Mr. Speaker, the rate is set based upon the costs of the additional air security measures that are being adopted. As was made clear yesterday in the budget, as well as in the documents we circulated in November, the ability to reduce the tax is based on the fact that we are moving to a full accrual accounting system, which will enable us to apportion the cost over the life of the assets being acquired.
