Item 1A. Risk Factors. Our business and the businesses of our subsidiaries face many risks and uncertainties. These risks and uncertainties could lead to events or circumstances that have a material adverse effect on our business, results of operations, cash flows, financial condition or equity and/or the business, results of operations, financial condition or equity of one or more of our subsidiaries. We have described below the most significant risks facing us and our subsidiaries. There may be additional risks that we do not yet know of or that we do not currently perceive to be as significant that may also impact our business or the businesses of our subsidiaries. You should carefully consider and evaluate all of the information included in this Report and any subsequent reports we may file with the Securities and Exchange Commission (“SEC”) and the information we make available to the public before investing in any securities issued by us. Our subsidiaries, CNA Financial Corporation, Diamond Offshore Drilling, Inc. and Boardwalk Pipeline Partners, LP, are public companies and file reports with the SEC. You are also cautioned to carefully review and consider the information contained in the reports filed by those subsidiaries with the SEC and the information they make available to the public before investing in any of their securities. Risks Related to Us and Our Subsidiary, CNA Financial Corporation If CNA determines that its recorded insurance reserves are insufficient to cover its estimated ultimate unpaid liability for claim and claim adjustment expenses, CNA may need to increase its insurance reserves which would result in a charge to CNA’s earnings. CNA maintains insurance reserves to cover its estimated ultimate unpaid liability for claim and claim adjustment expenses, including the estimated cost of the claims adjudication process, for reported and unreported claims. Insurance reserves are not an exact calculation of liability but instead are complex management estimates developed utilizing a variety of actuarial reserve estimation techniques as of a given reporting date. The reserve estimation process involves a high degree of judgment and variability and is subject to a number of factors which are highly uncertain. These variables can be affected by both changes in internal processes and external events. Key variables include claim severity, frequency of claims, mortality, morbidity, discount rates, inflation, claim handling policies and procedures, case reserving approach, underwriting and pricing policies, changes in the legal and regulatory environment and the lag time between the occurrence of an insured event and the time of its ultimate settlement. Mortality is the relative incidence of death. Morbidity is the frequency and severity of injury, illness, sickness and diseases contracted. There is generally a higher degree of variability in estimating required reserves for long-tail coverages, such as general liability and workers’ compensation, as they require a relatively longer period of time for claims to be reported and settled. The impact of changes in inflation and medical costs are also more pronounced for long-tail coverages due to the longer settlement period. CNA is also subject to the uncertain effects of emerging or potential claims and coverage issues that arise as industry practices and legal, judicial, social, economic and other environmental conditions change. These issues have had, and may continue to have, a negative effect on CNA’s business by either extending coverage beyond the original underwriting intent or by increasing the number or size of claims, resulting in further increases in CNA’s reserves. The effects of unforeseen emerging claim and coverage issues are extremely difficult to predict. Emerging or potential claim and coverage issues include, but are not limited to, uncertainty in future medical costs in workers’ compensation. In particular, medical cost inflation could be greater than expected due to new treatments, drugs and devices; increased health care utilization; and/or the future costs of health care facilities. In addition, the relationship between workers’ compensation and government and private health care providers could change, potentially shifting costs to workers’ compensation. In light of the many uncertainties associated with establishing the estimates and making the judgments necessary to establish reserve levels, CNA continually reviews and changes its reserve estimates in a regular and ongoing process as experience develops from the actual reporting and settlement of claims and as the legal, regulatory and economic environment evolves. If CNA’s recorded reserves are insufficient for any reason, the required increase in reserves would be recorded as a charge against earnings in the period in which reserves are determined to be insufficient. These charges could be substantial. CNA’s actual experience could vary from the key assumptions used to determine active life reserves for long term care policies. CNA’s active life reserves for long term care policies are based on CNA’s best estimate assumptions as of December 31, 2015 due to an unlocking at that date. Key assumptions include morbidity, persistency (the percentage of policies remaining in force), discount rate and future premium rate increases. These assumptions, which are critical bases for its reserve estimates are inherently uncertain. If actual experience varies from these assumptions or the future outlook for these assumptions changes, CNA may be required to increase its reserves. See the Long Term Care Policyholder Reserves portion of the Insurance Reserves section of MD&A in Item 7 for more information. Estimating future experience for long term care policies is highly uncertain because the required projection period is very long and there is limited historical and industry data available to CNA, as only a small portion of the long term care policies which have been written to date are in claims paying status. Morbidity and persistency trends, inclusive of mortality, can be volatile and may be negatively affected by many factors including, but not limited to, policyholder behavior, judicial decisions regarding policy terms, socioeconomic factors, cost of care inflation, changes in health trends and advances in medical care. A prolonged period during which interest rates remain at levels lower than those anticipated in CNA’s reserving would result in shortfalls in investment income on assets supporting CNA’s obligations under long term care policies, which may require changes to its reserves. This risk is more significant for CNA’s long term care products because the long potential duration of the policy obligations exceeds the duration of the supporting investment assets. Further, changes to the corporate tax code may also affect the rate at which CNA discounts its reserves. In addition, CNA may not receive regulatory approval for the level of premium rate increases it requests. Any adverse deviation between the level of future premium rate increases approved and the level included in CNA’s reserving assumptions may require an increase to its reserves. If CNA’s estimated reserves are insufficient for any reason, including changes in assumptions, the required increase in reserves would be recorded as a charge against earnings in the period in which reserves are determined to be insufficient. These charges could be substantial. Catastrophe and systemic losses are unpredictable and could result in material losses. Catastrophe losses are an inevitable part of CNA’s business. Various events can cause catastrophe losses. These events can be natural or man-made, and may include hurricanes, windstorms, earthquakes, hail, severe winter weather, fires, floods, riots, strikes, civil commotion, cyber attacks, pandemics and acts of terrorism. The frequency and severity of these catastrophe events are inherently unpredictable. In addition, longer-term natural catastrophe trends may be changing and new types of catastrophe losses may be developing due to climate change, a phenomenon that has been associated with extreme weather events linked to rising temperatures, and includes effects on global weather patterns, greenhouse gases, sea, land and air temperatures, sea levels, rain, hail and snow. The extent of CNA’s losses from catastrophes is a function of the total amount of its insured exposures in the affected areas, the frequency and severity of the events themselves, the level of reinsurance assumed and ceded, reinsurance reinstatement premiums and state residual market assessments, if any. It can take a long time for the ultimate cost of any catastrophe losses to CNA to be finally determined, as a multitude of factors contribute to such costs, including evaluation of general liability and pollution exposures, infrastructure disruption, business interruption and reinsurance collectibility. Reinsurance coverage for terrorism events is provided only in limited circumstances, especially in regard to “unconventional” terrorism acts, such as nuclear, biological, chemical or radiological attacks. As a result of the items discussed above, catastrophe losses are particularly difficult to estimate. Additionally, catastrophic events could cause CNA to exhaust its available reinsurance limits and could adversely affect the cost and availability of reinsurance. Claim frequency and severity for some lines of business can be correlated to an external factor such as economic activity, financial market volatility, increasing health care costs or changes in the legal or regulatory environment. Claim frequency and severity can also be correlated to insureds’ use of common business practices, equipment, vendors or software. This can result in multiple insured losses emanating out of the same underlying cause. In these instances, CNA may be subject to increased claim frequency and severity across multiple policies or lines of business concurrently. While CNA does not define such systemic losses as catastrophes for financial reporting purposes, they are similar to catastrophes in terms of the uncertainty and potential impact on its results. CNA has exposure related to A&EP claims, which could result in material losses. CNA’s property and casualty insurance subsidiaries have exposures related to A&EP claims. CNA’s experience has been that establishing claim and claim adjustment expense reserves for casualty coverages relating to A&EP claims is subject to uncertainties that are greater than those presented by other claims. Additionally, traditional actuarial methods and techniques employed to estimate the ultimate cost of claims for more traditional property and casualty exposures are less precise in estimating claim and claim adjustment expense reserves for A&EP. As a result, estimating the ultimate cost of both reported and unreported A&EP claims is subject to a higher degree of variability. On August 31, 2010, CNA completed a retroactive reinsurance transaction under which substantially all of its legacy A&EP liabilities were ceded to National Indemnity Company (“NICO”), a subsidiary of Berkshire Hathaway Inc., subject to an aggregate limit of $4.0 billion (“loss portfolio transfer” or “LPT”). The cumulative amount ceded under the loss portfolio transfer as of December 31, 2017 is $2.9 billion. If the other parties to the loss portfolio transfer do not fully perform their obligations, net losses incurred on A&EP claims covered by the loss portfolio transfer exceed the aggregate limit of $4.0 billion or CNA determines it has exposures to A&EP claims not covered by the loss portfolio transfer, CNA may need to increase its recorded net reserves which would result in a charge against earnings. These charges could be substantial. Additionally, if the A&EP claims exceed the limit of the loss portfolio transfer, CNA will need to assess whether to purchase additional limit or to reassume claim handling responsibility for A&EP claims from an affiliate of NICO. Any additional reinsurance premium or future claim handling costs would also reduce CNA’s earnings. CNA uses analytical models to assist its decision making in key areas such as pricing, reserving and capital modeling and may be adversely affected if actual results differ materially from the model outputs and related analyses. CNA uses various modeling techniques and data analytics (e.g., scenarios, predictive, stochastic and/or forecasting) to analyze and estimate exposures, loss trends and other risks associated with its assets and liabilities. This includes both proprietary and third party modeled outputs and related analyses to assist in decision-making related to underwriting, pricing, capital allocation, reserving, investing, reinsurance and catastrophe risk, among other things. CNA incorporates therein numerous assumptions and forecasts about the future level and variability of policyholder behavior, loss frequency and severity, interest rates, equity markets, inflation, capital requirements, and currency exchange rates, among others. The modeled outputs and related analyses from both proprietary and third parties are subject to various assumptions, uncertainties, model design errors and the inherent limitations of any statistical analysis, including those arising from the use of historical internal and industry data and assumptions. In addition, the effectiveness of any model can be degraded by operational risks including, but not limited to, the improper use of the model, including input errors, data errors and human error. As a result, actual results may differ materially from CNA’s modeled results. The profitability and financial condition of CNA substantially depends on the extent to which its actual experience is consistent with the assumptions CNA uses in its models and the ultimate model outputs. If, based upon these models or other factors, CNA misprices its products or fails to appropriately estimate the risks it is exposed to, its business, financial condition, results of operations or liquidity may be adversely affected. CNA faces intense competition in its industry. All aspects of the insurance industry are highly competitive and CNA must continuously allocate resources to refine and improve its insurance products and services to remain competitive. CNA competes with a large number of stock and mutual insurance companies and other entities, some of which may be larger or have greater financial or other resources than CNA does, for both distributors and customers. This includes agents and brokers who may increasingly compete with CNA to the extent that they continue to have direct access to providers of capital seeking exposure to insurance risk. Insurers compete on the basis of many factors, including