Summary of Significant Accounting Policies	Mar. 31, 2018
Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Organization and Nature of Operations WillScot Corporation (“WSC” or along with its subsidiaries, the “Company”), is a leading provider of modular space and portable storage solutions in the United States (“US”), Canada and Mexico. The Company, whose securities are listed on the Nasdaq Capital Market, serves as the holding company for the Williams Scotsman family of companies. All of the Company’s assets and operations are owned through Williams Scotsman Holdings Corp. (“WS Holdings”). The Company operates and owns 90% of WS Holdings, and an affiliate of TDR Capital LLP (“TDR Capital”) owns the remaining 10%. The Company was originally incorporated on June 26, 2015 under the name Double Eagle Acquisition Corporation (“Double Eagle”) as a Cayman Islands exempt, special purpose acquisition company, for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses. On November 29, 2017, the Company, through its subsidiary, WS Holdings, acquired all of the equity interest of Williams Scotsman International, Inc. (“WSII”), from Algeco Scotsman Global S.à r.l., (together with its subsidiaries, the “Algeco Group”). The Algeco Group is majority owned by an investment fund managed by TDR Capital. As part of the transaction (the “Business Combination”), the Company redomesticated and changed its name to WillScot Corporation. For further information on the organization of the Company, refer to the consolidated financial statements and notes included in our Annual Report on Form 10-K for the year ended December 31, 2017. WSII engages in the leasing and sale of mobile offices, modular buildings and storage products and their delivery and installation throughout North America. WSII also provided full-service remote workforce accommodation solutions prior to the Business Combination. The remote accommodations business, which consisted of Target Logistics Management LLC (“Target Logistics”) and its subsidiaries and Chard Camp Catering Services (“Chard,” and together with Target Logistics, the “Remote Accommodations Business”), was transferred to another Algeco Group entity prior to consummation of the Business Combination and is presented as discontinued operations in the condensed consolidated financial statements. Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and do not include all the information and notes required by accounting principles generally accepted in the United States (“GAAP”) for complete financial statements. The accompanying condensed consolidated financial statements contain all adjustments, which are of a normal and recurring nature, necessary to present fairly the financial position and the results of operations for the interim periods presented. The results of consolidated operations for the three months ended March 31, 2018 are not necessarily indicative of the results to be expected for the full year. For further information, refer to the consolidated financial statements and notes included in our Annual Report on Form 10-K for the year ended December 31, 2017. Principles of Consolidation The condensed consolidated financial statements comprise the financial statements of the Company and its subsidiaries that it controls due to ownership of a majority voting interest. Subsidiaries are fully consolidated from the date of acquisition, being the date on which the Company obtains control, and continue to be consolidated until the date when such control ceases. The financial statements of the subsidiaries are prepared for the same reporting period as the Company. All intercompany balances and transactions are eliminated.The Business Combination was accounted for as a reverse recapitalization (the "Recapitalization Transaction") in accordance with Accounting Standard Codification (“ASC”) 805, Business Combinations. Although WSC was the indirect acquirer of WSII for legal purposes, WSII was considered the acquirer for accounting and financial reporting purposes. As a result of WSII being the accounting acquirer, the financial reports filed with the SEC by the Company subsequent to the Business Combination are prepared “as if” WSII is the predecessor and legal successor to the Company. The historical operations of WSII are deemed to be those of the Company. Thus, the financial statements included in this report reflect (i) the historical operating results of WSII prior to the Business Combination; (ii) the combined results of the Company and WSII following the Business Combination on November 29, 2017; (iii) the assets and liabilities of WSII at their historical cost; and (iv) WSC’s equity structure for all periods presented. The recapitalization of the number of shares of common stock attributable to the purchase of WSII in connection with the Business Combination is reflected retroactively to the earliest period presented and will be utilized for calculating earnings per share in all prior periods presented. No step-up basis of intangible assets or goodwill was recorded in the Business Combination transaction consistent with the treatment of the transaction as a reverse capitalization of WSII. WSII’s Remote Accommodations Business was transferred to other Algeco Group members on November 28, 2017 in a transaction under common control and was not included as part of the Business Combination. The operating results of the Remote Accommodations Business, net of tax, for the three months ended March 31, 2017 have been reported as discontinued operations in the condensed consolidated financial statements. Recently Issued and Adopted Accounting Standards The Company qualifies as an emerging growth company (“EGC”) as defined under the Jumpstart Our Business Startups Act (the “JOBS Act”). Using exemptions provided under the JOBS Act provided to EGCs, the Company has elected to defer compliance with new or revised financial accounting standards until a company that is not an issuer (as defined under section 2(a) of the Sarbanes-Oxley Act of 2002) is required to comply with such standards. As such, compliance dates included below pertain to non-issuers, and as permitted, early adoption dates for non-issuers are indicated. Recently Issued Accounting Standards In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers (Topic 606), which prescribes a single comprehensive model for entities to use in the accounting for revenue arising from contracts with customers. The new guidance will supersede virtually all existing revenue guidance under GAAP and is effective for annual reporting periods beginning after December 15, 2018. Early adoption for non-public entities is permitted starting with annual reporting periods beginning after December 15, 2016. The core principle contemplated by this new standard is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount reflecting the consideration to which the entity expects to be entitled in exchange for those goods or services. New disclosures about the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers are also required. In April and May 2016, the FASB also issued clarifying updates to the new standard specifically to address certain core principles including the identification of performance obligations, licensing guidance, the assessment of the collectability criterion, the presentation of taxes collected from customers, non-cash considerations, contract modifications and completed contracts at transition. The Company is currently evaluating the impact that the updated guidance will have on the Company’s financial statements and related disclosures. As part of the evaluation process, the Company is holding regular meetings with key stakeholders from across the organization to discuss the impact of the standard on its existing contracts. The Company is utilizing a bottom-up approach to analyze the impact of the standard on its portfolio of contracts by reviewing the Company’s current accounting policies and practices to identify potential differences that would result from applying the requirements of the new standard to the Company’s existing revenue contracts. As part of its implementation project, the Company has prepared analysis with respect to revenue stream scoping, performed contract reviews, developed a preliminary gap analysis, and begun to address revised disclosure requirements. The Company is in the process of assessing the impact of the Acton and Tyson acquisitions on the work previously completed as part of the implementation project. The Company is still completing this evaluation and has not yet determined the impact on its financial statements. