With regard to the voucher policies in the United States and Europe, both the United States Department of Transportation and the European Commission had indicated that airlines would be absolutely required to provide refunds. I will say that our understanding, to date at least, is that this has not been fully enforced in the United States, and that although the European Commission took the position it did, a number of key European Union members are not requiring, at least to this point, their carriers to actually provide refunds.
