Summary of Significant Accounting Policies (Policies) | 12 Months Ended
--- | ---
Nov. 30, 2018
Use of Estimates [Policy Text Block] |
a) | Use of Estimates
| The preparation of the accompanying consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions about future events. These estimates and the underlying assumptions affect the amounts of assets and liabilities reported and reported amount of revenues and expenses. Significant estimates include accruals, valuation allowance for deferred tax assets, estimates for calculations of stock-based compensation, estimating the useful life of its property and equipment, estimating the useful life of its patent rights and accounting for conversion features on convertible debt transactions. These estimates are based on management’s best estimates and judgment. Management will adjust such estimates and assumptions when facts and circumstances dictate. As future events and their effects cannot be determined with certainty, actual results could differ significantly from these estimates. |
Income Taxes [Policy Text Block] |
b) | Income Taxes
| The Company accounts for income taxes under FASB Codification Topic 740-10-25 ("ASC 740-10- 25"). Under ASC 740-10-25, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Under ASC 740- 10-25, the effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. The Company provides a valuation allowance for deferred tax assets for which it does not consider realization of such assets is not more than likely. The Company did not incur any material impact to its financial condition or results of operations due to the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. |
Revenue Recognition [Policy Text Block] |
c) | Revenue Recognition
| The Company records revenue when it is realized, or realizable and earned. The Company considers revenue to be realized, or realizable and earned, when the following revenue recognition requirements are met: persuasive evidence of an arrangement exists; the products have been shipped to the customer; the sales price is fixed or determinable; and collectability is reasonably assured. |
Loss Per Share [Policy Text Block] |
d) | Loss Per Share
| Basic loss per share is computed by dividing net loss by the weighted average number of common shares outstanding for the year. Diluted loss per share is computed by dividing net loss by the weighted average number of common shares outstanding plus common stock equivalents (if dilutive) related to stock options and warrants for each year and the conversion feature of convertible debentures. There were no common equivalent shares outstanding at November 30, 2018 and 2017 that have been included in dilutive loss per share calculation as the effects would have been anti-dilutive. At November 30, 2018, there are 6,376,667 options and 26,041,160 warrants outstanding, which are convertible into equal number of common shares of the Company. At November 30, 2017, there were 4,866,667 options and 20,941,160 warrants outstanding, which were convertible into equal number of common shares of the Company.
Stock-Based Compensation [Policy Text Block] |
e) | Stock-Based Compensation
| All stock option awards granted to employees are valued at fair value by using the Black-Scholes or Binomial Lattice option pricing model and recognized on a straight-line basis over the service periods of each award. The Company accounts for equity instruments issued in exchange for the receipt of goods or services from non- employees using the estimated fair market value of the consideration received or the estimated fair value of the equity instruments issued, whichever is more reliably measurable. The value of equity instruments issued for consideration for employees and non-employee services is determined on the earlier of a performance commitment or completion of performance by the provider of goods or services. If there is a modification of the terms of an award, either by repricing or extending the expiry of the award, the award is re-measured. If the modification results in an increase in the fair value of the new award as compared to the old award immediately prior to the modification, the excess fair value is recognized as compensation expense.
Foreign Currency [Policy Text Block] |
f) | Foreign Currency
| The parent company maintains its books and records in U.S. dollars which is its functional and reporting currency. The Company’s operating subsidiary is a foreign private company and maintains its books and records in Canadian dollars (the functional currency). The subsidiary’s financial statements are converted to US dollars for consolidation purposes. The translation method used is the current rate method. Under the current rate method, all assets and liabilities are translated at the current rate, stockholders’ equity accounts are translated at historical rates, and revenues and expenses are translated at average rate for the year. The resulting translation adjustment has been included in accumulated other comprehensive loss. Gains or losses resulting from transactions in currencies other than the functional currency are reflected in the consolidated statement of operations and comprehensive loss for the reporting periods.
