Restricted Stock

Kforce's annual restricted stock grants made to executives and management are generally based on the extent by which annual long-term incentive performance goals, which are established by Kforce’s Compensation Committee during the first quarter of the year of performance, have been met, as determined by the Compensation Committee. Additionally, Kforce, with the approval of the Compensation Committee, grants restricted stock in varying amounts as determined appropriate during the year to retain executives and management. Restricted stock granted during the nine months ended September 30, 2015 will vest over a period of between one to ten years, with equal vesting annually.

During the three months ended March 31, 2014, the Firm modified all awards containing a performance-acceleration feature that were granted during the three months ended December 31, 2013, as follows: (1) eliminated the performance-acceleration feature and (2) changed the time-based vesting term to five years, with equal vesting annually. The total number of restricted shares impacted by this modification was 268 thousand, excluding already forfeited shares, and the number of employees impacted was 87. The total incremental compensation cost resulting from the modification was $109 thousand, which will be amortized on a straight-line basis over the requisite service period of the modified awards.

Restricted stock contain the same voting rights as other common stock and are included in the number of shares of common stock issued and outstanding. Restricted stock contain the right to forfeitable dividends in the form of additional shares of restricted stock at the same rate as the cash dividend on common stock and containing the same vesting provisions as the underlying award. The following table presents the activity for the nine months ended September 30, 2015 (in thousands, except per share amounts):



	Number of Restricted Stock		Weighted Average Grant Date Fair Value		Total Intrinsic Value of Restricted Stock Vested
Outstanding as of December 31, 2014	982		$	18.55
Granted	533		$	23.92
Forfeited/Canceled	(59	)	$	19.37
Vested	(145	)	$	18.08	$	3,484
Outstanding as of September 30, 2015	1,311		$	20.73

The fair market value of restricted stock is determined based on the closing stock price of Kforce’s common stock at the date of grant, and is amortized on a straight-line basis over the requisite service period. As of September 30, 2015, total unrecognized compensation expense related to restricted stock was $19.5 million, which will be recognized over a weighted average remaining period of 4.5 years.
