Your link DOES NOT support your contention that there are delivery issues with Telvue. In fact it is the opposite. Per Finra and Regsho this security is not a threshold regsho flag nor is it flagged under rule 4320. I've included a few links to support my position. http://www.failstodeliver.com/datadump.aspx
I'm a lawyer, not a stock broker, but this seems very elementary to me, although if necessary I'll see if I can catch a poster named Big bake who is an expert on this and he can explain much better than me.
