II as a blank check company to acquire, through a merger, share exchange, asset acquisition, stock purchase, plan of arrangement, recapitalization, reorganization or other similar business combination, one or more businesses or entities.

On July 8, 2015, we completed a series of mergers whereby Lindblad Expeditions, Inc., a New York corporation, became our wholly-owned subsidiary. As consideration for the mergers, the total purchase price consisted of an aggregate of (i) $90.0 million in cash (a portion of which was paid as transaction bonuses) and (ii) 20,017,787 shares of our common stock. We also assumed outstanding stock options and converted such options into options to purchase an aggregate of 3,821,696 shares of our common stock with an exercise price of $1.76 per share.

Immediately following the mergers, we changed our name to Lindblad Expeditions Holdings, Inc.

We also have two new 236-foot, 100-passenger cruise vessels, being constructed with delivery expected in the second quarter of 2017 and the second quarter of 2018, respectively, as well as a definitive purchase agreement to acquire a vessel to replace one of our six owned expedition ships. Our expedition ships are customized, nimble and intimately-scaled vessels that are able to venture where larger cruise ships cannot, thus allowing us to offer truly authentic, up-close experiences in the planet’s wild and remote places and capitals of culture. Many of these expeditions involve travel to remote places with limited infrastructure and ports (such as Antarctica and the Arctic) or, including places that are best accessed by a ship (such as the Galápagos, Alaska, Baja’s Sea of Cortez, Costa Rica and Panama), and foster active engagement by guests. Each expedition ship is designed to be comfortable and inviting, while being fully equipped with state-of-the-art tools for in-depth exploration. In addition to our sea-based expeditions, we offer land-based, eco-conscious expeditions from Antarctica to Zambia primarily through our ownership of Natural Habitat, Inc. (“Natural Habitat”).

We collaborate with National Geographic on voyageexpedition planning to enhance the guest experience by having National Geographic experts, including photographers, writers, marine biologists, naturalists, field researchers and film crews, join our expeditions. Guests have the ability to interface with these experts through lectures, excursions, dining and other experiences throughout their voyage.expedition.

By providing suchdemographic category. The quality of our offerings which we work continuously to innovate and further elevate, we have been ablehas enabled us to achieve and maintain premium pricing in the market instead of pursuing the type of discounting in which most large cruise lines that are focused on the broader market engage. Our product offering, value proposition and differentiated pricing approach support ourenable us to achieve high net yields and occupancy rates.

Our business benefits from significant visibility into future revenues, as our guests generally plan and book their voyages far in advance of their departure dates. As of March 7, 2016, 85%February 26, 2018, 90% of Lindblad’sthe Lindblad segment’s expected guest ticket revenues for 2016 had2018 have been booked.

We choose to visit geographic areas based upon many factors, including weather, marine conditions, migration patterns and various natural phenomena. In the northern hemisphere summer months, we primarily visit the High Arctic regions of the world, the Canadian Maritimes, Europe, the South Pacific and Alaska. In the northern hemisphere winter months, we primarily travel to Antarctica, South America, Costa Rica, Baja California and the Caribbean. The Galápagos Islands are a year-round destination offering a diverse variety of marine, land and airborne wildlife.

Lindblad Expeditions, Ships and Voyages

Itineraries

Currently we operate a fleet of seven vessels owned and five chartered ships to provide our signature marine-based adventures to over 40 destinations on seven continents of the world. We have extensive experience operating in the Galápagos Islands, Alaska, Antarctica and the Arctic, with the Lindblad family having been among the first to bring non-scientist travelers to these regions. We currently operate two vessels in the Galápagos, providing week-long itineraries throughout the year. We operate two polar vessels that serve in Antarctica during the northern hemisphere winter, in the Arctic during the northern hemisphere summer and various destinations during the intermediate months, offering itineraries that last from five to 24 days. We also operate three ships in Alaska during the summer months that travel south along the U.S. coastline to the Sea of Cortez and to Belize, Guatemala, Costa Rica and Panama for the winter. In addition, we charter five vessels for seasonal itineraries in the Amazon, Scotland, the Caribbean, the Mediterranean, Cuba, Cambodia and Vietnam.

We place a strong focus on innovation, which we seek to achieve by introducing new expedition options and continuously making improvements to our fleet and voyage experiences as new technology or operating procedures are developed. We make deployment decisions with the goal of optimizing the overall profitability of our portfolio, with these decisions generally made 18 to 24 months in advance. We have operated above 87% occupancy rate for each of the years ended December 31, 2017, 2016 and 2015, indicating strong consumer interest in our offerings. Adding new capacity will allow us to expand our inventory of existing itineraries and expand into new markets and destinations.

Ship Repair and Maintenance

In addition to routine repairs and maintenance performed on an ongoing basis and in accordance with applicable requirements, each of our expedition ships is taken out of service for a scheduled deeper maintenance period to conduct repairs and improvements. We maintain our fleet in accordance with applicable regulations, international conventions and insurance requirements. This includes regularly scheduled maintenance, periodic inspections, drydocking, wetdocking and overhaul. In addition, renovations and replacements of various vessel elements are part of the ongoing process of maintaining the vessels to a high standard.

For U.S. flagged ships, the statutory requirement is an annual docking and U.S. Coast Guard inspections, normally conducted in drydock. Internationally flagged ships have scheduled dockings approximately every 12 months, for a period of up to three to six weeks. Drydock interval and required inspections are statutory requirements controlled under chapters of the International Convention of the Safety of Life at Seas (“SOLAS”) and Classification Society instructions. Under these regulations, passenger ships must be inspected in drydock twice in five years, with the maximum duration between each drydock inspection not to exceed three years, and an underwater hull inspection is required annually. To the extent practicable each ship’s crew and hotel staff remain with the ship during docking periods and assist in performing repair and maintenance work. We do not earn revenue while ships are in dock. Accordingly, dockings are typically planned during non-peak demand periods to minimize the adverse effect on revenue that results from ships being out of service.

Guest Activities and Services

We provide our guests the opportunity and the tools to be active and engaged explorers. Our vessels carry a variety of equipment for exploration which, depending on the ship and destination, may include Zodiacs for water-based activities and quick transfers to shore, kayaks for personal exploration, motorized skiffs, an underwater camera, a remotely operated vehicle, a video microscope to study some of the smallest organisms of the marine ecosystem, a crow’s nest camera atop a ship’s mast, hydrophones for listening to vocalizations of marine mammals, snorkeling gear, scuba gear and wetsuits. An experienced and knowledgeable expedition staff leads guests in exploration while Zodiac riding, hiking onshore, paddling on the water or observing wildlife from ashore or onboard the ship. All voyages feature a certified photo instructor onboard and many include photographers from National Geographic.

Our ships allow guests to be close to wild nature, but at the same time, enjoy a high level of comfort, convenience and safety. High-quality dining is an integral part of our expedition experience with influences and flavors that reflect the regions being explored, along with traditional fare. Food prepared aboard is sourced locally whenever practicable from sustainable providers. Seating is open and the atmosphere is relaxed. Our ships offer a range of services and amenities which allow our guests to travel in comfort. Depending on the ship, these may include a fitness center, a spa offering a variety of treatments, a photo kiosk for photographers to edit and sort photos, 24-hour beverage service, internet connection, laundry facilities and a doctor on call.

We offer to handle virtually all travel aspects related to guest reservations and transportation, simplifying the planning and booking process for our guests. We also provide guests the opportunity to purchase pre- and post-expedition extensions or services that may include additional hotel nights, air travel, private transfers, excursions, land travel packages and travel protection insurance.

Competitive Strengths

Our management team believes the following characteristics of our business model will enable us to successfully execute our strategy:

Expertise and Name Recognition

Our leadership and expertise today isare built on the Lindblad family’s decades of experience in expedition adventure travel. Sven-Olof Lindblad, the founder, President and Chief Executive Officer of the Company, comes from a rich expedition heritage. The International Association of Antarctica Tour Operators, which was established in 1991, believes that the concept of expedition cruising, coupled with education as a major theme, began when Lars-Eric Lindblad, Mr.Sven-Olof Lindblad’s father, led the first traveler’s expedition to Antarctica in 1966. Lars-Eric Lindblad has also been recognized byThe New York Times,Travel + LeisureMagazine and other publications for his vision and leadership in developing what is today known as expedition travel. Believing that educated people who saw things with their own eyes would be a potent force for the preservation of the places they visited, Lars-Eric Lindblad worked to promote conservation and restoration projects worldwide. Mr.Sven-Olof Lindblad founded Lindblad in 1979, expanding the legacy of his father by providing expanded marine experiences around the world.

Under Mr. Lindblad’s leadership, we have led innovation in the expedition adventure travel industry. We pioneered expeditions in the High Arctic and Baja California’s Sea of Cortez and created what we view as the most innovative and in-depth expedition program in Alaska. We initiated the use of kayaks for active exploration in the Polar Regions and in the Galápagos, a feature which is now available on all of our expeditionsowned vessels to enable personal, water-level encounters with nature. We were also one of the first to develop an undersea exploration program as part of a small ship expedition utilizing state-of-the-art equipment and technology.

Competitive Strengths

Our management team believes the following characteristics of our business model will enable us to successfully execute our strategy:

Expertise and Name Recognition

For over 35 years, we have been offering expedition cruising, known for facilitating guests’ access to interpersonal educational experiences in remote places. As a pioneer in the expedition adventure travel sector, we have established deep expertise and knowledge of operating expedition cruises in extreme locations. We have earned awards and honors from various representatives of the travel industry, including recognition for the quality of our offerings and our support for conservation and sustainable tourism. Some of the awards we have earned are as follows:

In 2015, we were awarded the Legacy in Travel Philanthropy Award by Tourism Cares, the charitable arm of the travel and tourism industry, recognizing our longstanding commitment to environmental conservation. We were also named the 2015 World’s Leading Green Cruise Line by the World Travel Awards.

Also in 2015,Conde Nast Traveler rated us as one of the Top Small Ship Cruise Lines for the second consecutive year. We have also been named to theTravel + LeisureWorld’s Best List for Small-Ship Cruise Lines six times since 2008.

In 2013, we won theTravel + Leisure Global Vision Award for Leadership. This award recognized travel operators with a focus on extraordinary ways that travelers can give back to the places they visit.

Virtuoso awarded us our Sustainable Tourism Leadership Supplier Award in 2013, an award honoring outstanding leadership and commitment to sustainable tourism principles and practices among Virtuoso suppliers.

When customers select an expedition provider for the types of journeys that we offer, we believe that being known as a trusted brand in the market is a significant competitive strength.

Compelling Expedition Offerings

Our brand is known for delivering voyages that offer in-depth exploration opportunities in locations around the world. Expeditions are operated on intimately-scaled ships with capacities ranging between 28 and 148 guests, fostering a friendly atmosphere on board and extensive interaction between guests, crew and the teams of world classworld-class scientists, naturalists, researchers and photographers that participate in the expeditions. The vessels are nimble and can access locations that are unattainable for large cruise ships, allowing for in-depth exploration itineraries and viewpoints. The ships are customized to provide our signature adventure experiences and activities, such as kayaking among Antarctic icebergs to view penguins or traveling on a Zodiac for an up-close encounter with a whale.

We are continuously focused on maintaining and elevating the guest experience and identifying new opportunities to help people discover the wonders of the world. We believe that our expedition offerings and our track record of innovation represent significant competitive advantages for us.

Strong Financial Profile

Our business model allows us to generate consistent free cash flow with high revenue visibility. Our guests plan and book their voyagesexpeditions on average nine months in advance, with a deposit due upon booking, providing us insight into future revenue and a source of cash flow. Based on our product offerings, we are able to support premium pricing with minimal discounting and benefit from low requirements for maintenance capital expenditures, minimal working capital needs and favorable tax attributes. For the years ended December 31, 2015, 2014 and 2013, we achieved an Adjusted EBITDA of $46.8 million, $44.6 million and $36.5 million, respectively, which represents a compounded annual growth rate of 13.2% since 2013.

We also have a strong cash position, providing us with ample financial flexibility to pursue growth opportunities through investment in new vessels, new charters, tactical land-based products or potential acquisitions of ships or other operators, while still maintaining a prudent capital structure.

Significant Growth Opportunities

We believe affluent Americans aged 50 and above defineview their retirement as “a time to travel and explore new places,” favoring travel experiences such as expedition cruising. This has led to strong growth in the specialty cruise segment and we believe these trends will continue. We plan to expand the number of ships in our fleet, including chartered vessels from 10 to 13 over the next several years, and have signedthree years. This includes two contracted vessels, a construction agreement to build two new coastal vessels withvessel and a new polar ice class vessel. The expected deliveries on targetof the first two vessels are scheduled for the secondfourth quarter of 20172018 and 2018,first quarter of 2020, respectively. Additionally, we believe that our platform will beis well positioned to opportunistically seek accretive purchases of operators that lack scale and capital, further extending our growth prospects.

Strategic Alliance with National Geographic

Experienced Management Team

We are led bybenefit from a management team comprisedlongstanding relationship with the National Geographic Society, one of individuals drawingthe world’s leading proponents of eco-tourism and natural history. The strategic alliance, which began in 2004, is built on our shared interest in exploration, research, technology and conservation. Founded in 1888, the National Geographic Society is one of the largest non-profit scientific and educational institutions in the world with interests ranging from geography, archaeology and natural science, to the promotion of environmental and historical conservation. Working to inspire, illuminate and teach, National Geographic reaches more than 600 million people a diversemonth through a wide range of media, including print, TV and digital. The National Geographic name has significant value for use in connection with travel-related goods and services. The Lindblad/National Geographic alliance includes a co-selling and co-marketing arrangement through which National Geographic promotes our offerings in its marketing campaigns across web-based, email, print and other marketing platforms and sells our expeditions through its internal travel division. The National Geographic sales channel represented approximately 25% of our guest ticket revenues for the year ended December 31, 2017. We believe that the alliance with National Geographic provides us with a substantial competitive advantage in the expedition market based on the brand enhancement, expanded marketing reach and the relationship with National Geographic’s naturalists and photographers.

Through this alliance, we collaborate with National Geographic on exploration, research, technology and conservation in order to provide travel experiences and disseminate geographic knowledge basearound the globe.

Industry and Market

We believe the specialty and small ship cruising segment of the cruise industry demonstrates the following positive fundamentals:

Favorable Characteristics of Cruise Industry

Cruising is a vacation alternative with broad appeal, as it offers a wide range of products, destinations and experiences to suit the preferences of vacationing consumers of all ages, wealth levels and nationalities. The multi-night global cruise industry is predominantly made up of large ships of over 1,000 berths with per diem pricing of $100 to $250 per person, which is designed to reach a mass market audience. This market segment has grown significantly but still remains relatively small compared to the broader global vacation industry, reflecting significant room for growth. According to the Global Economic Contribution of Cruise Tourism 2014 by Business Research & Economic Advisors, published in October 2015, the cruise industry has experienced steady growth over the past 30 years. Between 2004 and 2014, demand for cruising worldwide increased from 13.1 million passengers to 22.0 million passengers, an increase of 68%, whereas over a similar period, global tourism has only risen by 45%. According to a Cruise Lines International Association (“CLIA”) 2015 State of the Cruise Industry Report and a STR Global census database, there were about 482,000 beds in the global cruise industry in 2014, which is less than 4% of the number of worldwide hotel rooms as of December 2015. Cruising is considered a well-established vacation sector in the North American market, a growing sector over the long-term in the European market and a developing but promising sector in several other markets.

Strong Growth in Specialty and Small Ship Cruising Segment

The specialty and small ship cruising segment of the cruise industry is characterized by the smallest vessel size, unique itineraries, active adventures, gourmet culinary programs, highly personalized service and a more inclusive offering. These exclusive attributes, combined with limited supply growth and a growing worldwide target population, provide specialty and small ship cruising operators with significant pricing leverage as compared to the other segments of the cruise industry.

The specialty cruise segment has demonstrated strong growth as consumers increasingly prefer experiences over other forms of discretionary spending. According to CLIA,Cruise Lines International Association (“CLIA”), specialty cruises grew by 21% annually from 2009 to 2014. In a December 20152016 survey of CLIA-member travel agents, 83% expect75% expected increased bookings in 20162017 from the prior year, with 40%33% of the agents anticipating growth of 10% or greater. Despite this consistent growth, we believe the specialty cruise industry still has low penetration levels compared to similar land-based vacations, which we believe highlights the continued growth potential for the specialty cruise market.

The specialty cruise segment includes expeditions to destinations around the world, such as those included in our itineraries. This sub-segment also benefits from positive growth of the broader adventure travel industry. Adventure travel grew 65% year-over-year from 2009 to 2012 into a $263 billion industry, according to the 2013 Adventure Tourism Market Study conducted by George Washington University and the Adventure Travel Trade Association. This growth was partly attributed to a 59% increase in the appeal of adventure trips, and a 60% increase in average spending per adventure trip, driven partly by an increase in the average trip length from seven days in 2009 to nine days in 2012.

