They could be Canadian. Of course, in that category, Canadians would not derive the tax benefit, but they could purchase the bonds, if they found them attractive. Probably most of my bonds are held by Americans.
In the matter of the Blue Water Bridge Authority, I know that their bonds were issued in Canada.
In terms of rating, I can't tell you that everyone is the same because, as I indicated earlier, there are smaller and larger entities, and they are all over the map in terms of their financial strength. Our bond rating is an A, and the Buffalo and Fort Erie Public Bridge Authority's rating is an A minus, which are very attractive ratings from the agencies.
