In the first instance, we're talking about identifying the costs. There are many elements to the HSA, the wholesale access agreement, such as technical arrangements, how many points of interconnection, how it works and which facilities are included. It's a very complex matter and there are multiple elements. The costing of wholesale service is but one.
With respect to overall rates, between 2010 and 2015, rates were going up at a very rapid rate—between 30% and 40%, as I recall. The commission has taken numerous steps to intensify competition, including the establishment of the current HSA arrangement. That had the effect of stopping those increases, and rates flattened out. They increased slightly sometimes or decreased slightly, and you saw competitors' market share grow, and it has continued. Then we had to make determinations on wholesale costs.
You've said several times “increasing the cost”. No—determining the final rates based on costs, and that was what we did, as I've said several times now and corrected again.
