(1)Fair value of cash equivalents (money market funds) and available-for-sale securities (commercial paper and corporate bond securities) was based on quoted vendor prices and broker pricing where all significant inputs were observable.

(2)Fair value of interest rate swap was based on forward-looking, one-month term secured overnight financing rate (“Term SOFR”) spot rates and interest rate curves (Note 7).

(3)Fair value of contingent consideration liabilities was determined based on discounted cash flow analyses that included probability and timing of development and regulatory milestone achievements and a discount rate, which were considered significant unobservable inputs.
