Good morning, Raj. I hope you are doing well and happy to talk about that, because I think it is really a very intuitive question. Certainly, you are probably used to pharmaceutical launches and some of the gates that kind of control how pharmaceutical comes out and coverage is certainly one of those gates. We will be - we feel we will be well prepared to launch, but as you say contracts down the channel for where we need channel partners to move the product, but there are some of the gates. One of them is the pass-through application to CMS. So, with this type of radiopharmaceutical product, you were required after approval to put application in through CMS for designation and recognition of counsel. It's not a question of whether it will be approved, but it is a question of just from the function of putting the application and there could be a 60-day gap between the approval date and when you get that application and then, when the application comes back is approved. So, I think you do need to gate the uptake based on that. If you look at the population here, this is a significant Medicare population of patients in the market that I was referring to. Well, average age of diagnosis - at time of diagnosis for prostate cancer is below the Medicare age. These gentlemen, fortunately live for 18 to 20 years. So, especially if you're talking about our addressable population, which is mainly biochemical recurrent. These are gentlemen who have been already within the treatment paradigm. And so, many of them will be of Medicare age. So, I think we need to date that way. The other gating factor is, the coverage you have across the U.S. population and with radiopharmaceuticals that are PET manufactured, when you submit your application, within your application you submit for simultaneous approval of PET manufacturing centers. These are – each site is considered an approved manufacturing site just by nature of how the product is produced as I described it in my comments earlier. And so, what is very typical with these products is, you submit with a group of PET manufacturing facilities and then, immediately at approval, you submit the next - I'll call them a basket or group of PMS that will then also be considered and approved by the FDA as additional supplemental manufacturing sites and you can do that on a six-months basis. Now there are different regulatory pathways that allow you either quicker access to those approvals or more standard review and we intend to take availability of all of them. But that will also present gating as to what percent of the total U.S. addressable population will have - I'll say, access to immediately at approval. What I will say is that, we are confident that by six months out, we will essentially be covering the U.S. population, but from the zero to six-month period, it is somewhat of a ramp.
