Stockholders' Equity Note [Abstract] |
Shareholders' Equity | 11. SHAREHOLDERS’ EQUITY Warrants In December 2016, the Company completed a registered direct offering of 100,000 shares of common stock at a net gross price of $15.00 per share. Concurrently, the investors received warrants to purchase 100,000 shares of common stock of the Company at an exercise price of $20.05 per share, for a period of five years from the final closing date of June 21, 2017. The warrants include anti-dilution rights. The total net proceeds received by the Company were approximately $1.32 million. The fair value of the warrants upon issuance were $1.24 million, with the remaining $0.08 million being attributed to common stock. On September 29, 2020, the Company received proceeds of $565 thousand related to the exercise of warrants to purchase 50,000 shares of common stock. The warrants have been classified as liabilities due to features in the warrant agreement that give the warrant holder an option to require the Company to redeem the warrant at a calculated fair value in the event of a “Fundamental Transaction,” as defined in the warrant agreement. The fair value of the remaining warrants to purchase 50,000 shares of common stock was $115 thousand and $95 thousand at March 31, 2021 and December 31, 2020, respectively. Pursuant to the original warrant agreement, as a result of common stock issuances at various prices, the warrant exercise price has been reduced from its original $20.50 exercise price to the floor price of $3.92, which is the exercise price of the warrants at March 31, 2021. Stock Options From time to time, the Company may grant stock options under its incentive plan covering shares of common stock to employees of the Company. Stock options, when exercised, are settled through the payment of the exercise price in exchange for new shares of stock underlying the option. These awards typically expire ten years from the grant date. For the three months ended March 31, 2021 and 2020, there was no compensation expense related to stock options. As of December 31, 2019, all stock options had vested. No stock options were granted, exercised, or expired during the three months ended March 31, 2021 or 2020.
