PART I

ITEM 1. Business and Properties

Overview

We are a growth‑oriented partnership formed by Landmark Dividend LLC (“Landmark” or “Sponsor”) to acquire, develop, own and manage a portfolio of real property interests and infrastructure assets that are leased to companies in the wireless communication, digital infrastructure, outdoor advertising and renewable power generation industries. The Partnership is a master limited partnership organized in the State of Delaware and has been publicly traded since its initial public offering on November 19, 2014 (the “IPO”). Our common units are listed on the NASDAQ Global Market under the symbol “LMRK”. The Partnership holds substantially all of its assets in a consolidated subsidiary, Landmark Infrastructure Inc., a Delaware corporation (“REIT Subsidiary”), which elected to be taxed as a real estate investment trust (“REIT”) under the Internal Revenue Code of 1986, as amended (the “Code”) commencing with its taxable year ending December 31, 2017. We intend to continue to own and operate substantially all of our assets through the REIT Subsidiary. Our legal structure substantially eliminates unrelated business taxable income allocated by the Partnership to tax-exempt investors, including individuals investing through tax-deferred accounts such as an individual retirement account, and we do not intend to generate state source income.

Our real property interests underlie our tenants’ infrastructure assets, which include freestanding cellular towers and rooftop wireless sites, powered shell spaces for data centers, billboards, wind turbines, solar arrays and development equipment. These assets are essential to the operations and profitability of our tenants. We seek to acquire real property interests subject to triple net or effectively triple net lease arrangements containing contractual rent increase clauses, or “rent escalators,” which we believe provide us with stable, predictable and growing cash flow. In certain instances, we own the infrastructure and lease the infrastructure to our tenants.

Our real property interests generally consist of a diversified portfolio of long‑term and perpetual easements, tenant lease assignments, fee simple properties and infrastructure assets located primarily in the United States and Canada. These real property interests and other infrastructure entitle us to receive rental payments from leases on our 1,986 tenant sites. Approximately 75% of our leased tenant sites are leased to large, publicly traded companies (or their affiliates) that have a national footprint and for our renewable power generation segment includes tenants with power purchase agreements with subsidiaries or affiliates of high credit rated utilities or high quality offtakers. These tenants, which we refer to as our “Tier 1” tenants, are comprised of AT&T Mobility, T‑Mobile and Verizon in the wireless carrier industry, Crown Castle, American Tower and SBA Communications in the cellular tower industry, Clear Channel Outdoor, Outfront Media and Lamar Advertising in the outdoor advertising industry, and Southern California Edison in the renewable power generation industry. Tenants in our digital infrastructure segment are excluded from “Tier 1” tenants. For our digital infrastructure industry, we focus on leasing our mission-critical data centers located in strategic markets in the United States to high-quality tenants.

We believe the terms of our tenant lease arrangements provide us with stable, predictable and growing cash flow. Substantially all of our tenant lease arrangements are triple net or effectively triple net, meaning that our tenants or the underlying property owners are contractually responsible for property‑level operating expenses, including maintenance capital expenditures, property taxes and insurance. For certain infrastructure assets, we incur ground rent obligations, maintenance expenditures, property taxes and insurance, some of which may be reimbursed by our tenants. As of December 31, 2020, 83% of our tenant leases (94% of rental revenue for the three months ended December 31, 2020) have contractual rent escalators, and some of our tenant leases contain revenue‑sharing provisions in addition to the base monthly or annual rental payments. In addition, we believe the physical infrastructure assets at our tenant sites are essential to the ongoing operations and profitability of our tenants. When combined with the challenges and costs of relocating these infrastructure assets and the key strategic locations of our real property interests, we expect continued high tenant retention and occupancy rates. As of December 31, 2020, we had a 94% occupancy rate, with 1,874 of our 1,986 total available tenant sites leased.

We benefit significantly from our relationship with Landmark, our Sponsor. Landmark, a private company formed in 2010, is one of the largest acquirers of real property interests underlying the operationally essential infrastructure assets in the wireless communication, digital infrastructure, outdoor advertising and renewable power generation industries. We believe Landmark’s asset acquisition and management platform will benefit us by providing us with acquisitions and development opportunities. Please read “Our Relationship with Landmark” and “Infrastructure Development”.

We conduct business through four reportable business segments: Wireless Communication, Digital Infrastructure, Outdoor Advertising and Renewable Power Generation. Our reportable segments are strategic business units that offer different products and services. They are commonly managed, as all of these businesses require similar marketing and business strategies. We evaluate our segments based on revenue because substantially all of our tenant lease arrangements are triple net or effectively triple net. We believe this measure provides investors with relevant and useful information because it is presented on an unlevered basis. See Notes to the Consolidated Financial Statements for additional information on our business segments.

Our Portfolio of Real Property Interests

Our portfolio of property interests consists primarily of (i) long‑term and perpetual easements combined with lease assignment contracts (which we refer to as our “lease assignments)” (ii) lease assignments without easements (iii) properties we own in fee simple and (iv) infrastructure we own and lease to our tenants. In connection with each real property interest, we have also acquired the rights to receive payment under pre‑existing ground leases from property owners, which we refer to as our “tenant leases.” Under our easements, property owners have granted us the right to use and lease the space occupied by our tenants, and when we have not been granted easements, we have acquired economic rights under lease assignments that are substantially similar to the economic rights granted under our easements, including the right to re‑lease the same space if the tenant lease expires or terminates.

The table below provides an overview of our portfolio of real property interests as of December 31, 2020.

(1) “Available Tenant Sites” means the number of individual sites that could be leased. For example, if we have an easement on a single rooftop, on which three different tenants can lease space from us, this would be counted as three “tenant sites,” and all three tenant sites would be at a single infrastructure location with the same address.

(2) Assumes the exercise of all remaining renewal options of tenant leases. Assuming no exercise of renewal options, the average remaining lease terms for our wireless communication, digital infrastructure, outdoor advertising, renewable power generation and total portfolio as of December 31, 2020 were 2.8, 9.9, 7.0, 16.8 and 4.7 years, respectively.

(3) Represents number of leased tenant sites divided by number of available tenant sites.

(4) Occupancy and average monthly effective rent per tenant site are shown only on an aggregate portfolio basis by industry.

(5) Represents total monthly revenue excluding the impact of amortization of above and below market lease intangibles divided by the number of leased tenant sites.

(6) Represents GAAP rental revenue recognized under existing tenant leases for the three months ended December 31, 2020. Excludes interest income on receivables.

(7) Fee simple ownership and perpetual easements are shown as having a term of 99 years for purposes of calculating the average remaining term.

(8) Reflects “springing lease agreements” whereby the cancellation or nonrenewal of a tenant lease entitles us to enter into a new ground lease with the property owner (up to the full property interest term) and a replacement tenant lease. The remaining lease assignment term is, therefore, equal to or longer than the remaining lease term. Also represents properties for which the “springing lease” feature has been exercised and has been replaced by a lease for the remaining lease term.

(9) Excluding perpetual ownership rights, the average remaining property interest term on our tenant sites is approximately 61 years.

Our real property interests entitle us to receive rental payments from tenant leases in the wireless communication, outdoor advertising and renewable power generation industries. The table below summarizes our Tier 1 tenants which comprised approximately 75% of our leased tenant sites as of December 31, 2020. Tenants in our digital infrastructure segment are excluded from the following table. For our digital infrastructure industry, we focus on leasing our mission-critical data centers located in strategic markets in the United States to high-quality tenants.

Our real property interests underlie a diverse range of tenant structures. We evaluate assets based on a variety of attributes, including, but not limited to, the marketability of the underlying title, the stability of the rental cash flow stream and opportunity for rent increases, tenant quality, the desirability of the structure’s geographic location, the importance of the structure to the ongoing operations and profitability of our tenants and the challenge and costs associated with tenants vacating sites. In certain instances, we lease a tenant site for our tenant’s base station and equipment, but not the tenant’s antenna array located on infrastructure owned by a third party. We refer to this type of arrangement as an “equipment only” lease. Within the wireless communication industry, our tenants’ structure types include rooftop sites, wireless towers (including monopoles, self-supporting towers, stealth towers and guyed towers), other structures (including, for example, water towers and church steeples or commercial properties) and equipment only sites. In the outdoor advertising industry, our tenants’ structure types include both static billboards and digital billboards. Our real property interests in the renewable power generation industry currently underlie wind turbines and solar arrays.

The table below presents an overview of the structures underlying our real property interests, as of December 31, 2020.

(1) “Available Tenant Sites” means the number of individual sites that could be leased. For example, if we have an easement on a single rooftop, on which three different tenants can lease space from us, this would be counted as three “tenant sites,” and all three tenant sites would be at a single infrastructure location with the same address.

(2) Fee simple ownership and perpetual easements are indicated as having a term of 99 years for purposes of calculating the average remaining term. Also includes “springing lease agreements” whereby the cancellation or nonrenewal of a tenant lease entitles us to enter into a new ground lease with the property owner (up to the full term) and a replacement tenant lease. The remaining lease assignment term is, therefore, in many cases, higher than the remaining tenant lease term.

(3) Assumes the exercise of all remaining renewal options. Assuming no exercise of renewal options, the average remaining lease terms for our wireless communication, digital infrastructure, outdoor advertising, renewable power generation and total portfolio as of December 31, 2020 were 2.8, 9.9, 7.0, 16.8 and 4.7 years, respectively.

(4) Represents GAAP rental revenue recognized under existing tenant leases for the three months ended December 31, 2020. Excludes interest income on receivables.

(5) In certain instances, we lease our tenant site for our tenant’s base station and equipment, but the tenant’s antenna array and related hardware are located on infrastructure owned by a third party. We refer to this type of arrangement as an “equipment only” lease. At 55 infrastructure locations, we have leased space for equipment together with other structures.

(6) Excluding perpetual ownership rights, the average remaining property interest term on our tenant sites is approximately 61 years.

We are geographically diversified with assets primarily located throughout the United States, and no single state accounted for more than 13% of our tenant sites as of December 31, 2020 and 25% of total revenue for the year ended December 31, 2020. Additionally, the majority of our wireless communication and outdoor advertising assets are located in major cities, significant intersections, and traffic arteries in the United States that benefit from high urban density, favorable demographic trends, strong traffic counts and strict zoning restrictions with legacy zoning rights (commonly referred to as “grandfather clauses.”) These attributes enhance the long‑term value of our real property interests, as our wireless communication and outdoor advertising tenants are focused on placing their assets in dense areas with large populations and along high‑traffic corridors. Additionally, local zoning regulations often restrict the construction of new cellular towers, rooftop wireless structures and outdoor advertising and billboard structures, creating barriers to entry and a supply shortage.

Our digital infrastructure assets are mission-critical, high-quality, network-neutral powered shell data centers, primarily supporting colocation and enterprise tenants, in strategic markets across the United States and Canada. The powered shell data centers are highly-specialized facilities that are expensive and require significant technical expertise to build and manage, creating high barriers to entry. Typically, these powered shells are data center properties whereby the landlord makes the initial capital investment required to complete an exterior structure with access to power and fiber optics, with tenants providing all additional capital required to build-out the interior and convert the asset into a fully operational data center. Tenant turnover is infrequent due to the significant upfront tenant investments into the property and the high cost and risk of potential disruption from relocating critical IT infrastructure. At expiration or termination of the lease, the equipment either remains at the property, free and clear of any debt, or the operator has the right to relocate the equipment but is typically left behind as it is not economical to relocate. We believe this leads to improved value of our assets and further increases the likelihood for continued high occupancy.

Approximately 70% and 80% of our tenant sites are located in Top‑50 and Top‑100 ranked Basic Trading Areas (“BTA”), respectively, including New York, Los Angeles and Chicago. We believe our locations in major metropolitan population centers are highly desirable for our tenants in the wireless communication and outdoor advertising industries seeking to reach a large customer base.

The table below summarizes our real property interests by BTA rank as of December 31, 2020.

Easements and Lease Assignments

In most locations, our tenant leases were acquired together with an easement granted by the property owner in favor of Landmark, granting us the rights to the tenant site occupied by the tenant under the lease. For our tenant sites that were not accompanied by an easement or purchased in fee, our lease assignments provide us with economic rights that are substantially similar to the economic rights granted under our easements, including the right to re‑lease the same space if the tenant lease expires or terminates. In limited circumstances, we lease the sites from property owners and then sub‑lease those spaces to our tenants.

The terms of our easements and lease assignments generally range from 15 years to 99 years with certain assets having perpetual easement terms. The average remaining term of our easements and lease assignments is approximately 70 years (assuming perpetual easements, which comprise approximately 33% of our total easements, have a term of 99 years). When we acquire an easement or lease assignment in connection with a property subject to a mortgage, we generally also enter into a non‑disturbance agreement with the mortgage lender in order to protect us against potential foreclosure on the property owner at the infrastructure location, which foreclosure could, absent a non‑disturbance agreement, extinguish our easement or lease assignment. In some instances where we obtain non‑disturbance agreements, we still remain subordinated to some indebtedness. As of December 31, 2020, approximately 18% of our tenant sites are not subject to non‑disturbance agreements or have not been otherwise recorded in local real estate records in senior positions to any mortgages.

Our easements and lease assignments strengthen and protect our real property interests in any given infrastructure location by allowing us to control the use of the tenant site after the expiration of the primary lease term (plus extension options) and to prevent a property owner from interfering with the operations of our tenants.

Additionally, we believe that our easements and lease assignments have been and will continue to be acquired and structured in a manner that mitigates additional risks in many ways, including the following:

• We record our easements and lease assignments in local real property records, giving constructive notice of our real property interest to all successor property owners and other parties of interest (such as future lenders).

• We perform a title search prior to the acquisition of the easement or lease assignment and obtain title insurance on the easement or lease assignment except where doing so would not be economic or otherwise feasible, and all material exceptions to title are typically addressed prior to purchase.

• Our possessory use rights to the underlying property mitigate our liability exposure, and we are typically indemnified by the property owners or our tenants for environmental liability, if any, relating to the property. In addition, general liability insurance is typically provided by our tenants.

9

• Our easements and lease assignments, together with our non‑disturbance agreements, generally protect our real property interest in case of a foreclosure against the property owner.

• The property owner is generally contractually responsible for their property‑level operating expenses, including maintenance capital expenditures, taxes and insurance. For certain infrastructure assets, we incur ground rent obligations, maintenance expenditures, property taxes and insurance, some of which may be reimbursed by our tenants.

Finally, in the event that one of our tenant leases expires without renewal or is terminated, all of our easements and substantially all of our lease assignments allow us to enter into a new lease of the same space for the same use. For some of our easement or lease assignments, if we do not enter into a new lease during the tenant replacement period (typically three to five years), in the case of an easement, the easement terminates and control of the space reverts back to the property owner, or in the case of a lease assignment, we forfeit our right to re‑lease the space.

In limited circumstances, we have granted a landowner the right to re‑acquire our real property interest at a purchase price which we believe makes us economically whole for the loss of an asset.

Fee Simple Properties

Our portfolio of real property interests includes 70 properties owned in fee simple. These properties have associated tenant leases in the wireless communication, digital infrastructure, outdoor advertising and renewable power generation industries. Generally, these property leases are leased to tenants under triple net or effectively triple net lease arrangements, meaning that our tenants are contractually responsible for property‑level operating expenses, including maintenance capital expenditures, taxes and insurance. For certain infrastructure assets, we incur maintenance expenditures, property taxes and insurance, some of which may be reimbursed by our tenants. For the year ended December 31, 2020, we received $17.0 million in rental revenue related to these properties, representing 29% of rental revenue.

(1) Remaining term of real property interest is based on the assumption that the site is not vacant for a period longer than our tenant replacement period. This assumption is not used in calculating the remaining tenant lease terms and is inapplicable to the remaining term of real property interest of our fee simple properties.

(2) “Leased Tenant Sites” means the number of individual sites that are leased. For example, if we have an easement on a single rooftop, on which three different tenants lease space from us, this would be counted as three “tenant sites,” and all three tenant sites would be at a single infrastructure location with the same address.

(3) Assumes the exercise of all remaining renewal options of tenant leases. Assuming no exercise of renewal options, the average remaining lease terms for our wireless communication, digital infrastructure, outdoor advertising, renewable power generation and total portfolio as of December 31, 2020 were 2.8, 9.9, 7.0, 16.8 and 4.7 years, respectively.

Other Assets

While we generate substantially all of our revenue from our ownership and leasing of real property interests, we also generate a small amount of revenue from other assets including financing arrangements. Additionally, certain lease arrangements of real property interests meet the definition of a financial asset and are included in investments in receivables in our financial statements. Our other assets also include arrangements with T‑Mobile whereby we purchased the right to retain a portion of a lease payment prior to passing the remainder to the property owner. These cash flow financing arrangements are accounted for as receivables in our financial statements.

Tenant Leases

The majority of our tenant leases were acquired from property owners, who assigned to us all of the property owner’s rights, title and interest in and pursuant to (but generally excluding obligations under) a pre‑existing lease between the property owner and a third‑party tenant, such as a wireless carrier, cellular tower operator, colocation provider, billboard owner, or renewable power producer. Generally, we do not assume all of the landlord’s obligations under the tenant lease, such as the obligation to provide quiet enjoyment of the property or to pay property taxes. These leases previously provided the property owner with a stream of rental payments, typically paid monthly or annually, and were assigned to us in exchange for an up‑front lump sum payment.

Generally, our leased tenant sites are subject to triple net or effectively triple net lease arrangements, meaning that our tenants or the underlying property owners are contractually responsible for property‑level operating expenses, including maintenance capital expenditures, taxes and insurance. For certain infrastructure assets, we incur ground rent obligations, maintenance expenditures, property taxes and insurance, some of which may be reimbursed by our tenants. For this reason, we expect to have a slight increase in operating expenses relating to our infrastructure assets. For the years ended December 31, 2020, 2019 and 2018, our property operating and maintenance expenses were approximately 3%, 3%, and 2% of revenue, respectively.

We believe our triple net and effectively triple net lease arrangements support a stable, consistent and predictable cash flow profile due to the following characteristics attributable primarily to our non infrastructure assets:

• no equipment maintenance costs or obligations (tenant is responsible for all maintenance and Landmark’s role is limited to billing, collections and managing the ground lease);

• no property‑level maintenance capital expenditures; and

• no property tax or insurance obligations (tenant or property owner is responsible for these costs).

Our tenant leases are typically structured with five‑year, ten‑year or twenty-year initial terms and four additional, successive five‑year renewal terms. The average remaining lease term of our tenant leases is 20 years including renewal terms, and the average remaining lease term of our tenant leases is 5 years excluding renewal terms. Our tenant leases produce an average of approximately $3,000 per month in GAAP rental payments, but can range from as low as $38 per month to as much as $0.25 million per month. In addition, most of our tenant leases include built‑in rent escalators, which are typically structured as fixed amount increases, fixed percentage increases, or CPI‑based increases and increase rent annually or on the renewal of the lease term. Furthermore, 419 of our tenant leases, primarily in the outdoor advertising industry, contain revenue sharing provisions. As of December 31, 2020, 83% of our tenant leases contained contractual rent escalators, 77% of which were fixed‑rate (with an average annual escalation rate of approximately 2.4%) and 6% of which were tied to CPI. For the three months ended December 31, 2020, 94% of quarterly rental revenue contained rent escalators, 91% of which were fixed-rate and 3% of which were tied to CPI.

Though our tenant leases are typically structured as long‑term leases with fixed rents and rent escalators, our wireless communication and outdoor advertising tenants generally may cancel their leases upon 30 to 180 days’ notice. However, occupancy rates under our tenant leases have historically been very high. Our digital infrastructure and renewable power generation tenants generally have non-cancellable leases. As of December 31, 2020, we had 1,874 tenant sites leased and 112 tenant sites available for lease. We believe the infrastructure improvements and operations of the tenant assets located on our real property interests are essential to the ongoing operations and profitability of our tenants. We believe that by focusing on high‑quality real property interests we increase the likelihood that our tenants will renew their leases upon expiration. We believe that the importance of these assets, combined with the challenges and costs of relocating these infrastructure improvements, make it likely that we will continue to enjoy high tenant retention and occupancy rates. We believe the location of our available sites, the importance of these infrastructure assets, wireless network densification and difficulties in site acquisition provide additional collocation and releasing opportunities.

We monitor tenant credit quality on an ongoing basis by reviewing, where available, the publicly filed financial reports, press releases and other publicly available industry information regarding the parent entities of our tenants. In addition, we monitor payment history data for all of our tenants. We are otherwise generally not entitled to financial results or other credit‑related data from our tenants.

Our Tenants

Our tenants operate in the wireless communication, outdoor advertising and renewable power generation industries. They are generally large, publicly traded companies (or their affiliates) with a national footprint. Approximately 83% of our rental revenue for the three months ended December 31, 2020 was derived from our Tier 1 tenants. Our tenants in the digital infrastructure industry generally consist of large companies that provide colocation services or enterprises using mission-critical powered shell data centers located in strategic markets in the United States to support their operations. Tenant turnover is infrequent due to the significant upfront tenant investments into the property and the high cost and risk of potential disruption from relocating critical IT infrastructure. In the course of evaluating acquisition opportunities, we assess the desirability of an infrastructure location to our tenants and factors impacting demand of their customers.

Wireless Communication

Our wireless communication tenants consist primarily of wireless carriers (and their affiliates), such as T‑Mobile, AT&T Mobility and Verizon, and tower companies (and their affiliates) such as Crown Castle, American Tower and SBA Communications. These tenants generally lease from us space underlying their cellular towers, antennas, radios and other electronic communications equipment.

We have strong renewal rates among our wireless communication tenants. We believe that this trend will continue because the decommissioning and repositioning of a current site in an existing carrier’s network is expensive and often requires the reconfiguration of several other sites within the carrier’s network, which may impact the carrier’s network quality and coverage. In addition, zoning restrictions may significantly delay, hinder or prevent entirely the construction of new sites. Construction, decommissioning and relocation of a current site may also require the carrier to obtain additional governmental permits, further increasing the cost of non‑renewal of a lease with us. In addition, as thousands of new tenant sites are constructed each year, many of these sites will be co‑located on towers and other structures located on our real property interests. We believe each of these attributes helps us achieve stable, consistent and predictable cash flow, which will lead to consistent distributions for our unitholders.

Rental rates associated with wireless communication assets are tied to various factors, including:

• infrastructure location;

• amount, type and function of the tenant’s equipment on the infrastructure location;

14

• ground space necessary for the tenant’s base station and other infrastructure required for the transmission and reception of signal;

• remaining capacity at the infrastructure location;

• shared back‑up power availability;

• type of structure (e.g., stealth tower, rooftop, water tower); and

• location of the customer’s antennas on the infrastructure location.

Digital Infrastructure

Our digital infrastructure assets are mission-critical, high-quality, network-neutral powered shell data centers, primarily supporting colocation and enterprise tenants, in strategic markets across the United States and Canada. These tenants generally consist of large companies. We typically invest in the powered shell component of a data center, which includes the land and exterior structure of the building, and our tenants provide all additional capital required to build-out the interior and convert the asset into a fully operational data center. In a powered shell, the equipment at the property is owned by the data center operator through the life of the lease; however, at expiration or termination of the lease the data center operator either relocates the equipment or the equipment remains at the property and is required to be free and clear of any debt.

Data centers are highly specialized facilities that provide space, power, and cooling for network infrastructure and allow for the storage, sharing and management of data. Data centers are expensive and require significant technical expertise to build and manage, creating high barriers to entry. Tenant turnover is infrequent due to the significant upfront tenant investments into the property and the high cost and risk of potential disruption from relocating critical IT infrastructure. Our types of data centers include the following:

• Enterprise - An enterprise data center is a facility that is typically operated for the company it supports. The data center is typically managed by internal staff or outsourced to a third-party via a facility management contract. Driven by infrastructure demand outpacing supply, a recent trend has emerged in the data center market where enterprises divest of their data center assets, while still maintaining operations, by engaging in sale-leaseback opportunities with data center buyers. This partnership between buyer and seller/tenant allows for the enterprise to focus on and reinvest in their core business.

• Wholesale colocation - Wholesale colocation data centers typically cater to larger data center tenants and, therefore, have fewer tenants in each location. Leases often tend to be longer on average (5 to 10 years) and are usually greater than half a Megawatt (MW). Tenants typically lease entire suites or buildings at wholesale data centers, whereas colocation tenants typically lease racks or cabinets in a multitenant suite.

• Colocation - Consists of one data center with multiple customers (often 20 and more) in a single location. Colocation generally caters to smaller data center needs with leases (or license agreements) that tend to be shorter on average (<5 years) and power consumption usually for significantly less than half a MW.

We intend to focus on acquiring high-quality, network-neutral powered shell data centers, primarily supporting colocation and enterprise tenants, in strategic markets across the United States and Canada. Additionally, we expect the assets to have an anchor tenant in place for whom the data center is critically important for its continued operations as well as leases that are structured on a long-term, net basis and contain contractual rent escalators.  

Data center assets have high tenant retention rates due to the significant upfront investments made by the tenants and the high cost and risk of disruption associated with relocating critical IT infrastructure.

Rental rates associated with digital infrastructure assets are tied to various factors, including:

• Infrastructure location;

• Square footage;

• Interconnectivity of telecommunication infrastructure;

• Electrical power density;

• Value of underlying real estate; and

• Type of data center (e.g., enterprise, colocation).

Outdoor Advertising

Our outdoor advertising tenants include companies (and their affiliates) that own and manage billboards, such as Clear Channel Outdoor, Outfront Media and Lamar Advertising. These tenants generally lease space from us underlying billboards, typically along highly trafficked freeways and intersections.

15

We have strong renewal rates among our outdoor advertising tenants. We believe that this trend will continue because billboards are the primary revenue generating assets of our outdoor advertising tenants. The outdoor advertising market is characterized by strict local regulations and zoning laws, which have made it extremely difficult to erect new billboards in many markets. Additionally, many existing sites are “non‑conforming” with regard to current zoning standards but have been “grandfathered” in (and therefore not required to be removed) as they have been in place for long periods of time prior to the change in zoning standards. As such, there is typically a very high rate of lease renewal among our outdoor advertising tenants, and we believe that these renewals will continue to provide stable, growing revenue.

Rental rates associated with outdoor advertising assets are tied to various factors, including:

• infrastructure location;

• illumination for night‑time visibility;

• display and face size;

• roadside position with respect to traffic flow;

• angle to the road for maximum visibility;

• street type (e.g., highway, interstate, cross‑section);

• traffic count;

• viewer traffic metrics;

• type of display (e.g., static face, digital billboard, tri‑vision); and

• height above ground level.

Renewable Power Generation

Our renewable power generation tenants currently lease space from us underlying wind turbines or solar arrays. Our renewable power generation tenants’ counterparties consist primarily of subsidiaries or affiliates of credit rated utilities or high quality offtakers, such as Southern California Edison.

We believe we will have strong renewal rates among our renewable power generation tenants. The renewable power generation industry is characterized by long development periods and projects of significant scale, typically requiring large capital commitments and several years of due diligence by the project operator to ensure suitability of the project location prior to commencement of project construction. In the case of wind turbines, a three‑year wind study is typically completed by the developer to study the wind patterns at the proposed project location. Similarly, prior to the construction of a commercial solar project, the developer will typically complete a review of historical weather patterns to evaluate the amount of uninterrupted access to sunlight at the project location. Developers must also consider accessibility to transmission infrastructure and power connects when selecting a project site, significantly restricting the ability to relocate a renewable power project.

We intend to target renewable power projects that have been developed within the last five years, have the most current and efficient equipment with the longest useful life. When seeking real property interests in this industry, we will seek assets that have a power purchase agreement in place between the owner of the project and a utility or other high credit quality offtaker. The power purchase agreement defines the terms between the counterparties and sets the sales price of the power generated for an extended period of time, typically twenty years. We believe these attributes lead to a very high rate of lease renewal and will help us achieve stable cash flow from the renewable power generation industry.

