First of all, we have the business planning process, both for capital projects and for programs and services, that normally will catch these if we have enough advance warning that there is an urgent situation developing. During the year, it may happen that a building will be condemned for some reason or some other issue arises. Then we have to look at each of those cases. If it's a matter of life being endangered or a major asset being endangered or inability to deliver programs, we have to look at it and assess whether it is something we want to deal with as an emergency. If it is, we make that decision and we bring it back here through a supp process. Other than that, anything we have enough warning on, we are able to put into business plans.
