 So, CTO meetings started almost in the year 2000, where it was found to be an opportunity for industry and operators at the executive level to come and discuss among themselves and with the TSB director important standard issues and how the ITU could be organized to address those urgent industry needs. In the context of that CTO meeting we have seen many new groups get formed because of the CTO meeting. We saw new standards emerge because of the CTO meetings and it really allows for that combination of the top down at the executive level plus at the engineers level in each company to have that synergy between what's the industry, where is the industry going, what is the need of the operators and merge that with the contributions that come to our study groups. So it's a very healthy way to have this dialogue once a year on a global level in conjunction with the telecom world. So, this year unsurprisingly 5G was the topic of most discussion and looking at 5G from various angles. We looked at 5G security, 5G quality of service, 5G deployment scenarios, early deployments and the learnings we have from 5G, the use of machine learning and artificial intelligence in 5G and that took pretty much a lot of the discussion, the time of the discussion. We also started looking beyond 5G what are some of the fiber optic network infrastructure and protocols required to not only meet the requirements of 5G but beyond 5G. We looked at the infrastructure sharing becoming yet more important in a 5G era and we also looked at the business models of deploying 5G, especially in developing countries. What would trigger a developing country operator to move from 4G to 5G? So all of those discussions really were of the top quality because the players and the people sitting around the table are the CTOs who have to make those technical decisions and are the ones faced with the challenges. In addition we had the study group chairman and the focus group chairman around the table so they took first hand the input of the executives of what's keeping them up at night and what are the next things that these study groups need to work on. We also had the TSAC chairman now we're in a year where we're preparing for WTSA, the World Telecom Standards Assembly and one of the things the assembly will be looking at is the new structure of the ITU and an observation was made during the meetings that in the last 12 years the structure of the study groups hasn't really been changed much and given all the changes in the industry and the technology there was a call to look at that with more attention and more focus this time around in WTSA 2020. All right, so the immediate impact there is some short-term elements that where the study groups and the focus groups are taking this input from the meeting to enable new elements for example the 5G security that was welcoming of the Ottawa Accord that looked at exchanging threats and at the same time in study group 17 we have a new standard that would enable security threat exchange and how a playbook would run in a network operator in a 5G era. So some of those are some of the quick wins but in terms of long-term strategy I think it was clear that the study groups might have to restructure in a more dramatic way to address the digital convergence in the digital era. The fact that ICT is being used in various verticals like healthcare, transportation and so on and so forth might lead to some new thinking on how our study groups might be structured.
