Declines in oil and natural gas prices or decreases in demand for oil and natural gas for an extended period of time, or market expectations of potential decreases in these prices and demand, could negatively affect our future growth in the tanker and offshore sector. Sustained periods of low oil and natural gas prices typically result in reduced exploration and extraction because oil and natural gas companies'companies’ capital expenditure budgets are subject to cash flow from such activities and are therefore sensitive to changes in energy prices. These changes in commodity prices can have a material effect on demand for our services, and periods of low demand can cause excess vessel supply and intensify the competition in the industry, which often results in vessels, particularly older and less technologically-advanced vessels, being idle for long periods of time. We cannot predict the future level of demand for our services or future conditions of the oil and natural gas industry. Any decrease in exploration, development or production expenditures by oil and natural gas companies or decrease in the demand for oil and natural gas could reduce our revenues and materially harm our business, results of operations and cash available for distribution.

Any decrease in shipments of crude oil from the above-mentioned geographical areas could have a material adverse effect on our financial performance. Among the factors which could lead to such a decrease are:

In addition, conditions affecting the world economy and the economics of the United States , China and the world economies such as ChinaIndia may result in reduced consumption of oil products and a decreased demand for our vessels and lower charter rates, which could have a material adverse effect on our earnings and our ability to pay dividends.

The market supply of tankers is affected by a number of factors, such as supply and demand for energy resources, including oil and petroleum products, supply and demand for seaborne transportation of such energy resources, and the current and expected purchase orders for newbuildings.newbuildings and the number of vessels being recycled. If the capacity of new tankers delivered exceeds the capacity of tankers being scrapped andrecycled or converted to non-trading tankers, tanker capacity will increase. If the supply of tanker capacity increases and if the demand for tanker capacity decreases or does not increase correspondingly, charter rates could materially decline. A reduction in charter rates and the value of our vessels may have a material adverse effect on our results of operations and earnings and available cash and our ability to comply with the covenants in our loan agreements.

The offshore production, storage and export industry is cyclical and volatile. Our growth strategy is partially based on expansion in the offshore FSO sector, which depends on the level of activity in oil and natural gas exploration, development and production in offshore areas worldwide. The availability of quality FSO prospects, exploration success, relative production costs, the stage of reservoir development and political and regulatory environments affect customers'customers’ FSO programs. Oil and natural gas prices and market expectations of potential changes in these prices or decreases in the demand for oil and gas also significantly affect this level of activity and demand for offshore units.units as does the difference in cost between a floating vessel compared to a fixed installation connected through pipelines.

We operate our vessels in markets that have historically exhibited seasonal variations in demand and, as a result, charter rates. Peaks in tanker demand quite often precede seasonal oil consumption peaks, as refiners and suppliers anticipate consumer demand. Seasonal peaks in oil demand can broadly be classified into two main categories: (1) increased demand prior to Northern Hemisphere winters as heating oil consumption increases and (2) increased demand for gasoline prior to the summer driving season in the United States. Unpredictable weather patterns and variations in oil reserves disrupt tanker scheduling. This seasonality may result in quarter-to-quarter volatility in our operating results, as many of our vessels trade in the spot market. Seasonal variations in tanker demand will affect any spot market related rates that we may receive.

We conduct most of our operations outside of the United States, and our business, results of operations, cash flows, financial condition and ability to pay dividends, if any, in the future may be adversely affected by changing economic, political and government conditions in the countries and regions where our vessels are employed or registered. Moreover, we operate in a sector of the economy that is likely to be adversely impacted by the effects of political conflicts.

Continuing conflicts and recent developments in the Middle East, including increased tensions between the United States and Iran which in January 2020 escalated into a the United States airstrike in Baghdad that killed a high-ranking Iranian general, as well as the presence of the United States or other armed forces in Iraq, Syria, Afghanistan and various other regions, may lead to additional acts of terrorism and armed conflict around the world, which may contribute to further economic instability in the global financial markets and current economic conditions mayinternational commerce. Additionally, any escalations between the United States and Iran could result in retaliation from Iran that could potentially affect the shipping industry, through increased attacks on vessels in the Strait of Hormuz (which already experienced an increased number of attacks on and seizures of vessels in 2019). These uncertainties could also adversely impactaffect our ability to obtain additional financing or insurance on terms acceptable to us or at all. Any of these occurrences could have a material adverse impact on our operating results, revenues and costs.

