Note 1—Nature of Business

Organization and operations — Primoris Services Corporation is a holding company of various construction and product engineering subsidiaries. The Company’s underground and directional drilling operations install, replace and repair natural gas, petroleum, telecommunications and water pipeline systems, including large diameter pipeline systems. The Company’s industrial, civil and engineering operations build and provide maintenance services to industrial facilities including power plants, petrochemical facilities, and other processing plants; construct multi-level parking structures; and engage in the construction of highways, bridges and other environmental construction activities. The Company is incorporated in the State of Delaware, and its corporate headquarters is located at 2100 McKinney Avenue, Suite 1500, Dallas, Texas 75201.

Reportable Segments — Through the end of the year 2016, the Company segregated its business into three reportable segments: the Energy segment, the East Construction Services segment and the West Construction Services segment. In the first quarter 2017, the Company changed its reportable segments in connection with a realignment of the Company’s internal organization and management structure. The segment changes during the quarter reflect the focus of our chief operating decision maker (“CODM”) on the range of services we provide to our end user markets. Our CODM regularly reviews the operating and financial performance of our business units based on these segments.

The current reportable segments include the Power, Industrial and Engineering (“Power”) segment, the Pipeline and Underground (“Pipeline”) segment, the Utilities and Distribution (“Utilities”) segment and the Civil segment.  Segment information for prior periods have been restated to conform to the new segment presentation.  See Note 18 – “Reportable Segments” for a brief description of the reportable segments and their operations.

The classification of our business unit revenues and gross profit for segment reporting purposes can at times require judgment on the part of management. Our business units may perform services across industries or perform joint services for customers in multiple industries. To determine reportable segment gross profit, certain allocations, including allocations of shared and indirect costs, such as facility costs, equipment costs and indirect operating expenses were made.

The following table lists the Company’s primary business units and their reportable segment:

The Company owns a 50% interest in two separate joint ventures, both formed in 2015.  The Carlsbad Power Constructors joint venture (“Carlsbad”) is engineering and constructing a gas-fired power generation facility, and the “ARB Inc. & B&M Engineering Co.” joint venture (“Wilmington”) is also engineering and constructing a gas-fired power generation facility.  Both projects are located in the Southern California area.  The joint venture operations are included as part of the Power division of the Power segment.  As a result of determining that the Company is the primary beneficiary of the two variable interest entities (“VIEs”), the results of the Carlsbad and Wilmington joint ventures are consolidated in the Company’s financial statements.  Both projects are expected to be completed in 2018.  Financial information for the joint ventures is presented in Note 11 – “Noncontrolling Interests”.

On January 29, 2016, the Company acquired the net assets of Mueller Concrete Construction Company (“Mueller”) for $4.1 million, and on November 18, 2016, the Company acquired the net assets of Northern Energy & Power (“Northern”) for $6.8 million.  On May 26, 2017, the Company acquired the net assets of Florida Gas Contractors (“FGC”) for $37.7 million, on May 30, 2017 the Company acquired certain engineering assets for approximately $2.3 million, and on June 16, 2017, the Company acquired the net assets of Coastal Field Services (“Coastal”) for $27.5 million.  Both Mueller and FGC operations are included in the Utilities segment, Northern operations are included in the Power segment, and Coastal operations are included in the Pipeline segment.  See Note 7— “Business Combinations”.

Unless specifically noted otherwise, as used throughout these consolidated financial statements, “Primoris”, “the Company”, “we”, “our”, “us” or “its” refers to the business, operations and financial results of the Company and its wholly-owned subsidiaries.

Note 2—Basis of Presentation

Interim consolidated financial statements — The interim condensed consolidated financial statements for the three and six month periods ended June 30, 2017 and 2016 have been prepared in accordance with Rule 10-01 of Regulation S-X of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). As such, certain disclosures, which would substantially duplicate the disclosures contained in the Company’s Annual Report on Form 10-K, filed on February 28, 2017, which contains the Company’s audited consolidated financial statements for the year ended December 31, 2016, have been omitted. 

This Second Quarter 2017 Report should be read in concert with the Company’s most recent Annual Report on Form 10-K. The interim financial information is unaudited.  In the opinion of management, the interim information includes all adjustments (consisting of normal recurring adjustments) necessary for the fair presentation of the interim financial information. 

