Share-Based Compensation - Note 11

11. SHARE-BASED COMPENSATION

We use the straight-line attribution method to allocate the fair value of share-based compensation awards over the requisite service period for each award. The valuation of and accounting for share-based awards includes a number of complex and subjective estimates. These estimates include, but are not limited to, the future volatility of our stock price, future stock option exercise behaviors, estimated employee turnover, and award forfeiture rates.

Description of Incentive Plan

Our 2013 Incentive Plan has 10.8 million shares authorized, of which 3.0 million shares were available for awards as of December 31, 2018.

Options Valuation Methodology and Assumptions

We use the Black-Scholes option valuation model to determine the fair value of options granted and use the closing price of our common stock as the fair market value of our stock on that date.

We consider historical stock price volatilities, volatilities of similar companies and other factors in determining estimates of future volatilities.

We use historical lives, including post-termination exercise behavior, as the basis for estimating expected lives.

Risk-free rates are based on the U.S. Treasury Yield Curve, as published by the U.S. Treasury.

The following table summarizes the weighted-average valuation assumptions and weighted-average grant date fair value of options granted during the periods shown below:

		Year Ended December 31,
Assumptions (weighted-average)		2018		2017
Volatility		73%		79%
Expected term (in years)		3.2		4.0
Risk-free rate		2.8%		1.6%
Expected dividends		0.0%		0.0%
Pre-vest forfeiture rate		8.5%		8.5%
Grant date fair value of options granted	$	0.58	$	1.03

The intrinsic value of options exercised during the year ended December 31, 2017 was $40,000. No options were exercised during the year ended December 31, 2018.

The total grant date fair value of options vested during the years ended December 31, 2018 and 2017 was $958,000 and $1.0 million, respectively. As of December 31, 2018, our unrecognized share-based compensation was $1.6 million related to options, which we plan to amortize over the next 2.3 years.

On September 30, 2018, we issued 583,333 performance stock units to our executives.  The performance criteria is the achievement of the Company's share price of $2.50 sustained for 60 of trailing 90 days before the PSUs are earned ("Earned PSUs").  To the extent the PSUs become Earned PSUs they shall be eligible to vest as to one-third (1/3) of the PSUs subject to the Award on the each of the first three (3) anniversaries of June 5, 2018, subject to the executive's continuous employment on the applicable vesting date.  If there are outstanding but unearned PSUs as of a vesting date and the PSUs become Earned PSUs prior to the next vesting date the Earned PSUs that would have vested on any earlier vesting date shall become immediately vested and deliverable.  The PSUs are valued using a binomial option pricing model using the following inputs: stock price, volatility, and risk- free interest rates. We issued 291,667 RSUs to our executives that vest one-third on each of the first three anniversaries of June 5, 2018. We also issued 180,000 RSUs to members of the board.  The members of the board vest ownership in the RSUs on the earlier of the day prior to the date of the Company's annual meeting of shareholders following the date of grant, or one year from the grant date, provided the member of the board continues to serve as a director on the vesting date.

As of December 31, 2018, our unrecognized share-based compensation related to the RSUs was $607,000, which we plan to amortize over the next 2.1 years. As of December 31, 2018, our unrecognized share-based compensation related to the PSUs was $16,000, which we plan to amortize over the next 2.4 years.
