On October 1, 2021, we acquired ettain group, one of the largest privately held IT resourcing and services providers in North America. Effective that date, ettain group became part of our Experis business in the Americas segment. The acquisition is intended to accelerate our strategy of diversifying our business mix into higher growth and higher value services. The aggregate cash consideration paid was $930.9. Of the total consideration paid, $925.0 was for the acquired interests and the remaining $5.9 was for excess working capital and cash. The transaction was funded through cash on hand and a $150.0 draw on our revolving credit facility on October 1, 2021. We finalized the purchase accounting during the third quarter of 2022 and recognized post-closing working capital adjustments of $3.4 and income tax adjustments of $3.1 with a corresponding offset to goodwill.

As of December 31, 2021, ettain group contributed revenues from services of $182.7 since the acquisition. Our consolidated unaudited proforma historical revenues from services and net earnings, as if ettain group had been acquired at the beginning of 2020, are estimated as follows:


	Year Ended December 31,
	2021
Revenues from services	$	21,269.1
Net earnings		425.4

The proforma amounts are calculated after applying our accounting policies and adjusting the results of ettain group to reflect the additional amortization that would have been charged assuming a fair value adjustment to intangible assets had been applied from January 1, 2020, with the consequential tax effects.
