GENERAL INSTRUCTIONS
Section 4 - Combined Gas and Electric Companies

(a) Balance Sheet Accounts. Companies operating more than one department, such as gas and electric, are not required to keep separate balance sheet accounts for each department, but separate accounts must be kept for each class of utility property to the extent provided in the texts and instructions pertaining to plant and equipment accounts and other items as specifically required in the texts of the accounts.

(b) Property Accounts. A clear division (so far as possible) must be maintained for each utility department. Each class of accounts shall include all expenditures that can be definitely and properly assigned thereto.

In case the accounts of the company do not definitely show the cost of the property to be assigned to the utility departments operated, the property may be divided on an estimated basis.

In the numbering system used herein, as shown below, certain groupings are denoted by the prefixes E and G to provide required segregation of these accounts although a utility may adopt such other prefix or suffix as may be deemed necessary.
