1. DESCRIPTIONBASIS OF BUSINESSPRESENTATION
The accompanying condensed consolidated financial statements of Ameresco, Inc. (including its subsidiaries, the “Company”) was organized as a Delaware corporation on April 25, 2000. The Company is a provider of energy efficiency solutions for facilities throughout North America and Europe. The Company provides solutions, both services and products, that enable customers to reduce their energy consumption, lower their operating and maintenance costs and realize environmental benefits. The Company’s comprehensive set of solutions includes upgrades to a facility’s energy infrastructure and the construction and operation of small-scale renewable energy plants. It also sells certain photovoltaic (“PV”) equipment worldwide. The Company operates in the United States, Canada and Europe.
The Company is compensated through a variety of methods, including: 1) direct payments based on fee-for-services contracts (utilizing lump-sum or cost-plus pricing methodologies); 2) the sale of energy from the Company’s energy assets and the sale of energy assets; and 3) direct payment for PV equipment and systems.
The condensed consolidated financial statements as of March 31, 2019, and for the three months ended March 31, 2019 and 2018, are unaudited, pursuant to certain rules and regulations of the Securities and Exchange Commission, and include, in the opinion of the Company, normal recurring adjustments necessary for a fair presentation in conformity with accounting principles generally accepted in the United States (“GAAP”) of the results for the periods indicated, which, however,indicated.
The results of operations for the three months ended March 31, 2020 are not necessarily indicative of results which may be expected for the full year. The December 31, 20182019 consolidated balance sheet data was derived from audited financial statements, but certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted. The interim condensed consolidated financial statements, and notes thereto, should be read in conjunction with the audited consolidated financial statements for the year ended December 31, 2018,2019, and notes thereto, included in the Company’s annual report on Form 10-K for the year ended December 31, 20182019 filed with the Securities and Exchange Commission on March 8, 2019.4, 2020.
SIGNIFICANT RISKS AND UNCERTAINTIES

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
PrinciplesIn March 2020, the World Health Organization categorized Coronavirus Disease 2019 (“COVID-19”) as a pandemic, and the President of Consolidationthe United States declared the COVID-19 outbreak a national emergency.
The accompanyingCompany’s condensed consolidated financial statements include the accounts of the Company, its subsidiaries in which the Company has a controlling financial interest and four investment funds formed to fund the purchase and operation of solar energy systems, which are consolidated with the Company as variable interest entities (“VIE”). The Company uses a qualitative approach in assessing the consolidation requirement for VIEs. This approach focuses on determining whether the Company has the power to direct the activities of the VIE that most significantly affect the VIE’s economic performance and whether the Company has the obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE. For all periods presented, the Company has determined that it is the primary beneficiary in all but one of its operational VIEs. The Company evaluates its relationships with the VIEs on an ongoing basis to ensure that it continues to be the primary beneficiary. All significant intercompany accounts and transactions have been eliminated. Gains and losses from the translation of all foreign currency financial statements are recorded in accumulated other comprehensive loss, net, within stockholders’ equity. The Company prepares its condensed consolidated financial statements in conformity with GAAP.
Use of Estimates
GAAP requires management to makereflect estimates and assumptions made by management that affect the reported amounts of assets and liabilities theand disclosure of contingent assets and liabilities at the date of the condensed consolidatingconsolidated financial statements and the reported amounts of revenue and expenses during the reporting period.periods presented. The most significantCompany considered the impact of COVID-19 on the assumptions and estimates used and assumptions useddetermined that there were no material adverse impact on the Company’s first quarter 2020 results of operations.
The severity of the impact of the COVID-19 pandemic on the Company's business will depend on a number of factors, including, but not limited to, the duration and severity of the pandemic and the extent and severity of the impact on the Company's customers, all of which are uncertain and cannot be predicted. The Company's future results of operations and liquidity could be adversely impacted by delays in payments of outstanding receivable amounts beyond normal payment terms, delays in obtaining signed customer contracts for awarded projects, supply chain disruptions and uncertain demand. As of the date of issuance of these condensed consolidated financial statements, relatethe extent to management’s estimateswhich the COVID-19 pandemic may materially impact the Company's financial condition, liquidity, or results of final construction contract profit in accordance with accounting for long-term contracts, allowance for doubtful accounts, inventory reserves, realizationoperations is uncertain.
On March 27, 2020, the U.S. government enacted the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) which includes modifications to the limitation on business interest expense and net operating loss provisions, and provides a payment delay of project development costs, fair valueemployer payroll taxes during 2020 after the date of derivative financial instruments, accounting for business acquisitions, stock-based awards, impairment of goodwill and long-lived assets, asset retirement obligations (“AROs”), leases, income taxes, self insurance reserves and potential liability in conjunction with certain commitments and contingencies. Actual results could differ from those estimates.

The Company is self-insured for employee health insurance.estimates the payment of approximately $5,000 of employer payroll taxes otherwise due in 2020 will be delayed with 50% due by December 31, 2021 and the remaining 50% by December 31, 2022. The maximum exposureCARES Act permits net operating losses from the 2018, 2019, and 2020 tax years to be carried back to the previous five tax years (beginning with the earliest year first). The Company estimates the discrete benefit associated with the net operating loss provisions of the CARES Act to be approximately $2,000 and an estimated refund of taxes paid in fiscal year 2019 underprior years of approximately $1,300.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
The accounting policies of the plan was $150 per covered participant, after which reinsurance takes effect. The liability for unpaid claims and associated expenses, including incurred but not reported claims, is determined by management and reflectedCompany are set forth in Note 2 to the consolidated financial statements contained in the Company’s condensed consolidated balance sheets2019 annual report on Form 10-K. The Company includes herein certain updates to those policies.
Accounts Receivable and allowance for Credit Losses
Accounts receivable are stated at the amount management expects to collect from outstanding balances. Effective January 1, 2020, the Company adopted ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (ASU 2016-13) prospectively. This ASU replaces the incurred loss impairment model with an expected credit loss impairment model for financial instruments, including trade receivables. The amendment requires entities to consider forward-looking information to estimate expected credit losses, resulting in accrued expenses and otherearlier recognition of losses for receivables that are current liabilities.or not yet due, which were not considered under the previous accounting guidance. The liability is calculated based on historical data,Company

which considers both the frequency and settlement amountperformed an assessment of claims. The Company’s estimated accrual for this liability could be different than its ultimate obligation if variables such as the frequency or amount of future claims differ significantly from management’s assumptions.
Cash and Cash Equivalents
Cash and cash equivalents includes cash on deposit, overnight repurchase agreements and amounts invested in highly liquid money market funds. Cash equivalents consist of short term investments with original maturities of three months or less. The Company maintains accounts with financial institutions and the balances in such accounts, at times, exceed federally insured limits. This credit risk is divided among a number of financial institutions that management believes to be of high quality. The carrying amount of cash and cash equivalents approximates its fair value measured using level 1 inputs per the fair value hierarchy as defined in Note 10.
Restricted Cash
Restricted cash consists of cash and cash equivalents held in an escrow account in association with construction draws for energy savings performance contracts (“ESPC”), construction of energy assets, operations and maintenance (“O&M”) reserve accounts and cash collateralized letters of credit as well as cash required under term loans to be maintained in debt service reserve accounts until all obligations have been indefeasibly paid in full. These accounts are primarily invested in highly liquid money market funds. The carrying amount of the cash and cash equivalents in these accounts approximates its fair value measured using level 1 inputs per the fair value hierarchy as defined in Note 10. Restricted cash also includes funds held for clients, which represent assets that, based upon the Company’s intent, are restricted for use solely for the purposes of satisfying the obligations to remit funds to third parties, primarily utility service providers, relating to the Company’s enterprise energy management services. As of March 31, 2019 and December 31, 2018, the Company classified the non-current portion of restricted cash of $20,920 and $19,637, respectively, in other assets on its condensed consolidated balance sheets.
Accounts Receivable
Accounts receivable are stated at the amount management expects to collect from outstanding balances. An allowance for doubtful accounts is provided for those accounts receivable considered to be uncollectiblecredit losses based upon historical experience, and management’s evaluation of outstanding accounts receivable.receivable, consideration of its customers’ financial conditions and current macroeconomic and market conditions and determined that no adjustment was required to retained earnings upon adoption.
The Company’s methodology to estimate the allowance for credit losses includes quarterly assessments of historical bad debt write off experience, current economic and market conditions, management’s evaluation of outstanding accounts receivable, and the Company’s forecasts. Due to the short-term nature of its receivables, the estimate of credit losses is primarily based on aged accounts receivable balances and the financial condition of customers. In addition, specific allowance amounts are established to record the appropriate provision for customers that have a higher probability of default. Bad debts are written off against the allowance when identified. As part of its assessment, the Company also considered the current and expected future economic and market conditions due to the COVID-19 pandemic and determined that the estimate of credit losses was not significantly impacted as of March 31, 2020.
Changes in the allowance for doubtful accounts are as follows:

Accounts Receivable Retainage
Accounts receivable retainage represents amounts due from customers, but where payments are withheld contractually until certain construction milestones are met. Amounts retained typically range from 5% to 10% of the total invoice. The Company classifies as a current asset those retainages that are expected to be billed in the next twelve months. No amounts were determined to be uncollectible as of March 31, 2019 and December 31, 2018.
Inventory
Inventories, which consist primarily of PV solar panels, batteries and related accessories, are stated at the lower of cost (“first-in, first-out” method) or net realizable value (determined as the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation). Provisions have been made to reduce the carrying value of inventory to the net realizable value.
Prepaid Expenses
Prepaid expenses consist primarily of short-term prepaid expenditures that will amortize within one year.
AMERESCO, INC.
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) - (Continued)
(in thousands, except per share amounts)

Federal ESPC Receivable
Federal ESPC receivable represents the amount to be paid by various federal government agencies for work performed and earned by the Company under specific ESPCs. The Company assigns certain of its rights to receive those payments to third-parties that provide construction and permanent financing for such contracts. Upon completion and acceptance of the project by the government, typically within 24 to 36 months of construction commencement, the assigned ESPC receivable from the government and corresponding ESPC liability are eliminated from the Company’s condensed consolidated financial statements.
Project Development Costs
The Company capitalizes as project development costs only those costs incurred in connection with the development of energy projects, primarily direct labor, interest costs, outside contractor services, consulting fees, legal fees and travel, if incurred after a point in time where the realization of related revenue becomes probable. Project development costs incurred prior to the probable realization of revenue are expensed as incurred. The Company classifies as a current asset those project development efforts that are expected to proceed to construction activity in the twelve months that follow. The Company periodically reviews these balances and writes off any amounts where the realization of the related revenue is no longer probable. Project development costs of $217 and $639 were included in other long-term assets at March 31, 2019 and December 31, 2018, respectively.
Property and Equipment
Property and equipment consists primarily of office and computer equipment, and is recorded at cost. Major additions and improvements are capitalized as additions to the property and equipment accounts, while replacements, maintenance and repairs that do not improve or extend the life of the respective assets are expensed as incurred. Depreciation and amortization of property and equipment are computed on a straight-line basis over the following estimated useful lives:
Asset ClassificationEstimated Useful Life
Furniture and office equipmentFive years
Computer equipment and software costsThree to five years
Leasehold improvementsLesser of term of lease or five years
AutomobilesFive years
LandUnlimited
Gains orcredit losses on disposal of property and equipment are reflected in selling, general and administrative expenses in the condensed consolidated statements of income.
Energy Assets
Energy assets consist of costs of materials, direct labor, interest costs, outside contract services, deposits and project development costs incurred in connection with the construction of small-scale renewable energy plants that the Company owns. These amounts are capitalized and amortized to cost of revenues in the Company’s condensed consolidated statements of income on a straight line basis over the lives of the related assets or the terms of the related contracts.
The Company capitalizes interest costs relating to construction financing during the period of construction. Capitalized interest is included in energy assets, net in the Company’s condensed consolidated balance sheets. Capitalized interest is amortized to cost of revenues in the Company’s condensed consolidated statements of income on a straight line basis over the useful life of the associated energy asset. There was $788 and $994 of interest capitalized for the three months ended March 31, 2020 and 2019 and 2018, respectively.
Routine maintenance costs are expensed in the current year’s condensed consolidated statements of income to the extent that they do not extend the life of the asset. Major maintenance, upgrades and overhauls are required for certain components of the Company’s assets. In these instances, the costs associated with these upgrades are capitalized and are depreciated over the shorter of the remaining life of the asset or the period until the next required major maintenance or overhaul.
Included in energy assets are financing lease assets and accumulated depreciation of financing lease assets. For additional information see the Sale-Leaseback section below. Financing leases were referred to as capital leases under previous guidance.
The Company evaluates its long-lived assets for impairment as events or changes in circumstances indicate the carrying value of these assets may not be fully recoverable. Examples of such triggering events applicable to the Company’s assets
AMERESCO, INC.
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) - (Continued)
(in thousands, except per share amounts)

