Tax benefit on stock-based compensation	1.0		1.2		2.3		2.2

The remaining unrecognized compensation cost related to unvested awards at June 30, 2018 is approximately $23.7 million, of which $3.0 million is anticipated to be capitalized. The weighted average period over which this cost will be recognized is 1.0 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 granted no SARs or stock options during either of the three or six month periods ending June 30, 2018 or 2017. 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 2018 and 2017 are being recognized over a three-year vesting period. During the first quarter of 2018 and 2017, two performance vested restricted stock awards were granted to certain executive officers. The first will cliff vest 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 will vest, 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, 2018, the participants are estimated to receive 25% of the 2018, 91% of the 2017, and 167% of the 2016 performance-based shares. The CFTA performance measurement at June 30, 2018 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 2018 awards for the first six months of 2018 was $4.3 million.
