The tools used by the chief operating decision maker ("CODM") to allocate resources and assess performance are based on two reportable and operating segments: marine, which operates under the Orion Marine Group brand and logo, and concrete, which operates under the TAS Commercial Concrete brand and logo.
Although we describethe Company describes the business in this report in terms of the services the Company provides, its base of customers and the areas in which it operates, the Company has determined that its operations currently comprise two reportable segments pursuant to Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 280, Segment Reporting.
In making this determination, the Company considered the similar economic characteristics of its operations that comprise its marine segment. For the marine segment, the methods used, and the internal processes employed, to deliver marine construction services are similar throughout the segment, including standardized estimating, project controls and project management. This segment has the same customers with similar funding drivers, and it complies with regulatory environments driven through Federal agencies such as the U.S. Army Corps of Engineers, U.S. Fish and Wildlife Service, U.S. Environmental Protection Agency and U.S. Occupational Safety and Health Administration ("OSHA"), among others. Additionally, the segment is driven by macro-economic considerations including the level of import/export seaborne transportation, development of energy-related infrastructure, cruise line expansion and operations, marine bridge infrastructure development, waterway pipeline crossings and the maintenance of waterways. These considerations, and others, are key catalysts for future prospects and are similar across the segment.

For the concrete segment, the Company also considered the similar economic characteristics of these operations. The methods used, and the internal processes employed, to deliver concrete construction services are similar throughout the segment, including standardized estimating, project controls and project management. This segment complies with regulatory environments such as OSHA. Additionally, this segment is driven by macro-economic considerations, including movements in population, commercial real estate development, institutional funding and expansion, and recreational development, specifically in metropolitan areas of Texas. These considerations, and others, are key catalysts for future prospects and are similar across the segment.
Basis of Presentation
The accompanying consolidated financial statements and financial information included herein have been prepared pursuant to the interim period reporting requirements of Form 10-Q.  Consequently, certain information and note disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States ("U.S. GAAP") have been condensed or omitted.  Readers of this report should also read ourthe Company's consolidated financial statements and the notes thereto included in ourits Annual Report on Form 10-K for the fiscal year ended December 31, 20172018 (“20172018 Form 10-K”) as well as Item 7 – Management’s Discussion and Analysis of Financial Condition and Results of Operations also included in our 2017its 2018 Form 10-K.
In the opinion of management, the accompanying unaudited consolidated financial statements contain all adjustments considered necessary for a fair presentation of the Company’s financial position, results of operations, and cash flows for the periods presented.  Such adjustments are of a normal recurring nature.  Interim results of operations for the six months ended June 30, 20182019 are not necessarily indicative of the results that may be expected for the year ending December 31, 2019.
Certain amounts in the prior year financial statements have been reclassified to conform to the current year presentation in the Company's condensed consolidated statement of operations. As part of the Company’s Invest, Scale and Grow initiative it realigned its project management personnel within the operating groups for the combined company. As a result of the realignment, beginning


in the second quarter of 2019, the Company has elected to classify certain project management costs in Cost of contract revenue in its Consolidated Statements of Operations (the “Statements of Operations”) to better represent how those costs are managed and controlled. For periods reported prior to the second quarter of 2019, certain project management costs were included in Selling, general and administrative (“SG&A”) expenses. The Company's SG&A expense for 2019 included project management costs of $1.1 million incurred in the first quarter of 2019, and SG&A expense for 2018. and 2017 included project management costs of $4.9 million and $4.7 million, respectively.





2.    Summary of Significant Accounting Principles

The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Management's estimates, judgments and assumptions are continually evaluated based on available information and experience; however, actual amounts could differ from those estimates. Please refer to Note 2 of the Notes to Consolidated Financial Statements included in our 2017the Company's 2018 Form 10-K for a discussion of other significant estimates and assumptions affecting ourits consolidated financial statements which are not discussed below.

On an ongoing basis, the Company evaluates the significant accounting policies used to prepare its consolidated financial statements, including, but not limited to, those related to:
    
Revenue recognition from construction contracts;
Accounts receivable and allowance for doubtful accounts;
GoodwillProperty, plant and other long-livedequipment;
Leases;
Finite and indefinite-lived intangible assets, testing for indicators of impairment;
Stock-based compensation;
Income taxes;
Self-insurance; and

Revenue Recognition

The Company adopted ASU 2014-09, Revenue from Contracts with Customers (Topic 606), on January 1, 2018, using the modified retrospective method. The Company recognized the cumulative effect of initially adopting Topic 606 guidance as an adjustment to the beginning balance of retained earnings. Contracts with customers that were not substantially complete in both the Company’s marine and concrete segments were evaluated in order to determine the impact as of the date of adoption. The comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods.

The Company’s revenue is derived from contracts to provide marine construction, dredging, turnkey concrete services, and other specialty services. The Company’s projects are typically short in duration and usually span a period of less than one year. The Company determines the appropriate accounting treatment for each contract before work begins and generally records revenue on contracts over time.

Performance obligations are promises in a contract to transfer distinct goods or services to the customer and are the unit of account under Topic 606. The Company's contracts and related change orders typically represent a single performance obligation because the Company provides a significant integrated service and individual goods and services are not separately identifiable and the Company provides a significant integrated service.identifiable. Revenue is recognized over time because control is continuously transferred to the customer. For contracts with multiple performance obligations, the Company allocates the contract's transaction price to each performance obligation using its best estimate of the stand-alone selling price of each distinct good or service. Progress is measured by the percentage of actual contract costs incurred to date to total estimated costs for each contract. This method is used because management considers contract costs incurred to be the best available measure of progress on these contracts. Contract costs include all direct costs, such as material and labor, and those indirect costs incurred that are related to contract performance such as payroll taxes and insurance. General and administrative costs are charged to expense as incurred. Upfront costs, incurredsuch as costs to mobilize personnel and equipment prior to satisfying a performance obligation are capitalized and amortized over the contract performance period.

Changes in job performance, job conditions and estimated profitability, including those arising from final contract settlements, may result in revisions to costs and reported revenue and are recognized in the period in which the revisions are determined. The


effect of changes in estimates of contract revenue or contract costs is recognized as an adjustment to recognized revenue on a cumulative catch-up basis. When losses on uncompleted contracts are anticipated, the entire loss is recognized in the period in which such losses are determined. Revenue is recorded net of any sales taxes collected and paid on behalf of the customer, if applicable.








Contract revenue is derived from the original contract price as modified by agreed-upon change orders and estimates of variable consideration related to incentive fees and change orders or claims for which price has not yet been agreed by the customer. The Company estimates variable consideration based on its assessment of the most likely amount to which it expects to be entitled. Variable consideration is included in the estimated transaction pricerecognition of revenue to the extent it is probable that a significant reversal of cumulative recognized revenue will not occur. As of June 30, 2018,2019, approximately $15.6$1.1 million of claims against customers has been recognized and is reflected on the Company's Consolidated Balance Sheet under "Costs and estimated earnings in excess of billings on uncompleted contracts." TheBased on its reading of the contract and its performance, the Company believes collection of these claims is probable, although the full amount of the recorded claims may not be collected.

Contract assets and liabilities include the following:

Accounts Receivable: Trade, net of allowance - Represent amounts billed and currently due from customers and are stated at their net estimated realizable value.
Accounts Receivable: Retainage - Represent amounts which have not been billed to customers or paid pursuant to retainage provisions in construction contracts, which generally become payable upon contract completion and acceptance by the customer.
Costs and Estimated Earnings in Excess of Billings on Uncompleted Contracts - Represent revenues recognized in excess of amounts billed, which management believes will be billed and collected within one year of the completion of the contract (i.e. Contract Assets) and are recorded as a current asset.asset, until such amounts are either received or written off.
Billings in Excess of Costs and Estimated Earnings on Uncompleted Contracts - Represent billings in excess of revenues recognized (i.e. Contract Liabilities) and are recorded as a current liability.liability, until the underlying obligation has been performed or discharged.