Revenue recognition

Fixed-price contracts — Historically, a substantial portion of the Company’s revenue has been generated under fixed-price contracts.  For fixed-price contracts, the Company recognizes revenues primarily using the percentage-of-completion method, which may result in uneven and irregular results. In the percentage-of-completion method, estimated contract values, estimated cost at completion and total costs incurred to date are used to calculate revenues earned. Unforeseen events and circumstances can alter the estimate of the costs and potential profit associated with a particular contract.  Total estimated costs, and thus contract revenues and income, can be impacted by changes in productivity, scheduling, the unit cost of labor, subcontracts, materials and equipment. Additionally, external factors such as weather, client needs, client delays in providing permits and approvals, labor availability, governmental regulation and politics may affect the progress of a project’s completion and thus the timing of revenue recognition.  To the extent that original cost estimates are modified, estimated costs to complete increase, delivery schedules are delayed, or progress under a contract is otherwise impeded, cash flow, revenue recognition and profitability from a particular contract may be adversely affected.

Other contract forms — The Company also uses unit price, time and material, and cost reimbursable plus fee contracts.  For these jobs, revenue is recognized primarily based on contractual terms. Generally, time and material and cost reimbursement contract revenues are recognized on an input basis, based on labor hours incurred and on purchases made.  Unit price contracts generally recognize revenue on an output based measurement such as the completion of specific units at a specified unit price.

The Company considers unapproved change orders to be contract variations for which customers have not agreed to both scope and price.  Costs associated with unapproved change orders are included in the estimated cost to complete and are treated as project costs as incurred. The Company will recognize revenue if it is probable that the contract price will be adjusted and can be reliably estimated.  Unapproved change orders involve the use of estimates, and it is reasonably possible that revisions to the estimated costs and recoverable amounts may be required in future reporting periods to reflect changes in estimates or final agreements with customers.

The Company considers claims to be amounts it seeks, or will seek, to collect from customers or others for customer-caused changes in contract specifications or design, or other customer-related causes of unanticipated additional contract costs on which there is no agreement with customers. Claims can also be caused by non-customer-caused changes, such as weather delays or rain.  Costs associated with claims are included in the estimated costs to complete the contracts and are treated as project costs when incurred.  Claims are included in revenue to the extent the related costs have been incurred, realization is probable, and amounts can be reliably estimated.  Revenue in excess of contract costs from claims is recognized when an agreement is reached with customers as to the value of the claims, which in some instances may not occur until after completion of work under the contract.

At any time, if an estimate of total contract cost indicates a loss on a contract, the projected loss is recognized in full at that time and recognized as an “accrued loss provision” which is included in the accrued expenses and other current liabilities amount on the balance sheet. For fixed price contracts, as the percentage-of-completion method is used to calculate revenues, the accrued loss provision is changed so that the gross profit for the contract remains zero in future periods. If we anticipate that there will be a loss for unit price or cost reimbursable contracts, the projected loss is recognized in full at that time.

Changes in job performance, job conditions and estimated profitability, including those arising from final contract settlements, may result in revisions to costs and income. These revisions are recognized in the period in which the revisions are identified.

In all forms of contracts, the Company estimates its collectability of contract amounts at the same time that it estimates project costs.  If the Company anticipates that there may be issues associated with the collectability of the full amount calculated as revenues, the Company may reduce the amount recognized as revenue to reflect the uncertainty associated with realization of the eventual cash collection. For example, when a cost reimbursable project exceeds the client’s expected budget amount, the client frequently requests an adjustment to the final amount. Similarly, some utility clients reserve the right to audit costs for significant periods after performance of the work. In these situations, the Company may choose to defer recognition of revenue until the client pays for the services.

The caption “Costs and estimated earnings in excess of billings” in the Consolidated Balance Sheets represents unbilled receivables which arise when revenues have been recorded but the amount will not be billed until a later date.  Balances represent:  (a) unbilled amounts arising from the use of the percentage-of-completion method of accounting which may not be billed under the terms of the contract until a later date or project milestone; (b) incurred costs to be billed under cost reimbursement type contracts; (c) amounts arising from routine lags in billing; or (d) the revenue associated with unapproved change orders or claims when realization is probable and amounts can be reliably determined.  For those contracts in which billings exceed contract revenues recognized to date, the excess amounts are included in the caption “Billings in excess of costs and estimated earnings”.

