NOTE 10—COMMITMENTS AND CONTINGENCIES

Previously Pending Litigation

The following discussion presents information relating to pending litigation discussed in Note 12—Commitments and Contingencies in our Annual Report on Form 10-K for the year ended December 31, 2012. There have been no material subsequent developments relating to these matters.

On or about August 23, 2004, a declaratory judgment action entitled Certain Underwriters at Lloyd’s London, et al. v. J. Ray McDermott, Inc. et al., was filed by certain underwriters at Lloyd’s, London and Threadneedle Insurance Company Limited (the “London Insurers”), in the 23^rd Judicial District Court, Assumption Parish, Louisiana, against MII, J. Ray McDermott, Inc. (“JRMI”) and two insurer defendants, Travelers and INA, seeking a declaration that the London Insurers have no obligation to indemnify MII and JRMI for certain bodily injury claims, including claims for asbestos and welding rod fume personal injury which have been filed by claimants in various state courts. Additionally, Travelers filed a cross-claim requesting a declaration of non-coverage in approximately 20 underlying matters. This proceeding was stayed by the Court on January 3, 2005. We do not believe an adverse judgment or material losses in this matter are probable, and, accordingly, we have not accrued any amounts relating to this contingency. Although there is a possibility of an adverse judgment, the amount or potential range of loss is not estimable at this time. The insurer-plaintiffs in this matter commenced this proceeding in a purported attempt to obtain a determination of insurance coverage obligations for occupational exposure and/or environmental matters for which we have given notice that we could potentially seek coverage. Because estimating losses would require, for every matter, known and unknown, on a case-by-case basis, anticipating what impact on coverage a judgment would have and a determination of an otherwise expected insured value, damages cannot be reasonably estimated.

On December 16, 2005, a proceeding entitled Antoine, et al. vs. J. Ray McDermott, Inc., et al. (“Antoine Suit”), was filed in the 24^th Judicial District Court, Jefferson Parish, Louisiana, by approximately 88 plaintiffs against approximately 215 defendants, including our subsidiaries formerly known as JRMI and Delta Hudson Engineering Corporation (“DHEC”), generally alleging injuries for exposure to asbestos, and unspecified chemicals, metals and noise while the plaintiffs were allegedly employed as Jones Act seamen. This case was dismissed by the Court on January 10, 2007, without prejudice to plaintiffs’ rights to refile their claims. On January 29, 2007, 21 plaintiffs from the dismissed Antoine Suit filed a matter entitled Boudreaux, et al. v. McDermott, Inc., et al. (the “Boudreaux Suit”), in the United States District Court for the Southern District of Texas, against JRMI and our subsidiary formerly known as McDermott Incorporated, and approximately 30 other employer defendants, alleging Jones Act seaman status and generally alleging exposure to welding fumes, solvents, dyes, industrial paints and noise. The Boudreaux Suit was transferred to the United States District Court for the Eastern District of Louisiana on May 2, 2007, which entered an order in September 2007 staying the matter until further order of the Court due to the bankruptcy filing of one of the co-defendants. Additionally, on January 29, 2007, another 43 plaintiffs from the dismissed Antoine Suit filed a matter entitled Antoine, et al. v. McDermott, Inc., et al. (the “New Antoine Suit”), in the 164^th Judicial District Court for Harris County, Texas, against JRMI, our subsidiary formerly known as McDermott Incorporated and approximately 65 other employer defendants and 42 maritime products defendants, alleging Jones Act seaman status and generally alleging personal injuries for exposure to asbestos and noise. On April 27, 2007, the District Court entered an order staying all activity and deadlines in the New Antoine Suit, other than service of process and answer/appearance dates, until further order of the Court. The New Antoine Suit plaintiffs filed a motion to lift the stay on February 20, 2009, which is pending before the Texas District Court. The plaintiffs seek monetary damages in an unspecified amount in both the Boudreaux Suit and New Antoine Suit cases and attorneys’ fees in the New Antoine Suit. We cannot reasonably estimate the extent of a potential judgment against us, if any, and we intend to vigorously defend these suits.

