NOTE 11: INCENTIVE PLANS

SHARE-BASED COMPENSATION PLANS

Our 2006 Omnibus Long-term Incentive Plan (Plan) authorizes the granting of stock options, Stock-Only Stock Appreciation Rights (SOSARs) and other types of share-based awards to key salaried employees and nonemployee directors. The maximum number of shares that may be issued under the Plan is 11,900,000.

PERFORMANCE SHARES — Each performance share unit is equal to and paid in one share of our common stock, but carries no voting or dividend rights. The number of units ultimately paid for performance share awards may range from 0% to 200% of the number of units awarded on the date of grant. Payment is based upon our Total Shareholder Return (TSR) performance relative to the TSR performance of the S&P 500®. Awards vest on December 31 of the fourth year after date of grant. Vesting is accelerated upon reaching retirement age, death, disability, or change of control, all as defined in the award agreement. Nonvested units are forfeited upon termination for any other reason. Expense provisions referable to performance share awards amounted to $13,159,000 in 2015, $16,863,000 in 2014 and $16,159,000 in 2013.

The fair value of performance shares is estimated as of the date of grant using a Monte Carlo simulation model. The following table summarizes the activity for nonvested performance share units during the year ended December 31, 2015:



	Target	Weighted-average
	Number	Grant-date
	of Shares	Fair Value
Performance Shares
Nonvested at January 1, 2015	1,019,416	$ 53.16
Granted	231,730	74.85
Vested	(441,483)	46.22
Canceled/forfeited	(3,324)	67.28
Nonvested at December 31, 2015	806,339	$ 63.13

During 2014 and 2013, the weighted-average grant-date fair value of performance shares granted was $63.42 and $53.65, respectively.

The aggregate values for distributed performance share awards are based on the closing price of our common stock as of the distribution date. The aggregate values of distributed performance shares for the years ended December 31 are as follows:



in thousands	2015	2014	2013
Aggregate value of distributed
performance shares	$ 26,258	$ 0	$ 9,286

In addition to the performance shares granted above, we granted 14,000 restricted shares in February 2015 and 60,000 restricted shares in December 2013 to certain key executives. These shares cliff vest on the fourth anniversary of the grant date and have a grant-date fair value of $74.85 and $54.35, respectively. Expense provisions referable to restricted share awards amounted to $982,000 in 2015, $704,000 in 2014 and $35,000 in 2013.

STOCK OPTIONS/SOSARS — Stock options/SOSARs granted have an exercise price equal to the market value of our underlying common stock on the date of grant. The options/SOSARs vest ratably over 4 years and expire 10 years subsequent to the grant. Vesting is accelerated upon reaching retirement age, death, disability, or change of control, all as defined in the award agreement. Nonvested awards are forfeited upon termination for any other reason.

The fair value of stock options/SOSARs is estimated as of the date of grant using the Black-Scholes option pricing model. Compensation cost for stock options/SOSARs is based on this grant-date fair value and is recognized for awards that ultimately vest. The following table presents the weighted-average fair value and the weighted-average assumptions used in estimating the fair value of grants during the years ended December 31:



	2015	2014	2013
SOSARs
Fair value	$ 25.17	$ 21.94	$ 16.96
Risk-free interest rate	1.85%	2.40%	1.40%
Dividend yield	1.70%	1.64%	1.72%
Volatility	33.00%	33.00%	33.00%
Expected term	8.00 years	8.00 years	8.00 years

The risk-free interest rate is based on the yield at the date of grant of a U.S. Treasury security with a maturity period approximating the SOSARs expected term. The dividend yield assumption is based on our historical dividend payouts adjusted for current expectations of future payouts. The volatility assumption is based on the historical volatility and expectations about future volatility of our common stock over a period equal to the SOSARs expected term. The expected term is based on historical experience and expectations about future exercises and represents the period of time that SOSARs granted are expected to be outstanding.

A summary of our stock option/SOSAR activity as of December 31, 2015 and changes during the year are presented below:



			Weighted-average
			Remaining	Aggregate
	Number	Weighted-average	Contractual	Intrinsic Value
	of Shares	Exercise Price	Life (Years)	(in thousands)
Stock Options/SOSARs
Outstanding at January 1, 2015	4,786,305	$ 59.65
Granted	161,310	79.41
Exercised	(1,890,028)	63.48
Forfeited or expired	(4,838)	64.48
Outstanding at December 31, 2015	3,052,749	$ 58.32	4.36	$ 118,401
Vested and expected to vest	3,038,898	$ 58.27	4.35	$ 118,043
Exercisable at December 31, 2015	2,602,447	$ 56.65	3.70	$ 106,100

The aggregate intrinsic values in the table above represent the total pretax intrinsic value (the difference between our stock price on the last trading day of 2015 and the exercise price, multiplied by the number of in-the-money options/SOSARs) that would have been received by the option holders had all options/SOSARs been exercised on December 31, 2015. These values change based on the fair market value of our common stock. The aggregate intrinsic values of options/SOSARs exercised for the years ended December 31 are as follows:



in thousands	2015	2014	2013
Aggregate intrinsic value of options/
SOSARs exercised	$ 43,620	$ 7,372	$ 4,563

To the extent the tax deductions exceed compensation cost recorded, the tax benefit is reflected as a component of equity in our Consolidated Balance Sheets. The following table presents cash and stock consideration received and tax benefit realized from stock option/SOSAR exercises and compensation cost recorded referable to stock options/SOSARs for the years ended December 31:



in thousands	2015	2014	2013
Stock Options/SOSARs
Cash and stock consideration received
from exercises	$ 72,884	$ 23,199	$ 17,156
Tax benefit from exercises	16,920	2,844	1,770
Compensation cost	2,221	4,650	3,936

CASH-BASED COMPENSATION PLANS

We have incentive plans under which cash awards may be made annually to officers and key employees. Expense provisions referable to these plans amounted to $26,325,000 in 2015, $27,442,000 in 2014 and $19,540,000 in 2013.
