Revenues by reporting segment are presented in note 12 of our condensed consolidated financial statements, using the revenue captions reflected in our consolidated statements of operations. We believe that the disaggregation of our revenues from contracts to customers as reflected above, coupled with further discussion below and the reporting segments in note 12, depict how the nature, amount, timing and uncertainty of our revenues and cash flows are affected by economic factors. For further information related to our accounting for revenues pursuant to Topic 606 and Topic 842, see Significant Accounting Policies in note 2 to our Annual Report on Form 10-K for the year ended December 31, 2019.

Receivables and contract assets and liabilities

We manage credit risk associated with our accounts receivables at the customer level. Because the same customers typically generate the revenues that are accounted for under both Topic 606 and Topic 842, the discussions below on credit risk and our allowance for doubtful accounts address our total revenues from Topic 606 and Topic 842.

We believe concentration of credit risk with respect to our receivables is limited because our customer base is comprised of a large number of geographically diverse customers. No single customer accounted for more than 10% of our revenues on an overall or segment basis for any of the periods presented in this Quarterly Report on Form 10-Q. We manage credit risk through credit approvals, credit limits and other monitoring procedures.

Pursuant to Topic 842 and Topic 326 for rental and non-rental receivables, respectively, we maintain an allowance for doubtful accounts that reflects our estimate of our expected credit losses. Our allowance is estimated using a loss rate model based on delinquency. The estimated loss rate is based on our historical experience with specific customers, our understanding of our current economic circumstances, reasonable and supportable forecasts, and our own judgment as to the likelihood of ultimate payment based upon available data. Our largest exposure to doubtful accounts is in our rental operations. We perform credit evaluations of customers and establish credit limits based on reviews of our customers’ current credit information and payment histories. We believe our credit risk is somewhat mitigated by our geographically diverse customer base and our credit evaluation procedures. The actual rate of future credit losses, however, may not be similar to past experience. Our estimate of doubtful accounts could 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 our allowance for doubtful accounts.

We do not have material contract assets, impairment losses associated therewith, or material contract liabilities associated with contracts with customers. Our contracts with customers do not generally result in material amounts billed to customers in excess of recognizable revenue. We did not recognize material revenues during the three month periods ended March 31, 2020 or 2019 that was included in the contract liability balance as of the beginning of such periods.

We estimated the fair value of our reporting units by equally weighting results from the income approach and the market approach and we compared those fair values to the carrying values of our four reporting units with carrying values, and determined that our Equipment Rental Component 2 reporting unit had a fair value less than its carrying value, resulting in a $62.0 million impairment charge. The impairment was largely due to Equipment Rental Component 2’s forecasted declines in 2020 rental revenues, which was driven by the decrease in equipment rental demand that began in March 2020 as COVID-19’s impact became more widespread across our geographic footprint, combined with our revenue growth rate and cash flow assumptions for the remaining forecast period under the income approach, and the decline in the fair value of Equipment Rental Component 2 based on the market approach from declining business enterprise values of comparable companies in our industry, resulting in a decrease in revenue and EBITDA multiples of those companies. We determined that our Equipment Rental Component 1, Used Equipment Sales and Parts Sales reporting units were not impaired as their respective fair values exceeded their respective carrying values by approximately 34%, 90%, and 40%, respectively.

Significant assumptions inherent in the valuation methodologies for goodwill are employed and include, prospective financial information, growth rates, terminal value, discount rates, and comparable multiples from publicly traded companies in our industry. The inputs and variables used in determining the fair value of a reporting unit require management to make certain assumptions regarding the impact of operating and macroeconomic changes, as well as estimates of future cash flows. Our estimates regarding future cash flows are based on historical experience and projections of future operating performance, including revenues, margins and operating expenses. We also make certain forecasts about future economic conditions, such as the timing and duration of economic expansion or contraction cycles in our business, interest rates, and other market data. Many of the factors used in assessing fair value are outside the control of management, and these assumptions and estimates may change in future periods. An adverse change in any of the assumptions used in our impairment testing (e.g. projected revenue and profit, discount rates, industry price multiples, etc.), including the uncertainty related to the depth and duration of COVID-19’s impact on our forecasted cash flows, could affect our fair value measurements and result in future impairments. If we are unable to achieve the financial forecasts used in our impairment analysis, we may also be required to record an impairment charge to our goodwill.    