include a significant decrease in the market price of a long-lived asset or asset group or a current-period operating or cash flow loss combined with a history of operating or cash flow losses or a projection or forecast that demonstrates continuing losses associated with the use of a long-lived asset or asset group.
The Company evaluates recoverability of long-lived assets to be held and used by estimating the undiscounted future cash flows before interest associated with the expected uses and eventual disposition of those assets. When these comparisons indicate that the carrying value of those assets is greater than the undiscounted cash flows, the Company recognizes an impairment loss for the amount that the carrying value exceeds the fair value.
The Company has applied for and received cash grant awards from the U.S. Treasury Department (the “Treasury”) under Section 1603 of the American Recovery and Reinvestment Act of 2009 (the “Act”). The Act authorized the Treasury to make payments to eligible persons who place in service qualifying renewable energy projects. The grants are paid in lieu of investment tax credits. All of the cash proceeds from the grants were used and recorded as a reduction in the cost basis of the applicable energy assets. If the Company disposes of the property, or the property ceases to qualify as specified energy property, within five years from the date the property is placed in service, then a prorated portion of the Section 1603 payment must be repaid.
The Company last received a Section 1603 grant during the year ended December 31, 2014. No further Section 1603 grant payments are expected to be received as the program has expired.
For tax purposes, the Section 1603 payments are not included in federal and certain state taxable income and the basis of the property is reduced by 50% of the payment received. Deferred grant income of $6,499 and $6,637 recorded in the accompanying condensed consolidated balance sheets as of March 31, 2019 and December 31, 2018, respectively, represents the benefit of the basis difference to be amortized to income tax expense over the life of the related property.
Leases
All significant lease arrangements are recognized at lease commencement. Operating lease right-of-use (“ROU”) assets and lease liabilities are recognized at commencement. An ROU asset and corresponding lease liability are not recorded for leases with an initial term of 12 months or less (short term leases) as the Company recognizes lease expense for these leases as incurred over the lease term.
 ROU assets represent the Company’s right to use an underlying asset during the reasonably certain lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. The Company’s lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. The Company uses its incremental borrowing rate, which is updated annually or when a significant event occurs that would indicate a significant change in rates, based on the information available at commencement date, in determining the present value of lease payments. The operating lease ROU asset also includes any lease payments related to initial direct cost and prepayments and excludes lease incentives. Lease expense is recognized on a straight-line basis over the lease term. The Company has lease agreements with lease and non-lease components, which are generally accounted for as a single component. See Note 8 for additional discussion on the Company’s leases.
Deferred Financing Fees
Deferred financing fees relate to the external costs incurred to obtain financing for the Company. Deferred financing fees are amortized over the respective term of the financing using the effective interest method, with the exception of the Company’s revolving credit facility and construction loans, as discussed in Note 15, for which deferred financing fees are amortized on a straight-line basis over the term of the agreement. Deferred financing fees are presented on the condensed consolidated balance sheets as a reduction to long-term debt and financing lease liabilities.
Goodwill and Intangible Assets
The Company has classified as goodwill the amounts paid in excess of fair value of the net assets (including tax attributes) of companies acquired in purchase transactions. The Company has recorded intangible assets related to customer contracts, customer relationships, non-compete agreements, trade names and technology, each with defined useful lives. The Company assesses the impairment of goodwill and intangible assets that have indefinite lives on an annual basis (December 31st) and whenever events or changes in circumstances indicate that the carrying value of the asset may not be recoverable.
AMERESCO, INC.
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) - (Continued)
(in thousands, except per share amounts)

The process of evaluating the potential impairment of goodwill requires significant judgment. The Company regularly monitors current business conditions and other factors including, but not limited to, adverse industry or economic trends, restructuring actions and projections of future results. The Company estimates the reporting units fair value and compares it with the carrying value of the reporting unit, including goodwill. If the fair value is greater than the carrying value of its reporting unit, no impairment is recorded. Fair value is determined using both an income approach and a market approach. The estimates and assumptions used in the Company’s calculations include revenue growth rates, expense growth rates, expected capital expenditures to determine projected cash flows, expected tax rates and an estimated discount rate to determine present value of expected cash flows. These estimates are based on historical experiences, the Company’s projections of future operating activity and its weighted-average cost of capital. If the fair value is less than the carrying value, an impairment loss is recognized for the amount that the carrying amount of a reporting unit, including goodwill, exceeds its fair value, limited to the total amount of goodwill allocated to that reporting unit. The impairment charge would be recorded to earnings in the condensed consolidated statements of income. Judgment is required in determining whether an event has occurred that may impair the value of goodwill or identifiable intangible assets.
Acquired intangible assets other than goodwill that are subject to amortization include customer contracts and customer relationships, as well as software/technology, trade names and non-compete agreements. The intangible assets are amortized over periods ranging from one to fifteen years from their respective acquisition dates. The Company evaluates its intangible assets for impairment consistent with, and part of, their long-lived assets evaluation, as discussed in Energy Assets above.
See Note 5 for additional disclosures.
Other Assets
Other assets consist primarily of notes and contracts receivable due to the Company from various customers and non-current restricted cash. Other assets also include, the fair value of derivatives determined to be assets, the non-current portion of project development costs, accounts receivable retainages, sale-leaseback deferred loss and deferred contract costs.
Asset Retirement Obligations
The Company recognizes a liability for the fair value of required AROs when such obligations are incurred. The Company records, as liabilities, the fair value of the AROs on a discounted basis when incurred and reasonably estimated which is typically at the time the assets are installed or operating. Over time the liabilities increase due to the change in present value, and initial capitalized costs are depreciated over the useful life of the related assets. Upon satisfaction of the ARO conditions any difference between the recorded ARO liability and the actual retirement cost incurred is recognized as an operating gain or loss in the condensed consolidated statements of income. See Note 6 for additional disclosures on the Company’s AROs.
Federal ESPC Liabilities
Federal ESPC liabilities, for both projects and energy assets, represent the advances received from third-parties under agreements to finance certain ESPC projects with various federal government agencies.
For projects related to the construction or installation of certain energy savings equipment or facilities developed for the government customer, upon completion and acceptance of the project by the government, typically within 24 to 36 months of construction commencement, the ESPC receivable from the government and corresponding ESPC liability is eliminated from the Company’s condensed consolidated balance sheet. Until recourse to the Company ceases for the ESPC receivables transferred to the investor, upon final acceptance of the work by the government customer, the Company remains the primary obligor for financing received.
For small-scale energy assets developed for the government customer that the Company owns and operates, upon final acceptance of the work by the government customer, the Company remains the primary obligor for financing received and the liability is eliminated from the Company’s condensed consolidated balance sheet as contract payments assigned by the customer are transferred to the investor.
Sale-Leaseback
During the first quarter of 2015, the Company entered into an agreement with an investor which gives the Company the option to sell and contemporaneously lease back solar photovoltaic (“solar PV”) projects. In September 2016, the Company amended this agreement to increase the investor’s commitment up to a maximum combined funding amount of $100,000 through June 30, 2017 on certain projects. In May 2017, the Company amended this agreement to extend the end date of the agreement to June 30, 2018. During the third quarter of 2018, the Company entered into an agreement with an investor which

gives the Company the option to sell and contemporaneously lease back solar PV projects through August 2019up to a maximum funding amount of $100,000. During the three months ended March 31, 2019 and 2018 the Company entered into no sale-leaseback agreements.
As part of these agreements, the Company is a party to a master lease agreement that provides for the sale of solar PV projects to a third-party investor and the simultaneous leaseback of the projects, which the Company then operates and maintains, recognizing revenue through the sale of the electricity and solar renewable energy credits generated by these projects. In sale-leaseback arrangements, the Company first determines whether the solar PV project under the sale-leaseback arrangement is “integral equipment.” A solar PV project is determined to be integral equipment when the cost to remove the project from its existing location, including the shipping and reinstallation costs of the solar PV project at the new site, including any diminution in fair value, exceeds 10% of the fair value of the solar PV project at the time of its original installation. When the leaseback arrangement expires, the Company has the option to purchase the solar PV project for the then fair market value or, in certain circumstances, renew the lease for an extended term. All solar PV projects sold to date under the sale-leaseback program have been determined by the Company not to be integral equipment as the cost to remove the project from its existing location would not exceed 10% of its original fair value.
For solar PV projects that the Company has determined not to be integral equipment, the Company then determines if the leaseback should be classified as a financing lease or an operating lease. All solar PV projects sold to date under the sale-leaseback program have been determined by the Company to be financing leases. For leasebacks classified as financing leases, the Company initially records a financing lease asset and financing lease obligation in its condensed consolidated balance sheet equal to the lower of the present value of the Company’s future minimum leaseback payments or the fair value of the solar PV project. For financing leasebacks, the Company defers any gain or loss, representing the excess or shortfall of cash received from the investor compared to the net book value of the asset in the Company’s condensed consolidated balance sheet at the time of the sale. The Company records the long term portion of any deferred gain or loss in other liabilities and other assets, respectively, and the current portion of any deferred gain and loss in accrued expenses and other current liabilities and prepaid expenses and other current assets, respectively, in its condensed consolidated balance sheet and amortizes the deferred amounts over the lease term in cost of revenues in its condensed consolidated statements of income. Net amortization expense in cost of revenues related to deferred gains and losses was $57 and $59 of net gains for the three months ended March 31, 2019 and2018, respectively.
A summary of amounts related to sale leasebacks in the Company’s condensed consolidated balance sheets is as follows:

Accordingly, these sales-leasebacks will remain under the previous guidance. See Note 8 for additional information on these sale-leasebacks.
Other Liabilities
Other liabilities consist primarily of deferred revenue related to multi-year operation and maintenance contracts which expire at various dates through 2033. Other liabilities also include the fair value of derivatives, the long term portion of sale-leaseback deferred gains, ESPC energy asset liabilities, ARO liability, and certain contingent consideration. See Note 10 for additional disclosures.

