As of February 24, 2018, we have stock options, restricted stock awards, restricted stock units and performance share units (collectively referred to as “stock-based awards”) outstanding under the 2012 Stock Plan and 2007 Stock Plan. Our 2012 Stock Plan, which was amended and restated in fiscal 2015 and further amended in fiscal 2017 (as amended, the “2012 Stock Plan”), is the only plan under which stock-based awards may be granted to employees. The 2012 Stock Plan provides that the Board of Directors or the Leadership Development and Compensation Committee of the Board (the “Compensation Committee”) may determine at the time of grant whether each stock-based award granted will be a non-qualified or incentive stock-based award under the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”). The terms of each stock-based award will be determined by the Board of Directors or the Compensation Committee. Generally, stock-based awards granted from fiscal 2006 to fiscal 2012 generally have a term of seven years, and starting in fiscal 2013 stock-based awards granted generally have a term of ten years.

At the discretion of the Board of Directors or the Compensation Committee, we have granted stock options to purchase common stock at an exercise price not less than 100 percent of the fair market value of our common stock on the date of grant, restricted stock awards, restricted stock units and performance share units (“PSUs”) to executive officers and other key salaried employees. Stock options have also been granted to our non-employee directors. All stock options, restricted stock awards, restricted stock units and PSUs issued in fiscal 2018, and 2017 vest either pro rata over three years or cliff vest after three years. The restrictions on the restricted stock awards and restricted stock units generally lapse between one and five years from the date of grant. The performance metrics of PSUs are determined at the discretion of the Board of Directors or Compensation Committee.

As of February 24, 2018, there were 4 shares available for future issuance of stock-based awards under the 2012 Stock Plan. Common stock has been delivered out of treasury stock or newly issued shares upon the exercise or vesting of stock-based awards. The provisions of future stock-based awards may change at the discretion of the Board of Directors or the Compensation Committee.

For our annual grant made in the first quarter of fiscal 2018, 2017 and 2016, we granted 36 thousand, 137 thousand and 552 thousand, respectively, of non-qualified stock options to certain employees under the 2012 Stock Plan with a weighted average grant date fair value of $13.92, $18.68 and $25.69 per share, respectively. These stock options vest over a period of three years, and were awarded as part of a broad-based employee incentive initiative designed to retain and motivate employees across Supervalu.

We estimated the fair value of each option on the date of grant using the Black Scholes option pricing mode, based upon the following assumptions:



	2018		2017		2016
Dividend yield	—	%	—	%	—	%
Volatility rate	53.7	%	54.2	%	49.0 – 56.5%
Risk-free interest rate	1.8	%	1.3	%	1.2 – 1.4%
Expected option life	5.0 years		5.0 years		5.0 years

Restricted Stock

Restricted stock awards and restricted stock unit activity consisted of the following:



	Restricted Stock Units (In thousands)		Restricted Stock Awards (In thousands)		Weighted Average Grant Date Fair Value⁽¹⁾

(1) Weighted average grant date fair value is only used for restricted stock awards.

In fiscal 2018 and 2017, we granted restricted stock units that vest over a three-year period from the date of the grant. In fiscal 2016, we granted restricted stock awards that vest over a three-year period from the date of grant. The fair value of restricted stock awards and restricted stock units is based on the closing price of our common stock on the date of grant.

Performance Share Units

In fiscal 2018 and 2017, we granted 178 thousand and 201 thousand PSUs, respectively, to certain employees under the 2012 Stock Plan. The PSUs granted in fiscal 2018 have a fiscal 2018-2020 performance period and the PSUs granted in fiscal 2017 have a fiscal 2017-2019 performance period, and both settle in shares of our common stock. We used the Monte Carlo method to estimate the fair value of the PSUs at grant date based upon the following assumptions:



	2018		2017
Dividend yield	—	%	—	%
Volatility rate	44.3	%	41.3	%
Risk-free interest rate	1.41	%	0.9	%
Expected PSU life	2.8 years		2.8 years

Performance share unit activity consisted of the following:



	Performance Share Units (In thousands)		Weighted Average Grant Date Fair Value
Outstanding, February 27, 2016	—		$	—
Granted	201		45.17
Lapsed	—		—
Canceled and forfeited	(29	)	45.17
Outstanding, February 25, 2017	172		$	45.17

Outstanding, February 24, 2018	270		$	40.75

Stock-Based Compensation Expense

The components of pre-tax stock-based compensation expense are included primarily in Selling and administrative expenses in the Consolidated Statements of Operations. The expense recognized and related tax benefits were as follows:



	2018			2017			2016
Stock-based compensation	$	19		$	17		$	21
Income tax benefits	(7		)	(7		)	(8		)
Stock-based compensation, net of tax	$	12		$	10		$	13

Unrecognized Stock-Based Compensation Expense

As of February 24, 2018, there was $23 of unrecognized compensation expense related to unvested stock-based awards granted under our stock plans. The expense is expected to be recognized over a weighted average remaining vesting period of approximately 2 years.
