Custody of Customer Assets

Longbridge does not directly hold or safeguard customer securities or funds. All customer securities and cash held in brokerage accounts opened through Longbridge are custodied by Apex Clearing Corporation, which performs custody, clearing, trade settlement, and account recordkeeping functions.

You will receive account statements, trade confirmations, and other required account documentation from Apex, which reflect the official books and records of your account. Longbridge provides the trading platform, account interface, and customer support services, while Apex performs all clearing and custodial functions.

Important Notes

  • SIPC protection applies only to the custody and safekeeping of securities and cash held in a brokerage account, not to investment performance or market losses.
  • Cryptocurrency assets are not securities held in a Long Bridge Securities LLC brokerage account and are not protected by SIPC.
