So, yeah I think one of differences probably between Roche and Pfizer from what I am hearing now is Pfizer has a very large a very large basket of products that have potential to be externalized. I think we have just a smaller basket Roche likely. So most of our work with externalizing our assets well we work with venture capital groups and like are really with late preclinical, early clinical stage assets we have a few, we I mean not all of them are gonna work and we know not all of them are gonna work, we have a few. What we try to do is focus our efforts that we are working with groups who were networked with they know what's new in what processes, it works " our bigger successes have been where we move the assets out to the companies where somebody is in the company who actually had touched and felt the asset at some point in the past, examples are Evotec [
PharmaDeals ID = 24561] you know we've had a series of licenses licensing deals with Evotec where we have actually externalized quite a number of technologies, compounds, libraries and even products Evotec, we've recently now licensed one back that's a huge success for us. Synosia [
PharmaDeals ID = 26167] is an example of a company that formed out of Versant Ventures, the CEO is actually a former ex-Roche person who had a deep understanding of the basket of CNS assets and we are looking to actually to generate our return from that " from the actual development of the assets over there, we don't have upfronts it's not a heavy owners deals in terms of the value that we received early but clearly as the assets develop we believe that we will get value, we've actually constructed rather a elaborate deal with them in terms of what assets we have rights to, what assets we have preferential rights to what assets we have really have nothing over than a royalty stream another group is a Flexion which is also one out of Versant Ventures you know kind of is going to prefect that idea hopefully going beyond CNS and other indications but for us the return comes on development, we find that we are generally you know in our small basket we generally not correct when we try to predict that asset A is the one that's to get development versus asset B so we really let the market tell us which one should get developed, we do not let option processes for those types of programs, we are really looking for capabilities and vision to kind of develop the asset and somebody again championship in making sure that somebody has had some type of touch or feel to the asset makes a huge difference in our experience.