products, price, services, ratings and financial strength. The competitor landscape has evolved substantially in recent years, with significant consolidation and new market entrants, resulting in increased pressures on CNA’s ability to remain competitive, particularly in implementing pricing that is both attractive to CNA’s customer base and risk appropriate to CNA. The property and casualty market is cyclical and has experienced periods characterized by relatively high levels of price competition, resulting in less restrictive underwriting standards and relatively low premium rates, followed by periods of relatively lower levels of competition, more selective underwriting standards and relatively high premium rates. During periods in which price competition is high, CNA may lose business to competitors offering competitive insurance products at lower prices. As a result, CNA’s premium levels and expense ratio could be materially adversely impacted. CNA markets its insurance products worldwide primarily through independent insurance agents and insurance brokers, who also promote and distribute the products of CNA’s competitors. Any change in CNA’s relationships with its distribution network agents and brokers, including as a result of consolidation and their increased promotion and distribution of CNA’s competitors’ products, could adversely affect CNA’s ability to sell its products. As a result, CNA’s business volume and results of operations could be materially adversely impacted. CNA may be adversely affected by technological changes or disruptions in the insurance marketplace. Technological changes in the way insurance transactions are completed in the marketplace, and CNA’s ability to react effectively to such change, may present significant competitive risks. For example, more insurers are utilizing “big data” analytics to make underwriting and other decisions that impact product design and pricing. If such utilization is more effective than how CNA uses similar data and information, CNA will be at a competitive disadvantage. There can be no assurance that CNA will continue to compete effectively with its industry peers due to technological changes; accordingly this may have a material adverse effect on CNA’s business and results of operations. In addition, agents and brokers, technology companies or other third parties may create alternate distribution channels for commercial business that may adversely impact product differentiation and pricing. For example, they may create a digitally enabled distribution channel that may adversely impact CNA’s competitive position. CNA’s efforts or the efforts of agents and brokers with respect to new products or alternate distribution channels, as well as changes in the way agents and brokers utilize greater levels of data and technology, could adversely impact CNA’s business relationships with independent agents and brokers who currently market its products, resulting in a lower volume and/or profitability of business generated from these sources. CNA may not be able to obtain sufficient reinsurance at a cost it deems acceptable, which could result in increased exposure to risk or a decrease in CNA’s underwriting commitments. CNA purchases reinsurance to help manage its exposure to risk. Under CNA’s ceded reinsurance arrangements, another insurer assumes a specified portion of CNA’s exposure in exchange for a specified portion of policy premiums. Market conditions determine the availability and cost of the reinsurance protection CNA purchases, which affects the level of its business and profitability, as well as the level and types of risk CNA retains. If CNA is unable to obtain sufficient reinsurance at a cost it deems acceptable, CNA may have increased exposure to risk. Alternatively, CNA may be unwilling to bear the increased risk and would reduce the level of its underwriting commitments. CNA may not be able to collect amounts owed to it by reinsurers, which could result in higher net incurred losses. CNA has significant amounts recoverable from reinsurers which are reported as receivables on its balance sheets and are estimated in a manner consistent with claim and claim adjustment expense reserves or future policy benefit reserves. The ceding of insurance does not, however, discharge CNA’s primary liability for claims. As a result, CNA is subject to credit risk relating to its ability to recover amounts due from reinsurers. Certain of CNA’s reinsurance carriers have experienced credit downgrades by rating agencies within the term of CNA’s contractual relationship, which indicates an increase in the likelihood that CNA will not be able to recover amounts due. In addition, reinsurers could dispute amounts which CNA believes are due to it. If the amounts due from reinsurers that CNA is able to collect are less than the amount recorded by CNA with respect to such amounts due, its incurred losses will be higher. CNA may not be able to collect amounts owed to it by policyholders who hold deductible policies and/or who purchase retrospectively rated policies, which could result in higher net incurred losses. A portion of CNA’s business is written under deductible policies. Under these policies, CNA is obligated to pay the related insurance claims and is reimbursed by the policyholder to the extent of the deductible, which may be significant. Moreover, certain policyholders purchase retrospectively rated workers’ compensation policies (i.e., policies in which premiums are adjusted after the policy period based on the actual loss experience of the policyholder during the policy period). Retrospectively rated policies expose CNA to additional credit risk to the extent that the adjusted premium is greater than the original premium, which may be significant. As a result, CNA is exposed to policyholder credit risk. If the amounts due from policyholders that CNA is able to collect are less than the amounts recorded with respect to such amounts due, CNA’s net incurred losses will be higher. CNA may incur significant realized and unrealized investment losses and volatility in net investment income arising from changes in the financial markets. CNA’s investment portfolio is exposed to various risks, such as interest rate, credit spread, issuer default, equity prices and foreign currency, which are unpredictable. Financial markets are highly sensitive to changes in economic conditions, monetary policies, tax policies, domestic and international geopolitical issues and many other factors. Changes in financial markets including fluctuations in interest rates, credit, equity prices and foreign currency prices, and many other factors beyond CNA’s control can adversely affect the value of its investments, the realization of investment income and the rate at which it discounts certain liabilities. CNA has significant holdings in fixed income investments that are sensitive to changes in interest rates. A decline in interest rates may reduce the returns earned on new fixed income investments, thereby reducing CNA’s net investment income, while an increase in interest rates may reduce the value of its existing fixed income investments. The value of CNA’s fixed income investments is also subject to risk that certain investments may default or become impaired due to deterioration in the financial condition of issuers of the investments CNA holds or in the underlying collateral of the security. Any such impairments which CNA deems to be other-than-temporary would result in a charge to earnings. In addition, CNA invests a portion of its assets in limited partnerships which are subject to greater market volatility than its fixed income investments. Limited partnership investments generally provide a lower level of liquidity than fixed maturity or equity investments, which may also limit CNA’s ability to withdraw assets. Further, CNA holds a portfolio of commercial mortgage loans. CNA is subject to risk related to the recoverability of loan balances, which is influenced by declines in the estimated cash flows from underlying property leases, fair value of collateral and creditworthiness of tenants of the underlying properties, where lease payments directly service the loan. Collecting amounts from borrowers that are less than the amounts recorded would result in a charge to earnings. As a result of these factors, CNA may not earn an adequate return on its investments, may be required to write down the value of its investments and may incur losses on the disposition of its investments. Inability to detect and prevent significant employee or third party service provider misconduct or inadvertent errors and omissions could result in a material adverse effect on CNA’s operations. CNA may incur losses which arise from employees or third party service providers engaging in intentional misconduct, fraud, errors and omissions, failure to comply with internal guidelines, including with respect to underwriting authority, or failure to comply with regulatory requirements. CNA’s controls may not be able to detect all possible circumstances of employee and third party service provider non-compliant activity and the internal structures in place to prevent this activity may not be effective in all cases. Any losses relating to such non-compliant activity could adversely affect CNA’s results of operations. CNA is subject to capital adequacy requirements and, if it is unable to maintain or raise sufficient capital to meet these requirements, regulatory agencies may restrict or prohibit CNA from operating its business. Insurance companies such as CNA are subject to capital adequacy standards set by regulators to help identify companies that merit further regulatory attention. These standards apply specified risk factors to various asset, premium and reserve components of CNA’s legal entity statutory basis of accounting financial statements. Current rules, including those promulgated by insurance regulators and specialized markets such as Lloyd’s, require companies to maintain statutory capital and surplus at a specified minimum level determined using the applicable jurisdiction’s regulatory capital adequacy formula. If CNA does not meet these minimum requirements, CNA may be restricted or prohibited from operating its business in the applicable jurisdictions and specialized markets. If CNA is required to record a material charge against earnings in connection with a change in estimated insurance reserves, the occurrence of a catastrophic event or if it incurs significant losses related to its investment portfolio, which severely deteriorates its capital position, CNA may violate these minimum capital adequacy requirements unless it is able to raise sufficient additional capital. CNA may be limited in its ability to raise significant amounts of capital on favorable terms or at all. Globally, insurance regulators are working cooperatively to develop a common framework for the supervision of internationally active insurance groups. Finalization and adoption of this framework could increase CNA’s prescribed capital requirement, the level at which regulatory scrutiny intensifies, as well as significantly increase its cost of regulatory compliance. CNA’s insurance subsidiaries, upon whom CNA depends for dividends in order to fund its corporate obligations, are limited by insurance regulators in their ability to pay dividends. CNA is a holding company and is dependent upon dividends, loans and other sources of cash from its subsidiaries in order to meet its obligations. Ordinary dividend payments or dividends that do not require prior approval by the insurance subsidiaries’ domiciliary insurance regulator are generally limited to amounts determined by formulas that vary by jurisdiction. If CNA is restricted from paying or receiving intercompany dividends, by regulatory rule or otherwise, CNA may not be able to fund its corporate obligations and debt service requirements from available cash. As a result, CNA would need to look to other sources of capital which may be more expensive or may not be available at all. Rating agencies may downgrade their ratings of CNA and thereby adversely affect its ability to write insurance at competitive rates or at all. Ratings are an important factor in establishing the competitive position of insurance companies. CNA’s insurance company subsidiaries, as well as CNA’s public debt, are rated by rating agencies, including, A.M. Best Company (“A.M. Best”), Moody’s Investors Service, Inc. (“Moody’s”) and S&P Global Ratings (“S&P”). Ratings reflect the rating agency’s opinions of an insurance company’s or insurance holding company’s financial strength, capital adequacy, enterprise risk management practices, operating performance, strategic position and ability to meet its obligations to policyholders and debt holders. The rating agencies may take action to lower CNA’s ratings in the future as a result of any significant financial loss or possible changes in the methodology or criteria applied by the rating agencies. The severity of the impact on CNA’s business is dependent on the level of downgrade and, for certain products, which rating agency takes the rating action. Among the adverse effects in the event of such downgrades would be the inability to obtain a material volume of business from certain major insurance brokers, the inability to sell a material volume of CNA’s insurance products to certain markets and the required collateralization of certain future payment obligations or reserves. In addition, it is possible that a significant lowering of our corporate debt ratings by certain of the rating agencies could result in an adverse affect on CNA’s ratings, independent of any change in CNA’s circumstances. CNA is subject to extensive regulations that restrict its ability to do business and generate revenues. The insurance industry is subject to comprehensive and detailed regulation and supervision. Most insurance regulations are designed to protect the interests of CNA’s policyholders and third-party claimants rather than its investors. Each jurisdiction in which CNA does business has established supervisory agencies that regulate the manner in which CNA conducts its business. Any changes in regulation could impose significant burdens on CNA. In addition, the Lloyd’s marketplace sets rules under which its members, including CNA’s Hardy syndicate, operate. These rules and regulations relate to, among other things, the standards of solvency (including risk-based capital measures), government-supported backstops for certain catastrophic events (including terrorism), investment restrictions, accounting and reporting methodology, establishment of reserves and potential assessments of funds to settle covered claims against impaired, insolvent or