Avista Corp.&#8217;s investigation has determined that the primary cause of the fires in its region was extreme high winds, a weather event that triggered wildfires and affected electric utilities throughout the Pacific Northwest. To date, the Company has not found any evidence that the fires were caused by any deficiencies in its equipment, maintenance activities or vegetation management practices. However, the Company has become aware of instances where, during the course of the storm, otherwise healthy trees and limbs, located in areas outside its maintenance right-of-way, broke under the extraordinary wind conditions and caused damage to its energy delivery system at or near what is believed to be the area of origin of a wildfire. Those instances include what has been referred to as:&#160;the Babb Road fire (near Malden and Pine City, Washington)&#59; the Christensen Road fire (near Airway Heights, Washington)&#59; and the Mile Marker 49 fire (near Orofino, Idaho).&#160;Parallel investigations by the Department of Natural Resources are ongoing, and Avista Corp. is fully cooperating with these efforts.&#160;&#160;&#160; </p>
