ORGANIZATION AND OPERATIONS OF THE COMPANY
ORGANIZATION AND OPERATIONS OF THE COMPANY	1. ORGANIZATION AND OPERATIONS OF THE COMPAN Willdan Group, Inc. (“Willdan” or the “Company”) is a provider of professional, technical and consulting services to utilities, private industry, and public agencies at all levels of government. As resources and infrastructures undergo continuous change, the Company helps organizations and their communities evolve and thrive by providing a wide range of technical services for energy solutions and government infrastructure. Through engineering, program management, policy advisory, and software and data management, the Company designs and delivers trusted, comprehensive, innovative, and proven solutions to improve efficiency, resiliency, and sustainability in energy and infrastructure . The Company’s broad portfolio of services operates within two financial reporting segments: (1) Energy and (2) Engineering and Consulting. The interfaces and synergies between these segments are important elements of the Company’s strategy to design and deliver trusted, comprehensive, innovative, and proven solutions for its customers The accounting policies followed by the Company are set forth in Part II, Item 8, Note 1, Organization and Operations of the Company , of the Notes to Consolidated Financial Statements included in the Company’s Annual Report on Form 10‑K for the fiscal year ended December 27, 2019. In the opinion of management, all adjustments necessary to fairly state the Condensed Consolidated Financial Statements have been made. All such adjustments are of a normal, recurring nature. Certain information and footnote disclosures normally included in the Consolidated Financial Statements prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). These Condensed Consolidated Financial Statements and related notes thereto should be read in conjunction with the Consolidated Financial Statements and the notes thereto included in the Company’s Annual Report on Form 10‑K for the fiscal year ended December 27, 2019. The results of operations for interim periods are not necessarily indicative of results to be expected for the full year. Fiscal Years The Company operates and reports its annual financial results based on 52 or 53-week periods ending on the Friday closest to December 31. The Company operates and reports its quarterly financial results based on the 13-week period ending on the Friday closest to March 31, June 30 and September 30 and the 13 or 14-week period ending on the Friday closest to December 31, as applicable. Fiscal years 2019, 2018 and 2017 contained 52 weeks. All references to years in the notes to consolidated financial statements represent fiscal years. Use of Estimates The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements. Estimates also affect the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. Management’s Plans in Response to Covid-19 On January 30, 2020, the spread of a novel strain of coronavirus (“Covid-19”) was declared a Public Health Emergency of International Concern by the World Health Organization (“WHO”). On March 11, 2020, WHO characterized the Covid-19 outbreak as a pandemic. The Covid-19 pandemic has resulted in governmental authorities around the world implementing numerous measures to try to contain the virus, such as travel bans and restrictions, quarantines, shelter-in-place or total lock-down orders and business limitations and shutdowns (subject to exceptions for certain essential operations and businesses). The Covid-19 outbreak and restrictions intended to slow the spread of Covid-19 have caused economic and social disruption on an unprecedented scale. It is unclear how long these restrictions will remain in place and they may remain in place in some form for an extended period of time. Given the uncertainties associated with the duration of the pandemic, the Company cannot reasonably estimate the ultimate impacts of Covid-19 and efforts to limit its spread on its business, financial condition, results of operations or cash flows for the foreseeable future or whether the Company’s assumptions used to estimate its future liquidity requirements will be correct . Health and Safety In response to the Covid-19 pandemic, the Company has taken and will continue to take temporary precautionary measures intended to help minimize the risk of Covid-19 to its employees, including requiring the majority of its employees to work remotely, suspending non-essential travel and restricting in-person work-related meetings. The Company expects to continue to implement these measures until it has determined that the Covid-19 pandemic is adequately contained for purposes of its business, and may take further actions as government authorities require or recommend or as it determines to be in the best interests of its employees, customers, business partners and third-party service providers. Financial Position and Results of Operations The Covid-19 pandemic and efforts to limit its spread negatively impacted the Company’s operations during the three months ended April 3, 2020. In California and New York, the states in which it has historically derived a majority of its revenue, mandatory shutdown orders were issued in March. As such, Covid-19 had only a partial impact on the Company’s operations during its first fiscal quarter of 2020 and it expects the impact to be more significant in its second quarter. In the Energy segment, the Company has experienced and expects to continue to experience a negative impact on its direct install programs that serve small businesses as a result of restrictions put in place by governmental authorities that have required temporary shutdowns of all “non-essential” businesses. In fiscal 2019, the Company derived approximately 40% of its gross Energy segment revenue from its direct install programs that serve small businesses, and a significant portion of its direct install work on these programs is currently suspended and will remain suspended until Covid-19-related restrictions are lifted. The Company’s other energy programs, which generated approximately 60% of its gross Energy segment revenue in fiscal 2019, are either direct install work for small businesses that have been determined to be “essential” by government authorities or has continued to progress during the pandemic. In addition, some of the Company’s programs in the Energy segment, including certain programs in New York, are considered “essential” under applicable governmental regulations are being accelerated because of their importance to help fight this pandemic In the Engineering and Consulting segment, the Company’s revenues have been minimally affected. The services in this segment have generally been deemed “essential” by the government and have continued to operate while abiding social distancing measures. As of May 8, 2020, though some of the Company work has been suspended, none of its contracts have been cancelled. In response to the Covid-19 pandemic and efforts to prevent its spread, the Company began taking a number of steps during the first quarter of fiscal 2020 aimed at preserving liquidity and positioning itself to resume its growth trajectory after work restrictions are lifted. These steps include: · Executing a reduction in workforce, primarily through an unpaid furlough, impacting approximately 300 members of staff. The largest reductions were a result of government-mandated work restrictions impacting the Company’s direct install programs in California and New York; · A temporary freeze on all non-critical spending for travel, capital expenditures, and other discretionary expenses; · A temporary cash wage reduction for salaried employees, ranging from 0% for lower salary bands up to 75% for senior management; · Suspension of cash fees for the Company’s Board of Directors, until such time as the Board of Directors determines; · Implementing a temporary hiring freeze; and · Amending the Company’s credit facility for increased flexibility. The Company believes that its financial position will allow it to withstand the current economic environment. In the first quarter of fiscal year 2020, the Company enhanced liquidity by minimizing working capital and improving cash collections and, in May 2020, the Company amended its credit facilities to amend certain covenants to increase its financial flexibility. Combined with availability under its credit facilities, the Company believes its enhanced liquidity position provides a cushion against any unforeseen liquidity disruptions. The Company anticipates borrowing additional amounts under its existing credit facility during the second half of fiscal year 2020. Asset and liability valuation and other estimates used in preparation of financial statements As of April 3, 2020, the Company did not have any impairment with respect to goodwill or long-lived assets, including intangible assets. Because the full extent of the impact of the Covid-19 outbreak and efforts to slow its spread are unknown at this time, they could, under certain circumstances, cause impairment and result in a non-cash impairment charge being recorded in future periods. Changes to the estimated future profitability of the business may require that the Company establish an additional valuation allowance against all or some portion of its net deferred tax assets. Impact on Clients and Subcontractors and Other Risks The Company primarily works for utilities, municipalities and other public agencies. The Company expects many governmental and other public agencies will have significant budget shortfalls for 2020 and potentially beyond as a result of the economic slowdown from the measures taken to mitigate the Covid-19 pandemic. These potential budget deficits could result in delayed funding for existing contracts with the Company, postponements of new contracts or price concessions. Further, most of the Company’s clients are not committed to purchase any minimum amount of services, as the Company agreements with them are based on a “purchase order” model. As a result, they may discontinue utilizing some or all of the Company’s services with little or no notice. In addition, the Company relies on subcontractors to complete a substantial portion of our work, especially in its Energy segment. If the Company’s preferred subcontractors suffer significant economic harm and must limit or cease operations or file for bankruptcy as a result of the current economic slowdown, the Company’s subcontractors may not be able to fulfill their contractual obligations satisfactorily and the Company may not have the ability to select its subcontractors of choice for new contracts. If the Company’s subcontractors are not able to fulfill their contractual obligations, it could result in a significant increase in costs for the Company to complete the projects. The ultimate impact of Covid-19 on the Company’s financial condition and results of operations will depend on all of the factors noted above, including other factors that the Company may not be able to forecast at this time. See the risk factor “ The Covid-19 pandemic and health and safety measures intended to slow its spread have adversely affected, and may continue to adversely affect, our business, results of operations and financial condition.” under Part II. Item 1A. of this Quarterly Report on Form 10-Q. While the Company expects the impacts of Covid-19 to have an adverse effect on its business, financial condition and results of operations, it is unable to predict the extent of these impacts at this time.

