Mr. Fergal Mulligan:

I will ask Mr. Neary to deal with this. We did a lot of work on this when examining the contingency options in late 2018 and early 2019. We dealt with a whole suite of contingency options. I instructed those concerned that they needed to be as aggressive as they possibly could in terms of a new procurement process if, for whatever reason, the Government decided to embark on such a process. Mr. Neary did a considerable amount of work on this, considering various models and options. We identified a period of around 37 months using a very aggressive timeline. Mr. Neary might break down the components.
