The Company and Basis of Presentation	'
	1. The Company and Basis of Presentation
	Willbros Group, Inc., a Delaware corporation, and its subsidiaries (the “Company,” “Willbros” or “WGI”), is a specialty energy infrastructure contractor serving the oil, gas, refinery, petrochemical and power industries. The Company’s offerings include engineering, procurement and construction (either individually or as an integrated “EPC” service offering), turnarounds, maintenance, facilities development and operations services. The Company’s principal markets for continuing operations are the United States and Canada. The Company obtains its work through competitive bidding and through negotiations with prospective clients. Contract values range from several thousand dollars to several hundred million dollars and contract durations range from a few weeks to more than two years.
	The accompanying Condensed Consolidated Balance Sheet as of December 31, 2013, which has been derived from audited consolidated financial statements, and the unaudited Condensed Consolidated Financial Statements as of March 31, 2014 and 2013, have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Accordingly, certain information and note disclosures normally included in annual financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) have been condensed or omitted pursuant to those rules and regulations. However, the Company believes the presentations and disclosures herein are adequate to make the information not misleading. These unaudited Condensed Consolidated Financial Statements should be read in conjunction with the Company’s December 31, 2013 audited Consolidated Financial Statements and notes thereto contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2013.
	In the opinion of management, the unaudited Condensed Consolidated Financial Statements reflect all adjustments necessary to fairly state the financial position as of March 31, 2014, and the results of operations and cash flows of the Company for all interim periods presented. The results of operations and cash flows for the three months ended March 31, 2014 are not necessarily indicative of the operating results and cash flows to be achieved for the full year.
	The Condensed Consolidated Financial Statements include certain estimates and assumptions made by management. These estimates and assumptions relate to the reported amounts of assets and liabilities at the dates of the Condensed Consolidated Financial Statements and the reported amounts of revenue and expense during those periods. Significant items subject to such estimates and assumptions include the carrying amount of property, plant and equipment, and parts and supplies inventories; quantification of amounts recorded for contingencies, tax accruals and certain other accrued liabilities; valuation allowances for accounts receivable and deferred income tax assets; and revenue recognition under the percentage-of-completion method of accounting, including estimates of progress toward completion and estimates of gross profit or loss accrual on contracts in progress. The Company bases its estimates on historical experience and other assumptions that it believes to be relevant under the circumstances. Actual results could differ from those estimates.
	Out-of-Period Adjustment – The Company recorded an out-of-period adjustment during the three months ended March 31, 2014 to correct an error in the state tax provision. The net impact of the adjustment was an increase to net income from continuing operations and a decrease to net loss of $0.5 million for the three months ended March 31, 2014. The Company does not believe the adjustment is material, individually or in the aggregate, to its unaudited Condensed Consolidated Financial Statements for the three months ended March 31, 2014, nor does it believe such items are material to any of its previously issued annual or quarterly financial statements, or its expected 2014 annual financial statements.

Accounting Changes And Error Corrections [Abstract]	'
New Accounting Pronouncements	'
	2. New Accounting Pronouncements
	In March 2013, the FASB amended the accounting standard related to a parent company’s accounting for the foreign cumulative translation adjustment upon derecognition of certain subsidiaries or groups of assets within a foreign entity or of an investment in a foreign entity. Under this standard, a parent entity who ceases to have a controlling interest in a subsidiary that is a business within a foreign entity should only release the cumulative translation adjustment into net income if the loss of controlling interest represents complete, or substantially complete, liquidation of the foreign entity in which the subsidiary, or asset group, had resided. This standard is effective for interim and annual periods beginning on or after December 15, 2013 and would affect the Company’s condensed consolidated financial statements if it disposes of a foreign entity.
	In July 2013, the FASB amended the accounting standard related to income taxes to eliminate a diversity in practice for the presentation of unrecognized tax benefits when net operating loss carryforwards, similar tax losses or tax credit carryforwards exist. The amendment requires that the unrecognized tax benefit be presented as a reduction of the deferred tax assets associated with the carryforwards except in certain circumstances when it would be reflected as a liability. The adoption of this revision is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. The adoption of this amendment did not have a material impact on the Company’s condensed consolidated financial statements.
	In April 2014, the FASB issued authoritative guidance to change the criteria for reporting discontinued operations. Under the new guidance, only disposals representing a strategic shift in a company's operations and financial results should be reported as discontinued operations, with expanded disclosures. In addition, disclosure of the pre-tax income attributable to a disposal of a significant part of an organization that does not qualify as a discontinued operation is required. This standard is effective for interim and annual periods beginning on or after December 15, 2014 and the Company is currently assessing the impact, if any, the guidance will have on its condensed consolidated financial statements.

