Review how reserve deposits, qualified institutions, withdrawals, and Rule 15c3-3 exemptions work on Series 27.
After the reserve computation is prepared, the FINOP has to know what happens operationally. Series 27 therefore tests how special reserve bank accounts are established, what counts as a qualified deposit or institution, how withdrawals are limited, and when the firm may claim an exemption from parts of the Customer Protection Rule. This is not just a bank-account topic. It is a segregation-and-discipline topic.
The exam usually rewards candidates who respect the purpose of the reserve account. It exists to ring-fence customer or PAB protection, not to serve as a flexible funding source for the firm. When a question mentions withdrawals, deposit timing, or special-account documentation, the safer answer is the one that protects the segregated function first.
| Topic | What matters most | Common exam trap |
|---|---|---|
| Qualified institution and account setup | The account must be established and maintained in the rule-defined way. | Treating any bank relationship as sufficient. |
| Deposit timing and amount | Reserve deposits must be made and maintained according to the computed requirement. | Thinking the account is flexible if the firm expects money to arrive later. |
| Withdrawals | Funds are not a general operating cushion and cannot be moved casually. | Treating the reserve account like an internal liquidity pool. |
| Documentation | The firm must be able to show how the account is established, funded, and maintained. | Assuming the reserve account speaks for itself without record support. |
| Exemptions | Exemptions depend on the firm’s actual business model and handling of customer assets. | Applying an exemption casually because the firm handles little customer property. |
Series 27 normally prefers the answer that preserves full customer-protection discipline unless the exemption facts are clearly and cleanly satisfied.

The core instinct is simple: uncertainty usually pushes the FINOP toward full protection, not toward aggressive exemption use.
A firm wants to use funds from its special reserve bank account to cover a temporary internal cash need and expects to replace the amount shortly afterward. What is the best Series 27 reaction?
A. Treat the reserve account as a general funding source if the firm plans to replace the money quickly
B. Allow the withdrawal if senior management approves it informally
C. Ignore the issue if the reserve computation was accurate the week before
D. Treat the reserve account as segregated customer-protection support and review any proposed withdrawal under the rule’s protective limits rather than as ordinary firm liquidity
Answer: D. Series 27 tests whether the FINOP respects the ring-fenced purpose of the reserve account. Temporary firm convenience is weaker than the customer-protection function.
