BASIS OF PRESENTATION, ORGANIZATION AND OPERATIONS OF THE COMPANY
BASIS OF PRESENTATION, ORGANIZATION AND OPERATIONS OF THE COMPANY	1.BASIS OF PRESENTATION, ORGANIZATION AND OPERATIONS OF THE COMPANY Basis of Presentation The accompanying unaudited interim condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) and pursuant to the rules and regulations of the Securities and Exchange Commission and reflect all adjustments, which consist of only normal recurring adjustments, which are, in the opinion of management, necessary for a fair presentation of the consolidated results for the interim periods presented. 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, with consideration of business days. Results for the interim periods are not necessarily indicative of results for the full year. Certain information and footnote disclosures normally included in annual consolidated financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. The consolidated financial statements should be read in conjunction with Willdan Group, Inc.’s 2014 Annual Report on Form 10-K filed on March 31, 2015. Nature of Business Willdan Group, Inc. and subsidiaries (“Willdan Group” or the “Company”) is a provider of professional technical and consulting services, including comprehensive energy efficiency solutions, for utilities, private industry, and public agencies at all levels of government, primarily in California and New York. The Company also has operations in Arizona, Florida, Kansas, Oregon, Texas, Washington and Washington, D.C. The Company provides a broad range of complementary services including energy efficiency, engineering and planning, economic and financial consulting, and national preparedness and interoperability. The Company’s clients primarily consist of public and governmental agencies, including cities, counties, public utilities, redevelopment agencies, water districts, school districts and universities, state agencies, federal agencies, a variety of other special districts and agencies, private utilities and industry and tribal governments. The Company enables their clients to provide a wide range of specialized services without the clients having to incur and maintain the overhead necessary to develop staffing in-house. Principles of Consolidation The consolidated financial statements include the accounts of Willdan Group, Inc. and its wholly owned subsidiaries, Willdan Engineering, Willdan Energy Solutions, Public Agency Resources, Willdan Financial Services and Willdan Homeland Solutions and their respective subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. Accounting for Contracts The Company enters into contracts with its clients that contain three principal types of pricing provisions: fixed price, time-and-materials, and unit-based. Revenue on fixed price contracts is recognized on the percentage-of-completion method based generally on the ratio of direct costs (primarily exclusive of depreciation and amortization costs) incurred to date to estimated total direct costs at completion. Revenue on time-and-materials and unit-based contracts is recognized as the work is performed in accordance with the specific terms of the contract. Contracts that provide for multiple services or deliverables are evaluated as multiple element arrangements to determine the appropriate unit of accounting, allocation of contract value, and method of revenue recognition for each element. Revenue for amounts that have been billed but not earned is deferred and such deferred revenue is referred to as billings in excess of costs and estimated earnings on uncompleted contracts in the accompanying consolidated balance sheets. Service-related contracts, including operations and maintenance services and a variety of technical assistance services, are accounted for over the period of performance, in proportion to the costs of performance. Award and incentive fees are recorded when they are fixed or determinable and consider customer contract terms. Adjustments to contract cost estimates are made in the periods in which the facts requiring such revisions become known. When the revised estimate indicates a loss, such loss is provided for currently in its entirety. Claims revenue is recognized only upon resolution of the claim. Change orders in dispute are evaluated as claims. Costs related to un-priced change orders are expensed when incurred and recognition of the related contract revenue is based on an evaluation of the probability of recovery of the costs. Estimated profit is recognized for un-priced change orders if realization of the expected price of the change order is probable. Applying the percentage-of-completion method of recognizing revenue requires the Company to estimate the outcome of its long-term contracts. The Company forecasts such outcomes to the best of its knowledge and belief of current and expected conditions and its expected course of action. Differences between the Company’s estimates and actual results often occur resulting in changes to reported revenue and earnings. Such changes could have a material effect on future consolidated financial statements. 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 operations 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 the allowance for doubtful accounts by identifying troubled accounts and by using historical experience applied to an aging of accounts. Credit risk is generally minimal with governmental entities, but disputes may arise related to these receivable amounts. Accounts receivables are written off when deemed uncollectible. Recoveries of accounts receivables previously written off are recorded when received. Retainage is included in accounts receivable in the accompanying consolidated financial statements. Retainage represents the billed amount that is retained by the customer, in accordance with the terms of the contract, generally until performance is substantially complete. At July 3, 2015 and January 2, 2015, the Company had retained accounts receivable of approximately $943,000 and $700,000, respectively. Goodwill Goodwill represents the excess of costs over fair value of the assets acquired. The goodwill, which has an indefinite useful life, is not amortized, but instead tested for impairment at least annually or more frequently if events and circumstances indicate that the asset might be impaired. An impairment