	3. Contracts in Progress
	Contract cost and recognized income not yet billed on uncompleted contracts arise when recorded revenues for a contract exceed the amounts billed under the terms of the contracts. Contract billings in excess of cost and recognized income arise when billed amounts exceed revenues recorded. Amounts are billable to customers upon various measures of performance, including achievement of certain milestones, completion of specified units or completion of the contract. Also included in contract cost and recognized income not yet billed on uncompleted contracts are amounts the Company seeks to collect from customers for change orders approved in scope but not for price associated with that scope change (unapproved change orders). Revenue for these amounts is recorded equal to the lesser of the expected revenue or cost incurred when realization of price approval is probable. Estimating revenues from unapproved change orders involves the use of estimates, and it is reasonably possible that revisions to the estimated recoverable amounts of recorded unapproved change orders may be made in the near-term. If the Company does not successfully resolve these matters, a reduction in revenues may be required to amounts that have been previously recorded.
	Contract cost and recognized income not yet billed and related amounts billed as of March 31, 2014 and December 31, 2013 was as follows (in thousands):
		March 31,			December 31,
		2014			2013

	Contract billings in excess of cost and recognized income		(33,019	)		(25,933	)
		$	65,569		$	31,498
	Contract cost and recognized income not yet billed includes $4.9 million and $5.1 million at March 31, 2014 and December 31, 2013, respectively, on completed contracts.
	The balances billed but not paid by customers pursuant to retainage provisions in certain contracts will be due upon completion of the contracts and acceptance by the customer. Based on the Company’s experience with similar contracts in recent years, the majority of the retention balances at each balance sheet date will be collected within the next twelve months. Retainage balances at March 31, 2014 and December 31, 2013, were approximately $45.3 million and $39.1 million, respectively, and are included in accounts receivable.

