Notes to Condensed Consolidated Financial Statements

(Tabular Amounts in thousands, Except for Share and per Share Amounts)

(Unaudited)

1. Description of Business and Basis of Presentation

Description of Business

Orion Marine Group, Inc., its subsidiaries and affiliates (hereafter collectively referred to as “Orion” or the “Company”) provide a broad range of marine construction services on, over and under the water along the Gulf Coast, the Atlantic Seaboard, the West Coast, Canada and in the Caribbean Basin, as well as have a presence in Australia and the Middle East.  Our heavy civil marine projects include marine transportation facilities; bridges and causeways; marine pipelines; mechanical and hydraulic dredging and specialty projects.  We are headquartered in Houston, Texas.

Although we describe our business in this report in terms of the services we provide, our base of customers and the geographic areas in which we operate, we have concluded that our operations comprise one reportable segment pursuant to Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 280 – Segment Reporting.  In making this determination, we considered that each project has similar characteristics, includes similar services, has similar types of customers and is subject to the same regulatory environment.  We organize, evaluate and manage our financial information around each project when making operating decisions and assessing our overall performance.

Basis of Presentation

The accompanying condensed 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 have been condensed or omitted.  Readers of this report should also read our consolidated financial statements and the notes thereto included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2012 (“2012 Form 10-K”) as well as Item 7 – Management’s Discussion and Analysis of Financial Condition and Results of Operations also included in our 2012 Form 10-K.

In the opinion of management, the accompanying unaudited condensed 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 three months ended March 31, 2013, are not necessarily indicative of the results that may be expected for the year ending December 31, 2013.

2. Summary of Significant Accounting Principles

The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States (“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.  

On an ongoing basis, the Company evaluates the significant accounting policies used to prepare its condensed consolidated financial statements, including, but not limited to, those related to:

• Revenue recognition from construction contracts;

• Allowance for doubtful accounts;

• Testing of goodwill and other long-lived assets for possible impairment;

• Income taxes;

• Self-insurance; and

• Stock based compensation.

7

Revenue Recognition

The Company records revenue on construction contracts for financial statement purposes on the percentage-of-completion method, measured by the percentage of 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 revenue reflects the original contract price adjusted for agreed upon change orders. Contract costs include all direct costs, such as material and labor, and those indirect costs related to contract performance such as payroll taxes and insurance. General and administrative costs are charged to expense as incurred. Unapproved claims are recognized as an increase in contract revenue only when the collection is deemed probable and if the amount can be reasonably estimated for purposes of calculating total profit or loss on long-term contracts. Incentive fees, if available, are billed to the customer based on the terms and conditions of the contract.  The Company records revenue and the unbilled receivable for claims to the extent of costs incurred and to the extent we believe related collection is probable and includes no profit on claims recorded. Changes in job performance, job conditions and estimated profitability, including those arising from final contract settlements, may result in revisions to costs and revenues and are recognized in the period in which the revisions are determined. Provisions for estimated losses on uncompleted contracts are made in the period in which such losses are determined, without regard to the percentage of completion. Revenue is recorded net of any sales taxes collected and paid on behalf of the customer, if applicable.

The current asset “costs and estimated earnings in excess of billings on uncompleted contracts” represents revenues recognized in excess of amounts billed, which management believes will be billed and collected within one year of the completion of the contract. The liability “billings in excess of costs and estimated earnings on uncompleted contracts” represents billings in excess of revenues recognized.

The Company’s projects are typically short in duration, and usually span a period of less than one year.  Historically, we have not combined or segmented contracts.

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 our cash balances in excess of federally insured limits.  Cash equivalents at March 31, 2013 and December 31, 2012 consisted primarily of money market mutual funds and overnight bank deposits.

Foreign Currencies

Historically, the Company’s exposure to foreign currency fluctuations has not been material and has been limited to temporary field accounts, located in countries where the Company performs work, which amounts were insignificant in either 2012 or 2011.

Risk Concentrations

Financial instruments that potentially subject the Company to concentrations of credit risk principally consist of cash and cash equivalents and 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 substantial portion of the Company’s operations may be 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 write-offs and allowances for doubtful accounts. The Company has significant investments in billed and unbilled receivables as of March 31, 2013. Billed receivables represent amounts billed upon the completion of small contracts and progress billings on large contracts in accordance with contract terms and milestones. Unbilled receivables on fixed-price contracts, which are included in costs in excess of billings, arise as revenues are recognized

8

under the percentage-of-completion method. Unbilled amounts on cost-reimbursement 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 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 March 31, 2013 and December 31, 2012, the Company had not recorded an allowance for doubtful accounts.

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.  Retention at March 31, 2013 totaled $8.5 million, of which $0.5 million is expected to be collected beyond 2014.  Retention at December 31, 2012 totaled $8.2 million.

At March 31, 2013, and December 31, 2012, the Company had approximately $1.4 million in long term receivables. These relate to items that are due the Company for work performed under contract, but are not expected to be collected within one year. Management continues to evaluate and assess these items for collectibility. At this time, no allowance has been recorded.

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 its carrying value, 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 the 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.  Liabilities, if any, are recognized when the expenditure is considered probable and the amount can be reasonably estimated.

Fair Value Measurements

We evaluate and present certain amounts included in the accompanying consolidated financial statements at “fair value” in accordance with GAAP, which requires us to base our estimates on assumptions 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.  In measuring fair value, we use the following inputs in the order of priority indicated:

Level I – Quoted prices in active markets for identical, unrestricted assets or liabilities.

Level II – Observable inputs other than Level I prices, such as (i) quoted prices for similar assets or liabilities; (ii) quoted prices in markets that have insufficient volume or infrequent transactions; and (iii) inputs that are derived principally from or corroborated by observable market data for substantially the full term of the assets or liabilities.

Level III – Unobservable inputs to the valuation methodology that are significant to the fair value measurement.

We generally apply 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

Inventory consists of parts and small equipment held for use in the ordinary course of business and is valued at the lower of cost or market using historical average cost. Where shipping and handling costs are incurred by us, these charges are included in inventory and charged to cost of contract revenue upon use.

9

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 trucks	3 to 5 years
Buildings and improvements	5 to 30 years
Construction equipment	3 to 15 years
Vessels and dredges	1 to 15 years
Office equipment	1 to 5 years

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

Dry-docking activities and costs are capitalized and amortized on the straight-line method over a period ranging from three to 15 years until the next scheduled dry-docking.  Dry-docking activities 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 activities 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 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 sheets and reported at the lower of the carrying amount or the fair value, less the costs to sell, and are no longer depreciated. In late 2012, several assets were identified and recorded as held for sale, with an expected disposition date within one year.

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 underlying net assets in the acquisition.  In accordance with U.S. GAAP, acquired goodwill is not amortized, but is subject to impairment testing at least annually or more frequently if events or circumstances indicate that the asset more likely than not may be impaired. New accounting guidance was recently issued that will allow the Company to qualitatively assess the likelihood that the carrying value of its reporting units is less than fair value in lieu of, or prior to, performance of step one of the impairment test process.

Intangible assets

Intangible assets that have finite lives continue to be subject to amortization.  In addition, the Company must evaluate the remaining useful life 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.

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

10

of grant using the Black-Scholes option-pricing model.  The fair value of restricted stock grants is equivalent to the fair value of the stock issued on the date 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.

Income Taxes

The Company determines its consolidated income tax provision using the asset and liability method prescribed by US 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 that 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 our consolidated tax return.    We evaluate and record 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 we operate.

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 Company maintains two levels of excess loss insurance coverage, totaling $100 million in excess of primary coverage. The Company’s excess loss coverage responds to most of its liability policies when a primary limit of $1 million has been exhausted; provided that the primary limit for Maritime Employer’s Liability is $10 million and the Watercraft Pollution Policy primary limit is $5 million.

Separately, the Company’s employee health care is provided through a trust, administered by a third party.  The Company funds the trust 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 our estimate.  We include any adjustments to such reserves in our consolidated results of operations in the period in which they become known.

The accrued liability for self-insured claims includes incurred but not reported losses of $3.4 million and $3.8 million at March 31, 2013 and December 31, 2012, respectively.

