Some independents have access, but most bigger broker/dealers I've spoken with do not offer T/A at all (I always ask them out of curiosity)
I primarily work the B/D market and I don't know of a major indy who doesn't offer Trans...they also likely offer Met, Pru, AXA, Allianz, AIG, LGA etc., all of who are larger than Aegon (at least in assets, which is the metric which I believe you are using to measure size).
I know that WFG has some exclusive products but how do they compare to the ones that most of us on this forum can access? Genuinely curious....