	2013 Credit Facilities
	On August 7, 2013 the Company entered into a five-year $150.0 million asset based senior revolving credit facility maturing on August 7, 2018 with Bank of America, N.A. serving as sole administrative agent for the lenders thereunder, collateral agent, issuing bank and swingline lender (the “ABL Credit Facility”), and a six-year $250.0 million term loan facility maturing on August 7, 2019 with JP Morgan Chase Bank, N.A. serving as a sole administrative agent for the lenders thereunder (the “2013 Term Loan Facility” and, together with the ABL Credit Facility, the “2013 Credit Facilities”).
	ABL Credit Facility
	The initial aggregate amount of commitments for the ABL Credit Facility is comprised of $125.0 million for the U.S. facility (the “U.S. Facility”) and $25.0 million for the Canadian facility (the “Canadian Facility”). The ABL Credit Facility includes a sublimit of $100.0 million for letters of credit and an accordion feature permitting the borrowers, under certain conditions, to increase the aggregate amount by an incremental $75.0 million, with additional commitments from existing lenders or new commitments from lenders reasonably acceptable to the administrative agent. The borrowers under the U.S. Facility consist of all of the Company’s U.S. operating subsidiaries with assets included in the borrowing base and the U.S. Facility is guaranteed by Willbros Group, Inc. and its material U.S. subsidiaries, other than excluded subsidiaries. The borrower under the Canadian Facility is Willbros Construction Services (Canada) LP and the Canadian Facility is guaranteed by Willbros Group, Inc. and all of its material U.S. and Canadian subsidiaries, other than excluded subsidiaries.
	Advances under the U.S. and Canadian Facility are limited to a borrowing base consisting of the sum of 85 percent of the value of “eligible accounts” and 60 percent of the value of “eligible unbilled accounts” less applicable reserves, which the administrative agent may establish from time to time in its permitted discretion. Eligible unbilled accounts may not exceed $50.0 million in the aggregate. Advances in U.S. dollars will initially bear interest at a rate equal to LIBOR plus 250 basis points or the U.S. or Canadian base rate plus 150 basis points. Advances in Canadian dollars will initially bear interest at the Bankers Acceptance (“BA”) Equivalent Rate plus 250 basis points or the Canadian prime rate plus 150 basis points.
	The interest rate margins will be adjusted each quarter based on the Company’s fixed charge coverage ratio as of the end of the previous quarter as follows:
	Fixed Charge Coverage Ratio		U.S. Base Rate, Canadian			LIBOR Loans, BA Rate Loans and
			Base Rate and Canadian			Letter of Credit Fees
			Prime Rate Loans
	>1.25 to 1			1.25	%		2.25	%
	£1.25 to 1 and 1.15 to 1			1.5	%		2.5	%
	£1.15 to 1			1.75	%		2.75	%
	The borrowers will also pay an unused line fee on each of the U.S. and Canadian Facilities equal to 50 basis points when usage under the applicable facility during the preceding calendar month is less than 50 percent of the commitments or 37.5 basis points when usage under the applicable facility equals or exceeds 50 percent of the commitments for such period. With respect to the letters of credit, the borrowers will pay a letter of credit fee equal to the applicable LIBOR margin, shown in the table above, on all letters of credit and a 0.125 percent fronting fee to the issuing bank, in each case, payable monthly in arrears.
	Obligations under the ABL Credit Facility are secured by a first priority security interest in the borrowers’ and guarantors’ accounts receivable, deposit accounts and similar assets (the “ABL Priority Collateral”) and a second priority security interest in the borrowers’ and guarantors’ equipment, inventory, subsidiary capital stock and intellectual property, which is subject to the first priority security interest of the collateral agent for the 2013 Term Loan Facility (the “Term Loan Priority Collateral”).
	2013 Term Loan Facility
	The 2013 Term Loan Facility provides for a $250.0 million term loan, which the Company drew in full on the effective date of the credit agreement for the 2013 Term Loan Facility. Term loans were issued at a discount such that the funded portion was equal to 96.5 percent of the principal amount of the term loans. The borrower under the Term Loan Facility is Willbros Group, Inc. with all of its obligations guaranteed by its material U.S. subsidiaries, other than excluded subsidiaries. The 2013 Credit Facilities permit the Company, under certain conditions, to add one or more incremental term loans to the 2013 Term Loan Facility in an aggregate principal amount up to $50.0 million.
	The term loans are repayable in equal quarterly installments in an aggregate amount equal to 0.25 percent of the original amount of the 2013 Term Loan Facility. The balance of the terms loan are repayable on August 7, 2019. The Company is permitted to make optional prepayments at any time, subject to a variable prepayment premium if the prepayment is made prior to August 6, 2016. Mandatory prepayments of term loans are required from (i) 100 percent of the proceeds of the sale of assets constituting Term Loan Priority Collateral, subject to reinvestment provisions and certain exceptions and thresholds, (ii) 100 percent of the net cash proceeds from issuances of debt by the Company and its subsidiaries, other than permitted indebtedness and (iii) 75 percent (with step-downs to 50 percent and 0 percent based on a leverage ratio) of annual “excess cash flow” provided that any voluntary prepayments of term loans will be credited against excess cash flow obligations. Mandatory prepayments of excess cash flow are payable within five business days after annual financial statements are delivered to the administrative agent beginning with the fiscal year ending December 31, 2014.
	The term loans will bear interest at the Adjusted Base Rate (“ABR”) plus an applicable margin, or the “Eurodollar Rate” plus an applicable margin. The ABR is the highest of (i) the rate announced by JPMorgan Chase Bank, N.A. as its prime rate, (ii) the federal funds rate plus 0.5 percent, (iii) the Eurodollar Rate applicable for a period of one month plus 1.0 percent and (iv) 2.25 percent. The Eurodollar Rate is the rate for Eurodollar deposits for a period equal to one, two, three or six months, as selected by the Company. The applicable margin for ABR loans is 8.75 percent, and the applicable margin for Eurodollar loans is 9.75 percent.
