Americas' chief Phil Moyles and COO Mark Feuer are the latest departures
Marsh, the international broker, has suffered the loss of two senior executives.
Marsh Americas' chief executive Phil Moyles has resigned and Mark Feuer, chief operating officer, has left the company.
This follows the recent axing of Michael Cherkasky, chief executive of Marsh's parent company MMC on 21 December.
Marsh recently hired Daniel Glaser from AIG to replace Brian Storms as its global chief executive. Storms lost his post following consecutive quarters of poor results last year.
According to Reuters, billionaire Nelson Peltz is understood to have shown interest in taking a stake in parent company MMC as a result.
Reuters said that the move formed part of a management shake-up by Glaser.
Marsh said it expects to release further details in the next few hours, and that statements will be made to the stock exchange shortly.
Over past week, MMC shares have risen by over 3.5%, and are currently trading at $27.12.
