Note 3 - Summary of Significant Accounting Policies

Basis of Presentation

All amounts are presented in U.S. Dollars.

Use of Estimates

The preparation of 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 liabilities at dates of the financial statements and the reported amounts of revenue and expenses during the periods. Actual results could differ from these estimates. The Company’s significant estimates and assumptions include the fair value of financial instruments, stock-based compensation and the valuation allowance relating to the Company’s deferred tax assets.

Concentrations of Credit Risk

The Company maintains deposits in a financial institution which is insured by the Federal Deposit Insurance Corporation (“FDIC”). At various times, the Company has deposits in this financial institution in excess of the amount insured by the FDIC. The Company has not experienced any losses in such accounts and believes it is not exposed to any significant credit risk.

Investments

Investments as of June 30, 2020 and December 31, 2019 consist of Certificates of Deposit totaling $249,077 and $0, respectively. Additional investments as of June 30, 2020 and December 31, 2019 consist of U.S. Treasury Bills, which are classified as held-to-maturity, totaling $5,414,619 and $9,505,777, respectively. The Company determines the appropriate balance sheet classification of its investments at the time of purchase and evaluates the classification at each balance sheet date. Because the maturity dates of the additional investments as of June 30, 2020 and December 31, 2019 were all less than three months at the time of purchase, the amounts were reclassified to cash equivalents. All of the Company’s U.S. Treasury Bills matured within the subsequent twelve months from the date of purchase. Unrealized gains and losses were de minimus.

Common Stock Purchase Warrants

The Company classifies as equity any contracts that (i) require physical settlement or net-share settlement or (ii) provide the Company with a choice of net-cash settlement or settlement in its own shares (physical settlement or net-share settlement) providing that such contracts are indexed to the Company’s own stock. The Company classifies as assets or liabilities any contracts that (i) require net-cash settlement (including a requirement to net cash settle the contract if an event occurs and if that event is outside the Company’s control), or (ii) give the counterparty a choice of net-cash settlement or settlement in shares (physical settlement or net-share settlement). The Company assesses classification of its common stock purchase warrants and other free-standing derivatives at each reporting date to determine whether a change in classification between assets, liabilities and equity is required.  The Company’s free-standing derivatives consist of warrants to purchase common stock that were issued in connection with its notes payable and a private offering. The Company evaluated these warrants to assess their proper classification using the applicable criteria enumerated under U.S. GAAP and determined that the common stock purchase warrants meet the criteria for equity classification in the accompanying balance sheets as of June 30, 2020 and December 31, 2019.

Share-Based Payment

The Company accounts for share-based payments using the fair value method. For employees and directors, the fair value of the award is measured, as discussed below, on the grant date. For non-employees, fair value is generally valued based on the fair value of the services provided or the fair value of the equity instruments on the measurement date, whichever is more readily determinable. The Company has granted stock options at exercise prices equal to the closing price of the Company’s common stock as reported by Nasdaq, with input from management on the date of grant. Upon exercise of an option or warrant, the Company issues new shares of common stock out of its authorized shares.

The weighted-average fair value of options and warrants has been estimated on the grant date or measurement date using the Black-Scholes pricing model. The fair value of each instrument is estimated on the grant date or measurement date utilizing certain assumptions for a risk-free interest rate, volatility and expected remaining lives of the awards. The risk-free interest rate used is the United States Treasury rate for the day of the grant having a term equal to the life of the equity instrument. Beginning with the first quarter of the year ended December 31, 2019, the fair value of stock-based payment awards issued was estimated using a volatility derived from the Company’s share price. Prior to the first quarter of the year ended December 31, 2019, the Company had a limited history of being publicly traded and estimated the fair value of stock-based payment awards using a volatility derived from an index of comparable entities. The assumptions used in calculating the fair value of share-based payment awards represent management’s best estimates, but these estimates involve inherent uncertainties and the application of management judgment. As a result, if factors change and the Company uses different assumptions, the Company’s stock-based compensation expense could be materially different in the future.

The weighted-average Black-Scholes assumptions are as follows:

As of June 30, 2020, total unrecognized stock option compensation expense was $4,139,054, which will be recognized as those options vest over a period of approximately four years. The amount of future stock option compensation expense could be affected by any future option grants or by any option holders leaving the Company before their grants are fully vested.

Net Loss Per Share of Common Stock

Basic net loss per share is computed by dividing net loss attributable to common stockholders by the weighted average number of common shares outstanding during the period.  Diluted net earnings per share reflects the potential dilution that could occur if securities or other instruments to issue common stock were exercised or converted into common stock.  Potentially dilutive securities are excluded from the computation of diluted net loss per share as their inclusion would be anti-dilutive and consist of the following:

Recent Accounting Pronouncement

In December 2019, the Financial Accounting Standards Board issued ASU No. 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes” (“ASU 2019-12”), which is intended to simplify the accounting for income taxes. ASU 2019-12 removes certain exceptions to the general principles in Topic 740. This guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020, with early adoption permitted. The Company is currently evaluating the impact of this standard on its consolidated financial statements and related disclosures.