loss is recognized to the extent that the carrying amount exceeds the reporting unit’s fair value. The Company tests goodwill at least annually for possible impairment. The Company completes annual testing of goodwill as of the last day of the first month of its fourth fiscal quarter each year to determine whether there is impairment. In addition to the annual test, the Company regularly evaluates whether events and circumstances have occurred that may indicate a potential impairment of goodwill. As of July 3, 2015, the Company had $16.9 million of goodwill, which primarily relates to its Energy Efficiency Services reporting segment and the acquisitions of Abacus and 360 Energy and also relates to its Public Finance Services reporting segment and the acquisition of Economists.com, LLC. The Company tests goodwill for impairment at the level of its reporting units, which are components of its operating segments. The process of testing goodwill for impairment involves an optional qualitative assessment on goodwill impairment of its reporting units to determine whether a quantitative assessment is necessary. If a quantitative assessment is warranted, the Company will then determine the fair value of the applicable reporting units. To estimate the fair value of its reporting units, the Company uses both an income approach based on management’s estimates of future cash flows and other market data and a market approach based upon multiples of EBITDA earned by similar public companies. Once the fair value is determined, the Company then compares the fair value of the reporting unit to its carrying value, including goodwill. If the fair value of the reporting unit is determined to be less than the carrying value, the Company performs an additional assessment to determine the extent of the impairment based on the implied fair value of goodwill compared with the carrying amount of the goodwill. In the event that the current implied fair value of the goodwill is less than the carrying value, an impairment charge is recognized. Inherent in such fair value determinations are significant judgments and estimates, including but not limited to assumptions about future revenue, profitability and cash flows, operational plans and interpretation of current economic indicators and market valuations. To the extent these assumptions are incorrect or economic conditions that would impact the future operations of the reporting units change, any goodwill may be deemed to be impaired, and an impairment charge could result in a material adverse effect on the financial position or results of operation. Fair Value of Financial Instruments The Company’s financial instruments consist primarily of cash, cash equivalents, accounts receivable, costs and estimated earnings in excess of billings on uncompleted contracts, other receivables, prepaid expenses and other current assets, excess of outstanding checks over bank balance, accounts payable, accrued liabilities and billings in excess of costs and estimated earnings on uncompleted contracts, and approximate their fair values because of the relatively short period of time between the origination of these instruments and their expected realization or payment. The carrying amounts of debt obligations approximate their fair values since the terms are comparable to terms currently offered by local lending institutions for loans of similar terms to companies with comparable credit risk. Use of Estimates The preparation of consolidated financial statements in conformity with generally accepted accounting principles in the U.S. 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. Liquidity The Company had $15.1 million of cash and cash equivalents as of July 3, 2015. The Company’s primary sources of liquidity are cash generated from operations and its revolving line of credit with BMO Harris Bank, National Association (“BMO”), which matures on March 24, 2016, subject to extension to March 24, 2017 (see Note 7). While the Company believes that its cash and cash equivalents on hand, cash generated by operating activities and funds available under its line of credit (if needed and if available) will be sufficient to finance its operating activities for at least the next 12 months, if the Company does experience a cash flow shortage or violate the current terms of its credit agreement, the Company may have difficulty obtaining additional funds on favorable terms, if at all, to meet its obligations as they come due in the normal course of business. Recent Accounting Pronouncements Discontinued Operations In April 2014, the FASB issued guidance on reporting discontinued operations. The new guidance changed the criteria for determining which disposals can be presented as discontinued operations and modifies related disclosure requirements. Under the new guidance, a discontinued operation is defined as a disposal of a component or group of components that is disposed of or is classified as held for sale and represents a strategic shift that has or will have a major effect on an entity’s operations and financial results. The guidance applies prospectively to new disposals and new classifications of disposal groups as held for sale after the effective date. The standard was required to be adopted in annual periods beginning on or after December 15, 2014. The adoption of this guidance did not have an impact on our consolidated financial position, results of operations or cash flows. Revenue Recognition In May 2014, the FASB issued an amendment to the accounting guidance related to revenue recognition. Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers: Topic 606, provides for a single comprehensive principles based standard for the recognition of revenue across all industries through the application of the following five-step process: Step 1—Identify the contract(s) with a customer, Step 2—Identify the performance obligations in the contract, Step 3—Determine the transaction price, Step 4—Allocate the transaction price to the performance obligations in the contract, and Step 5—Recognize revenue when (or as) the entity satisfies a performance obligation. The new guidance is effective for annual periods beginning after December 15, 2017. We are evaluating the impact that adopting this guidance will have on our consolidated financial statements, including the method of adoption.

