Tree, DTCC updates their NSCC (the OTC subsidiary) Excel files once a month according to the website. I believe that all there is to it. What we don't want to see is TYTN on the list as a "DELETE." Usually, a failure to pay fees is the cause.
"DTCC, through its subsidiaries, provides clearing, settlement and information services for equities, corporate and municipal bonds, government and mortgage-backed securities, money market instruments and over-the-counter derivatives. In addition, DTCC is a leading processor of mutual funds and insurance transactions, linking funds and carriers with their distribution networks."
"DTCC's subsidiary, National Securities Clearing Corporation (NSCC), established in 1976, provides clearing, settlement, risk management, central counterparty services and a guarantee of completion for certain transactions for virtually all broker-to-broker trades involving equities, corporate and municipal debt, American depositary receipts, exchange-traded funds, and
unit investment trusts."
Penson remains our bogey, IMO!
I'd have replied sooner, but ran out of posts.
All the best,
