Item 1. Business

Business Overview

TravelCenters of America LLC, which we refer to as the Company or we, us and our, is a Delaware limited liability company. As of December 31, 2017 , we operated and franchised 538 travel centers, standalone convenience stores and standalone restaurants. Our customers include trucking fleets and their drivers, independent truck drivers, highway and local motorists and casual diners. We also collect rents, royalties and other fees from our tenants and franchisees.

We manage our business on the basis of two separately reportable segments, travel centers and convenience stores. See Note 15 to the Notes to Consolidated Financial Statements included in Item 15 of this Annual Report for more information about our reportable segments. We have a single travel center located in a foreign country, Canada, that we do not consider material to our operations.

As of December 31, 2017 , our business included 256 travel centers in 43 states in the United States, primarily along the U.S. interstate highway system, and the province of Ontario, Canada. Our travel centers included 178 locations operated under the "TravelCenters of America" and "TA" brand names and 78 locations operated under the "Petro Stopping Centers" and "Petro" brand names. Of our 256 travel centers at December 31, 2017 , we owned 30 , we leased 200 , we operated two for a joint venture in which we own a noncontrolling interest and 24 were owned or leased from others by our franchisees. We operated 228 of our travel centers and franchisees operated 28 travel centers, including four we leased to franchisees. Our travel centers offer a broad range of products and services, including diesel fuel and gasoline, as well as nonfuel products and services such as truck repair and maintenance services, full service restaurants, quick service restaurants, or QSRs, and various customer amenities. We report this portion of our business as our travel center segment.

As of December 31, 2017 , our business included 233 convenience stores in 11 states in the United States. We operate our convenience stores under the "Minit Mart" brand name. Of these 233 convenience stores at December 31, 2017 , we owned 198 , we leased 32 and we operated three for a joint venture in which we own a noncontrolling interest. Our convenience stores offer gasoline as well as a variety of nonfuel products and services, including coffee, groceries, some fresh foods, and, in many stores, a QSR and/or car wash. We report this portion of our business as our convenience store segment.

As of December 31, 2017 , our business included 49 standalone restaurants in 13 states in the United States operated primarily under the "Quaker Steak & Lube", or QSL, brand name. Of our 49 standalone restaurants at December 31, 2017 , we owned six , we leased nine , we operated one for a joint venture in which we own a noncontrolling interest and 33 were owned or leased from others by our franchisees. We report this portion of our business within corporate and other in our segment information.

As of December 31, 2017 , we employed approximately 14,430 people on a full time basis and 8,533 people on a part time basis at our travel centers, convenience stores and standalone restaurants and we employed an additional 914 people in field management, corporate and other roles to support our locations. Thirty-two of our employees at two travel centers are represented by unions.

Our Growth Strategy

Since 2011, a significant component of our growth strategy has been to acquire and develop additional locations. We currently intend to continue our efforts to selectively acquire and develop properties and businesses and to otherwise grow our business. We believe that in addition to growing our business through our acquisition and development activities, we have opportunities to increase revenues and profits through continued investment in our existing properties and our other business initiatives, such as our TA Truck Service programs further described below. Recent investments and improvements have included projects such as parking lot expansions, restaurant remodeling or rebranding, construction of additional truck repair bays, the installation of additional QSR offerings, installation of car washes, installation of diesel exhaust fluid, or DEF, dispensers, installation of biodiesel blending equipment, and the expansion of our Reserve-It!® parking, RoadSquad®, RoadSquad OnSite® and TA Commercial Tire Network™ offerings.

During the period 2011 through 2017 , we acquired, developed and franchised 46 travel centers, 228 convenience stores and 49 standalone restaurants and have invested an aggregate of $912.0 million to develop, purchase and improve these locations.

Travel centers . Since 2011, we acquired 38 travel centers in a number of acquisition transactions for an aggregate investment of $328.9 million , including costs of renovations. In 2016 we completed construction of three travel centers and in 2017 we completed the construction of an additional travel center. These four new travel centers were developed on land we owned for an aggregate investment of $97.0 million and were subsequently sold to, and leased back from, HPT. In 2011 and 2016 we added three and one new franchised travel centers, respectively, with a new franchisee.

Convenience stores . In 2013, 2015 and 2016, we acquired 31 , 168 and 29 convenience stores, respectively, in a number of acquisition transactions for an aggregate investment of $443.4 million , including costs of renovations.

Standalone restaurants . In 2015 and 2016 we acquired one and 48 standalone restaurants, respectively, 39 of which were owned and operated by franchisees, and in 2017 we acquired six standalone restaurants from one of our franchisees for an aggregate investment of $42.7 million , including costs of renovations.

Typical improvements we make at acquired travel centers include adding truck repair facilities and nationally branded QSRs, paving parking lots, rebranding travel stores to the Minit Mart brand, rebranding gasoline offerings, replacing outdated fuel dispensers, installing DEF dispensing systems, changing signage, installing point of sale and other information technology, or IT, systems and general building and cosmetic upgrades. The cost of capital improvements to recently purchased travel centers and the development of new travel centers are often substantial and require a long period of time to plan, design, permit and complete; and, after being completed, the improved, or new, travel centers require a period of time to become part of our customers' supply networks and produce stabilized financial results. We estimate that the travel centers we acquire generally will reach financial stabilization approximately three years after completion of improvements or development, but actual results can vary widely from this estimate due to many factors, some of which are outside our control, and there can be no assurance that acquired locations will operate profitably.

Typical improvements we make at acquired convenience stores include rebranding to the Minit Mart brand, adding QSRs, rebranding gasoline offerings and correcting deferred maintenance. Improvements to our convenience stores require a period of time to plan, design, permit and complete, often followed by a period of time for integration into our operations. We estimate that the convenience stores that we acquire will generally reach financial stabilization approximately one year after completion of improvements, but the actual results can vary widely from the estimate due to many factors, some of which are outside our control, and there can be no assurance that acquired locations will operate profitably.

See Note 2 to the Notes to Consolidated Financial Statements in Item 15 of this Annual Report for more information about our acquisitions during 2017, 2016 and 2015.

Our Travel Center and Convenience Store Locations

Travel Centers

Our typical travel center includes:

Substantially all of our travel centers are full service sites located on or near an interstate highway exit and offer fuel and nonfuel products and services 24 hours per day, 365 days per year.

Our travel center locations offer a broad range of products and services designed to appeal to our customers, including:

Convenience Stores

Our typical convenience store includes:

The majority of our convenience stores are open 24 hours per day, 365 days per year.

Our convenience store locations offer a broad range of products and services designed to appeal to our customers, including:

TA Truck Service

In addition to the truck repair and maintenance services provided at our travel centers, we also provide customers a wide variety of "off site" repair and maintenance services, as described below.

Operations

Our travel centers and convenience stores offer certain similar products and services, and utilize some of the same suppliers, as discussed further below.

Fuel. We sell fuel to our customers at prices that we establish daily or are indexed to market prices and reset daily. For the year ended December 31, 2017 , diesel fuel and gasoline revenue represented approximately 75% and 25% , respectively, of our total fuel revenue. For the year ended December 31, 2017 , approximately 78% of our diesel fuel was sold at discounts to posted prices under pricing arrangements with customers. We have numerous sources for our diesel fuel and gasoline supply, including nearly all of the large oil companies operating in the United States. We purchase diesel fuel from various suppliers at rates that fluctuate with market prices and generally are reset daily. By establishing diesel fuel supply relationships with several alternate suppliers for most locations, we believe we are able to effectively create competition for our purchases among various diesel fuel suppliers. We also believe that purchasing arrangements with multiple diesel fuel suppliers may help us avoid product outages during times of diesel fuel supply disruptions. At some locations, however, there are few suppliers for diesel fuel in that market and we may have only one viable supplier. Generally we have single sources of supply for gasoline at each of our locations. We offer biodiesel at a number of our travel centers and have a limited number of suppliers for this product at those sites.

A large majority of truck drivers use a payment method known as truck "fuel cards," which allows truck drivers to purchase fuel and other goods and services, and permits trucking companies to track fuel and other purchases made by their drivers throughout the United States. Most of our trucking customers transact business with us by use of fuel cards, most of which are issued by third party fuel card companies. The fuel card industry has only two significant participants, FleetCor Technologies, Inc., the parent of Comdata Inc., or Comdata, and its subsidiaries, or FleetCor, and WEX Inc., and its subsidiaries, or WEX. We believe almost all trucking companies use only a single fuel card provider and have become increasingly dependent upon the data, reports and other services provided by their respective sole fuel card provider to manage their fleets and simplify their data processing.

Generally our fuel purchases are delivered directly from suppliers' terminals to our locations. We generally do not contract to purchase substantial quantities of fuel to hold as inventory. We generally have only a few days of diesel fuel and gasoline inventory at our travel centers and convenience stores. We believe our exposure to market price increases for diesel fuel and gasoline is partially mitigated by the significant amount of our diesel fuel and gasoline sales that are sold under arrangements that include pricing formulae that reset daily and are indexed to market prices and by us generally not purchasing fuel for delivery other than on the date of purchase. We historically have not engaged in any fixed or hedged price fuel contracts.

Nonfuel Products. We have many sources for the large variety of nonfuel products that we sell. We have developed supply relationships with several suppliers of certain nonfuel products, including Daimler for truck parts, Bridgestone Corporation, Continental AG, Cooper Tire and Rubber Company, Goodyear Tire and Rubber Company, Michelin North America, Inc. and Yokohama Tire Corporation for truck tires, McLane Company, Inc. for travel and convenience store and tobacco products, U.S. Foods for restaurant food products and ExxonMobil Oil Corporation and Equilon Enterprises LLC doing business as Shell Oil Products U.S., or Shell, for lubricants. We maintain two distribution centers to distribute certain nonfuel and nonperishable products to our locations using a combination of contract carriers and our fleet of trucks and trailers. We believe these distribution centers allow us to purchase, maintain and transport inventory and supplies at lower costs.

