Rules relating to the “official custodian”—(1) Qualifications for an “official custodian”. In order to qualify as an “official custodian” for the purposes of paragraph (a) of this section, such custodian must have plenary authority, including control, over funds owned by the public unit which the custodian is appointed or elected to serve. Control of public funds includes possession, as well as the authority to establish accounts for such funds in insured depository institutions and to make deposits, withdrawals, and disbursements of such funds.

Official custodian of the funds of more than one public unit. For the purposes of paragraph (a) of this section, if the same person is an official custodian of the funds of more than one public unit, he or she shall be separately insured with respect to the funds held by him or her for each such public unit, but shall not be separately insured by virtue of holding different offices in such public unit or, except as provided in paragraph (c) of this section, holding such funds for different purposes.

Split of authority or control over public unit funds. If the exercise of authority or control over the funds of a public unit requires action by, or the consent of, two or more officers, employees, or agents of such public unit, then they will be treated as one “official custodian” for the purposes of this section.

Public bond issues. Where an officer, agent or employee of a public unit has custody of certain funds which by law or under a bond indenture are required to be set aside to discharge a debt owed to the holders of notes or bonds issued by the public unit, any deposit of such funds in an insured depository institution shall be deemed to be a deposit by a trustee of trust funds of which the noteholders or bondholders are pro rata beneficiaries, and the beneficial interest of each noteholder or bondholder in the deposit shall be separately insured up to the SMDIA.
