– Stock–Based Compensation

NHC recognizes stock–based compensation expense for all stock options and restricted stock granted over the requisite service period using the fair value for these grants as estimated at the date of grant either using the Black–Scholes pricing model for stock options or the quoted market price for restricted stock.

The 2005 and 2010

Stock–Based

Compensation Plans

The Compensation Committee of the Board of Directors (“the Committee”) has the authority to select the participants to be granted options; to designate whether the option granted is an incentive stock option (“ISO”), a non–qualified option, or a stock appreciation right; to establish the number of shares of common stock that may be issued upon exercise of the option; to establish the vesting provision for any award; and to establish the term any award may be outstanding. The exercise price of any ISO’s granted will not be less than the fair market value of the shares of common stock on the date granted and the term of an ISO may not be any more than ten years. The exercise price of any non–qualified options granted will not be less than the fair market value of the shares of common stock on the date granted unless so determined by the Committee.

In May 2005, our stockholders approved the 2005 Stock Option, Employee Stock Purchase, Physician Stock Purchase and Stock Appreciation Rights Plan (“the 2005 Plan”) pursuant to which 1,200,000 shares of our common stock were available to grant as stock–based payments to key employees, directors, and non–employee consultants. The shares granted during the six months ended June 30, 2016 consisted of 45,000 shares to the Directors of the Company. At June 30, 2016, 131,276 shares were available for future grants under the 2005 Plan.

In May 2010, our stockholders approved the 2010 Omnibus Equity Incentive Plan (“the 2010 Plan”) pursuant to which 1,200,000 shares of our common stock were available to grant as stock–based payments to key employees, directors, and non–employee consultants. In May 2015, our stockholders voted to amend the 2010 Plan to increase the number of shares of our common stock authorized under the Plan from the original 1,200,000 shares to 2,575,000 shares. The shares granted during the six months ended June 30, 2016 consisted of 12,120 shares through the Employee Stock Purchase Plan. At June 30, 2016, 1,750,494 shares were available for future grants under the amended 2010 Plan.

Compensation expense is recognized only for the awards that ultimately vest. Stock–based compensation totaled $208,000 and $654,000 for the three months ended June 30, 2016 and 2015, respectively. Stock–based compensation totaled $494,000 and $1,132,000 for the six months ended June 30, 2016 and 2015, respectively. Stock–based compensation is included in “Salaries, wages and benefits” in the interim condensed consolidated statements of income.
