Our marketable securities are classified as Level 2 within the fair value hierarchy, as we measure their fair value using market prices for similar instruments and inputs such as actual trade data, benchmark yields, broker/dealer quotes and other similar data obtained from quoted market prices or independent pricing vendors.

Assets and Liabilities That Are Measured at Fair Value on a Nonrecurring Basis

Fair value of the revenue-based business acquisition liabilities was determined using a discounted cash flow model and an option pricing model. The significant inputs of such models are not observable in the market, such as certain financial metric growth rates, volatility and discount rates, market price risk adjustment, projections associated with the applicable milestone, the interest rate, and the related probabilities and payment structure in the contingent consideration arrangement.

The following are the significant unobservable inputs used in the two valuation techniques:

* The weighted average rates were calculated based on the relative fair value of each business acquisition liability.
