Ignacio: Gloomy tales order nolvadex uk Sure so let me start and then I’m going to ask Pat to comment as well. So today we have three years at specialized sales force, number one our EUC business, number two our network virtualization business associated with NSX, number three our vCloud hybrid service business where we have a specialized sales force who are skilled at selling more of a service orientation as opposed to a product or license sale and lastly you know as we announced in Q2 we have decided to put a specialized sales force in place around management and automation because we see our cloud management business growing as I said earlier is one of our fastest growing businesses. And we look at these specialized sales force as an augmentation to the core sales force that VMware has and we bring in people with domain specific knowledge of each of these technologies and then in a lot of cases we focus on technical talent because we think it's the technical folks in these sales organization, my guess ease in professional services who brings incremental value to our core sales force. So that’s our philosophy and the mentality and it's working out well in 2013 and we expect a lot of those investments this year to pay off for us in 2014. Pat any color?
