Stock-Based Compensation

6 Months Ended

Jun. 30, 2014

The Company has historically issued stock-based compensation in the form of nonvested restricted stock, stock options and stock appreciation rights (SARs). During the first six months of 2014, stock-based compensation was issued in the form of nonvested restricted stock and SARs. The stock-based compensation expense that has been charged against income was $2.2 million and $1.5 million in the three month periods ended June 30, 2014 and 2013, respectively, and $4.5 million and $2.7 million in the six months ended June 30, 2014 and 2013, respectively.

Nonvested stock awards generally vest in 4 to 7 years and contain restrictions as to transferability, sale, pledging, or assigning, among others, prior to the end of the vesting period. Dividend and voting rights are conferred upon grant. A summary of the status of the Company’s nonvested share awards as of June 30, 2014, and changes during the six month period then ended, is presented below.



	Shares		Weighted Average Grant Date Fair Value
Nonvested at January 1, 2014	1,143,755		$34.27
Granted	181,448		44.59
Vested	(84,542	)	29.48
Forfeited	(22,491	)	39.05
Nonvested at June 30, 2014	1,218,170		$36.05

SARs and stock options are granted with exercise prices equal to the market price of the Company’s stock at the date of grant. SARs vest ratably over 4 years of continuous service and have 10-year contractual terms. All SARs must be settled in stock under provisions of the plan. Stock options, which have not been granted since 2005, vested ratably over 3 years of continuous service and also have 10-year contractual terms. In determining compensation cost, the Black-Scholes option-pricing model is used to estimate the fair value of SARs and options on date of grant. The current year per share average fair value and the model assumptions are shown in the table below.



Weighted per share average fair value at grant date		$9.26

Volatility	22.1		%
Risk-free interest rate	2.3		%

Disclosure may also include nature and general terms of such arrangements that existed during the period and potential effects of those arrangements on shareholders, effect of compensation cost arising from equity-based payment arrangements on the income statement, method of estimating the fair value of the goods or services received, or the fair value of the equity instruments granted, during the period, cash flow effects resulting from equity-based payment arrangements and, for registrants that accelerate vesting of out of the money share options, reasons for the decision to accelerate.
