The significant unobservable inputs used in the fair value measurement of the Company’s redeemable noncontrolling interest are the estimated future cash flows based on projected financial data and discount rate of 18.5%. Significant changes in the timing or amounts of the estimated future cash flows would result in a significantly higher or lower fair value measurement. Significant increases or decreases in the discount rate would result in a significantly lower or higher fair value measurement, respectively.
Contingent Consideration
The following table provides a rollforward of the contingent consideration related to the acquisition of Argenta, BioFocus, VivoPath and ChanTest. See Note 2, "Business Acquisitions."

The significant unobservable inputs used in the fair value measurement of the Company's contingent consideration are the probabilities of successful achievement of certain financial targets and a discount rate. Significant increases or decreases in any of the probabilities of success would result in a significantly higher or lower fair value measurement, respectively. Significant increases or decreases in the discount rate would result in a significantly lower or higher fair value measurement, respectively.

Debt Instruments
The book value of the Company's term and revolving loans, which are variable rate loans carried at amortized cost, approximates their fair value based on current market pricing of similar debt. As the fair value is based on significant other observable inputs, including current interest and foreign currency exchange rates, it is deemed to be Level 2.