Attractive Target Market Demographics

Our offerings appeal to a wide range of travelers, both individuals and families, but affluent individuals in the U.S. aged 50 years or older represent our largest segment.demographic category. We believe that our small ship expedition offerings, with itineraries that promote up-close encounters with wildlife, nature and culture, have significant appeal to this target market. These individuals are also generally near-retirement or retired and have the leisure time and disposable income available to pursue the type of activities that we provide. Based on the U.S. Census Bureau’s 20142015 National Projections, the age group of 4550 years and older numbered approximately 130111 million individuals in 2014,2015, or approximately 41%35% of the U.S. population, and is expected to grow to approximately 140120 million in 2020, an increase of approximately 8%. In comparison, over the same time period the age group of 18 years and younger is projected to increase by approximately 1% and the age group of 18 year to 44 years is projected to increase by approximately 4%.

High Barriers to Entry

The adventure travel and specialty cruise industries in which we operate are characterized by high barriers to entry, which include the expertise and experience required to operate safely and effectively in remote locations, the existence of well-established and trusted brands, the time and personal relationships required to develop strong networks of experts to lead and support expeditions, the cost and time required to build the strong travel agent network partnerships necessary for success, local permits or licenses required to operate in a diverse range of geographies, large capital expenditures and operational insight required to build new and sophisticated ships suited for such specialized activities.

Competition

We compete with a number of cruise lines with competition varying by destination. The growthmarket is fragmented and primarily comprised of private operators. The primary competitors that operate in the geographic regions we serve include Silversea Expeditions, Quark Expeditions, Compagnie du Ponant, Hurtigruten and Un-Cruise Adventures. For our land-based expeditions, we compete with a variety of companies offering itineraries in the countries in which we operate. These range from small private operators to larger companies operating across multiple countries. Some of our larger competitors include Abercrombie & Kent, Overseas Adventure Travel and GeoEx. We also compete with other vacation alternatives such as land-based resort hotels and sightseeing destinations for guests’ leisure time. Companies within the vacation market are dependent on consumer discretionary spending.

The cruise industry depends, however, on consumers’ discretionary spending,in general and in the event that consumers’ disposable income or consumer confidence decreases asexpedition cruise industry specifically are characterized by high barriers to entry, including the existence of several established and recognizable brands, the large investment required to build a result of an economic downturn or other factors, demand for cruises could decrease. See “Risk Factors – Risks Relatednew, sophisticated ship, the long lead time necessary to Our Businessconstruct new ships and Operations – Adverse worldwide economic, geopolitical or other conditions could reduce the demand for expedition cruises and adversely impact our operating results, cash flows and financial condition, including potentially impairing the value of our fleet and other assets.”limited newbuild shipyard capacity.

Business and Growth Strategies

The following are the key components of our business strategy:

Deliver Exceptional Guest Experiences

Our chief governing principle throughout the organization is to ensure that everything adds value to the guest experience. This applies to every step of the process from the first engagement with a potential guest, through the booking process and travel preparations, the actual expedition, whether onboard the vessel or off on explorations, and once back at home.

We believe that our guests do not want to be passive tourists, so our expeditions foster active engagement. Our ships are equipped with tools for exploration to get our guests out in the open for up-close forays, or to let guests see deeper into the marine or terrestrial environments surrounding them. It is our goal to provide guests with differentiated opportunities such as watchingwith an experienced expedition team that adds to the guests’ understanding and appreciation, through dedicated observation, insightful commentary and engaging presentations, weaving the expedition into a cohesive narrative. This could include an opportunity for the guest to watch a killer whale circling a seal on an ice flow,floe, while standing next to a marine biologist and an experienced nature photographer from National Geographic. An experienced expedition team adds to the guests’ understanding and appreciation, through dedicated observation, insightful commentary and engaging presentations that weave the expedition into a cohesive narrative. This intense focus on seeking to elevate the overall experience and engaging with guests has resulted in highly favorable customer feedback, as collected by us and as reflected in the numerous industry honors we have received.feedback. We believe that by consistently delivering exceptional experiences to our guests, we have built a highly valuable and trusted brand in the expedition cruising and land-based expedition market, which attracts a growing number of customers, and in particular, discerning and affluent guests who are prepared to pay a premium for our offerings.

High Visibility and Differentiated Revenue Management Strategy

Given the nature of our expeditions and the expectation that our guests will seek to plan such trips with substantial notice, we begin to market our voyages approximately 12 to 1824 months in advance of the departure date, depending on the destination. Guests book their trips, on average, nine months prior to sail date, paying a deposit at booking and the final payment 60 to 120 days within the date of travel, dependent upon the selected voyage. As of February 26, 2018, 90% of the Lindblad segment’s expected guest ticket revenues for 2018 has been booked. 

Unlike the large cruise line operators that serve the broader market, our product offering is inclusive of most costs and therefore the advance customer payments provide us strong visibility into future revenues and the associated cash flows. By having such visibility ofinto future business, we can more effectively manage any additional sales and marketing efforts that may be required to ensure that the programs reach their targeted occupancy levels. We do not believe in driving participation through discounting and do not generally pursue such strategies. Instead, we focus on voyage enhancements that add significant value to the product without muchsignificant incremental cost, as well as targeted marketing efforts in order to strengthen occupancy rates, if required. Based on our offerings, the targeted audience and premium pricing, our guests are generally older, more affluent and do not travel with three or four individuals in one cabin. As it is industry convention to base 100% occupancy on two persons per cabin, we may report occupancy levels that are somewhat lower than the large cruise lines serving the broader market. However, the occupancy statistics nevertheless reflect appropriately that we are operating close to full occupancy. We have achieved strong occupancy rates for the Lindblad segment in the last three years (based on two persons per cabin), specifically 91.8% in 2015, 92.9% in 2014operating at above 87% occupancy rate for the years ended December 31, 2017, 2016 and 92.4% in 2013. As of March 7, 2016, 85% of our expected guest ticket revenues for 2016 had been booked.2015.

Maximize and Grow Net Yields

We have historically achieved high net yields and continue to see opportunities for growth. Net yield is a frequently referenced metric used in the cruise industry and refers to tour revenues net of commissions and certain direct costs in a specific period divided by the number of available guest nights. Our net yields are driven by our offerings, premium pricing and ancillary guest revenue, such as pre- or post-voyage trip extensions, add-on optional activities, trip insurance and onboard spend, including spa services and alcoholic beverages. Our net yields were $985, $976 and $971 $950in 2017, 2016 and $931 in 2015, 2014 and 2013, respectively. TheseFurthermore, our historical net yield amounts reflect annual growth rates of 2.2% from 2014 to 2015 and 2.0% from 2013 to 2014. Furthermore, while our use of net yield may not be comparable to companies in the industry, our net yield in 2015 washas been significantly higher than the large scale cruise line operators. We expect to be able to continue our track record of maintaining strong pricing and growing ancillary guest revenues through increased sales focus and marketing efforts, particularly of pre- and post-voyage extensions on which we have not historically placed significant emphasis.

Elevate Brand Awareness and Loyalty

Our brand is recognizable by our guests primarily due to our heritage, decades of sales and marketing investment and long-standinglongstanding strategic alliance with National Geographic. We believe we have fostered strong guest and brand loyalty, which is evidenced by our high levels of repeat guests. In 2015, 37%2017, 41% of guests booked through our U.S. office were past guests. We have closely aligned our marketing efforts with National Geographic to maximize impact in the marketplace and have engaged in a co-branding strategy with respect to our owned vessels. In addition, we are recognized as a leader in promoting the issue of conservation of the planet and encourage our guests to become engaged through the Lindblad Expeditions – National Geographic Joint Fund for Exploration and Conservation (“LEX-NG Fund”). In the past, we have organized high levelhigh-level meetings in the Arctic, Antarctic, Galápagos and Baja California to put a spotlight on key environmental issues in conjunction with organizations such as the Aspen Institute, TED and the World Wildlife Fund.WWF. These efforts help to build our brand and network of relationships and enhance our thought leadership. We will continue to focus on ensuring that each of our guests associates our brand with high-quality overseasmarine based adventure vacation experiences.

We source our business through a combination of direct selling, travel agency networks and our strategic alliance with National Geographic. We invest in maintaining strong relationships with our key travel agency network partners and seek to maintain commission rates and incentive structures that are competitive within the marketplace.

The National Geographic relationship also serves as a channel for bookings. Our alliance with National Geographic includes a co-selling and co-marketing arrangement through which National Geographic promotes our offerings in its marketing campaigns across web-based, email, print and other marketing platforms and sells our expeditions through its internal travel divisions. The National Geographic channel represented approximately 25%, 27% and 24% of guest ticket revenues for 2017, 2016 and 2015, respectively.

We maintain an active presence on numerous social media platforms, focusing primarily on those with the greatest reach to our target demographic. In addition, we routinely feed content to National Geographic’s social media platforms, which extend the reach of our brand significantly.

Disciplined Expansion

We are focused on growing our business in a prudent and disciplined manner. When evaluating various strategies for expansion of guest capacity, we consider closely the expected return on invested capital and the range of possibilities, such as a newbuild program, adding selected charters and the acquisitions of existing ships or small operators, such as the 2013 acquisition of Fillmore Pearl Holdings Ltd. and its subsidiaries, including the owner of the vessel that was subsequently named National Geographic Orion.operators. We currently have twoa new coastal vessels on ordervessel under construction scheduled for delivery in 20172018 and 2018, respectively.a new polar ice class vessel under construction scheduled for delivery in 2020. We also have options for two additional polar ice class vessels. We believe that we have ample capital and financial flexibility to fund this investment and management considers it to be an important step to meet increasing demand for our offerings.

Strategic Alliance with National Geographic

We benefit from a strategic alliance with National Geographic, one of the world’s leading proponents of eco-tourism and natural history. The strategic alliance, which began in 2004, is built on our shared interest in exploration, research, technology, and conservation. Since 1888, National Geographic has enabled people to explore the world through its magazines and, more recently, its television programs, website and social media. It is one of the largest non-profit scientific and educational institutions in the world with interests ranging from geography, archaeology and natural science, to the promotion of environmental and historical conservation. Working to inspire, illuminate and teach, National Geographic reaches more than 600 million people a month through a wide range of media, including print, TV and digital. The National Geographic name has significant value for use in connection with travel-related goods and services. The Lindblad/National Geographic alliance includes a co-selling and co-marketing arrangement through which National Geographic promotes our offerings in its marketing campaigns across web-based, email, print, and other marketing platforms and sells our expeditions through its internal travel division. The National Geographic sales channel represents approximately 24% of our guest ticket revenues. We believe that the alliance with National Geographic provides us with a substantial competitive advantage in the expedition market based on the brand enhancement, expanded marketing reach and the relationship with National Geographic’s naturalists and photographers.Operations

Through this alliance, we collaborate with National Geographic on exploration, research, technology, and conservation in order to provide travel experiences and disseminate geographic knowledge around the globe. The Lindblad/National Geographic alliance is set forth in (i) an Alliance and License Agreement and (ii) a Tour Operator Agreement.

Alliance and License Agreement. Pursuant to the Alliance and License Agreement, we and National Geographic have agreed to collaborate to identify key destinations and program enhancements as well as to develop marketing strategies, joint loyalty programs and materials for our expeditions in exchange for royalty payments from us. The royalty amount is calculated based upon a percentage of ticket revenue less travel agent commission, including the revenue received from cancellation fees and any revenue received for the sale of voyage extensions. As part of the agreement, National Geographic has granted us a (i) non-exclusive license to use certain licensed property (including licensed content and licensed marks, which include but are not limited to National Geographic’s name and images) for the advertising and promotion of certain expeditions in the U.S., its territories and possessions, Australia and New Zealand (the “Territory”) and (ii) a non-exclusive license to use the licensed property in association with our name, trademarks, services marks, and logos in connection with promotional and public relations communications in the Territory relating to certain expeditions to destinations worldwide. The agreement also provides us with a non-exclusive, non-transferable right and license to use the National Geographic marketing database for the purpose of promoting the sale of such expeditions.

The agreement includes a branding arrangement whereby our six owned and operated expedition cruise ships carry the National Geographic name. The names of the National Geographic branded vessels areNational Geographic Orion, National Geographic Explorer, National Geographic Endeavour, National Geographic Islander, National Geographic Sea Lion, and National Geographic Sea Bird. We have the right to brand each future vessel we acquire under the name “National Geographic.” In addition, the agreement provides for us to use co-branded materials to showcase National Geographic as an institution on all of our National Geographic branded ships and on certain other Lindblad ships.

The agreement also provides us with access to the experts affiliated with National Geographic, including world-renowned scientists, researchers, explorers, and photographers, who participate in our voyages and provide guests, while onboard, with lectures, excursions and informal interactions. We are required to pay a stipend to National Geographic experts on a Lindblad expedition. The agreement also requires us to designate one of our employees as the National Geographic representative and to pay National Geographic 50% and 25%, respectively, of the total compensation for two employees of National Geographic that manage our relationship. Pursuant to the agreement, we are responsible for the development, administration and operation of all voyages as well as all associated expenses, including but not limited to hiring, managing and paying qualified staff.

As part of the agreement, we agreed not to enter into any agreements with Discovery Communications, Inc. or their affiliates other than with respect to the purchase of advertising media or the license of film, video or other items and National Geographic agreed not to license its marks or content to competitive cruise ships marketed within the U.S. Each party also agreed to a standard indemnification clause for negligent acts or breaches of representations and warranties in the agreement.

Each party may terminate the agreement for breaches that are not cured timely. In addition, each party may terminate the agreement if the year-on-year net revenue growth realized by us for our cruise expeditions is less than a specified percentage, provided that any exercise of such termination right is limited to the 30-day period following delivery of year-end results and is subject to 18 months prior notice. National Geographic also has the right to terminate the agreement in the event of a change of control of our company.

The agreement further provides for the support of the LEX-NG Fund administered by National Geographic. The LEX-NG Fund identifies and articulates to our guests regional issues in conservation, education, research, and community development that require financial support. In 2015, nine key areas were supported with an aggregate amount of $1.4 million. The majority of funds were donated by guests traveling aboard our fleet; National Geographic also contributed 10% of royalty payments we made to National Geographic. In some instances, matching funds have been negotiated with third parties. In connection with the merger of Lindblad and Capitol, the stockholders of Capitol prior to its initial public offering – Capitol Acquisition Management 2 LLC, L. Dyson Dryden, Lawrence Calcano, Richard C. Donaldson, and Piyush Sodha – collectively made a charitable contribution of an aggregate of 500,000 founder’s shares in Capitol to the LEX-NG Fund for no additional consideration. The LEX-NG Fund is managed jointly by one of our staff members and a National Geographic staff member, and the Board is currently comprised of four members, including Sven-Olof Lindblad, the founder, President and Chief Executive Officer of Lindblad Expeditions Holdings, Inc., and Terry Garcia, Chief Science and Exploration Officer of National Geographic Society.

Tour Operator Agreement. Pursuant to the Tour Operator Agreement, we are the exclusive provider of ocean-going ships to National Geographic marketed in the U.S., its territories and possessions, including Puerto Rico, subject to certain exceptions. For National Geographic trips that we operate, National Geographic will market the trips under the “National Geographic Expeditions” mark and, at its own cost, is responsible for product selection, marketing and providing its own experts while we, at our own cost, are responsible for the trip itinerary and operations, marketing support, staffing, customer service, administrative operations, fare collections, and other operations on the trip. As part of the agreement, we are required to pay fees to National Geographic as a percentage of the price charged to guests. Pursuant to the agreement, National Geographic granted us a license to use its trademarks in connection with the marketing of National Geographic trips. Each party may terminate the agreement for breaches of the agreement that are not cured timely. Each party also agreed to a standard indemnification clause for negligent acts.

Amendments to Alliance and License Agreements and Tour Operator Agreement in connection with the Mergers. We entered into amendments with National Geographic dated as of March 9, 2015 to each of the agreements to extend the expiration date of each agreement from December 31, 2017 until December 31, 2025 and reaffirm the continued effectiveness of the agreements notwithstanding the mergers with Capitol. The amendment to the Alliance and License Agreement also provides that we have the right to brand each vessel acquired in the future under the name “National Geographic.”

In connection with the merger on July 8, 2015, the Company, Mr. Lindblad and National Geographic entered into a Call Option agreement where Mr. Lindblad agreed to grant National Geographic an option to purchase 2,387,499 of Mr. Lindblad’s shares in the Company as consideration for the assumption of the Alliance and License agreements and the Tour Operator agreement (see Note 10 – Commitments and Contingencies for more details).

Mr. Lindblad also serves on National Geographic’s International Council of Advisors, which is composed of individuals identified by National Geographic as visionary leaders from a range of professions and industries across the globe that exemplify the intellectual curiosity and quest for adventure that has driven National Geographic’s mission since 1888. Mr. John M. Fahey, Jr., one of our directors, previously served as the Chairman and Chief Executive Officer of National Geographic.

Expedition Ships and Voyages

Itineraries

As of March7, 2016, we operated a fleet of six expedition vessels owned through our subsidiaries and four chartered ships to provide our signature marine-based adventures to over 40 destinations along all seven continents of the world. We have extensive experience operating in the Galápagos Islands, Antarctica and the Arctic, with the Lindblad family having been among the first to bring non-scientist travelers to these regions. We currently operate two vessels in the Galápagos, providing week-long itineraries throughout the year. We operate two pole-to-pole vessels that serve in Antarctica during the northern hemisphere winter, in the Arctic during the summer and various destinations during the intermediate months, offering itineraries that last from five to 24 days. We also run two ships in Alaska during the summer months that travel south along the U.S. coastline to the Sea of Cortez and to Costa Rica and Panama for the winter. In addition, we charter four vessels for seasonal itineraries in the Amazon, Scotland, the Caribbean, the Mediterranean, Cambodia, and Vietnam.

