The December 31, 2017 condensed consolidated balance sheet2018 Condensed Consolidated Balance Sheet data herein was derived from audited financial statements, but as discussed above, does not include all disclosures required by GAAP. Interim results may be subject to significant seasonal variations and the results of operations for the three and six months ended June 30, 2018quarters presented are not necessarily indicative of the results expected for the full year or subsequent quarters. Values presented within tables, excluding per share data, are in thousands.
Principles of Consolidation—The accompanying Condensed Consolidated Financial Statements reflect all wholly owned subsidiaries and those entities the Company is required to consolidate. See the “Consolidated 50% Owned Subsidiaries” and “Construction Joint Ventures” section of this footnote for further discussion of the Company’s consolidation policy for those entities that are not wholly owned. In the opinion of management, all adjustments, consisting only of normal recurring adjustments, considered necessary for a fair presentation have been included. All significant intercompany accounts and transactions have been eliminated in consolidation.
Consolidated 50% Owned Subsidiaries—The accompanying Condensed Consolidated Financial Statements include the accounts of two subsidiaries in which the Company has 50% ownership interest and exercises control over such entities. Therefore, the Company has consolidated these two entities. Both subsidiaries have individual provisions which, under circumstances that are certain to occur, obligate the Company to purchase each partner’s 50% interests. The Company has classified these obligations as mandatorily redeemable and has recorded a liability in “Members’ interest subject to mandatory redemption and undistributed earnings” on the Condensed Consolidated Balance Sheets. Each partner’s portion of net income (loss) is reflected in the Condensed Consolidated Statements of Operations line item “Other operating expense, net”.
Construction Joint Ventures—In the ordinary course of business, the Company executes specific projects and conducts certain operations through joint venture arrangements (referred to as “joint ventures”). The Company has various ownership interests in these joint ventures, with such ownership typically proportionate to the Company’s decision making and distribution rights.
Each joint venture is assessed at inception and on an ongoing basis as to whether it qualifies as a Variable Interest Entity (“VIE”) under the consolidations guidance in ASC Topic 810. If at any time a joint venture qualifies as a VIE, the Company performs a qualitative assessment to determine whether the Company is the primary beneficiary of the VIE and therefore needs to consolidate the VIE.
If the Company determines it is not the primary beneficiary of the VIE or only has the ability to significantly influence, rather than control the joint venture, it is not consolidated. The Company accounts for unconsolidated joint ventures using a pro-rata basis in the Condensed Consolidated Statements of Operations and as a single line item (“Receivables from and equity in construction joint ventures”) in the Condensed Consolidated Balance Sheets. This method is a permissible modification of the equity method of accounting which is a common practice in the construction industry.


Use of Estimates
Estimates—The preparation of the accompanying condensed consolidated financial statementsCondensed Consolidated Financial Statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Certain of the Company’s accounting policies require higher degrees of judgment than others in their application. These include the recognition of revenue and earnings from construction contracts over time and the valuation of long-term assets, income taxes, and purchase accounting, includinggoodwill, other intangibles and goodwill.income taxes. Management continually evaluates all of its estimates and judgments based on available information and experience; however, actual results could differ from these estimates.
Significant Accounting Policies
TheReclassification—Reclassifications have been made to historical financial data on the Company’s significant accounting policies are more fully described in Note 1 of the Notes toCondensed Consolidated Financial Statements into conform to the 2017 Form 10-K. There have been no material changes to significant accounting policies since December 31, 2017.
Principles of Consolidation
The accompanying condensed consolidated financial statements include the accounts of subsidiaries and construction joint ventures in which the Company has 50% or greater ownership interest or otherwise exercises control over such entities. For investments in construction joint ventures that are not wholly-owned, but where the Company exercises control, the equity held by the remaining owners and their portions of net income are reflected in the balance sheet line item “Noncontrolling interests” in “Equity” and the statement of operations line item “Noncontrolling interests in earnings,” respectively. For investments in subsidiaries that are not wholly-owned, but where the Company exercises control and where the Company has a mandatorily redeemable interest, the equity held by the remaining owners and their portion of net income (loss) is reflected in the balance sheet line item “Members' interest subject to mandatory redemption and undistributed earnings” and the statement of operations line item “Other operating expense, net” respectively. All significant intercompany accounts and transactions have been eliminated in consolidation. Company’s current year presentation.
Where the Company is a noncontrolling joint venture partner, and is otherwise not required to consolidate the joint venture entity, its share of the earnings of such construction joint venture is accounted for on a pro rata basis in the condensed consolidated statements of operations and as a single line item (“Receivables from and equity in construction joint ventures”) in the condensed consolidated balance sheets. This method is a permissible modification of the equity method of accounting which is a common practice in the construction industry.