We anticipate a significant number of the port calls made by our vessels will continue to involve loading or discharging operations in ports in the Asia Pacific region. As a result, any negative changes in economic conditions in any Asia Pacific country, particularly in China, may have a material adverse effect on our business, financial condition and results of operations, as well as our future prospects. Before the global economic financial crisis that began in 2008, China had one of the world's fastest growing economies in terms of gross domestic product, or GDP, which had a significant impact on shipping demand. The year-over-year growth rate of China's GDP was approximately 6.1% for the year ended December 31, 2019, as compared to approximately 6.6% for the year ended December 31, 2018, and continues to remain below pre-2008 levels. We cannot assure you that the Chinese economy will not experience a significant contraction in the future. Furthermore, there is a rising threat of a Chinese financial crisis resulting from massive personal and corporate indebtedness and “trade wars”. In late 2019, the International Monetary Fund warned that continuing trade tensions, including significant tariff increases, between the United States and China are expected to result in a 0.8% cumulative reduction of global GDP in 2020. Additionally, following the emergence of COVID-19, industrial activity in China came to a quick halt in early 2020 with the rest of the world following soon thereafter. The outbreak of COVID-19 is a very negative development for the global economy and has led to a worldwide economic contraction. We cannot assure you that the global economy will not continue to contract in the future or that global GDP will not be be affected beyond the IMF’s initial forecast.

The recent outbreak of COVID-19, a novel coronavirus causing potentially deadly respiratory tract infections originating in China and subsequently spreading around the world, has negatively affected economic conditions, the supply chain, the labor market, the demand for shipping regionally as well as globally and may otherwise impact our operations and the operations of our customers and suppliers. As of March 2020, the outbreak of COVID-19 has been declared a pandemic by the World Health Organization (“WHO”). Governments in affected countries are imposing travel bans, quarantines and other emergency public health measures. As of March 15, 2020, the United States has temporarily restricted travel by foreign nationals into the country from a number of areas, including China and Europe. In addition, on March 18, 2020, the U.S. and Canada agreed to restrict all nonessential travel across the border. Companies are also taking precautions, such as requiring employees to work remotely, imposing travel restrictions and temporarily closing businesses. These restrictions, and future prevention and mitigation measures, are likely to have an adverse impact on global economic conditions, which could materially and adversely affect our future operations. Uncertainties regarding the economic impact of the COVID-19 outbreak are likely to result in sustained market turmoil, which could also negatively impact our business.

The economies of the United States, the E.U. and other parts of the world continue to experience relatively slow growth and exhibit weak economic trends. The creditCredit markets in the United States and Europe have in the past experienced significant contraction, de-leveraging and reduced liquidity, and there is a risk that the U.S.United States federal government and state governments and European authorities continue to implement a broad variety of governmental action and/or new regulation of the financial markets. Global financial markets and economic conditions have been, and continue to be, severely disrupted and volatile. Since 2008, lending by financial institutions worldwide remains at significantly lower levels than in the period preceding 2008.

We face risks attendant to changes in economic environments, changes in interest rates, and instability in the banking and securities markets around the world, among other factors. Major market disruptions may adversely affect our business or impair our ability to borrow amounts under our credit facilities or any future financial arrangements. In the absence of available financing, we also may be unable to take advantage of business opportunities or respond to competitive pressures.

In addition, as a result of the economic turmoil in Greece resulting from the sovereign debt crisis and the related austerity measures implemented by the Greek government, our operations in Greece may continue to be subjected to new regulations that may require us to incur new or additional compliance or other administrative costs and may require that we pay to the Greek government new taxes or other fees. We cannot predict how longalso face the current market conditions will last. However, these recentrisk that strikes, work stoppages, civil unrest and developing economic and governmental factors, together with the concurrent decline in charter rates and vessel values,violence within Greece may have a material adverse effect ondisrupt our results ofshoreside operations and financial condition and may cause the pricethose of our ordinary shares to decline.managers located in Greece.

