Fiduciary transactions are fundamentally characterized by the fact that a trustee or fiduciary acquires in his own name goods, assets or claims (receivables) at the instructions of the trustor or beneficiary and manages the assets held in trust in the interest of the principal and in accordance with his instructions. The trustee or fiduciary acts in his own name but for the account and at the risk of the trustor or beneficiary. Fiduciary transactions performed by a bank in the form of money market investments or as fiduciary loans are effected or granted in its own name, but in response to a written order, exclusively for the account and at the risk of the customer (fiduciary investments, fiduciary loans). The principal bears the currency, transfer and del credere risks. Fiduciary transactions rank among off-balance-sheet business but are shown by banks under the line. In the wider sense of the word they also include all other transactions entrusted to a fiduciary or trust company.

Попечителски сделки – сделки, при които сметките за ценни книжа, предмет на
сделката, се намират при ИП, различни от ИП/брокери, чрез които се сключва
сделката на пода на борсата.
За осъществяване на сделка при подобни случаи, брокерът-продавач на
