There is a risk that the issuers of fixed income investments (e.g. bonds) may not be able to meet interest payments nor repay the money they have borrowed. The worse the credit quality of the issuer, the greater the risk of default and therefore investment loss.
Investments may be primarily concentrated in specific countries, geographical regions and/or industry sectors. This may result in wider fluctuations in the value of the portfolio compared to more broadly invested portfolios.
