Accounting Policies [Abstract]	'
Description of Company and Significant Accounting Policies	'
	Description of Company and Significant Accounting Policies
	KBR, Inc., a Delaware corporation, was formed on March 21, 2006 and is headquartered in Houston, Texas. KBR, Inc. and its wholly owned and majority-owned subsidiaries (collectively referred to herein as "KBR", "the Company", "we", "us" or "our") is a global provider of engineering, procurement, construction, construction management, technology licensing, operations and maintenance and other support services to a diverse customer base, including international and national oil and gas companies, independent refiners, petrochemical producers, fertilizer producers, regulated utilities, manufacturers, power and mining companies and domestic and foreign governments.
	Principles of consolidation
	Our condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States ("U.S. GAAP") and include the accounts of KBR and our wholly owned and majority-owned, controlled subsidiaries and variable interest entities of which we are the primary beneficiary. We account for investments over which we have significant influence but not a controlling financial interest using the equity method of accounting. See Note 7 for further discussion on our equity investments and variable interest entities. The cost method is used when we do not have the ability to exert significant influence. All material intercompany balances and transactions are eliminated in consolidation.
	Certain prior year amounts have been reclassified to conform to the current year presentation on the condensed consolidated statement of income, condensed consolidated balance sheets and the condensed consolidated statements of cash flows. For the three months ended March 31, 2014, we reclassified equity in earnings of unconsolidated affiliates from revenues to a separate component of operating income on our condensed consolidated statement of income. We reclassified the 2013 amounts to conform to our revised presentation as a component of operating income but not a component of revenues.
	We have evaluated all events and transactions occurring after the balance sheet date but before the financial statements were issued and have included the appropriate disclosures.
	Use of estimates
	The preparation of our condensed consolidated financial statements in conformity with U.S. GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period, including:
	•	project revenues, costs and profits on engineering, construction, pipe fabrication and module assembly, and government services contracts, including recognition of estimated losses on uncompleted contracts,
	•	uncollectible receivables, claims to and from clients, recoveries of costs from subcontractors, vendors and others,
	•income taxes and related valuation allowances and tax uncertainties,
	•recoverability of goodwill,
	•other intangibles and long-lived assets and related estimated lives,
	•recoverability of equity method and cost method investments,
	•valuation of pension obligations,
	•accruals for estimated liabilities and litigation outcomes,
	•consolidation of variable interest entities,
	•and valuation of stock-based compensation.
	In accordance with normal practice in the construction industry, we include in current assets and current liabilities amounts related to construction contracts realizable and payable over a period in excess of one year. Actual amounts may differ from those included in the accompanying condensed consolidated financial statements, if the underlying estimates and assumptions upon which the financial statements are based change in the future.
	Gross Profit
	Gross profit represents business segment revenue less the cost of revenue, which includes business segment overhead costs directly attributable to the business segment. See Note 2 for our discussion on Business Segment gross profit (loss).
	Accounts Receivable
	Accounts receivable are recorded at the invoiced amount based on contracted prices. Amounts collected on accounts receivable are included in net cash provided by operating activities in the condensed consolidated statements of cash flows.
	We establish an allowance for doubtful accounts based on the assessment of the clients’ willingness and ability to pay. In addition to such allowances, there are often items in dispute or being negotiated that may require us to make an estimate as to the ultimate outcome. Past due receivable balances are written off when our internal collection efforts have been unsuccessful in collecting the amounts due. See Note 4 for our discussion on accounts receivable.
	Retainage, included in accounts receivable, represents amounts withheld from billings by our clients pursuant to provisions in the contracts and may not be paid to us until the completion of specific tasks on the project and for longer periods, in some instances. Retainage may also be subject to restrictive conditions such as performance guarantees. Our retainage receivable excludes amounts withheld by the United States ("U.S.") government on certain contracts. See Note 10 for our discussion on U.S. government receivables.
	Costs and Estimated Earnings in Excess of Billings on Uncompleted Contracts, Including Claims, and Advanced Billings and Billings in Excess of Costs and Estimated Earnings on Uncompleted Contracts
	Costs and estimated earnings in excess of billings on uncompleted contracts ("CIE") represent the excess of contract costs and profits recognized to date using the percentage-of-completion method over billings to date on certain contracts. Billings in excess of costs and estimated earnings on uncompleted contracts ("BIE") represents the excess of billings to date over the amount of contract costs and profits recognized to date using the percentage-of-completion method on certain contracts. See Note 5 for our discussion on CIE and BIE.
	Unapproved change orders and claims
	When estimating the amount of total gross profit or loss on a contract, we include unapproved change orders and claims to our clients as adjustments to revenues and claims to vendors, subcontractors and others as adjustments to total estimated costs. Claims are recorded to the extent of the lesser of the amounts management expects to recover or to costs incurred and include no profit until they are finalized and approved.
	Goodwill
	Effective January 1, 2014, we reorganized four of the five reporting units in the Infrastructure, Government and Power ("IGP") business segment into three geographic-based units. This reorganization allows the IGP business segment to focus its full-scope engineering, procurement, construction and defense services to clients on a more local level. We have concluded that each of these geographic-based units will be considered a separate reporting unit for goodwill impairment testing purposes. As a result, we performed an additional impairment test on the three newly reorganized reporting units on January 1, 2014 as required by ASC 350-20, utilizing the same methodology as our annual goodwill impairment test, and no indication of impairment was identified. For more detail on our methodology and assumptions, see "Critical Accounting Policies" in our 2013 Annual Report on Form 10-K/A.
	Share-based Compensation
	Effective January 1, 2014, we changed our methodology for estimating the expected term of our option awards and we will no longer utilize the simplified method. We will measure all future stock option awards using an expected term based on KBR’s historical experience.

Segment Reporting [Abstract]	'
Business Segment Information	'
	Business Segment Information
	We provide a wide range of services and the management of our business is heavily focused on major projects within each of our reportable segments. At any given time, a relatively few number of projects and joint ventures represent a substantial part of our operations. Our reportable segments follow the same accounting policies as those described in Note 1 herein and in Note 1 to our consolidated financial statements included in our 2013 Annual Report on Form 10-K/A.
	Our business segment information has been prepared in accordance with ASC 280 - Segment Reporting. Certain of our reporting units meet the definition of operating segments contained in ASC 280 - Segment Reporting, but individually do not meet the quantitative thresholds as a reportable segment, nor do they share a majority of the aggregation criteria with another operating segment. These operating segments are reported on a combined basis as “Other” and include our Ventures and Technical Staffing Resources (formerly a part of Allstates Technical Services) as well as corporate expenses not included in the operating segments’ results.
	Reportable segment performance is evaluated by our Chief Operating Decision Maker ("CODM") using reportable segment gross profit (loss) which is defined as business segment revenue less the cost of revenue, which includes business segment overhead directly attributable to the segment, but excludes equity in earnings of unconsolidated affiliates.
	Business Reorganization
	During 2013, we reorganized our business to better serve our customers, improve our organizational efficiency and achieve future growth objectives. In order to attain these objectives, we separated our Hydrocarbons reportable segment into two separate reportable segments, Gas Monetization and Hydrocarbons, such that now we have a total of five reportable segments: Gas Monetization, Hydrocarbons, IGP, Services and Other. Each reportable segment, excluding Other, is led by a separate Segment President who reports directly to our CODM. We have revised our business segment reporting to reflect our current management approach and recast prior periods to conform to the current business segment presentation.
	The following table presents revenue, gross profit (loss), equity in earnings of unconsolidated affiliates and operating income by reporting segment.

	Changes in Estimates
	There are many factors, including, but not limited to, the availability and costs of labor, materials and equipment, and resources, productivity, and weather, that can affect the accuracy of our cost estimates, and ultimately, our future profitability. In the past, we have realized both lower and higher than expected margins and have incurred losses as a result of unforeseen changes in our project costs; however, historically, our estimates have been reasonably dependable regarding the recognition of revenue and profit on percentage of completion contracts.
	Our Services business segment recognized revisions in our estimates of losses at completion on our Canadian pipe fabrication and module assembly projects of $41 million during the three months ended March 31, 2014. As described in our Amendment No. 1 (“Form 10-K/A”) to our Form 10-K for the fiscal year ended December 31, 2013, we recognized pre-tax charges of $156 million as of December 31, 2013 related to the identification of additional estimated costs to complete our Canadian pipe fabrication and module assembly projects. The additional losses recognized on these projects during the three-months ended March 31, 2014 were a result of (i) estimated losses on a new project contracted in December 2013, (ii) significant increases in quantities on one project as a result of design and quantity changes during the quarter which are currently not considered recoverable from the customer, (iii) estimated subcontractor costs due to design changes and delays, and (iv) estimated costs associated with recent productivity results. All of these projects are in loss positions at March 31, 2014 and December 31, 2013. Our reserve for losses on uncompleted contracts included $107 million and $97 million at March 31, 2014 and December 31, 2013, respectively, for losses on these Canadian pipe fabrication and module assembly projects. Based on current contracts and work authorizations, we anticipate completion of these projects in 2015.
	During the quarter ended March 31, 2014, we recognized revisions in estimates on a liquefied natural gas ("LNG") project in Australia as a result of additional fees associated with approved man hours and other revisions in estimates which had a $21 million positive impact on the gross profit of our Gas Monetization business segment. Additionally, our Gas Monetization business segment recognized revisions in estimates on an LNG project in Algeria resulting from a favorable settlement of claims, which had a $33 million net positive impact on gross profit.
	During the quarter ended March 31, 2013, we recognized revisions in contract estimates which had a $38 million positive impact on the gross profit of our Gas Monetization business segment, as a result of revised project estimates on our LNG projects in Australia and Algeria.