Daimler Agreement . We are party to an agreement with Daimler that extends to July 2019. Daimler is a leading manufacturer of large trucks and truck engines in North America under the Freightliner, Western Star and Detroit Diesel brand names. Except for locations in Texas, our TA and Petro truck repair and maintenance facilities are authorized providers of repair work and specified warranty repairs to Daimler's customers. This is accomplished through the Freightliner ServicePoint® program at TA locations and through the Freightliner and/or Western Star ServicePoint® programs at our Petro locations. Our TA and Petro truck maintenance and repair facilities are also part of Freightliner's 24 hour customer assistance database for emergency and roadside repair referrals and we have access generally to Daimler's parts distribution, service and technical information systems.

Competition

Travel Centers

Fuel and nonfuel products and services can be obtained by trucking companies and truck drivers from a variety of sources, including national and regional full service travel centers and pumper only truck stops, some of which are owned or franchised by large chains and some of which are independently owned and operated, and some large service stations. In addition, some trucking companies operate their own terminals to provide fuel and services to their own trucking fleets and drivers. Some of our competitors may have more resources than we do and vertically integrated fuel and other businesses which may provide them competitive advantages. For all of these reasons and others, we can provide no assurance that we will be able to compete successfully.

We believe that although the travel center and truck stop industry is highly fragmented, with approximately 6,400 travel centers and truck stops in the United States, the largest trucking fleets tend to purchase the majority of their fuel from us and our two largest competitors. We believe that large trucking fleets and long haul trucking fleets tend to purchase the large majority of their fuel at the approximately 1,900 travel centers and truck stops that are located at or near interstate highway exits. Based on the number of locations, TA, Pilot Travel Centers LLC, or Pilot, and Love's Travel Stops and Country Stores, Inc., or Love's, are the three largest companies focused principally on the travel center industry. We believe that, during 2017 , both of our principal competitors, Pilot and Love's, added significantly more travel centers to their networks than we added to our network, and in some cases competition from new sites added by Pilot and Love's has negatively impacted our unit results. Nevertheless, we believe we are able to compete successfully in part because many of our travel centers were originally developed years ago when prime real estate locations along the interstate highway system were more readily available than they are today, which we believe would make it difficult to fully replicate our travel center business, and also in part because of our full service offerings and larger locations that are not often replicated by our principal competitors.

We compete with other travel center and truck stop chains based primarily on diesel fuel prices and the quality, variety and pricing of our nonfuel products, services and amenities. Our truck repair and maintenance facilities compete with other providers of truck repair and maintenance facilities, including some at Pilot and Love's locations. These two competitors have increased their respective numbers of truck repair and maintenance facilities and service offerings over the past few years. For truck maintenance and repair services, we also compete with regional full service travel center and smaller truck stop chains, full service independently owned and operated travel centers and truck stops, fleet maintenance terminals, independent garages, truck and commercial tire dealerships, truck quick lube facilities and other parts and service centers. We also compete with other full service restaurants, QSRs, mass merchandisers, electronics stores, drugstores, gasoline stations and convenience stores. Some truck fleets own their own fuel, and repair and maintenance facilities; however, we believe the long term trend has been toward a reduction in these facilities in favor of obtaining fuel, and repair and maintenance services from third parties like us. We believe that we are able to compete successfully because we offer consistent, high quality products and services, and our nationwide travel centers provide an advantage to large trucking fleets, particularly long haul trucking fleets, by enabling them to (i) take advantage of efficiencies afforded by the wide array of products and services our travel centers provide for their equipment and their drivers and (ii) reduce the number of their suppliers by routing their trucks through our travel centers nationwide.

An additional source of competition in the future could result from commercialization of state owned interstate highway rest areas. Some state governments have historically requested that the federal government allow these rest areas to offer fuel and nonfuel products and services similar to that offered at a travel center and certain congressional leaders have historically supported such legislation. If commercialized, these rest areas may increase the number of locations competing with us and these rest areas may have significant competitive advantages over existing travel centers, including ours, because they are generally located on restricted (i.e., toll) roads and have dedicated ingress and egress.

Convenience Stores

The convenience store industry is highly competitive with ease of entry and constant changes in the number and types of retailers offering products and services similar to those we offer. Fuel, food, including prepared foods, and nonfood items similar or identical to those sold by us are generally available from various competitors in the communities we serve, including other convenience store chains, independent convenience store operators, supermarkets, drug stores, discount clubs, motor fuel service stations, discount retail chains or independent stores, fast food operations, gasoline stations and other retail stores. We believe our stores compete principally with local grocery stores, restaurants, larger gasoline stations offering a more limited selection of grocery and food items for sale and other convenience stores. As of December 31, 2017 , the U.S. convenience store industry consisted of approximately 155,000 convenience stores. Based on the number of our locations, including the convenience store operations within our travel centers, we believe we currently are one of the 20 largest convenience store operators in the convenience store industry.

Our Leases with HPT

We have five leases with Hospitality Properties Trust, or HPT; four leases for an aggregate of 159 properties, which we refer to collectively as the TA Leases, and a fifth lease for 40 travel center properties, which we refer to as the Petro Lease. We refer to the four TA Leases and the Petro Lease collectively as the HPT Leases. One of our subsidiaries is a tenant under the leases, and we, and in the case of our TA Leases certain of our subsidiaries, guarantee the tenants' obligations under the leases. The following is a summary of the material terms of these leases, as amended.

Term. The TA Leases expire on December 31, 2026, 2028, 2029 and 2030, respectively. The Petro Lease expires on June 30, 2032 . We may extend each of these leases for up to two additional periods of 15  years.

Rent.  As of December 31, 2017 , the HPT Leases required us to pay aggregate minimum rent to HPT in an amount of $282.3 million per year. We may request that HPT purchase approved renovations, improvements and equipment additions we make at the leased properties, in return for an increase in our minimum annual rent equal to the amount paid by HPT times the greater of (i)  8.5% or (ii) a benchmark U.S. Treasury interest rate plus 3.5% . HPT is not required to purchase any improvements and we are not required to sell any improvements to HPT.

Percentage Rent. Under the HPT Leases, we incur percentage rent payable to HPT. The percentage rent is 3% of the excess of nonfuel revenues for any particular year over the percentage rent base year amount. HPT had agreed to waive payment of the first $2.5 million of percentage rent that may become due under our Petro Lease, and as of June 30, 2016, HPT had waived, in aggregate, all of the $2.5 million of percentage rent to be waived.

Deferred Rent. We owe deferred rent to HPT in an aggregate amount of $150.0 million , of which $42.9 million , $29.3 million , $29.1 million , $27.4 million and $21.2 million will be due and payable on June 30, 2024, and December 31, 2026 , 2028 , 2029 and 2030 , respectively. Interest does not accrue on this deferred rent obligation, subject to exceptions. This deferred rent obligation may be accelerated by HPT and become due on an earlier date and interest shall begin to accrue thereon upon the occurrence of certain events, including a change of control in us.

Maintenance and Alterations. We must maintain, at our expense, the leased properties, including maintenance of structural and non-structural components. At the end of each lease we must surrender the leased properties in substantially the same condition as existed at the commencement of the lease subject to any permitted alterations and reasonable wear and tear.

Assignment and Subletting.  HPT's consent is required for any direct or indirect assignment or sublease of any of the leased properties. We remain liable under the leases for subleased properties.

Indemnification and Insurance. With limited exceptions, we indemnify HPT for certain environmental matters and for liabilities that arise during the terms of the leases from ownership or operation of the leased properties. We generally must maintain commercially reasonable insurance. Our insurance coverage requirements include:

The HPT Leases generally require that HPT be named as an additional insured under our insurance policies.

Damage, Destruction or Condemnation.  If any leased property is damaged by fire or other casualty or taken by eminent domain, we are generally obligated to rebuild. If the leased property cannot be restored, (a) HPT will generally receive all insurance or taking proceeds, (b) in the case of a casualty loss, we are liable to HPT for any deductible or difference between the replacement cost and the amount of any insurance proceeds, and (c) the annual minimum rent will be reduced by (i) in the case of the TA Leases, at HPT's option, either 8.5% of the net proceeds paid to HPT or the fair market rental of the damaged, destroyed or condemned property, or portion thereof, as of the commencement date of the TA Leases; (ii) in the case of a casualty loss under the Petro Lease, 8.5% of the net proceeds paid to HPT plus the fair market value of the land; and (iii) in the case of a taking under the Petro Lease, 8.5% of the amount of the net proceeds paid to HPT.

Events of Default.  Events of default under each lease include the following:

Remedies. Following the occurrence of any event of default, each lease provides that, among other things, HPT may, to the extent legally permitted:

We are also obligated to reimburse HPT for all costs and expenses incurred in connection with any exercise of the foregoing remedies.

Lease Subordination.  Each lease may be subordinated to any mortgages of the leased properties by HPT, but HPT is required to obtain nondisturbance agreements for our benefit.

Financing Limitations; Security. Without HPT's prior written consent, our tenant subsidiaries may not incur debt secured by any of their assets used in the operation of the leased properties; provided, however, our tenant subsidiaries may incur purchase money debt to acquire assets used in these operations and we may encumber such assets to obtain a line of credit secured by our tenant subsidiaries' receivables, inventory or certain other assets used in these operations.

Lease Termination. When a lease terminates, any equipment, furniture, fixtures, inventory and supplies at the leased properties that we own may be purchased by HPT at its then fair market value. Also at termination of the TA Leases, HPT has the right to license any of our software used in the operation of the leased properties at its then fair market value and to offer employment to employees at the leased properties; and under the HPT Leases we have agreed to cooperate in the transfer of permits, agreements and the like necessary for the operation of the leased properties.

Territorial Restrictions. Under the terms of each lease, without the consent of HPT, we generally cannot own, franchise, finance, operate, lease or manage any travel center or similar property within 75  miles in either direction along the primary interstate on which a travel center owned by HPT is located.