Recent Accounting Pronouncements

In July 2012, the Financial Accounting Standards Board ("FASB") issued amendments to the indefinite-lived intangible asset impairment guidance which provides an option for companies to use a qualitative approach to test indefinite-lived intangible assets for impairment if certain conditions are met. The amendments are effective for annual and interim indefinite-lived intangible asset

11

impairment tests performed for fiscal years beginning after September 15, 2012. The implementation of the amended accounting guidance has not had a material impact on our consolidated financial position or results of operations.

In February 2013, the FASB issued amendments to guidance for obligations resulting from joint and several liability arrangements. The amended guidance requires an entity to measure obligations resulting from joint and several liability arrangements for which the sum of (1) the amount of the obligation within the scope of this guidance is fixed at the reporting date, as the amount the reporting entity agreed to pay on the basis of its arrangement among its co-obligors and (2) any additional amount the reporting entity expects to pay on behalf of its co-obligors. The guidance also requires an entity to disclose the nature and amount of the obligation as well as other information about those obligations. The amendments should be applied retrospectively to all prior periods presented for obligations within the scope of guidance that exist at the beginning of an entity's fiscal year of adoption. The amendments are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013 (early adoption is permitted). The implementation of the amended accounting guidance is not expected to have a material impact on our consolidated financial position or results of operations.

In March 2013, the FASB issued amendments to address the accounting for the cumulative translation adjustment when a parent either sells a part or all of its investment in a foreign entity or no longer holds a controlling financial interest in a subsidiary or group of assets that is a nonprofit activity or a business within a foreign entity. The amendments are effective prospectively for fiscal years (and interim reporting periods within those years) beginning after December 15, 2013 (early adoption is permitted). The initial adoption has no impact on our consolidated financial position and results of operations.

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.    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 receivables (trade and retainage) at March 31, 2013 and December 31, 2012, respectively:

	March 31, 2013				December 31, 2012
Federal Government	$	11,794	31	%	$	7,375	14	%
State Governments	194		1	%	1,761		3	%
Local Governments	6,924		17	%	5,532		10	%
Private Companies	19,415		51	%	38,617		73	%
Total receivables	$	38,327	100	%	$	53,285	100	%

At March 31, 2013, the US Army Corps of Engineers and a private sector customer accounted for 16.7%, and 14.8% of total receivables. At December 31, 2012, two private sector customers accounted for 11.7% and 9.9% of total receivables.

Additionally, the table below represents concentrations of revenue by type of customer for the three months ended March 31, 2013, and 2012.

	Three months ended March 31,
	2013		%		2012		%
Federal	$	20,031	27	%	$	12,716	25	%
State	6,219		8	%	7,520		15	%
Local	17,234		23	%	11,116		22	%
Private	31,575		42	%	19,538		38	%
	$	75,059	100	%	$	50,890	100	%

In the three months ended March 31, 2013, the US Army Corps of Engineers generated 13.3% of total revenues. In the three months ended March 31, 2012, the US Army Corps of Engineers represented 21.0% of total revenues.

12

The Company does not believe that the loss of any one of these customers, other than the US Army Corps of Engineers, would have a material adverse effect on the Company and its subsidiaries and affiliates.

The Company’s long-lived assets are substantially located in the United States.

4. Contracts in Progress

Contracts in progress are as follows at March 31, 2013 and December 31, 2012:

	March 31, 2013			December 31, 2012
Costs incurred on uncompleted contracts	$	354,508		$	750,218
Estimated earnings	70,731			171,475
	425,239			921,693
Less: Billings to date	(422,060		)	(918,817		)
	$	3,179		$	2,876
Included in the accompanying consolidated balance sheet under the following captions:

Billings in excess of costs and estimated earnings on uncompleted contracts	(17,184		)	(16,369		)
	$	3,179		$	2,876

Contract costs include all direct costs, such as materials and labor, and those indirect costs related to contract performance such as payroll taxes and insurance. Provisions for estimated losses on uncompleted contracts are made in the period in which such estimated losses are determined. Changes in job performance, job conditions and estimated profitability may result in revisions to costs and income and are recognized in the period in which the revisions are determined. An amount equal to contract costs attributable to claims is included in revenues when realization is probable and the amount can be reliably estimated.

5. Property and Equipment

The following is a summary of property and equipment at March 31, 2013 and December 31, 2012:

	March 31, 2013			December 31, 2012
Automobiles and trucks	$	2,180		$	1,591
Building and improvements	22,828			22,037
Construction equipment	140,115			140,835
Dredges and dredging equipment	96,927			96,927
Office equipment	4,245			4,095
	266,295			265,485
Less: accumulated depreciation	(141,768		)	(136,556		)
Net book value of depreciable assets	124,527			128,929
Construction in progress	8,774			6,949
Land	14,793			14,793
	$	148,094		$	150,671

For the three months ended March 31, 2013, and 2012 , depreciation expense was $5.3 million and $5.4 million, respectively. Substantially all depreciation expense is included in the cost of contract revenue in the Company’s Condensed Consolidated Statements of Operations.  The assets of the Company are pledged as collateral under the Company's Credit Agreement (as defined in Note 10).

6. Inventory

Inventory at March 31, 2013 and December 31, 2012, of $5.1 million and $4.4 million respectively, consists of spare parts and small equipment held for use in the ordinary course of business.

13

Non-current inventory at March 31, 2013 and December 31, 2012 totaled $0.9 million in each period and consisted primarily of spare engines components kept on hand for the Company's dredging assets.

7. Fair Value

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, we believe that the carrying value of our accounts receivables, other current assets, accounts payables and other current liabilities approximate their fair values. We have a note receivable in the amount of $46,000, for which we believe that the carrying value approximates its fair value, and which bears interest at 10%. In addition, we have a long-term receivable in the amount of $1.4 million, which we believe that the carrying value of this receivable approximates its fair value.

The fair value of the Company’s reporting units (as needed for purposes of determining indications of impairment to the carrying value of goodwill) is determined using a weighted average of valuations based on market multiples, discounted cash flows, and consideration of our market capitalization.  In 2012, we acquired the assets of West Construction, which requires the fair value of the earnout liability to be re-assessed on a not less than quarterly basis. In the first quarter of 2013, the Company performed this re-assessment and did not change the fair value of its liability of $271,000.

The fair value of the Company's debt at March 31, 2013 and December 31, 2012 approximated its carrying value of $9.7 million and $12.6 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 Level 2 in the fair value hierarchy.

8. Goodwill and Intangible Assets

Goodwill

The table below summarizes changes in goodwill recorded by the Company during the periods ended March 31, 2013 and December 31, 2012:

	March 31, 2013		December 31, 2012
Beginning balance, January 1	$	34,817	$	32,168
Additions	—		2,649
Ending balance	$	34,817	$	34,817

No indicators of goodwill impairment were identified during the three months ended March 31, 2013.

Intangible assets

The tables below present the activity and amortizations of finite-lived intangible assets:

	Three months ended March 31,
	2013			2012
Intangible assets, January 1	$	7,602		$	6,900
Additions	—			—
Total intangible assets, end of period	7,602			6,900

Intangible assets that were acquired in 2012 as part of the purchase of West Construction amortize over a period of one to three years, as follows:

	2013		2014		2015
Amortization	$	299	$	111	$	97

9. Accrued Liabilities

Accrued liabilities at March 31, 2013 and December 31, 2012 consisted of the following:

	March 31, 2013		December 31, 2012
Accrued salaries, wages and benefits	$	3,311	$	3,552
Accrual for self-insurance liabilities	3,442		3,806
Property taxes	924		2,458
Other accrued expenses	2,742		2,640
	$	10,419	$	12,456

10. Long-term Debt and Line of Credit

The Company has a credit agreement (the "Credit Agreement") with Wells Fargo Bank, National Association, as administrative agent, and Wells Fargo Securities, LLC.

The Credit Agreement, as amended from time to time, provides for borrowings under a revolving line of credit and swingline loans, an accordian, and a term loan (together, the “Credit Facility”). The Credit Facility is guaranteed by the subsidiaries of the Company, secured by the assets of the Company, including stock held in its subsidiaries, and may be used to finance working capital, repay indebtedness, fund acquisitions, and for other general corporate purposes. Interest is computed based on the designation of the loans, and bear interest at either a prime-based interest rate or a LIBOR-based interest rate.  Principal balances drawn under the Credit Facility may be prepaid at any time, in whole or in part, without premium or penalty.  Amounts repaid under the revolving line of credit may be re-borrowed. All of the components of the Credit Facility mature on June 30, 2013. On April 30, 2013, the Company extended the maturity of its Credit Facility to June 30, 2014.