We place a strong focus on innovation, which we seek to achieve by introducing new expedition options and continuously making improvements to our fleet and voyage experiences as new technology or operating procedures are developed. We make deployment decisions with the goal of optimizing the overall profitability of our portfolio, with these decisions generally made 18 to 24 months in advance. We have operated at a 91.8% occupancy rate in the year ended December 31, 2015, 92.9% in 2014 and 92.4% in 2013, indicating strong consumer interest in our offerings. Adding new capacity will allow us to expand our inventory of existing itineraries and expand into new markets and destinations. The following table presents summary information concerning the ships we currently operate and their geographic areas of operation based on 2016 itineraries:

The following table presents summary information concerning the two new passenger cruise vessels being constructed with delivery expected in the second quarter of 2017 and the second quarter of 2018, respectively, as well as theVia Australis that we expect to take possession of in the second quarter of 2016, renovate and deploy as a replacement of theNational Geographic Endeavour in the fourth quarter of 2016.

*TheVia Australis is flagged by its current owner in Chile. Registration and flagging in Ecuador will take place upon completion of the acquisition and the vessel is put in service.

Owned Vessels

National Geographic Explorer, our flagship vessel, joined the fleet in 2008 as our ultimate expedition ship. TheExploreris equipped with an ice-strengthened hull, advanced navigation equipment for polar expeditions and a well-appointed interior with numerous windows for viewing nature. Accordingly, theExplorer is equipped to visit some of the most remote and extreme areas on the planet. TheExplorer accommodates 148 guests in 81 cabins, including 13 cabins with private balconies and six suites. TheExplorer is spacious and modern, with a variety of public areas that offer views of the passing landscape, including a window-lined library and observation lounge located at the top of the ship, several observation decks and a forward-facing chart room.

National Geographic Orion was designed and built in Germany in 2003 and was substantially enhanced in 2013 upon joining our fleet. TheOrion is designed to be self-sufficient for expedition travel with operations focused in Antarctica, Europe and the Arctic. Engineered with comfort and safety in mind, theOrion is a blue water, ice class vessel equipped with advanced technology, including large retractable stabilizers, sonar, radar and an ice-strengthened hull. A shallow draft as well as bow and stern thrusters allow for maneuvering close to shore. TheOrionaccommodates 102 guests in 53 cabins, including several with balconies and a variety of public spaces that offer panoramic views of the passing landscape. The public rooms include a window-lined main lounge, as well as an observation lounge and library at the top of the ship, with numerous observation decks.

National Geographic Endeavour operates year-round in the Galápagos. Prior to its post to warm equatorial waters, theEndeavourvoyaged from pole-to-pole with extensive periods in the icy waters of the Arctic and Antarctic. TheEndeavour accommodates 95 guests in 56 outside cabins, including two suites, and offers comfortable public areas and extensive open deck space. TheVia Australisis expected to join the fleet in the second quarter of 2016 and, following a significant renovation, is expected to be deployed during the fourth quarter of 2016. TheVia Australis will replace theNational Geographic Endeavour and will operate in the Galápagos. TheVia Australisaccommodates 95 guests in 50 cabins and offers public areas designed for maximum viewing with quick, easy access to decks to respond to bridge announcements of phenomenal sightings of nature and wildlife.

National Geographic Islander is a twin-hulled, yacht-scale ship designed for active exploration. TheIslanderwas originally built for service in the Caribbean, and then later used for expeditions in the Scottish Highlands. Since 2004, theIslander has been sailing year-round in the Galápagos, which it is ideally suited for as its trim design and maneuvering abilities enable it to visit areas larger vessels cannot, allowing guests to experience the islands from a more up-close perspective. TheIslanderaccommodates 47 guests in 24 outside cabins, including two suites. On board there are open decks that are complete with hammocks as well as a large dining room and large lounges that form part of the social hub of the ship.

National Geographic Sea Bird is the twin ship of theSea Lion and offers expedition cruises in Alaska, the Pacific Northwest, Baja California and the Sea of Cortez. TheSea Bird has a shallow draft and small size and can reach places inaccessible to larger ships. TheSea Bird accommodates 62 guests in 31 outside cabins.

National Geographic Sea Lion is the twin ship of theSea Bird and operates in Alaska, the Pacific Northwest, Baja California, the Sea of Cortez, Costa Rica, and Panama. TheSea Lion has a shallow draft and a small size so that it can reach places inaccessible to larger ships. TheSea Lion accommodates 62 guests in 31 outside cabins and has an open bow that provides for shared wildlife viewing experiences.

Chartered Vessels

Delfin II is a riverboat recently built to explore the Peruvian Amazon.Delfin II accommodates 28 guests in 10 suites and four master suites. The entire third deck is open-air, offering a view of the river and the rainforest. Furnishings are made of harvested local rain forest wood and the ship is decorated with handicrafts from the ribereños, native people of the wildlife preserves.

TheSea Cloud has extensive public spaces on the top deck, a dining room that can accommodate all guests at once for single seating and a lounge.

Ship Maintenance

In addition to routine repairs and maintenance performed on an ongoing basis and in accordance with applicable requirements, each of our expedition ships is taken out of service for a scheduled deeper maintenance period to conduct repairs and improvements. We maintain our fleet in accordance with applicable regulations, international conventions and insurance requirements. This includes regularly scheduled maintenance, periodic inspections, drydocking, wetdocking, and overhaul. In addition, renovations and replacements of various vessel elements are part of the ongoing process of maintaining the vessels to a high standard. On a year-to-year basis, increases in maintenance expense for the current owned fleet are anticipated to grow in line with inflation. For U.S. flagged ships, the statutory requirement is an annual docking and U.S. Coast Guard inspections, normally conducted in drydock. Internationally flagged ships have scheduled dockings approximately every 12 months, for a period of up to three to six weeks. Drydock interval and required inspections are statutory requirements controlled under chapters of the International Convention of the Safety of Life at Seas (“SOLAS”) and Classification Society instructions. Under these regulations, passenger ships must be inspected in drydock twice in five years, with the maximum duration between each drydock inspection not to exceed three years, and an underwater hull inspection is required annually. To the extent practical, each ship’s crew, catering and hotel staff remain with the ship during docking periods and assist in performing repair and maintenance work. We do not earn revenue while ships are in dock. Accordingly, dockings are typically planned during non-peak demand periods to minimize the adverse effect on revenue that results from ships being out of service.

Guest Activities and Services

We provide our guests the opportunity and the tools to be active and engaged explorers.

Vessels include a variety of equipment for exploration which, depending on the ship and destination, may include Zodiacs for water-level activities and quick transfers to shore, kayaks for personal exploration, motorized skiffs, an underwater camera, a remotely operated vehicle capable of reaching depths of 1,000 feet, a video microscope to study some of the smallest organisms of the marine ecosystem, a crow’s nest camera atop a ship’s mast, hydrophones for listening to vocalizations of marine mammals, snorkeling gear, scuba gear, and wetsuits. An experienced and knowledgeable expedition staff leads guests in exploration while hiking onshore, paddling on the water or observing wildlife from onboard the ship. All voyages feature a certified photo instructor onboard and many include photographers from National Geographic.

Our ships allow guests to be close to wild nature, but at the same time, enjoy a high level of comfort and convenience. High quality dining is an integral part of our expedition experience with influences and flavors that reflect the regions being explored, along with traditional fare. All food prepared aboard is sourced locally whenever practicable from sustainable providers. Seating is open and the atmosphere is relaxed. Our ships offer a range of services and amenities which allow our guests to travel in comfort. Depending on the ship, these may include a fitness center, a spa offering a variety of treatments, a photo kiosk for photographers to edit and sort photos, a pool, 24-hour beverage service, internet connection, laundry facilities, and a doctor on call.

We offer to handle virtually all travel aspects related to guest reservations and transportation, simplifying the planning and booking process for our guests. We also provide guests the opportunity to purchase pre- and post-expedition extensions or services that may include additional hotel nights, air travel, private transfers, excursions, land travel packages, and travel protection insurance.

Operations

Sales and Marketing

We place a strong emphasis on identifying the needs of our guests and creating expedition opportunities and products that guests value. We use communication strategies and marketing campaigns designed to strengthen brand awareness and to emphasize the distinctive qualities of each expedition we offer. Marketing strategies include the use of direct mail, traditional media, social media, brand websites and travel agencies.

We source our business through a combination of direct selling, travel agency networks and our strategic alliance with National Geographic. We believe in the value of the travel agency network distribution channel and invest in maintaining strong relationships with our key travel agency network partners and seek to maintain commission rates and incentive structures that are competitive within the marketplace.

Historically, our focus has been to primarily source guests for our expeditions from the U.S.United States. Expedition cruise guests sourced from the U.S. represented approximately 87%90%, 84%89% and 92%85% of our total global expedition cruise guestsguests’ ticket revenue in 2015, 20142017, 2016 and 2013, respectively. Guest ticket revenues generated by sales originating in countries outside of the U.S. were approximately 15%, 19% and 8% of total tour revenues in 2015, 2014 and 2013, respectively.

Our largest channel for guest bookings is direct contact, either by guests calling our toll-free number(1-800-EXPEDITION) and speaking with our expedition specialists, or requesting a reservation online at our website, expeditions.com. The direct channel represented nearly 43%41%, 49%39% and 46%43% of guest ticket revenues for 2017, 2016 and 2015, 2014 and 2013, respectively.

Our second largest channel isWe also generate significant bookings from travel agents and wholesalers, representing approximately 28%, 28%27% for the year ended 2017 and 26% of guest ticket revenues27% for 2015, 2014the years ended 2016 and 2013, respectively.2015. Agent outreach efforts are focused primarily on consortiums, or travel agent networks, which target affluent travelers. The four consortiums with which we have preferred partner agreements are Virtuoso, Signature, American Express and Ensemble. Preferred status provides their agents with financial incentives to book their customers on our expeditions and provides us the opportunity for enhanced marketing to their agents and end-user customers. Our agent and affinity sales team meet with hundreds of highly-targeted agents annually, at consortium conferences and training seminars, and in-person at agency offices to provide hands-on training, support and product knowledge. In addition, a very select group of highly-productive and motivated agents can earn incremental commissions as part of theLEX Leaders incentive program.

The National Geographic relationship also serves as a channel for bookings. Our alliance with National Geographic includes a co-selling and co-marketing arrangement through which National Geographic promotes our offerings in its marketing campaigns across web-based, email, print and other marketing platforms and sells our expeditions through its internal travel division. The National Geographic channel represented approximately 24%25%, 20%27% and 22%24% of guest ticket revenues for 2017, 2016 and 2015, 2014 and 2013, respectively.

The remainder of our bookings, 5%6%, 3%7% and 6%5% of guest ticket revenues for 2015, 20142017, 2016 and 2013,2015, respectively, comes from affinity groups and charters. Affinity groups are predominantly college and university alumni associations, and other travel organizations targeting specific market niches.

We have a broad and diverse marketing mix across multiple media platforms and channels, allowing us to effectively communicate our product offerings to past guests and prospective guests. We continually optimize our media mix to reach our target demographic. The majority of our annual global marketing spend is focused on consumer-direct channels, with direct mail being the largest segment of our marketing expenditures. Our detailed brochures present our expedition offerings comprehensively, providing guests with all the information needed to make an informed travel decision. We also execute direct mail campaigns with the primary purpose of generating qualified leads, upon which we will fulfill requests with the appropriate product brochure and/or DVD.digital media. We also promote our expeditions across a variety of print media, primarily magazines targeting affluent travelers, as well as nature and photography enthusiasts.

Our website, expeditions.com,www.expeditions.com, is supported internally by a dynamic content management system, allowing frequent updates, a visually-impactful design, large photos and video display with simple, straightforward navigation. We also send weekly mobile-optimized emails to our database of opt-in email subscribers, which link back to key areas on expeditions.com. In addition, we routinely offer webinars to offer greater insights into our expeditions, hosted by members of the expedition teams with intimate knowledge of the geographies featured.

We maintain an active presence on numerous social media platforms, focusing primarily on those with the greatest reach to our target demographic: Facebook, Instagram, Twitter, and YouTube.demographic. In addition, we routinely feed content to National Geographic’s social media platforms, which extend the reach of our brand significantly.

Our marketing and sales team is based in the U.S. and Sydney, Australia. The marketing team encompasses broad and diverse skill sets including product and channel marketing, digital marketing, database marketing, copywriting and creative, video production and research and analytics.

Expedition Cruise Pricing

Our voyage prices typically include accommodations and all expedition activities and meals, other than items of a personal nature, such as alcohol, airfare to and from an expedition, spa treatments and certain other specialized events or activities. Prices vary depending on many factors, including the destination,vessel, the destinations on a particular voyage, number of guest berths available, expedition length, cabin category selected and time of year during which the expedition takes place. Payment terms generally require an upfront deposit to confirm a reservation with the balance due prior to departure.

We focus on maintaining list pricing of our offerings and any discounting that we pursue is tactical, targeted and infrequent. In addition to our standard expedition packages, we may be able to offer a complete vessel for charter and may provide incentives for this type of arrangement. Group and multi-generational family travel may also be eligible for additional incentives based upon the voyage, duration and number of guests travelling. From time to time, we may incentivize guests to book with us with a variety of offers, including free or reduced price air transportation, hotel nights or other value addedvalue-added items. We offer rewards to our guests through our loyalty program,Friends for Life, to encourage repeat business.

Lindblad Expeditions – National Geographic Joint Fund for Exploration and Conservation

We seek to inspire people to explore and care about the planet. One of our governing principles is to positively impact the areas we explore and in which we work. To this end, we, along with the National Geographic Society, created the LEX-NG Fund to support projects at the global, regional and local level. The objective of the LEX-NG Fund is to protect the last wild places in the ocean, support innovative local projects and facilitate conservation, research, educational,education and community development projects in the places we explore. Together with our guests, we have raised more than $11.0$9 million since 1997, along with the Fund was established in 2008. In addition, 500,000 shares in Capitolof Lindblad common stock were contributed, or committed to be contributed, to the LEX-NG Fund by the founders of Capitol Acquisition Corp. II in connection with the merger with Lindblad Expeditions, Inc., to support the regions that we visit. Since we and the National Geographic Society together cover the LEX-NG Fund’s operating costs, 100% of guest contributions go directly to on-the-ground projects. In 2017, eight key regions plus two major National Geographic conservation and education initiatives were supported with an aggregate amount of $1.5 million. The majority of funds were donated by guests traveling aboard our fleet. The LEX-NG Fund is managed jointly by one of our staff members and two National Geographic Society staff members, and the Board is currently comprised of five members, including Sven-Olof Lindblad, our founder, President and Chief Executive Officer, and Dr. Jonathan Baillie, Chief Scientist and Senior Vice President, Science & Exploration at the National Geographic Society.

We currently operate a fleet of seven owned expedition ships and five seasonal charter vessels under the Lindblad brand. We have a longstanding relationship with the National Geographic Society, which was founded on a shared interest in exploration, research, technology and conservation. This relationship includes co-selling, co-marketing and branding arrangements with National Geographic Partners, LLC (“National Geographic”) whereby our owned vessels carry the National Geographic name and National Geographic sells our expeditions through its internal travel divisions. We collaborate with National Geographic on expedition planning to enhance the guest experience by having National Geographic experts, including photographers, writers, marine biologists, naturalists, field researchers and film crews, join our expeditions. Guests have the ability to interface with these experts through lectures, excursions, dining and other experiences throughout their expedition.

Environmental Stewardship

Our staff is involved in organizations such as the International Association of Antarctic Tour Operators and the Association of Arctic Expedition Cruise Operators, which seek to lead the tourism industry with management best practices for visiting places such as Antarctica, the Arctic and the Galápagos Islands. Our staff also works with the MarViva Foundation (a non-governmental organization focused on promoting the conservation and sustainable use of coastal and marine ecosystems in the eastern tropical Pacific) to provide a consumer market for sustainably caught fish from the first designated responsible fishing area of Costa Rica. We also work with the Charles Darwin Research Station and Charles Darwin Foundation on conservation initiatives geared toward preserving the Galápagos Islands.

Seasonality

We chooseOur tour revenues from the sale of guest tickets are mildly seasonal, historically larger in the first and third quarters. The seasonality of our operating results fluctuates due to visit geographic areasour vessels being taken out of service for scheduled maintenance or drydocking, which is typically during nonpeak demand periods, in the second and fourth quarters. Our drydock schedules are subject to cost and timing differences from year to year due to the availability of shipyards for certain work, drydock locations based upon many factors, including weather, marineon ship itineraries, operating conditions migration patterns, and various natural phenomena. Inexperienced especially in the northern hemisphere summer months, we visit the High Arcticpolar regions of the world, the Canadian Maritimes, Europe, and Alaska. In the northern hemisphere winter months, we travel to Antarctica, South America, Costa Rica, Baja California, and the Caribbean. The Galápagos Islands areapplicable regulations of class societies in the maritime industry, which require more extensive reviews periodically. Drydocking impacts operating results by reducing tour revenues and increasing cost of tours. Natural Habitat is a year-round destination offering a diverse varietyseasonal business, with the majority of marine, landits tour revenue recorded in the third and airborne wildlife.fourth quarter from its summer season departures and polar bear tours.

