9. Stock-based Compensation and Outstanding Awards

In connection with the Separation, the Company and NOV entered into the Employee Matters Agreement which governs the Company and NOV’s compensation and employee benefit obligations with respect to current and former employees of each company, and generally allocates liabilities and responsibilities relating to employee compensation and benefit plans and programs. Such agreement provided the adjustment mechanisms applied as a result of the Spin-Off to convert outstanding NOV equity awards held by Company employees to Company awards.

The Company has a stock-based compensation plan known as the NOW Inc. Long-Term Incentive Plan (the “Plan”). Under the Plan, the Company’s employees are eligible to be granted stock options, restricted stock awards (“RSAs”), restricted stock units (“RSUs”), and performance stock awards (“PSAs”).

For the six months ended June 30, 2017, the Company granted 915,037 stock options with a weighted average fair value of $7.07 per share and 194,183 shares of RSAs and RSUs with a weighted average fair value of $19.92 per share. In addition, the Company granted PSAs to senior management employees with potential payouts varying from zero to 169,346 shares. These options vest over a three-year period from the grant date on a straight-line basis over the requisite service period for each separately vesting portion of the award as if the award was, in-substance, multiple awards. The RSAs and RSUs vest on the first and third anniversary of the date of grant. The PSAs can be earned based on performance against established metrics over a three-year performance period.
