Disclosure of Compensation Related Costs, Share-based Payments [Abstract]

In June 2019, the Company’s stockholders approved an amendment to the Company’s Amended and Restated 2014 Equity Incentive Plan (the “2014 Plan”), to increase the number of shares available for grant by 3,500 shares. As of June 30, 2019, the total shares authorized for grant under the 2014 Plan was 12,614, of which 4,015 were available for future grants.

As of June 30, 2019, total unrecognized compensation cost related to unvested stock options was $4,849. This amount is expected to be recognized as stock-based compensation expense in the Company’s condensed consolidated statements of operations and comprehensive income over the remaining weighted average vesting period of 2.84 years.

The per-share fair value of each stock option was determined on the date of grant using the Black-Scholes option pricing model using the following assumptions:



	Three Months Ended June 30,				Six Months Ended June 30,
	2019		2018		2019		2018
Dividend yield	—		—		—		—

Expected term (in years)	6		6-10		6		6-10
Volatility	102	%	89	%	102	%	89	%

Restricted Stock Units

The Company issues restricted stock units (“RSUs”) to employees and non-employee service providers as permitted by the 2014 Plan. Each RSU represents the right to receive one share of the Company’s common stock upon vesting and subsequent settlement. The fair value of RSUs is determined based on the closing price of the Company’s common stock on the date of grant.

RSU activity for the period ended June 30, 2019 is summarized below:



	Number of Shares		Weighted- Average Grant Date Fair Value
Unvested as of December 31, 2018	278		$	1.83
Granted	560		1.64
Vested	(563	)	1.65
Forfeited	(36	)	2.02
Unvested at June 30, 2019	239		$	1.78

As of June 30, 2019, $326 of total unrecognized compensation expense related to unvested RSUs was expected to be recognized over a weighted average period of 2.98 years.