Right of First Refusal. We have granted to HPT in the HPT Leases a right of first refusal to acquire or finance certain properties that we determine to acquire.

Non-Economic Properties. If during a lease term the continued operation of any leased property becomes non-economic in our reasonable determination and we and HPT cannot agree on an alternative use for the property, we may offer that property for sale, including the sale of HPT's interest in the property, free and clear of our leasehold interests. No sale of a property leased from HPT, however, may be completed without HPT's consent. In the event we obtain a bona-fide offer to purchase the property and HPT consents to the sale, the net sale proceeds received will be paid to HPT, exclusive of amounts associated with our personal property, which we can elect to sell to the buyers or keep, and the annual minimum rent payable shall be reduced. In the case of the TA Leases, this rent reduction will be, at HPT's option, either the amount of such proceeds times 8.5% or the fair market rental for such property as of the commencement date of the lease; in the case of the Petro Lease, this reduction will be the amount of such proceeds times 8.5%. If we obtain a bona-fide offer to purchase the property but HPT does not consent to the sale of the property, that property will no longer be part of the lease and the minimum rent will be reduced as if the sale had been completed at the amount offered. No more than a total of 15 properties subject to the TA Leases and no more than five properties subject to the Petro Lease may be offered for sale as non-economic properties during the applicable lease term.

Arbitration. Our leases with HPT also include arbitration provisions for the resolution of disputes, claims and controversies.

See Note 7 to the Notes to Consolidated Financial Statements in Item 15 of this Annual Report for more information about the terms of the HPT Leases and related amounts.

Relationships with Franchisees

We have lease and franchise agreements with lessees and owners of travel centers and standalone restaurants. We collect rent and franchise, royalty, advertising and other fees under these agreements. The table below summarizes by state information as of December 31, 2017 , regarding branding and ownership of the travel centers and standalone restaurants our franchisees operate and excludes travel centers and standalone restaurants we operate. The TA and Petro brand properties are included in our travel center segment and the QSL branded properties are included in corporate and other in our segment information. Information about the locations we operate is included in Item 2 of this Annual Report.

TA and Petro Franchise Agreements

Material provisions of our TA and Petro travel center franchise agreements typically include the following:

Initial Franchise Fee.  The initial franchise fee for a new TA or Petro franchise is $1.0 million .

Term of Agreement.  The initial term of a franchise agreement is generally 10 to 15 years. Our TA franchise agreements generally provide for two five year renewals on the terms then being offered to prospective franchisees at the time of the franchise renewal and our Petro franchise agreements generally provide for two five year renewals on the same terms as the expiring agreements. As of December 31, 2017 , our franchise agreements had an average remaining term excluding renewal options of five years and an average remaining term including renewal options of ten  years.

Protected Territory. Under the terms of our franchise agreements for TA travel centers, generally we have agreed not to operate, or allow another person to operate, a travel center or travel center business that uses the TA brand in a specified territory for that TA branded franchise travel center. Under the terms of our franchise agreements for Petro travel centers, generally we have agreed not to operate, or allow another person to operate, a travel center or travel center business that uses the Petro brand in a specified territory for that Petro branded franchise travel center.

Restrictive Covenants.  Generally our franchisees may not operate any travel center or truck stop related business under a franchise agreement, licensing agreement or marketing plan or system of another person or entity. If the franchisee owns the franchised premises, generally for a two year period after expiration or earlier termination of our franchise agreement the franchisee may not operate the premises under a competitive brand.

Nonfuel Product Offerings. Franchisees are required to operate their travel centers in conformity with guidelines that we establish and offer any products and services that we deem to be a standard product or service in our travel centers.

Fuel Purchases, Sales and Royalties. Our franchise agreements require the franchisee to pay us a royalty fee per gallon of fuel sold based on sales of certain fuels at the franchised travel center, unless they purchase their fuel inventory from us. We also purchase receivables generated by some of our franchisees in connection with sales to common trucking fleet customers through our proprietary billing system on a non-recourse basis in return for a fee.

Royalty Payments on Nonfuel Revenues.  Franchisees are required to pay us a royalty fee generally equal to between 2.0% and 4.0% of nonfuel revenues, in some cases up to a threshold amount, with a lower percentage fee payable on amounts in excess of the threshold amount and on revenues from branded QSRs.

Advertising, Promotion and Image Enhancement.  Our franchisees are required to make additional payments to us as contributions to the applicable brand wide advertising, marketing and promotional expenses we incur.

Termination/Nonrenewal.  Generally, we may terminate or refuse to renew a franchise agreement for default by the franchisee. Generally, we may also refuse to renew if we determine that renewal would not be in our economic interest or, in the case of TA franchisees and Petro franchisees under our current form of franchise agreement, if the franchisee will not agree to the terms in our then current form of franchise agreement.

Rights of First Refusal.  During the term of each franchise agreement, we generally have a right of first refusal to purchase that facility at the price offered to a franchisee by a third party. In addition, some of our agreements give us a right to purchase the franchised travel center for fair market value, as determined by the parties or an independent appraiser, upon expiration or earlier termination of the franchise agreement.

Franchisee Lease Agreements

In addition to franchise fees, we also collect rent from franchisees who lease their travel centers from us. At December 31, 2017 , there were four such leased franchisee travel centers. Two of the four franchisees exercised their final renewal term options and renewed their lease agreements during 2017; the terms of these two lease agreements expire in June 2022. The remaining two franchisees did not exercise their final renewal term options and, therefore, the related lease agreements expired during 2017. One of these franchisees has filed, and the other has indicated an intent to file, requests for a preliminary injunction preventing their eviction from the lease premises until such time as a court can determine whether we breached the terms of the leases by proposing rent increases for the final renewal term. As this matter proceeds through the courts, these two franchisees currently are operating under the terms of the expired lease agreements.

QSL Franchise Agreements

Material provisions of our QSL franchise agreements typically include the following:

Initial Franchise Fee.  The initial franchise fee for a new QSL franchise is $ 40.0 thousand . If a franchisee chooses to develop a location within a specified development area, the franchisee is required to pay an initial development fee of $20.0 thousand per restaurant.

Term of Agreement.  The initial term of a QSL franchise agreement is generally 10 to 20 years. Our QSL franchise agreements generally provide for a 10 year renewal on the terms then being offered to prospective franchisees at the time of the franchise renewal. As of December 31, 2017 , our franchise agreements had an average remaining term excluding renewal options of 11 years and an average remaining term including renewal options of 20  ye ars.

Protected Territory. Under the terms of our QSL franchise agreements, generally we have agreed not to operate, or allow another person to operate, a similar restaurant in a specified territory. In addition, the franchisees have agreed not to operate a similar restaurant within a specified territory, for a minimum of two years commencing on the effective date of the agreement.

Restaurant Offerings. Franchisees are required to operate their restaurants in conformity with the image of QSL and agree to prepare, sell and offer only those menu items that have been approved by us.

Royalty Payments on Net Revenues.  QSL franchisees are required to pay us a royalty fee on net revenues, which includes revenues of all goods and merchandise, or services, equal to between 4.0% to 5.0% .

Advertising, Promotion and Image Enhancement.  Our franchisees are required to make additional payments to us as contributions to the applicable brand wide advertising, marketing and promotional expenses we incur. In addition, franchisees are required to spend an agreed upon percentage of net revenues on local advertising.

Termination/Nonrenewal.  Generally, we may terminate or refuse to renew a franchise agreement for default by the franchisee.

Rights of First Refusal.  During the term of each franchise agreement, we generally have a right of first refusal to purchase that restaurant at the price offered to a franchisee by a third party.

Regulatory Environment

Environmental Regulation

Extensive environmental laws regulate our operations and properties. These laws may require us to investigate and clean up hazardous substances, including petroleum or natural gas products, released at our owned and leased properties. Governmental entities or third parties may hold us liable for property damage and personal injuries, and for investigation, remediation and monitoring costs incurred in connection with any contamination and regulatory compliance at our locations. We use both underground storage tanks and above ground storage tanks to store petroleum products, natural gas and other hazardous substances at our locations. We must comply with environmental laws regarding tank construction, integrity testing, leak detection and monitoring, overfill and spill control, release reporting and financial assurance for corrective action in the event of a release. At some locations we must also comply with environmental laws relative to vapor recovery or discharges to water. Under the terms of the HPT Leases, we generally have agreed to indemnify HPT for any environmental liabilities related to properties that we lease from HPT and we are required to pay all environmental related expenses incurred in the operation of the leased properties. Under an agreement with Shell, we have agreed to indemnify Shell and its affiliates from certain environmental liabilities incurred with respect to our travel centers where Shell has installed natural gas fueling lanes.

For further information about these and other environmental and climate change matters, see the disclosure under the heading "Environmental Contingencies" in Note 13 to the Notes to Consolidated Financial Statements included in Item 15 of this Annual Report. In addition, for more information about these environmental and climate change matters and about the risks which may arise as a result, see elsewhere in this Annual Report, including "Warning Concerning Forward Looking Statements," Item 1A, "Risk Factors," and Item 7, "Management's Discussion and Analysis - Environmental and Climate Change Matters."

Franchise Regulation

Subject to certain exemptions, the Federal Trade Commission regulations require that we make extensive disclosure to prospective franchisees and some states require state registration and delivery of specified disclosure documentation to potential franchisees. Some state laws also impose restrictions on our ability to terminate or not renew franchises and impose other limitations on the terms of our franchise relationships or the conduct of our franchise business. The Petroleum Marketing Practices Act imposes special regulations on franchises where petroleum products are offered for sale. Also, a number of states include, within the scope of their petroleum franchising statutes, prohibitions against price discrimination and other allegedly anticompetitive conduct. These provisions supplement applicable federal and state antitrust laws. We believe that we are in compliance with all franchise laws applicable to our business.