Suppliers

Our largest capital expenditures are for ship maintenance and acquisition and ourmaintenance. Our largest operating expenditures are for payroll, fuel, food and beverage, travel agent services and advertising and marketing. Most of the supplies that we require are available from numerous sources at competitive prices.

Insurance

We maintain comprehensive insurance coverage at commercially reasonable rates and believe that our current coverage is at appropriate levels to protect against most of the risk involved in the conduct of our business.

We maintain insurance on the hull and machinery of each of our ships that includes additional coverage for disbursements, earnings and increased value. We also maintain protection and indemnity insurance for each of our owned ships. In addition, we maintain war risk insurance on each ship, which covers damage due to acts of war, including invasion, insurrection, terrorism, rebellion, piracy and hijacking. This coverage includes coverage for physical damage to the ship, which is not covered under the hull policies, as a result of war exclusion clauses in such hull policies. We also maintain protection and indemnity war risk coverage. Consistent with most marine war risk policies, under the terms of the war risk insurance coverage, underwriters can give notice that the policy will be canceled and reinstated at higher premium rates. We also maintain insurance coverage for shoreside property, shipboard inventory and marine and non-marine general liability risks, as well as business interruption insurance for our owned ships based on the evaluation of the financial exposure per vessel for net income and fixed overhead expenses.profitability. In addition, we maintain workers compensation, directorsdirectors’ and officers’ liability and other insurance coverage.

We historically have been able to obtain insurance coverage in amounts and at premiums we have deemed to be commercially acceptable. No assurance can be given that affordable and secure insurance markets will be available in the future, particularly for war risk insurance. All of our insurance coverage is subject to certain limitations, exclusions and deductible levels.

Regulation

Our ships are regulated by various international, national, state and local laws, regulations and treaties in force in the jurisdictions in which they operate. In addition, certain ships are registered in the U.S., the Bahamas or Ecuador, as applicable. Each ship is subject to regulations issued by its country of registry, including regulations issued pursuant to international treaties governing the safety of the ships, guests and crew as well as environmental protection. Each country of registry conducts periodic inspections to verify compliance with these regulations. Ships operating out of U.S. ports are subject to inspection by the U.S. Coast Guard for compliance with international treaties and by the United States Public Health Service for sanitary and health conditions. Ships are also subject to similar inspections pursuant to the laws and regulations of various other countries visited. We consider ourselves to be in material compliance with all the regulations applicable to our ships and that we have all licenses necessary to conduct our business. Health, safety, security, environmental and financial responsibility issues are, and will continue to be, an area of focus by the relevant government authorities in the U.S. and internationally. From time to time, various regulatory and legislative changes may be proposed that could impact operations and subject us to increasing compliance costs in the future.

Safety and Security Regulations

Our ships are required to comply with international safety standards defined in the International Convention for Safety of Life at Sea (“SOLAS”), which, among other things, establishes requirements for ship design, structural features, materials, construction, life-saving equipment and safe management, and operation of ships to ensure guest and crew safety. The SOLAS standards are revised from time to time and the most recent modifications were phased in through 2010. SOLAS incorporates the International Safety Management Code (“ISM Code”), which provides an international standard for the safe management and operation of ships and for pollution prevention. The ISM Code is mandatory for all vessels, including passenger vessel operators. All of our operations and ships are regularly audited by various national authorities and maintain the required certificates of compliance with the ISM Code.

TheOur ships are also subject to various security requirements, including the International Ship and Port Facility Security Code (“ISPS Code”), which is part of SOLAS, and the U.S. Maritime Transportation Security Act of 2002 (“MTSA”), which applies to ships that operate in U.S. ports. In order to satisfy these security requirements, we implement security measures, conduct vessel security assessments and develop security plans. The security plans for all of the ships have been submitted to, and approved by, the respective countries of registry for compliance with the ISPS Code and the MTSA.

The Cruise Vessel Security and Safety Act of 2010, which applies to passenger vessels that embark passengers from or include port stops within the U.S., requires the implementation of certain safety design features as well the establishment of practices for the reporting of and dealing with allegations of crime.

Environmental Regulations

We are subject to various U.S. and international laws and regulations relating to environmental protection. Under such laws and regulations, we are prohibited from, among other things, discharging certain materials, such as petrochemicals and plastics, into the waterways. From time to time, environmental and other regulators may consider more stringent regulations, which may affect our operations and increase compliance costs.

The ships are subject to the International Maritime Organization’s regulations under the International Convention for the Prevention of Pollution from Ships (the ‘‘MARPOL Regulations’’“MARPOL Regulations”), which includes requirements designed to minimize pollution by oil, sewage, garbage and air emissions. We have obtained the relevant international compliance certificates relating to oil, sewage and air pollution prevention for all of our ships.

The MARPOL Regulations impose global limitations on the sulfur content of fuel used by ships operating worldwide and also establish special Emission Control Areas (‘‘ECAs’’(“ECAs”) with stringent limitations on sulfur and nitrogen oxide emissions in these areas. As of February 2014, there were four established ECAs: the Baltic Sea, the North Sea/English Channel, certain of the waters surrounding the North American coast, and the waters surrounding Puerto Rico and the U.S. Virgin Islands. Since July 1, 2010,Currently, ships operating in ECAs are required to operate on fuel with a sulfur content of 1.0%not more than 0.1% m/m (mass by mass). Ships operating elsewhere are subject to a limit of 3.5%, which wasis expected to be reduced to 0.1% effective January 1, 2015. Bynot more than 0.5% m/m on and after January 1, 2020 (or January 1, 2025 if the MARPOL Regulations will requireInternational Maritime Organization elects to defer the worldwide limitations onnew cap of sulfur content following a review of the availability of low sulfur fuel to be further reduced to 0.5%for use by ships).

In July 2011, new MARPOL Regulations introduced mandatory measures to reduce greenhouse gas emissions. These include the utilization of an energy efficiency design index (“EEDI”) for new ships as well as the establishment of an energy efficient management plan for all ships. The EEDI is a performance-based mechanism that requires a certain minimum energy efficiency in new ships. These regulations apply to new vessels commissioned after January 1, 2013. In June 2013, the European Commission proposed legislation which would require cruise ship operators using ports in the European Union to monitor and report on the vessels’ annual carbon dioxide emissions starting in 2018.

The Jones Act

As U.S. flag vessels, theNational Geographic Sea Bird, theNational Geographic Sea Lionand theNational Geographic Sea BirdQuest, are subject to the U.S. laws relating to the transport of passengers andor cargo between U.S. ports in the U.S. coastwise trade. Our two newbuild coastal vesselsvessel, theNational Geographic Venture, currently under construction, will also be U.S. flagged.

These laws relating to vessels are principally contained in 46 U.S.C. Chapter 551 and 46 U.S.C. §50501 and the federal regulations promulgated thereunder and are commonly referred to collectively as the “Jones Act.” Subject to limited exceptions, the Jones Act requires, among other things, that vessels engaged in U.S. coastwise trade be owned and operated by “citizens of the United States” within the meaning of the Jones Act. For purposes of the Jones Act, a corporation, for example, must satisfy at least the following requirements to be deemed a U.S. citizen: (i) the corporation must be organized under the laws of the U.S. or of a state, territory or possession thereof; (ii) each of the chief executive officer and the chairman of the board of directors of such corporation, and each person authorized to act in the absence or disability of such persons, must be a U.S. citizen; (iii) no more than a minority of the number of directors of such corporation necessary to constitute a quorum for the transaction of business can be non-U.S. citizens; and (iv) at least 75% of each class or series of stock in such corporation must be beneficially owned by U.S. citizens within the meaning of the Jones Act.

Labor Regulations

The International Labour Organization, an agency of the United Nations that develops worldwide employment standards, adopted a Consolidated Maritime Labour Convention (the “Convention”) in 2006, which became effective in August 2013. The Convention reflects a broad range of standards and conditions governing all aspects of crew management for ships in international commerce, including additional requirements not previously in effect relating to the health, safety, repatriation, entitlements and status of crewmembers and crew recruitment practices. Each of our ships, except for our two ships operating in Ecuador (not a signatory to the Convention), has received its certification of compliance with the requirements of the Convention.

Consumer Financial Responsibility Regulations

U.S. law requires the operators of passenger vessels embarking passengers at U.S. ports to be certified by the United States Federal Maritime Commission as to their ability to satisfy obligations with respect to unearned passenger revenue in case of non-performance, and for liability in case of casualty or personal injury. We satisfy these requirements with respect to our operation of theNational Geographic Sea Bird and,National Geographic Sea Lion andNational Geographic Quest through an escrow account for passenger deposits and through our liability insurers.

Certain jurisdictions require that we establish financial responsibility to our guests resulting from the non-performance of our obligations; however, the related amounts do not have a material effect on our costs.

In Australia and parts of Europe, we are obligated to honor guests’ cruise payments made by them to their travel agents regardless of whether we receive such payments.

Regulations Regarding Protection of Disabled Persons

Our U.S. flag vessels, theNational Geographic Sea Bird, theNational Geographic Sea Lionand theNational Geographic Quest, are subject to the Americans with Disabilities Act (ADA), which creates affirmative requirements intended to facilitate access by disabled persons. The ADA requires that our U.S. flagged vessels make “reasonable accommodation” in their policies, practices and procedures to facilitate the carriage of passengers with disabilities.

In June 2013, the U.S. Architectural and Transportation Barriers Compliance Board proposed guidelines for the construction and alteration of passenger vessels to ensure that the vessels are readily accessible to and usable by passengers with disabilities. If and when finalized, these guidelines will be used by the U.S. Department of Transportation and U.S. Department of Justice to implement mandatory and enforceable standards for passenger vessels covered by the Americans with Disabilities Act. While we believe our vessels have been designed and outfitted to meet the needs of guests with disabilities, weWe cannot, at this time, accurately predict whether we will be required to make material modifications or incur significant additional expenses given the status of the proposed guidelines.

United States Income Taxation

The following is a discussion of the application of the U.S. federal and state income tax laws to us and is based on the current provisions of the United States Internal Revenue Code, Treasury Department regulations, administrative rulings, court decisions and the relevant state tax laws, regulations, rulings and court decisions of the states where we have business operations. All of the foregoing is subject to change, and any such change could affect the accuracy of this discussion.

At the present time, our subsidiaries that are foreign corporations do not derive any significant income from sources within the U.S., and are not subject to significant U.S. federal income taxes. Any income earned by these subsidiaries from sources within the U.S. generally is subject to U.S. federal income tax at a top rate of 35% (and to U.S. branch profits tax at a rate of 30% on effectively connected earnings and profits, subject to certain adjustments) unless the requirements of the exemption under Section 883 of the Internal Revenue Code are met. In general, any U.S. source income earned by one of our subsidiaries that is a foreign corporation qualifies for exemption under Section 883 if this income is derived from or incidental to the international operation of ships, and if the subsidiary is incorporated in a country that grants an equivalent exemption to U.S. corporations. The countries in which our subsidiaries that are foreign corporations are incorporated do grant equivalent exemptions to U.S. corporations. The income of our foreign subsidiaries that is treated as being derived from or incidental to the international operation of ships generally does not include any capital gains recognized upon a disposal of a vessel, or income from the sale of air and land transportation, shore excursions, and pre- and post-cruise tours. If one of our foreign subsidiaries recognizes a capital gain upon a disposal of a vessel, this capital gain will generally constitute income from sources within the U.S. and will generally not be entitled to exemption under Section 883.

Our subsidiaries that are U.S. corporations are subject to U.S. federal income tax at a top rate of 35% on all their income, and are subject to income tax in the various States within the U.S. in which they have operations. At the present time, the only State in which our U.S. subsidiaries are expected to pay significant amounts of state income taxes is Alaska.

We also pay income taxes in Australia, Ecuador and other countries within which we operate. In addition to, or instead of, income taxation, virtually all jurisdictions where our ships call impose some tax or fee, or both, based on guest headcount, tonnage or some other measure.

Competition

We compete with a number of cruise lines with competition varying by destination. The market is fragmented and primarily comprised of private operators. The primary competitors which operate in the geographic regions we serve include Silversea Expeditions, Compagnie du Ponant, Hurtigruten, and Un-Cruise Adventures. We also compete with other vacation alternatives such as land-based resort hotels and sightseeing destinations for guests’ leisure time. Demand for such activities is influenced by political and general economic conditions. Companies within the vacation market are dependent on consumer discretionary spending.

Our principal competitive strengths, particularly our established reputation, experienced management team, product offerings, and association with National Geographic, provide us with a competitive advantage in the specialty cruise segment of the market.

The cruise industry in general and the expedition cruise industry specifically are characterized by high barriers to entry, including the existence of several established and recognizable brands, the large investment required to build a new, sophisticated cruise or expedition ship, the long lead time necessary to construct new ships, and limited newbuild shipyard capacity.

Employees

As of December 31, 2015,2017, we had approximately 368528 employees, including 231312 shipboard employees, 134213 full-time employees and three part-time employees in our shoreside operations.

We arewere originally incorporated in Delaware on August 9, 2010 with the name Capitol Acquisition Corp. II as a specialty cruise operator with operations inblank check company to acquire, through a merger, share exchange, asset acquisition, stock purchase, plan of arrangement, recapitalization, reorganization or other similar business combination, one segment. We evaluate the performance of our business based largely on the results of our single operating segment. We provide discrete financial information in total, by ship and type of ship. The chief operating decision maker, or CODM, and management review operating results monthly, and base operating decisions on the total results. Our reports provided to the Board of Directors are at a consolidated level. Management performance and related compensation is based on total results. Based on this assessment, we concluded that we have one single operating segment and therefore one reportable segment.more businesses or entities.

Risks Related to Our Business and Operations

Adverse worldwide economic, geopolitical or other conditions could reduce the demand for expedition cruisestravel and adversely impact our operating results, cash flows and financial condition, including potentially impairing the value of our fleet, goodwill and other assets.condition.

The demand for travel experiences, including expedition cruises and land-based travel, may be adversely affected by international, national and local economic and geopolitical conditions. In particular, challenginga deterioration in global economic conditions that adversely affectaffects discretionary income and consumer confidence may, in turn, result in expedition booking slowdowns, decreased expeditionbookings, prices and lower onboard revenues for the expedition and cruise and expedition cruise industries as compared to more robust economic times. In addition, any significant deterioration of global economic conditions could result in a prolonged period of booking slowdowns, depressed expedition prices and reduced onboard revenues.industries. Demand for our expedition cruisesexpeditions may also be influenced by geopolitical events. Unfavorable conditions, such as cross-border conflicts, civil unrest and governmental changes, can underminedecrease consumer demand and/orand result in reduced pricing for expeditions in areas affected by such conditions.

We may not be able to obtain sufficient financing or capital for our needs or may not be able to do so on terms that are acceptable or consistent with our expectations.

To fund our capital expenditures and scheduled debt payments, we have historically relied on a combination of cash flows provided by operations, drawdowns under available credit facilities, the incurrence of additional indebtedness and the sale of equity securities in private securities markets. Any circumstance or event which leads to a decrease in consumer cruise spending, such as worsening global economic conditions or significant incidents impacting the cruise industry, the expedition cruise industry, or the travel industry, could negatively affect our operating cash flows.

Although we believe that we have sufficient cash flows from operations and will have sufficient access to capital to fund our operations and obligations as expected, there can be no assurances to that effect. Our ability to access additional funding as and when needed, our ability to timely refinance and/or replace outstanding debt and credit facilities on acceptable terms and our cost of funding will depend upon numerous factors including but not limited to the condition of the financial markets, our financial performance and credit ratings and the performance of our industry in general.

Any inability to satisfy any covenants required by existing or future credit facilities could adversely impact our liquidity.

On July 8, 2015, we entered into the Amended Credit Agreement with Credit Suisse A.G. as Administrative Agent and Collateral Agent. The Amended Credit Agreement (i) requires us to maintain a total net leverage ratio of 4.75 to 1.00 initially, which ratio is reduced by 0.25 on March 31, 2016 with equal reductions annually thereafter until March 31, 2020, when the total net leverage ratio shall be 3.50 to 1.00 thereafter; (ii) limits the amount of indebtedness we may incur generally and specifically for intercompany debt, debt incurred to finance acquisitions and improvements, for capital and synthetic lease obligations, for standby letters of credit, and in connection with refinancings; (iii) limits the amount we may spend in connection with certain types of investments; and (iv) requires the delivery of certain periodic financial statements and an operating budget. The Amended Credit Agreement is secured by substantially all of our assets.

Any failure to comply with such terms, conditions, and covenants could result in an event of default. Further, if an event of default under a credit facility were to occur, cross default provisions, if any, could cause our other outstanding debt, if any, to be immediately due and payable. Upon such an occurrence, there could be no assurance that we would have sufficient liquidity to repay or the ability to refinance the borrowings under any such credit facilities or settle other outstanding contracts if such amounts were accelerated upon an event of default.