The Company’s evaluation of its construction contracts under the new standard focused on the following areas which have the most significant impact on the amount and timing of revenue recognized:

Performance Obligations - Construction contracts with customers, including those related to contract modifications, were reviewed to determine if there were any multiple performance obligations. Based on our review, a limited number of contracts in the marine segment and no contracts in the concrete segment were identified as having multiple performance obligations. The net impact on retained earnings as of January 1, 2018 and gross profit for the six months ended June 30, 2018 were not material.
Upfront Costs - These costs were required to be capitalized as assets and were recorded as part of "Costs and estimated earnings in excess of billings on uncompleted contracts" in the Company’s Consolidated Balance Sheets and amortized over the expected duration of the contract as part of "Costs of contract revenues" in the Company’s Consolidated Statements of Operations. If the expected completion date of the contract changes, the amortization period will be recalculated and adjusted prospectively. The amortization of such costs for the Company are generally comprised of initial costs incurred to mobilize equipment and labor to a job site or other upfront costs such as bonds or insurance prior to the "notice-to-proceed" date, which had been expensed as incurred in prior periods. Based on our review, certain contracts in the marine segment were identified as having material upfront costs. The Company also reviewed contracts for the concrete segment and while certain contracts within the segment were identified as having upfront costs, they were not considered material.

The following table summarizes the cumulative effect of the changes made to the Company’s unaudited Consolidated Balance Sheet as of January 1, 2018 from the adoption of Topic 606:

Remaining performance obligations represent the transaction price of firm orders or other written contractual commitments from customers for which work has not been performed, or is partially completed and excludes unexercised contract options and potential orders. As of June 30, 2018,2019, the aggregate amount of the remaining performance obligations was approximately $340.7$661.0 million. Of this amount, the Company expects to recognize $318.1$465.6 million, or 93%70%, in the next 12 months and the remaining balance thereafter.

Classification of Current Assets and Liabilities

The Company includes in current assets and liabilities amounts realizable and payable in the normal course of contract completion.

Cash and Cash Equivalents

The Company considers all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents.  At times, cash held by financial institutions may exceed federally insured limits.  The Company has not historically sustained losses on its cash balances in excess of federally insured limits.  Cash equivalents at June 30, 20182019 and December 31, 20172018 consisted primarily of overnight bank deposits.



Risk Concentrations

Financial instruments that potentially subject the Company to concentrations of credit risk principally consist of accounts receivable.

The Company depends on its ability to continue to obtain federal, state and local governmental contracts, and indirectly on the amount of funding available to these agencies for new and current governmental projects. Therefore, a portion of the Company’s operations is dependent upon the level and timing of government funding.  Statutory mechanics liens provide the Company high priority in the event of lien foreclosures following financial difficulties of private owners, thus minimizing credit risk with private customers.



Accounts Receivable

Accounts receivable are stated at the historical carrying value, less allowances for doubtful accounts. The Company has significant investments in billed and unbilled receivables as of June 30, 20182019 and December 31, 2017.2018. Billed receivables represent amounts billed upon the completion of small contracts and progress billings on large contracts in accordance with contract terms and milestone achievements. Unbilled receivables on contracts, which are included in costs in excess of billings, arise as revenues are recognized over time. Unbilled amounts on contracts represent recoverable costs and accrued profits not yet billed. Revenue associated with these billings is recorded net of any sales tax, if applicable. Past due balances over 90 days and other higher risk amounts are reviewed individually for collectability.  In establishing an allowance for doubtful accounts, the Company evaluates its contract receivables and costs in excess of billings and thoroughly reviews historical collection experience, the financial condition of its customers, billing disputes and other factors. The Company writes off potentially uncollectible accounts receivable against the allowance for doubtful accounts if it is determined that the amounts will not be collected or if a settlement is reached for an amount that is less than the carrying value. As of June 30, 20182019 and December 31, 2017,2018, the Company had nothas recorded an allowance for doubtful accounts.accounts of $4.3 million.
 
Balances billed to customers but not paid pursuant to retainage provisions in construction contracts generally become payable upon contract completion and acceptance by the owner.  Retainage at June 30, 20182019 totaled $37.9$36.9 million, of which $4.5$11.0 million is expected to be collected beyond June 30, 2019.2020. Retainage at December 31, 20172018 totaled $39.2$30.7 million.

The Company negotiates change orders and claims with its customers. Unsuccessful negotiations of claims could result in a change to contract revenue that is less than amounts recorded, which could result in the recording of a loss. Successful claims negotiations could result in the recovery of previously recorded losses. Significant losses on receivables could adversely affect the Company’s financial position, results of operations and overall liquidity.

Advertising Costs

The Company primarily obtains contracts through an open bid process, and therefore advertising costs are not a significant component of expense.  Advertising costs are expensed as incurred.  

Environmental Costs

Costs related to environmental remediation are charged to expense. Other environmental costs are also charged to expense unless they increase the value of the property and/or provide future economic benefits, in which event the costs are capitalized. Environmental liabilities, if any, are recognized when the expenditure is considered probable and the amount can be reasonably estimated. The Company did not recognize any environmental liabilities as of June 30, 2018 or2019 and December 31, 2017.2018.

Fair Value Measurements

The Company evaluates and presents certain amounts included in the accompanying consolidated financial statements at “fair value” in accordance with U.S. GAAP, which requires the Company to base its estimates on assumptions that market participants, in an orderly transaction, would use to price an asset or liability, and to establish a hierarchy that prioritizes the information used to determine fair value.  Refer to Note 98 for more information regarding fair value determination.

The Company generally applies fair value valuation techniques on a non-recurring basis associated with (1) valuing assets and liabilities acquired in connection with business combinations and other transactions; (2) valuing potential impairment loss related to long-lived assets; and (3) valuing potential impairment loss related to goodwill and indefinite-lived intangible assets.





Inventory

Current inventory consists of parts and small equipment held for use in the ordinary course of business and is valued at the lower of cost (using historical average cost) or net realizable value. Where shipping and handling costs are incurred by the Company, these charges are included in inventory and charged to cost of contract revenue upon use. Non-current inventory consists of spare parts (including engines, cutters and gears) that require special order or long-lead times for manufacture or fabrication, but must be kept on hand to reduce downtime. Refer to Note 87 for more information regarding inventory.

Property and Equipment



Property and equipment are recorded at cost. Ordinary maintenance and repairs that do not improve or extend the useful life of the asset are expensed as incurred.  Major renewals and betterments of equipment are capitalized and depreciated generally over three to seven years until the next scheduled maintenance.

When property and equipment are retired or otherwise disposed of, the cost and accumulated depreciation are removed from the accounts and any resulting gain or loss is included in results of operations for the respective period.  Depreciation is computed using the straight-line method over the estimated useful lives of the related assets for financial statement purposes, as follows:

Automobiles and trucks3 to 5 years
Buildings and improvements5 to 30 years
Construction equipment3 to 15 years
Vessels and other equipment1 to 15 years
Office equipment1 to 5 years

The Company generally uses accelerated depreciation methods for tax purposes where appropriate.

Dry-docking costs are capitalized and amortized using the straight-line method over a period ranging from three to 15 years. Dry-docking costs include, but are not limited to, the inspection, refurbishment and replacement of steel, engine components, tailshafts, mooring equipment and other parts of the vessel.  Amortization related to dry-docking activities is included as a component of depreciation.  These costs and the related amortization periods are periodically reviewed to determine if the estimates are accurate.  If warranted, a significant upgrade of equipment may result in a revision to the useful life of the asset, in which case the change is accounted for prospectively.