RECENT ACCOUNTING PRONOUNCEMENTS
RECENT ACCOUNTING PRONOUNCEMENTS	2. RECENT ACCOUNTING PRONOUNCEMENTS Accounting Pronouncements Recently Adopted In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”). ASU 2016-13 requires entities to report “expected” credit losses on financial instruments and other commitments to extend credit rather than the current “incurred loss” model. These expected credit losses for financial assets held at the reporting date are to be based on historical experience, current conditions, and reasonable and supportable forecasts. ASU 2016-13 will also require enhanced disclosures relating to significant estimates and judgments used in estimating credit losses, as well as the credit quality. The Company adopted this standard effective December 28, 2019. The adoption of this standard did not have a material impact on the Company’s Condensed Consolidated Financial Statements Accounting Pronouncements Recently Issued In December 2019, the FASB issued ASU No. 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes” (“ASU 2019-12”). ASU 2019-12 amends the accounting for income taxes by, among other things, removing: (i) The exception to the incremental approach for intraperiod tax allocation when there is a loss from continuing operations and income or a gain from other items (for example, discontinued operations or other comprehensive income); (ii) The exception to the requirement to recognize a deferred tax liability for equity method investments when a foreign subsidiary becomes an equity method investment; (iii) The exception to the ability not to recognize a deferred tax liability for a foreign subsidiary when a foreign equity method investment becomes a subsidiary; and (iv) The exception to the general methodology for calculating income taxes in an interim period when a year-to-date loss exceeds the anticipated loss for the year. The amendments are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020, which for the Company is the first quarter of fiscal 2021. The Company is currently evaluating the impact this update will have on its Condensed Consolidated Financial Statements.

REVENUES

REVENUES..
REVENUES	3. REVENUES The Company enters into contracts with its clients that contain various types of pricing provisions, including fixed price, time-and-materials, and unit-based provisions. The Company recognizes revenues in accordance with ASU 2014-09, Revenue from Contracts with Customer, codified as ASC Topic 606 and the related amendments (collectively “ASC 606”). As such, the Company identifies a contract with a customer, identifies the performance obligations in the contract, determines the transaction price, allocates the transaction price to each performance obligation in the contract and recognizes revenues when (or as) the Company satisfies a performance obligation. The following table reflects the Company’s two reportable segments and the types of contracts that each most commonly enters into for revenue generating activities. Segment Contract Type Revenue Recognition Method Time-and-materials Time-and-materials Energy Unit-based Unit-based Software license Unit-based Fixed price Percentage-of-completion Time-and-materials Time-and-materials Engineering and Consulting Unit-based Unit-based Fixed price Percentage-of-completion Revenue on the vast majority of the Company’s contracts is recognized over time because of the continuous transfer of control to the customer. Revenue on fixed price contracts is recognized on the percentage-of-completion method based generally on the ratio of direct costs incurred-to-date to estimated total direct costs at completion. The Company uses the percentage-of-completion method to better match the level of work performed at a certain point in time in relation to the effort that will be required to complete a project. In addition, the percentage-of-completion method is a common method of revenue recognition in the Company’s industry. Many of the Company’s fixed price contracts involve a high degree of subcontracted fixed price effort and are relatively short in duration, thereby lowering the risks of not properly estimating the percent complete. Revenue on time-and-materials and unit-based contracts is recognized as the work is performed in accordance with the specific rates and terms of the contract. The Company recognizes revenues for time-and-materials contracts based upon the actual hours incurred during a reporting period at contractually agreed upon rates per hour and also includes in revenue all reimbursable costs incurred during a reporting period. Certain of the Company’s time-and-materials contracts are subject to maximum contract values and, accordingly, when revenue is expected to exceed the maximum contract value, these contracts are generally recognized under the percentage-of-completion method, consistent with fixed price contracts. For unit-based contracts, the Company recognizes the contract price of units of a basic production product as revenue when the production product is delivered during a period. Revenue recognition for software licenses issued by the Energy segment is generally recognized at a point in time, utilizing the unit-based revenue recognition method, upon acceptance of the software by the customer and in recognition of the fulfillment of the performance obligation. Certain additional performance obligations beyond the base software license may be separated from the gross license fee and recognized on a straight-line basis over time. Revenue for amounts that have been billed but not earned is deferred, and such deferred revenue is referred to as contract liabilities in the accompanying condensed consolidated balance sheets. To determine the proper revenue recognition method for contracts, the Company evaluates whether two or more contracts should be combined and accounted for as one single contract and whether the combined contract should be accounted for as one performance obligation. With respect to the Company’s contracts, it is rare that multiple contracts should be combined into a single performance obligation. This evaluation requires significant judgment and the decision to combine a group of contracts or separate a single contract into multiple performance obligations could change the amount of revenue and profit recorded in a given period. Contracts are considered to have a single performance obligation if the promise to transfer the individual goods or services is not separately identifiable from other promises in the contracts, which is mainly because the Company provides a significant service of integrating a complex set of tasks and components into a single project or capability. The Company may enter into contracts that include separate phases or elements. If each phase or element is negotiated separately based on the technical resources required and/or the supply and demand for the services being provided, the Company evaluates if the contracts should be segmented. If certain criteria are met, the contracts would be segmented which could result in revenues being assigned to the different elements or phases with different rates of profitability based on the relative value of each element or phase to the estimated total contract revenue. Segmented contracts may comprise up to approximately 2.0% to 3.0% of the Company’s consolidated contract revenue. Contracts that cover multiple phases or elements of the project or service lifecycle (development, construction and maintenance and support) may be considered to have multiple performance obligations even when they are part of a single contract. For contracts with multiple performance obligations, the Company allocates the transaction price to each performance obligation using the best estimate of the standalone selling price of each distinct good or service in the contract. For the periods presented, the value of the separate performance obligations under contracts with multiple performance obligations (generally measurement and verification tasks under certain energy performance contracts) were not material. In cases where the Company does not provide the distinct good or service on a standalone basis, the primary method used to estimate standalone selling price is the expected cost plus a margin approach, under which the Company forecasts the Company’s expected costs of satisfying a performance obligation and then adds an appropriate margin for the distinct good or service. The Company provides quality of workmanship warranties to customers that are included in the sale and are not priced or sold separately or do not provide customers with a service in addition to assurance of compliance with agreed-upon specifications and industry standards. The Company does not consider these types of warranties to be separate performance obligations. In some cases, the Company has a master service or blanket agreement with a customer under which each task order releases the Company to perform specific portions of the overall scope in the service contract. Each task order is typically accounted for as a separate contract because the task order establishes the enforceable rights and obligations, and payment terms. Under ASC 606, variable consideration should be considered when determining the transaction price and estimates should be made for the variable consideration component of the transaction price, as well as assessing whether an estimate of variable consideration is constrained. For certain of the Company’s contracts, variable consideration can arise from modifications to the scope of services resulting from unapproved change orders or customer claims. Variable consideration is included in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. The Company estimates of variable consideration and determination of whether to include estimated amounts in the transaction price are based largely on assessments of legal enforceability, the Company’s performance, and all information (historical, current and forecasted) that is reasonably available to the Company. Due to the nature of the work required to be performed on many of the Company’s performance obligations, the estimation of total revenue and cost at completion is complex, subject to many variables and requires significant judgment. As a significant change in one or more of these estimates could affect the profitability of the Company’s contracts, the Company reviews and updates the Company’s contract-related estimates regularly