Incidents or adverse publicity concerning the cruise vacation industry, the expedition cruisetravel industry or the travel industry in general, weather conditions and other natural disasters or disruptions could affect our reputation as well as impact our sales and results of operations.

The operation and/or use of cruise ships, airplanes, land tours, port facilities and shore excursions involves the risk of accidents, illnesses, mechanical failures, environmental incidents including oil spills, and other incidents. Such incidents which may bring intocause guests and potential guests to question their safety, health, security and vacation satisfaction, whichand could negatively impact our reputation. Incidents involving cruise ships, and, in particularparticularly the safety and security of guests and crew, media coverage thereof, as well as adverse media publicity in general concerning the cruise vacation industry, have impacted and could in the future impact demand for our expedition cruisesexpeditions and pricing in the industry. The considerable expansion in the use of social media over recent years has compounded the potential scope of the negative publicity that could be generated by those incidents. If any such incident occurs during a time of high seasonal demand, the effect could disproportionately impact our results of operations for the year. In addition, incidents involving cruise ships may result in additional costs to our business, including costs related to increasing government or other regulatory oversight and, in the case of incidentsoversight. Incidents involving our own fleet potentialmay result in litigation.

Our fleet and the port facilities we use may also be adversely impacted by weather patterns or natural disasters or disruptions, such as hurricanes, earthquakes and changes in ice flows. It is possible thatfloes. From time to time, we couldmay be forced to alter itineraries or cancel an expedition or a series of expeditions due to these or other factors, which would have an adverse effect oncould negatively impact our sales and profitability. Increases in the frequency, severity or duration of severe weather events, including those related to climate change, could exacerbate the impact and cause further disruption to our operations. In addition, these and any other events whichthat impact the travel industry more generally may negatively impact our ability to deliver guests or crew to our expeditions and/or interrupt our ability to obtain services and goods from key vendors in our supply chain. Any of the foregoing could have an adverse impact on our results of operations and on industry performance.

Ship construction, repair or revitalization delays or mechanical faultsissues on existing vessels may result in cancellation of expeditions or unscheduled drydockings and repairs and thus adversely affect our results of operations.

We depend on shipyards to construct, repair, maintain and revitalize our ships on a timely basis and to ensure they remain in good working order. The sophisticated nature of building, repairing and revitalizing a ship involves risks.risks, and shipyards may encounter financial, technical or design problems when doing these jobs. Delays in ship construction, repair or revitalization or mechanical faultsfailures have in the past and may in the future result in delays or cancellationcancellations of expeditions or necessitateand unscheduled drydocks and repairs of ships. If there is a significant accident, mechanical failure or similar problem involving a ship, we may have to place a ship in drydock for an extended period for repairs. Any such delays, cancellations of expeditions and/or unscheduled drydockings interruptions or disruptions in service of any of our vessels resulting from weather conditions, natural disasters or otherwise could result, could have a severe impactmaterial adverse effect on our business, results of operations and financial condition. These events and any related adverse publicity could result in lost revenue, increased operating expenses, or both, and thus adversely affect our results of operations.

Delays or cost overruns in building new vessels (including the failure to deliver new vessels) could harm us.

Building new vessels is subject to risks of delay (including the failure to timely deliver new vessels to customers) or cost overruns caused by conditions beyond our control, including one or more of the following:

Significant delays, cost overruns and failure to timely deliver new vessels we have committed to service one or more of our customersguests could adversely affect us in several ways, including delaying the implementation of our business strategies, or materially increasing our cost of servicing our commitments to our customers.guests or resulting in the cancellation of scheduled expeditions. In addition, there are a limited number of shipyards with the capability and capacity to build our new ships and, accordingly, increased demand for available new construction slots could impact our ability to construct new ships when and as planned and/or result in stronger bargaining power on the part of the shipyards.

We must make substantial capital expenditures to maintain and/or expand our fleet.

We must make substantial capital expenditures to maintain our fleet in good working order. Maintenance capital expenditures include capital expendituresthose associated with drydocking a vessel, modifying an existing vessel or acquiring a new vessel. These expenditures could increase as a result of changes in the cost of labor and materials; customer requirements; increases in our fleet size or the cost of replacement vessels; governmental regulations and maritime self-regulatory organization standards relating to safety, security or the environment; and competitive standards. In addition, maintenance capital expenditures will vary from quarter to quarter based on the number of vessels drydocked during that quarter. Significant unexpected maintenance capital expenditures could have an adverse impact on our operations.

We will be required to makeare currently making substantial capital expenditures to increase the size of our fleet. We intend to expand our fleet by acquiringconstructing new vessels and may acquire existing vessels from other parties or constructing new vessels. Wein the future. Shipyards generally will be requiredrequire us to make installment payments on any new shipbuildship build prior to their delivery, in the future. Accordingly, we may be requiredwhich requires us to expend a significant amount of money to acquire or build a new vessel without any corresponding revenue for delivery well inan extended period of time. In addition, we may not receive the future.expected demand for our newly constructed or acquired vessels, which could have an adverse impact on our operations

An increase in capacity worldwide or excess capacity in a particular market could adversely impact our expedition sales and/or pricing.

Expedition sales and/or pricing may be impacted both by the introduction of new ships into the marketplace and by deployment decisions of us and our competitors. The further growth in capacity from these new ships and future orders, without an increase in the cruise industry’s share of the vacation market, could depress expedition prices and impede our ability to achieve yield improvement. In addition, to the extent that we or our competitors deploy ships to a particular itinerary and the resulting capacity in that region exceeds the demand, we may consider pricing adjustments, which may result in lower than anticipated profitability. Any of the foregoing could have an adverse impact on our results of operations, cash flows and financial condition including potentially impairing the value of our ships, goodwill and other assets.condition.

If we are unable to appropriately balance our cost management strategies with our goal of satisfying guest expectations, our business may be adversely impacted.

Our goals call for us to provide high quality products and deliver high quality services. There can be no assurances that we can successfully balance these goals with our cost management strategies.

We may lose business to competitors throughout the vacation market.

We operate in the vacation market, and expedition cruising is one of many alternatives for people choosing a vacation. We therefore risk losing business not only to other cruise lines, but also to other vacation operators, which provide other leisure options including hotels, resorts and package holidays and tours.

We face significant competition from other vacation operators and cruise companies on the basis of pricing, destination, travel agent preference and also in terms of the nature of ships and services it offers to guests. Our competition within the expedition and cruise vacation industry depends on the destination and is fragmented and primarily comprised of private operators.

In the event that we do not compete effectively with other vacation operators and cruise companies, our results of operations and financial position could be adversely affected.

Fears of terrorist and pirate attacks, war and other hostilities, travel restrictions and the spread of contagious diseases could have a negative impact on our results of operations.

Events such as terrorist and pirate attacks, war and other hostilities and the resulting political instability, travel restrictions, such as travel bans to and from certain geographical areas and heightened regulations around customs and border control, the spread of contagious diseases, such as the Zika virus, and other related concerns over the safety, health and security aspects of traveling, or the fear of any of the foregoing, have had, and could have in the future, a significant adverse impact on demand and pricing in the travel and vacation industry. In view of our global operations, we are susceptible to a wide range of adverse events.

Fluctuations in foreign currency exchange ratesevents, which could decrease demand and adversely affect our financial results.

We earn revenues, pay expenses, recognize assets and incur liabilities in currencies other than the U.S. dollar, including, among others, the Euro, the Australian Dollar, the Swedish Krona, and the British Pound. In 2014 and 2015, we derived approximately 19% and 15%, respectively, of our guest ticket revenues from operations outside the United States. Because our consolidated financial statements are presented in U.S. dollars, we must convert revenues, income and expenses, as well as assets and liabilities, into U.S. dollars at exchange rates in effect during or at the end of each reporting period. Therefore, absent offsetting changes in other foreign currencies, increases or decreases in the value of the U.S. dollar against other major currencies will affect our revenues, net income and the value of balance sheet items denominated in foreign currencies. We use financial instruments to mitigate our net balance sheet exposure to currency exchange rate fluctuations. However, there can be no assurances that fluctuations in foreign currency exchange rates, particularly the strengthening of the U.S. dollar against major currencies, would not materially affect our financial results.business.

In addition, we have ship maintenance contracts andWe may lose business to competitors throughout the vacation market.

We operate in the future have ship construction contracts which are denominatedvacation market, and expedition cruising is one of many alternatives for people choosing a vacation. We therefore risk losing business not only to other cruise lines, but also to other vacation operators who provide other leisure options, including hotels, resorts and package holidays and tours.

We face significant competition from other vacation operators and cruise companies on the basis of pricing, destination, travel agent preference and also in currencies other than the U.S. Dollar. While we have entered into, and may in the future enter into, forward contracts and collar options to manage a portionterms of the currency risk associated with these contracts,nature of ships and services we are or may be exposedoffer to fluctuations inguests. Our competition within the exchange rates for the portions of the contracts that have not been hedged. Additionally, if a shipyard is unable to perform under such a contract, any foreign currency forward contracts that were entered into to manage the currency risk would need to be terminated. Termination of these contracts could result in a significant loss.

Environmental, labor, healthexpedition and safety, financial responsibility and other maritime regulations could affect operations and increase operating costs.

The United States and various state and foreign government or regulatory agencies have enacted or are considering new environmental regulations or policies, such as requiring the use of low sulfur fuels, increasing fuel efficiency requirements, further restricting emissions, or other initiatives to limit greenhouse gas emissions that could increase our cost for fuel, cause us to incur significant expenses to purchase and/or develop new equipment and adversely impact the cruise vacation industry. Some environmental groups have also lobbied for more stringent regulationindustries depends on the destination and is fragmented and primarily comprised of cruise ships and have generated negative publicity about the cruise vacation industry and its environmental impact. An increase in fuel prices not only impacts our fuel costs, but also some of our other expenses, such as crew travel, freight and commodity prices.private operators.

These issues are, and we believe will continue toposition could be an area of focus by the relevant authorities throughout the world, especially in light of several recent incidents involving cruise ships. This could result in the enactment of more stringent regulation of cruise ships that could subject us to increasing compliance costs in the future.adversely affected.

Conducting business globally may result in increased costs and other risks.

We operate our business globally.globally and plan to continue to expand our international presence. Operating internationally exposes us to a number of risks, including unstable local economic conditions, volatile local political conditions, potential changes in duties and taxes, including changing interpretations of existing tax laws and regulations, potential changes in local laws, rules and regulations, required compliance with additional laws and policies affecting cruising, vacation or maritime businesses or governing the operations of foreign-based companies, currency fluctuations, interest rate movements, government controlled fuel prices, difficulties in operating under local business environments, U.S. and global anti-bribery laws or regulations, imposition of trade barriers, and restrictions on repatriation of earnings. If we are unable to address these risks adequately, our financial position and results of operations could be adversely affected, including potentially impairing the value of our ships, goodwill and other assets.

Operating globally also exposes us to numerous and sometimes conflicting legal and regulatory requirements. In many parts of the world, including countries in which we operate, practices in the local business communities might not conform to international business standards. We must adhere to policies designed to promote legal and regulatory compliance as well as applicable laws and regulations. However, we might not be successful in ensuring that our employees, agents, representatives and other third parties with whom we associate throughout the world properly adhere to them.

Failure by us, our employees or any of these third parties to adhere to our policies or applicable laws or regulations could result in penalties, sanctions, damage to our reputation and related costs which in turn could negatively affect our results of operations and cash flows.

Our attemptsefforts to expand our business into new markets may not be successful.

While our historical focus has been to serve guests from the North American expedition cruise market, we have expandedmay expand our focus to include other global markets. Expansion into new markets requires significant levels of investment. There can be no assurance that any new markets will develop as anticipated or that we will have success in any new markets, and if we do not, we may be unable to recover our investment, which could adversely impact our business, financial condition and results of operations, including potentially impairing the value of our goodwill.

If our redeployment of vessels to a new market with new itineraries is not successful, our business and operating results may be adversely affected.affected.

We cannot predict whether new expeditions and new itineraries offered by any vessels redeployed will attract a number of guests comparable to previous expeditions. If redeployments and new expeditions do not attract as many guests as past expeditions or if there is a delay in finalizing or marketing the new itineraries, our business and operating results may be adversely affected.

Failure to develop the value of our brand and differentiate our products could adversely affect our results of operations.

Our success depends on the strength and continued development of our expedition brand and on the effectiveness of our brand strategies. Failure to protect and differentiate our brand from competitors throughout the vacation market could adversely affect our results of operations.

We have an on-going partnership with National Geographic and the termination or alterations in this relationship may have an adverse effect on our business.

The National Geographic Society is one of the largest non-profit scientific and educational institutions in the world. Its interests include geography, archaeology and natural science, the promotion of environmental and historical conservation, and the study of world culture and history. In furtherance of similar interests and goals, we have entered into a Tour Operator Agreement and an Alliance and License Agreement (collectively, the “NG Agreements”) with National Geographic Partners, LLC.

Pursuant to the NG Agreements, our owned vessels contain the phrase “National Geographic” in their names, we have access to certain of National Geographic’s marks and images for advertising purposes and we and our guests have access to National Geographic photographers, naturalists and other experts. National Geographic may in certain instances terminate the Alliance and License Agreement with us, including upon a termination event caused by a change of control in which Sven-Olof Lindblad or his designated successor ceases to hold a senior management role with the company, a termination due to our failure to achieve specified year-over-year revenue growth percentage requirements, a failure to meet the conditions necessary to extend the relationship through 2025 or otherwise. If the NG Agreements are terminated or modified in any material respect, due to any of the reasons set forth above or otherwise, our results of operations may be materially adversely affected.

We have a relationship with World Wildlife Fund (“WWF”) through our Natural Habitat subsidiary and the termination or alterations in this relationship may have an adverse effect on our Natural Habitat business.

WWF is a leading conservation organization whose mission is to conserve nature and reduce the most pressing threats to the diversity of life on Earth. Natural Habitat partners with WWF to offer conservation travel through a license agreement that allows Natural Habitat to use the WWF name and logo in return for a royalty fee, through 2023.

If Natural Habitat’s license agreement with World Wildlife Fund was terminated or modified in any material respect, our results of operations for the Natural Habitat segment may be materially adversely affected.

We may not be able to obtain sufficient financing or capital for our needs or may not be able to do so on terms that are acceptable or consistent with our expectations.

Any circumstance or event that leads to a decrease in consumer cruise and land-based travel spending, such as worsening global economic conditions or significant incidents impacting the cruise industry, the expedition cruise industry or the travel industry, could negatively affect our operating cash flows. Although we believe that we have sufficient cash flows from operations and will have sufficient access to capital to fund our operations and obligations as expected, there can be no assurances to that effect. Our ability to access additional funding as and when needed, our ability to timely refinance and/or replace outstanding debt and credit facilities on acceptable terms and our cost of funding will depend upon numerous factors including but not limited to the condition of the financial markets, our financial performance and credit ratings and the performance of our industry in general.

Any inability to satisfy any covenants required by existing or future credit facilities could adversely impact our liquidity.

Our Restated Credit Agreement contains certain financial covenants and is secured by substantially all of our assets. Any failure to comply with such terms, conditions, and covenants could result in an event of default. Further, if an event of default under a credit facility were to occur, cross default provisions, if any, could cause our other outstanding debt, if any, to be immediately due and payable. Upon such an occurrence, there could be no assurance that we would have sufficient liquidity to repay or the ability to refinance the borrowings under any such credit facilities or settle other outstanding contracts if such amounts were accelerated upon an event of default.

Environmental, labor, health and safety, financial responsibility and other maritime regulations could affect operations and increase operating costs.

The United States and various state and foreign government or regulatory agencies have enacted or are considering new environmental regulations or policies, such as requiring the use of low sulfur fuels, increasing fuel efficiency requirements, further restricting emissions, or other initiatives to limit greenhouse gas emissions that could increase our cost for fuel, cause us to incur significant expenses to purchase and/or develop new equipment and adversely impact the cruise vacation industry. Some environmental groups, in particular, have also lobbied for more stringent regulation of cruise ships and have generated negative publicity about the cruise vacation industry and its environmental impact. An increase in fuel prices not only impacts our fuel costs, but also some of our other expenses, such as crew travel, freight, air travel, and commodity prices.

In addition, we are subject to various international, national, state and local laws, regulations and treaties that govern, among other things, safety standards applicable to our ships, treatment of disabled persons, health and sanitary standards applicable to our guests, security standards on board our ships and at the ship/port interface areas, and financial responsibilities to our guests. These issues are, and we believe will continue to be, an area of focus by the relevant authorities throughout the world, especially in light of several recent incidents involving cruise ships. This could result in the enactment of more stringent regulation of cruise ships that could subject us to increasing compliance costs in the future.

Our operating costs, especiallyparticularly fuel expenditures, could increase due to market forces and economic or geopolitical factors beyond our control.

Expenditures for fuel represent a significant cost of operating our business. If fuel prices rise significantly in a short period of time, we may be unable to increase fares or other fees sufficiently to offset fully our increased fuel costs. In addition, volatility in fuel prices or disruptions in fuel supplies could have a material adverse effect on our results of operations, financial condition and liquidity. To date, we have not hedged our fuel costs with any fuel derivative instruments. If we decide to enter into such instruments in the future, we will be subject to the risk that the fuel derivatives will not provide adequate protection against significant increases in fuel prices and could in fact result in hedging losses and result in us effectively paying higher than market prices for fuel.

