Such collateral securities, or securities substituted therefor as collateral, shall at all times be at least equal in face value to the amount of trust funds so deposited, but such security shall not be required to the extent that the funds so deposited are insured by the Federal Deposit Insurance Corporation or other federal insurance agency. The requirements of this subsection are met when qualifying assets of the association are pledged in such manner as to fully secure all trust account funds deposited by the trust department of the association in another department of the association.