	Obligations under the 2013 Term Loan Facility are secured by a first priority security interest in the Term Loan Priority Collateral and a second priority security interest in the ABL Priority Collateral.
	The table below sets forth the primary financial covenants included in the 2013 Credit Facilities and the calculation with respect to these covenants at March 31, 2014:
			Covenants			Actual Ratios at
			Requirements			March 31, 2014
	Maximum Total Leverage Ratio(1) under the 2013 Term Loan Facility (the ratio of Consolidated Debt to Consolidated EBITDA as defined in the credit agreement for the 2013 Term Loan Facility) should be equal to or less than:			3.50 to 1			2.38
	Minimum Interest Coverage Ratio under the 2013 Term Loan Facility (the ratio of Consolidated EBITDA to Consolidated Interest Expense as defined in the credit agreement for the 2013 Term Loan Facility) should be equal to or greater than:			3.50 to 1			3.92
	Minimum Fixed Charge Coverage Ratio(2) under the ABL Credit Facility (the ratio of Consolidated EBITDA less Capital Expenditures and cash income taxes to Consolidated Interest Expense, Restricted Payments made in cash and scheduled cash principal payments made on borrowed money as defined in the credit agreement for the ABL Credit Facility) should be equal to or greater than:			1.15 to 1			N/A
	(1)	The Maximum Total Leverage Ratio decreases to 3.00 as of June 30, 2014 and 2.75 as of March 31, 2015.
	(2)	The Minimum Fixed Charge Coverage Ratio is applicable only if excess availability under the ABL Credit Facility is less than the greater of 15 percent of the commitments or $22.5 million. In addition, prepayments of indebtedness under the 2013 Term Loan Facility are permitted if excess availability under the ABL Credit Facility exceeds the greater of 20 percent of the commitments and $30.0 million and the borrowers and guarantors are in compliance with the Minimum Fixed Charge Coverage Ratio on a pro forma basis immediately prior to and giving effect to the prepayment. Prepayments of indebtedness under the 2013 Term Loan Facility are permitted without restriction to the extent such prepayments are from the proceeds of dispositions of the Term Loan Priority Collateral.
	Depending on its financial performance, the Company may be required to request amendments, or waivers for the primary covenants, dispose of assets, reduce overhead, or obtain refinancing in future periods. There can be no assurance that the Company will be able to obtain amendments or waivers, complete asset sales, reduce sufficient amounts of overhead or negotiate agreeable refinancing terms should it become needed.
	The 2013 Credit Facilities also include customary representations and warranties and affirmative and negative covenants, including:
		•		limitations on liens and indebtedness;
		•		limitations on dividends and other payments in respect of capital stock;
		•		limitations on capital expenditures; and
		•		limitations on modifications of the documentation of the 2013 Credit Facilities.
	A default under the 2013 Credit Facilities may be triggered by events such as a failure to comply with financial covenants or other covenants under the 2013 Credit Facilities, a failure to make payments when due under the 2013 Credit Facilities, a failure to make payments when due in respect of, or a failure to perform obligations relating to, debt obligations in excess of $15.0 million, a change of control of the Company and certain insolvency proceedings. A default under the ABL Credit Facility would permit the lenders to terminate their commitment to make cash advances or issue letters of credit, require the immediate repayment of any outstanding cash advances with interest and require the cash collateralization of outstanding letter of credit obligations. A default under the 2013 Term Loan Facility would permit the lenders to require immediate repayment of all principal, interest, fees and other amounts payable thereunder.
	As of March 31, 2014, the Company was in compliance with all covenants under the 2013 Credit Facilities.
	The Company’s primary sources of capital are its cash on hand, operating cash flows and borrowings under the ABL Credit Facility. As of March 31, 2014, the Company had no outstanding revolver borrowings and $72.9 million in outstanding letters of credit. The Company’s borrowing base in effect at March 31, 2014 allowed a maximum borrowing, including outstanding letters of credit, of approximately $143.7 million. The Company’s unused availability under the ABL Credit Facility at March 31, 2014 was $70.8 million. If the Company’s unused availability under the ABL Credit Facility is less than the greater of (i) 15 percent of the revolving commitments or $22.5 million for five consecutive days, or (ii) 12.5 percent of the revolving commitments or $18.8 million at any time, or upon the occurrence of certain events of default under the ABL Credit Facility, the Company is subject to increased reporting requirements, the administrative agent shall have exclusive control over any deposit account, the Company will not have any right of access to, or withdrawal from, any deposit account, or any right to direct the disposition of funds in any deposit account, and amounts in any deposit account will be applied to reduce the outstanding amounts under the ABL Credit Facility.
	Fair Value of Debt
	The estimated fair value of the Company’s debt instruments as of March 31, 2014 and December 31, 2013 was as follows (in thousands):
			March 31,			December 31,
			2014			2013
	2013 Term Loan Facility		$	249,432		$	252,372
	Revolver borrowings under the 2013 ABL Credit Facility			—			18,953
	Capital lease obligations			2,010			2,278
	Other obligations			13,614			14,908
	Total fair value of debt instruments		$	265,056		$	288,511
	The 2013 Term Loan Facility, revolver borrowings under the 2013 ABL Credit Facility, capital lease obligations and other obligations are classified within Level 2 of the fair value hierarchy. The fair value of the 2013 Term Loan Facility has been estimated using discounted cash flow analyses based on the Company’s incremental borrowing rate for similar borrowing arrangements. A significant increase or decrease in the inputs could result in a directionally opposite change in the fair value of the 2013 Term Loan Facility.