Other Litigation

On August 15, 2013 and August 20, 2013, two separate alleged purchasers of our common stock filed purported class action complaints against MII, Stephen M. Johnson and Perry L. Elders in the United States District Court for the Southern District of Texas. Both of the complaints seek to represent a class of purchasers of our stock between November 6, 2012 and August 5, 2013, and allege, among other things, that the defendants violated federal securities laws by disseminating materially false and misleading information and failing to disclose material information relating to weaknesses in project bidding and execution, poor risk evaluation, poor project management and losses in each of MII’s reporting segments. Each complaint seeks relief, including unspecified compensatory damages and an award for attorneys’ fees and other costs. On October 15, 2013, an alleged purchaser of common stock during the relevant time period filed a motion for consolidation of the two actions, appointment as lead plaintiff, and approval of his choice of lead counsel and liaison counsel. We believe the substantive allegations contained in the complaints are without merit, and we intend to defend against these claims vigorously.

Additionally, due to the nature of our business, we and our affiliates are, from time to time, involved in litigation or subject to disputes or claims related to our business activities, including, among other things:

•

performance- or warranty-related matters under our customer and supplier contracts and other business arrangements; and

•

workers’ compensation claims, Jones Act claims, occupational hazard claims, including asbestos-exposure claims, premises liability claims and other claims.

Based upon our prior experience, we do not expect that any of these other litigation proceedings, disputes and claims will have a material adverse effect on our consolidated financial condition, results of operations or cash flows; however, because of the inherent uncertainty of litigation and, in some cases, the availability and amount of potentially applicable insurance, we can provide no assurance that the resolution of any particular claim or proceeding to which we are a party will not have a material effect on our consolidated financial condition, results of operations or cash flows for the fiscal period in which that resolution occurs.

Environmental Matters

We have been identified as a potentially responsible party at various cleanup sites under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980, as amended (“CERCLA”). CERCLA and other environmental laws can impose liability for the entire cost of cleanup on any of the potentially responsible parties, regardless of fault or the lawfulness of the original conduct. Generally, however, where there are multiple responsible parties, a final allocation of costs is made based on the amount and type of wastes disposed of by each party and the number of financially viable parties, although this may not be the case with respect to any particular site. We have not been determined to be a major contributor of wastes to any of these sites. On the basis of our relative contribution of waste to each site, we expect our share of the ultimate liability for the various sites will not have a material adverse effect on our consolidated financial condition, results of operations or cash flows in any given year.

At September 30, 2013 we had no material amounts accrued for environmental reserves. Inherent in our estimates of reserves and recoveries are our expectations regarding the levels of contamination, remediation costs and recoverability from other parties, which may vary significantly as remediation activities progress. Accordingly, changes in estimates could result in material adjustments to our operating results, and the ultimate loss may differ materially from the amounts we have provided for in our consolidated financial statements.

Contracts Containing Liquidated Damages Provisions

Some of our contracts contain provisions that require us to pay liquidated damages if we are responsible for the failure to meet specified contractual milestone dates and the applicable customer asserts a claim under these provisions. These contracts define the conditions under which our customers may make claims against us for liquidated damages. In many cases in which we have historically had potential exposure for liquidated damages, such damages ultimately were not asserted by our customers. As of September 30, 2013, it is possible that we may incur liabilities for liquidated damages aggregating approximately $137.0 million, of which approximately $11.0 million has been recorded in our financial statements, based on our actual or projected failure to meet certain specified contractual milestone dates. The dates for which these potential liquidated damages could arise extend to June 2015. We believe we will be successful in obtaining schedule extensions or other customer-agreed changes that should resolve the potential for additional liquidated damages. Accordingly, we believe that no amounts for these potential liquidated damages in excess of the amounts currently reflected in our financial statements are probable of being paid by us. However, we may not achieve relief on some or all of the issues.

Contractual Obligations

At September 30, 2013, we had outstanding obligations related to our new vessel construction contracts on the LV 108 and DLV 2000 of $382.4 million in the aggregate, with $41.6 million, $136.5 million and $204.3 million due in the years ending December 31, 2013, 2014 and 2015, respectively.
