SHARE-BASED COMPENSATION

We recognize share-based compensation for all stock options granted over the requisite service period using the fair value of these grants as estimated at the date of grant using the Black-Scholes pricing model, and all restricted stock granted over the requisite service period using the market value of our publicly-traded common stock on the date of grant.

Share-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 100% of the fair market value of the shares of common stock on the date granted and the term of an ISO may not be more than ten years. The exercise price of any non-qualified options granted will not be less than 100% of the fair market value of the shares of common stock on the date granted unless so determined by the Committee.

In May 2012, our stockholders approved the 2012 Stock Incentive Plan ("the 2012 Plan") pursuant to which 1,500,000 shares of our common stock were made available to grant as share-based payments to employees, officers, directors or consultants. As of December 31, 2013, there were 1,140,000 shares available for future grants under the 2012 Plan. The individual restricted stock and option grant awards vest over periods up to five years. The term of the options under the 2012 Plan is up to five years from the date of grant.

In May 2005, our stockholders approved the NHI 2005 Stock Option Plan ("the 2005 Plan") pursuant to which 1,500,000 shares of our common stock were made available to grant as share-based payments to employees, officers, directors or consultants. As of December 31, 2013, there were 20,635 shares available for future grants under the 2005 Plan. The individual restricted stock and option grant awards vest over periods up to ten years. The term of the options outstanding under the 2005 Plan is up to ten years from the date of grant.

The NHI 1997 Stock Option Plan (“the 1997 Plan”) provides for the granting of options to key employees and directors of NHI to purchase shares of common stock at a price no less than the market value of the stock on the date the option is granted. As of December 31, 2013, no shares were available for future grants under this plan. The term of the options outstanding under the 1997 Plan is five years from the date of the grant.

Compensation expense is recognized only for the awards that ultimately vest. Accordingly, forfeitures that were not expected may result in the reversal of previously recorded compensation expense. The compensation expense reported for the year ended December 31, 2013 was $2,339,000, all of which related to outstanding stock options, as compared to $2,168,000 for the year ended December 31, 2012, consisting of $2,167,000 for stock options and $1,000 for restricted stock and is included in general and administrative expense in the Consolidated Statements of Income.

Determining Fair Value of Option Awards

The fair value of each option award was estimated on the grant date using the Black-Scholes option valuation model with the weighted average assumptions indicated in the following table. Each grant is valued as a single award with an expected term based upon expected employee and termination behavior. Compensation cost is recognized on the graded vesting method over the requisite service period for each separately vesting tranche of the award as though the award were, in substance, multiple awards. The expected volatility is derived using daily historical data for periods preceding the date of grant. The risk-free interest rate is the approximate yield on the United States Treasury Strips having a life equal to the expected option life on the date of grant. The expected life is an estimate of the number of years an option will be held before it is exercised.

Stock Options

The weighted average fair value per share of options granted was $6.41, $6.36 and $9.91 for 2013, 2012 and 2011, respectively. The fair value of each grant is estimated on the date of grant using the Black-Scholes option-pricing model with the following weighted average assumptions:



	2013	2012	2011
Dividend yield	4.5%	6.0%	5.9%
Expected volatility	23.8%	32.0%	4.6%
Expected lives	2.8 years	3.9 years	3.9 years
Risk-free interest rate	0.35%	0.32%	1.11%
