Note 4 – Convertible Instruments

Series B Convertible Preferred Stock

During fiscal 2010, the Company issued 400,000 shares of Series B Convertible Preferred Stock par value $0.001 (“Series B”) at $5.00 per share for cash proceeds totaling $2,009,000, of which 92,100 shares remain outstanding at February 28, 2018. Each share of the Series B is convertible into ten shares of the Company’s $0.001 par common stock including any accrued dividends, with an effective fixed conversion price of $0.50 per share. The holders of the Series B can only convert their shares to common shares provided the Company has sufficient authorized common shares at the time of conversion. Accordingly, the conversion option was contingent upon the Company increasing its authorized common shares, which occurred in April 2010, when the Company’s stockholders approved an increase in the authorized shares of common stock to 100,000,000. At the commitment date, which occurred upon such stockholder approval, the conversion option related to the Series B was beneficial. The intrinsic value of the conversion option at the commitment date resulted in a constructive dividend to the Series B holders of approximately $6 million. The constructive dividend increased and decreased additional paid-in capital by identical amounts. The Series B has liquidation preferences over the common shares at $5.00 per share plus any accrued dividends. Dividends are payable to the Series B holders when declared by the board of directors at the rate of $0.25 per share per annum. Such dividends are cumulative and accrue whether or not declared and whether or not there are any profits, surplus or other funds or assets of the Company legally available. The Series B holders have no voting rights.

Short-Term Convertible Notes

During the year ended May 31, 2017, the Company issued $1.15 million of unsecured convertible promissory notes (the “Notes”), with a maturity date of January 31, 2018, and related warrants to investors for cash. The principal amount of the Notes, including any accrued but unpaid interest thereon, is convertible at the election of the holder at any time into shares of common shares at any time prior to maturity at a conversion price of $0.75 per share. The Notes bear simple interest at the annual rate of 7%. Principal and accrued interest, to the extent not previously paid or converted, is due and payable on the maturity date. At the commitment date, the conversion price was greater than the fair value of the common stock. Accordingly, no beneficial conversion feature was recorded. The Company incurred approximately $92,000 of debt discount related to the detachable warrants issued with the 2017 Notes, which was amortized over the term of the notes.

On June 14, 2017, the Company’s Board of Directors approved a modification in the warrant terms issued in connection with the Notes. The warrant coverage was increased from 25% to 50% and the exercise price of the warrant was reduced from $1.35 to $1.00 per share. On June 19, 2017, in connection with the new terms, the Company issued an incremental 383,333 warrant shares to these previous Note holders.

During the nine months ended February 28, 2018, the Company issued approximately $4.89 million in aggregate principal of additional Notes and related warrants, as described above. At the commitment dates, the Company determined that the conversion feature related to these Notes to be beneficial to the investors. As a result, the Company determined the intrinsic value of the beneficial conversion feature utilizing the fair value of the underlying common stock on the commitment dates and the effective conversion price after discounting the Notes for the fair value of the related warrants.

In connection with the sale of the Notes during the nine months ended February 28, 2018 and year ended May 31, 2017, detachable common stock warrants to purchase a total of 4,025,656 common shares, with an exercise price of $1.00 per share and a five-year term were issued to the Note holders. The Company determined the fair value of the warrants at issuance using the Black-Scholes option pricing model utilizing certain weighted average assumptions, such as expected stock price volatility, expected term of the warrants, risk-free interest rates and expected dividend yield at the grant date.

The fair value of the warrants, coupled with the beneficial conversion features, were recorded as a debt discount to the Notes and a corresponding increase to additional paid-in capital was amortized over the life of the Notes. The Company incurred debt discount of approximately $1.6 million during the nine months ended February 28, 2018, related to the beneficial conversion feature and detachable warrants issued with the Notes. During the year ended May 31, 2017 the Company incurred debt discount of approximately $92,000 related to the detachable warrants issued with the Notes. Accordingly, the Company recognized approximately $1.6 million and $-0-, of non-cash debt discount during the nine months ended February 28, 2018 and year ended May 31, 2017, respectively. In connection with the Notes, the Company incurred direct issuance costs of approximately $0.4 million during the nine months ended February 28, 2018. The issuance costs were amortized over the term of the Notes and accordingly, the Company recognized approximately $0.4 million of debt issuance costs during the nine months ended February 28, 2018.

On January 31, 2018, in connection with a registered direct equity offering, as fully described in Note 11, the Notes in an aggregate principal amount of $5,788,500, plus accrued unpaid interest of approximately $243,000 were sold for 12,062,728 shares of common stock and the exercise price of the original detachable warrants was reduced from $1.00 to $0.75 per share.
