Summary of Significant Accounting Polices | Note 2: Summary of Significant Accounting Policies Basis of Presentation Our accompanying consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles (“GAAP”) and the accounting policies described below. Our consolidated financial statements include the accounts of all wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. The preparation of financial statements in accordance with GAAP requires that these Consolidated Financial Statements and most of the disclosures in these Notes be presented on a historical basis, as of or for the current annual period or prior annual periods. The consolidated financial position and results of operations and cash flows (including segment information) presented herein include those of Custom Truck One Source, Inc. as of December 31, 2021 and since the date of the Acquisition. Financial information presented for periods prior to the Acquisition represent those of Nesco Holdings and its subsidiaries. Use of Estimates We prepare our consolidated financial statements in conformity with GAAP, which requires us to use judgment to make estimates that directly affect the amounts reported in our consolidated financial statements and accompanying notes. Significant estimates are used for items including, but not limited to, the useful lives and residual values of our rental equipment, and the allocation of purchase price related to business combinations. In addition, estimates are used to test both long-lived assets, goodwill, and indefinite-lived assets for impairment, and to determine the fair value of impaired assets, if any impairment exists. These estimates are based on our historical experience and on various other assumptions we believe to be reasonable under the circumstances. We review our estimates on an ongoing basis using information currently available, and we revise our recorded estimates as updated information becomes available, facts and circumstances change, or actual amounts become determinable. Actual results could differ from our estimates. Recently Adopted Accounting Standards Leases In February 2016, the Financial Accounting Standards Board (“FASB”) issued new guidance to account for leases (“Topic 842”). This guidance revised prior practice related to accounting for leases under Topic 840, for both lessees and lessors. Topic 842 requires that lessees recognize: (a) a lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis; and (b) a right-of-use (“ROU”) asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. Effective January 1, 2021, the Company adopted Topic 842. In connection with the adoption of Topic 842, the Company recognized lease liabilities and ROU assets as of January 1, 2021, as further described in Note 10: Leases as Lessee. The comparative prior period financial statement information has not been restated and continues to be reported under the accounting standards in effect for those periods (e.g., under Topic 840). Additionally, pursuant to Topic 842, accounting and recognition for leases qualifying as finance leases is unchanged from the prior accounting and recognition requirements under Topic 840, which referred to such leases as capital leases. As of January 1, 2021, we had capital lease obligations of approximately $10.5 million which became “finance leases” under Topic 842. The adoption of Topic 842 did not have a significant impact on the recognition of leasing revenue; however, pursuant to the requirements of Topic 842, the Company records changes in estimated collectability of operating lease trade receivables directly against rental revenue. Such amounts were previously classified as selling, general and administrative expenses. The Company elected the package of practical expedients permitted under the transition guidance within the new standard that allows it to not reassess: (a) whether any expired or existing contracts are or contain leases, (b) the lease classification for any expired or existing leases and (c) initial direct costs for any expired or existing leases. Historical financial information was not updated, and the financial disclosures required under Topic 842 are not provided for periods prior to January 1, 2021. Measurement of Current Expected Credit Losses In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses: Measurement of Credit Losses on Financial Instruments , which amended ASC Topic No. 326 (“Topic 326”). Topic 326 follows an impairment model (known as the current expected credit loss, or “CECL,” model) that is based on expected losses rather than incurred losses. Under the CECL model, we estimate credit losses over the contractual term of our non-operating lease trade receivables and our financing receivables based on relevant historical information from historical experience and adjusted for current conditions and reasonable and supportable forecasts that affect collectability. Credit losses relating to these financial assets are recorded through the allowance for doubtful accounts. Topic 326 was adopted effective January 1, 2021, and the effect of this guidance was immaterial to the Company’s consolidated results of operations, financial position and cash flows. Simplifying the Test for Goodwill Impairment In January 2017, the FASB issued ASU 2017-04, Intangibles – Goodwill and Other: Simplifying