Restricted  Cash  and  Cash  Equivalents


At  June  30,  2009,  we had restricted cash and cash equivalents totaling $81.2million,  $43.9  million of which was held in restricted foreign accounts, $28.8million  was  held  in  escrow pending final payment on a legal settlement, $2.8million was held as cash collateral for letters of credit, $5.0 million was heldfor  future  decommissioning  of  facilities,  and $0.7 million was held to meetreinsurance  reserve  requirements  of  our  captive  insurance  companies.

Warranty  Expense


We  generally  accrue  estimated  expense  to  satisfy  contractual  warrantyrequirements  of our Government Operations and Power Generation Systems segmentswhen we recognize the associated revenue on the related contracts.  We generallyinclude  warranty  costs  associated  with our Offshore Oil and Gas Constructionsegment  as  a  component  of  our  total  contract  cost  estimate  to  satisfycontractual  requirements,  and  we  record  the  associated  expense  under thepercent-of-completion method of accounting for long-term construction contracts.In  addition,  we  make  specific provisions where we expect the actual warrantycosts to significantly exceed the accrued estimates.  Such provisions could havea material effect on our consolidated financial condition, results of operationsand  cash  flows.

The  following  summarizes  the  changes  in  our  accrued  warranty  expense:

We charge tocost  of  operations the costs of research and development unrelated to specificcontracts  as incurred.  For the six months ended June 30, 2009 and 2008 our netresearch  and  development  expense  included  in  cost  of  operations  totaledapproximately  $21.1  million  and  $18.8  million,  respectively.

Recently  Adopted  Accounting  Standards


In  May  2009,  the  FASB  issued  Statement  of  Financial Accounting Standards
("SFAS")  No.  165,  Subsequent  Events.  SFAS  No.  165  incorporates  specificaccounting and disclosure requirements for subsequent events into U.S. generallyaccepted  accounting  principles,  as  part  of  the  codification effort and inconjunction with SFAS Nos. 162 and 168. The adoption of these provisions did nothave  a  material  impact  on  our  consolidated  financial  statements.

In  April 2009, the FASB issued FASB Staff Position ("FSP") 141(R)-1, Accountingfor Assets Acquired and Liabilities Assumed in a Business Combination That Arisefrom  Contingencies.  FSP  141(R)-1 amends and clarifies SFAS No. 141 to addresssubsequent  measurement  and  accounting  for,  and  disclosure  of,  assets andliabilities arising from contingencies in a business combination.  On January 1,2009,  we  adopted  the  provisions  of  FSP  141(R)-1.  The  adoption  of theseprovisions  did  not  have  a  material  impact  on  our  consolidated financialstatements.

In  April  2009, the FASB issued FSP 107-1, Interim Disclosures about Fair Valueof  Financial Instruments. FSP 107-1 amends SFAS No. 107, Disclosures about FairValue  of  Financial  Instruments,  to  require  disclosures about fair value offinancial  instruments in financial statements. The adoption of these provisionsdid  not  have  a  material  impact  on  our  consolidated financial statements.

In  April  2008,  the FASB issued FSP 142-3, Determination of the Useful Life ofIntangible  Assets. FSP 142-3 requires companies estimating the useful life of arecognized  intangible asset to consider their historical experience in renewingor  extending  similar arrangements or, in the absence of historical experience,to  consider  assumptions  that  market participants would use about renewals orextensions as adjusted for the entity-specific factors in SFAS No. 142, Goodwilland  Other  Intangible  Assets. On January 1, 2009, we adopted the provisions ofFSP  142-3  for  the  determination of the useful life of intangible assets. Theadoption  of these provisions did not have a material impact on our consolidatedfinancial  statements.

In  March  2008,  the  FASB  issued  SFAS  No. 161, Disclosures About DerivativeInstruments  and  Hedging  Activities -  an amendment of FASB Statement No. 133.SFAS  No.  161  requires  enhanced  disclosures  about  derivative  and  hedgingactivities and is effective for financial statements issued for fiscal years andinterim  periods  beginning  after  November  15,  2008.  On January 1, 2009, weadopted  the  provisions  of  SFAS  No. 161 for our disclosures about derivativeinstruments  and  hedging  activities.  The adoption of these provisions did nothave  a  material  impact  on  our  consolidated  financial  statements.