through a company-wide disciplined project review process in which management reviews the progress and execution of the Company’s performance obligations and the estimate at completion (EAC). As part of this process, management reviews information including, but not limited to, any outstanding key contract matters, progress towards completion and the related program schedule and the related changes in estimates of revenues and costs. Management must make assumptions and estimates regarding labor productivity and availability, the complexity of the work to be performed, the cost and availability of materials, the performance of subcontractors, and the availability and timing of funding from the customer, among other variables. The Company recognizes adjustments in estimated profit on contracts under the cumulative catch-up method. Under this method, the impact of the adjustment on profit recorded to date is recognized in the period the adjustment is identified. Revenue and profit in future periods of contract performance is recognized using the adjusted estimate. If at any time the estimate of contract profitability indicates an anticipated loss on the contract, the Company recognizes the full amount of estimated loss in the period it is identified. Contracts are often modified to account for changes in contract specifications and requirements. The Company considers contract modifications to exist when the modification either creates new rights or obligations or changes the existing enforceable rights or obligations. Most of the Company’s contract modifications are for goods or services that are not distinct from existing contracts due to the significant integration provided in the context of the contract and are accounted for as if they were part of the original contract. The effect of a contract modification that is not distinct from the existing contract on the transaction price and the Company’s measure of progress for the performance obligation to which it relates is recognized as an adjustment to revenue (either as an increase in or a reduction of revenue) on a cumulative catch-up basis. For contract modifications that result in the promise to deliver goods or services that are distinct from the existing contract and the increase in price of the contract is for the same amount as the standalone selling price of the additional goods or services included in the modification, the Company accounts for such contract modifications as a separate contract. The Company includes claims to vendors, subcontractors and others as a receivable and a reduction in recognized costs when enforceability of the claim is established by the contract and the amounts are reasonably estimable and probable of being recovered. The amounts are recorded up to the extent of the lesser of the amounts management expects to recover or to costs incurred. Billing practices are governed by the contract terms of each project based upon costs incurred, achievement of milestones or pre-agreed schedules. Billings do not necessarily correlate with revenue recognized using the percentage-of-completion method of revenue recognition. Direct costs of contract revenue consist primarily of that portion of technical and nontechnical salaries and wages that has been incurred in connection with revenue producing projects. Direct costs of contract revenue also include production expenses, subcontractor services and other expenses that are incurred in connection with revenue producing projects. Direct costs of contract revenue exclude that portion of technical and nontechnical salaries and wages related to marketing efforts, vacations, holidays and other time not spent directly generating revenue under existing contracts. Such costs are included in general and administrative expenses. Additionally, payroll taxes, bonuses and employee benefit costs for all Company personnel are included in general and administrative expenses in the accompanying consolidated statements of comprehensive income since no allocation of these costs is made to direct costs of contract revenue. No allocation of facilities costs is made to direct costs of contract revenue. Other companies may classify as direct costs of contract revenue some of the costs that the Company classifies as general and administrative costs. The Company expenses direct costs of contract revenue when incurred. Included in revenue and costs are all reimbursable costs for which the Company has the risk or on which the fee was based at the time of bid or negotiation. No revenue or cost is recorded for costs in which the Company acts solely in the capacity of an agent and has no risks associated with such costs. Accounts receivable are carried at original invoice amount less an estimate made for doubtful accounts based upon a review of all outstanding amounts on a quarterly basis. Management determines allowances for doubtful accounts through specific identification of amounts considered to be uncollectible and potential write-offs, plus a non-specific allowance for other amounts for which some potential loss has been determined to be probable based on current and past experience. The Company’s historical credit losses have been minimal with governmental entities and large public utilities, but disputes may arise related to these receivable amounts. Accounts receivable are written off when deemed uncollectible. Recoveries of accounts receivable previously written off are recorded when received. Retainage, included in contract assets, represents amounts withheld from billings to the Company’s clients pursuant to provisions in the contracts and may not be paid to the Company until specific tasks are completed or the project is completed and, in some instances, for even longer periods. At April 3, 2020 and December 27, 2019, contract assets included retainage of approximately $4.4 million and $5.4 million, respectively. In addition to the above, the Company derives revenue from software licenses and professional services and maintenance fees. In accordance with ASC 606, the Company performs an assessment of each contract to identify the performance obligations, determine the overall transaction price for the contract, allocate the transaction price to the performance obligations, and recognize the revenue when the performance obligations are satisfied. The Company utilizes the residual approach by which it estimates the standalone selling price by reference to the total transaction price less the sum of the observable standalone selling prices of other goods or services promised in the contract.

DERIVATIVE FINANCIAL INSTRUMENTS
DERIVATIVE FINANCIAL INSTRUMENTS	5. DERIVATIVE FINANCIAL INSTRUMENTS The Company uses certain interest rate derivative contracts to hedge interest rate exposures on its variable rate debt. The Company’s hedging program is not designated for trading or speculative purposes. The Company recognizes derivative instruments as either assets or liabilities on the accompanying consolidated balance sheets at fair value. The Company records changes in the fair value (i.e., gains or losses) of the derivatives that have been designated as cash flow hedges in its consolidated balance sheets as accumulated other comprehensive income (loss) and in its condensed consolidated statements of comprehensive (loss) income as a loss or gain on cash flow hedge valuation. On January 31, 2019, the Company entered into an interest rate swap agreement that the Company designated as cash flow hedge to fix the variable interest rate on a portion of the Company’s Term A Loan (as defined below in Note 6. “ Debt Obligations ”). The interest rate swap agreement total notional amount of $35.0 million, has a fixed annual interest rate of 2.47% and expires on January 31, 2022. As of April 3, 2020, the effective portion of the Company’s interest rate swap agreement designated as a cash flow hedge before tax effects was $1.0 million, of which no amounts were reclassified from accumulated other comprehensive income to interest expense in the three months ended April 3, 2020. The Company expects to reclassify $0.6 million from accumulated other comprehensive loss to interest expense within the next twelve months. The fair values of the Company’s outstanding derivatives designated as hedging instruments were as follows: Fair Value of Derivative Instruments as of Balance Sheet Location April 3, 2020 December 27, 2019 (in thousands) Interest rate swap agreement Accrued liabilities $ (624) $ (241) Interest rate swap agreement Other noncurrent (liabilities) assets $ (490) $ (306) The impact of the effective portions of derivative instruments in cash flow hedging relationships and fair value relationships on other comprehensive income were $0.4 and $0.2 million of the fiscal three months ended April 3, 2020 and March 29, 2019, respectively.

The Credit Agreement provides for (i) a $100.0 million secured term loan (the “Term A Loan”), (ii) up to $50.0 million in delayed draw secured term loans (the “Delayed Draw Term Loan”), and (iii) a $50.0 million secured revolving credit facility (the “Revolving Credit Facility” and, collectively with the Term A Loan and the Delayed Draw Term Loan, the “Credit Facilities”), each maturing on June 26, 2024. The Company’s obligations under the Credit Agreement are guaranteed by its present and future domestic subsidiaries, with limited exceptions. The Credit Agreement requires the Company to comply with certain financial covenants, including requiring that the Company maintain a (i) total leverage ratio (the “Leverage Ratio”), defined as the ratio of total funded debt to Adjusted EBITDA (as defined in the Credit Agreement), of at least 3.50 to 1.00 through December 31, 2020, and 3.25 to 1.00 thereafter and (ii) fixed charge coverage ratio (“FCCR Ratio”), defined as the ratio of Adjusted EBITDA less Unfinanced Capital Expenditures (as defined in the Credit Agreement) to Fixed Charges (as defined in the Credit Agreement), of not less than 1.20 to 1.00, in each case tested quarterly. The Credit Agreement also contains other customary restrictive covenants including (i) restrictions on the incurrence of additional indebtedness and additional liens on property, (ii) restrictions on permitted acquisitions and other investments and (iii) limitations on asset sales, mergers and acquisitions. Further, the Credit Agreement limits the Company’s payment of future dividends and distributions and share repurchases by the Company.