BUSINESS COMBINATIONS

2.BUSINESS COMBINATIONS

On January 15, 2015, the Company and its wholly-owned subsidiary, Willdan Energy Solutions (“WES”) completed two separate acquisitions. The Company and WES acquired all of the outstanding shares of Abacus Resource Management Company (“Abacus”), an Oregon-based energy engineering company. In addition, the Company and WES also separately acquired substantially all of the assets of 360 Energy Engineers, LLC (“360 Energy”), a Kansas-based energy and engineering energy management consulting company.

Pursuant to the terms of the Stock Purchase Agreement, dated as of January 15, 2015, by and between the Company, WES, Abacus and the selling shareholders of Abacus (the “Abacus Shareholders”), WES will pay the Abacus Shareholders a maximum purchase price of $6.1 million, consisting of (i) $2.5 million in cash which was paid at closing, with the balance of $0.6 million paid after closing, (ii) 75,758 shares of Common Stock, par value $0.01 per share, of the Company (“Common Stock”) with a fair value of $0.9 million which were issued at closing, (iii) $1.25 million aggregate principal amount of promissory notes issued to the Abacus Shareholders at closing and (iv) up to $1.4 million in cash, based on the achievement of certain financial targets by Abacus at the end of the Company’s 2015 and 2016 fiscal years.

Pursuant to the terms of the Asset Purchase Agreement, dated January 15, 2015, by and between the Company, WES and 360 Energy, WES will pay 360 Energy a maximum purchase price of $15.0 million, consisting of (i) $4.9 million in cash which was paid at closing, (ii) 47,348 shares of Common Stock with a fair value of $0.6 million which were issued at closing, (iii) $3.0 million aggregate principal amount of promissory note issued to 360 Energy at closing and (iv) up to $6.5 million in cash, based on the achievement of certain financial targets by WES’s division made up of the assets acquired from, and the former employees of 360 Energy at the end of the Company’s 2015, 2016 and 2017 fiscal years. The Company provided a guaranty to 360 Energy which guarantees WES’s obligations under the promissory note issued to 360 Energy.

To finance the acquisitions of Abacus and 360 Energy, the Company borrowed $2.0 million under its delayed draw term loan facility. The Company used cash on hand to pay the remaining $5.4 million due at closing.

On April 3, 2015, the Company’s wholly-owned subsidiary, Willdan Financial Services (“WFS”) acquired substantially all of the assets of Economists.com, LLC (“Economists LLC”), a Texas-based economic analysis and financial solutions firm serving the municipal and public sectors. Pursuant to the terms of the Asset Purchase Agreement, dated April 3, 2015, by and between WFS and Economists LLC, WFS will pay Economists LLC a maximum purchase price of $1.1 million, consisting of (i) $0.5 million in cash which was paid at closing and (ii) up to $0.6 million in cash, based on the achievement of certain financial targets by the WFS division made up of the assets acquired from, and the former employees of Economists LLC at the end of the Company’s 2015, 2016 and 2017 fiscal years. The Company used cash on hand to pay the $0.5 million due at closing.

The acquisitions were accounted for as business combinations 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 and the expansion of the Company into new markets. The Company estimates that the entire $16.9 million of goodwill resulting from the acquisitions will be tax deductible. Consideration for the acquisitions includes the following:

	360 Energy		Abacus		Economists, LLC		Total

Cash paid	$	4,875,000	$	3,135,000	$	490,000	$	8,500,000

Issuance of notes payable	3,000,000		1,250,000		—		4,250,000
Contingent consideration	5,061,000		681,000		368,000		6,110,000

Total consideration	$	13,507,000	$	5,980,000	$	858,000	$	20,345,000

The following table summarizes the preliminary amounts for the acquired assets recorded at their estimated fair value as of the acquisition date:

	360 Energy		Abacus		Economists, LLC		Total

Cash acquired	$	—	$	332,000	$	—	$	332,000
Property, plant and equipment	153,000		104,000		—		257,000

Tradename	666,000		366,000		—		1,032,000
Non-compete agreements	876,000		137,000		—		1,013,000

Goodwill	11,613,000		4,385,000		858,000		16,856,000

Net assets acquired	$	13,507,000	$	5,980,000	$	858,000	$	20,345,000

As of July 3, 2015, the Company had not completed its final estimate of fair value of the assets acquired and liabilities assumed due to the timing of such transactions and incomplete information necessary to finalize such estimates of fair value. Accordingly, the Company has preliminarily estimated the fair values of the assets acquired and the liabilities assumed. The Company will finalize the fair value estimates within twelve months of the acquisition date.

The acquisition date fair value of the intangible asset relating to tradenames was estimated using comparable values ascribed in other recent market transactions as well as taking into account Abacus’s, 360 Energy’s and Economists LLC’s market position in their respective markets. These assets are deemed to have a finite life. As of July 3, 2015, the Company has contingent consideration payable of $6.1 million related to these acquisitions. Contingent consideration is subject to change for each reporting period through settlement. The Company measures the contingent earn-out liabilities at fair value on the date of acquisition and on a recurring basis using significant unobservable inputs classified within Level 3 of the fair value hierarchy. The Company uses a probability-weighted discounted income approach as a valuation technique to convert future estimated cash flows to a single present value amount. The significant unobservable inputs used in the fair value measurements are operating income projections over the earn-out period, and the probability outcome percentages assigned to each scenario. Significant increases or decreases to either of these inputs in isolation would result in a significantly higher or lower liability, with a higher liability capped by the contractual maximum of the contingent earn-out obligation. Ultimately, the liability will be equivalent to the amount paid, and the difference between the fair value estimate and amount paid will be recorded in earnings.

The following unaudited pro forma financial information for the three and six months ended July 3, 2015 and June 27, 2014 assumes the acquisitions occurred on December 28, 2013 as follows:

	Three Months Ended				Six Months Ended

This pro forma supplemental information does not purport to be indicative of what the company’s operating results would have been had these transactions occurred on December 28, 2013 and may not be indicative of future operating results.