Revenue Recognition
Heavy Civil Construction
Revenue Recognition—The Company engages in various types of heavy civil construction projects principally for public (government) owners. Revenues are recognized as performance obligations are satisfied over time (also(formerly known as percentage-of-completion method), measured byusing the ratio of costs incurred up to a given date to estimated total costs for each contract. This cost to cost measure is used because management considers it to be the best available measure of progress on these contracts. Contract costs include all direct material, labor, subcontract and other costs and those indirect costs determined to relate to contract performance, such as indirect salaries and wages, equipment repairs and depreciation, insurance and payroll taxes. Administrative and general expenses are charged to expense as incurred. Provisions for estimated losses on uncompleted contracts are made in the period in which such losses are determined. Changes in job performance, job conditions, estimated profitability and associated change orders and claims, including those changes arising from contract penalty provisions and final contract settlements, may result in revisions to costs and income and are recognized in the period in which the revisions are determined.
Residential Construction
Residential construction revenueChange orders, claims and related profitincentives are recognized when construction ongenerally not distinct from the concrete foundation unit is completed (i.e.existing contract due to the significant integration service provided in the context of the contract and are accounted for as a modification of the existing contract and performance obligation. Change orders may include changes in specifications or designs, manner of performance, facilities, equipment, materials, sites and period of completion of the work. Either the Company or its customers may initiate change orders. Change orders that are unapproved as to both price and scope are evaluated as claims. The Company estimates variable consideration for a performance obligation at the most likely amount to which the Company expects to be entitled (or the most likely amount the Company expects to incur in the case of liquidated damages), at a point in time). The time from starting construction to finishing is typically less than one month.
Recently Adopted Accounting Pronouncements
In May 2014,utilizing estimation methods that best predict the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-9, “Revenue from Contracts with Customers”, which provides a single comprehensive accounting standard for revenue recognition for contracts with customers and supersedes current industry-specific guidance, including ASC 605-35. The new standard requires companies to recognize revenue when controlamount of promised goods or services is transferred to customers at an amount that reflects the consideration to which the company expectsCompany will be entitled (or will be incurred in the case of liquidated damages). The Company includes variable consideration in the estimated transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur or when the uncertainty associated with the variable consideration is resolved. The Company’s estimates of variable consideration and determination of whether to include estimated amounts in transaction price are based largely on an assessment of its anticipated performance and all information (historical, current and forecasted) that is reasonably available to the Company.
The Company considers claims to be entitledamounts in exchange for the goods or services. The new model requires companies to identify contractual performance obligations and determine whether revenue should be recognized at a point in time or over time (formerly known as percentage-of-completion method) for eachexcess of these obligations. The new standard also significantly expands disclosure requirements regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers.
We adopted the new standard on January 1, 2018, for all contracts using the modified retrospective methodapproved contract prices that is described in the following paragraph. The adoption of the new revenue standard had no material impact on our condensed consolidated financial statements as it did not require a change in revenue recognition for either of our segments. As such, comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods.
We implemented the new standard's transitional rules as follows: ASC 606-10-65-1 permits the omission of prior-period information about our performance obligations that were not complete at the time of our new adoption of the new standard. Further, rather than applying the new recognition policy on a contract by contract bases, ASC 606-10-32-18 allows the new standard to be applied against a portfolio of contracts (or performance obligations) with similar characteristics. As the majority of our significant contracts are with government entities and major homebuilders that utilize contracts of a similar structure and nature, this new accounting policy will not yield a material difference for the Company than applying the guidanceseeks to collect from its customers or others for customer-caused delays, errors in specifications and designs, contract terminations, change orders that are either in dispute or are unapproved as to both scope and price, or other causes of unanticipated additional contract costs. The effect of variable consideration on a contract by contract basis.
In addition to the foregoing, ASC 606-10-32-18 allows entities to waive the requirement to adjust the consideration amount for the effects of a significant financing component if the entity expects, at contract inception, that the period between its fulfillment of the performance obligation and receipt of the customer's payment is less than one year. Further ASC 606-10-32-2A allows entities to make an accounting policy election to exclude taxes assessed by and collected on behalf of government authorities from the transaction price allocatedof a performance obligation is recognized as an adjustment to revenue on a cumulative catch-up basis. To the extent unapproved change orders and claims reflected in transaction price (or excluded from transaction price in the case of liquidated damages) are not resolved in the Company’s favor, or to the performance obligation. We have historically excluded such amounts from our revenues and will continue to do so under the new revenue standard.extent incentives reflected in transaction price are not earned, there could be reductions in, or reversals of, previously recognized revenue.
See Note 3 for additional discussion of our revenue recognition accounting policies and expanded disclosures required by the new standard.


Recently Issued Accounting Pronouncements
In February 2016, the FASB issued its new lease accounting guidance in ASU No. 2016-2, “Leases” (Topic 842). Under the new guidance, lessees will be required to recognize for all leases (with the exception of short-term leases) a lease liability, whichThe Company has projects that it is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis, and a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. The standard is effective for us for interim and annual reporting periods beginning after December 15, 2018. In January 2018, the FASB issued an exposure draft proposing an amendment to the standard that, if approved, would permit companies the option to apply the provisions of the new lease standard either prospectively as of the effective date, without adjusting comparative periods presented, or using a modified retrospective transition applicable to all prior periods presented. If approved, we intend to apply the new guidance prospectively to leases that exist and those entered into on or after January 1, 2019 without adjusting comparative periods in the financial statements. We are assessing the potential impactprocess of negotiating, or awaiting final approval of, unapproved change orders and claims with its customers. The Company is proceeding with its contractual rights to recoup additional costs incurred from its customers based on our Financial Statements and related disclosures.
2.Tealstone Acquisition
General
On April 3, 2017, the Company consummated the acquisition (the “Tealstone Acquisition”) of 100% of the outstanding stock of Tealstone Residential Concrete, Inc. and Tealstone Commercial, Inc. (collectively, “Tealstone”) from the stockholders thereof (the “Sellers”) for consideration consisting of $55,000,000 in cash, 1,882,058 shares of the Company’s common stock, and $5,000,000 of promissory notes issued to the Sellers. In addition, the Company will make $2,426,000 and $7,500,000 of deferred cash payments on the second and third anniversaries of the closing date, respectively, and up to an aggregate of $15,000,000 in earn-out payments if specified financial performance levels are achieved (subject to annual maximums) on each of the first, second, third and fourth anniversaries of the closing date to continuing Tealstone management or their affiliates. Tealstone focuses on concrete construction of residential foundations, parking structures, elevated foundations and other concretecompleting work for leading homebuilders, multi-family developers and general contractors in both residential and commercial markets. This acquisition enables expansion into adjacent markets and diversification of revenue streams and customer base with higher margin work.
Supplemental Pro Forma Information (Unaudited)
The following unaudited pro forma condensed combined financial information (“the pro forma financial information”) gives effect to the acquisition of Tealstone by Sterling, accounted for as a business combination using the purchase method of accounting. The pro forma financial information reflects the Tealstone Acquisition and related events as if they occurred at the beginning of the period covered by the pro formas, and gives effect to pro forma events that are: directly attributable to the acquisition, factually supportable, and expected to have a continuing impact on the combined results of Sterling and Tealstone following the acquisition. The pro forma financial information includes adjustments to: (1) exclude transaction costs that were included in Sterling’s and Tealstone’s historical results and are expected to be non-recurring; and (2) include additional intangibles amortization and net interest expense associated with change orders, including change orders with pending change order pricing, or claims related to significant changes in scope which resulted in substantial delays and additional costs in completing the Tealstone Acquisition.

