Wall Street financial firm UBS lowered its organic revenue growth rate estimates for two of Adland's biggest holding companies—Omnicom and Interpublic Group. The move follows UBS's move earlier
in the week reducing its estimate on U.S. ad spending growth next year to 3.6% from 4%. For Interpublic, UBS said it was reducing its organic growth estimate to 3.6% from 5% for next year and lowering
the holding company's estimated profit (before interest and taxes) to $725 million from $758 million. That equates to a profit margin drop of three-tenths of a percent to 10%, UBS said. For Omnicom,
UBS is reducing its 2012 organic growth estimate to 4.3% versus the prior estimate of 5%. The financial firm is also knocking $40 million of its estimated 2012 pre-tax and-interest profit estimate to
$1.84 billion. UBS cited "global macro concerns" about the economy as the reason for the lowered forecasts.