During the six months ended July 3, 2015, these acquisitions contributed $11.4 million in revenue and $0.3 million of income from operations.

EARNINGS PER SHARE (EPS)

EARNINGS PER SHARE (EPS)

4.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 using the treasury stock method.

The following table sets forth the number of weighted-average shares used to compute basic and diluted EPS:

	Three Months Ended				Six Months Ended
	July 3, 2015		June 27, 2014		July 3, 2015		June 27, 2014

Net income	$	1,602,000	$	1,893,000	$	3,097,000	$	3,208,000


Weighted-average common shares outstanding	7,824,000		7,405,000		7,795,000		7,401,000
Effect of dilutive stock options	312,000		256,000		311,000		116,000

Weighted-average common shares outstanding-diluted	8,136,000		7,661,000		8,106,000		7,517,000


Earnings per share:
Basic	$	0.20	$	0.26	$	0.40	$	0.43

Diluted	$	0.20	$	0.25	$	0.38	$	0.43

For each of the three and six months ended July 3, 2015, 227,867 options were excluded from the calculation of dilutive potential common shares. For the three and six months ended June 27, 2014, 268,500 and 289,500 options, respectively, were excluded from the calculation of dilutive potential common shares. These options were not included in the computation of dilutive potential common shares because the assumed proceeds per share exceeded the average market price per share for the 2015 and 2014 periods. Accordingly, the inclusion of these options would have been anti-dilutive.

To finance the acquisitions of Abacus and 360 Energy, Willdan borrowed $2.0 million under its delayed draw term loan facility pursuant to the BMO Credit Agreement described below. The term loan bears interest at the LIBOR rate plus an applicable margin ranging between 2.25% and 2.75%, set at the LIBOR rate plus 2.75% as of July 3, 2015, and matures on March 24, 2016, subject to extension as described below. Interest on the term loan is payable quarterly, beginning April 13, 2015 and was 2.78% as of July 3, 2015. Principal on the term loan is payable on the last day of each March, June, September, and December in each year, commencing on March 31, 2015, with the amount of each such principal installment equal to: (i) $50,000 on the last day of March, June, September and December 2015, and (ii) all remaining outstanding principal amount on March 24, 2016. The term loan is governed by the terms of the BMO Credit Agreement.

On January 15, 2015, in connection with the completion of the acquisition of Abacus, WES issued promissory notes to Mark Kinzer (the “Kinzer Note”) and Steve Rubbert (the “Rubbert Note” and, together with the Kinzer Note, the “Abacus Notes”). The initial outstanding principal amounts of the Kinzer Note and the Rubbert Note were $625,000 and $625,000, respectively. The Abacus Notes provide for a fixed interest rate of 4% per annum. The Abacus Notes are fully amortizing and payable in equal monthly installments between January 15, 2015 and their January 15, 2017 maturity date. The Abacus Notes contain events of default provisions customary for documents of this nature. Mr. Kinzer and Mr. Rubbert have entered into a Subordination Agreement, dated as of January 15, 2015, in favor of BMO Harris, pursuant to which any indebtedness under the Abacus Notes is subordinated to any indebtedness under the BMO Credit Agreement. Through July 3, 2015 the Company had made payments of approximately $252,000 on the Abacus Notes and the outstanding balance was $998,000 as of July 3, 2015.

On January 15, 2015, in connection with the completion of the acquisition of 360 Energy, WES issued a promissory note to 360 Energy (the “360 Energy Note”). The initial outstanding principal amount of the 360 Energy Note was $3,000,000. The 360 Energy Note provides for a fixed interest rate of 4% per annum. The 360 Energy Note is fully amortizing and payable in equal monthly installments between January 15, 2015 and its January 15, 2018 maturity date. The 360 Energy Note contains events of default provisions customary for documents of this nature. 360 Energy has entered into a Subordination Agreement, dated as of January 15, 2015, in favor of BMO Harris, pursuant to which any indebtedness under the 360 Energy Note is subordinated to any indebtedness under the BMO Credit Agreement. Through July 3, 2015 the Company had made payments of approximately $481,000 on the 360 Energy Note and the outstanding balance was $2,518,000 as of July 3, 2015.

BMO Credit Facility: On March 24, 2014, the Company and its subsidiaries, as guarantors, entered into a credit agreement with BMO Harris Bank, N.A., or BMO, that provides for a revolving line of credit of up to $7.5 million, subject to a borrowing base calculation, and a delayed draw term loan facility of up to $2.5 million. The $7.5 million revolving credit facility includes a $5.0 million standby letter of credit sub-facility. On January 15, 2015, the Company and its subsidiaries, as guarantors, entered into the Second Amendment (the “Second Amendment”) to the Credit Agreement (as amended, the “BMO Credit Agreement”) to, among other things, permit the acquisitions of Abacus and 360 Energy, the incurrence of the notes and guarantees issued in connection with the acquisitions of Abacus and 360 Energy and to add Abacus as a guarantor under the BMO Credit Agreement. The Second Amendment also increased the amount available to the Company for borrowing under the delayed draw term loan facility from $2.5 million to $3.0 million. To finance the acquisition of Abacus and 360 Energy, the Company borrowed $2.0 million under the delayed draw term loan facility. As of July 3, 2015, there was approximately $1.9 million of term loans outstanding, with the remaining $1.1 million under the delayed draw term loan facility available for borrowing, and there was no outstanding borrowings under the revolving line of credit, with all $7.5 million under the revolving line of credit available for borrowing.