3.Revenue from Contracts with Customers
Performance Obligations
A performance obligation is a promise in a contract to transfer a distinct good or service to the customer, and is the unit of account in the new revenue standard. The contract transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied. The majority of our contracts have a single performance obligation as the promise to transfer the individual goods or services is not separately identifiable from other promises in the contracts and, therefore, not distinct. Some of our contracts have multiple performance obligations, most commonly due to the contract covering multiple phases of the product life cycle (design and construction). For contracts with multiple performance obligations, we allocate the contract transaction price to each performance obligation using our best estimate of the standalone selling price of each distinct good or service in the contract. The primary method used to estimate standalone selling price is the expected cost plus a margin approach, under which we forecast our expected costs of satisfying a performance obligation and then add an appropriate margin for that distinct good or service.
Performance Obligations Satisfied Over Time
Revenue for our Heavy Civil Construction segment contracts that satisfy the criteria for over time recognition (formerly known as percentage-of-completion method) is recognized as the work progresses. The majority of our revenue is derived from long-term, heavy civil construction contracts and projects that typically span between 12 to 36 months. Our heavy civil construction contractsreached, legal action will continue to be recognized over time because of the continuous transfer of control to the customer as all of the work is performed at the customer’s site and, therefore, the customer controls the asset as it is being constructed. This continuous transfer of control to the customer is further supported by clauses in the contract that allow the customer to unilaterally terminate the contract for convenience, pay us for costs incurred plus a reasonable profit and take control of any work in process. Under the new revenue standard, the cost-to-cost measure of progress continues to best depict the transfer of control of assets to the customer, which occurs as we incur costs. Contract costs include labor, material, and indirect costs. Revenue from products and services transferred to customers over time accounted for 83% and 84% of our revenue for the three and six months ended June 30, 2018, respectively. Revenue from products and services transferred to customers over time accounted for 85% and 91% of our revenue for the three and six months ended June 30, 2017, respectively.
Performance Obligations Satisfied at a Point in Time
Revenue for our Residential Construction segment contracts that do not satisfy the criteria for over time recognition is recognized at a point in time. Substantially all of our revenue recognized at a point in time is for work performed by our residential construction segment. Unlike our heavy civil construction segment that uses a cost-to-cost input measure for performance, the residential construction segment utilizes an output measure for performance based on the completion of a unit of work (e.g., foundation). The typical time frame for completion of a residential foundation is less than one month. Upon fulfillment of the performance obligation, the customer is provided an invoice (or equivalent) demonstrating transfer of control to the customer. We believe that point in time recognition remains appropriate for this segment and will continue to recognize revenues upon completion of the performance obligation and issuance of an invoice. Revenue from goods and services transferred to customers at a point in time accounted for 17% and 16% of our revenue for the three and six months ended June 30, 2018, respectively. Revenue from goods and services transferred to customers at a point in time accounted for 15% and 9% of our revenue for the three and six months ended June 30, 2017, respectively.taken.
Contract modifications are routine in the performance of ourthe Company’s contracts. Contracts are often modified to account for changes in the contract specifications or requirements. In most instances, contract modifications are for goods or services that are not distinct, and, therefore, are accounted for as part of the existing contract.
Assurance-type warranties are the only warranties provided by the Company and, as such, we dothe Company does not recognize revenue on warranty-related work. WeThe Company generally provideprovides a one to two year warranty for workmanship under ourits contracts when completed. Warranty claims historically have been insignificant.
Pre-contract costs are generally charged to expense as incurred, but in certain cases their recognition may be deferred if specific probability criteria are met. WeThe Company had no significant deferred pre-contract costs at June 30, 2018.2019.
Backlog