In  December  2007,  the  FASB  issued SFAS No. 160, Noncontrolling Interests inConsolidated  Financial  Statements  - an Amendment of ARB No. 51.  SFAS No. 160establishes accounting and reporting standards pertaining to ownership interestsin  subsidiaries held by parties other than the parent, the amount of net incomeattributable  to  the  parent  and  to the noncontrolling interest, changes in aparent's  ownership  interest  and  the valuation of any retained noncontrollingequity  investment  when  a  subsidiary  is deconsolidated.  It also establishesdisclosure  requirements  that  clearly  identify  and  distinguish  between theinterests  of  the  parent  and  the interests of the noncontrolling owners.  OnJanuary  1,  2009,  we  adopted  the provisions of SFAS No. 160.  Noncontrollinginterest  has been presented as a separate component of stockholders' equity forthe  current  reporting  period  and  prior  comparative  reporting  period.

In  December  2007,  the  FASB  issued  SFAS  No.  141  (revised 2007), BusinessCombinations  ("SFAS  No.  141(R)"),  which  amends  SFAS  No.  141,  BusinessCombinations.  SFAS  No. 141(R) broadens the guidance of SFAS No. 141, extendingits  applicability  to  all  transactions and events in which one entity obtainscontrol  over  one  or  more  other  businesses.  It  broadens  the  fair  valuemeasurements  and  recognition  of  assets  acquired,  liabilities  assumed  andinterests  transferred  as  a result of business combinations.  It also providesdisclosure  requirements to enable users of the financial statements to evaluatethe  nature and financial effects of business combinations.  On January 1, 2009,we  adopted  the provisions of SFAS 141(R). The adoption of these provisions didnot  have  a  material  impact  on  our  consolidated  financial  statements.


 Accounting  Standards  Not  Yet  Adopted


In  June  2009,  the  FASB  issued  SFAS  No. 168, The FASB Accounting StandardsCodification  and  the  Hierarchy  of Generally Accepted Accounting Principles-aReplacement  of  FASB Statement No. 162.  SFAS No. 168 identifies the sources ofaccounting  principles and the framework for selecting the principles to be usedin the preparation of financial statements that are presented in conformity withgenerally  accepted  accounting  principles in the United States. This Statementwill  be  effective  for interim and annual reporting ending after September 15,2009.  We  do  not  expect  SFAS  No.  168  to  have  a  material  impact on ourconsolidated  financial  statements.

In  June  2009,  the FASB issued SFAS No. 167, Amendments to FASB InterpretationNo.  46(R).  SFAS No. 167 expands the scope of FASB Interpretation No. 46(R) andamends  guidance  for  assessing  and  analyzing  variable  interest entities asdefined in Interpretation No. 46(R). This Statement will be effective for fiscalyears beginning after November 15, 2009. We do not expect SFAS No. 167 to have amaterial  impact  on  our  consolidated  financial  statements.

Other than as described above, there have been no material changes to the recentpronouncements  discussed  in  our annual report on Form 10-K for the year ended
December  31,  2008.</us-gaap:OrganizationConsolidationAndPresentationOfFinancialStatementsDisclosureTextBlock>

Other  Financial  Instruments


We  used  the  following  methods  and  assumptions in estimating our fair valuedisclosures  for  our  other  financial  instruments,  as  follows:

Cash  and  cash  equivalents  and  restricted  cash  and  cash equivalents.  Thecarrying  amounts that we have reported in the accompanying consolidated balancesheets  for  cash  and cash equivalents and restricted cash and cash equivalentsapproximate  their  fair  values.

Long-term  and  short-term debt.  We base the fair values of debt instruments onquoted  market  prices.  Where quoted prices are not available, we base the fairvalues  on  the  present  value  of  future  cash  flows discounted at estimatedborrowing  rates  for  similar  debt instruments or on estimated prices based oncurrent  yields  for  debt  issues  of  similar  quality  and  terms.

