Debt Disclosure [Abstract]
Debt and Other Credit Facilities	Debt and Other Credit Facilities Credit Agreement On December 2, 2011, we entered into a $1 billion, five-year unsecured revolving credit agreement (the “Credit Agreement”) with a syndicate of international banks. The Credit Agreement is available for cash borrowings and the issuance of letters of credit related to general corporate needs. The Credit Agreement expires in December 2016; however, given that projects generally require letters of credit that extend beyond one year in length, we will likely need to enter into a new or amended credit agreement no later than 2015. Amounts drawn under the Credit Agreement will bear interest at variable rates, per annum, based either on (1) the London interbank offered rate (“LIBOR”) plus an applicable margin of 1.50% to 1.75%, or (2) a base rate plus an applicable margin of 0.50% to 0.75%, with the base rate equal to the highest of (a) reference bank’s publicly announced base rate, (b) the Federal Funds Rate plus 0.5%, or (c) LIBOR plus 1%. The amount of the applicable margin to be applied will be determined by the Company’s ratio of consolidated debt to consolidated EBITDA for the prior four fiscal quarters, as defined in the Credit Agreement. The Credit Agreement provides for fees on letters of credit issued under the Credit Agreement at a rate equal to the applicable margin for LIBOR-based loans, except for performance letters of credit, which are priced at 50% of such applicable margin. KBR pays an issuance fee of 0.15% of the face amount of a letter of credit. KBR also pays a commitment fee of 0.25%, per annum, on any unused portion of the commitment under the Credit Agreement. As of March 31, 2015, there were $165 million in letters of credit and no cash borrowings outstanding. The Credit Agreement contains customary covenants which include financial covenants requiring maintenance of a ratio of consolidated debt to consolidated EBITDA not greater than 3.5 to 1 and a minimum consolidated net worth, as defined in the Credit Agreement. In anticipation of our reorganization and the expected impairment and restructuring charges, in December 2014 we obtained an amendment to the Credit Agreement which reset the minimum consolidated net worth to $1.5 billion plus 50% of consolidated net income for each quarter beginning December 31, 2014 and 100% of any increase in shareholders’ equity attributable to the sale of equity interests. In April 2015, we obtained an amendment to the Consolidated Net Worth (as defined in the Credit Agreement) to exclude the effects of changes in foreign currency translation adjustments from Shareholders’ Equity, as defined in the Credit Agreement, for financial covenant purposes beginning January 1, 2015. As a result of this amendment, on March 31, 2015, we were in compliance with our financial covenants. The Credit Agreement contains a number of other covenants restricting, among other things, our ability to incur additional liens and indebtedness, enter into asset sales, repurchase our equity shares and make certain types of investments. Our subsidiaries are restricted from incurring indebtedness, except if such indebtedness relates to purchase money obligations, capitalized leases, refinancing or renewals secured by liens upon or in property acquired, constructed or improved in an aggregate principal amount not to exceed $200 million outstanding at any time. Additionally, our subsidiaries may incur unsecured indebtedness not to exceed $200 million in aggregate outstanding principal amount at any time. We are also permitted to repurchase our equity shares, provided that no such repurchases shall be made from proceeds borrowed under the Credit Agreement, and that the aggregate purchase price and dividends paid after December 2, 2011, does not exceed the Distribution Cap (equal to the sum of $750 million plus the lesser of (1) $400 million and (2) the amount received by us in connection with the arbitration and subsequent litigation of the PEP contracts as discussed in Note 13 to our condensed consolidated financial statements). At March 31, 2015, the remaining availability under the Distribution Cap was approximately $441 million. Nonrecourse Project Debt Fasttrax Limited, a joint venture in which we indirectly own a 50% equity interest with an unrelated partner, was awarded a concession contract in 2001 with the U.K. Ministry of Defense ("MoD") to provide a Heavy Equipment Transporter Service to the British Army. See Note 8 to our condensed consolidated financial statements for further discussion on the joint venture. Under the terms of the arrangement, Fasttrax Limited operates and maintains 91 heavy equipment transporters (“HETs”) for a term of 22 years. The purchase of the HETs by the joint venture was financed through two series of bonds secured by the assets of Fasttrax Limited and a bridge loan totaling approximately £84.9 million (approximately $120 million at the exchange rate on the date of the transaction). The secured bonds are an obligation of Fasttrax Limited and are not a debt obligation of KBR as they are nonrecourse to the joint venture partners. Accordingly, in the event of a default on the notes, the lenders may only look to the assets of Fasttrax Limited for repayment. The bridge loan of approximately £12.2 million (approximately $17 million at the exchange rate on the date of the transaction) was replaced when the joint venture partners funded their equity and subordinated debt contributions in 2005. The secured bonds were issued in two classes consisting of Class A 3.5% Index Linked Bonds in the amount of £56 million (approximately $79 million at the exchange rate on the date of the transaction) and Class B 5.9% Fixed Rate Bonds in the amount of £16.7 million (approximately $24 million at the exchange rate on the date of the transaction). Semi-annual payments on both classes of bonds commenced in March 2005 and will continue through maturity in 2021. The subordinated notes payable to each of the partners initially bear interest at 11.25% increasing to 16% over the term of the notes until maturity in 2025. Semi-annual payments on the subordinated notes commenced in March 2006. For financial reporting purposes, only our partner's portion of the subordinated notes appears in the condensed consolidated financial statements.