Rental rates associated with renewable power generation assets are tied to various factors, including:

• Infrastructure location;

• Ground space necessary for the project;

• Interconnecting power grid infrastructure;

• Proximity and access to transmission lines;

• Value of underlying real estate;

• Project profit (typical rental rates represent a low percentage of the project estimated earnings);

• Location’s geographical and meteorological characteristics which expect to yield the highest energy production; and

• Competition by multiple developers for the same property.

Our Relationship with Landmark

One of our principal strengths and greatest competitive advantages is our relationship with Landmark. Landmark is one of the largest and most active acquirers of real property interests underlying infrastructure assets in the wireless communication, digital infrastructure, outdoor advertising and renewable power generation industries. Landmark, headquartered in Los Angeles, California, has approximately 182 employees and has offices and acquisition and development team members who work across the United States, Canada and Australia. Landmark has stated that it intends to continue to identify additional acquisitions and development opportunities.

As of December 31, 2020, Landmark and affiliates owns our general partner, all of the incentive distribution rights and a 13.4% limited partner interest in us. Given its substantial cash investment and significant ownership in us, we believe Landmark will promote and support the successful execution of our business strategies. On January 30, 2019, the Partnership amended the Omnibus Agreement with Landmark to extend the general and administrative expense reimbursement to the earlier to occur of: (i) the date on which our revenue for the immediately preceding four consecutive fiscal quarters exceeded $120 million and (ii) November 19, 2021. While we believe Landmark is incentivized to support us, there are no restrictions on the ability of Landmark or its affiliates, including new private funds that Landmark may form, to compete with us, including for the acquisition of future real property interests. Please read “Risk Factors – Risks Related to Our Business – If we are unable to make accretive acquisitions of real property interests or pursue new development opportunities, our growth could be limited” and “Conflicts of Interest.”

Drop-down Acquisitions

During the year ended December 31, 2018, the Partnership completed one drop-down acquisition of 127 tenant sites and related real property interests, from the Sponsor and affiliates in exchange for total consideration of $59.9 million (the “Drop-down Acquisitions” or “Drop-down Assets”). There were no drop-down acquisitions during the years ended December 31, 2020 and 2019.

Landmark’s Acquisition Platform

Landmark’s senior management team has an established track record and deep domain expertise across all aspects of the business including sourcing, underwriting, acquisition, financing and asset management.

The real property interests Landmark seeks to acquire generally range in value from $0.1 million to $0.5 million for wireless communication and outdoor advertising and $5 million to $100 million for digital infrastructure and renewable power generation. As a result, Landmark must assemble large pools of assets to achieve portfolio critical mass and diversification. To accomplish this, specialized teams within Landmark use custom information technology systems and processes developed over the past decade to manage workflow while providing management with the ability to monitor and direct activity. Through these proprietary processes, Landmark efficiently evaluates assets to ensure they meet Landmark’s stringent underwriting criteria. Landmark believes that the small individual asset size, together with the expertise and discipline required to close high acquisition volumes, creates a significant barrier to entry for prospective competitors. We expect to benefit greatly from Landmark’s acquisition platform, which we believe will continue to facilitate the acquisition of attractive assets for our business.

Asset Life Cycle through the Acquisition Platform

The Landmark process has been specifically designed to be as seamless and efficient for the owner (and, in doing so, more efficient for Landmark as well). Landmark has customized its processes and documentation for its specific business, emphasizing customer interaction and delivering a high‑quality transaction experience. In addition, documentation is requested from the property owner in a concise, straightforward manner and expectations and timing are discussed with the owner, making the transaction process transparent to the property owner. In this way, the property owner is engaged, there are limited surprises and the closing process is more of a joint exercise between Landmark and the property owner, resulting in a better customer experience.

Landmark’s high volume, small balance real property acquisition and asset management platform has four primary phases which include: (1) Lead Generation; (2) Origination; (3) Underwriting and Closing; and (4) Asset Management.

Lead Generation

Landmark developed a proprietary lead‑generation system that expedites the identification of small balance real property interests in fragmented real property ownership industries. This system, used by its employees to identify asset prospects, facilitates the aggregation of directly‑sourced field data. Once an infrastructure location prospect has been identified, Landmark’s team leverages a variety of proven data and technology resources and strategies to obtain preliminary contact information for the property owner, referred to as a “lead”. Leads are qualified by a dedicated team that validates data directly with the owner of the infrastructure location. Once the property owner’s address and contact information is confirmed, an account is created and an appointment is arranged.

17

Origination

The origination process begins with a meeting between a Landmark acquisition professional and the property owner. Landmark’s acquisition professionals engage in meetings with property owners to establish a relationship, discuss the owner’s needs and objectives, and educate the owner on the value of Landmark’s proposed transaction. During these meetings, acquisition professionals evaluate the appropriateness of Landmark’s proposed transaction for the property owner and their interest level in selling their real property interest. Once Landmark obtains a copy of the lease from the property owner, relevant data is input into Landmark’s proprietary asset evaluation system to generate an acquisition agreement. The acquisition agreement terms are negotiated with the property owner and, upon acceptance of the agreement, Landmark uploads the executed agreement and necessary documentation to its proprietary technology platform for further diligence by the dedicated underwriting and closing team.

Underwriting and Closing

After Landmark’s proposal has been accepted by the property owner and an acquisition agreement has been executed, the transaction is moved to Landmark’s dedicated underwriting and closing team. The account enters a comprehensive due diligence process to ensure consistent quality across Landmark’s portfolio of asset acquisitions. Curative measures are taken to clear title on the real property interest (for example, an outstanding creditor’s lien) simultaneous with the underwriting and due diligence process. Given its considerable experience, depth of resources, and proven processes, Landmark is able to perform a comprehensive and efficient underwriting of the risk and value assessment on its high‑volume acquisition pipeline. We believe this is one of Landmark’s greatest strengths and competitive advantages and is driven by (i) Landmark’s extensive database of comparable transactions and leases, and (ii) its thorough understanding of applicable underwriting factors (such as which intersections or highways tend to have the most traffic, applicable zoning regulations and the availability of nearby wireless or advertising sites). In the underwriting stage, Landmark reviews various transaction materials and documents for compliance with Landmark’s underwriting criteria, including, but not limited to, the following:

• current industry macro and micro risks;

• tenant counterparty risk;

• lease economics;

• lease terms;

• “seasoning,” or whether the property has a proven track record of tenant lease payments, and the details of that track record;

• evaluation of real estate and infrastructure based in part on site visits and surveys;

• site demographics;

• competitive landscape analysis; and

• rent analysis based on Landmark’s proprietary database of comparative rents in the target area.

Once a transaction is deemed to meet Landmark’s due diligence and underwriting standards, it proceeds to Landmark’s investment committee for approval of the acquisition. Pending approval, legal closing documents are prepared, executed and delivered. Due to its streamlined proprietary acquisition process, Landmark has the ability to quickly close acquisitions. We expect to continue to benefit from Landmark’s high acquisition volumes and more efficient, scalable processes.

Asset Management

After funding, tenants are notified of the acquisition and notarized payment re‑direction letters are sent advising the tenant to redirect rental payments to Landmark. All post‑closing items are revisited, the lease data is re‑verified and moved to Landmark’s asset management, where compliance is monitored on an ongoing basis. The tenant management phase includes collections, tenant payment conversion, tenant relations, and tenant contact management. The asset management phase also includes the negotiation of lease renewals, modifications, cancellations, reductions, document and consent requests, landlord and tenant complaints and new leasing of available tenant sites. In certain instances, we may utilize a third-party asset management service provider.

Direct Third-Party Acquisitions

The Partnership completed direct third-party acquisitions of real property interests in the wireless communication, digital infrastructure, outdoor advertising and renewable power generation industries in domestic and international locations. During the years ended December 31, 2020 and 2019, the Partnership acquired 15 tenant sites and 146 tenant sites from third parties for total consideration of $144.2 million and $52 million, respectively. See Note 3, Acquisitions, to the Consolidated Financial Statements for additional information.

18

Unconsolidated Joint Venture

On September 24, 2018, the Partnership completed the formation of an unconsolidated joint venture. The Partnership contributed 545 tenant site assets to the unconsolidated joint venture that secured the Partnership’s $125.4 million Series 2018-1 secured notes, in exchange for a 50.01% membership interest in the unconsolidated JV and $65.5 million in cash. The Partnership does not control the unconsolidated joint venture and therefore, accounts for its investment in the unconsolidated joint venture using the equity method of accounting prospectively upon formation of the unconsolidated joint venture. For the years ended December 31, 2020 and 2019, the joint venture generated rental revenue of $14.4 million and $14.2 million, respectively, and from September 24, 2018 through December 31, 2018, the joint venture generated rental revenue of $3.7 million. See Note 8, Investment in Unconsolidated Joint Venture, to the Consolidated Financial Statements for additional information.

Infrastructure Development

During 2017, the Partnership started developing an ecosystem of technologies that provides smart enabled infrastructure including stealth towers and digital outdoor advertising kiosks across North America. Stealth towers are self-contained, neutral-host towers designed for wireless carrier and other wireless operator collocation. The stealth towers are designed for macro, mini macro and small cell deployments and will support Internet of Things (IoT), carrier densification needs, private LTE networks and other wireless solutions.

During the fourth quarter of fiscal year 2018, the Partnership entered into an agreement with Dallas Area Rapid Transit (“DART”) to develop a smart media and communications platform which will include the deployment of content-rich kiosks and the Partnership’s smart enabled infrastructure ecosystem solution on strategic high-traffic DART locations.    

As of December 31, 2020 and 2019, the Partnership’s $44.8 million and $49.1 million, respectively, of construction in progress balance primarily related to these development projects. During the year ended December 31, 2020, the Partnership deployed two stealth towers, 112 DART kiosks and placed in service other assets for a total of $16.2 million. During the years ended December 31, 2019 and 2018, the Partnership deployed nine and four infrastructure sites totaling $1.0 million and $1.5 million, respectively. As we deploy these infrastructure assets, we may incur additional operating expenses associated with ground lease payments and other operating expenses to maintain our infrastructure assets. Additionally, the Partnership may pursue further development opportunities in the future.

Regulation

Environmental Matters

Laws and regulations governing the discharge of materials into the environment or otherwise relating to the protection of the environment are applicable to our business and operations, and also to the businesses and operations of our lessees, property owners and other surface owners or operators. Federal, state and local government agencies issue regulations that often require difficult and costly compliance measures that carry substantial administrative, civil and criminal penalties and that may result in injunctive obligations for non‑compliance. These laws and regulations often require permits before operations commence, restrict the types, quantities and concentrations of various substances that can be released into the environment, require remediation of released substances, and limit or prohibit construction or operations on certain lands (e.g. wetlands). We do not conduct any operations on our properties, but we or our tenants may maintain small quantities of materials that, if released, would be subject to certain environmental laws. Similarly, our property owners, lessees and other surface interest owners may have liability or responsibility under these laws which could have an indirect impact on our business. These laws include but are not limited to the federal Resource Conservation and Recovery Act (“RCRA”), and comparable state statutes and regulations promulgated thereunder (which impose requirements on the generation, transportation, treatment, storage, disposal and cleanup of hazardous and non‑hazardous wastes) and the Comprehensive Environmental Response, Compensation and Liability Act (“CERCLA”), and analogous state laws which generally impose liability, without regard to fault or legality of the original conduct, on classes of persons who are considered to be responsible for the release of hazardous substances into the environment, including the current and former owners or operators of a site. It is not uncommon for neighboring property owners and other third‑parties to file claims for personal injury and property damage allegedly caused by the hazardous substances released into the environment. Therefore, governmental agencies or third parties may seek to hold us, our lessees, property owners and other surface interest owners responsible under CERCLA and comparable state statutes for all or part of the costs to cleanup sites at which hazardous substances have been released. Our agreements with our lessees, property owners and other surface owners generally include environmental representations, warranties, and indemnities to minimize the extent to which we may be financially responsible for liabilities arising under these laws.

Seasonality

We generally receive fixed rental payments under our tenant leases that are typically paid on a monthly basis, and we expect to experience some seasonal effect on our cash flow due to rents paid annually. Additionally, we have revenue sharing provisions under a portion of our tenant leases, which may result in some seasonal effect on our cash flow.

19

Competition

We face competition in the acquisition, development and leasing of our assets in each of our target industries. Some of the competitors are larger than us and include public entities with greater access to capital and scale of operations than us. In addition, Landmark and its affiliates will compete with us for acquisitions, development and the leasing of real property interests. Please read “Risk Factors – Risks Inherent in an Investment in Us – Landmark may compete with us, and Landmark, as owner of our general partner, will decide when, if and how we complete acquisitions.”

In the acquisition of real property interests underlying our tenants’ infrastructure, our principal competitors include our tenants and private independent acquirers focused on individual industries. In the wireless communication industry, the principal competitors include tower companies such as American Tower, Crown Castle International and SBA Communications and private independent acquirers such as Melody Wireless Infrastructure. In the outdoor advertising industry, the outdoor advertising tenants (such as Lamar) and smaller regional private investors would be our principal competitor. In the renewable power generation industry, the principal competitor is Hannon Armstrong Sustainable Infrastructure Capital, Inc. In the digital infrastructure industry, the principal competitors are IPI Partners, LLC, GI Partners, Lincoln Property Company, T5 Data Centers and Legacy Investing, LLC. We believe the most significant factors affecting the competitive environment in the acquisition of real property interest underlying our tenant’s infrastructure include the relationship with the property owner, price offered, structure and terms of the acquisition, time to closing and surety of closing.

In the leasing of real property interests in the wireless communication industry, our principal competitors include our tenants, private property owners, REITs (including the tower companies) and various governmental agencies. In the wireless communication industry, our principal competitors include wireless carriers that own their own tower networks, tower companies such as American Tower Corporation, Crown Castle and SBA Communications, private independent owners of portfolios of real property interest such as Melody Wireless Infrastructure, real estate owners, REITs, utilities, municipalities and other companies that provide structures upon which wireless communication equipment may be installed. In the outdoor advertising industry, the principal competitors include private real estate owners, REITs and municipalities. In the renewable power generation industry, the principal competitors include private real estate owners, REITs and municipalities. In the digital infrastructure industry, the principal competitor are IPI Partners, LLC, GI Partners, Lincoln Property Company, T5 Data Centers and Legacy Investing, LLC. We believe the most significant factors affecting the competitive environment in the leasing of real property interest underlying our tenant’s infrastructure include site location and capacity, quality of service, density within a geographic market and, to a lesser extent, price.

Employees

We are managed and operated by the board of directors and executive officers of Landmark Infrastructure Partners GP LLC, our general partner. Neither we nor our subsidiaries have any employees. Our general partner has the sole responsibility for providing the employees and other personnel necessary to conduct our operations. All of the employees that conduct our business are employed by affiliates of our general partner. As of December 31, 2020, our general partner and its affiliates have approximately 40 employees performing services for our operations. The success of those employees drives the success of the business and supports our goal of long-term value creation for our unitholders. Our general partner offers competitive benefits and training programs to develop employees’ expertise and skillsets, use training, communication, appropriate investments and clear corporate policies to strive to provide a safe, harassment-free work environment guided by principles of fair and equal treatment, and prioritize employee engagement. Employees are committed to building strong, innovative and long-term relationships with each other and with affiliates. As a result, we believe that our general partner and its affiliates have a satisfactory relationship with those employees.

ITEM 1A. Risk Factors

Risk Factor Summary

We are providing the following summary of the risk factors contained in this Annual Report on Form 10-K to enhance the readability and accessibility of our risk factor disclosures. We encourage you to carefully review the full risk factors contained in this Annual Report on Form 10-K in their entirety for additional information regarding the material factors when considering an investment in our common units. These risks include, but are not limited to, the following:

• We may not generate sufficient distributable cash flow to support the payment of the minimum quarterly distribution to our unitholders.

• The amount of cash we will have available for distribution to unitholders depends primarily on our cash flow rather than on our profitability.

• Our growth strategy requires access to new capital; unfavorable capital markets could impair our ability to grow.

• If we are unable to make accretive acquisitions of real property interests or deploy accretive development infrastructure, our growth could be limited.

• We are dependent on Landmark for acquisitions and our ability to expand may be limited if Landmark’s business does not grow as expected. Additionally, Landmark may compete with us and will decide when, if, and how we complete acquisitions.

• We have limited experience developing real property interests associated with assets in the wireless communication and outdoor advertising industry.

• Our debt service payments will reduce our net income. Moreover, we may not be able to meet our debt service obligations and, to the extent that we cannot, we risk the loss of some or all of our assets to foreclosure or sale to satisfy our debt obligations.

• Landmark’s level of indebtedness, the terms of its borrowings and any future credit ratings could adversely affect our ability to grow our business, our ability to make cash distributions to our unitholders, and our ability to obtain debt financing.

• New technologies may significantly reduce demand for our wireless and digital infrastructure or negatively impact our revenue.

• Our business depends significantly on the demand for outdoor advertising and wireless communication, and we may be adversely affected by any slowdown in such demand. Additionally, a change in advertising strategies and/or zoning regulations may materially and adversely affect our business (including reducing demand for outdoor advertising space).

• Due to the long-term expectations of revenue from tenant leases, our results are sensitive to the creditworthiness and financial strength of our tenants and their sub-lessees. Our tenants, as well as their sub-lessees, are subject to governmental regulations, which may restrict their ability to operate. If our tenant leases are not renewed with similar terms, rental rates or at all, our future revenue may be materially affected.

• In the event infrastructure assets associated with certain of our real property interests are removed, replacement costs and governmental regulations may delay, restrict, prohibit, or substantially raise the cost of the installation of a similar infrastructure asset.

• A substantial portion of our revenue is derived from a small number of customers, and the loss, consolidation or financial instability of any of our limited number of customers may materially decrease revenue or reduce demand for our wireless infrastructure and network services.

• Restrictions in our revolving credit facility could adversely affect our results of operations, distributable cash flow and the value of our units.

• We expect to incur a significant amount of debt to finance our portfolio which may subject us to an increased risk of loss or adversely affect the return on our investments.

• COVID-19 and the future outbreak of other highly infectious or contagious diseases, could materially and adversely impact or disrupt our financial condition, results of operations, cash flows and performance.

• Our general partner and its affiliates, including Landmark, have conflicts of interest with us and limited fiduciary duties to us and our unitholders, and they may favor their own interests to our detriment and that of our unitholders. Additionally, we have no control over the business decisions and operations of Landmark, and Landmark is under no obligation to adopt a business strategy that favors us.

• Our partnership agreement (i) requires that we distribute all of our available cash, (ii) replaces our general partner’s fiduciary duties to holders of our common units with contractual standards governing its duties, (iii) restricts the remedies available to holders of our common units for actions taken by our general partner that might otherwise constitute breaches of fiduciary duty and (iv) includes exclusive forum, venue and jurisdiction provisions and a waiver of the right to a jury trial.

• Control of our general partner may be transferred to a third party without unitholder consent.

• The incentive distribution rights of our general partner may be transferred to a third party without unitholder consent.

• We may issue additional units without unitholder approval, which would dilute unitholder interests.

• Landmark and its affiliates may sell units in the public or private markets, and such sales could have an adverse impact on the trading price of the common units.

• Our general partner has a limited call right that may require you to sell your common units at an undesirable time or price.

21

• If the Internal Revenue Service (“IRS”) were to treat us as a corporation rather than as a partnership for federal income tax purposes, or if the REIT Subsidiary were to fail to qualify, or maintain its qualification, as a REIT, it could have significant adverse consequences to us and the value of our common units, preferred units and other partnership interests, and we could be subjected to a material amount of additional entity-level taxation thus reducing our cash available for distribution to our unitholders.

• Our unitholders’ share of our income is taxable to them for federal income tax purposes even if they do not receive any cash distributions from us.

• Ownership limitations and transfer restrictions may restrict or prevent you from engaging in certain transfers of our common units, preferred units, or other partnership interests.

• The tax treatment of REITs, publicly traded partnerships or an investment in our common units could be subject to legislative, judicial or administrative changes and differing interpretations, possibly on a retroactive basis.

• The REIT Subsidiary’s disposition of its assets may jeopardize its qualification as a REIT, or create additional tax liability for the REIT Subsidiary. In addition, to satisfy REIT distribution requirements, the REIT Subsidiary may need to borrow funds or dispose of assets at inopportune times, which could adversely affect our financial condition, results of operations, cash flow and the value of our common units, preferred units or other partnership interests.

• Tax-exempt entities and non-U.S. persons face unique tax issues from owning our common units that may result in adverse tax consequences to them.

Risk Factors

You should carefully consider the risks described below with all of the other information included in this Annual Report on Form 10-K. Limited partner interests are inherently different from the capital stock of a corporation, although many of the business risks to which we are subject are similar to those that would be faced by a corporation engaged in a similar business. If any of the following risks actually occur, they may materially harm our business, results of operations and distributable cash flow, as well as adversely affect the value of an investment in our common units.

Risks Related to Our Business

The ongoing pandemic of the novel coronavirus, or COVID-19, and the future outbreak of other highly infectious or contagious diseases, could materially and adversely impact or disrupt our financial condition, results of operations, cash flows and performance.

An epidemic, pandemic or similar serious public health issue, and the measures undertaken by governmental authorities to address it, could significantly disrupt or prevent us from operating our business in the ordinary course for an extended period, and could have a material adverse impact on our consolidated financial statements.

On March 11, 2020, the World Health Organization characterized the outbreak of COVID-19 as a global pandemic and recommended containment and mitigation measures. On March 13, 2020, the United States declared a national emergency concerning the outbreak, and several states and municipalities have declared public health emergencies. Along with these declarations, there have been extraordinary and wide-ranging actions taken by international, federal, state and local public health and governmental authorities to contain and combat the outbreak and spread of COVID-19 in regions across the United States and the world, including quarantines, and “stay-at-home” orders and similar mandates for many individuals to substantially restrict daily activities and for many businesses to curtail or cease normal operations.

As a result, the COVID-19 pandemic is negatively impacting almost every industry directly or indirectly, including industries in which our tenants operate. A number of our tenants have requested rent deferral or rent abatement during this pandemic. In addition, in response to these steps, in mid-March, our Sponsor and manager shifted its corporate office functions to work remotely. The effects of the executive order, including an extended period of remote work arrangements, could strain business continuity plans, introduce operational risk, including but not limited to cybersecurity risks, and impair the ability to manage our business. The COVID-19 pandemic, or a future pandemic, could also have material and adverse effects on our ability to successfully operate and on our financial condition, results of operations and cash flows due to, among other factors:

• the reduced economic activity severely impacts our tenants’ businesses, financial condition and liquidity and may cause one or more of our tenants to be unable to meet their obligations to us in full, or at all, or to otherwise seek modifications of such obligations;

• failure to pay real property taxes by the property owner or tenant could result in our real property interest being impaired or extinguished, or we may be forced to incur costs and pay the real property tax liability to avoid impairment of our assets;

• in the absence of a non-disturbance agreement, if the underlying property owner fails to comply with or make payments under debt arrangements senior to us, an event of default or foreclosure may result, which could have a material adverse effect on our results of operations and distributable cash flow;

• the reduced economic activity could result in a prolonged recession, which could negatively impact consumer discretionary spending;

• difficulty accessing debt and equity capital on attractive terms, or at all, impacts to our credit ratings, and a severe disruption and instability in the global financial markets or deteriorations in credit and financing conditions may affect our access to capital necessary to fund business operations or address maturing liabilities on a timely basis and our tenants’ ability to fund their business operations and meet their obligations to us;

22

• the financial impact of the COVID-19 pandemic could negatively impact our future compliance with financial covenants of our credit facility and other debt agreements and result in a default and potentially an acceleration of indebtedness, which non-compliance could negatively impact our ability to make additional borrowings under our revolving credit facility and pay distributions;

• the potential negative impact on the health of our personnel, particularly if a significant number of them are impacted, could result in a deterioration in our ability to ensure business continuity during this disruption.

The extent to which the COVID-19 pandemic impacts our operations and those of our tenants will depend on future developments, which are highly uncertain and cannot be predicted with confidence, including the scope, severity and duration of the pandemic, the actions taken to contain the pandemic or mitigate its impact, and the direct and indirect economic effects of the pandemic and containment measures, among others. Additional closures of our tenants’ businesses and early terminations by our tenants of their leases could reduce our cash flows, which could impact our ability to continue paying distributions to our unitholders at expected levels or at all.

The rapid development and fluidity of this situation precludes any prediction as to the full adverse impact of the COVID-19 pandemic. Nevertheless, the COVID-19 pandemic presents material uncertainty and risk with respect to our financial condition, results of operations, cash flows and performance.

We may not generate sufficient distributable cash flow to support the payment of the minimum quarterly distribution to our unitholders.

In order to support the payment of the minimum quarterly distribution of $0.2875 per unit per quarter, or $1.15 per unit on an annualized basis, we must generate distributable cash flow of approximately $7.3 million per quarter, or approximately $29.2 million per year, based on the number of common units outstanding as of December 31, 2020. We may not generate sufficient distributable cash flow each quarter to support the payment of the minimum quarterly distribution. The amount of cash we can distribute on our units principally depends upon the amount of cash we generate from our tenant leases, which may fluctuate from quarter to quarter based on, among other things:

• any cancellations under our tenant leases, which are typically cancelable with 30 to 180 days’ prior written notice;

• our lease renewal rate and the turnover rate in our tenant base;

• our ability to identify and secure suitable tenants for sites that may become available for lease;

• the amount and timing of rental payments under our tenant leases, including leases where rent is not paid monthly (such as leases where rent is paid annually);

• our ability to maintain or increase rents on our tenant leases;

• damage to our real property interests and/or our tenants’ assets caused by hurricanes, earthquakes, floods, fires, severe weather, explosions and other natural disasters and acts of terrorism; and

• prevailing economic and market conditions in the wireless communication, digital infrastructure, outdoor advertising and renewable power generation industries, as well as in the broader economy.

In addition, the actual amount of distributable cash flow we generate will also depend on other factors, some of which are beyond our control, including:

• the amount of our operating expenses and general and administrative expenses, including reimbursements to Landmark, some of which are not subject to any caps or other limits, in respect of those expenses;

• the level of capital expenditures we make;

• the cost of acquisitions, if any;

• our debt service requirements and other liabilities;

• changes in interest rates;

• fluctuations in our working capital needs;

• our ability to borrow funds and access capital markets;

• restrictions contained in our revolving credit facility and other debt service requirements;

• the amount of cash reserves established by our general partner;

• the viability of acquisitions and the returns on investment of various investment opportunities; and

• other business risks affecting our cash levels.

23

The amount of cash we will have available for distribution to unitholders depends primarily on our cash flow rather than on our profitability, which may prevent us from making distributions, even during periods in which we record net income.

The amount of cash we have available for distribution depends primarily on our cash flow and not solely on profitability, which will be affected by non-cash items. As a result, we may make cash distributions during periods when we record losses for financial accounting purposes and may not make cash distributions during periods when we record net earnings for financial accounting purposes.

Our growth strategy requires access to new capital; unfavorable capital markets could impair our ability to grow.

We continuously consider and enter into discussions regarding potential acquisitions or growth capital expenditures. Any limitations on our access to new capital will impair our ability to execute this strategy. If the cost of capital becomes too expensive, our ability to develop or acquire strategic and accretive assets will be limited. We may not be able to raise the necessary funds on satisfactory terms, if at all. The primary factors that influence our cost of equity include market conditions, including our then current unit price, fees we pay to underwriters and other offering costs, which include amounts we pay for legal and accounting services. Weak economic conditions and volatility and disruption in the financial markets could increase the cost of raising money in the debt and equity capital markets substantially while diminishing the availability of funds from those markets.

If we are unable to make accretive acquisitions of real property interests or deploy accretive development infrastructure, our growth could be limited.