Gaming Regulation

Because we have gaming operations at some of our travel centers, we and our concerned subsidiaries are currently subject to gaming regulations in Illinois, Louisiana, Montana and Nevada. Requirements under gaming regulations vary by jurisdiction but include, among other things:

Holders of beneficial interests in our voting securities are subject to licensing or suitability investigations by the relevant gaming authorities under various circumstances including, generally, service on our Board of Directors, the attainment of certain levels of ownership of a class of our voting securities, or involvement in the gaming operations of or influence over us or our licensed subsidiaries. Persons or entities seeking to acquire control of us or our operation of the license are subject to prior investigation by and approval from the relevant gaming authorities. Any beneficial owner of our voting securities, regardless of the number of shares owned, may be required by a relevant gaming authority to file an application and have their suitability reviewed in certain circumstances, including if the gaming authority has reason to believe that such ownership of our voting securities would otherwise be inconsistent with its state's gaming laws. In some jurisdictions, the applicant must pay all costs of investigations incurred in connection with such investigations. Additionally, in the event of a finding by a relevant gaming authority that a person or entity is unsuitable to be an owner of our securities, such person would be prohibited from, among other things, receiving any dividend or interest upon such securities, exercising any voting right conferred through such securities or continuing to hold our securities beyond such period of time as may be prescribed by such gaming authority, managing the licensed business and, in some cases, the shareholder may be required to divest himself or itself of our voting securities.

Certain of our and our subsidiaries' directors and officers must also file applications, be investigated and be licensed or found suitable by the relevant gaming authorities in order to hold such positions. In the event of a finding by a relevant gaming authority that a director, officer, key employee or individual with whom we or our licensed subsidiary have a material relationship is unsuitable, we or our licensed subsidiary, as applicable, may be required to sever our relationships with such individual or such individual may be prohibited from serving as our director or officer.

Any violations by us or any of our licensed subsidiaries of the gaming regulations to which we are subject could result in fines, penalties (including the limiting, conditioning, suspension or revocation of any licenses held) and criminal actions. Additionally, certain jurisdictions, such as Nevada, empower their regulators to investigate participation by licensees in gaming outside their jurisdiction and require access to periodic reports regarding those gaming activities. Violations of laws in one jurisdiction could result in disciplinary action in other jurisdictions.

We have a Gaming Compliance Plan, or the Compliance Plan, as required by the Nevada Gaming Commission in connection with our gaming operations at certain of our travel center locations. In connection with the Compliance Plan we have a Gaming Compliance Committee, or the Compliance Committee, on which a member of our Audit Committee of the Board of Directors serves as the Board of Directors' liaison to the Compliance Committee pursuant to the terms of the Compliance Plan. The Compliance Committee assists us in monitoring activities relating to our continuing qualifications under applicable gaming laws.

Seasonality

Our sales volumes are generally lower in the first and fourth quarters than the second and third quarters of each year. In the first quarter, the movement of freight by professional truck drivers as well as motorist travel are usually at their lowest levels of each calendar year. In the fourth quarter, freight movement is typically lower due to the holiday season. While our revenues are modestly seasonal, the quarterly variations in our operating results may reflect greater seasonal differences as our rent and certain other costs do not vary seasonally.

Intellectual Property

We own the "Petro Stopping Centers," "Minit Mart" and "Quaker Steak & Lube" names and related trademarks and various trade names used in our business including RoadSquad®, RoadSquad OnSite®, TA Commercial Tire Network™, UltraOne®, Iron Skillet®, Reserve-It!®, eShop® and others. We have the right to use the "TA," "TravelCenters of America," Country Pride® and certain other trademarks, which are owned by HPT, during the terms of each of the four TA Leases. We also license certain trademarks used in the operation of certain of our restaurants and convenience stores. We believe that these trademarks are important to our business, but that they could be replaced with alternative trademarks without significant disruption in our business except for the cost of such changes, which may be significant.

Item 1A. Risk Factors

Our business faces many risks. If any of the events or circumstances described in the following risks occurs, our business, financial condition or results of operations could suffer and the market prices of our equity or debt securities could decline. Investors and prospective investors should carefully consider the following risks, the risks referred to elsewhere in this Annual Report and the information contained under the heading "Warning Concerning Forward Looking Statements" before deciding whether to invest in our securities.

Risks Related to Our Business

Our operating margins are narrow .

Our operating margins are low. Fuel sales comprise the majority of our revenues and generate low gross margin percentages. A small percentage decline in our future revenues or increase in our future costs, especially revenues and costs and expenses related to fuel, may cause our profits to decline or us to incur losses. Fuel prices and sourcing have historically been volatile, which may increase the risk of declines in revenues or increases in costs. In the years during the U.S. economic recession and periods of historically high and volatile fuel prices, we realized large operating losses. Shifts in customer demand for our products and services, including as a result of increased fuel conservation practices, or heightened competition could cause our operating margins to narrow further and we may incur losses. Our operating margins will also be negatively impacted by any increase in transaction or other fees we are required to pay to fuel card providers that we cannot pass along to our customers.

Increasing fuel efficiency of motor vehicle engines and use of other fuel conservation practices and alternative fuels may adversely impact our business.

Truck and other vehicle manufacturers and our trucking and motorist customers continue to be focused on technological innovations to improve motor vehicle fuel efficiency and conserve fuel. The development of new technologies, such as truck platooning (the electronic linking of trucks with a lead vehicle), heat and kinetic energy recovery technologies, and substantially lighter "super trucks," and higher efficiency motor fuels could result in significant increases in fuel efficiency. In addition, advances in alternative fuel technologies may lead to their greater adoption by the trucking industry and other motorists. Government regulation may encourage or require the improved fuel efficiency of motor vehicle engines, other fuel conservation practices and alternative fuels. The largest part of our business consists of selling motor fuel. If our trucking or other customers purchase less motor fuel because their trucks or other vehicles operate more fuel efficiently or use alternative fuels, our financial results will decline and we may incur losses unless we are able to sufficiently offset the declines by selling substitute or other products or services, gaining market share, increasing our gross margins per gallon of fuel sold or reducing our operating costs. It is unclear whether we will be able to operate our travel centers profitably if the amount of motor fuels used by the U.S. trucking industry or other motorists declines.

Our financial results are affected by U.S. trucking and restaurant industry economic conditions.

The trucking industry is the primary customer for our goods and services. Demand for trucking services in the United States generally reflects the amount of commercial activity in the U.S. economy. When the U.S. economy declines, demand for goods moved by trucks declines, and in turn demand for our products and services typically declines, which could have an adverse effect on our results of operations and financial condition.

Our restaurant business is important to our financial results. Our travel centers offer full service restaurants and QSRs, many of our convenience stores offer QSRs and our business includes standalone restaurants. The restaurant industry is often affected by changes in consumer tastes, national, regional and local economic conditions, discretionary spending priorities, demographic trends, traffic patterns and the type, number and location of competing businesses. Downturns in the restaurant industry caused by any of the foregoing may materially negatively affect our business and results of operations.

The industries in which we operate are highly competitive.

We believe that large trucking fleets and long haul trucking fleets tend to purchase the large majority of their fuel at travel centers and truck stops that are located at or near interstate highway exits from us or our largest competitors. Based on the number of locations, we, Pilot and Love's are the largest companies in the travel center industry. These competitors may have greater financial and other resources than we do, which may facilitate their ability to compete more effectively. Increased competition between the major competitors in the travel center and truck stop business could result in a reduction of our gross margins or an increase in our expenses or capital improvement costs, which could negatively affect our profitability and our liquidity.

Further, the truck repair and maintenance service industry is highly competitive. Such services can be obtained by trucking companies and truck drivers from a variety of sources, including national and regional truck repair and maintenance facilities, full service travel centers, truck stop chains, fleet maintenance terminals, independent garages, truck and commercial tire dealerships, truck quick lube facilities and other parts and service centers. In addition, some trucking companies operate their own terminals to provide repair and maintenance services to their own trucking fleets and drivers. Pilot and Love's, our two largest competitors, have increased their respective numbers of truck repair and maintenance facilities over the past several years and should this trend continue, our competitive position could be weakened. Some of our competitors in the truck repair and maintenance service business may have more resources or lower costs than we do and vertically integrated businesses which may provide them competitive advantages.

The convenience store industry in the United States and in the geographic areas in which we operate is also highly competitive and fragmented with ease of entry and constant change in the number and types of retailers offering the products and services similar to those we provide. We compete with other convenience store chains, independent convenience stores, supermarkets, drugstores, discount clubs, motor fuel service stations, mass merchants, fast food operations and other similar retail outlets. Several non-convenience store retailers, such as supermarkets, club stores and mass merchants, compete directly with convenience stores, particularly in the sale of motor fuel, and their market share is expected to continue to grow. Increased competition or new entrants to the industry could result in reduction of our gross margins. Based on the number of our locations, we are not one of the largest companies in the convenience store industry. In addition, large retailers such as Amazon.com, Inc. and Walmart Inc. have announced plans to enter the convenience store market and have begun doing so.

We also face competition from restaurants in the quick service and casual dining segments of the restaurant industry. These segments are highly competitive and fragmented. Our competition includes a variety of locally owned restaurants and national and regional chains offering dine-in, carry-out, delivery and catering services. Many of our competitors have existed longer and have a more established market presence with substantially greater financial, marketing, personnel and other resources than we do. Among our competitors are a number of multi-unit, multi-market, fast casual restaurant concepts, some of which are expanding nationally. These competitors may have, among other things, lower operating costs, better locations, facilities or management, more effective marketing and more efficient operations.

Any inability to successfully compete effectively will reduce customer traffic and sales at our locations and may prevent us from sustaining or increasing our revenue or improving our profitability.

Disruptive technologies in the energy or transportation industries may materially harm our business.

The major product we sell is fuel. Another significant part of our business is the sale of nonfuel products and services to drivers who visit our locations, often in connection with purchasing fuel. Various technologies are being developed in the energy and transportation industries that, if widely adopted, may materially harm our business. For example, electric motor vehicle engines that do not require diesel fuel and hybrid electric-diesel/gasoline engines may require substantially less diesel/gasoline fuel per mile driven. Further, driverless motor vehicle technologies may result in fewer individual drivers on the U.S. interstate highways and reduce the customer traffic and sales of fuel and nonfuel products at our locations. Such reductions may materially and adversely affect our sales and our business.