failed private or quasi-governmental insurers. Regulatory powers also extend to premium rate regulations which require that rates not be excessive, inadequate or unfairly discriminatory. State jurisdictions ensure compliance with such regulations through market conduct exams, which may result in losses to the extent non-compliance is ascertained, either as a result of failure to document transactions properly or failure to comply with internal guidelines, or otherwise. CNA may also be required by the jurisdictions in which it does business to provide coverage to persons who would not otherwise be considered eligible or restrict CNA from withdrawing from unprofitable lines of business or unprofitable market areas. Each jurisdiction dictates the types of insurance and the level of coverage that must be provided to such involuntary risks. CNA’s share of these involuntary risks is mandatory and generally a function of its respective share of the voluntary market by line of insurance in each jurisdiction. The United Kingdom’s expected exit from the European Union is expected to increase the complexity and cost of regulatory compliance of CNA’s European business. In 2016, the U.K. held a referendum in which voters approved an exit from the E.U., commonly referred to as “Brexit.” As a result of the referendum, in 2017 the British government formally commenced the process to leave the E.U. and began negotiating the terms of treaties that will govern the U.K.’s future relationship with the E.U. Although the terms of any future treaties are unknown, CNA believes changes in its international operating platform will be required to allow CNA to continue to write business in the E.U. after the completion of Brexit. Therefore, CNA has begun the process of establishing a new European subsidiary in Luxembourg. As a result of these changes, the complexity and cost of regulatory compliance of CNA’s European business is likely to increase. Risks Related to Us and Our Subsidiary, Diamond Offshore Drilling, Inc. The worldwide demand for Diamond Offshore’s drilling services has historically been dependent on the price of oil and has declined significantly as a result of the decline in oil prices, and demand has continued to be depressed in 2017. Demand for Diamond Offshore’s drilling services depends in large part upon the oil and natural gas industry’s offshore exploration and production activity and expenditure levels, which are directly affected by oil and gas prices and market expectations of potential changes in oil and gas prices. Commencing in the second half of 2014, oil prices declined significantly, resulting in a sharp decline in the demand for offshore drilling services, including services that Diamond Offshore provides, and adversely affecting Diamond Offshore’s operations and cash flows in 2015, 2016 and 2017, compared to previous years. Any prolonged continuation of low oil prices would have a material adverse effect on many of Diamond Offshore’s customers and, therefore, on demand for its services and on its business. Oil prices have been, and are expected to continue to be, volatile and are affected by numerous factors beyond Diamond Offshore’s control. An increase in the price of oil and gas will not necessarily result in an increase in offshore drilling activity or an increase in the market demand for Diamond Offshore’s rigs, although, historically, higher commodity prices have generally resulted in increases in offshore drilling projects. The timing of commitment to offshore activity in a cycle depends on project deployment times, reserve replacement needs, availability of capital and alternative options for resource development. Timing can also be affected by availability, access to, and cost of equipment to perform work. Diamond Offshore’s business depends on the level of activity in the offshore oil and gas industry, which has been cyclical and is significantly affected by many factors outside of its control. Demand for Diamond Offshore’s drilling services depends upon the level of offshore oil and gas exploration, development and production in markets worldwide, and those activities depend in large part on oil and gas prices, worldwide demand for oil and gas and a variety of political and economic factors. The level of offshore drilling activity is adversely affected when operators reduce or defer new investment in offshore projects, reduce or suspend their drilling budgets or reallocate their drilling budgets away from offshore drilling in favor of other priorities, such as shale or other land-based projects. As a result, Diamond Offshore’s business and the oil and gas industry in general are subject to cyclical fluctuations. As a result of the cyclical fluctuations in the market, there have been periods of lower demand, excess rig supply and lower dayrates, followed by periods of higher demand, shorter rig supply and higher dayrates. Diamond Offshore cannot predict the timing or duration of such fluctuations. Periods of lower demand or excess rig supply, which have occurred in the recent past and are continuing, intensify the competition in the industry and often result in periods of lower utilization and lower dayrates. During these periods, Diamond Offshore’s rigs may not obtain contracts for future work and may be idle for long periods of time or may be able to obtain work only under contracts with lower dayrates or less favorable terms. Additionally, prolonged periods of low utilization and dayrates could also result in the recognition of further impairment charges on certain of Diamond Offshore’s drilling rigs if future cash flow estimates, based upon information available to management at the time, indicate that the carrying value of these rigs may not be recoverable. Diamond Offshore’s industry is highly competitive, with oversupply and intense price competition. The offshore contract drilling industry is highly competitive with numerous industry participants. Some of Diamond Offshore’s competitors may be larger companies, have larger or more technologically advanced fleets and have greater financial or other resources than it does. The drilling industry has experienced consolidation in the past and may experience additional consolidation, which could create additional large competitors. Drilling contracts are traditionally awarded on a competitive bid basis. Price is typically the primary factor in determining which qualified contractor is awarded a job. New rig construction and upgrades of existing drilling rigs, cancelation or termination of drilling contracts and established rigs coming off contract have contributed to the current oversupply of drilling rigs, intensifying price competition. Diamond Offshore can provide no assurance that its drilling contracts will not be terminated early or that its current backlog of contract drilling revenue will be ultimately realized. Currently, Diamond Offshore’s customers may terminate their drilling contracts under certain circumstances, such as the destruction or loss of a drilling rig or if Diamond Offshore suspends drilling operations for a specified period of time as a result of a breakdown of major equipment, excessive downtime for repairs, failure to meet minimum performance criteria (including customer acceptance testing) or, in some cases, due to other events beyond the control of either party. In addition, some of Diamond Offshore’s drilling contracts permit the customer to terminate the contract after specified notice periods, often by tendering contractually specified termination amounts, which may not fully compensate Diamond Offshore for the loss of the contract. During depressed market conditions, such as those currently in effect, certain customers have utilized such contract clauses to seek to renegotiate or terminate a drilling contract or claim that Diamond Offshore has breached provisions of its drilling contracts in order to avoid their obligations to Diamond Offshore under circumstances where Diamond Offshore believes it is in compliance with the contracts. Additionally, because of depressed commodity prices, restricted credit markets, economic downturns, changes in priorities or strategy or other factors beyond Diamond Offshore’s control, a customer may no longer want or need a rig that is currently under contract or may be able to obtain a comparable rig at a lower dayrate. For these reasons, customers may seek to renegotiate the terms of Diamond Offshore’s existing drilling contracts, terminate their contracts without justification or repudiate or otherwise fail to perform their obligations under the contracts. As a result of such contract renegotiations or terminations, Diamond Offshore’s contract backlog may be adversely impacted, it might not recover any compensation (or any recovery it obtains may not fully compensate it for the loss of the contract) and it may be required to idle one or more rigs for an extended period of time. Diamond Offshore may not be able to renew or replace expiring contracts for its rigs. As of the date of this Report, all of Diamond Offshore’s current customer contracts will expire between 2018 and 2020. Diamond Offshore’s ability to renew or replace expiring contracts or obtain new contracts, and the terms of any such contracts, will depend on various factors, including market conditions and the specific needs of its customers at such times. Given the historically cyclical and highly competitive nature of the industry, Diamond Offshore may not be able to renew or replace the contracts or it may be required to renew or replace expiring contracts or obtain new contracts at dayrates that are below, and likely substantially below, existing dayrates, or that have terms that are less favorable than existing contracts. Moreover, Diamond Offshore may be unable to secure contracts for these rigs. Failure to secure contracts for a rig may result in a decision to cold stack the rig, which puts the rig at risk for impairment and may competitively disadvantage the rig as customers during the most recent market downturn have expressed a preference for ready or “hot” stacked rigs over cold-stacked rigs. Diamond Offshore’s contract drilling expense includes fixed costs that will not decline in proportion to decreases in rig utilization and dayrates. Diamond Offshore’s contract drilling expense includes all direct and indirect costs associated with the operation, maintenance and support of its drilling equipment, which is often not affected by changes in dayrates and utilization. During periods of reduced revenue and/or activity, certain of Diamond Offshore’s fixed costs will not decline and often it may incur additional operating costs, such as fuel and catering costs, for which it is generally reimbursed by the customer when a rig is under contract. During times of reduced utilization, reductions in costs may not be immediate as Diamond Offshore may incur additional costs associated with cold stacking a rig (particularly if Diamond Offshore cold stacks a newer rig, such as a drillship or other DP semisubmersible rig, for which cold stacking costs are typically substantially higher than for an older floater rig), or it may not be able to fully reduce the cost of its support operations in a particular geographic region due to the need to support the remaining drilling rigs in that region. Accordingly, a decline in revenue due to lower dayrates and/or utilization may not be offset by a corresponding decrease in contract drilling expense. Contracts for Diamond Offshore’s drilling rigs are generally fixed dayrate contracts, and increases in Diamond Offshore’s operating costs could adversely affect the profitability of those contracts. Diamond Offshore’s contracts for its drilling rigs generally provide for the payment of an agreed dayrate per rig operating day, although some contracts do provide for a limited escalation in dayrate due to increased operating costs it incurs on the project. Many of Diamond Offshore’s operating costs, such as labor costs, are unpredictable and may fluctuate based on events beyond its control. In addition, equipment repair and maintenance expenses vary depending on the type of activity the rig is performing, the age and condition of the equipment and general market factors impacting relevant parts, components and services. The gross margin that Diamond Offshore realizes on these fixed dayrate contracts will fluctuate based on variations in its operating costs over the terms of the contracts. In addition, for contracts with dayrate escalation clauses, Diamond Offshore may not be able to fully recover increased or unforeseen costs from its customers. Diamond Offshore is subject to extensive domestic and international laws and regulations that could significantly limit its business activities and revenues and increase its costs. Certain countries are subject to restrictions, sanctions and embargoes imposed by the United States government or other governmental or international authorities. These restrictions, sanctions and embargoes may prohibit or limit Diamond Offshore from participating in certain business activities in those countries. Diamond Offshore’s operations are also subject to numerous local, state and federal laws and regulations in the United States and in foreign jurisdictions concerning the containment and disposal of hazardous materials, the remediation of contaminated properties and the protection of the environment. Laws and regulations protecting the environment have become increasingly stringent, and may in some cases impose “strict liability,” rendering a person liable for environmental damage without regard to negligence or fault on the part of that person. Failure to comply with such laws and regulations could subject Diamond Offshore to civil or criminal enforcement action, for which it may not receive contractual indemnification or have insurance coverage, and could result in the issuance of injunctions restricting some or all of Diamond Offshore’s activities in the affected areas. Diamond Offshore may be required to make significant expenditures for additional capital equipment or inspections and recertifications to comply with existing or new governmental laws and regulations. It is also possible that these laws and regulations may, in the future, add significantly to Diamond Offshore’s operating costs or result in a reduction in revenues associated with downtime required to install such equipment, or may otherwise significantly limit drilling activity. In addition, Diamond Offshore’s business is negatively impacted when it performs certain regulatory inspections, which Diamond Offshore refers to as a special survey, that are due every five years for most of its rigs. The inspection interval for Diamond Offshore’s North Sea