let's bring in bill mcdermott the company's ceo to discuss it in more detail bill, always good to have you. i want to start off on something that might be pressuring the stock and it's not related to your numbers, but to your head of sales and a planted departure. it was noted in the call sort of halfway through the call, but it did seem to take some investors by surprise. i wondered if you could discuss it in light of the fact that it may be pressuring your shares. >> right as you know any change to the capital markets raises questions, right so david schneider is a 35-year sales veteran, has been with the company for nine years, had a great career, the first day i met him last year he said he was going to retire at the end of 2020 so kevin hafferty has been running the number and leading sales for us for six years so there really is no change and david is staying with me until the end of the year and we have an outstanding management team, there's no fundamental change to the coverage model, who is running the number and the execution with customers so they need not worry we're good.
