The Third Layer
At this point, one ventures beyond the normal notions of diversification by bringing the concept of time into the equation. The future might hold unforeseen stumbling blocks and/or opportunities which might not currently be real or expected. The management of your future income stream is paramount.
Should you at some point run into a dire situation where extra income is urgently needed, such as a medical condition not fully covered by your medical aid, the flexibility of the living annuity income withdrawal might emerge as a solution. Since the income may be altered once a year, you will then have the option to increase the income from the living annuity for a year or two to cover the extra expenses.
Although this might not be an ideal solution, the flexibility can solve a serious problem. The living annuity therefore can double as an emergency fund for the future.
Another opportunity that might arise is the purchase of a second life annuity somewhere in the future. Guaranteed rates in the future, when you are older, might present another bite at the guaranteed apple, but at a far better rate than might currently be the reality. Instead of locking all guaranteed rates into a single event at retirement, the combination allows for the diversification of entry points into a guaranteed environment.
Some platforms offer the opportunity to split the remaining living annuity into another combination, which means the flexibility of a portion in a living annuity does not need to be fully discarded at that point. However, platforms that do offer this functionality are very limited, so due consideration of the platform used is necessary to allow the third layer diversification.
