Simple Income III is an option available to owners of the Masterdex X indexed annuity.
There are 3 options available through the Simple Income III rider. The third option ("Income Option 3") allows the withdrawals or income payments to increase up to 10 percent each year.
The potential increase in the income level is based on the consumer price index (CPI).
Not entirely sure if there is a 1-to-1 relationship between any rise in the consumer price index and the increase in income payments.
Income payments can last up to 20 years from the date that they begin.
Not entirely perfect, but inflation adjusted lifetime income is certainly a step in the right direction.