Revenue Recognition
The Company derives revenues from energy efficiency and renewable energy products and services. Energy efficiency products and services include the design, engineering, and installation of equipment and other measures to improve the efficiency, and control the operation, of a facility’s energy infrastructure. Renewable energy products and services include the construction of small-scale plants that produce electricity, gas, heat or cooling from renewable sources of energy, the sale of such electricity, gas, heat or cooling from plants that the Company owns, and the sale and installation of solar energy products and systems. Below is a description of the Company’s primary lines of business.
Projects - The Company’s principal service relates to energy efficiency projects, which entails the design, engineering and installation of, and assisting with the arranging of financing for an ever-increasing array of innovative technologies and techniques to improve the energy efficiency, and control the operation, of a building’s energy- and water- consuming systems. In certain projects, the Company also designs and constructs for a customer a central plant or cogeneration system providing power, heat and/or cooling to a building, or a small-scale plant that produces electricity, gas, heat or cooling from renewable sources of energy.
The Company recognizes revenue from the installation or construction of projects over time using the cost-based input method. The Company uses the total costs incurred on the the project relative to the total expected costs to satisfy the performance obligation.
When the estimate on a contract indicates a loss, or claims against costs incurred reduce the likelihood of recoverability of such costs, the Company records the entire estimated loss in the period the loss becomes known.
Operations & Maintenance (“O&M”) - After an energy efficiency or renewable energy project is completed, the Company often provides ongoing O&M services under a multi-year contract. These services include operating, maintaining and repairing facility energy systems such as boilers, chillers and building controls, as well as central power and other small-scale plants. For larger projects, the Company frequently maintains staff on-site to perform these services.
Maintenance revenue is recognized using the input method to recognize revenue. In most cases, O&M fees are fixed annual fees. Because the Company is on-site to perform O&M services, the services are typically a distinct series of promises, and those services have the same pattern of transfer to the customer (i.e., evenly over time), the Company records the revenue on a straight-line basis. Some O&M service contract fees are billed on time expended. In those cases, revenue is recorded based on the time expended in that month.
Energy Assets - The Company’s service offerings also includes the sale of electricity, processed renewable gas fuel, heat or cooling from the portfolio of assets that the Company owns and operates. The Company has constructed and is currently designing and constructing a wide range of renewable energy plants using landfill gas (“LFG”), wastewater treatment biogas, solar, biomass, other bio-derived fuels, wind and hydro sources of energy. Most of the Company’s renewable energy projects to date have involved the generation of electricity from solar PV and LFG or the sale of processed LFG. The Company purchases the LFG that otherwise would be combusted or vented, processes it, and either sells it or uses it in its energy plants. The Company has also designed and built, as well as owns, operates and maintains, plants that take biogas generated in the anaerobic digesters of wastewater treatment plants and turns it into renewable natural gas that is either used to generate energy on-site or that can be sold through the nation’s natural gas pipeline grid. Where the Company owns and operates energy producing assets, the Company typically enters into a long-term power purchase agreement (“PPA”) for the sale of the energy. Many of the Company’s energy assets also produce environmental attributes, including renewable energy credits (“RECs”) and Renewable Identification Numbers (“RINs”). In most cases, the Company sells these attributes under separate agreements with third parties other than the PPA customer.
The Company recognizes revenues from the sale and delivery of the energy output from renewable energy plants, over time as produced and delivered to the customer, in accordance with specific PPA contract terms. Environmental attributes revenue is recognized at a point in time, when the environmental attributes are transferred to the customer in accordance with the transfer protocols of the environmental attributes market that the Company operates in. In those cases where environmental attributes are sold to the same customer as the energy output, the Company records revenue monthly for both the energy output and the environmental attribute output, as generated and delivered to the customer.  =
Other - The Company’s service and product offerings also include integrated-PV and consulting and enterprise energy management services.
AMERESCO, INC.
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) - (Continued)
(in thousands, except per share amounts)

The Company recognizes revenues from delivery of engineering, consulting services and enterprise energy management services over time. For the sale of solar materials, revenue is recognized at a point in time when the Company has transferred physical control of the asset to the customer upon shipment.
To the extent a contract is deemed to have multiple performance obligations, the Company allocates the transaction price of the contract to each performance obligation using its best estimate of the standalone selling price of each distinct good or service in the contract.
Billings in excess of cost and estimated earnings represents advanced billings on certain construction contracts. Costs and estimated earnings in excess of billings represent certain amounts under customer contracts that were earned and billable but not invoiced.
See Note 3 for additional information on the Company’s revenues.
Cost of Revenues
Cost of revenues include the cost of labor, materials, equipment, subcontracting and outside engineering that are required for the development and installation of projects, as well as preconstruction costs, sales incentives, associated travel, inventory obsolescence charges, amortization of intangible assets related to customer contracts and, if applicable, costs of procuring financing. A majority of the Company’s contracts have fixed price terms; however, in some cases the Company negotiates protections, such as a cost-plus structure, to mitigate the risk of rising prices for materials, services and equipment.
Cost of revenues also include the costs of maintaining and operating the small-scale renewable energy plants that the Company owns, including the cost of fuel (if any) and depreciation charges.
Income Taxes
The Company provides for income taxes based on the liability method. The Company provides for deferred income taxes based on the expected future tax consequences of differences between the financial statement basis and the tax basis of assets and liabilities calculated using the enacted tax rates in effect for the year in which the differences are expected to be reflected in the tax return.
The Company accounts for uncertain tax positions using a “more-likely-than-not” threshold for recognizing and resolving uncertain tax positions. The evaluation of uncertain tax positions is based on factors that include, but are not limited to, changes in tax law, the measurement of tax positions taken or expected to be taken in tax returns, the effective settlement of matters subject to audit, new audit activity and changes in facts or circumstances related to a tax position. The Company evaluates uncertain tax positions on a quarterly basis and adjusts the level of the liability to reflect any subsequent changes in the relevant facts surrounding the uncertain positions.
The Company’s liabilities for uncertain tax positions can be relieved only if the contingency becomes legally extinguished through either payment to the taxing authority or the expiration of the statute of limitations, the recognition of the benefits associated with the position meet the “more-likely-than-not” threshold or the liability becomes effectively settled through the examination process.
The Company considers matters to be effectively settled once the taxing authority has completed all of its required or expected examination procedures, including all appeals and administrative reviews; the Company has no plans to appeal or litigate any aspect of the tax position; and the Company believes that it is highly unlikely that the taxing authority would examine or re-examine the related tax position. The Company also accrues for potential interest and penalties related to unrecognized tax benefits in income tax expense.
The Company has presented all deferred tax assets and liabilities as net and noncurrent on its condensed consolidated balance sheet as of March 31, 2019 and December 31, 2018, respectively.
See Note 7 for additional information on the Company’s income taxes.
Foreign Currency
The local currency of the Company’s foreign operations is considered the functional currency of such operations. All assets and liabilities of the Company’s foreign operations are translated into U.S. dollars at period-end exchange rates. Income and expense items are translated at average exchange rates prevailing during the period. Translation adjustments are accumulated as a separate component of stockholders’ equity. Foreign currency translation gains and losses are reported in the condensed
AMERESCO, INC.

consolidated statements of comprehensive income. Foreign currency transaction gains and losses are reported in the condensed consolidated statements of income.
Financial Instruments
Financial instruments consist of cash and cash equivalents, restricted cash, accounts and notes receivable, long-term contract receivables, accounts payable, accrued expenses, financing lease assets and liabilities, contingent considerations, short- and long-term borrowings, make-whole provisions, interest rate swaps, and commodity swaps. Because of their short maturity, the carrying amounts of cash and cash equivalents, restricted cash, accounts and notes receivable, accounts payable, accrued expenses, certain contingent considerations, and short-term borrowings approximate fair value.
Fair Value Measurements
The Company follows the guidance related to fair value measurements for all of its non-financial assets and non-financial liabilities, except for those recognized at fair value in the financial statements at least annually. These assets include goodwill and long-lived assets measured at fair value for impairment assessments, and non-financial assets and liabilities initially measured at fair value in a business combination.
The Company’s financial instruments include cash and cash equivalents, restricted cash, accounts and notes receivable, long-term contract receivables, accounts payable, accrued expenses, financing lease assets and liabilities, contingent considerations, short and long-term borrowings, interest rate swaps, and commodity swaps. Because of their short maturity, the carrying amounts of cash and cash equivalents, restricted cash, accounts and notes receivable, accounts payable, and accrued expenses approximate fair value. The carrying value of long-term variable-rate debt approximates fair value. Fair value of the Company’s debt is based on quoted market prices or on rates available to the Company for debt with similar terms and maturities, which are level two inputs of the fair value hierarchy, as defined in Note 10.    
The Company accounts for its interest rate swaps and commodity swaps as derivative financial instruments in accordance with the related guidance. Under this guidance, derivatives are carried on the Company’s condensed consolidated balance sheets at fair value. The fair value of the Company’s interest rate and commodity swaps are determined based on observable market data in combination with expected cash flows for each instrument. The Company accounts for its make-whole provision features as embedded derivatives in accordance with related guidance. Under this guidance, the derivative is bifurcated from its host contract and recorded on the Company’s condensed consolidated balance sheets at fair value. The fair value of the Company’s make-whole provisions are determined based on observable market data and a with and without model.
The consideration for the Company’s acquisitions often includes future payments that are contingent upon the occurrence of a particular event. The Company records a contingent consideration obligation for such contingent consideration payments at fair value on the acquisition date. The Company estimates the acquisition date fair value of contingent consideration obligations through valuation models that incorporate probability adjusted assumptions related to the achievement of the milestones and the likelihood of making related payments. Each period the Company revalues the contingent consideration obligations associated with the acquisition to fair value and records changes in the fair value as contingent consideration expense within the selling, general and administrative expenses line in our condensed consolidated statements of income. Increases or decreases in the fair value of the contingent consideration obligations can result from changes in assumed discount periods and rates, changes in the assumed timing and amount of revenue and expense estimates and changes in assumed probability with respect to the attainment of certain financial and operational metrics, among others. Significant judgment is employed in determining these assumptions as of the acquisition date and for each subsequent period. Accordingly, future business and economic conditions, as well as changes in any of the assumptions described above, can materially impact the amount of contingent consideration expense recorded in any given period. However, deferred consideration related to certain holdbacks and completion payments are considered short-term in nature. These amounts are recorded at full value and are only revalued if one of those underlying assumptions changes.
See Note 10 for additional information related to fair value measurements.
Stock-Based Compensation Expense
Stock-based compensation expense results from the issuance of shares of restricted common stock and grants of stock options to employees, directors, outside consultants and others. The Company recognizes the costs associated with restricted stock option grants, and employee stock purchases made via the Company’s Employee Stock Purchase Plan (the “ESPP”) using the fair value recognition provisions of accounting standards codification (“ASC”) 718, Compensation - Stock Compensation
AMERESCO, INC.