Provisions of the revolving line of credit and accordian

The Company has a maximum borrowing availability under the revolving line of credit and swingline loans (as defined in the Credit Agreement) of $35 million, with a $20 million sublimit for the issuance of letters of credit. An additional $25 million is available subject to the Lender's discretion. 

Revolving loans may be designated as prime rate based loans (“ABR Loans”) or Eurodollar Loans, at the Company’s request, and may be made in an integral multiple of $500,000, in the case of an ABR Loan, or $1 million in the case of a Eurodollar Loan.   Swingline loans may only be designated as ABR Loans, and may be made in amounts equal to integral multiples of $100,000.  The Company may convert, change or modify such designations from time to time.  

Borrowings are subject to a borrowing base, which is calculated as the sum of 80% of eligible accounts receivable, plus 90% of adjusted cash balances, as defined in the Credit Agreement. At March 31, 2013, our borrowing base reflected no limitation in borrowing availability.

At March 31, 2013, no amounts were outstanding under the revolver. Outstanding letters of credit, which totaled $742,000 at March 31, 2013, reduced our maximum borrowing availability to approximately $34.3 million.

Provisions of the term loan

At March 31, 2013, the term loan component of the Credit Facility totaled $9.7 million and is secured by specific dredge assets of the Company. Principal payments on the term loan, in the amount of $389,000, are due quarterly.

15

Financial covenants

Restrictive financial covenants under the Credit Facility include:

• A Tangible Net Worth covenant, with the minimum Tangible Net Worth requirement of a base amount of $180 million as of June 30, 2012, plus 50% of accumulated consolidated quarterly net income (if positive), plus 75% of all issuances of equity interests by Borrower during that quarter;

• A Profitability Covenant such that the Company shall not sustain a consolidated net loss for two consecutive fiscal quarters, commencing with the quarter ending September 30, 2012.

In addition, the Credit Facility contains events of default that are usual and customary for similar transactions, including non-payment of principal, interest or fees; inaccuracy of representations and warranties; violation of covenants; bankruptcy and insolvency events; and events constituting a change of control.

The Company is subject to a commitment fee, at a current rate of 0.25% of the unused portion of the maximum available to borrow under the Credit Facility. The commitment fee is payable quarterly in arrears.  

Interest at March 31, 2013, was based on a LIBOR-option interest rate of 2.75%. For the year ended December 31, 2012, the weighted average interest rate was 2.40%.

At March 31, 2013, the Company was in compliance with its financial covenants and expects to be in compliance in 2013.

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

11. 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 income (or loss) for the full year and records a quarterly tax provision in accordance with the anticipated annual rate. The effective rate for the three months ended March 31, 2013 and 2012 was 36.8% and 36% in each period, respectively. This differed from the Company's statutory rate of 35% primarily due to state income taxes and the non-deductibility of certain permanent items, such as incentive stock compensation expense.

	Current			Deferred			Total
Three months ended March 31, 2013
U.S. Federal	$	—		$	(532	)	$	(532	)
State and local	27			(135		)	(108		)
	$	27		$	(667	)	$	(640	)
Three months ended March 31, 2012
U.S. Federal	$	(3,440	)	$	163		$	(3,277	)
State and local	(21		)	(261		)	(282		)
	$	(3,461	)	$	(98	)	$	(3,559	)

In assessing the realizability of deferred tax assets at March 31, 2013, the Company considered whether it was more likely than not that some portion or all of the deferred tax assets will not be realized. The realization of deferred tax assets depends upon the generation of future taxable income, which includes the reversal of deferred tax liabilities related to depreciation, during the periods in which these temporary differences become deductible. As of March 31, 2013, the Company believes that all of the deferred tax assets will be utilized and therefore has not recorded a valuation allowance.

The Company has a net operating loss carryforward ("NOL") of approximately $2.4 million for state income tax reporting purposes due to the losses sustained in various states in 2011 and 2012. The Company believes it will be able to utilize these NOL's against future income, due to expiration dates well into the future, and therefore no valuation allowance has been established. For federal tax reporting purposes, the Company carried all of its 2011 NOL back to 2009 and 2010 and received approximately $13.1 million in cash against these tax years in 2012. Part of the loss generated in 2012 was carried back to 2010, and the Company's income tax receivable reflects this estimate. Approximately $4.8 million remains as a tax carryforward, which the Company believes it will be able to utilize before expiration.

16

The Company does not believe that its tax positions will significantly change due to any settlement and/or expiration of statutes of limitations prior to March 31, 2014.

12. (Loss) Earnings Per Share

Basic (loss) earnings per share are based on the weighted average number of common shares outstanding during each period. Diluted earnings per share are based on the weighted average number of common shares outstanding and the effect of all dilutive common stock equivalents during each period. 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 months ended March 31, 2013 and 2012, no potential common stock equivalents were included as the effect of such would be anti-dilutive.

The following table reconciles the denominators used in the computations of both basic and diluted loss per share:

	Three months ended March 31,
	2013	2012
Basic:
Weighted average shares outstanding	27,229,792	27,119,760
Diluted:
Total basic weighted average shares outstanding	27,229,792	27,119,760
Effect of dilutive securities:
Common stock options	—	—
Total weighted average shares outstanding assuming dilution	27,229,792	27,119,760
Anti-dilutive stock options	2,189,442	2,374,659
Shares of common stock issued from the exercise of stock options	33,966	2,226

13. Stock-Based Compensation

The Company's stock incentive plan, known as the 2011 Long Term Incentive Plan, or the "2011 LTIP", was approved by shareholders in May 2011 and is administered by the Compensation Committee of the Company’s Board of Directors. The 2011 LTIP authorized 3,000,000 shares to be issued under this plan. In general, the 2011 LTIP provides for grants of restricted stock and stock options to be issued with a per-share price equal to the fair market value of a share of common stock on the date of grant.  Option terms are specified at each grant date, but are generally are 10 years from the date of issuance.  Options generally vest over a three to five year period.  

In the three months ended March 31, 2013 and 2012 , compensation expense related to stock based awards outstanding was $582,000 and $774,000, respectively. In the first quarter of 2012, the Company granted options to purchase 262,051 shares of common stock, with a fair value of $4.08 per share. No equity awards of stock or options were granted in the first quarter of 2013.

In the three months ended March 31, 2013, 33,966 options were exercised, generating proceeds to the Company of approximately $206,000. In the three months ended March 31, 2012, the Company received proceeds of approximately $13,000 upon the exercise of 2,226 options.

At March 31, 2013, total unrecognized compensation expense related to unvested stock and options was approximately $4.6 million, which is expected to be recognized over a period of 2.73 years.

14.    Subsidiaries with Noncontrolling Owners' Interest

The Company acquired a two-thirds ownership interest in a foreign entity ("OMG-ME") as part of its acquisition of the assets of West Construction, Inc. in October 2012. The Company fully consolidates OMG-ME in its financial statements and records the remaining one-third ownership in its results of operations as "Net loss attributable to noncontrolling interest".

17

15. Commitments and Contingencies

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 proceedings, individually or in the aggregate, would be expected to have a material adverse effect on results of operations, cash flows or financial condition.

Item 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

CAUTIONARY STATEMENT CONCERNING FORWARD-LOOKING STATEMENTS

Unless the context otherwise indicates, all references in this quarterly report to “Orion,” “the company,” “we,” “our,” or “us” are to Orion Marine Group, Inc. and its subsidiaries taken as a whole.

Certain information in this Quarterly Report on Form 10-Q, including but not limited to Management’s Discussion and Analysis of Financial Condition and Results of Operations (“MD&A”), may constitute forward-looking statements as such term is defined within the meaning of the “safe harbor” provisions of Section 27A of the Securities Exchange Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended.