Property and equipment are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or asset group may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized in the amount by which the carrying amount of the asset exceeds the fair value of the asset. Assets to be disposed of are separately presented in the balance sheet and reported at the lower of the carrying amount or the fair value, less the costs to sell, and are no longer depreciated. There were no assets classified as held for sale as of June 30, 2018 or2019 and December 31, 2017.

Goodwill and Other Intangible Assets

Goodwill
The Company has acquired businesses and assets in purchase transactions that resulted in the recognition of goodwill.  Goodwill represents the costs in excess of fair values assigned to the identifiable assets acquired and liabilities assumed in the acquisition.  In accordance with U.S. GAAP, acquired goodwill is not amortized, but is subject to impairment testing at least annually at a reporting unit level (as of October 31 of each year) or more frequently if events or circumstances indicate the asset may be impaired. The Company determined its operations comprise two reporting units for goodwill impairment testing, which match its two operating segments for financial reporting. Tests of impairment require a two-step process to be performed to analyze whether or not goodwill has been impaired. The first step of this test used to identify potential impairment, compares the estimated fair value of a reporting unit with its carrying amount. The second step, if necessary, quantifies the impairment.






The Company assesses the fair value of its reporting units based on a weighted average of valuations based on market multiples, discounted cash flows and consideration of its market capitalization. The key assumptions used in the discounted cash flow valuations are discount rates, weighted average cost of capital and perpetual growth rates applied to cash flow projections. Also inherent in the discounted cash flow valuation models are past performance, projections and assumptions in current operating plans and revenue growth rates over the next five years. These assumptions contemplate business, market and overall economic conditions. Other considerations are assumptions that market participants may use in analysis of comparable companies. The underlying assumptions used for determining fair value, as discussed above, require significant judgment and are susceptible to change from period to period and could potentially cause a material impact to the income statement. In the future, the Company's estimated fair value could be negatively impacted by extended declines in its stock price, changes in macroeconomic indicators, sustained operating losses and other factors which may affect its assessment of fair value.
See Note 10 for additional discussion of goodwill and related goodwill impairment testing.2018.

Intangible Assets

Intangible assets that have finite lives are amortized.  In addition, the Company evaluates the remaining useful life of intangible assets in each reporting period to determine whether events and circumstances warrant a revision of the remaining period of amortization.  If the estimate of an intangible asset’s remaining life is changed, the remaining carrying value of such asset is amortized prospectively over that revised remaining useful life. Intangible assets that have indefinite lives are not amortized, but are subject to impairment testing at least annually or more frequently if events or circumstances indicate that the asset may be impaired.

The Company has one indefinite-lived intangible asset, a trade name, which is tested for impairment annually on October 31, or whenever events or circumstances indicate that the carrying amount of the trade name may not be recoverable. Impairment is calculated as the excess of the trade name's carrying value over its fair value. The fair value of the trade name is determined using the relief from royalty method, a variation of the income approach. This method assumes that if a company owns intellectual property, it does not have to "rent" the asset and is, therefore, "relieved" from paying a royalty. Once a supportable royalty rate is determined, the rate is then applied to the projected revenues over the expected remaining life of the intangible assetassets to estimate the royalty savings. This approach is dependent on a number of factors, including estimates of future growth and trends, royalty rates, discount rates and other variables.

See Note 10 9for additional discussion of intangible assets and trade name impairment testing.

Stock-Based Compensation

The Company recognizes compensation expense for equity awards over the vesting period based on the fair value of these awards at the date of grant. The computed fair value of these awards is recognized as a non-cash cost over the period the employee provides services, which is typically the vesting period of the award. The fair value of options granted is estimated on the date of grant using the Black-Scholes option-pricing model. The Black-Scholes option-pricing model requires the use of subjective assumptions in the computation. Changes in these assumptions can cause significant fluctuations in the fair value of the option award. The fair value


of restricted stock grants is equivalent to the fair value of the stock issued on the date of grant, and is measured as the closingmean price of the stock on the dateday of grant.

Compensation expense is recognized only for share-based payments expected to vest. The Company estimates forfeitures at the date of grant based on historical experience and future expectations. Thisexpectations and this assessment is updated on a periodic basis. See Note 1514 for further discussion of the Company’s stock-based compensation plan.

Income Taxes

The Company determines its consolidated income tax provision using the asset and liability method prescribed by U.S. GAAP,
which requires the recognition of income tax expense for the amount of taxes payable or refundable for the current period and for deferred tax liabilities and assets for the future tax consequences of events that have been recognized in an entity’s financial
statements or tax returns. The Company must make significant assumptions, judgments and estimates to determine its current
provision for income taxes, its deferred tax assets and liabilities, and any valuation allowance to be recorded against any deferred tax asset. The current provision for income tax is based upon the current tax laws and the Company’s interpretation of these laws, as well as the probable outcomes of any tax audits. The value of any net deferred tax asset depends upon estimates of the amount and category of future taxable income reduced by the amount of any tax benefits that the Company does not expect to realize. Actual operating results and the underlying amount and category of income in future years could render current assumptions, judgments and estimates of recoverable net deferred taxes inaccurate, thus impacting the Company’s financial position and results of operations. The Company computes deferred income taxes using the liability method. Under the liability method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Under the liability method, the effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period ofthat includes the enactment date.

The Company accounts for uncertain tax positions in accordance with the provisions of ASC 740-10 which prescribes a recognition threshold and measurement attribute for financial statement disclosure of tax positions taken, or expected to be taken, on its consolidated tax return.  The Company evaluates and records any uncertain tax positions based on the amount that management deems is more likely than not to be sustained upon examination and ultimate settlement with the tax authorities in the tax jurisdictions in which it operates.

See Note 13 for additional discussion of income taxes and the Tax Cuts and Jobs Act (the "Act"), which was enacted and signed into law on December 22, 2017.

Insurance Coverage

The Company maintains insurance coverage for its business and operations.  Insurance related to property, equipment, automobile, general liability, and a portion of workers' compensation is provided through traditional policies, subject to a deductible or deductibles.  A portion of the Company's workers’ compensation exposure is covered through a mutual association, which is subject to supplemental calls.
 
The marine segment maintains five levels of excess loss insurance coverage, totaling $200 million in excess of primary coverage. The marine segment's excess loss coverage responds to most of its policies when a primary limit of $1 million has been exhausted; provided that the primary limit for Contingent Maritime Employer’s Liability is $10 million and the Watercraft Pollution Policy primary limit is $5 million. The concrete segment maintains five levels of excess loss insurance coverage, totaling $200 million in excess of primary coverage. The concrete segment's excess loss coverage responds to most of its policies when a primary limit of $1 million has been exhausted.

If a claim arises and a potential insurance recovery is probable, the impending gain is recognized separately from the related loss. The recovery will only be recognized up to the amount of the loss once the recovery of the claim is deemed probable and any excess gain will fall under contingency accounting and will only be recognized once it is realized. The Company does not net insurance recoveries against the related claim liability as the amount of the claim liability is determined without consideration of the anticipated insurance recoveries from third parties.



Separately, the Company’s marine segment employee health care is provided through a trustpaid for by general assets of the Company and currently administered by a third party.  Funding of the trust is based on current claims. The administrator has purchased appropriate stop-loss coverage.  Losses on these policies up to the deductible amounts are accrued based upon known claims incurred and an estimate of claims incurred but not reported.  The accruals are derived from known facts, historical trends and industry averages to determine the best estimate of the ultimate expected loss. Actual claims may vary from estimates. Any adjustments to such reserves are included in the Consolidated Resultsconsolidated results of Operationsoperations in the period in which they become known. The Company's concrete segment employee health care is provided through two policies.  A fully-fundedfully funded policy is offered primarily to salaried employees and their dependents while a partially self-funded plan with an appropriate stop-loss is offered primarily to hourly employees and their dependents. The self-funded plan is funded to the maximum exposure and, as a result, is expected to receive a partial refund after the policy expiration.