LEASES
LEASES	7. LEASES The Company leases certain office facilities under long-term, non-cancellable operating leases that expire at various dates through the year 2027. In addition, the Company is obligated under finance leases for certain furniture and office equipment that expire at various dates through the year 2022. From time to time, the Company enters into non-cancelable leases for some of our facility and equipment needs. These leases allow the Company to conserve cash by paying a monthly lease rental fee for the use of facilities and equipment rather than purchasing them. The Company’s leases have remaining terms ranging from one to eight years, some of which may include options to extend the leases for up to five years, and some of which may include options to terminate the leases within one year. Currently, all of the Company’s leases contain fixed payment terms. The Company may decide to cancel or terminate a lease before the end of its term, in which case we are typically liable to the lessor for the remaining lease payments under the term of the lease. Additionally, all of our month-to-month leases are cancelable by the Company or the lessor, at any time, and are not included in our right-of-use asset or lease liability. As of April 3, 2020, the Company had no leases with residual value guarantees. Typically, the Company has purchase options on the equipment underlying its long-term leases. The Company may exercise some of these purchase options when the need for equipment is on-going and the purchase option price is attractive. Nonperformance-related default covenants, cross-default provisions, subjective default provisions and material adverse change clauses contained in material lease agreements, if any, are also evaluated to determine whether those clauses affect lease classification in accordance with “ASC” Topic 842-10-25. Leases are accounted for as operating or financing leases, depending on the terms of the lease. Financing Leases The Company leases certain equipment under financing leases. The economic substance of the leases is a financing transaction for acquisition of equipment and leasehold improvements. Accordingly, the right-of-use assets for these leases are included in the balance sheets in equipment and leasehold improvements, net of accumulated depreciation, with a corresponding amount recorded in current portion of financing lease obligations or noncurrent portion of financing lease obligations, as appropriate. The financing lease assets are amortized over the life of the lease or, if shorter, the life of the leased asset, on a straight-line basis and included in depreciation expense. The interest associated with financing lease obligations is included in interest expense. Right-of-use assets Operating leases are included in right-of-use assets, and current portion of lease liability and noncurrent portion of lease liability, as appropriate. Right-of-use assets and lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. As most of the Company’s leases do not provide an implicit rate to calculate present value, the Company determines this rate by estimating the Company’s incremental borrowing rate at the lease commencement date. The right-of-use asset also includes any lease payments made and initial direct costs incurred at lease commencement and excludes lease incentives. Our lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term.

Employees may elect to contribute up to 50% of their compensation limited to the amount allowed by tax laws. Company contributions are made solely at the discretion of the Company’s board of directors. The Company also had a defined contribution plan (the “Plan”) covering employees who have completed three months of service and who have attained 21 years of age. The Company elected to make matching contributions equal to 50% of the participants’ contributions to the Plan up to 6% of the individual participant’s compensation. Under the defined contribution plan, the Company may make discretionary matching contributions to employee accounts. The Company made matching contributions of approximately $0.9 million and $0.7 million during the three months ended April 3, 2020 and March 29, 2019, respectively. Variable Interest Entities On March 4, 2016, the Company and the Company’s wholly-owned subsidiary, WES acquired substantially all of the assets of Genesys and assumed certain specified liabilities of Genesys (collectively, the “Purchase”) pursuant to an Asset Purchase and Merger Agreement, dated as of February 26, 2016 (the “Agreement”), by and among Willdan Group, Inc., WES, WESGEN (as defined below), Genesys and Ronald W. Mineo (“Mineo”) and Robert J. Braun (“Braun” and, together with Mineo, the “Genesys Shareholders”). On March 5, 2016, pursuant to the terms of the Agreement, WESGEN, Inc., a non-affiliated corporation (“WESGEN”), merged (the “Merger” and, together with the Purchase, the “Acquisition”) with Genesys, with Genesys remaining as the surviving corporation. Genesys was acquired to strengthen the Company’s power engineering capability in the northeastern U.S., and also to increase client exposure and experience with universities. Genesys continues to be a professional corporation organized under the laws of the State of New York, wholly-owned by one or more licensed engineers. Pursuant to New York law, the Company does not own capital stock of Genesys. The Company has entered into an agreement with the Shareholder of Genesys pursuant to which the Shareholder will be prohibited from selling, transferring or encumbering the Shareholder’s ownership interest in Genesys without the Company’s consent. Notwithstanding the Company’s rights regarding the transfer of Genesys’s stock, the Company does not have control over the professional decision making of Genesys’s engineering services. The Company has entered into an administrative services agreement with Genesys pursuant to which WES will provide Genesys with ongoing administrative, operational and other non-professional support services. Genesys pays WES a service fee, which consists of all of the costs incurred by WES to provide the administrative services to Genesys plus ten percent of such costs, as well as any other costs that relate to professional service supplies and personnel costs. As a result of the administrative services agreement, the Company absorbs the expected losses of Genesys through its deferral of Genesys’s service fees owed to WES. The Company manages Genesys and has the power to direct the activities that most significantly impact Genesys’s performance, in addition to being obligated to absorb expected losses from Genesys. Accordingly, the Company is the primary beneficiary of Genesys and consolidates Genesys as a VIE. In addition, the Company concluded there is no noncontrolling interest related to the consolidation of Genesys because the Company determined that (i) the shareholder of Genesys does not have more than a nominal amount of equity investment at risk, (ii) WES absorbs the expected losses of Genesys through its deferral of Genesys’s service fees owed to WES and the Company has, since entering into the administrative services agreement, had to continuously defer service fees for Genesys, and (iii) the Company believes Genesys will continue to have a shortfall on payment of its service fees for the foreseeable future, leaving no expected residual returns for the shareholder. As of April 3, 2020, the Company had one VIE — Genesys.