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). This guidance revises existing practice related to accounting for leases under ASC Topic 840, Leases (“ASC 840”) for both lessees and lessors. The new guidance requires lessees to recognize a right-of-use asset and a lease liability for virtually all of their leases (other than leases that meet the definition of a short-term lease). The lease liability will be equal to the present value of lease payments and the right-of-use asset will be based on the lease liability, subject to adjustment such as for initial direct costs. For income statement purposes, the new standard retains a dual model similar to ASC 840, requiring leases to be classified as either operating or finance. Operating leases will result in straight-line expense (similar to current accounting by lessees for operating leases under ASC 840) while finance leases will result in a front-loaded expense pattern (similar to current accounting by lessees for capital leases under ASC 840). While the new standard maintains similar accounting for lessors as under ASC 840, the new standard reflects updates to, among other things, align with certain changes to the lessee model. The new standard will be effective for fiscal years beginning after December 15, 2019, and interim periods within fiscal years beginning after December 15, 2020. Early adoption is permitted for all entities. The Company is currently evaluating the impact of the pronouncement on its consolidated financial statements. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230) - Classification of Certain Cash Receipts and Cash Payments. The standard is intended to eliminate diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The new standard will be effective for the fiscal years beginning after December 15, 2018. Early adoption is permitted for all entities. The Company does not believe the pronouncement will have a material impact on its consolidated financial statements. In December 2016, the FASB issued ASU 2016-19, Technical Corrections and Improvements, stating that software licenses should be accounted for as the acquisition of an intangible asset and of a liability incurred. This new standard will be effective for annual periods beginning after December 15, 2017, and interim periods in annual periods beginning after December 15, 2018. The Company plans to adopt this pronouncement for the annual period ending December 31, 2018 and is still evaluating the potential impact from adoption of this new accounting pronouncement on its financial statements. In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805) - Clarifying the Definition of a Business. This new standard will be effective for annual periods beginning after December 15, 2018. This guidance changes the definition of a business to assist entities in evaluating when a set of transferred assets and activities constitutes a business. The guidance requires an entity to evaluate if substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets; if so, the set of transferred assets and activities is not a business. The guidance also requires a business to include at least one substantive process and narrows the definition of outputs by more closely aligning it with how outputs are described in ASC 606, Revenue from Contracts with Customers. Early adoption is permitted for all entities. The Company is still evaluating the potential impact from adoption of this new accounting pronouncement on its financial statements. Recently Adopted Accounting Standards From time to time, new accounting pronouncements are issued by the FASB or other standard setting bodies that are adopted by the Company as of the specified effective date. In October 2016, the FASB issued ASU 2016-16, Income Taxes (Topic 740) - Intra-Entity Transfers of Assets Other Than Inventory. The standard is intended to improve the accounting for the income tax consequences of intra-entity transfers of assets other than inventory. The new standard will be effective for annual reporting periods beginning after December 15, 2018. Early adoption is permitted for all entities as long as entities adopt at the beginning of an annual reporting period. The Company elected to early adopt this standard effective January 1, 2018. The pronouncement had no material impact on the Company’s condensed consolidated financial statements. During December 2017, shortly after the Tax Cuts and Jobs Act (the “Tax Act”) was enacted, the Securities and Exchange Commission (“SEC”) issued Staff Accounting Bulletin No. 118, Income Tax Accounting Implications of the Tax Cuts and Jobs Act (“SAB 118”) which provides guidance on accounting for the Tax Act’s impact. SAB 118 provides a measurement period, which in no case should extend beyond one year from the Tax Act enactment date, during which a company acting in good faith may complete the accounting for the impacts of the Tax Act under ASC Topic 740. Per SAB 118, companies must reflect the income tax effects of the Tax Act in the reporting period in which the accounting under ASC Topic 740 is complete. To the extent the accounting for certain income tax effects of the Tax Act is incomplete, companies can determine a reasonable estimate for those effects and record a provisional estimate in the financial statements in the first reporting period in which a reasonable estimate can be determined. If a company cannot determine a provisional estimate to be included in the financial statements, it should continue to apply ASC 740 based on the provisions of the tax laws that were in effect immediately prior to the Tax Act being enacted. If a company is unable to provide a reasonable estimate of the impacts of the Tax Act in a reporting period, a provisional amount must be recorded in the first reporting period in which a reasonable estimate can be determined. As a result of the Tax Act, the Company remeasured its net deferred tax liabilities and recognized a provisional net benefit of $28.1 million. In addition, based on information currently available, the Company recorded a provisional income tax expense of $2.4 million related to the deemed repatriation of foreign earnings. The Company recorded a minor adjustment to the provisional amounts recorded in its financial statements for the year ended December 31, 2017 (see Note 9) and continues to evaluate the provisions of the Tax Act including guidance from the Department of Treasury and Internal Revenue Service. Additionally, the Company expects to file its US tax return for 2017 during the fourth quarter of 2018 and any changes to the estimates used to the final tax positions for temporary differences, earnings and profits will result in adjustments of the remeasurement amounts for the Tax Act recorded as of December 31, 2017. The Company continues to evaluate the impact of the Global Low Taxed Intangible Income (“GILTI”) provision of the Tax Act. The Company is required to make an accounting policy election of either (1) treating GILTI as a current period expense when incurred or (2) factoring such amounts into the Company’s measurement of its deferred taxes. The Company has not completed its analysis and has not made a determination of its accounting policy for GILTI. In February 2018, the FASB issued ASU 2018-02, Income Statement-Reporting Comprehensive Income (Topic 220) - Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, to address a specific consequence of the Tax Act by allowing a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Act’s reduction of the US federal corporate income tax rate. ASU 2018-02 is effective for all entities for fiscal years beginning after December 15, 2018, with early adoption permitted, and is to be applied either in the period of adoption or retrospectively to each period in which the effect of the change in the US federal corporate income tax rate in the Tax Act is recognized. The Company elected to early adopt this standard and record an adjustment in the period of adoption (i.e. as of January 1, 2018) of $2.5 million from accumulated other comprehensive loss to accumulated deficit that related to stranded tax effects related to currency translation adjustments. ASU 2018-02 also requires issuers to disclose its policy for releasing income tax effects from accumulated other comprehensive income. The Company’s accounting policy is to release income tax effects with respect to currency translation matters on a portfolio basis.