rigs is two and one half years. These special surveys are generally performed in a shipyard and require scheduled downtime, which can negatively impact operating revenue. Operating expenses increase as a result of these special surveys due to the cost to mobilize the rigs to a shipyard, and inspection, repair and maintenance costs. Repair and maintenance activities may result from the special survey or may have been previously planned to take place during this mandatory downtime. The number of rigs undergoing a special survey will vary from year to year, as well as from quarter to quarter. Diamond Offshore’s business may also be negatively impacted by intermediate surveys, which are performed at interim periods between special surveys. Although an intermediate survey normally does not require shipyard time, the survey may require some downtime for the rig. Diamond Offshore can provide no assurance as to the exact timing and/or duration of downtime associated with regulatory inspections, planned rig mobilizations and other shipyard projects. In addition, the offshore drilling industry is dependent on demand for services from the oil and gas exploration industry and, accordingly, can be affected by changes in tax and other laws relating to the energy business generally. Governments in some countries are increasingly active in regulating and controlling the ownership of concessions, the exploration for oil and gas and other aspects of the oil and gas industry. The modification of existing laws or regulations or the adoption of new laws or regulations curtailing exploratory or developmental drilling for oil and gas for economic, environmental or other reasons could limit drilling opportunities. Diamond Offshore’s business involves numerous operating hazards which could expose it to significant losses and significant damage claims. Diamond Offshore is not fully insured against all of these risks and its contractual indemnity provisions may not fully protect Diamond Offshore. Diamond Offshore’s operations are subject to the significant hazards inherent in drilling for oil and gas offshore, such as blowouts, reservoir damage, loss of production, loss of well control, unstable or faulty sea floor conditions, fires and natural disasters such as hurricanes. The occurrence of any of these types of events could result in the suspension of drilling operations, damage to or destruction of the equipment involved and injury or death to rig personnel and damage to producing or potentially productive oil and gas formations, oil spillage, oil leaks, well blowouts and extensive uncontrolled fires, any of which could cause significant environmental damage. In addition, offshore drilling operations are subject to marine hazards, including capsizing, grounding, collision and loss or damage from severe weather. Operations also may be suspended because of machinery breakdowns, abnormal drilling conditions, failure of suppliers or subcontractors to perform or supply goods or services or personnel shortages. Any of the foregoing events could result in significant damage or loss to Diamond Offshore’s properties and assets or the properties and assets of others, injury or death to rig personnel or others, significant loss of revenues and significant damage claims against Diamond Offshore. Diamond Offshore’s drilling contracts with its customers provide for varying levels of indemnity and allocation of liabilities between its customers and Diamond Offshore with respect to the hazards and risks inherent in, and damages or losses arising out of, its operations, and Diamond Offshore may not be fully protected. Diamond Offshore’s contracts are individually negotiated, and the levels of indemnity and allocation of liabilities in them can vary from contract to contract depending on market conditions, particular customer requirements and other factors existing at the time a contract is negotiated. Additionally, the enforceability of indemnification provisions in Diamond Offshore’s contracts may be limited or prohibited by applicable law or such provisions may not be enforced by courts having jurisdiction, and Diamond Offshore could be held liable for substantial losses or damages and for fines and penalties imposed by regulatory authorities. The indemnification provisions in Diamond Offshore’s contracts may be subject to differing interpretations, and the laws or courts of certain jurisdictions may enforce such provisions while other laws or courts may find them to be unenforceable. The law with respect to the enforceability of indemnities varies from jurisdiction to jurisdiction and is unsettled under certain laws that are applicable to Diamond Offshore’s contracts. There can be no assurance that Diamond Offshore’s contracts with its customers, suppliers and subcontractors will fully protect it against all hazards and risks inherent in its operations. There can also be no assurance that those parties with contractual obligations to indemnify Diamond Offshore will be financially able to do so or will otherwise honor their contractual obligations. Diamond Offshore maintains liability insurance, which generally includes coverage for environmental damage; however, because of contractual provisions and policy limits, Diamond Offshore’s insurance coverage may not adequately cover its losses and claim costs. In addition, certain risks and contingencies related to pollution, reservoir damage and environmental risks are generally not fully insurable. Also, Diamond Offshore does not typically purchase loss-of-hire insurance to cover lost revenues when a rig is unable to work. There can be no assurance that Diamond Offshore will continue to carry the insurance it currently maintains, that its insurance will cover all types of losses or that it will be able to maintain adequate insurance in the future at rates it considers to be reasonable or that Diamond Offshore will be able to obtain insurance against some risks. If an accident or other event occurs that exceeds Diamond Offshore’s insurance coverage limits or is not an insurable event under its insurance policies, or is not fully covered by contractual indemnity, it could result in significant loss to Diamond Offshore. Significant portions of Diamond Offshore’s operations are conducted outside the United States and involve additional risks not associated with United States domestic operations. Diamond Offshore’s operations outside the United States accounted for approximately 58%, 66% and 79% of its total consolidated revenues for 2017, 2016 and 2015 and include, or have included, operations in South America, Australia and Southeast Asia, Europe, East and West Africa, the Mediterranean and Mexico. Because Diamond Offshore operates in various regions throughout the world, it is exposed to a variety of risks inherent in international operations, including risks of war or conflicts, political and economic instability and disruption, civil disturbance, acts of piracy, terrorism or other assaults on property or personnel, corruption, possible economic and legal sanctions (such as possible restrictions against countries that the U.S. government may consider to be state sponsors of terrorism), changes in global monetary and trade policies, laws and regulations, fluctuations in currency exchange rates, restrictions on currency exchange, controls over the repatriation of income or capital and other risks. Diamond Offshore may not have insurance coverage for these risks, or it may not be able to obtain adequate insurance coverage for such events at reasonable rates. Diamond Offshore’s operations may become restricted, disrupted or prohibited in any country in which any of these risks occur. Diamond Offshore is also subject to the regulations of the U.S. Treasury Department’s Office of Foreign Assets Control and other U.S. laws and regulations governing its international operations in addition to domestic and international anti-bribery laws and sanctions, trade laws and regulations, customs laws and regulations and other restrictions imposed by other governmental or international authorities. In addition, international contract drilling operations are subject to various laws and regulations in countries in which Diamond Offshore operates, including laws and regulations relating to the equipping and operation of drilling rigs, import-export quotas or other trade barriers, repatriation of foreign earnings or capital, oil and gas exploration and development, local content requirements, taxation of offshore earnings and earnings of expatriate personnel and use and compensation of local employees and suppliers by foreign contractors. Diamond Offshore’s consolidated effective income tax rate may vary substantially from one reporting period to another. Diamond Offshore’s consolidated effective income tax rate is impacted by the mix between its domestic and international pre-tax earnings or losses, as well as the mix of the international tax jurisdictions in which it operates. Diamond Offshore cannot provide any assurances as to what its consolidated effective income tax rate will be in the future due to, among other factors, uncertainty regarding the nature and extent of its business activities in any particular jurisdiction in the future and the tax laws of such jurisdictions, as well as potential changes in U.S. and foreign tax laws, regulations or treaties or the interpretation or enforcement thereof, changes in the administrative practices and precedents of tax authorities or any reclassification or other matter (such as changes in applicable accounting rules) that increases the amounts Diamond Offshore has provided for income taxes or deferred tax assets and liabilities in its consolidated financial statements. This variability may cause its consolidated effective income tax rate to vary substantially from one reporting period to another. Diamond Offshore may be required to accrue additional tax liability on certain of its foreign earnings. Certain of Diamond Offshore’s international rigs are owned and operated, directly or indirectly, by Diamond Foreign Asset Company (“DFAC”), a Cayman Islands subsidiary that it owns. It is Diamond Offshore’s intention to continue to indefinitely reinvest the earnings of DFAC and its foreign subsidiaries to finance its foreign activities. Diamond Offshore does not expect to provide for U.S. taxes on any earnings generated by DFAC and its foreign subsidiaries, except to the extent that these earnings are immediately subjected to U.S. federal income tax, such as under the Tax Cut and Jobs Act of 2017 (the “Tax Act”). Should a future distribution be made from any unremitted earnings of this subsidiary, Diamond Offshore may be required to record additional U.S. income taxes and/or withholding taxes in certain jurisdictions; however, it is not practical to estimate this potential liability. Diamond Offshore’s debt levels may limit its liquidity and flexibility in obtaining additional financing and in pursuing other business opportunities. Diamond Offshore’s business is highly capital intensive and dependent on having sufficient cash flow and/or available sources of financing in order to fund its capital expenditure requirements. As of December 31, 2017, Diamond Offshore had outstanding $2 billion of senior notes, maturing at various times from 2023 through 2043. As of February 9, 2018, Diamond Offshore had no outstanding borrowings and $1.5 billion available under its revolving credit facility to meet its short term liquidity requirements. Diamond Offshore may incur additional indebtedness in the future and borrow from time to time under its revolving credit facility to fund working capital or other needs, subject to compliance with its covenants. Diamond Offshore’s ability to meet its debt service obligations is dependent upon its future performance, which is subject to general economic conditions, industry cycles and financial, business and other factors affecting its operations, many of which are beyond its control. High levels of indebtedness could have negative consequences to Diamond Offshore, including: • it may have difficulty satisfying its obligations with respect to its outstanding debt; • it may have difficulty obtaining financing in the future for working capital, capital expenditures, acquisitions or other purposes; • it may need to use a substantial portion of available cash flow from operations to pay interest and principal on its debt, which would reduce the amount of money available to fund working capital requirements, capital expenditures, the payment of dividends and other general corporate or business activities; • vulnerability to the effects of general economic downturns, adverse industry conditions and adverse operating results could increase; • flexibility in planning for, or reacting to, changes in its business and in its industry in general could be limited; • it may not have the ability to pursue business opportunities that become available; • the amount of debt and the amount it must pay to service its debt obligations could place Diamond Offshore at a competitive disadvantage compared to its competitors that have less debt; • customers may react adversely to its significant debt level and seek alternative service providers; and • failure to comply with the restrictive covenants in its debt instruments that, among other things, require Diamond Offshore to maintain a specified ratio of its consolidated indebtedness to total capitalization and limit the ability of its subsidiaries to incur debt, could result in an event of default that, if not cured or waived, could have a material adverse effect on its business. In addition, Diamond Offshore’s $1.5 billion revolving credit facility matures on October 22, 2020, except for $40 million of commitments that mature on March 17, 2019 and $60 million of commitments that mature on October 22, 2019. Diamond Offshore’s ability to renew or replace its revolving credit facility is dependent on numerous factors, including its financial condition and prospects at the time and the then current state of the bank and capital markets in the U.S. Diamond Offshore’s liquidity may be adversely affected if it is unable to replace the revolving credit facility upon acceptable terms when it matures. In July of 2017, Moody’s downgraded Diamond Offshore’s corporate credit rating to Ba3 with a negative outlook from Ba2 with a stable outlook. In October of 2017, S&P downgraded Diamond Offshore’s corporate credit rating to B+ from BB- with a negative outlook. These credit ratings are below investment grade and could raise the cost of financing. As a consequence, Diamond Offshore may not be able to issue additional debt in amounts and/or with terms that it considers to be reasonable. Diamond