Privatization of toll roads or of rest areas may negatively affect our business.

Some states have privatized their toll roads that are part of the interstate highway system. We believe it is likely that tolls will increase on privatized highways. In addition, some states may increase tolls for their own account. If tolls are introduced or increased on highways in the proximity of our locations, our business at those travel centers may decline because truck drivers and motorists may seek alternative routes. Similarly, some states have privatized or are considering privatizing their publicly owned highway rest areas. If publicly owned rest areas along highways are privatized and converted to travel centers in the proximity of some of our locations, our business at those locations may decline and we may experience losses.

On February 12, 2018, the Trump Administration, or the Administration, announced its proposal for a $1.5 trillion infrastructure plan that contains several policy provisions detrimental to the truck stop industry and our business. Specifically, the Administration's proposal intends to shift the responsibility for financing infrastructure projects from the federal government to the states and the private sector; such shifting is expected to greatly increase tolling of U.S. highways. The Administration also proposed rest area commercialization. While it is uncertain the Administration's proposal will find sufficient Congressional support to be enacted, if enacted as proposed the Administration's plans are likely to adversely affect our business, possibly significantly.

We have a substantial amount of indebtedness and rent obligations, which could adversely affect our financial condition.

Our indebtedness and rent obligations are substantial. The terms of our leases with HPT require us to pay all of our operating costs and generally fixed amounts of rent. During periods of business decline, our revenues and gross margins may decrease but our minimum rents due to HPT and the interest payable on our indebtedness do not decline proportionately or at all. A decline in our revenues or an increase in our expenses may make it difficult or impossible for us to make payments of interest and principal on our debt or meet our rent obligations and could limit our ability to obtain financing for working capital, capital expenditures, acquisitions, refinancing, lease obligations or other purposes. Our substantial indebtedness and rent obligations may also increase our vulnerability to adverse economic, market and industry conditions, limit our flexibility in planning for, or reacting to, changes in our business operations or to our industry overall, and place us at a disadvantage in relation to competitors that have lower relative debt levels. If we default under our HPT leases, we may be unable to continue our business. Any or all of the above events and factors could have an adverse effect on our results of operations and financial condition.

Fuel price increases and fuel price volatility could negatively affect our business.

Increasing fuel prices and fuel price volatility have several adverse impacts upon our business. First, high fuel prices result in higher truck shipping costs. This causes shippers to consider alternative means for transporting freight, which reduces trucking business and, in turn, reduces our business. Second, high fuel prices cause our trucking customers to seek cost savings throughout their businesses. This has resulted in the implementation by many of our customers of measures to conserve fuel, such as purchasing trucks that have more fuel efficient engines, employ alternative fuel or other technologies, lowering maximum driving speeds and employing other practices to conserve fuel, such as truck platooning and reduced truck engine idling, which measures reduce total fuel consumption and in turn reduce our fuel sales. Third, higher fuel prices may result in less disposable income for our customers to purchase our nonfuel goods and services. Fourth, higher and more volatile fuel commodity prices increase the working capital needed to maintain our fuel inventory and receivables, and this increases our costs of doing business. Further, increases in fuel prices may place us at a cost disadvantage to our competitors that may have larger fuel inventory or forward contracts executed during periods of lower fuel prices. If fuel commodity prices or fuel price volatility increase, our financial results may not improve and may worsen.

There is limited competition among third party fuel card companies and continued litigation with fuel card provider FleetCor could adversely affect our business.

Most of our trucking customers transact business with us by use of fuel cards, which are issued by third party fuel card companies. The fuel card industry has only two significant participants, FleetCor and WEX. According to a published analyst report, FleetCor and WEX collectively account for more than 80% of the fuel card provider market. We believe almost all trucking companies use only a single fuel card provider and have become increasingly dependent upon the data, reports and other services provided by their respective fuel card provider to manage their fleets and simplify their data processing. Fuel card providers have direct negotiated contractual relationships with their trucking company customers. We cannot easily substitute an alternative fuel card for trucking companies to use to acquire fuel at our locations. Any effort to convince trucking companies to use an alternative card at our locations requires significant time, expense and coordination with the provider of that alternative card, and may not be successful.

Additionally, if fuel card issuers raise the fees we are required to pay when their respective contracts are renewed, we may not be able to recover the increased expense through higher prices to customers, and our business, financial condition and results of operations may be materially adversely affected.

As described under the heading "Legal Proceedings" in Note 13 to the Notes to Consolidated Financial Statements included in Item 15 of this Annual Report, we and FleetCor's subsidiary Comdata are parties to a merchant agreement, or the Merchant Agreement, which Comdata purported to terminate in November 2016. From February 1, 2017, until mid-September 2017, Comdata unilaterally increased the fees it withheld from the transaction settlement payments due to us under such agreement. On September 11, 2017, the Court of Chancery of the State of Delaware, or the Court, issued an opinion stating that we are entitled to, among other things, an order requiring Comdata to specifically perform under the Merchant Agreement, and awarded damages to us and against Comdata for, among other things, the difference between the higher transaction fees we had paid to Comdata since February 1, 2017, and what we should have paid during this period under the fee schedule in the Merchant Agreement. After a final order is entered, Comdata may appeal the Court's judgment and the Court's decision may be reversed or amended upon appeal. If we do not prevail in any appeal brought by FleetCor and Comdata and, upon appeal, it is determined that Comdata validly terminated our agreement, we may not be able to obtain a new agreement with FleetCor and Comdata, and we may lose a material amount of future business from our customers who use FleetCor or Comdata issued payment cards, resulting in material harm to our business, financial condition and results of operations. Any continuation of this litigation will be distracting to our management and expensive.

Climate change and other environmental legislation and regulation and market reaction thereto may decrease demand for our major product, diesel fuel, and require us to make significant changes to our business and to make capital or other expenditures, which may adversely affect our business .

Climate change and other environmental legislation and regulation, including those addressing greenhouse gas emissions, and market reaction to any such legislation or regulation or to climate change concerns, may decrease the demand for our major product, diesel fuel, and may require us to make significant capital or other expenditures. Federal and state governmental requirements addressing emissions from trucks and other motor vehicles, such as the U.S. Environmental Protection Agency's, or the EPA's, gasoline and diesel sulfur control requirements that limit the concentration of sulfur in motor fuel, could negatively impact our business. Further, legislative and regulatory initiatives requiring increased truck fuel efficiency have accelerated in the United States and these mandates have and may continue to result in decreased demand for diesel fuel, which could have a material adverse effect on our business, financial condition and results of operations. For example, in August 2016 the EPA and the National Highway Traffic Safety Administration established final regulations that will phase in more stringent greenhouse gas emission and fuel efficiency standards for medium and heavy duty trucks beginning in model year 2021 (model year 2018 for certain trailers) through model year 2027, and these regulations are estimated to reduce fuel usage between 9% and 25% (depending on vehicle category) by model year 2027. Regulations that limit carbon emissions may also cause our costs at our locations to increase, make some of our locations obsolete or require us to make material investments in our properties. Increased costs incurred by our suppliers as a result of climate change or other environmental legislation or regulation may be passed on to us in the prices we pay for our fuel supplies, but we may not be able to pass on those increased costs to our customers. Increased fuel costs resulting from these reasons would likely have similar effects on our business, operations and liquidity as discussed elsewhere regarding high fuel costs, including decreased demand for our fuel at our locations, increased working capital needs and decreased fuel gross margins. Moreover, as described elsewhere in this Annual Report, technological changes or changes in customer transportation or fueling preferences, including as a result of or in response to climate change or other environmental legislation or regulation or the market reaction thereto, may require us to make significant changes to our business and to make capital or other expenditures to adopt those technologies or to address those changed preferences and may decrease the demand for products and services sold at our locations.

An interruption in our fuel supplies would materially adversely affect our business.

To mitigate the risks arising from fuel price volatility, we generally maintain limited fuel inventory. Accordingly, an interruption in our fuel supplies would materially adversely affect our business. Interruptions in fuel supplies may be caused by local conditions, such as a malfunction in a particular pipeline or terminal, by weather related events, such as hurricanes in the areas where petroleum or natural gas is extracted or refined, or by national or international conditions, such as government rationing, acts of terrorism, wars and the like. Further, our fuel suppliers may fail to provide us with fuel due to these or other reasons. Any limitation in available fuel supplies or on the fuel we can offer for sale may cause our profits to decline or us to experience losses.

Our growth strategies and our locations require regular and substantial capital investment. We may be unable to access the capital necessary to invest in our locations or fund acquisitions.

Our growth strategies and business depend upon our ability to raise additional capital at reasonable costs to invest in our locations and to fund acquisitions and investments that we believe are important to expand our business and maintain our competitiveness. All of our travel centers and many of our convenience stores are open for business 24 hours per day, 365 days per year. Due to the nature and intensity of the uses of our locations, they require regular and substantial expenditures for maintenance and capital investments to remain functional and attractive to customers. Although we may request that HPT purchase future renovations, improvements and equipment at the properties that we lease from HPT, HPT is not obligated to purchase any amounts and such purchases only relate to improvements to facilities leased from HPT by us and not to facilities that we have acquired and own or to general business improvements, such as improvements to our information technology networks and systems, or IT systems.

We may be unable to raise reasonably priced capital because of reasons related to our business, market perceptions of our prospects, the terms or amount of our outstanding indebtedness, the terms or amount of our rent obligations or for reasons beyond our control, such as market conditions. Moreover, there is potential for volatility in the availability of business capital on a global basis and in debt and equity markets generally. If we are unable to raise reasonably priced capital, our businesses and profits may decline and our growth strategies may fail.