The accrued liability for insurance includes incurred but not reported claims of $5.1$3.9 million and $5.2$5.7 million at June 30, 20182019 and December 31, 2017,2018, respectively.

Recent Accounting PronouncementsStandards Adopted in 2019
 
The FASB issues accounting standards and updates (each, an "ASU") from time to time to its ASC, which is the primary source of U.S. GAAP. The Company regularly monitors ASUs as they are issued and considers applicability to its business. All ASUs are adopted by their respective due dates and in the manner prescribed by the FASB. The following are those recently issued ASUs most likely to affect the presentation of the Company's condensed consolidated financial statements:

In February 2016, the FASBFinancial Accounting Standards Board ("FASB") issued an ASU 2016-02, Leases (Topic(Topic 842), which requires all lessees to recognize leaseright-of-use ("ROU") assets (i.e. right-to-use assets) on the balance sheet. These are assets that represents the lessee's right to use or control the use of specified assets for the lease terms and lease liabilities, which are lessee's obligations to makemeasured at the present value of the future minimum lease payments, at the lease commencement date. Lessor accounting remains largely unchanged under the new guidance. The standard also requires more detailed disclosures to enable users of financial statements to understand the nature, amount, timing, and uncertainty of cash flows arising from leases measuredleases. The Company adopted the new standard on January 1, 2019, on a discountedprospective basis, forgoing comparative reporting. The Company elected to utilize the transition guidance within the new standard, which allows the Company to carryforward the historical lease classification. The Company elected to not separate leases and non-lease components for all classes of underlying assets in which it is the lessee and made an accounting policy election to not account for leases with terms longer than 12 months. Leases with termsan initial term of 12 months or less will be accountedon the balance sheet. Adoption of the standard resulted in the recording of additional net ROU operating lease assets of approximately $23.3 million and lease liabilities for operating leases of approximately $24.0 million on the Consolidated Balance Sheets as of January 1, 2019. The adoption of this guidance did not have an impact on net income. See Note 17 for more information regarding leases.


similar to existing guidance for operating leases. Recognition, measurement and presentation of expenses will depend on classification as a finance or operating lease. Under the new standard, the Company will be required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. The guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those annual periods. The Company has developed a detailed plan to implement the new standard and, through a cross-functional steering committee, is assessing the impact of the new standard for all contractual arrangements that may qualify as leases. The Company expects the adoption of the new standard to have a material and equal increase to assets and liabilities on its consolidated balance sheets, primarily as a result of operating leases currently not recognized on its balance sheet.

In January 2017, the FASB issued ASU 2017-04, Simplifying the Test for Goodwill Impairment (Topic 350). The FASB issued this update to simplify how an entity is required to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit's goodwill with the carrying amount of that goodwill. The amendments in this update modify the concept of impairment from the condition that exists when the carrying amount of goodwill exceeds its implied fair value to the condition that exists when the carrying amount of a reporting unit exceeds its fair value. The guidance should be applied on a prospective basis and is effective for annual or interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted but the Company does not anticipate the new standard will materially impact the financial statements unless goodwill impairment is recognized in the future.

In January 2018, the FASB issued ASU 2018-01, Land Easement Practical Expedient for Transition to Topic 842. The FASB issued this update to provide an optional transition on practical expedient that, if elected, would not require companies to reconsider its accounting for existing or expired land easements before the adoption of Topic 842 and that were not previously accounted for as leases under Topic 840. The guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those annual periods. The Company is currently in the process of assessing the effects of adoption on its financial statements, but it does not anticipate the new standard will materially impact the financial statements.
During the periods presented in these financial statements, the Company implemented other new accounting pronouncements other than those noted above that are discussed in the notes where applicable.

3.    Revenue

Contract revenuesRevenues are recognized when control of the promised goods or services is transferred to the customer in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. The following table represents a disaggregation of the Company’s contract revenuesrevenue by service line for the marine and concrete segments:

Although the Company has disaggregated its contract revenues here in terms of services provided, it believes its operations comprise two reportable segments pursuant to FASB ASC Topic 280, Segment Reporting. In making this determination, the Company considered the similar characteristics of its operations as discussed in Note 1. Additionally, as discussed, both the marine and


concrete segments have limited contracts with multiple performance obligations.  The Company’s contracts often combine multiple services, such as engineering, dredging, diving and construction, into one distinct finished product which is transferred to the customer.  These contracts are often estimated and bid as one project and evaluated on performance as one project, not by individual services performed by each.  Both the marine and concrete segments have a single CODMchief operating decision maker (“CODM”) for the entire segment, not by service lines of the segments.  Resources are allocated by segment and financial and budgetary information is compiled and reviewed by segment, not service line. 

Marine Segment
Construction services include construction, restoration, maintenance, dredging and repair of marine transportation facilities, marine pipelines, bridges and causeways and marine environmental structures. Dredging services generally enhance or preserve the navigability of waterways or the protection of shorelines through the removal or replenishment of soil, sand or rock. Specialty services include design, salvage, demolition, surveying, towing, diving and underwater inspection, excavation and repair.

Concrete Segment
Structural services include elevated concrete pouring for products such as columns, elevated beams and structural walls. Light commercial services include horizontally poured concrete for products such as sidewalks, ramps, tilt walls and trenches. Other services comprise labor related to concrete pouring such as rebar installation and pumping services and typically support the segment'sCompany's structural and light commercial services.


4.    Business Acquisition

On April 9, 2017, TAS Commercial Concrete Construction, LLC ("TAS"), a wholly owned subsidiary of the Company entered into a Stock Purchase Agreement (the "Agreement") for the purchase of all the issued and outstanding shares (the "shares") of Tony Bagliore Concrete, Inc., a Texas corporation ("TBC"). The Company and the two sole shareholders of TBC closed the purchase transactions on April 10, 2017 (the "Closing Date"). Upon the terms of and subject to the conditions set forth in the Agreement, the total aggregate consideration paid on the Closing Date by the Company to the sellers for the shares was $6.0 million in cash. In addition however, if certain target considerations are met in future periods, an additional cash payment of up to $2.0 million will become payable to the sellers.

The purpose of the acquisition was primarily to achieve growth by expanding the Company's current service offerings in addition to expansion into new markets. The tangible assets acquired include accounts receivable, retainage and fixed assets.

Under the acquisition method of accounting, the total acquisition consideration is allocated to the acquired tangible and intangible assets and assumed liabilities of TBC based on their estimated fair values as of the closing of the acquisition. The table below outlines the total actual acquisition consideration allocated to the fair values of TBC’s tangible and intangible assets and liabilities as of April 9, 2017 and subsequent adjustments:


Accounts receivable$3,239
Retainage1,860
Fixed assets, net2,098

Goodwill2,562
Other intangible assets878
Accounts payable(2,017)
Accrued expenses and other current liabilities(1,080)
Contingent consideration(456)
Deferred tax liability(1,093)
Total Acquisition Consideration at April 9, 2017$6,000
Working capital adjustment (all attributable to Goodwill)557
Total Acquisition Consideration$6,557
The excess of the acquisition consideration over the fair value of assets acquired and liabilities assumed was allocated to goodwill. The goodwill of $3.1 million arising from the acquisition consists primarily of synergies and business opportunities expected to be realized from the purchase of the business. The goodwill is not deductible for income tax purposes.

