19. Stock-based Compensation

The Company measures stock-based compensation expense for all stock-based compensation awards based on the grant-date fair value and recognizes the cost in the financial statements over the employee requisite service period.

The following table summarizes the consolidated stock-based compensation expense, by type of awards for the years ended December 31:

	For the Years Ended
	December 31, 2014		December 31, 2013
Employee stock options	$	332	$	575
Restricted stock grants		24		-
Total stock-based compensation expense	$	356	$	575

The following table summarizes the consolidated stock-based compensation by line items for the years ended December 31:

	For the Years Ended
	December 31, 2014		December 31, 2013
General and administrative	$	326	$	429
Sales, marketing and customer service		30		100
Engineering, design and product management		-		46
Total stock-based compensation expense		356		575
Tax effect on stock-based compensation expense		-		-
Total stock-based compensation expense after income taxes	$	356	$	575

As stock-based compensation expense recognized in the consolidated statements of operations is based on awards ultimately expected to vest, it has been reduced for estimated forfeitures. Forfeitures are required to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates.

Determining Fair Value

Valuation and Amortization Method — The Company estimates the fair value of service-based and performance-based stock options granted using the Black-Scholes option-pricing formula. The fair value is then amortized on a straight-line basis over the requisite service periods of the awards, which is generally the vesting period. In the case of performance-based stock options, amortization does not begin until it is determined that meeting the performance criteria is probable. Service-based and performance-based options typically have a five to ten year life from date of grant and vesting periods of three to four years.

Expected Term — The Company’s expected term represents the period that the Company’s stock-based awards are expected to be outstanding. For awards granted subject only to service vesting requirements, the Company utilizes the simplified method for estimating the expected term of the stock-based award, instead of historical exercise data. For its performance-based awards, the Company has determined the expected term life to be five years based on contractual life and the seniority of the recipient.

Expected Volatility —The Company uses historical volatility of the price of its common shares to calculate the volatility for its granted options.

Expected Dividend — The Company has never paid dividends on its common shares and currently does not intend to do so, and accordingly, the dividend yield percentage is zero for all periods.

Risk-Free Interest Rate — The Company bases the risk-free interest rate used in the Black-Scholes valuation model upon the implied yield curve currently available on U.S. Treasury zero-coupon issues with a remaining term equal to the expected term used as the assumption in the model.

Assumptions used in the determination of the fair value of share-based payment awards using the Black-Scholes model for stock option grants during the years ended December 31 were as follows:

	For the Years Ended
	December 31, 2014					December 31, 2013
Expected term				4					3.75
Risk-free interest rate		1.39	%	-	1.85%		0.95	%	-	1.2%
Expected volatility		141	%	-	144%		106	%	-	118%
Expected dividend yield				0%					0%

Equity Incentive Plan

On November 15, 2006, subject to approval of the stockholders, the Company adopted the 2006 Equity Incentive Plan (the “Plan”) which permits the Company to grant stock options to directors, officers or employees of the Company or others to purchase shares of Common Stock of the Company through awards of incentive and nonqualified stock options (“Option”), stock (“Restricted Stock” or “Unrestricted Stock”) and stock appreciation rights (“SARs”). The Plan was approved by the stockholders on February 7, 2007.

The Company has granted time-based share options and restricted stock under the Plan to directors, officers, employees and individual consultants of the Company. The time-based options generally vest 25% annually and expire three to ten years from the date of grant. Total number of shares reserved and available for grant and issuance pursuant to this Plan is equal to 9% of the number of outstanding shares of the Company. Shares issued under the Plan will be drawn from authorized and unissued shares or shares now held or subsequently acquired by the Company. Outstanding shares of the Company shall, for purposes of such calculation, include the number of shares of stock into which other securities or instruments issued by the Company are currently convertible (e.g., convertible preferred stock, convertible debentures, or warrants for Common Stock), but not outstanding options to acquire stock. At December 31, 2014 there were 29,624,317 shares available for grant under the plan (9% of the outstanding shares of 568,847,967 plus outstanding warrants of 35,300,000 shares, plus 17,500,000 shares if converted from the convertible promissory note, less options outstanding and exercised since inception).

The exercise price of any Option will be determined by the Company when the Option is granted and may not be less than 100% of the fair market value of the shares on the date of grant, and the exercise price of any incentive stock option granted to a stockholder with a 10% or greater shareholding will not be less than 110% of the fair market value of the shares on the date of grant. The exercise price per share of a SAR will be determined by the Company at the time of grant, but will in no event be less than the fair market value of a share of Company’s stock on the date of grant.