As a result of the credit crisis in Europe, in particular in Greece, Italy, Ireland, Portugal and Spain, the European Commission created the European Financial Stability Facility, or the EFSF, and the European Financial Stability Mechanism, or the EFSM, to provide funding to Eurozone countries in financial difficulties that seek such support. In March 2011, the European Council agreed on the need for Eurozone countries to establish a permanent stability mechanism, the European Stability Mechanism, or the ESM, which was established on September 27, 2012activated by mutual agreement, to assume the role of the EFSF and the EFSM in providing external financial assistance to Eurozone countries.countries entered into force in May 2013. Despite these measures, and certainly against the background of the recent COVID-19 outbreak, concerns persist regarding the debt burden of certain Eurozone countries and their ability to meet future financial obligations and the overall stability of the Euro. An extended period of adverse development in the outlook for European countries could still reduce the overall demand for oil and gas andthus for our services. These potential developments, or market perceptions concerning these and related issues, could affect our financial position, results of operations and cash flow.

We rely on third-parties to provide supplies and services necessary for our operations, including equipment suppliers, caterers and machinery suppliers. Recent mergers have reduced the number of available suppliers, resulting in fewer alternatives for sourcing key supplies. With respect to certain items, we are generally dependent upon the original equipment manufacturer for repair and replacement of the item or its spare parts. Such consolidation may result in a shortage of supplies and services thereby increasing the cost of supplies and/or potentially inhibiting the ability of suppliers to deliver on time. These cost increases or delays could have a material adverse effect on our results of operations and result in downtime, and delays in the repair and maintenance of our vessels and FSOs. Furthermore, many of our suppliers are U.S. companies or non-U.S. subsidiaries owned or controlled by U.S. companies, which means that in the event a U.S. supplier was debarred or otherwise restricted by the U.S. government from delivering products, our ability to supply and service our operations could be materially impacted. In addition, through regulation and permitting, certain foreign governments effectively restrict the number of suppliers and technicians available to supply and service our operations in those jurisdictions, which could materially impact our operations and financial condition.

We operate worldwide, where appropriate, through agents or other intermediaries. Compliance with complex local, foreign and U.S. laws and regulations that apply to our international operations increases our cost of doing business. These numerous and sometimes conflicting laws and regulations include, among others, data privacy requirements (particularly with respect to(in particular the recent invalidation ofEuropean General Data Protection Regulation, enforceable as from May 25, 2018 and the United States-European Union safe harborEU-US Privacy Shield Framework, as adopted by the European Court of Justice)Commission on July 12, 2016), labor relations laws, tax laws, anti-competition regulations, import and trade restrictions, export requirements, U.S. laws such as the FCPA and other U.S. federal laws and regulations established by the office of Foreign Asset Control, local laws such as the UK Bribery Act 2010 or other local laws which prohibit corrupt payments to governmental officials or certain payments or remunerations to customers.

Given the high level of complexity of these laws, there is a risk that we may inadvertently breach some provisions. Violations of these laws and regulations could result in fines, criminal sanctions against us, our officers or our employees, requirements to obtain export licenses, cessation of business activities in sanctioned countries, implementation of compliance programs, and prohibitions on the conduct of our business. Violations of laws and regulations also could result in prohibitions on our ability to operate in one or more countries and could materially damage our reputation, our ability to attract and retain employees, or our business, results of operations and financial condition. Furthermore, detecting, investigating and resolving actual or alleged violations is expensive and can consume significant time and attention of our senior management.