We are experiencing increased competition for the types of real property interests we contemplate acquiring and developing. Weak economic conditions and competition for such acquisitions or developments could limit our ability to fully execute our growth strategy. Additionally, Landmark is not restricted from competing with us and has no obligation or duty to present us with acquisition opportunities. It may acquire and sell future real property interests to funds that it may sponsor in the future or other third parties. Please read “Conflicts of Interest.”

If we are unable to make accretive acquisitions from Landmark or third-parties, because, among other reasons, (i) Landmark does not offer other acquisition opportunities to us, (iii) we are unable to identify attractive third-party acquisition opportunities, (iv) we are unable to negotiate acceptable purchase contracts with Landmark or third parties, (v) we are unable to deploy accretive infrastructure developments, (vi) we are unable to obtain financing for these acquisitions on economically acceptable terms, (vii) we are outbid by competitors or (viii) we are unable to obtain necessary governmental or third-party consents, then our future growth and ability to increase distributions will be limited. Furthermore, even if we do make acquisitions and infrastructure developments that we believe will be accretive, these acquisitions and infrastructure developments may nevertheless result in a decrease in the cash generated from operations on a per unit basis. Any acquisition or infrastructure development involves potential risk, including, among other things:

• mistaken assumptions about revenue and costs, including potential growth;

• an inability to secure adequate tenant commitments to lease the acquired properties;

• an inability to integrate successfully the assets we acquire;

• the assumption of unknown liabilities for which we are not indemnified or for which our indemnity is inadequate;

• the diversion of management’s and employees’ attention from other business concerns; and

• unforeseen difficulties of operating in new geographic areas or industries.

We are dependent on Landmark for acquisitions and developments and our ability to expand may be limited if Landmark’s business does not grow as expected.

A major component of our growth strategy is dependent on acquisitions and developments from Landmark and its affiliates and third parties. We do not have any employees and will rely on Landmark to offer us acquisition opportunities and to provide acquisition services including identifying, underwriting and closing on acquisitions from third parties. If Landmark is unsuccessful in completing acquisitions for us, our growth will be limited.

Furthermore, our growth strategy depends on the growth of Landmark’s business. If Landmark focuses on other growth areas or does not or cannot make acquisitions of real property interests in our target industries, we may not be able to fully execute our growth strategy.

We have limited experience acquiring real property interests associated with assets in the renewable power generation industry and other fragmented industries and international real property interests.

Although we believe we will be able to effectively expand into new markets (in particular the renewable power generation industry), our experience in acquiring real property interests in the renewable power generation industry and other fragmented industries, as well as real property interests internationally, is limited. As a result, we may encounter unforeseen difficulties in our efforts to identify essential assets, assess

24

and underwrite the risk levels associated with such assets, negotiate favorable terms with property owners, negotiate favorable terms with operators of these assets, and comply with applicable laws and regulations.

If we are unable to correctly predict rental rates, cancellation rates, demand, consolidation trends and growth trends in these industries, a material adverse impact on our results of operations and distributable cash flow could result. If we are unable to effectively expand internationally or into the renewable power generation industry and other fragmented industries, our growth rate may be adversely impacted.

We may be unable to identify and complete digital infrastructure acquisitions.

We continually evaluate the market for available properties and may acquire data center properties. Our ability to complete acquisitions on favorable terms involves significant risks, including:

• we may be unable to acquire a desired property because of competition from other data center companies or real estate investors;

• even if we are able to acquire a desired property, competition from other potential acquirers may significantly increase the purchase price of such property;

• we may be unable to realize the intended benefits from acquisitions or achieve anticipated financial results;

• we may be unable to finance the acquisition on favorable terms or at all;

• we may incur significant costs associated with unrealized transactions.

Many of these risks will be outside of our control and any one of them could result in increased costs, decreases in the amount of expected revenue, and diversion of our management’s time and energy, which could adversely affect our business, financial condition and results of operations. If we are unable to successfully acquire data center properties, our ability to grow our business and compete will be significantly impaired, which could adversely affect our business, financial condition and results of operations.

Our data center properties may not be suitable for use other than as data centers, which could make it difficult to lease available space.

The risks associated with the illiquidity of real estate investments are even greater for data center properties. Data centers are highly specialized real estate assets containing extensive electrical and mechanical systems that are uniquely designed to house and maintain customer equipment and, as such, have little, if any, traditional office space. As a result, most data centers are not suited for use by customers as anything other than as data centers and major renovations and expenditures would be required in order to re-lease data center space for more traditional commercial or industrial uses, or to sell a property to a buyer for use other than as a data center.

Our tenants may choose to develop or relocate into new data centers or expand their own existing data centers, which could result in the loss of one or more key tenants.

Tenants may choose to develop or relocate to new data centers or expand or consolidate into their existing data centers that we do not own. In the event that any of our key tenants were to do so, it could result in a loss of business to us. If we lose a tenant, we cannot provide assurance that we would be able to replace that tenant at a competitive rate or at all, which could adversely affect our business, financial condition and results of operations.

A decrease in the demand for data center space could adversely affect our business, financial condition and results of operations.

Adverse developments in the data center market or in the industries in which customers operate could lead to a decrease in the demand for data center space or managed services. These adverse developments could include: a decline in the technology industry, such as a decrease in the use of mobile or web-based commerce, industry slowdowns, business layoffs or downsizing, relocation of businesses, increased costs of complying with existing or new government regulations and other factors; a slowdown in the growth of the internet generally as a medium for commerce and communication; a downturn in the market for data center space generally such as oversupply of or reduced demand for space; and the rapid development of new technologies or the adoption of new industry standards that render a customer’s products and services obsolete or unmarketable that contribute to a downturn in their businesses, increasing the likelihood of a default under their leases or that they become insolvent or file for bankruptcy protection. To the extent that any of these or other adverse conditions occur, they are likely to impact market rents for, and cash flows from, data center space.

25

Renewable power generation, including wind and solar power generation, is still in the early stages of its formation, and as such, widespread use of wind and solar generation assets may not develop. Weak growth in the renewable power generation industry could hamper our growth prospects.

Renewable power generation is only beginning to be implemented in the United States and, as such, renewable power sources such as wind turbines and solar arrays are not widespread. Part of our growth strategy is to continue to acquire real property interests in this industry, and a failure of the renewable power generation industry to grow quickly enough in the United States could negatively impact our future growth and negatively impact our future revenue.

We have limited experience developing real property interests associated with assets in the wireless communication and outdoor advertising industry.

Although we believe we will be able to effectively expand into new infrastructure developments, our experience in infrastructure developments within the wireless communication and outdoor advertising industries is limited. As a result, we may encounter unforeseen difficulties in our efforts to develop essential assets, assess and underwrite the risk levels associated with such assets, and comply with applicable laws and regulations.

If we are unable to correctly predict infrastructure development costs, rental rates, cancellation rates, demand, consolidation trends and growth trends in these industries, a material adverse impact on our results of operations and distributable cash flow could result. If we are unable to effectively deploy infrastructure developments, our growth rate may be adversely impacted.

Increases in interest rates could adversely impact the price of our common units, our ability to issue equity or incur debt for acquisitions or other purposes and our ability to make cash distributions at our intended levels.

Interest rates on future credit facilities and debt offerings could be higher than current levels, causing our financing costs to increase accordingly. As with other yield-oriented securities, our unit price will be impacted by our level of our cash distributions and our implied distribution yield. The distribution yield is often used by investors to compare and rank yield-oriented securities for investment decision-making purposes. As a result, changes in interest rates, either positive or negative, may affect the yield requirements of investors who invest in our units, and a rising interest rate environment could have an adverse impact on the price of our common units, our ability to issue equity or incur debt for acquisitions or other purposes and our ability to make cash distributions at our intended levels.

Our debt service payments will reduce our net income. Moreover, we may not be able to meet our debt service obligations and, to the extent that we cannot, we risk the loss of some or all of our assets to foreclosure or sale to satisfy our debt obligations.

We may not be able to access financing sources on favorable terms, or at all, which could adversely affect our ability to execute our business plan.

We intend to finance all or a portion of our acquisitions of real property interests through the issuance of debt, credit facility borrowings and a variety of other means. Our ability to access sources of financing will depend on various conditions in the markets for financing in this manner which are beyond our control, including lack of liquidity and greater credit spreads, prevailing interest rates and other factors. We cannot assure prospective investors that any sources of debt financing markets will become or remain an efficient and cost-effective source of long-term financing for our assets. If our current debt financing strategy is not viable, we will have to find alternative forms of financing for our acquisitions. This could require us to incur costlier financing which could result in a material adverse effect on our results of operations and distributable cash flow.

Our hedging strategy may be ineffective in reducing the impact of interest rate volatility on our cash flows, which could result in financial losses and adversely impact our distributable cash flow.

To achieve more predictable cash flow and to reduce our exposure to fluctuations in prevailing market interest rates, we intend to hedge interest rate risks related to a portion of our borrowings over time by means of interest rate swap agreements or other arrangements. To the extent that these derivative instruments are ineffective, fluctuations in market interest rates could result in financial losses and adversely impact our distributable cash flow.

If we are unable to borrow at favorable rates, we may not be able to acquire and develop new real property interests, which could reduce our income and our ability to make cash distributions to our unitholders.

If we are unable to borrow money at favorable rates, we may be unable to acquire and develop additional real property interests or refinance loans at maturity. Further, we will amend and restate the secured debt facilities as a new secured revolving credit facility and may enter into other credit arrangements that require us to pay interest on amounts we borrow at variable or “adjustable” rates. Increases in interest rates increase our interest costs. If interest rates are higher when we refinance our loans, our expenses will increase and we may not be able to pass on this added cost in the form of increased rents, thereby reducing our cash flow and the amount available for distribution to you. Further, during periods of rising interest rates, we may be forced to sell one or more of our real property interests in order to repay existing loans, which may not permit us to maximize the return on the particular real property interests being sold.

26

Landmark’s level of indebtedness, the terms of its borrowings and any future credit ratings could adversely affect our ability to grow our business, our ability to make cash distributions to our unitholders, and our ability to obtain debt financing.

If Landmark becomes over-levered, it would increase the risk that Landmark may default on its obligations to us under our omnibus agreement, including its agreement to cap the amount of our reimbursement for general and administrative expenses. We rely on Landmark for certain general and administrative services in support of managing and controlling our business and operations. The terms of Landmark’s indebtedness may limit its ability to borrow additional funds and may impact our operations in a similar manner. If Landmark were to default under its debt obligations, Landmark’s creditors could attempt to assert claims against our assets during the litigation of their claims against Landmark. The defense of any such claims could be costly and could materially impact our financial condition, absent any adverse determination. If these claims were successful, our ability to meet our obligations to our creditors, make distributions, and finance our operations could be materially adversely affected.

The industries in which our tenants and their sub-lessees operate could experience further consolidation, which may put one or more of our tenants or our tenants’ sub-lessees at risk of going out of business or significantly changing its operations.

Existing and potential tenants may enter into joint ventures, mergers, acquisitions or other cooperative agreements with other of our tenants. Such industry consolidation can potentially reduce the diversity of our tenant base and give tenants greater leverage over us, as their landlord, due to overlapping coverage, ability to increase co-location on nearby existing sites and through aggressive lease negotiations on multiple sites. Such actions have the potential to reduce our revenue in the future. Significant consolidation among our tenants in the wireless communication industry (or our tenants’ sub-lessees) may result in the decommissioning of certain existing communications sites, because certain portions of these tenants’ (or their sub-lessees’) networks may be redundant. There has been consolidation in the wireless communication industry historically that has led to certain lease terminations. The past consolidation in the wireless industry has led to rationalization of wireless networks and reduced demand for tenant sites. On April 1, 2020, T-Mobile and Sprint completed their merger. The loss of any one of our large customers as a result of joint ventures, mergers, acquisitions or other cooperative agreements may result in (1) a material decrease in our revenue, (2) an impairment of the value of our real property interests, or (3) other adverse effects to our business. In addition, certain combined companies have undergone or are currently undergoing a modernization of their networks, and these and other tenants and/or sub-lessees could determine not to renew leases with us (or our tenants) as a result. Our future results may be negatively impacted if a significant number of these leases are terminated, and our ongoing contractual revenue would be reduced as a result.

In addition, certain of our real property interests are rooftop wireless communication sites. Unlike a cellular tower, which will often accommodate multiple tenants through co-location, rooftop wireless communication sites are often rented to only one tenant. A cancellation by a tenant of its lease on a rooftop wireless site will therefore have a much greater effect on that real property interest than a cancellation by one tenant (of several co-located tenants) of its lease on a cellular tower.

Our business depends significantly on the demand for wireless communication and related wireless infrastructure, and we may be adversely affected by any slowdown in such demand. Additionally, a reduction in wireless carrier network investment may materially and adversely affect our business (including reducing demand for new tenant additions or network services).

We derive a significant amount of our revenue from our real property interests associated with wireless communication and related wireless infrastructure. This infrastructure ultimately depends on the demand for wireless voice and data services by consumers. The willingness of consumers to utilize the existing wireless infrastructure, and the willingness of our tenants to renew or extend existing leases, is affected by numerous factors, including:

• a decrease in consumer demand for wireless services due to general economic conditions or other factors;

• the financial condition of wireless carriers and/or cellular tower operators;

• the ability and willingness of wireless carriers and/or cellular tower operators to maintain or increase capital expenditures on network infrastructure;

• the growth rate of the wireless communication industry or of a particular industry segment;

• mergers or consolidations among wireless carriers and/or cellular tower operators;

• increased use of network sharing, roaming or resale arrangements by wireless carriers;

• delays or changes in the deployment of next generation wireless technologies;

• zoning, environmental, health or other government regulations or changes in the application and enforcement thereof; and

• unforeseen technological changes.

A slowdown in demand for wireless communication or wireless infrastructure may negatively impact our growth or otherwise have a material adverse effect on our results of operations and distributable cash flow.

27

New technologies may significantly reduce demand for our wireless infrastructure or negatively impact our revenue.

Improvements in the efficiency of wireless networks could reduce the demand for our tenants’ wireless infrastructure. For example, signal combining technologies that permit one antenna to service multiple frequencies and, thereby, multiple customers may reduce the need for our tenants’ wireless infrastructure. In addition, other technologies, such as Wi-Fi, femtocells, other small cells, or satellite (such as low earth orbiting) and mesh transmission systems may, in the future, serve as substitutes for, or alternatives to, leasing that might otherwise be anticipated on wireless infrastructure had such technologies not existed. Any significant reduction in wireless infrastructure leasing demand resulting from the previously mentioned technologies or other technologies may negatively impact our revenue or otherwise have a material adverse effect on us.

Our business depends significantly on the demand for outdoor advertising, and we may be adversely affected by any slowdown in such demand. Additionally, a change in advertising strategies and/or zoning regulations may materially and adversely affect our business (including reducing demand for outdoor advertising space).

We derive a significant amount of our revenue from our real property interests associated with the outdoor advertising industry. The value of these real property interests ultimately depends on the demand for outdoor advertising space and the market rates for advertising. The willingness of advertisers to utilize and willingness of billboard owners to upgrade existing bulletin boards, and the willingness of our tenants to renew or extend existing leases, is affected by numerous factors, including:

• a decrease in advertisers’ budgets due to general economic conditions or other factors;

• the financial condition of outdoor advertising companies and/or their customers;

• the ability and willingness of outdoor advertising companies to maintain or increase capital expenditures on upgrading bulletin billboards to digital billboards;

• mergers or consolidations among outdoor advertising companies;

• zoning, environmental, health or other government regulations or changes in the application and enforcement thereof; and

• unforeseen technological changes.

A slowdown in demand for outdoor advertising may negatively impact our growth or otherwise have a material adverse effect on our results of operations and distributable cash flow.

Due to the long-term expectations of revenue from tenant leases, our results are sensitive to the creditworthiness and financial strength of our tenants and their sub-lessees.

Due to the long-term nature of our tenant leases and their sub-leases, our performance is dependent on the continued financial strength of our tenants and their sub-lessees, many of whom operate with substantial leverage. Many tenants and potential tenants rely on capital raising activities to fund their operations and capital expenditures, and downturns in the economy or disruptions in the financial and credit markets may make it more difficult and more expensive to raise capital. If our tenants or sub-lessees (or potential tenants or sub-lessees) are unable to raise adequate capital to fund their business plans, they may reduce their spending, which could materially and adversely affect demand for our sites and equipment upgrades. If, as a result of a prolonged economic downturn or otherwise, one or more of our tenants experienced financial difficulties or filed for bankruptcy, it could result in uncollectible accounts receivable and an impairment of our deferred rent asset. In addition, it could result in the loss of significant customers and all or a portion of our anticipated lease revenue from certain tenants, all of which could have a material adverse effect on our business, results of operations and cash flows.

A tenant bankruptcy or insolvency could result in the termination of such tenant’s lease, which could reduce revenue.

Upon the bankruptcy of a tenant, typically the tenant would have the right to assume or reject the tenant’s lease at its option and we would not be permitted to terminate the tenant’s lease solely on the basis of such bankruptcy. The tenant will have until 120 days after the filing of bankruptcy to make a decision on assumption or rejection, subject to further extension of such time period by the bankruptcy court. In addition, contractual restrictions on the assignment of an unexpired lease of a bankrupt tenant are typically not enforceable. If a bankrupt tenant rejects a tenant lease, applicable provisions of the Bankruptcy Code will limit our claim for damages to the greater of any unpaid rent due under the lease on the earlier of (i) the date of filing of the bankruptcy case, or (ii) the date on which the leased property was repossessed or surrendered, plus (a) the “rent reserved” by the rejected lease for one year, or (b) for 15% of the remainder of the lease, not to exceed three years from the commencement of the case or the surrender of the property plus unpaid rent accrued prior to such date. These limitations could substantially reduce the claim we would be entitled to assert against the bankrupt tenant in the event the lease is rejected. Furthermore, even this limited claim for rent may not be fully paid in a bankruptcy proceeding, as such claim would share pro rata in recovery with all other general unsecured claims. Such provisions would result in a loss of significant anticipated lease revenue to us and adversely affect our revenue.

28

The bankruptcy or insolvency of an underlying property owner could result in the termination of our easement, lease assignment, or other real property interest.

Upon the bankruptcy of an underlying property owner, typically the property owner would have the right to assume or reject, at its option, any executory contracts. If a judge in a bankruptcy proceeding were to find that our real property interests are executory contracts, the underlying property owner would have the right to assume or reject such contracts in accordance with the bankruptcy rules. If a bankruptcy court finds that our real property interests are executory contracts and the underlying property owner rejects our contract, our remedies and claims for damages may be limited under bankruptcy law. Such events could have a material adverse impact on our business, results of operations and distributable cash flows.

Majority of our tenant leases may be terminated upon 30 to 180 days’ notice by our tenants, and unexpected lease cancellations could materially impact our cash flow from operations.

Most of our tenant leases permit our tenants to cancel the lease at any time with prior written notice. The termination provisions vary from lease to lease, but substantially all of our tenant leases require only 30 to 180 days’ advance notification. Cancellations are determined by the tenants themselves in their sole discretion. For instance, both wireless infrastructure and billboard sites are independently assessed by tenants for their ability to provide coverage and/or visibility. This assessment is made prior to construction or installation of the asset and there is no guarantee such coverage will remain static in the future due to independent developments, technological developments, foliage growth or other physical changes in the landscape that are unforeseeable and out of our control. Such results could lead to site removal or relocation to a more suitable location, leading to a reduction in our revenue. Any cancellations will adversely affect our revenue and cash flow, and a significant number of cancellations could materially impact our ability to pay distributions to our unitholders.

Our tenants may be exposed to force majeure events and other unforeseen events for which tenant insurance may not provide adequate coverage. Additionally, local restrictions may prevent or inhibit re-building efforts, particularly with outdoor advertising.

The sites underlying our real property interests are subject to risks associated with natural disasters, such as ice and wind storms, fires, tornadoes, floods, hurricanes and earthquakes, as well as other unforeseen damage. Should such a disaster cause damage to one of our tenant’s sites, certain of our tenant leases allow the tenant to either terminate the lease or withhold rent payments until the site is restored to its original condition. While our tenants generally maintain insurance coverage for natural disasters, they may not have adequate insurance to cover the associated costs of repair or reconstruction for a future major event. Further, in the event of any damage to our tenants’ assets, federal, state and local regulations may restrict the ability to repair or rebuild damaged assets – especially billboards or other signs, which are subject to significant regulations. If our tenants are unwilling or unable to repair or rebuild due to damage, we may experience losses in revenue due to terminated tenant leases and/or lease payments that are withheld pursuant to the terms of the tenant lease while the site is repaired.

Our tenants may experience equipment failure, which could lead to the termination of our tenant leases.

Our tenants’ assets are subject to a risk of equipment failure due to wear and tear, latent defect, design error or operator error, or early obsolescence. Additionally, substantially all of our tenant leases allow our tenants to terminate the lease upon 30 to 180 days’ notice. If our tenants choose to terminate their leases with us following an equipment failure, it could have a material adverse effect on our assets, liabilities, results of operations and cash flows.

In the event infrastructure assets associated with certain of our real property interests are removed, replacement costs and governmental regulations may delay, restrict, prohibit, or substantially raise the cost of the installation of a similar infrastructure asset.

Upon the expiration or termination of a tenant’s lease, most of our tenants have the right to remove their infrastructure assets associated with our real property interests, which are frequently subject to federal, state and local regulations, such as restrictive zoning. In the event that a tenant exercises its right or fulfills its obligation (as applicable) to remove its equipment, we would be unable to prevent such removal. There could be delays or significant costs associated with replacing the equipment and re-leasing that property, or replacement may be legally impossible. For example, if a legal nonconforming (“grandfathered”) billboard is removed, zoning regulations do not allow a replacement billboard to be constructed. Such events could have a material adverse impact on our business, results of operations and distributable cash flows.

Our tenants, as well as their sub-lessees, are subject to governmental regulations, which may restrict their ability to operate.

Our tenants, as well as their sub-lessees, may be subject to numerous federal, state and local regulations. For example, the outdoor advertising industry is subject to numerous restrictions, which has made it increasingly difficult to develop new outdoor advertising structures and sites. Changes in laws and regulations affecting outdoor advertising at any level of government, or increases in the enforcement of regulations could lead to the removal or modification of outdoor adverting structures and sites.

29

If our tenants are unable to obtain acceptable arrangements or compensation in circumstances in which their advertising structures and sites are subject to removal or modification, it could have an adverse effect on our tenants’, and in turn our own, business, results of operations and cash flow. In addition, governmental regulation of advertising displays could limit our tenants’ installation of new advertising displays, restrict advertising displays to governmentally controlled sites or permit the installation of advertising displays in a manner that benefits our tenants’ competitors disproportionately, any of which could have an adverse effect on our tenants’, and in turn our own, business, results of operations and cash flow.

Our other tenants, including those in the cellular tower and renewable power generation industries, are also subject to significant governmental regulations, which may impede or hamper their business operations or ability to grow. As legal requirements frequently change and are subject to interpretation and discretion, we may be unable to predict the ultimate cost of compliance with these requirements or their effect on our operations. Any new law, rule or regulation could require additional expenditure to achieve or maintain compliance or could adversely impact our tenants’ ability to generate and deliver energy.

Additionally, some of our tenants or their sub-lessees are required to maintain licenses, permits and governmental approvals for operation. Some of the licenses, permits and governmental approvals necessary to our tenants’ operations may contain conditions and restrictions, or may have limited terms. If our tenants or their sub-lessees fail to satisfy the conditions or comply with the restrictions imposed by such licenses, permits and governmental approvals, or the restrictions imposed by any statutory or regulatory requirements, they may become subject to regulatory enforcement action and the operation of their assets could be adversely affected or be subject to fines, penalties or additional costs or revocation of regulatory approvals, permits or licenses. If this were to happen, the ability of these tenants or their sub-lessees to continue to operate under our tenant leases may be jeopardized, which could adversely affect our revenue and cash flow.

A substantial portion of our revenue is derived from a small number of customers, and the loss, consolidation or financial instability of any of our limited number of customers may materially decrease revenue or reduce demand for our wireless infrastructure and network services.

For the year ended December 31, 2020, approximately 61% of our combined revenue was derived from T-Mobile, Clear Channel Outdoor, AT&T Mobility, Crown Castle, Outfront Media, Verizon, Sungard and American Tower (or their affiliates), which represented 14%, 11%, 7%, 6%, 6%, 6%, 6% and 5%, respectively, of our combined revenue. The loss of any one of our large customers as a result of consolidation, merger, bankruptcy, insolvency, network sharing, roaming, joint development, resale agreements by our customers or otherwise may result in (1) a material decrease in our revenue, (2) uncollectible account receivables, (3) an impairment of our deferred site rental receivables, wireless infrastructure assets, site rental contracts or customer relationships intangible assets, or (4) other adverse effects to our business. We cannot guarantee that contracts with our major customers will not be terminated or that these customers will renew their contracts with us. Additionally, our tenant leases with affiliates and subsidiaries of large, nationally-recognized companies may not provide for full recourse to the larger, more creditworthy parent entities affiliated with our lessees. In addition to our largest customers in the U.S., we also derive a portion of our revenue and anticipated future growth from customers offering or contemplating offering emerging wireless services; such customers are smaller and have less financial resources than our Tier 1 tenants, have business models which may not be successful, or may require additional capital. Please read Note 19 to the Notes to the Consolidated Financial Statements included elsewhere in this annual report.

Our real property interests currently have significant concentration in a small number of top Basic Trading Areas (“BTAs”).

Real property interests in the top 10 BTAs currently account for approximately 53% of our quarterly rental revenue. The New York BTA and the Los Angeles BTA are our top BTAs and accounted for 17% and 15% of our quarterly rental revenue for the three months ended December 31, 2020, respectively. No other single BTA accounted for more than 8% of our quarterly rental revenue for the three months ended December 31, 2020. We are susceptible to adverse developments in the economy, weather conditions, competition, consumer preferences, demographics, or other factors in these major metropolitan areas. Due to our susceptibility to such adverse developments, there can be no assurance that the current geographic concentration of our business will not have a material adverse effect on our results of operations and distributable cash flow.

If our tenant leases are not renewed with similar terms, rental rates or at all, our future revenue may be materially affected.

Approximately 20% of our tenant leases will be subject to extension over the next 12 months. Our tenants are under no obligation to extend their tenant leases. In addition, there is no assurance that current tenants will renew their current leases with similar terms or rental rates, or even at all. The extension, renewal, or replacement of existing leases depends on a number of factors beyond our control, including the level of existing and new competition in our markets, the macroeconomic factors affecting lease economics for our current and potential customers, the balance of supply and demand, on a short-term, seasonal and long-term basis, in our markets, the extent to which customers in our markets are willing to contract on a long-term basis, and the effects of federal, state or local regulations on the contracting practices of our customers.

Unsuccessful negotiations could potentially reduce revenue generated from the assets and could have a material adverse effect on our results of operations and distributable cash flow.

We may enter into additional credit agreements or mortgage, pledge, hypothecate or grant a security interest in all or substantially all of our assets without prior approval of our unitholders.

We may mortgage, pledge, hypothecate or grant a security interest in all or substantially all of our assets without prior approval of our unitholders. For example, our revolving credit facility is secured by substantially all of our assets. If we were to decide at any time to incur debt and secure our obligations or indebtedness by all or substantially all of our assets, and if we were unable to satisfy such obligations or repay such indebtedness, the lenders could seek to foreclose on our assets. The lenders could also sell all or substantially all of our assets under such foreclosure or other realization upon those encumbrances without prior approval of our unitholders, which would adversely affect the price of our common units. In addition, we may enter into additional credit agreement of other debt arrangements in the future that may be secured by all or substantially all of our assets.

Restrictions in our revolving credit facility could adversely affect our results of operations, distributable cash flow and the value of our units.

We will be dependent upon the earnings and cash flow generated by our operations in order to meet any debt service obligations and to allow us to make cash distributions to our unitholders. The operating and financial restrictions and covenants in our revolving credit facility and any future financing agreements could restrict our ability to finance our future operations or capital needs or to expand or pursue our business activities, which may, in turn, limit our ability to make cash distributions to our unitholders.