the Test for Goodwill Impairment , intended to simplify the subsequent accounting for goodwill acquired in a business combination. Prior guidance required utilizing a two-step process to review goodwill for impairment. A second step was required if there was an indication that an impairment may exist, and the second step required calculating the potential impairment by comparing the implied fair value of a reporting unit’s goodwill (as if purchase accounting were performed on the testing date) to the carrying amount of the goodwill. The new guidance eliminates the second step from the goodwill impairment test. Under the new guidance, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount, and then recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value (although the loss should not exceed the total amount of goodwill allocated to the reporting unit). We adopted this guidance effective January 1, 2021; however, as discussed in Note 11: Goodwill and Intangible Assets, there was no impairment of goodwill in the years ended December 31, 2021, 2020 or 2019. Accordingly, the adoption of this standard did not have any impact on our consolidated financial statements. Recently Issued Accounting Pronouncements Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity In August 2020, the FASB issued ASU 2020-06, Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity , which simplifies the accounting for certain financial instruments with characteristics of liabilities and equity, including convertible instruments and contracts in an entity's own equity. Among other changes, the guidance made revisions to Topic 815-40, which provides guidance on how an entity must determine whether a contract qualifies for a scope exception from derivative accounting. The amendments to Topic 815-40 change the scope of contracts that are recognized as assets or liabilities. This ASU is effective for interim and annual periods beginning after December 15, 2021, and adoption of the ASU can either be on a modified retrospective or full retrospective basis. The impact of this guidance on the Company’s consolidated financial statements is currently being evaluated. Issuer’s Accounting for Certain Modifications or Exchanges of Freestanding Equity-Classified Written Call Options In May 2021, the FASB issued ASU 2021-04, Issuer’s Accounting for Certain Modifications or Exchanges of Freestanding Equity-Classified Written Call Options . This ASU addresses the previous lack of specific guidance in the accounting standards codification related to modifications or exchanges of freestanding equity-classified written call options (such as warrants) by specifying the accounting for various modification scenarios. The ASU is effective for interim and annual periods beginning after December 15, 2021. The impact of this guidance on the Company’s consolidated financial statements is currently being evaluated. Accounting for Contract Assets and Contract Liabilities from Contracts with Customers In October 2021, the FASB issued ASU 2021-08, Accounting for Contract Assets and Contract Liabilities from Contracts with Customers . This ASU improves the comparability for both the recognition and measurement of acquired revenue contracts with customers at the date of and after a business combination and requires that an entity (acquirer) recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Topic 606. The amended guidance specifies for all acquired revenue contracts regardless of their timing of payment (1) the circumstances in which the acquirer should recognize contract assets and contract liabilities that are acquired in a business combination and (2) how to measure those contract assets and contract liabilities, thereby providing consistent recognition and measurement guidance for revenue contracts with customers acquired in a business combination and revenue contracts with customers not acquired in a business combination. The ASU is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years, and should be applied prospectively to business combinations occurring on or after the effective date of the amendments. Early adoption of the amendments is permitted, and an entity that early adopts in an interim period should apply the amendments (1) retrospectively to all business combinations for which the acquisition date occurs on or after the beginning of the fiscal year that includes the interim period of early application and (2) prospectively to all business combinations that occur on or after the date of initial application. The impact of this guidance on the Company’s consolidated financial statements is currently being evaluated. Revenue Recognition We recognize revenue in accordance with two different accounting standards: (1) Topic 606 and Topic 842 for periods after January 1, 2021, and (2) Topic 606 and Topic 840, for periods prior to January 1, 2021. Under Topic 606, revenue from contracts with customers is measured based on the consideration specified in the contract with the customer, and excludes any sales incentives and amounts collected on behalf of third parties. A “performance obligation” is a promise in a contract to transfer a distinct good or service to a customer, and is the unit of account under Topic 606. We recognize revenue when we satisfy a performance obligation