Deferred tax assets and liabilities are recognized for the future tax consequences of temporary differences between the financial reporting basis and tax basis of the Company’s assets and liabilities, subject to a judgmental assessment of the recoverability of deferred tax assets. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is recorded when it is more likely than not that some of the deferred tax assets may not be realized. Significant judgment is applied when assessing the need for valuation allowances and appropriate consideration is given to all positive and negative evidence related to that realization. This assessment considers, among other matters, the nature, frequency and severity of recent losses, forecast of future profitability, the duration of statutory carry-forward periods, experience with tax attributes expiring unused, and tax planning alternatives. The weight given to these considerations depends upon the degree to which they can be objectively verified. Should a change in circumstances lead to a change in judgment about the utilization of deferred tax assets in future years, the Company would adjust the related valuation allowances in the period that the change in circumstances occurs, along with a corresponding increase or charge to income. During each fiscal year, management assesses the available positive and negative evidence to estimate if sufficient future taxable income will be generated to utilize existing deferred tax assets. Beginning in fiscal year 2017, the Company determined that it was more-likely-than-not that the entire California net operating loss will not be utilized prior to expiration. Significant pieces of objective evidence evaluated included our history of utilization of California net operating losses in prior years for each of our subsidiaries, as well as our forecasted amount of net operating loss utilization for certain members of the combined group. As a result, the Company recorded a valuation allowance in the amount of $86,000 at the end of fiscal year 2018 related to California net operating losses. There was no change to the valuation allowance during the three months ended April 3, 2020 or the three months ended March 29, 2019 . For acquired business entities, if the Company identifies changes to acquired deferred tax asset valuation allowances or liabilities related to uncertain tax positions during the measurement period and they relate to new information obtained about facts and circumstances that existed as of the acquisition date, those changes are considered a measurement period adjustment, and the Company records the offset to goodwill. The Company records all other changes to deferred tax asset valuation allowances and liabilities related to uncertain tax positions in current period income tax expense. The Company recognizes the tax benefit from uncertain tax positions if it is more likely than not that the tax positions will be sustained on examination by the tax authorities, based on the technical merits of the position. The tax benefit is measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. The Company recognizes interest and penalties related to unrecognized tax benefits in income tax expense. As of April 3, 2020, the Company recorded a liability of $0.1 million for uncertain tax positions related to miscellaneous tax deductions taken in open tax years. Included in this amount are $0.1 million of tax benefits that, if recognized, would affect the effective tax rate. Interest and penalties of $0.03 million have been recorded related to unrecognized tax benefits as of April 3, 2020. Based on management’s estimates and determination of an effective tax rate for the year, the Company recorded an income tax benefit of $1.6 million for the three months ended April 3, 2020, as compared to an income tax benefit of $0.9 million for the three months ended March 29, 2019. During the three months ended April 3, 2020, the difference between the effective tax rate and the federal statutory rate is primarily attributable to state taxes, the recognition of tax deductions related to the vesting of performance-based restricted stock units, nondeductible executive compensation, research and development tax credits, and the commercial building energy efficiency deduction. For the three months ended March 29, 2019, the difference between the effective tax rate and the federal statutory rate was primarily attributable to state taxes, the recognition of tax deductions related to the vesting of performance-based restricted stock units, nondeductible executive compensation and research and development tax credits. During the three months ended April 3, 2020, the Internal Revenue Service continued its audit of our tax return for the fiscal year ended December 30, 2016. The Company is not able to determine the impact of this examination due to the audit process having not been completed. On March 27, 2020, President Trump signed into law the Coronavirus Aid, Relief, and Economic Security (CARES ) Act (H.R. 748) which includes a number of provisions relating to refundable payroll tax credits, deferment of employer side social security payments, net operating loss carryback periods, alternative minimum tax credit refunds, modifications to the net interest deduction limitations and technical corrections to tax depreciation methods for qualified improvement property. Under ASC 740, the effects of new legislation are recognized upon enactment. Accordingly, the effects of the CARES Act have been incorporated into the income tax provision computation for the quarter ended April 3, 2020. These provisions did not have a material impact on the income tax provision. The Company anticipates deferring the employer side social security payments for payroll paid for the remainder of 2020.

EARNINGS PER SHARE (EPS)
EARNINGS PER SHARE (EPS)	11. EARNINGS PER SHARE (“EPS”) Basic EPS is computed by dividing net income available to common stockholders by the weighted‑average number of common shares outstanding. Diluted EPS is computed by dividing net income by the weighted‑average number of common shares outstanding and dilutive potential common shares for the period. Potential common shares include the weighted‑average dilutive effects of outstanding stock options and restricted stock awards using the treasury stock method. The following table sets forth the number of weighted‑average common shares outstanding used to compute basic and diluted EPS: Three months ended April 3, March 29, 2020 2019 (in thousands, except per share amounts) Net loss $ (8,154) $ (417) Weighted-average common shares outstanding 11,510 10,974 Effect of dilutive stock options and restricted stock awards — — Weighted-average common shares outstanding-diluted 11,510 10,974 Loss per share: Basic $ (0.71) $ (0.04) Diluted $ (0.71) $ (0.04) For the three months ended April 3, 2020 and March 29, 2019, the Company reported a net loss, and accordingly, all outstanding equity awards have been excluded from such periods because including them would have been anti-dilutive.

BUSINESS COMBINATIONS	12. BUSINESS COMBINATIONS Acquisition of E3, Inc. On October 28, 2019 The Company agreed to pay up to $44.0 million for the purchase of all of the capital stock of E3, Inc., which purchase price consists of (i) $27.0 million in cash paid The amount of the Earn-Out Payments to be paid will be determined based on The Purchase Agreement also contains customary representations and warranties regarding The Company borrowed $30.0 million under its Delayed Draw Term Loan on October 28, 2019 to fund the $27.0 million cash payment paid on the E3, Inc. Closing Date. The acquisition was accounted for as a business combination in accordance with ASC 805. Under ASC 805, the Company recorded the acquired assets and assumed liabilities at their estimated fair value with the excess allocated to goodwill. Goodwill represents the value the Company expects to achieve through the operational synergies, the expansion into new markets and the acquired company’s assembled work force. The Company estimates that the entire $21.5 million of goodwill resulting from the acquisition will be tax deductible. Preliminary consideration for the acquisition includes the following: E3, Inc. (in thousands) Cash paid $ 25,217 Other working capital adjustment 1,973 Issuance of common stock 5,000 Contingent Consideration 7,000 Total consideration $ 39,190 The following table summarizes the preliminary amounts for the acquired assets recorded at their estimated fair value as of the acquisition date: E3, Inc. (in thousands) Current assets $ 5,316 Non-current assets (1) 341 Cash 2,264 Equipment and leasehold improvements, net 409 Right-of-use assets 7,641 Current lease liability (750) Non-current lease liability (6,890) Liabilities (4,325) Backlog 2,500 Customer relationships 8,300 Tradename 2,000 Non-compete 900 Goodwill 21,484 Net assets acquired $ 39,190 (1) Excluded from non-current assets are equipment and leasehold improvements, net, right-of-use assets, customer relationships, tradename, backlog and goodwill. During the three months ended April 3, 2020, the Company made adjustments, primarily related to other working capital, to the consideration paid for E3 which resulted in an adjustment to the preliminary purchase price allocation of E3. The adjustments resulted in an aggregate increase of $1.9 million in the net carrying value of right-of-use assets and non-current lease liability and an aggregate decrease of $1.9 million in the net carrying value of current lease liability, liabilities and goodwill. The decrease in the fair value of intangible assets resulted in no change in the amortization expense for the fiscal three months ended April 3, 2020. There were no acquisition related costs associated with E3, Inc. included in other general and administrative expenses in the consolidated statements of comprehensive