Idaho Code § 67-1304: Custodians of federally insured deposits.

Whenever the time deposits made by the state treasurer with financial institutions may be insured in whole or in part by the federal deposit insurance corporation, the federal savings and loan insurance corporation, or other federal program, and the amount of insurance available may be affected by the appointment of multiple custodians, the state treasurer shall appoint multiple custodians in such a manner as to maximize the amount of insurance provided.
