4.	Stock Plans and Stock Based Compensation

The Company has certain stock option plans under which it awards incentive and non-qualified stock options to employees, officers, and outside directors.

On September 17, 2015, the Company granted an aggregate of 12,000 non-qualified stock options (“NQSOs”) from the Company’s 2003 Outside Directors Stock Plan (“2003 Stock Plan”) to five of the seven re-elected directors at our Annual Meeting of Stockholders held on September 17, 2015. Two of the directors are not eligible to receive options under the 2003 Stock Plan as they are employees of the Company or its subsidiaries. Dr. Centofanti is the Company’s Chief Executive Officer and Mr. John Climaco is an Executive Vice President of Perma-Fix Medical S.A. (effective June 2, 2015), the Company’s majority-owned Polish subsidiary. The NQSOs granted were for a contractual term of ten years with a vesting period of six months. The exercise price of the NQSOs was $4.19 per share, which was equal to the Company’s closing stock price the day preceding the grant date, pursuant to the 2003 Stock Plan.

As of September 30, 2015, the Company had an aggregate of 55,000 employee stock options outstanding (from the 2010 Stock Option Plans), of which 18,333 are vested. The weighted average exercise price of the 18,333 outstanding and fully vested employee stock options is $5.00 with a remaining weighted contractual life of 4.8 years. Additionally, the Company had an aggregate of 163,200 outstanding director stock options (from the 2003 Plans), of which 151,200 are vested. The weighted average exercise price of the 151,200 outstanding and fully vested director stock options is $8.89 with a remaining weighted contractual life of 4.8 years.

The summary of the Company’s total Stock Option Plans as of September 30, 2015, and 2014, and changes during the periods then ended, are presented below. The Company’s Plans consist of the 2004 and 2010 Stock Option Plans and the 2003 Stock Plans:

The Company estimates fair value of stock options using the Black-Scholes valuation model. Assumptions used to estimate the fair value of stock options granted include the exercise price of the award, the expected term, the expected volatility of the Company’s stock over the option’s expected term, the risk-free interest rate over the option’s expected term, and the expected annual dividend yield. The fair value of the options granted during the nine months ended September 30, 2015 and 2014 and the related assumptions used in the Black-Scholes option model used to value the options granted were as follows (No options were granted to employees during the nine months ended September 30, 2015):

	Outside Director Stock Options Granted
	September 30, 2015		September 30, 2014
Weighted-average fair value per share		$2.84		$2.73
Risk -free interest rate (1)		2.21%		2.63%
Expected volatility of stock (2)		57.98%		59.59%
Dividend yield		None		None
Expected option life (3) (years)		10.0		10.0

	Employee Stock Option Granted
	as of September 30, 2014
Weighted-average fair value per share		$2.88
Risk -free interest rate (1)		1.91%
Expected volatility of stock (2)		61.84%
Dividend yield		None
Expected option life (3) (years)		6.0

(1)

The risk-free interest rate is based on the U.S. Treasury yield in effect at the grant date over the expected term of the option.

(2)

The expected volatility is based on historical volatility from our traded Common Stock over the expected term of the option.

)

The expected option life is based on historical exercises and post-vesting data.

The following table summarizes stock-based compensation recognized, which is included in selling, general and administrative expenses (“SG&A”) in the accompanying Consolidated Statements of Operations, for the three and nine months ended September 30, 2015 and 2014 for our employee and director stock options.

	Three Months Ended				Nine Months Ended
Stock Options	September 30,				September 30,
	2015		2014		2015		2014
Employee Stock Options	$	13,000	$	12,000	$	39,000	$	(27,000	)
Director Stock Options		2,000		3,000		23,000		25,000
Total	$	15,000	$	15,000	$	62,000	$	(2,000	)

The Company recognized stock-based compensation expense using a straight-line amortization method over the requisite service period, which is the vesting period of the stock option grant. ASC 718, “Compensation – Stock Compensation” requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. The Company has generally estimated forfeiture rates based on historical trends of actual forfeitures. When actual forfeitures vary from our estimates, the Company recognizes the difference in compensation expense in the period the actual forfeitures occur or when options vest. The total stock-based compensation expense for the nine months ended September 30, 2014 included a reduction in expense of approximately $54,000 resulting from the forfeiture of options by Mr. Jim Blankenhorn, our Chief Operating Officer (“COO”), who voluntarily resigned from the Company effective March 28, 2014. The COO was granted an option from the Company’s 2010 Stock Option Plan on July 25, 2011, to purchase up to 60,000 shares of the Company’s Common Stock at $7.85 per share. The options had a six year contractual term with one-third yearly vesting over a three year period.

As of September 30, 2015, the Company has approximately $117,000 of total unrecognized compensation cost related to unvested options, of which $30,000 is expected to be recognized in remaining 2015, $68,000 in 2016, with the remaining $19,000 in 2017.

During the nine months ended September 30, 2015, the Company issued a total of 55,459 shares of our Common Stock under our 2003 Plan to our outside directors as compensation for serving on our Board of Directors. The Company has recorded approximately $216,000 in compensation expenses (included in SG&A) in connection with the issuance of shares of our Common Stock to our outside directors. Also, an outside director exercised 3,423 options from the 2003 Stock Plan for the purchase of 3,423 shares of the Company’s Common Stock at $2.79 per share.