by transferring control over a product or service to a customer. The amount of revenue recognized reflects the consideration we expect to be entitled to in exchange for such products or services. Our contracts with customers generally do not include multiple performance obligations. Rental Revenue – Rental revenue is primarily comprised of revenues from rental agreements and freight charges billed to customers. We also charge customers for damaged equipment, which is assessed and billed at the time a rental asset is returned to the Company and recorded within Parts Sales and Services revenue. In connection with our adoption of Topic 842, beginning January 1, 2021, we record changes in the estimated collectability of operating lease trade receivables against rental revenue. Such amounts were previously classified as selling, general and administrative expenses. Our rental contracts are for various equipment, aftermarket parts and services under 28-day or monthly agreements which include automatic renewal provisions. The majority of our rental payments are due upon receipt, with a majority billed at the end of each 28-day or monthly period. Revenue is recognized ratably over the rental agreement period and in accordance with Topic 842, and, for periods prior to January 1, 2021, Topic 840. Unearned revenue is reported in deferred revenue and customer deposits in our consolidated balance sheets. We require our rental customers to maintain liability and property insurance covering the units during the rental term and to indemnify us from losses caused by the negligence of the customer, their employees or contractors. We also provide rental customers the opportunity to enter into contracts containing a rental purchase option (“RPO”). The RPO allows the customer to earn credit towards the purchase price of the leased equipment. The earned credit is based on rental payments made. Certain leases containing these purchase options are classified as sales-type leases because the RPO purchase price related to the leased equipment is considered to be a “bargain purchase option” in the lease. Revenue on these lease contracts is recognized at the point in time when the customer’s net purchase price for the equipment meets or falls below the fair value of the equipment. Revenue from these leases is recorded as equipment sales in the Consolidated Statements of Operations and Comprehensive Income (Loss). Equipment Sales – We sell both new and used equipment. The contractual sales price for each individual product represents the standalone selling price. Our used equipment is of a sufficiently unique nature, based on specific characteristics such as its age and usage, that it does not have an observable standalone selling price. Equipment sales revenue is recognized when equipment is delivered, which is when the transfer of control is considered passed to the customer. Payment is usually due within 30 days subsequent to transfer of control of the asset. There are no rights of return or warranties offered on equipment sales. Parts Sales and Services – We sell aftermarket parts and services. We derive our services revenue primarily from maintenance, repair and upfit services on heavy-duty trucks and cranes. Revenue from these services includes parts sales needed to complete the service work. We recognize services revenue as the service work is completed. We record revenue on a point in time basis as parts are delivered. The amount of consideration we receive for parts is based upon a list price net of discounts and incentives, and the impact of such variable consideration is factored into the amount of revenue we recognize at any point in time. The amount of consideration received for services is based upon labor hours expended and parts utilized to perform and complete the necessary services for our customers. There are no rights of return or warranties offered on parts sales. Payment is usually due and collected within 30 days subsequent to delivery of parts or performance of service. We record sales tax billed to customers and remitted to governmental authorities on a net basis and, consequently, these amounts are excluded from revenues and expenses. Sales taxes are recorded as accrued expenses when billed. Shipping and Handling Costs – We classify shipping and handling fees billed to customers related to the placement of rental units as rental revenue in our Consolidated Statements of Operations and Comprehensive Income (Loss). We include the related shipping and handling costs in cost of rental revenue, excluding depreciation, in our Consolidated Statements of Operations and Comprehensive Income (Loss). Shipping and handling fees billed to customers related to the sale of equipment and parts are recorded as equipment sales or parts sales and services revenue, respectively. The related shipping and handling costs are recorded in cost of equipment sales or cost of parts sales and services, respectively. Cash and Cash Equivalents Cash and cash equivalents consists of cash and short-term investments with remaining maturities of three months or less when acquired. The carrying amount of cash and cash equivalents approximates its fair value. The Company maintains deposits at financial institutions in excess of federally insured limits. Trade Receivables and