Our operations are subject to numerous laws and regulations in the form of international conventions and treaties, national, state and local laws and national and international regulations in force in the jurisdictions in which our vessels operate or are registered, which can significantly affect the ownership and operation of our vessels. These requirements include, but are not limited to, the United States, or U.S., Oil Pollution Act of 1990, or OPA, the U.S. Comprehensive Environmental Response, Compensation and Liability Act of 1980, or CERCLA, the U.S. Clean Air Act, or the CAA, the U.S. Clean Water Act, or the CWA, the U.S. Marine Transportation Security Act of 2002, or the MTSA, European Union or E.U., regulations, regulations of the United Nations International Maritime Organization, or the IMO, including the International Convention for the Prevention of Pollution from Ships of 1973, as from time to time amended and generally referred to as MARPOL, including the designation of Emission Control Areas, or ECAs, thereunder, the International Convention on Load Lines of 1966, and the International Ship and Port Facility Security Code, or the ISPS Code. Compliance with such laws and regulations, where applicable, may require installation of costly equipment or operational changes and may affect the resale value or useful lives of our vessels. We may also incur additional costs in order to comply with other existing and future regulatory obligations, including, but not limited to, costs relating to air emissions including greenhouse gases, the management of ballast waters, maintenance and inspection, development and implementation of emergency procedures and insurance coverage or other financial assurance of our ability to address pollution incidents. Oil spills that occur from time to time may also result in additional legislative or regulatory initiatives that may affect our operations or require us to incur additional expenses to comply with such new laws or regulations.

These costs could have a material adverse effect on our business, results of operations, cash flows and financial condition and our available cash. A failure to comply with applicable laws and regulations may result in administrative and civil penalties, criminal sanctions or the suspension or termination of our operations. Environmental laws often impose strict liability for remediation of spills and releases of oil and hazardous substances, which could subject us to liability without regard to whether we were negligent or at fault. Under OPA, for example, owners, operators and bareboat charterers are jointly and severally strictly liable for the discharge of oil within the 200-nautical mile exclusive economic zone around the U.S.United States (unless the spill results solely from the act or omission of a third-party, an act of God or an act of war). An oil spill could result in significant liability, including fines, penalties, criminal liability and remediation costs for natural resource damages under international and U.S. federal, state and local laws, as well as third-party damages, including punitive damages, and could harm our reputation with current or potential charterers of our tankers. We are required to satisfy insurance and financial responsibility requirements for potential oil (including marine fuel) spills and other pollution incidents. Although we have arranged insurance to cover certain environmental risks, there can be no assurance that such insurance will be sufficient to cover all such risks or that any claims will not have a material adverse effect on our business, results of operations, cash flows, financial condition and available cash.

RecentIt should be noted that the United States are currently experiencing changes in its environmental policy, the results of which have yet to be fully determined. For example, in April 2017, the U.S. President signed an executive order regarding environmental regulations, specifically targeting the U.S. offshore energy strategy, which may affect parts of the maritime industry and our operations (although portions of this executive order are being challenged in litigation) . Furthermore, recent action by the IMO'sIMO’s Maritime Safety Committee and U.S.United States agencies indicate that cybersecurity regulations for the maritime industry are likely to be further developed in the near future in an attempt to combat cybersecurity threats. For example, cyber-risk management systems must be incorporated by ship-owners and managers by 2021. This might cause companies to cultivate additional procedures for monitoring cybersecurity, which could require additional expenses and/or capital expenditures. However, the impact of such regulations is hard to predict at this time.

Non-compliance with the ISM Code and, other IMO or National or Regional regulations / conventions may subject the shipowner or bareboat charterer to increased liability, may lead to decreases in, or invalidation of, available insurance coverage for affected vessels and may result in the denial of access to, or detention in, some ports. The U.S. Coast Guard or the USCG and E.U. authorities have indicated that vessels not inAuthorities enforce compliance with the ISM Code by the applicable deadlines will be prohibitedand ISPS Codes and prohibit non-compliant vessels from trading in U.S. and E.U. ports.ports.This could have a material adverse effect on our future performance, results of operations, cash flows and financial position. The IMO continues to review and introduce new regulations. It is impossible to predict what additional regulations, if any, may be passed by the IMO and what effect, if any, such regulations might have on our operations.

