Your capital is at risk and the value of your investment may go down as well as up, and you may not get back the amount originally invested. Income is variable and not guaranteed. Currency fluctuations may also affect the value of your investment.

*Interest rate quoted is Annual Equivalent Rate (AER) and illustrates what the interest rate would be if interest was paid and compounded once each year. Tax free is the contractual rate of interest payable where the interest is exempt from income tax. The favourable tax treatment for ISAs and Junior ISAs could change.

**Check with your current provider to see if there are any charges and/or conditions which may affect your ISA transfer.
