Loans or extensions of credit secured by a segregated deposit account in the lending bank are excluded from the calculation of the general lending limit set forth in WAC 208-512A-010, subject to the following terms and conditions:

(1) Deposit accounts which may qualify for this exception include deposits in any form generally recognized as deposits. In the case of the secured loan, the bank must establish internal procedures which will prevent the release of the security.

(2) The bank must ensure that a security interest has been perfected in the deposit, including the assignment of a specifically identified deposit and any other actions required by state law.

(3) A deposit which is denominated and payable in a currency other than that of the loan or extension of credit which it secures may be eligible for this exception if it is freely convertible to United States dollars. The deposit must be revalued at least monthly, using appropriate foreign exchange rates, to ensure that the loan or extension of credit remains fully secured. This exception applies to only that portion of the loan or extension of credit that is covered by the United States dollar value of the deposit. If the United States dollar value of the deposit falls to the extent that the loan is in nonconformance with this exception and exceeds the general twenty percent limitation, the loan must be brought into conformance within five business days, except where judicial proceedings, regulatory actions, or other extraordinary occurrences prevent the bank from taking such action. This exception is not authority for a bank to take deposits denominated in foreign currencies.