Cash and Cash Equivalents [Abstract]	'
Cash and Cash Equivalents	'
	Cash and Equivalents
	We consider all highly liquid investments with an original maturity of three months or less to be cash equivalents. Cash and equivalents include cash balances held by our wholly-owned subsidiaries as well as cash held by joint ventures that we consolidate. Joint venture cash balances are limited to joint venture activities and are not available for other projects, general cash needs or distribution to us without approval of the board of directors of the respective joint ventures. We expect to use joint venture cash for project costs and distributions of earnings related to joint venture operations. However, some of the earnings distributions may be paid to other KBR entities where the cash can be used for general corporate needs.
	The components of our cash and equivalents balance are as follows:
		31-Mar-14
	Millions of dollars	International (a)		Domestic (b)		Total
	Operating cash	$	155	$	214	$	369
	Time deposits	486		35		521

	Millions of dollars	International (a)		Domestic (b)		Total
	Operating cash	$	197	$	215	$	412
	Time deposits	478		140		618
	Cash held in joint ventures	67		9		76
	Total	$	742	$	364	$	1,106
	(a)	Includes deposits held in non-U.S. operating accounts considered to be permanently reinvested outside the U.S. and for which no incremental U.S. tax has been provisioned or paid
	(b)	Includes U.S. dollar and foreign currency deposits held in operating accounts that constitute onshore cash for tax purposes but may reside either in the U.S. or in a foreign country
	Our international cash balances are primarily held in the United Kingdom ("U.K."), Australia and the Cayman Islands. We generally do not provide U.S. federal and state income taxes on the accumulated undistributed earnings of non-U.S. subsidiaries except for certain entities in Mexico and certain other joint ventures, as well as for approximately 50% of our earnings from our operations in Australia. Taxes are provided as necessary with respect to earnings that are considered not permanently reinvested. We will continue to provide for U.S. federal and state taxes on 50% of the earnings of our Australian operations as we no longer intend to permanently reinvest these amounts. In determining whether earnings would be considered permanently invested, we considered future non-U.S. cash needs such as: 1) our anticipated foreign working capital requirements, including funding of our U.K. pension plan; 2) the expected growth opportunities across all geographical markets; and 3) our plans to invest in strategic growth opportunities that may include acquisitions around the world. For all other non-U.S. subsidiaries, no U.S. taxes are provided because such earnings are intended to be reinvested indefinitely to finance foreign activities. These accumulated but undistributed foreign earnings could be subject to additional tax if remitted, or deemed remitted, as a dividend. If any portion of the unremitted earnings were ever foreseen to not be permanently reinvested outside the U.S., or if we elect to repatriate a portion of current year foreign earnings, U.S. income tax expense would be required to be recognized and that expense could be material.

	Amounts recorded in revenues on a percentage-of-completion basis at March 31,	$	50		$	149
	The decrease in changes in estimates in 2014 relates primarily to a net favorable settlement of certain claims on an Algerian LNG project partially offset by increases in estimates on a construction project in our Services business segment for which the client routinely issues scope changes which are subsequently followed with a change order. In 2014, approved change orders reflect approvals on an air quality project in North America.
	Included in our 2013 changes in estimates-at-completion are increases related to a construction project in our Services business segment for which the client routinely issues scope changes which are subsequently followed with a change order.
	The table above excludes unapproved change orders and claims related to our unconsolidated subsidiaries. Our proportionate share of unapproved change orders and claims on a percentage-of-completion basis were $79 million as of March 31, 2014 and $46 million as of March 31, 2013 related to the Ichthys LNG project joint venture.
	Liquidated damages
	Some of our engineering and construction contracts have schedule dates and performance obligations that if not met could subject us to penalties for liquidated damages. These generally relate to specified activities that must be completed by a set contractual date or by achievement of a specified level of output or throughput. Each contract defines the conditions under which a customer may make a claim for liquidated damages. However, in some instances, liquidated damages are not asserted by the customer, but the potential to do so is used in negotiating or settling claims and closing out the contract. Any accrued liquidated damages are recognized as a reduction in revenues in the condensed consolidated statements of income.
	Based upon our evaluation of our performance and other legal analysis, we have not accrued for possible liquidated damages related to several projects totaling $10 million at March 31, 2014 and December 31, 2013, respectively, (including amounts related to our proportional share of unconsolidated subsidiaries), that we could incur based upon completing the projects as currently forecasted.
	Advances
	We may receive customer advances in the normal course of business, most of which are applied to invoices usually within one to three months. In addition, we hold advances from customers to assist us in financing project activities, including subcontractor costs. As of March 31, 2014 and December 31, 2013, $44 million and $50 million, respectively, of these finance-related advances are included in BIE on our condensed consolidated balance sheets.
	Reserve for estimated losses on uncompleted contracts
	Our reserve for estimated losses on uncompleted contracts is included in "other current liabilities" on our condensed consolidated balance sheet. Our total reserve as of March 31, 2014 and December 31, 2013 is $123 million and $109 million, respectively, including $107 million and $97 million, respectively, related to our Canadian pipe fabrication and module assembly projects.

	Equity Method Investments and Variable Interest Entities
	We conduct some of our operations through joint ventures which operate through partnership, corporate, undivided interest and other business forms and are principally accounted for using the equity method of accounting. Additionally, the majority of our joint ventures are also variable interest entities which are further described under ASC 810 - Consolidations - Variable Interest Entities.
	The following table presents a rollforward of our equity in and advances to unconsolidated affiliates:

	Related Party Transactions
	We often participate in several projects as a joint venture partner in addition to providing services, which include engineering and construction management services, to the joint venture as a subcontractor. The amounts included in our revenue represent revenue from services provided directly to the joint ventures as a subcontractor. As of March 31, 2014 and 2013, our revenues included $68 million and $59 million, respectively, primarily related to services we provided to our Ichthys LNG project joint venture.
	Amounts included in our condensed consolidated balance sheets related to services we provided to our joint ventures as of March 31, 2014 and December 31, 2013 are as follows:

	EBIC Ammonia project	$	47		$	2
	Fermoy Road project	$	1		$	2
	Generally, our maximum exposure to loss is limited to our equity investment in the joint venture and any amounts payable to us for services we provided to the joint venture, reduced for any unearned revenues on the projects. On the Aspire Defence project, in addition to the maximum exposure to loss indicated in the table above, we have exposure to any losses incurred by the construction or operating joint ventures under their respective subcontract arrangements with the project company. Our exposure is, however, limited to our equity participation in these entities. The Ichthys LNG project joint venture executes a project that has a lump sum component, in addition to the maximum exposure to loss indicated in the table above, we have an exposure to losses if the project exceeds the lump sum component to the extent of our ownership percentage in the joint venture. Our maximum exposure to loss on the EBIC Ammonia project reflects our 65% ownership of the development corporation which owns 25% of the company that consolidates the ammonia plant.
	Consolidated Variable Interest Entities
	We consolidate VIEs if we determine we are the primary beneficiary of the project entity because we control the activities that most significantly impact the economic performance of the entity. The following is a summary of the significant VIEs where we are the primary beneficiary:

	Income Taxes
	Our estimated annual effective tax rate for the years 2014 and 2013 reconciled to the 35% U.S. statutory federal rate is as follows:
		2014		2013
	U.S. statutory federal rate	35	%	35	%
	Rate differentials on foreign earnings	(5.8	)%	(6.4	)%
	Taxes on unincorporated joint ventures	(4.6	)%	(2.1	)%

	Other	1.4	%	2.7	%
	Estimated annual effective tax rate	22.2	%	27.5	%
	We generally do not provide U.S. federal and state income taxes on the accumulated undistributed earnings of non-U.S. subsidiaries except for certain entities in Mexico and certain other joint ventures, as well as for approximately 50% of our earnings from our operations in Australia. See Note 3 for additional information regarding our accumulated undistributed earnings. Due to historical and forecasted losses for certain non-U.S. affiliates, we are not allowed to record a tax benefit for current period net operating losses recognized by these affiliates. As a result, our effective tax rate for the period has increased.
	The effective tax rate for the three months ended March 31, 2014 is not meaningful due to the lower income before incomes taxes, the recording of a valuation allowance on the losses recognized on our Canadian pipe fabrication and module assembly business, and discrete items. As of March 31, 2014, our total valuation allowance is $105 million, an increase of $22 million from December 31, 2013. Our effective rate for the three months ended March 31, 2013 reflected in the condensed consolidated statements of income of 23.6% is lower than our estimated annual effective rate of 27.5%, primarily due to discrete items.

