I'll start and if others want to join in, please do. The important thing about the benefits for the elderly is that they are statutory votes. So they're actually protected in legislation as opposed to being voted on by Parliament each year.
The benefits themselves are a function of the number of recipients who are of the appropriate age, and the payments that they receive on a biweekly basis. Those benefits are fully indexed to the consumer price index, so they will go up based on the consumer price index.
The only thing I should add to that in terms of forecasting is that they did go up, but they didn't go up quite as much as we had forecasted simply because the CPI was lower than anticipated. So when we actually did the math, it worked out to be a little less than anticipated. They are fully indexed to the consumer price index, and that's why they're protected, and that's what drives the increase. Those numbers will continue to go up based on our population trends.
