I'll answer this one.
You're correct that the drop-outs still remain in the base plan. With respect to the general drop-out, I can say that it is built into the structure being enhanced, so it's still there. Today, you have a base plan in which your contributions start at age 18 and end at age 65. You're talking about 47 years. You have a general drop-out of 17%, which drops out eight years, so that brings you to your best 39 years. The enhancement doesn't have that drop-out per se, but it takes your best 40 years. It's very similar to the general drop-out that is put in. There's also a plus-65 drop-out. You take in the base plan your contributions above age 65, and you replace your lower earnings prior to 65. That is also built in, because, again, you take your best 40 years.
With respect to the child-rearing and disability drop-outs, they will remain in the base plan and they will still protect individuals for eligibility purposes and continue to enhance their benefit.
With respect to the enhanced portion of the plan, these are not duplicated in the enhanced portion of the plan, as this plan is closely linked to the individual's contributions. As Glenn mentioned before, it's very similar to a workplace pension plan. It aligns with the full funding provisions by minimizing the subsidies and also by minimizing the intragenerational and intergenerational transfers.