	U.S. Government Matters
	We provide services to various U.S. governmental agencies, which include the United States Department of Defense (“DoD”), the Department of State and others. We may have disagreements or experience performance issues on our U.S. government contracts. When performance issues arise under any of these contracts, the government retains the right to pursue various remedies, including challenges to expenditures, suspension of payments, fines and suspensions or debarment from future business with the government.
	With the U.S. Army's withdrawal from Iraq, our work with the U.S. government in the war zone areas has ended. We have been in the process of closeout with these contracts since 2011, and we expect the closeout process to continue through at least 2018. As a result of our work in a war zone from 2002 to 2011, there are multiple claims and disputes pending between us and the government, all of which need to be resolved to close the contracts. The closeout process includes resolving objections raised by the government through a billing dispute process referred to as Form 1s and Memorandums for Record ("MFRs") and resolving results from government audits. We continue to work with the government to resolve these issues. However, for certain of these matters, we have filed claims with the Armed Services Board of Contract Appeals ("ASBCA") or the U.S. Court of Federal Claims ("COFC"). We also have matters related to ongoing litigation or investigations involving U.S. government contracts. We anticipate billing additional labor, vendor resolution and litigation costs as we resolve the open matters. At this time, we cannot determine the timing or net amounts to be collected or paid to close out these contracts.
	Form 1s
	The government has issued Form 1s questioning or objecting to costs we billed to them. We believe the amount we have invoiced the customer are in compliance with our contract terms; however, we continue to evaluate our ability to recover these amounts from our customer. A summary of our Form 1s received and amount associated with our Form 1s are as follows:
		March 31,		December 31,
	Millions of dollars	2014		2013
	Form 1s (Total claimed by the government)	$	274	$	274
	Amounts withheld by government (Included in the Form 1s amount above) (a)	137		137
	Amounts withheld from subcontractors by us	50		50
	Claims loss accruals (b)	74		74
	(a)	Recorded in "claims and accounts receivable" on our condensed consolidated balance sheets.
	(b)	Recorded as a reduction to "claims and accounts receivable" and in "other liabilities" on our condensed consolidated balance sheets. At this time, we believe the likelihood we would incur a loss related to this matter in excess of the loss accruals we have recorded is remote.
	Summarized below are some of the specific issues associated with individual Form 1s as part of the total explained above.
	Private Security. Starting in February 2007, we received a series of Form 1s from the Defense Contract Audit Agency ("DCAA") informing us of the government's intent to deny reimbursement to us under the LogCAP III contract for amounts related to the use of private security contractors ("PSCs") by KBR and a subcontractor in connection with its work for KBR providing dining facility services in Iraq between 2003 and 2006. Currently the government is challenging $56 million in billings. The government had previously paid $11 million and has withheld payments of $45 million, which as of March 31, 2014 we have recorded due from the government related to this matter in "claims and accounts receivable" on our condensed consolidated balance sheets. Additionally, we have withheld payments to subcontractors of $1 million associated with this matter. We believe the likelihood that we will incur a loss related to this matter is remote, and therefore we have not accrued any loss provisions related to this matter.
	The government has indicated that it believes our LogCAP III contract prohibited us and our subcontractors from billing amounts related to the use of PSCs. We believe that, while the LogCAP III contract obligated the Department of the Army ("Army") to provide force protection, it did not prohibit us or any of our subcontractors from using PSCs to provide force protection to KBR or subcontractor personnel. We also contend that the Army breached its obligation to provide force protection. In addition, a significant portion of our subcontracts were fixed price subcontracts awarded without obtaining certified cost or pricing data. As a result, we did not receive details of the subcontractors’ cost estimate, and it is our position that we were not legally entitled to that information. Accordingly, we believe that we are entitled to reimbursement by the Army for the amounts charged by our subcontractors, even if they incurred costs for PSCs. Therefore, we do not agree with the Army’s position that such costs are unallowable and that they were entitled to withhold payment for the billed amounts in question. We presented our claims for reimbursement to the ASBCA in late 2013 and expect a ruling in 2014.
	Containers. In June 2005, the DCAA questioned billings related to costs associated with providing containerized housing for soldiers and supporting civilian personnel in Iraq. The Defense Contract Management Agency ("DCMA") recommended that payment for the billings be withheld pending receipt of additional explanation or documentation to support the subcontract costs. The Form 1 was issued for $51 million in billings. Of this amount, the government had previously paid $25 million and has withheld payments of $26 million, which as of March 31, 2014, we have recorded in "claims and accounts receivable" on our condensed consolidated balance sheets.
	Included in "other liabilities" on our condensed consolidated balance sheets is $45 million of payments withheld from subcontractors related to pay-when-paid contractual terms. Of this amount, $15 million is due from the government and recorded in "claims and accounts receivable" on our condensed consolidated balance sheets. At this time, we believe that the likelihood we would incur a loss related to this matter in excess of the amounts we have withheld from subcontractors and the loss accruals we have recorded is remote.
	There are three related actions stemming from the DCMA's action to disallow and withhold funds. First, in April 2008 we filed a counterclaim in arbitration against our LogCAP III subcontractor, First Kuwaiti Trading Company, to recover the amounts we paid to the subcontractor for containerized housing if we should lose the contract dispute with the government over the allowability of the container claims. Second, during the first quarter of 2011 we filed a complaint before the ASBCA to contest the Form 1s and to recover the amounts withheld from us by the government. At the request of the government, that complaint was dismissed without prejudice in January 2013 so that the government could pursue its False Claims Act suit described below. We are free to re-file the complaint in the future. Third, this matter is also the subject of a separate claim filed by the Department of Justice ("DOJ") for alleged violation of the False Claims Act as discussed further below under the heading “Investigations, Qui Tams and Litigation.”
	Tamimi.
	Tamimi - Form 1. In 2006, the DCAA questioned the price reasonableness of billed costs related to dining facilities in Iraq. We responded to the DCMA that we believe our costs are reasonable. The prices obtained for these services were from our subcontractor Tamimi. The Form 1 was issued for $71 million in billings. The government had previously paid $28 million and has withheld payments of $43 million.
	At March 31, 2014, we have recorded $43 million due from the government related to these matters in "claims and accounts receivable" on our condensed consolidated balance sheets and accrued our estimate related to any probable loss in "other liabilities" on our condensed consolidated balance sheets. At this time, we believe the likelihood we would incur a loss related to this matter in excess of the loss accruals we have recorded is remote.
	In April 2012, the U.S. COFC ruled that KBR's negotiated price for certain dining facility services were not reasonable and that we were entitled to only $12 million of the amounts withheld from us by the government plus any applicable interest ($2 million). In addition, while this matter was before the court the U.S. government withheld an additional $1 million. As a result of this ruling, we recognized a pre-tax charge of $28 million as a reduction to revenue. We appealed the U.S. COFC ruling and in September 2013, a three judge panel of the Federal Circuit Court of Appeals issued its opinion upholding the ruling. We are preparing to file an application of certiorari with the U.S. Supreme Court.
	Tamimi - DOJ. In March 2011, the DOJ filed a counterclaim in the U.S. COFC alleging KBR employees accepted bribes from Tamimi in exchange for awarding a master agreement for DFAC services to Tamimi. The April 2012 ruling on the Tamimi matter discussed above dismissed the DOJ claims as lacking merit. On appeal, the DOJ's efforts to overturn the trial court ruling have been denied.
	Fly America. In 2007, the DCAA questioned costs related to our compliance with the provisions of the Fly America Act. Subject to certain exceptions, the Fly America Act requires Federal employees and others performing U.S. government-financed contracts to travel by U.S. flag air carriers. The Form 1 was issued for $6 million in billings, all of which had been previously paid by the government. No payments have been withheld by the government for this matter. At March 31, 2014, we have accrued our estimate of the cost incurred for these potentially noncompliant flights recorded in "other liabilities" on our condensed consolidated balance sheets. At this time, we believe the likelihood we would incur a loss related to this matter in excess of the loss accruals we have recorded is remote.
	There were times when we transported personnel in connection with our services for the U.S. military where we may not have been in compliance with the Fly America Act and its interpretations through the Federal Acquisition Regulations ("FAR") and the Comptroller General. In October 2011, at the request of the DCMA, we submitted an estimate of the impact of our non-compliance with the Fly America Act for 2003 and 2004. In May 2014, the Contracting Officer rendered a Contracting Officer Final Determination (“COFD”) disallowing $3 million in billings. We have entered into negotiations as we believe we have provided adequate support to demonstrate that U.S. flag air carriers were not available for certain travel.
	H-29. In the first quarter of 2011, we received a Form 1 from the DCAA disapproving certain transportation costs associated with replacing employees who were deployed in Iraq and Afghanistan for less than 179 days.  The DCAA claims these replacement costs violate the terms of the LogCAP III contract which expressly disallow certain costs associated with the contractor rotation of employees who have deployed less than 179 days including costs for transportation, lodging, meals, orientation and various forms of per diem allowances.  We disagree with the DCAA’s interpretation and application of the contract terms as it was applied to circumstances outside of our control including war risks, sickness, death, termination for cause or resignation and that such costs should be allowable. The Form 1 was issued for $27 million in billings, all of which had been previously paid by the government. No payments have been withheld by the government for this matter.
	In March 2013, we filed a notice of appeal to the ASBCA and filed our complaint in the appeal in April 2013. The government filed a motion to dismiss in April 2013 and in September 2013 that motion was denied. We and the government agreed to submit the appeal for a judgment on the pleadings. The parties submitted cross-motions and cross-reply briefs in November 2013. The ASBCA has scheduled a hearing on the pending cross-motions for judgment for June 26, 2014. At March 31, 2014, we have accrued our estimate of the potentially non-compliant cost incurred recorded in "other liabilities" on our condensed consolidated balance sheets. At this time, we do not believe we face a risk of material loss from any disallowance of these costs in excess of the loss accruals we have recorded. There is a parallel qui tam further described under the caption "Chillcott qui tam" below.
	CONCAP III. From February 2009 through September 2010, we received Form 1s from the DCAA disapproving billed costs related to work performed under our CONCAP III contract with the U.S. Navy to provide emergency construction services primarily to government facilities damaged by Hurricanes Katrina and Wilma. The Form 1 was issued for $25 million in billings. The government had previously paid $15 million and has withheld payments of $10 million.
	In February 2012, the Contracting Officer rendered a COFD disallowing $15 million of direct costs. We filed an appeal with the ASBCA in June 2012. We believe we undertook adequate and reasonable steps to ensure that proper bidding procedures were followed and the amounts billed to the government were reasonable and not in violation of the FAR.
	As of March 31, 2014, we have recorded $10 million due from the government related to these matters in "claims and accounts receivable" on our condensed consolidated balance sheets. As of March 31, 2014, we have accrued our estimate of probable loss related to an unfavorable settlement of this matter recorded in "other liabilities" on our condensed consolidated balance sheets. At this time, we believe that the likelihood we would incur a loss related to this matter in excess of the amounts we have accrued is remote.
	Other. The government has issued Form 1s for other matters questioning $38 million of billed costs. For these matters, the government previously paid $25 million and has withheld payment of $13 million, which we have recorded in "claims and accounts receivable" on our condensed consolidated balance sheets. We have accrued our estimate of probable loss in "other liabilities" on our condensed consolidated balance sheets. At this time, we believe that the likelihood we would incur a loss related to this matter in excess of the amounts we have accrued is remote.
	We have other matters in dispute with the government either in the COFC or before the ASBCA. These claims represent $12 million in claimed costs primarily associated with the pass-through of subcontractor claims associated with a termination for convenience in Iraq. We have accrued $2 million as our estimate of probable loss in "other liabilities" on our condensed consolidated balance sheets.
	Audits
	In addition to reviews being performed by the U.S. government through the Form 1 process, the negotiation, administration and settlement of our contracts, consisting primarily of DoD contracts, are subject to audit by the DCAA, which serves in an advisory role to the DCMA. The DCMA is responsible for the administration of our contracts. The scope of these audits include, among other things, the allowability, allocability and reasonableness of incurred costs, provisional approval of annual billing rates, approval of annual overhead rates, compliance with the FAR and Cost Accounting Standards (“CAS”), compliance with certain unique contract clauses and audits of certain aspects of our internal control systems. We attempt to resolve all issues identified in audit reports by working directly with the DCAA and the Administrative Contracting Officers ("ACOs").
	As a result of these audits, there are risks that what we have billed as recoverable costs may be assessed by the government to be unallowable. We believe our billings are in compliance with our contract terms. In some cases, we may not reach agreement with the DCAA or the ACOs regarding potentially unallowable costs which may result in our filing of claims in various courts such as the ASBCA or the U.S. COFC. We have accrued our estimate of potentially unallowable costs using a combination of specific estimates and our settlement rate experience with the government. As of March 31, 2014, we have accrued $44 million as our estimate of probable loss as a reduction to "claims and accounts receivable" and in "other liabilities" on our condensed consolidated balance sheets. These accrued amounts are associated with years for which we have and do not have audit reports. We have received audit reports for 2004 through 2007 and 2009. We have not yet received completed audit reports for 2008 or 2010 through 2012. Additionally, we have not reached an agreement with the government on definitive incurred cost rates after 2003.
	We only include amounts in revenue related to disputed and potentially unallowable costs when we determine it is probable that such costs will result in the collection of revenue. We generally do not recognize additional revenue for disputed or potentially unallowable costs for which revenue has been previously reduced until we reach agreement with the DCAA and/or the ACOs that such costs are allowable.
	In addition to audits of our incurred costs, the government also reviews our compliance with the cost accounting standards ("CAS") and the adequacy and compliance of our CAS disclosure statements. We are working with the government to resolve several outstanding alleged CAS non-compliance issues.
	Investigations, Qui Tams and Litigation
	The following matters relate to ongoing litigation or investigations involving U.S. government contracts.
	First Kuwaiti Trading Company arbitration. In April 2008, First Kuwaiti Trading Company ("FKTC" or "First Kuwaiti"), one of our LogCAP III subcontractors, filed for arbitration with the American Arbitration Association of all its claims under various LogCAP III subcontracts. First Kuwaiti sought damages in the amount of $134 million. After completing hearings on all of FKTC's claims, an arbitration panel awarded $16 million to FKTC for claims involving damages on lost or unreturned vehicles. In addition, we have stipulated that we owe FKTC $29 million in connection with five other subcontracts. We have an agreement with FKTC that no damages will be paid until our counterclaim is decided, but FKTC has now filed a motion with the arbitration panel to compel KBR to pay all amounts outstanding. We are contesting this motion and a hearing has been set for September 2, 2014. We believe any damages ultimately awarded to First Kuwaiti will be billable under the LogCAP III contract. Accordingly, we have accrued amounts in "accounts payable" and "other current liabilities" on our condensed consolidated balance sheets and related amounts in "claims and accounts receivable" on our condensed consolidated balance sheets for the amounts awarded to First Kuwaiti pursuant to the terms of the contract. We also have a counterclaim still pending for any funds we should have to return or refund to the government in the container litigation discussed above.