All statements other than statements of historical facts, including those that express a belief, expectation, or intention are forward-looking statements. The forward-looking statements may include projections and estimates concerning the timing and success of specific projects and our future production, revenues, income and capital spending. Our forward-looking statements are generally accompanied by words such as “estimate,” “project,” “predict,” “believe,” “expect,” “anticipate,” “potential,” “plan,” “goal” or other words that convey the uncertainty of future events or outcomes.

We have based these forward-looking statements on our current expectations and assumptions about future events. While our management considers these expectations and assumptions to be reasonable, they are inherently subject to significant business, economic, competitive, regulatory and other risks, contingencies and uncertainties, most of which are difficult to predict and many of which are beyond our control, including unforeseen productivity delays, levels of government funding or other governmental budgetary constraints, and contract cancellation at the discretion of the customer. These and other important factors, including those described under “Risk Factors” in Item 1A of the Company’s Annual Report on Form 10-K for the year ended December 31, 2012 (“2012 Form 10-K”) may cause our actual results, performance or achievements to differ materially from any future results, performance or achievements expressed or implied by these forward-looking statements.  The forward-looking statements in this quarterly report on Form 10-Q speak only as of the date of this report; we disclaim any obligation to update these statements unless required by securities law, and we caution you not to rely on them unduly.

MD&A provides a narrative analysis explaining the reasons for material changes in the Company’s (i) financial condition since the most recent fiscal year-end, and (ii) results of operations during the current fiscal year-to-date period and current fiscal quarter as compared to the corresponding periods of the preceding fiscal year.  In order to better understand such changes, this MD&A should be read in conjunction with the Company’s fiscal 2012 audited consolidated financial statements and notes thereto included in its 2012 Form 10-K, Item 7 Management’s Discussion and Analysis of Financial Condition and Results of Operations included in our 2012 Form 10-K  and with our unaudited financial statements and related notes appearing elsewhere in this quarterly report.

Overview

We are a leading marine specialty contractor serving the heavy civil marine infrastructure market. We provide a broad range of marine construction and specialty services on, over and under the water along the Gulf Coast, the Atlantic Seaboard, the West Coast, Canada and the Caribbean Basin, as well as have a presence in Australia and the Middle East. Our customers include federal, state and municipal governments, the combination of which accounted for approximately 58% of our revenue in the three months ended March 31, 2013, as well as private commercial and industrial enterprises. We are headquartered in Houston, Texas.

Our contracts are obtained primarily through competitive bidding in response to “requests for proposals” by federal, state and local agencies and through negotiation with private parties. Our bidding activity and strategies are affected by such factors as backlog, current utilization of equipment and other resources, 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. 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 and work stoppages due to weather and environmental restrictions;

• availability and skill level of workers; and

• a change in availability and proximity of equipment and materials.

19

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

First quarter 2013 recap and 2013 Outlook

In the first quarter of 2013, we were pleased with the level of bid activity, specifically in the private sector. In addition, we were able to sustain construction equipment utilization this quarter, although the utilization of our dredging fleet fell due to gaps in the schedule of projects involving dredging services, as well as seasonal fluctuations. Our revenues increased by 47.5% as compared with the first quarter last year, when revenues were significantly impacted by gaps between projects.

Our overall outlook for 2013 remains optimistic. Our tracking database of future projects of interest remains strong for the foreseeable future. We continue to see new bid opportunities in the private sector, reflecting increases in capital projects, both in new construction and refurbishment of existing infrastructure. Bridge projects funded by various state departments of transportation, as well as projects led by local port authorities, continue to be let at normal levels. However, current and future lettings from the US Army Corps of Engineers remain inconsistent and uncertain, which continues to put pressure on the utilization of our dredging assets. With the passage of a continuing resolution by Congress to fund the federal government for the reminder of its fiscal year, we are optimistic that the US Army Corps of Engineers will be able to let projects over the next six months.

In the long-term, we continue to see positive trends in demands for our services in our end markets, including:

• General demand to repair and improve degrading US marine infrastructure;

• Language in the Transportation Bill urging action for resolution of the discrepancy between Harbor Maintenance tax collections and expenditures;

• Renewed focus on coastal rehabilitation along the Gulf Coast

• Expected increases in cargo volume and future demands from larger ships transiting the Panama Canal will require ports along the Gulf Coast and Atlantic Seaboard to perform additional dredging services and expand port infrastructure; and

• Improving economic conditions and increased activity in the petrochemical industry will necessitate capital expenditures , including larger projects as well as maintenance call-out work.

Our focus in 2013 will be to concentrate on our core business objectives; to manage our business effectively and efficiently, continue to maintain a strong backlog while maintaining our pricing discipline; to closely monitor the costs of our operations; and to maintain our strong balance sheet.

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 a year, our backlog at any point in time usually represents only a portion of the revenue that we expect to realize during a twelve 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 materially 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 at March 31, 2013 was $150.4 million, as compared with $184.1 million at December 31, 2012.

Revenues for the three months ended March 31, 2013 increased approximately 47.5% as a result of increased volume of work due to adjustments in our pricing strategies, as compared with the prior year period, when revenues were substantially impacted by gaps between projects, as well as a slowdown in lettings of Federal projects, particularly those involving dredging services. In the current year period, we continued work on several large projects for private sector customers, and revenue generated from private customers represented 42% of total revenues in the period, as compared with 38% in the prior year period. Contract revenue generated from public sector customers represented 58% of total revenues in the first quarter of 2013, as compared with 62% in the comparable period last year. We view these shifts in revenue from one sector to another as normal in the marine construction business.

Gross Profit.   Gross profit was $5.8 million in the first quarter ended March 31, 2013, as compared with a negative $2.8 million in the first quarter last year, and was primarily related to better utilization of equipment, and to certain cost savings on jobs in progress or nearing completion. Gross profit was driven down in the prior year period due to underutilized equipment and to labor expense for crews idled when projects completed. Gross margin in the first quarter was 7.8% , as compared with a negative (5.6)% last year. As measured by cost, our self performance was 83% in the current year period, as compared with 85% in the three months ended March 31, 2012. The 2% reduction in our self-performance rate indicates an increase in the percent of work that was subcontracted to third parties, and is reflective of the types of jobs in progress at any point in time.

Selling, General and Administrative Expense. Selling, general and administrative ("SG&A") expenses were $7.7 million, an increase of $0.6 million, or 8.5%, as compared with the prior year period, The increase was primarily related to additional overhead expenses related to the acquisition in late 2012.

Income Tax Benefit.  We have estimated our effective tax rate at 36.8% for 2013. This differs from the statutory rate of 35%, due to permanent differences, including incentive stock option expense, and to benefits expected from state income taxes. Our effective rate for the in the period ended March 31, 2012 was 36%.  

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 below).

Our working capital position fluctuates from period to period due to normal increases and decreases in operational activity. At March 31, 2013, our working capital was $65.9 million, as compared with $55.8 million at December 31, 2012. As of March 31,

21

2013, we had cash on hand of $45.9 million. Availability under our revolving credit facility was subject to a borrowing base, which did not limit our borrowing availability of approximately $34.3 million.

We expect to meet our future internal liquidity and working capital needs, and maintain our equipment fleet through capital expenditure purchases and major repairs, from funds generated in 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 months ended March 31, 2013 and 2012:

	Three months ended March 31,
	2013			2012
Cash flows provided by (used in) operating activities	$	8,162		$	(20,025	)
Cash flows used in investing activities	$	(2,678	)	$	(16,220	)
Cash flows (used in) provided by financing activities	$	(2,683	)	$	13,013
Capital expenditures (included in investing activities above)	$	(2,691	)	$	(16,260	)

Operating Activities. In the first quarter of 2013, our operations provided approximately $8.2 million in net cash inflows, as compared with cash used by operations in the prior year period of $20.0 million. The change in cash between periods was related to:

• a decrease in our net loss of approximately $5.2 million;

• a decrease in trade accounts receivable balances, related to the timing of billings to customers, as compared with net collections of receivables in the prior year period, which resulted in a net inflow of cash between periods of $19.7 million;

• net outflow of cash of $4.0 million between periods related to billings to and payments from customers for costs that cannot be billed, or receipt of payments for items such as mobilization at project commencement;

• outflow of cash in the prior year period of $13.9 million of cash as set aside in accordance with the terms of the Credit Facility

• receipt of $0.4 million in cash related to prior year tax refunds and $3.5 million related to the carryback of prior year tax losses;

• changes in other working capital components, including trade payables, which are related to the composition of projects in process, and which resulted in a net outflow of cash between 2013 and 2012 of $9.9 million

• changes in non-cash components of approximately $0.6 million, primarily related to changes in our net deferred tax liability, resulting from an increase in our net operating loss carryforwards in the current year.

