We account for these jointly owned assets by recording property, plant and equipment for our percentage of ownership interest. Various agreements provide the authority for construction of capital improvements and for the operating costs associated with the substations and lines. Generally, each party is responsible for the capital, operation and maintenance, and other costs of these jointly owned facilities based upon each participant’s undivided ownership interest. Our MISO Regulated Operating Subsidiaries’ participating share of expenses associated with these jointly held assets are primarily recorded within operating and maintenance expense on our consolidated statement of operations. </div> <div style="margin-top: 6pt;

Should include a table showing separately for each interest the amount of plant in service, the accumulated provision for depreciation (if available), the amount of plant under construction, and the proportionate share. The amounts presented may be further subdivided to show amounts applicable to plant subcategories (for example, production, transmission, distribution). Should include statements that the amounts represent the utility's share in each joint plant and that it must provide its own financing. Information concerning two or more generating plants on the same site may be combined. Should state that the utility's share of direct expenses of the joint plants is included in the corresponding operating expenses on its income statement (for example, fuel, maintenance of plant, other operating expense). If the share of direct expenses is charged to purchased power then should disclose the amount so charged and the proportionate amounts charged to specific operating expenses on the records maintained for the joint plants.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Staff Accounting Bulletin (SAB) -Number Topic 10 -Section C falsefalseJOINTLY OWNED UTILITY PLANT/COORDINATED SERVICES12Jointly Owned Utility Plant/Coordinated ServicesUnKnownUnKnownUnKnownUnKnownfalsetrue