income for the three months ended April 3, 2020. During the three months ended April 3, 2020, the acquisition of E3, Inc. contributed $5.0 million in revenue and $0.9 million of income from operations. Acquisition of Onsite Energy Corporation On July 2, 2019, the Company acquired substantially all of the assets and liabilities of Onsite Energy Corporation (“Onsite Energy”), an energy efficiency services and project implementation firm that specializes in energy upgrades and commissioning for industrial facilities. The Company believes the acquisition will expand its presence in the California-based industrial energy management services. Pursuant to the terms of the Asset Purchase Agreement, dated July 2, 2019, by and between WES and Onsite Energy, WES will pay a maximum aggregate purchase price of $26.4 million, subject to certain holdback and working capital adjustments, to be paid in cash. Onsite Energy’s financial information is included within the Energy segment. The Company expects to finalize the purchase price allocation with respect to this transaction during the second quarter of fiscal year 2020. The acquisition was accounted for as a business combination in accordance with ASC 805. Under ASC 805, the Company recorded the acquired assets and assumed liabilities at their estimated fair value with the excess allocated to goodwill. Goodwill represents the value the Company expects to achieve through the operational synergies, the expansion into new markets and the acquired company’s assembled work force. The Company estimates that the entire $9.0 million of goodwill resulting from the acquisition will be tax deductible. Preliminary consideration for the acquisition includes the following: Onsite Energy (in thousands) Cash paid $ 24,411 Other working capital adjustment 494 Total consideration $ 24,905 The following table summarizes the preliminary amounts for the acquired assets recorded at their estimated fair value as of the acquisition date: Onsite Energy (in thousands) Current assets $ 19,387 Non-current assets (1) 10 Equipment and leasehold improvements, net 39 Right-of-use assets 828 Current lease liability (168) Non-current lease liability (660) Liabilities (12,222) Backlog 800 Customer relationships 7,374 Tradename 500 Goodwill 9,017 Net assets acquired $ 24,905 (1) Excluded from non-current assets are equipment and leasehold improvements, net, right-of-use assets, customer relationships, tradename, backlog and goodwill. During the three months ended April 3, 2020, the Company made adjustments, primarily related to other working capital, to the consideration paid for Onsite Energy which resulted in an adjustment to the preliminary purchase price allocation of Onsite Energy. The adjustments resulted in an aggregate increase of $2.9 million in the net carrying value of goodwill and an aggregate decrease of $2.9 million in the net carrying value of current assets. The increase in the fair value of intangible assets resulted in no change of the amortization expense for the fiscal three months ended April 3, 2020. There were $0.1 million in acquisition related costs associated with Onsite Energy included in other general and administrative expenses in the consolidated statements of comprehensive income for the three months ended April 3, 2020. During the three months ended April 3, 2020, the acquisition of Onsite Energy contributed $2.2 million in revenue and no income from operations. Acquisition of The Weidt Group On March 8, 2019, the Company acquired substantially all of the assets of the energy practice division of The Weidt Group Inc. (“The Weidt Group”). The Company believes the acquisition will expand its presence in the upper Midwest and better position the Company to help utilities make their grids more resilient. Pursuant to the terms of the Asset Purchase Agreement, dated March 8, 2019, by and among the Company, WES and The Weidt Group, WES paid a cash purchase price of $22.1 million, inclusive of working capital adjustments. The Weidt Group’s financial information is included within the Energy segment. The Company finalized the purchase price allocation with respect to this transaction in the first quarter of 2020. The acquisition was accounted for as a business combination in accordance with ASC 805. Under ASC 805, the Company recorded the acquired assets and assumed liabilities at their estimated fair value with the excess allocated to goodwill. Goodwill represents the value the Company expects to achieve through the operational synergies, the expansion into new markets and the acquired company’s assembled work force. The Company estimates that the entire $11.5 million of goodwill resulting from the acquisition will be tax deductible. Consideration for the acquisition includes the following: The Weidt Group (in thousands) Cash paid $ 22,136 Other working capital adjustment - Total consideration $ 22,136 The following table summarizes the amounts for the acquired assets recorded at their estimated fair value as of the acquisition date: The Weidt Group (in thousands) Current assets $ 2,317 Non-current assets (1) 25 Equipment and leasehold improvements, net 198 Right-of-use assets 1,730 Current lease liability (245) Non-current lease liability (1,533) Liabilities (612) Backlog 750 Customer relationships 4,240 Tradename 550 Developed technology 3,170 Goodwill 11,546 Net assets acquired $ 22,136 (1) Excluded from non-current assets are equipment and leasehold improvements, net, right-of-use assets, customer relationships, tradename, developed technology, backlog and goodwill. There were $0.05 million in acquisition related costs associated with The Weidt Group included in other general and administrative expenses in the condensed consolidated statements of comprehensive income for the three months ended April 3, 2020. During the three months ended April 3, 2020, the acquisition of The Weidt Group contributed $3.7 million in revenue and $0.3 million of income from operations. The following unaudited pro forma financial information for the three months ended April 3, 2020 and March 29, 2019 assumes that the acquisitions of substantially all of the assets and liabilities of E3, Inc., Onsite Energy and The Weidt Group occurred on the first day of the year prior to the year of acquisition: Three Months Ended April 3, March 29, 2020 2019 (in thousands, except per share data) Pro forma revenue $ 106,026 $ 102,399 Pro forma income (loss) from operations $ (8,269) $ 1,853 Pro forma net income (loss) (1) $ (8,154) $ 231 Earnings (Loss) per share: Basic $ (0.71) $ 0.02 Diluted $ (0.71) $ 0.02 Weighted average shares outstanding: Basic 11,510 11,189 Diluted 11,510 11,189 (1) Adjustments to pro forma net income include income from operations, amortization and interest expenses. This pro forma supplemental information does not purport to be indicative of what the Company’s operating results would have been had the acquisition of all the capital stock of E3, Inc. and that the acquisitions of substantially all of the assets and liabilities of Onsite Energy and The Weidt Group each occurred on the first day of the year prior to the year of acquisition and may not be indicative of future operating results. During the three months ended April 3, 2020, the acquisition of E3, Inc., Onsite Energy and The Weidt Group contributed $10.9 million in revenue and $1.2 million of income from operations.

CONTINGENCIES

CONTINGENCIES
CONTINGENCIES	13. CONTINGENCIES Claims and Lawsuits The Company is subject to claims and lawsuits from time to time, including those alleging professional errors or omissions that arise in the ordinary course of business against firms that operate in the engineering and consulting professions. The Company carries professional liability insurance, subject to certain deductibles and policy limits, for such claims as they arise and may from time to time establish reserves for litigation that is considered probable of a loss. In accordance with accounting standards regarding loss contingencies, the Company accrues an undiscounted liability for those contingencies where the incurrence of a loss is probable and the amount can be reasonably estimated, and discloses the amount accrued and an estimate of any reasonably possible loss in excess of the amount accrued, if such disclosure is necessary for the Company’s financial statements not to be misleading. The Company does not accrue liabilities when the likelihood that the liability has been incurred is probable but the amount cannot be reasonably estimated, or when the liability is believed to be only reasonably possible or remote. Because litigation outcomes are inherently unpredictable, the Company’s evaluation of legal proceedings often involves a series of complex assessments by management about future events and can rely heavily on estimates and assumptions. If the assessments indicate that loss contingencies that could be material to any one of the Company’s financial statements are not probable, but are reasonably possible, or are probable, but cannot be estimated, then the Company will disclose the nature of the loss contingencies, together with an estimate of the possible loss or a statement that such loss is not reasonably estimable. While the consequences of certain unresolved proceedings are not presently determinable, and a reasonable estimate of the probable and reasonably possible loss or range of loss in excess of amounts accrued for such proceedings cannot be made, an adverse outcome from such proceedings could have a material adverse effect on the Company’s earnings in any given reporting period. However, in the opinion of the Company’s management, after consulting with legal counsel, and taking into account insurance coverage, the ultimate liability related to current outstanding claims and lawsuits is not expected to have a material adverse effect on the Company’s financial statements.