Offshore’s revolving credit facility bears interest at variable rates, based on its corporate credit rating and market interest rates. If market interest rates increase, Diamond Offshore’s cost to borrow under its revolving credit facility may also increase. Although Diamond Offshore may employ hedging strategies such that a portion of the aggregate principal amount outstanding under this credit facility would effectively carry a fixed rate of interest, any hedging arrangement put in place may not offer complete protection from this risk. Risks Related to Us and Our Subsidiary, Boardwalk Pipeline Partners, LP Boardwalk Pipeline may not be able to replace expiring natural gas transportation contracts at attractive rates or on a long-term basis and may not be able to sell short-term services at attractive rates or at all due to market conditions. Each year, a portion of Boardwalk Pipeline’s firm natural gas transportation contracts expire and need to be replaced or renewed. Over the past several years, as a result of current market conditions, Boardwalk Pipeline has renewed some expiring contracts at lower rates or for shorter terms than in the past. In addition to normal contract expirations, in the 2018 to 2020 timeframe, transportation agreements associated with Boardwalk Pipeline’s Gulf South, Texas Gas and Gulf Crossing Pipeline expansion projects, which were placed into service in 2008 and 2009, will expire. These projects were large, new pipeline expansions that were developed to serve growing production in Texas, Oklahoma and Louisiana and anchored primarily by ten-year firm transportation agreements with producers and priced based on then current market conditions. As the terms of these remaining expansion contracts expire in 2018 through 2020, Boardwalk Pipeline will have significantly more transportation contract expirations than it has had during the past several years. If these contracts are renewed, Boardwalk Pipeline expects that the new contracts will be at lower rates and for shorter contract terms than the contracts they are replacing. If these contracts are renewed at current market rates, the revenues earned from these transportation contracts would be materially lower than they are today. For a discussion of current developments, see the Firm Transportation Agreements portion of the Results of Operations - Boardwalk Pipeline section of MD&A under Item 7. The narrowing of the price differentials between natural gas supplies and market demand for natural gas has reduced the transportation rates that Boardwalk Pipeline can charge. The transportation rates Boardwalk Pipeline is able to charge customers are heavily influenced by market trends (both short and longer term), including the available supply, geographical location of natural gas production, the competition between producing basins, competition with other pipelines for supply and markets, the demand for gas by end-users such as power plants, petrochemical facilities and LNG export facilities and the price differentials between the gas supplies and the market demand for the gas (basis differentials). Current market conditions have resulted in a sustained narrowing of basis differentials on certain portions of Boardwalk Pipeline’s pipeline system, which has reduced transportation rates that can be charged in the affected areas and adversely affected the contract terms Boardwalk Pipeline can secure from its customers for available transportation capacity and for contracts being renewed or replaced. The prevailing market conditions may also lead some of its customers to seek to renegotiate existing contracts to terms that are less attractive to Boardwalk Pipeline; for example, seeking a current price reduction in exchange for an extension of the contract term. Boardwalk Pipeline expects these market conditions to continue. Boardwalk Pipeline’s actual construction and development costs could exceed its forecasts, its anticipated cash flow from construction and development projects will not be immediate and its construction and development projects may not be completed on time or at all. Boardwalk Pipeline is engaged in multiple significant construction projects involving its existing assets and the construction of new facilities for which it has expended or will expend significant capital. Boardwalk Pipeline expects to continue to engage in the construction of additional growth projects and modifications of its system. When Boardwalk Pipeline builds a new pipeline or expands or modifies an existing facility, the design, construction and development occurs over an extended period of time, and it will not receive any revenue or cash flow from that project until after it is placed in service. Typically, there are several years between when the project is announced and when customers begin using the new facilities. During this period, Boardwalk Pipeline spends capital and incurs costs without receiving any of the financial benefits associated with the projects. The construction of new assets involves regulatory (federal, state and local), landowner opposition, environmental, activist, legal, political, materials and labor costs, as well as operational and other risks that are difficult to predict and beyond Boardwalk Pipeline’s control. Any of these projects may not be completed on time or at all due to a variety of factors, may be impacted by significant cost overruns or may be materially changed prior to completion as a result of developments or circumstances that Boardwalk Pipeline is not aware of when it commits to the project, including the inability of any shipper to provide adequate credit support or to otherwise perform their obligations under any precedent agreements. Any of these events could result in material unexpected costs or have a material adverse effect on Boardwalk Pipeline’s ability to realize the anticipated benefits from its growth projects. Boardwalk Pipeline’s natural gas transportation and storage operations are subject to extensive regulation by the FERC, including rules and regulations related to the rates it can charge for its services and its ability to construct or abandon facilities. Boardwalk Pipeline may not be able to recover the full cost of operating its pipelines, including earning a reasonable return. Boardwalk Pipeline’s natural gas transportation and storage operations are subject to extensive regulation by the FERC, including the types and terms of services Boardwalk Pipeline may offer to its customers, construction of new facilities, creation, modification or abandonment of services or facilities and recordkeeping and relationships with affiliated companies. An adverse FERC action in any of these areas could affect Boardwalk Pipeline’s ability to compete for business, construct new facilities, offer new services or recover the full cost of operating its pipelines. This regulatory oversight can result in longer lead times to develop and complete any future project than competitors that are not subject to the FERC’s regulations. The FERC can also deny Boardwalk Pipeline the right to abandon certain facilities from service. The FERC also regulates the rates Boardwalk Pipeline can charge for its natural gas transportation and storage operations. For cost-based services, the FERC establishes both the maximum and minimum rates Boardwalk Pipeline can charge. The basic elements that the FERC considers are the costs of providing service, the volumes of gas being transported, the rate design, the allocation of costs between services, the capital structure and the rate of return a pipeline is permitted to earn. The FERC has issued a notice of inquiry concerning the inclusion of income taxes in the rates of an interstate pipeline that operates as a master limited partnership. The ultimate outcome of this proceeding could impact the maximum rates Boardwalk Pipeline can charge on its FERC regulated pipelines. The FERC has not finalized this proceeding. Enacted on December 22, 2017, the Tax Act changed several provisions of the federal tax code, including a reduction in the maximum corporate tax rate. Since the Tax Act was signed into law, filings have been made at the FERC requesting that the FERC require pipelines to lower their transportation rates to account for lower corporate taxes. Following the effective date of the law, the FERC orders granting certificates to construct proposed pipeline facilities have directed pipelines proposing new rates for service on those facilities to re-file such rates so that the rates reflect the reduction in the corporate tax rate, and the FERC has issued data requests in pending certificate proceedings for proposed pipeline facilities requesting pipelines to explain the impacts of the reduction in the corporate tax rate on the rate proposals in those proceedings and to provide re-calculated initial rates for service on the proposed pipeline facilities. The FERC may enact other regulations or issue further requests to pipelines regarding the impact of the corporate tax rate change on the rates. The FERC’s establishment of a just and reasonable rate is based on many components, and the reduction in the corporate tax rate may only impact two such components, the allowance for income taxes and the amount for accumulated deferred income taxes. The FERC or Boardwalk Pipeline’s shippers may challenge rates in the future, which could result in a new rate that may be lower than the rates Boardwalk Pipeline currently charges. The FERC or Boardwalk Pipeline’s customers can challenge the existing rates on any of Boardwalk Pipeline’s pipelines. Such a challenge against Boardwalk Pipeline could adversely affect its ability to charge rates that would cover future increases in its costs or even to continue to collect rates to maintain its current revenue levels that are designed to permit a reasonable opportunity to recover current costs and depreciation and earn a reasonable return. In December of 2017, the FERC announced it will review its 1999 Policy Statement on Certification of New Interstate Natural Gas Pipeline Facilities that is used in the determination of whether to grant certificates for new pipeline projects. Boardwalk Pipeline is unable to predict what, if any, changes may be proposed that will affect its natural gas pipeline business or when such proposals, if any, might become effective. Boardwalk Pipeline does not expect that any change in this policy would affect it in a materially different manner than any other natural gas pipeline company operating in the U.S. Legislative and regulatory initiatives relating to pipeline safety that require the use of new or more prescriptive compliance activities, substantial changes to existing integrity management programs or withdrawal of regulatory waivers could subject Boardwalk Pipeline to increased capital and operating costs and operational delays. Boardwalk Pipeline’s interstate pipelines are subject to regulation by PHMSA, which is part of DOT. PHMSA regulates the design, installation, testing, construction, operation, replacement and management of existing interstate natural gas and NGLs pipeline facilities. PHMSA regulation currently requires pipeline operators to implement integrity management programs, including frequent inspections, correction of certain identified anomalies and other measures to promote pipeline safety in HCAs, such as high population areas, areas unusually sensitive to environmental damage and commercially navigable waterways. States have jurisdiction over certain of Boardwalk Pipeline’s intrastate pipelines and have adopted regulations similar to existing PHMSA regulations. State regulations may impose more stringent requirements than found under federal law that affect Boardwalk Pipeline’s intrastate operations. Compliance with these rules over time generally has resulted in an overall increase in maintenance costs. The imposition of new or more stringent pipeline safety rules applicable to natural gas or NGL pipelines, or any issuance or reinterpretation of guidance from PHMSA or any state agencies with respect thereto could cause Boardwalk Pipeline to install new or modified safety controls, pursue additional capital projects or conduct maintenance programs on an accelerated basis, any or all of which tasks could result in Boardwalk Pipeline incurring increased capital and operating costs, experience operational delays, and result in potential adverse impacts to its operations or ability to reliably serve its customers. Requirements that are imposed under the 2011 Act or the more recent 2016 Act may also increase Boardwalk Pipeline’s capital and operating costs or impact the operation of its pipelines. Boardwalk Pipeline has entered into certain firm transportation contracts with shippers on certain of its expansion projects that utilize the design capacity of certain of its pipeline assets, based upon the authority Boardwalk Pipeline received from PHMSA to operate those pipelines under special permits at higher than normal operating pressures of up to 0.80 of the pipeline’s SMYS. PHMSA retains discretion to withdraw or modify this authority. If PHMSA were to withdraw or materially modify such authority, it could affect Boardwalk Pipeline’s ability to transport all of its contracted quantities of natural gas on these pipeline assets and it could incur significant additional costs to reinstate this authority or to develop alternate ways to meet its contractual obligations. Boardwalk Pipeline is exposed to credit risk relating to default or bankruptcy by its customers. Credit risk relates to the risk of loss resulting from the default by a customer of its contractual obligations or the customer filing bankruptcy. Boardwalk Pipeline has credit risk with both its existing customers and those supporting its growth projects. Natural gas producers comprise a significant portion of Boardwalk Pipeline’s revenues and support several of its growth projects, including those recently placed into service. In 2017, approximately 46% of Boardwalk Pipeline’s revenues were generated from contracts with natural gas producers. For existing customers on its interstate pipelines, FERC gas tariffs limit the amount of credit support Boardwalk Pipeline can obtain. Over the past several years, the prices of oil and natural gas have been unstable. If oil and natural gas prices continue to remain unstable for a sustained period of time, Boardwalk Pipeline’s producer customers will be adversely affected, which could lead some customers to default on their obligations to Boardwalk Pipeline or file for bankruptcy. Credit risk also exists in relation to Boardwalk Pipeline’s growth projects, both because foundation customers make long term firm capacity commitments to Boardwalk Pipeline for such projects