Our other capital expenditure and operating costs, including food, hotel, payroll, maintenance and repair, airfare, taxes, insurance and security costs, are subject to increases due to market forces and economic or political conditions or other factors beyond our control. Increases in these capital expenditure and operating costs could adversely affect our profitability.

Price increases for commercial airline service for our guests or major changes or reductions in commercial airline service and/or availability could increase our operating expenses and adversely impact the demand for cruises and undermine our ability to provide reasonably priced vacation packages to our guests.expedition travel.

Most of our guests depend on scheduled commercial airline services to transport them to or from the ports where our expeditions embark or disembark passengers. Increases in the price of airfare would increase the overall price of the expedition vacation to our guests, which may adversely impact demand for our expeditions. In addition, changes in the availability of commercial airline services could adversely affect our guests’ ability to obtain airfare,air transport, which could adversely affect our results of operations.

Our reliance on travel agencies to sell and market our cruises exposes us to certain risks that, if realized, could adversely impact our business.

Because we rely on travel agencies to generate a substantial portion of the bookings for our ships, we must ensure that our commission rates and incentive structures remain competitive. If we fail to offer competitive compensation packages, these agencies may be incentivized to sell vacation packages offered by our competitors to our detriment, which could adversely impact our operating results. In addition, the travel agent industry is sensitive to economic conditions that impact discretionary income. Significant disruptions or contractions in the industry could reduce the number of travel agencies available for us to market and sell our expeditions, which could have an adverse impact on our financial condition and results of operations.

Disruptions in our shoreside operations or our information systems may adversely affect our results of operations.

Our principal executive office isoffices are located in New York, New York, and our principal shoreside operations are located in Seattle, Washington, and we have a sales office in Australia.Washington. Actual or threatened natural disasters (e.g., hurricanes, earthquakes, tornadoes, fires, and floods), terrorist attacks, or other similar disruptive events in these locations may have a material impact on our business continuity, reputation and results of operations. In addition, substantial or repeated information systems failures, computer viruses or cyber-attacks impacting our shoreside or shipboard operations could adversely impact our business. We do not generally carry business interruption insurance for our shoreside operations or our information systems. As such, any losses or damages incurred by us could have an adverse impact on our results of operations.

Failure to developFluctuations in foreign currency exchange rates could affect our financial results.

We earn revenues, pay expenses, recognize assets and incur liabilities in currencies other than the U.S. dollar, including, among others, the Euro, the Canadian Dollar, the Australian Dollar, the Swedish Krona, and the British Pound. In 2017, 2016 and 2015, we derived approximately 10%, 11% and 15%, respectively, of our guest ticket revenues from guests outside the United States. Because our consolidated financial statements are presented in U.S. dollars, we must convert revenues, income and expenses, as well as assets and liabilities, into U.S. dollars at exchange rates in effect during or at the end of each reporting period. Therefore, absent offsetting changes in other foreign currencies, increases or decreases in the value of our brand and differentiate our products could adverselythe U.S. dollar against other major currencies will affect our resultsrevenues, net income and the value of operations.balance sheet items denominated in foreign currencies. We use limited financial instruments to mitigate our net balance sheet exposure to currency exchange rate fluctuations. However, there can be no assurances that fluctuations in foreign currency exchange rates, particularly the strengthening of the U.S. dollar against major currencies, would not materially affect our financial results.

Our success depends on

In addition, we have ship maintenance contracts and may in the strengthfuture have ship construction contracts which are denominated in currencies other than the U.S. dollar. We may in the future enter into forward contracts and continued development of our expedition brand and on the effectiveness of our brand strategies. Failurecollar options to protect and differentiate our brand from competitors throughout the vacation market could adversely affect our results of operations. We havemanage a co-branding strategy with National Geographic, which is memorialized through an Alliance and License Agreement. Failure to maintain our relationship with National Geographic as a result of a breachportion of the Alliancecurrency risk associated with these contracts, and License Agreement,we are or may be exposed to fluctuations in the exchange rates for the portions of the contracts that have not been hedged. Additionally, if a termination event caused byshipyard is unable to perform under such a changecontract, any foreign currency forward contracts that were entered into to manage the currency risk would need to be terminated. Termination of controlthese contracts could result in which Sven-Olof Lindblad or his designated successor ceases to hold a senior management role with the company, a failure to meet the conditions necessary to extend the relationship through 2025, or otherwise could adversely affect our results of operations.significant loss.

We have an on-going relationship with National Geographic. Termination or alterations in this relationship may have an adverse effect on our business.

National Geographic is one of the largest non-profit scientific and educational institutions in the world. Its interests include geography, archaeology and natural science, the promotion of environmental and historical conservation, and the study of world culture and history. In furtherance of similar interests and goals, we have entered into a Tour Operator Agreement and an Alliance and License Agreement (collectively, the “Agreements”) with National Geographic.

Pursuant to the Agreements, our owned vessels contain the phrase “National Geographic” in their names, we have access to certain of National Geographic’s marks and images for advertising purposes and we and our guests have access to National Geographic photographers, naturalists and other experts. If the Agreements with National Geographic are terminated or the terms of the Agreements are modified in any material respect, our results of operations may be adversely affected.

The loss of key personnel, our inability to recruit or retain qualified personnel, or disruptions among our shipboard personnel due to strained employee relations could adversely affect our results of operations.

Our success depends, in large part, on the reputation, skills and contributions of key executives (including Sven-Olof Lindblad, in particular) and other employees, and on our ability to recruit and retain high quality personnel. Our management team is comprised of individuals with a diverse knowledge base and skill sets acquired through extensive experience in expedition cruising, adventure travel, and hospitality. We must continue to sufficiently recruit, retain, train and motivate our employees to maintain our current business and support our projected growth. A loss of key executives or other key employees or disruptions among our personnel could adversely affect our results of operations.

We rely on third-party providers of various services integral to the operation of our businesses. These third parties may act in ways that could harm our business.

In order to achieve cost and operational efficiencies, we outsource to third-party vendors certain services that are integral to the operations of our global businesses, such as our onboard concessionaires, certain of our call center operations and operation of a large part of our information technology systems.businesses. We are subject to the risk that certain decisions are subject to the control of third-party service providers and that these decisions may adversely affect our activities. A failure to adequately monitor a third-party service provider’s compliance with a service level agreement or regulatory or legal requirements could result in significant economic and reputational harm to us.

There is also a risk that the confidentiality, privacy and/or security of data held by third parties or communicated over third-party networks or platforms could become compromised. Such a breach could adversely affect our reputation and in turn adversely affect our business.

A failure to keep pace with developments in technology or technological obsolescence could impair our operations or competitive position.

Our business continues to demand the use of sophisticated technology and systems, such as reservations and reporting systems. These technologies and systems must be refined, updated and/or replaced with more advanced systems in order to continue to meet our guests’ demands and expectations. If we are unable to do so in a timely manner or within reasonable cost parameters or if we are unable to appropriately and timely train our employees to operate any of these new systems, our business could suffer. We also may not achieve the benefits that we anticipate from any new technology or system, and a failure to do so could result in higher than anticipated costs or could impair our operating results.

We may be exposed to risks and costs associated with protecting the integrity and security of our guests’ and employees’ personal information.

We are subject to various risks associated with the collection, handling, storage and transmission of sensitive information, including risks related to compliance with applicable laws and other contractual obligations, as well as the risk that our systems collecting such information could be compromised. In the course of doing business, we collect large volumes of internal and guest data, including personally identifiable information for various business purposes. If we fail to maintain compliance with the various applicable data collection and privacy laws or with credit card industry standards or other applicable data security standards, we could be exposed to fines, penalties, restrictions, litigation or other expenses, and our business could be adversely impacted. In addition, even if we are fully compliant with legal standards and contractual requirements, we still may not be able to prevent security breaches involving sensitive data. Any breach, theft, loss, or fraudulent use of guest, employee or company data could cause consumers to lose confidence in the security of our information technology systems and choose not to purchase from us and expose us to risks of data loss, business disruption, litigation and other liability, any of which could adversely affect our business.

A change in our tax status under the United States Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”), or other jurisdictions, may have adverse effects on our income.

At the present time, many of our subsidiaries that are foreign corporations do not derive any significant income from sources within the United States, and are not subject to significant United States federal income taxes. Any income earned by these subsidiaries from sources within the United States generally is subject to United States federal income tax (and United States branch profits tax) unless the requirements of the exemption under Section 883 of the Internal Revenue Code are met. Although we expect that any United States source income of our foreign subsidiaries will generally qualify for the benefits of the Section 883 exemption, there is no assurance that such benefits will be available.

If budgetary constraints adversely impactIn addition, the jurisdictionsenactment of legislation implementing changes in which we operate, such as Australia or Ecuador, increases in income tax regulations ortaxation of international business activities, the adoption of other corporate tax reform affectingpolicies, or changes in tax legislation or policies could materially affect our financial position and results of operations. In general, changes in tax laws may affect our tax rate, increase our tax liabilities, carrying value of deferred tax assets, or our deferred tax liabilities. Any substantial changes in international corporate tax policies, enforcement activities or legislative initiatives may materially and adversely affect our business, the amount of taxes we are required to pay and our financial condition and results of operations generally.

Restrictions on travel or access to certain protected or preserved areas could adversely affect our business.

We believe that our expedition itineraries are a major reason why guests choose our expedition cruises over competing cruises and vacation options. However, our ability to follow our planned itinerary for any expedition cruise may be imposed.affected by a number of factors, including security concerns, adverse weather conditions and natural disasters, local government regulations and restrictions and other restrictions on access, including access to protected or preserved areas.

For instance, the number of visitors admitted to the Galápagos National Park at any given time is limited by the number of “cupos” permits issued by the Galápagos National Parks Service. In June 2015, a new Ecuadorian Special Law for Protected Areas was approved and updated in November 2015. A Presidential Decree issued by President Correa of Ecuador in November 2015 established that cupos in effect as of July 2015 will have a validity of nine years. Our rights to operate in the Galapagos will therefore expire in July 2024 and based on the new law and decree, we will begin the renewal process in 2020.

Although the current holders of cupos will have the opportunity to re-apply for them, other enterprises and individuals will also have the opportunity to bid on cupos as they become subject to renewal. All bidders in this process must present proof that they fulfill the conditions to properly utilize the license. Notable criteria include, without limitation, access to a vessel, experience in tourism, a proven record of environmentally sensitive behavior, marketing requirements, etc. If the Galápagos National Parks Service were to further restrict access to the park, we might be required to alter certain of our travel itineraries. Such a development would negatively impact our business and revenues.

Changes in other governmental and environmental rules and regulations in the Galápagos Islands and other travel destinations could also cause sudden losses in revenue, together with additional expenditures due to the need to revise our existing itineraries. Restrictions on access for us and our guests to other protected or preserved areas, including national parks, may result in losses in revenues typically generated by our expeditions to such areas.

Litigation, enforcement actions, fines or penalties could adversely impact our financial condition or results of operations and/or damage our reputation.

Our business is subject to various United States and international laws and regulations that could lead to enforcement actions, fines, civil or criminal penalties or the assertion of litigation claims and damages. In addition, improper conduct by our employees, agents, partners, or expedition representatives could damage our reputation and/or lead to litigation or legal proceedings that could result in civil or criminal penalties, including substantial monetary fines. In certain circumstances, it may not be economical to defend against such matters and/or a legal strategy may not ultimately result in us prevailing in a matter. Such events could lead to an adverse impact on our financial condition or results of operations.

In addition, as a result of any ship-related or other incidents, litigation claims, enforcement actions and regulatory actions and investigations, including, but not limited to, those arising from personal injury, loss of life, loss of or damage to personal property, business interruption losses or environmental damage to any affected coastal waters and the surrounding area, may be asserted or brought against various parties, including us and/or our subsidiaries. The time and attention of our management may also be diverted in defending such claims, actions and investigations. Subject to applicable insurance coverage, we may also incur costs both in defending against any claims, actions and investigations and for any judgments, fines, civil or criminal penalties if such claims, actions or investigations are adversely determined.

Failure to comply with international safety regulations may subject us to increased liability that may adversely affect our insurance coverage resulting in a denial of access to, or detention in, certain ports which could adversely affect our business.

The operation of vessels is affected by the requirements of the International Maritime Organization’s International Safety Management Code for the Safe Operation of Ships and Pollution Prevention (“ISM Code”). The ISM Code requires ship owners and bareboat charterers to develop and maintain an extensive “Safety Management System” that includes the adoption of a safety and environmental protection policy setting forth instructions and procedures for safe operation and describing procedures for dealing with emergencies. Our failure to comply with the ISM Code may subject us to increased liability, invalidate existing insurance or decrease available insurance coverage for the affected vessels and result in a denial of access to or detention in certain ports, all of which could materially and adversely affect our results of operations and liquidity.

Compliance with environmental and other laws and regulations could adversely affect our business.

Extensive and changing environmental protection and other laws and regulations directly affect the operation of our vessels. These laws and regulations take the form of international conventions and agreements, including the International Maritime Organization conventions and regulations and the International Convention for the Safety of Life at Sea, (“SOLAS”), which are applicable to all internationally trading vessels, and national, state and local laws and regulations, all of which are amended frequently. Under these laws and regulations, various governmental and quasi-governmental agencies and other regulatory authorities may require us to obtain permits, licenses and certificates in connection with our operations. Some countries in which we operate have laws that restrict the nationality of a vessel’s crew and prior and future ports of call, as well as other considerations relating to particular national interests. Changes in governmental regulations and safety or other equipment standards may require unbudgeted expenditures for alterations or the addition of new equipment for our vessels.

Restrictions on travel or accessAn inability to certain protected or preserved areasobtain adequate insurance coverage could adversely affect our business.business, financial condition and results of operations.

WeWhile we maintain comprehensive insurance and believe that our expedition itinerariescurrent coverage is at appropriate levels, we are not protected against all risks and there can be no assurance that any particular claim will be fully paid by our insurance. Such losses, to the extent they are not adequately covered by contractual remedies or insurance, could affect our financial results. Our protection and indemnity (“P&I”) liability insurance is placed on a major reason why guests choose our expedition cruises over competing cruisesmutual basis and vacation options. However,we are subject to additional premium calls in amounts based on claim records of all members of the P&I Club. We are also subject to additional premium assessments including, but not limited to, investment or underwriting shortfalls experienced by the P&I Club. If we were to sustain significant losses in the future, our ability to follow our planned itinerary for any particular expedition cruise mayobtain insurance coverage at all or at commercially reasonable rates could be affected by a numbermaterially adversely affected. Moreover, irrespective of factors, including security concerns, adverse weather conditions and natural disasters, local government regulations and restrictions, and other restrictions on accessthe occurrence of such events, there can still be no assurance that we will be able to protectedobtain adequate insurance coverage at commercially reasonable rates or preserved areas.at all.

For instance, the number of visitors admitted to the Galápagos National Park at any given time is limited by the number of cupos permits issued by the Galápagos National Parks Service. In June 2015, a new Ecuadorian Special Law for Protected Areas was approved and updated in November 2015. A Presidential Decree issued by President Correa of Ecuador in November 2015 established that cupos, which were in effect as of July 2015, will have a validity of nine years. Our operating rights are up for renewal in July 2024 and based on the new law, we will begin the renewal process in 2020. The current “owners” of the cupos will have the opportunity to re-apply for them, but any other enterprise or individual will have the opportunity to bid for the cupos. All bidders must present proof that they fulfill the conditions to properly utilize the license (access to a vessel, experience in tourism, proven environmental behavior, marketing, etc.). If the Galápagos National Parks Service were to further restrict access to the park, we might be required to alter certain of our travel itineraries, which would negatively impact our business and revenues.

Further, changes in other governmental and environmental rules and regulations in the Galápagos Islands and elsewhere could cause sudden losses in revenue and additional expenditures for alterations in our itineraries. In addition, restrictions on access by us and our guests to other protected or preserved areas, including national parks, may result in losses in revenues typically generated by our expeditions to such areas.

If we do not restrict the amount of ownership of our common stock by non-U.S. citizens, we could be prohibited from operating vessels in U.S. coastwise trade, which would adversely impact our business and operating results.

To the extent any of our United States flagged vessels are engaged in U.S. coastwise trade, we will be subject to the Jones Act, which governs, among other things, the ownership and operation of passenger vessels used to carry cargo andor passengers between U.S. ports. Subject to limited exceptions, the Jones Act requires that such vessels engaged in the U.S. coastwise trade be built in the United States, registered under the U.S. flag, manned by predominantly U.S. crews, and beneficially owned and operated by U.S. organized companies that are controlled and at least 75% owned by U.S. citizens within the meaning of the Jones Act. A failure to maintain compliance with the Jones Act would adversely affect our financial position and our results of operations andas we would be prohibited from operating vessels in the U.S. coastwise trade during any period in which we do not comply or cannot demonstrate to the satisfaction of the relevant governmental authorities our compliance with the Jones Act. In addition, a failure to maintain compliance could subject us to fines and our vessels could be subject to seizure and forfeiture for violations of the Jones Act and the related U.S. vessel documentation laws.

Restrictions on non-U.S. citizen ownership of certain U.S. flagged vessels could limit our ability to sell off a portion of our business or result in the forfeiture of certain of our vessels.

