PAP.10.6.030 Compliance Requirement
The Tribe, tribal entities, or a consortia receiving advance payments under the ISDEAA or the Tribally Controlled Schools Act may invest advance payments (some recipients refer to these advanced payments as "deferred revenue"), before such funds are expended for the purpose of the grant, contract, or funding agreement, so long as such funds are:
(a) Invested only in obligations of the United States or in obligation or securities that are guaranteed or insured by the United States, or mutual (or other) funds registered with the Securities and Exchange Commission and which only invest in obligations of the United States or securities that are guaranteed or insured with the United States; or
(b) Deposited only in accounts that are insured by an agency or instrumentality of the United States, or are fully collateralized to ensure protection of the advance funds, even in event of a bank failure (25 U.S.C 450e-3).