In accordance with applicable terms of certain construction contracts, retainage amounts may be withheld by customers until completion and acceptance of the project.  Some payments of the retainage may not be received for a significant period after completion of our portion of a project.  In some jurisdictions, retainage amounts are deposited into an escrow account.

Significant revisions in contract estimates — Revenue recognition is based on the percentage-of-completion method for firm fixed-price contracts. Under this method, the costs incurred to date as a percentage of total estimated costs are used to calculate revenue. Total estimated costs, and thus contract revenues and margin, are impacted by many factors, which can cause significant changes in estimates during the life cycle of a project.

For projects that were in process at the end of the prior year or a prior quarter, there can be a difference in revenues and profits that would have been recognized in the prior year or prior quarter had current estimates of costs to complete been used at the end of the prior year or prior quarter.

Customer concentration — The Company operates in multiple industry segments encompassing the engineering and construction of commercial, industrial and public works infrastructure assets throughout primarily the United States. Typically, the top ten customers in any one calendar year generate revenues in excess of 50% of total revenues; however, the group that comprises the top ten customers varies from year to year.

During the three and six months ended June 30, 2017, revenues generated by the top ten customers were approximately $330.2 million and $713.5 million, respectively, which represented 52.3% and 59.8%, respectively, of total revenues during the period. During the periods, two large pipeline projects represented 11.0% and 19.2% of total revenues, respectively and Texas Department of Transportation (“TXDOT”) represented 10.6% and 10.5% of total revenues, respectively.

During the three and six months ended June 30, 2016, revenues generated by the top ten customers were $263.0 million and $533.0 million, respectively, which represented 57.7% and 60.1%, respectively, of total revenues during the period.  During the periods, a Louisiana petrochemical project represented 11.3% and 12.4% of total revenues, respectively and TXDOT represented 10.2% and 11.8% of total revenues, respectively.

At June 30, 2017, approximately 11.7% of the Company’s accounts receivable were due from one customer, and that customer provided 8.8% of the Company’s revenues for the six months ended June 30, 2017. In addition, of total accounts receivable, approximately 11.0% are from one customer with whom the Company is currently in dispute resolution. See Note 17 – “Commitments and Contingencies”.

At June 30, 2016, approximately 15.6% of the Company’s accounts receivable were due from one customer, and that customer provided 12.4% of the Company’s revenues for the six months ended June 30, 2016. In addition, approximately 16.0% of total accounts receivable at June 30, 2016 were in dispute resolution.

Multiemployer plans — Various subsidiaries are signatories to collective bargaining agreements.  These agreements require that the Company participate in and contribute to a number of multiemployer benefit plans for its union employees at rates determined by the agreements. The trustees for each multiemployer plan determine the eligibility and allocations of contributions and benefit amounts, determine the types of benefits, and administer the plan. Federal law requires that if the Company were to withdraw from an agreement, it would incur a withdrawal obligation. The potential withdrawal obligation may be significant. In accordance with Generally Accepted Accounting Principles (“GAAP”), any withdrawal liability would be recorded when it is probable that a liability exists and can be reasonably estimated.

Inventory and uninstalled contract materials — Inventory consists of expendable construction materials and small tools that will be used in construction projects and is valued at the lower of cost, using first-in, first-out method, or at net realizable value. Uninstalled contract materials are certain job specific materials not yet installed, primarily for highway construction projects, which are valued using the specific identification method relating the cost incurred to a specific project. In most cases, the Company is able to invoice a state agency for the materials, but title will not pass to the state agency until the materials are installed.

Note 3—Recent Accounting Pronouncements

In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers (Topic 606)”, with several clarifying updates issued during 2016. The new standard is effective for reporting periods beginning after December 15, 2017. The new standard will supersede all current revenue recognition standards and guidance.  Revenue recognition will occur when promised goods or services are transferred to customers in amounts that reflect the consideration to which the company expects to be entitled to in exchange for those goods or services. The mandatory adoption will require new qualitative and quantitative disclosures about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments, information about contract balances and performance obligations, and assets recognized from costs incurred to obtain or fulfill a contract. The standard permits the “modified retrospective method”, which requires prospective application of the new standard as a cumulative-effect adjustment. The Company expects to adopt this new standard using the modified retrospective method that will result in a cumulative-effect adjustment to retained earnings as of the date of adoption.  The adoption will only apply to customer contracts that are not substantially complete as of January 1, 2018.

