13. STOCK-BASED COMPENSATION

Pursuant to the Company’s 2019 Omnibus Equity Incentive Plan adopted and approved in 2019 (“ 2019 Plan”), awards under the 2019 Plan is limited in the aggregate to 2,068,398 shares of our common stock, inclusive of the awards that were previously issued and outstanding under the Company’s 2007 Equity Incentive Plan, as amended (the “2007 Plan”). Upon adoption and approval of the 2019 Plan, the 2007 Plan was frozen, no new awards will be granted under the 2007 Plan, and outstanding awards under the 2007 Plan will continue to be governed by the terms and condition of the 2007 Plan and applicable award agreement. As of December 31, 2020, the number of shares of the Company’s common stock available for grant of stock options and issuance under the 2019 Plan is 515,648 shares.

The fair value of each option award is estimated on the date of grant using the Black-Scholes option-pricing model. The risk free rate is based on the yield-to-maturity in continuous compounding of the US Government Bonds with the time-to-maturity similar to the expected tenor of the option granted, volatility is based on the annualized historical stock price volatility of the Company, and the expected life is based on the historical option exercise pattern.

On April 1, 2019, the Company granted to one employee options to purchase 30,000 shares of the Company’s common stock, at an exercise price of $4.55 per share and the options vested immediately. The options were valued at $45,900 fair value, with assumed 45.26% volatility, a four-year expiration term with an expected tenor of 1.60 years, a risk free rate of 2.37% and no dividend yield.

For the year ended December 31, 2020 and 2019, total compensation costs for options issued recorded in the consolidated statement of comprehensive income (loss) were $0 and $45,900. There were no related tax benefits as a full valuation allowance was recorded in the years ended December 31, 2020 and 2019.