(in thousands, except per share amounts)

(“ASC 718”) on a straight-line basis over the vesting period of the awards. Certain option grants have performance conditions that must be achieved prior to vesting and are expensed based on the expected achievement at each reporting period. Stock-based compensation expense is also recognized in association with employee stock purchases related to the Company’s employee stock purchase plan.
Stock-based compensation expense is recognized based on the grant-date fair value. The Company estimates the fair value of the stock-based awards, including stock options, using the Black-Scholes option-pricing model. Determining the fair value of stock-based awards requires the use of highly subjective assumptions, including the fair value of the common stock underlying the award, the expected term of the award and expected stock price volatility.
The assumptions used in determining the fair value of stock-based awards represent management’s estimates, which involve inherent uncertainties and the application of management judgment. As a result, if factors change, and different assumptions are employed, the stock-based compensation could be materially different in the future. The risk-free interest rates are based on the U.S. Treasury yield curve in effect at the time of grant, with maturities approximating the expected life of the stock options.
The Company has no history of paying dividends. Additionally, as of each of the grant dates, there was no expectation that the Company would pay dividends over the expected life of the options. The expected life of the awards is estimated using historical data and management’s expectations. The Company uses historical volatility as the expected volatility assumption required in the Black-Scholes model.
The Company is required to recognize compensation expense for only the portion of options that are expected to vest. If there are any modifications or cancellations of the underlying invested securities or the terms of the stock option, it may be necessary to accelerate, increase or cancel any remaining unamortized stock-based compensation expense.
For the three months ended March 31, 2019 and 2018, the Company recorded stock-based compensation expense, including expense related to the ESPP, of $385 and $355, respectively, in connection with the stock-based payment awards. The compensation expense is allocated to selling, general and administrative expenses in the accompanying condensed consolidated statements of income based on the salaries and work assignments of the employees holding the options. As of March 31, 2019, there was $4,034 of unrecognized compensation expense related to non-vested stock option awards that is expected to be recognized over a weighted-average period of 2.3 years.
No awards to individuals who were not either an employee or director of the Company occurred during the three months ended March 31, 2019 or during the year ended December 31,2018.
Share Repurchase Program
In April 2016, the Company’s Board of Directors authorized the repurchase of up to $10,000 of the Company’s Class A common stock from time to time on the open market in privately negotiated transactions. In February 2017, the Company’s Board of Directors authorized an increase in the Company’s share repurchase authorization to $15,000 of the Company's Class A common stock from time to time on the open market or in privately negotiated transactions. The timing and amount of any shares repurchased will be determined by the Company's management based on its evaluation of market conditions and other factors. Any repurchased shares will be available for use in connection with its stock plans and for other corporate purposes. The repurchase program has and will be funded using the Company's working capital and borrowings under its revolving line of credit. The Company accounts for share repurchases using the cost method. Under this method, the cost of the share repurchase is recorded entirely in treasury stock, a contra equity account. During the three months ended March 31, 2019, the Company did not repurchase any shares of common stock. During the three months ended March 31, 2018, the Company repurchased 212 shares of common stock in the amount of $1,771, net of fees of $9.
Derivative Financial Instruments
In the normal course of business, the Company utilizes derivatives contracts as part of its risk management strategy to manage exposure to market fluctuations in interest and commodity rates. These instruments are subject to various credit and market risks. Controls and monitoring procedures for these instruments have been established and are routinely reevaluated. Credit risk represents the potential loss that may occur because a party to a transaction fails to perform according to the terms of the contract. The measure of credit exposure is the replacement cost of contracts with a positive fair value. The Company seeks to manage credit risk by entering into financial instrument transactions only through counterparties that the Company believes to be creditworthy.
AMERESCO, INC.
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) - (Continued)
(in thousands, except per share amounts)

Market risk represents the potential loss due to the decrease in the value of a financial instrument caused primarily by changes in interest rates and commodity prices. The Company seeks to manage market risk by establishing and monitoring limits on the types and degree of risk that may be undertaken. As a matter of policy, the Company does not use derivatives for speculative purposes. The Company considers the use of derivatives with all financing transactions to mitigate risk.
The Company recognizes cash flows from derivative instruments as operating activities in the condensed consolidated statements of cash flows. The effective portion of changes in fair value on interest rate swaps designated as cash flow hedges are recognized in the Company’s condensed consolidated statements of comprehensive income. Changes in fair value on derivatives not designated as hedges are recognized in the Company’s condensed consolidated statements of income.
The Company adopted ASU 2017-12 during the third quarter of 2018. Upon adoption, the Company recognized an increase to retained earnings and an accumulated other comprehensive loss of $432 to remove the cumulative effect of hedging ineffectiveness previously recognized in earnings, as of January 1, 2018, for contracts designated as hedging instruments that were outstanding at the beginning of the third quarter 2018.
See Notes 10 and 11 for additional information on the Company’s derivative instruments.
Earnings Per Share
Basic earnings per share is calculated using the Company’s weighted-average outstanding common shares, including vested restricted shares. When the effects are not anti-dilutive, diluted earnings per share is calculated using the weighted-average outstanding common shares; the dilutive effect of convertible preferred stock, under the “if converted” method; and the treasury stock method with regard to warrants and stock options; all as determined under the treasury stock method.

For the three months ended March 31, 2019 and 2018, the total number of shares of common stock related to stock options excluded from the calculation of dilutive shares, as the effect would be anti-dilutive, were 293 and 1,637, respectively.
Variable Interest Entities
Certain contracts are executed jointly through partnership and joint venture arrangements with unrelated third parties. The arrangements are often formed for the single business purpose of executing a specific project and allow the Company to share risks and/or secure specialty skills required for project execution.
        The Company evaluates each partnership and joint venture at inception to determine if it qualifies as a VIE under ASC 810, Consolidation. A variable interest entity is an entity used for business purposes that either (a) does not have equity investors with voting rights or (b) has equity investors who are not required to provide sufficient financial resources for the entity to support its activities without additional subordinated financial support. Upon the occurrence of certain events outlined in ASC 810, the Company reassesses its initial determination of whether the partnership or joint venture is a VIE.
        The Company also evaluates whether it is the primary beneficiary of each VIE and consolidates the VIE if the Company has both (a) the power to direct the economically significant activities of the entity and (b) the obligation to absorb losses of, or the right to receive benefits from, the entity that could potentially be significant to the VIE. The Company considers the contractual agreements that define the ownership structure, distribution of profits and losses, risks, responsibilities, indebtedness, voting rights and board representation of the respective parties in determining whether it qualifies as the primary beneficiary. The Company also considers all parties that have direct or implicit variable interests when determining whether it is the primary beneficiary. When the Company is determined to be the primary beneficiary, the VIE is consolidated. As required by ASC 810, management's assessment of whether the Company is the primary beneficiary of a VIE is continuously performed.
AMERESCO, INC.
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) - (Continued)
(in thousands, except per share amounts)

The Company generally aggregates the disclosures of its VIEs based on certain qualitative and quantitative factors including the purpose and design of the underlying VIEs, the nature of the assets in the VIE, and the type of involvement the Company has with the VIE including its role and type of interest held in the VIE. As of March 31, 2019, all the fully consolidated VIEs that make up the Company’s investment funds are similar in purpose, design, and the Company’s involvement and, as such, are aggregated in one disclosure. See Note 12 for additional disclosures.
Equity Method Investment
The Company has entered into a joint venture that the Company has determined it is not the primary beneficiary of the VIE using the methodology previously described for variable interest entities. The Company does not consolidate the operations of this joint venture and treats the joint venture as an equity method investment. See Note 12 for additional information on the Company’s equity method investment.
Redeemable Non-Controlling Interests
In each of September 2015, June 2017, June 2018 and October 2018, the Company formed an investment fund with a different third party investor which granted the applicable investor ownership interests in the net assets of certain of the Company’s renewable energy project subsidiaries. The Company currently has four such investment funds each with a different third party investor.
The Company entered into these agreements in order to finance the costs of constructing energy assets which are under long-term customer contracts. The Company has determined that these entities qualify as VIEs and that it is the primary beneficiary in the operational partnerships for accounting purposes. Accordingly, the Company will consolidate the assets and liabilities and operating results of the entities in its condensed consolidated financial statements. The Company will recognize the investors’ share of the net assets of the subsidiaries as redeemable non-controlling interests in its condensed consolidated balance sheet.
The Company has determined that the provisions in the contractual arrangements represent substantive profit-sharing arrangements. The Company has further determined that the appropriate methodology for attributing income and loss to the redeemable non-controlling interests each period is a balance sheet approach referred to as the hypothetical liquidation at book value (“HLBV”) method. Under the HLBV method, the amounts of income and loss attributed to the redeemable non-controlling interests in the condensed consolidated statements of income reflect changes in the amounts the investors would hypothetically receive at each balance sheet date under the liquidation provisions of the contractual agreements, assuming the net assets of this funding structure were liquidated at recorded amounts. The investors’ non-controlling interest in the results of operations of this funding structure is determined as the difference in the non-controlling interest’s claim under the HLBV method at the start and end of each reporting period, after taking into account any capital transactions, such as contributions or distributions, between the Company’s subsidiaries and the investors. The use of the HLBV methodology to allocate income to the redeemable non-controlling interest holders may create volatility in the Company’s condensed consolidated statements of income as the application of HLBV can drive changes in net income available and loss attributable to the redeemable non-controlling interests from quarter to quarter.
The Company classified the non-controlling interests with redemption features that are not solely within the control of the Company outside of permanent equity on its condensed consolidated balance sheets. The redeemable non-controlling interests will be reported using the greater of their carrying value at each reporting date as determined by the HLBV method or the estimated redemption values in each reporting period.
See Note 12 and Note 13 for additional disclosures.
Recent Accounting Pronouncements
Leases
In February 2016, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2016-02, Leases (Topic 842). The guidance in this ASU supersedes the leasing guidance in Topic 840, Leases. Under the new guidance, the Company is electing to only recognize lease assets and lease liabilities on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the condensed consolidated statements of income. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years.
AMERESCO, INC.

On January 1, 2019, the Company adopted ASU No. 2016-02 using the modified retrospective approach of applying the new standard at the adoption date. See Note 8 for the impact of the adoption and the new disclosures required by this standard.
In March 2019, the FASB issued ASU No. 2019-01, Leases (Topic 842): Codification Improvements, which provides clarification and improvements to the previous issued guidance. The standard is effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years. The Company is currently evaluating the impact ASU 2019-01 on its condensed consolidated financial statements, but does not expect that the adoption of this guidance will have a significant impact on its condensed consolidated financial statements.
Intangibles-Goodwill and Other
In August 2018, the FASB issued ASU No. 2018-15, Intangibles - Goodwill and Other - Internal-Use-Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract, which clarifies the accounting for implementation, setup, and upfront costs and aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. The new standard is effective interim and annual periods beginning after December 15, 2019, with early adoption permitted, and can be applied either retrospectively or prospectively. The Company adopted this guidance as of January 1, 2019 and the adoption did not have an impact on the Company’s condensed consolidated financial statements.
Fair Value Measurement
In August 2018, the FASB issuesissued ASU No. 2018-13 Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement, which modifies the disclosure requirements on fair value measurements. ASU 2018-13 is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years.

Accounts receivable retainage represents amounts due from customers, but where payments are withheld contractually until certain construction milestones are met. Amounts retained typically range from 5% to 10% of the total invoice. The Company classifies as a current asset those retainages that are expected to be billed in the next twelve months. Unbilled revenue, presented as costs and estimated earnings in excess of billings, represent amounts earned and billable that were not invoiced at the end of the fiscal period.
Contract assets represent the Company’s rights to consideration in exchange for services transferred to a customer that have not been billed as of the reporting date. The Company’s rights to consideration are generally unconditional at the time its performance obligations are satisfied.

