Note 4 – Convertible Instruments

Series B Convertible Preferred Stock

During fiscal 2010, the Company issued 400,000 shares of Series B, $0.001 par value Convertible Preferred Stock (“Series B”) at $5.00 per share for cash proceeds totaling $2,009,000, of which 92,100 shares remain outstanding at August 31, 2018. Each share of the Series B is convertible into ten shares of the Company’s $0.001 par value 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 $6,000,000. 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. As of August 31, 2018 and May 31, 2018, the undeclared, accrued dividends were approximately $199,200 and $199,000, respectively, or 398,400 and 387,000 shares of common stock, respectively.

Short-term Convertible Notes

During the year ended May 31, 2018, the Company issued approximately $4.89 million in aggregate principal of short-term Convertible Notes, with a maturity date of January 31, 2018, and related warrants to investors for cash. The principal amount of the short-term Convertible Notes, including any accrued but unpaid interest thereon, was 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 short-term Convertible Notes bore 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 Company determined that the conversion feature related to these short-term Convertible 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 short-term Convertible Notes for the fair value of the related warrants.

In connection with the sale of the short-term Convertible Notes, 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 investors. 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 short-term Convertible Notes and a corresponding increase to additional paid-in capital was amortized over the term of the short-term Convertible Notes. The Company incurred debt discount of approximately $1.5 million related to the beneficial conversion feature and detachable warrants issued with the short-term Convertible Notes during the year ended May 31, 2018.