Acquisitions

Tyson Onsite Acquisition

On January 3, 2018, the Company acquired all of the issued and outstanding membership interests of Onsite Space LLC (d/b/a Tyson Onsite (“Tyson”)). Tyson provided modular space rental services in the Midwest, primarily in Indiana, Illinois and Missouri. The Company expects to realize synergies and cost savings related to this acquisition as a result of purchasing and procurement economies of scale and general and administrative expense savings, particularly with respect to the consolidation of corporate related functions and elimination of redundancies. The acquisition date fair value of the consideration transferred consisted of $24.0 million in cash consideration, net of cash acquired. The transaction was fully funded by borrowings under the Asset-Backed Lending (“ABL”) Facility.

As part of the acquisition, $0.2 million of cash was acquired, $20.4 million was attributed to rental fleet and $3.4 million was attributed to goodwill. All goodwill is expected to be deductible for tax purposes. As a result of the timing of the transaction, the purchase price allocation for the rental fleet acquired is based on a preliminary valuation and is subject to change as the Company obtains additional information during the acquisition measurement period. Increases or decreases in the estimated fair values of the net assets acquired may impact the Company’s statements of operations in future periods. The Company expects that the preliminary values assigned to the rental fleet and goodwill will be finalized during the one-year measurement period following the acquisition date.

Tyson results were immaterial to the condensed consolidated statements of operations for the three months ended March 31, 2018 and as a result, the Company is not presenting pro-forma information.

Acton Acquisition

On December 20, 2017, WSII acquired 100% of the issued and outstanding ownership interests of Acton Mobile Holdings LLC (“Acton”) for a cash purchase price of $237.1 million, subject to certain adjustments. Acton owns all of the issued and outstanding membership interests of New Acton Mobile Industries, which provided modular space and portable storage rental services across the US. WSII funded the acquisition with cash on hand and borrowings under the ABL Facility. The Company incurred $2.6 million in integration fees associated the Acton acquisition within selling, general, and administrative expenses (“SG&A”) for the three months ended March 31, 2018.

As of March 31, 2018, the Company recorded an adjustment to the Acton opening balance sheet which increased accrued liabilities by $1.0 million due to further evaluation of unindemnified liabilities. This increase resulted in an equal increase in goodwill as detailed in Note 6. As a result of the timing of the transaction, the purchase price allocations for the rental equipment, intangible assets, property, plant and equipment, deferred tax assets, and other accrued tax liabilities acquired and assumed are based on preliminary valuations and are subject to change as the Company obtains additional information during the acquisition measurement period. Increases or decreases in the estimated fair values of the net assets acquired may impact the Company’s statements of operations in future periods. The Company expects that the preliminary values assigned to the rental equipment, intangible assets, property, plant and equipment, deferred tax assets, and other accrued tax liabilities will be finalized during the one-year measurement period following the acquisition date.

The pro-forma information below has been prepared using the purchase method of accounting, giving effect to the Acton acquisition as if it had been completed on January 1, 2017 (the “pro-forma acquisition date”). The pro-forma information is not necessarily indicative of the Company’s results of operations had the acquisition been completed on the above date, nor is it necessarily indicative of the Company’s future results. The pro-forma information does not reflect any cost savings from operating efficiencies or synergies that could result from the acquisition, and also does not reflect additional revenue opportunities following the acquisition.

The table below presents unaudited pro-forma consolidated statements of operations information as if Acton had been included in the Company’s consolidated results for the three months ended March 31, 2017:

Discontinued Operations and Disposal Groups [Abstract]

Discontinued Operations

WSII’s Remote Accommodations Business was transferred to another entity included in the Algeco Group prior to the Business Combination. WSII does not expect to have continuing involvement in the Remote Accommodations Business going forward. Historically, the Remote Accommodations Business leased rental equipment from WSII. After the Business Combination, several lease agreements for rental equipment still exist between the Company and Target Logistics. The lease revenue associated with these agreements is disclosed in Note 16.

As a result of the transactions discussed above, the Remote Accommodations segment has been reported as discontinued operations in the condensed consolidated statements of operations for all periods presented.

As there was no carrying value of debt outstanding on the Canadian ABL Facility as of December 31, 2017, $1.8 million of debt issuance costs related to that facility are included in other non-current assets on the condensed consolidated balance sheet.

ABL Facilities

Former Algeco Group Revolver

Prior to the Business Combination, WSII depended on the Algeco Group for financing, which centrally managed all treasury and cash management. In October 2012, the Algeco Group entered into a multicurrency asset-based revolving credit facility (the “Algeco Group Revolver”), which had a maximum aggregate availability of the equivalent of $1.355 billion. The maximum borrowing availability to WSII in United States dollars and Canadian dollars (“CAD”) was $760.0 million and $175.0 million, respectively.

Interest expense of $6.2 million related to the Algeco Group Revolver was included in interest expense for the three months ended March 31, 2017.

