7. Stock-based Compensation

 

The Company currently has one equity incentive plan (the “2010 Plan”), which provides for awards in the form of restricted shares, stock units, stock options or stock appreciation rights to the Company’s employees, officers, directors and consultants. Prior to SemiLEDs’ initial public offering, the Company had another stock-based compensation plan (the “2005 Plan”), but awards are made from the 2010 Plan after the initial public offering. Options outstanding under the 2005 Plan continue to be governed by its existing terms.

 

A total of 3,849 thousand shares of common stock was reserved for issuance under the 2005 Plan and 2010 Plan. As of February 28, 2014 and August 31, 2013, SemiLEDs had reserved 2,008 thousand and 2,654 thousand shares of common stock for issuance under the equity incentive plans. In January 2014, SemiLEDs’ board of directors approved an amendment to the 2010 Plan that, subject to stockholders approval, increases the number of shares authorized for issuance under the plan by an additional 2,500 thousand shares.

 

During fiscal 2013, SemiLEDs granted options for 100 thousand shares of SemiLEDs’ common stock and 1,195 thousand restricted stock units to the Company’s executives and employees. These options and stock units vest over four years at a rate of 25% on each anniversary of the vesting start date and the options have a contractual term of ten years, subject to earlier expiration in the event of the holder’s termination. The exercise price of stock options and the grant date fair value of stock units were equal to the closing price of the common stock on the date of grant. In addition, in February 2013, SemiLEDs granted 211 thousand restricted stock units to its directors that vest 100% on the earlier of the first anniversary of the vesting start date of February 6, 2013 and the date of the next annual meeting. The grant-date fair value of the restricted stock units was $0.71 per unit. Each restricted stock unit represents the contingent right to one share of SemiLEDs’ common stock.

 

The grant date fair value of stock options is determined using the Black-Scholes option-pricing model. The Black-Scholes option-pricing model requires inputs including the market price of SemiLEDs’ common stock on the date of grant, the term that the stock options are expected to be outstanding, the implied stock volatilities of several of the Company’s publicly-traded peers over the expected term of stock options, risk-free interest rate and expected dividend. Each of these inputs is subjective and generally requires significant judgment to determine. The grant date fair value of stock units is based upon the market price of SemiLEDs’ common stock on the date of the grant. This fair value is amortized to compensation expense over the vesting term.

 

Stock-based compensation expense is recorded net of estimated forfeitures such that expense is recorded only for those stock-based awards that are expected to vest. A forfeiture rate is estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from initial estimates. A forfeiture rate of zero is estimated for stock-based awards with vesting term that is less than or equal to one year from the date of grant.
