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 June 30, 2020, the number of shares of the Company’s common stock available for grant of stock options and issuance under the 2019 Plan is 989,698 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.
