Hi, yes, I was well pleased with all the answers to my questions and the help that I got from the provider, considering it was a telephone conference. And he pretty much answered all of my questions very professionally and we got a good connection in respects to what information we both needed at the time. And it was very professionally done. So I just want to commend him on the questions he asked and also the response to the questions I had too. And that's it.
