Incapital’s Capital Accumulator Auto-Call - Dual-Index Series Plans 9 and 10 are aimed at delivering growth potential without the requirement of underlying stock market growth. Issue 9 aims to deliver growth potential of 12.25 per cent annualised over a six-year term, while Issue 10 aims to deliver 13.25 per cent growth.

An early closure “auto-call” feature is applicable to both the products from their second anniversary, meaning that there will be a 24.5 or 26.5 per cent return – along with the repayment of the initial capital – if the FTSE100 and S&P500 have not fallen below their initial levels. Capital is however at risk if the indices have fallen more than 50 per cent from their start levels when the plans mature.

Issue 9 of the plan is backed by Rabobank, while Issue 10 is backed by Santander UK. This choice of counterparties allows for better diversification and satisfies regulatory requirements, Incapital said in a statement.

The products will close to new business on 16 August, with their strike date being 20 July. The minimum investment per plan is £10,000 (around $15,000) for direct investment, £10,200 for new ISAs and £5,000 for ISA transfers. Standard commission for intermediaries is 2.75 per cent.