Changes in working capital are normal within our business and are not necessarily indicative of any fundamental change within working capital components or trend in the underlying business.  

Investing Activities. Capital asset additions and betterments to our fleet were $2.7 million in the first three months of 2013, as compared with $16.2 million in 2012, which included the purchase of approximately 18 acres of land and buildings in Tampa, Florida.

Financing Activities. In the prior year period, we funded the purchase of land and buildings in Tampa, Florida from our Credit Facility through draws totaling $13.0 million, of which $10.9 million was converted to a term loan. We have made scheduled installment payments on the term loan which which has reduced the balance to $9.7 million.

Sources of Capital

The Company has a credit agreement (the "Credit Agreement") with Wells Fargo Bank, National Association, as administrative agent, and Wells Fargo Securities, LLC.

The Credit Agreement, as amended from time to time, provides for borrowings under a revolving line of credit and swingline loans, an accordian, and a term loan (together, the “Credit Facility”). The Credit Facility is guaranteed by the subsidiaries of the Company, secured by the assets of the Company, including stock held in its subsidiaries, and may be used to finance working capital, repay indebtedness, fund acquisitions, and for other general corporate purposes. Interest is computed based on the designation of the loans, and bear interest at either a prime-based interest rate or a LIBOR-based interest rate.  Principal balances drawn under the Credit Facility may be prepaid at any time, in whole or in part, without premium or

22

penalty.  Amounts repaid under the revolving line of credit may be re-borrowed. All of the components of the Credit Facility mature on June 30, 2013. On April 30, 2013, the Company extended the maturity of its Credit Facility to June 30, 2014.

Provisions of the revolving line of credit and accordian

The Company has a maximum borrowing availability under the revolving line of credit and swingline loans (as defined in the Credit Agreement) of $35 million, with a $20 million sublimit for the issuance of letters of credit. An additional $25 million is available subject to the Lender's discretion. 

Revolving loans may be designated as prime rate based loans (“ABR Loans”) or Eurodollar Loans, at the Company’s request, and may be made in an integral multiple of $500,000, in the case of an ABR Loan, or $1 million in the case of a Eurodollar Loan.   Swingline loans may only be designated as ABR Loans, and may be made in amounts equal to integral multiples of $100,000.  The Company may convert, change or modify such designations from time to time.  

Borrowings are subject to a borrowing base, which is calculated as the sum of 80% of eligible accounts receivable, plus 90% of adjusted cash balances, as defined in the Credit Agreement. At March 31, 2013, our borrowing base reflected no limitation in borrowing availability.

At March 31, 2013, no amounts were outstanding under the revolver. Outstanding letters of credit, which totaled $742,000 at March 31, 2013, reduced our maximum borrowing availability to approximately $34.3 million.

Provisions of the term loan

At March 31, 2013, the term loan component of the Credit Facility totaled $9.7 million and is secured by specific dredge assets of the Company. Principal payments on the term loan, in the amount of $389,000, are due quarterly.

Financial covenants

Restrictive financial covenants under the Credit Facility include:

• A Tangible Net Worth covenant, with the minimum Tangible Net Worth requirement of a base amount of $180 million as of June 30, 2012, plus 50% of accumulated consolidated quarterly net income (if positive), plus 75% of all issuances of equity interests by Borrower during that quarter;

• A Profitability Covenant such that the Company shall not sustain a consolidated net loss for two consecutive fiscal quarters, commencing with the quarter ending September 30, 2012.

In addition, the Credit Facility contains events of default that are usual and customary for similar transactions, including non-payment of principal, interest or fees; inaccuracy of representations and warranties; violation of covenants; bankruptcy and insolvency events; and events constituting a change of control.

The Company is subject to a commitment fee, at a current rate of 0.25% of the unused portion of the maximum available to borrow under the Credit Facility. The commitment fee is payable quarterly in arrears.  

Interest at March 31, 2013, was based on a LIBOR-option interest rate of 2.75%. For the year ended December 31, 2012, the weighted average interest rate was 2.40%.

At March 31, 2013, the Company was in compliance with its financial covenants and expects to be in compliance in 2013.

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

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 March 31, 2013, we believe our capacity under our current bonding arrangement was in excess of $400 million, of which we had approximately $100 million in surety bonds outstanding.  We believe our strong balance sheet and working capital position will allow us to continue to access our bonding capacity.

23

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. 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

We do not enter into derivative financial instruments for trading, speculation or other purposes that would expose the Company to 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.

Commodity price risk

We are subject to fluctuations in commodity prices for concrete, steel products and fuel.  Although we attempt to secure firm quotes from our suppliers, we generally do not hedge against increases in prices for concrete, steel and fuel.  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 March 31, 2013, we had $9.7 million in outstanding borrowings under our revolving credit facility, with a weighted average interest rate over the three month period of 2.75%.  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.

Item 4.                      Controls and Procedures

• Evaluation of Disclosure Controls and Procedures.  As required, the Company’s management, with the participation of its Chief Executive Officer and Chief Financial Officer, have conducted an evaluation of the effectiveness of disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended) as of the end of the period covered by this quarterly report.  Based on that evaluation, such officers have concluded that the disclosure controls and procedures are effective.

• Changes in Internal Controls.  There have been no changes in our internal controls over financial reporting during the period covered by this report that have materially affected, or are reasonably likely to materially affect, our internal controls over financial reporting.

Concentration of Risk and Enterprise Wide Disclosures

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 receivables (trade and retainage) at March 31, 2013 and December 31, 2012, respectively:

	March 31, 2013				December 31, 2012
Federal Government	$	11,794	31	%	$	7,375	14	%
State Governments	194		1	%	1,761		3	%
Local Governments	6,924		17	%	5,532		10	%
Private Companies	19,415		51	%	38,617		73	%
Total receivables	$	38,327	100	%	$	53,285	100	%

At March 31, 2013, the US Army Corps of Engineers and a private sector customer accounted for 16.7%, and 14.8% of total receivables. At December 31, 2012, two private sector customers accounted for 11.7% and 9.9% of total receivables.

Additionally, the table below represents concentrations of revenue by type of customer for the three months ended March 31, 2013, and 2012.

	$	75,059	100	%	$	50,890	100	%

In the three months ended March 31, 2013, the US Army Corps of Engineers generated 13.3% of total revenues. In the three months ended March 31, 2012, the US Army Corps of Engineers represented 21.0% of total revenues.

The Company does not believe that the loss of any one of these customers, other than the US Army Corps of Engineers, would have a material adverse effect on the Company and its subsidiaries and affiliates.

The Company’s long-lived assets are substantially located in the United States.

Summary of Significant Accounting Policies

Accounting Policies [Abstract]

Summary of Significant Accounting Principles

Summary of Significant Accounting Principles

The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States (“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.  

On an ongoing basis, the Company evaluates the significant accounting policies used to prepare its condensed consolidated financial statements, including, but not limited to, those related to:

• Revenue recognition from construction contracts;

• Allowance for doubtful accounts;

• Testing of goodwill and other long-lived assets for possible impairment;

• Income taxes;

• Self-insurance; and

• Stock based compensation.

Revenue Recognition

The Company records revenue on construction contracts for financial statement purposes on the percentage-of-completion method, measured by the percentage of 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 revenue reflects the original contract price adjusted for agreed upon change orders. Contract costs include all direct costs, such as material and labor, and those indirect costs related to contract performance such as payroll taxes and insurance. General and administrative costs are charged to expense as incurred. Unapproved claims are recognized as an increase in contract revenue only when the collection is deemed probable and if the amount can be reasonably estimated for purposes of calculating total profit or loss on long-term contracts. Incentive fees, if available, are billed to the customer based on the terms and conditions of the contract.  The Company records revenue and the unbilled receivable for claims to the extent of costs incurred and to the extent we believe related collection is probable and includes no profit on claims recorded. Changes in job performance, job conditions and estimated profitability, including those arising from final contract settlements, may result in revisions to costs and revenues and are recognized in the period in which the revisions are determined. Provisions for estimated losses on uncompleted contracts are made in the period in which such losses are determined, without regard to the percentage of completion. Revenue is recorded net of any sales taxes collected and paid on behalf of the customer, if applicable.

