Stock-Based Compensation

Calyxt, Inc. Equity Incentive Plans

The Company adopted the Calyxt, Inc. Equity Incentive Plan, or the Initial Plan, which allows for the grant of stock options to attract and retain highly qualified employees. In June 2017, the Company also adopted an omnibus incentive plan, or the Omnibus Plan, under which the Company granted stock options and restricted stock units to certain of the Company’s employees and nonemployees, as well as certain employees and nonemployees of Cellectis.

The options granted under the Initial Plan and the Omnibus Plan, which were only eligible for exercise following the completion of the IPO on July 25, 2017, have an exercise price equal to the estimated fair value of the stock at the grant date for the Omnibus Plan and the grant date for the Initial Plan, respectively.

 

The following table presents stock-based compensation expense included in the Company’s condensed statements of operations (in thousands) for stock options and restricted stock unit awards under the plans:

For accounting purposes, the Company treats stock-based compensation awards granted to employees of Cellectis as deemed dividends to Cellectis, which are recorded quarterly. The Company recorded $663 thousand and $1.4 million and $69 thousand and $69 thousand in deemed dividends to Cellectis in the three and six months ended June 30, 2018 and 2017, respectively, for RSUs and stock options granted to employees of Cellectis.

Equity instruments issued to non-employees include RSUs and options to purchase shares of the Company’s common stock. These RSUs and options vest over a certain period during which services are provided. The Company expenses the fair market value of the awards over the period in which the related services are received. Unvested awards are remeasured to fair value until they vest.

The weighted average grant date fair value for stock options granted during the six months ended June 30, 2018 and 2017 was $10.27 and $2.41, respectively. The total fair value of stock options vested during the six months ended June 30, 2018 and 2017 was $2.2 million and $0, respectively. The aggregate intrinsic value of stock options exercised during the six months ended June 30, 2018 and 2017 was $5.2 million and $0, respectively. At June 30, 2018, the total unrecognized stock-based compensation expense related to non-vested stock options is approximately $3.7 million, which is expected to be recognized over a weighted-average period of 4.2 years.

The fair value of each stock option is estimated using the Black-Scholes option pricing model at each measurement date. The fair value of stock options under the Black-Scholes model requires management to make assumptions regarding projected employee stock option exercise behaviors, risk-free interest rates, volatility of the stock price, and expected dividends. The awards currently outstanding were granted with vesting terms between two and six years. Certain awards contained a 25% acceleration vesting clause upon a triggering event or initial public offering as defined in the Initial Plan.

 

The Company has not historically paid dividends to its stockholders and currently does not anticipate paying any dividends in the foreseeable future. As a result, the Company has assumed a dividend yield of 0%. The risk-free interest rate is based upon the rates of U.S. Treasury bills with a term that approximates the expected life of the option. The Company uses the simplified method, or the lattice method when appropriate, to reasonably estimate the expected life of its option awards. Expected volatility is based upon the volatility of comparable public companies.

The following table provides the assumptions used in the Black-Scholes model for the stock option awards:
