The fund fact sheet is produced and held by FE Fund Info. If a fact sheet isn’t available it’s likely because of the subscription level that the fund manager has with FE. Certain subscription levels come with a fact sheet, others do not.
If a fact sheet isn’t available, the fund manager should contact FE directly to request it.
More information on FE and the allocations of the funds can be seen on their website: https://www.fefundinfo.com/en-gb/ or https://www.trustnet.com/
