Fair Value Measurement Inputs and Valuation Techniques [Table Text Block]

The following table provides quantitative information about Level 3 inputs for fair value measurement of our earn-out liability as of December 31, 2017 and September 30, 2018. Significant increases or decreases in these inputs in isolation could result in a significant impact on our fair value measurement:

Adjusted EBITDA Volatility	25.00	%	26.00	%
WACC	8.25	%	8.75	%

Market price of risk	4.99	%	5.99	%
Cost of debt	4.74	%	4.08	%
