Utah Code § 15-7-10

Obligations issued by public entities under the laws of another state, the District of Columbia, or by territories or possessions of the United States, which are in registered form, whether or not represented by an instrument, and which, except for their form, satisfy the requirements with regard to security for deposits of money of public agencies prescribed pursuant to the law of Utah, are deemed to satisfy all such requirements even though they are in registered form if a security interest in such obligations is perfected on behalf of the public agency whose money is deposited.
