So Roche makes a - having investment resource wise into the asset, we have a partner who is also investing very heavily asset resource wise into the asset and we share the, and we share the results. The second type of and another type of transaction similar to that was a deal there with a company called [
PharmaDeals ID = 14122]Aspreva, right much different company than GSK obviously. And in the United States we actually had a marketed product CellCept which is a $2 billion year turn over at this point globally in a the approval for transplantation, we felt that, that was the right partner we were hoping to actually get approval for autoimmune diseases and they took full risk for autoimmune disease, did not work out we cannot get the approval but I think the principal is sound actually in the deal need, the critical our component there was again external investor in a product that we are actually resourcing. The second type of compartment that we think about in terms of outside investors in products that we are resourcing would be a secure financial investor and there as David had mentioned that the cost of capital is high and you know we are a pharma company and our investors do expect us do expect that we are going to be investing the money that we derive of our operations into our prioritized products so it's hard to justify, but can be we always been a high cash floated company we just need make the acquisition you've seen me into acquisition may be that changes, but the cost of capital is higher and we have not actually executed one of those deals yet. The third type of compartment that I see on that side of the equation is hybrid deals and I think one of the leaders in that space is the TPG-Axon model so it's a combination of the group that has substantial financial resources but can also put to play in a development capability and we work very closely with Quintiles [
PharmaDeals ID = 20431] and that's the third type of deal that we'd see which is an externalization of our generating external investment into our internal products that we are still resourcing we are gonna get that executed at Roche one of those deals but there is certainly something that gets presented to us quite often and something that we would think about. The other side of the equation or the other compartment is just is what we or I'd called externalizing our internal innovation so those are assets that we were no longer going to be resourcing moving forward or we actually want to find external homes for the assets and there again I would see it is three types so there is licenses somebody may be approaches us for an asset that we have typically it's going to be an early stage development and may be the preclinical asset based upon some insights that that group has and but a deal to get a licensing deal on some the return to Roche could be through many different mechanisms, it can be through equity, it can be through milestones, royalties if it's a you know operational company Newco, may be an upfront associated with it, but you know we are actually pretty flexible but in terms of that type of constructions. The second type is where we actually utilize our internal technologies as to trade and as will be liquids, so maybe we have like constellation technology or compounding of our library which is an interest too good to work with then may be like we pass some other technology that might be interested for us to work with and may be that group has some other technology that might be of interest to us to work with in-house, but it's hard to find that match but we certainly like to have a discussion. And then the third type is a spin off, a pure spin off where we actually move about all of those people out of the organization with assets and the other classic example of that, we have done recently with Basilea [
PharmaDeals ID = 22931] which was our anti-fungal and Vitamin D spin out and Bioxel [
PharmaDeals ID = 15281] which was also doing some Vitamin D work which was actually a Italian R&D site that we had and from very talented people and that they've created a lot of value over the years. So those sorts of the compartments that we have, we think about managing our assets and is a group we actually call asset management.