and certain of those foundation customers agree to provide credit support as construction for such projects progresses. If a customer fails to post the required credit support during the growth project process, overall returns on the project may be reduced to the extent an adjustment to the scope of the project results or Boardwalk Pipeline is unable to replace the defaulting customer. Boardwalk Pipeline’s credit exposure also includes receivables for services provided, future performance under firm agreements and volumes of gas owed by customers for imbalances or gas loaned by Boardwalk Pipeline to them under certain NNS and parking and lending (“PAL”) services. Boardwalk Pipeline relies on a limited number of customers for a significant portion of its revenues. For 2017, while no customer comprised 10% or more of its operating revenues, the top ten customers comprised approximately 41% of revenues. If any of Boardwalk Pipeline’s significant customers have credit or financial problems which result in bankruptcy, a delay or failure to pay for services provided by Boardwalk Pipeline to post the required credit support for construction associated with its growth projects or existing contracts or to repay the gas they owe Boardwalk Pipeline, it could have a material adverse effect on its business. Changes in energy prices, including natural gas, oil and NGLs, impact the supply of and demand for those commodities, which impact Boardwalk Pipeline’s business. Boardwalk Pipeline’s customers, especially producers, are directly impacted by changes in commodity prices. The prices of natural gas, oil and NGLs fluctuate in response to changes in supply and demand, market uncertainty and a variety of additional factors. The declines in the levels of natural gas, oil and NGLs prices experienced in recent history have adversely affected the businesses of Boardwalk Pipeline’s producer customers and reduced the demand for Boardwalk Pipeline’s services and could result in defaults or the non-renewal of Boardwalk Pipeline’s contracted capacity when existing contracts expire. Future increases in the price of natural gas and NGLs could make alternative energy and feedstock sources more competitive and reduce demand for natural gas and NGLs. A reduced level of demand for natural gas and NGLs could reduce the utilization of capacity on Boardwalk Pipeline’s systems and reduce the demand of its services. A significant portion of Boardwalk Pipeline’s debt will mature over the next five years and will need to be paid or refinanced and changes to the debt and equity markets could adversely affect its business. A significant portion of Boardwalk Pipeline’s debt is set to mature in the next five years, including its revolving credit facility. Boardwalk Pipeline may not be able to refinance its maturing debt on commercially reasonable terms, or at all, depending on numerous factors, including its financial condition and prospects at the time and the then current state of the banking and capital markets in the U.S. Limited access to the debt and equity markets could adversely affect Boardwalk Pipeline’s business. Boardwalk Pipeline’s current strategy is to fund its announced growth projects through currently available financing options, including utilizing cash generated from operations, borrowings under its revolving credit facility, accessing proceeds from its subordinated loan agreement with a subsidiary of the Company and accessing the capital markets. Changes in the debt and equity markets, including market disruptions, limited liquidity, and interest rate volatility, may increase the cost of financing as well as the risks of refinancing maturing debt. Instability in the financial markets may increase Boardwalk Pipeline’s cost of capital while reducing the availability of funds. This may affect its ability to raise capital and reduce the amount of cash available to fund its operations or growth projects. If the debt and equity markets were not available, it is not certain if other adequate financing options would be available to Boardwalk Pipeline on terms and conditions that it would find acceptable. Any disruption in the capital markets could require Boardwalk Pipeline to take additional measures to conserve cash until the markets stabilize or until it can arrange alternative credit arrangements or other funding for its business needs. Such measures could include reducing or delaying business activities, reducing its operations to lower expenses and reducing other discretionary uses of cash. Boardwalk Pipeline may be unable to execute its growth strategy or take advantage of certain business opportunities. Boardwalk Pipeline does not own all of the land on which its pipelines and facilities are located, which could result in disruptions to its operations. Boardwalk Pipeline does not own all of the land on which its pipelines and facilities have been constructed, and Boardwalk Pipeline is subject to the possibility of more onerous terms and/or increased costs to retain necessary land use if it does not have valid rights-of-way or if such rights-of-way lapse or terminate. Boardwalk Pipeline obtains the rights to construct and operate its pipelines on land owned by third parties and governmental agencies for a specific period of time. Boardwalk Pipeline cannot guarantee that it will always be able to renew, when necessary, existing rights-of-way or obtain new rights-of-way without experiencing significant costs. Any loss of these rights with respect to Boardwalk Pipeline’s real property, through its inability to renew right-of-way contracts or otherwise, could have a material adverse effect on its business. Boardwalk Pipeline may not be successful in executing its strategy to grow and diversify its business. Boardwalk Pipeline relies primarily on the revenues generated from its natural gas long-haul transportation and storage services. Negative developments in these services have significantly greater impact on Boardwalk Pipeline’s financial condition and results of operations than if it maintained more diverse assets. Boardwalk Pipeline is pursuing a strategy of growing and diversifying its business through acquisition and development of assets in complementary areas of the midstream energy sector, such as liquids transportation and storage assets. Boardwalk Pipeline’s ability to grow, diversify and increase distributable cash flows will depend, in part, on its ability to expand its existing business lines and to close and execute on accretive acquisitions. Boardwalk Pipeline may not be successful in acquiring or developing such assets or may do so on terms that ultimately are not profitable. Any such transactions involve potential risks that may include, among other things: • the diversion of management’s and employees’ attention from other business concerns; • inaccurate assumptions about volume, revenues and project costs, including potential synergies; • a decrease in Boardwalk Pipeline’s liquidity as a result of using available cash or borrowing capacity to finance the acquisition or project; • a significant increase in interest expense or financial leverage if it incurs additional debt to finance the acquisition or project; • inaccurate assumptions about the overall costs of equity or debt; • an inability to hire, train or retain qualified personnel to manage and operate the acquired business and assets or the developed assets; • unforeseen difficulties operating in new product areas or new geographic areas; and • changes in regulatory requirements or delays of regulatory approvals. Additionally, acquisitions also contain the following risks: • an inability to integrate successfully the businesses Boardwalk Pipeline acquires; • the assumption of unknown liabilities for which it is not indemnified, for which its indemnity is inadequate or for which its insurance policies may exclude from coverage; • limitations on rights to indemnity from the seller; and • customer or key employee losses of an acquired business. Boardwalk Pipeline’s ability to replace expiring gas storage contracts at attractive rates or on a long-term basis and to sell short-term services at attractive rates or at all are subject to market conditions. Boardwalk Pipeline owns and operates substantial natural gas storage facilities. The market for the storage and PAL services that it offers is impacted by the factors and market conditions discussed above for Boardwalk Pipeline’s transportation services, and is also impacted by natural gas price differentials between time periods, such as winter to summer (time period price spreads), and the volatility in time period price spreads. When market conditions cause a narrowing of time period price spreads and a decline in the price volatility of natural gas, these factors adversely impact the rates Boardwalk Pipeline can charge for its storage and PAL services. Boardwalk Pipeline’s operations are subject to catastrophic losses, operational hazards and unforeseen interruptions for which it may not be adequately insured. There are a variety of operating risks inherent in transporting and storing natural gas, ethylene and NGLs, such as leaks and other forms of releases, explosions, fires, cyber-attacks and mechanical problems, some of which could have catastrophic consequences. Additionally, the nature and location of Boardwalk Pipeline’s business may make it susceptible to catastrophic losses from hurricanes or other named storms, particularly with regard to its assets in the Gulf Coast region, windstorms, earthquakes, hail, and severe winter weather. Any of these or other similar occurrences could result in the disruption of Boardwalk Pipeline’s operations, substantial repair costs, personal injury or loss of human life, significant damage to property, environmental pollution, impairment of its operations and substantial financial losses. The location of pipelines in HCAs, which includes populated areas, residential areas, commercial business centers and industrial sites, could significantly increase the level of damages resulting from some of these risks. Boardwalk Pipeline currently possesses property, business interruption, cyber threat and general liability insurance, but proceeds from such insurance coverage may not be adequate for all liabilities or expenses incurred or revenues lost. Moreover, such insurance may not be available in the future at commercially reasonable costs and terms. The insurance coverage Boardwalk Pipeline does obtain may contain large deductibles or fail to cover certain events, hazards or all potential losses. Climate change legislation and regulations restricting emissions of greenhouse gases (“GHGs”) could result in increased operating and capital costs and reduced demand for Boardwalk Pipeline’s pipeline and storage services. Climate change continues to attract considerable public and scientific attention. As a result, numerous proposals have been made and are likely to continue to be made at the international, national, regional and state levels of government to monitor and limit emissions of greenhouse gases. While no comprehensive climate change legislation has been implemented at the federal level, the Environmental Protection Agency (“EPA”) and states or groupings of states have pursued legal initiatives in recent years that seek to reduce GHG emissions through efforts that include consideration of cap-and-trade programs, carbon taxes and GHG reporting and tracking programs and regulations that directly limit GHG emissions from certain sources such as, for example, limitations on emissions of methane through equipment control and leak detection and repair requirements. In particular, the EPA has adopted rules that, among other things, establish certain permit reviews for GHG emissions from certain large stationary sources, which reviews could require securing permits at covered facilities emitting GHGs and meeting defined technological standards for those GHG emissions. The EPA has also adopted rules requiring the monitoring and annual reporting of GHG emissions from certain petroleum and natural gas system sources in the U.S., including, among others, onshore processing, transmission, storage and distribution facilities as well as gathering, compression and boosting facilities and blowdowns of natural gas transmission pipelines. Federal agencies also have begun directly regulating emissions of methane, a GHG, from oil and natural gas operations. The adoption and implementation of any international, federal or state legislation or regulations that require reporting of GHGs or otherwise restrict emissions of GHGs could result in increased compliance costs or additional operating restrictions. Risks Related to Us and Our Subsidiary, Loews Hotels Holding Corporation Loews Hotels & Co’s business may be adversely affected by various operating risks common to the lodging industry, including competition, excess supply and dependence on business travel and tourism. Loews Hotels & Co owns and operates hotels which have different economic characteristics than many other real estate assets. A typical office property, for example, has long-term leases with third-party tenants, which provide a relatively stable long-term stream of revenue. Hotels, on the other hand, generate revenue from guests that typically stay at the hotel for only a few nights, which causes the room rate and occupancy levels at each hotel to change every day, and results in earnings that can be highly volatile. In addition, Loews Hotels & Co’s properties are subject to various operating risks common to the lodging industry, many of which are beyond Loews Hotels & Co’s control, including: • changes in general economic conditions, including the severity and duration of any downturn in the U.S. or global economy and financial markets; • war, political conditions or civil unrest, terrorist activities or threats and heightened travel security measures instituted in response to these events; • outbreaks of pandemic or contagious diseases; • natural or man-made disasters; • any material reduction or prolonged interruption of public utilities and services; • decreased corporate or government travel-related budgets and spending and cancellations, deferrals or renegotiations of group business due to adverse economic conditions or otherwise; • decreased need for business-related travel due to innovations in business-related technology; • competition from other hotels and alternative accommodations, such as Airbnb, in the markets in which Loews Hotels & Co operates; • requirements for periodic capital reinvestment to maintain and upgrade hotels; • increases in operating costs, including labor (including minimum wage increases), workers’ compensation, benefits, insurance, food, energy and