[2] For the contingent consideration related to the 2021 acquisition of certain assets and liabilities of DataFuzion HCM, Inc. ("DataFuzion"), we utilized a Monte Carlo simulation model to estimate the fair value of the contingent liability as of the reporting dates. As of June 30, 2024 and December 31, 2023, $8.6 million of the contingent consideration is included within other accrued expenses in our condensed consolidated balance sheets, and $6.3 million of the contingent consideration is included within other liabilities in our condensed consolidated balance sheets.