Residential Construction Revenue Recognition—Residential construction revenue and related profit are recognized when construction on the concrete foundation unit is completed (i.e., at a point in time). The time from starting construction to finishing is typically less than one month.
Leases—Effective January 1, 2019, the Company determines if an arrangement is a lease at inception. The operating lease right-of-use (“ROU”) assets are included within the Company’s other non-current assets and lease liabilities are included in current or non-current liabilities on the Company’s Condensed Consolidated Balance Sheets. Finance leases are included in property and equipment, current maturities of long-term debt, and long-term debt on the Company’s Condensed Consolidated Balance Sheets.
ROU assets represent the Company’s right to use, or control the use of, a specified asset for the lease term. Lease liabilities are the Company’s obligation to make lease payments arising from a lease, and are measured on a discounted basis. Operating lease ROU assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term on the commencement date. As most of the Company’s leases do not provide an implicit rate, the Company’s incremental borrowing rate was used based on the information available on the commencement date in determining the present value of lease payments. For future leases, the implied rate in the lease will be used to determine the present value. The operating lease ROU asset includes any lease payments made and initial direct costs incurred and excludes lease incentives. The lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for minimum lease payments continues to be recognized on a straight-line basis over the lease term.
Restricted cash—Restricted cash of approximately $3,200 and $3,900 is included in “Other current assets” on the Condensed Consolidated Balance Sheets at June 30, 2019 and December 31, 2018. This represents cash deposited by the Company into separate accounts and designated as collateral for standby letters of credit in the same amount in accordance with contractual agreements.
Recently Adopted Accounting Guidance
Leases—In February 2016, the Financial Accounting Standards Board (“FASB”) issued its new lease accounting guidance in ASU 2016-2, “Leases” (ASC 842). Under the new guidance, lessees are required to recognize all leases (with the exception of short-term leases) on the balance sheet. The Company adopted ASC 842 effective January 1, 2019 using the modified retrospective method. The new guidance has been applied to leases that exist or were entered into on or after January 1, 2019 without adjusting comparative periods in the financial statements. As an accounting policy, the Company has elected not to apply the recognition requirements to short-term leases (leases with terms of 12 months or less). Instead, the Company recognizes the lease payments in the Condensed Consolidated Statement of Operations on a straight-line basis over the lease term and variable lease payments in the period in which the obligation for those payments is incurred. The Company has elected to utilize the package of practical expedients that allows entities to not reassess 1) the classification of leases existing at the date of adoption 2) the initial direct costs for any existing leases and 3) whether any expired or existing contracts are or contain leases.
At January 1, 2019, the Company recorded an ROU asset, current maturity of operating lease liability and long-term operating lease liability of $13,600, $6,200 and $7,400, respectively on its Condensed Consolidated Balance Sheet, related to its existing operating leases. The adoption of this standard did not have a material impact on the Company’s Condensed Consolidated Statements of Operations. As of June 30, 2019, the weighted average remaining lease terms for the Company’s various operating leases extends out over the next 2.8 years. The weighted average discount rate used to determine the present value of the Company’s operating leases’ future payments was approximately 6.0%.


3.REVENUE FROM CONTRACTS WITH CUSTOMERS
Performance Obligations Satisfied Over Time—Revenue for the heavy civil construction segment contracts that satisfy the criteria for over time recognition is recognized as the work progresses. The majority of the revenue is derived from long-term, heavy civil construction contracts and projects that typically span between 12 months to 36 months. Revenue from products and services transferred to customers over time accounted for 86% and 84% of revenue for the three and six months ended June 30, 2019, respectively. Revenue from products and services transferred to customers over time accounted for 83% and 84% of revenue for the three and six months ended June 30, 2018, respectively.
Performance Obligations Satisfied at a Point in Time—Revenue for the residential construction segment contracts that do not satisfy the criteria for over time recognition is recognized at a point in time and utilizes an output measure for performance based on the completion of a unit of work (e.g., residential foundation). The typical time frame for completion of a residential foundation is less than one month. Revenue from products and services transferred to customers at a point in time accounted for 14% and 16% of revenue for the three and six months ended June 30, 2019, respectively. Revenue from products and services transferred to customers at a point in time accounted for 17% and 16% of revenue for the three and six months ended June 30, 2018, respectively.
BacklogOn June 30, 2018, we2019, the Company had $885 millionapproximately $909,000 of remaining performance obligations (which is also referred to as “backlog”) in ourits heavy civil construction segment, which we also refer to as backlog. We expectsegment. The Company expects to recognize approximately 70% of ourits backlog as revenue during the next twelve months, and the balance thereafter.


Contract Estimates
Accounting for long-term contracts and programs involves the use of various techniques to estimate total contract revenue and costs. For long-term contracts, we estimate the profit on a contract as the difference between the total estimated revenue and expected costs to complete a contract and recognize that profit over the life of the contract.
Contract estimates are based on various assumptions to project the outcome of future events that often span several years. These assumptions include labor productivity and availability, the complexity of the work to be performed, the cost and availability of materials and the performance of subcontractors. Changes in job performance, job conditions and estimated profitability, including those changes arising from contract penalty provisions and final contract settlements may result in revisions to costs and income and are recognized in the period in which the revisions are determined. Changes in estimated revenues and gross margin resulted in a net gainincrease of $0.3 millionapproximately $3,500 and $1.7 million$3,300 for the three and six months ended June 30, 2019, respectively, and a net increase of approximately $300 and $1,700 for the three and six months ended June 30, 2018, respectively, and a net charge of $1.8 million and $1.1 million for the three and six months ended June 30, 2017, respectively, included in “Operating income” on the condensed consolidated statementsCondensed Consolidated Statements of operations.Operations. Provisions for estimated losses on uncompleted contracts are made in the period in which such losses are determined.
Variable Consideration
Transaction—The transaction price for our contracts may include variable consideration, which includes increases to transaction price for approved and unapproved change orders, claims and incentives, and reductions to transaction price for liquidated damages. Change orders, claims and incentives are generally not distinct from the existing contract due to the significant integration service provided in the context of the contract and are accounted for as a modification of the existing contract and performance obligation. Change orders may include changes in specifications or designs, manner of performance, facilities, equipment, materials, sites and period of completion of the work. Either we or our customers may initiate change orders. Change orders that are unapproved as to both price and scope are evaluated as claims. We estimate variable consideration for a performance obligation at the most likely amount to which we expect to be entitled (or the most likely amount we expect to incur in the case of liquidated damages), utilizing estimation methods that best predict the amount of consideration to which we will be entitled (or will be incurred in the case of liquidated damages). We include variable consideration in the estimated transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur or when the uncertainty associated with the variable consideration is resolved. Our estimates of variable consideration and determination of whether to include estimated amounts in transaction price are based largely on an assessment of our anticipated performance and all information (historical, current and forecasted) that is reasonably available to us. The Company considers claims to be amounts in excess of approved contract prices that we seek to collect from our customers or others for customer-caused delays, errors in specifications and designs, contract terminations, change orders that are either in dispute or are unapproved as to both scope and price, or other causes of unanticipated additional contract costs. The effect of variable consideration on the transaction price of a performance obligation is recognized as an adjustment to revenue on a cumulative catch-up basis. To the extent unapproved change orders and claims reflected in transaction price (or excluded from transaction price in the case of liquidated damages) are not resolved in our favor, or to the extent incentives reflected in transaction price are not earned, there could be reductions in, or reversals of, previously recognized revenue.
The Company has projects where we are in the process of negotiating, or awaiting final approval of, unapproved change orders and claims with our customers. The Company is proceeding with its contractual rights to recoup additional costs incurred from its customers based on completing work associated with change orders, including change orders with pending change order pricing, or claims related to significant changes in scope which resulted in substantial delays and additional costs in completing the work. Unapproved change order and claim information has been provided to our customers and negotiations with the customers are ongoing. If additional progress with an acceptable resolution is not reached, legal action will be taken.  
Based upon ourthe Company’s review of the provisions of ourits contracts, specific costs incurred, and other related evidence supporting the unapproved change orders and claims, together in some cases as necessary with the views of the Company’s outside claim consultants, weCompany concluded that it was appropriate to include in project price amounts of $8.7 millionapproximately $15,700 and $10.0 million,$9,300 at June 30, 20182019 and December 31, 2017,2018, respectively, in project price. These amounts, reflected in “Costs and estimated earnings in excess of billings on uncompleted contracts” on our condensed consolidated balance sheets.
We expect these matters will be resolved withoutthe Condensed Consolidated Balance Sheets, primarily relate to extended delays on a material adverse effect on our financial statements.bridge project in Texas due to design errors in the original owner provided project plan. However, unapproved change order and claim amounts are subject to negotiations which may cause actual results to differ materially from estimated and recorded amounts.