Allowance for Credit Losses We are exposed to credit losses from trade receivables generated through our leasing, sales and service businesses. We assess each customer’s ability to pay for the products and services by conducting a credit review. The credit review considers expected billing exposure and timing for payment and the customer’s established credit rating. We perform a credit review of new customers at inception of the customer relationship and, for existing customers, when the customer transacts new leases or product orders after a period of dormancy. We also consider contract terms and conditions, country risk and business strategy in the evaluation. We monitor ongoing credit exposure through an active review of customer balances against contract terms and due dates. We may employ collection agencies and legal counsel to pursue recovery of defaulted receivables. The allowances for credit losses reflect the estimate of the amount of receivables that management assesses will be unable to be collected based on historical write-off experience and, as applicable, current conditions and reasonable and supportable forecasts that affect collectability. This estimate could require change based on changing circumstances, including changes in the economy or in the particular circumstances of individual customers. Accordingly, we may be required to increase or decrease the allowances. We review the adequacy of the allowance on a quarterly basis. The allowance for doubtful accounts is included in accounts receivable, net on our Consolidated Balance Sheets. Accounts receivable, net consisted of the following: (in $000s) December 31, 2021 December 31, 2020 Trade receivables $ 179,214 $ 67,305 Less: allowance for doubtful accounts (10,820) (6,372) Accounts receivable, net $ 168,394 $ 60,933 The relationship between bad debt expense and allowance for doubtful accounts is presented below: Year Ended December 31, (in $000s) 2021 2020 2019 Allowance - beginning of period $ 6,372 $ 4,654 $ 7,562 Accounts written off during period, net of recoveries (6,655) (2,047) (6,909) Bad debts expense 11,103 3,765 4,001 Allowance - end of period $ 10,820 $ 6,372 $ 4,654 In accordance with the adoption of Topic 842, effective January 1, 2021, specifically identifiable lease revenue receivables not deemed probable of collection are recorded as a reduction of rental revenue. The remaining provision for credit losses, which relates to product sales and services, is recorded in selling, general and administrative expense. For periods prior to January 1, 2021, the entire provision for credit losses was recorded in selling, general and administrative expense. Inventory Inventory is carried at the lower of cost or net realizable value. The Company periodically reviews inventories on hand and maintains reserves for slow-moving, excess, or obsolete inventories. Whole goods inventory is comprised of chassis, attachments (i.e., boom cranes, aerial lifts, digger derricks, dump bodies, etc.), and the in-process costs incurred in the final assembly of those units. As part of our business model, we sell unassembled individual whole goods and whole goods with varying levels of customization direct to consumers or dealers. Whole goods inventory also includes new equipment purchased specifically for resale to customers, which purchases are recorded directly to inventory when received. Cost is determined by specific identification for whole goods inventory. Aftermarket parts and services inventories are recorded at weighted average cost. Rental Equipment and Property and Equipment Rental Equipment Rental equipment is primarily comprised of the cost of truck-mounted aerial lifts, cranes, trucks, trailers, digger derricks, line equipment, cranes, pressure diggers, underground and other machinery and equipment. The rental equipment we purchase is recorded at cost and depreciated over the estimated rentable life of the equipment using the straight-line method over useful lives, depending on product categories, ranging from 5 to 7 years, to an estimated residual value, depending on product categories, ranging from 15% to 35% of cost. Depreciation of rental equipment commences when a rental unit is placed into the rental fleet and becomes available to rent and the cost is depreciated whether or not the equipment is on rent. We reevaluate the estimated rentable life as rental equipment is purchased, estimating the period that the asset will be held, considering factors such as historical rental activity and expectations of future rental activity. We also reevaluate the estimated residual values of the applicable rental equipment. The residual value of equipment is affected by factors that include equipment age, amount of usage and market conditions. Market conditions for used equipment sales can also be affected by external factors such as the economy, natural disasters, fuel prices, supply of similar used equipment, the market price for similar new equipment, and incentives offered by manufacturers of new equipment. These factors are considered when estimating future residual values and depreciation periods. Expenditures for repair and maintenance that extend the useful life of the equipment and are necessary to keep an equipment unit in rentable condition are capitalized and depreciated