Disclaimer: I worked at Aegis for 6 years from 1994 – 2000.
It has not been a good few weeks, months or even years for Dentsu Aegis Network and its constituent parts. Last week Dentsu in Japan admitted that they have been over-charging a large number of their clients (111 is the current number but that could rise), including Toyota for online advertising. This has reportedly been going on for a number of years. Dentsu are admitting guilt since 2012; one of my ex-client contacts suggests it goes back a good 10 years before then.
