9. | Stock-Based Compensation
The Company has a stock-based compensation plan known as the National Oilwell Varco, Inc. Long-Term Incentive Plan (the “Plan”). The Plan provides for the granting of stock options, performance-based share awards, restricted stock, phantom shares, stock payments and stock appreciation rights (“SARs”). The number of shares authorized under the Plan is 69.4 million. The Plan is subject to a fungible ratio concept, such that the issuance of stock options and SARs reduces the number of available shares under the Plan on a 1-for-1 basis, and the issuance of other awards reduces the number of available shares under the Plan on a 3-for-1 basis. At June 30, 2018, 9,635,836 shares remain available for future grants under the Plan, all of which are available for grants of stock options, performance-based share awards, restricted stock awards, phantom shares, stock payments and SARs. On February 28, 2018, the Company granted 1,610,599 stock options with a fair value of $10.01 per share and an exercise price of $35.09 per share; 2,391,933 shares of restricted stock and restricted stock units with a fair value of $35.09 per share; performance share awards to senior management employees with potential payouts varying from zero to 449,532 shares; and 14,228 SARs. The stock options vest over a three-year period from the grant date. The restricted stock and restricted stock units vest in three equal annual installments commencing on the first anniversary of the date of grant. The performance share awards can be earned based on performance against established goals over a three-year performance period. The performance share awards are based entirely on a TSR (total shareholder return) goal. Performance against the TSR goal is determined by comparing the performance of the Company’s TSR with the TSR performance of the members of the OSX index for the three-year performance period. On May 11, 2018, the Company granted 35,432 restricted stock awards with a fair value of $40.65 per share. The awards were granted to non-employee members of the board of directors and vest on the first anniversary of the grant date. Total stock-based compensation for all stock-based compensation arrangements under the Plan was $31 million and $58 million for the three and six months ended June 30, 2018, respectively, and $22 million and $52 million for the three and six months ended June 30, 2017, respectively. The total income tax benefit recognized in the Consolidated Statements of Income (Loss) for all stock-based compensation arrangements under the Plan was $4 million and $6 million for the three and six months ended June 30, 2018, respectively, and $5 million and $9 million for the three and six months ended June 30, 2017, respectively.
