The duo will utilize the deep value investment style which forms the basis of their other funds at RWC Partners.
The pair left Schroders in May last year where they managed the £1.5bn Schroder income fund and already manage around £1.1bn in an enhanced income fund and an income opportunities fund for their new firm.
The Luxembourg-based unconstrained global portfolio will contain the sizeable overseas weightings the duo are known for from previous income portfolios at Schroders and now at RWC Partners.
The firm seeded the new fund with internal capital. RWC Partners said it had no plan to market the fund to external investors. However, it would be open to external investment.
