4.	Share-Based Compensation

We currently have three types of share-based awards outstanding to our employees and directors: stock options, restricted stock units, and market stock units. We believe that our share-based awards align the interests of our employees and directors with those of our stockholders.

We recognize share-based compensation expense for the market stock units if the requisite service period is rendered, even if the market condition is never satisfied. For the three and nine months ended September 30, 2017, we recognized share-based compensation costs of $1.7 million and $5.0 million, respectively. For the three and nine months ended September 30, 2016, we recognized share-based compensation costs of $10.0 million and $15.4 million, respectively, of which $8.4 million and $10.2 million, respectively, are in discontinued operations and include the acceleration of vesting of all unvested stock options, market stock units and restricted stock units held by two former senior executives as of Closing who had accepted employment with Sharecare. Beginning in January 2017 with the adoption of ASU 2016-09, we account for forfeitures as they occur.