The provisions of our revolving credit facility may affect our ability to obtain future financing and pursue attractive business opportunities and our flexibility in planning for, and reacting to, changes in business conditions. In addition, a failure to comply with the provisions of our revolving credit facility could result in an event of default which would enable our lenders to declare the outstanding principal of that debt, together with accrued interest, to be immediately due and payable. If the payment of our debt is accelerated, defaults under our other debt instruments, if any, may be triggered, and our assets may be insufficient to repay such debt in full, and the holders of our units could experience a partial or total loss of their investment. Please read “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Liquidity and Capital Resources” for additional information about our revolving credit facility.

Certain of our real property interests are subordinated to senior debt such as mortgages, which, if we fail to obtain a non-disturbance agreement, could foreclose on our real property interests if the underlying property owner defaults on the mortgage.

While we make an effort to obtain non-disturbance agreements on the real property interests we acquire, sometimes we are unable to do so. Under certain circumstances and in the absence of a non-disturbance agreement, if the underlying property owner fails to comply with or make payments under debt arrangements senior to us, an event of default may result, which would allow the creditors to foreclose on any of our real property interests associated with that site. Any such default or foreclosure could have a material adverse effect on our results of operations and distributable cash flow.

We expect to incur a significant amount of debt to finance our portfolio which may subject us to an increased risk of loss or adversely affect the return on our investments.

We expect to incur a significant amount of debt to finance our operations. We expect to finance our acquisitions through the issuance of debt, borrowing under credit facilities, and other arrangements. We anticipate that the leverage we employ will vary depending on our ability to sell our debt, obtain credit facilities, the loan-to-value and debt service coverage ratios of our assets, the yield on our assets, the targeted leveraged return we expect from our portfolio and our ability to meet ongoing covenants related to our asset mix and financial performance. Substantially all of our assets are currently pledged as collateral under our revolving credit facility. Our results of operations and distributable cash flow may be adversely affected to the extent that changes in market conditions cause the cost of our financing to increase. In addition to our revolving credit facility, we may enter into additional credit agreements or other debt arrangements in the future.

If we are unable to protect our rights to our real property interests, our business and operating results could be adversely affected.

Our real property interests consist primarily of rights under leases and long-term or perpetual easements. A loss of these interests at a particular site may interfere with our ability to generate revenue. For various reasons, we may not always have the ability to access, analyze and verify all information regarding zoning and other issues prior to completing an acquisition of real property interests, which can affect our rights to access and lease a site. Our inability to protect our rights to our real property interests may have a material adverse effect on our results of operations and distributable cash flow.

31

The value of our real property interests are affected by a number of factors, including changes in the general economic climate, local conditions (such as an oversupply of, or a reduction in demand for, our real property interest), competition based on rental rates, attractiveness and location of the properties, physical condition of the properties, financial condition of buyers and sellers of properties, and changes in operating costs. If our real property interests do not generate sufficient revenue to meet their operating expenses, including debt service, our cash flow and ability to pay distributions to unitholders will be adversely affected. Real estate values are also affected by such factors as government regulations, interest rate levels, the availability of financing, participation by other investors in the financial markets and potential liability under changing laws. Under eminent domain laws, governments can take real property without the owner’s consent, sometimes for less compensation than the owner believes the property is worth. In addition, the breach of our easement or lease assignment by an underlying property owner or a tenant could interfere with our operations. Any of these factors could have an adverse impact on our business, financial condition, results of operations or distributable cash flow.

We may be subject to unanticipated liabilities as a result of our real property interests.

We own real property interests and are parties to contracts with unrelated parties such as tenants. We may be involved in disputes and other matters with property owners, tenants, their respective employees and agents, and other unrelated parties, such as tort claims related to hazardous conditions, foreclosure actions and access disputes. We cannot assure you that we will not become subject to material litigation or other liabilities. If these liabilities are not adequately covered by insurance, they could have a material adverse impact on our results of operations and distributable cash flow.

Our real property interests generally do not make us contractually responsible for the payment of real property taxes. If the responsible party fails to pay real property taxes, the resulting tax lien could put our real property interest in jeopardy.

Substantially all of our real property interests are subject to triple net or effectively triple net lease arrangements under which we are not responsible for paying real property taxes. If the property owner or tenant fails to pay real property taxes, any lien resulting from such unpaid taxes would be senior to our real property interest in the applicable site. Failure to pay such real property taxes could result in our real property interest being impaired or extinguished, or we may be forced to incur costs and pay the real property tax liability to avoid impairment of our assets.

Our tenant leases generally make our tenants contractually responsible for payment of taxes, maintenance, insurance and other similar expenditures associated with our tenants’ infrastructure assets. If our tenants fail to pay these expenses as required, it could result in a material adverse impact on our results of operations and distributable cash flow.

As part of our triple net and effectively triple net lease arrangements, our tenant lease agreements typically make our tenants contractually responsible for payment of taxes, maintenance, insurance and other similar expenditures associated with our tenants’ infrastructure assets. If our tenants fail to pay these expenses as required, it could result in a diminution in the value of the infrastructure asset associated with our real property interest and have a material adverse impact on our results of operations and distributable cash flow.

If radio frequency emissions from wireless handsets or equipment on wireless infrastructure are demonstrated to cause negative health effects, potential future claims could adversely affect our tenants’ operations, costs or revenue.

The potential connection between radio frequency emissions and certain negative health effects, including some forms of cancer, has been the subject of substantial study by the scientific community in recent years, and numerous health-related lawsuits have been filed against wireless carriers and wireless device manufacturers. We cannot guarantee that claims relating to radio frequency emissions will not arise in the future or that the results of such studies will not be adverse to us or our tenants.

Public perception of possible health risks associated with wireless communication may slow or diminish the growth of wireless carriers, which may in turn impact our revenue. In particular, negative public perception of, and regulations regarding, these perceived health risks may slow or diminish the market acceptance of wireless communication services and increase opposition to the development and expansion of wireless antenna sites. If a scientific study or court decision resulted in a finding that radio frequency emissions posed health risks to consumers, it could negatively impact the market for wireless services, as well as our wireless carrier tenants, which could materially and adversely affect our business, results of operations and distributable cash flow.

If we fail to maintain an effective system of internal controls, we may not be able to report our financial results accurately or prevent fraud, which would likely have a negative impact on the market price of our common units.

We prepare our financial statements in accordance with accounting principles generally accepted in the United States of America (“GAAP”). Effective internal controls are necessary for us to provide reliable financial reports, prevent fraud and to operate successfully as a publicly traded partnership. Our efforts to maintain our internal controls may not be successful, and we may be unable to maintain effective controls over our financial processes and reporting in the future or to comply with our obligations under Section 404 of the Sarbanes-Oxley Act of 2002, which we refer to as Section 404. For example, Section 404 requires us, among other things to annually review and report on the effectiveness of our internal controls over financial reporting. Any failure to develop, implement or maintain effective internal controls or to

32

improve our internal controls could harm our operating results or cause us to fail to meet our reporting obligations. Given the difficulties inherent in the design and operation of internal controls over financial reporting, we can provide no assurance as to our conclusions about the effectiveness of our internal controls, and we may incur significant costs in our efforts to comply with Section 404. Ineffective internal controls will subject us to regulatory scrutiny and a loss of confidence in our reported financial information, which could have an adverse effect on our business and would likely have a negative effect on the trading price of our common units.

We may incur asset impairment charges, which could result in a significant reduction to our earnings.

We review our assets annually to determine if any are impaired, or more frequently in the event of circumstances indicating potential impairment. These circumstances could include a decline in our actual or expected future cash flow or income, a significant adverse change in the business climate, a decline in market capitalization, or slower growth rates in our industry, among others. If we determine that an asset is impaired, we may be required to record a non-cash impairment charge which would reduce our earnings and negatively impact our results of operations.

Terrorist or cyber-attacks and threats, or escalation of military activity in response to these attacks, could have a material adverse effect.

Terrorist attacks and threats, cyber-attacks, or escalation of military activity in response to these attacks, may have significant effects on general economic conditions, fluctuations in consumer confidence and spending and market liquidity, each of which could materially and adversely affect our business. Strategic targets, such as communication-related assets and power generation assets, may be at greater risk of future terrorist or cyber-attacks than other targets in the United States. We do not maintain specialized insurance for possible liability or loss resulting from a cyber-attack on our assets that may shut down all or part of our business. It is possible that any of these occurrences, or a combination of them, could have a material adverse effect on our results of operations and distributable cash flow.

While our agreements with our lessees, property owners and other surface owners generally include environmental representations, warranties, and indemnities to minimize the extent to which we may be financially responsible for liabilities arising under environmental laws, unforeseen liabilities under these laws could have a material adverse effect on our results of operations and distributable cash flow.

Laws and regulations governing the discharge of materials into the environment or otherwise relating to the protection of the environment are applicable to our business and operations, and also to the businesses and operations of our lessees, property owners and other surface owners or operators. Federal, state and local government agencies issue regulations that often require difficult and costly compliance measures that carry substantial administrative, civil and criminal penalties and that may result in injunctive obligations for non-compliance. These laws and regulations often require permits before operations commence, restrict the types, quantities and concentrations of various substances that can be released into the environment, require remediation of released substances, and limit or prohibit construction or operations on certain lands (e.g. wetlands). We do not conduct any operations on our properties, but we or our tenants may maintain small quantities of materials that, if released, would be subject to certain environmental laws. Similarly, our property owners, lessees and other surface interest owners may have liability or responsibility under these laws which could have an indirect impact on our business. These laws include but are not limited to the federal RCRA, and comparable state statutes and regulations promulgated thereunder (which impose requirements on the generation, transportation, treatment, storage, disposal and cleanup of hazardous and non-hazardous wastes) and CERCLA, and analogous state laws (which generally impose liability, without regard to fault or legality of the original conduct, on classes of persons who are considered to be responsible for the release of hazardous substances into the environment, including the current and former owners or operators of a site). It is not uncommon for neighboring property owners and other third-parties to file claims for personal injury and property damage allegedly caused by the hazardous substances released into the environment. Therefore, governmental agencies or third parties may seek to hold us, our lessees, property owners and other surface interest owners responsible under CERCLA and comparable state statutes for all or part of the costs to cleanup sites at which hazardous substances have been released. Our agreements with our lessees, counterparties and other surface owners generally include environmental representations, warranties, and indemnities to minimize the extent to which we may be financially responsible for liabilities arising under these laws.

Risks Inherent in an Investment in Us

Our general partner and its affiliates, including Landmark, have conflicts of interest with us and limited fiduciary duties to us and our unitholders, and they may favor their own interests to our detriment and that of our unitholders. Additionally, we have no control over the business decisions and operations of Landmark, and Landmark is under no obligation to adopt a business strategy that favors us.

As of December 31, 2020, Landmark and affiliates own a 13.4% limited partner interest in us and own and control our general partner through a non-economic interest in us. Although our general partner has a duty to manage us in a manner that is in the best interests of our partnership and our unitholders, the directors and officers of our general partner also have a duty to manage our general partner in a manner that is in the best interests of its owner, Landmark. Conflicts of interest may arise between Landmark and its affiliates, including our general partner, on the one hand, and us and our unitholders, on the other hand. In resolving these conflicts, the general partner may favor its own interests and the interests of its affiliates, including Landmark, over the interests of our common unitholders. These conflicts include, among others, the following situations:

• neither our partnership agreement nor any other agreement requires Landmark to pursue a business strategy that favors us or utilizes our assets, which could involve decisions by Landmark to pursue and grow particular markets, or undertake acquisition opportunities for itself;

• Landmark may be constrained by the terms of its debt instruments from taking actions, or refraining from taking actions, that may be in our best interests;

• our partnership agreement replaces the fiduciary duties that would otherwise be owed by our general partner with contractual standards governing its duties, limiting our general partner’s liabilities and restricting the remedies available to our unitholders for actions that, without the limitations, might constitute breaches of fiduciary duty;

• except in limited circumstances, our general partner has the power and authority to conduct our business without unitholder approval;

• our general partner will determine the amount and timing of asset purchases and sales, borrowings, issuance of additional partnership securities and the creation, reduction or increase of cash reserves, each of which can affect our distributable cash flow;

• our general partner will determine the amount and timing of many of our cash expenditures and whether a cash expenditure is classified as an expansion capital expenditure, which would not reduce operating surplus, or a maintenance capital expenditure, which would reduce our operating surplus. This determination can affect the amount of available cash from operating surplus that is distributed to our unitholders and to our general partner and the amount of adjusted operating surplus generated in any given period;

• our general partner will determine which costs incurred by it are reimbursable by us;

• our general partner may cause us to borrow funds in order to permit the payment of cash distributions, even if the purpose or effect of the borrowing is to make incentive distributions;

• our partnership agreement permits us to classify up to $10.0 million as operating surplus, even if it is generated from asset sales, non-working capital borrowings or other sources that would otherwise constitute capital surplus. This cash may be used to fund distributions to our general partner in respect of the incentive distribution rights;

• our partnership agreement does not restrict our general partner from causing us to pay it or its affiliates for any services rendered to us or entering into additional contractual arrangements with any of these entities on our behalf;

• our general partner intends to limit its liability regarding our contractual and other obligations;

• our general partner may exercise its right to call and purchase all of the common units not owned by it and its affiliates if it and its affiliates own more than 80% of the common units;

• our general partner controls the enforcement of obligations owed to us by our general partner and its affiliates, including our commercial agreements with Landmark;

• our general partner decides whether to retain separate counsel, accountants or others to perform services for us; and

• our general partner may elect to cause us to issue common units to it in connection with a resetting of the target distribution levels related to our general partner’s incentive distribution rights without the approval of the conflicts committee of the board of directors of our general partner (which we refer to as our “conflicts committee”), or our unitholders. This election may result in lower distributions to our common unitholders in certain situations.

34

Under the terms of our partnership agreement, the doctrine of corporate opportunity, or any analogous doctrine, does not apply to our general partner or any of its affiliates, including Landmark, and their respective executive officers, directors and owners. Any such person or entity that becomes aware of a potential transaction, agreement, arrangement or other matter that may be an opportunity for us will not have any duty to communicate or offer such opportunity to us. Any such person or entity will not be liable to us or to any limited partner for breach of any fiduciary duty or other duty by reason of the fact that such person or entity pursues or acquires such opportunity for itself, directs such opportunity to another person or entity or does not communicate such opportunity or information to us. This may create actual and potential conflicts of interest between us and affiliates of our general partner and result in less than favorable treatment of us and our unitholders. Please read Item 13., “Certain Relationships and Related Transactions, and Director Independence – Agreements Governing the Transactions – Omnibus Agreement” and “Conflicts of Interest.”

Our general partner intends to limit its liability regarding our obligations.

Our general partner intends to limit its liability under contractual arrangements so that the counterparties to such arrangements have recourse only against our assets, and not against our general partner or its assets. Our general partner may therefore cause us to incur indebtedness or other obligations that are nonrecourse to our general partner. Our partnership agreement permits our general partner to limit its liability, even if we could have obtained more favorable terms without the limitation on liability. In addition, we are obligated to reimburse or indemnify our general partner to the extent that it incurs obligations on our behalf. Any such reimbursement or indemnification payments would reduce the amount of cash otherwise available for distribution to our unitholders.

Our partnership agreement requires that we distribute all of our available cash, which could limit our ability to grow and make acquisitions.

Our partnership agreement requires that we distribute all of our available cash to our unitholders. As a result, we expect to rely primarily upon external financing sources, including commercial bank borrowings and the issuance of debt and equity securities, to fund our acquisitions and expansion capital expenditures. Therefore, to the extent we are unable to finance our growth externally, our cash distribution policy will significantly impair our ability to grow. In addition, because we will distribute all of our available cash, our growth may not be as fast as that of businesses that reinvest their available cash to expand ongoing operations. To the extent we issue additional units in connection with any acquisitions or expansion capital expenditures, the payment of distributions on those additional units may increase the risk that we will be unable to maintain or increase our per unit distribution level. There are no limitations in our partnership agreement on our ability to issue additional units, including units ranking senior to our common units as to distributions or in liquidation or that have special voting rights and other rights, and our unitholders will have no preemptive or other rights (solely as a result of their status as unitholders) to purchase any such additional units. The incurrence of additional commercial borrowings or other debt to finance our growth strategy would result in increased interest expense, which, in turn, may reduce the amount of cash that we have available to distribute to our unitholders.

Our partnership agreement replaces our general partner’s fiduciary duties to holders of our common units with contractual standards governing its duties.

Delaware law provides that Delaware limited partnerships may, in their partnership agreements, expand, restrict or eliminate the fiduciary duties otherwise owed by the general partner to limited partners and the partnership, provided that partnership agreements may not eliminate the implied contractual covenant of good faith and fair dealing. This implied covenant is a judicial doctrine utilized by Delaware courts in connection with interpreting ambiguities in partnership agreements and other contracts and does not form the basis of any separate or independent fiduciary duty in addition to the express contractual duties set forth in our partnership agreement. Under the implied contractual covenant of good faith and fair dealing, a court will enforce the reasonable expectations of the parties where the language in the partnership agreement does not provide for a clear course of action.

As permitted by Delaware law, our partnership agreement contains provisions that eliminate the fiduciary standards to which our general partner would otherwise be held by state fiduciary duty law and replaces those duties with several different contractual standards. For example, our partnership agreement permits our general partner to make a number of decisions in its individual capacity, as opposed to in its capacity as our general partner, free of any duties to us and our unitholders. This provision entitles our general partner to consider only the interests and factors that it desires and relieves it of any duty or obligation to give any consideration to any interest of, or factors affecting, us, our affiliates or our limited partners. By purchasing a common unit, a unitholder is treated as having consented to the provisions in our partnership agreement, including the provisions discussed above. Please read “Conflicts of Interest” and “Duties of the General Partner.”

35

Our partnership agreement restricts the remedies available to holders of our common units for actions taken by our general partner that might otherwise constitute breaches of fiduciary duty.

Our partnership agreement contains provisions that restrict the remedies available to unitholders for actions taken by our general partner that might otherwise constitute breaches of fiduciary duty under state fiduciary duty law. For example, our partnership agreement:

• provides that whenever our general partner makes a determination or takes, or declines to take, any other action in its capacity as our general partner, our general partner is required to make such determination, or take or decline to take such other action, in good faith, meaning that it subjectively believed that the determination or the decision to take or decline to take such action was in the best interests of our partnership, and will not be subject to any other or different standard imposed by our partnership agreement, Delaware law, or any other law, rule or regulation, or at equity;

• provides that our general partner will not have any liability to us or our unitholders for decisions made in its capacity as a general partner so long as it acted in good faith;

• provides that our general partner and its officers and directors will not be liable for monetary damages to us or our limited partners resulting from any act or omission unless there has been a final and non-appealable judgment entered by a court of competent jurisdiction determining that our general partner or its officers and directors, as the case may be, acted in bad faith or engaged in fraud or willful misconduct or, in the case of a criminal matter, acted with knowledge that the conduct was criminal; and

• provides that our general partner will not be in breach of its obligations under our partnership agreement or its fiduciary duties to us or our limited partners if a transaction with an affiliate or the resolution of a conflict of interest is approved in accordance with, or otherwise meets the standards set forth in, our partnership agreement.

In connection with a situation involving a transaction with an affiliate or a conflict of interest, our partnership agreement provides that any determination by our general partner must be made in good faith, and that our conflicts committee and the board of directors of our general partner are entitled to a presumption that they acted in good faith. In any proceeding brought by or on behalf of any limited partner or the partnership, the person bringing or prosecuting such proceeding will have the burden of overcoming such presumption. Please read “Conflicts of Interest.”

Cost reimbursements, which are determined in our general partner’s sole discretion, and fees due to our general partner and its affiliates for services provided will be substantial and will reduce the amount of cash we have available for distribution to you.

Under our partnership agreement, we are required to reimburse our general partner and its affiliates for all costs and expenses that they incur on our behalf for managing and controlling our business and operations. Except to the extent specified under our omnibus agreement, our general partner determines the amount of these expenses. Under the omnibus agreement, which was amended on January 30, 2019, we agreed to reimburse Landmark for expenses related to certain general and administrative services Landmark provides to us in support of our business, subject to a quarterly cap equal to 3% of our revenue during the current calendar quarter. This cap on expenses will last until the earlier to occur of: (i) the date on which our revenue for the immediately preceding four consecutive fiscal quarters exceeded $120 million and (ii) November 19, 2021. Some of the costs and expenses for which we are required to reimburse our general partner and its affiliates are not subject to any caps or other limits. Payments to our general partner and its affiliates will be substantial and will reduce the amount of cash we have available to distribute to unitholders.

Unitholders have very limited voting rights and, even if they are dissatisfied, they have limited ability to remove our general partner.

Unlike the holders of common stock in a corporation, unitholders have only limited voting rights on matters affecting our business and, therefore, limited ability to influence management’s decisions regarding our business. For example, unlike holders of stock in a public corporation, unitholders do not have “say-on-pay” advisory voting rights. Unitholders did not elect our general partner or the board of directors of our general partner and will have no right to elect our general partner or the board of directors of our general partner on an annual or other continuing basis. The board of directors of our general partner is chosen by the member of our general partner, which is a wholly owned subsidiary of Landmark. Furthermore, if the unitholders are dissatisfied with the performance of our general partner, they will have little ability to remove our general partner. As a result of these limitations, the price at which our common units will trade could be diminished because of the absence or reduction of a takeover premium in the trading price.

The vote of the holders of at least 66 ²/₃ % of all outstanding common units is required to remove our general partner. As of December 31, 2020, Landmark and its affiliates own 3,415,405 common units, which represents a 13.4% limited partner interest in us.

“Cause” is narrowly defined under our partnership agreement to mean that a court of competent jurisdiction has entered a final, non-appealable judgment finding the general partner liable for actual fraud or willful or wanton misconduct in its capacity as our general partner. Cause does not include most cases of charges of poor management of the business.

Furthermore, unitholders’ voting rights are further restricted by the partnership agreement provision providing that any units held by a person that owns 20% or more of any class of units then outstanding, other than our general partner, its affiliates, their transferees, and persons who acquired such units with the prior approval of the board of directors of our general partner, cannot vote on any matter.

36

Our partnership agreement also contains provisions limiting the ability of unitholders to call meetings or to acquire information about our operations, as well as other provisions limiting the unitholders’ ability to influence the manner or direction of management.

Control of our general partner may be transferred to a third party without unitholder consent.

Our general partner may transfer its general partner interest to a third party in a merger or in a sale of all or substantially all of its assets without the consent of the unitholders. Furthermore, there is no restriction in our partnership agreement on the ability of Landmark to transfer its membership interest in our general partner to a third party. The new owner of our general partner would then be in a position to replace the board of directors and officers of our general partner with its own choices.

The incentive distribution rights of our general partner may be transferred to a third party without unitholder consent.

Our general partner may transfer its incentive distribution rights to a third party at any time without the consent of our unitholders. If our general partner transfers its incentive distribution rights to a third party, it will have less incentive to grow our partnership and increase distributions. A transfer of incentive distribution rights by our general partner could reduce the likelihood of Landmark selling or contributing additional assets to us, which in turn would impact our ability to grow our asset base.

We may issue additional units without unitholder approval, which would dilute unitholder interests.

At any time, we may issue an unlimited number of general partner interests or limited partner interests of any type without the approval of our unitholders, and our unitholders will have no preemptive or other rights (solely as a result of their status as unitholders) to purchase any such general partner interests or limited partner interests. Further, there are no limitations in our partnership agreement on our ability to issue equity securities that rank equal or senior to our common units as to distributions or in liquidation or that have special voting rights and other rights. The issuance by us of additional common units or other equity securities of equal or senior rank will have the following effects:

• our unitholders’ proportionate ownership interest in us will decrease;

• the amount of cash we have available to distribute on each unit may decrease;

• the ratio of taxable income to distributions may increase;

• the relative voting strength of each previously outstanding unit may be diminished; and

• the market price of our common units may decline.

The issuance by us of additional general partner interests may have the following effects, among others, if such general partner interests are issued to a person who is not an affiliate of Landmark:

• management of our business may no longer reside solely with our current general partner; and

• affiliates of the newly admitted general partner may compete with us, and neither that general partner nor such affiliates will have any obligation to present business opportunities to us.

Landmark and its affiliates may sell units in the public or private markets, and such sales could have an adverse impact on the trading price of the common units.

As of December 31, 2020, Landmark and its affiliates hold 3,415,405 common units. We have agreed to provide Landmark and its affiliates with certain registration rights under applicable securities laws. The sale of these units in the public or private markets could have an adverse impact on the price of the common units or on any trading market that may develop.

Other than the requirement in our partnership agreement to distribute all of our available cash each quarter, we have no legal obligation to make quarterly cash distributions, and our general partner has considerable discretion to establish cash reserves that would reduce the amount of available cash we distribute to unitholders.

Generally, our available cash is comprised of cash on hand at the end of a quarter plus cash-on-hand resulting from any working capital borrowings made after the end of the quarter less cash reserves established by our general partner. Our partnership agreement permits our general partner to establish cash reserves for the proper conduct of our business (including reserves for our future capital expenditures and anticipated future debt service requirements), to comply with applicable law or agreements to which we are a party, or to provide funds for future distributions to unitholders. As a result, even when there is no change in the amount of distributable cash flow that we generate, our general partner has considerable discretion to establish cash reserves, which would result in a reduction the amount of available cash we distribute to unitholders. Accordingly, there is no guarantee that we will make quarterly cash distributions to our unitholders at our minimum quarterly distribution rate or at any other rate, and we have no legal obligation to do so, except to the extent we have available cash as defined in our partnership agreement.

37

Landmark may compete with us, and Landmark, as owner of our general partner, will decide when, if, and how we complete acquisitions.

Neither our partnership agreement nor our omnibus agreement prohibit Landmark or any other affiliates of our general partner from owning assets or engaging in businesses that compete directly or indirectly with us. Under the terms of our partnership agreement, the doctrine of corporate opportunity, or any analogous doctrine, does not apply to our general partner or any of its affiliates, including Landmark. Any such entity that becomes aware of a potential transaction, agreement, arrangement or other matter that may be an opportunity for us does not have any duty to communicate or offer such opportunity to us. Consequently, Landmark and other affiliates of our general partner may acquire additional assets in the future without any obligation to offer us the opportunity to purchase any of those assets. As a result, competition from Landmark and other affiliates of our general partner could materially and adversely impact our results of operations and distributable cash flow.

Our general partner has a limited call right that may require you to sell your common units at an undesirable time or price.

If at any time our general partner and its affiliates own more than 80% of our then-outstanding common units, our general partner will have the right, but not the obligation, which it may assign to any of its affiliates or to us, to acquire all, but not less than all, of the common units held by unaffiliated persons at a price not less than their then-current market price. As a result, you may be required to sell your common units at an undesirable time or price and may not receive any return on your investment. You may also incur a tax liability upon a sale of your units.

Your liability may not be limited if a court finds that unitholder action constitutes control of our business.

A general partner of a partnership generally has unlimited liability for the obligations of the partnership, except for those contractual obligations of the partnership that are expressly made without recourse to the general partner. Our partnership is organized under Delaware law, and we conduct business in a number of other states. The limitations on the liability of holders of limited partner interests for the obligations of a limited partnership have not been clearly established in some of the other states in which we do business. You could be liable for any and all of our obligations as if you were a general partner if a court or government agency were to determine that (i) we were conducting business in a state but had not complied with that particular state’s partnership statute; or (ii) your right to take certain actions under our partnership agreement constitute “control” of our business. For a discussion of the implications of the limitations of liability on a unitholder, please read “Our Partnership Agreement – Limited Liability.”

Unitholders may have to repay distributions that were wrongfully distributed to them.

