Restricted Stock

The following table summarizes our restricted stock activity:



	Restricted Stock		Weighted Average Grant Date Fair Value Per Share
Nonvested as of December 31, 2017	213,982		$	3.53
Granted	160,146		1.13

Forfeited	(45,992	)	4.86
Nonvested as of June 30, 2018	311,136		$	1.92

The cost of the awards is determined using the fair market value of the Company’s common stock on the date of the grant, and compensation is recognized on a straight-line basis over the requisite vesting period.

As of June 30, 2018, there was $0.2 million of total unrecognized compensation expense related to non-vested restricted stock granted under our Stock Plans. That expense is expected to be recognized over a weighted average period of 1.2 years.

Stock Appreciation Rights

The Company had less than 0.1 million Stock Appreciation Rights (“SARs”) outstanding at December 31, 2017. The performance targets were not met for the outstanding SARs and, as such, were subsequently canceled. As of June 30, 2018, the Company no longer has any outstanding SARs.
