Those located outside the United States reported that they spend more on investigations, with 21% saying that their company spends $10 million or more, compared to only 2% of U.S. respondents reporting the same spending level.The top three sources of these expenses were outside counsel (86%), analytics technology (59%) and e-discovery services (53%).
