Valuation Model and Assumptions

The Company uses the Black-Scholes option-pricing model to estimate the fair value of share-based awards. The Black-Scholes option-pricing model incorporates various and subjective assumptions, including expected term and expected volatility.

The following table shows the Company’s assumptions used to compute share-based compensation expense for awards granted during the thirteen weeks ended May 5, 2018 and April 29, 2017:



		Stock Option Plans						Stock Purchase Plan
		May 5,			April 29,			May 5,			April 29,

The total fair value of options vested as of May 5, 2018 and April 29, 2017 was $8 million and $7 million, respectively. The cash received from option exercises and the related tax benefit for the thirteen weeks ended May 5, 2018 was not significant.

The total intrinsic value of options exercised (the difference between the market price of the Company’s common stock on the exercise date and the price paid by the optionee to exercise the option) is presented below:

Restricted Stock and Restricted Stock Units

Restricted shares of the Company’s common stock and restricted stock units (“RSU”) may be awarded to certain officers and key employees of the Company. Additionally, RSU awards are made to employees in connection with the Company’s long-term incentive program, and to nonemployee directors. Each RSU represents the right to receive one share of the Company’s common stock provided that the performance and vesting conditions are satisfied. There were 874,458 and 669,542 RSU awards outstanding as of May 5, 2018 and April 29, 2017, respectively.

Generally, awards fully vest after the passage of time, typically three years. However, RSU awards made in connection with the Company’s performance-based long-term incentive program are earned after the attainment of certain performance metrics and vest after the passage of time. Restricted stock is considered outstanding at the time of grant and the holders have voting rights. Dividends are paid to holders of restricted stock that vest with the passage of time. With regard to performance-based restricted stock, dividends will be accumulated and paid after the performance criteria are met. No dividends are paid or accumulated on RSU awards. Compensation expense is recognized using the market value at the date of grant and is amortized over the vesting period, provided the recipient continues to be employed by the Company.

Restricted stock and RSU activity for the thirteen weeks ended May 5, 2018 is summarized as follows:


			Weighted-
			Average	Weighted-
		Number	Remaining	Average
		of	Contractual	Grant Date

Nonvested at May 5, 2018		883	2.5	$	50.22
Aggregate value ($ in millions)	$	44


(1)	Approximately 0.4 million performance-based RSUs were granted during the first quarter of 2018 and are included as granted in the table above. The number of performance-based RSUs that are ultimately earned may vary from 0% to 200% of target depending on the achievement relative to the Company’s predefined financial performance targets.
(2)	Adjustments were made to performance-based RSUs previously granted and are included as cancelled in the table above. These adjustments reflect changes in estimates based upon the Company’s current performance against predefined financial targets.

The total value of awards for which restrictions lapsed during the thirteen weeks ended May 5, 2018 and April 29, 2017 was $5 million and $13 million, respectively. As of May 5, 2018, there was $33 million of total unrecognized compensation cost related to nonvested restricted awards.