At the inception of a contract, the Company expects the period between when it satisfies its performance obligations, and when the customer pays for the services, will be one year or less. As such, the Company has elected to apply the practical expedient which allows the Company to not adjust the promised amount of consideration for the effects of a significant financing component, when a financing component is present.
When the Company receives consideration, or such consideration is unconditionally due, from a customer prior to transferring goods or services to the customer under the terms of a sales contract, the Company records deferred revenue, which represents a contract liability. Such deferred revenue typically results from billings in excess of costs incurred and advanceadvanced payments received on project contracts. As of March 31, 2020 and December 31, 2019, the Company classified $6,129$5,320 and $5,560, respectively, as a non-current liability, included in other liabilities on the condensed consolidated balance sheets, for those performance obligations expected to be completed beyond the next twelve months.
The decrease in contract assets for the three months ended March 31, 2020 was primarily due to billings of $152,612, offset in part by revenue recognized of approximately $137,596. The decrease in contract liabilities was primarily driven by recognition of revenue as performance obligations were satisfied exceeding increases from the receipt of advance payments from customers and related billings. For the three months ended March 31, 2020, the Company recognized revenue of $19,552 that was previously included in the beginning balance of contract liabilities and billed customers $15,651. Changes in contract liabilities are also driven by reclassifications to or from contract assets as a result of timing of customer payments.
The increase in contract assets for the three months ended March 31, 2019 was primarily due to revenue recognized of approximately $90,344, offset in part by billings of approximately $90,895. The increase in contract liabilities was primarily driven by the receipt of advance paymentspayment from customers, and related billings, exceeding reductions from recognition of revenue as performance obligations were satisfied. For the three months ended March 31, 2019, the Company recognized revenue of $24,095 and billed customers $18,929, that was previously included in the beginning balance of contract liabilities. Changes in contract liabilities, are also driven by reclassifications to or from contract assets as a result of timing of customer payments.
The decrease in contract assets for the three months ended March 31, 2018 was primarily due to billings of approximately $120,072, offset in part by revenue recognized of $87,440. The change in contract liabilities was primarily driven by the receipt of advance payments from customers, and related billings, exceeding reductions from recognition of revenue as performance obligations were satisfied. For the quarter ended March 31, 2018, the Company recognized revenue of $17,843, and billed customers $16,678, that was previously included in the beginning balance of contract liabilities.$18,929. Changes in contract liabilities are also driven by reclassifications to or from contract assets as a result of timing of customer payments.
Contracts are often modified for a change in scope or other requirements. The Company considers contract modifications to exist when the modification either creates new or changes the existing enforceable rights and obligations. Most of the Company’s contract modifications are for goods or services that are not distinct from the existing performance obligations.  The effect of a contract modification on the transaction price, and the measure of progress for the performance obligation to which it relates, is recognized as an adjustment to revenue (either as an increase or decrease) on a cumulative catchup basis.
Performance obligationsObligations
A performance obligation is a promise in a contract to transfer a distinct good or service to the customer. Performance obligations are satisfied as of a point in time or over time and are supported by contracts with customers. For most of the

Company’s contracts, there are multiple promises of goods or services. Typically, the Company provides a significant service of integrating a complex set of tasks and components such as design, engineering, construction management, and equipment procurement for a project contract. The bundle of goods and services are provided to deliver one output for which the customer has contracted. In these cases, the Company considers the bundle of goods and services to be a single performance obligation. The Company may also promise to provide distinct goods or services within a contract, such as a project contract for installation of energy conservation measures and post-installation O&M services. In these cases the Company separates the contract into more than one performance obligation. If a contract is separated into more than one performance obligation, the Company allocates the total transaction price to each performance obligation in an amount based on the estimated relative standalone selling prices of the promised goods or services underlying each performance obligation.
Backlog - The Company’s remaining performance obligations (hereafter referred to as “backlog”) represent the unrecognized revenue value of the Company’s contract commitments. The Company’s backlog may vary significantly each reporting period based on the timing of major new contract commitments and the backlog may fluctuate with currency movements. In addition, our customers have the right, under some circumstances, to terminate contracts or defer the timing of the Company’s services and their payments to us.the Company. At March 31, 2019,2020, the Company had backlog of approximately $1,674,600.$2,181,643. Approximately 27%26% of our March 31, 20192020 backlog is anticipated to be recognized as revenue in the next twelve months and the remaining, thereafter.

The Company has applied the practical expedient for certain revenue streams to exclude the value of remaining performance obligations for (i) contracts with an original expected term of one year or less or (ii) contracts for which the Company recognizes revenue in proportion to the amount it has the right to invoice for services performed.
Contract acquisition costs:Acquisition Costs
The Company accounts for certain acquisition costcosts over the life of the contract, consisting primarily of commissions when paid. Commission costs are incurred commencing at contract signing. Commission costs are allocated across all performance obligations and deferred and amortized over the contract term on a progress towardstoward completion basis.
As of March 31, 2020 and December 31, 2019, included in other assets in the accompanying condensed consolidated balance sheets, were $1,735 and $1,735, respectively, of capitalized commission costs related to contracts that were not completed. For contracts that have a duration of less than one year, the Company follows a practical expedient and expenses these costs when incurred. During the three months ended March 31, 20192020 and 2018,2019, the amortization of commission costs related to contracts werewas not material and havehas been included in the accompanying condensed consolidated statements of income.
As discussed in Note 2, theThe Company capitalizes costs incurred related to the development of projects prior to contract signing as it is partial fulfillment of its performance obligations. obligations.  Capitalized project development costs include only those costs incurred in connection with the development of energy projects, primarily direct labor, interest costs, outside contractor services, consulting fees, legal fees and travel, if incurred after a point in time where the realization of related revenue becomes probable. Project development costs incurred prior to the probable realization of revenue are expensed as incurred. The Company classifies as a current asset those project development efforts that are expected to proceed to construction activity in the twelve months that follow. The Company periodically reviews these balances and writes off any amounts where the realization of the related revenue is no longer probable. Project development costs of $697 and $217 were included in other long-term assets as of March 31, 2020 and December 31, 2019, respectively. During the three months ended March 31, 2020 and 2019, $1,635 and 2018, $2,777, and $2,440, respectively, of project development costs were recognized in the condensed consolidated statements of income on projects that converted to customer contracts.

NoNaN impairment charges in connection with the Company’s commission costs or project development costs were recorded during the periodsthree months ended March 31, 20192020 and 2018.2019.


4. BUSINESS ACQUISITIONS AND RELATED TRANSACTIONS
The Company accounts for acquisitions using the acquisition method in accordance with ASC 805, Business Combinations. The purchase price for each has been allocated to the net assets based on their estimated fair values at the date of each acquisition as set forth in the table below. The excess purchase price over the estimated fair value of the net assets, which are calculated using level 3 inputs per the fair value hierarchy as defined in Note 10, acquired has been recorded as goodwill. Intangible assets, if identified, have been recorded and are being amortized over periods ranging from one to fifteen years. See Note 5 for additional information.
Determining the fair value of certain assets and liabilities assumed is judgmental in nature and often involves the use of significant estimates and assumptions. Certain amounts below are provisional based on our best estimates using information available as of the reporting date. The Company is waiting for information to become available to finalize its valuation of certain elements of these transactions. Specifically, the assigned values for energy assets, intangibles, and goodwill are provisional in nature and subject to change upon the completion of the final valuation of such elements.
In January 2019,During the three months ended March 31, 2020, the Company completed an acquisition of a Massachusetts based solar operations and maintenance firm for consideration of $1,279. The final purchase price is subject to a net working capital adjustment, dependent on the level ofdid not complete any acquisitions.

During the Company’s annual goodwill impairment test theretesting in 2019, all reporting units had fair values that exceeded their carrying values by at least 15%. If the Company believes that one or more indicators of impairment have been no events that would have triggered a need foroccurred, then the Company will perform an interim impairment test. The Company has the option to perform a qualitative assessment (commonly referred to as "step zero" test) to determine whether further quantitative analysis for impairment of goodwill and indefinite-lived intangible assets is necessary. The qualitative assessment includes a review of macroeconomic conditions, industry and market considerations, internal cost factors, and the Company’s own overall financial and share price performance, among other factors. If, after assessing the totality of events or circumstances the Company determines that it is not more-likely-than-not that the fair value of a reporting unit is less than its carrying amount, the Company does not need to perform a quantitative analysis. Upon assessment, the Company concluded it was not more likely than not that the fair value of the reporting units were less than the carrying value of the reporting units as of March 31, 2020. The Company will monitor future results and will perform a test if indicators trigger an impairment review. At this time, the Company has not deemed the impact that the current macroeconomic environment surrounding the COVID-19 pandemic has or is expected to have on the business to be a triggering event for impairment purposes.
Separable intangible assets that are not deemed to have indefinite lives are amortized over their useful lives. The Company annually assesses whether a change in the life over which the Company’s assets are amortized is necessary, or more frequently if events or circumstances warrant.

The contingent consideration will be paid yearly,annually, commencing in 2020, if any of the cumulative revenue targets are achieved and theachieved. The fair value of the earn-out will be periodically re-evaluated at each reporting period and adjustments will be recorded as needed. See Note 10 for additional information.

In November 2018, the Company completed an acquisition of certain lease options, which provided for aan earn-out if the lease option is exercised and if certain financial metrics are achieved. The Company evaluated the acquired lease options and concluded that the fair-value of this contingent liability was approximately $363, which was subsequently increased to $379$378 at December 31, 2019 which remained consistent at March 31, 20192020, and is recorded in accrued expenses and other current liabilities and other liabilities on the condensed consolidated balance sheets. Payments will be made when milestones are achieved. The contingent liability will be periodically re-evaluated at each reporting period and adjustments will be recorded as needed.                                                           See Note 10 for additional information.

10. FAIR VALUE MEASUREMENT
The Company recognizes itscertain financial assets and liabilities at fair value on a recurring basis (at least annually). Fair value is defined as the price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date.
Three levels of inputs that may be used to measure fair value are as follows:
Level 1:  Inputs are based upon unadjusted quoted prices for identical instruments traded in active markets.
Level 2:  Inputs are based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model based valuation techniques for which all significant assumptions are observable in the market or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
Level 3:  Inputs are generally unobservable and typically reflect management’s estimates of assumptions that market participants would use in pricing the asset or liability. The fair values are therefore determined using model-based techniques that include option pricing models, discounted cash flow models, and similar techniques.
The following table presents the input level used to determine the fair values of the Company’s financial instruments measured at fair value on a recurring basis:

The fair value of the Company’s interest rate swaps was determined using cash flow analysis on the expected cash flow of the contract in combination with observable market-based inputs, including interest rate curves and implied volatilities. As part of this valuation, the Company considered the credit ratings of the counterparties to the interest rate swaps to determine if a credit risk adjustment was required.