All borrowings under the revolving line of credit are limited to a borrowing base equal to roughly 75% of the eligible accounts receivable plus 50% of the lower of cost or market value of the Company’s eligible inventory, each term as defined in the BMO Credit Agreement. Under the BMO Credit Agreement, as of July 3, 2015, no cash amounts are restricted. The revolving line of credit matures on March 24, 2016 and term loans can be requested at any time prior to February 23, 2016. Subject to certain conditions, including that the Company is not in default under the BMO Credit Agreement and that the Company’s trailing twelve month EBITDA (as defined in the BMO Credit Agreement) is not less than $10.0 million as of the end of the third fiscal quarter of 2015, the Company may request that the maturity date be extended by one year to March 24, 2017 and term loans could accordingly be requested at any time prior to February 22, 2017. As of July 3, 2015, the Company was in compliance with the covenants and conditions that would allow an extension to March 24, 2017. If the conditions to extend are not met, the Company would either repay the outstanding balance or refinance the revolving line of credit.

Borrowings under the delayed draw term loan facility bear interest, at the Company’s option, at (a) the base rate plus an applicable margin ranging between 1.25% and 1.75%, or (b) the LIBOR rate plus an applicable margin ranging between 2.25% and 2.75%. Borrowings under the revolving line of credit bear interest, at the Company’s option, at (a) the base rate plus an applicable margin ranging between 0.75% and 1.25%, or (b) the LIBOR rate plus an applicable margin ranging between 1.75% and 2.25%. The applicable margin is determined based on the Company’s total leverage ratio.

Borrowings under the term loan facility and the revolving line of credit are guaranteed by all of the Company’s subsidiaries (the “Guarantors”) and secured by all of the Company’s and the Guarantors’ accounts receivable and other rights to payment, general intangibles, inventory and equipment. Pursuant to the BMO Credit Agreement, the Company also must pay a fee of up to 0.3% on unused commitments and customary fees on any letters of credit drawn under the facility.

The BMO Credit Agreement contains customary representations and affirmative covenants, including financial covenants that require the Company to maintain (i) a maximum total leverage ratio, measured as total funded debt (measured as the sum of all obligations for borrowed money, including subordinated debt, plus all capital lease obligations) plus capital leases plus financial letters of credit divided by a trailing twelve month EBITDA (as defined in the BMO Credit Agreement) measured on a rolling basis of not more than 2.25 for the first four fiscal quarters after the acquisitions of Abacus and 360 Energy, and not more than 2.0 thereafter; (ii) a minimum fixed charge coverage ratio (measured as the sum of EBITDA plus rent expense less unfinanced capital expenditures divided by the sum of rent expense plus principal payments plus cash taxes plus cash interest plus restricted payments plus distributions) of not less than 1.25; and (iii) a minimum tangible net worth of at least (x) the greater of (1) $5.0 million and (2) 85% of the Company’s actual tangible net worth as of March 31, 2015, plus (y) an amount equal to 50% of net income for the first fiscal quarter of 2015, and 50% of net income (only if positive) for each fiscal quarter ending thereafter, plus or minus (z) 80% of any adjustments to the Company’s tangible net worth arising as a result of the consummation of the acquisitions of Abacus and 360 Energy.

The BMO Credit Agreement also includes customary negative covenants, including (i) restrictions on the incurrence of additional indebtedness by the Company or the Guarantors other than indebtedness existing on the date of the BMO Credit Agreement, (ii) restrictions on the total consideration for all permitted acquisitions (including potential future earn-out obligations) shall not exceed $1.5 million during the term of the agreement and the total consideration for any individual permitted acquisition shall not exceed $750,000 without BMO’s consent, and (iii) limitations on asset sales, mergers and acquisitions. In addition, the credit agreement includes customary events of default. Upon the occurrence of an event of default, the interest rate may be increased by 2.0%, BMO has the option to make any loans then outstanding under the BMO Credit Agreement immediately due and payable, and BMO would no longer be obligated to extend further credit to the Company under the BMO Credit Agreement. As of July 3, 2015 the Company was in compliance with the covenants under the BMO Credit Agreement.

Insurance Premiums. The Company has also financed, from time to time, insurance premiums by entering into unsecured notes payable with insurance companies. During the Company’s annual insurance renewals in the fourth quarter of its fiscal year ended January 2, 2015, the Company elected to finance its insurance premiums for the upcoming fiscal year.

