Stock Options. Approximately $7.2 million in cash proceeds was received from stock option exercises during the nine months ended September 30, 2019.

As of September 30, 2019, we had no unrecognized share-based compensation expense related to unvested stock options.  

Share Grants. Restricted stock awards and restricted stock units generally vest in equal annual installments over a four-year period.   We also have share grants that are performance-based and time-based that vest upon achievement of certain performance criteria over time.             

As of September 30, 2019, total unrecognized share-based compensation expense related to share grants was approximately $44.4 million, before income taxes, and is expected to be recognized over a weighted average period of approximately 2.3 years.
