STOCK-BASED COMPENSATION

For restricted stock awards and stock options, we had:


	Three Months Ended						Six Months Ended
	June 30,						June 30,
	2019		2018		2019		2018
	(In millions)
Recognized stock compensation expense	$	4.7	$	4.0	$	8.5	$	9.5
Capitalized stock compensation cost for our oil and natural gas properties	0.7		0.6		1.3		1.0
Tax benefit on stock-based compensation	1.2		1.0		2.1		2.3

The remaining unrecognized compensation cost related to unvested awards at June 30, 2019 is approximately $24.8 million, of which $3.4 million is anticipated to be capitalized. The weighted average period over which this cost will be recognized is 0.8 of a year.

Our Second Amended and Restated Unit Corporation Stock and Incentive Compensation Plan effective May 6, 2015 (the amended plan) allows us to grant stock-based and cash-based compensation to our employees (including employees of subsidiaries) and to non-employee directors. 7,230,000 shares of the company's common stock are authorized for issuance to eligible participants under the amended plan with 2,000,000 shares being the maximum number of shares that can be issued as "incentive stock options."

We did not grant any stock options during either of the three or six month periods ending June 30, 2019 or 2018. This table shows the fair value of restricted stock awards granted to employees and non-employee directors during the periods indicated:

The time vested restricted stock awards granted during the first six months of 2019 and 2018 are being recognized over a three-year vesting period. During the first quarter of 2019 and 2018, two performance vested restricted stock awards were granted to certain executive officers. The first cliff vests three years from the grant date based on the company's achievement of certain stock performance measures (TSR) at the end of the term and will range from 0% to 200% of the restricted shares granted as performance shares. The second vests, one-third each year, over a three-year vesting period subject to the company's achievement of cash flow to total assets (CFTA) performance measurement each year and will range from 0% to 200%. Based on a probability assessment of the selected TSR performance criteria at June 30, 2019, the participants are estimated to receive 7% of the 2019 and 63% of the 2018 performance-based shares. The CFTA performance measurement at June 30, 2019 was assessed to vest at target or 100%. The total aggregate stock compensation expense and capitalized cost related to oil and natural gas properties for 2019 awards for the first six months of 2019 was $4.0 million.
