STOCK-BASED COMPENSATION

Our 2014 Long Term Stock Incentive Plan (the “2014 Plan”) provides for the issuance of stock-based incentives in various forms to our employees and non-employee Directors. At June 30, 2016, outstanding stock-based incentives were in the form of long-term stock awards, stock options, phantom stock awards and stock appreciation rights. Pre-tax compensation expense and the related income tax benefit for these stock-based incentives were as follows, in millions:

Total	$	6		$	13	$	15	$	23
Income tax benefit (37 percent tax rate)	$	3		$	5	$	6	$	9

Long-Term Stock Awards. Long-term stock awards are granted to our key employees and non-employee Directors and do not cause net share dilution inasmuch as we continue the practice of repurchasing and retiring an equal number of shares in the open market. We granted 1,050,380 shares of long-term stock awards in the six-month period ended June 30, 2016.

(A) In connection with the spin off of TopBuild, TopBuild employees forfeited their outstanding Masco equity awards.

(B) Subsequent to the separation of TopBuild, we modified our outstanding equity awards to employees and non-employee Directors such that all individuals received an equivalent fair value both before and after the separation. The modification to the outstanding stock awards was made pursuant to existing anti-dilution provisions in our 2014 Plan and 2005 Long Term Incentive Plan.

At June 30, 2016 and 2015, there was $55 million and $52 million, respectively, of total unrecognized compensation expense related to unvested stock awards; such awards had a weighted average remaining vesting period of three years at both June 30, 2016 and 2015.

The total market value (at the vesting date) of stock award shares which vested during the six-month periods ended June 30, 2016 and 2015 was $38 million and $49 million, respectively.

Stock Options. Stock options are granted to our key employees. The exercise price equals the market price of our common stock at the grant date. These options generally become exercisable (vest ratably) over five years beginning on the first anniversary from the date of grant and expire no later than 10 years after the grant date.

We granted 474,500 of stock option shares in the six-month period ended June 30, 2016 with a grant date exercise price approximating $26 per share. In the six-month period ended June 30, 2016, no stock option shares were forfeited (including options that expired unexercised).

Subsequent to the separation of TopBuild, we modified our outstanding equity awards to employees and non-employee Directors such that all individuals received an equivalent fair value both before and after the separation. The modification to the outstanding options was made pursuant to existing anti-dilution provisions in our 2014 Plan and 2005 Long Term Incentive Plan. The modification contributed to the lower exercise price.


(B)	Aggregate intrinsic value is calculated using our stock price at each respective date, less the exercise price (grant date price), multiplied by the number of shares.


(C)	In connection with the spin off of TopBuild, TopBuild employees forfeited their outstanding Masco equity awards.