ABL Facility

On November 29, 2017, WS Holdings, WSII and certain of its subsidiaries entered into an ABL credit agreement (the “ABL Facility”) that provides a senior secured revolving credit facility in the aggregate principal amount of up to $600.0 million. The ABL Facility, which matures on May 29, 2022, consists of (i) a $530.0 million asset-backed revolving credit facility (the “US ABL Facility”) for WSII and certain of its domestic subsidiaries (the “US Borrowers”), (ii) a $70.0 million asset-based revolving credit facility (the “Canadian ABL Facility”) for Williams Scotsman of Canada, Inc. (the “Canadian Borrower,” and together with the US Borrowers, the “Borrowers”), and (iii) an accordion feature that permits the Borrowers to increase the lenders’ commitments in an aggregate amount not to exceed $300.0 million, subject to the satisfaction of customary conditions, plus any voluntary prepayments that are accompanied by permanent commitment reductions under the ABL Facility.

Borrowings under the ABL Facility, at the Borrower’s option, bear interest at an adjusted LIBOR or base rate, in each case plus an applicable margin. The applicable margin is fixed at 2.50% for LIBOR borrowings and 1.50% for base rate borrowings up until March 31, 2018. Commencing on March 31, 2018, the applicable margins are subject to one step-down of 0.25% or one step-up of 0.25%, based on excess availability levels with respect to the ABL Facility. The ABL Facility requires the payment of an annual commitment fee on the unused available borrowings of between 0.375% and 0.5% per annum. At March 31, 2018, the weighted average interest rate for borrowings under the ABL Facility was 4.35%.

Borrowing availability under the US ABL Facility and the Canadian ABL Facility is equal to the lesser of (i) with respect to US Borrowers, $530.0 million and the US Borrowing Base (defined below) (the “US Line Cap”), and (ii) with respect to the Canadian Borrower, $70.0 million and the Canadian Borrowing Base (defined below) (the “Canadian Line Cap,” together with the US Line Cap, the “Line Cap”).

The US Borrowing Base is, at any time of determination, an amount (net of reserves) equal to the sum of:


•	85% of the net book value of the US Borrowers’ eligible accounts receivable, plus


•	the lesser of (i) 95% of the net book value of the US Borrowers’ eligible rental equipment and (ii) 85% of the net orderly liquidation value of the US Borrowers’ eligible rental equipment, minus


•	customary reserves.

The Canadian Borrowing Base is, at any time of determination, an amount (net of reserves) equal to the sum of:


•	85% of the net book value of the Canadian Borrowers’ eligible accounts receivable, plus


•	the lesser of (i) 95% of the net book value of the Canadian Borrowers’ eligible rental equipment and (ii) 85% of the net orderly liquidation value of the Canadian Borrowers’ eligible rental equipment, plus


•	portions of the US Borrowing Base that have been allocated to the Canadian Borrowing Base, minus


•	customary reserves.

At March 31, 2018, the Line Cap was $600.0 million and the Borrowers had $243.8 million of available borrowing capacity under the ABL Facility, including $174.6 million under the US ABL Facility and $69.2 million under the Canadian ABL Facility. At December 31, 2017, the Line Cap was $600.0 million and the Borrowers had $281.1 million of available borrowing capacity under the ABL Facility, including $211.1 million under the US ABL Facility and $70.0 million under the Canadian ABL Facility.

Borrowing capacity under the US ABL Facility is made available for up to $60.0 million of standby letters of credit and up to $50.0 million of swingline loans, and borrowing capacity under the Canadian ABL Facility is made available for up to $30.0 million of standby letters of credit, and $25.0 million of “swingline” loans. Letters of credit and bank guarantees carried fees of 2.625% at March 31, 2018 and December 31, 2017, respectively. The Company had issued $8.9 million of standby letters of credit under the ABL Facility at March 31, 2018 and December 31, 2017.

The ABL Facility requires the Borrowers to maintain a (i) minimum fixed charge coverage ratio of 1.00:1.00 and (ii) maximum total net leverage ratio of 5.50:1.00, in each case, at any time when the excess availability under the ABL Facility is less than the greater of (a) $50.0 million and (b) an amount equal to 10% of the Line Cap.

The ABL Facility also contains a number of customary negative covenants. Such covenants, among other things, may limit or restrict the ability of each of the Borrowers, their restricted subsidiaries, and where applicable, WS Holdings, to: incur additional indebtedness, issue disqualified stock and make guarantees; incur liens; engage in mergers or consolidations or fundamental changes; sell assets; pay dividends and repurchase capital stock; make investments, loans and advances, including acquisitions; amend organizational documents and master lease documents; enter into certain agreements that would restrict the ability to pay dividends or incur liens on assets; repay certain junior indebtedness; enter into sale and leaseback transactions; and change the conduct of its business.

The aforementioned restrictions are subject to certain exceptions including (i) the ability to incur additional indebtedness, liens, investments, dividends, and prepayments of junior indebtedness subject, in each case, to compliance with certain financial metrics and certain other conditions and (ii) a number of other traditional exceptions that grant the Borrowers continued flexibility to operate and develop their businesses. The ABL Facility also contains customary representations and warranties, affirmative covenants and events of default. The Company is in compliance with these covenants and restrictions as of March 31, 2018.

The Company had $347.3 million and $310.0 million in outstanding principal under the ABL Facility at March 31, 2018 and December 31, 2017, respectively. Debt issuance costs and discounts of $12.7 million and $12.7 million are included in the carrying value of debt at March 31, 2018 and December 31, 2017, respectively.

Senior Secured Notes

WSII has $300.0 million aggregate principal amount of 7.875% senior secured notes due December 15, 2022 (the “Notes”) under an indenture dated November 29, 2017, which was entered into by and among WSII, the guarantors named therein, and Deutsche Bank Trust Company Americas, as trustee and as collateral agent. Interest is payable semi-annually on June 15 and December 15 beginning June 15, 2018.

Before December 15, 2019, WSII may redeem the Notes at a redemption price equal to 100% of the principal amount, plus a customary make whole premium for the Notes being redeemed, plus accrued and unpaid interest, if any, to but not including the redemption date.