over the estimated remaining useful life of the equipment, which is the period the repair and maintenance is expected to provide future economic benefit. When making repairs, we dispose of damaged and replaced components at their net carrying values. The cost of routine and recurring maintenance activities related to the rental fleet are charged to expense as incurred. Property and Equipment Property and equipment is primarily comprised of land, buildings and improvements, machinery and equipment, and vehicles, and is carried at cost, net of accumulated depreciation. Depreciation is provided using the straight-line method based on useful lives ranging from four Leases as Lessee We determine if an arrangement is a lease at inception of an arrangement. Operating and finance lease assets and liabilities are recognized at the commencement date of the lease based on the present value of lease payments over the lease term. Lease assets represent the Company’s right to use an underlying asset for the lease term, while lease liabilities represent the Company’s obligation to make lease payments arising from the lease. As most leases do not provide an implicit interest rate, we use our incremental borrowing rate based on the information available at the lease commencement date, in determining the present value of lease payments. The length of a lease term includes options to extend or terminate the lease when it is reasonably certain that we will exercise those options. The Company made an accounting policy election to not recognize lease assets or liabilities for leases with a term of 12 months or less. Additionally, when accounting for leases, we combine payments for leased assets, related services and other components of a lease. Finally, we apply a portfolio approach to determine the discount rate for leases with similar characteristics. For our leases classified as operating, the ROU asset is subsequently measured throughout the lease term at the carrying amount of the lease liability, plus unamortized initial direct costs, plus/(minus) any unamortized prepaid/(accrued) lease payments, less the unamortized balance of lease incentives received. Lease expense for lease payments is recognized on a straight-line basis over the lease term. For our leases classified as finance leases, the ROU asset is subsequently amortized using the straight-line method from the lease commencement date to the earlier of the end of its useful life or the end of the lease term unless the lease transfers ownership of the underlying asset to the Company, or the Company is reasonably certain to exercise an option to purchase the underlying asset. In those cases, the ROU asset is amortized over the useful life of the underlying asset. We expect to exercise our options to purchase the rental equipment assets we lease under finance leases. Accordingly, the assets leased under the finance leases are included in rental equipment and property and equipment, and depreciation thereon is recognized in depreciation of rental equipment, cost of revenue and non-rental depreciation expense in the Consolidated Statements of Operations and Comprehensive Income (Loss). When we make our contractually required payments under finance leases, we allocate a portion to reduce the finance lease obligation and a portion is recognized as interest expense. Goodwill and Other Intangible Assets We recognize goodwill when the purchase price of an acquired business exceeds the fair value of net assets acquired. Goodwill is not amortized for financial reporting purposes. Goodwill is impaired when its carrying value exceeds its implied fair value. We perform our goodwill impairment analysis annually on October 1 or more frequently if an event or circumstance (such as a significant adverse change in the business climate, operating performance metrics, or legal factors) indicates that an impairment may have occurred. If the fair value of the reporting unit exceeds its carrying value, goodwill of the reporting unit is not considered impaired. If the carrying value of the reporting unit exceeds its fair value, then there is an indication impairment may exist. We estimate the fair value of our reporting units using both an income approach based on the present value of estimated future cash flows and a market approach based on traded values of selected companies. We believe this approach yields the most appropriate evidence of fair value. Determining the fair value of our reporting units is judgmental and involves the use of significant estimates and assumptions. We based our fair value estimates on assumptions that we believe are reasonable. Changes in these estimates and assumptions could materially affect the determination of fair value and goodwill impairment for our reporting units. Intangible assets with indefinite lives are not amortized but tested annually for impairment by comparing the carrying value of the asset to its fair value. We perform our impairment analysis on our intangible assets with indefinite lives annually on October 1 or more frequently if an event or circumstance indicates that an impairment loss may have occurred. See Note 11: Goodwill and Intangible Assets for additional information. Impairment of Long-Lived Assets, including Intangible Assets We evaluate the carrying value of long-lived