Note 3 - Summary of Significant Accounting Policies

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 the Company’s stock, stock-based compensation, debt discount 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.

Investments

Investments consist of U.S Treasury Bills and Certificates of Deposit. 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. 

The Company had $5,745,024 of short-term investments at September 30, 2015.

Deferred Offering Costs

The Company classifies amounts related to the IPO not closed as of the balance sheet date as Deferred Offering Costs. During the nine months ended September 30, 2015, the Company reclassified Deferred Offering Costs in the amount of $749,386 to Additional Paid-in-Capital.

During the nine months ended September 30, 2015, the Company incurred $35,811 of additional offering related costs. These costs were recorded as a reduction in Additional Paid-in-Capital in the accompanying condensed balance sheets.

Fair Value of Financial Instruments

The Company measures the fair value of financial assets and liabilities based on the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The Company utilizes three levels of inputs that may be used to measure fair value:

Level 1 - quoted prices in active markets for identical assets or liabilities

Level 2 - quoted prices for similar assets and liabilities in active markets or inputs that are observable

Level 3 - inputs that are unobservable (for example, cash flow modeling inputs based on assumptions)

The carrying amounts of cash, investments, accounts payable, accrued liabilities and debt approximate fair value due to the short-term nature of these instruments.

Common Stock Purchase Warrants

The Company classifies as equity any contracts that (i) require physical settlement or net-share settlement or (ii) provides 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) gives 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 and liabilities is required.  The Company’s free standing derivatives consist of warrants to purchase common stock that were issued in connection with its notes payable, warrants to purchase common stock that were issued in connection with the Company’s IPO and concurrent private placement and compensation options issued to the agents in the IPO exercisable for shares of common stock and common stock purchase warrants. The Company evaluated these securities to assess their proper classification using the applicable criteria enumerated under U.S. GAAP and determined that they meet the criteria for equity classification in the condensed balance sheet as of September 30, 2015 and December 31, 2014.

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 and re-measured on each financial reporting dates until the service is complete. The Company has granted stock options at exercise prices no less than the fair market value as determined by the board of directors, with input from management.

The weighted-average fair value of options and warrants has been estimated on the date of grant using the Black-Scholes pricing model. The fair value of each instrument is estimated on the date of grant utilizing certain assumptions for a risk free interest rate, volatility and expected remaining lives of the awards. Since the Company has a limited history of being publicly traded, the fair value of stock-based payment awards issued was estimated 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. In addition, the Company is required to estimate the expected forfeiture rate and only recognize expense for those shares expected to vest. In estimating the Company’s forfeiture rate, the Company analyzed its historical forfeiture rate, the remaining lives of unvested options, and the number of vested options as a percentage of total options outstanding. If the Company’s actual forfeiture rate is materially different from its estimate, or if the Company reevaluates the forfeiture rate in the future, the stock-based compensation expense could be significantly different from what the Company has recorded in the current period.

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

As of September 30, 2015, total unrecognized stock option compensation expense is $919,044, 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:

* September 30, 2014, excludes the impact of Put agreements, which subscribed certain shareholders of the Company to purchase additional shares and warrants contingent upon, and concurrently with, completion of the IPO.

Recent Accounting Pronouncements

Recent accounting standards that have been issued or proposed by the FASB or other standards-setting bodies that do not require adoption until a future date are not expected to have a material impact on the Company’s financial statements upon adoption.