Under certain circumstances, unitholders may have to repay amounts wrongfully distributed to them. Under Section 17-607 of the Delaware Revised Uniform Limited Partnership Act or “DRULPA,” we may not make a distribution to you if the distribution would cause our liabilities to exceed the fair value of our assets. Delaware law provides that for a period of three years from the date of the impermissible distribution, limited partners who received the distribution and who knew at the time of the distribution that it violated Delaware law will be liable to the limited partnership for the distribution amount. Transferees of common units are liable for the obligations of the transferor to make contributions to the partnership that are known to the transferee at the time of the transfer and for unknown obligations if the liabilities could be determined from our partnership agreement. Liabilities to partners on account of their partnership interest and liabilities that are non-recourse to the partnership are not counted for purposes of determining whether a distribution is permitted.

Our general partner, or any transferee holding incentive distribution rights, may elect to cause us to issue common units to it in connection with a resetting of the target distribution levels related to its incentive distribution rights, without the approval of our conflicts committee or the holders of our common units. This could result in lower distributions to holders of our common units.

Our general partner has the right, at any time when there are no subordinated units outstanding and it has received distributions on its incentive distribution rights at the highest level to which it is entitled (50%) for each of the prior four consecutive fiscal quarters, to reset the initial target distribution levels at higher levels based on our distributions at the time of the exercise of the reset election. Following a reset election, the minimum quarterly distribution will be adjusted to equal the reset minimum quarterly distribution, and the target distribution levels will be reset to correspondingly higher levels based on percentage increases above the reset minimum quarterly distribution.

If our general partner elects to reset the target distribution levels, it will be entitled to receive a number of common units. The number of common units to be issued to our general partner will be equal to that number of common units that would have entitled their holder to an average aggregate quarterly cash distribution in the prior two quarters equal to the average of the distributions to our general partner on the incentive distribution rights in such two quarters. We anticipate that our general partner would exercise this reset right in order to facilitate acquisitions or internal growth projects that would not be sufficiently accretive to cash distributions per common unit without such conversion. It is possible, however, that our general partner could exercise this reset election at a time when it is experiencing, or expects to experience, declines in the cash distributions it receives related to its incentive distribution rights and may, therefore, desire to be issued common units rather than retain the right to receive distributions based on the initial target distribution levels. This risk could be elevated if the incentive distribution rights have been transferred to a third party. As a result, a reset election may cause our common unitholders to experience a reduction in the amount of cash distributions that they would have otherwise received had we not issued new common units in connection with resetting the target distribution levels. Additionally, our general partner has the right to transfer all or any portion of the incentive distribution rights at any time, and such

38

transferee shall have the same rights as the general partner relative to resetting target distributions if our general partner concurs that the tests for resetting target distributions have been fulfilled. Please read Item 5., “Market for Registrant's Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities– Right to Reset Incentive Distribution Levels.”

NASDAQ does not require a publicly traded limited partnership like us to comply with certain of its corporate governance requirements.

Our common units are listed on the NASDAQ Global Market. NASDAQ listing rules do not require a listed limited partnership like us to have a majority of independent directors on our general partner’s board of directors or to establish a compensation committee or a nominating and corporate governance committee. We are, however, required to have an audit committee of at least three members, all of whom are required to meet the independence and experience standards established by NASDAQ and the Exchange Act. Please read Item 10., “Directors, Executive Officers and Corporate Governance – Management of Landmark Infrastructure Partners LP.”

Our partnership agreement includes exclusive forum, venue and jurisdiction provisions and a waiver of the right to a jury trial. By purchasing a common unit, a limited partner is irrevocably consenting to these provisions regarding claims, suits, actions or proceedings, submitting to the exclusive jurisdiction of Delaware courts and waiving a right to a jury trial. Our partnership agreement also provides that any unitholder bringing an unsuccessful action will be obligated to reimburse us for any costs we have incurred in connection with such unsuccessful action.

Our partnership agreement is governed by Delaware law. Our partnership agreement includes exclusive forum, venue and jurisdiction provisions designating Delaware courts as the exclusive venue for most claims, suits, actions and proceedings involving us or our officers, directors and employees. In addition, if any person brings any of the aforementioned claims, suits, actions or proceedings and such person does not obtain a judgment on the merits that substantially achieves, in substance and amount, the full remedy sought, then such person shall be obligated to reimburse us and our affiliates for all fees, costs and expenses of every kind and description, including but not limited to all reasonable attorneys’ fees and other litigation expenses, that the parties may incur in connection with such claim, suit, action or proceeding. Our partnership agreement also includes an irrevocable waiver of the right to trial by jury in all such claims, suits, actions and proceedings. By purchasing a common unit, a limited partner is irrevocably consenting to these limitations and provisions regarding claims, suits, actions or proceedings and submitting to the exclusive jurisdiction of Delaware courts. If a dispute were to arise between a limited partner and us or our officers, directors or employees, the limited partner may be required to pursue its legal remedies in Delaware which may be an inconvenient or distant location and which is considered to be a more corporate-friendly environment. These provisions may have the effect of discouraging lawsuits against us and our general partner’s directors and officers.

We will incur increased costs as a result of being a publicly traded partnership, including the cost of additional finance and accounting systems, procedures and controls in order to satisfy our public company reporting requirements.

We have limited history operating as a publicly traded partnership. As a publicly traded partnership, we will incur significant legal, accounting and other expenses. In addition, the Sarbanes-Oxley Act and related rules implemented by the SEC and NASDAQ have mandated changes in the corporate governance practices of publicly traded companies. We expect these rules and regulations to increase our legal and financial compliance costs and to make our activities more time-consuming and costly. For example, as a result of becoming a publicly traded partnership, we are required to have at least three independent directors, create an audit committee and adopt policies regarding internal controls and disclosure controls and procedures, including the preparation of reports on internal controls over financial reporting. In addition, we will incur additional costs associated with our publicly traded partnership reporting requirements. We also expect these new rules and regulations to make it more difficult and more expensive for our general partner to obtain director and officer liability insurance and possibly to result in our general partner having to accept reduced policy limits and coverage. As a result, it may be more difficult for our general partner to attract and retain qualified persons to serve on its board of directors or as executive officers.

Any failure to achieve and maintain an effective internal control environment could have a material adverse effect on our business and unit price. In addition, we may need to hire additional compliance, accounting and financial staff with appropriate public company experience and technical knowledge, and we may not be able to do so in a timely fashion. As a result, we may need to rely on outside consultants to provide these services for us until qualified personnel are hired. These obligations will increase our operating expenses and could divert our management’s attention from our operations.

We will incur increased costs as a result of managing a REIT.

On July 31, 2017, we completed our previously announced reorganization (the “Reorganization”) and transferred substantially all of our assets to the REIT Subsidiary, which we intend will qualify as a REIT, under the Code. In order to maintain its qualification as a REIT, the REIT Subsidiary must satisfy a number of requirements, including requirements regarding the ownership of its equity interests, the composition of its assets and the sources of its income. Satisfying these requirements involves monitoring various factual matters, applying highly technical and complex provisions of the Code and meeting ongoing reporting obligations, which will increase our operating expenses and could divert our management’s attention from our operations.

39

We may be adversely affected by fluctuations in currency exchange rates.

We may pursue growth opportunities in international markets where the U.S. dollar is not the denominated currency. The ownership of investments located outside of the United States subjects us to risk from fluctuations in exchange rates between foreign currencies and the U.S. dollar. A significant change in the value of currencies in countries where we have a significant investment may have a materially adverse effect on our financial position, debt covenant ratios, results of operations and cash flow.

We may attempt to manage the impact of foreign currency exchange rate changes through the use of derivative contracts or other methods. However, no amount of hedging activity can fully insulate us from the risks associated with changes in foreign currency exchange rates, and the failure to hedge effectively against foreign currency exchange rate risk, if we choose to engage in such activities, could materially adversely affect our results of operations and financial condition.

Increased regulatory oversight, changes in the method pursuant to which the London Inter Bank Offering Rate (“LIBOR”) rates are determined and potential phasing out of LIBOR after 2021 may adversely affect interest expense related to outstanding debt and swap agreements.

Regulators and law enforcement agencies in the U.K. and elsewhere are conducting civil and criminal investigations into whether the banks that contribute to the British Bankers’ Association (the “BBA”) in connection with the calculation of daily LIBOR may have been under-reporting or otherwise manipulating or attempting to manipulate LIBOR. A number of BBA member banks have entered into settlements with their regulators and law enforcement agencies with respect to this alleged manipulation of LIBOR. On July 27, 2017, the Financial Conduct Authority (the “FCA”) announced that it will no longer persuade or compel banks to submit LIBOR rates after 2021 (the “FCA Announcement”). Based on the FCA Announcement, it appears likely that LIBOR will be discontinued or modified by 2021. As a result, the Federal Reserve Board and the Federal Reserve Bank of New York organized the Alternative Reference Rates Committee (the “ARRC”) which identified the Secured Overnight Financing Rate (the “SOFR”) as its preferred alternative to USD-LIBOR in derivatives and other financial contracts. The Partnership is not able to predict when LIBOR will cease to be available or when there will be sufficient liquidity in the SOFR markets. Any changes adopted by FCA or other governing bodies in the method used for determining LIBOR may result in a sudden or prolonged increase or decrease in reported LIBOR. If that were to occur, our interest payments could change. In addition, uncertainty about the extent and manner of future changes may result in interest rates and/or payments that are higher or lower than if LIBOR were to remain available in its current form.

The Partnership has agreements that are indexed to LIBOR and is monitoring and evaluating the related risks, which include interest on loans and valuation of derivative instruments. These risks arise in connection with transitioning contracts to a new alternative rate, including any resulting value transfer that may occur. The value of loans or derivative instruments tied to LIBOR could also be impacted if LIBOR is limited or discontinued. For some instruments, the method of transitioning to an alternative rate may be challenging, as they may require negotiation with the respective counterparty.

If a contract is not transitioned to an alternative rate and LIBOR is discontinued, the impact on our contracts is likely to vary by contract. If LIBOR is discontinued or if the methods of calculating LIBOR change from their current form, interest rates on our current or future indebtedness may be adversely affected.

While we expect LIBOR to be available in substantially its current form until the end of 2021, it is possible that LIBOR will become unavailable prior to that point. This could result, for example, if sufficient banks decline to make submissions to the LIBOR administrator. In that case, the risks associated with the transition to an alternative reference rate will be accelerated and magnified. Our revolving credit facility contains fallback language generally consistent with the ARRC’s amendment approach, which provides a streamlined amendment approach for negotiating a benchmark replacement and introduces clarity with respect to the fallback trigger events and an adjustment to be applied to the successor rate. We continue to monitor developments by the ARRC and the potential impact of LIBOR changes on our business. As such, the future of LIBOR and potential alternatives at this time remains uncertain.

Risks Related to Preferred Units

The market price of our Preferred Units may be adversely affected by the future issuance and sale of additional Preferred Units, including pursuant to the sales agreement, or by our announcement that such issuances and sales may occur.

We cannot predict the size of future issuances or sales of our Preferred Units, including those made pursuant to the sales agreement with any of our sales agents or in connection with future acquisitions or capital raising activities, or the effect, if any, that such issuances or sales may have on the market price of our Preferred Units. In addition, the sales agents will not engage in any transactions that stabilize the price of our Preferred Units. The issuance and sale of substantial amounts of Preferred Units, including issuances and sales pursuant to the sales agreement, or announcement that such issuances and sales may occur, could adversely affect the market price of our Preferred Units.

40

The Preferred Units represent perpetual equity interests in us, and investors should not expect us to redeem the Preferred Units on the date the Preferred Units become redeemable by us or on any particular date afterwards.

The Series A and Series B Preferred Units represent perpetual equity interests in us, and they have no maturity or mandatory redemption date and are not redeemable at the option of investors under any circumstances. As a result, unlike our indebtedness, the Preferred Units will not give rise to a claim for payment of a principal amount at a particular date. Instead, the Series A and Series B Preferred Units may be redeemed by us at our option in the event of a change of control or at any time on or after April 4, 2021 for the Series A Preferred Units and on August 8, 2021 for the Series B Preferred Units, in whole or in part, out of funds legally available for such redemption, at a redemption price of $25.00 per unit plus an amount equal to all accumulated and unpaid distributions thereon to the date of redemption, whether or not declared. Any decision we may make at any time to redeem the Series A and Series B Preferred Units will depend upon, among other things, our evaluation of our capital position and general market conditions at that time.

As a result, holders of the Series A and Series B Preferred Units may be required to bear the financial risks of an investment in the Series A and Series B Preferred Units for an indefinite period of time. The Series A Preferred Units rank in parity to the Series B Preferred Units and Series C Preferred Units with respect to distributions and distributions upon a liquidation event. In addition, the Preferred Units will rank junior to all our current and future indebtedness (including indebtedness outstanding under our revolving credit facility) and other liabilities. The Preferred Units will also rank junior to any other senior securities we may issue in the future with respect to assets available to satisfy claims against us.

The Preferred Units have not been rated.

We have not sought to obtain a rating for the Preferred Units, and the Preferred Units may never be rated. It is possible, however, that one or more rating agencies might independently determine to assign a rating to the Preferred Units or that we may elect to obtain a rating of the Preferred Units in the future. In addition, we may elect to issue other securities for which we may seek to obtain a rating. If any ratings are assigned to the Preferred Units in the future or if we issue other securities with a rating, such ratings, if they are lower than market expectations or are subsequently lowered or withdrawn, could adversely affect the market for or the market value of the Preferred Units. Ratings only reflect the views of the issuing rating agency or agencies and such ratings could at any time be revised downward or withdrawn entirely at the discretion of the issuing rating agency. A rating is not a recommendation to purchase, sell or hold any particular security, including the Preferred Units. Ratings do not reflect market prices or suitability of a security for a particular investor and any future rating of the Preferred Units may not reflect all risks related to us and our business, or the structure or market value of the Preferred Units.

We distribute all of our available cash to our common unitholders and are not required to accumulate cash for the purpose of meeting our future obligations to holders of the Preferred Units, which may limit the cash available to make distributions on the Preferred Units.

Our Partnership Agreement requires us to distribute all of our "available cash" each quarter to our common unitholders. "Available cash" is defined in our Partnership Agreement, and it generally means, for each fiscal quarter, all cash and cash equivalents on the date of determination of available cash for that quarter, less the amount of any cash reserves established by our general partner to:

• provide for the proper conduct of our business;

• comply with applicable law, the terms of any of our debt instruments or other agreements;

• provide funds to make payments on the Series A Preferred Units, the Series B Preferred Units or the Series C Preferred Units; or

• provide funds for distributions to our unitholders and to our general partner for any one or more of the next four quarters.

As a result, we do not expect to accumulate significant amounts of cash. Depending on the timing and amount of our cash distributions, these distributions could significantly reduce the cash available to us in subsequent periods to make payments on the Preferred Units.

The Preferred Units are subordinated to our existing and future debt obligations, and your interests could be diluted by the issuance of additional units, including additional Preferred Units, and by other transactions.

The Preferred Units are subordinated to all of our existing and future indebtedness (including indebtedness outstanding under our revolving credit facility). As of December 31, 2020, our total debt was approximately $493.9 million, and we had the ability to borrow an additional $235.8 million (including standby letter of credit arrangements of $5.8 million) under our revolving credit facility, subject to certain limitations. We may incur additional debt under our revolving credit facility or future debt agreements. The payment of principal and interest on our debt reduces cash available for distribution to us and on our units, including the Preferred Units.

The issuance of additional units on a parity with or senior to the Preferred Units would dilute the interests of the holders of the Preferred Units, and any issuance of parity securities or senior securities or additional indebtedness could affect our ability to pay distributions on, redeem or pay the liquidation preference on the Preferred Units. Only the change of control conversion right relating to the Preferred Units protects the holders of the Preferred Units in the event of a highly leveraged or other transaction, including a merger or the sale, lease or conveyance of all or substantially all our assets or business, which might adversely affect the holders of the Preferred Units.

41

As a holder of Preferred Units you have extremely limited voting rights.

Your voting rights as a holder of Preferred Units is extremely limited. Our common units are the only class of our partnership interests carrying full voting rights. Holders of the Preferred Units generally have no voting rights.

The lack of a fixed redemption date for the Preferred Units will increase your reliance on the secondary market for liquidity purposes.

Because the Preferred Units have no stated maturity date, investors seeking liquidity will be limited to selling their Preferred Units in the secondary market absent redemption by us. We have listed the Preferred Units on NASDAQ, but an active trading market on the NASDAQ for the Series A, Series B and Series C Preferred Units may not develop or, even if it develops, may not last, in which case the trading price of the Preferred Units could be adversely affected and your ability to transfer your Preferred Units will be limited. If an active trading market does develop on the NASDAQ, the Preferred Units may trade at prices lower than the offering price. The trading price of the Preferred Units depends on many factors, including:

• prevailing interest rates;

• the market for similar securities;

• general economic and financial market conditions;

• our issuance of debt or other preferred equity securities; and

• our financial condition and results of operations.

Market interest rates may adversely affect the value of the Preferred Units.

One of the factors that will influence the price of the Preferred Units will be the distribution yield on the Preferred Units (as a percentage of the price of the Preferred Units) relative to market interest rates. An increase in market interest rates, which are currently at low levels relative to historical rates, may lead prospective purchasers of the Preferred Units to expect a higher distribution yield, and higher interest rates would likely increase our borrowing costs and potentially decrease funds available for distribution. Accordingly, higher market interest rates could cause the market price of the Preferred Units to decrease.

Change of control conversion rights may make it more difficult for a party to acquire us or discourage a party from acquiring us.

The change of control conversion feature of the Preferred Units may have the effect of discouraging a third party from making an acquisition proposal for us or of delaying, deferring or preventing certain of our change of control transactions under circumstances that otherwise could provide the holders of our common units and Preferred Units with the opportunity to realize a premium over the then-current market price of such equity securities or that unitholders may otherwise believe is in their best interests.

Holders of Preferred Units may have liability to repay distributions.

Under certain circumstances, holders of the Preferred Units may have to repay amounts wrongfully returned or distributed to them. Under Section 17-607 of the Delaware Revised Uniform Limited Partnership Act, we may not make a distribution if the distribution would cause our liabilities to exceed the fair value of our assets. Liabilities to partners on account of their partnership interests and liabilities that are non-recourse to the partnership are not counted for purposes of determining whether a distribution is permitted.

Delaware law provides that for a period of three years from the date of an impermissible distribution, limited partners who received the distribution and who knew at the time of the distribution that it violated Delaware law will be liable to the limited partnership for the distribution amount. A purchaser of Preferred Units who becomes a limited partner is liable for the obligations of the transferring limited partner to make contributions to the Partnership that are known to such purchaser of units at the time it became a limited partner and for unknown obligations if the liabilities could be determined from our Partnership Agreement.

42

The Series C preferred units represent perpetual equity interests in us, and investors should not expect us to redeem the Series C preferred units on the date the Series C preferred units become redeemable by us or on any particular date afterwards.

The Series C Preferred Units represent perpetual equity interests in us, and they have no maturity or mandatory redemption date. As a result, unlike our indebtedness, the Series C Preferred Units will generally not give rise to a claim for payment of a principal amount at a particular date. Instead, the Series C Preferred Units may be redeemed by us at our option at any time on or after May 20, 2025, in whole or in part, out of funds legally available for such redemption, at a redemption price of $25.00 per Series C Preferred Unit plus an amount equal to all accumulated and unpaid distributions thereon to the date of redemption, whether or not declared, or at the holder’s option. In addition, if holders of Series C Preferred Units choose not to exercise the special conversion right in connection with a fundamental change as described above, we will have the option to redeem our Series C Preferred Units, in whole but not in part, within 90 days after the last day of the related fundamental change conversion period for cash at a price of $25.00 per Series C Preferred Unit, plus accrued and unpaid distributions (whether or not earned or declared) to, but not including, the redemption date. Any decision we may make at any time to redeem the Series C Preferred Units will depend upon, among other things, our evaluation of our capital position and general market conditions at that time.

As a result, holders of the Series C Preferred Units may be required to bear the financial risks of an investment in the Series C Preferred Units for an indefinite period of time, unless they choose to convert their Series C Preferred Unit to common units. The Series C Preferred Units rank in parity to our existing Series A and Series B Preferred Units with respect to distributions and distributions upon a liquidation event. In addition, the Series C Preferred Units will rank junior to all our current and future indebtedness, and other liabilities. The Series C Preferred Units will also rank junior to any other senior securities we may issue in the future with respect to assets available to satisfy claims against us.

Until May 15, 2025, the distribution payable on the Series C Preferred Units will vary based on market interest rates.

Until May 15, 2025, the Series C Preferred Units will, subject to the LIBOR floor discussed in clause (i), have a floating distribution rate set each quarterly distribution period at a percentage of the $25.00 liquidation preference equal to the greater of (i) 7.00% per annum, and (ii) a floating rate of the then-current three-month LIBOR plus a spread of 4.698%. The per annum distribution rate that is determined on the relevant determination date will apply to the entire quarterly distribution period following such determination date even if LIBOR increases during that period. As a result, holders of Series C Preferred Units will be subject to risks associated with fluctuation in interest rates and the possibility that holders will receive distributions that are lower than expected. We have no control over a number of factors, including economic, financial and political events, that impact market fluctuations in interest rates, which have in the past and may in the future experience volatility.

Increased regulatory oversight, changes in the method pursuant to which the LIBOR rates are determined and potential phasing out of LIBOR after 2021 may adversely affect the value of the Series C Preferred Units.

Regulators and law enforcement agencies in the U.K. and elsewhere are conducting civil and criminal investigations into whether the banks that contribute to the BBA in connection with the calculation of daily LIBOR may have been under-reporting or otherwise manipulating or attempting to manipulate LIBOR. A number of BBA member banks have entered into settlements with their regulators and law enforcement agencies with respect to this alleged manipulation of LIBOR. On July 27, 2017, the FCA announced that it will no longer persuade or compel banks to submit LIBOR rates after 2021 (the “FCA Announcement”). Based on the FCA Announcement, it appears likely that LIBOR will be discontinued or modified by 2021.

Under the terms of the Series C Preferred Units, the floating component of the distribution rate on the Series C Preferred Units for each distribution period during the floating rate period is based on the three-month LIBOR. If the calculation agent is unable to determine the three-month LIBOR based on screen-based reporting of that base rate, and if the calculation agent is also unable to obtain suitable quotations for the three-month LIBOR from reference banks, then the calculation agent will determine the three-month LIBOR after consulting such sources as it deems comparable or reasonable. In addition, if the calculation agent determines that the three-month LIBOR has been discontinued, then the calculation agent will determine whether to calculate the relevant distribution rate using a substitute or successor base rate that it has determined in its sole discretion is most comparable to the three-month LIBOR, provided that if the calculation agent determines there is an industry-accepted successor base rate, the calculation agent will use that successor base rate. In such instances, the calculation agent in its sole discretion may determine what business day convention to use, the definition of business day, the distribution determination date to be used and any other relevant methodology for calculating such substitute or successor base rate, including any adjustment factor needed to make such substitute or successor base rate comparable to the three-month LIBOR, in a manner that is consistent with industry-accepted practices for such substitute or successor base rate, with respect to the calculation of distributions on the Series C Preferred Units during the floating rate period. Any of the foregoing determinations or actions by the calculation agent could result in adverse consequences to the applicable distribution rate on the Series C Preferred Units during the floating rate period, which could adversely affect the return on, value of and market for the Series C Preferred Units.

The increased conversion rate for the Series C Preferred Units triggered by a fundamental change could discourage a potential acquiror.

The increased conversion rate triggered by a fundamental change could discourage a potential acquirer, including potential acquirors that otherwise seek a transaction with us that would be attractive to holders.

43

A change in control with respect to the Partnership may not constitute a fundamental change for the purpose of the Series C Preferred Units.

The Series C Preferred Units contain no covenants or other provisions to afford protection in the event of a change in control with respect to the Partnership, except upon the occurrence of a fundamental change. However, the term “fundamental change” is limited and may not include every change-in-control event that might cause the market price of the Series C Preferred Units to decline. As a result, rights of holders under the Series C Preferred Units may not preserve the value of the Series C Preferred Units in the event of a change in control with respect to us. In addition, any change in control with respect to the Partnership may negatively affect the liquidity, value or volatility of our common units, negatively impacting the value of the Series C Preferred Units.

The adjustment of the conversion rate for the Series C Preferred Units in respect of conversions during a fundamental change conversion period may not adequately compensate holders of Series C Preferred Units.

If a fundamental change occurs, holders of Series C Preferred Units will have the right to convert some or all of their Series C Preferred Units during the fundamental change conversion period into the greater of:

• a number of common units in our Partnership Agreement; and

• a number of common units equal to the lesser of (a) the liquidation preference divided by the market value of our common units on the effective date of such fundamental change and (b) 11.13 (subject to adjustment).

The adjustment to the conversion rate described above may not wholly compensate holders of Series C Preferred Units for the lost option value of their Series C Preferred Units or the lost liquidation preference. Upon a conversion during a fundamental change conversion period, holders of Series C Preferred Units may receive value that is less than the liquidation preference of their Series C Preferred Units.

Our obligation to deliver the make-whole premium or to adjust the conversion rate in respect of conversions during a fundamental change conversion period could be considered a penalty, in which case the enforceability thereof would be subject to general principles of reasonableness, as applied to such payments.

Holders of Series C Preferred Units will have no rights with respect to the underlying common units until they convert their Series C Preferred Units, but holders of Series C Preferred Units may be adversely affected by certain changes made with respect to our common units.

Holders of Series C Preferred Units will have no rights with respect to our common units underlying their Series C Preferred Units, including voting rights, rights to respond to common unit tender offers, if any, and rights to receive distributions or other distributions on our common units, if any (in each case, other than through a conversion rate adjustment), prior to the conversion date with respect to a conversion of Series C Preferred Units, but an investment in our Series C Preferred Units may be negatively affected by these events. Upon conversion, holders of Series C Preferred Units will be entitled to exercise the rights of a holder of common units only as to matters for which the relevant record date occurs on or after the conversion date. For example, in the event that an amendment is proposed to our Partnership Agreement requiring unitholder approval and the record date for determining the unitholders of record entitled to vote on the amendment occurs prior to the conversion date, holders of Series C Preferred Units will not be entitled to vote on the amendment, although they will nevertheless be subject to any changes in the powers, preferences or special rights of our common units.

Future sales of our common units in the public market could lower the market price for our common units and adversely affect the trading price of the Series C Preferred Units.

In the future, we may sell additional common units to raise capital. We cannot predict the size of future issuances or the effect, if any, that they may have on the market price for our common units. The issuance and sale of substantial amounts of common units, or the perception that such issuances and sales may occur, could adversely affect the trading price of the Series C Preferred Units and the market price of our common units and impair our ability to raise capital through the sale of additional equity securities.

The conversion rate of the Series C Preferred Units may not be adjusted for all dilutive events.

The number of common units that holders of Series C Preferred Units are entitled to receive upon conversion of Series C Preferred Units is subject to adjustment for certain specified events, including, but not limited to, the issuance of certain unit distributions on our common units, the issuance of certain rights or warrants, subdivisions, combinations, distributions of equity securities, indebtedness, or assets, certain cash distributions and certain issuer tender or exchange offers. However, the conversion rate may not be adjusted for other events, such as offerings of our common units or securities convertible into common units (other than as set forth in our partnership) for cash or in connection with acquisitions, which may adversely affect the market price of our common units. Further, if any of these other events adversely affects the market price of our common units, we expect it to also adversely affect the market price of the Series C Preferred Units. In addition, the terms of our Series C Preferred Units do not restrict our ability to offer common units or securities convertible into common units in the future or to engage in other transactions that could dilute our common units. We have no obligation to consider the interests of the holders of our Series C Preferred

44

Units in engaging in any such offering or transaction. If we issue additional common units, those issuances may materially and adversely affect the market price of our common units and, in turn, those issuances may adversely affect the trading price of the Series C Preferred Units.

Recent regulatory actions may adversely affect the trading price and liquidity of the Series C Preferred Units.