The fair value of the Company’s commodity swaps was determined using a cash flow analysis on the expected cash flow of the contract in combination with observable forward price inputs obtained from a third-party pricing source. As part of this valuation, the Company considered the credit ratings of the counterparties to the commodity swaps to determine if a credit risk adjustment was required.
The fair value of the Company’s make-whole provisions were determined by comparing them against the rates of similar debt instruments under similar terms without a make-whole provision obtained from various highly rated third-party pricing sources.
The fair value of the Company’s contingent consideration liabilities were determined by evaluating the acquired asset’s future financial forecasts and evaluating which, if any, of the cumulative revenue targets, financial metrics and/or milestones are likely to be met. The Company has classified contingent consideration related to certain acquisitions within Levellevel 3 of the fair value hierarchy because the fair value is derived using significant unobservable inputs, which include discount rates and probability-weighted cash flows. The Company determined the fair value of its contingent consideration obligations based on a probability-weighted income approach derived from financial performance estimates and probability assessments of the

attainment of certain targets. The Company establishes discount rates to be utilized in its valuation models based on the cost to borrow that would be required by a market participant for similar instruments. In determining the probability of attaining certain technical, financial and operation targets, the Company utilizes data regarding similar milestone events from our own experience, while considering the inherent difficulties and uncertainties in developing a product. On a quarterly basis, the Company reassesses the probability factors associated with the financial, operational and technical targets for its contingent consideration obligations. Significant judgment is employed in determining the appropriateness of these assumptions as of the acquisition date and for each subsequent period.
The key assumptions as of March 31, 20192020, related to the contingent consideration from a previousthe acquisition of certain assets of Chelsea Group Limited, used in the model include a discount rate of 18% for purposes of discounting the low and base case scenarios associated with achievement of the financial based earn-out. The probabilities assigned to these scenarios were 50% for both the low and base case scenarios. An increase or decrease in the probability of achievement of any scenario could result in a significant increase or decrease to the estimated fair value of the contingent consideration liability.

  The key assumptions as of March 31, 2019, related to the contingent consideration from a previous acquisition of certain lease options, used in the model include a discount rate of 18% for purposes of discounting the low, base and high case scenarios associated with achievement of the financial based earn-out. The probabilities assigned to these scenarios were 20% for the low case, 75% for the base case and 5% for the high case. An increase or decrease in the probability of achievement of any scenario could result in a significant increase or decrease to the estimated fair value of the contingent consideration liability.
The following table sets forth a summary of changes in fair value of contingent liabilities classified as Level 3 for the three months ended March 31, 2020 and March 31, 2019:
Three Months EndedThree Months Ended

The fair value of financial instruments is determined by reference to observable market data and other valuation techniques, as appropriate. The only category of financial instruments where the difference between fair value and recorded book value is notable is long-term debt. At March 31, 20192020 and December 31, 20182019 the fair value of the Company’s long-term debt was estimated using discounted cash flows analysis, based on the Company’s current incremental borrowing rates for similar types of borrowing arrangements which are considered to be level two inputs. There have been no transfers in or out of level two or level three financial instruments for the three months ended March 31, 20192020 and the year ended December 31, 2018. 2019.
Based on the analysis performed, the fair value and the carrying value of the Company’s long-term debt, excluding financing leases, are as follows:

In the third quarter of 2018, the Company adopted ASU 2017-12, which resulted in an increase to retained earnings and accumulated other comprehensive loss of $432 to remove the cumulative effect of hedging ineffectiveness previously recognized in earnings, as of January 1, 2018, for contracts designated as hedging instruments that were outstanding at the beginning of the third quarter 2018. Upon adoption of the ASU, the impact to reclassify the ineffectiveness of the Company’s hedge instruments in connection with prior periods was recorded. Accordingly, the Company’s condensed consolidated statement of changes in redeemable non-controlling interests and stockholders’ equity for the three months ended March 31, 2018 reflect the adoption of ASU 2017-12 .

12. INVESTMENT FUNDS AND OTHER VARIABLE INTEREST ENTITIES
Investment Funds
In each of September 2015, June 2017, June 2018, and October 2018, and December 2019, the Company formed an investment fund with a different third partythird-party investor which granted the applicable investor ownership interests in the net assets of certain of the Company’s renewable energy project subsidiaries. The Company currently has four5 such investment funds each with a different third partythird-party investor.
The Company consolidates the investment funds, and all inter-company balances and transactions between the Company and the investment funds are eliminated in its condensed consolidated financial statements. The Company determined that the investment funds meet the definition of a VIE.variable interest entity (“VIE”). The Company uses a qualitative approach in assessing the consolidation

requirement for VIEs that focuses on determining whether the Company has the power to direct the activities of the VIE that most significantly affect the VIE’s economic performance and whether the Company has the obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE.
The Company has considered the provisions within the contractual arrangements that grant it power to manage and make decisions that affect the operation of these VIEs, including determining the solar energy systems and associated long term customer contracts to be sold or contributed to the VIEs, and installation, operation and maintenance of the solar energy systems. The Company considers that the rights granted to the other investors under the contractual arrangements are more protective in nature rather than participating rights. As such, the Company has determined it is the primary beneficiary of the

VIEs for all periods presented. The Company evaluates its relationships with VIEs on an ongoing basis to ensure that it continues to be the primary beneficiary.
Under the related agreements, cash distributions of income and other receipts by the funds, net of agreed-upon expenses and estimated expenses, tax benefits and detriments of income and loss, and tax benefits of tax credits, are assigned to the funds’ investor and Company’s subsidiaries as specified in contractual arrangements. Certain of these arrangements have call and put options to acquire the investor’s equity interest as specified in the contractual agreements. See Note 13 for additional information on the call and put options.

Other Variable Interest Entities
The Company follows guidance on the consolidation of VIEs that requires companies to utilize a qualitative approach to determine whether it is the primary beneficiary of a VIE. The process for identifying the primary beneficiary of a VIE requires consideration of the factors that indicate a party has the power to direct the activities that most significantly impact the joint venture'sventures economic performance, including powers granted to the joint venture'sventures program manager, powers contained in the joint venture governing board and, to a certain extent, a company's economic interest in the joint venture. The Company analyzes its joint ventures and classifies them as either:
a VIE that must be consolidated because the Company is the primary beneficiary or the joint venture is not a VIE and the Company holds the majority voting interest with no significant participative rights available to the other partners; or 





3427

AMERESCO, INC.
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) - (Continued)
(in thousands, except per share amounts)


a VIE that does not require consolidation and is treated as an equity method investment because the Company is not the primary beneficiary or the joint venture is not a VIE and the Company does not hold the majority voting interest.

The Company executes certain contracts jointly with third parties through various forms of joint ventures. Although the joint ventures own and hold the contracts with the clients, the services required by the contracts are typically performed by the Company and the Company’s joint venture partners, or by other subcontractors under subcontracting agreements with the joint ventures. Many of these joint ventures are formed for a specific project. The assets of the Company’s joint ventures generally consist almost entirely of cash and land, and the liabilities of our joint ventures generally consist almost entirely of amounts due to the joint venture partners. Many of the joint ventures are deemed to be VIEs because they lack sufficient equity to finance the activities of the joint venture.
In January 2019, the Company entered into a joint venture with one other party to co-own an entity whose purpose is owning and leasing a parcel of land and attached structures to third-party entities. The joint venture has no employees and is controlled by the board of directors made up of representatives from both companies. Prior to January 2019, the Company had determined it was the primary beneficiary of the VIE and fully consolidated the entity. Upon the formation of the joint venture, the Company determined it was no longer the primary beneficiary, based on the assessment of considerations referenced above, and deconsolidated the VIE and recorded the Company’s investment in the joint venture as an equity method investment. With the deconsolidation of the VIE and the recognition of the equity method investment the Company recognized a gain of $2,160 in operating income and recorded an equity method investment of $1,361 in other assets. In addition, the Company has loaned the joint venture $1,506 and made an initial contribution at its formation in exchange for 50% of the shares in the joint venture.
Unconsolidated joint ventures are accounted for under the equity method. For those joint ventures, the Company's investment balances for the joint venture are included in other assets on the condensed consolidated balance sheetsheets and the Company’s pro rata share of net income or loss is included in operating income. The Company’s investments in equity method joint ventures on the condensed consolidated balance sheets as of March 31, 20192020 and December 31, 20182019 was a net asset of $1,361$1,448 and $0,$1,292, respectively. During the three months ended March 31, 2020 and 2019, the Company recognized no income or expense of $53 and $0, respectively, from equity method joint ventures.

The purchase price for two of the investment funds investors’ interests under the call options is equal to the fair market value of such interest at the time the option is exercised. The purchase price for two of the other two investment funds investor’s interests under the call options is equal to the greater of (i) the fair market value of such interests at the time the option is exercised or (ii) 7% of the investors’ contributed capital balance at the time the option is exercisable. The purchase price for the remaining investment fund investor’s interests under the call options is equal to the greater of (i) the fair market value of such interests at the time the option is exercised or (ii) 5% of the investors’ contributed capital balance at the time the option is exercisable.The call options are exercisable beginning on the date that specified conditions are met for each respective fund. None of the call options are expected to become exercisable prior to 2021.
The purchase price for two of the funds investors’ interests in the investment funds under the put options is the lessor of fair market value at the time the option is exercised and a specified amount, ranging from $659 - $917. The purchase price for the other two of the fundremaining funds investors’ interest in the investment funds under the put options is the sum of (i) the fair market value at the time the option is exercised, and (ii) the closing costs incurred by the investor in connection with the exercise of the put option.The purchase price for the remaining fund investors’ interest in the investment funds under the put options is the lessor of fair market value at the time the option is exercised and the sum of (i) 5% of the investors’ contributed capital balance at the time the option is exercisable, and (ii) the fair market value of any unpaid tax law change losses incurred by the investor in connection with the exercise of the put option. The put options for the investment funds are exercisable beginning on the date that specified conditions are met for each respective fund. The put options are not expected to become exercisable prior to 2022.
Because the put options represents redemption features that are not solely within the control of the Company, the non-controlling interests in these funds are presented outside of permanent equity. Redeemable non-controlling interests are reported using the greater of their carrying value at each reporting date (which is impacted by attribution under the HLBVhypothetical liquidation at book value method) or their estimated redemption value in each reporting period. At both March 31, 20192020 and December 31, 20182019 redeemable non-controlling interests were reported at their carrying value totaling $13,341$31,939 and $14,719,$31,616, respectively, as the carrying value at each reporting period was greater than the estimated redemption value.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations
YouYou should read the following discussion and analysis of our financial condition and results of operations together with our unaudited condensed consolidated financial statements and the related notes thereto included in Part I, Item 1 of this Quarterly Report on Form 10-Q and the audited consolidated financial statements and notes thereto and management’s discussion and analysis of financial condition and results of operations for the year ended December 31, 20182019 included in our Annual Report on Form 10-K for the year ended December 31, 20182019 filed on March 8, 20194, 2020 with the U.S. Securities and Exchange Commission (“SEC”). This Quarterly Report on Form 10-Q contains “forward-looking statements” within the meaning of Section 21E of the Securities Exchange Act of 1934, as amended, or the Exchange Act. Forward looking statements include statements regarding our strategy, future operations, future financial position, future revenues, projected costs, prospects, plans, objectives of management, expected market growth and other characterizations of future events or circumstances. All statements, other than statements of historical fact, including statements that refer to our expectations as to the future growth of our business and associated expenses; our expectations as to revenue generation; the future availability of borrowings under our revolving credit facility; the expected future growth of the market for energy efficiency and renewable energy solutions; our backlog, awarded projects and recurring revenue and the timing of such matters; our expectations as to acquisition activity; the impact of any restructuring; the uses of future earnings; our intention to repurchase shares of our Class A common stock; the expected energy and cost savings of our projects; and the expected energy production capacity of our renewable energy plants; and other characterizations of future events or circumstances are forward-looking statements. TheseCurrently, one of the most significant factors, however, is the potential adverse effect of the current pandemic of the novel coronavirus, or COVID-19, on our financial condition, results of operations, cash flows and performance and the global economy and financial markets. The extent to which COVID-19 impacts us, suppliers, customers, employees and supply chains will depend on future developments, which are highly uncertain and cannot be predicted with confidence, including the scope, severity and duration of the pandemic, the actions taken to contain the pandemic or mitigate its impact, and the direct and indirect economic effects of the pandemic and containment measures, among others. Moreover, you should interpret many of the risks identified in this report, as well as the risks set forth below, as being heightened as a result of the ongoing and numerous adverse impacts of COVID-19. Forward looking statements are often, but not exclusively, identified by the use of words such as “may,” “will,” “expect,” “believe,” “anticipate,” “intend,” “could,” “estimate,” “target,” “project,” “predict” or “continue,” and similar expressions or variations. These forward-looking statements are based on current expectations and assumptions that are subject to risks, uncertainties and other factors that could cause actual results and the timing of certain events to differ materially and adversely from future results expressed or implied by such forward-looking statements. Risks, uncertainties and factors that could cause or contribute to such differences include, but are not limited to, those discussed in the section titled “Risk Factors,” set forth in Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2018.2019 and elsewhere in this Quarterly Report on Form 10-Q. The forward-looking statements in this Quarterly Report on Form 10-Q represent our views as of the date of this Quarterly Report on Form 10-Q. Subsequent events and developments may cause our views to change. However, while we may elect to update these forward-lookingforward looking statements at some point in the future, we have no current intention of doing so and undertake no obligation to do so except to the extent required by applicable law. You should, therefore, not rely on these forward-looking statements as representing our views as of any date subsequent to the date of this Quarterly Report on Form 10-Q.
Overview
Ameresco is a leading provider of energy efficiency solutions for facilities throughout North America and Europe. We provide solutions that enable customers to reduce their energy consumption, lower their operating and maintenance costs and realize environmental benefits. Our comprehensive set of services includes upgrades to a facility’s energy infrastructure and the construction and operation of small-scale renewable energy plants.
In addition to organic growth, strategic acquisitions of complementary businesses and assets have been an important part of our historical development. Since inception, we have completed numerous acquisitions, which have enabled us to broaden our service offerings and expand our geographical reach.
COVID-19 Update
In March 2020, the World Health Organization categorized Coronavirus Disease 2019 (“COVID-19”) as a pandemic, and the President of the United States declared the COVID-19 outbreak a national emergency. We are closely monitoring the impact of the COVID-19 pandemic on all aspects of our business, including how it will impact our suppliers, customers, employees and supply chains. While we did not incur significant disruptions during the three months ended March 31, 2020 from the COVID-19 pandemic, we are unable to predict the impact that the COVID-19 pandemic will have on our financial condition, results of operations and cash flows due to numerous uncertainties. These uncertainties include the scope, severity and duration of the pandemic, the actions taken to contain the pandemic or mitigate its impact and the direct and indirect economic effects of the pandemic and containment measures, among others.


