The firm says the new five year plan enable investors, aged over 50, to utilise their increased Isa allowance of £10,200 which is effective from October.
The initial investment will be returned in full at maturity as long as the final level of the FTSE 100 is not more than 50 per cent below its initial level.
Should the index breach the 50 per cent protection barrier, capital repayment will be based on the final level of the Index and will be reduced by 1 per cent for each 1 per cent that it has fallen.
Minimum investment is £3,600 and up to a maximum of £2m and IFA commission is 3 per cent.
Securities of the plan are backed by a financial institution with a Standard & Poor’s credit rating of “AA-” at time of writing.
ACI director John Gracey says: “ With saving rates being so low, and likely to remain so for the foreseeable future, ACI is experiencing consistently strong demand for its income products. Not surprisingly, those people who are retired make up the largest percentage of investors. We will continue to issue new versions as each tranche closes and while investors’ interest remains high.”
