Marathon, which had nearly $50bn of global equities under management, said that the new system is equipped with added functionality and flexibility and has enabled the firm to integrate numerous processes including trade processing, fund accounting and reporting across both the long only and hedge fund portfolios.

Commenting on the addition of the new system, Marathon Asset Management chief operating officer Nick Hughes said the combination of up-to-date and open database technology on a single integrated system gives the company a firm-wide solution and enhances the extent to which its core accounting system interacts with other best of breed systems in use across the firm.

"Not only is the functionality of our previous middle and back office systems now on one integrated platform, but we have considerably more functionality and flexibility than before," Hughes added.

"We have been able to rationalise systems so that we now have a single view of data and a stable accounting platform. Getting the right system was essential – it is and will be the backbone of our business."

Established in 1986, Marathon Asset Management is an independent investment management firm based in the West End of London and manages pension funds, charities and foundations.