Finite-lived intangible assets include customer relationships and contractual backlog. (See Note 10).
The fixed assets acquired include construction equipment and automobiles and trucks and will be depreciated in accordance with Company policy, generally 3 to 15 years.
As stated in the Agreement, the Company has agreed to pay the sellers up to $2.0 million in cash, if earned, as additional purchase consideration. The seller's right to receive the contingent consideration, if any, shall be based on the Company's achievement of certain future financial targets. The Company measured the fair value of the contingent consideration at the April 9, 2017 acquisition date, and determined the fair value to be approximately $0.5 million, as shown above. This amount of contingent liability is classified on the Consolidated Balance Sheets as other long-term liabilities.
Pro Forma Results (unaudited)
The results and operations of TBC have been included in the Consolidated Statements of Operations since the acquisition date of April 9, 2017. The Company has calculated the pro forma impact of the acquisition of TBC on its operating results for the six months ended June 30, 2017:

 For the Six Months Ended
 June 30, 2017
Contract revenues$281,684
Operating loss from operations$(4,510)
Net loss$(4,464)
Basic loss per share$(0.16)
Diluted loss per share$(0.16)
The Company derived the pro forma results of the acquisition based upon historical financial information obtained from the seller and certain management assumptions. The pro forma adjustments related to incremental amortization expense associated with the acquired finite-lived intangible assets and interest expense associated with borrowings to effect the transaction, assuming a January 1, 2017 effective transaction date. In addition, the tax impact of these adjustments was calculated at a 35% statutory rate.

These pro forma results are not necessarily indicative of the results that would have been obtained had the acquisition of TBC been completed on January 1 of the respective period, or that may be obtained in the future.







5.    Concentration of Risk and Enterprise-Wide Disclosures

Accounts receivable include amounts billed to governmental agencies and private customers and do not bear interest. Balances billed to customers but not paid pursuant to retainage provisions generally become payable upon contract completion and acceptance by the owner.

The table below presents the concentrations of current receivables (trade and retainage) at June 30, 20182019 and December 31, 2017,2018, respectively:

In the three months ended June 30, 2019, one customer in the local governments category accounted for 14% of total contract revenues. In the three months ended June 30, 2018, a private customer generatedaccounted for 16% of total contract revenues. In the threesix months ended June 30, 2017, no single2019, one customer in the local governments category accounted for more than 10%11% of total contract revenues. In the six months ended June 30, 2018, a private customer generatedaccounted for 12% of total contract revenues. In the six months ended, June 30, 2017, no single customer accounted for more than 10% of total contract revenues.



The Company does not believe that the loss of any one of its customers would have a material adverse effect on the Company or its subsidiaries and affiliates since no single specific customer sustains such a large portion of receivables or contract revenue over time.

In addition, the concrete segment primarily purchases concrete from select suppliers. The loss of any one of these suppliers could adversely impact short-term operations.

8.7.    Inventory

Current inventory at June 30, 20182019 and December 31, 2017,2018, of $3.9$0.9 million and $4.4$1.1 million, respectively, consisted primarily of spare parts and small equipment held for use in the ordinary course of business.

Non-current inventory at June 30, 20182019 and December 31, 20172018 of $4.8$7.5 million and $4.9$7.6 million, respectively, consisted primarily of spare engine components or items which require longer lead times for sourcing or fabrication for certain of the Company's assets to reduce equipment downtime.

9.8.    Fair Value

Recurring Fair Value Measurements

The fair value of financial instruments is the amount at which the instrument could be exchanged in a current transaction between willing parties.  Due to their short-term nature, the Company believes that the carrying value of its accounts receivable, other current assets, accounts payable and other current liabilities approximate their fair values.

The Company classifies financial assets and liabilities into the following three levels based on the inputs used to measure fair value in the order of priority indicated:

Level 1- fair values are based on observable inputs such as quoted prices in active markets for identical assets or liabilities;
Level 2 - fair values are based on pricing inputs other than quoted prices in active markets for identical assets and liabilities and are either directly or indirectly observable as of the measurement date; and
Level 3- fair values are based on unobservable inputs in which little or no market data exists.

Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The Company's assessment of the significance of a particular input to the fair value requires judgment and may affect the placement of assets and liabilities within the fair value hierarchy levels.

The following table sets forth by level within the fair value hierarchy the Company's recurring financial assets and liabilities that were accounted for at fair value on a recurring basis as of June 30, 20182019 and December 31, 2017:2018:

The Company's derivatives, which are comprised of interest rate swaps, are valued using a discounted cash flow analysis that incorporates observable market parameters, such as interest rate yield curves and credit risk adjustments that are necessary to reflect the probability of default by usit or the counterparty. These derivatives are classified as a Level 2 measurement within the fair value hierarchy. See Note 1211 for additional information on the Company's derivative instrument.

OurThe Company's concrete segment has life insurance policies covering employees with a combined face value of $11.1 million as of June 30, 2018.million. The policies are invested in mutual funds and the fair value measurement of the cash surrender balance associated with these policies is determined using Level 2 inputs within the fair value hierarchy and will vary with investment performance. These assets are included in the "Other non-current" asset section in the Consolidated Balance Sheets.




Non-Recurring Fair Value Measurements

The Company generally applies fair value valuation techniques on a non-recurring basis associated with (1) valuing assets and liabilities acquired in connection with business combinations and other transactions; (2) valuing potential impairment loss related to long-lived assets; and (3) valuing potential impairment loss related to goodwill andthe indefinite-lived intangible assets.asset.

Other Fair Value Measurements

The fair value of the Company's debt at June 30, 20182019 and December 31, 20172018 approximated its carrying value of $90.0$83.0 million and $88.8$80.5 million, respectively, as interest is based on current market interest rates for debt with similar risk and maturity. If the Company's debt was measured at fair value, it would have been classified as a Level 2 measurement in the fair value hierarchy.

10.9.    Goodwill and Intangible Assets

Goodwill

At June 30,In the fourth quarter of 2018, the Company's annual goodwill totaledimpairment test indicated that its goodwill was fully impaired, primarily due to a decline in the Company's market capitalization and as a result it incurred a goodwill impairment charge of $69.5 million of whichwith $33.8 million relatesrelated to the marineMarine segment and $35.7 million relatesrelated to the concreteConcrete segment.

As discussed previously in Note 2, goodwill is reviewed at a reporting unit level for impairment annually as of October 31 or whenever circumstances arise that indicate a possible impairment might exist. Test of impairment requires a two-step process to be performed to analyze whether or not goodwill has been impaired. The first step of this test used to identify potential impairment, compares the estimated fair value of a reporting unit with its carrying amount. The second step, if necessary, quantifies the impairment. No indicators of goodwill impairment were identified during the six months ended June 30, 2018.

DerivativeDerivative Financial Instruments

On September 16, 2015, the Company entered into a series of receive-variable, pay-fixed interest rate swaps to hedge the variability in the interest payments on 50% of the aggregate principal amount of the Regions Term Loan outstanding, beginning with a notional amount of $67.5 million. There are a total of five sequential interest rate swaps to achieve the hedged position and each year on August 31, with the exception of the final swap, the existing interest rate swap is scheduled to expire and will be immediately replaced with a new interest rate swap until the expiration of the final swap on July 31, 2020.2023. On December 6, 2018, the Company entered into a sixth receive-variable, pay-fixed interest rate swaps to hedge the variability of interest payments. The sixth swap will begin with a notional amount of $27.0 million on July 31, 2020 will hedge the variability in the interest payments on 50% of the aggregate scheduled principal amount of the Regions Term Loan outstanding. The sixth swap is scheduled to expire on July 31, 2023. At inception, these interest rate swaps were designated as a cash flow hedge for hedge accounting, and as such, the effective portion of unrealized changes in market value are recorded in accumulated other comprehensive (loss) income (loss) and reclassified into earnings during the period in which the hedged forecasted transaction affects earnings. Gains and losses from hedge ineffectiveness are recognized in current earnings. The change in fair market value of the swaps for the six months endedas of June 30, 2018 was $0.32019 is approximately $1.1 million, net of tax.which is reflected in the balance sheet as a liability in Other non-current liabilities on the Consolidated Balance Sheets. The fair market value of the swaps as of June 30, 2018 was $0.4 million and net of tax was $0.3 million, which2019 is reflected as an asset in "Other non-current assets" on the Consolidated Balance Sheets.$(1.1) million. See Note 98 for more information regarding the fair value of the Company's derivative instruments.

