Summary of Significant Accounting Policies (Policies) | 12 Months Ended
--- | ---
Dec. 31, 2020
Accounting Policies [Abstract] |
Basis of Presentation | Basis of presentation The Company’s consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and the rules and regulations of the Securities and Exchange Commission (“SEC”).
Principles of Consolidation | Principles of consolidation The consolidated financial statements include the accounts of Protagenic Therapeutics, Inc., and its wholly owned Canadian subsidiary, PTI Canada. All significant intercompany balances and transactions have been eliminated in the consolidated financial statements.
Reclassifications | Reclassifications: Reclassifications of prior periods have been made to conform with current year presentation
Use of Estimates | Use of estimates The preparation of consolidated financial statements in conformity with U.S. GAAP 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 date of the consolidated financial statements and the reported amounts of revenue and expense during the reporting period. Actual results could differ from those estimates. Significant estimates underlying the consolidated financial statements include income tax provisions, valuation of stock options and warrants and assessment of deferred tax asset valuation allowance.
Concentrations of Credit Risk | Concentrations of Credit Risk The Company maintains its cash accounts at financial institutions which are insured by the Federal Deposit Insurance Corporation. At times, the Company may have deposits in excess of federally insured limits. The Company has not experienced losses on these accounts and management believes, based upon the quality of the financial institutions, that the credit risk with regard to these deposits is not significant.
Cash and Cash Equivalents | Cash and Cash Equivalents The Company considers all highly liquid investments with an original maturity of three months or less when purchased to be cash equivalents. While the Company’s marketable securities are cash equivalents it is the Company’s policy to present them separately on the balance sheet. As of December 31, 2020 and December 31, 2019, the Company did not have any cash equivalents.
Equipment | Equipment Equipment is stated at cost less accumulated depreciation. Cost includes expenditures for computer equipment. Maintenance and repairs are charged to expense as incurred. When assets are sold, retired, or otherwise disposed of, the cost and accumulated depreciation are removed from the accounts and any resulting gain or loss is reflected in operations. The cost of equipment is depreciated using the straight-line method over the estimated useful lives of the related assets which is three years. Depreciation expense was nominal for the years ended December 31, 2020 and 2019.
Marketable Securities | Marketable Securities The Company accounts for marketable debt securities, the only type of securities it owns, in accordance with sub-topic 320-10 of the FASB Accounting Standards Codification (“Sub-topic 320-10”). Pursuant to Paragraph 320-10-35-1, investments in debt securities that are classified as available for sale shall be measured subsequently at fair value in the consolidated balance sheets at each balance sheet date. Unrealized holding gains and losses for available-for-sale debt securities (including those classified as current assets) shall be excluded from earnings and reported in other comprehensive income until realized. During the years ended December 31, 2020 and 2019, the Company purchased $0 and sold $250,000 in marketable securities, respectively. As of December 31, 2020 and December 31, 2019, the Company owned marketable securities with a total value of $0 and $0, respectively. The Company recorded a realized gain on marketable securities of $0 and $4,435 for the years ended December 31, 2020 and 2019, respectively. As of December 31, 2020 and December 31, 2019, the Company held no marketable securities.
Fair Value Measurements | Fair Value Measurements ASC 820, “Fair Value Measurements and Disclosure,” defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date, not adjusted for transaction costs. ASC 820 also establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad levels giving the highest priority to quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The three levels are described below: Level 1 Inputs – Unadjusted quoted prices in active markets for identical assets or liabilities that is accessible by the Company; Level 2 Inputs – Quoted prices in markets that are not active or financial instruments for which all significant inputs are observable, either directly or indirectly; Level 3 Inputs – Unobservable inputs for the asset or liability including significant assumptions of the Company and other market participants. The carrying amount of the Company’s financial assets and liabilities, such as cash, accounts payable and accrued expenses approximate their fair value because of the short term maturity of those instruments. The carrying value of long-term debt approximates fair value since the related rates of interest approximate current market rates. Transactions involving related parties cannot be presumed to be carried out on an arm’s-length basis, as the requisite conditions of competitive, free-market dealings may not exist. Representations about transactions with related parties, if made, shall not imply that the related party transactions were consummated on terms equivalent to those that prevail in arm’s-length transactions unless such representations can be substantiated. The assets or liability’s fair value measurement within the fair value hierarchy is based upon the lowest level of any input that is significant to the fair value measurement. The following table provides a summary of financial instruments that are measured at fair value on a recurring basis as of December 31, 2020.
|  | Carrying |  |  | Fair Value Measurement Using |

The following table provides a summary of financial instruments that are measured at fair value on a recurring basis as of December 31, 2019.

