How does the income risk rating take into account an income drawdown product with a guaranteed income stream?

The income provides a guaranteed yield each year which increases the minimum sustainable income that can be achieved from the product, and at the same time reduces the income at risk percentage, which is the percentage that we might expect the income to drop by after 3 years, thus reducing the risk rating of the product.

If the guaranteed income increase matches the sustainable income increase of RPI/None then the reduction in risk will be greater.