unanticipated costs resulting from force majeure events, due to inflation, new or different federal, state or local governmental regulations and other factors that may not be offset by increased room rates; • the costs and administrative burdens associated with compliance with applicable laws and regulations; • organized labor activities, which could cause a diversion of business from hotels involved in labor negotiations and loss of business for Loews Hotels & Co’s properties generally as a result of certain labor tactics; • changes in the desirability of particular locations or travel patterns of customers, including with respect to the underlying attractions supporting Loews Hotels & Co’s existing and under development immersive destination properties, such as the Universal theme park for its Orlando, Florida properties, the stadiums in Arlington, Texas and St. Louis, Missouri for its Live! By Loews hotels and the convention center for its Kansas City Hotel, geographic concentration of its operations and customers and shortages of desirable locations for development; and • relationships with third-party property owners, developers, landlords and joint venture partners, including the risk that owners and/or partners may terminate management or joint venture agreements. These factors, and the reputational repercussions of these factors, could adversely affect, and from time to time have adversely affected, individual hotels and hotels in particular regions. Loews Hotels & Co is exposed to the risks resulting from significant investments in owned and leased real estate, which could increase its costs, reduce its profits, limit its ability to respond to market conditions or restrict its growth strategy. Loews Hotels & Co’s proportion of owned and leased properties, compared to the number of properties that it manages for third-party owners, is larger than that of some of its competitors. Real estate ownership and leasing is subject to risks not applicable to managed or franchised properties, including: • real estate, insurance, zoning, tax, environmental and eminent domain laws; • the ongoing need for owner-funded capital improvements and expenditures to maintain or upgrade properties; • risks associated with mortgage debt, including the possibility of default, fluctuating interest rate levels and the availability of replacement financing; • risks associated with the possibility that cost increases will outpace revenue increases and that, in the event of an economic slowdown, a high proportion of fixed costs will make it difficult to reduce costs to the extent required to offset declining revenues; • risks associated with real estate leases, including the possibility of rent increases and the inability to renew or extend upon favorable terms; • fluctuations in real estate values and potential impairments in the value of Loews Hotels & Co’s assets; and • the relative illiquidity of real estate compared to some other assets. The hospitality industry is subject to seasonal and cyclical volatility. The hospitality industry is seasonal in nature. The periods during which Loews Hotels & Co’s properties experience higher revenues vary from property to property, depending principally upon location and the consumer base served. Loews Hotels & Co generally expects revenues to be lower in the first quarter of each year than in each of the three subsequent quarters. In addition, the hospitality industry is cyclical and demand generally follows the general economy on a lagged basis. The seasonality and cyclicality of its industry may contribute to fluctuation in Loews Hotels & Co’s results of operations and financial condition. Loews Hotels & Co operates in a highly competitive industry, both for customers and for acquisitions and developments of new properties. The lodging industry is highly competitive. Loews Hotels & Co’s properties compete with other hotels and alternative accommodations based on a number of factors, including room rates, quality of accommodations, service levels and amenities, location, brand affiliation, reputation and reservation systems. New hotels may be constructed and these additions to supply create new competitors, in some cases without corresponding increases in demand for hotel rooms. Some of its competitors also have greater financial and marketing resources than Loews Hotels & Co. In addition, travelers can book stays on websites that facilitate the short-term rental of homes and apartments from owners, thereby providing an alternative to hotel rooms. Loews Hotels & Co also competes for hotel acquisitions and development projects with entities that have similar investment objectives as it does. This competition could limit the number of suitable investment opportunities. It may also increase the bargaining power of Loews Hotels & Co’s counterparties, making it more difficult for Loews Hotels & Co to acquire or develop new properties on attractive terms or on the terms contemplated in its business plan. Any deterioration in the quality or reputation of Loews Hotels & Co’s brands could have an adverse effect on its reputation and business. Loews Hotels & Co’s brands and its reputation are among its most important assets. Its ability to attract and retain guests depends, in part, on the public recognition of its brands and their associated reputation. If its brands become obsolete or consumers view them as unfashionable or lacking in consistency and quality, or its brands or reputation are otherwise harmed, Loews Hotels & Co may be unable to attract guests to its properties, and may further be unable to attract or retain joint venture partners or hotel owners. Loews Hotels & Co’s efforts to develop new properties and renovate existing properties could be delayed or become more expensive. Loews Hotels & Co from time to time renovates its properties and is currently expanding its portfolio through the ground-up construction of a number of new developments, including new properties in Orlando, Florida, Arlington, Texas, Kansas City, Missouri and St. Louis, Missouri and in the future may similarly develop additional new properties. Often these projects are undertaken with joint venture partners. These efforts are subject to a number of risks, including: • construction delays or cost overruns (including labor and materials or unforeseeable site conditions) that may increase project costs or cause new development projects to not be completed by lender imposed required completion dates; • obtaining zoning, occupancy and other required permits or authorizations; • changes in economic conditions that may result in weakened or lack of demand or negative project returns; • governmental restrictions on the size or kind of development; • force majeure events, including earthquakes, tornados, hurricanes or floods; and • design defects that could increase costs. Additionally, developing new properties typically involves lengthy development periods during which significant amounts of capital must be funded before the properties begin to operate and generate revenue. If the cost of funding new development exceeds budgeted amounts, and/or the time period for development is longer than initially anticipated, Loews Hotels & Co’s profits could be reduced. Further, due to the lengthy development cycle, intervening adverse economic conditions in general and as they apply to Loews Hotels & Co and its development partners may alter or impede the development plans, thereby resulting in incremental costs or potential impairment charges. In addition, using multiple sources of capital to develop new properties reduces or eliminates the ability of Loews Hotels & Co to cease commenced projects if the overall economic environment conditions change. Moreover, during the early stages of operations, charges related to interest expense and depreciation may substantially detract from, or even outweigh, the profitability of certain new property investments. Loews Hotels & Co’s properties are geographically concentrated, which exposes its business to the effects of regional events and occurrences. Loews Hotels & Co has a concentration of hotels in Florida. Specifically, as of December 31, 2017, six hotels, representing approximately 49% of rooms in its system, were located in Florida. The concentration of hotels in one region or a limited number of markets may expose Loews Hotels & Co to risks of adverse economic and other developments that are greater than if its portfolio were more geographically diverse. These developments include regional economic downturns, a decline in the popularity of or access to area tourist attractions, such as theme parks, significant increases in the number of Loews Hotels & Co’s competitors’ hotels in these markets and potentially higher local property, sales and income taxes in the geographic markets in which it is concentrated. In addition, Loews Hotels & Co’s properties in Florida are subject to the effects of adverse acts of nature, such as hurricanes, strong winds and flooding, which have in the past caused damage to its hotels in Florida, which may in the future be intensified as a result of climate change, as well as outbreaks of pandemic or contagious diseases. The growth and use of alternative reservation channels adversely affects Loews Hotels & Co’s business. A significant percentage of hotel rooms for guests at Loews Hotels & Co’s properties is booked through internet travel and other intermediaries. In most cases, Loews Hotels & Co has agreements with such intermediaries and pays them commissions and/or fees for sales of its rooms through their systems. If such bookings increase, these intermediaries may be able to obtain higher commissions or fees, reduced room rates or other significant concessions from Loews Hotels & Co. There can be no assurance that Loews Hotels & Co will be able to negotiate such agreements in the future with terms as favorable as those that exist today. Moreover, these intermediaries generally employ aggressive marketing strategies, including expending significant resources for online and television advertising campaigns to drive consumers to their websites and other outlets. As a result, consumers may develop brand loyalties to the intermediaries’ offered brands, websites and reservations systems rather than to Loews Hotels & Co’s brands. Under certain circumstances, Loews Hotels & Co’s insurance coverage may not cover all possible losses, and it may not be able to renew its insurance policies on favorable terms, or at all. Although Loews Hotels & Co maintains various property, casualty and other insurance policies, proceeds from such insurance coverage may not be adequate for all liabilities or expenses incurred or revenues lost. Moreover, such insurance may not be available in the future at commercially reasonable costs and terms. The insurance coverage Loews Hotels & Co does obtain may contain large deductibles or fail to cover certain events, hazards or all potential losses. Labor shortages could restrict Loews Hotels & Co’s ability to operate its properties or grow its business or result in increased labor costs that could reduce its profits. Loews Hotels & Co’s properties are staffed 24 hours a day, seven days a week by thousands of employees. If it is unable to attract, retain, train and engage skilled employees, its ability to manage and staff its properties adequately could be impaired, which could reduce customer satisfaction. Staffing shortages could also hinder its ability to grow and expand its business. Because payroll costs are a major component of the operating expenses at its properties, a shortage of skilled labor could also require higher wages that would increase its labor costs. Risks Related to Us and Our Subsidiary, Consolidated Container Company LLC Consolidated Container’s substantial indebtedness could affect its ability to meet its obligations and may otherwise restrict its activities. Consolidated Container has a significant amount of indebtedness, which requires significant interest payments. Its inability to generate sufficient cash flow to satisfy its debt obligations, or to refinance its obligations on commercially reasonable terms, would have a material adverse effect on its business. Consolidated Container’s substantial indebtedness could have important consequences. For example, it could: • limit its ability to borrow money for its working capital, capital expenditures, debt service requirements or other corporate purposes; • increase its vulnerability to general adverse economic and industry conditions; and • limit its ability to respond to business opportunities, including growing its business through acquisitions. In addition, the credit agreements governing its current indebtedness contain, and any future debt instruments would likely contain, financial and other restrictive covenants, which impose significant operating and financial restrictions on it. As a result of these covenants, Consolidated Container could be limited in the manner in which it conducts its business and may be unable to engage in favorable business activities or finance future operations or capital needs. Furthermore, a failure to comply with these covenants could result in an event of default which, if not cured or waived, could have a material adverse effect on Consolidated Container. Fluctuations in raw material prices and raw material availability may affect Consolidated Container’s results. To produce its products, Consolidated Container uses large quantities of plastic resins and recycled plastic materials. It faces the risk that its access to these raw materials may be interrupted or that it may not be able to purchase these raw materials at prices that are acceptable to it. In general, Consolidated Container does not have long-term supply contracts with its suppliers, and its purchases of raw materials are subject to market price volatility. Although Consolidated Container generally is able to pass changes in the prices of raw materials through to its customers over a period of time, it may not always be able to do so or there may be a lag between when its costs increase and when it passes those costs through to its customers. It may not be able to pass through all future raw material price increases in a timely manner or at all due to competitive pressures. In addition, a sustained increase in resin and recycled plastic prices, relative to alternative packaging materials, would make plastic containers less economical for its customers and could result in a slower pace of conversions to, or reductions in the use of, plastic containers. Any limitation on its ability to procure its primary raw materials or to pass through price increases in such materials on a timely basis could negatively affect Consolidated