Due to concern over the risk of climate change, a number of countries and the IMO have adopted, or are considering the adoption of, regulatory frameworks to reduce greenhouse gas emissions. These regulatory measures may include, among others, adoption of cap and trade regimes, carbon taxes, increased efficiency standards and incentives or mandates for renewable energy. More specifically, on October 27, 2016, the International Maritime Organization’s Marine Environment Protection Committee ("MEPC") announced its decision concerning the implementation of regulations mandating a reduction in sulfur emissions from 3.5% currently to 0.5% as of the beginning of January 1, 2020. Additionally, in April 2018, nations at the MEPC 72 adopted an initial strategy to reduce greenhouse gas emissions from ships. The initial strategy identifies ¯levels of ambition to reducing greenhouse gas emissions, including (1) decreasing the carbon intensity from ships through implementation of further phases of the EEDI for new ships; (2) reducing carbon dioxide emissions per transport work, as an average across international shipping, by at least 40% by 2030, pursuing efforts towards 70% by 2050, compared to 2008 emission levels; and (3) reducing the total annual greenhouse emissions by at least 50% by 2050 compared to 2008 while pursuing efforts towards phasing them out entirely. The European Union on the other hand has indicated that it intends to accelerate its plans to include shipping into the emissions trading scheme.

In addition, although the emissions of greenhouse gases from international shipping currently are not subject to the Kyoto Protocol to the United Nations Framework Convention on Climate Change, which required adopting countries to implement national programs to reduce emissions of certain gases, or the Paris Agreement (Discussed(discussed further below), a new treaty may be adopted in the future that includes restrictions on shipping emissions. Compliance with changes in laws, regulations and obligations relating to climate change could increase our costs related to operating and maintaining our vessels and require us to install new emission controls, acquire allowances or pay taxes related to our greenhouse gas emissions or administer and manage a greenhouse gas emissions program. Revenue generation and strategic growth opportunities may also be adversely affected.

Adverse effects upon the oil and gas industry relating to climate change, including growing public concern about the environmental impact of climate change, may also adversely affect demand for our services. For example, increased regulation of greenhouse gases or other concerns relating to climate change may reduce the demand for oil and gas in the future or create greater incentives for use of alternative energy sources. In addition, the physical effects of climate change, including changes in weather patterns, extreme weather events, rising sea levels, scarcity of water resources, may negatively impact our operations. Any long-term material adverse effect on the oil and gas industry could have a significant financial and operational adverse impact on our business that we cannot predict with certainty at this time.

We evaluate the recoverable amount as the higher of fair value less costs to sell andor value in use. If the recoverable amount is less than the carrying amount of the vessel, the vessel is deemed impaired. The carrying values of our vessels may not represent their fair market value at any point in time because the new market prices of secondhand vessels tend to fluctuate with changes in charter rates and the cost of newbuildings. For the years endedyear December 31, 2016 and 2015,2018, we evaluated the recoverable amount of our vessels and we did not recognize an impairment loss. Any impairment charge incurredThe carrying value of each of our vessels does not necessarily represent its fair market value or the amount that could be obtained if the vessel were sold. Our estimates of market values for our vessels assume that the vessels are all in good and seaworthy condition without need for repair and, if inspected, would be certified as being in class without notations of any kind. Our estimates are based on the estimated market values for vessels received from independent ship brokers and are inherently uncertain. In addition, because vessel values are highly volatile, these estimates may not be indicative of either the current or future prices that we could achieve if we were to sell any of the vessels. We would not record a resultloss for any of further declinesthe vessels for which the fair market value is below its carrying value unless and until we either determine to sell the vessel for a loss or determine that the vessel is impaired. Factors that we considered in our estimate are described in the Critical Accounting policies.

In developing estimates of future cash flows, we must make assumptions about future performance, with significant assumptions being related to charter rates, could negatively affect ourship operating expenses, utilization, drydocking requirements, residual value and the estimated remaining useful lives of the vessels. These assumptions are based on historical trends and/or on future expectations. Specifically, in estimating future charter rates or service contract rates, management takes into consideration estimated daily rates for each asset over the estimated remaining lives. In the past, we have used a fixed cut of 10 years to define a shipping cycle. As management is assessing continuously the resilience of its projections to the business financial condition, operating results orcycles that can be observed in the trading pricetanker market, it concluded that a business cycle approach provides a better long-term view of our ordinary shares.

