RE: stock broker Drillquip, I also noted the absence of the question and answer session on the recording of the webcast.
I was unable to listen to it at the time it actually took place and I noticed that other posters referred to questions and Don's answer (in particular his error related to US holders). I have seen this on other companies where they for whatever reason drop the unscripted questions and answers.
It is disappointing; but I see no way to force companies to post the most interesting parts and it is just a problem if we cannot be listening in real time.
