The asset managers join another eight that have already agreed to be part of the new investment range, which is expected to launch halfway through next year.
Aberdeen, Blackrock, BNY Mellon, Fidelity, Henderson, JP Morgan, Schroders and Threadneedle are the other groups participating in the range.
Paul Feeney, chief executive of Old Mutual Wealth, which owns Skandia, said: “We are pleased to confirm the full manager line-up for this exciting new fund range which will launch next year.
“Working in close partnerships with such fine quality fund managers, we are looking forward to delivering this unique and highly competitive proposition.”
The range will be available exclusively through Skandia on its Skandia Investment Solutions platform. It will comprise around 50 funds managed as sub-advised retail mandates and will cover all major asset classes.
M&G, which has partnered with Skandia for a number of years, is unable to provide sub-advised retail mandate services. However, it has been named a strategic partner on the range and is looking at ways it can be involved in the future.
