At March 31, 2019, there was $99,802 of unrecognized stock-based compensation expense related to unvested restricted stock units and awards, which the Company expects to recognize over a weighted-average period of 2.4 years.

In February 2019, the Company granted approximately 69,000 performance-based restricted stock unit awards to certain employees. These performance-based restricted unit awards vest upon the achievement of certain pre-established business and financial metrics as well as service condition. The business and financial metrics governing the vesting of these performance-based restricted stock unit awards provide thresholds which dictate the number of shares to vest upon each evaluation date, which range from 50% to 150%. If these metrics are achieved, as defined in the individual grant terms, these shares would cliff vest three years from the grant date.