Comprehensive loss [Policy Text Block] |
g) | Comprehensive Loss
| Comprehensive loss includes all changes in equity (net assets) during a period from non-owner sources. Items included in comprehensive loss, which are excluded from net loss, include foreign currency translation adjustments relating to its Canadian subsidiary. |
Financial Instruments [Policy Text Block] |
h) | Financial Instruments
| The carrying amount of accounts receivable and accounts payable and accrued liabilities, approximated their fair value because of the relatively short maturity of these instruments. The Company determines fair value based on its accounting policy fair value measurement (i.e. exit price that would be recovered for an asset or paid to transfer a liability in an orderly transaction between market participants on the measurement date). The Company has not used derivative financial instruments such as forwards to hedge foreign currency exposures. Convertible debt issued is initially recognized at fair value. Derivative liabilities are measured at fair value on each reporting period and debt is subsequently measured at amortized cost. |
Fair Value Measurement [Policy Text Block] |
i) | Fair Value Measurement
| The Company follows ASC 820-10, "Fair Value Measurements and Disclosures" (ASC 820-10), which among other things, defines fair value, establishes a consistent framework for measuring fair value and expands disclosure for each major asset and liability category measured at fair value on either a recurring or nonrecurring basis. Fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market- based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, a three-tier fair value hierarchy has been established, which prioritizes the inputs used in measuring fair value as follows: • Level 1 —Inputs are unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date. • Level 2 —Inputs (other than quoted prices included in Level 1) are either directly or indirectly observable for the asset or liability through correlation with market data at the measurement date and for the duration of the instrument’s anticipated life. • Level 3 —Inputs reflect management’s best estimate of what market participants would use in pricing the asset or liability at the measurement date. Consideration is given to the risk inherent in the valuation technique and the risk inherent in the inputs to the model. The carrying values of cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities approximate their fair values because of the short-term nature of these instruments. Embedded derivatives included in the convertible debentures are measured at fair value on a recurring basis using Level 3 inputs, and the fair value is determined using unobservable inputs. The change in fair value of the embedded derivative related to the convertible debentures of $(188,543) for the year ended November 30, 2018 (November 30, 2017 - $239,802) is reflected as change in fair value of derivative liabilities in the accompanying consolidated statements of operations and comprehensive loss (see Note 14). |
Convertible debt instruments [Policy Text Block] |
j) |  | Convertible Debt Instruments
|  | When the Company has determined that the embedded conversion options should not be bifurcated from their host instruments the Company accounts for convertible debt instruments in accordance with ASC 470-20 Debt with Conversion and Other Options. The Company records, when necessary, discounts to convertible notes for the intrinsic value of conversion options embedded in debt instruments based upon the differences between the fair value of the underlying common stock at the commitment date of the note transaction and the effective conversion price embedded in the note. The Company amortizes any debt discount over the term of the notes, using the straight-line method, which approximates the effective interest method. The Company records, when necessary, any induced conversion expense, at the time of conversion for the difference between the reduced conversion price per share and the original conversion price per share.
Intellectual Property [Policy Text Block] |
k) | Intellectual Property
| The Company’s policy has been to write off costs incurred in connection with non-provisional and provisional patent costs as they are incurred, as a recoverability of such expenditure is uncertain. The perpetual, irrevocable, exclusive and non-exclusive license to use technology with respect to the cost of patent rights acquired in 2018 is capitalized to patent rights and are amortized over their estimated useful life, currently estimated to be 15 years.
Property and Equipment [Policy Text Block] |
l) | Property and Equipment
|  | Property and equipment are recorded at cost less accumulated depreciation. Depreciation is provided commencing in the month following acquisition using the following annual rate and method:
| Computer equipment and software | 30% declining balance method
| Furniture and fixtures | 30% declining balance method
| Leasehold improvements | Straight line over period of lease
| Moulds | 20% straight line over 5 years
Cash and cash equivalents [Policy Text Block] |
m) |  | Cash and Cash Equivalents
|  | Cash consists of cash and cash equivalents, which are short-term, highly liquid investments with original terms to maturity of 90 days or less.
Impairment of Long-lived Assets [Policy Text Block] |
n) | Impairment of Long-lived Assets
| Long-lived assets to be held and used are analyzed for impairment whenever events or changes in circumstances indicate that the related carrying amounts may not be recoverable. The Company evaluates at each balance sheet date whether events and circumstances have occurred that indicate possible impairment. If there are indications of impairment, the Company uses future undiscounted cash flows of the related asset or asset group over the remaining life in measuring whether the assets are recoverable. In the event such cash flows are not expected to be sufficient to recover the recorded asset values, the assets are written down to their estimated fair value.