assets held for use, including rental equipment and definite-lived intangible assets, for impairment whenever an event or circumstance has occurred (such as a significant adverse change in the business climate, operating performance metrics, or legal factors) which suggests that the carrying value may not be recoverable. Impairment of a long-lived asset held for use (or relative asset group, if applicable) is measured when the anticipated separately identifiable undiscounted cash flows from the asset are less than the carrying value. In that event, a loss is recognized based on the amount by which the carrying value exceeds the fair value. Fair value is determined primarily using anticipated cash flows discounted at a rate commensurate with the risk involved. Other intangible assets consist of customer relationships, non-compete agreements and trade names. We amortize intangible assets with finite lives over the period the economic benefits are estimated to be consumed. Definite lived intangibles are amortized using the straight-line method over their useful life, as we believe this method best matches the pattern of economic benefit. See Note 11: Goodwill and Intangible Assets for additional information. Fair Value Measurements Fair value is defined as an exit price representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date in the principal or most advantageous market. Fair value is a market-based measurement that is determined based on inputs, which refer broadly to assumptions that market participants use in pricing assets and liabilities. These inputs can be readily observable, market corroborated, or generally unobservable. Fair Value Hierarchy - In measuring fair value, we use observable market data when available and minimize the use of unobservable inputs. Unobservable inputs may be required to value certain financial instruments due to complexities in contract terms. Inputs used in fair value measurements are categorized into three fair value hierarchy levels for disclosure purposes. The entire fair value measurement is categorized based on the lowest level of input that is significant to the fair value measurement. The three levels of the fair value hierarchy are: Level 1 - Inputs that reflect unadjusted quoted prices are available in active markets for identical assets or liabilities as of the reporting date. Active markets are those in which transactions for the asset or liability occur with both sufficient frequency and volume to provide pricing information on an ongoing basis. Level 2 - Inputs that reflect quoted prices for similar assets and liabilities are available in active markets, and inputs other than quoted prices that are observable for the assets or liabilities, either directly or indirectly, for substantially the full term of the financial instruments. Level 3 - Inputs that are generally less observable or from unobservable sources in which there is little or no market data. These inputs may be used with internally developed methodologies that result in our best estimate of fair value. Valuation Techniques - Assets and liabilities measured at fair value are based on one or more of the following three valuation techniques: Market approach - Technique that uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities. Income approach - Technique that converts future amounts to a single present amount based upon market expectations (including present value techniques, option-pricing, and excess earnings models). Cost approach - Technique that estimates the amount that would be required to replace the service capacity of an asset (i.e. replacement cost). Assets and Liabilities with Recurring Fair Value Measurements - Certain assets and liabilities may be measured at fair value on an ongoing basis. We did not elect to apply the fair value option for recording financial assets and financial liabilities. Other than the interest rate collar and warrants liability, we do not have any assets or liabilities which we measure at fair value on a recurring basis. Assets and Liabilities with Nonrecurring Fair Value Measurements - Certain assets and liabilities are not measured at fair value on an ongoing basis. These assets and liabilities, which include long-lived assets, goodwill, and intangible assets, are subject to fair value adjustment in certain circumstances. From time to time, the fair value is determined on these assets as part of related impairment tests. For certain assets and liabilities acquired in business combinations, we record the fair value as of the acquisition date. Refer to Note 3: Business Combination, for the fair values of assets acquired and liabilities assumed in connection with our business combinations. Other than acquisition adjustments, no adjustments to fair value or fair value measurements were required for non-financial assets and liabilities for all periods presented. See Note 11: Goodwill and Intangible Assets and Note 15: Fair Value Measurements for additional information. Deferred Financing Costs Direct costs incurred in connection with the issuance, and amendments thereto, of our debt are capitalized and amortized over the terms of the respective agreements using the effective interest method, or the straight-line method when not materially different than the effective interest met |