The current asset “costs and estimated earnings in excess of billings on uncompleted contracts” represents revenues recognized in excess of amounts billed, which management believes will be billed and collected within one year of the completion of the contract. The liability “billings in excess of costs and estimated earnings on uncompleted contracts” represents billings in excess of revenues recognized.

The Company’s projects are typically short in duration, and usually span a period of less than one year.  Historically, we have not combined or segmented contracts.

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 our cash balances in excess of federally insured limits.  Cash equivalents at March 31, 2013 and December 31, 2012 consisted primarily of money market mutual funds and overnight bank deposits.

Foreign Currencies

Historically, the Company’s exposure to foreign currency fluctuations has not been material and has been limited to temporary field accounts, located in countries where the Company performs work, which amounts were insignificant in either 2012 or 2011.

Risk Concentrations

Financial instruments that potentially subject the Company to concentrations of credit risk principally consist of cash and cash equivalents and 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 substantial portion of the Company’s operations may be 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 write-offs and allowances for doubtful accounts. The Company has significant investments in billed and unbilled receivables as of March 31, 2013. Billed receivables represent amounts billed upon the completion of small contracts and progress billings on large contracts in accordance with contract terms and milestones. Unbilled receivables on fixed-price contracts, which are included in costs in excess of billings, arise as revenues are recognized under the percentage-of-completion method. Unbilled amounts on cost-reimbursement 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 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 March 31, 2013 and December 31, 2012, the Company had not recorded an allowance for doubtful accounts.

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.  Retention at March 31, 2013 totaled $8.5 million, of which $0.5 million is expected to be collected beyond 2014.  Retention at December 31, 2012 totaled $8.2 million.

At March 31, 2013, and December 31, 2012, the Company had approximately $1.4 million in long term receivables. These relate to items that are due the Company for work performed under contract, but are not expected to be collected within one year. Management continues to evaluate and assess these items for collectibility. At this time, no allowance has been recorded.

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 its carrying value, 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 the 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.  Liabilities, if any, are recognized when the expenditure is considered probable and the amount can be reasonably estimated.

Fair Value Measurements

We evaluate and present certain amounts included in the accompanying consolidated financial statements at “fair value” in accordance with GAAP, which requires us to base our estimates on assumptions 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.  In measuring fair value, we use the following inputs in the order of priority indicated:

Level I – Quoted prices in active markets for identical, unrestricted assets or liabilities.

Level II – Observable inputs other than Level I prices, such as (i) quoted prices for similar assets or liabilities; (ii) quoted prices in markets that have insufficient volume or infrequent transactions; and (iii) inputs that are derived principally from or corroborated by observable market data for substantially the full term of the assets or liabilities.

Level III – Unobservable inputs to the valuation methodology that are significant to the fair value measurement.

We generally apply 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

Inventory consists of parts and small equipment held for use in the ordinary course of business and is valued at the lower of cost or market using historical average cost. Where shipping and handling costs are incurred by us, these charges are included in inventory and charged to cost of contract revenue upon use.

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 trucks	3 to 5 years
Buildings and improvements	5 to 30 years
Construction equipment	3 to 15 years
Vessels and dredges	1 to 15 years
Office equipment	1 to 5 years

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

Dry-docking activities and costs are capitalized and amortized on the straight-line method over a period ranging from three to 15 years until the next scheduled dry-docking.  Dry-docking activities 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 activities 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 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 sheets and reported at the lower of the carrying amount or the fair value, less the costs to sell, and are no longer depreciated. In late 2012, several assets were identified and recorded as held for sale, with an expected disposition date within one year.

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 underlying net assets in the acquisition.  In accordance with U.S. GAAP, acquired goodwill is not amortized, but is subject to impairment testing at least annually or more frequently if events or circumstances indicate that the asset more likely than not may be impaired. New accounting guidance was recently issued that will allow the Company to qualitatively assess the likelihood that the carrying value of its reporting units is less than fair value in lieu of, or prior to, performance of step one of the impairment test process.

Intangible assets

Intangible assets that have finite lives continue to be subject to amortization.  In addition, the Company must evaluate the remaining useful life 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.

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 fair value of restricted stock grants is equivalent to the fair value of the stock issued on the date 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.

Income Taxes

The Company determines its consolidated income tax provision using the asset and liability method prescribed by US 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 that 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 our consolidated tax return.    We evaluate and record 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 we operate.

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 Company maintains two levels of excess loss insurance coverage, totaling $100 million in excess of primary coverage. The Company’s excess loss coverage responds to most of its liability policies when a primary limit of $1 million has been exhausted; provided that the primary limit for Maritime Employer’s Liability is $10 million and the Watercraft Pollution Policy primary limit is $5 million.

Separately, the Company’s employee health care is provided through a trust, administered by a third party.  The Company funds the trust 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 our estimate.  We include any adjustments to such reserves in our consolidated results of operations in the period in which they become known.

The accrued liability for self-insured claims includes incurred but not reported losses of $3.4 million and $3.8 million at March 31, 2013 and December 31, 2012, respectively.

Recent Accounting Pronouncements

In July 2012, the Financial Accounting Standards Board ("FASB") issued amendments to the indefinite-lived intangible asset impairment guidance which provides an option for companies to use a qualitative approach to test indefinite-lived intangible assets for impairment if certain conditions are met. The amendments are effective for annual and interim indefinite-lived intangible asset impairment tests performed for fiscal years beginning after September 15, 2012. The implementation of the amended accounting guidance has not had a material impact on our consolidated financial position or results of operations.

In February 2013, the FASB issued amendments to guidance for obligations resulting from joint and several liability arrangements. The amended guidance requires an entity to measure obligations resulting from joint and several liability arrangements for which the sum of (1) the amount of the obligation within the scope of this guidance is fixed at the reporting date, as the amount the reporting entity agreed to pay on the basis of its arrangement among its co-obligors and (2) any additional amount the reporting entity expects to pay on behalf of its co-obligors. The guidance also requires an entity to disclose the nature and amount of the obligation as well as other information about those obligations. The amendments should be applied retrospectively to all prior periods presented for obligations within the scope of guidance that exist at the beginning of an entity's fiscal year of adoption. The amendments are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013 (early adoption is permitted). The implementation of the amended accounting guidance is not expected to have a material impact on our consolidated financial position or results of operations.

In March 2013, the FASB issued amendments to address the accounting for the cumulative translation adjustment when a parent either sells a part or all of its investment in a foreign entity or no longer holds a controlling financial interest in a subsidiary or group of assets that is a nonprofit activity or a business within a foreign entity. The amendments are effective prospectively for fiscal years (and interim reporting periods within those years) beginning after December 15, 2013 (early adoption is permitted). The initial adoption has no impact on our consolidated financial position and results of operations.

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.

Summary of Significant Accounting Policies (Policies)

3 Months Ended

Mar. 31, 2013

Accounting Policies [Abstract]

Reclassifications

n the opinion of management, the accompanying unaudited condensed 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 three months ended March 31, 2013, are not necessarily indicative of the results that may be expected for the year ending December 31, 2013.

Revenue Recognition

Revenue Recognition

The Company records revenue on construction contracts for financial statement purposes on the percentage-of-completion method, measured by the percentage of 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 revenue reflects the original contract price adjusted for agreed upon change orders. Contract costs include all direct costs, such as material and labor, and those indirect costs related to contract performance such as payroll taxes and insurance. General and administrative costs are charged to expense as incurred. Unapproved claims are recognized as an increase in contract revenue only when the collection is deemed probable and if the amount can be reasonably estimated for purposes of calculating total profit or loss on long-term contracts. Incentive fees, if available, are billed to the customer based on the terms and conditions of the contract.  The Company records revenue and the unbilled receivable for claims to the extent of costs incurred and to the extent we believe related collection is probable and includes no profit on claims recorded. Changes in job performance, job conditions and estimated profitability, including those arising from final contract settlements, may result in revisions to costs and revenues and are recognized in the period in which the revisions are determined. Provisions for estimated losses on uncompleted contracts are made in the period in which such losses are determined, without regard to the percentage of completion. Revenue is recorded net of any sales taxes collected and paid on behalf of the customer, if applicable.