13.12.    Income Taxes

The Company's effective tax rate is based on expected income, statutory rates and tax planning opportunities available to it. For interim financial reporting, the Company estimates its annual tax rate based on projected taxable (loss) income (or loss) for the full year and records a quarterly tax provision in accordance with the anticipated annual rate. Income tax expense included in the Company’s accompanying Consolidated Statements of Operations werewas as follows (in thousands, except percentages):


Three months ended June 30,Six months ended June 30,Three months ended June 30, Six months ended June 30,

Effective tax rate42.5%41.5%33.1%39.2%7.9%42.5% (5.0)%33.1%

The effective rate for the three and six months ended June 30, 20182019 differed from the Company's statutory federal rate of 21.0% driven by21% primarily due to to the recording of an additional valuation allowance to offset net operating loss carryforwards generated during the period, foreign income taxes, state income taxes and the non-deductibility of certain permanent items, such as incentive stock compensation expense, and increase in the valuation allowance primarily related to state attributes. Partially offsetting the impact of these items for the six months ended June 30, 2018, the Company recorded a $5.4 million gain related to the settlement of a legal matter. The gain was treated as a discrete item and and tax effected at a rate of 23.0% which was significantly lower than the rate applied to income generated through normal business operations.items.

The effective tax rate forDuring the three and six monthsyear ended June 30, 2017 differed fromDecember 31, 2018 the Company’s statutory federal rate of 35.0% primarily due to state income taxes, the non-deductibility of certain permanent items, such as incentive stock compensation expense, a movement in the valuation allowance related to state attributes and a benefit related to the domestic production gross receipts deduction.

The Company assessed the realizability of its deferred tax assets at June 30, 2018, and considered whetherdetermined that it was more likely than not that some portion or all of the deferred tax assets willwould not be realized. The realization ofrealized and therefore recorded a valuation allowance on the net deferred tax assets depends uponassets. The Company assesses the generation ofavailable positive and negative evidence to estimate if sufficient future taxable income which includeswill be generated to use the existing deferred tax assets. The Company considers the scheduled reversal of deferred tax liabilities, relatedavailable carryback periods, and tax-planning strategies in making this assessment. For the period ended June 30, 2019 the Company evaluated all positive and negative evidence in determining the amount of deferred tax assets more likely than not to depreciation, duringbe realized. Based on the periods in which these temporary differences become deductible.review of available evidence, Management believes that a valuation allowance on the net deferred tax assets at June 30, 2019 remains appropriate.

The Company does not expect that unrecognized tax benefits as of June 30, 20182019 for certain federal income tax matters will significantly change due to any settlement and/or expiration of statutes of limitations over the next 12 months. The final outcome of these uncertain tax positions is not yet determinable. The Company's uncertain tax benefits, if recognized, would affect itsthe Company's effective tax rate.

Enactment of Tax Reform

The Act made broad and complex changes to the U.S. tax code that significantly affected the Company's income tax rate. The Act, among other things, reduced the U.S. federal corporate income tax rate from 35% to 21%; limited the use of foreign tax credits to reduce U.S. income tax liability; repealed the corporate alternative minimum tax ("AMT") and changed how existing AMT credits can be realized; allowed immediate expensing for qualified assets; created a new limitation on deductible interest expense; repealed the domestic production activities deduction; and limited the deductibility of certain executive compensation and other deductions.

In accordance with Staff Accounting Bulletin 118 (“SAB 118”), the Company recognized provisional tax impacts related to the re-measurement of its net deferred tax liabilities and the addition of a partial valuation allowance recorded against existing foreign tax credit carryforwards not expected to be utilized in future tax years during the year ended December 31, 2017. As of June 30, 2018, the Company has not made any measurement-period adjustments that materially impacted its 2018 effective tax rate. Such adjustments may be necessary in future periods due to additional guidance that may be issued, changes in assumptions made and the finalization of U.S. income tax positions with the filing of the Company's 2017 U.S. income tax return which will allow for the ability to conclude whether any further adjustments are necessary to its deferred tax assets and liabilities. Any adjustments to these provisional amounts will be reported as a component of income tax expense (benefit) in the reporting period in which any such adjustments are identified but no later than the fourth quarter of 2018. The Company will continue to analyze the Act in order to finalize any related impacts within the measurement period.

14.13.     (Loss) Earnings (Loss) Per Share

Basic (loss) earnings (loss) per share areis based on the weighted average number of common shares outstanding during each period. Diluted (loss) earnings per share areis based on the weighted average number of common shares outstanding andas well as the effect of all dilutive common stock equivalents during each period.period net income is generated. The exercise price for certain stock options awarded by the Company exceeds the average market price of the Company's common stock. Such stock options are antidilutive and are not included in the computation of (loss) earnings per share. For the three monthsmonth periods ended June 30, 20182019 and June 30, 2017,2018, the Company had 2,012,4811,651,916 and 2,251,0342,012,481 securities, respectively, that were potentially dilutive in future earnings per share


calculations. For the six months ended June 30, 20182019 and June 30, 2017,2018, the Company had 1,969,6231,699,936 and 2,243,7631,969,623 securities, respectively, that were potentially dilutive in future earnings per share calculations. Such dilution will be dependent on the excess of the market price of the Company's stock over the exercise price and other components of the treasury stock method.



The exercise price for certain stock options awarded by the Company exceeds the average market price of the Company's common stock. Such stock options are antidilutive and are not included in the computation of earnings (loss) per share.

Grant-date fair value$2.78
Risk-free interest rate2.65%
Expected volatility51.8%

16.15.    Commitments and Contingencies

FromThe Company and one former and two current officers are named defendants in a class action lawsuit filed on April 11, 2019 in the United States District Court for the Southern District of Texas, Houston Division, seeking unstated compensatory damages under the federal securities laws allegedly arising from materially false and misleading statements during the period of March 13, 2018 to March 18, 2019. The complaint asserts, among other things, that the current and former officers caused the Company to overstate goodwill in certain periods; overstate accounts receivable; that the company lacked effective internal controls over financial reporting related to goodwill impairment testing and accounts receivable; and that as a result the required adjustments to goodwill and accounts receivable materially impacted the company’s financial statements causing the company’s stock price to be artificially inflated during the class period.  The Company will respond to the complaint, considers all of these allegations without merit and will vigorously contest the allegations. 

In addition, from time to time, the Company is a party to various lawsuits, claims and other legal proceedings that arise in the ordinary course of business. These actions typically seek, among other things, compensation for alleged personal injury, breach of contract, property damage, punitive damages, civil penalties or other losses, or injunctive or declaratory relief. With respect to such lawsuits, the Company accrues reserves when it is probable a liability has been incurred and the amount of loss can be reasonably estimated. The Company does not believe any of these or any other proceedings, individually or in the aggregate, would be expected to have a material adverse effect on results of operations, cash flows, or financial condition.condition

A pending legal matter was settled for $5.5 million and $0.5 million, respectively, during the first quarter of 2018.  Settlement amounts were recorded in "OtherOther gain from continuing operations"operations in the Consolidated Statement of Operations, "PrepaidPrepaid expenses and other"other (current portion of the notes receivable) and "OtherOther non-current assets"assets (non-current portion of the notes receivable) in the Consolidated Balance Sheets.  As of June 30, 2018,2019, the current portion of the notenotes receivable was $0.8 million and the non-current portion was $4.0 million.$2.8 million, net of $0.4 million of unamortized discount.  Legal fees related to this matter were expensed as incurred during the respective reporting period. 