The  estimated  fair  values  of  our  financial  instruments  are  as  follows:

Investigations  and  Litigation


With  regard  to  the  matter  of  Donald  F. Hall and Mary Ann Hall, et al., v.Babcock  &amp;  Wilcox  Company, et al. (the "Hall Litigation"), the parties enteredinto  the final settlement agreement described in our annual report on Form 10-Kfor  the year ended December 31, 2008 (our "2008 10-K"), and that settlement wasapproved  by  the  United  States  District  Court  for  the Western District ofPennsylvania  (the  "District  Court") in April 2009.  In May 2009, B&amp;W PGG paidapproximately  $52.5  million  pursuant  to  the  terms  of the final settlementagreement,  which  is  within  the  amount  we  have  accrued  for these claims.Additionally,  B&amp;W  PGG  and  Atlantic  Richfield  Company  ("ARCO"),  a  formerdefendant  in  the  Hall Litigation, entered into the final settlement agreementdescribed  in our 2008 10-K, relating to B&amp;W PGG's indemnity action against ARCOfor  any liability as a result of the Hall Litigation.  The indemnity settlementwas  also  approved  by the District Court in April 2009.  B&amp;W PGG and Babcock &amp;Wilcox  Technical  Services  Group,  Inc.,  formerly  known  as  B&amp;W  NuclearEnvironmental  Services,  Inc., have retained all insurance rights and intend tocontinue  to  pursue  recovery  from American Nuclear Insurers and mutual AtomicEnergy  Liability Underwriters ("ANI") to recover the amounts paid in settlementof  the  Hall Litigation in the matter of The Babcock &amp; Wilcox Company et al. v.American  Nuclear  Insurers  et  al.  (the  "ANI


Litigation"),  which  is  pending  before the Court of Common Pleas of AlleghenyCounty,  Pennsylvania.  A hearing in the ANI Litigation is set for September 14,2009  to  determine  the  legal  standard  to  be  applied  in determining ANI'sinsurance  coverage  obligations  with  respect  to  the  settlement of the HallLitigation.

The  three  separate  purported  class  action  complaints against MII, Bruce W.Wilkinson  (MII's former Chief Executive Officer and Chairman of the Board), andMichael  S. Taff (the Chief Financial Officer of MII) described in our 2008 10-Khave  been  consolidated. In April 2009, our motion to transfer the consolidatedcases  to  the  Southern  District  of  Texas  was granted. On May 22, 2009, theplaintiffs  filed  an amended consolidated complaint, which, among other things,added  Robert  A.  Deason  (JRMSA's  President and Chief Executive Officer) as adefendant  in  the  proceedings.  On  July 1, 2009, MII and the other defendantsfiled  a  motion to dismiss the complaint. The plaintiffs filed two responses tothe motion to dismiss: (1) a motion to convert the motion to dismiss to a motionfor  summary  judgment  and  granting the plaintiffs leave to conduct discovery,which  was  filed  on  July  10,  2009;  and  (2) an opposition to the motion todismiss,  which was filed on August 3, 2009.  MII and the other defendants fileda  response  to the plaintiffs' motion to convert on July 30, 2009 and intend tofile a reply to the plaintiffs' opposition to the motion to dismiss on or beforeAugust  24,  2009.  None  of  the  motions  have yet been set for hearing by theCourt.

With  regard  to the matter of Iroquois Falls Power Corp. v. Jacobs Canada Inc.,et  al.,  described  in  our  2008 10-K, Iroquois Falls Power Corp. ("Iroquois")filed  a notice of appeal of the decision of the Superior Court of Justice whichdenied  the  request  of  Iroquois  to amend its complaint and assert new claimsagainst  the defendants based on a breach of contractual warranty.  A hearing onthe appeal was held on June 2, 2009.  On June 25, 2009, the Court of Appeals forOntario reversed the decision of the Superior Court sending the case back to theSuperior Court for Iroquois to file an amended complaint on those new claims. Wehave  until  the  end  of  September,  2009 to seek leave to appeal the Court ofAppeals'  ruling.
         For a detailed description of these and other proceedings, please referto  Note  11 to the consolidated financial statements included in Part II of ourannual  report  on  Form  10-K  for  the  year  ended  December  31,  2008.

Some  of  our  contracts  contain  penalty  provisions  that  require  us to payliquidated  damages  if  we  are  responsible  for the failure to meet specifiedcontractual  milestone  dates  and the applicable customer asserts a claim underthese  provisions.  These  contracts  define  the  conditions  under  which  ourcustomers  may  make  claims against us for liquidated damages. In many cases inwhich  we  have  had  potential  exposure  for  liquidated damages, such damagesultimately  were not asserted by our customers.  As of June 30, 2009, we had notaccrued  for  approximately $111 million of potential liquidated damages that wecould  incur based upon our current expectations of the time to complete certainprojects  in  our  Offshore Oil and Gas Construction segment.  We do not believeany  claims  for  these  potential  liquidated  damages  are  probable  of beingassessed.  The  trigger  dates  for  the  majority of these potential liquidateddamages occurred during the fourth quarter of 2008. We are in active discussionswith our customers on the issues giving rise to delays in these projects, and webelieve  we  will  be  successful  in  obtaining schedule extensions that shouldresolve the potential for liquidated damages being assessed. However, we may notachieve  relief  on  some  or  all  of  the  issues. For certain projects in ourOffshore  Oil  and  Gas  Construction  segment,  we  have currently provided forapproximately $24 million in liquidated damages in our estimates of revenues andgross  profit,  of  which  approximately  $22 million has been recognized in ourfinancial  statements  to date, as we believe, based on the individual facts andcircumstances,  that  these  liquidated  damages  are  probable.</us-gaap:CommitmentsAndContingenciesDisclosureTextBlock>