If our vessels suffer damage, they may need to be repaired at a drydocking facility. The costs of drydock repairs and maintenance are unpredictable and may be substantial. We may have to pay drydocking costs that our insurance does not cover in full. The loss of revenues while these vessels are being repaired and repositioned, as well as the actual cost of these repairs, may adversely affect our business and financial condition. In addition, space at drydocking facilities is sometimes limited and not all drydocking facilities are conveniently located. We may be unable to find space at a suitable drydocking facility or our vessels may be forced to travel to a drydocking facility that is not conveniently located to our vessels'vessels’ positions. The loss of earnings while these vessels are forced to wait for space or to travel to more distant drydocking facilities may adversely affect our business and financial condition. Further, the total loss of any of our vessels could harm our reputation as a safe and reliable vessel owner and operator. If we are unable to adequately maintain or safeguard our vessels, we may be unable to prevent any such damage, costs, or loss which could negatively impact our business, financial condition, results of operations and available cash.

In addition, international shipping is subject to various security and customs inspection and related procedures in countries of origin and destination and trans-shipment points. Inspection procedures can result in the seizure of the cargo and/or our vessels, delays in the loading, offloading or delivery and the levying of customs duties, fines or other penalties against us. It is possible that changes to inspection procedures could impose additional financial and legal obligations on us. Furthermore, changes to inspection procedures could also impose additional costs and obligations on our customers and may, in certain cases, render the shipment of certain types of cargo uneconomical or impractical. Any such changes or developments may have a material adverse effect on our business, results of operations, cash flows, financial condition and available cash.

Our FSO activities are subject to various risks, including delays, cost overruns, unavailability of supplies, employee negligence, defects in machinery, collisions, service damage to vessels, damage or loss to freight, piracy, war, political tensions or strikes. In case of delays in delivering FSO under service contract to the end-user, contracts can be amended and/or cancelled.canceled. Moreover, the operation of FSO vessels is subject to the inherent possibility of maritime disasters, such as oil spills and other environmental accidents, and to the obligations arising from the ownership and management of vessels in international trade. We have established current insurance against possible accidents and environmental damage and pollution that complies with applicable law and standard practices in the sector. However, there is no guarantee that such insurance will remain available at rates which are regarded as reasonable by us or that such insurance will remain sufficient to cover all losses incurred or the cost of each compensation claim made against us, or that ourus. Our insurance policies willdo not cover the loss of income resulting from a vessel becoming non-operational. Should compensation claims be made against us, our vessels may be impounded or subject to other judicial procedures, which would adversely affect our results of operations and financial condition.

The majority of our employees (land-based and offshore) are represented by collective bargaining agreements in Belgium, Greece, France and the Philippines. For a limited number of vessels, the employment of onboard staff is based on internationally negotiated collective bargaining agreements. In addition, many of these represented individuals are working under agreements that are subject to salary negotiation. These negotiations could result in higher personnel costs, other increased costs or increased operating restrictions that could adversely affect our financial performance. In addition, as part of our legal obligations, we are required to contribute certain amounts to retirement funds and pension plans (with insurance companies or integrated in a national social security scheme) and are bound to legal restrictions in our ability to dismiss employees. Any disagreements concerning ordinary or extraordinary collective bargaining may damage our reputation and the relationship with our employees and lead to labor disputes, including work stoppages, strikes and/or work disruptions, which could hinder our operations from being carried out normally, and if not resolved in a timely cost-effective manner, could have a material effect on our business.

In June 2016, a majority of voters in the past, political instabilityU.K. elected to withdraw from the EU in a national referendum (informally known as "Brexit"), and in March 2017, the government of the U.K. formally initiated the process which resulted in a formal withdrawal from the EU on 31 January 2020. There remains significant uncertainty about the future relationship between the U.K. and the EU. The withdrawal has also resulted in attacksgiven rise to calls for the governments of other EU member states to consider withdrawal. These developments, or the perception that any of them could occur, have had and may continue to have a material adverse effect on vessels, mining of waterways and other efforts to disrupt international shipping, particularly in the Arabian Gulf region. Acts of terrorism and piracy have also affected vessels trading in regions such as the South China Seaglobal economic conditions and the Gulfstability of Aden offglobal financial markets, and may significantly reduce global market liquidity and restrict the coastability of Somalia.key market participants to operate in certain financial markets. Any of these occurrencesfactors could depress economic activity and restrict our access to capital, which could have a material adverse impacteffect on our business and on our consolidated financial condition,position, results of operations and available cash.our ability to pay distributions. Additionally, Brexit, or similar events in other jurisdictions, could impact global markets, including foreign exchange and securities markets; any resulting changes in currency exchange rates, tariffs, treaties and other regulatory matters could in turn adversely impact our business and operations.