	6. Income Taxes
	The effective tax rate on continuing operations was 99.7 percent and a negative 28.97 percent for the three months ended March 31, 2014 and March 31, 2013, respectively. Tax benefit for discrete items for the three months ended March 31, 2014 was $0.2 million, which is primarily related to interest on uncertain tax positions and for Texas Margins Tax refund. The Company has not recorded the benefit of current year losses in the U.S. As of March 31, 2014, U.S. federal and state deferred tax assets continue to be covered by valuation allowances. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income. The Company considers the impacts of reversing taxable temporary differences, future forecasted income and available tax planning strategies, when forecasting future taxable income and in evaluating whether deferred tax assets are more likely than not to be realized.
	In April 2011, the Company discontinued its strategy of reinvesting foreign earnings in foreign operations. This change in strategy continues through the first quarter of 2014. The Company does not anticipate recording tax expense related to future repatriations of foreign earnings in the U.S.
	The Company expects that the statute of limitations will expire on an uncertain tax position within the next twelve months. Assuming that the statute of limitations expires, the Company would release reserves in the amount of $1.3 million.

	Basic income (loss) per share is computed by dividing net income (loss) by the weighted average number of common shares outstanding for the period. Diluted income (loss) per share is based on the weighted average number of shares outstanding during each period and the assumed exercise of potentially dilutive stock options and vesting of RSUs less the number of treasury shares assumed to be purchased from the proceeds using the average market price of the Company’s stock for each of the periods presented.