Holders of Series C Preferred Units may employ, or seek to employ, a convertible arbitrage strategy with respect to the Series C Preferred Units. Holders that employ a convertible arbitrage strategy with respect to convertible securities typically implement that strategy by selling short the security underlying the convertible security (i.e., our common units in the case of the Series C Preferred Units) and dynamically adjusting their short position while they hold the convertible security. Holders may also implement this strategy by entering into swaps on the underlying security in lieu of or in addition to short selling the underlying security. As a result, any specific rules regulating equity swaps or short selling of securities or other governmental action that interferes with the ability of market participants to effect short sales or equity swaps with respect to our common units could adversely affect the ability of holders of the Series C Preferred Units to conduct the convertible arbitrage strategy that we believe they may employ, or seek to employ, with respect to the Series C Preferred Units. This could, in turn, adversely affect the trading price and liquidity of the Series C Preferred Units. 

The SEC and other regulatory and self-regulatory authorities have implemented various rules and taken certain actions, and may in the future adopt additional rules and take other actions, that may impact those engaging in short selling activity involving equity securities (including our common units). These rules and actions include Rule 201 of SEC Regulation SHO, the adoption by the Financial Industry Regulatory Authority, Inc. and the national securities exchanges of a “Limit Up-Limit Down” program, the imposition of market-wide circuit breakers that halt trading of securities for certain periods following specific market declines, and the implementation of certain regulatory reforms required by the Dodd-Frank Wall Street Reform and Consumer Protection Act. Any governmental or regulatory action that restricts the ability of holders of the Series C Preferred Units to effect short sales of our common units or enter into swaps on our common units could adversely affect the trading price and the liquidity of the Series C Preferred Units.

In addition, if holders of Series C Preferred Units seeking to employ a convertible arbitrage strategy are unable to borrow or enter into swaps on our common units, in each case on commercially reasonable terms, the trading price and liquidity of the Series C Preferred Units may be adversely affected.

Holders of Series C Preferred Units may have liability to repay distributions.

Under certain circumstances, holders of the Series C Preferred Units may have to repay amounts wrongfully returned or distributed to them. Under Section 17-607 of the Delaware Revised Uniform Limited Partnership Act, we may not make a distribution if the distribution would cause our liabilities to exceed the fair value of our assets. Liabilities to partners on account of their partnership interests and liabilities that are non-recourse to the partnership are not counted for purposes of determining whether a distribution is permitted.

Delaware law provides that for a period of three years from the date of an impermissible distribution, limited partners who received the distribution and who knew at the time of the distribution that it violated Delaware law will be liable to the limited partnership for the distribution amount. A purchaser of Series C Preferred Units who becomes a limited partner is liable for the obligations of the transferring limited partner to make contributions to the Partnership that are known to such purchaser of units at the time it became a limited partner and for unknown obligations if the liabilities could be determined from our Partnership Agreement.

Upon a conversion in connection with a fundamental change under the Series C Preferred Units, holders of Series C Preferred Units may receive consideration worth less than the $25.00 liquidation preference per Series C Preferred Unit, plus any accumulated and unpaid distributions thereon.

If a “fundamental change” under the Series C Preferred Units occurs and regardless of the price paid (or deemed paid) per common unit in such fundamental change, then holders of the Series C Preferred Units will have the right to convert their units at an adjusted conversion rate that is designed to increase the value of the common units deliverable upon conversion of each Series C Preferred Unit to the $25.00 liquidation preference per Series C Preferred Unit, plus any accumulated and unpaid distributions thereon. However, if the price paid (or deemed paid) in such fundamental change is less than a certain amount, holders will receive a number of common units worth less than the $25.00 liquidation preference per Series C Preferred Unit, plus any accumulated and unpaid distributions thereon. Holders of Series C Preferred Units will have no claim against us for the difference between the value of the consideration you receive upon a conversion in connection with a fundamental change and the $25.00 liquidation preference per Series C Preferred Unit, plus any accumulated and unpaid distributions thereon.

We may be unable to redeem the Series C Preferred Units upon its redemption at the option of the holder.

We are required to redeem a holder’s Series C Preferred Units following the investor’s exercise of its redemption right. If we do not have sufficient funds available to fulfill these obligations, we may be unable to satisfy the holder’s put right.

45

The Series C Preferred Units may adversely affect the market price of our common units.

The market price of our common units is likely to be influenced by the Series C Preferred Units. For example, the market price of our common units could become more volatile and could be depressed by:

• investors’ anticipation of the potential resale in the market of a substantial number of additional common units received upon conversion of the Series C Preferred Units;

• possible sales of our common units by investors who view the Series C Preferred Units as a more attractive means of equity participation in us than owning our common units; and

• hedging or arbitrage trading activity that may develop involving the Series C Preferred Units and our common units.

Tax Risks

Our tax treatment depends on our status as a partnership for federal income tax purposes. If the IRS were to treat us as a corporation for federal income tax purposes, which would subject us to entity-level taxation, or if we were otherwise subjected to a material amount of additional entity-level taxation, then our distributable cash flow to our unitholders would be substantially reduced.

The anticipated after-tax economic benefit of an investment in our common units depends largely on our being treated as a partnership for federal income tax purposes. We have not requested a ruling from the IRS with respect to our treatment as a partnership for federal income tax purposes.

Despite the fact that we are a limited partnership under Delaware law, it is possible in certain circumstances for a partnership such as ours to be treated as a corporation for federal income tax purposes. A change in our business, a change in current law or our failure to satisfy the requirements under the Code could cause us to be treated as a corporation for federal income tax purposes or otherwise subject us to taxation as an entity.

If we were treated as a corporation for federal income tax purposes, we would pay federal income tax on our taxable income at the corporate tax rate, which is currently a flat rate of 21% (and a maximum of 35% for our tax years beginning prior to January 1, 2018), and would likely pay state and local income tax at varying rates. Distributions would generally be taxed again as corporate dividends (to the extent of our current and accumulated earnings and profits), and no income, gains, losses, deductions, or credits would flow through to our unitholders. Because a tax would be imposed upon us as a corporation, our distributable cash flow would be substantially reduced and we might need to raise funds to pay such corporate level tax. In addition, changes in current state law may subject us to additional entity-level taxation by individual states. Because of state budget deficits and other reasons, several states are evaluating ways to subject partnerships to entity-level taxation through the imposition of state income, franchise and other forms of taxation. Imposition of any such taxes may substantially reduce the cash available for distribution to our unitholders. Therefore, if we were treated as a corporation for federal income tax purposes or otherwise subjected to a material amount of entity-level taxation, there would be a material reduction in the anticipated cash flow and after-tax return to our unitholders, likely causing a substantial reduction in the value of our common units.

Our partnership agreement provides that, if a law is enacted or existing law is modified or interpreted in a manner that subjects us to taxation as a corporation or otherwise subjects us to entity-level taxation for federal, state or local income tax purposes, the minimum quarterly distribution amount and the target distribution levels may be adjusted to reflect the impact of that law on us.

The tax treatment of REITs, publicly traded partnerships or an investment in our common units could be subject to legislative, judicial or administrative changes and differing interpretations, possibly on a retroactive basis.

As described above, we completed the Reorganization in 2017 and transferred substantially all of our assets to the REIT Subsidiary. Dividends from the REIT Subsidiary will generally be publicly traded partnership qualifying income to us and taxable to our unitholders at ordinary income rates. In October 2016, we also formed Landmark Infrastructure REIT LLC, a Delaware limited liability company, that is now a subsidiary of the REIT Subsidiary. In the future, we may own and operate other assets in the REIT Subsidiary.

The present federal income tax treatment of REITs, publicly traded partnerships, including us, or an investment in our common units may be modified by administrative, legislative or judicial interpretation at any time. For example, members of Congress and the President have periodically considered substantive changes to the existing federal income tax laws that would affect the tax treatment of certain publicly traded partnerships, including the elimination of partnership tax treatment for publicly traded partnerships. Any modification to the federal income tax laws and interpretations thereof may or may not be retroactively applied and could make it more difficult or impossible for us to satisfy the requirements of the exception pursuant to which we are treated as a partnership for federal income tax purposes or for the REIT Subsidiary to qualify as a REIT. We are unable to predict whether any such changes will ultimately be enacted. However, it is possible that a change in law could affect us or the REIT Subsidiary, and any such changes could negatively impact the value of an investment in our common units.

46

Our unitholders’ share of our income is taxable to them for federal income tax purposes even if they do not receive any cash distributions from us.

Because a unitholder is treated as a partner to whom we allocate taxable income that could be different in amount than the cash we distribute, a unitholder’s allocable share of our taxable income is taxable to it, which may require the payment of federal income taxes and, in some cases, state and local income taxes, on its share of our taxable income even if it receives no cash distributions from us. Our unitholders may not receive cash distributions from us equal to their share of our taxable income or even equal to the actual tax liability that results from that income.

If the IRS contests the federal income tax positions we take, the market for our common units may be adversely impacted and the cost of any IRS contest will reduce our distributable cash flow to our unitholders.

We have not requested a ruling from the IRS with respect to our treatment as a partnership for federal income tax purposes. We intend to furnish to each unitholder, within 90 days after the close of each calendar year, specific tax information, including a Schedule K-1, which describes his share of our income, gain, loss and deduction for our preceding taxable year. In preparing this information we will take various accounting and reporting positions. The IRS may adopt positions that differ from the positions we take, and the IRS’s positions may ultimately be sustained. It may be necessary to resort to administrative or court proceedings to sustain some or all of the positions we take and such positions may not ultimately be sustained. A court may not agree with some or all of the positions we take. Any contest with the IRS, and the outcome of any IRS contest, may have a materially adverse impact on the market for our common units and the price at which they trade. In addition, our costs of any contest with the IRS will be borne indirectly by our unitholders because the costs will reduce our distributable cash flow.

If the IRS makes audit adjustments to our income tax returns for tax years beginning after December 31, 2017, it may assess and collect any taxes (including any applicable penalties and interest) resulting from such audit adjustment directly from us, in which case our cash available for distribution to our unitholders might be substantially reduced.

Pursuant to the Bipartisan Budget Act of 2015, for tax years beginning after December 31, 2017, if the IRS makes audit adjustments to our income tax returns, it may assess and collect any taxes (including any applicable penalties and interest) resulting from such audit adjustments directly from us. Generally, we expect to elect to have our unitholders take such audit adjustment into account in accordance with their interests in us during the tax year under audit, but there can be no assurance that such election will be effective in all circumstances. If we are unable to have our unitholders take such audit adjustments into account in accordance with their interests in us during the tax year under audit, our current unitholders may bear the tax liability resulting from such audit adjustment, even if such unitholders did not own units in us during the tax year under audit. If, as a result of any such audit adjustment, we are required to make payments of taxes, penalties and interest, our cash available for distribution to our unitholders might be substantially reduced. These rules are not applicable to us for tax years beginning on or prior to December 31, 2017.

Tax gain or loss on the disposition of our common units could be more or less than expected.

If our unitholders sell common units, they will recognize a gain or loss for federal income tax purposes equal to the difference between the amount realized and their tax basis in those common units. A unitholder’s amount realized on his sale of common units will generally equal the amount of cash (or the fair market value of any property) he receives plus his allocable share of our nonrecourse liabilities. Because distributions in excess of their allocable share of our net taxable income decrease their tax basis in their common units, the amount, if any, of such prior excess distributions with respect to the common units a unitholder sells will, in effect, become taxable income to the unitholder if he sells such common units at a price greater than his tax basis in those common units, even if the price received is less than his original cost. Furthermore, a substantial portion of the amount realized on any sale of a unitholder’s common units, whether or not representing gain, may be taxed as ordinary income due to potential recapture items, including depreciation recapture. In addition, because the amount realized includes a unitholder’s share of our nonrecourse liabilities, a unitholder that sells common units may incur a tax liability in excess of the amount of cash received from the sale.

Tax-exempt entities and non-U.S. persons face unique tax issues from owning our common units that may result in adverse tax consequences to them.

Investment in common units by tax-exempt entities, such as employee benefit plans and individual retirement accounts (known as IRAs), and non-U.S. persons raises issues unique to them. For example, distributions to non-U.S. persons are reduced by withholding taxes at the highest applicable effective tax rate, and non-U.S. persons are required to file federal income tax returns and pay tax on their share of our taxable income.

We may be required to deduct and withhold amounts from distributions to foreign unitholders related to withholding tax obligations arising from the sale or disposition of our units by foreign unitholders.

Upon the sale, exchange or other disposition of a unit by a foreign unitholder, the transferee is generally required to withhold 10% of the amount realized on such sale, exchange or other disposition if any portion of the gain on such sale, exchange or other disposition would be treated as effectively connected with a U.S. trade or business. The U.S. Department of the Treasury and the IRS have recently issued final regulations providing guidance on the application of these rules for transfers of certain publicly traded partnership interests, including transfers of our units.

47

Under these regulations, the “amount realized” on a transfer of our units will generally be the amount of gross proceeds paid to the broker effecting the applicable transfer on behalf of the transferor, and such broker will generally be responsible for the relevant withholding obligations. Distributions to foreign persons may also be subject to additional withholding under these rules to the extent a portion of a distribution is attributable to an amount in excess of our cumulative net income that has not previously been distributed. The U.S. Department of the Treasury and the IRS have provided that these rules will generally not apply to transfers of, or distributions on, our units occurring before January 1, 2022.

We treat each purchaser of common units as having the same tax benefits without regard to the actual common units purchased. The IRS may challenge this treatment, which could adversely affect the value of the common units.

Because we cannot match transferors and transferees of common units and because of other reasons, we have adopted depreciation and amortization positions that may not conform to all aspects of existing Treasury regulations. A successful IRS challenge to those positions could adversely affect the amount of tax benefits available to you. It also could affect the timing of these tax benefits or the amount of gain from your sale of common units and could have a negative impact on the value of our common units or result in audit adjustments to your tax returns.

We prorate our items of income, gain, loss and deduction between transferors and transferees of our units each month based upon the ownership of our units on the first business day of each month, instead of on the basis of the date a particular unit is transferred. The IRS may challenge aspects of our proration method, and, if successful, we would be required to change the allocation of items of income, gain, loss and deduction among our unitholders.

We prorate our items of income, gain, loss and deduction between transferors and transferees of our units each month based upon the ownership of our units on the first business day of each month, instead of on the basis of the date a particular unit is transferred. The U.S. Department of Treasury and the IRS have issued Treasury regulations that permit publicly traded partnerships to use a monthly simplifying convention that is similar to ours, but they do not specifically authorize all aspects of the proration method we have adopted. If the IRS were to successfully challenge this method, we could be required to change the allocation of items of income, gain, loss and deduction among our unitholders. 

A unitholder whose common units are loaned to a “short seller” to effect a short sale of common units may be considered as having disposed of those common units. If so, he would no longer be treated for federal income tax purposes as a partner with respect to those common units during the period of the loan and may recognize gain or loss from the disposition.

Because a unitholder whose common units are loaned to a “short seller” to effect a short sale of common units may be considered as having disposed of the loaned common units, he may no longer be treated for federal income tax purposes as a partner with respect to those common units during the period of the loan to the short seller and the unitholder may recognize gain or loss from such disposition. Moreover, during the period of the loan to the short seller, any of our income, gain, loss or deduction with respect to those common units may not be reportable by the unitholder and any cash distributions received by the unitholder as to those common units could be fully taxable as ordinary income.

Treatment of distributions on our Preferred Units is uncertain.

The tax treatment of distributions on our Preferred Units is uncertain. We will treat the holders of Preferred Units as partners for tax purposes and will treat distributions paid to holders of Preferred Units as being made to such holders in their capacity as partners. If the Preferred Units are not partnership interests, they would likely constitute indebtedness for U.S. federal income tax purposes and distributions to the holders of Preferred Units would constitute ordinary interest income to holders of Preferred Units. If Preferred Units are treated as partnership interests, but distributions to holders of Preferred Units are not treated as being made to such holders in their capacity as partners, then these distributions would likely be treated as guaranteed payments for the use of capital. Guaranteed payments would generally be taxable to the recipient as ordinary income, and a recipient could recognize taxable income from the accrual of such a guaranteed payment even in the absence of a contemporaneous distribution. Holders of Preferred Units should consult their tax advisors with respect to the consequences of owning our Preferred Units.

U.S. Tax Risks Relating to Our REIT Subsidiary

Ownership limitations and transfer restrictions may restrict or prevent you from engaging in certain transfers of our common units, preferred units, or other partnership interests.

As described above, we completed the Reorganization in 2017 and transferred substantially all of our assets to the REIT Subsidiary. In connection with the Reorganization, we amended our partnership agreement to adopt ownership limitations that may restrict or prevent you from engaging in certain transfers of our common units, preferred units or other partnership interests. Pursuant to this amendment, subject to certain exceptions, no person or entity may actually or beneficially own, or be deemed to own by virtue of the applicable constructive ownership provisions of the Code, more than 9.8% of the interests in the Partnership’s capital or profits, or in any class or series of outstanding partnership interests (determined based on the value or number of units of such class or series, whichever is more restrictive), including our common units and our preferred units. If you own or transfer partnership interests in a manner that would violate the ownership limit, or prevent the REIT Subsidiary from qualifying as a REIT under the Code, then those partnership interests instead will be transferred to a trust for the benefit of a charitable beneficiary and will be either redeemed by us or sold to a person whose ownership of the partnership interests will not violate the ownership limit.

48

If this transfer to a trust fails to prevent such a violation or fails to permit the REIT Subsidiary’s qualification as a REIT, then the initial intended transfer will be null and void from the outset. The intended transferee of those partnership interests will be deemed never to have owned the partnership interests. Anyone who acquires common units, preferred units, or other partnership interests in violation of the ownership limit or the other restrictions on transfer bears the risk of suffering a financial loss when the common units, preferred units, or other partnership interests are redeemed or sold if the market price of our common units, preferred units, or other partnership interests falls between the date of purchase and the date of redemption or sale.

Ownership limitations could have the effect of delaying, deferring or preventing a takeover or other transaction in which unitholders might receive a premium for their partnership interests over the then prevailing market price or which unitholders might believe to be otherwise in their best interest.

The ownership limitations may restrict the ability of future investors from consummating a purchase of the Partnership’s outstanding partnership interests and thereby could have the effect of delaying, deferring or preventing a takeover or other transaction in which unitholders might receive a premium for their partnership interests over the then prevailing market price or which unitholders might believe to be otherwise in their best interest. Certain potential investors or buyers of Partnership equity may not be able to meet the ownership limitations and would therefore be unable to make an investment in the Partnership. This could have the effect of reducing the premium for which unitholders might otherwise receive in a takeover or other fundamental transaction of the Partnership.

Failure of the REIT Subsidiary to qualify, or maintain its qualification, as a REIT would have significant adverse consequences to us and the value of our common units, preferred units, and other partnership interests.

The REIT Subsidiary elected to be taxed as a REIT commencing with its taxable year ending December 31, 2017. We believe that the REIT Subsidiary has been organized in conformity with the requirements for qualification and taxation as a REIT, and that its operations have and will enable it to meet the requirements for qualification and taxation as a REIT. We have not requested and do not plan to request a ruling from the IRS, or an opinion of counsel, that the REIT Subsidiary qualifies as a REIT, and we cannot assure you that it does or will continue to so qualify. If the REIT Subsidiary fails to qualify as a REIT, the funds available for distribution to the Partnership will be substantially reduced because:

• the REIT Subsidiary would not be allowed a deduction for dividends paid to the Partnership in computing its taxable income and would be subject to U.S. federal income tax at regular corporate rates;

• the REIT Subsidiary could be subject to increased state, local and foreign taxes; and

• unless the REIT Subsidiary were entitled to relief under applicable statutory provisions, it could not elect to be taxed as a REIT for four taxable years following the year during which it was disqualified.

As substantially all of our operations are currently conducted by the REIT Subsidiary, any such corporate tax liability could be substantial and could significantly reduce cash available for, among other things, the REIT Subsidiary’s operations and distributions to the Partnership. As a result of these factors, the REIT Subsidiary’s failure to maintain its qualification as a REIT could impair our ability to expand our business, make distributions to our unitholders and raise capital, and could materially and adversely affect the value of our common units, preferred units, and other partnership interests.

Qualification as a REIT involves the application of highly technical and complex provisions of the Code for which there are only limited judicial and administrative interpretations.

The determination of various factual matters and circumstances not entirely within our control may affect our ability to maintain the REIT Subsidiary’s qualification as a REIT. In order to maintain its qualification as a REIT, the REIT Subsidiary must satisfy a number of requirements, including requirements regarding the ownership of its equity interests and requirements regarding the composition of its assets and the sources of its income. If the REIT Subsidiary is not able to maintain compliance with the various REIT qualification requirements, the REIT Subsidiary, among other things, could lose its REIT status.

The REIT Subsidiary’s disposition of its assets may jeopardize its qualification as a REIT, or create additional tax liability for the REIT Subsidiary.

To qualify as a REIT, among other things, the REIT Subsidiary must comply with requirements regarding its ownership, the composition of its assets and the sources of its income. If the REIT Subsidiary is compelled to dispose of its investments, for example to repay obligations to its lenders, including those under the Partnership’s Second Amended and Restated Credit Agreement, it may be unable to comply with these requirements, jeopardizing its qualification as a REIT. In addition, the REIT Subsidiary may be subject to a 100% penalty tax on any gain resulting from its sale of assets that are treated as dealer property or inventory. The possibility of this tax may prevent the REIT Subsidiary from selling its assets when it would like to do so.

49

In addition, to qualify as a REIT, the REIT Subsidiary generally must distribute to its owners at least 90% of its net taxable income each year (excluding any net capital gains), and it will be subject to regular corporate income tax to the extent that it distributes less than 100% of its net taxable income each year (including any net capital gains). In addition, it will be subject to a 4% nondeductible excise tax on the amount, if any, by which distributions it pays in any calendar year are less than the sum of 85% of its ordinary income, 95% of its net capital gains, and 100% of its undistributed income from prior years. To maintain its REIT status and avoid the payment of federal income and excise taxes, the REIT Subsidiary may need to borrow funds to meet the REIT distribution requirements, even if the then-prevailing market conditions are not favorable for these borrowings. These borrowing needs could result from differences in timing between the actual receipt of income and inclusion of income for federal income tax purposes. The REIT Subsidiary’s access to third-party sources of capital depends on a number of factors, including the market’s perception of its business and prospects, its current debt levels, and its current and potential future earnings. We cannot assure you that the REIT Subsidiary will have access to such capital on favorable terms at the desired times, or at all, which may cause it to curtail its investment activities and/or to dispose of assets at inopportune times, and could adversely affect its and our financial condition, results of operations, cash flow and the value of our common units, preferred units, and other partnership interests. In addition, the REIT Subsidiary may make use of “consent dividends” to meet the REIT distribution requirements, which would result in dividend income to the Partnership for federal income tax purposes, even though we would not receive a related cash distribution. Any such consent dividends could create phantom income (i.e., income without commensurate cash) for us and for our common unitholders.

Even if the REIT Subsidiary qualifies as a REIT, it may be subject to tax.

Even if the REIT Subsidiary maintains its qualification as a REIT for U.S. federal income tax purposes, the REIT Subsidiary may be subject to federal, state and local income, property and excise taxes on its income or property and, in certain cases, a 100% penalty tax, in the event it sells property as a dealer. Subsidiaries of the REIT Subsidiary that are “taxable REIT subsidiaries” will generally be required to pay federal corporate income tax on their earnings. In addition, because of our foreign operations, subsidiaries of the REIT Subsidiary are subject to foreign income and property taxes. Any taxes that the REIT Subsidiary and its subsidiaries must pay reduce the cash available for distribution to the Partnership and thus to our unitholders.

Dividends payable by REITs generally do not qualify for the reduced tax rates available for some dividends.

We anticipate that the majority of our income will consist of dividend income from the REIT Subsidiary, and this dividend income will be allocated among our unitholders. Whereas qualified dividend income allocated to unitholders that are individuals, trusts and estates generally is subject to tax at preferential rates, subject to limited exceptions, dividends payable by REITs, including the REIT Subsidiary, are not eligible for these reduced rates and are taxable at ordinary income tax rates but, U.S. stockholders that are individuals, trusts and estates generally may deduct 20% of ordinary dividends from a REIT for taxable years beginning after December 31, 2017 and before January 1, 2026. The more favorable rates applicable to regular corporate qualified dividends could cause investors who are individuals, trusts and estates to perceive an investment in us to be relatively less attractive than investments in the stocks of corporations that pay qualified dividends, which could have adverse consequences to the value of our common units, preferred units, and other partnership interests.

PART II

ITEM 5. Market for Registrant's Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities

Our common units are listed on the NASDAQ Global Market under the symbol "LMRK". Our common units represent limited partner interests in us that entitle the holders to the rights and privileges specified in our partnership agreement.

Cash Distributions

On January 26, 2021, the General Partner’s board of directors approved a quarterly distribution of $0.20 per common unit for the quarter ended December 31, 2020. The current quarter distribution equates to approximately $5.1 million per quarter, or $20.4 million per year in the aggregate, based on the number of common units outstanding as of February 18, 2021. As a result of the unprecedented economic conditions, we will focus on repaying borrowings under our revolving credit facility, preserving liquidity and capital for any potential impact to our business and positioning the Partnership to take advantage of any prospective market opportunities. We do not have a legal obligation to pay this distribution or any other distribution except to the extent we have available cash as defined in our partnership agreement. Please read “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Liquidity and Capital Resources – Revolving Credit Facility” for a discussion of the restrictions included in our revolving credit facility that may restrict our ability to pay distributions.

As of February 18, 2021, we had 107 unitholders of record of 25,488,992 common units outstanding. The number of unitholders of record does not include a substantially greater number of “street name” holders or beneficial holders of our common units, whose units are held of record by banks, brokers and other financial institutions.

Distributions of Available Cash

General

Our partnership agreement requires that, within 45 days after the end of each quarter, beginning with the quarter ending December 31, 2014, we distribute all of our available cash to unitholders of record on the applicable record date.

Definition of Available Cash

Available cash generally means, for any quarter, all cash and cash equivalents on hand at the end of that quarter:

• less, the amount of cash reserves established by our general partner to:

• provide for the proper conduct of our business (including reserves for our future capital expenditures and anticipated future debt service requirements);

• comply with applicable law, any of our or our subsidiaries’ debt instruments or other agreements; or

• provide funds for distributions to our unitholders and to our general partner for any one or more of the next four quarters (provided that our general partner may not establish cash reserves for distributions if the effect of the establishment of such reserves will prevent us from distributing the minimum quarterly distribution on all common units and any cumulative arrearages on such common units for the current quarter).

• plus, if our general partner so determines, all or any portion of the cash on hand on the date of determination of available cash for the quarter resulting from working capital borrowings made subsequent to the end of such quarter.

The purpose and effect of the last bullet point above is to allow our general partner, if it so decides, to use cash from working capital borrowings made after the end of the quarter but on or before the date of determination of available cash for that quarter to pay distributions to unitholders. Under our partnership agreement, working capital borrowings are generally borrowings that are made under a credit facility, commercial paper facility or similar financing arrangement, and in all cases are used solely for working capital purposes or to pay distributions to partners and with the intent of the borrower to repay such borrowings within twelve months with funds other than from additional working capital borrowings.

General Partner Interest and Incentive Distribution Rights

Our general partner owns a non‑economic general partner interest in us, which does not entitle it to receive cash distributions. However, our general partner may own other equity interests in us and may be entitled to receive distributions on any such interests.

51

Our general partner also holds incentive distribution rights that will entitle it to receive increasing percentages, up to a maximum of 50%, of the available cash we distribute from operating surplus (as defined below) in excess of $0.330625 per unit per quarter. The General Partner irrevocably waived its right to receive the incentive distribution and incentive allocations related to each quarterly distribution during the year ended December 31, 2019 and for the three months ended September 30, 2018 and December 31, 2018. The maximum distribution of 50% does not include any distributions that our general partner or its affiliates may receive on common units that they may own.

