Reverse Share Split

​

During September 2021, the total number of shares of common stock authorized by the Company was reduced from 900,000,000 shares of common stock, par $0.001, to 180,000,000 shares of common stock, par $0.001, and the number of shares of common stock held by each stockholder of the Company were consolidated automatically into the number of shares of common stock equal to the number of issued and outstanding shares of common stock held by each such stockholder immediately prior to the reverse split divided by five (5): effecting a five (5) old for one (1) new reverse stock split.

​

No fractional shares were issued in connection with the reverse split and all fractional shares were rounded up to the next whole share.  

​

Additionally, all options, warrants and other convertible securities of the Company outstanding immediately prior to the reverse split were adjusted by dividing the number of shares of common stock into which the options, warrants and other convertible securities are exercisable or convertible by five (5) and multiplying the exercise or conversion price thereof by five (5), all in accordance with the terms of the plans, agreements or arrangements governing such options, warrants and other convertible securities and subject to rounding to the nearest whole share.

​

All shares of common stock, options, warrants and other convertible securities and the corresponding price per share amounts have been presented to reflect the reverse split in all periods presented within this Form 10-Q.

The following table summarizes information about stock options outstanding and exercisable under the Company’s Stock Option Plan at September 30, 2021:

​

​

The Company uses the Black-Scholes option pricing model to determine the estimated fair value of options. The fair value of each option grant is determined on the date of grant and the expense is recorded on a straight-line basis and is included as a component of general and administrative expense in the consolidated statements of operations. The assumptions used in the model include expected life, volatility, risk-free interest rate, dividend yield and forfeiture rate. The Company’s determination of these assumptions are outlined below.

Expected life — The expected life assumption is based on an analysis of the Company’s historical employee exercise patterns.

Volatility — Volatility is calculated using the historical volatility of the Company’s common stock for a term consistent with the expected life.

Risk-free interest rate — The risk-free interest rate assumption is based on the U.S. Treasury rate for issues with remaining terms similar to the expected life of the options.

Dividend yield — Expected dividend yield is calculated based on cash dividends declared by the Board for the previous four quarters and dividing that result by the average closing price of the Company’s common stock for the quarter. The Company has not declared a dividend to date.

Forfeiture rate — The Company does not estimate a forfeiture rate at the time of the grant due to the limited number of historical forfeitures. As a result, the forfeitures are recorded at the time the grant is forfeited.

​

The following assumptions were used to value the awards granted during the nine months ended September 30, 2021:

​

​

Stock-based compensation expense for the three months ended September 30, 2021 and 2020 was $210 thousand and $88 thousand, respectively, and $818 thousand and $456 thousand for the nine months ended September 30, 2021 and 2020, respectively. As of September 30, 2021, there was approximately $925 thousand of total unrecognized compensation cost related to 378,092 unvested stock options that is expected to be recognized over a weighted-average remaining vesting period of 2.2 years.

​
