Regarding TD Ameritrade
I think it is more likely your choice in brokerage firm. I use Charles Schwab and I had called them regarding the original offering. I was told that it had to be done by that Monday (when the expire time was Wednesday). I was told at the time to just call back on Friday and check. Everything was fully "loaded" into their system on that Friday as promised. I actually did throw some money into the rights offering just because I am in so deep I figured it wouldn't matter all that much. Funds were removed from my account on Tuesday as they told me it would be. So, I don't think it is (in THIS case) Navidea's or Maxim's fault but the brokerage. Just my 2 cents.