Percentage Allocations of Available Cash from Operating Surplus

The following table illustrates the percentage allocations of available cash from operating surplus between the unitholders and our general partner based on the specified target distribution levels. The amounts set forth under “Marginal percentage interest in distributions” are the percentage interests of our general partner and the unitholders in any available cash from operating surplus we distribute up to and including the corresponding amount in the column “Total quarterly distribution per unit target amount.” The percentage interests shown for our unitholders and our general partner for the minimum quarterly distribution are also applicable to quarterly distribution amounts that are less than the minimum quarterly distribution. The percentage interests set forth below for our general partner assume that our general partner has not transferred its incentive distribution rights and that there are no arrearages on common units.

			Marginal percentage
	Total quarterly distribution		interest in distributions
	per unit target amount		Unitholders			General Partner
Minimum Quarterly Distribution	$	0.287500		100	%		—	%
First Target Distribution	above $0.287500 up to $0.330625			100	%		—	%
Second Target Distribution	above $0.330625 up to $0.359375			85	%		15	%
Third Target Distribution	above $0.359375 up to $0.431250			75	%		25	%
Thereafter	above $0.431250			50	%		50	%

Subordinated Units and Subordination Period

General

• Our partnership agreement provides that, during the subordination period, the common units have the right to receive distributions of available cash from operating surplus each quarter in an amount equal to $0.2875 per common unit, which amount is defined in our partnership agreement as the minimum quarterly distribution, plus any arrearages in the payment of the minimum quarterly distribution on the common units from prior quarters, before any distributions of available cash from operating surplus may be made on the subordinated units. These units are deemed “subordinated” because for a period of time, referred to as the subordination period, the subordinated units are not entitled to receive any distributions until the common units have received the minimum quarterly distribution plus any arrearages in the payment of the minimum quarterly distribution on the common units from prior quarters.

The requirements described above for the subordinated units to convert were satisfied upon the payment of our quarterly cash distribution on February 14, 2018. Therefore, effective February 15, 2018, all of our subordinated units which are owned by Landmark, were converted on a one-for-one basis into common units. The conversion of subordinated units did not impact the amount of cash distributions or total number of outstanding units.

Non‑GAAP Financial Measures

EBITDA and Adjusted EBITDA

We define “EBITDA” as net income before interest, income taxes, depreciation and amortization, and we define “Adjusted EBITDA” as EBITDA before impairments, acquisition‑related expenses, unrealized and realized gains and losses on derivatives, loss on extinguishment of debt, gains and losses on sale of real property interests, unit-based compensation, straight line rental adjustments, amortization of above‑ and below‑market rents plus cash receipts applied toward the repayments of investments in receivable, the deemed capital contribution to fund our general and administrative expense reimbursement and adjustments for investments in unconsolidated joint ventures. During the third quarter of 2019, we changed our definition of EBITDA to exclude adjustments for investments in unconsolidated joint venture to adhere to the definition of EBITDA as described in item 10(e)(1)(ii)(A) of Regulation S-K. During the fourth quarter 2017, we changed our definition of Adjusted EBITDA by adding cash receipts applied toward the repayments of investments in receivables. We made this change to better reflect the quarterly amount of operating surplus as determined by our amended and restated partnership agreement. These changes did not have a material impact on our EBITDA or Adjusted EBITDA and prior period amounts have been recasted to conform to current presentation.

EBITDA and Adjusted EBITDA are non‑GAAP supplemental financial measures that management and external users of our financial statements, such as industry analysts, investors, lenders and rating agencies, may use to assess:

• our operating performance as compared to other publicly traded limited partnerships, without regard to historical cost basis or, in the case of EBITDA and Adjusted EBITDA, financing methods;

• the ability of our business to generate sufficient cash to support our decision to make distributions to our unitholders;

• our ability to incur and service debt and fund capital expenditures; and

• the viability of acquisitions and the returns on investment of various investment opportunities.

We believe that the presentation of EBITDA and Adjusted EBITDA in this Annual Report on Form 10-K provides information useful to investors in assessing our financial condition and results of operations. The GAAP measures most directly comparable to EBITDA and Adjusted EBITDA are net income and net cash provided by operating activities. EBITDA and Adjusted EBITDA should not be considered as an alternative to GAAP net income, net cash provided by operating activities or any other measure of financial performance or liquidity presented in accordance with GAAP. Each of EBITDA and Adjusted EBITDA has important limitations as analytical tools because they exclude some, but not all, items that affect net income and net cash provided by operating activities, and these measures may vary from those of other companies. You should not consider EBITDA and Adjusted EBITDA in isolation or as a substitute for analysis of our results as reported under GAAP. As a result, because EBITDA and Adjusted EBITDA may be defined differently by other companies in our industry, EBITDA and Adjusted EBITDA as presented below may not be comparable to similarly titled measures of other companies, thereby diminishing their utility.

Funds from Operations (“FFO”) and Adjusted Funds from Operations (“AFFO”)

FFO, is a non-GAAP financial measure of operating performance of an equity REIT in order to recognize that income-producing real estate historically has not depreciated on the basis determined under GAAP. We calculate FFO in accordance with the standards established by the National Association of Real Estate Investment Trust (“NAREIT”). FFO represents net income (loss) excluding real estate related depreciation and amortization expense, real estate related impairment charges, gains (or losses) on real estate transactions, adjustments for unconsolidated joint venture, and distributions to preferred unitholders and noncontrolling interests. 

55

FFO is generally considered by industry analysts to be the most appropriate measure of performance of real estate companies. FFO does not necessarily represent cash provided by operating activities in accordance with GAAP and should not be considered an alternative to net earnings as an indication of the Partnership’s performance or to cash flow as a measure of liquidity or ability to make distributions. Management considers FFO an appropriate measure of performance of an equity REIT because it primarily excludes the assumption that the value of the real estate assets diminishes predictably over time, and because industry analysts have accepted it as a performance measure. The Partnership's computation of FFO may differ from the methodology for calculating FFO used by other equity REITs, and therefore, may not be comparable to such other REITs.

AFFO is a non-GAAP financial measure of operating performance used by many companies in the REIT industry. AFFO adjusts FFO for certain non-cash items that reduce or increase net income in accordance with GAAP. AFFO should not be considered an alternative to net earnings, as an indication of the Partnership's performance or to cash flow as a measure of liquidity or ability to make distributions. Management considers AFFO a useful supplemental measure of the Partnership's performance. The Partnership's computation of AFFO may differ from the methodology for calculating AFFO used by other equity REITs, and therefore, may not be comparable to such other REITs. We calculate AFFO by starting with FFO and adjusting for general and administrative expense reimbursement, acquisition-related expenses, unrealized gain (loss) on derivatives, straight line rent adjustments, unit-based compensation, amortization of deferred loan costs and discount on secured notes, deferred income tax expense, amortization of above and below market rents, loss on early extinguishment of debt, repayments of receivables, adjustments for investment in unconsolidated joint venture, adjustments for drop-down assets and foreign currency transaction loss. The GAAP measures most directly comparable to FFO and AFFO is net income.

The following table sets forth a reconciliation of FFO and AFFO for the periods presented (in thousands):

ITEM 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Unless the context otherwise requires, references in this report to "our partnership," "we," "our," "us," or like terms refer to Landmark Infrastructure Partners LP. The following is a discussion and analysis of our financial performance, financial condition and significant trends that may affect our future performance. You should read the following in conjunction with the historical consolidated financial statements and related notes included elsewhere in this Annual Report on Form 10-K. Among other things, those historical consolidated financial statements include more detailed information regarding the basis of presentation for the following information. The following discussion and analysis contains forward‑looking statements that involve risks and uncertainties. Our actual results could differ materially from those expressed or implied in forward‑looking statements for many reasons, including the risks described in “Risk Factors” and elsewhere in this Annual Report on Form 10-K.

Overview

We are a growth‑oriented partnership formed by Landmark Divided LLC (“Landmark” or “Sponsor”) to acquire, develop, own and manage a portfolio of real property interests and infrastructure assets that are leased to companies in the wireless communication, digital infrastructure, outdoor advertising, and renewable power generation industries. In addition, the Partnership owns certain interests in receivables associated with similar assets. We generate revenue and cash flow from existing tenant leases of our real property interests and infrastructure assets to wireless carriers, cellular tower owners, outdoor advertisers, renewable power producers and colocation providers and other enterprises.

The Partnership is a master limited partnership organized in the State of Delaware and has been publicly traded since its initial public offering on November 19, 2014. On July 31, 2017, the Partnership completed changes to its organizational structure by transferring substantially all of its assets to a consolidated subsidiary, Landmark Infrastructure Inc., a Delaware corporation, which elected to be taxed as a REIT commencing with its taxable year ending December 31, 2017. We intend to continue to own and operate substantially all of our assets through the REIT Subsidiary. These changes are designed to simplify tax reporting for unitholders and broaden the Partnership’s investor base by substantially eliminating unrelated business taxable income allocated by the Partnership to tax-exempt investors, including individuals investing through tax-deferred accounts such as an individual retirement account, and we do not intend to generate state source income.

COVID-19

We are closely monitoring the impact of COVID-19 pandemic on all aspects of our business and in all of the jurisdictions in which we operate, including how it will impact our tenants and business partners. While we did not incur significant disruptions during the year ended December 31, 2020 from the COVID-19 pandemic, we are unable to predict the future impact that the COVID-19 pandemic will have on our financial condition, results of operations and cash flows due to numerous uncertainties. These uncertainties include the scope, severity and duration of the pandemic, the actions taken to contain the pandemic or mitigate its impact and the direct and indirect economic effects of the pandemic and containment measures, among others. The global impact of the outbreak has been rapidly evolving and, as cases of COVID-19 have continued to be identified in additional countries, many countries, including the United States, have reacted by instituting quarantines, mandating business and school closures and restricting travel. As a result, the COVID-19 pandemic is negatively impacting the global economy. Further, the impacts of a potential worsening of global economic conditions and the continued disruptions to, and volatility in, the credit and financial markets, consumer spending as well as other unanticipated consequences remain unknown.

In addition, we cannot predict the impact that COVID-19 will have on our tenants and other business partners; however, any material effect on these parties could adversely impact us. The current economic conditions, including the “stay-at-home” orders and similar mandates, have had and will likely continue to have a negative effect on the outdoor advertising industry. The Partnership has received and is currently reviewing a myriad of short-term rent relief requests from tenants within the outdoor advertising industry, most often in the form of rent deferral requests or amending to percentage rent. Not all tenant requests will ultimately result in modification agreements, nor is the Partnership forgoing its contractual rights under its lease agreements. The twelve months ended December 31, 2020 results may not be indicative of future results. During the year ended December 31, 2020, the Partnership generated $15.2 million in rental revenue from outdoor advertising tenants, $0.7 million of which was generated from percentage rent provisions.

How We Generate Rental Revenue

We primarily generate rental revenue and cash flow from existing leases of our tenant sites to wireless carriers, cellular tower owners, outdoor advertisers, renewable power producers and colocation providers and other enterprises. The amount of rental revenue generated by the assets in our portfolio depends principally on occupancy levels and the tenant lease rates and terms at our tenant sites.

57

We believe the terms of our tenant leases provide us with stable, predictable and growing cash flow. Substantially all of our tenant lease arrangements are triple net or effectively triple net, meaning that our tenants or the underlying property owners are generally contractually responsible for property‑level operating expenses, including maintenance capital expenditures, property taxes and insurance. For certain infrastructure assets, we incur ground rent obligations, maintenance expenditures, property taxes and insurance, some of which may be reimbursed by our tenants. In addition, as of December 31, 2020, 83% of our tenant leases (94% of rental revenue for the three months ended December 31, 2020) have contractual fixed‑rate escalators or consumer price index (“CPI”) ‑based rent escalators, and some of our tenant leases contain revenue‑sharing provisions in addition to the base monthly or annual rental payments. Occupancy rates under our tenant leases have historically been very high. We also believe we are well positioned to negotiate higher rents in advance of lease expirations as tenants request lease amendments to accommodate equipment upgrades or add tenants to increase colocation.

Future economic or regional downturns affecting our submarkets that impair our ability to renew or re‑lease our real property interests and other adverse developments that affect the ability of our tenants to fulfill their lease obligations, such as tenant bankruptcies, could adversely affect our ability to maintain or increase rental rates at our sites. Adverse developments or trends in one or more of these factors could adversely affect our rental revenue and tenant recoveries in future periods.

Significant consolidation among our tenants in the wireless communication industry (or our tenants’ sub‑lessees) may result in the decommissioning of certain existing communications sites, because certain portions of these tenants’ (or their sub‑lessees’) networks may be redundant. The loss of any one of our large customers as a result of joint ventures, mergers, acquisitions or other cooperative agreements may result in a material decrease in our revenue. On April 1, 2020, T-Mobile and Sprint completed their merger. The Partnership does not expect the merger to have a material impact on rental revenue. For the year ended December 31, 2020, T-Mobile represented approximately 14% of rental revenue.

How We Evaluate Our Operations

Our management uses a variety of financial and operating metrics to analyze our performance. These metrics are significant factors in assessing our operating results and profitability and include: (1) occupancy and rental revenue; (2) operating and maintenance expenses; (3) FFO and AFFO; and (4) EBITDA and Adjusted EBITDA.

Occupancy and Rental Revenue

The amount of revenue we generate primarily depends on our occupancy rate. As of December 31, 2020, we had a 94% occupancy rate with 1,874 of our 1,986 available tenant sites leased. We believe the infrastructure assets at our tenant sites are essential to the ongoing operations and profitability of our tenants and will be a critical component for the rollout of future technologies such as 5G, Internet of Things (IoT) and autonomous vehicles. Combined with the challenges and costs of relocating the infrastructure, we believe that we will continue to enjoy high tenant retention and occupancy rates.

There has been consolidation in the wireless communication industry historically that has led to certain lease terminations. On April 1, 2020, T-Mobile and Sprint completed their merger. The Partnership does not expect the merger to have a material impact on rental revenue. For the year ended December 31, 2020, T-Mobile represented approximately 14% of rental revenue. Additional consolidation among our tenants in the wireless communication industry (or our tenants’ sub‑lessees) may result in lease terminations for certain existing communication sites. Any additional termination of leases in our portfolio would result in lower rental revenue, may lead to impairment of our real property interests, or other adverse effects to our business.

Operating and Maintenance Expenses

Substantially all of our tenant sites are subject to triple net or effectively triple net lease arrangements, which require the tenant or the underlying property owner to pay all utilities, property taxes, insurance and repair and maintenance costs. Our overall financial results could be impacted to the extent the owners of the fee interest in the real property or our tenants do not satisfy their obligations or to the extent a jurisdiction applies real property tax to our easements.

FFO and AFFO

FFO is a non-GAAP financial measure of operating performance of an equity REIT in order to recognize that income-producing real estate historically has not depreciated on the basis determined under GAAP. We calculate FFO in accordance with the standards established by the National Association of Real Estate Investment Trust (“NAREIT”). FFO represents net income (loss) excluding real estate related depreciation and amortization expense, real estate related impairment charges, gains (or losses) on real estate transactions, adjustments for unconsolidated joint venture, and distributions to preferred unitholders and noncontrolling interests.  

58

FFO is generally considered by industry analysts to be the most appropriate measure of performance of real estate companies. FFO does not necessarily represent cash provided by operating activities in accordance with GAAP and should not be considered an alternative to net earnings as an indication of the Partnership’s performance or to cash flow as a measure of liquidity or ability to make distributions. Management considers FFO an appropriate measure of performance of an equity REIT because it primarily excludes the assumption that the value of the real estate assets diminishes predictably over time, and because industry analysts have accepted it as a performance measure. The Partnership's computation of FFO may differ from the methodology for calculating FFO used by other equity REITs, and therefore, may not be comparable to such other REITs.

AFFO is a non-GAAP financial measure of operating performance used by many companies in the REIT industry. AFFO adjusts FFO for certain non-cash items that reduce or increase net income in accordance with GAAP. AFFO should not be considered an alternative to net earnings, as an indication of the Partnership's performance or to cash flow as a measure of liquidity or ability to make distributions. Management considers AFFO a useful supplemental measure of the Partnership's performance. The Partnership's computation of AFFO may differ from the methodology for calculating AFFO used by other equity REITs, and therefore, may not be comparable to such other REITs. We calculate AFFO by starting with FFO and adjusting for general and administrative expense reimbursement, acquisition-related expenses, unrealized gain (loss) on derivatives, straight line rent adjustments, unit-based compensation, amortization of deferred loan costs and discount on secured notes, deferred income tax expense, amortization of above and below market rents, loss on extinguishment of debt, repayments of receivables, adjustments for investment in unconsolidated joint venture, adjustments for drop-down assets and foreign currency transaction gain (loss). The GAAP measures most directly comparable to FFO and AFFO is net income.

EBITDA and Adjusted EBITDA

We define EBITDA as net income before interest, income taxes, depreciation and amortization, and we define Adjusted EBITDA as EBITDA before impairments, acquisition‑related expenses, unrealized and realized gains and losses on derivatives, loss on extinguishment of debt, gains and losses on sale of real property interests, unit-based compensation, straight line rental adjustments, amortization of above‑ and below‑market rents plus cash receipts applied toward the repayments of investments in receivable, the deemed capital contribution to fund our general and administrative expense reimbursement and adjustments for investments in unconsolidated joint ventures. During the third quarter of 2019, we changed our definition of EBITDA to exclude adjustments for investments in unconsolidated joint venture to adhere to the definition of EBITDA as described in item 10(e)(1)(ii)(A) of Regulation S-K. During the fourth quarter 2017, we changed our definition of Adjusted EBITDA by adding cash receipts applied toward the repayments of investments in receivables. We made this change to better reflect the quarterly amount of operating surplus as determined by our amended and restated partnership agreement. These changes did not have a material impact on our EBITDA or Adjusted EBITDA and prior period amounts have been recasted to conform to current presentation.

EBITDA and Adjusted EBITDA are non‑GAAP supplemental financial measures that management and external users of our financial statements, such as industry analysts, investors, lenders and rating agencies, may use to assess:

• our operating performance as compared to other publicly traded limited partnerships, without regard to historical cost basis or, in the case of Adjusted EBITDA, financing methods;

• the ability of our business to generate sufficient cash to support our decision to make distributions to our unitholders;

• our ability to incur and service debt and fund capital expenditures; and

• the viability of acquisitions and the returns on investment of various investment opportunities.

We believe that the presentation of EBITDA and Adjusted EBITDA in this Annual Report on Form 10-K provides information useful to investors in assessing our financial condition and results of operations. The GAAP measures most directly comparable to EBITDA and Adjusted EBITDA are net income and net cash provided by operating activities. EBITDA and Adjusted EBITDA should not be considered as an alternative to GAAP net income, net cash provided by operating activities or any other measure of financial performance or liquidity presented in accordance with GAAP. Each of EBITDA and Adjusted EBITDA has important limitations as analytical tools because they exclude some, but not all, items that affect net income and net cash provided by operating activities, and these measures may vary from those of other companies. You should not consider EBITDA and Adjusted EBITDA in isolation or as a substitute for analysis of our results as reported under GAAP. As a result, because EBITDA and Adjusted EBITDA may be defined differently by other companies in our industry, EBITDA and Adjusted EBITDA as presented below may not be comparable to similarly titled measures of other companies, thereby diminishing their utility.

For a further discussion of the non‑GAAP financial measures of FFO, AFFO, EBITDA and Adjusted EBITDA flow, and a reconciliation of FFO, AFFO, EBITDA and Adjusted EBITDA to the most comparable financial measures calculated and presented in accordance with GAAP, please read “Selected Historical Financial Data – Non‑GAAP Financial Measures.”

Factors Affecting the Comparability of Our Financial Results

Our future results of operations may not be comparable to our historical results of operations for the reasons described below:

COVID-19

We are not aware of any material trends or uncertainties, other than national economic conditions affecting real estate and development generally and those risks listed in Part I, Item 1A of this Annual Report on Form 10-K, that may reasonably be expected to have a material impact, favorable or unfavorable, on revenues or income from the acquisition, management and operation of our properties. However, due to the recent outbreak of COVID-19, the Partnership’s tenants and their operations may be impacted, including their ability to pay rent. The impact of COVID-19 on our future results could be significant and will largely depend on future developments, which are highly uncertain and cannot be predicted, including new information that may emerge concerning the severity of COVID-19, the success of actions taken to contain or treat COVID-19 and reactions by consumers, companies, governmental entities and capital markets.

Investment in Unconsolidated Joint Venture

On September 24, 2018, the Partnership completed the formation of an unconsolidated joint venture (the “JV”). The Partnership contributed 545 tenant site assets to the unconsolidated JV that secured the Partnership’s $125.4 million Series 2018-1 secured notes (the “2018 Securitization”), in exchange for a 50.01% membership interest in the unconsolidated JV and $65.5 million in cash (the “Transaction”). The Partnership used $59.7 million of the net proceeds to repay a portion of the borrowings under the revolving credit facility. The Partnership deconsolidated the 545 tenant sites and real property interests and recognized a gain on contribution of real property interests of $100 million. The Partnership does not control the unconsolidated JV and therefore, accounts for its investment in the unconsolidated JV using the equity method of accounting prospectively upon formation of the unconsolidated JV.

Acquisitions and Developments

We have in the past and intend to continue to pursue acquisitions of real property interests and developments of infrastructure. Our significant historical acquisition activity impacts the period to period comparability of our results of operations. During the year ended December 31, 2018, the Partnership completed one drop-down acquisition from our Sponsor and affiliates (collectively the “Drop-down Acquisitions” or “Drop-down Assets”). The Drop-down Assets acquired by the Partnership included an aggregate of 127 tenant sites for the year ended December 31, 2018 in exchange for total consideration of $59.9 million. The Drop-down Acquisitions are a transfer of net assets between entities under common control as the acquisitions do not meet the definition of a business in accordance with ASU No. 2017-01. The transfer of net assets is accounted for prospectively in the period in which the transfer occurs at the net carrying value. Any differences between the cash consideration and the net carrying value of the transfer of net assets have been allocated to the General Partner.

Additionally, during the years ended December 31, 2020, 2019 and 2018, the Partnership acquired 15 tenant sites, 146 tenant sites and 104 tenant sites from third parties for a total consideration of $144.2 million, $52.0 million and $75.8 million, respectively. See Note 3, Acquisitions, to the Consolidated Financial Statements for additional information. In 2020, we focused on the acquisition of multiple data center properties with long-term triple net leases totaling $142.8 million.

Sales

The Partnership’s sales of real property interests impacts the period to period comparability of our results of operations. During the year ended December 31, 2020, the Partnership completed the sale of its interest in the consolidated joint venture that holds its European outdoor advertising portfolio and recognized a gain on sale of real property interest of $15.5 million. The operating results of the European outdoor advertising portfolio and the related gain on sale are presented as discontinued operations on the consolidated statements of operations. Accordingly, for all prior periods presented, the related assets and liabilities are presented as assets and liabilities held for sale on the consolidated balance sheets. The Partnership used proceeds from the sale of the European outdoor advertising portfolio and available cash to repay borrowings totaling $115 million on its revolving credit facility, including the £40.5 million of British pound sterling (“GBP”) denominated borrowings, and terminate USD interest rate swaps with a notional value of $145 million and a GBP denominated interest rate swap agreement with a notional value of £38 million for approximately $7.6 million. During the year ended December 31, 2019, the Partnership completed sales of its real property interests and investments in receivables for total consideration of $46.4 million and recognized a gain on sale of $18.0 million.  

Secured Notes

On January 15, 2020, certain subsidiaries of the Partnership entered into a master note purchase and participation agreement (“MNPPA”) pursuant to which such subsidiaries issued and sold an initial $170 million aggregate principal amount of 3.90% series A senior secured notes in a private placement (the “2019 Secured Notes”). The 2019 Secured Notes mature on January 14, 2027 and include an interest-only initial term of three years. The net proceeds were used to repay in full the 2016 Secured Notes by $108 million and the revolving credit facility by $59 million. In connection with the issuance of the senior secured notes, the Partnership obtained a standby letter of credit arrangement totaling $3.4 million.

60

On June 6, 2018, the Partnership completed the 2018 Securitization involving a segregated pool of wireless communication sites and related property interests owned by certain special purpose subsidiaries of the Partnership, through the issuance of the 2018-1 Secured Tenant Site Contract Revenue Notes, Class C, Class D and Class F (the “2018 Secured Notes”), in an aggregate principal amount of $125.4 million. The Class C, Class D and Class F 2018 Secured Notes bear interest at a fixed note rate per annum of 3.97%, 4.70% and 5.92%, respectively. On September 24, 2018, the Partnership completed the formation of an unconsolidated joint venture by contributing certain special purpose subsidiaries to the unconsolidated joint venture, including the 2018 Secured Notes. See Note 8, Investment in Unconsolidated Joint Venture and Consolidated Financial Statements for additional information. 

On April 24, 2018, a special purpose subsidiary of the Partnership entered into a note purchase and private shelf agreement (the “Note Purchase Agreement”) pursuant to which such subsidiary agreed to sell approximately $43.7 million aggregate principal amount of its 4.38% senior secured notes in a private placement (the “4.38% Senior Secured Notes”). The 4.38% Senior Secured Notes are fully amortizing through June 30, 2036. The 4.38% Senior Secured Notes are secured by a segregated pool of renewable power generation sites and related property interests owned directly or indirectly by such subsidiary.

The secured notes described above are collectively referred to as the “Secured Notes.” See Note 9, Debt to the Consolidated Financial Statements for additional information.

Revolving Credit Facility

On November 15, 2018, the Partnership completed its Third Amended and Restated Credit Facility and obtained commitments from a syndicate of banks with initial borrowing commitments of $450.0 million for five-years. Additionally, borrowings up to $75.0 million may be denominated in GBP, Euro, Australian dollar and Canadian dollar. Loans under the revolving credit facility bear interest at a rate equal to the applicable LIBOR related to the currency for which borrowings are denominated, plus a spread ranging from 1.75% to 2.25% (determined based on leverage levels). As of December 31, 2020, the applicable spread was 2.25%. Additionally, under the revolving credit facility we will be subject to an annual commitment fee (determined based on leverage levels) associated with the available undrawn capacity subject to certain restrictions. As of December 31, 2020, the applicable annual commitment rate used was 0.20%.

Series C Preferred Units

On April 2, 2018, the Partnership completed a public offering of 2,000,000 Series C Floating-to-Fixed Rate Cumulative Perpetual Redeemable Convertible Preferred Units (“Series C Preferred Units”), representing limited partner interest in the Partnership, at a price of $25.00 per unit. We received net proceeds of approximately $47.5 million after deducting underwriters’ discounts and offering expenses paid by us of $2.5 million. We used substantially all net proceeds to repay a portion of the borrowings under our revolving credit facility.

Holders of Series C Preferred Units, at their option, may, at any time and from time to time, convert some or all of their Series C Preferred Units based on an initial conversion rate of 1.3017 common units per Series C Preferred Unit. In the event of a fundamental change, holder of the Series C Preferred Units, at their option, may convert some or all of their Series C Preferred Units into the greater of (i) a number of common units plus a make-whole premium and (ii) a number of common units equal to the lessor of (a) the liquidation preference divided by the market value of our common units on the effective date of such fundamental change and (b) 11.13 (subject to adjustments). On May 15, 2025, May 15, 2028, and each subsequent five-year anniversary date thereafter (each such date, a “designated redemption date”), each holder of Series C Preferred Units shall have the right (a “redemption right”) to require the Partnership to redeem any or all of the Series C Preferred Units held by such holder outstanding on such designated redemption date at a redemption price equal to the liquidation preference of $25.00, plus all accrued and unpaid distributions to, but not including, in each case out of funds legally available for such payment and to the extent not prohibited by law, the designated redemption date (the “put redemption price”). At our option we may pay the redemption in our common units or cash, subject to certain limitations.

