If we go back to the retirement income security benefit, again it's based on a calculation of 70% of the income support plus permanent impairment allowance benefits received at the time the veteran turns age 65.
If the veteran was receiving earnings loss benefits from Veterans Affairs and he or she was also receiving the permanent impairment allowance or the PIAS, they would be added together and the veteran would be eligible for 70% of that amount less income received from prescribed sources. Prescribed sources, as we noted earlier, would be other income streams like Canada pension, like superannuation that the member or the veteran might be eligible for.
In other words, it's simply that the intent of the program is designed to ensure a minimum income level and 70% is the calculation.
