You had a number of questions. I'll try to respond to a few of those.
The number of cases more than 10 years old would be very few in any line of business. We can certainly provide you the overall backlog by line of business and as well by year. We have the backlogs or inventories in all the various categories; that's available to us.
Over the past few years, the inventories have come down in a number of areas very significantly. I shall point to the federal skilled worker inventory, which was at more than 600,000 in 2008; it's now at 25,000. Parents and grandparents has now been reduced 70% since December 2011. We talked about the live-in caregiver inventories as well.
In terms of new work, much of the constraint about backlogs has been the levels space that we have had; in other words, the number of applications that we were to process to meet our levels plan. The department has consistently met its levels plan, and we have worked within it.