34

Further, the overall impact of COVID-19 on our condensed consolidated results of operations for the three months ended March 31, 2020 was not material. However, the impact that COVID-19 will have on our consolidated results of operations throughout 2020 remains uncertain. We expect to experience delays in our project award conversions and potential construction slowdowns as a result of known shelter-in-place restrictions. We will continue to evaluate the nature and extent of these potential impacts to our business, consolidated results of operations, segment results, liquidity and capital resources.
Effects of Seasonality
We are subject to seasonal fluctuations and construction cycles, particularly in climates that experience colder weather during the winter months, such as the northern United States and Canada, or at educational institutions, where large projects are typically carried out during summer months when their facilities are unoccupied. In addition, government customers, many of which have fiscal years that do not coincide with ours, typically follow annual procurement cycles and appropriate funds on a fiscal-year basis even though contract performance may take more than one year. Further, government contracting cycles can be affected by the timing of, and delays in, the legislative process related to government programs and incentives that help drive demand for energy efficiency and renewable energy projects. As a result, our revenues and operating income in the third and fourth quarter are typically higher, and our revenues and operating income in the first quarter are typically lower, than in other quarters of the year. As a result of such fluctuations, we may occasionally experience declines in revenues or earnings as compared to the immediately preceding quarter, and comparisons of our operating results on a period-to-period basis may not be meaningful.

Our annual and quarterly financial results are also subject to significant fluctuations as a result of other factors, many of which are outside our control. See “Our business is affected by seasonal trends and construction cycles, and these trends and cycles could have an adverse effect on our operating results.” in Item 1A, Risk Factors of our Annual Report on Form 10-K for the year ended December 31, 20182019 (“Annual Report”)., and the risks described in Item 1A. Risk Factors in this Quarterly Report on Form 10-Q.
Backlog and Awarded Projects
Total construction backlog represents projects that are active within our ESPC sales cycle. Our sales cycle begins with the initial contact with the customer and ends, when successful, with a signed contract, also referred to as fully-contracted backlog. Our sales cycle recently has been averaging 18 to 4254 months. Awarded backlog is created when a potential customer awards a project to Ameresco following a request for proposal. Once a project is awarded but not yet contracted, we typically conduct a detailed energy audit to determine the scope of the project as well as identify the savings that may be expected to be generated from upgrading the customer’s energy infrastructure. At this point, we also determine the sub-contractor, what equipment will be used, and assist in arranging for third party financing, as applicable. Recently, awarded projects have been taking an average of 12 to 24 months to result in a signed contract and convert to fully-contracted backlog. It may take longer, however, depending upon the size and complexity of the project. Historically, approximately 90% of our awarded backlog projects have resulted in a signed contract. After the customer and Ameresco agree to the terms of the contract and the contract becomes executed, the project moves to fully-contracted backlog. The contracts reflected in our fully-contracted backlog typically have a construction period of 12 to 36 months and we typically expect to recognize revenue for such contracts over the same period. Fully-contracted backlog begins converting into revenues generated from backlog over time using cost based input methods once construction has commenced. See “We may not recognize all revenues from our backlog or receive all payments anticipated under awarded projects and customer contracts” and “In order to secure contracts for new projects, we typically face a long and variable selling cycle that requires significant resource commitments and requires a long lead time before we realize revenues” in Item 1A, Risk Factors in our Annual Report, and the risks described in Item 1A. Risk Factors in this Quarterly Report on Form 10-K.10-Q.
The overall impact of COVID-19 on our condensed consolidated results of operations for the three months ended March 31, 2020 was not material. However, the impact that COVID-19 will have on our consolidated results of operations throughout 2020 remains uncertain. We expect to experience delays in our project award conversions and potential construction slowdowns as a result of known shelter-in-place restrictions. We will continue to evaluate the nature and extent of these potential impacts to our business, consolidated results of operations, segment results, liquidity and capital resources. See “We may not recognize all revenues from our backlog or receive all payments anticipated under awarded projects and customer contracts” and “In order to secure contracts for new projects, we typically face a long and variable selling cycle that requires significant resource commitments and requires a long lead time before we realize revenues” in Item 1A, Risk Factors in our Annual Report, and the risks described in Item 1A. Risk Factors in this Quarterly Report on Form 10-Q.

Critical Accounting Policies and Estimates
This discussion and analysis of our financial condition and results of operations is based upon our condensed consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these condensed consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, expense and related disclosures. The most significant estimates with regard to these condensed consolidated financial statements relate to our estimates of uninstalled materialsfinal construction contract profit in accordance with accounting for long-term contracts under the revenue recognition requirements of contracts with our customers, allowance for doubtful accounts,credit losses, inventory reserves, realization of project development costs, leases, fair value of derivative financial instruments, leases, accounting for business acquisitions, stock-based awards, impairment of long-lived assets and goodwill, income taxes, self insurance reserves and potential liability in conjunction with certain commitments and contingencies. Actual results could differ from those estimates.
Such estimates and assumptions are based on historical experience and on various other factors that management believes to be reasonable under the circumstances. Estimates and assumptions are made on an ongoing basis, and accordingly, the actual results may differ from these estimates under different assumptions or conditions.
The following are certain critical accounting policies that, among others, affect our more significant judgments and estimates used in the preparation of our condensed consolidated financial statements:

Revenue Recognition;
Energy Assets;
Leases;
Goodwill and Intangible Assets;
Derivative Financial Instruments; and
Variable Interest Entities.
Further details regarding our critical accounting policies and estimates can be found in Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations” of our Annual Report. In addition, please refer to Note 2, “Summary of Significant Accounting Policies,” of our Notes to Condensed Consolidated Financial Statementsthe audited consolidated financial statements for the year ended December 31, 2019, and notes thereto, included under Part I, Item 1 of this Quarterly Report on Form 10-Q. Except for accounting policies related to our adoption of ASC 842, Managementin the Company’s Annual Report. The Company has determined that no material changes concerning our critical accounting policies have occurred since December 31, 2018.2019.

Unallocated corporate activity includes all corporate level selling, general and administrative expenses and other expenses not allocated to the segments. We do not allocate any indirect expenses to the segments.
Liquidity and Capital Resources
Sources of liquidity. Since inception, we have funded operations primarily through cash flow from operations, advances from Federal ESPC projects and various forms of debt. We believe that the cash and cash equivalents and availability under our revolving senior secured credit facility, combined with our access to credit markets, will be sufficient to fund our operations through the next twelve months and thereafter. See Note 2 of the audited consolidated financial statements for the year ended December 31, 2019, and notes thereto, included in the Company’s Annual Report.
We believe we have sufficient liquidity to satisfy our cash needs, however, we continue to evaluate and take action, as necessary, to preserve adequate liquidity and ensure that our business can continue to operate during these uncertain times. This includes limiting discretionary spending across the organization and re-prioritizing our capital projects amid the COVID-19 pandemic.

On March 27, 2020, the U.S. government enacted the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) which includes modifications to the limitation on business interest expense and net operating loss provisions, and provides a payment delay of employer payroll taxes during 2020 after the date of enactment. We estimate the payment of approximately $5.0 million of employer payroll taxes otherwise due in 2020 will be delayed with 50% due by December 31, 2021 and the remaining 50% by December 31, 2022.

Proceeds from our Federal ESPC projects are generally received through agreements to sell the ESPC receivables related to certain ESPC contracts to third-party investors. We use the advances from the investors under these agreements to finance the projects. Until recourse to us ceases for the ESPC receivables transferred to the investor, upon final acceptance of the work


by the government customer, we are the primary obligor for financing received. The transfers of receivables under these agreements do not qualify for sales accounting until final customer acceptance of the work, so the advances from the investors are not classified as operating cash flows. Cash draws that we receive under these ESPC agreements are recorded as financing cash inflows. The use of the cash received under these arrangements to pay project costs is classified as operating cash flows. Due to the manner in which the ESPC contracts with the third-party investors are structured, our reported operating cash flows are materially impacted by the fact that operating cash flows only reflect the ESPC contract expenditure outflows and do not reflect any inflows from the corresponding contract revenues. Upon acceptance of the project by the federal customer the ESPC receivable and corresponding ESPC liability are removed from our condensed consolidated balance sheet as a non-cash settlement. See Note 2, Summary of Significant Accounting Policies, to our Notes to Condensed Consolidated Financial Statements appearing in Part I, Item 1 of this Quarterly Report on Form 10-Q.
Our service offering also includes the development, construction and operation of small-scale renewable energy plants. Small-scale renewable energy projects, or energy assets, can either be developed for the portfolio of assets that we own and operate or designed and built for customers. Expenditures related to projects that we own are recorded as cash outflows from investing activities. Expenditures related to projects that we build for customers are recorded as cash outflows from operating activities as cost of revenues.
The amount of interest capitalized relating to construction financing during the period of construction for the three months ended March 31, 2020 and 2019 was $0.9 million and 2018 was $0.8 million, and $1.0 million, respectively.
Cash flows from operating activities. Operating activities used $51.6 million of net cash during the three months ended March 31, 2020.

