In short, your funds and investment remain safe.
The addy platform is beneficial for issuers as it allows them to easily complete distributions to thousands of different investors.
If addy no longer existed at the time of an Owners’ Day, then the issuer would still be contractually obligated to ensure you receive your funds. In that situation, they would write individual cheques to the members who have invested in the properties. The additional fees and cumbersome nature of this process means that your returns may be slightly lower in order to pay off the additional costs of manually completing the distribution.
