Subsequent Events	Subsequent EventOn January 18, 2022, we completed the acquisition of AIMDATA, LLC, (“AIMDATA”), an advisory and implementation consulting services firm focused on strategy, technology and business transformation. The results of operations of AIMDATA will be included within our consolidated financial statements from the close date, and will be allocated among our three operating industries, which are our reportable segments, based on the engagements delivered by the business. AIMDATA revenues will be reported in our Digital capability. The acquisition of AIMDATA is not significant to our consolidated financial statements.