The Company is currently evaluating the impact of adopting the standard on the Company’s financial position, results of operations, cash flows and related disclosures.  Although it is early in our evaluation process, we do not expect Topic 606 to have a material impact on our financial statements, though internal documentation and record keeping may be significantly impacted.  The impact to our results is not believed to be material because Topic 606 generally supports the recognition of revenue over time under the cost-to-cost method for the majority of our contracts, which is consistent with our current percentage of completion revenue recognition model.  In most of our fixed price contracts, the customer typically controls the work in process as evidenced either by contractual termination clauses or by our rights to payment for work performed to date to deliver services that do not have an alternative use to us. 

The Company does not expect the new standard to materially affect the total revenue that can be recognized over the life of a construction project; however, the revenue recognized on a quarterly basis during the construction period may change. We believe that Topic 606 is likely to be more impactful to certain of our lump sum projects as a result of the following potential changes from our current practices:

We do not expect Topic 606 to have a material impact on our consolidated balance sheets, though we expect certain reclassifications among financial statement accounts to align with the new standard.  We also expect significant expanded disclosures relating to revenue recognized during each period.

In February 2016, the FASB issued ASU 2016-02 “Leases (Topic 842)”. The ASU will require recognition of operating leases with lease terms of more than twelve months on the balance sheet as both assets for the rights and liabilities for the obligations created by the leases. The ASU will require disclosures that provide qualitative and quantitative information for the lease assets and liabilities recorded in the financial statements. The guidance is effective for fiscal years beginning after December 15, 2018. The Company is reviewing the impact of the ASU and will establish procedures to adopt the ASU.

In March 2016, the FASB issued ASU 2016-09 “Compensation — Stock Compensation (Topic 718) — Improvements to Employee Share-Based Payment Accounting”. The ASU modifies the accounting for excess tax benefits and tax deficiencies associated with share-based payments by requiring that excess tax benefits or deficiencies be included in the income statement rather than in equity.  Additionally, the tax benefits for dividends on share-based payment awards will also be reflected in the income statement. As a result of these modifications, the ASU requires that the tax-related cash flows resulting from share-based payments will be shown on the cash flow statement as operating activities rather than as financing activities. The Company adopted the ASU as of January 1, 2017, which did not have a material impact on the Company’s consolidated financial statements.

In January 2017, the FASB issued ASU 2017-01, "Business Combinations (Topic 805): Clarifying the Definition of a Business" which changes the definition of a business to assist entities with evaluating when a set of transferred assets and activities is a business. ASU 2017-01 requires an entity to evaluate if substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets; if so, the set of transferred assets and activities is not a business. ASU 2017-01 is effective for interim and annual reporting periods beginning after December 15, 2017. The Company does not expect the adoption of ASU 2017-01 to have an impact on its financial position, results of operations or cash flows.

In January 2017, the FASB issued ASU 2017-04, "Simplifying the Test for Goodwill Impairment". ASU 2017-04 removes the second step of the goodwill impairment test, which requires a hypothetical purchase price allocation. A goodwill impairment will now be the amount by which a reporting unit's carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. ASU 2017-04 is effective for interim and annual reporting periods beginning after December 15, 2019 and will be applied prospectively. The Company does not expect the adoption of ASU 2017-04 to have an impact on its financial position, results of operations or cash flows.

In May 2017, the FASB issued ASU 2017-09, “Compensation — Stock Compensation (Topic 718) — Scope of Modification Accounting”.  The ASU amends the scope of modification accounting for share-based payment arrangements.  The amendments in the ASU provide guidance on types of changes to the terms or conditions of share-based payment awards would be required to apply modification accounting under ASC 718, “Compensation — Stock Compensation”.  The ASU is effective for interim and annual reporting periods beginning after December 15, 2017 with early adoption permitted. The Company does not expect the adoption of ASU 2017-09 to have an impact on its financial position, results of operations or cash flows.