	The Company’s segments are comprised of strategic businesses that are defined by the industries or geographic regions they serve. Each is managed as an operation with well-established strategic directions and performance requirements.
	Management evaluates the performance of each operating segment based on operating income. To support the segments, the Company has a focused corporate operation led by the executive management team, which, in addition to oversight and leadership, provides general, administrative and financing functions for the organization. The costs to provide these services are allocated, as are certain other corporate costs, to the four operating segments.

	Contingencies
	Central Maine Power
	On January 20, 2014, the Company settled a lawsuit against Central Maine Power Company (“CMP”) in connection with an existing project to install transmission lines and perform construction services for CMP, for the project generally known as the Transmission Line Construction of the Southern Loop and Southern Connector portion of the Maine Power Reliability Program (the “MPRP Project”). Under terms of the settlement, CMP made a payment to the Company in the first quarter of 2014 of $20.1 million, which consisted of $17.0 million in settlement proceeds and $3.1 million as an early payment of retention. The impact on the operating results of the settlement was recognized in the fourth quarter of 2013 and had no impact on the operating results of the first quarter of 2014. In addition, CMP extended the schedule and provided other relief on the remainder of the MPRP Project. The Company continues to perform the MPRP Project which has an expected completion date in the third quarter of 2014.
	Other
	In addition to the matters discussed above and in Note 12 – Discontinued Operations, the Company is party to a number of other legal proceedings. Management believes that the nature and number of these proceedings are typical for a firm of similar size engaged in a similar type of business and that none of these proceedings is material to the Company’s condensed consolidated results of operations, financial position or cash flows.
	Commitments
	From time to time, the Company enters into commercial commitments, usually in the form of commercial and standby letters of credit, surety bonds and financial guarantees. Contracts with the Company’s customers may require the Company to secure letters of credit or surety bonds with regard to the Company’s performance of contracted services. In such cases, the commitments can be called upon in the event of failure to perform contracted services. Likewise, contracts may allow the Company to issue letters of credit or surety bonds in lieu of contract retention provisions, where the client withholds a percentage of the contract value until project completion or expiration of a warranty period. Retention commitments can be called upon in the event of warranty or project completion issues, as prescribed in the contracts. At March 31, 2014, the Company had approximately $72.9 million of outstanding letters of credit, all of which related to continuing operations. This amount represents the maximum amount of payments the Company could be required to make if these letters of credit are drawn upon. Additionally, the Company issues surety bonds customarily required by commercial terms on construction projects. At March 31, 2014, the Company had bonds outstanding, primarily performance bonds, with a face value at $643.4 million related to continuing operations. This amount represents the bond penalty amount of future payments the Company could be required to make if the Company fails to perform its obligations under such contracts. The performance bonds do not have a stated expiration date; rather, each is released when the contract is accepted by the owner. The Company’s maximum exposure as it relates to the value of the bonds outstanding is lowered on each bonded project as the cost to complete is reduced. As of March 31, 2014, no liability has been recognized for letters of credit or surety bonds.

11. Fair Value Measurements

The FASB’s standard on fair value measurements defines fair value as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required or permitted to be recorded at fair value, the Company considers the principal or most advantageous market in which it would transact and considers assumptions that market participants would use when pricing the asset or liability, such as inherent risk, transfer restrictions, and risk of nonperformance.

Fair Value Hierarchy

The FASB’s standard on fair value measurements establishes a fair value hierarchy that requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. A financial instrument’s categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. This standard establishes three levels of inputs that may be used to measure fair value:

Level 1 –

Quoted prices in active markets for identical assets or liabilities.

Level 2 –

Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities.

Level 3 –

Unobservable inputs to the valuation methodology that are significant to the measurement of fair value of assets or liabilities.

There were no transfers between levels during the three months ended March 31, 2014.

The Company’s financial instruments consist of cash and cash equivalents, accounts receivable, accounts payable, notes payable, long-term debt and interest rate contracts. The fair value estimates of the Company’s financial instruments have been determined using available market information and appropriate valuation methodologies and approximates carrying value.