Container. Consolidated Container’s customers may increase their self-manufacturing. Increased self-manufacturing by Consolidated Container’s customers may have a material adverse impact on its sales volume and financial results. Consolidated Container believes that its customers may engage in self-manufacturing over time at locations where transportation costs are high, and where low complexity and available space to install blow molding equipment exists. Risks Related to Us and Our Subsidiaries Generally In addition to the specific risks and uncertainties faced by our subsidiaries, as discussed above, we and all of our subsidiaries face additional risks and uncertainties described below. Acts of terrorism could harm us and our subsidiaries. Terrorist attacks and the continued threat of terrorism in the United States or abroad, the continuation or escalation of existing armed hostilities or the outbreak of additional hostilities, including military and other action by the United States and its allies, could have a significant impact on us and the assets and businesses of our subsidiaries. CNA issues coverages that are exposed to risk of loss from an act of terrorism. Terrorist acts or the threat of terrorism could also result in increased political, economic and financial market instability, a decline in energy consumption and volatility in the price of oil and gas, which could affect the market for Diamond Offshore’s drilling services and Boardwalk Pipeline’s transportation and storage services. In addition, future terrorist attacks could lead to reductions in business travel and tourism which could harm Loews Hotels. While our subsidiaries take steps that they believe are appropriate to secure their assets, there is no assurance that they can completely secure them against a terrorist attack or obtain adequate insurance coverage for terrorist acts at reasonable rates. Changes in tax laws, regulations or treaties, or the interpretation or enforcement thereof in jurisdictions in which we or our subsidiaries operate could adversely impact us. Changes in federal, state or foreign tax laws, regulations or treaties applicable to us or our subsidiaries or changes in the interpretation or enforcement thereof could materially and adversely impact our and our subsidiaries’ tax liability, financial condition, results of operations and cash flows, including the amount of cash our subsidiaries have available to distribute to their shareholders, including us. In particular, potential changes to tax laws relating to tax credits, the corporate tax rate or the taxation of interest from municipal bonds (and thus the rate at which CNA discounts its long term care reserves), foreign earnings and publicly traded partnerships could have such material adverse effects. Our subsidiaries face significant risks related to compliance with environmental laws. Our subsidiaries have extensive obligations and financial exposure related to compliance with federal, state, local, foreign and international environmental laws, including those relating to the discharge of substances into the environment, the disposal, removal or clean up of hazardous wastes and other activities relating to the protection of the environment. Many of such laws have become increasingly stringent in recent years and may in some cases impose strict liability, which could be substantial, rendering a person liable for environmental damage without regard to negligence or fault on the part of that person. For example, Diamond Offshore could be liable for damages and costs incurred in connection with oil spills related to its operations, including for conduct of or conditions caused by others. Boardwalk Pipeline is also subject to environmental laws and regulations, including requiring the acquisition of permits or other approvals to conduct regulated activities, restricting the manner in which it disposes of waste, requiring remedial action to remove or mitigate contamination resulting from a spill or other release and requiring capital expenditures to comply with pollution control requirements. Further, existing environmental laws or the interpretation or enforcement thereof may be amended and new laws may be adopted in the future. Failures or interruptions in or breaches to our or our subsidiaries’ computer systems could materially and adversely affect our or our subsidiaries’ operations. We and our subsidiaries are dependent upon information technologies, computer systems and networks, including those maintained by us and our subsidiaries and those maintained and provided to us and our subsidiaries by third parties (for example, “software-as-a-service” and cloud solutions), to conduct operations and are reliant on technology to help increase efficiency in our and their businesses. We and our subsidiaries are dependent upon operational and financial computer systems to process the data necessary to conduct almost all aspects of our and their businesses. Any failure of our or our subsidiaries’ computer systems, or those of our or their customers, vendors or others with whom we and they do business, could materially disrupt business operations. Computer, telecommunications and other business facilities and systems could become unavailable or impaired from a variety of causes, including storms and other natural disasters, terrorist attacks, fires, utility outages, theft, design defects, human error or complications encountered as existing systems are replaced or upgraded. In addition, it has been reported that unknown entities or groups have mounted so-called “cyber attacks” on businesses and other organizations solely to disable or disrupt computer systems, disrupt operations and, in some cases, steal data. In particular, the U.S. government has issued public warnings that indicate energy assets may be specific targets of cyber attacks, which can have catastrophic consequences and there have also been reports that hotel chains, among other consumer-facing businesses, have been subject to various cyber attacks targeting payment card and other sensitive consumer information. Breaches of our and our subsidiaries’ computer security infrastructure can result from actions by our employees, vendors, third party administrators or by unknown third parties, and may disrupt our or their operations, cause damage to our or their assets and surrounding areas and impact our or their data framework or cause a failure to protect personal information of customers or employees. The foregoing risks relating to disruption of service, interruption of operations and data loss could impact our and our subsidiaries’ ability to timely perform critical business functions, resulting in disruption or deterioration in our and our subsidiaries’ operations and business and expose us and our subsidiaries to monetary and reputational damages. In addition, potential exposures include substantially increased compliance costs and required computer system upgrades and security related investments. The breach of confidential information also could give rise to legal liability and regulatory action under data protection and privacy laws and regulations, both in the U.S. and foreign jurisdictions. Some of our subsidiaries’ customer bases are concentrated. Some of our subsidiaries’ customer bases are concentrated. For instance, during 2017, two of Diamond Offshore’s customers in the Gulf of Mexico and Diamond Offshore’s three largest customers accounted for 41% and an aggregate of 60% of its annual total consolidated revenues. In addition, the number of customers that it has performed services for declined from 35 in 2014 to 14 in 2017. For Boardwalk Pipeline, while no customer comprised more than 10% or more of its operating revenues, its top ten customers comprised approximately 41% of its revenues during 2017. Consolidated Container also depends on several large customers. The loss of or other problem with a significant customer could have a material adverse impact on these subsidiaries’ and our financial results. Loss of key vendor relationships or issues relating to the transitioning of vendor relationships could result in a materially adverse effect on our and our subsidiaries’ operations. We and our subsidiaries rely on products, equipment and services provided by many third party suppliers, manufacturers and service providers in the United States and abroad, which exposes us and them to volatility in the quality, price and availability of such items. These include, for example, vendors of computer hardware, software and services, as well as other critical materials and services (including, in the case of CNA, claims administrators performing significant claims administration and adjudication functions). Certain products, equipment and services may be available from a limited number of sources. If one or more key vendors becomes unable to continue to provide products, equipment or services at the requisite level for any reason, or fails to protect our proprietary information, including in some cases personal information of employees, customers or hotel guests, we and our subsidiaries may experience a material adverse effect on our or their business, operations and reputation. We could incur impairment charges related to the carrying value of the long-lived assets and goodwill of our subsidiaries. Our subsidiaries regularly evaluate their long-lived assets and goodwill for impairment whenever events or changes in circumstances indicate the carrying value of these assets may not be recoverable. Most notably, we could incur impairment charges related to the carrying value of offshore drilling equipment at Diamond Offshore, pipeline and storage assets at Boardwalk Pipeline and hotel properties owned by Loews Hotels. In particular, Diamond Offshore is currently experiencing declining demand for certain offshore drilling rigs as a result of excess rig supply in the industry and depressed market conditions. As a result, Diamond Offshore may incur additional asset impairments, rig retirements and/or rigs being scrapped. We also test goodwill for impairment on an annual basis or when events or changes in circumstances indicate that a potential impairment exists. Asset impairment evaluations by us and our subsidiaries with respect to both long-lived assets and goodwill are, by nature, highly subjective. The use of different estimates and assumptions could result in materially different carrying values of our assets which could impact the need to record an impairment charge and the amount of any charge taken. We are a holding company and derive substantially all of our income and cash flow from our subsidiaries. We rely upon our invested cash balances and distributions from our subsidiaries to generate the funds necessary to meet our obligations and to declare and pay any dividends to holders of our common stock. Our subsidiaries are separate and independent legal entities and have no obligation, contingent or otherwise, to make funds available to us, whether in the form of loans, dividends or otherwise. The ability of our subsidiaries to pay dividends is subject to, among other things, the availability of sufficient earnings and funds in such subsidiaries, applicable state laws, including in the case of the insurance subsidiaries of CNA, laws and rules governing the payment of dividends by regulated insurance companies, and their compliance with covenants in their respective loan agreements. Claims of creditors of our subsidiaries will generally have priority as to the assets of such subsidiaries over our claims and those of our creditors and shareholders. We and our subsidiaries face competition for senior executives and qualified specialized talent. We and our subsidiaries depend on the services of our key personnel, who possess skills critical to the operation of our and their businesses. Our and our subsidiaries’ executive management teams are highly experienced and possess extensive skills in their relevant industries. The ability to retain senior executives and to attract and retain highly skilled professionals and personnel with specialized industry and technical experience is important to our and our subsidiaries’ success and future growth. Competition for this talent can be intense, and we and our subsidiaries may not be successful in our efforts. The unexpected loss of the services of these individuals could have a detrimental effect on us and our subsidiaries and could hinder our and their ability to effectively compete in the various industries in which we and they operate. From time to time we and our subsidiaries are subject to litigation, for which we and they may be unable to accurately assess the level of exposure and which if adversely determined, may have a significant adverse effect on our or their consolidated financial condition or results of operations. We and our subsidiaries are or may become parties to legal proceedings and disputes. These matters may include, among others, contract disputes, claims disputes, reinsurance disputes, personal injury claims, environmental claims or proceedings, asbestos and other toxic tort claims, intellectual property disputes, disputes related to employment and tax matters and other litigation incidental to our or their businesses. Although our current assessment is that, other than as disclosed in this Report, there is no pending litigation that could have a significant adverse impact, it is difficult to predict the outcome or effect of any litigation matters and if our assessment proves to be in error, then the outcome of litigation could have a significant impact on our financial statements. We could have liability in the future for tobacco-related lawsuits. As a result of our ownership of Lorillard, Inc. (“Lorillard”) prior to the separation of Lorillard from us in 2008 (the “Separation”), from time to time we have been named as a defendant in tobacco-related lawsuits and could be named as a defendant in additional tobacco-related suits, notwithstanding the completion of the Separation. In the Separation Agreement entered into between us and Lorillard and its subsidiaries in connection with the Separation, Lorillard and each of its subsidiaries has agreed to indemnify us for liabilities related to Lorillard’s tobacco business, including liabilities that we may incur for current and future tobacco-related litigation against us. While we do not believe that we have any liability for tobacco-related claims, and we have never been held liable for any such claims, an adverse decision in a tobacco-related lawsuit against us could, if the indemnification is deemed for any reason to be unenforceable or any amounts owed to us thereunder are not collectible, in whole or in part, have a material adverse effect on us.