The Company has a discretionary bonus plan for regional managers, division managers and others as determined by the Company president. Bonuses are awarded if certain financial goals are achieved. The financial goals are not stated in the plan; rather they are judgmentally determined each year. In addition, the board of directors may declare discretionary bonuses to key employees and all employees are eligible for bonuses for outstanding performance. The Company’s compensation committee of the board of directors determines the compensation of the president and chief executive officer. Post Employment Health Benefits In May 2006, the Company’s board of directors approved providing lifetime health insurance coverage for Win Westfall, the Company’s former chief executive officer and current chairman of the board of directors, and his spouse and for Linda Heil, the widow of the Company’s former chief executive officer, Dan Heil. These benefits relate to past services provided to the Company. Accordingly, there is no unamortized compensation cost for the benefits.

INCOME TAXES	6 Months Ended
INCOME TAXES	Jul. 03, 2015
INCOME TAXES
INCOME TAXES	9.INCOME TAXES Income taxes are accounted for under the asset and liability method. 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. Areas of estimation include the Company’s consideration of future taxable income and ongoing prudent and feasible tax planning strategies. 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. As of July 3, 2015, the Company believes it is more likely than not that it will be able to realize all of its deferred tax assets. Accordingly, no valuation allowance is recorded as of the balance sheet date. The Company will continue to assess the need for a valuation allowance in the future. 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 July 3, 3015, the Company has not recorded a liability for uncertain tax positions. Based on management’s estimates and determination of an effective tax rate for the year, the Company recorded an income tax expense of $1.1 million and $2.2 million for the three and six months ended July 3, 2015, respectively, as compared to an income tax expense of $64,000 and $108,000 for the three and six months ended June 27, 2014, respectively. The difference between the tax expense recorded at July 3, 2015 and the expense that would be recorded by applying the federal statutory rate primarily relates to state income taxes and certain expenses that are non-deductible for tax purposes, including meals and entertainment, lobbying and compensation expense related to incentive stock options. Additionally, the income tax expense in the current quarter reflects an adjustment to the tax effected value of deferred tax assets and liabilities resulting from changes in the estimated effective state income tax rate.

SEGMENT INFORMATION

SEGMENT INFORMATION

10.SEGMENT INFORMATION

The Company has four reporting segments: Energy Efficiency Services, Engineering Services, Public Finance Services and Homeland Security Services. The Energy Efficiency Services segment, which consists of Willdan Energy Solutions, provides energy efficiency and sustainability consulting services to utilities, state agencies, municipalities, private industry and non-profit organizations. The Engineering Services segment consists of Willdan Engineering, Willdan Infrastructure and Public Agency Resources. The Engineering Services segment offers a broad range of engineering and planning services to our public and private sector clients. The Public Finance Services segment, which consists of Willdan Financial Services, provides expertise and support for the various financing techniques employed by public agencies to finance their operations and infrastructure along with the mandated reporting and other requirements associated with these financings. The Homeland Security Services segment, which consists of Willdan Homeland Solutions, provides national preparedness, homeland security consulting, public safety and emergency response services to cities, related municipal service agencies and other entities.

The accounting policies applied to determine the segment information are the same as those described in the summary of significant accounting policies included in the Company’s 2014 Annual Report on Form 10-K filed on March 31, 2015. There were no intersegment sales in the three and six month periods ended July 3, 2015 and June 27, 2014. Management evaluates the performance of each segment based upon income or loss from operations before income taxes. Certain segment asset information including expenditures for long-lived assets has not been presented as it is not reported to or reviewed by the chief operating decision maker. In addition, enterprise-wide service line contract revenue is not included as it is impracticable to report this information for each group of similar services.

Financial information with respect to the reportable segments as of and for the fiscal three and six months ended July 3, 2015 and as of and for the fiscal three and six months ended June 27, 2014 is as follows:

CONTINGENCIES	6 Months Ended
CONTINGENCIES	Jul. 03, 2015
CONTINGENCIES
CONTINGENCIES	11.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. City of Glendale v. Willdan Financial Services, Superior Court of California, Los Angeles County A complaint was filed against the Company on July 16, 2014 relating to a project performed by Willdan Financial Services to prepare a Cost of Services Analysis (a “COSA”) for the Department of Water and Power of the City of Glendale, California (the “City of Glendale”). The purpose of the COSA was to assist the City of Glendale in setting water rates for property owners. The lawsuit alleges that the City of Glendale suffered damages due to mistakes in the COSA, as follows: the City of Glendale received less revenue than anticipated in an amount exceeding $9,000,000; the City of Glendale was required to retain another consultant to prepare a new COSA at the cost of $130,000; and the City of Glendale incurred costs associated with noticing and conducting public hearings at a cost of $83,052. The Company denies the allegations asserted in the lawsuit and will vigorously defend against the claims. Additionally, this matter is covered by the Company’s professional liability insurance policy up to its policy limits.