SUBSEQUENT EVENTS
SUBSEQUENT EVENTS	14. SUBSEQUENT EVENTS Borrowing under Revolving Credit Facility On April 7, 2020, the Company borrowed $10.0 million under the Revolving Credit Facility, which reduced the future borrowing capacity under the Revolving Credit Facility to $36.0 million. Third Amendment to the Credit Agreement On May 6, 2020, the Company entered into the Third Amendment to the Amended and Restated Credit Agreement (the “Third Amendment”) which, among other things, amends or suspends certain covenants contained in the Credit Agreement from March 5, 2020 until the earlier of (i) July 2, 2021 and (ii) the last day of the fiscal quarter in which the Company delivers an irrevocable election to terminate the covenant relief granted by the Third Amendment (the “Covenant Relief Period”). The Third Amendment increases the maximum Leverage Ratio the Company is permitted to maintain during the Covenant Relief Period and replaces the covenant to maintain a minimum FCCR Ratio during the Covenant Relief Period with a requirement to maintain a minimum Adjusted EBITDA (as defined in the Third Amendment). During the Covenant Relief Period, no further delayed draw term loans may be borrowed under the Credit Facilities and the Company is prohibited from engaging in share repurchases or making any Permitted Acquisitions (as defined in the Credit Agreement). Additionally, during the Covenant Relief Period, the aggregate amount of all capital expenditures made by the Company may not exceed $7.0 million, and the Company is prohibited from making any earn-out payments if, after giving effect to such earn-out payment, the Company’s liquidity would be less than $5.0 million or the aggregate amount of all earn-out payments made by the Company during the Covenant Relief Period would exceed $7.0 million. As part of the Third Amendment, borrowings under the Credit Agreement will bear interest (A) from March 5, 2020 until the date of the Third Amendment, at a rate equal to one-month LIBOR plus 2.0%, (B) from the date of the Third Amendment until the date the administrative agent receives the Company’s financial statements for the quarter ending July 3, 2020, at a rate equal to either, at the Company’s option, (i) the highest of the prime rate, the Federal Funds Rate plus 0.5% or one-month LIBOR plus 1.00% (the “Base Rate”) or (ii) one-month LIBOR, in each case plus an applicable margin of 1.50% with respect to Base Rate borrowings and 2.50% with respect to LIBOR borrowings and (C) at all other times during the Covenant Relief Period, at a rate equal to either, at the Company’s option, (i) the Base Rate or (ii) one-month LIBOR, in each case plus an applicable margin ranging from 0.125% to 1.50% with respect to Base Rate borrowings and 1.125% to 2.50% with respect to LIBOR borrowings, depending on the Leverage Ratio; provided, that one-month LIBOR shall not be less than 0.75% during the Covenant Relief Period. During the Covenant Relief Period, the Company will pay a commitment fee for the unused portion of the Revolving Credit Facility and the delayed draw term loan facility, which ranges from 0.15% to 0.45% per annum depending on the Leverage Ratio, and fees on the face amount of any letters of credit outstanding under the Revolving Credit Facility, which range from 0.84% to 2.50% per annum, in each case, depending on whether such letter of credit is a performance or financial letter of credit and the Leverage Ratio. After the Covenant Relief Period, borrowings under the Credit Agreement will bear interest at a rate equal to either, at the Company’s option, (i) the Base Rate or (ii) one-month LIBOR, in each case plus an applicable margin ranging from 0.125% to 1.00% with respect to Base Rate borrowings and 1.125% to 2.00% with respect to LIBOR borrowings, depending on the Leverage Ratio; provided, that one-month LIBOR shall not be less than 0.00%. After the Covenant Relief Period, the Company will pay a commitment fee for the unused portion of the Revolving Credit Facility and the delayed draft term loan facility, which will range from 0.15% to 0.35% per annum depending on the Leverage Ratio, and fees on the face amount of any letters of credit outstanding under the Revolving Credit Facility, which will range from 0.84% to 2.00% per annum, in each case, depending on whether such letter of credit is a performance or financial letter of credit and the Leverage Ratio.

ORGANIZATION AND OPERATIONS OF THE COMPANY
Basis of Presentation	The accounting policies followed by the Company are set forth in Part II, Item 8, Note 1, Organization and Operations of the Company , of the Notes to Consolidated Financial Statements included in the Company’s Annual Report on Form 10‑K for the fiscal year ended December 27, 2019. In the opinion of management, all adjustments necessary to fairly state the Condensed Consolidated Financial Statements have been made. All such adjustments are of a normal, recurring nature. Certain information and footnote disclosures normally included in the Consolidated Financial Statements prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”).
Fiscal Years	Fiscal Years The Company operates and reports its annual financial results based on 52 or 53-week periods ending on the Friday closest to December 31. The Company operates and reports its quarterly financial results based on the 13-week period ending on the Friday closest to March 31, June 30 and September 30 and the 13 or 14-week period ending on the Friday closest to December 31, as applicable. Fiscal years 2019, 2018 and 2017 contained 52 weeks. All references to years in the notes to consolidated financial statements represent fiscal years.
Use of Estimates	Use of Estimates The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements. Estimates also affect the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.
Recent Accounting Pronouncements	Accounting Pronouncements Recently Adopted In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”). ASU 2016-13 requires entities to report “expected” credit losses on financial instruments and other commitments to extend credit rather than the current “incurred loss” model. These expected credit losses for financial assets held at the reporting date are to be based on historical experience, current conditions, and reasonable and supportable forecasts. ASU 2016-13 will also require enhanced disclosures relating to significant estimates and judgments used in estimating credit losses, as well as the credit quality. The Company adopted this standard effective December 28, 2019. The adoption of this standard did not have a material impact on the Company’s Condensed Consolidated Financial Statements Accounting Pronouncements Recently Issued In December 2019, the FASB issued ASU No. 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes” (“ASU 2019-12”). ASU 2019-12 amends the accounting for income taxes by, among other things, removing: (i) The exception to the incremental approach for intraperiod tax allocation when there is a loss from continuing operations and income or a gain from other items (for example, discontinued operations or other comprehensive income); (ii) The exception to the requirement to recognize a deferred tax liability for equity method investments when a foreign subsidiary becomes an equity method investment; (iii) The exception to the ability not to recognize a deferred tax liability for a foreign subsidiary when a foreign equity method investment becomes a subsidiary; and (iv) The exception to the general methodology for calculating income taxes in an interim period when a year-to-date loss exceeds the anticipated loss for the year. The amendments are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020, which for the Company is the first quarter of fiscal 2021. The Company is currently evaluating the impact this update will have on its Condensed Consolidated Financial Statements.
Contract Accounting	3. REVENUES The Company enters into contracts with its clients that contain various types of pricing provisions, including fixed price, time-and-materials, and unit-based provisions. The Company recognizes revenues in accordance with ASU 2014-09, Revenue from Contracts with Customer, codified as ASC Topic 606 and the related amendments (collectively “ASC 606”). As such, the Company identifies a contract with a customer, identifies the performance obligations in the contract, determines the transaction price, allocates the transaction price to each performance obligation in the contract and recognizes revenues when (or as) the Company satisfies a performance obligation. The following table reflects the Company’s two reportable segments and the types of contracts that each most commonly enters into for revenue generating activities. Segment Contract Type Revenue Recognition Method Time-and-materials Time-and-materials Energy Unit-based Unit-based Software license Unit-based Fixed price Percentage-of-completion Time-and-materials Time-and-materials Engineering and Consulting Unit-based Unit-based Fixed price Percentage-of-completion Revenue on the vast majority of the Company’s contracts is recognized over time because of the continuous transfer of control to the customer. Revenue on fixed price contracts is recognized on the percentage-of-completion method based generally on the ratio of direct costs incurred-to-date to estimated total direct costs at completion. The Company uses the percentage-of-completion method to better match the level of work performed at a certain point in time in relation to the effort that will be required to complete a project. In addition, the percentage-of-completion method is a common method of revenue recognition in the Company’s industry. Many of the Company’s fixed price contracts involve a high degree of subcontracted fixed price effort and are relatively short in duration, thereby lowering the risks of not properly estimating the percent complete. Revenue on time-and-materials and unit-based contracts is recognized as the work is performed in accordance with the specific rates and terms of the contract. The Company recognizes revenues for time-and-materials contracts based upon the actual hours incurred during a reporting period at contractually agreed upon rates per hour and also includes in revenue all reimbursable costs incurred during a reporting period. Certain of the Company’s time-and-materials contracts are subject to maximum contract values and, accordingly, when revenue is expected to exceed the maximum contract value, these contracts are generally recognized under the percentage-of-completion method, consistent with fixed price contracts. For unit-based contracts, the Company recognizes the contract price of units of a basic production product as revenue when the production product is delivered during a period. Revenue recognition for software licenses issued by the Energy segment is generally recognized at a point in time, utilizing the unit-based revenue recognition method, upon acceptance of the software by the customer and in recognition of the fulfillment of the performance obligation. Certain additional performance obligations beyond the base software license may be separated from the gross license fee and recognized on a straight-line basis over time. Revenue for amounts that have been billed but not earned is deferred, and such deferred revenue is referred to as contract liabilities in