Financial Instruments Measured at Fair Value on a Recurring Basis

The Company measures certain financial instruments at fair value on a recurring basis. The fair value of these financial instruments (in thousands) was determined using the following inputs as of March 31, 2014 and December 31, 2013:

Hedging Arrangements

The Company attempts to negotiate contracts that provide for payment in U.S. dollars, but it may be required to take all or a portion of payment under a contract in another currency. To mitigate non-U.S. currency exchange risk, the Company seeks to match anticipated non-U.S. currency revenue with expenses in the same currency whenever possible. To the extent it is unable to match non-U.S. currency revenue with expenses in the same currency, the Company may use forward contracts, options or other common hedging techniques in the same non-U.S. currencies. The Company had no derivative financial instruments to hedge currency risk at March 31, 2014 or December 31, 2013.

Interest Rate Swaps

The Company is subject to hedging arrangements to fix or otherwise limit the interest cost of its variable interest rate borrowings. The Company is subject to interest rate risk on its debt and investment of cash and cash equivalents arising in the normal course of business. The Company does not engage in speculative trading strategies.

In August 2013, the Company entered into an interest rate swap agreement for a notional amount of $124.1 million to hedge changes in the variable rate interest expense on $124.1 million of its existing or replacement LIBOR indexed debt. Under the swap agreement, which is effective June 30, 2014 through August 7, 2019, the Company receives interest at either one-month LIBOR or 1.25 percent (whichever is greater) and pays interest at a fixed rate of 2.84 percent. The swap is designated and qualifies as a cash flow hedging instrument with the effective portion of the swap’s change in fair value recorded in Other Comprehensive Income (“OCI”). The swap is highly effective in offsetting changes in interest expense and no hedge ineffectiveness has been recorded in the Condensed Consolidated Statements of Operations. Amounts in OCI will be reclassified to interest expense when the hedged interest payments on the underlying debt are recognized.

In September 2010, the Company entered into two interest rate swap agreements for a total notional amount of $150.0 million to hedge changes in the variable rate interest expense on $150.0 million of its then existing or replacement LIBOR indexed debt. Under each swap agreement, the Company was to receive interest at either three-month LIBOR or 2 percent (whichever was greater) and pay interest at a fixed rate of 2.68 percent through June 30, 2014. Through August 7, 2013, the swap agreements were designated and qualified as cash flow hedging instruments, with the effective portion of the swaps’ change in fair value recorded in OCI. Amounts in OCI were reclassified to interest expense when the hedged interest payments on the underlying debt are recognized during the period when the swaps were designated as cash flow hedges. Through August 7, 2013, the swaps were highly effective hedges, and only an immaterial amount of hedge ineffectiveness was recorded in the Consolidated Statements of Operations. On August 7, 2013, the swaps were de-designated due to the refinancing of the underlying debt, which decreased the interest rate floor from 2 percent to 1.25 percent. In

addition, on August 7, 2013, each swap agreement was transferred to another party through a novation transaction, which increased the Company’s interest rate to 2.70 percent through June 30, 2014. Changes in the value of the swaps that remain open are reported in earnings and were immaterial for the three months ended March 31, 2014.

The carrying amount and fair value of these swap agreements are equivalent since the Company accounts for these instruments at fair value. The values, as identified below (in thousands), are derived from pricing models using inputs based upon market information, including contractual terms, market prices and yield curves. The inputs to the valuation pricing models are observable in the market, and as such are generally classified as Level 2 in the fair value hierarchy. For validation purposes, the swap valuations are periodically compared to those produced by swap counterparties. Amounts of OCI relating to the interest rate swaps expected to be recognized in interest expense in the coming twelve months totaled $1.7 million.