The customary make whole premium, with respect to any Note on any applicable redemption date, as calculated by the Company, is the greater of (i) 100% of the then outstanding principal amount of the Note; and (ii) the excess of (a) the present value at such redemption date of (i) the redemption price set on or after December 15, 2019 plus (ii) all required interest payments due on the Note through December 15, 2019, excluding accrued but unpaid interest to the redemption date, in each case, computed using a discount rate equal to the Treasury Rate as of such redemption date plus 50 basis points; over (b) the then outstanding principal amount of the Note.

Before December 15, 2019, WSII may redeem up to 40% of the aggregate principal amount of the Notes at a price equal to 107.875% of the principal amount of the Notes being redeemed, plus accrued and unpaid interest, if any, to but not including the redemption date with the net proceeds of certain equity offerings. At any time prior to November 29, 2019, WSII may also redeem up to 10% of the aggregate principal amount of the Notes at a redemption price equal to 103% of the principal amount of the Notes being redeemed during each twelve-month period commencing with the closing date, plus accrued and unpaid interest, if any, to but not including the redemption date. If WSII undergoes a change of control or sells certain of its assets, WSII may be required to offer to repurchase the Notes.

On or after December 15, 2019, WSII, at its option, may redeem the Notes, in whole or in part, at the redemption prices expressed as percentages of principal amount set forth below, plus accrued and unpaid interest to, but not including, the applicable redemption date (subject to the right of Note holders on the relevant record date to receive interest due on an interest payment date falling on or prior to the redemption date), if redeemed during the twelve month period beginning on December 15 of each of the years set forth below:



Year	Redemption Price
2019	103.938	%
2020	101.969	%
2021 and thereafter	100.000	%

The Notes contain certain negative covenants, including limitations that may restrict WSII’s ability and the ability of certain of its subsidiaries, to directly or indirectly, create additional financial obligations. With certain specified exceptions, these negative covenants prohibit WSII and certain of its subsidiaries from: creating or incurring additional debt; paying dividends or making any other distributions with respect to its capital stock; making loans or advances to WSC or any restricted subsidiary of WSII; selling, leasing or transferring any of its property or assets to WSC or any restricted subsidiary of WSII; directly or indirectly creating, incurring or assuming any lien of any kind securing debt on the collateral; or entering into any sale and leaseback transaction.

The aforementioned restrictions are subject to certain exceptions including (i) the ability to incur additional indebtedness, liens, investments, dividends and distributions, and prepayments of junior indebtedness subject, in each case, to compliance with certain financial metrics and certain other conditions and (ii) a number of other traditional exceptions that grant the US Borrowers continued flexibility to operate and develop their businesses. The Company is in compliance with these covenants and restrictions as of March 31, 2018 and December 31, 2017.

Unamortized debt issuance costs pertaining to the Notes was $8.9 million and $9.3 million as of March 31, 2018 and December 31, 2017, respectively.

Capital Lease and Other Financing Obligations

The Company’s capital lease and financing obligations primarily consisted of $38.3 million and $38.5 million under sale-leaseback transactions and $0.2 million and $0.2 million of capital leases at March 31, 2018 and December 31, 2017, respectively. The Company’s capital lease and financing obligations are presented net of $1.7 million and $1.8 million of debt issuance costs at March 31, 2018 and December 31, 2017, respectively. The Company’s capital leases primarily relate to real estate, equipment and vehicles and have interest rates ranging from 1.2% to 11.9%.

The Company has entered into several arrangements in which it has sold branch locations and simultaneously leased the associated properties back from the various purchasers. Due to the terms of the lease agreements, these transactions are treated as financing arrangements. These transactions contain non-recourse financing which is a form of continuing involvement and precludes the use of sale-lease back accounting. The terms of the financing arrangements range from approximately eighteen months to ten years. The interest rates implicit in these financing arrangements is approximately 8.0%.

Notes Due To and From Affiliates

Prior to the Business Combination, the Algeco Group distributed borrowings from its third party notes to entities within the Algeco Group, including WSII, through intercompany loans. WSII previously recorded these intercompany loans as notes due to affiliates with maturity dates of June 30, 2018 and October 15, 2019.

Interest expense of $14.7 million associated with these notes due to affiliates is reflected in interest expense in the consolidated statement of operations for the three months ended March 31, 2017. Interest on the notes due to affiliates was payable on a semi-annual basis.

Conversely, WSII also distributed borrowings to other entities within the Algeco Group through intercompany loans, and earned interest income on the principal. For the three months ended March 31, 2017, the Company recognized $2.6 million of interest income related to the loans.

In conjunction with the Business Combination, all notes due to and from affiliates were settled, and there is no related interest expense or interest income related to the notes due to or from affiliates for the three months ended March 31, 2018.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company recorded income tax benefit of approximately $0.4 million and $4.9 million for the three months ended March 31, 2018 and 2017, respectively. The Company’s effective tax rate for the three months ended March 31, 2018 and 2017 was 5.8% and 25.8%, respectively. The Company’s annual effective tax rate used to determine the tax benefit for the quarter of approximately 1.0% is substantially lower than the US statutory rate of 21.0% due to: (1) mix of earnings between tax paying components, notably forecasted losses in Canada which result in higher tax benefit due to a higher statutory tax rate, and (2) reduction to the deferred tax liability established for the book over tax basis difference for our investment in our Canadian subsidiary. Due to the foregoing, changes to our forecast of pre-tax book income and the mix of earnings between tax paying components that may occur due to changes in our business in subsequent periods may have a significant effect on our annual effective tax rate and consequently, tax expense (benefit) recorded in subsequent interim periods. In addition, the Company also recognized tax expense (benefit) for the three months ended March 31, 2018 and 2017 related to foreign currency gains and losses of $0.3 million and $0.7 million, respectively discrete to the quarter. The Company also adjusted the provisional amounts for the impacts of the Tax Act under SAB 118 reported in its financial statements for the year ended December 31, 2017, with an adjustment in the quarter due to a change in state law for a tax benefit of $0.3 million.

