The Monte-Carlo simulation model incorporates assumptions as to expected gross profits over the applicable achievement period, including adjustments for the volatility of timing and amount of the associated revenue and costs, as well as discount rates that account for the risk of the underlying arrangement and overall market risks. Any material change to these assumptions may result in a significantly higher or lower fair value of the Deferred Purchase Obligation. The change in value of the Deferred Purchase Obligation during the three months ended March 31, 2023 was driven by the accretion of the obligation to present value.

There were no material items that were measured at fair value on a non-recurring basis at March 31, 2023 and December 31, 2022 other than those disclosed in Note 2.p. to Notes to Consolidated Financial Statements included in our Annual Report.
