Awards granted during a given fiscal year are valued in the actual compensation paid at their fair value at the end of the fiscal year. Dividends paid/accrued are included in actual compensation paid if dividends are not reflected in the fair value of the awards. We computed fair value of these awards in accordance with FASB ASC Topic 718. We base the fair value of ROIC and ESG performance share awards on the target number of unvested units outstanding, the share price and the probable outcome of each performance condition which varies from 0 to 200%. We base the fair value of RSU awards on the number of unvested units outstanding at the share price. We base the fair value of TSR on the target number of unvested units outstanding and the valuation of each award based on a Monte Carlo simulation, using the following range of assumptions: ​ ​ Valuation Date ​ ​ 09/30/19 ​ ​ ​ 09/30/20 ​ ​ ​ 09/30/21 ​ ​ ​ 12/31/21 ​ ​ ​ 12/31/22 ​ ​ Grant Date ​ ​ 11/20/17 ​ ​ 11/19/18 ​ ​ ​ 11/19/18 ​ ​ 11/18/19 ​ ​ ​ 11/18/19 ​ ​ 11/16/20 ​ ​ ​ 11/18/19 ​ ​ 11/16/20 ​ ​ ​ 11/16/20 ​ ​ 02/21/22 ​ ​ Assumptions: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Expected volatility - Oshkosh ​ ​ ​ ​ 38.53 % ​ ​ ​ ​ ​ 33.10 % ​ ​ ​ ​ ​ ​ 48.61 % ​ ​ ​ ​ ​ 43.88 % ​ ​ ​ ​ ​ ​ 33.21 % ​ ​ ​ ​ ​ 41.60 % ​ ​ ​ ​ ​ ​ 27.36 % ​ ​ ​ ​ ​ 36.74 % ​ ​ ​ ​ ​ ​ 33.16 % ​ ​ ​ ​ ​ 31.68 % ​ ​ ​ Expected volatility - Peer Group ​ ​ ​ ​ 30.44 % ​ ​ ​ ​ ​ 28.96 % ​ ​ ​ ​ ​ ​ 58.19 % ​ ​ ​ ​ ​ 48.62 % ​ ​ ​ ​ ​ ​ 34.38 % ​ ​ ​ ​ ​ 48.75 % ​ ​ ​ ​ ​ ​ 29.06 % ​ ​ ​ ​ ​ 40.33 % ​ ​ ​ ​ ​ ​ 37.56 % ​ ​ ​ ​ ​ 35.19 % ​ ​ ​ Average correlation ​ ​ ​ ​ 0.5515 ​ ​ ​ ​ ​ 0.5151 ​ ​ ​ ​ ​ ​ 0.7053 ​ ​ ​ ​ ​ 0.6826 ​ ​ ​ ​ ​ ​ 0.5325 ​ ​ ​ ​ ​ 0.6733 ​ ​ ​ ​ ​ ​ 0.5407 ​ ​ ​ ​ ​ 0.6084 ​ ​ ​ ​ ​ ​ 0.6654 ​ ​ ​ ​ ​ 0.6066 ​ ​ ​ Risk-free interest rate ​ ​ ​ ​ 1.74 % ​ ​ ​ ​ ​ 1.62 % ​ ​ ​ ​ ​ ​ 0.12 % ​ ​ ​ ​ ​ 0.13 % ​ ​ ​ ​ ​ ​ 0.09 % ​ ​ ​ ​ ​ 0.28 % ​ ​ ​ ​ ​ ​ 0.29 % ​ ​ ​ ​ ​ 0.64 % ​ ​ ​ ​ ​ ​ 4.69 % ​ ​ ​ ​ ​ 4.36 % ​ ​ (4) The following NEOs were included in fiscal 2020: Mr. John Bryant, Mr. Nerenhausen, Mr. Pack, Mr. Pfeifer, Mr. David Sagehorn, and Mr. Robert Sims.

Adjusted operating income for fiscal 2022 excludes losses on the liquidation of foreign entities ($4.6 million), impairment charges ($7.7 million), earnings of Maxi-Metal ($0.5 million) and adds back a charge to account for inventories on a Last-In, First-Out (LIFO) basis ($57.9 million). Adjusted operating income for the Transition Period adds back a charge to account for inventories on a LIFO basis ($23.6 million). Adjusted operating income for fiscal 2021 excludes restructuring-related charges ($11.3 million), losses associated with Pratt Miller ($3.9 million) and adds back a charge to account for inventories on a LIFO basis ($47.4 million). Adjusted operating income for fiscal 2020 excludes restructuring-related charges ($22.4 million), a gain on the sale of a business ($3.1 million), insurance proceeds ($12.3 million) and a benefit to account for inventories on a LIFO basis ($3.9 million).

Adjusted operating income for fiscal 2022 excludes losses on the liquidation of foreign entities ($4.6 million), impairment charges ($7.7 million), earnings of Maxi-Metal ($0.5 million) and adds back a charge to account for inventories on a Last-In, First-Out (LIFO) basis ($57.9 million).
