Debt Disclosure [Abstract]
Credit Facility	NOTE 3 – CREDIT FACILITY On June 24, 2014, B&W entered into a Second Amended and Restated Credit Agreement (the “New Credit Agreement”) with a syndicate of lenders and letter of credit issuers, and Bank of America, N.A., as administrative agent, which amends and restates our previous Credit Agreement dated June 8, 2012. The New Credit Agreement provides for revolving credit borrowings and issuances of letters of credit in an aggregate amount of up to $1.0 billion and a term loan facility of up to $300 million, $150 million of which was drawn on the closing date of the New Credit Agreement. The remaining $150 million commitment for the term loan remains available under a delayed draw feature through December 31, 2014. The New Credit Agreement is scheduled to mature on June 24, 2019. The proceeds of the New Credit Agreement are available for the issuance of letters of credit, working capital needs and other general corporate purposes. The New Credit Agreement includes provisions that allow for additional financial institutions to become lenders, or for any existing lender to increase its commitment thereunder, subject to an aggregate maximum of $400 million for all incremental term loan, revolving credit borrowings and letter of credit commitments. The New Credit Agreement is guaranteed by substantially all of B&W’s wholly owned domestic subsidiaries. Obligations under the New Credit Agreement are secured by first-priority liens on certain assets owned by B&W and the guarantors (other than our subsidiaries comprising our Nuclear Operations and Technical Services segments). If the corporate family rating of B&W and its subsidiaries from Moody’s is Baa3 or better (with a stable outlook or better), the corporate rating of B&W and its subsidiaries from S&P is BBB- or better (with a stable outlook or better), and other conditions are met, the liens securing obligations under the New Credit Agreement will be released, subject to reinstatement upon the terms set forth in the New Credit Agreement. B&W’s current corporate family rating from Moody’s is Ba1 and its corporate rating from S&P is BB+. The New Credit Agreement requires interest payments on revolving loans on a periodic basis until maturity. Beginning with the quarter following that in which the term loan commitment ends, we are required to make quarterly amortization payments on the term loan portion of the New Credit Agreement in an amount equal to 1.25% of the aggregate principal amount of the term loan facility that is utilized. We may prepay all loans under the New Credit Agreement at any time without premium or penalty (other than customary LIBOR breakage costs), subject to notice requirements. We are also required to make certain prepayments on any outstanding term loans under the New Credit Agreement after receipt of cash proceeds from certain asset sales or other events, subject to certain exceptions and our right to reinvest such proceeds in certain circumstances, all as more particularly set forth in the New Credit Agreement. The New Credit Agreement contains financial covenants relating to leverage and interest coverage and includes covenants that restrict, among other things, debt incurrence, liens, investments, acquisitions, asset dispositions, dividends, prepayments of subordinated debt and mergers. At June 30, 2014, we were in compliance with all of the covenants set forth in the New Credit Agreement. Loans outstanding under the New Credit Agreement bear interest at our option at either the Eurocurrency rate plus a margin ranging from 1.25% to 2.00% per year or the base rate (the highest of the Federal Funds rate plus 0.50%, the one month Eurocurrency rate plus 1.00%, or the administrative agent’s prime rate) plus a margin ranging from 0.25% to 1.00% per year. The applicable margin for loans varies depending on the credit ratings of the New Credit Agreement. Under the New Credit Agreement, we are charged a commitment fee on the unused portions of the New Credit Agreement, and that fee varies between 0.200% and 0.350% per year depending on the credit ratings of the New Credit Agreement. Additionally, we are charged a letter of credit fee of between 1.250% and 2.000% per year with respect to the amount of each financial letter of credit issued under the New Credit Agreement and a letter of credit fee of between 0.725% and 1.125% per year with respect to the amount of each performance letter of credit issued under the New Credit Agreement, in each case depending on the credit ratings of the New Credit Agreement. We also pay customary fronting fees and other fees and expenses in connection with the issuance of letters of credit under the New Credit Agreement. In connection with entering into the New Credit Agreement, we paid upfront fees to the lenders thereunder, and arrangement and other fees to the arrangers and agents of the New Credit Agreement. At June 30, 2014, borrowings outstanding totaled $150.0 million and $113.8 million under our term loan and revolving line of credit, respectively, and letters of credit issued under the New Credit Agreement totaled $173.0 million, resulting in $863.2 million available for borrowings or to meet letter of credit requirements. Based on the current credit ratings of the New Credit Agreement, beginning in August 2014 the applicable margin for Eurocurrency rate loans is 1.375%, the applicable margin for base rate loans is 0.375%, the letter of credit fee for financial letters of credit is 1.375%, the letter of credit fee for performance letters of credit is 0.80%, and the commitment fee for unused portions of the New Credit Agreement is 0.225%. The New Credit Agreement does not have a floor for the base rate or the Eurocurrency rate. The New Credit Agreement generally includes customary events of default for a secured credit facility. If any default occurs under the New Credit Agreement, or if we are unable to make any of the representations and warranties in the New Credit Agreement, we will be unable to borrow funds or have letters of credit issued under the New Credit Agreement.
