SHAREHOLDERS' EQUITY

Preferred Stock – We are authorized to issue 50,000,000 shares of preferred stock, par value $0.001 per share. In October 2019, the Company designated 5,000,000 of these shares as 8% Series A Cumulative Convertible Preferred Stock. Our 8% Series A Cumulative Convertible Preferred Stock ranks senior to our common stock for liquidation or dividend provisions and are entitled to receive cumulative cash dividends at an annual rate of 8% payable monthly in arrears for the prior month. The Company reviewed ASC 480 – Distinguishing Liabilities from Equity in order to determine the appropriate accounting treatment for the preferred stock and determined that the preferred stock should be treated as equity. There were 500,000 shares of 8% Series A Cumulative Convertible Preferred Stock issued and outstanding at December 31, 2019.

The total amount of dividends declared and paid were $67,000 and $67,000, respectively, for the three months ended December 31, 2019.

Common Stock – We are authorized to issue 150,000,000 shares of common stock, par value $0.001 per share. There were 27,720,356 shares of common stock issued and outstanding at December 31, 2019 and September 30, 2019, respectively.

In December 2019 we granted an aggregate of 280,000 common stock options to two executives. The options vest 1/3 on January 1, 2020, 1/3 on January 1, 2021 and 1/3 on January 1, 2022, have an exercise price of $3.15 per share and a term of five years. We have recorded an expense for the options of $190,776 for the three months ended December 31, 2019.

No options were issued in the three months ended December 31, 2018.

The expected volatility rate was estimated based on comparison to the volatility of a peer group of companies in similar industries. The expected term used was the full term of the contract for the issuances. The risk-free interest rate for periods within the contractual life of the option is based on U.S. Treasury securities. The pre-vesting forfeiture rate of zero is based upon the experience of the Company. As required under ASC 718, we will adjust the estimated forfeiture rate to our actual experience. Management will continue to assess the assumptions and methodologies used to calculate estimated fair value of share-based compensation. Circumstances may change and additional data may become available over time, which could result in changes to these assumptions and methodologies, and thereby materially impact our fair value determination.
