Public Service Building During a significant rain event in May 2020, an underground steam tunnel in downtown Milwaukee flooded and steam vented into WE’s Public Service Building. The damage to the building from the flooding and steam was extensive and will require significant repairs and restorations. As of December 31, 2020, WE had incurred $35.2 million of costs related to these repairs and restorations. WE received $20.0 million of insurance proceeds to cover a portion of these costs and $2.7 million was recorded as a receivable for future insurance recoveries. The remaining $12.5 million of costs were included in other operation and maintenance expense. We anticipate that the majority of future capital expenditures required to restore the Public Service Building will either be covered by insurance or recovery will be requested from the PSCW. As such, we do not currently expect a significant impact to our future results of operations, and although we may experience differences between periods in the timing of cash flows, we also do not currently expect a significant impact to our long-term cash flows from this event.
