Fair Value Measurements
To limit exposure to volatility in the LIBOR interest rate, the Company has entered into interest rate swap agreements, which effectively convert the variable interest rate on the outstanding revolving credit facility discussed in Note 10 to a fixed rate. The fair values of the interest rate swap agreements were determined by reference to a third-party valuation, which is considered a Level 2 input within the fair value hierarchy of valuation techniques. In conjunction with the paydown of $25,000 on the revolving credit facility in March 2022, a $25,000 interest rate swap agreement was terminated, resulting in a gain of $935, which is recorded in other expense, net in our Consolidated Statement of Operations for the year ended September 30, 2022.
As indicated in Note 4, we acquired EUPROTEIN Inc. of North Brunswick, New Jersey (“EUPROTEIN”) on April 30, 2022 and BreathTek on July 31, 2021. The fair values of inventories acquired were valued using Level 2 inputs, which included data points that were observable, such as established values of comparable assets and historical sales information (market approach). Identifiable intangible assets, if applicable and specifically the acquired customer relationships, were valued using Level 3 inputs, which are unobservable by nature, and included internal estimates of future cash flows and attrition rates (income approach). Significant increases (decreases) in any of those unobservable inputs, as of the date of the acquisition, in isolation would result in a significantly lower (higher) fair value measurement.
 
In connection with the acquisition of the business of GenePOC, Inc. (“GenePOC”) in fiscal 2019 and subsequent amendments to modify certain terms of the agreement related to contingent consideration achievement levels and milestone dates, the Company was required to make contingent consideration payments of up to $64,000 (originally $70,000 at the acquisition date), comprised of up to $14,000 for achievement of product development milestones (originally $20,000 at the acquisition date) and up to $50,000 for achievement of certain financial targets. The fair value for the contingent consideration recognized upon the acquisition as part of the purchase price allocation was $27,202. Giving effect to subsequent agreements to modify certain terms of the agreement related to contingent consideration achievement levels and milestone dates, the fair value of the product development milestone payments were estimated by discounting the probability-weighted contingent payments to present value and presented on the Consolidated Balance Sheets based on the Company’s anticipated date of payment at each reporting period. Assumptions used in the calculations included probability of success, duration of the earn-out and discount rate, with such calculations being updated for the effect of the previously noted amendments to the contingent consideration achievement levels and milestone dates. The fair value of the financial performance target payments was determined using a Monte Carlo simulation-based model. Assumptions used in these calculations included expected net revenues, probability of certain developments, expected expenses and discount rate. In August 2021, the Company paid $20,000 to settle the contingent consideration obligation, resulting in a $909 net gain for the year ended September 30, 2021.

Supplemental Cash Flow Information (Non-Cash Acquisition Consideration)
In arriving at the $20,000 settlement payment in fiscal 2021, the acquisition consideration obligation related to acquisition of the GenePOC business decreased $909 during the year ended September 30, 2021, due in large part to amendment of certain terms of the original contingent consideration achievement levels and milestone dates, as well as the settlement in August 2021.
