The answer to your latter question is yes. But on the former, money required for maintenance of the spans comes from operating revenues, but I can tell you that all of my toll revenue is first pledged to the bond holders. The bond holders get paid before I do. The bond holders get paid before the bridge is painted. The bond holders get paid before we build facilities for Canada Border Services Agency.
What I use to underwrite general maintenance and our payrolls, our IT department, and all of the things that are required to operate three international crossings is in large part our non-toll income. We receive more than $4 million a year from the Government of the United States of America for the lease of the facilities for customs and border protection, USDA, and what have you. There is normally an agreement between the owner of the bridge or tunnel and the operators of the duty-free shops, whereby the bridge owners get a percentage of their sales. We have a private currency exchange operator on our bridges, and we get a percentage of that.
The third part of it is that we have built significant reserves in the past ten years as we have been getting ready for significant capital improvement. Those reserves have also thrown off some interest income, but we're about to deplete that, so you're right--then we go into the financial markets to float additional bonds for any additional capital construction that we need to accomplish.
