Peer Group Issuers, Footnote [Text Block] | The Peer Group for which Total Shareholder Return is provided in column (g) for each listed fiscal year consists of the constituent companies in the S&P MidCap 400 Index listed as our compensation benchmarking peer group in the Compensation Discussion & Analysis specific for that fiscal year. As further described in the “Use of Market Data” section of our Compensation Discussion and Analysis for this year and prior years, the 2020 peer group reflected the market for WillScot prior to the merger with Mobile Mini, the 2021 peer group was changed to reflect the size and complexity of WillScot Mobile Mini as a combined entity, and the 2022 peer group reflects changes to better align with complexities of our business, including our long-duration lease portfolios, focus on developing turnkey space and storage solutions, use of long-lived assets, and the continued scale and growth of our business. Note, Ecolab was erroneously listed in the peer group for 2022 in our proxy statement dated April 19, 2022 and correctly excluded in this year’s filing. 2020 2021 2022 Air Lease Corporation ABM Industries Incorporated Air Lease Corporation Aircastle Limited Air Lease Corporation Americold Realty Trust, Inc.

Adjustment to Non-PEO NEO Compensation Footnote [Text Block] | The following amounts were deducted from / added to Summary Compensation Table (SCT) total compensation in accordance with the SEC-mandated adjustments to calculate Compensation Actually Paid (CAP) to our principal executive officer (PEO) and average CAP to our non-PEO named executive officers.

The rules prescribed by the SEC did not specify how compensation actually paid should reflect the incremental fair value expense recorded in connection with the modification and reported in the “Stock Awards” column. As compensation actually paid is meant to track the value of an equity award over the course of its vesting period, we are not adding any additional fair value when calculating the “Change in Fair Value as of Vesting Date of Stock Awards Granted in Prior Fiscal Years For Which Applicable Vesting Conditions Were Satisfied During Fiscal Year” as we believe this methodology best reflects the value of the award to Mr. Williams. | ||
