Share-Based Compensation

7. Share-Based Compensation

We currently have five types of share-based awards outstanding to our employees and directors: stock options, restricted stock awards, restricted stock units, performance-based 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. Vesting terms for each of these award types generally range from one to four years.

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, 2020, we recognized total share-based compensation costs of $4.3 million and $8.0 million, respectively, including $0.5 million and $0.6 million, respectively, recorded to restructuring and related charges.  For the three and nine months ended September 30, 2019, we recognized total share-based compensation costs of $6.0 million and $15.3 million, respectively, including $0.6 million recorded to restructuring and related charges for the nine months ended September 30, 2019.  We account for forfeitures as they occur.