Fair Value Measures

Fair Value Disclosures [Abstract]

Fair Value Measures

The fair value of financial assets and liabilities are included at the amount at which the instrument could be exchanged in a current transaction between willing parties, other than in a forced or liquidation sale. The Company utilizes the suggested accounting guidance for the three levels of inputs that may be used to measure fair value:



Level 1 -	Observable inputs such as quoted prices in active markets for identical assets or liabilities;
Level 2 -	Observable inputs, other than Level 1 inputs in active markets, that are observable either directly or indirectly; and
Level 3 -	Unobservable inputs for which there is little or no market data, which require the reporting entity to develop its own assumptions

The Company has assessed that the fair value of cash and short-term deposits, trade receivables, trade payables, capital lease and other financing obligations, and other current liabilities approximate their carrying amounts largely due to the short-term maturities of these instruments.

The following table shows the carrying amounts and fair values of financial assets and liabilities, including their levels in the fair value hierarchy:



	March 31, 2018										December 31, 2017
	Carrying Amount			Fair Value							Carrying Amount			Fair Value

There were no transfers of financial instruments between the three levels of the fair value hierarchy during the three months ended March 31, 2018. The fair value of the Company’s ABL Facility is primarily based upon observable market data such as market interest rates. The fair value of the Company’s Notes is based on their last trading price at the end of each period obtained from a third party.

- Definition

The entire disclosure for the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments as well as disclosures related to the fair value of non-financial assets and liabilities. Such disclosures about the financial instruments, assets, and liabilities would include: (1) the fair value of the required items together with their carrying amounts (as appropriate); (2) for items for which it is not practicable to estimate fair value, disclosure would include: (a) information pertinent to estimating fair value (including, carrying amount, effective interest rate, and maturity, and (b) the reasons why it is not practicable to estimate fair value; (3) significant concentrations of credit risk including: (a) information about the activity, region, or economic characteristics identifying a concentration, (b) the maximum amount of loss the entity is exposed to based on the gross fair value of the related item, (c) policy for requiring collateral or other security and information as to accessing such collateral or security, and (d) the nature and brief description of such collateral or security; (4) quantitative information about market risks and how such risks are managed; (5) for items measured on both a recurring and nonrecurring basis information regarding the inputs used to develop the fair value measurement; and (6) for items presented in the financial statement for which fair value measurement is elected: (a) information necessary to understand the reasons for the election, (b) discussion of the effect of fair value changes on earnings, (c) a description of [similar groups] items for which the election is made and the relation thereof to the balance sheet, the aggregate carrying value of items included in the balance sheet that are not eligible for the election; (7) all other required (as defined) and desired information.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]

Stock-Based Compensation

On November 16, 2017, the Company’s shareholders approved a long-term incentive award plan (the “Plan”). The Plan is administered by the Compensation Committee of the Company’s Board of Directors. Under the Plan, the Committee may grant an aggregate of 4,000,000 shares of Class A common stock in the form of non-qualified stock options, incentive stock options, stock appreciation rights, restricted stock awards (“RSAs”), restricted stock units (“RSUs”), performance compensation awards and stock bonus awards. Stock-based payments including the grant of stock options, RSUs, and RSAs are subject to service-based vesting requirements, and expense is recognized over the vesting period. Forfeitures are accounted for as they occur. During the three months ended March 31, 2018, 27,675 RSAs, 921,730 RSUs and 589,257 stock option awards were granted under the Plan.

Stock-based payments to employees include grants of stock options and RSUs, which are recognized in the financial statements based on their fair value.

RSUs and RSAs are valued based on the intrinsic value of the difference between the exercise price, if any, of the award and the fair market value of our common stock on the grant date. RSAs vest over a one-year period and RSUs vest over a four-year period.

Stock options vest in tranches over a period of four years and expire ten years from the grant date. The fair value of each stock option award on the grant date is estimated using the Black-Scholes option-pricing model with the following assumptions: expected dividend yield, expected stock price volatility, weighted-average risk-free interest rate and weighted-average expected term of the options. The volatility assumption used in the Black-Scholes option-pricing model is based on peer group volatility as the Company does not have a sufficient trading history as a stand-alone public company. Additionally, due to an insufficient history with respect to stock option activity and post-vesting cancellations, the expected term assumption is based on the simplified method under GAAP, which is based on the vesting period and contractual term for each tranche of awards. The mid-point between the weighted-average vesting term and the expiration date is used as the expected term under this method. The risk-free interest rate used in the Black-Scholes model is based on the implied US Treasury bill yield curve at the date of grant with a remaining term equal to the Company’s expected term assumption. The Company has never declared or paid a cash dividend on common shares.

As of March 31, 2018, none of the granted RSAs, RSUs or stock options had vested.

Segment Reporting [Abstract]

Segment Reporting

The Company historically has operated in two principal lines of business; modular leasing and sales and remote accommodations, which were managed separately. The Remote Accommodations Business was considered a single operating segment. As part of the Business Combination, the Remote Accommodations segment is no longer owned by the Company and is reported as discontinued operations in the condensed consolidated financial statements. As such, the segment was excluded from the segment information below.

Modular leasing and sales is comprised of two operating segments: US and Other North America. The US modular operating segment (“Modular - US”) consists of the the contiguous 48 states and Hawaii. The Other North America operating segment (“Modular - Other North America”) consists of Alaska, Canada and Mexico. Corporate and other includes eliminations of costs and revenue between segments and Algeco Group corporate costs not directly attributable to the underlying segments. Following the Business Combination, no additional Algeco Group corporate costs were incurred. Total assets for each reportable segment are not available because the Company utilizes a centralized approach to working capital management. Transactions between reportable segments are not significant.

The Company evaluates business segment performance on Adjusted EBITDA, which excludes certain items as shown in the reconciliation of the Company’s consolidated net loss before tax to Adjusted EBITDA below. Management believes that evaluating segment performance excluding such items is meaningful because it provides insight with respect to intrinsic operating results of the Company.