Each of these contract types presents advantages and disadvantages. Typically, we assumethe Company assumes more risk with lump-sum contracts. However, these types of contracts offer additional profits when we complete the work is completed for less than originally estimated. Under fixed-unit price contracts, ourthe Company’s profit may vary if actual labor-hour costs vary significantly from the negotiated rates. Also, because some contracts can provide little or no fee for managing material costs, the components of contract cost can impact profitability.
Contract Balances
The timing of revenue recognition, billings and cash collections results in billed accounts receivable and costs and estimated earnings in excess of billings on uncompleted contracts (contract assets) on the condensed consolidated balance sheet.Condensed Consolidated Balance Sheet. In ourthe Company’s heavy civil construction segment, amounts are billed as work progresses in accordance with agreed-upon contractual terms, either at periodic intervals (e.g., biweekly or monthly) or upon achievement of contractual milestones. Generally, billing occurs subsequent to revenue recognition, resulting in contract assets. However, we sometimes receivethe Company occasionally receives advances or deposits from ourits customers, before revenue is recognized, resulting in billings in excess of costs and estimated earnings on uncompleted contracts (contract liabilities). These assets and liabilities are reported on the condensed consolidated balance sheetCondensed Consolidated Balance Sheet on a contract-by-contract basis at the end of each reporting period. Changes in the contract asset and liability balances during the six month period ended June 30, 2018,2019, were not materially impacted by any other factors.

4.Cash and Cash EquivalentsCONSOLIDATED 50% OWNED SUBSIDIARIES
The Company considers all highly liquid investments with original or remaining maturities of three months or less at the time of purchase to be cash equivalents. Cash and cash equivalents include cash balances held by our consolidated subsidiaries and our majority controlled construction joint ventures. At June 30, 2018 and December 31, 2017, cash and cash equivalents included $17.6 million and $31.1 million, respectively, belonging to our consolidated 50% owned subsidiaries. At June 30, 2018 and December 31, 2017, cash and cash equivalents included $12.3 million and $18.9 million, respectively, belonging to our construction joint ventures. Construction joint venture cash balances are limited to joint venture activities and are not available for other projects, general cash needs or distribution to us without approval of the board of directors, or equivalent body, of the respective joint ventures.
 Restricted cash of approximately $3.6 million is included in “Other current assets” on the condensed consolidated balance sheets as of June 30, 2018 and December 31, 2017 and represents $3.0 million of cash designated as collateral for a standby letter of credit and approximately $0.6 million represents cash deposited by a customer, for the benefit of the Company, in an escrow account which is restricted until the customer releases the restriction upon the completion of the job. 
 The Company holds cash on deposit in U.S. banks, at times, in excess of federally insured limits. Management does not believe that the risk associated with keeping cash deposits in excess of federal deposit insurance limits represents a material risk.