Note 4—Fair Value Measurements

ASC Topic 820, “Fair Value Measurements and Disclosures” defines fair value, establishes a framework for measuring fair value in GAAP and requires certain disclosures about fair value measurements.  ASC Topic 820 addresses fair value GAAP for financial assets and financial liabilities that are re-measured and reported at fair value at

each reporting period and for non-financial assets and liabilities that are re-measured and reported at fair value on a non-recurring basis.

In general, fair values determined by Level 1 inputs use quoted prices (unadjusted) in active markets for identical assets or liabilities. Fair values determined by Level 2 inputs use data points that are observable such as quoted prices, interest rates and yield curves. Fair values determined by Level 3 inputs are “unobservable data points” for the asset or liability and include situations where there is little, if any, market activity for the asset or liability.

The following table presents, for each of the fair value hierarchy levels identified under ASC Topic 820, the Company’s financial assets and liabilities that are required to be measured at fair value at June 30, 2017 and December 31, 2016:

Other financial instruments of the Company not listed in the table consist of accounts receivable, accounts payable and certain accrued liabilities.  These financial instruments generally approximate fair value based on their short-term nature.  The carrying value of the Company’s long-term debt approximates fair value based on comparison with current prevailing market rates for loans of similar risks and maturities. 

The following table provides changes to the Company’s contingent consideration liability Level 3 fair value measurements during the six months ended June 30, 2017 and 2016:

On a quarterly basis, the Company assesses the estimated fair value of the contractual obligation to pay the contingent consideration and any changes in estimated fair value are recorded as a non-operating charge in the Company’s statement of income.  Fluctuations in the fair value of contingent consideration are impacted by two unobservable inputs, management’s estimate of the probability of the acquired company meeting the contractual operating performance target and the estimated discount rate (a rate that approximates the Company’s cost of capital). Significant changes in either of those inputs in isolation would result in a different fair value measurement.  Generally, a change in the assumption of the probability of meeting the performance target is accompanied by a directionally similar change in the fair value of contingent consideration liability, whereas a change in assumption used of the estimated discount rate is accompanied by a directionally opposite change in the fair value of contingent consideration liability.

Note 5—Accounts Receivable

Note 7 — Business Combinations

On January 29, 2016, the Company’s subsidiary, Primoris AV, acquired certain assets and liabilities of Mueller Concrete Construction Company for $4.1 million. The purchase was accounted for using the acquisition method of accounting.  During the second quarter of 2016, the Company finalized its estimate of fair value of the acquired assets of Mueller, which included $2.0 million of fixed assets, $2.0 million of goodwill and $0.1 million of inventory. Mueller operates as a division of Primoris AV, within the Utilities segment.  Goodwill largely consists of expected benefits from providing foundation expertise for Primoris AV’s construction efforts in underground line work, substations and telecom/fiber.  Goodwill also includes the value of the assembled workforce that the Mueller acquisition provides to the Primoris AV business.  Based on the current tax treatment, goodwill and other intangible assets will be deductible for income tax purposes over a fifteen-year period.

On June 24, 2016, the Company’s subsidiary, Vadnais Trenchless, purchased property, plant and equipment from Pipe Jacking Unlimited, Inc., consisting of specialty directional drilling and tunneling equipment for $13.4 million in cash. The Company determined this purchase did not meet the definition of a business as defined under ASC 805. The estimated fair value of the equipment was equal to the purchase price.  The Company believes the purchase of the equipment will aid in the Company’s pipeline construction projects and enhance the work provided to our utility clients.

On November 18, 2016, the Company’s subsidiary, Primoris AV, acquired certain assets and liabilities of Northern Energy & Power for $6.8 million.  The acquired business unit name was changed to Primoris Renewable Energy (“PRE”).  PRE operates in the Power segment and serves the renewable energy sector with a specific focus on solar photovoltaic installations in the United States.  The purchase was accounted for using the acquisition method of accounting.  During the second quarter of 2017, the Company finalized its estimated fair value of the acquired assets of

PRE, which resulted in a $0.1 million reduction in goodwill compared to amounts previously disclosed.  The allocation of the total purchase price included fixed assets of $0.1 million; intangible assets of $3.0 million; and goodwill of $3.7 million.  Goodwill largely consists of synergies expected from expanded operations as well as the value of the assembled workforce that PRE provides.  Based on the current tax treatment, goodwill will be deductible for income tax purposes over a fifteen-year period. 

