The issue of provenance is certainly an important one, and has become increasingly important as attention has been paid both to Nazi-era changes of ownership and to some of the current issues of perceived looting. Part of the evaluation process for an individual exhibition is an examination of provenance. So that's part of the process and part of the documentation that needs to be supplied in the plans for the exhibition.
The same thing is true when you speak of material, for example, that may be composed of elephant ivory or an endangered species. The examination of the plan for an exhibition is actually an object-by-object examination, with a full description. The peculiarities or the particular conservation requirements of individual objects are part of the risk assessment. As part of that, the core documentation would include the material. That's an opportunity to use that.
We certainly do look at the implications for things like the Cultural Property Export and Import Act, in the event that there's any crossover, and the Customs Act. That's all part of the evaluation that's conducted.
