Description for additional consideration   As part of this acquisition, the Company agreed to (1) an additional payment equal to 2X the EBITDA increase for the twelve months beginning on January 1, 2015 and concluding March 31, 2015 and (2) an additional payment equal to 2.5X the EBITDA increase over the first year EBITDA calculated as of the March 31, 2015 for the period beginning on April 1, 2015 and concluding on March 31, 2016. The Company determined the fair value of the contingent consideration to be $1,873 at the date of acquisition.                         As additional consideration, the Company agreed to provide the VaultLogix sellers certain price protection. If the closing price per share of the Company's common stock 180 days after the closing was less than 90% of $16.50, as adjusted for any stock splits, dividends, recapitalizations, or similar transactions, then the Company was required to issue additional shares of common stock. Additionally, the adjusted closing price for purposes of the calculation could not be less than $12.50 per share. As such, the price protection of $870 was recorded as a liability on the Company's balance sheet.