BASIS OF PRESENTATION, ORGANIZATION AND OPERATIONS OF THE COMPANY (Policies)	6 Months Ended
	Jul. 03, 2015
BASIS OF PRESENTATION, ORGANIZATION AND OPERATIONS OF THE COMPANY
Basis of Presentation	Basis of Presentation The accompanying unaudited interim condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) and pursuant to the rules and regulations of the Securities and Exchange Commission and reflect all adjustments, which consist of only normal recurring adjustments, which are, in the opinion of management, necessary for a fair presentation of the consolidated results for the interim periods presented. 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, with consideration of business days. Results for the interim periods are not necessarily indicative of results for the full year. Certain information and footnote disclosures normally included in annual consolidated financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. The consolidated financial statements should be read in conjunction with Willdan Group, Inc.’s 2014 Annual Report on Form 10-K filed on March 31, 2015.
Principles of Consolidation	Principles of Consolidation The consolidated financial statements include the accounts of Willdan Group, Inc. and its wholly owned subsidiaries, Willdan Engineering, Willdan Energy Solutions, Public Agency Resources, Willdan Financial Services and Willdan Homeland Solutions and their respective subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation.
Accounting for Contracts	Accounting for Contracts The Company enters into contracts with its clients that contain three principal types of pricing provisions: fixed price, time-and-materials, and unit-based. Revenue on fixed price contracts is recognized on the percentage-of-completion method based generally on the ratio of direct costs (primarily exclusive of depreciation and amortization costs) incurred to date to estimated total direct costs at completion. Revenue on time-and-materials and unit-based contracts is recognized as the work is performed in accordance with the specific terms of the contract. Contracts that provide for multiple services or deliverables are evaluated as multiple element arrangements to determine the appropriate unit of accounting, allocation of contract value, and method of revenue recognition for each element. Revenue for amounts that have been billed but not earned is deferred and such deferred revenue is referred to as billings in excess of costs and estimated earnings on uncompleted contracts in the accompanying consolidated balance sheets. Service-related contracts, including operations and maintenance services and a variety of technical assistance services, are accounted for over the period of performance, in proportion to the costs of performance. Award and incentive fees are recorded when they are fixed or determinable and consider customer contract terms. Adjustments to contract cost estimates are made in the periods in which the facts requiring such revisions become known. When the revised estimate indicates a loss, such loss is provided for currently in its entirety. Claims revenue is recognized only upon resolution of the claim. Change orders in dispute are evaluated as claims. Costs related to un-priced change orders are expensed when incurred and recognition of the related contract revenue is based on an evaluation of the probability of recovery of the costs. Estimated profit is recognized for un-priced change orders if realization of the expected price of the change order is probable. Applying the percentage-of-completion method of recognizing revenue requires the Company to estimate the outcome of its long-term contracts. The Company forecasts such outcomes to the best of its knowledge and belief of current and expected conditions and its expected course of action. Differences between the Company’s estimates and actual results often occur resulting in changes to reported revenue and earnings. Such changes could have a material effect on future consolidated financial statements. 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 operations 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 the allowance for doubtful accounts by identifying troubled accounts and by using historical experience applied to an aging of accounts. Credit risk is generally minimal with governmental entities, but disputes may arise related to these receivable amounts. Accounts receivables are written off when deemed uncollectible. Recoveries of accounts receivables previously written off are recorded when received. Retainage is included in accounts receivable in the accompanying consolidated financial statements. Retainage represents the billed amount that is retained by the customer, in accordance with the terms of the contract, generally until performance is substantially complete. At July 3, 2015 and January 2, 2015, the Company had retained accounts receivable of approximately $943,000 and $700,000, respectively.
Goodwill	Goodwill Goodwill represents the excess of costs over fair value of the assets acquired. The goodwill, which has an indefinite useful life, is not amortized, but instead tested for impairment at least annually or more frequently if events and circumstances indicate that the asset might be impaired. An impairment loss is recognized to the extent that the carrying amount exceeds the reporting unit’s fair value. The Company tests goodwill at least annually for possible impairment. The Company completes annual testing of goodwill as of the last day of the first month of its fourth fiscal quarter each year to determine whether there is impairment. In addition to the annual test, the Company regularly evaluates whether events and circumstances have occurred that may indicate a potential impairment of goodwill. As of July 3, 2015, the Company had $16.9 million of goodwill, which primarily relates to its Energy Efficiency Services reporting segment and the acquisitions of Abacus and 360 Energy and also relates to its Public Finance Services reporting segment and the acquisition of Economists.com, LLC. The Company tests goodwill for impairment at the level of its reporting units, which are components of its operating segments. The process of testing goodwill for impairment involves an optional qualitative assessment on goodwill impairment of its reporting units to determine whether a quantitative assessment is necessary. If a quantitative assessment is warranted, the Company will then determine the fair value of the applicable reporting units. To estimate the fair value of its reporting units, the Company uses both an income approach based on management’s estimates of future cash flows and other market data and a market approach based upon multiples of EBITDA earned by similar public companies. Once the fair value is determined, the Company then compares the fair value of the reporting unit to its carrying value, including goodwill. If the fair value of the reporting unit is determined to be less than the carrying value, the Company performs an additional assessment to determine the extent of the impairment based on the implied fair value of goodwill compared with the carrying amount of the goodwill. In the event that the current implied fair value of the goodwill is less than the carrying value, an impairment charge is recognized. Inherent in such fair value determinations are significant judgments and estimates, including but not limited to assumptions about future revenue, profitability and cash flows, operational plans and interpretation of current economic indicators and market valuations. To the extent these assumptions are incorrect or economic conditions that would impact the future operations of the reporting units change, any goodwill may be deemed to be impaired, and an impairment charge could result in a material adverse effect on the financial position or results of operation.
Fair Value of Financial Instruments	Fair Value of Financial Instruments The Company’s financial instruments consist primarily of cash, cash equivalents, accounts receivable, costs and estimated earnings in excess of billings on uncompleted contracts, other receivables, prepaid expenses and other current assets, excess of outstanding checks over bank balance, accounts payable, accrued liabilities and billings in excess of costs and estimated earnings on uncompleted contracts, and approximate their fair values because of the relatively short period of time between the origination of these instruments and their expected realization or payment. The carrying amounts of debt obligations approximate their fair values since the terms are comparable to terms currently offered by local lending institutions for loans of similar terms to companies with comparable credit risk.
Use of Estimates	Use of Estimates The preparation of consolidated financial statements in conformity with generally accepted accounting principles in the U.S. 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.
Liquidity	Liquidity The Company had $15.1 million of cash and cash equivalents as of July 3, 2015. The Company’s primary sources of liquidity are cash generated from operations and its revolving line of credit with BMO Harris Bank, National Association (“BMO”), which matures on March 24, 2016, subject to extension to March 24, 2017 (see Note 7). While the Company believes that its cash and cash equivalents on hand, cash generated by operating activities and funds available under its line of credit (if needed and if available) will be sufficient to finance its operating activities for at least the next 12 months, if the Company does experience a cash flow shortage or violate the current terms of its credit agreement, the Company may have difficulty obtaining additional funds on favorable terms, if at all, to meet its obligations as they come due in the normal course of business.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Discontinued Operations In April 2014, the FASB issued guidance on reporting discontinued operations. The new guidance changed the criteria for determining which disposals can be presented as discontinued operations and modifies related disclosure requirements. Under the new guidance, a discontinued operation is defined as a disposal of a component or group of components that is disposed of or is classified as held for sale and represents a strategic shift that has or will have a major effect on an entity’s operations and financial results. The guidance applies prospectively to new disposals and new classifications of disposal groups as held for sale after the effective date. The standard was required to be adopted in annual periods beginning on or after December 15, 2014. The adoption of this guidance did not have an impact on our consolidated financial position, results of operations or cash flows. Revenue Recognition In May 2014, the FASB issued an amendment to the accounting guidance related to revenue recognition. Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers: Topic 606, provides for a single comprehensive principles based standard for the recognition of revenue across all industries through the application of the following five-step process: Step 1—Identify the contract(s) with a customer, Step 2—Identify the performance obligations in the contract, Step 3—Determine the transaction price, Step 4—Allocate the transaction price to the performance obligations in the contract, and Step 5—Recognize revenue when (or as) the entity satisfies a performance obligation. The new guidance is effective for annual periods beginning after December 15, 2017. We are evaluating the impact that adopting this guidance will have on our consolidated financial statements, including the method of adoption.

