Equity Based Employee Benefit Plans

Staples offers its associates share ownership through certain equity-based employee compensation and benefit plans. In connection with these plans, Staples recognized $63 million, $64 million and $81 million of compensation expense for 2015, 2014 and 2013, respectively. The total income tax benefit related to stock-based compensation was $20 million, $18 million, $23 million for 2015, 2014 and 2013, respectively. As of January 30, 2016, Staples had $71 million of unamortized stock compensation expense associated with its equity-based plans, which will be expensed over a weighted-average period of 1.5 years.

Stock Award Plan

Under the 2014 Stock Incentive Plan, the Company may grant restricted stock and restricted stock units (collectively, “Restricted Shares”) and non-qualified stock options to associates. Prior to June 2014, Restricted Shares and non-qualified stock options were granted under the Company's Amended and Restated 2004 Stock Incentive Plan. Shares issued pursuant to restricted stock awards are restricted in that they are not transferable until they vest. Shares underlying awards of restricted stock units are not issued until the units vest. Non-qualified stock options cannot be exercised until they vest. For stock awards with service conditions only, vesting occurs over different periods, depending on the terms of the individual award, but expenses relating to these awards are recognized on a straight line basis over the applicable vesting period. For awards that include performance conditions, the Company recognizes compensation expense during the performance period to the extent achievement of the performance condition is deemed probable relative to targeted performance. A change in the Company's estimate of the probable outcome of a performance condition is accounted for in the period of the change by recording a cumulative catch-up adjustment.

Performance Shares

In April 2013, March 2014 and March 2015, the Company entered into long-term performance share agreements with certain executives. Vesting is 50% based on satisfaction of certain sales growth metrics and 50% based on achievement of certain return on net assets percentage targets. Payout under these arrangements may range from 25% to 200% of target for each metric, depending on actual performance. Each award covers a three year period. Vesting is based on performance in each fiscal year, with metrics established at the beginning of each year. Any award earned based on performance may be increased or decreased by 25% if the Company's cumulative total shareholder return ("TSR") over the three year performance period is in the top or bottom one-third of the S&P 500 TSR, respectively. Shares earned, if any, will be issued on a fully-vested basis at the conclusion of the three-year performance period only if the grantee is still actively employed by or serving as a consultant to the Company at that time, with certain exceptions for retirement, death, disability, and termination without cause.

For each performance period completed, the table below shows the target number of shares, the aggregate grant-date fair value, and the percentage of target shares earned based on the extent to which the performance targets were achieved, subject to adjustment based on TSR at the end of the three year performance period.



Performance period	Award date	Target number of shares (millions)	Grant date fair value (millions)	% of target shares earned
2015	March 2015	0.5	$7	78.4%
	March 2014	0.5	$9
	April 2013	0.5	$8
2014	March 2014	0.6	$7	87.3%
2014	April 2013	0.5	$6	87.3%
2013	April 2013	0.5	$7	49.7%