The Company also regularly evaluates gross profit by segment to assist in the assessment of its operational performance. The Company considers Adjusted EBITDA to be the more important metric because it more fully captures the business performance of the segments, inclusive of indirect costs.

Loss Per Share	3 Months Ended
Loss Per Share	Mar. 31, 2018
Earnings Per Share [Abstract]
Loss Per Share	Loss Per Share Basic loss per share (“LPS”) is calculated by dividing net loss attributable to WSC by the weighted average number of Class A common stock shares outstanding during the period. Concurrently with the Business Combination,12,425,000 of Class A shares were placed into escrow and were not entitled to vote or participate in the economic rewards available to the other Class A shareholders. On January 19, 2018, 6,212,500 shares of WSC Class A common stock were released from the escrow account. The remaining 6,212,500 shares of WSC Class A common stock in escrow are not included in the LPS calculation. Class B common shares also have no rights to dividends or distributions made by the Company and, in turn, are excluded from the LPS calculation. Diluted LPS is computed similarly to basic net loss per share, except that it includes the potential dilution that could occur if dilutive securities were exercised. Effects of potentially dilutive securities are presented only in periods in which they are dilutive. 34,750,000 Class A shares of underlying warrants outstanding were excluded from the computation of diluted earnings per share because their effect would have been anti-dilutive. Stock options, restricted stock awards, and restricted stock units representing 589,257, 921,730, and 27,675 shares of Class A common stock outstanding for the three months ended March 31, 2018, were excluded from the computation of diluted earnings per share because their effect would have been anti-dilutive.

