For the housing accommodations in each project operated by a housing corporation, the Illinois Housing Development Authority shall prescribe and may alter a schedule of maximum rents. A hearing for the purpose of prescribing or altering such rents may be had upon motion of the Illinois Housing Development Authority or upon application of any party in interest. An order prescribing or altering schedules of rents shall be made only after public hearing, ten days' notice of the time and place of which shall be published in a newspaper of general circulation in the city, town or village in which the premises are located. Such rents shall be calculated to provide, together with all other income of the housing corporation, an income to the housing corporation sufficient to meet the following charges:
(a) All fixed charges, and all operating and maintenance charges and expenses, including taxes, special assessments, insurance premiums, fees paid to the Illinois Housing Development Authority for the amortization of indebtedness secured by mortgage upon the project, reserves and corporate expenses essential to the operation and management of the project, and depreciation reserves, if any.(b) A dividend at a rate not exceeding the maximum permitted by this Act upon the capital stock of the housing corporation allocated by the Illinois Housing Development Authority to the specific project. The amount of capital so allocated shall in no case exceed the final cost of the project plus the working capital authorized by the Illinois Housing Development Authority, after deducting the obligations of the corporation secured by liens upon the project and certificates of indebtedness or other securities, the proceeds of which have been applied to the cost of the project.(c) Such amounts as may be approved by the Illinois Housing Development Authority as a reserve for the retirement of the securities and obligations of the corporation not secured by mortgage.(d) Amounts approved by the Illinois Housing Development Authority to be carried to surplus. Such surplus shall not exceed 25 per centum of the outstanding capital stock, securities and obligations of the housing corporation not secured by mortgage, allocated by the Illinois Housing Development Authority to the project aforesaid. In cases where tenants of the project own stock, securities or obligations of the corporation not secured by mortgage, the Illinois Housing Development Authority may establish regulations for the creation of a reserve for the purchase, at not more than their face value plus accrued interest or dividends, of such securities or obligations held by tenants ceasing to be occupants of the premises, and securities or obligations so purchased may be resold by the corporation.
