Stock compensation

The Company uses various equity-based compensation programs to provide long-term performance incentives for its global workforce. Currently, these incentives consist principally of stock options, restricted stock units, and to a lesser extent, executive performance shares and restricted stock grants. The Company also sponsors a discounted stock purchase plan in the United States and matching-grant programs in several international locations. Additionally, the Company awards restricted stock to its outside directors. The interim information below should be read in conjunction with the disclosures included within the stock compensation footnote of the Company’s 2015 Annual Report on Form 10-K.

The Company classifies pre-tax stock compensation expense in COGS and SGA expense principally within its corporate operations. For the periods presented, compensation expense for all types of equity-based programs and the related income tax benefit recognized was as follows:



	Quarter ended				Year-to-date period ended
(millions)	October 1, 2016		October 3, 2015		October 1, 2016		October 3, 2015
Pre-tax compensation expense	$	16	$	12	$	49	$	37
Related income tax benefit	$	6	$	4	$	18	$	13

As of October 1, 2016, total stock-based compensation cost related to non-vested awards not yet recognized was $99 million and the weighted-average period over which this amount is expected to be recognized was 2 years.

Stock options

During the year-to-date periods ended October 1, 2016 and October 3, 2015, the Company granted non-qualified stock options to eligible employees as presented in the following activity tables. Terms of these grants and the Company’s methods for determining grant-date fair value of the awards were consistent with that described within the stock compensation footnote in the Company’s 2015 Annual Report on Form 10-K.

Year-to-date period ended October 1, 2016:

The weighted-average grant date fair value of options granted was $9.44 per share and $7.20 per share for the year-to-date periods ended October 1, 2016 and October 3, 2015, respectively. The fair value was estimated using the following assumptions:



	Weighted- average expected volatility		Weighted- average expected term (years)	Weighted- average risk-free interest rate		Dividend yield
Grants within the quarter ended October 1, 2016:	17	%	6.9	1.60	%	2.60	%
Grants within the quarter ended October 3, 2015:	16	%	6.9	1.98	%	3.00	%

The total intrinsic value of options exercised was $140 million and $50 million for the year-to-date periods ended October 1, 2016 and October 3, 2015, respectively.

Performance shares

In the first quarter of 2016, the Company granted performance shares to a limited number of senior executive-level employees, which entitle these employees to receive a specified number of shares of the Company’s common stock upon vesting. The number of shares earned could range between 0 and 200% of the target amount depending upon performance achieved over the three year vesting period. The performance conditions of the award include three-year currency-neutral comparable operating profit growth and total shareholder return (TSR) of the Company’s common stock relative to a select group of peer companies.

A Monte Carlo valuation model was used to determine the fair value of the awards. The TSR performance metric is a market condition. Therefore, compensation cost of the TSR condition is fixed at the measurement date and is not revised based on actual performance. The TSR metric was valued as a multiplier of possible levels of comparable operating profit growth achievement. Compensation cost related to comparable operating profit growth performance is revised for changes in the expected outcome. The 2016 target grant currently corresponds to approximately 176,000 shares, with a grant-date fair value of $80 per share.

Based on the market price of the Company’s common stock at October 1, 2016, the maximum future value that could be awarded to employees on the vesting date for all outstanding performance share awards was as follows:



(millions)	October 1, 2016
2014 Award	$	30
2015 Award	$	24
2016 Award	$	27

The 2013 performance share award, payable in stock, was settled at 35% of target in February 2016 for a total dollar equivalent of $3 million.
