According to a report in the Wall Street Journal, Interpublic, headed by chairman and chief executive David Bell, has taken the decision partly because of the difficulty of accurately stating the number and because it is not convinced it adds much value for investors.
Last week, Interpublic, which owns McCann Erickson and Lowe, reported first-quarter losses of $16.9m (拢9.5m) compared with $8.6m last year.
In its first-quarter results, which it released last week, Interpublic named some of its big account wins for the period but did not state the total billings. It also included accounts that had been up for review but were retained by Interpublic agencies.
The other big holding companies -- WPP Group, Omnicom Group and Publicis Groupe -- still report their new wins, leading to some speculation that if Interpublic were performing better then it would continue to do the same.
The net new-business figure is usually stated as the total billings for the accounts that have been won, even though the majority of that figure is usually for the media spend and only a small percentage goes to the advertising agency as revenue.
There are also problems where the client hands the agency brand-extension work for an existing account and whether this counts as new business or not.
However, some see the figures as particularly useful with one analyst with William Blair & Co in the US saying "it is an extremely valuable metric" to help decipher a company's performance.