	Electrocution litigation. During 2008, a lawsuit was filed against KBR in Pittsburgh, PA, in the Allegheny County Common Pleas Court alleging that the Company was responsible for an electrical incident which resulted in the death of a soldier. This incident occurred at the Radwaniyah Palace Complex near Baghdad, Iraq. It is alleged in the suit that the electrocution incident was caused by improper electrical maintenance or other electrical work. KBR denies that its conduct was the cause of the event and denies legal responsibility. Plaintiffs are claiming unspecified damages for personal injury, death and loss of consortium by the parents. On July 13, 2012, the Court granted our motions to dismiss, concluding that the case is barred by the Political Question Doctrine and preempted by the Combatant Activities Exception to the Federal Tort Claims Act. The plaintiffs appealed to the Third Circuit Court of Appeals. In August 2013, the Third Circuit Court of Appeals issued an opinion reversing the trial court's dismissal and remanding for further discovery and legal rulings. KBR filed its motion for rehearing en banc, which was denied, and we have filed an application for writ of certiorari to the U.S. Supreme Court. Four amicus briefs have been filed in support of KBR's legal arguments. On June 16, 2014 the U.S. Supreme Court issued an order inviting the Solicitor General to file briefs in the electrocution litigation, expressing the views of the United States as to KBR's pending applications for writ of certiorari. We anticipate these briefs will not be filed until the fourth quarter of 2014. At this time, we believe the likelihood we would incur a loss related to this matter is remote. As of March 31, 2014, no amounts have been accrued.
	Burn Pit litigation. From November 2008 through March 2013, KBR was served with over 50 lawsuits in various states alleging exposure to toxic materials resulting from the operation of burn pits in Iraq or Afghanistan in connection with services provided by KBR under the LogCAP III contract. Each lawsuit has multiple named plaintiffs and seeks class certification. The lawsuits primarily allege negligence, willful and wanton conduct, battery, intentional infliction of emotional harm, personal injury and failure to warn of dangerous and toxic exposures which has resulted in alleged illnesses for contractors and soldiers living and working in the bases where the pits were operated. The plaintiffs are claiming unspecified damages. All of the pending cases were removed to Federal Court and have been consolidated for multi-district litigation treatment before the U.S. Federal District Court in Baltimore, Maryland.
	In February 2013, the Court dismissed the case against KBR, accepting all of KBR's defense claims including the Political Question Doctrine; the Combatant Activities Exception to the Federal Tort Claims Act; and Derivative Sovereign Immunity. The plaintiffs appealed to the Fourth Circuit Court of Appeals on March 27, 2013. On March 6, 2014, the Fourth Circuit Court vacated the order of dismissal and remanded this multi-district litigation for further action, including a ruling on state tort law and its impact upon the "Contractor on the Battlefield" defenses. KBR has filed a petition for certiorari with the U.S. Supreme Court. Three amicus briefs have been filed in support of KBR's legal arguments. On June 16, 2014 the U.S. Supreme Court issued an order inviting the Solicitor General to file briefs in the burn pit litigation, expressing the views of the United States as to KBR's pending applications for writ of certiorari. We anticipate these briefs will not be filed until the fourth quarter of 2014. At this time we believe the likelihood that we would incur a loss related to this matter is remote. As of March 31, 2014, no amounts have been accrued.
	Sodium Dichromate litigation. From December 2008 through September 2009, five cases were filed in various Federal District Courts against KBR by national guardsmen and other military personnel alleging exposure to sodium dichromate at the Qarmat Ali Water Treatment Plant in Iraq in 2003. The majority of the cases were re-filed and consolidated into two cases, with one pending in the U.S. District Court for the Southern District of Texas and one pending in the U.S. District Court for the District of Oregon.  A single plaintiff case was filed on November 30, 2012 in the District of Oregon Eugene Division. Collectively, the suits represent approximately 170 individual plaintiffs all of which are current and former national guardsmen or British soldiers who claim they were exposed to sodium dichromate while providing security services or escorting KBR employees who were working at the water treatment plant, claim that the defendants knew or should have known that the potentially toxic substance existed and posed a health hazard, and claim that the defendants negligently failed to protect the plaintiffs from exposure.  The plaintiffs are claiming unspecified damages. The U.S. Army Corps of Engineers (“USACE”) was contractually obligated to provide a benign site free of war and environmental hazards before KBR's commencement of work on the site. KBR notified the USACE within two days after discovering the potential sodium dichromate issue and took effective measures to remediate the site.  Services provided by KBR to the USACE were under the direction and control of the military and therefore, KBR believes it has adequate defenses to these claims.  KBR also has asserted the Political Question Doctrine and other government contractor defenses. Additionally, studies by the U.S. government and others on the effects of exposure to the sodium dichromate contamination at the water treatment plant have found no long term harm to the soldiers.
	Texas Proceedings. On August 16, 2012, the court in the case pending in the U.S. District Court for the Southern District of Texas Court denied KBR's motion to dismiss plaintiffs' claims. On August 29, 2012, the court certified its order for immediate appeal under 28 U.S.C. § 1292(b) to the U.S. Court of Appeals for the Fifth Circuit, and stayed proceedings in the District Court pending the appeal. On November 28, 2012, the Fifth Circuit granted KBR permission to appeal. On November 7, 2013, a three judge panel of the Court returned the case to the trial court, holding the interlocutory appeal was improperly granted. We sought review by the entire court on this opinion which was denied. We have asked the trial court to stay the trial while we seek review by the U.S. Supreme Court. At this time we believe the likelihood that we would incur a loss related to this matter is remote. As of March 31, 2014, no amounts have been accrued.
	Oregon Proceedings. On November 2, 2012 in the Oregon case, a jury in the U.S. District Court for the District of Oregon issued a verdict in favor of the plaintiffs on their claims, and awarded them approximately $10 million in actual damages and $75 million in punitive damages. We filed post-verdict motions asking the court to overrule the verdict or order a new trial. On April 26, 2013, the court ruled for plaintiffs on all issues except one, reducing the total damages to $81 million which consists of $6 million in actual damages and $75 million in punitive damages. Trials for the remaining plaintiffs in Oregon will not take place until the appellate process is concluded. The court issued a final judgment on May 10, 2013, which was consistent with the previous ruling. KBR timely appealed the ruling. Briefing is complete and oral arguments have not yet been scheduled by the court. Additionally, five amicus curiae briefs have been filed in support of our arguments. Our basis for appeal include the trial court's denial of the Political Question Doctrine, the Combat Activities Exception in the Federal Tort Claims Act, a lack of personal jurisdiction over KBR in Oregon and numerous other legal issues stemming from the court's rulings before and during the trial. We have already filed proceedings to enforce our rights to reimbursement and payment pursuant to the FAR under the Restore Iraqi Oil contract ("RIO contract") with the USACE as referenced below.
	In the U.S. Court of Appeals for the Ninth Circuit, we have also filed a motion for summary reversal of the court's decision on personal jurisdiction due to a recently issued Supreme Court decision which supports our position that the Oregon court did not have jurisdiction of the case because KBR did not have contact with the state.
	At this time we believe the likelihood that we will ultimately incur a loss related to this matter is remote. As of March 31, 2014, no amounts have been accrued.
	COFC Claims. During the period of time since the first litigation was filed against us, we have incurred legal defense costs that we believe are reimbursable under the related government contract. We have billed for these costs and we have filed claims to recover the associated costs incurred to date. On November 16, 2012, we filed a suit against the U.S. government in the U.S. COFC for denying indemnity in the sodium dichromate cases (the "First COFC claim").  The RIO contract required KBR personnel to begin work in Iraq as soon as the invasion began in March 2003. Due to KBR's inability to procure adequate insurance coverage for this work, the Secretary of the Army approved the inclusion of an indemnification provision in the RIO Contract pursuant to Public Law 85-804. The First COFC claim is for more than $15 million in legal fees KBR has incurred in defending these cases and for any judgment that is issued against KBR in the litigation. On December 21, 2012, we also sent the USACE RIO Contracting Officer a certified claim for $23 million in legal costs associated with all of the sodium dichromate cases. The contracting officer declined to issue a decision on the claim. Therefore on March 6, 2013, we filed an additional claim for $23 million in the COFC (the "Second COFC claim"). The COFC granted our request to treat this claim as related to the previously mentioned, pending indemnity claim.
	On March 7, 2014, the COFC issued a ruling on the government's motion dismissing KBR's claims on procedural grounds. The decision does not prohibit us from resubmitting the claims to the contracting officer which we have done. On April 4, 2014, we submitted a supplemental certified claim to the RIO contracting officer for an additional $7 million in legal fees incurred in defending the sodium dichromate cases. On June 9, 2014, we filed an appeal to the ASBCA due to the contracting officer's failure to issue a final decision on these claims.
	Qui Tams. Of the active qui tams for which we are aware, the government has joined one of them (see DOJ FCA complaint - Iraq Subcontractor below). We believe the likelihood that a loss has been incurred in the qui tams the government has not joined is remote and as of March 31, 2014, no amounts have been accrued. Costs incurred in defending the qui tams cannot be billed to the government until those matters are successfully resolved in our favor. If successfully resolved, we can bill 80% of the costs to the government under the controlling provisions of the FAR. As of March 31, 2014, we have incurred $9 million in legal costs to date in defending ourselves in qui tams.
	Barko qui tam. Relator Harry Barko was a KBR subcontracts administrator in Iraq for a year in 2004/2005. He filed a qui tam lawsuit in June 2005 in the U.S. District Court for the District of Columbia, alleging violations of the False Claims Act by KBR and KBR subcontractors Daoud & Partners and Eamar Combined for General Trading and Contracting. The claim was unsealed in March of 2009. Barko alleges that KBR fraudulently charged the government for the purchase of laundry facilities from Daoud, that KBR paid Daoud for the construction of a substandard man-camp, that Daoud double-billed KBR for labor, that KBR improperly awarded well-drilling subcontracts to Daoud, and that Daoud charged excessive prices for these services and did not satisfactorily complete them. Barko also alleges fraudulent charges arising out of Eamar’s well-drilling services.
	The DOJ investigated Barko’s allegations and elected not to intervene. KBR filed a Motion to Dismiss alleging that the complaint was legally insufficient to state a case under the False Claims Act and this motion was denied. KBR filed its Answer to the First Amended Complaint and a Motion for Summary judgment. On February 3, 2014, Barko filed a Motion to Compel production of privileged investigative files, which KBR opposed. On March 6, 2014, in an unprecedented opinion, the Court granted the motion and ordered KBR to produce the records, thereafter also denying KBR’s motions to stay the order and for interlocutory appeal. On March 12, 2014, KBR filed its Petition for Mandamus with the D.C. Circuit Court, seeking an order reversing the trial court’s order of production. On the same day the Circuit Court issued a stay order and requested briefing. An amicus brief was filed in support of KBR’s legal arguments and the briefing process was completed in April 2014. A hearing on the mandamus was argued on May 7, 2014 and the matter is under consideration. All other scheduled activity, including a ruling on KBR’s Motion for Summary Judgment, has been stayed pending the outcome of the mandamus. We believe the likelihood that we will incur a loss related to this matter is remote, and therefore as of March 31, 2014 we have not accrued any loss provisions related to this matter.
	Chillcott qui tam. On November 21, 2011, KBR was advised of the partial unsealing of a qui tam suit brought by a former KBR employee, Karen Chillcott, in the U.S. District Court for the Central District of Illinois, Rock Island Division, alleging that KBR committed fraud in billing the government for unallowable mobilization and demobilization costs for LogCAP III and IV personnel. Chillcott alleges that these costs are unallowable under Clause H-29 of the LogCAP III Contract and Clause H-26 of the LogCAP IV Contract (the “Tour of Duty” clauses). The government declined to intervene in this suit. Although this matter is in the early stages, we have been addressing issues surrounding the H-29 clause for several years. We do not believe the complaint raises new factual issues. We believe that this case is defensible.
	The case was partially unsealed on September 10, 2013.  The DOJ investigated Chillcott’s allegations and declined to intervene. On June 28, 2013, KBR filed a Motion to Dismiss which was denied on October 25, 2013. On February 20, 2014, the Court entered a scheduling order and discovery has begun in this case. Dispositive motions are to be filed by March 1, 2015, and, if necessary, trial will begin on July 21, 2015. We believe the likelihood that we will incur a loss related to this matter is remote, and therefore as of March 31, 2014 we have not accrued any loss provisions related to this matter.
	DOJ False Claims Act complaint - Containers. In November 2012, the DOJ filed a complaint in the U.S. District Court for the Central District of Illinois in Rock Island, IL, related to our settlement of delay claims by our subcontractor, FKTC, in connection with FKTC's provision of living trailers for the bed down mission in Iraq in 2003-2004. The DOJ alleges that KBR knew that FKTC had submitted inflated costs; that KBR did not verify the costs; that FKTC had contractually assumed the risk for the costs which KBR submitted to the government; that KBR concealed information about FKTC's costs from the government; that KBR claimed that an adequate price analysis had been done when in fact one had not been done; and that KBR submitted false claims for reimbursement to the government in connection with FKTC's services during the bed down mission. Our contractual dispute with the Army over this settlement has been ongoing since 2005. We believe these sums were properly billed under our contract with the Army and are not prohibited under the LogCAP III contract. We strongly contend that no fraud was committed. On May 6, 2013, KBR filed a motion to dismiss. In March 2014 the motion to dismiss was denied. We filed our answer on May 2, 2014 and on May 23, 2014 the government filed a Motion to Strike certain affirmative defenses. We are contesting that motion and proceeding with discovery. At this time, we believe the likelihood that we would incur a loss related to this matter is remote. As of March 31, 2014, no amounts have been accrued.
	DOJ False Claims Act complaint - Iraq Subcontractor. In January 2014, the DOJ filed a complaint in the U.S. District Court for the Central District of Illinois in Rock Island, IL, against KBR and two former KBR subcontractors alleging that three former KBR employees were offered and accepted kickbacks from these subcontractors in exchange for favorable treatment in the award and performance of subcontracts to be awarded during the course of KBR's performance of the LogCAP III contract in Iraq. The complaint alleges that as a result of the kickbacks, we submitted invoices with inflated or unjustified subcontract prices, resulting in alleged violations of the False Claims Act and the Anti-Kickback Act. While the suit is new, the DOJ's investigation dates back to 2004. We self-reported most of the violations and tendered credits to the government as appropriate. On April 22, 2014, we filed our answer and on May 13, 2014 the government filed a Motion to Strike certain affirmative defenses. We are contesting this motion. As of March 31, 2014, we have accrued our best estimate of probable loss related to an unfavorable settlement of this matter recorded in "other liabilities" on our condensed consolidated balance sheets. At this time, we believe the likelihood that we would incur a loss related to this matter in excess of the amounts we have accrued is remote.
	Other Matters
	Claims. We have filed claims with the government related to payments not yet received for costs incurred under various government contracts. Included in our condensed consolidated balance sheets are claims for costs incurred under various government contracts totaling $244 million at March 31, 2014. These claims relate to disputed costs and/or contracts where our costs have exceeded the government's funded value on the task order. We have $115 million of claims primarily from de-obligated funding on certain task orders that were also subject to Form 1s relating to certain DCAA audit issues discussed above.  We believe such disputed costs will be resolved in our favor at which time the government will be required to obligate funds from appropriations for the year in which resolution occurs. These claims are recorded in "claims and accounts receivable" on our condensed consolidated balance sheets.  Of the remaining claims balance of $129 million, $122 million is recorded in "claims and accounts receivable" and the remaining is recorded in "CIE" on our condensed consolidated balance sheets. These claims represent costs for which incremental funding is pending in the normal course of business along with specific items listed above. The claims outstanding at March 31, 2014 are considered to be probable of collection and have been previously recognized as revenue.

