. *Income Taxes.* The Company provides for income taxes using an asset and liability based approach. Deferred income tax assets and liabilities are recorded to reflect the tax consequences in future years of temporary differences between the carrying amounts of assets and liabilities for financial statement and income tax purposes. The deferred tax asset for loss carryforwards and other potential future tax benefits has been fully offset by a valuation allowance since it is uncertain whether any future benefit will be realized. The utilization of the loss carryforward is limited to future taxable earnings of the Company and may be subject to severe limitations if the Company undergoes an ownership change pursuant to the Internal Revenue Code Section 382. The Company files its tax returns as prescribed by the laws of the jurisdictions in which it operates. Tax years ranging from 2015 to 2019 remain open to examination by various taxing jurisdictions as the statute of limitations has not expired. It is the Company’s policy to include income tax interest and penalty expense in its tax provision. *Stock-based compensation.* The Company recognizes all share-based payments, including grants of stock options, as operating costs and expenses, based on their grant date fair values. Stock-based compensation expense is recognized over the vesting life of the underlying stock options and is included in selling, general and administrative costs and expenses in the condensed consolidated comprehensive statements of operations for all periods presented. *Fair Value of Financial Instruments.* Fair value estimates discussed herein are based upon certain market assumptions and pertinent information available to management as of October 31, 2019 and July 31, 2018. The respective carrying value of certain on-balance-sheet financial instruments such as cash, prepaid expenses, deposits, other current assets, accounts payable and accrued expenses approximate fair values because they are short term in nature or they bear current market interest rates. *Loss Contingencies.* We recognize contingent losses that are both probable and estimable. In this context, we define probability as circumstances under which events are likely to occur. In regard to legal costs, we record such costs as incurred. *Recent Accounting Pronouncements.* The Company considers the applicability and impact of all Accounting Standard Updates (“ASU’s”). ASU’s not discussed below were assessed and determined to be either not applicable or are expected to have minimal impact on our consolidated balance sheets or consolidated comprehensive statement of operations. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230). This standard addresses the classification of eight specific cash flow issues with the objective of reducing the existing diversity in practice. ASU 2016-15 will be effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years, with early adoption permitted. The Company implemented this ASU on August 1, 2018. The adoption of this update did not have an impact on the Company’s consolidated financial statements. In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-02, Leases (Topic 842). ASU 2016-02 impacts any entity that enters into a lease with some specified scope exceptions. This new standard establishes a right-of-use (ROU) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the statement of operations. The guidance updates and supersedes Topic 840, Leases. For public entities, ASU 2016-02 is effective for fiscal years, and interim periods with those years, beginning after December 15, 2018, and early adoption is permitted. A modified retrospective transition approach is required for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. The Company currently has no long-term leases. However, in the event that the Company should enter any long-term leases it would then evaluate the effect that the new guidance would have on its consolidated financial statements and related disclosures.