The impairment charges are non-cash items and will not affect our cash flows, liquidity or borrowing capacity under the senior credit facility, and the charge is excluded from our financial results in evaluating our financial covenant under the senior secured credit facility.

we continue to evaluate the new guidance of ASU 2019-12, we currently do not expect the guidance to have a material impact on our consolidated financial statements.     

In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which provides optional guidance for a limited time to ease the potential burden in accounting for or recognizing the effects of reference rate reform, particularly, the risk of cessation of the London Interbank Offered Rate (“LIBOR”) on financial reporting. The guidance provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendments are elective and are effective upon issuance for all entities through December 31, 2022. The amendments of this ASU should be applied on a prospective basis. The Company is currently evaluating the impact of the new guidance.

In March 2020, the Securities and Exchange Commission (“SEC”) adopted final rules that amend the financial disclosure requirements for subsidiary issuers and guarantors of registered debt securities in Rule 3-10 of Regulation S-X. The SEC also amended the disclosure requirements for affiliates whose securities are pledged as collateral for registered securities in Rule 3-16 of Regulation S-X. The disclosure requirements, as amended, are now relocated to newly created Rules 13-01 and 13-02 in Regulation S-X, while the amended eligibility requirements remain in Rule 3-10. The SEC amended its financial disclosure requirements for companies that conduct registered debt offerings involving subsidiaries as either issuers or guarantors and affiliates whose securities are pledged as collateral. The SEC also narrowed the circumstances that require separate financial statements of subsidiary issuers and guarantors and streamlined the alternative disclosures required in lieu of those statements. Further, the SEC replaced the requirement for separate financial statements of affiliates whose securities are pledged as collateral for registered securities with requirements similar to those adopted for subsidiary issuers and guarantors. The rule is effective January 4, 2021, but earlier compliance is permitted. The Company is currently evaluating the impact of the final rules.

Pronouncements Adopted in 2020

Credit Losses

On January 1, 2020, we adopted Accounting Standards Codification Topic 326, Credit Losses (Topic 326). This standard establishes an impairment model (known as the current expected credit loss (“CECL”) model) that is based on expected losses rather than incurred losses. Under the new guidance, we recognize an allowance for our estimate of expected credit losses over the entire contractual term of our receivables from the date of initial recognition of the financial instrument. Measurement of expected credit losses are based on relevant forecasts that affect collectability. Topic 326 applies to trade receivables from certain revenue transactions including receivables from equipment sales, parts and service sales. Under Topic 606 (Revenue from Contracts with Customers), revenue is recognized when, among other criteria, it is probable that the entity will collect the consideration to which it is entitled for goods or services transferred to a customer. At the point that these trade receivables are recorded, they become subject to the CECL model and estimates of expected credit losses over their contractual life are recorded at inception based on historical information, current conditions, and reasonable and supportable forecasts. The adoption of Topic 326 did not have a material impact on our consolidated financial statements and related disclosures or our existing internal controls because our non-rental accounts receivable are of short duration and there is not a material difference between incurred losses and expected losses.

Fair Value

On January 1, 2020, we adopted ASU No. 2018-13, Fair Value Measurement - Disclosure Framework. ASU 2018-13 modifies the disclosure requirements for fair value measurements. Entities are no longer required to disclose the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, but public companies are required to disclose the range and weighted average used to develop significant unobservable inputs for Level 3 fair value measurements. The adoption of ASU 2018-13 did not have a material impact on our consolidated financial statements and footnotes.
