Section 16.4 Accounts.
   Separate accounts shall be kept for each public utility owned or operated by the City, distinct from other City accounts, and in such manner as to show the true and complete financial result of such City ownership or operation, or both, including all assets, liabilities, revenues, and expenses. They shall show, as nearly as possible, the value of any service furnished to or rendered by any such public utility by or to any other City department. The Council shall annually cause to be made a report showing the financial results of such City ownership or operation, or both, which report shall give for each utility, the information specified in this section, and such further information as the Council shall deem expedient. Such report shall be on file in the office of the Clerk for public inspection.
