It's one of the reasons that we're facing a higher volume. In particular, if you look only at breach notifications, previous to November, organizations could voluntarily report; now they have to when there's a material breach. The volume of these reports has increased fivefold since November. That's clearly a reason for the increased volume. It's not the only one, but it's an important one.
