*AER stands for Annual Equivalent Rate and illustrates what the interest rate would be if interest was paid and compounded once each year. This assumes that you invest on the first day of the Offer Period and receive your cashflows as per the contractual terms.
"I invested in a Fortress Bond because the interest rate was attractive and the application process was easy. If the application process was difficult, I wouldn’t have invested."
