The biggest difference was at WPP, where the chief executive, Sir Martin Sorrell, earned $5m in 2004. Sorrell's package has increased by 126.1% since 2001, during which period profit at WPP grew by 7.8%.
John Wren, the Omnicom chief executive, actually received the largest increase in remuneration, up 137.8% to $5.2m, on profit growth of 43.8%.
Publicis' profits grew 22.2% over the three years, while Maurice Levy, its chairman, received a pay rise of 107.5% to $3.9m.
Only at Havas did profit growth beat the increase in Alain de Pouzilhac's pay, which went up 73.5% to $3.4m, though profit growth was magnified by the fact Havas made a loss in 2001.
Out of the four executives analysed, Wren received the largest portion of his total package as bonus ($4m of his $5.2m package) -- common for US executives. Sorrell's $5m package has a basic salary of $1.5m, while Levy's basic comes in at just less than £1m.
