Ms. Stronach, that is set by our enabling legislation. In the instance of the Niagara Falls Bridge Commission, we were a creation of the United States Congress in 1938, and if you'd indulge me for just a moment, this comes from the original 1938 legislation:
In fixing the rates of toll to be charged for the use of such bridge, the same shall be so adjusted as to provide a fund sufficient to pay for the reasonable cost of maintaining, repairing, and operating the bridge and its approaches under economical management and to provide a sinking fund sufficient to pay the principal and interest of such bonds as the same shall fall due and the redemption or repurchase price of all or any thereof redeemed or repurchased before maturity is herein provided. All tolls and other revenues from said bridge are hereby pledged to such uses and to the application thereof hereinafter in this section required.
It does go on in some detail, but what I'm trying to demonstrate is that there is very specific direction to us to only collect that toll that is necessary for our core responsibility. I think that you'll find similar legislation in most of the quasi-public entities. I know that at the Buffalo and Fort Erie Public Bridge Authority, they have very similar language in the legislation.