As a result of charges brought in September 2015 and October 2016 by the Houston Police Department, Environmental Enforcement, two subsidiaries of the Company were indicted at the request of the Harris County, Texas District Attorney’s Office by a duly organized Grand Jury of Harris County, Texas for separate but similar violations of the Texas Water Code, allegedly arising from the handling of construction concrete at certain work sites. Specifically, in each case the Company was charged with unlawfully, intentionally or knowingly discharging a waste or pollutant and is subject to a maximum fine of $250,000. In addition, a project supervisor was also indicted in the second case. However, without admitting to fault, the Company has, in the first case, recently agreed to a diversion agreement that will result in the dismissal of all charges without prosecution upon completion of the agreement terms and payment of $15,000. More recently, the Company and its project supervisor have been offered diversion agreements in the second case that would result in dismissal of all charges against each of them upon completion of the terms of the agreements and payment by the Company of $100,000. None of these allegations nor the costs of defense, taken separately or as a whole, is expected to have a material impact on the Company’s balance sheet or its liquidity. The Company considers the first case settled and the second case without merit and thus has vigorously defend itself and its employee.

The Company entered into a lease arrangement with an entity in which an employee owns an interest. This lease ishas operating and finance leases for office space, equipment and yard facilities used byvehicles.

Management determines if a contract is or contains a lease at inception of the concrete segment. Annualcontract or modification of the contract. A contract is or contains a lease if the contract conveys the right to control the use of an identified asset for a period in exchange for consideration. Control over the use of the identified asset means the lessee has both (a) the right to obtain substantially all of the economic benefits from the use of the asset and (b) the right to direct the use of the asset.

Finance and operating lease ROU assets and liabilities are recognized based on the present value of future minimum lease payments over the expected lease term at a commencement date. As the implicit rate is not determinable in most of the Company's leases, management uses the Company's incremental borrowing rate based on the information available at commencement date in determining the present value of future payments. The expected lease term includes options to extend or terminate the lease when it is reasonably certain the Company will exercise such option. Lease expense for minimum lease payments is recognized on a straight-line basis over the expected lease term.

The Company's lease arrangements have lease and non-lease components. Leases with an expected term of 12 months or less are not accounted for on the balance sheet and the related lease expense was approximately $0.8is recognized on a straight-line basis over the expected lease term.

19.    Subsequent Events

Subsequent to the end of the second quarter 2018, the Company initiated discussions with the lead bank regarding a Fourth Amendment to the Credit Agreement. The Fourth Amendment, which provides the Company with greater flexibility while reducing overall cost, was executed and effective as of July 31, 2018. The provisions of the Fourth Amendment will extend the maturity date of the Credit Facility to July 31, 2023 and will reduce the number of syndicate partners by one bank. The Fourth Amendment will also include changes to the amortization schedule of required payments on the term loan and will change the total commitment amounts of the Credit Facility to $60.0 million for the term loan and $100.0 million for the revolving line of credit and swingline loans. With the execution of the Fourth Amendment, the existing Credit Facility will be treated as an extinguishment of debt and accounted for under the guidelines of ASC 470-05, Debt, Modifications and Extinguishments, and all unamortized debt issuance costs of approximately $2.1 million will be recognized as interest expense as of July 31, 2018. The new debt issuance costs of approximately $0.9 million related to the execution of the Fourth Amendment will be amortized through the new maturity date.

Overview

Orion Group Holdings, Inc., its subsidiaries and affiliates (hereafter collectively referred to as the "Company"), provides a broad range of specialty construction services in the infrastructure, industrial and building sectors of the continental United States, Alaska, Canada and the Caribbean Basin. The Company’s marine segment services the infrastructure sector through marine transportation facility construction, marine pipeline construction, marine environmental structures, dredging of waterways, channels and ports, environmental dredging, design, and specialty services.  Its concrete segment services the building sector by providing turnkey concrete construction services including pour and finish, dirt work, layout, forming, rebar, and mesh across the light commercial structural and other associated business areas. The Company is headquartered in Houston, Texas with offices throughout its operating areas.

Our contracts are obtained primarily through competitive bidding in response to “requests for proposals” by federal, state and local agencies and through negotiation and competitive bidding with private parties and general contractors. Our bidding activity and strategies are affected by such factors as our backlog, current utilization of equipment and other resources, job location, our ability to obtain necessary surety bonds and competitive considerations. The timing and location of awarded contracts may result in unpredictable fluctuations in the results of our operations.




Most of our revenue is derived from fixed-price contracts. We generally record revenue on construction contracts over time, measured by the percentage of actual contract costs incurred to date to total estimated costs for each contract. There are a number of factors that can create variability in contract performance and therefore impact the results of our operations. The most significant of these include the following:

completeness and accuracy of the original bid;
increases in commodity prices such as concrete, steel and fuel;
customer delays, work stoppages, and other costs due to weather and environmental restrictions;
availability and skill level of workers; and
a change in availability and proximity of equipment and materials.

All of these factors can have a negative impact on our contract performance, which can adversely affect the timing of revenue recognition and ultimate contract profitability. We plan our operations and bidding activity with these factors in mind and they generally have not had a material adverse impact on the results of our operations in the past.

Second quarter 20182019 recap and 20182019 Outlook

During the second quarter, the Company had solidgrew backlog to historical highs with a record win rate on bid markets opportunities. Results have improved quarter over quarter due to the strong backlog and execution with strong market drivers, particularly inon a number of projects within the marine segment. quarter.
The Company continues to focus on developing opportunities across the infrastructure, industrial, and building sectors through organic growth, greenfield expansion, and strategic acquisition opportunities.opportunities. The Company is also making headway on the Invest, Sale, Grow Initiative as the year progresses. Overall, the Company remains pleased with the endcontinues to see robust market drivers across its business and continues to expect 2018 will see improvements over 2017.improved results as 2019 progresses.

Marine Segment

Demand for our marine construction services remains strong. We continue to see solid demand to help maintain and expand the
infrastructure that facilitates the movement of goods and people on or over waterways. Specifically, we continue to see bid opportunities from our private sector energy-related customers as they expand their marine facilities related to the storage, transportation and refining of domestically produced energy. Over the long-term, we expect to see some bid opportunities in this sector from petrochemical-related customers, energy exporters, and liquefied natural gas facilities. Opportunities from local port authorities also remain solid, many of which are related to the completion of the Panama Canal expansion project. Additionally, we expect to see some bid opportunities related to coastal restoration funded through the Resource and Ecosystems Sustainability, Tourist Opportunities and Revived Economies of the Gulf Coast States Act (the "RESTORE Act") and new U.S. Army Corps of Engineers ("USACE") disaster recovery projects in Texas throughout 2018.2019. We believe our current equipment fleet will allow us to better meet market demand for projects from both our public and private customers in the future.