- Definition

Disclosure of accounting policy regarding (1) the principles it follows in consolidating or combining the separate financial statements, including the principles followed in determining the inclusion or exclusion of subsidiaries or other entities in the consolidated or combined financial statements and (2) its treatment of interests (for example, common stock, a partnership interest or other means of exerting influence) in other entities, for example consolidation or use of the equity or cost methods of accounting. The accounting policy may also address the accounting treatment for intercompany accounts and transactions, noncontrolling interest, and the income statement treatment in consolidation for issuances of stock by a subsidiary.

Disclosure of accounting policy for reporting when there is a substantial doubt about an entity's ability to continue as a going concern for a reasonable period of time (generally a year from the balance sheet date). Disclose: (a) pertinent conditions and events giving rise to the assessment of substantial doubt about the entity's ability to continue as a going concern for a reasonable period of time, (b) the possible effects of such conditions and events, (c) management's evaluation of the significance of those conditions and events and any mitigating factors, (d) possible discontinuance of operations, (e) management's plans (including relevant prospective financial information), and (f) information about the recoverability or classification of recorded asset amounts or the amounts or classification of liabilities. If management's plans alleviate the substantial doubt about the entity's ability to continue as a going concern, disclosure of the principal conditions and events that initially raised the substantial doubt about the entity's ability to continue as a going concern would be expected to be considered. Disclose whether operations for the current or prior years generated sufficient cash to cover current obligations, whether waivers were obtained from creditors relating to the company's default under the provisions of debt agreements and possible effects of such conditions and events, such as: whether there is a possible need to obtain additional financing (debt or equity) or to liquidate certain holdings to offset future cash flow deficiencies. Disclose appropriate parent company information when parent is dependent upon remittances from subsidiaries to satisfy its obligations.
