As you can imagine, with a workforce the size of the agency's, we do have departures and hiring. Occasionally, there are vacancies, absolutely, and that fluctuation is also impacted by the seasonal business that the agency undertakes. There are certain areas of our inspection activities, for example, that are seasonal in nature because of the nature of the products that they're associated with, so we do see seasonal variations in terms of our workforce.
Of course, we respond to departures with hiring, but it isn't instantaneous. So, yes, there are occasionally vacant positions in the agency.
