Thanks Stephen. Hi Nicola. Yes, I will just add one point to Steve before I go to the buyback question. I think. Just to clarify too, our definition of backlog, the definitions are not consistent in this industry. So I just want to make sure you understand that, in my opinion, we have the most stringent definition on how we define backlog. It must be growth. It must be contractually secured over $5 million. It means we don't put MoUs. We don't put LoIs. We don't put merchant-only type projects. So to Steve's point, even within our base CapEx spending, a little less than half of that is for growth and for very good growth. For on sites below $5 million, some of these small on-sites were put in places like glass and some other strong growing markets like paper. We also are seeing a lot of good growth opportunities in there that may not meet our backlog definition but we see good returns relative to the risk and things we are pursuing. So I just wanted to make sure when you think about the capital we are spending on growth, there are two elements. There is what fits our fairly stringent backlog definition, but then there is a substantial portion of growth that we also have that we are pursuing in the base CapEx. Regarding the share buybacks, yes, just a couple points to make. First, the expiration, I wouldn't look too deep into that, into February. That's more of a technicality that's required under the European MAR requirements. In reality, I think a better way to think about how we look at buybacks is that they are an integral part of our capital allocation policy. As you probably well know, we always look to maintain our A rating and grow the dividend every year. And then after that, our priority is to grow and it's to invest in growth. It could be acquisitions, could be decaps, could be projects. But we always tend to have a lot of excess capital left over and then with that excess capital, that goes to buybacks. So our expectation is to continue to have open buyback programs. As far as why we were probably a little bit less on track than the $6 billion, obviously as you know, with COVID, we turned it off for about a quarter, just in light of the items we discussed at that time in Q2. But this is something that we have been in the market now every day since August, since we started back up. And our approach is to be in the market every day and then when we see opportunities we will go heavier at times. But this is something that will be an integral part of our capital allocation policy.
