The fair value of each stock option or warrant is estimated on the date of grant using a binomial option-pricing model or the Monte Carlo valuation model. The expected life of stock options or warrants represents the period of time that the stock options or warrants are expected to be outstanding, based on the simplified method. Expected volatilities are based on historical volatility of the Company's common stock, among other factors. The Company uses the simplified method within the binomial option-pricing valuation model due to the Company's short trading history. The risk-free rate related to the expected term of the stock options or warrants is based on the US Treasury yield curve in effect at the time of grant. The dividend yield is zero.

During fiscal 2016, the Company granted warrants to purchase 24,032 common shares with an exercise price of $32.50 per share in connection with the acquisition of a note payable and line of credit; warrants for the purchase of 14,786 shares vested immediately, 3,696 vested upon the disbursement of the second tranche of the related note payable, and 5,550 vest evenly in the event of three available increases on the related line of credit (see Note 9). The warrants expire in February 2023, may be exercised via cashless exercise and are puttable upon expiration or liquidation for the greater of $500,000 or up to 6.5% of the equity value of the Company, depending on the number of warrants vested. The fair value of the warrants upon grant of $3,731,969 was recorded as a derivative and the Company received cash of $2,967 upon issuance of the warrants. The Company recognized $1,419,541 as debt discount for the portion allocated to the note payable and the debt discount is being amortized over the life of the note payable to interest expense. During September 2016, the Company entered into a conditionally effective warrant cancellation agreement with the warrant holders, which has expired (see Note 17).

During February 2016, the Company exchanged warrants held by the holders of its Series F Preferred for the purchase of 11,070 shares of common stock in connection with the redemption of Series F Preferred for new warrants for the purchase of the same number of shares on different terms. The new warrants were initially exercisable for $150 per share, adjustable to any lower rates granted through equity sales or other conversion rates provided by issuances of other debt, warrants, options or other instruments, with the exception of certain other raises. During September 2016, the Company issued warrants for the purchase of common stock that adjusted the warrants to have an exercise price per share equal to the lesser of (i) 80% of the per share price of the common stock of the Offering, (ii) $25 per share, (iii) 80% of the unit price in the Offering (if applicable), or (iv) the exercise price of any warrants issued in the Offering. On December 11, 2017, the Company entered into Securities Purchase Agreements that adjusted the conversion rate to exercise price per share equal to the lesser of (i) 80% of the per share price of common stock in a contemplated private placement of securities of up to $5,000,000, contemplated to take place within six months of the effective date (the “Private Placement”) (ii) $3.00 per share, (iii) 80% of the offering price in the Private Placement (if applicable), or (iv) 80% of the exercise price of any warrants issued in the Private Placement, in each case subject to adjustment (see Note 18). The new warrants expire in February 2021, and may be exercised via cashless exercise. Additional warrants for the purchase of 16,000 shares of common stock may be issued in the event of default on the related notes payable, exercisable at $0.50 per share, with 25% issuable upon the first event of default, 37.5% upon the second event, and 37.5% upon the third event. The warrants issuable upon default expire in February 2026 (if issued), may be exercised via cashless exercise, and are puttable upon expiration or liquidation with the primary warrants. The new warrants may only be exercised to the extent the respective holder would own a maximum of 4.99% of the Company’s common stock after exercise, but the holders may elect to increase the maximum to 9.99%. The Company recognized a deemed dividend of $6,484,236 as a result of the exchange and related redemption of Series F Preferred.

During September 2016, the Company granted warrants to purchase 20,000 shares in connection with the acquisition of a note payable at an exercise price per share equal to the lesser of (i) 80% of the per share price of the common stock of the Offering, (ii) $25 per share, (iii) 80% of the unit price in the Offering (if applicable), or (iv) the exercise price of any warrants issued in the Offering. Upon the closing of the Offering, the number of shares issuable under the warrant will reset to an amount of shares equal to the aggregate exercise amount of the warrants (as defined therein) divided by the exercise price then in effect. The warrants expire in September 2021, and may be exercised via cashless exercise. The warrants may only be exercised to the extent the holder would own a maximum of 9.99% of the Company’s common stock after exercise. The Company recognized $220,000 of the $493,590 fair value of the warrants as a debt discount, which is being amortized over the life of the borrowing, and recognized the remaining $273,590 as a loss on derivatives liability. In the event the Company borrows additional amounts above the initial $500,000 under the note payable, the Company will be required to issue additional warrants with an aggregate exercise amount equal to 100% of the additional amount borrowed with similar terms to warrants issued as part of the initial borrowing. During the nine months ended June 30, 2017, the Company borrowed an additional $1,000,000 on the note and issued warrants for the purchase of 40,000 shares of common stock with the same terms as the initial warrants. The Company recognized the $2,103,341 fair value of the warrants as debt discounts, which are being amortized over the remaining life of the borrowing. Effective March 3, 2017, the note was amended to increase the maximum principal sum from $1,500,000 to $2,000,000 under which the Company borrowed an additional $200,000 in consideration and issued the lender a warrant to purchase up to 8,000 shares of common stock with the same terms as the warrants previously issued under the previous terms of the note. The Company recognized the $407,947 fair value of the warrants as part of the total on extinguishment of debt of $501,969.

During the nine months ended June 30, 2017, the Company measured the fair value of warrants classified as liabilities on the date of issuance and on each re-measurement date using the Monte Carlo valuation model. For this liability, the Company and specialist developed their own assumptions that do not have observable inputs or available market data to support the fair value. This method of valuation involves using inputs such as the fair value of the Company’s common stock, stock price volatility, the contractual term of the warrants, risk–free interest rates and dividend yields. Due to the nature of these inputs, the valuation of the warrants uses Level 3 measurements. The following assumptions were used:


Exercise price				$2.50 - $25.00
Expected term (years)				0.21 - 4.93
Volatility				128% - 194%
Risk-free rate				0.49% - 1.99%
Dividend rate				0%
Common stock price				$2.50 - $25.00

The following table summarizes information about stock options and warrants outstanding as of June 30, 2017:

As of June 30, 2017, the outstanding warrants have an aggregate intrinsic value of $0 and the weighted average remaining term of the warrants was 4.52 years. The total compensation cost related to unvested awards not yet recognized (warrants and shares) was $38,468.