	Litigation and regulatory matters related to the Company’s restatement of its 2013 annual financial statements
	After the Company announced it would be restate its 2013 annual financial statements, two complaints were filed in the federal district court for the Southern District of Texas seeking class status for our shareholders and alleging damages on their behalf arising from the matters giving rise to the restatement. The named defendants are the Company, our former chief executive officer and our current and former chief financial officers. These matters are at a very early stage, with non-specific allegations and with no lead plaintiff yet chosen; therefore, we are not able at this time to determine the likelihood of loss, if any, arising from these matters.
	In addition, a shareholder derivative complaint has been filed in the federal district court for the Southern District of Texas on behalf of the Company naming all of our directors, past and present, as defendants and the Company as a nominal defendant. This matter is at a very early stage and so we are not able at this time to determine the likelihood of loss, if any, arising from this matter.
	We have also received requests for information from the Securities Exchange Commission as part of an informal inquiry seeking to better understand the matters resulting in the restatement of our 2013 annual financial statements. We are fully cooperating with the Commission to ensure they receive the information they have requested.
	Foreign Corrupt Practices Act (“FCPA”) Investigations
	In February 2009, KBR LLC, entered a guilty plea to violations of the FCPA in the United States District Court, Southern District of Texas, Houston Division, related to the Bonny Island investigation. The plea agreement reached with the DOJ resolved all criminal charges in the DOJ’s investigation and called for the payment of a criminal penalty. In addition, we settled a civil enforcement action by the U.S. Securities and Exchange Commission. We also agreed to a period of probation for a three year period that ended on February 17, 2012, after which the monitor certified that KBR’s current anti-corruption compliance program has been appropriately designed and implemented to ensure future compliance with the FCPA and other applicable anti-corruption laws.
	In February 2011, M.W. Kellogg Limited (“MWKL”) reached a settlement with the U.K. Serious Fraud Office (“SFO”) in which the SFO accepted that MWKL was not party to any unlawful conduct and assessed a civil penalty. The settlement terms included a full release of all claims against MWKL, its current and former parent companies, subsidiaries and other related parties including their respective current or former officers, directors and employees with respect to the Bonny Island project.
	On March 18, 2013, we received a letter from the African Development Bank Group ("ADBG") stating they are in the process of opening a formal investigation into corruption related to the Bonny Island project discussed above. We have entered into a Negotiated Resolution Agreement with the ADBG that includes a financial penalty equivalent to approximately $6.6 million, of which $0.3 million has been paid and the remainder is in progress, having been delayed awaiting approval from the National Bank of Ethiopia. We have also agreed to a three-year debarment from ADBG-sponsored contracts of three inactive Madeira, Portugal-based companies that KBR and its three joint venture partners used to participate in the Bonny Island project.
	PEMEX and PEP Arbitration
	In 1997 and 1998, we entered into three contracts with PEP, the project owner, to build offshore platforms, pipelines and related structures in the Bay of Campeche, offshore Mexico. PEP is part of PEMEX, the national oil company of Mexico. The three contracts were known as EPC 1, EPC 22 and EPC 28. All three projects encountered significant schedule delays and increased costs due to problems with design work, late delivery and defects in equipment, increases in scope and other changes. During 2008, we were successful in litigating and collecting on valid international arbitration awards against PEP on the EPC 22 and EPC 28 projects.
	EPC 1
	U.S. Proceedings. PEP took possession of the offshore facilities of EPC 1 in March 2004 after having achieved oil production but prior to our completion of our scope of work pursuant to the contract. As a result of the ensuing dispute, we filed for arbitration with the International Chamber of Commerce ("ICC") in 2004 claiming recovery of damages of approximately $323 million for the EPC 1 project. PEP subsequently filed counterclaims totaling $157 million. In December 2009, the ICC ruled in our favor, and we were awarded a total of approximately $351 million including legal and administrative recovery fees as well as interest. PEP was awarded approximately $6 million on counterclaims, plus interest on a portion of that sum. In connection with this award, we recognized a gain of $117 million net of tax in 2009.
	Our collection efforts have been ongoing and have involved multiple actions. On November 2, 2010, we received a judgment in our favor in the U.S. District Court for the Southern District of New York to recognize the award in the U.S. of approximately $356 million plus Mexican value added tax and interest thereon until paid. PEP initiated an appeal to the U.S. Court of Appeals for the Second Circuit. On February 16, 2012, the Second Circuit issued an order remanding the case to the District Court to consider if the decision of the Collegiate Court in Mexico, described below, would have affected the trial court’s ruling. The District Court Judge held a three day hearing on April 10 -12, 2013 to hear evidence about the Collegiate Court decision, which annulled the arbitration award and about whether we have a full and fair remedy in Mexico.
	Both parties filed briefs and hearings were conducted in May, July and September 2012 at which time the matter was put on informal stay and KBR was ordered to file suit in Mexican courts in order to determine if such remedies were, in fact, available. As requested by the District Court, we filed suit in Mexico on November 6, 2012 in the Tax and Administrative Court. On December 3, 2012, the Mexican Tax and Administrative Court decided not to admit the lawsuit, and the suit could not proceed.
	On August 27, 2013, the District Court entered an order stating it would confirm the award even though it had been annulled in Mexico. On September 25, 2013, the District Court entered the signed final judgment of $465 million to be recovered, which includes the original confirmation of the arbitration award and approximately $106 million for performance bonds discussed below, plus interest. The judgment also requires that each party pay value added tax on the amounts each has been ordered to pay. PEP filed a notice of appeal to the U.S. Court of Appeals for the Second Circuit on October 16, 2013 and posted security for the judgment pending appeal. The case is now on appeal before the U.S. Court of Appeals. Briefing is now closed and we are awaiting scheduling of oral argument.
	Mexico Proceedings. PEP's attempt to nullify the award in Mexico was rejected by the Mexican trial court in June 2010. PEP then filed an “amparo” action on the basis that its constitutional rights had been violated and this action was denied by the Mexican court in October 2010. PEP subsequently appealed the adverse decision with the Collegiate Court in Mexico on the grounds that the arbitration tribunal did not have jurisdiction and that the award violated the public order of Mexico. Although these arguments were presented in the initial nullification and amparo action, and were rejected in both cases, in September 2011, the Collegiate Court ruled that PEP, by administratively rescinding the contract in 2004, deprived the arbitration panel of jurisdiction thereby nullifying the arbitration award. The Collegiate Court's decision is contrary to the ruling received from the ICC as well as the other Mexican courts which have denied PEP's repeated attempts to nullify the arbitration award. We also believe the Collegiate Court's decision is contrary to Mexican law governing contract arbitration. However, we do not expect the Collegiate Court's decision to affect our ability to ultimately collect the ICC arbitration award in the U.S. due to the posting of security for the judgment pending appeal and significant assets of PEP in the U.S.
	Luxembourg Collection Proceedings. In 2013, we petitioned the Luxembourg court to issue two seizure orders on the assets of PEP and PEMEX that have been served on a number of banks and financial institutions in that country, as we believe these institutions may have PEP and PEMEX assets that are subject to seizure which could be used to satisfy our award. However under Luxembourg procedure, we will not find out the value of the seized assets until the proceeding is validated, which will take several months. The first seizure order is for the New York award confirmation; the second seizure order is for the performance bonds payment discussed below. PEP and PEMEX contested the first seizure order and the matter was heard on May 27, 2013 where their petition to lift the seizure order was denied. PEP and PEMEX filed an appeal and on December 18, 2013, the Luxembourg Court of Appeals stated it was dissolving the first seizure order against both PEP and PEMEX. This decision is being appealed to the Luxembourg Supreme Court.
	Concurrent with our filing of the seizure order, we filed an action in Luxembourg seeking to enforce the ICC award. In March 2013, we received an order from the Luxembourg court recognizing the award. On June 25, 2013, PEMEX and PEP filed an appeal challenging the enforcement order. We are awaiting scheduling of the hearing on the appeal. We cannot begin the validation proceeding until the appeal is concluded and this could take several months.
	North American Free Trade Agreement ("NAFTA") Collection Proceedings. We filed arbitration under NAFTA against Mexico and asserted a claim to have our award paid. The parties have selected the arbitrators, a chairman has been named and the first procedural order has been entered.
	We will continue to pursue our remedies in the U.S., Luxembourg and other jurisdictions where we determine have assets which can be used to pay the award.
	Performance Bonds
	In connection with the EPC 1 project, we had approximately $80 million in outstanding performance bonds furnished to PEP when the project was awarded. The bonds were written by a Mexican bond company and backed by a U.S. insurance company which is indemnified by KBR. As a result of the ICC arbitration award in December 2009, the panel determined that KBR had performed on the project, and we believe recovery on the bonds by PEP was precluded by the ICC Award.  PEP filed an action in Mexico in June 2010 against the Mexican bond company to collect the bonds even though the arbitration award determined the limited amounts to be paid to PEP on their counterclaims and offset those claims against the award in favor of KBR.
	After multiple proceedings in various Mexican courts, we paid $108 million (which includes the $106 million discussed above and $2 million in legal and banking fees) on June 17, 2013 following a demand for payment which includes principal, interest and expenses to the Mexican bond company. On June 21, 2013, we filed a supplemental writ in Luxembourg to cover the amounts paid to the bonding company on the performance bonds. That writ was granted and served on Luxembourg banks. PEP and PEMEX have refused service in Luxembourg and we are currently serving that writ on PEP and PEMEX. Since the decision by the Luxembourg Court of Appeals dissolved the first writ as to PEMEX, we have lifted the second writ as to PEMEX. The second writ remains in effect as to PEP.
	On September 25, 2013, the U.S. District Court for the Southern District of New York entered the signed final judgment which included the amount paid on the bonds plus interest. We will pursue reimbursement of the sums paid in the current enforcement action in the U.S. District Court for the Southern District of New York, the courts of Luxembourg, or by our recently filed NAFTA arbitration seeking to recover the bonds as an unlawful expropriation of assets by the government of Mexico.
	Consistent with our treatment of claims, we have recorded $401 million in claims and accounts receivable as we believe it is probable we will recover the amounts awarded to us, including interest, expenses and the amounts we paid on the bonds. PEP has sufficient assets in the U.S. and Luxembourg, which we believe we will be able to attach as a result of the recognition of the ICC arbitration award. Although it is possible we could resolve and collect the amounts due from PEP in the next 12 months, we believe the timing of the collection of the award is uncertain; therefore, consistent with our prior practice, as of March 31, 2014, we continue to classify the amount due from PEP, including the amounts paid on the performance bonds as long term.
	ENI Holdings, Inc. (the Roberts & Schaefer Company)
	On December 21, 2010, we completed the acquisition of 100% of the outstanding common shares of ENI Holdings, Inc. (“ENI”). ENI was the parent to the Roberts & Schaefer Company, a privately held EPC services company acquired by us in 2010. The purchase price was $280 million plus estimated working capital of $17 million which included cash acquired of $8 million. The total net cash paid at closing of $289 million is subject to an escrowed holdback. As of March 31, 2014, the remaining escrowed holdback was $25 million and primarily related to security for indemnification obligations.
	Delaware Litigation. KBR withheld the $25 million in escrow due to KBR's claims under the indemnification provisions of the stock purchase agreement. In December 2012, ENI filed a lawsuit in Delaware Chancery Court alleging KBR is wrongfully withholding the escrowed funds. KBR filed a counterclaim for indemnity and fraud under the terms of the stock purchase agreement. In March 2013, ENI filed a motion to dismiss. The Court denied in part ENI's motion to dismiss KBR's counterclaims in their entirety. The case is proceeding and expected to be schedule for trial in mid-2015.
	Working Capital Arbitration. Due to several disputed items related to the calculation of working capital, a working capital arbitration proceeding was initiated by KBR and ENI pursuant to the terms of the stock purchase agreement. KBR asked the Delaware court to stay the working capital arbitration pending the outcome of the litigation but the court denied our request. The working capital arbitration took place in December 2013. A determination was issued in February 2014 indicating ENI was entitled to a working capital adjustment of approximately $2.4 million, which is less than the amount to which ENI claimed they were entitled. This payment was made to ENI in the first quarter of 2014. We consider this matter concluded.