On May 26, 2017, the Company acquired certain assets of Florida Gas Contractors, a utility contractor specializing in underground natural gas infrastructure, for approximately $33.0 million in cash.  In addition, the sellers could receive a contingent earnout amount of up to $1.5 million over a one-year period ending May 26, 2018, based on the achievement of certain operating targets.  The estimated fair value of the potential contingent consideration on the acquisition date was $1.2 million.  FGC operates in the Utilities segment and expands the Company’s presence in the Florida and Southeast markets.  The purchase was accounted for using the acquisition method of accounting.  The preliminary allocation of the total purchase price consisted of $4.8 million of fixed assets; $4.2 million of working capital; $10.5 million of intangible assets; and $14.7 million of goodwill. In connection with the FGC acquisition, the Company also paid $3.5 million to acquire certain land and buildings.  Goodwill associated with the FGC acquisition principally consists of expected benefits from providing expertise for the Company’s construction efforts in the underground utility business as well as the expansion of the Company’s geographic presence.  Goodwill also includes the value of the assembled workforce that the FGC acquisition provides to the Company.  Based on the current tax treatment, goodwill will be deductible for income tax purposes over a fifteen-year period.

On May 30, 2017, the PD&C acquired certain engineering assets for approximately $2.3 million in cash.  PD&C operates in the Power segment and the acquisition futher enhances its ability to provide quality service for engineering and design projects.  The purchase was accounted for using the acquisition method of accounting.  The preliminary allocation of the total purchase price consisted of $0.2 million of fixed assets and $2.1 million of intangible assets.

On June 16, 2017, the Company acquired certain assets and liabilities of Coastal Field Services for approximately $27.5 million in cash.  Coastal provides pipeline construction and maintenance, pipe and vessel coating and insulation, and integrity support services for companies in the oil and gas industry.  Coastal operates in the Pipeline segment and increases the Company’s market share in the Gulf Coast energy market.  The purchase was accounted for using the acquisition method of accounting.  The preliminary allocation of the total purchase price consisted of $4.0 million of fixed assets; $4.8 million of working capital; $9.9 million of intangible assets and $8.8 million of goodwill. Goodwill associated with the Coastal acquisition principally consists of expected benefits from providing expertise for the Company’s expansion of services in the pipeline construction and maintenance business.  Goodwill also includes the value of the assembled workforce that the Coastal acquisition provides to the Company.  Based on the current tax treatment, goodwill will be deductible for income tax purposes over a fifteen-year period.

Supplemental Unaudited Pro Forma Information for the three and six months ended June 30, 2017 and 2016

The following pro forma information for the three and six months ended June 30, 2017 and 2016 presents the results of operations of the Company as if the acquisitions had occurred at the beginning of 2016. The supplemental pro forma information has been adjusted to include:

The pro forma results are presented for illustrative purposes only and are not necessarily indicative of, or intended to represent, the results that would have been achieved had the various acquisitions been completed on January

1, 2016.  For example, the pro forma results do not reflect any operating efficiencies and associated cost savings that the Company might have achieved with respect to the acquisitions.

Note 8—Goodwill and Intangible Assets

Goodwill by segment was recorded as follows:

At June 30, 2017 and December 31, 2016, intangible assets totaled $51.2 million and $32.8 million, respectively, net of amortization.  The table below summarizes the intangible asset categories, amounts and the average amortization periods, which are on a straight-line basis:

Amortization expense of intangible assets was $1.9 million and $1.6 million for the three months ended June 30, 2017 and 2016, respectively and amortization expense for the six months ended June 30, 2017 and 2016 was $3.6 million and $3.2 million, respectively. Estimated future amortization expense for intangible assets is as follows:

Note 9—Accounts Payable and Accrued Liabilities

At June 30, 2017 and December 31, 2016, accounts payable were $134.1 million and $168.1 million, respectively.  These balances included retention amounts for the same periods of approximately $10.7 million and $10.6 million, respectively.  The retention amounts are due to subcontractors and have been retained pending contract completion and customer acceptance of jobs.

The following is a summary of accrued expenses and other current liabilities:
