159-26. Accounting system.

(a) System Required. - Each local government or public authority shall establish and maintain an accounting system designed to show in detail its assets, liabilities, equities, revenues, and expenditures. The system shall also be designed to show appropriations and estimated revenues as established in the budget ordinance and each project ordinance as originally adopted and subsequently amended.

(b) Funds Required. - Each local government or public authority shall establish and maintain in its accounting system such of the following funds and ledgers as are applicable to it. The generic meaning of each type of fund or ledger listed below is that fixed by generally accepted accounting principles.

(1) General fund.

(2) Special Revenue Funds. - One or more separate funds shall be established for each of the following classes: (i) functions or activities financed in whole or in part by property taxes voted by the people, (ii) service districts established pursuant to the Municipal or County Service District Acts, and (iii) grant project ordinances. If more than one function is accounted for in a voted tax fund, or more than one district in a service district fund, or more than one grant project in a project fund, separate accounts shall be established in the appropriate fund for each function, district, or project.

(3) Debt service funds.

(4) A Fund for Each Utility or Enterprise Owned or Operated by the Unit or Public Authority. - If a water system and a sanitary sewerage system are operated as a consolidated system, one fund may be established and maintained for the consolidated system.

(5) Internal service funds.

(6) Capital Project Funds. - Such a fund shall be established to account for the proceeds of each bond order or order authorizing any debt instrument and for all other resources used for the capital projects financed by the bond or debt instrument proceeds. A unit or public authority may account for two or more bond orders or orders authorizing any debt instrument in one capital projects fund, but the proceeds of each such order and the other revenues associated with that order shall be separately accounted for in the fund.

(7) Trust and agency funds, including a fund for each special district, public authority, or school administrative unit whose taxes or special assessments are collected by the unit.

(8) A ledger or group of accounts in which to record the details relating to the general fixed assets of the unit or public authority.

(9) A ledger or group of accounts in which to record the details relating to the general obligation bonds and notes and other long-term obligations of the unit.

In addition, each unit or public authority shall establish and maintain any other funds required by other statutes or by State or federal regulations.

(c) Basis of Accounting. - Except as otherwise provided by regulation of the Commission, local governments and public authorities shall use the modified accrual basis of accounting in recording transactions.

(d) Encumbrance Systems. - Except as otherwise provided in this subsection, no local government or public authority is required to record or show encumbrances in its accounting system. Each city or town with a population over 10,000 and each county with a population over 50,000 shall maintain an accounting system that records and shows the encumbrances outstanding against each category of expenditure appropriated in its budget ordinance. Any other local government or any public authority may record and show encumbrances in its accounting system. In determining a unit's population, the most recent federal decennial census shall be used.

(e) Commission Regulations. - The Commission may prescribe rules and regulations having the force of law as to:

(1) Features of accounting systems to be maintained by local governments and public authorities.

(2) Bases of accounting, including identifying in detail the characteristics of a modified accrual basis, identifying what revenues are susceptible to accrual, and permitting or requiring use of a basis other than modified accrual in a fund that does not account for the receipt of a tax.

(3) Definitions of terms not clearly defined in this Article.

The Commission may vary these rules and regulations according to any other criteria reasonably related to the purpose or complexity of the financial operations involved.