Inventories [Policy Text Block] |
o) | Inventories
| Inventories comprise primarily of Blunt Impact Projectiles (finished goods) and are valued at the lower of cost and net realizable value with cost being determined on the first-in, first-out basis. Costs consist of sub- contracted manufacturing costs. |
Consolidation [Policy Text Block] |
p) | Consolidation
| These consolidated financial statements include the accounts of Security Devices International, Inc. and entities it controls. Control exists when SDI has the power, directly or indirectly, to govern the financial and operating policies of an entity or arrangement to obtain benefit from its activities. In assessing control, potential voting rights that currently are exercisable are considered. The financial statements of the subsidiary are included in the consolidated financial statements from the date that control commences until the date that control ceases. These consolidated financial statements include the results of SDI and its wholly-owned subsidiary, Security Devices International Canada Corp. |
Recent Accounting Pronouncements [Policy Text Block] |
q) | Recent Accounting Pronouncements
In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”). Subsequently, the FASB issued several updates to ASU 2014-09, which are codified in Accounting Standards Codification (“ASC”) Topic 606 (“ASC 606”). ASC 606 also includes new guidance on costs related to a contract, which is codified in ASC Subtopic 340-40 (“ASC 340-40”). In applying ASC 606, revenue is recognized when control of promised goods or services transfers to a customer and is recognized in an amount that reflects the consideration which the entity expects to receive in exchange for those goods or services. The major provisions of the new standard include: the determination of enforceable rights and obligations between parties; the identification of performance obligations including those related to material right obligations; the allocation of consideration based upon relative standalone selling price; accounting for variable consideration; the determination of whether performance obligations are satisfied over time or at a point in time; and enhanced disclosure requirements. ASC 606 will be effective for the Company beginning December 1, 2018 and permits two methods of adoption: retrospectively to each prior reporting period presented (“full retrospective method”) or retrospectively with the cumulative effect of the initial application recognized at the date of initial application (“modified retrospective method”). The Company is in the process of evaluating the amendments to determine if they have a material impact on the Company’s financial position, results of operations or cash flow. In May 2017, the FASB issued ASU No. 2017-09, "Compensation - Stock Compensation: Scope of Modification Accounting," which provides guidance about which changes to the terms or conditions of a share- based payment award require an entity to apply modification accounting. An entity will account for the effects of a modification unless the fair value of the modified award is the same as the original award, the vesting conditions of the modified award are the same as the original award and the classification of the modified award as an equity instrument or liability instrument is the same as the original award. The update is effective for fiscal year 2019. The update is to be adopted prospectively to an award modified on or after the adoption date. Early adoption is permitted. The Company is in the process of evaluating the amendments to determine if they have a material impact on the Company’s financial position, results of operations or cash flow. In January 2016, the FASB issued ASU 2016-01, Financial Instruments - Overall (subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities (ASU 2016-01). This amendment requires equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income. The amendment simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment. It eliminates the requirement for public business entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet. The amendment requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes. Additionally, the update requires an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments and requires an entity to separate presentation of financial assets and financial liabilities by measurement category and form of financial asset (that is, securities or loans and receivables) on the balance sheet or the accompanying notes to the financial statements. The standard is effective for the Company on December 15, 2017, with early adoption permitted. The Company is evaluating the effect that ASU 2016-01 will have on its financial statements and related disclosures. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) (ASU 2016-02). The FASB issued the update to require the recognition of lease assets and liabilities on the balance sheet of lessees. ASU 2016-02 will be effective for the Company on December 1, 2019, including interim periods. ASU 2016-02 requires a modified retrospective transition method with the option to elect a package of practical expedients. Early adoption is permitted. The Company is evaluating the effect that ASU 2016-02 will have on its financial statements and related disclosures. In January 2017, the FASB issued ASU 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment (ASU 2017-04). The FASB issued the update to simplify the measurement of goodwill by eliminating step 2 from the goodwill impairment test. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. ASU 2017-04 will be effective for public companies for fiscal years beginning after December 15, 2019, including interim periods. Early adoption is permitted. The Company is evaluating the effect that ASU 2017-04 will have on its financial statements and related disclosures. In July 2017, the FASB issued ASU 2017-11, Earnings Per Share (Topic: 260), Distinguishing Liabilities from Equity (Topic: 480), Derivatives and Hedges (Topic 815) (ASU 2017-11). FASB issued the update to simplify the accounting for certain financial instruments with down round features. ASU 2017-11 will be effective for public companies for fiscal years beginning after December 15, 2018, including interim periods. Earlier adoption is permitted for all entities as of the beginning of an interim period for which financial statements (interim or annual) have not been issued or have not been made available for issuance. In June 2018, the FASB issued ASU 2018-07, Compensation – Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting (ASU 2018-07). FASB issued the update to include share-based payment transaction for acquiring goods or services from nonemployees in Topic 718, Compensation – Stock Compensation. ASU 2018-07 will be effective for public companies for fiscal years beginning after December 15, 2018, including interim periods. Early adoption is permitted, but no earlier than a company’s adoption date of Topic 606, Revenue from Contracts with Customers. In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic: 820): Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement (ASU 2018-13). FASB issued the update to modify the disclosure requirements in Topic 820. ASU 2018-07 will be effective for public companies for fiscal years beginning after December 15, 2018, including interim periods. Early adoption is permitted.