	12. Discontinued Operations
	Asset Disposals
	Hawkeye
	In the fourth quarter of 2013, the Company sold certain assets comprising the Hawkeye business to Elecnor Hawkeye, LLC, a subsidiary of Elecnor, Inc. (“Elecnor”). In connection with the sale, the Company recorded total consideration of $27.7 million, subject to a post-closing working capital adjustment. At the closing, Elecnor delivered two letters of credit, one to the Company for $16.2 million and the other to the escrow agent for $8.0 million. The Company recognized a net loss on sale in the fourth quarter of 2013 of $2.7 million and the disposition had no impact on the operating results in the first quarter of 2014.
	In the first quarter of 2014, the Company received $21.2 million in cash consisting of full payment against the $16.2 million letter of credit and $5.0 million of the $8.0 million in escrow. The Company expects to receive the remaining $6.5 million in proceeds, once the post-closing working capital adjustment is finalized.
	Former Nigeria-Based Operations
	Litigation and Settlement
	On March 29, 2012, the Company and Willbros Global Holdings, Inc., formerly known as Willbros Group, Inc., a Panama corporation (“WGHI”), which is now a subsidiary of the Company, entered into a settlement agreement (the “Settlement Agreement”) with WAPCo to settle a lawsuit filed against WGHI by WAPCo in 2010 under English law in the London High Court in which WAPCo was seeking $273.7 million plus costs and interest. The lawsuit was based upon a parent company guarantee issued by WGHI to WAPCo in connection with a Nigerian project undertaken by a WGHI subsidiary that was later sold to a third party. WAPCo alleged that the third party defaulted in the performance of the project and thereafter brought the lawsuit against WGHI under the parent company guarantee for its claimed losses.
	The Settlement Agreement provides that WGHI must make payments to WAPCo totaling $55.5 million of which $14.0 million was paid in 2012 and $5.0 million was paid in 2013. Of the remaining $36.5 million due to WAPCo, $3.8 million is due at the end of the second quarter of 2014 and $32.7 million is due at the end of the fourth quarter of 2014.
	WGI and WGHI are jointly and severally liable for payment of the amount due to WAPCo under the Settlement Agreement. WGHI and WGI are subject to a penalty rate of interest and collection efforts in the London court in the event they fail to meet any of the payments required by the Settlement Agreement.
	The Company currently has no employees working in Nigeria and does not intend to return to Nigeria.

Accounting Changes And Error Corrections [Abstract]	'
New Accounting Pronouncements	'
	In March 2013, the FASB amended the accounting standard related to a parent company’s accounting for the foreign cumulative translation adjustment upon derecognition of certain subsidiaries or groups of assets within a foreign entity or of an investment in a foreign entity. Under this standard, a parent entity who ceases to have a controlling interest in a subsidiary that is a business within a foreign entity should only release the cumulative translation adjustment into net income if the loss of controlling interest represents complete, or substantially complete, liquidation of the foreign entity in which the subsidiary, or asset group, had resided. This standard is effective for interim and annual periods beginning on or after December 15, 2013 and would affect the Company’s condensed consolidated financial statements if it disposes of a foreign entity.
	In July 2013, the FASB amended the accounting standard related to income taxes to eliminate a diversity in practice for the presentation of unrecognized tax benefits when net operating loss carryforwards, similar tax losses or tax credit carryforwards exist. The amendment requires that the unrecognized tax benefit be presented as a reduction of the deferred tax assets associated with the carryforwards except in certain circumstances when it would be reflected as a liability. The adoption of this revision is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. The adoption of this amendment did not have a material impact on the Company’s condensed consolidated financial statements.
	In April 2014, the FASB issued authoritative guidance to change the criteria for reporting discontinued operations. Under the new guidance, only disposals representing a strategic shift in a company's operations and financial results should be reported as discontinued operations, with expanded disclosures. In addition, disclosure of the pre-tax income attributable to a disposal of a significant part of an organization that does not qualify as a discontinued operation is required. This standard is effective for interim and annual periods beginning on or after December 15, 2014 and the Company is currently assessing the impact, if any, the guidance will have on its condensed consolidated financial statements.