  <!--DERIVATIVE FINANCIAL INSTRUMENTS-->
  <us-gaap:DerivativeInstrumentsAndHedgingActivitiesDisclosureTextBlock contextRef="c00004">NOTE  4  -  DERIVATIVE  FINANCIAL  INSTRUMENTS

Our  worldwide  operations give rise to exposure to market risks from changes inforeign  exchange  rates.  We  use  derivative  financial instruments (primarilyforeign  currency forward-exchange contracts) to reduce the impact of changes inforeign  exchange  rates  on  our  operating  results.  We use these instrumentsprimarily  to  hedge  our  exposure  associated  with  revenues  or costs on ourlong-term  contracts  and  other  cash  flow  exposures  that are denominated incurrencies  other than our operating entities' functional currencies.  We do nothold  or  issue financial instruments for trading or other speculative purposes.

We  enter  into  derivative financial instruments primarily as hedges of certainfirm purchase and sale commitments denominated in foreign currencies.  We recordthese  contracts at fair value on our consolidated balance sheets.  Depending onthe  hedge  designation  at the inception of the contract, the related gains andlosses  on these contracts are either deferred in stockholders' equity (deficit)as  a  component  of  accumulated  other  comprehensive  loss,  until  the


hedged  item  is  recognized  in  earnings, or offset against the change in fairvalue  of  the hedged firm commitment through earnings.  The ineffective portionof  a  derivative's  change  in  fair  value  and  any portion excluded from theassessment of effectiveness are immediately recognized in earnings.  The gain orloss  on  a derivative instrument not designated as a hedging instrument is alsoimmediately  recognized  in  earnings.  Gains and losses on derivative financialinstruments  that  require  immediate recognition are included as a component ofother  income  (expense)  -  net  in  our  consolidated  statements  of  income.

We  have  designated  all  of  our forward contracts as either cash flow or fairvalue  hedging  instruments.  The  hedged  risk  is  the  risk  of  changes  infunctional-currency-equivalent  cash  flows  attributable  to  changes  in  spotexchange  rates  of  forecasted  transactions related to long-term contracts andcertain  capital  expenditures.  We exclude from our assessment of effectivenessthe  portion  of  the  fair  value  of the forward contracts attributable to thedifference  between spot exchange rates and forward exchange rates.  At June 30,2009,  we  had  deferred  approximately  $9.1  million  of  net  losses on thesederivative  financial  instruments  in  accumulated other comprehensive loss. Ofthis  amount, we expect to recognize approximately $1.0 million of income in thenext  12  months.

At  June  30,  2009,  all  of  our derivative financial instruments consisted offoreign  currency  forward-exchange contracts. The notional value of our forwardcontracts  totaled $348.5 million at June 30, 2009, with maturities extending toDecember  2011.  These instruments consist primarily of contracts to purchase orsell  Euros  or  Canadian  Dollars.  The  fair  value of these contracts totaled($10.4)  million.  We  are  exposed  to  credit-related  losses  in the event ofnonperformance  by  counterparties to derivative financial instruments. However,when  possible,  we  enter  into International Swaps and Derivative Association,Inc.  agreements  with  our hedge counterparties to mitigate this risk.  We alsoattempt  to  mitigate  this risk by using major financial institutions with highcredit  ratings  and  limit  our exposure to hedge counterparties based on theircredit  ratings.  The  counterparties  to  all  of  our  derivative  financialinstruments  are  financial  institutions  included  in  our  credit  facilitiesdescribed in Note 6 to the consolidated financial statements included in Part IIof  our  annual  report  on  Form 10-K for the year ended December 31, 2008. Ourhedge  counterparties  have  the benefit of the same collateral arrangements andcovenants  as  described  under  these  facilities.
