The insurance coverage of public unit accounts depends upon the type of deposit and the location of the insured depository institution. All time and savings deposits owned by a public unit and held by the same official custodian in an insured depository institution within the State in which the public unit is located are added together and insured up to $250,000. Separately, all demand deposits owned by a public unit and held by the same official custodian in an insured depository institution within the State in which the public unit is located are added together and insured up to $250,000. For the purpose of these rules, the term "savings deposits" includes NOW accounts, money market deposit accounts and other interest-bearing checking accounts.

The insurance coverage of accounts held by government despositors is different if the depository institution is located outside the State in which the public unit is located. In that case, all deposits owned by the public unit and held by the same official custodian are added together and insured up to $250,000. Time and savings deposits are not insured separately from demand deposits.

As mentioned above, a political subdivision (through its official custodian) is entitled to its own insurance coverage. The term "political subdivision" is defined to include drainage, irrigation, navigation, improvement, levee, sanitary, school or power districts, and bridge or port authorities and other special districts created by state statute or compacts between the states. The term "political subdivision" also includes any subdivision or principal department of a public unit (state, county, or municipality) if the subdivision or department meets the following tests:

• The creation of the subdivision or department has been expressly authorized by the law of such public unit;

• Some functions of government have been delegated to the subdivision or department by such law; and

• The subdivision or department is empowered to exercise exclusive control over funds for its exclusive use.

The term "political subdivision" does not include subordinated or non-autonomous divisions, agencies, or boards within subdivisions or principal departments.

Again, a public unit (including a political subdivision) is insured through its official custodian. If the same individual is an official custodian for more than one public unit, he or she is separately insured for the deposits belonging to each public unit. On the other hand, two or more individuals are treated as one official custodian if action or consent by all of these individuals is required for the exercise of control over the funds of a single public unit.

An official custodian is an officer, employee, or agent of a public unit having official custody of public funds and lawfully depositing the funds in an insured institution. In order to qualify as an official custodian, a person must have plenary authority – including control – over the funds. Control of public funds includes possession as well as the authority to establish accounts in insured depository institutions and to make deposits, withdrawals and disbursements.

Deposit insurance coverage cannot be increased by dividing funds among several putative official custodians who lack plenary authority over such funds. Likewise, coverage cannot be increased by dividing funds among several accounts controlled by the same official custodian for the same public unit.

A special rule applies to funds held by an officer, agent or employee of a public unit under a law or bond indenture that requires the funds to be set aside to discharge a debt owed to the holders of notes or bonds issued by the public unit. A deposit of such funds in an insured depository institution is insured up to $250,000 for the beneficial interest of each bondholder. This coverage is separate from the coverage for other deposits owned by the public unit at the same institution. In order to obtain this special coverage, however, the deposit account must satisfy certain disclosure requirements applicable to deposits held by agents or fiduciaries. Specifically, the deposit account records of the insured depository institution must disclose the existence of the fiduciary relationship or the fiduciary nature of the deposit. In addition, the details of the fiduciary relationship and the interests of the bondholders must be ascertainable from the records of the depository institution or the records of the depositor maintained in good faith and in the regular course of business. See 12 C.F.R. 330.5(b).