The current asset “costs and estimated earnings in excess of billings on uncompleted contracts” represents revenues recognized in excess of amounts billed, which management believes will be billed and collected within one year of the completion of the contract. The liability “billings in excess of costs and estimated earnings on uncompleted contracts” represents billings in excess of revenues recognized.

Classification of Current Assets and Liabilities

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

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 our cash balances in excess of federally insured limits.  Cash equivalents at March 31, 2013 and December 31, 2012 consisted primarily of money market mutual funds and overnight bank deposits.

Foreign Currencies

Foreign Currencies

Historically, the Company’s exposure to foreign currency fluctuations has not been material and has been limited to temporary field accounts, located in countries where the Company performs work, which amounts were insignificant in either 2012 or 2011.

Risk Concentrations

Risk Concentrations

Financial instruments that potentially subject the Company to concentrations of credit risk principally consist of cash and cash equivalents and 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 substantial portion of the Company’s operations may be 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

Accounts receivable are stated at the historical carrying value, less write-offs and allowances for doubtful accounts. The Company has significant investments in billed and unbilled receivables as of March 31, 2013. Billed receivables represent amounts billed upon the completion of small contracts and progress billings on large contracts in accordance with contract terms and milestones. Unbilled receivables on fixed-price contracts, which are included in costs in excess of billings, arise as revenues are recognized under the percentage-of-completion method. Unbilled amounts on cost-reimbursement 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 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 March 31, 2013 and December 31, 2012, the Company had not recorded an allowance for doubtful accounts.

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.  Retention at March 31, 2013 totaled $8.5 million, of which $0.5 million is expected to be collected beyond 2014.  Retention at December 31, 2012 totaled $8.2 million.

At March 31, 2013, and December 31, 2012, the Company had approximately $1.4 million in long term receivables. These relate to items that are due the Company for work performed under contract, but are not expected to be collected within one year. Management continues to evaluate and assess these items for collectibility. At this time, no allowance has been recorded.

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 its carrying value, 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 the open bid process, and therefore advertising costs are not a significant component of expense.  Advertising costs are expensed as incurred.

Environmental Costs

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.  Liabilities, if any, are recognized when the expenditure is considered probable and the amount can be reasonably estimated.

Fair Value Measurements

Fair Value Measurements

We evaluate and present certain amounts included in the accompanying consolidated financial statements at “fair value” in accordance with GAAP, which requires us to base our estimates on assumptions 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.  In measuring fair value, we use the following inputs in the order of priority indicated:

Level I – Quoted prices in active markets for identical, unrestricted assets or liabilities.

Level II – Observable inputs other than Level I prices, such as (i) quoted prices for similar assets or liabilities; (ii) quoted prices in markets that have insufficient volume or infrequent transactions; and (iii) inputs that are derived principally from or corroborated by observable market data for substantially the full term of the assets or liabilities.

Level III – Unobservable inputs to the valuation methodology that are significant to the fair value measurement.

We generally apply 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

Inventory

Inventory consists of parts and small equipment held for use in the ordinary course of business and is valued at the lower of cost or market using historical average cost. Where shipping and handling costs are incurred by us, these charges are included in inventory and charged to cost of contract revenue upon use.

Property and Equipment

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 trucks	3 to 5 years
Buildings and improvements	5 to 30 years
Construction equipment	3 to 15 years
Vessels and dredges	1 to 15 years
Office equipment	1 to 5 years

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

Dry-docking activities and costs are capitalized and amortized on the straight-line method over a period ranging from three to 15 years until the next scheduled dry-docking.  Dry-docking activities 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 activities 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 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 sheets and reported at the lower of the carrying amount or the fair value, less the costs to sell, and are no longer depreciated. In late 2012, several assets were identified and recorded as held for sale, with an expected disposition date within one year.

Goodwill

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 underlying net assets in the acquisition.  In accordance with U.S. GAAP, acquired goodwill is not amortized, but is subject to impairment testing at least annually or more frequently if events or circumstances indicate that the asset more likely than not may be impaired. New accounting guidance was recently issued that will allow the Company to qualitatively assess the likelihood that the carrying value of its reporting units is less than fair value in lieu of, or prior to, performance of step one of the impairment test process.

Intangible assets

Intangible assets that have finite lives continue to be subject to amortization.  In addition, the Company must evaluate the remaining useful life 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

Stock-Based Compensation

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 fair value of restricted stock grants is equivalent to the fair value of the stock issued on the date 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.

Income Taxes

Income Taxes

The Company determines its consolidated income tax provision using the asset and liability method prescribed by US 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 that 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 our consolidated tax return.    We evaluate and record 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 we operate.

Insurance Coverage

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 Company maintains two levels of excess loss insurance coverage, totaling $100 million in excess of primary coverage. The Company’s excess loss coverage responds to most of its liability policies when a primary limit of $1 million has been exhausted; provided that the primary limit for Maritime Employer’s Liability is $10 million and the Watercraft Pollution Policy primary limit is $5 million.

Separately, the Company’s employee health care is provided through a trust, administered by a third party.  The Company funds the trust 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 our estimate.  We include any adjustments to such reserves in our consolidated results of operations in the period in which they become known.

New Accounting Pronouncements

Accounting Pronouncements

In July 2012, the Financial Accounting Standards Board ("FASB") issued amendments to the indefinite-lived intangible asset impairment guidance which provides an option for companies to use a qualitative approach to test indefinite-lived intangible assets for impairment if certain conditions are met. The amendments are effective for annual and interim indefinite-lived intangible asset impairment tests performed for fiscal years beginning after September 15, 2012. The implementation of the amended accounting guidance has not had a material impact on our consolidated financial position or results of operations.

In February 2013, the FASB issued amendments to guidance for obligations resulting from joint and several liability arrangements. The amended guidance requires an entity to measure obligations resulting from joint and several liability arrangements for which the sum of (1) the amount of the obligation within the scope of this guidance is fixed at the reporting date, as the amount the reporting entity agreed to pay on the basis of its arrangement among its co-obligors and (2) any additional amount the reporting entity expects to pay on behalf of its co-obligors. The guidance also requires an entity to disclose the nature and amount of the obligation as well as other information about those obligations. The amendments should be applied retrospectively to all prior periods presented for obligations within the scope of guidance that exist at the beginning of an entity's fiscal year of adoption. The amendments are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013 (early adoption is permitted). The implementation of the amended accounting guidance is not expected to have a material impact on our consolidated financial position or results of operations.

In March 2013, the FASB issued amendments to address the accounting for the cumulative translation adjustment when a parent either sells a part or all of its investment in a foreign entity or no longer holds a controlling financial interest in a subsidiary or group of assets that is a nonprofit activity or a business within a foreign entity. The amendments are effective prospectively for fiscal years (and interim reporting periods within those years) beginning after December 15, 2013 (early adoption is permitted). The initial adoption has no impact on our consolidated financial position and results of operations.

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.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Description of Business and Basis of Presentation

Description of Business

Orion Marine Group, Inc., its subsidiaries and affiliates (hereafter collectively referred to as “Orion” or the “Company”) provide a broad range of marine construction services on, over and under the water along the Gulf Coast, the Atlantic Seaboard, the West Coast, Canada and in the Caribbean Basin, as well as have a presence in Australia and the Middle East.  Our heavy civil marine projects include marine transportation facilities; bridges and causeways; marine pipelines; mechanical and hydraulic dredging and specialty projects.  We are headquartered in Houston, Texas.

Although we describe our business in this report in terms of the services we provide, our base of customers and the geographic areas in which we operate, we have concluded that our operations comprise one reportable segment pursuant to Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 280 – Segment Reporting.  In making this determination, we considered that each project has similar characteristics, includes similar services, has similar types of customers and is subject to the same regulatory environment.  We organize, evaluate and manage our financial information around each project when making operating decisions and assessing our overall performance.