The Company may incur current state tax liabilities in states in which the Company does not have sufficient net operating loss carry forwards. IncomeCurrent income tax expense of $98 thousand$86 and $138 thousand$108 was recorded for the three and six months ended June 30, 2018, respectively. Income tax expense of $98 thousand2019, respectively and $125 thousand was recorded for the three and six months ended June 30, 2017,2018 was $97 and $138, respectively.
The Company’s deferred tax expense reflects the change in deferred tax assets and liabilities. The Company performs an analysis at the end of each reporting period to determine whether it is more likely than not the deferred tax assets are expected to be realized in future years. Based upon this analysis, a valuation allowance of approximately $31,700 has been applied to the Company’s net deferred tax assets at both June 30, 2019 and December 31, 2018. As part of this analysis, the Company monitors its quarterly results. Based on the Company’s continued positive income trend and current forecast for the full year of 2019, we believe that there could be enough positive evidence to remove the valuation allowance in the fourth quarter of 2019. Deferred tax liabilities are a consideration in the analysis of whether to apply a valuation allowance because taxable temporary differences may be used as a source of taxable income to support the realization of deferred tax assets. A deferred tax liability that relates to an asset with an indefinite life, such as goodwill, may not be considered a source of income and should not be netted against deferred tax assets for valuation allowance purposes. The Company expects to have a deferred tax liability for the excess of book over tax basis difference in its goodwill. A $620 and $761 deferred tax expense for the three and six months ended June 30, 2019, respectively has been recorded to reflect this liability.
The effective income tax rate varied from the statutory rate primarily as a result of the change in the valuation allowance, net income attributable to noncontrolling interest owners which is taxable to those owners rather than to the Company, state income taxes and other permanent differences. For interim periods, the Company estimates an annual effective tax rate and applies that rate to year-to-date operating results.
The Company’s deferred tax expense reflects the change in deferred tax assets or liabilities. The Company performs an analysis at the end of each reporting period to determine whether it is more likely than not the deferred tax assets are expected to be realized in future years. Based upon this analysis, a full valuation allowance has been applied to our net deferred tax assets as of June 30, 2018 and December 31, 2017. Therefore, there has been no change in net deferred taxes for the three and six months ended June 30, 2018.
As a result of the Company’s analysis, management has determined that the Company does not have any material uncertain tax positions.

Market Outlook and TrendsMARKET OUTLOOK AND TRENDS

Heavy Civil Construction
Our—Sterling’s heavy civil construction business is primarily driven by federal, state and municipal funding. The 2015 passageFederal funds, on average, provide 50% of annual State Department of Transportation (DOT) capital outlays for highway and bridge projects. Several of the states in Sterling’s key markets have instituted actions to further increase annual spending. In November 2018, various state and local transportation measures were passed securing, and in some cases increasing, funding of $1.57 billion in California, $1.27 billion in Texas, $528.5 million in Arizona, $128.2 million in Colorado and $87 million in Utah. In October 2018, the Federal Aviation Administration reauthorized $3.35 billion annually for the next five years. This reauthorization also includes more than $1 billion a year for airport infrastructure grants and about $1.7 billion for disaster relief.
In addition to the state locally funded actions, Sterling is in year four of the 2015 federally funded five-year $305 billion surface transportation bill will increaseFixing America’s Surface Transportation (“FAST”) Act that increased the annual federal highway investment by 15.1% over the five-year period from 2016 to 2020. In additionWith the FAST Act set to expire next year, the federal government is currently working towards a bipartisan Federal program, several ofInfrastructure Bill that would further stabilize the statesHighway Trust Fund. Should the federal government approve this incremental infrastructure investment in our key markets have instituted actions2019, it would be an additional growth catalyst; however, it would be unlikely to further increase annual spending. In Texas, two constitutional amendments were passed, which will increase the annual funds allocated to transportation projects from $4.0 billion to $4.5 billion per year. Texas also has locally approved bonds estimated at $1.3 billion that were approved in November 2017. In Utah, a 20% gas tax increase to support infrastructure projects was put into effect January 1, 2016, which is the first state gas tax increase in 18 years. The State of Utah also approved, in 2017, a $1 billion bond package for infrastructure improvements. A 12-cent sales tax increase was approved in Los Angeles, California in 2016 that will provide $3 billion per year for local road, bridge and transit projects. In addition, California approved a 10 year $52 billion bill that provides an annual $5 billion in incremental funding for use on highway transit repair projects, however a repeal referendum to remove the incremental funding will be up for vote in the fall of 2018. See “Item 1. Business—Our Markets, Competition and Customers” in our 2017 Form 10-K for a more detailed discussion of our markets and their funding sources.create significant business impact before 2020 or 2021.
Bid Discipline and Project Execution
To ensure that we takethe Company takes full advantage of the improved market conditions and maximizemaximizes profitability, we havethe Company has completed an extensive evaluation of ourits historical success on heavy civil construction projects’ historical successprojects based on project size, end customer, product delivered and geography. The knowledge gained has now been incorporated into a more formal and rigorous bid evaluation and approval process which, along with the institution of common processes, we believe will enable usthe Company to focus ourits resources on the most beneficial projects and significantly reduce ourits risk. In addition, in order to strengthen these processes and capitalize further on the improved market conditions, we appointed a Chief Operating Officer in the first quarter of 2016, and in the first quarter of 2018 we appointed a Vice President, Strategy and Business Development.
Backlog
At June 30, 2018, our Backlog2019, backlog of construction projects, which is made up solely of ourthe heavy civil construction segment, was $885$909.0 million, as compared to $745$850.7 million at December 31, 2017.2018. The contracts in this Backlogbacklog are typically completed in 12 to 36 months. Contracts for which we arethe Company is the apparent low bidder on the project (“Unsigned Low-bid Awards”) are excluded from Backlogbacklog until the contract has been executed by ourits customer. Unsigned Low-bid Awards were $156$314.9 million at June 30, 2019 as compared to $292.7 million at December 31, 2018. The combination of Backlogbacklog and Unsigned Low-bid Awards, which we referthe Company refers to as "Combined“Combined Backlog," totaled $1.04$1.2 billion and $995 million,$1.1 billion, respectively at June 30, 20182019 and December 31, 2017.2018. Backlog includes $28$34.3 million and $55$33.6 million at June 30, 20182019 and December 31, 2017,2018, respectively, attributable to ourthe Company’s share of estimated revenues related to joint ventures where we arethe Company is a noncontrolling joint venture partner.
OurThe Company’s margin in backlog has decreased approximately 20 basis points,increased from 8.4%8.5% at December 31, 2017 to 8.2% at June 30, 2018. The decrease noted above is primarily the result of change in project mix and proportionally lower backlog of our large projects in the Rocky Mountain region and Hawaii. Our margin in Combined Backlog increased2018 to 8.8% at June 30, 20182019 and the Combined Backlog margin increased from 8.3%8.9% at December 31, 2017.  2018 to 9.1% at June 30, 2019, driven by a greater mix of heavy highway awards.



