Thank you, Mr. Chairman. The way this is typically handled for a project is by having projects implemented over a period of time where you have one year in which you do the planning for a project and the next year you enter into the detail design and then the following year you begin construction. That kind of a typical implementation schedule allows you to have better information as the project progresses.
Certainly in the planning stage for a project and the design stage it gives you the opportunity to make sure that you do have the project properly reviewed and all of the permitting in place before construction actually proceeds. If costs arising out of that become much higher than anticipated, you still have the opportunity to review whether or not the project should proceed at all. Along the way it may mean variances in the costs for the projects, but through our financial review process that we do have, we have some flexibility to make adjustments to project budgets as the work develops.
Hopefully, we strive for minimum variances in project costs, of course. Thank you, Mr. Chairman.
