Again, as I indicated earlier in my testimony, our plan is based on very conservative assumptions. It contemplates no further plant closings beyond those we announced in our planning period. I would say that, as you know, the business viability is essentially very simple. It is the revenues that generate your cost structure, which leads to your profitability and your ability to pay, and also the financing that you get to finance your business.
On the revenue side, I can't stress enough how confident I feel about the products of General Motors, so I think that on the revenue side we'll be in good shape. I think that on the cost side we'll be in good shape. Therefore, I believe that we, to the best of our ability, have a plan that basically preserves this proportionality of production.
