NOTE 11: INCENTIVE PLANS

SHARE-BASED COMPENSATION PLANS

Our 2016 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 8,000,000.

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 $12,074,000 in 2016, $13,159,000 in 2015 and $16,863,000 in 2014.

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, 2016:



	Target	Weighted-average
	Number	Grant Date
	of Shares	Fair Value
Performance Shares
Nonvested at January 1, 2016	806,339	$ 63.13
Granted	164,498	87.73
Vested	(289,424)	53.65
Canceled/forfeited	(14,317)	68.49
Nonvested at December 31, 2016	667,096	$ 73.20

During 2015 and 2014, the weighted-average grant date fair value of performance shares granted was $74.85 and $63.42, 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	2016	2015	2014
Aggregate value of distributed
performance shares	$ 60,443	$ 26,258	$ 0

RESTRICTED SHARES — Each restricted share unit is equal to and paid in one share of our common stock, but carries no voting or dividend rights. Awards vest on the fourth anniversary of the grant date. 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 restricted share awards amounted to $3,004,000 in 2016, $982,000 in 2015 and $704,000 in 2014.

The fair value of restricted shares is estimated as of the date of grant based on the stock price adjusted for dividends foregone. The following table summarizes the activity for nonvested restricted share units during the year ended December 31, 2016:



		Weighted-average
	Number	Grant Date
	of Shares	Fair Value
Restricted Stock Units
Nonvested at January 1, 2016	74,000	$ 58.23
Granted	63,350	87.77
Vested	0	0.00
Canceled/forfeited	(1,920)	87.77
Nonvested at December 31, 2016	135,430	$ 71.63

The weighted-average grant date fair value of restricted shares granted in 2015 was $74.85. No restricted shares were granted in 2014.

There were no distributions of restricted shares during 2016, 2015 and 2014.

STOCK ONLY STOCK APPRECIATION RIGHTS (SOSARs) — SOSARs granted have an exercise price equal to the market value of our underlying common stock on the date of grant. The 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 SOSARs is estimated as of the date of grant using the Black-Scholes option pricing model. Compensation cost for 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:



	2016	2015	2014
SOSARs
Fair value	$ 29.20	$ 25.17	$ 21.94
Risk-free interest rate	1.66%	1.85%	2.40%
Dividend yield	1.39%	1.70%	1.64%
Volatility	30.42%	33.00%	33.00%
Expected term	9.00 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 SOSAR activity as of December 31, 2016 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)
SOSARs/Stock Options 1
Outstanding at January 1, 2016	3,052,749	$ 58.32
Granted	97,700	92.02
Exercised	(753,251)	83.29
Forfeited or expired	(4,767)	78.22
Outstanding at December 31, 2016	2,392,431	$ 51.80	4.30	$ 178,558
Vested and expected to vest	2,379,036	$ 51.70	4.28	$ 177,794
Exercisable at December 31, 2016	2,005,030	$ 47.30	3.62	$ 158,651


1	There were no stock options outstanding at December 31, 2016.

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 2016 and the exercise price, multiplied by the number of in-the-money SOSARs) that would have been received by the option holders had all SOSARs been exercised on December 31, 2016. These values change based on the fair market value of our common stock. The aggregate intrinsic values of SOSARs/ stock options exercised for the years ended December 31 are as follows:



in thousands	2016	2015	2014
Aggregate intrinsic value of SOSARs/
stock options exercised	$ 27,705	$ 43,620	$ 7,372

The following table presents cash and stock consideration received and tax benefit realized from stock option/SOSAR exercises and compensation cost recorded referable to SOSARs/stock options for the years ended December 31:



in thousands	2016	2015	2014
SOSARs/Stock Options
Cash and stock consideration received
from exercises	$ 0	$ 72,884	$ 23,199
Tax benefit from exercises	10,767	16,920	2,844
Compensation cost	2,744	2,221	4,650

DEFERRED STOCK UNITS — In addition to the share-based compensation plans for employees discussed above, we issue a limited number of deferred stock units to our nonemployee directors annually. These deferred stock units vest over three years (except for the 2016 grant which vested upon issuance) and accumulate dividends over the vesting period. Expense provisions referable to nonemployee director deferred stock units amounted to $2,848,000 in 2016, $1,886,000 in 2015 and $1,668,000 in 2014.

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 $32,169,000 in 2016, $26,325,000 in 2015 and $27,442,000 in 2014.
