Future Value of Liabilities Incurred From Business Acquisitions |  |  |  |  |  | $ 15.3
Valuation Technique on Contingent Consideration |  |  |  |  |  | The fair value of the contingent consideration was measured by applying a probability weighted discounted cash flow model based on significant inputs not observable in the market (Level 3 inputs). Key assumptions include a discount rate of 4.6% and expected future value of payments of $15.3 million. The $15.3 million of expected future payments was calculated using a probability weighted EBITDA assessment with the highest probability associated with rogenSi achieving the targeted EBITDA for each earn-out year
