According to FINRA, David John Taddeo was assessed a deferred fine of $7,500 and suspended from association with any FINRA member in all capacities for four months for participating in private securities transactions without firm notice, settling customer complaints without firm knowledge, and making false attestations on compliance questionnaires.

Taddeo participated in private securities transactions with three customers who invested a total of $255,000, without providing prior written notice to his member firm. FINRA rules require representatives to provide written notice to their firms before participating in any private securities transaction. This requirement, often referred to as the "selling away" rule, allows firms to supervise these outside activities and assess whether they present conflicts of interest or suitability concerns.

Taddeo's participation included introducing customers to the investment opportunity, providing information regarding the company to customers, and assisting two customers with liquidating investments in their brokerage accounts at the firm to generate funds for the investment. While Taddeo did not receive any commission or other remuneration for the investments, his active participation in facilitating the transactions required firm notice.

The investments appear to have been promissory notes, which are debt instruments where the issuer promises to repay borrowed money with interest. Promissory notes sold outside the supervision of broker-dealer firms have been a significant source of investor fraud. Many fraudulent schemes have used promissory notes as vehicles to misappropriate investor funds.

Compounding the private securities transaction violations, Taddeo falsely attested on annual compliance questionnaires that he had not offered, issued, or participated in private securities transactions or promissory notes outside his firm and that he understood he could not direct customers to investments not approved by his firm. These false attestations meant the firm had no reason to suspect Taddeo's involvement in the transactions.

After two of the three customers experienced problems with their investments, Taddeo settled their complaints without the knowledge or consent of his firm. Taddeo personally repaid these two customers the amount of their original investment in the promissory notes. While this repayment limited customer harm, settling complaints away from the firm violates FINRA rules.

Firms are required to report customer complaints that meet certain thresholds to FINRA and to maintain records of all written customer complaints. When representatives settle complaints privately without firm knowledge, it prevents firms from fulfilling their reporting obligations and may allow problematic patterns of behavior to continue undetected.

Taddeo again made false attestations on annual compliance questionnaires, stating that he had not settled customer complaints away from the firm. The firm only learned of the customer complaints and Taddeo's settlements when the third customer (who had not been repaid) complained in writing to the firm.

The suspension is in effect from January 5, 2026, through May 4, 2026.

For investors, this case illustrates the risks of investments offered outside the brokerage firm. While not all private securities transactions are fraudulent, they lack many protections that apply to registered securities.