Residential Construction

Heavy Civil Construction
Revenues
Heavy civil construction revenues were $223.3 million for the second quarter of 2018, an increase in our heavy civil construction segment of $14.1 million or 6.7% compared to the second quarter of 2017. The increase was primarily attributable to increased revenues of $30.1 million related to the commercial and aviation space, partially offset by the substantial completion of a large Rocky Mountain construction joint venture project and lower volume in Texas. Revenues increased $47.9 million or 13.2% in the six months ended June 30, 2018 compared with the six months ended June 30, 2017, primarily the result of six months2019 compared to three months contribution from the April 3, 2017 Tealstone Acquisition, which resulted in approximately $17.7$6.2 million in additional revenue.the second quarter of 2018. The remaining increase is driven by growth in our other civil work in the commercial and aviation space,interest expense on lower comparative debt levels was partially offset by higher interest rates. The interest expense is primarily related to borrowings under the substantial completion of a Hawaii project.

The improvement was the result of volume driven increases, offset by increased earnout expense2018 and start-up costs from the expansion into the Houston area. Operatingoperating income was $10.5$5.3 million for the six months ended June 30, 2018,2019, a decrease of $3.0 million, compared to the $8.3 million of income in the six months ended June 30, 2018. The decrease was the result of volume driven decreases from heavy highway work as well as negative weather impacts across our regions in the second quarter of 2019 and the six months ended June 30, 2019.


Residential Construction
Revenues—Revenues were $36.0 million for the second quarter of 2019, a decrease of $9.5 million or 20.9%, compared to the second quarter of 2018. The decrease in revenue was due to severe Texas weather conditions which delayed slab starts with approximately 30 unworkable days during the quarter.

Revenues were $78.7 million for the six months ended June 30, 2019, a decrease of $2.0 million or 2.5%, compared to the six months ended June 30, 2018. The decrease in revenue is due to the aforementioned second quarter weather impact, partially offset by completion of fourth quarter weather delayed slab starts that pushed into the first quarter of 2019 and underlying growth in the Dallas-Fort Worth and Houston areas in the first quarter of 2019. Completed slabs decreased approximately 1.8% in the six months ended June 30, 2019 as compared to the six months ended June 30, 2018.
Operating income—Operating income was $5.0 million for the second quarter of 2019, a decrease of $0.7 million, compared to the second quarter of 2018.

InflationINFLATION
Inflation generally has not had a material impact on ourthe Company’s financial results; however, from time to time, increases in oil, fuel and steel prices have affected ourits cost of operations. Anticipated cost increases and reductions are considered in ourthe Company’s bids to customers on proposed new construction projects.


When we arethe Company is the successful bidder on a heavy civil construction project, we executethe Company executes purchase orders with material suppliers and contracts with subcontractors covering the prices of most materials and services, other than oil and fuel products, thereby mitigating future price increases and supply disruptions. These purchase orders and contracts do not contain quantity guarantees and we havethe Company has no obligation for materials and services beyond those required to complete the contracts with ourits customers. There can be no assurance that increases in prices of oil and fuel used in ourthe Company’s business will be adequately covered by the estimated escalation we havethe Company has included in ourits bids and there can be no assurance that all of ourits vendors will fulfill their pricing and supply commitments under their purchase orders and contracts with the Company. We adjust ourThe Company adjusts the total estimated costs on our projects when we believeit is believed it is probable that wethere will havebe cost increases which will not be recovered from customers, vendors or re-engineering.
Inflation affects our residential construction projects minimally as these projects are typically completed in less than one month.
Off-Balance Sheet Arrangements and Joint VenturesOFF-BALANCE SHEET ARRANGEMENTS AND JOINT VENTURES
We participateThe Company participates in various construction joint ventures in order to share expertise, risk and resources for certain highly complex projects. The venture’s contract with the project owner typically requires joint and several liability among the joint venture partners. Although ourthe Company’s agreements with ourits joint venture partners provide that each party will assume and fund its share of any losses resulting from a project, if one of ourits partners is unable to pay its share, wethe Company would be fully liable for such share under ourits contract with the project owner. Circumstances that could lead to a loss under these guarantee arrangements include a partner’s inability to contribute additional funds to the venture in the event that the project incurs a loss or additional costs that wethe Company could incur should the partner fail to provide the services and resources toward project completion that had beento which it committed to in the joint venture agreement.
At June 30, 2018,2019, there was approximately $56$71.8 million of construction work to be completed on unconsolidated construction joint venture contracts, of which $28$34.3 million represented ourthe Company’s proportionate share. Due to the joint and several liability under ourthe Company’s joint venture arrangements, if one of ourits joint venture partners fails to perform, wethe Company and the remaining joint venture partners would be responsible for completion of the outstanding work. As of June 30, 2018, we are2019, the Company was not aware of any situation that would require usit to fulfill responsibilities of ourits joint venture partners pursuant to the joint and several liability provisions under ourits contracts.

CRITICAL ACCOUNTING ESTIMATES
The discussion and analysis of the financial condition and results of operations are based on the Company’s Condensed Consolidated Financial Statements, which have been prepared in accordance with U.S. GAAP. The preparation of these Condensed Consolidated Financial Statements requires the Company to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue and expenses and related disclosures of contingent assets and liabilities. The Company continually evaluates its estimates based on historical experience and various other assumptions that the Company believes to operating leasesbe reasonable under the circumstances. Actual results may differ from these estimates under different assumptions or conditions. The Company believes the following critical accounting policies involve more significant judgments and estimates used in the preparation of the Condensed Consolidated Financial Statements.