Our storage and dispensing of petroleum products create the potential for environmental damages, and compliance with environmental laws is often expensive.

Our business is subject to laws relating to the protection of the environment. The travel centers and convenience stores we operate include fueling areas, truck repair and maintenance facilities and tanks for the storage and dispensing of petroleum products, waste and other hazardous substances, all of which create the potential for environmental damage. Environmental laws expose us to the possibility that we may become liable to reimburse governments or others for damages and costs they incur in connection with environmental hazards or liable for fines and penalties for failure to comply with environmental laws. We cannot predict what environmental legislation or regulations may be enacted or how existing laws or regulations will be administered or interpreted with respect to our products or activities in the future; more stringent laws, more vigorous enforcement policies or stricter interpretation of existing laws in the future could cause us to expend significant amounts or experience losses.

Under the leases between us and HPT, we generally have agreed to indemnify HPT from environmental liabilities it may incur arising at any of the properties we lease from HPT. Although we maintain insurance policies which cover our environmental liabilities, that coverage may not adequately cover liabilities we may incur. To the extent we incur material amounts for environmental matters for which we do not receive insurance or other third party reimbursement or for which we have not recognized a liability in prior years, our operating results may be materially adversely affected. In addition, to the extent we fail to comply with environmental laws and regulations, or we become subject to costs and requirements not similarly experienced by our competitors, our competitive position may be harmed. Also, to the extent we are or become obligated to fund any such liabilities, such funding obligation could materially adversely affect our liquidity and financial position.

We rely upon trade creditors for a significant amount of our working capital and the availability of alternative sources of financing may be limited.

Our fuel purchases are our largest operating cost. Historically, we have paid for our fuel purchases after delivery. In the past, as our fuel costs increased with the increase in commodity market prices, some of our fuel suppliers were unwilling to adjust the amounts of our available trade credit to accommodate the increased costs of the fuel volumes that we purchased. Also, our historical financial results and general U.S. economic conditions have caused some fuel suppliers to request letters of credit or other forms of security for our purchases. We cannot predict how high or low fuel prices may be in the future, or to what extent our trade creditors will be willing to adjust the amounts of our available trade credit to accommodate increased fuel costs. Fuel commodity prices significantly impact our working capital requirements, and the unavailability of sufficient amounts of trade credit or alternative sources of financing to meet our working capital requirements could materially adversely affect our business.

We rely on information technology in our operations, and any material failure, inadequacy, interruption or security failure of information technology could harm our business.

We rely on IT systems, including the internet, to process, transmit and store electronic information, including financial records and personally identifiable information such as employee and payroll data and workforce scheduling information, and to manage or support a variety of business processes, including our supply chain, retail sales, credit card payments and authorizations, financial transactions, banking and numerous other processes and transactions. We purchase some of the IT systems we use from vendors on whom our IT systems materially depend. We rely on commercially available and proprietary IT systems, software, tools and monitoring to provide security for processing, transmission and storage of confidential customer information, such as payment card and credit information. In addition, the IT systems we use for transmission and approval of payment card transactions, and the technology utilized in payment cards themselves, may put payment card data at risk; and some of these IT systems are determined and controlled by the payment card suppliers and not by us. Although we take various actions to protect and maintain the security of the IT systems we use and the data maintained in them, it is possible that our security measures will not prevent the improper functioning of or damage to the IT systems we use, or the improper access to such IT systems or disclosure of personally identifiable or confidential information, such as in the event of a cyber attack. Security breaches, including physical or electronic break ins, computer viruses, attacks by hackers and similar breaches, can create system disruptions, shutdowns or unauthorized disclosure of confidential information. Any compromise or breach of our IT systems could cause material interruptions in our operations, damage our reputation, require significant expenditures to determine the severity and scope of the breach, subject us to material liability claims, material claims of banks and credit card companies or regulatory penalties, reduce our customers' willingness to conduct business with us and could have a material adverse effect on our business, financial condition and results of operations. Moreover, if we have not adopted technologies to support chip and signature credit and charge cards by the deadline set by the credit card companies, those companies may not pay us for fraudulent transactions occurring at our locations with those companies' cards. Further, the failure of the IT systems we use to operate effectively, or problems we may experience with maintaining the IT systems we currently use or transitioning to upgraded or replacement systems, could significantly harm our business and operations and cause us to incur significant costs to remediate such problems.

Many of our labor costs cannot be easily reduced without adversely affecting our business.

To maintain and manage our operations requires certain minimum staffing levels to operate our travel centers and certain convenience stores 24 hours per day, 365 days per year, and we attempt to manage our staffing to avoid excess, unused capacity. As a result, it may be difficult for us to affect future reductions in our staff without adversely affecting our business prospects. Further, passage of federal and state legislation that results in increases to our labor costs, such as minimum wage increases and health insurance requirements, could result in higher labor costs than we currently anticipate. Certain aspects of our business require higher skilled personnel, such as truck service technicians. Hiring, training and maintaining higher skilled personnel can be costly, particularly if turnover is high. Further, as we grow our business, particularly the aspects of our business that require higher skilled personnel, we may experience increased difficulty with staffing those positions with qualified personnel and may incur greater costs to do so. Also, certain opportunities for sales may be lost if staffing levels are reduced too much or if we are unable to maintain a sufficient number of higher skilled employees. In addition, costs for health care and other benefits, due to regulation, market factors or otherwise, may further increase our labor costs.

If the company is unable to attract, motivate and retain experienced and knowledgeable personnel in key positions, its future results could be adversely impacted.

The success of our business is dependent upon our ability to employ and train individuals with the requisite knowledge, skills and experience to execute our business model and achieve our business objectives. The failure of the company to attract, motivate and retain key personnel or implement an appropriate succession plan, including in connection with the retirement of our former President and Chief Executive Officer, Thomas M. O'Brien, could adversely impact our ability to successfully carry out our business strategy and retain other key personnel.

Unfavorable publicity could negatively affect our results of operations as well as our future business.

We operate our travel centers, convenience stores and standalone restaurants under a small number of brand names. We sell gasoline under brands we do not own at most of our locations and many of our locations have QSRs operating under brands we do not own. In addition, we resell numerous other products we obtain from third parties. If we or the companies or brands associated with our products and offerings become associated with negative publicity, including as a result of customer or employee complaints, our customers may avoid purchasing our products and offerings at our locations because of our association with the particular company or brand. In recent years there has been an increase in the use of social media, which allows individuals access to a broad audience. The availability of information on social media is virtually immediate in its impact. The use of social media by our customers, employees or other individuals to make negative statements about our products, offerings, service, brands or other matters associated with us could quickly damage our reputation and negatively impact our revenues, and we may not be able to quickly and effectively address or counter the negative publicity. As noted elsewhere in this Annual Report, the control we may exercise over our franchisees is limited. Negative publicity or reputational damage relating to any of our franchisees may be imputed to our entire company and business. If we were to experience these or other instances of negative publicity or reputational damage, our sales and results of operations may be harmed.

Changes in U.S. trade policies could significantly reduce the volume of imported goods into the United States, which may materially reduce truck freight volume in the United States and our sales.

The Trump administration and members of the U.S. Congress have made public statements indicating possible significant changes in U.S. trade policy and have taken certain actions that may impact U.S. trade, including imposing tariffs on certain goods imported into the United States. Any changes in U.S. trade policy could trigger retaliatory actions by affected countries, resulting in "trade wars," in increased costs for goods imported into the United States, which may reduce customer demand for these products if the parties having to pay those tariffs increase their prices, or in trading partners limiting their trade with the United States. If these consequences are realized, the volume of economic activity in the United States, including trucking freight volume, may be materially reduced. Such a reduction may materially and adversely affect our sales and our business. Further, the realization of these matters may increase our cost of goods and, if those costs cannot be passed on to our customers, our business and profits may be materially and adversely affected.

The trucking industry may fail to satisfy market demands for transporting goods or market participants may choose other means to transport goods.

The trucking industry has been experiencing a shortage of qualified truck drivers and trucks. Further, increased regulations on the activities of truck drivers and trucking companies, including increased monitoring and enforcement of the number of hours truck drivers may operate a truck each day, and other matters have limited the ability of trucking companies to satisfy market demands for transporting goods. In addition, other means of transporting goods besides by truck are available, and new means of transportation may be under development. For example, there have been general news reports of other means of transportation being increasingly explored, such as light rail, airplanes and drones. If the trucking industry is unable to satisfy market demands for transporting goods or if the use of other means of transporting goods increases, the trucking industry may experience reduced business, which would negatively affect our business, results of operations and liquidity.

Food safety and foodborne illness concerns could have an adverse effect on our business.

We cannot guarantee that our controls and training will be fully effective in preventing all food safety issues at our QSRs, full service restaurants or our standalone restaurants, including any occurrences of foodborne illnesses. Some foodborne illness incidents could be caused by third-party vendors and transporters outside of our control. New illnesses resistant to our current precautions may develop in the future, or diseases with long incubation periods could arise, that could give rise to claims or allegations. One or more instances of foodborne illness in any of our quick service or standalone restaurants or related to food products we offer could negatively affect our sales and results of operations if it involves serious illness or is highly publicized. This risk exists even if it were later determined that the illness was wrongly attributed to us or one of our standalone restaurants or convenience store or travel center locations. A number of restaurant chains have experienced incidents related to foodborne illnesses that have had a material adverse effect on their operations. The occurrence of a similar incident at one or more of our locations, or negative publicity or public speculation about an incident, could have a material adverse effect on our business, financial condition and results of operations.

Territorial restrictions placed on us by our leases with HPT and our franchise agreements with our franchisees could impair our ability to grow our business.