	In connection with our initial public offering in November 2006 and the separation of our business from Halliburton, we entered into various agreements, including, among others, a master separation agreement, transition services agreements and a tax sharing agreement. Pursuant to our master separation agreement, we agreed to indemnify Halliburton for, among other matters, past, present and future liabilities related to our business and operations. We agreed to indemnify Halliburton for liabilities under various outstanding and certain additional credit support instruments relating to our business and for liabilities under litigation matters related to our business. Halliburton agreed to indemnify us for, among other things, liabilities unrelated to our business, for certain other agreed matters relating to the investigation of FCPA and related corruption allegations for the Barracuda-Caratinga project and for other litigation matters related to Halliburton’s business. See Note 11 for further discussion on the FCPA and related corruption allegations. Under the transition services agreements, Halliburton provided various interim corporate support services to us and we provided various interim corporate support services to Halliburton. The tax sharing agreement provides for certain allocations of U.S. income tax liabilities and other agreements between us and Halliburton with respect to tax matters.
	During the fourth quarter of 2011, Halliburton provided notice and demanded payment for $256 million that it alleged we owed under the tax sharing agreement for various other tax-related transactions pertaining to periods prior to our separation from Halliburton. We believe that the master separation agreement precludes the filing of this claim.
	On July 3, 2012, KBR requested an arbitration panel be appointed to resolve certain intercompany issues arising under the master separation agreement before issues in dispute under the tax sharing agreement were submitted to the designated accounting referee as provided for under the terms of the tax sharing agreement.  We believe these intercompany issues were settled and released as a result of our separation from Halliburton in 2007. Halliburton subsequently challenged the arbitration panel's jurisdiction over this dispute in Texas State Court. The Texas State Court denied Halliburton's request and Halliburton filed an appeal which is awaiting a decision.
	In May 2013, an arbitration hearing was held on the matters related to the master separation agreement. On June 24, 2013 the arbitration panel ruled that claims brought by Halliburton against KBR under the tax sharing agreement were required to have been brought before an arbitration panel within two years of the date the claim arose or would reasonably have been discovered by the claimant and that the parties were to return to the accounting referee within thirty days for determination of the remaining claims under the tax sharing agreement.  The remaining tax-related issues in dispute were referred to the accounting referee as provided for under the terms of the tax sharing agreement.
	On October 9, 2013, the accounting referee issued a report stating that KBR owed Halliburton approximately $105 million with each party bearing its own costs related to the matter. As a result, we increased our tax provision by $38 million, reduced Paid-in capital by $7 million and recognized a deferred tax asset of $29 million for available foreign tax credits. KBR has filed a motion requesting the Texas State Court to confirm the ruling and Halliburton has responded requesting that the ruling be vacated. The decision on these motions is pending. As of March 31, 2014, we have recorded $106 million to our "Payable to former parent" on our condensed consolidated balance sheets, which is net of $22 million awarded to KBR by the accounting referee.
	As discussed above, the arbitration panel had found several of Halliburton's unspecified claims to be time barred. On January 16, 2014, we asked this arbitration panel to determine if any of Halliburton's claims submitted to the referee were time barred and to correctly interpret the relevant agreements. On March 14, 2014, the arbitration panel ruled that it no longer had jurisdiction to hear this dispute and that a new arbitration demand was required. We intend to institute another arbitration proceeding once the Texas Court of Appeals rules on Halliburton's challenge to the arbitration panel's jurisdiction.
	Barracuda-Caratinga Project Tax Dispute
	In June 2000, we entered into a contract with Barracuda & Caratinga Leasing Company B.V. ("BCLC"), the project owner and claimant, to develop the Barracuda and Caratinga crude oilfields, which are located off the coast of Brazil. Petrobras is a contractual representative that controls the project owner. In November 2007, we executed a settlement agreement with the project owner to settle all outstanding project issues except for the bolts arbitration discussed below.
	In March 2006, Petrobras notified us they had submitted a claim to arbitration of $220 million plus interest for the cost of monitoring and replacing defective stud bolts and, in addition, all of the costs and expenses of the arbitration including the cost of attorneys’ fees. The arbitration was conducted in New York under the guidelines of the United Nations Commission on International Trade Law. In September 2011, the arbitration panel awarded the claimant approximately $193 million.
	In January 2013, Halliburton paid $219 million to the claimant in payment of the award plus interest and the matter is considered concluded. We believe the arbitration award to Petrobras is deductible by KBR for tax purposes and the indemnification payment will be treated by KBR for tax purposes as a contribution to capital and accordingly is not taxable. In 2011 and 2012, we recorded discrete tax benefits of $71 million and $8 million, respectively. We have reviewed this matter in light of the direct payment by Halliburton to BCLC and its public announcement that they have recorded a tax benefit related to this transaction. Based on advice from outside legal counsel, we have determined that it is more likely than not that we are the proper taxpayer to recognize this benefit although the underlying uncertainties with respect to the tax treatment of the transaction may ultimately lead to alternate outcomes.

