Inflows for the period fell to £218m compared to £649m in 2010 and the firm said it continued to attract new money across all asset classes.
RLAM said a significant portion of its retail and institutional client monies were invested through its Oeics.
It said that over the 12 months to end of September two thirds of these funds had achieved a first or second quartile ranking and outperformed their respective IMA sector averages.
Over three years to the end of September an even higher number of funds were in the top two quartiles, with three quarters achieving the accolade.
Chief executive of Royal London, Phil Loney, said: "Inevitably, asset management companies have been affected by poor investment markets and a near term aversion to risk assets, but RLAM still achieved a good level of net inflows of funds."