Compliance with the Jones Act requires that non-U.S. citizens within the meaning of the Jones Act beneficially own no more than 24.99% in the entities that directly or indirectly own the vessels that operate in the U.S. coastwise trade. If we were to seek to sell any portion of our business that owns any of these vessels, we would have fewer potential purchasers, because some potential purchasers might be unable or unwilling to satisfy the U.S. citizenship restrictions described above. As a result, the sales price for that portion of the business may not attain the amount that could be obtained in an unregulated market. Furthermore, if at any point we or any of the entities that directly or indirectly own our vessels cease to satisfy the requirements to be a U.S. citizen within the meaning of the Jones Act, we would become ineligible to operate in the U.S. coastwise trade and may become subject to penalties and risk forfeiture of our United States flagged vessels.

Compliance with the Sarbanes-Oxley Act of 2002 will require substantial financial and management resources.

Section 404 of the Sarbanes-Oxley Act of 2002 requires that we evaluate and report on our system of internal controls. If we fail to maintain the adequacy of our internal controls, we could be subject to regulatory scrutiny, civil or criminal penalties and/or stockholder litigation. Any inability to provide reliable financial reports could harm our business. Any failure to implement required new or improved controls, or difficulties encountered in the implementation of adequate controls over our financial processes and reporting in the future, could harm our operating results or cause us to fail to meet our reporting obligations. Inferior internal controls could also cause investors to lose confidence in our reported financial information, which could have a negative effect on the trading price of our securities.

Risks Related to an Investment in Our Securities

Our amended and restated certificate of incorporation limits the beneficial ownership of our common stock by individuals and entities that are not U.S. citizens within the meaning of the Jones Act. These restrictions may affect the liquidity of our common stock and may result in non-U.S. citizens being required to disgorge profits, sell their shares at a loss or relinquish their voting, dividend and distribution rights.

Under the Jones Act, and so long as we operate U.S. flagged vessels in coastwise trade, at least 75% of the outstanding shares of each class or series of our capital stock must be beneficially owned and controlled by U.S. citizens within the meaning of the Jones Act. Certain provisions of our amended and restated certificate of incorporation are intended to facilitate compliance with this requirement and may have an adverse effect on certain holders or proposed transferees of shares of our common stock.

Under the provisions of our amended and restated certificate of incorporation, any transfer, or attempted transfer, of any shares of capital stock will be void if the effect of such transfer, or attempted transfer, would be to cause one or more non-U.S. citizens in the aggregate to own (of record or beneficially) shares of any class or series of our capital stock in excess of 22% of the outstanding shares of such class or series. The liquidity or market value of the shares of common stock may be adversely impacted by such transfer restrictions.

In the event such restrictions voiding transfers would be ineffective for any reason, our amended and restated certificate of incorporation provides that if any transfer would otherwise result in the number of shares of any class or series of capital stock owned (of record or beneficially) by non-U.S. citizens being in excess of 22% of the outstanding shares of such class or series, such transfer will cause such excess shares to be automatically transferred to a trust for the exclusive benefit of one or more charitable beneficiaries that are U.S. citizens. The proposed transferee will have no rights in the shares transferred to the trust, and the trustee, who is a U.S. citizen chosen by us and unaffiliated with us or the proposed transferee, will have all voting, dividend and distribution rights associated with the shares held in the trust. The trustee will sell such excess shares to a U.S. citizen within 20 days of receiving notice from us and distribute to the proposed transferee the lesser of the price that the proposed transferee paid for such shares and the amount received from the sale, and any gain from the sale will be paid to the charitable beneficiary of the trust.

These trust transfer provisions also apply to situations where ownership of a class or series of capital stock by non-U.S. citizens in excess of 22% would be exceeded by a change in the status of a record or beneficial owner thereof from a U.S. citizen to a non-U.S. citizen, in which case such person will receive the lesser of the market price of the shares on the date of such status change and the amount received from the sale. In addition, under our amended and restated certificate of incorporation, if the sale or other disposition of shares of common stock would result in non-U.S. citizens owning (of record or beneficially) in excess of 22% of the outstanding shares of common stock, the excess shares shall be automatically transferred to a trust for disposal by a trustee in accordance with the trust transfer provisions described above. As part of the foregoing trust transfer provisions, the trustee will be deemed to have offered the excess shares in the trust to us at a price per share equal to the lesser of (i) the market price on the date we accept the offer and (ii) the price per share in the purported transfer or original issuance of shares, as described in the preceding paragraph, or the market price per share on the date of the status change, that resulted in the transfer to the trust.

As a result of the above trust transfer provisions, a proposed transferee that is a non-U.S. citizen or a record or beneficial owner whose citizenship status change results in excess shares may not receive any return on its investment in shares it purportedly purchases or owns, as the case may be, and it may sustain a loss.

To the extent that the above trust transfer provisions would be ineffective for any reason, our amended and restated certificate of incorporation provides that, if the percentage of the shares of any class or series of capital stock owned (of record or beneficially) by non-U.S. citizens is known to us to be in excess of 22% for such class or series, we, in our sole discretion, shall be entitled to redeem all or any portion of such shares most recently acquired (as determined by us in accordance with guidelines that are set forth in our amended and restated certificate of incorporation), by non-U.S. citizens, or owned (of record or beneficially) by non-U.S. citizens as a result of a change in citizenship status, in excess of such permitted percentage for such class or series at a redemption price based on a fair market value formula that is set forth in our amended and restated certificate of incorporation. Such excess shares shall not be accorded any voting, dividend or distribution rights until they have ceased to be excess shares, provided that they have not been already redeemed by us. As a result of these provisions, a stockholdershareholder who is a non-U.S. citizen may be required to sell its shares of common stock at an undesirable time or price and may not receive any return on its investment in such shares. Further, we may have to incur additional indebtedness, or use available cash (if any), to fund all or a portion of such redemption, in which case our financial condition may be materially weakened.

In order to assist our compliance with the Jones Act, our amended and restated certificate of incorporation permits us to require that any record or beneficial owner of any shares of our capital stock provide us with certain documentation concerning such owner’s citizenship. These provisions include a requirement that every person acquiring, directly or indirectly, five percent (5%) or more of the shares of any class or series of our capital stock must provide us with specified citizenship documentation. In the event that any person does not submit such requested or required documentation to us, our amended and restated certificate of incorporation provides us with certain remedies, including the suspension of the voting rights of the person’s shares owned by persons unable or unwilling to submit such documentation and the payment of dividends and distributions with respect to those shares into a segregated account. As a result of non-compliance with these provisions, a record or beneficial owner of the shares of our common stock may lose significant rights associated with those shares.

In addition to the risks described above, the foregoing ownership restrictions on non-U.S. citizens could delay, defer or prevent a transaction or change in control that might involve a premium price for common stock or otherwise be in the best interest of our stockholders.shareholders.

If non-U.S. citizens own more than 22% of our common stock, we may not have the funds or the ability to redeem any excess shares and the charitable trust mechanism described above may be deemed invalid or unenforceable, all with the result that we could be forced to either suspend our operations in the U.S. coastwise trade or be subject to substantial penalties.

Our amended and restated certificate of incorporation contains provisions voiding transfers of shares of any class or series of our capital stock that would result in non-U.S. citizens within the meaning of the Jones Act, in the aggregate, owning in excess of 22% of the shares of such class or series. In the event that this transfer restriction would be ineffective, our amended and restated certificate of incorporation provides for the automatic transfer of such excess shares to a trust specified therein. These trust provisions also apply to excess shares that would result from a change in the status of a record or beneficial owner of shares of our capital stock from a U.S. citizen to a non-U.S. citizen. In the event that these trust transfer provisions would also be ineffective, our amended and restated certificate of incorporation permits us to redeem such excess shares. The per-share redemption price may be paid, as determined by our Board of Directors, by cash or redemption notes or the shares may be redeemed for warrants. However, we may not be able to redeem such excess shares for cash because our operations may not have generated sufficient excess cash flow to fund such redemption. Further, the methodology for transfer to and sale by a charitable trust could be deemed invalid or unenforceable in one or more jurisdictions. If, for any reason, we are unable to effect a redemption or charitable sale when beneficial ownership of shares by non-U.S. citizens is in excess of 24.99% of the common stock, or otherwise prevent non-U.S. citizens in the aggregate from beneficially owning shares in excess of 24.99% of any class or series of capital stock, or fail to exercise our redemption or forced sale rights because we are unaware that ownership exceeds such percentage, we will likely be unable to comply with the Jones Act and will likely be required by the applicable governmental authorities to suspend our operations in the U.S. coastwise trade. Any such actions by governmental authorities would have a severely detrimental impact on our financial position, results of operations and cash flows and any failure to suspend operations in violation of the Jones Act could cause us to be subject to material financial and operational penalties.

If we do not maintain a current and effective prospectus relating to the shares of common stock issuable upon exercise of the warrants, warrant holders will only be able to exercise such warrants on a “cashless basis.”

If we do not maintain a current and effective prospectus relating to the shares of common stock issuable upon exercise of the public warrants at the time that holders wish to exercise such warrants, they will only be able to exercise them on a “cashless basis” pursuant to the exemption provided by Section 3(a)(9) of the Securities Act of 1933, as amended. As a result, the number of shares of common stock that holders will receive upon exercise of the public warrants will be fewer than it would have been had such holder exercised his warrant for cash. Further, if an exemption from registration is not available, holders would not be able to exercise on a cashless basis and would only be able to exercise their warrants for cash if a current and effective prospectus relating to the common stock issuable upon exercise of the warrants is available. Under the terms of the warrant agreement, we have agreed to use our best efforts to meet these conditions and to maintain a current and effective prospectus relating to the shares of common stock issuable upon exercise of the warrants until the expiration of the warrants. However, we cannot assure you that we will be able to do so. If we are unable to do so, the potential “upside” of the holder’s investment in our company may be reduced or the warrants may expire worthless.

An investor will only be able to exercise a warrant if the issuance of shares of common stock upon such exercise has been registered or qualified or is deemed exempt under the securities laws of the state of residence of the holder of the warrants.

No warrants will be exercisable for cash and we will not be obligated to issue shares of common stock unless the shares of common stock issuable upon such exercise has been registered or qualified or deemed to be exempt under the securities laws of the state of residence of the holder of the warrants. If the shares of common stock issuable upon exercise of the warrants are not qualified or exempt from qualification in the jurisdictions in which the holders of the warrants reside, the warrants may be deprived of any value, the market for the warrants may be limited and they may expire worthless if they cannot be sold.

We may amend the terms of the warrants in a way that may be adverse to holders with the approval by the holders of a majority of the then outstanding warrants.

Our warrants are issued in registered form under a warrant agreement between Continental Stock Transfer & Trust Company, as warrant agent, and us. The warrant agreement provides that the terms of the warrants may be amended without the consent of any holder to cure any ambiguity or correct any defective provision. The warrant agreement requires the approval by the holders of a majority of the then outstanding warrants (including the sponsor’s warrants) in order to make any change that adversely affects the interests of the registered holders. Accordingly, we may amend the terms of the warrants in a manner adverse to a holder if the holders of a majority of the warrants approve of such amendment.

We are an “emerging growth company” and we cannot be certain if the reduced disclosure requirements applicable to emerging growth companies will make our shares of common stock less attractive to investors.

We are an “emerging growth company,” as defined in the Jumpstart our Business Startups Act of 2012 (“JOBS Act”). We will remain an “emerging growth company” for up to five years.until December 31, 2018. However, if our non-convertible debt issued within a three yearthree-year period or revenues exceeds $1 billion, or the market value of our shares of common stock that are held by non-affiliates exceeds $700 million on the last day of the second fiscal quarter of any given fiscal year, we would cease to be an emerging growth company as of the following fiscal year. As an emerging growth company, we are not required to comply with the auditor attestation requirements of section 404 of the Sarbanes-Oxley Act, we have reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements and we are exempt from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved. Additionally, as an emerging growth company, we have elected to delay the adoption of new or revised accounting standards that have different effective dates for public and private companies until those standards apply to private companies. As such, our financial statements may not be comparable to companies that comply with public company effective dates.Act. We cannot predict if investors will find our shares of common stock less attractive because we may rely on these provisions. If some investors find our shares of common stock less attractive as a result, there may be a less active trading market for our shares and our share price may be more volatile.

Our outstanding warrants may have an adverse effect on the market price of shares of common stock.

As of March7, 2016,February 26, 2018, we had issued and outstanding warrants to purchase 12,040,93710,103,828 shares of common stock. The sale, or even the possibility of sale, of the shares underlying the warrants could have an adverse effect on the market price for our securities or on our ability to obtain future financing. If and to the extent these warrants are exercised, you may experience dilution to your holdings.

We may redeem the warrants at a time that is not beneficial to public investors.

We may call the public warrants for redemption at any time after the redemption criteria described in the prospectus for our initial public offering have been satisfied. If we call the public warrants for redemption, public stockholdersshareholders may be forced to accept a nominal redemption price or sell or exercise the warrants when they may not wish to do so.

Our management’s ability to require holders of our warrants to exercise such warrants on a cashless basis will cause holders to receive fewer shares of common stock upon their exercise of the warrants than they would have received had they been able to exercise their warrants for cash.

If we call our public warrants for redemption after the redemption criteria described in the prospectus for our initial public offering have been satisfied, our management will have the option to require any holder that wishes to exercise its warrant (including any warrants held by our initial stockholdersshareholders or their permitted transferees) to do so on a “cashless basis.” If our management chooses to require holders to exercise their warrants on a cashless basis, the number of shares of common stock received by a holder upon exercise will be fewer than it would have been had such holder exercised his warrant for cash. This will have the effect of reducing the potential “upside” of the holder’s investment in our company.

An active trading market for our common stock may not be sustained, and you may not be able to resell your shares at or above the price at which you purchased them.

An active trading market for our shares may not be sustained. In the absence of an active trading market for our common stock, shares of common stock may not be able to be resold at or above the purchase price of such shares. Although there can be no assurances, we expect that our common stock will continue to be listed on the NASDAQ Stock Market. However, even if our common stock continues to be listed on the NASDAQ Stock Market, there is no assurance that an active market for our common stock will continue in the foreseeable future.

We do not intend to pay any dividends to stockholdersshareholders in the foreseeable future.

We have not paid any cash dividends on our shares of common stock to date and do not intend to pay cash dividends in the foreseeable future. The payment of cash dividends in the future will be dependent upon our revenues and earnings, if any, capital requirements and general financial conditions. The payment of any dividends is within the discretion of our Board of Directors. It is the present intention of our Board of Directors to retain all earnings, if any, for use in our business operations and, accordingly, our Board of Directors does not anticipate declaring any dividends in the foreseeable future. As a result, any gain you will realize on our securities will result solely from the appreciation of such securities.

Provisions in our amended and restated certificate of incorporation and bylaws and Delaware law may inhibit a takeover of us, which could limit the price investors might be willing to pay in the future for our common stock and could entrench management.

Our amended and restated certificate of incorporation and bylaws contain provisions that may discourage unsolicited takeover proposals that stockholders may consider to be in their best interests. Our board of directors is divided into three classes, each of which will generally serve for a term of three years with only one class of directors being elected in each year. As a result, at a given annual meeting only a minority of the board of directors may be considered for election. Since our “staggered board” may prevent our stockholders from replacing a majority of our board of directors at any given annual meeting, it may entrench management and discourage unsolicited stockholder proposals that may be in the best interests of stockholders. Moreover, our Board of Directors has the ability to designate the terms of and issue new series of preferred stock.

We are also subject to anti-takeover provisions under Delaware law, which could delay or prevent a change of control. Together these provisions may make more difficult the removal of management and may discourage transactions that otherwise could involve payment of a premium over prevailing market prices for our securities.

Our mission is offering life-changing adventures on all seven continents and pioneering innovative ways to allow our guests to connect with exotic and remote places. Our

We currently operate a fleet of seven owned expedition ships are customized, nimble and intimately-scaledfive seasonal charter vessels that are able to venture where larger cruise ships cannot, thus allowing us to offer up-close experiences inunder the planet’s wild and remote places and capitals of culture. Many of these expeditions involve travel to remote places with limited infrastructure and ports (such as Antarctica and the Artic) or places that are best accessed byLindblad brand. We have a ship (such as the Galápagos, Alaska, Baja’s Sea of Cortez, Costa Rica, and Panama), and foster active engagement by guests. Each expedition ship is designed to be comfortable and inviting, while being fully equipped with state-of-the-art tools for in-depth exploration. We also have anstrategic business alliance with National Geographic founded on a shared interest in exploration, research, technology and conservation. This relationship includes a co-selling, co-marketing and branding arrangement whereby our owned vessels carry the National Geographic Society (“name and National Geographic”), who often provides lecturers andGeographic sells our expeditions through its internal travel division. We collaborate with National Geographic on voyage planning to enhance the guest experience by having National Geographic experts, including photographers, writers, marine biologists, naturalists, field researchers and film crews.crews, join our expeditions. Guests have the ability to interface with these experts through lectures, excursions, dining and other experiences throughout their voyage.

The key components of our business strategy are to deliver exceptional guest experiences, maximize occupancy levels, continually optimize pricing methodologies, effectively manage itinerary offerings to meet guest demand, maximize and grow net yields, elevate brand awareness and loyalty, and expand and operate the business in a safe, prudent and disciplined manner.