Basis of Presentation

The accompanying condensed 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 have been condensed or omitted.  Readers of this report should also read our consolidated financial statements and the notes thereto included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2012 (“2012 Form 10-K”) as well as Item 7 – Management’s Discussion and Analysis of Financial Condition and Results of Operations also included in our 2012 Form 10-K.

In the opinion of management, the accompanying unaudited condensed 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 three months ended March 31, 2013, are not necessarily indicative of the results that may be expected for the year ending December 31, 2013.

Income Taxes

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 income (or loss) for the full year and records a quarterly tax provision in accordance with the anticipated annual rate. The effective rate for the three months ended March 31, 2013 and 2012 was 36.8% and 36% in each period, respectively. This differed from the Company's statutory rate of 35% primarily due to state income taxes and the non-deductibility of certain permanent items, such as incentive stock compensation expense.

In assessing the realizability of deferred tax assets at March 31, 2013, the Company considered whether it was more likely than not that some portion or all of the deferred tax assets will not be realized. The realization of deferred tax assets depends upon the generation of future taxable income, which includes the reversal of deferred tax liabilities related to depreciation, during the periods in which these temporary differences become deductible. As of March 31, 2013, the Company believes that all of the deferred tax assets will be utilized and therefore has not recorded a valuation allowance.

The Company has a net operating loss carryforward ("NOL") of approximately $2.4 million for state income tax reporting purposes due to the losses sustained in various states in 2011 and 2012. The Company believes it will be able to utilize these NOL's against future income, due to expiration dates well into the future, and therefore no valuation allowance has been established. For federal tax reporting purposes, the Company carried all of its 2011 NOL back to 2009 and 2010 and received approximately $13.1 million in cash against these tax years in 2012. Part of the loss generated in 2012 was carried back to 2010, and the Company's income tax receivable reflects this estimate. Approximately $4.8 million remains as a tax carryforward, which the Company believes it will be able to utilize before expiration.

The Company does not believe that its tax positions will significantly change due to any settlement and/or expiration of statutes of limitations prior to March 31, 2014.

Earnings Per Share [Abstract]

Earnings Per Share

(Loss) Earnings Per Share

Basic (loss) earnings per share are based on the weighted average number of common shares outstanding during each period. Diluted earnings per share are based on the weighted average number of common shares outstanding and the effect of all dilutive common stock equivalents during each period. 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 months ended March 31, 2013 and 2012, no potential common stock equivalents were included as the effect of such would be anti-dilutive.

The following table reconciles the denominators used in the computations of both basic and diluted loss per share:

Stock-Based Compensation

The Company's stock incentive plan, known as the 2011 Long Term Incentive Plan, or the "2011 LTIP", was approved by shareholders in May 2011 and is administered by the Compensation Committee of the Company’s Board of Directors. The 2011 LTIP authorized 3,000,000 shares to be issued under this plan. In general, the 2011 LTIP provides for grants of restricted stock and stock options to be issued with a per-share price equal to the fair market value of a share of common stock on the date of grant.  Option terms are specified at each grant date, but are generally are 10 years from the date of issuance.  Options generally vest over a three to five year period.  

In the three months ended March 31, 2013 and 2012 , compensation expense related to stock based awards outstanding was $582,000 and $774,000, respectively. In the first quarter of 2012, the Company granted options to purchase 262,051 shares of common stock, with a fair value of $4.08 per share. No equity awards of stock or options were granted in the first quarter of 2013.

In the three months ended March 31, 2013, 33,966 options were exercised, generating proceeds to the Company of approximately $206,000. In the three months ended March 31, 2012, the Company received proceeds of approximately $13,000 upon the exercise of 2,226 options.

At March 31, 2013, total unrecognized compensation expense related to unvested stock and options was approximately $4.6 million, which is expected to be recognized over a period of 2.73 years.

Fair Value Disclosures [Abstract]

Fair Value

Fair Value

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, we believe that the carrying value of our accounts receivables, other current assets, accounts payables and other current liabilities approximate their fair values. We have a note receivable in the amount of $46,000, for which we believe that the carrying value approximates its fair value, and which bears interest at 10%. In addition, we have a long-term receivable in the amount of $1.4 million, which we believe that the carrying value of this receivable approximates its fair value.

The fair value of the Company’s reporting units (as needed for purposes of determining indications of impairment to the carrying value of goodwill) is determined using a weighted average of valuations based on market multiples, discounted cash flows, and consideration of our market capitalization.  In 2012, we acquired the assets of West Construction, which requires the fair value of the earnout liability to be re-assessed on a not less than quarterly basis. In the first quarter of 2013, the Company performed this re-assessment and did not change the fair value of its liability of $271,000.

The fair value of the Company's debt at March 31, 2013 and December 31, 2012 approximated its carrying value of $9.7 million and $12.6 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 Level 2 in the fair value hierarchy.

Long-term Debt and Line of Credit

Debt Disclosure [Abstract]

Long-term Debt and Line of Credit

Long-term Debt and Line of Credit

The Company has a credit agreement (the "Credit Agreement") with Wells Fargo Bank, National Association, as administrative agent, and Wells Fargo Securities, LLC.

The Credit Agreement, as amended from time to time, provides for borrowings under a revolving line of credit and swingline loans, an accordian, and a term loan (together, the “Credit Facility”). The Credit Facility is guaranteed by the subsidiaries of the Company, secured by the assets of the Company, including stock held in its subsidiaries, and may be used to finance working capital, repay indebtedness, fund acquisitions, and for other general corporate purposes. Interest is computed based on the designation of the loans, and bear interest at either a prime-based interest rate or a LIBOR-based interest rate.  Principal balances drawn under the Credit Facility may be prepaid at any time, in whole or in part, without premium or penalty.  Amounts repaid under the revolving line of credit may be re-borrowed. All of the components of the Credit Facility mature on June 30, 2013. On April 30, 2013, the Company extended the maturity of its Credit Facility to June 30, 2014.

Provisions of the revolving line of credit and accordian

The Company has a maximum borrowing availability under the revolving line of credit and swingline loans (as defined in the Credit Agreement) of $35 million, with a $20 million sublimit for the issuance of letters of credit. An additional $25 million is available subject to the Lender's discretion. 

Revolving loans may be designated as prime rate based loans (“ABR Loans”) or Eurodollar Loans, at the Company’s request, and may be made in an integral multiple of $500,000, in the case of an ABR Loan, or $1 million in the case of a Eurodollar Loan.   Swingline loans may only be designated as ABR Loans, and may be made in amounts equal to integral multiples of $100,000.  The Company may convert, change or modify such designations from time to time.  

Borrowings are subject to a borrowing base, which is calculated as the sum of 80% of eligible accounts receivable, plus 90% of adjusted cash balances, as defined in the Credit Agreement. At March 31, 2013, our borrowing base reflected no limitation in borrowing availability.

At March 31, 2013, no amounts were outstanding under the revolver. Outstanding letters of credit, which totaled $742,000 at March 31, 2013, reduced our maximum borrowing availability to approximately $34.3 million.

Provisions of the term loan

At March 31, 2013, the term loan component of the Credit Facility totaled $9.7 million and is secured by specific dredge assets of the Company. Principal payments on the term loan, in the amount of $389,000, are due quarterly.

Financial covenants

Restrictive financial covenants under the Credit Facility include:

• A Tangible Net Worth covenant, with the minimum Tangible Net Worth requirement of a base amount of $180 million as of June 30, 2012, plus 50% of accumulated consolidated quarterly net income (if positive), plus 75% of all issuances of equity interests by Borrower during that quarter;

• A Profitability Covenant such that the Company shall not sustain a consolidated net loss for two consecutive fiscal quarters, commencing with the quarter ending September 30, 2012.

In addition, the Credit Facility contains events of default that are usual and customary for similar transactions, including non-payment of principal, interest or fees; inaccuracy of representations and warranties; violation of covenants; bankruptcy and insolvency events; and events constituting a change of control.

The Company is subject to a commitment fee, at a current rate of 0.25% of the unused portion of the maximum available to borrow under the Credit Facility. The commitment fee is payable quarterly in arrears.  

Interest at March 31, 2013, was based on a LIBOR-option interest rate of 2.75%. For the year ended December 31, 2012, the weighted average interest rate was 2.40%.

At March 31, 2013, the Company was in compliance with its financial covenants and expects to be in compliance in 2013.

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