Under our leases with HPT, without the consent of HPT, we generally cannot own, franchise, finance, operate, lease or manage any travel center or similar property within 75 miles in either direction along the primary interstate on which a travel center owned by HPT is located. Additionally, under our leases with HPT, we have granted HPT a right of first refusal on the properties that are the subject of such leases. Under the terms of our franchise agreements for TA travel centers, generally we have agreed not to operate, or allow another person to operate, a travel center or travel center business that uses the TA brand in a specified territory for that TA branded franchise location. Under the terms of our franchise agreements for Petro travel centers, generally we have agreed not to operate, or allow another person to operate, a travel center or travel center business that uses the Petro brand in a specified territory for that Petro branded franchise location. As a result of these restrictions, we may be unable to develop, acquire or franchise a travel center in an area in which an additional travel center may be profitable, thereby losing an opportunity for future growth of our business.

Labor disputes or other events may arise that restrict, reduce or otherwise negatively impact the movement of goods in the United States, which may adversely impact parts of the trucking industry that are our customers and may adversely impact our financial results at travel centers we operate.

A meaningful aspect of the U.S. trucking industry involves the movement of goods across the United States. Events that restrict, reduce or otherwise negatively impact the movement of those goods may adversely impact the trucking industry. In recent years, there were extended labor disputes at U.S. west coast ports which slowed the loading and unloading of goods at those ports. A large percentage of the goods which are loaded and unloaded at those ports are transported to and from those ports by trucking companies, including some who are our customers. Future labor disputes could disrupt the transportation of goods across the United States and remain unresolved for a prolonged period. Such a disruption may materially and adversely affect our business and our ability to operate profitable travel centers and meet our rent obligations may be adversely affected.

Changes in tax laws or other actions could have a negative effect on us.

At any time, the federal or state income tax laws, or the administrative interpretations of those laws, may be revised. Federal and state tax laws are constantly under review and interpretation by persons involved in the legislative process, the U.S. Internal Revenue Service, the U.S. Department of the Treasury and state taxing authorities. Changes to the tax laws, regulations and administrative interpretations, which may have retroactive application, could adversely affect us.

In particular, in December 2017, the Tax Cuts and Jobs Act became law, making substantial changes to the U.S. Internal Revenue Code of 1986, as amended, or the Code, especially as it relates to the taxation of both corporate income and international income. Among those changes are a significant permanent reduction in the generally applicable corporate income tax rate and the elimination or modification of various deductions, such as for executive compensation and interest expense above certain thresholds. The new legislation generally limits business interest expense deductions to 30% of a taxpayer's adjusted taxable income for a taxable year, and beginning in 2022 this limitation will become more stringent as it will be determined after application of any deduction for depreciation, amortization, or depletion. Additionally, the legislation also imposes additional limitations on the deduction of net operating losses. The effects of these and other changes made in this legislation are highly complex; as such, we have not fully evaluated all the implications the changes to the Code may have on our income tax expense or payments. Furthermore, many of the provisions of the new law will require guidance through the issuance of Treasury regulations in order to fully implement them and assess their effect on us. There may be a substantial delay before such regulations are promulgated, thus leaving the uncertainty as to the ultimate effect of the statutory amendments to persist for an unknown period. It is also possible that there will be technical corrections legislation proposed with respect to the new law, the effect of which cannot be predicted and may be adverse to us.

We may be unable to utilize our net operating loss and tax credit carryforwards.

Net operating losses and other carryforwards are subject to limitations stemming from the December 2017 amendments to the Code providing that carryforwards of net operating losses arising in taxable years beginning after 2017 generally cannot offset more than 80% of the current year's taxable income. Moreover, pursuant to the December 2017 amendments to the Code, net operating losses arising in taxable years beginning after 2017 may not be carried back, but may be carried forward indefinitely. These limitations could affect our ability to utilize all of our existing net operating loss and tax credit carryforwards.

If we experience an ownership change, our net operating loss and tax credit carryforwards, which currently are expected to be utilized to offset future taxable income, may be subject to limitations on usage or elimination. Our bylaws impose certain restrictions on the transfer of our shares in order to help us preserve the tax treatment of our net operating losses and other tax benefits (see below for a discussion of the risks related to our ownership limitations under the heading "Risks Arising from Certain of Our Relationships and Our Organization and Structure").

Changes in lease accounting standards may materially and adversely affect us.

The Financial Accounting Standards Board recently adopted new accounting rules, to be effective for our fiscal year ending December 31, 2019, that will require companies to capitalize all leases on their balance sheets by recognizing a lessee's rights and obligations. When the rules are effective, we expect we will be required to account for substantially all of our leases under which we are the lessee as assets and liabilities on our balance sheet, while currently we account for such leases on an "off balance sheet" basis. As a result, a significant amount of lease related assets and liabilities will be recognized in our balance sheets and we may be required to make other changes to the recording and classification of our lease related expenses. Though these changes will not have any direct impact on our overall financial condition or contractual payment or other obligations, these changes could cause investors or others to change the way they view our financial condition and could change the calculations of financial metrics and covenants, as well as third party financial models regarding our financial condition.

Our business could be adversely impacted if there are deficiencies in our disclosure controls and procedures or our internal control over financial reporting.

The design and effectiveness of our disclosure controls and procedures and our internal control over financial reporting may not prevent all errors, misstatements or misrepresentations. While our management will continue to review the effectiveness of our disclosure controls and procedures and our internal control over financial reporting, there can be no guarantee that our disclosure controls and procedures and internal control over financial reporting will be effective in accomplishing all control objectives all of the time. Deficiencies, including any material weaknesses, in our disclosure controls and procedures or internal control over financial reporting could result in misstatements of our results of operations or our financial statements or could otherwise materially and adversely affect our business, reputation, results of operations, financial condition or liquidity.

Risks Related to Our Acquisition and Growth Strategies

Acquisitions may be more difficult, costly or time consuming than expected and the anticipated benefits of our growth strategies or any particular transaction may not be fully realized.

Businesses and properties that we acquire often require substantial improvements in order to be brought up to our standards or to achieve our expected financial results. For example, improvements to our acquired travel centers are often extensive and require an extended period of time to plan, design, permit and complete, which is then followed by another period of time for the acquired travel center to become part of our customers' supply networks. Many locations we have acquired, and may in the future acquire, produced, or may produce, operating results before our acquisition that caused, or may cause, the prior owners to exit these businesses. Despite our efforts, the actual results of acquired properties may not improve under our management and may vary greatly from the results we expected when we made the acquisitions. These variances may occur due to many factors, including competition, the cost of improvements exceeding our estimates and our realization of less synergies and less cost savings than expected. Some of these factors are outside our control. If improvements are more difficult, costly or time consuming than expected or if reaching maturity takes longer than expected or does not occur at all, our business, financial condition or results of operations could be negatively affected.

The success of our growth strategies, such as our expansion into the convenience store and standalone restaurant business, and any particular acquisition, including the realization of anticipated benefits, synergies and cost savings, will depend, in part, on our ability to successfully combine acquired businesses with ours. Integration of acquired businesses may be more difficult, costly or time consuming than expected, may result in the loss of key employees or business disruption to us, or may adversely affect our ability to maintain relationships with customers, suppliers and employees or to fully achieve the anticipated benefits of the growth strategy or acquisition. If we experience difficulties, the anticipated benefits of a growth strategy or particular transaction may not be realized fully or at all, or may take longer to realize than expected.

We may not complete our development projects within the time frame or for the investment we anticipate, or at all, and the anticipated benefits of the new facilities may not be fully realized.

Developing a new location generally may be more risky than buying an existing operating location. Any development projects we plan could be delayed or not completed or could require a greater investment of capital or management time, or both, than we expect. Additionally, if we design, plan, permit or construct a project but do not complete it, we may incur substantial costs without realizing any expected benefits. Also, the facilities we construct may not generate the financial returns we anticipate.

Risks Arising from Certain of Our Relationships and Our Organization and Structure

Our agreements and relationships with HPT, our Managing Director, RMR and others related to them may create conflicts of interest, or the appearance of such conflicts, and may restrict our ability to grow our business.

We have significant commercial and other relationships with HPT, our Managing Director, The RMR Group LLC, or RMR, and others related to them, including:

In an agreement with HPT entered in 2007 in connection with our spin off from HPT and in our HPT Leases, we granted HPT a right of first refusal to purchase, lease, mortgage or otherwise finance any interest we own in a travel center before we sell, lease, mortgage or otherwise finance that travel center with another party. Under the 2007 agreement, we also granted HPT and other entities to which RMR provides management services a right of first refusal to acquire or finance any real estate of the types in which they invest before we do. Additionally, under the HPT Leases, without the consent of HPT, we generally cannot own, franchise, finance, operate, lease or manage any travel center or similar property within 75 miles in either direction along the primary interstate on which a travel center owned by HPT is located. These rights of first refusal and noncompetition provisions could limit our ability to purchase or finance our properties or properties we may wish to invest in or acquire in the future. Also, under the 2007 agreement we agreed not to take any action that might reasonably be expected to have a material adverse impact on HPT's ability to qualify as a real estate investment trust, or REIT. For more information regarding our transactions, and leases with HPT, see Note 7 and Note 12 to the Notes to Consolidated Financial Statements included in Item 15 of this Annual Report.

These relationships could create, or appear to create, conflicts of interest with respect to matters involving us, HPT, our Managing Director, RMR and others related to them. As a result of these relationships, our leases with HPT, management agreement with RMR and other transactions with HPT, our Managing Director, RMR and others related to them were not negotiated on an arm's length basis between unrelated parties, and therefore the terms thereof may not be as favorable to us as they would have been if they were negotiated on an arm's length basis between unrelated parties. In the past, in particular following periods of volatility in the overall market or declines in the market price of a company's securities, shareholder litigation, dissident shareholder director nominations and dissident shareholder proposals have often been instituted against companies alleging conflicts of interest in business dealings with affiliated and related persons and entities. These activities, if instituted against us, and the existence of conflicts of interest or the appearance of conflicts of interest, could result in substantial costs and diversion of our management's attention and could have a material adverse impact on our reputation, business and the market price of our common shares and other securities.

The substantial majority of the travel centers that we operate are owned by HPT and our business is substantially dependent on our relationship with HPT. In addition, we have significant commercial arrangements with RMR and we are dependent on those arrangements in operating our business.