Sanctions and embargo laws and regulations vary in their application, as they do not all apply to the same covered persons or proscribe the same activities, and such sanctions and embargo laws and regulations may be amended ,strengthened or strengthenedweakened over time. In 2010, the U.S. enacted the Comprehensive Iran Sanctions Accountability and Divestment Act, or "CISADA," which expanded the scope of the Iran Sanctions Act. Among other things, CISADA expands the application of the prohibitions on companies such as ours and introduces limits on the ability of companies and persons to do business or trade with Iran when such activities relate to the investment, supply or export of refined petroleum or petroleum products.

Although we believe that we have been in compliance with all applicable sanctions and embargo laws and regulations, and intend to maintain such compliance, there can be no assurance that we will be in compliance in the future, particularly as the scope of certain laws may be unclear and may be subject to changing interpretations, and with respect to the JCPOA, the U.S. retains the authority to revoke the aforementioned relief if Iran fails to meet its commitments under the JCPOA.interpretations. Any such violation could result in fines, penalties or other sanctions that could severely impact our ability to access U.S. capital markets and conduct our business and could result in some investors deciding, or being required, to divest their interest, or not to invest, in us. In addition, certain institutional investors may have investment policies or restrictions that prevent them from holding securities of companies that have contracts with countries identified by the U.S. government as state sponsors of terrorism. The determination by these investors not to invest in, or to divest from, our ordinary shares may adversely affect the price at which our ordinary shares trades.trade. Additionally, some investors may decide to divest their interest, or not to invest, in our company simply because we do business with companies that do business in sanctioned countries.countries or territories. Moreover, our charterers may violate applicable sanctions and embargo laws and regulations as a result of actions that do not involve us or our vessels, and those violations could in turn negatively affect our reputation. In addition, our reputation and the market for our securities may be adversely affected if we engage in certain other activities, such as entering into charters with individuals or entities in countries or territories subject to U.S. sanctions and embargo laws that are not controlled by the governments of those countries or territories, or engaging in operations associated with those countries or territories pursuant to contracts with third-parties that are unrelated to those countries or territories or entities controlled by their governments. Investor perception of the value of our ordinary shares may also be adversely affected by the consequences of war, trade war, the effects of terrorism, civil unrest and governmental actions in these and surrounding countries.

We expect that our vessels will call in ports where smugglers attempt to hide drugs and other contraband on vessels, with or without the knowledge of crew members. To the extent our vessels are found with contraband, whether inside or attached to the hull of our vessel and whether with or without the knowledge of any of our crew, we may face governmental or other regulatory claims which could have an adverse effect on our business, results of operations, cash flows and financial condition.

Crew members, suppliers of goods and services to a vessel, shippers of cargo, secured lenders, and other parties may be entitled to a maritime lien against the relevant vessel for unsatisfied debts, claims or damages. In many jurisdictions, a maritime lien holder may enforce its lien by arresting or attaching a vessel through foreclosure proceedings. The arrest or attachment of one or more of our vessels could interrupt our business or require us to pay large sums of money to have the arrest lifted, which would have a negative effect on our cash flows.

In addition, in some jurisdictions, such as South Africa, under the "sister ship"“sister ship” theory of liability, a claimant may arrest both the vessel which is subject to the claimant'sclaimant’s maritime lien and any "associated"“associated” vessel, which is any vessel owned or controlled by the same owner. Claimants could try to assert "sister ship"“sister ship” liability against one vessel in our fleet for claims relating to another of our ships.

A government could requisition one or more of our vessels for title or hire. Requisition for title occurs when a government takes control of a vessel and becomes the owner. Also, a government could requisition our vessels for hire. Requisition for hire occurs when a government takes control of a vessel and effectively becomes the charterer at dictated charter rates. Generally, requisitions occur during a period of war or emergency. Government requisition of one or more of our vessels may negatively impact our business, financial condition, results of operations and available cash.
