Historically the fund has had a composite benchmark that mirrored its strategic asset allocation.
If its new plans gain unitholder approval, the benchmark will be the IMA global growth sector average from January 1, 2010.
The fund’s asset allocation will remain unchanged but its objectives are also being simplified to reflect the new benchmark.
It will aim to provide capital growth over the medium to long term and to outperform the IMA global growth sector average over rolling three-year periods.
T. Bailey head of sales and marketing Philippa Gee says the change will make it easier for advisers and investors to monitor the fund’s performance against its peers.
She says: “Asset allocation has been a key driver of this fund’s success in the past ten years and the underlying process remains unaltered – we are just making it simpler to measure our success.”
