The preliminary fair values of the net assets recognized in the Company’s consolidated financial statements were based on management’s best estimates of the acquired identifiable assets and liabilities at the acquisition dates. Management finalized the fair value assessments of assets and liabilities purchased from Engenium, Driven by Values, Paleo, Cox McLean, and Cardno Limited. For Barton Willmore and L2P, management is reviewing vendor's closing financial statements, purchase adjustments, and other outstanding information.