Revenue Recognition
Performance Obligations Satisfied Over Time—Revenue for the heavy civil construction segment contracts that satisfy the criteria for over time recognition is recognized as the work progresses. The Company measures transfer of control of the performance obligation utilizing the cost-to-cost measure of progress, with cost of revenue including direct costs, such as materials and labor, and indirect costs that are discussedattributable to contract activity. Under the cost-to-cost approach, the use of estimated costs to complete each performance obligation is a significant variable in “Item 7. Management’s Discussionthe process of determining recognized revenue and Analysisis a significant factor in the accounting for such performance obligations. Significant estimates that impact the cost to complete each performance obligation are: materials, components, equipment, labor and subcontracts; labor productivity; schedule durations, including subcontractor or supplier progress; contract disputes, including claims; achievement of Financial Conditioncontractual performance requirements; and Resultscontingency, among others.

Due to the various estimates inherent in our 2017 Form 10-K.contract accounting, actual results could differ from those estimates, which could result in material changes to the Company’s Condensed Consolidated Financial Statements and related disclosures.



Goodwill
At June 30, 2019, the Company’s goodwill balance was $85.2 million. Goodwill is not amortized to earnings, but instead is reviewed for impairment at least annually, absent any indicators of impairment or when other actions require an impairment assessment. The Company performs an annual impairment assessment during the fourth quarter of each year based on balances as of October 1. During the fourth quarter 2018, the Company performed a qualitative assessment of goodwill, and based on this assessment, no indicators of impairment were present. Additionally, during the six months ended June 30, 2019, the Company noted no indicators of impairment.

Other Intangible Assets
The Company amortizes finite-lived intangible assets on a straight-line basis with lives ranging from 5 to 25 years, absent any indicators of impairment. The Company reviews tangible assets and finite-lived intangible assets for impairment when events or changes in circumstances indicate that the carrying amount may not be recoverable. If a recoverability assessment is required, the estimated future cash flow associated with the asset or asset group will be compared to their respective carrying amounts to determine if an impairment exists. During the six months ended June 30, 2019, the Company noted no indicators of impairment. See Note 7 to the Financial Statements for further discussion of the Company’s other intangible assets.

Income Taxes
Deferred Tax Realization Assessments—The Company performs an analysis at the end of each reporting period to determine whether it is more likely than not the deferred tax assets are expected to be realized in future years. Based upon this analysis, a valuation allowance of approximately $31.7 million has been applied to the Company’s net deferred tax assets as of June 30, 2019. As part of this analysis, the Company monitors its quarterly results. Based on the Company’s continued positive income trend and current forecast for the full year of 2019, we believe that there could be enough positive evidence to remove the valuation allowance in the fourth quarter of 2019. Deferred tax liabilities are a consideration in the analysis of whether to apply a valuation allowance because taxable temporary differences may be used as a source of taxable income to support the realization of deferred tax assets. A deferred tax liability that relates to an asset with an indefinite life, such as goodwill, may not be considered a source of income and should not be netted against deferred tax assets for valuation allowance purposes. The Company expects to have a deferred tax liability for the excess of book over tax basis difference in its goodwill.

As a result of the Company’s analysis, management has determined that the Company does not have any material uncertain tax positions.

NEW ACCOUNTING STANDARDS
See the applicable section of Note 2 to the Condensed Consolidated Financial Statements for a discussion of new accounting standards.
Item 3. Quantitative and Qualitative Disclosures aboutAbout Market Risk
Changes in interest rates are one of ourthe Company’s sources of market risk. Interest on outstanding indebtedness under ourthe Oaktree Facility is equal to the one-, two-, three- or six-month London interbank rate,Interbank Offered Rate, or LIBOR, plus 8.75% per annum on the unpaid principal amount of the Loan, subject to adjustment under certain circumstances. The Company’s interest rates for the periods ended June 30, 2019, December 31, 2018 and June 30, 2018 were 11.14%, 11.18% and 10.87% respectively. This represents an increase of approximately 2.7 basis points year over year. There are no amortized principal payments; however, the Company is required to prepay the Loan, and in certain cases pay a prepayment premium thereon, with proceeds received from the issuances of debt or equity, transfers, events of loss and extraordinary receipts. The Company is required to make an offer quarterly to the lenders to prepay the Loan in an amount equal to 75% of its excess cash flow, plus accrued and unpaid interest thereon and a prepayment premium. At June 30, 2018, we2019, the Company had a term loan of $80.3$71.6 million outstanding under this facility. A 1% increase in ourthe interest rate would increase interest expense by $0.8$0.7 million per year.

Item 4. Controls and Procedures
Evaluation of Disclosure Controls and Procedures
Disclosure controls and procedures include, but are not limited to, controls and procedures designed to ensure that information required to be disclosed by an issuer in the reports that it files or submits under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), is accumulated and communicated to the issuer’s management, including the principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.
The Company’s principal executive officer and principal financial officer reviewed and evaluated the Company’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act). Based on that evaluation, the Company’s principal executive officer and principal financial officer concluded that the Company’s disclosure controls and procedures were effective at June 30, 20182019 to ensure that the information required to be disclosed by the Company in this Report is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms and is accumulated and communicated to the Company'sCompany’s management including the principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure.

Changes in Internal Control over Financial Reporting

Inherent Limitations on Effectiveness of Controls
Internal control over financial reporting may not prevent or detect all errors and all fraud. Also, projections of any evaluation of effectiveness of internal control to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
