Business Acquisition Description Of Contingent Consideration	Earnout payments equal to 15.5% of annual gross revenues are payable if SBX generates annual gross revenues in excess of $10,000,000 and maintains a certain gross profit margin for the remaining earnout period which ends on December 31, 2014. If the Company determines that it is more likely than not that estimated earnout payments for the calendar year ending December 31, 2014 will exceed $1,810,000, the Company would have to increase the contingent earnout liability. Such increase would result in a non-cash charge to the Consolidated Statement of Income.