the accompanying condensed consolidated balance sheets. To determine the proper revenue recognition method for contracts, the Company evaluates whether two or more contracts should be combined and accounted for as one single contract and whether the combined contract should be accounted for as one performance obligation. With respect to the Company’s contracts, it is rare that multiple contracts should be combined into a single performance obligation. This evaluation requires significant judgment and the decision to combine a group of contracts or separate a single contract into multiple performance obligations could change the amount of revenue and profit recorded in a given period. Contracts are considered to have a single performance obligation if the promise to transfer the individual goods or services is not separately identifiable from other promises in the contracts, which is mainly because the Company provides a significant service of integrating a complex set of tasks and components into a single project or capability. The Company may enter into contracts that include separate phases or elements. If each phase or element is negotiated separately based on the technical resources required and/or the supply and demand for the services being provided, the Company evaluates if the contracts should be segmented. If certain criteria are met, the contracts would be segmented which could result in revenues being assigned to the different elements or phases with different rates of profitability based on the relative value of each element or phase to the estimated total contract revenue. Segmented contracts may comprise up to approximately 2.0% to 3.0% of the Company’s consolidated contract revenue. Contracts that cover multiple phases or elements of the project or service lifecycle (development, construction and maintenance and support) may be considered to have multiple performance obligations even when they are part of a single contract. For contracts with multiple performance obligations, the Company allocates the transaction price to each performance obligation using the best estimate of the standalone selling price of each distinct good or service in the contract. For the periods presented, the value of the separate performance obligations under contracts with multiple performance obligations (generally measurement and verification tasks under certain energy performance contracts) were not material. In cases where the Company does not provide the distinct good or service on a standalone basis, the primary method used to estimate standalone selling price is the expected cost plus a margin approach, under which the Company forecasts the Company’s expected costs of satisfying a performance obligation and then adds an appropriate margin for the distinct good or service. The Company provides quality of workmanship warranties to customers that are included in the sale and are not priced or sold separately or do not provide customers with a service in addition to assurance of compliance with agreed-upon specifications and industry standards. The Company does not consider these types of warranties to be separate performance obligations. In some cases, the Company has a master service or blanket agreement with a customer under which each task order releases the Company to perform specific portions of the overall scope in the service contract. Each task order is typically accounted for as a separate contract because the task order establishes the enforceable rights and obligations, and payment terms. Under ASC 606, variable consideration should be considered when determining the transaction price and estimates should be made for the variable consideration component of the transaction price, as well as assessing whether an estimate of variable consideration is constrained. For certain of the Company’s contracts, variable consideration can arise from modifications to the scope of services resulting from unapproved change orders or customer claims. Variable consideration is included in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. The Company estimates of variable consideration and determination of whether to include estimated amounts in the transaction price are based largely on assessments of legal enforceability, the Company’s performance, and all information (historical, current and forecasted) that is reasonably available to the Company. Due to the nature of the work required to be performed on many of the Company’s performance obligations, the estimation of total revenue and cost at completion is complex, subject to many variables and requires significant judgment. As a significant change in one or more of these estimates could affect the profitability of the Company’s contracts, the Company reviews and updates the Company’s contract-related estimates regularly through a company-wide disciplined project review process in which management reviews the progress and execution of the Company’s performance obligations and the estimate at completion (EAC). As part of this process, management reviews information including, but not limited to, any outstanding key contract matters, progress towards completion and the related program schedule and the related changes in estimates of revenues and costs. Management must make assumptions and estimates regarding labor productivity and availability, the complexity of the work to be performed, the cost and availability of materials, the performance of subcontractors, and the availability and timing of funding from the customer, among other variables. The Company recognizes adjustments in estimated profit on contracts under the cumulative catch-up method. Under this method, the impact of the adjustment on profit recorded to date is recognized in the period the adjustment is identified. Revenue and profit in future periods of contract performance is recognized using the adjusted estimate. If at any time the estimate of contract profitability indicates an anticipated loss on the contract, the Company recognizes the full amount of estimated loss in the period it is identified. Contracts are often modified to account for changes in contract specifications and requirements. The Company considers contract modifications to exist when the modification either creates new rights or obligations or changes the existing enforceable rights or obligations. Most of the Company’s contract modifications are for goods or services that are not distinct from existing contracts due to the significant integration provided in the context of the contract and are accounted for as if they were part of the original contract. The effect of a contract modification that is not distinct from the existing contract on the transaction price and the Company’s measure of progress for the performance obligation to which it relates is recognized as an adjustment to revenue (either as an increase in or a reduction of revenue) on a cumulative catch-up basis. For contract modifications that result in the promise to deliver goods or services that are distinct from the existing contract and the increase in price of the contract is for the same amount as the standalone selling price of the additional goods or services included in the modification, the Company accounts for such contract modifications as a separate contract. The Company includes claims to vendors, subcontractors and others as a receivable and a reduction in recognized costs when enforceability of the claim is established by the contract and the amounts are reasonably estimable and probable of being recovered. The amounts are recorded up to the extent of the lesser of the amounts management expects to recover or to costs incurred. Billing practices are governed by the contract terms of each project based upon costs incurred, achievement of milestones or pre-agreed schedules. Billings do not necessarily correlate with revenue recognized using the percentage-of-completion method of revenue recognition. Direct costs of contract revenue consist primarily of that portion of technical and nontechnical salaries and wages that has been incurred in connection with revenue producing projects. Direct costs of contract revenue also include production expenses, subcontractor services and other expenses that are incurred in connection with revenue producing projects. Direct costs of contract revenue exclude that portion of technical and nontechnical salaries and wages related to marketing efforts, vacations, holidays and other time not spent directly generating revenue under existing contracts. Such costs are included in general and administrative expenses. Additionally, payroll taxes, bonuses and employee benefit costs for all Company personnel are included in general and administrative expenses in the accompanying consolidated statements of comprehensive income since no allocation of these costs is made to direct costs of contract revenue. No allocation of facilities costs is made to direct costs of contract revenue. Other companies may classify as direct costs of contract revenue some of the costs that the Company classifies as general and administrative costs. The Company expenses direct costs of contract revenue when incurred. Included in revenue and costs are all reimbursable costs for which the Company has the risk or on which the fee was based at the time of bid or negotiation. No revenue or cost is recorded for costs in which the Company acts solely in the capacity of an agent and has no risks associated with such costs. Accounts receivable are carried at original invoice amount less an estimate made for doubtful accounts based upon a review of all outstanding amounts on a quarterly basis. Management determines allowances for doubtful accounts through specific identification of amounts considered to be uncollectible and potential write-offs, plus a non-specific allowance for other amounts for which some potential loss has been determined to be probable based on current and past experience. The Company’s historical credit losses have been minimal with governmental entities and large public utilities, but disputes may arise related to these receivable amounts. Accounts receivable are written off when deemed uncollectible. Recoveries of accounts receivable previously written off are recorded when received. Retainage, included in contract assets, represents amounts withheld from billings to the Company’s clients pursuant to provisions in the contracts and may not be paid to the Company until specific tasks are completed or the project is completed and, in some instances, for even longer periods. At April 3, 2020 and December 27, 2019, contract assets included retainage of approximately $4.4 million and $5.4 million, respectively. In addition to the above, the Company derives revenue from software licenses and professional services and maintenance fees. In accordance with ASC 606, the Company performs an assessment of each contract to identify the performance obligations, determine the overall transaction price for the contract, allocate the transaction price to the performance obligations, and recognize the revenue when the performance obligations are satisfied. The Company utilizes the residual approach by which it estimates the standalone selling price by reference to the total transaction price less the sum of the observable standalone selling prices of other goods or services promised in the contract.