Summary of Significant Accounting Policies (Policies)	3 Months Ended
Summary of Significant Accounting Policies (Policies)	Mar. 31, 2018
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and do not include all the information and notes required by accounting principles generally accepted in the United States (“GAAP”) for complete financial statements. The accompanying condensed consolidated financial statements contain all adjustments, which are of a normal and recurring nature, necessary to present fairly the financial position and the results of operations for the interim periods presented. The results of consolidated operations for the three months ended March 31, 2018 are not necessarily indicative of the results to be expected for the full year. For further information, refer to the consolidated financial statements and notes included in our Annual Report on Form 10-K for the year ended December 31, 2017.
Principles of Consolidation	Principles of Consolidation The condensed consolidated financial statements comprise the financial statements of the Company and its subsidiaries that it controls due to ownership of a majority voting interest. Subsidiaries are fully consolidated from the date of acquisition, being the date on which the Company obtains control, and continue to be consolidated until the date when such control ceases. The financial statements of the subsidiaries are prepared for the same reporting period as the Company. All intercompany balances and transactions are eliminated.The Business Combination was accounted for as a reverse recapitalization (the "Recapitalization Transaction") in accordance with Accounting Standard Codification (“ASC”) 805, Business Combinations. Although WSC was the indirect acquirer of WSII for legal purposes, WSII was considered the acquirer for accounting and financial reporting purposes. As a result of WSII being the accounting acquirer, the financial reports filed with the SEC by the Company subsequent to the Business Combination are prepared “as if” WSII is the predecessor and legal successor to the Company. The historical operations of WSII are deemed to be those of the Company. Thus, the financial statements included in this report reflect (i) the historical operating results of WSII prior to the Business Combination; (ii) the combined results of the Company and WSII following the Business Combination on November 29, 2017; (iii) the assets and liabilities of WSII at their historical cost; and (iv) WSC’s equity structure for all periods presented. The recapitalization of the number of shares of common stock attributable to the purchase of WSII in connection with the Business Combination is reflected retroactively to the earliest period presented and will be utilized for calculating earnings per share in all prior periods presented. No step-up basis of intangible assets or goodwill was recorded in the Business Combination transaction consistent with the treatment of the transaction as a reverse capitalization of WSII. WSII’s Remote Accommodations Business was transferred to other Algeco Group members on November 28, 2017 in a transaction under common control and was not included as part of the Business Combination. The operating results of the Remote Accommodations Business, net of tax, for the three months ended March 31, 2017 have been reported as discontinued operations in the condensed consolidated financial statements.
Recently Issued and Adopted Accounting Standards	Recently Issued Accounting Standards In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers (Topic 606), which prescribes a single comprehensive model for entities to use in the accounting for revenue arising from contracts with customers. The new guidance will supersede virtually all existing revenue guidance under GAAP and is effective for annual reporting periods beginning after December 15, 2018. Early adoption for non-public entities is permitted starting with annual reporting periods beginning after December 15, 2016. The core principle contemplated by this new standard is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount reflecting the consideration to which the entity expects to be entitled in exchange for those goods or services. New disclosures about the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers are also required. In April and May 2016, the FASB also issued clarifying updates to the new standard specifically to address certain core principles including the identification of performance obligations, licensing guidance, the assessment of the collectability criterion, the presentation of taxes collected from customers, non-cash considerations, contract modifications and completed contracts at transition. The Company is currently evaluating the impact that the updated guidance will have on the Company’s financial statements and related disclosures. As part of the evaluation process, the Company is holding regular meetings with key stakeholders from across the organization to discuss the impact of the standard on its existing contracts. The Company is utilizing a bottom-up approach to analyze the impact of the standard on its portfolio of contracts by reviewing the Company’s current accounting policies and practices to identify potential differences that would result from applying the requirements of the new standard to the Company’s existing revenue contracts. As part of its implementation project, the Company has prepared analysis with respect to revenue stream scoping, performed contract reviews, developed a preliminary gap analysis, and begun to address revised disclosure requirements. The Company is in the process of assessing the impact of the Acton and Tyson acquisitions on the work previously completed as part of the implementation project. The Company is still completing this evaluation and has not yet determined the impact on its financial statements. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). This guidance revises existing practice related to accounting for leases under ASC Topic 840, Leases (“ASC 840”) for both lessees and lessors. The new guidance requires lessees to recognize a right-of-use asset and a lease liability for virtually all of their leases (other than leases that meet the definition of a short-term lease). The lease liability will be equal to the present value of lease payments and the right-of-use asset will be based on the lease liability, subject to adjustment such as for initial direct costs. For income statement purposes, the new standard retains a dual model similar to ASC 840, requiring leases to be classified as either operating or finance. Operating leases will result in straight-line expense (similar to current accounting by lessees for operating leases under ASC 840) while finance leases will result in a front-loaded expense pattern (similar to current accounting by lessees for capital leases under ASC 840). While the new standard maintains similar accounting for lessors as under ASC 840, the new standard reflects updates to, among other things, align with certain changes to the lessee model. The new standard will be effective for fiscal years beginning after December 15, 2019, and interim periods within fiscal years beginning after December 15, 2020. Early adoption is permitted for all entities. The Company is currently evaluating the impact of the pronouncement on its consolidated financial statements. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230) - Classification of Certain Cash Receipts and Cash Payments. The standard is intended to eliminate diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The new standard will be effective for the fiscal years beginning after December 15, 2018. Early adoption is permitted for all entities. The Company does not believe the pronouncement will have a material impact on its consolidated financial statements. In December 2016, the FASB issued ASU 2016-19, Technical Corrections and Improvements, stating that software licenses should be accounted for as the acquisition of an intangible asset and of a liability incurred. This new standard will be effective for annual periods beginning after December 15, 2017, and interim periods in annual periods beginning after December 15, 2018. The Company plans to adopt this pronouncement for the annual period ending December 31, 2018 and is still evaluating the potential impact from adoption of this new accounting pronouncement on its financial statements. In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805) - Clarifying the Definition of a Business. This new standard will be effective for annual periods beginning after December 15, 2018. This guidance changes the definition of a business to assist entities in evaluating when a set of transferred assets and activities constitutes a business. The guidance requires an entity to evaluate if substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets; if so, the set of transferred assets and activities is not a business. The guidance also requires a business to include at least one substantive process and narrows the definition of outputs by more closely aligning it with how outputs are described in ASC 606, Revenue from Contracts with Customers. Early adoption is permitted for all entities. The Company is still evaluating the potential impact from adoption of this new accounting pronouncement on its financial statements. Recently Adopted Accounting Standards From time to time, new accounting pronouncements are issued by the FASB or other standard setting bodies that are adopted by the Company as of the specified effective date. In October 2016, the FASB issued ASU 2016-16, Income Taxes (Topic 740) - Intra-Entity Transfers of Assets Other Than Inventory. The standard is intended to improve the accounting for the income tax consequences of intra-entity transfers of assets other than inventory. The new standard will be effective for annual reporting periods beginning after December 15, 2018. Early adoption is permitted for all entities as long as entities adopt at the beginning of an annual reporting period. The Company elected to early adopt this standard effective January 1, 2018. The pronouncement had no material impact on the Company’s condensed consolidated financial statements. During December 2017, shortly after the Tax Cuts and Jobs Act (the “Tax Act”) was enacted, the Securities and Exchange Commission (“SEC”) issued Staff Accounting Bulletin No. 118, Income Tax Accounting Implications of the Tax Cuts and Jobs Act (“SAB 118”) which provides guidance on accounting for the Tax Act’s impact. SAB 118 provides a measurement period, which in no case should extend beyond one year from the Tax Act enactment date, during which a company acting in good faith may complete the accounting for the impacts of the Tax Act under ASC Topic 740. Per SAB 118, companies must reflect the income tax effects of the Tax Act in the reporting period in which the accounting under ASC Topic 740 is complete. To the extent the accounting for certain income tax effects of the Tax Act is incomplete, companies can determine a reasonable estimate for those effects and record a provisional estimate in the financial statements in the first reporting period in which a reasonable estimate can be determined. If a company cannot determine a provisional estimate to be included in the financial statements, it should continue to apply ASC 740 based on the provisions of the tax laws that were in effect immediately prior to the Tax Act being enacted. If a company is unable to provide a reasonable estimate of the impacts of the Tax Act in a reporting period, a provisional amount must be recorded in the first reporting period in which a reasonable estimate can be determined. As a result of the Tax Act, the Company remeasured its net deferred tax liabilities and recognized a provisional net benefit of $28.1 million. In addition, based on information currently available, the Company recorded a provisional income tax expense of $2.4 million related to the deemed repatriation of foreign earnings. The Company recorded a minor adjustment to the provisional amounts recorded in its financial statements for the year ended December 31, 2017 (see Note 9) and continues to evaluate the provisions of the Tax Act including guidance from the Department of Treasury and Internal Revenue Service. Additionally, the Company expects to file its US tax return for 2017 during the fourth quarter of 2018 and any changes to the estimates used to the final tax positions for temporary differences, earnings and profits will result in adjustments of the remeasurement amounts for the Tax Act recorded as of December 31, 2017. The Company continues to evaluate the impact of the Global Low Taxed Intangible Income (“GILTI”) provision of the Tax Act. The Company is required to make an accounting policy election of either (1) treating GILTI as a current period expense when incurred or (2) factoring such amounts into the Company’s measurement of its deferred taxes. The Company has not completed its analysis and has not made a determination of its accounting policy for GILTI. In February 2018, the FASB issued ASU 2018-02, Income Statement-Reporting Comprehensive Income (Topic 220) - Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, to address a specific consequence of the Tax Act by allowing a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Act’s reduction of the US federal corporate income tax rate. ASU 2018-02 is effective for all entities for fiscal years beginning after December 15, 2018, with early adoption permitted, and is to be applied either in the period of adoption or retrospectively to each period in which the effect of the change in the US federal corporate income tax rate in the Tax Act is recognized. The Company elected to early adopt this standard and record an adjustment in the period of adoption (i.e. as of January 1, 2018) of $2.5 million from accumulated other comprehensive loss to accumulated deficit that related to stranded tax effects related to currency translation adjustments. ASU 2018-02 also requires issuers to disclose its policy for releasing income tax effects from accumulated other comprehensive income. The Company’s accounting policy is to release income tax effects with respect to currency translation matters on a portfolio basis.