Of the 256 travel centers we operate, 199 , or 78%, are owned by HPT and, as a result, our business is substantially dependent on our relationship with HPT. We lease these travel centers pursuant to five long term leases with HPT. HPT may terminate our leases in certain circumstances, including if HPT does not receive minimum annual rent on the subject properties or for certain other events of default. Our business is substantially dependent upon our continued relationship with HPT. The loss of our leases with HPT, or a material change to their terms, could have a material adverse effect on our business, financial condition or results of operations.

Additionally, we are party to a business management agreement with RMR whereby RMR assists us with various aspects of our business. As a result, we are dependent on our arrangements with RMR in operating our business and any adverse developments at RMR or in those arrangements could have a material adverse effect on our business and our ability to conduct our operations.

Ownership limitations and certain other provisions in our limited liability company agreement, bylaws and certain material agreements may deter, delay or prevent a change in our control or unsolicited acquisition proposals.

Our limited liability company agreement, or our LLC agreement, and bylaws contain provisions that prohibit any shareholder from owning more than 9.8% and 5%, respectively, of the number or value of any class or series of our outstanding shares. The 9.8% ownership limitation in our LLC agreement is consistent with our contractual obligations with HPT to not take actions that may conflict with HPT's status as a REIT under the Code. The 5% ownership limitation in our bylaws is intended to help us preserve the tax treatment of our tax credit carryforwards, net operating losses and other tax benefits. We also believe these provisions promote good orderly governance. These provisions inhibit acquisitions of a significant stake in us and may deter, delay or prevent a change in our control or unsolicited acquisition proposals that a shareholder may consider favorable.

Other provisions contained in our LLC agreement and bylaws may also inhibit acquisitions of a significant stake in us and deter, delay or prevent a change in control of us or unsolicited acquisition proposals that a shareholder may consider favorable, including, for example, provisions relating to:

In addition, the HPT Leases, our business management agreement with RMR and our credit agreement for our $200.0 million secured revolving credit facility, or our Credit Facility, each provide that our rights and benefits under those agreements may be terminated in the event that anyone acquires more than 9.8% of our shares or we experience some other change in control, as defined in those agreements, without the consent of HPT, RMR or the lenders under the Credit Facility, respectively, and that pursuant to our shareholders agreement with respect to AIC, AIC and the other shareholders of AIC may have rights to acquire our interests in AIC if such an acquisition occurs or if we experience some other change in control. In addition, our obligation to repay deferred rent then outstanding under our amended leases with HPT may be accelerated if, among other things, a Director not nominated or appointed by the then members of our Board of Directors is elected to our Board of Directors or if our shareholders adopt a proposal (other than a precatory proposal) not recommended for adoption by the then members of our Board of Directors. For these reasons, among others, our shareholders may be unable to realize a change in control premium for securities they own or otherwise effect a change of our policies or a change of our control.

The licenses, permits and related approvals for our operations may restrict ownership of us, or prevent or delay any change in control of us.

We have travel center locations in Illinois, Louisiana, Montana and Nevada which include gaming operations. As a result, we and our subsidiaries involved in these operations are subject to gaming regulations in those states. Under state gaming regulations, which can vary by jurisdiction:

As an owner of AIC, we are licensed and approved as an insurance holding company; and any shareholder who owns or controls 10% or more of our securities or anyone who wishes to solicit proxies for election of, or to serve as, one of our Directors or for another proposal of business not approved by our Board of Directors may be required to receive pre-clearance from the relevant insurance regulators.

The gaming and insurance regulations to which we are subject may discourage or prevent investors from nominating persons to serve as our Directors, from purchasing our securities, from attempting to acquire control of us or otherwise implementing changes that they consider beneficial.

Our rights and the rights of our shareholders to take action against our Directors, officers, HPT and RMR are limited.

Our LLC agreement eliminates the personal liability of each of our Directors to us and our shareholders for monetary damages for breach of fiduciary duty as our Director, except for a breach of the Director's duty of loyalty to us or our shareholders as modified by our LLC agreement, for acts or omissions not in good faith or which involved intentional misconduct or a knowing violation of law, or for any transaction from which the Director derived an improper personal benefit. Our LLC agreement also provides that our Directors and officers, HPT, RMR, and the respective trustees, directors and officers of HPT and RMR shall not be liable for monetary damages to us or our shareholders for losses sustained or liabilities incurred as a result of any act or omission by any of them unless there has been a final, nonappealable judgment entered by a court determining that such person or entity acted in bad faith or engaged in fraud, willful misconduct or, in the case of a criminal matter, acted with knowledge that his, her or its conduct was unlawful.

Our LLC agreement also generally requires us to indemnify, to the fullest extent permitted by law, our present and former Directors and officers, HPT, RMR, and the respective directors and officers of HPT and RMR for losses they may incur arising from claims or actions in which any of them may be involved in connection with any act or omission by such person or entity in good faith on behalf of or with respect to us. We also have similar obligations to our Directors and officers under individual indemnification agreements with such persons. In addition, we may be obligated to pay or reimburse the expenses incurred by our present and former Directors and officers, HPT, RMR, and the respective directors and officers of HPT and RMR without requiring a preliminary determination of their ultimate entitlement to indemnification. As a result, we and our shareholders may have more limited rights against our present and former Directors and officers, HPT, RMR, and the respective directors, trustees and officers of HPT and RMR than might otherwise exist absent the provisions in our LLC agreement and our indemnification agreements or that might exist with other companies, which could limit our shareholders' recourse in the event of actions not in our shareholders' best interest.

Disputes with HPT and RMR and shareholder litigation against us or our Directors and officers may be referred to binding arbitration proceedings.

Our contracts with HPT and RMR provide that any dispute arising under those contracts may be referred to binding arbitration proceedings. Similarly, our LLC agreement and bylaws provide that certain actions by our shareholders against us or against our Directors and officers, other than disputes or any portion thereof, regarding the meaning, interpretation or validity of any provision of our LLC agreement and bylaws may be referred to binding arbitration proceedings. As a result, we and our shareholders would not be able to pursue litigation in courts against HPT, RMR or our Directors and officers for disputes referred to arbitration in accordance with our LLC agreement and bylaws. In addition, the ability to collect attorney's fees or other damages may be limited in the arbitration proceedings, which may discourage attorneys from agreeing to represent parties wishing to commence such a proceeding.

We may experience losses from our business dealings with AIC.

We, HPT, and five other companies to which RMR provides management services each own 14.3% of AIC. We and those other AIC shareholders participate in a combined insurance program arranged and insured or reinsured in part by AIC and we periodically consider the possibilities for expanding our relationship with AIC to other types of insurance. Our principal reason for investing in AIC and for purchasing insurance in these programs is to seek to improve our financial results by obtaining improved insurance coverages at lower costs than may be otherwise available to us or by participating in any profits which we may realize as an owner of AIC. While we believe we have in the past benefitted from these arrangements, these beneficial financial results may not occur in the future, and we may need to invest additional capital in order to continue to pursue these results. AIC's business involves the risks typical of an insurance business, including the risk that it may not operate profitably. Accordingly, financial benefits from our business dealings with AIC may not be achieved in the future, and we may experience losses from these dealings.

Risks Related to Our Securities

Our shares have experienced significant price and trading volume volatility and may continue to do so.

Since we became a publicly traded company in January 2007, our shares have experienced significant share price and trading volatility, which may continue. The market price of our common shares has fluctuated and could fluctuate significantly in the future in response to various factors and events, including, but not limited to, the risks set out in this Annual Report, as well as:

In addition, in the past, following periods of volatility in the overall market and the market price of a company's securities, securities class action litigation has often been instituted against these companies. This litigation, if instituted against us, could result in substantial costs and a diversion of our management's attention and resources.

Investors may not benefit financially from investing in our Senior Notes.

The indenture under which the 2028 Senior Notes, the 2029 Senior Notes, and the 2030 Senior Notes, which we refer to collectively as the Senior Notes, were issued contains no financial covenants or other provisions that would afford the holders of the Senior Notes any substantial protection in the event we participate in a material transaction. In addition, the indenture does not limit the amount of indebtedness we may incur or our ability to pay dividends, make distributions or repurchase our common shares. Additionally, investors in our Senior Notes may be adversely affected as a result of the following:

Our Credit Facility imposes restrictive covenants on us, and a default under the agreements relating to our Credit Facility or under our indenture governing our Senior Notes could have a material adverse effect on our business and financial condition.

Our Credit Facility requires us and our subsidiaries, among other obligations, to maintain a specified financial ratio under certain circumstances and to satisfy certain financial tests. In addition, our Credit Facility restricts, among other things, our ability to incur debt and liens, make certain investments and pay dividends and other distributions including, under certain circumstances, payments on the Senior Notes. Under certain circumstances, we are required to seek permission from the lenders under our Credit Facility to engage in specified corporate actions.

Various risks, uncertainties and events beyond our control could affect our ability to comply with these covenants. Failure to comply with these covenants (or similar covenants contained in future financing agreements) could result in a default under our Credit Facility, indenture and other agreements containing cross default provisions, which, if not cured or waived, could have a material adverse effect on our business, financial condition and results of operations. A default could permit lenders or holders to accelerate the maturity of the debt under these agreements and to foreclose upon any collateral securing the debt and to terminate any commitments to lend. Under these circumstances, we might not have sufficient funds or other resources to satisfy all of our obligations, including our obligations under the Senior Notes. In addition, a default under our Credit Facility or indenture would also constitute a default under the HPT Leases due to cross default provisions in the HPT Leases. Further, the limitations imposed by financing agreements on our ability to incur additional debt and to take other actions might significantly impair our ability to obtain other financing. If our indebtedness were to be accelerated, our assets may not be sufficient to repay such indebtedness in full. In such circumstances, we could be forced into bankruptcy or liquidation and, as a result, investors could lose their investment in our securities.
