[1] | The 416,800 shares RSUs were as a result of the reverse acquisition, which were granted to certain directors and employees prior to the TBO Merger, with a verting period ranging from 6 months to 4 years.
[2] | Among the total grants in 2015, 12,312,000 shares, with weighted average grant-date fair value of $9.48, are subject to the Stockholder Approval. Among the 12,312,000 shares, 3,000,000 shares were granted to Frost Gamma, and were vested fully on the grant date, and the remaining shares have a vesting period ranging from 3 to 4 years. For accounting purposes, the grant date was determined to be in 2015, as the Company concluded the Stockholder Approval was perfunctory.