PART II - OTHER INFORMATION
Item 1. Legal Proceedings
In the ordinary conduct of our business we are subject to periodic lawsuits, investigations and claims. Although we cannot predict with certainty the ultimate resolution of such lawsuits, investigations and claims against us, we do not believe that any currently pending or threatened legal proceedings to which we are a party will have a material adverse effect on our business, results of operations or financial condition.
For additional information about certain proceedings, please refer to Note 9, Commitments and Contingencies, to our Condensed Consolidated Financial Statements included included under Part I, Item 1 of this Quarterly Report on Form 10-Q, which is incorporated into this item by reference.

Item 1A. Risk Factors
AsOur business is subject to numerous risks, a number of March 31, 2019, there have been no material changes to the risk factorswhich are described below and under “Risk Factors” in Item 1A toPart I of our Annual Report on Form 10-K for the year ended December 31, 2018.2019 (“Annual Report”). We caution you that the following important factors, among others, could cause our actual results to differ materially from those expressed in forward-looking statements made by us or on our behalf in filings with the SEC, press releases, communications with investors and oral statements. Any or all of our forward-looking statements in this Quarterly Report on Form 10-Q and in any other public statements we make may turn out to be wrong. They can be affected by inaccurate assumptions we might make or by known or unknown risks and uncertainties. Many factors mentioned in the discussion below and in our Annual Report will be important in determining future results. Consequently, no forward-looking statement can be guaranteed. Actual future results may differ materially from those anticipated in forward-looking statements. We undertake no obligation to update any forward-looking statements, whether as a result of new information, future events or otherwise, except to the extent required by applicable law. You should, however, consult any further disclosure we make in our reports filed with the SEC.

Public health threats or outbreaks of communicable diseases could have a material adverse effect on our operations and financial results.

We may face risks related to public health threats or outbreaks of communicable diseases. A widespread healthcare crisis, such as an outbreak of a communicable disease could adversely affect the global economy our ability to conduct business for an indefinite period of time. For example, the ongoing global Coronavirus Disease 2019 (COVID-19) pandemic, has negatively impacted global economy, disrupted financial markets and international trade, resulted in increased unemployment levels and significantly impacted global supply chains. In addition, Federal, state, and local governments have implemented various mitigation measures, including travel restrictions, border closings, restrictions on public gatherings, shelter-in-place restrictions and limitations on business. Although we are considered an essential business, some of these actions have adversely impacted the ability of our employees, contractors, suppliers, customers, and other business partners to conduct business activities, and could ultimately do so for an indefinite period of time. The COVID-19 impacts described above could have a material adverse effect on our results of operations, financial condition, and liquidity. In particular, the continued spread of COVID-19 and efforts to contain the virus could:
impact the length of our sales cycle;
cause us to experience an increase in delayed payments from customers and uncollectable accounts;
cause delays and disruptions in the completion of certain projects;
impact availability of qualified personnel; and
cause other unpredictable events.
The situation surrounding COVID-19 remains fluid and the potential for a material impact on our results of operations, financial condition, and liquidity increases the longer the virus impacts activity levels in the United States and globally. For this reason, we cannot reasonably estimate with any degree of certainty the future impact COVID-19 may have on our results of operations, financial position, and liquidity. The extent to which the COVID-19 pandemic may impact our business, operating results, financial condition, or liquidity will depend on future developments, including the duration of the outbreak, travel restrictions, business and workforce disruptions, and the effectiveness of actions taken to contain and treat the disease.

Due to the COVID-19 pandemic, we have experienced a lengthening of our selling cycle and, if this slowdown continues, the timeline for realizing revenue on new projects may be further delayed.

Historically, the sales, design and construction process for energy efficiency and renewable energy projects recently has been taking from 18 to 54 months on average, with sales to federal government and housing authority customers tending to require the longest sales processes. We have been experiencing a lengthening of our sales cycle as a result of the impacts of the COVID-19 pandemic, as customers move to adjust operations and conserve cash. We cannot predict the timeline of the COVID-19 pandemic and, therefore, cannot predict the timeline for our selling cycle in the current conditions. Our sales process continues to require the dedication of significant time by our sales and management personnel and our use of significant financial resources, with no certainty of success or recovery of our related expenses. A potential customer may go through the entire sales process and not accept our proposal. All of these factors can contribute to fluctuations in our quarterly financial performance and increase the likelihood that our operating results in a particular quarter will fall below investor expectations. These factors could also adversely affect our business, financial condition and operating results due to increased spending by us that is not offset by increased revenues.

We may be unable to complete or operate our projects on a profitable basis or as we have committed to our customers.
Development, installation and construction of our energy efficiency and renewable energy projects, and operation of our renewable energy projects, entails many risks, including:
failure to receive critical components and equipment that meet our design specifications and can be delivered on schedule;
failure to obtain all necessary rights to land access and use;
failure to receive quality and timely performance of third-party services;
increases in the cost of labor, equipment and commodities needed to construct or operate projects;
permitting and other regulatory issues, license revocation and changes in legal requirements;
shortages of equipment or skilled labor;
unforeseen engineering problems;
failure of a customer to accept or pay for renewable energy that we supply;
weather interferences, catastrophic events including fires, explosions, earthquakes, droughts and acts of terrorism; and accidents involving personal injury or the loss of life;
health or similar issues, such as a pandemic or epidemic, such as the novel coronavirus (COVID-19);
labor disputes and work stoppages;
mishandling of hazardous substances and waste; and
other events outside of our control.
Any of these factors could give rise to construction delays and construction and other costs in excess of our expectations. This could prevent us from completing construction of our projects, cause defaults under our financing agreements or under contracts that require completion of project construction by a certain time, cause projects to be unprofitable for us, or otherwise impair our business, financial condition and operating results.

We may have exposure to additional tax liabilities and our effective tax rate may increase or fluctuate, which could increase our income tax expense and reduce our net income.
Our provision for income taxes is subject to volatility and could be adversely affected by changes in tax laws or regulations, particularly changes in tax incentives in support of energy efficiency. For example, certain deductions relating to energy efficiency have expiration dates which could significantly alter the existing tax code, including the removal of these credits prior to their scheduled expiration. The 30% investment tax credit (“ITC”) relating to the installation of solar power expired on December 31, 2019, after which it will fall to 26 percent in 2020, 22 percent in 2021, and 10 percent in 2022 and future years. If these or other deductions and credits expire without being extended, or otherwise are reduced or eliminated, our effective tax rate would increase, which could increase our income tax expense and reduce our net income.
Our tax rate has historically been significantly impacted by the IRC Section 179D deduction. This deduction is related to energy efficient improvements we provide under government contracts. Section 179D was extended through December 31, 2020 as part of the Tax Extender and Disaster Relief Act of 2019 which became law on December 20, 2019. There is no


44

Table of Contents

assurance that Section 179D will continue to be extended retroactively or otherwise and were the deduction not available it would significantly affect our tax rate.
More recently, on March 18, 2020, the Families First Coronavirus Response Act (“FFCR Act”), and on March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) were each enacted in response to the COVID-19 pandemic. The FFCR Act and the CARES Act contain numerous income tax provisions, such as relaxing limitations on the deductibility of interest and the use of net operating losses arising in taxable years beginning after December 31, 2017. We are currently evaluating the impact of this legislation on our consolidated financial position, results of operations, and cash flows. Future regulatory guidance under the FFCR Act and the CARES Act remains forthcoming, and such guidance could ultimately increase or lessen their impact on our business and financial condition. It is also highly possible that Congress will enact additional legislation in connection with the COVID-19 pandemic, some of which could have an impact on us.
The determination of the benefit from (or provision for) income taxes requires complex estimations and significant judgments concerning the applicable tax laws. If in the future any element of tax legislation changes the related accounting guidance for income tax, it could affect our income tax position and we may need to adjust the benefit from (or provision for) income taxes accordingly.
In addition, like other companies, we may be subject to examination of our income tax returns by the U.S. Internal Revenue Service and other tax authorities; our U.S. federal tax returns for 2015 through 2018 are subject to audit by federal, state and foreign tax authorities. Though we regularly assess the likelihood of adverse outcomes from such examinations and the adequacy of our provision for income taxes, there can be no assurance that such provision is sufficient and that a determination by a tax authority will not have an adverse effect on our net income.
A substantial portion of our earnings are derived from the sale of renewable energy certificates (“RECs”) and other environmental attributes, and our failure to be able to sell such attributes could materially adversely affect our business, financial condition and results of operation.
A substantial portion of our earnings are attributable to our sale of renewable energy certificates (“RECs”) and other environmental attributes generated by our energy assets. These attributes are used as compliance purposes for state-specific or U.S. federal policy.
We own and operate solar PV installations which derive a significant portion of their revenues from the sale of solar renewable energy certificates (“SRECs”), which are produced as a result of generating electricity. The value of these SRECs is determined by the supply and demand of SRECs in the states in which the solar PV installations are installed. Supply is driven by the amount of installations and demand is driven by state-specific laws relating to renewable portfolio standards.
We also own and operate renewable natural gas plants that may deliver biofuels into to the nation’s natural gas pipeline grid. Such biofuel may qualify for certain environmental attribute mechanisms, such as renewable identification numbers (“RINs”) which are used for compliance purposes under the Renewable Fuel Standard (“RFS”) program. The RFS is a U.S. federal policy that requires transportation fuel to contain a minimum volume of renewable fuel. The U.S. Environmental Protection Agency (“EPA”) administers the RFS program and may periodically undertake regulatory action involving the RFS, including annual volume standards for renewable fuel.
We sometimes seek to sell forward a portion of our SRECs and other environmental attributes under contracts to fix the revenues from those attributes for financing purposes or hedge against future declines in prices of such environmental attributes. If our renewable energy facilities do not generate the amount of renewable energy attributes sold under such forward contracts or if for any reason the renewable energy we generate does not produce SRECs or other environmental attributes for a particular state, we may be required to make up the shortfall of SRECs or other environmental attributes under such forward contracts through purchases on the open market or make payments of liquidated damages.
RECs are created through state law requirements for utilities to purchase a portion of their energy from renewable energy sources and changes in state laws or regulation relating to RECs may adversely affect the availability of RECs or other environmental attributes and the future prices for RECs or other environmental attributes, which could have an adverse effect on our business, financial condition and results of operations.
The market price for renewable energy attributes fluctuates based on a variety of factors including, but not limited to, governmental and regulatory action, perceptions concerning the prospect for changes in the renewable fuels standards or renewable portfolio standards, the future supply of tradable environmental attributes, and other market dynamics. In particular, during the current COVID-19 pandemic, as restrictions on travel continue and there has been lower electricity and fuel


45

Table of Contents

consumption, we have observed increased volatility in the market prices for these renewable energy attributes, as well as price reductions in certain markets. As a result, we may not be able to sell our renewable energy attributes at a price that is favorable to us. Any significant or sustained decline in the market price of renewable energy attributes could have a material adverse effect on our business, financial condition and results of operations.