A perspective on how we maximize occupancy and optimize pricing is illustrated in the redeployment of theNational Geographic Orion, which came under our management in 2013. We added departures from the Antarctic Peninsula and extensive travel across the Pacific Ocean as well as began marketing the vessel’s offerings in the U.S., a core marketing region where we command strong pricing. In 2016, we further repositioned theNational Geographic Orion by redeploying the ship from serving the Western Australian geographies to voyages in Europe for the northern hemisphere summer. We deploy chartered vessels for various seasonal offerings and continually seek to optimize our charter fleet to balance our inventory with demand and maximized yields. We use our charter inventory as a mechanism to both increase travel options of our existing and prospective guests and also to test demand for certain areas and seasons to understand the potential for longer term deployments and additional vessel needs.

We continually evaluate a range of strategies for expansion of guest capacity. We consider closely the expected return on invested capital and the range of possibilities, such as a newbuild program, adding selected charters and the acquisition of existing ships or small operators. In December 2015, we executed definitive agreements for the construction of two new coastal vessels for delivery targeted in the second quarter of 2017 and the second quarter of 2018 at a purchase price of $48.0 million and $46.8 million, respectively. These 236-foot vessels are expected to have capacity of approximately 100 guests each and management considers this investment to be an important step to meet increasing demand for our offerings. The newbuild process will expose us to certain risks typically associated with new ship construction, which we are prepared to manage through detailed planning and close monitoring by our internal marine team. The purchase of the ships will be funded through a combination of cash available on our balance sheet and excess cash flows generated by our existing operations. Also in December 2015, we signed a definitive agreement for the purchase of theVia Australis to be used in our operations in the Galápagos Islands. We expect to take possession of the ship in the second quarter of 2016 and following a significant renovation expect to deploy the ship during the fourth quarter of 2016. TheVia Australis will replace theNational Geographic Endeavour. The purchase price for the ship is $18.0 million and we plan to spend up to $10.0 million to refurbish and outfit the ship immediately after closing.

We maintain our fleet in accordance with applicable regulations, international conventions and insurance requirements. This includes regularly scheduled maintenance, periodic inspections, drydocking, and overhaul. In addition, renovations and replacements of various vessel elements are part of the ongoing process of maintaining the vessels to a high standard. Following the acquisition of theNational Geographic Orion, the vessel underwent an extensive drydock process during which we added our own specific modifications in order for the ship to meet its operational requirements. On a year-to-year basis, increases in maintenance expense for the current owned fleet are anticipated to grow in line with inflation.

Due to the specific geographies in which we operate and the cost of providing access to fuel in our remote destinations, we have historically not experienced significant fluctuations in fuel costs with changes in world fuel commodity prices. However, the continued downward pressure is now becoming evident on fuel prices in all areas of the world in which we operate. Fuel costs represented 4.3%3.2%, 5.9%3.4% and 6.4%4.3% of our Lindblad segment tour revenues for the years ended December 31, 2017, 2016 and 2015, 2014respectively.

In November 2017, the Company executed a contract to build a polar ice class vessel targeted to be competed in January 2020, with potential accelerated delivery to November 2019, with a total purchase price of 1,066.0 million Norwegian Kroner (NOK). Subsequently, LME exercised its right to make payments in United States Dollars, which resulted in a purchase price of $134.6 million, including hedging costs. The first twenty percent of the purchase price was paid shortly after execution of the Agreement with the remaining eighty percent due upon delivery and 2013, respectively. We have not hedgedacceptance of the vessel. The polar ice class contract includes options to build two additional ice class vessels, the first for delivery twelve months after the initial vessel and the second for delivery twelve months thereafter. The new build process exposes us to certain risks typically associated with new ship construction, which we manage through detailed planning and close monitoring by our fuel purchases historically, but we are evaluating a hedging strategy to manage cash flows related to variable interest and fuel prices.internal marine team.

SimilarIn December 2015, we entered into two separate contracts with Ice Floe LLC, to othersbuild theNational Geographic Quest and theNational Geographic Venture. Management considers this investment to be an important step to meet increasing demand for our expedition cruise offerings. TheNational Geographic Quest launched in the industry,third quarter of 2017 and operated in Alaska and British Columbia during the summer of 2017 before voyaging to Costa Rica and Panama to provide expeditions for the Northern Hemisphere winter season.

In December 2016, we have historically operated withlaunched theNational Geographic Endeavour II,which replaced theNational Geographic Endeavour.Endeavour II will operate year-round in the Galápagos Islands.National Geographic Endeavourwas fully depreciated and we incurred a meaningful working capital deficit. This deficit is mainly attributable to the fact that, under our business model, a vast majority of guest ticket receipts are collected in advance$0.8 million loss on disposal of the applicable sailing date. These advance passenger receipts remain a current liability untilvessel during the sailing datefourth quarter of 2016.

In the fourth quarter of 2016, theNational Geographic Orion experienced an issue with its main engine and the cash generated from them is used interchangeably with cash on hand from other cash from operations. However, as a result we cancelled one voyage in 2016 and four voyages during the first quarter of 2017 for necessary engine repairs and in the first quarter of 2017, theNational Geographic Sea Lion cancelled two voyages to repair the onboard air conditioning system. In addition, the delayed delivery of the AmendedNational Geographic Questcaused the cancellation of four highly booked voyages. The Company estimates that the impact of these cancellations was approximately $12.4 million in tour revenues and $9.0 million Adjusted EBITDA in 2017.

 On May 4, 2016, we expanded our land-based offerings by acquiring an 80.1% ownership interest in Natural Habitat, Inc. (“Natural Habitat”), an adventure travel and ecotourism company based in Colorado. Natural Habitat was founded by Benjamin L. Bressler, who retains a 19.9% noncontrolling interest in Natural Habitat. Examples of Natural Habitat’s expeditions include African safaris in Botswana, grizzly bear adventures in Alaska and polar bear tours in Canada. Since 2003, Natural Habitat has partnered with the World Wildlife Fund (“WWF”) to offer conservation travel, sustainable travel that directly protects nature. This agreement with WWF extends through 2023.

 On March 7, 2016, we entered into a Restated Credit Agreement with Credit Suisse, amending our existing senior secured credit facility with Credit Suisse (“Restated Credit Facility”). The Restated Credit Facility provides for our Company’s existing $175.0 million senior secured first lien term loan facility and a new $45.0 million senior secured incremental revolving credit facility (“Revolving Credit Facility”), which includes a $5.0 million letter of credit sub facility. Our obligations under the merger proceeds, we had net working capitalRestated Credit Facility are secured by substantially all our assets. See Note 7 – Long-Term Debt in the Notes to the consolidated financial statements in Item 8 of $130.0 million as of December 31, 2015 as compared to a working capital deficit of $59.7 million as of December 31, 2014.this Annual Report on Form 10-K for additional information regarding the Restated Credit Agreement.

The discussion and analysis of our financial condition and results of operations isand financial condition are organized as follows:

Critical Accounting Policies and Estimates

Our consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”), which require us to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the financial statements, the reported amounts of revenues and expenses during the reporting periods and the related disclosures in the consolidated financial statements and accompanying footnotes. Out of our significant accounting policies, which are described in Note 2 –Summary of Significant Accounting Policies of our consolidated financial statements included elsewhere in this Form 10-K, certain accounting policies are deemed “critical,” as they require management’s highest degree of judgment, estimates and assumptions. While management believes its judgments, estimates and assumptions are reasonable, they are based on information presently available and actual results may differ significantly from those estimates under different assumptions and conditions.

Stock-Based Compensation

We estimate the fair value of share-based payment awards on the date of the grant using an option-pricing model and restricted share values and recognize the expense over the required service periods.

For recording our stock-based compensation expense for service-based options, we have chosen to use:

The three factors which most affect stock-based compensation are the fair value of the common stock underlying the stock options, the vesting term of the options and the volatility of such fair value of the underlying common stock. If our estimates are too high or too low, we may overstate or understate our stock-based compensation expense.Financial Presentation

Income Taxes

To measure deferred tax assets and liabilities, we provide a valuation allowance against deferred tax assets if, based upon the weight of available evidence, we do not believe it is “more-likely-than-not” that some or all of the deferred tax assets will be realized. We will continue to evaluate the deferred tax asset valuation allowance balances in all of our foreign and U.S. companies to determine the appropriate level of valuation allowances. While we believe that the amount of the recorded financial statement benefits and tax reserves reflect the more-likely-than-not criteria, it is possible that the ultimate outcome of current or future examinations may result in a reduction to the tax benefits previously recorded on our consolidated financial statements or may exceed the current income tax reserves in amounts that could be material.

Valuation of Long-Lived Assets

We review our long-lived assets, principally our vessels and operating rights, for impairment whenever events or changes in circumstances indicate that the carrying amounts of these assets may not be fully recoverable. Upon the occurrence of a triggering event, the assessment of possible impairment is based on our ability to recover the carrying value of our asset, which is determined by using the asset’s estimated undiscounted future cash flows. If these estimated undiscounted future cash flows are less than the carrying value of the asset, an impairment charge is recognized for the excess, if any, of the asset’s carrying value over its estimated fair value. A significant amount of judgment is required in estimating the future cash flows and fair values of our vessels and operating rights.

As of December 31, 2015 and 2014, there was no triggering event and we did not record an impairment of our long-lived assets. We reviewed the remaining useful life of theNational Geographic Endeavour, which is expected to be replaced by theVia Australis in the fourth quarter of 2016. The evaluation of theNational Geographic Endeavour’s useful life as of December 31, 2015 indicated a shorter remaining useful life of less than one year versus the previous estimated remaining useful life of seven years (see Note 5 – Property and Equipment). We do not expect any residual value for theNational Geographic Endeavour after the end of the fourth quarter of 2016. We also evaluated a new law in Ecuador and its effect on our operating rights in the Galápagos Islands. As a result of the new law, the life of the cupos changed from indefinite lives to nine years and amortization of operating rights began in August 2015 (see Note 4 – Operating Rights).

Financial Presentation

Description of Certain Line Items

Tour revenues

Tour revenues consist of the following:

Cost of tours

Cost of tours includes the following:

Selling and marketing

Selling and marketing expenses include commissions and a broad range of advertising and promotional expenses.

General and administrative

General and administrative expenses primarily include the cost of shoreside vessel support, reservations and other administrative functions, including salaries and related benefits, credit card commissions, professional fees and rent.

Key Operational and Financial Metrics

We use a variety of operational and financial metrics, which are defined below, to evaluate our performance and financial condition. We use certainincluding non-GAAP financial measures, such as EBITDA, Adjusted EBITDA, Net Yields and Net Cruise Costs, to enable us to analyze our performance and financial condition. We utilize these financial measures to manage our business on a day-to-day basis and believe that they are the most relevant measures of performance. Some of these measures are commonly used in the cruise and tourism industry to measureevaluate performance. We believe these non-GAAP measures provide expanded insight to measureassess revenue and cost performance, in addition to the standard GAAP-based financial measures. There are no specific rules or regulations for determining non-GAAP measures, and as such, they may not be comparable to measures used by other companies within the industry.

The presentation of non-GAAP financial information should not be considered in isolation or as a substitute for, or superior to, the financial information prepared and presented in accordance with GAAP. You should read this discussion and analysis of our financial condition and results of operations and financial condition together with the consolidated financial statements and the related notes thereto also included within.in Item 8 of this Annual Report on Form 10-K.

Adjusted EBITDAis net income (loss) excluding depreciation and amortization, net interest expense and income tax benefit (expense).

Adjusted EBITDA is net income (loss) excluding depreciation and amortization, net interest expense, other income (expense), income tax (expense) benefit, (expense),(gain) loss on foreign currency, (gain) loss on transfer of assets, reorganization costs, and other supplemental adjustments. Other supplemental adjustments include certain non-operating items such as stock-based compensation, executive severance costs, the National Geographic fee amortization, merger-related expenses and acquisition-related expenses and retention expenses. We believeThe Company believes Adjusted EBITDA, when considered along with other performance measures, is a useful measure as it reflects certain operating drivers of the business, such as sales growth, operating costs, selling and administrative expense, and other operating income and expense. We believeThe Company believes Adjusted EBITDA canhelps provide a more complete understanding of the underlying operating results and trends and an enhanced overall understanding of ourthe Company’s financial performance and prospects for the future. While Adjusted EBITDA is not a recognized measure under GAAP, management uses this financial measure to evaluate and forecast business performance. Adjusted EBITDA is not intended to be a measure of liquidity or cash flows from operations or a measure comparable to net income as it does not take into account certain requirements, such as unearned passenger revenue,revenues, capital expenditures and related depreciation, principal and interest payments, and tax payments. OurThe Company’s use of Adjusted EBITDA may not be comparable to other companies within the industry. Management compensates for these limitations by using Adjusted EBITDA as only one of several measures for evaluating our business performance. In addition, capital expenditures, which impact depreciation and amortization, interest expense, and income tax benefit (expense), are reviewed separately by management.

The following metrics apply to our Lindblad segment:

Adjusted Net Cruise Costrepresents Net Cruise Cost adjusted for Non-GAAP other supplemental adjustments which include certain non-operating items such as stock-based compensation, the National Geographic fee amortization, merger-related expenses, and acquisition-related expenses.

Available Guest Nightsis a measurement of capacity and represents double occupancy per cabin (except single occupancy for a single capacity cabin) multiplied by the number of cruise days for the period. We also record the number of guest nights available on our limited land programs in this definition. We use this measure to perform capacity and rate analysis to identify the main non-capacity drivers that cause revenue and expense to vary.

Gross Cruise Cost represents the sum of cost of tours plus merger-related expenses, selling and marketing expenseexpenses, and general and administrative expense.expenses.

Gross Yieldrepresents tour revenues less insurance proceeds divided by Available Guest Nights.

Guest Nights Soldrepresents the number of guests carried for the period multiplied by the number of nights sailed within the period.

Maximum Guestsis a measure of capacity and represents the maximum number of guests in a period and is based on double occupancy per cabin (except single occupancy for a single capacity cabin).

Net Cruise Costrepresents Gross Cruise Cost excluding commissions and certain other direct costs of guest ticket revenues and other tour revenues.

Net Cruise Cost excludingExcluding Fuelrepresents Net Cruise Cost excluding fuel costs.

Net Revenuerepresents tour revenues less insurance proceeds, commissions and direct costs of other tour revenues.

Net Yieldrepresents Net Revenue divided by Available Guest Nights.

Number of Guestsrepresents the number of guests that travel with us in a period.

Occupancyis calculated by dividing Guest Nights Sold by Available Guest Nights.

Voyagesrepresent the number of ship expeditions completed during the period.

Foreign Currency Translation

We becameSeasonality

Lindblad tour revenues from the sale of guest tickets are mildly seasonal, historically larger in the first and third quarters. The seasonality of our operating results increases due to our vessels being taken out of service for scheduled maintenance or drydocking, which is typically during non-peak demand periods, in the second and fourth quarters. Our drydock schedules are subject to foreign currency translationcost and timing differences from year to year due to the availability of shipyards for certain work, drydock locations based on ship itineraries, operating conditions experienced especially in connectionthe polar regions, and the applicable regulations of class societies in the maritime industry, which require more extensive reviews periodically. Drydocking impacts operating results by reducing tour revenues and increasing cost of tours. Natural Habitat is a seasonal business, with our acquisitionthe majority of Fillmore Pearl Holdings Ltd., which operates partiallyits tour revenue recorded in Australia and whose functional currency is the U.S. dollar.

Results of Operations

Results and demand for our business continued to improve in 2015.

In the year ended December 31, 2015, we generated revenues of $210.0 million compared to revenues of $198.5 million for the year ended December 31, 2014, which represents an increase of $11.5 million, or 5.8%. Net income was $19.7 million and $22.2 million for the years ended December 31, 2015 and 2014, respectively. For the year ended December 31, 2015, we generated Adjusted EBITDA (as defined below) of $46.8 million compared to $44.6 million for the year ended December 31, 2014.fourth quarter from polar bear tours.

Results of Operations – Consolidated

We reported consolidated tour revenues, cost of tours, operating expenses, operating income and net income for the years ended December 31, 2015, 20142017, 2016 and 20132015 as shown in the following table:

Comparison of Years Ended December 31, 2017 and December 31, 2016 - Consolidated

The following table sets forth our operating data as a percentage of total revenue:Tour Revenues

Tour revenues increased $24.2 million, or 10%, to $266.5 million in 2017 compared to $242.3 million in 2016. The Lindblad segment increased tour revenues by $9.0 million driven primarily by the launch of theNational Geographic Quest and theNational Geographic Endeavour II,as well as additional charter expeditions, partially offset by the cancellation of four highly booked voyages on theNational Geographic Orion and two highly booked voyages on theNational Geographic Sea Lion. Tour revenues at the Natural Habitat segment, which was acquired in the second quarter of 2016, increased $15.2 million primarily due to a full twelve months of operations in 2017. It is estimated that total company tour revenues would have increased approximately $36.5 million, or 15%, over the prior year to $278.9 million excluding the impact of the voyage cancellations on theNational Geographic Orion and theNational Geographic Sea Lionand the delayed delivery of theNational Geographic Quest.