In the long-term, we see positive trends in demands for our services in our end markets, including:
General demand to repair and improve degrading U.S.U. S. marine infrastructure;
Improving economic conditions and increased activity in the petrochemical industry and energy-related companies will necessitate capital expenditures, including larger projects, as well as maintenance call-out work;


Expected increases in cargo volume and future demands from larger ships transiting the Panama Canal that will require ports along the Gulf Coast and Atlantic Seaboard to expand port infrastructure as well as perform additional dredging services;
The Water Resources Reform and Development Act (the "WRRDA Act") authorizing expenditures for the conservation and development of the nation's waterways as well as addressing funding deficiencies within the Harbor Maintenance Trust Fund;
Renewed focus on coastal rehabilitation along the Gulf Coast, particularly through the use of RESTORE Act funds based on fines collected related to the 2010 Gulf of Mexico oil spill;
Funding for highways and transportation under the FAST Act, which provides authority through 2020; and
Nearly $5 billion of federal funding provided by the USACE in connection with disaster recovery in Texas

Concrete Segment

Our concrete segment's demand also remains strong. The Texas building sector is in solid shape as its four major metropolitan areas, and expanding suburbs, continuously retain their positions as leading destinations for families and businesses to reside.businesses. Population growth throughout our markets continues to drive new distribution centers, education facilities, office expansion, retail and grocery establishments and new multi-family housing units. In Houston, warehouse construction and new education facilities continue to comprise a large portion of project mix. The Dallas-Fort Worth office continues its efforts to expand the services it offers beyond light commercialsee opportunities from warehouse distribution centers and will beis targeting structural construction opportunities going forward. As anticipated, ouropportunities. In the Central Texas operationsoffice, retail facilities and warehouse construction are performing well asdriving the project mix. Long-term, we are seeing solid project execution and expanding market share along the I-35


corridor. Sustainedsee sustained demand for concrete services in Houston, Dallas/Fort Worth, Austin, and San Antonio markets, coupled with continued progress being made in Central Texas, indicate the concrete segment should continue providing meaningful contribution to EBITDA throughout 2018.our markets.

Consolidated Results of Operations

Backlog Information

Our contract backlog represents our estimate of the revenues we expect to realize under the portion of contracts remaining to be performed. Given the typical duration of our contracts, which is generally less than onea year, our backlog at any point in time usually represents only a portion of the revenue that we expect to realize during a twelve-monthtwelve month period. Many projects that make up our backlog may be canceled at any time without penalty; however, we can generally recover actual committed costs and profit on work performed up to the date of cancellation. Although we have not been adversely affected by contract cancellations or modifications in the past, we may be in the future, especially in economically uncertain periods. Consequently, backlog is not necessarily indicative of future results. In addition to our backlog under contract, we also have a substantial number of projects in negotiation or pending award at any time.

Backlog for our marine segment at June 30, 20182019 was $184.6$477.0 million, as compared with $210.0$184.6 million at June 30, 2017.2018.

Liquidity and Capital Resources

Our primary liquidity needs are to finance our working capital, fund capital expenditures, and pursue strategic acquisitions. Historically, our source of liquidity has been cash provided by our operating activities and borrowings under our Credit Facility (as defined in Note 12 and below).

Our working capital position fluctuates from period to period due to normal increases and decreases in operational activity. At June 30, 20182019, our working capital was $72.2$44.6 million, as compared with $69.850.8 million at December 31, 20172018. Working capital at June 30, 2019 was reduced $5.7 million as a result of the implementation of ASC 842 which brought operating lease liabilities on to the balance sheet. As of June 30, 2018,2019, we had cash on hand of $6.3$2.8 million. Our borrowing capacity at June 30, 20182019 was approximately $31.3$20.6 million.



We expect to meet our future internal liquidity and working capital needs, and maintain or replace our equipment fleet through capital expenditure purchases and major repairs, from funds generated by our operating activities for at least the next 12 months.  We believe our cash position is adequate for our general business requirements discussed above and to service our debt.

The following table provides information regarding our cash flows and our capital expenditures for the three and six months ended June 30, 20182019 and 2017:2018:

Operating Activities. In the three months ended June 30, 2019, the Company's operations provided approximately $0.8 million of net cash, as compared with cash used in operations in the prior year period of approximately $6.1 million. The increase in cash between periods of $7.0 million was primarily attributable to a $2.8 million increase in non-cash items in the current year period as compared to the prior year period and an increase of $8.1 million of changes in working capital primarily driven by net increase in billings in excess of costs and estimated earnings, partially offset by an increase in accounts receivable and the $3.9 million decrease in net income in the current year period as compared to the prior year period.

In the six months ended June 30, 2018,2019, the Company's operations providedused approximately $4.5$1.1 million of net cash, inflows, as compared with cash provided by operations in the prior year period of approximately $20.1$4.5 million. The decrease in cash between periods of $15.6$5.6 million was primarily attributable to the $15.9 million decrease in net income, partially offset by a $7.9 million increase in non-cash items in the current year period as compared to the prior year period and an increase of $2.4 million of changes in working capital primarily driven by an increase in the balance of costsaccounts receivable, partially offset by a net increase in estimated earnings in excess of billings and a decrease in the billings in excess of costs and estimated earnings.earnings in the current year period as compared to the prior year period.

August 31, with the exception of the final swap, the existing interest rate swap is scheduled to expire and will be immediately replaced with a new interest rate swap until the expiration of the final swap on July 31, 2020. On December 6, 2018, the Company entered a sixth receive-variable, pay-fixed interest rate swaps to hedge the variability of interest payments. The sixth swap will begin with a notional amount of $27.0 million on July 31, 2020 will hedge the variability in the interest payments on 50% of the aggregate scheduled principal amount of the Regions Term Loan outstanding. The sixth swap is scheduled to expire on June 30, 2023. At inception, these interest rate swaps were designated as a cash flow hedge for hedge accounting, and as such, the effective portion of unrealized changes in market value are recorded in accumulated other comprehensive income (loss) and reclassified into earnings during the period in which the hedged forecasted transaction affects earnings. Gains and losses from hedge ineffectiveness are recognized in current earnings. The change in fair market value of the swaps for the six months endedas of June 30, 2018 was $0.32019 is approximately $1.1 million, net of tax.which is reflected in the balance sheet as a liability in Other non-current liabilities on the Consolidated Balance Sheets. The fair market value of the swaps as of June 30, 2018 was $0.4 million and net of tax was $0.3 million, which2019 is reflected as an asset in "Other non-current assets" on the Consolidated Balance Sheets.$(1.1) million. See Note 98 for more information regarding the fair value of the Company's derivative instruments.

Bonding Capacity

We are generally required to provide various types of surety bonds that provide additional security to our customers for our
performance under certain government and private sector contracts. Our ability to obtain surety bonds depends on our capitalization, working capital, past performance and external factors, including the capacity of the overall surety market. At June 30, 2018, our maximum2019, the capacity under our current bonding arrangement was at least $500 million, with approximately $213$300 million of remaining availability.projects being bonded.  We believe our strong balance sheet and working capital position will allow us to continue to access our bonding capacity.

Effect of Inflation

We are subject to the effects of inflation through increases in the cost of raw materials and other items, such as fuel, concrete, and steel. Due to the relative short-term duration of our projects, we are generally able to include anticipated price increases in the cost of our bids.


Item 3.                      Quantitative and Qualitative Disclosures about Market Risk

In the normal course of business, our results of operations are subject to risks related to fluctuation in commodity prices and fluctuations in interest rates. Historically, our exposure to foreign currency fluctuations has not been material and has been limited to temporary field accounts located in foreign countries where we perform work. Foreign currency fluctuations were immaterial in this reporting period.

Commodity price risk
We are subject to fluctuations in commodity prices for such items as concrete, steel products and fuel.  Although we routinely attempt to secure firm quotes from our suppliers, we generally do not hedge against increases in prices for commodity products.  Commodity price risks may have an impact on our results of operations due to the fixed-price nature of many of our contracts, although the short-term duration of our projects may allow us to include price increases in the costs of our bids.

Interest rate risk
At June 30, 2018,2019, we had $90.0$83.0 million in outstanding borrowings under our credit facility, with a weighted average interest rate over the three-monththree month period of 3.87%5.79%.  Also we have entered into a series of receive-variable, pay-fixed interest rate swaps to hedge the variability in the interest payments on 50% of the aggregate principal amount of the term loan component of the credit facility outstanding, beginning with a notional amount of $67.5 million. At inception, these interest rate swaps were designated as a cash flow hedge for hedge accounting. Our objectives in managing interest rate risk are to lower our overall borrowing costs and limit interest rate changes on our earnings and cash flows.  To achieve this, we closely monitor changes in interest rates and we utilize cash from operations to reduce our debt position, if warranted.