	Share Repurchases
	On February 25, 2014, our Board of Directors authorized a plan to repurchase up to $350 million of our outstanding common shares, which replaces and terminates the August 26, 2011 share repurchase program. The authorization does not obligate the company to acquire any particular number of common shares and may be commenced, suspended or discontinued without prior notice. The newly authorized share repurchase program operates alongside the existing share maintenance program which we may use to repurchase shares vesting as part of employee compensation programs. The share repurchases are intended to be funded through the company’s current and future cash and the authorization does not have an expiration date. The table below presents information on our share repurchase activities under the share repurchase authorization.
	Millions of dollars	2014
	Authorization amount	$	350
	Repurchases under the Authorization of 1,570,346 shares at the average price of $27.70	43
	Remaining authorization amount as of March 31,	$	307
	In addition to the shares repurchased under the newly authorized share repurchase program, we also spent $13 million to repurchase shares under the existing share maintenance program.
	Subsequent to March 31, 2014, we spent an additional $38 million to repurchase 1,409,275 shares at the average price of $26.74 per share. As of April 16, 2014, we have repurchased a total of 3,436,521 shares at the average price of $27.29 per share for a total of $94 million and have made no share repurchases subsequent to that date.

Income Per Share	'
	Income (loss) per Share
	Basic income (loss) per share is based upon the weighted average number of common shares outstanding during the period. Dilutive income (loss) per share includes additional common shares that would have been outstanding if potential common shares with a dilutive effect had been issued using the treasury stock method.
	A reconciliation of the number of shares used for the basic and diluted income per share calculations is as follows:
		Three Months Ended March 31,
	Millions of shares	2014	2013
	Basic weighted average common shares outstanding	146	147
	Stock options and restricted shares	—	1
	Diluted weighted average common shares outstanding	146	148
	For purposes of applying the two-class method in computing earnings per share, there were no net earnings allocated to participating securities for the three months ended March 31, 2014 and $0.3 million, or a negligible amount per share, for the three months ended March 31, 2013. The diluted earnings per share calculation did not include 1.8 million and 1.2 million antidilutive weighted average shares for three months ended March 31, 2014 and 2013, respectively.