The table below provides a summary of the changes in fair value, including net transfers in and/or out, of all financial assets and liabilities measured at fair value on a recurring basis using significant unobservable inputs (Level 3) during the year ended December 31, 2020 and the year ended December 31, 2019:
|  | Fair Value Measurement Using Level 3 |
|  | Inputs Total |
Balance, December 31, 2018 |  | $ | 676,079 |
Change in fair value of derivative warrants liabilities |  |  | (343,857 | )
Balance, December 31, 2019 |  | $ | 332,222 |
Change in fair value of derivative warrants liabilities |  |  | (248,552 | )
Balance, December 31, 2020 |  | $ | 83,670 |
The fair value of the derivative feature of the 127,346 and 295,945 warrants issued to the placement agent of the Company’s 2016 private offering (the “2016 Offering”) and to a holder of its debt for debt cancellation in connection with the Merger, respectively on the issuance dates and at the balance sheet dates were calculated using a Black-Scholes option model valued with the following assumptions:
|  | December 31, 2019 |  |  | December 31 2020 |
Exercise price |  |  | 1.25 |  |  |  | 1.25 |
Risk free interest rate |  |  | 1.59 | % |  |  | 0.09 | %
Dividend yield |  |  | 0.00 | % |  |  | 0.00 | %
Expected volatility |  |  | 133 | % |  |  | 169 | %
Contractual term |  |  | 1.15 Years |  |  |  | 0.14 Years |
Risk-free interest rate: The Company uses the risk-free interest rate of a U.S. Treasury Note with a similar expected term on the date of measurement. Dividend yield: The Company uses a 0% expected dividend yield as the Company has not paid dividends to date and does not anticipate declaring dividends in the near future. Volatility: The Company calculates the expected volatility of the stock price based on the corresponding volatility of the Company’s peer group stock price for a period consistent with the warrants’ expected term. Expected term: The Company’s expected term is based on the remaining contractual maturity of the warrants. During the years ended December 31, 2020 and 2019, the Company marked the derivative feature of the warrants to fair value and recorded a gain of $248,552 and a gain of $343,857 relating to the change in fair value, respectively.
Derivative Liability | Derivative Liability The Company evaluates its options, warrants or other contracts, if any, to determine if those contracts or embedded components of those contracts qualify as derivatives to be separately accounted for in accordance with ASC 815-10-05-4 and 815-40-25. The result of this accounting treatment is that the fair value of the embedded derivative is marked-to-market each balance sheet date and recorded as either an asset or a liability. In the event that the fair value is recorded as a liability, the change in fair value is recorded in the consolidated statements of operations as other income or expense. Upon conversion, exercise or cancellation of a derivative instrument, the instrument is marked to fair value at the date of conversion, exercise or cancellation and then the related fair value is reclassified to equity. The classification of derivative instruments, including whether such instruments should be recorded as liabilities or as equity, is re-assessed at the end of each reporting period. Equity instruments that are initially classified as equity that become subject to reclassification are reclassified to liability at the fair value of the instrument on the reclassification date. Derivative instrument liabilities will be classified in the balance sheet as current or non-current based on whether or not net-cash settlement of the derivative instrument is expected within 12 months of the balance sheet date.
