At the same time, it confirmed that it would be restating earnings from 2000 to 2004, after mistakes were made in the way it accounted for revenues, leases and acquisitions.
The full-year results for 2004 were originally due in March, but at the time Interpublic said that it was unable to file them and that it had uncovered $145m (拢80m) in overstated revenues, relating to acquisitions made between 1996 and 2001.
The fallout from its failure to file saw chief financial offer Robert Thomson lose his job. In January this year, prior to the revelation, chief executive David Bell stepped down from his role to be replaced by Michael Roth, who has been focusing on getting the company's books in order.
At the same time, this year has seen significant account losses for Interpublic, namely the $3.2bn General Motors media account, which shifted to Publicis Groupe in May, and the Bank of America account, worth $600m, which moved to Omnicom Group earlier this month. Earlier this week, it lost the the $315m account of DIY retailer Lowe's, also to rival Omnicom, as BBDO and OMD scooped the advertising and media.
"I have been clear since assuming my current responsibilities that our top priority is to fix our financial controls and leave accounting issues behind us. The comprehensive review of our financial results and processes that we have undertaken is consistent with this objective," Roth said.
The market did not respond ecstatically to the news, with shares in Interpublic falling by 1.4% during morning trading on the New York Stock Exchange to trade at $11.17.
The account losses and financial troubles have led industry watchers to speculate about whether there is an independent future for Interpublic.
