[1] | All share data for all periods have been retroactively restated to reflect IDI's 1-for-5 reverse stock split, which was effective on March 19, 2015.
[2] | As IDI Holdings, LLC, the accounting acquirer of the merger consummated effective as of March 21, 2015, was incorporated on September 22, 2014, the comparative figures for the corresponding period in 2014 were from the date of inception through December 31, 2014.
[3] | 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.