Stock-Based Compensation | Stock-Based Compensation The Company accounts for stock based compensation costs under the provisions of ASC 718, “Compensation—Stock Compensation”, which requires the measurement and recognition of compensation expense related to the fair value of stock based compensation awards that are ultimately expected to vest. Stock based compensation expense recognized includes the compensation cost for all stock based payments granted to employees, officers, non-employees, and directors based on the grant date fair value estimated in accordance with the provisions of ASC 718. ASC. 718 is also applied to awards modified, repurchased, or canceled during the periods reported. If any award granted under the Company’s 2016 Equity Compensation Plan (the “2016 Plan”) payable in shares of common stock is forfeited, cancelled, or returned for failure to satisfy vesting requirements, otherwise terminates without payment being made, or if shares of common stock are withheld to cover withholding taxes on options or other awards, the number of shares of common stock as to which such option or award was forfeited, or which were withheld, will be available for future grants under the 2016 Plan. The Company recognizes the impact of forfeitures when they occur.
Basic and Diluted Net (Loss) Per Common Share | Basic and Diluted Net (Loss) per Common Share Basic (loss) per common share is computed by dividing the net (loss) by the weighted average number of shares of common stock outstanding for each period. Diluted (loss) per share is computed by dividing the net (loss) by the weighted average number of shares of common stock outstanding plus the dilutive effect of shares issuable through the common stock equivalents. The effect of dilution on net loss becomes anti-dilutive and therefore is not reflected on the consolidated statements of operations.

Total potentially outstanding dilutive common shares |  |  | 12,075,685 |  |  |  | 9,070,790 |
Research and Development | Research and Development Research and development expenses are charged to operations as incurred.
Foreign Currency Translation | Foreign Currency Translation The Company follows Section 830-10-45 of the FASB Accounting Standards Codification (“Section 830-10-45”) for foreign currency translation to translate the financial statements of the foreign subsidiary from the functional currency, generally the local currency, into U.S. Dollars. Section 830-10-45 sets out the guidance relating to how a reporting entity determines the functional currency of a foreign entity (including of a foreign entity in a highly inflationary economy), re-measures the books of record (if necessary), and characterizes transaction gains and losses. Pursuant to Section 830-10-45, the assets, liabilities, and operations of a foreign entity shall be measured using the functional currency of that entity. An entity’s functional currency is the currency of the primary economic environment in which the entity operates; normally, that is the currency of the environment, or local currency, in which an entity primarily generates and expends cash. The functional currency of each foreign subsidiary is determined based on management’s judgment and involves consideration of all relevant economic facts and circumstances affecting the subsidiary. Generally, the currency in which the subsidiary transacts a majority of its transactions, including billings, financing, payroll and other expenditures, would be considered the functional currency, but any dependency upon the parent and the nature of the subsidiary’s operations must also be considered. If a subsidiary’s functional currency is deemed to be the local currency, then any gain or loss associated with the translation of that subsidiary’s financial statements is included in accumulated other comprehensive income. However, if the functional currency is deemed to be the U.S. Dollar, then any gain or loss associated with the re-measurement of these financial statements from the local currency to the functional currency would be included in the consolidated statements of operations and comprehensive income (loss). If the Company disposes of foreign subsidiaries, then any cumulative translation gains or losses would be recorded into the consolidated statements of operations and comprehensive income (loss). If the Company determines that there has been a change in the functional currency of a subsidiary to the U.S. Dollar, any translation gains or losses arising after the date of change would be included within the consolidated statements of operations and comprehensive income (loss). Based on an assessment of the factors discussed above, the management of the Company determined its subsidiary’s local currency (i.e. the Canadian dollar) to be the functional currency for its foreign subsidiary.
Leases | Leases In February 2016, FASB issued Accounting Standards Update (“ASU”) 2016-02: Leases (Topic 842). The new guidance generally requires an entity to recognize on its balance sheet operating and financing lease liabilities and corresponding right-of-use assets. The standard will be effective for the first interim period within annual reporting periods beginning after December 15, 2018 and early adoption is permitted. The new standard requires a modified retrospective transition for existing leases to each prior reporting period presented or entered into after, the beginning of the earliest comparative period presented in the financial statements. This standard was adopted by the Company on January 1, 2018. The Company elected the package of practical expedients permitted under the transition guidance within the new standard, which among other things, allowed the Company to carry forward the historical lease classification. The adoption of this standard did not have a material impact on the Company’s consolidated financial statements and related disclosures.
Recent Accounting Pronouncements | Recent Accounting Pronouncements Management does not believe that any recently issued, but not effective, accounting standards, if currently adopted, would have a material effect on the Company’s financial statements.