	Recent Accounting Pronouncements
	On May 28, 2014, the FASB issued Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers. This ASU supercedes the revenue recognition requirements in Accounting Standards Codification 605 - Revenue Recognition and most industry-specific guidance throughout the Codification. The standard requires that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. This ASU is effective on January 1, 2017 and should be applied retrospectively to each prior reporting period presented or retrospectively with the cumulative effect of initially applying the ASU recognized at the date of initial application. We are in the process of assessing the impact of the adoption of ASU 2014-09 on our financial position, results of operations or cash flows. We have not yet selected a transition method nor have we determined the effect of the the standard on our ongoing financial reporting.
	On January 24, 2014, the FASB issued ASU No. 2014-05, Service Concession Arrangements. A service concession agreement is an arrangement between a public-sector entity and an operating entity under which the operating entity operates the grantor's infrastructure. This ASU specifies that an operating entity should not account for a service concession arrangement within the scope of this ASU as a lease in accordance with ASC 840 - Leases. An operating entity should refer to other ASUs as applicable to account for various aspects of a service concession arrangement. The amendments also specify that the infrastructure used in a service concession agreement should not be recognized as property, plant and equipment of the operating entity. The amendments in this ASU are effective using a modified retrospective approach for annual reporting periods beginning after December 15, 2014 and interim periods within those annual periods. The adoption of ASU 2014-05 is not expected to have a material impact on our financial position, results of operations or cash flows.

Accounting Policies [Abstract]	'
Principles of consolidation	'
	Principles of consolidation
	Our condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States ("U.S. GAAP") and include the accounts of KBR and our wholly owned and majority-owned, controlled subsidiaries and variable interest entities of which we are the primary beneficiary. We account for investments over which we have significant influence but not a controlling financial interest using the equity method of accounting. See Note 7 for further discussion on our equity investments and variable interest entities. The cost method is used when we do not have the ability to exert significant influence. All material intercompany balances and transactions are eliminated in consolidation.
	Certain prior year amounts have been reclassified to conform to the current year presentation on the condensed consolidated statement of income, condensed consolidated balance sheets and the condensed consolidated statements of cash flows. For the three months ended March 31, 2014, we reclassified equity in earnings of unconsolidated affiliates from revenues to a separate component of operating income on our condensed consolidated statement of income. We reclassified the 2013 amounts to conform to our revised presentation as a component of operating income but not a component of revenues.
	We have evaluated all events and transactions occurring after the balance sheet date but before the financial statements were issued and have included the appropriate disclosures.
Use of estimates	'
	Use of estimates
	The preparation of our condensed consolidated financial statements in conformity with U.S. GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period, including:
	•	project revenues, costs and profits on engineering, construction, pipe fabrication and module assembly, and government services contracts, including recognition of estimated losses on uncompleted contracts,
	•	uncollectible receivables, claims to and from clients, recoveries of costs from subcontractors, vendors and others,
	•income taxes and related valuation allowances and tax uncertainties,
	•recoverability of goodwill,
	•other intangibles and long-lived assets and related estimated lives,
	•recoverability of equity method and cost method investments,
	•valuation of pension obligations,
	•accruals for estimated liabilities and litigation outcomes,
	•consolidation of variable interest entities,
	•and valuation of stock-based compensation.
	In accordance with normal practice in the construction industry, we include in current assets and current liabilities amounts related to construction contracts realizable and payable over a period in excess of one year. Actual amounts may differ from those included in the accompanying condensed consolidated financial statements, if the underlying estimates and assumptions upon which the financial statements are based change in the future.
Gross Profit [Policy Text Block]	'
	Gross Profit
	Gross profit represents business segment revenue less the cost of revenue, which includes business segment overhead costs directly attributable to the business segment. See Note 2 for our discussion on Business Segment gross profit (loss).
Allowance for bad debts	'
	Accounts Receivable
	Accounts receivable are recorded at the invoiced amount based on contracted prices. Amounts collected on accounts receivable are included in net cash provided by operating activities in the condensed consolidated statements of cash flows.
	We establish an allowance for doubtful accounts based on the assessment of the clients’ willingness and ability to pay. In addition to such allowances, there are often items in dispute or being negotiated that may require us to make an estimate as to the ultimate outcome. Past due receivable balances are written off when our internal collection efforts have been unsuccessful in collecting the amounts due. See Note 4 for our discussion on accounts receivable.
	Retainage, included in accounts receivable, represents amounts withheld from billings by our clients pursuant to provisions in the contracts and may not be paid to us until the completion of specific tasks on the project and for longer periods, in some instances. Retainage may also be subject to restrictive conditions such as performance guarantees. Our retainage receivable excludes amounts withheld by the United States ("U.S.") government on certain contracts. See Note 10 for our discussion on U.S. government receivables.
Costs In Excess Of Billings And Billings In Excess Of Costs [Policy Text Block]	'
	Costs and Estimated Earnings in Excess of Billings on Uncompleted Contracts, Including Claims, and Advanced Billings and Billings in Excess of Costs and Estimated Earnings on Uncompleted Contracts
	Costs and estimated earnings in excess of billings on uncompleted contracts ("CIE") represent the excess of contract costs and profits recognized to date using the percentage-of-completion method over billings to date on certain contracts. Billings in excess of costs and estimated earnings on uncompleted contracts ("BIE") represents the excess of billings to date over the amount of contract costs and profits recognized to date using the percentage-of-completion method on certain contracts. See Note 5 for our discussion on CIE and BIE.
Goodwill and other intangibles	'
	Goodwill
	Effective January 1, 2014, we reorganized four of the five reporting units in the Infrastructure, Government and Power ("IGP") business segment into three geographic-based units. This reorganization allows the IGP business segment to focus its full-scope engineering, procurement, construction and defense services to clients on a more local level. We have concluded that each of these geographic-based units will be considered a separate reporting unit for goodwill impairment testing purposes. As a result, we performed an additional impairment test on the three newly reorganized reporting units on January 1, 2014 as required by ASC 350-20, utilizing the same methodology as our annual goodwill impairment test, and no indication of impairment was identified. For more detail on our methodology and assumptions, see "Critical Accounting Policies" in our 2013 Annual Report on Form 10-K/A.
Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]	'
	Share-based Compensation
	Effective January 1, 2014, we changed our methodology for estimating the expected term of our option awards and we will no longer utilize the simplified method. We will measure all future stock option awards using an expected term based on KBR’s historical experience.
