Scottish Mortgage Investment Trust is set to enter the FTSE100 on 17 March.
Edinburgh-based asset manager Baillie Gifford runs the trust, which – with £5bn of assets – is the UK’s largest “conventional” investment trust.
It will enter the blue-chip index for the first time since its inception in 1909.
In recognition of its growth, the trust will cut its annual management fee from its current ongoing charge of 0.45 per cent to a tiered fee structure.
From 1 April, the AMC will continue to be 0.3 per cent on the first £4bn of AUM, dropping to 0.25 per cent on higher amounts.
Baillie Gifford partner and co-manager of the trust James Anderson says: “We’re thrilled by the progress over the decade since Scottish Mortgage became a genuinely global trust. The opportunities ahead are compelling but we need to keep improving and cutting costs is a vital and underestimated part of this process.”