At any time on or after May 20, 2025, the Partnership shall have the option to redeem the Series C Preferred Units, in whole or in part, at a redemption price of $25.00 per Series C Preferred Unit plus an amount equal to all accumulated and unpaid distributions thereon to the date of redemption, whether or not declared. See Note 12, Equity to the Consolidated Financial Statements for additional information.

Derivative Financial Instruments

Historically we have hedged a portion of the variable interest rates under our secured debt facilities through interest rate swap agreements. We have not applied hedge accounting to these derivative financial instruments which has resulted in the change in the fair value of the interest rate swap agreements to be reflected in income as either a realized or unrealized gain (loss) on derivatives, except for foreign currency changes on interest rate swaps denominated in a foreign currency. In connection with the sale of the European outdoor advertising portfolio, the Partnership used proceeds from the sale to terminate existing USD interest rate swaps with a notional value of $145 million and a GBP denominated interest rate swap agreement with a notional value of £38 million for approximately $7.6 million. On September 29, 2020, the Partnership entered into an interest rate swap agreement with a notional amount of $60 million with a fixed rate at 0.18% per annum and a maturity date of November 15, 2023. On December 30, 2020, the Partnership entered into an interest rate swap agreement with a notional amount of $40 million with a fixed rate at 0.21% per annum and a maturity date of November 15, 2023.

61

General and Administrative Expenses

Under the Partnership’s Fourth Amended and Restated Agreement of Limited Partnership of Landmark Infrastructure Partners LP dated April 2, 2018 (the “Amended Partnership Agreement”), we are required to reimburse our general partner and its affiliates for all costs and expenses that they incur on our behalf for managing and controlling our business and operations. Except to the extent specified under our amended Omnibus Agreement with Landmark (the “Omnibus Agreement”), which was amended on January 30, 2019, our general partner determines the amount of these expenses and such determinations must be made in good faith under the terms of the Partnership Agreement. Under the Omnibus Agreement, we agreed to reimburse Landmark for expenses related to certain general and administrative services that Landmark will provide to us in support of our business, subject to a quarterly cap equal to 3% of our revenue during the current calendar quarter. This cap on expenses will last until the earlier to occur of: (i) the date on which our revenue for the immediately preceding four consecutive fiscal quarters exceeded $120 million and (ii) November 19, 2021. The full amount of our general and administrative expenses incurred will be reflected on our income statements, and to the extent such general and administrative expenses exceed the cap amount, the amount of such excess will be reflected in our financial statements as a capital contribution from Landmark rather than as a reduction of our general and administrative expenses, except for expenses that would otherwise be allocated to us, which are not included in the amount of general and administrative expenses.

Factors That May Influence Future Results of Operations

COVID-19

We are not aware of any material trends or uncertainties, other than national economic conditions affecting real estate and development generally and those risks listed in Part I, Item 1A of this Annual Report on Form 10-K for the year ended December 31, 2020, that may reasonably be expected to have a material impact, favorable or unfavorable, on revenues or income from the acquisition, management and operation of our properties. However, due to the recent outbreak of COVID-19, the Partnership’s tenants and their operations may be impacted, including their ability to pay rent. The impact of COVID-19 on our future results could be significant and will largely depend on future developments, which are highly uncertain and cannot be predicted, including new information that may emerge concerning the severity of COVID-19, the success of actions taken to contain or treat COVID-19 and reactions by consumers, companies, governmental entities and capital markets.

Acquisitions and Developments

We intend to pursue acquisitions of real property interests from third parties and developments of infrastructure, utilizing the expertise of our management and other Landmark employees to identify and assess potential acquisitions, for which we may pay Landmark mutually agreed reasonable fees. When acquiring real property interests, we will target infrastructure locations that are essential to the ongoing operations and profitability of our tenants, which we expect will result in continued high tenant occupancy and enhance our cash flow stability. For our digital infrastructure industry, we focus on acquiring mission-critical, high-quality, network-neutral, single and multi-tenant data centers, primarily supporting colocation/cloud, wholesale colocation and enterprise tenants, in strategic markets. We expect the data center assets to have high-quality anchor tenants in place for whom the data center is critically important for its continued operations as well as leases that are structured on a long-term, net basis and contain contractual rent escalators. Additionally, we will focus on infrastructure locations with characteristics that are difficult to replicate in their respective markets, and those with tenant assets that cannot be easily moved to nearby alternative sites or replaced by new construction. Although our initial portfolio is focused on wireless communication, outdoor advertising and renewable power generation assets in the United States, we intend to grow our initial portfolio of real property interests into other fragmented infrastructure asset classes and expect to continue to pursue acquisitions internationally. The impact of COVID-19 may restrict access to construction materials and delay development projects.

During 2017, the Partnership started developing an ecosystem of technologies that provides smart enabled infrastructure including stealth towers and digital outdoor advertising kiosks across North America. Stealth towers are self-contained, neutral-host towers designed for wireless carrier and other wireless operator collocation. The stealth towers are designed for macro, mini macro and small cell deployments and will support Internet of Things (IoT), carrier densification needs, private LTE networks and other wireless solutions.

During the fourth quarter of fiscal year 2018, the Partnership entered into an agreement with DART to develop a smart media and communications platform which will include the deployment of content-rich kiosks and the Partnership’s smart enabled infrastructure ecosystem solution on strategic high-traffic DART locations.

During the years ended December 31, 2020, the Partnership deployed two stealth towers, 112 DART kiosks and placed in service other assets for a total of $16.2 million. During the years ended December 31, 2019 and 2018, the Partnership deployed nine and four infrastructure sites totaling $1.0 million and $1.5 million, respectively. As we deploy these infrastructure assets, we may incur additional operating expenses associated with ground lease payments and other operating expenses to maintain our infrastructure assets. Additionally, the Partnership may pursue further development opportunities in the future. The impact of COVID-19 has at times limited access to construction materials and delayed development projects and may continue to impact the pace of developments.

62

Investment in Unconsolidated Joint Venture

On September 24, 2018, the Partnership completed the formation of the unconsolidated JV. The Partnership contributed 545 tenant site assets to the unconsolidated JV that secured the Partnership’s 2018 Securitization in exchange for a 50.01% membership interest in the unconsolidated JV and $65.5 million in cash. The Partnership does not control the unconsolidated JV and therefore, accounts for its investment in the unconsolidated JV using the equity method of accounting prospectively upon formation of the unconsolidated JV.

Sales

During the year ended December 31, 2020, the Partnership completed the sale of its interest in the consolidated joint venture that holds its European outdoor advertising portfolio and recognized a gain on sale of real property interest of $15.5 million in discontinued operations. The Partnership used proceeds from the sale of the European outdoor advertising portfolio and available cash to repay borrowings totaling $115 million on its revolving credit facility, including the £40.5 million of GBP denominated borrowings, and terminate USD interest rate swaps with a notional value of $145 million and a GBP denominated interest rate swap agreement with a notional value of £38 million for approximately $7.6 million.

Mergers

Significant consolidation among our tenants in the wireless communication industry (or our tenants’ sub‑lessees) may result in the decommissioning of certain existing communications sites, because certain portions of these tenants’ (or their sub‑lessees’) networks may be redundant. The loss of any one of our large customers as a result of joint ventures, mergers, acquisitions or other cooperative agreements may result in a material decrease in our revenue. On April 1, 2020, T-Mobile and Sprint completed their merger. For the year ended December 31, 2020, T-Mobile represented approximately 14% of rental revenue.

Revolving Credit Facility

On November 15, 2018, the Partnership completed its Third Amended and Restated Credit Facility and obtained commitments from a syndicate of banks with initial borrowing commitments of $450.0 million for five-years. Additionally, borrowings up to $75.0 million may be denominated in GBP, Euro, Australian dollar and Canadian dollar. As of November 1, 2019, the outstanding indebtedness under the revolving credit facility denominated in GBP was £40.5 million. Loans under the revolving credit facility bear interest at a rate equal to LIBOR, plus a spread ranging from 1.75% to 2.25% (determined based on leverage levels). As of December 31, 2020, the applicable spread was 2.25%. Additionally, under the revolving credit facility we will be subject to an annual commitment fee (determined based on leverage levels) associated with the available undrawn capacity subject to certain restrictions. As of December 31, 2020, the applicable annual commitment rate used was 0.20%.

Secured Notes

On January 15, 2020, certain subsidiaries of the Partnership entered into a MNPPA pursuant to which such subsidiaries issued and sold an initial $170 million aggregate principal amount of 3.90% series A senior secured notes in a private placement. The senior secured notes mature on January 14, 2027 and include an interest-only initial term of three years. The net proceeds were used to repay in full the 2016 Secured Notes by $108 million and the revolving credit facility by $59 million. In connection with the issuance of the senior secured notes, the Partnership obtained a standby letter of credit arrangement totaling $3.4 million.

Changing Interest Rates and Foreign Currency Exchange Rates

Interest rates have been at or near historic lows in recent years. If interest rates rise, this may impact the availability and terms of debt financing, our interest expense associated with existing and future debt or our ability to make accretive acquisitions. Additionally, fluctuations in foreign currencies in which the Partnership operates may impact the availability and terms of debt financing, our interest expense associated with existing and future debt or our ability to make accretive acquisitions.

LIBOR Phase Out

In July 2017, the FCA, which regulates LIBOR, announced it intends to stop compelling banks to submit rates for the calculation of LIBOR after 2021. As a result, the Federal Reserve Board and the Federal Reserve Bank of New York organized the ARRC which identified the SOFR as its preferred alternative to USD-LIBOR in derivatives and other financial contracts. The Partnership is not able to predict when LIBOR will cease to be available or when there will be sufficient liquidity in the SOFR markets. Any changes adopted by FCA or other governing bodies in the method used for determining LIBOR may result in a sudden or prolonged increase or decrease in reported LIBOR. If that were to occur, our interest payments could change. In addition, uncertainty about the extent and manner of future changes may result in interest rates and/or payments that are higher or lower than if LIBOR were to remain available in its current form.

63

The Partnership has agreements that are indexed to LIBOR and is monitoring and evaluating the related risks, which include interest on loans and valuation of derivative instruments. These risks arise in connection with transitioning contracts to a new alternative rate, including any resulting value transfer that may occur. The value of loans or derivative instruments tied to LIBOR could also be impacted if LIBOR is limited or discontinued. For some instruments, the method of transitioning to an alternative rate may be challenging, as they may require negotiation with the respective counterparty.

If a contract is not transitioned to an alternative rate and LIBOR is discontinued, the impact on our contracts is likely to vary by contract. If LIBOR is discontinued or if the methods of calculating LIBOR change from their current form, interest rates on our current or future indebtedness may be adversely affected.

While we expect LIBOR to be available in substantially its current form until the end of 2021, it is possible that LIBOR will become unavailable prior to that point. This could result, for example, if sufficient banks decline to make submissions to the LIBOR administrator. In that case, the risks associated with the transition to an alternative reference rate will be accelerated and magnified. Our revolving credit facility contains fallback language generally consistent with the ARRC’s amendment approach, which provides a streamlined amendment approach for negotiating a benchmark replacement and introduces clarity with respect to the fallback trigger events and an adjustment to be applied to the successor rate. We continue to monitor developments by the ARRC and the potential impact of LIBOR changes on our business.

Critical Accounting Policies

The following discussion of critical accounting policies uses “we”, “our” and the “Partnership” interchangeably. Our discussion and analysis of the historical financial condition and results of operations of the Partnership are based upon our consolidated financial statements, which have been prepared in accordance with GAAP. The preparation of these financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amount of revenue and expenses in the reporting period. Actual amounts may differ from these estimates and assumptions. We have provided a summary of significant accounting policies in Note 2 to the consolidated financial statements of the Partnership, included elsewhere in Part IV, Item 15(a)(1). We have summarized below those accounting policies that require material subjective or complex judgments and that have the most significant impact on financial condition and results of operations. Management evaluates these estimates on an ongoing basis, based upon information currently available and on various assumptions that it believes are reasonable as of the date hereof. In addition, other companies in similar businesses may use different estimation policies and methodologies, which may impact the comparability of our results of operations and financial condition to those of other companies.

A critical accounting policy is one that is both important to the portrayal of an entity’s financial condition and results of operations and requires judgment on the part of management. Generally, the judgment requires management to make estimates and assumptions about the effect of matters that are inherently uncertain. Estimates are prepared using management’s best judgment, after considering past and current economic conditions and expectations for the future. Changes in estimates could affect our financial position and specific items in our results of operations that are used by the users of our financial statements in their evaluation of our performance. Of the accounting policies discussed in the notes to the consolidated financial statements of the Partnership, included in Part IV, Item 15(a)(1), the accounting policies presented below have been identified by us as critical accounting policies.

Purchase Accounting for Acquisitions

The Partnership applies the asset acquisition method to all acquired investments of real property interests for transactions that meet the definition of an asset acquisition. The purchase consideration of the real property interests is allocated to the acquired tangible asset, such as land and building, and the identified intangible assets and liabilities, consisting of the value of perpetual and limited life easements, above‑market and below‑market leases and in‑place leases, based in each case on their fair values. The fair value of the assets acquired and liabilities assumed is typically determined by using the discounted cash flow valuation method. In certain instances, such as data center acquisitions, the sales comparison approach is used to determine the fair value of the land assets, the cost approach to determine the fair value of the building and site improvements, and the income approach to determine the fair value of the real property interest and liability assumed. When determining the fair value of intangible assets acquired, the Partnership estimates the applicable discount rate and the timing and amount of future cash flows. Transaction costs related to asset acquisitions are capitalized.

Factors considered in estimating the fair value of tangible and intangible assets acquired include information obtained about each asset as a result of Landmark’s pre‑acquisition due diligence and its marketing and leasing activities. In order to calculate the estimated in‑place lease value, we employed the income approach in accordance with ASC 805 by multiplying the anticipated market absorption period by the market rent at the time of acquisition for each in‑place lease agreement. Based on our experience in the industry, we have determined a range of lease execution timelines to be between one and twelve months. For the in‑place lease valuation, we consider a lease‑up period of four to eight months to be representative of the market.

We estimated the fair value of real property interests using the income approach. The discount rates used ranged from 6% to 20% with a weighted average discount rate of 8.5%. In certain instances, such as data center acquisitions, the sales comparison approach is used to determine the fair value of the land assets, the cost approach to determine the fair value of the building and site improvements, and the income approach to

64

determine the fair value of the real property interest and liability assumed. The value of tenant relationships has not been separated from in‑place tenant lease value for the real estate acquired as such value and its consequence to amortization expense is materially consistent with the in‑place lease value for these particular acquisitions. Should future acquisitions of real property interests result in allocating material amounts to the value of tenant relationships, an amount would be separately allocated and amortized over the estimated life of the relationship. The value of in‑place leases and customer relationship is amortized to expense over the estimated period the tenant is expected to be leasing the site under the existing terms which typically range from 2 to 20 years. If a tenant lease were to be terminated prior to its stated expiration, all unamortized amounts relating to that lease would be impaired.

The discount rate associated with each asset varies based on the location of an asset (including demographics and zoning restrictions), and other asset specific characteristics. Market rent for each asset is determined based on location of each asset, asset type, zoning restrictions, ground space necessary for the tenant’s equipment, remaining site capacity, visibility (specifically for billboards), and nearby sites.

In allocating the purchase consideration of the identified intangible assets and liabilities of an acquired asset, above‑market, below‑market and in‑place lease values are calculated based on the present value (using an interest rate that reflects the risks associated with the leases acquired) of the difference between (i) the contractual amounts to be paid pursuant to the in‑place leases and (ii) management’s estimate of fair market lease rates for the corresponding in‑place leases measured over the estimated period the tenant is expected to be leasing the site under the above or below‑market terms. The capitalized above‑market and below‑market lease values are amortized as a decrease or increase, respectively, to rental income over the estimated period the tenant is expected to be leasing the site. Wireless communication and outdoor advertising tenant leases obtained by us through acquisition of real property interests are generally cancellable, upon 30 to 180 days’ notice by the tenants, with no significant penalty. Digital infrastructure and renewable power generation tenant leases are generally non-cancellable. With respect to below‑market leases, consideration is given to any below‑market renewal periods. However, for wireless communication assets, we estimated the above‑ or below‑market lease value over an analysis period of the earlier of the lease expiration or 10 years based on estimated useful life of the underlying equipment and assets. For outdoor advertising assets, we estimated the above‑ or below‑market lease value over an analysis period of the earlier of the lease expiration or 20 years, based on a longer estimated useful life of 20 years for outdoor advertising assets.

Impairment of Long‑Lived Assets and Development Projects

We assess the carrying values of our long‑lived assets whenever events or changes in circumstances indicate that the carrying amounts of these assets may not be fully recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount to the future net cash flow, undiscounted and without interest, expected to be generated by the asset.

In evaluating our assets for recoverability, we consider current market conditions, as well as our intent with respect to holding or disposing of the asset. Our intent with regard to the underlying assets might change as market conditions change, as well as other factors. Fair value is determined through various valuation techniques, including the income approach using a market discount rate, terminal capitalization rate and rental rate assumptions, or on the sales comparison approach to similar assets. If our analysis indicates that the carrying value of the asset is not recoverable, we recognize an impairment charge for the amount by which the carrying value exceeds the current estimated fair value of the asset. Assets to be disposed of are reported at the lower of the carrying amount or fair value, less costs to sell.

Assumptions and estimates used in the recoverability analyses for future cash flow, discount rates and capitalization rates are complex and subjective. Changes in economic and operating conditions or our intent with regard to our assets that occurs subsequent to our impairment analyses could impact these assumptions and result in future impairments of our assets.

Development projects and other similar contracts are also assessed to determine whether it continues to meet our investment return standards. Assessments are made separately for each project on a quarterly basis and are affected by the following factors relative to the market in which the asset is located, among others: estimated development and construction costs and projected profitability. When a decision is made to cease construction on certain projects due to market conditions and/or fluctuations in our development strategy, we write off the related capitalized costs, including pre-construction costs. Based on the results of our assessments, there were no construction in progress impairment charges during the year ended December 31, 2020. During the year ended December 31, 2019, we recognized impairment charges related to certain construction in progress of $1.6 million and included in impairment in our consolidated statements of operations.

Revenue Recognition

The Partnership recognizes rental income under operating leases, including rental abatements, lease incentives and contractual fixed increases, if any, from tenants under lease arrangements with minimum fixed and determinable increases on a straight‑line basis over the non‑cancellable term of the related leases when collectability is reasonably assured. The excess of rents recognized over amounts contractually due pursuant to the underlying leases are recorded as deferred rent assets. The excess of rent payments collected over amounts recognized contractually due pursuant to the underlying lease are recorded as prepaid rents. The Partnership accounts for and presents tenant reimbursements as a component of rental revenue in our consolidated income statements in accordance with the new lease standard (“ASC 842”). Tenant reimbursements are recognized as revenue in the period during which the applicable expenses are incurred and the tenant’s obligation to reimburse us arises.

65

Leases obtained by the Partnership through its acquisition and ownership of real property interests are generally cancelable upon 30‑180 days’ notice by the tenants with no significant penalty. The Partnership evaluates whether the lease arrangements economically compel the tenant to not cancel the lease in determining the term of the lease by considering various factors such as cancellation rights, availability of alternative sites, and historical cancellation rates. For cancellable leases where the tenant is not economically compelled to continue the lease, the term of the lease is considered to be the non‑cancellable period with rental abatements and contractual fixed rate increases recorded in the period the amounts become due and payable. Leases obtained through development projects, are generally non‑cancellable for the initial term.

• Wireless Communication – As a result of various factors, including the cancellation rights, ability to find alternative sites, credit risk, and historical cancellation and lease amendment rates, the lease term is generally considered to be the non‑cancellable term of the lease of 30 to 180 days. For these leases, rental abatements and contractual fixed increases are recorded in the period the amounts become due and payable.

• Digital Infrastructure – The lease term is generally non-cancellable.

• Outdoor Advertising and Renewable Power Generation – The lease term is generally considered to be the non‑cancellable term of the remaining portion of the existing term of the lease.

The capitalized above‑market and below‑market lease values are amortized as a decrease or increase, respectively, to rental income over the estimated period the tenant is expected to be leasing the site.

Our ability to accurately estimate the term of our tenant leases is critical to the amount of revenue we recognize.

Results of Operations of our Partnership

Segments

In connection with the sale of our European outdoor advertising portfolio, an evaluation of segment reporting thresholds resulted in changes in our segment presentation for all prior periods presented. As of June 30, 2020, we conduct business through four reportable business segments: Wireless Communication, Digital Infrastructure, Outdoor Advertising and Renewable Power Generation. Our reportable segments are strategic business units that offer different products and services. They are commonly managed, as all four businesses require similar marketing and business strategies. We evaluate our segments based on revenue because substantially all of our tenant lease arrangements are triple net or effectively triple net. We believe this measure provides investors relevant and useful information because it is presented on an unlevered basis.

Results of Operations

Our results of operations for all periods presented were affected by the sale of the European outdoor advertising portfolio on June 17, 2020, other asset sales in 2019, formation of the unconsolidated JV on September 24, 2018, and acquisitions made during the years ended December 31, 2020, 2019 and 2018. As of December 31, 2020 and 2019, we had 1,986 and 2,025 available tenant sites, respectively.

Rental Revenue

Rental revenue increased $5.1 million primarily due to $3.6 million increase during the year ended December 31, 2020 attributable to digital infrastructure acquisitions in 2020 and $1.8 million increase attributable to the full year of rental revenue in 2020 for tenant sites acquired during 2019, offset by $0.3 million of decline in outdoor advertising rental revenue. Revenue generated in 2020 from our wireless communication, digital infrastructure, outdoor advertising and renewable power generation segments was $25.7 million, $9.9, million, $15.2 million and $8.1 million or 43%, 17%, 26% and 14% of total rental revenue, respectively, compared to $25.5 million, $4.2 million, $15.5 million and $8.5 million or 47%, 8%, 29% and 16% of total rental revenue, respectively, during 2019. The occupancy rates in our wireless communication, digital infrastructure, outdoor advertising and renewable power generation segments were 92%, 100%, 96% and 100%, respectively, as of December 31, 2020 compared to 93%, 100%, 97% and 100%, respectively, as of December 31, 2019. Additionally, our effective monthly rental rates per tenant site for wireless communication, digital infrastructure, outdoor advertising and renewable power generation segments were $2,013, $82,006, $1,907 and $9,611, respectively, during 2020 compared to $1,953, $62,761, $1,953 and $9,214, respectively, during 2019.

Property Operating

Property operating expenses increased $0.4 million during 2020 compared to 2019 primarily due to an increase in rent expense on assets subject to a ground lease payment. Substantially all of our tenant sites are leased to tenants under triple net or effectively triple net lease arrangements, which require the tenant or the underlying property owner to pay all utilities, property taxes, insurance and repair and maintenance costs. As we deploy our smart enabled infrastructure solutions and other projects, we may incur additional operating expenses associated with ground lease payments and other operating expenses.

67

General and Administrative

General and administrative expenses decreased $0.5 million during 2020 compared to 2019, primarily due to a decrease in legal related expenses. Under our Amended Partnership Agreement, we are required to reimburse our general partner and its affiliates for all costs and expenses that they incur on our behalf for managing and controlling our business and operations. Except to the extent specified under our Omnibus Agreement, our general partner determines the amount of these expenses and such determinations must be made in good faith under the terms of the Amended Partnership Agreement. On January 30, 2019, we amended the Omnibus Agreement and agreed to reimburse Landmark for expenses related to certain general and administrative services that Landmark will provide to us in support of our business, subject to a quarterly cap equal to 3% of our revenue during the current calendar quarter. Under the amended Omnibus Agreement, this cap on expenses will last until the earlier to occur of: (i) the date on which our revenue for the immediately preceding four consecutive fiscal quarters exceeded $120 million and (ii) November 19, 2021. The full amount of general and administrative expenses incurred is reflected on our income statements and the amount in excess of the cap that is reimbursed is reflected on our financial statements as a capital contribution from Sponsor rather than as a reduction of our general and administrative expenses, except for expenses that would otherwise be allocated to us, which are not included in the amount of general and administrative expenses. For the years ended December 31, 2020 and 2019, Landmark reimbursed us $3.0 million and $3.7 million, respectively, for expenses related to certain general and administrative expenses that exceeded the cap. Included in the total general and expenses reimbursement from Sponsor is $0.3 million, respectively, of management fees related to our unconsolidated joint venture that is not subject to the cap and is treated as a capital contribution from Sponsor. Additionally, indemnification of $0.4 million related to property taxes is included in capital contributions from Sponsor on the Consolidated Statements of Equity and Mezzanine Equity for 2019.

Acquisition-Related

Acquisition-related expenses are third party fees and expenses related to acquiring an asset and include survey, title, legal and other items as well as legal and financial advisor expenses associated with business acquisitions or unsuccessful asset acquisitions.

Depreciation and Amortization

Depreciation and amortization expense increased $3.0 million during 2020 compared to 2019 primarily as a result of acquisitions and the deployment of two stealth towers, 112 DART kiosks and other assets placed in service in 2020.

Impairments

Impairments decreased $2.0 million during 2020 compared to 2019, primarily due to five lease terminations and one non-lease renewal in our wireless and outdoor advertising segments for $0.3 million during the year ended December 31, 2020, compared to impairment charges related to certain construction in progress contracts and eight lease terminations in our wireless communication and outdoor advertising segments for $2.3 million during the year ended December 31, 2019.  

Interest and Other Income

Interest and other income decreased $0.1 million during 2020 compared to 2019 primarily as a result of the sale of investments in receivables during the year ended December 31, 2019. Interest income on receivables is generated from our wireless communication, outdoor advertising, and renewable power generation segments.

Interest Expense

Interest expense decreased $0.2 million during 2020 compared to 2019, primarily due to lower interest rates during 2020 compared to 2019.

68

Loss on Early Extinguishment of Debt

In connection with the issuance of the 2019 Secured Notes, the Partnership repaid in full the 2016 Secured Notes by $108 million. The unamortized balance of the deferred loan costs totaling $1.2 million and a $1.0 million make-whole payment were recorded as a loss on extinguishment of debt during the year ended December 31, 2020.

Unrealized Loss on Derivatives

We mitigated exposure to fluctuations in interest rates on existing variable rate debt by entering into swap contracts that fixed the floating LIBOR rate. These interest rate swap agreements extend through and beyond the term of the Partnership’s existing credit facility. The swap contracts were adjusted to fair value at each period end. The unrealized loss recorded for the year ended December 31, 2020 and unrealized loss for the year ended December 31, 2019, reflects the change in fair value of these contracts during those periods. In connection with the sale of the European outdoor advertising portfolio, the Partnership used proceeds from the sale to terminate existing swaps including the GBP interest rate swap agreement for a total of approximately $7.6 million.

Equity Income from Unconsolidated Joint Venture

Equity income from unconsolidated joint venture increased $0.8 million during the year ended December 31, 2020 compared to 2019. Under the equity method, the investment is initially recorded at fair value and subsequently adjusted for additional distributions and the Partnership’s proportionate share of equity in the JV’s income. The Partnership recognizes its proportionate share of the ongoing income or loss of the unconsolidated JV as equity income from unconsolidated JV on the consolidated statements of operations.

Gain on Sale of Real Property Interests

During the year ended December 31, 2019, the Partnership recognized gain on sale of real property interests of $18.0 million related to
the sale of real property interests to third parties during the year ended December 31, 2019. There was no gain on sale of real property interests recognized during the year ended December 31, 2020.

Income Tax Expense (Benefit)

During the year ended December 31, 2020, the Partnership recorded a net tax benefit of $0.4 million as a result of an increase to deferred tax assets related to a higher US state effective tax rate and generated net operating losses. During the year ended December 31, 2019, the Partnership recorded a gain on sale of assets in our taxable subsidiary of $11.7 million, resulting in a $3.0 million income tax expense related to the gain.

Income (Loss) from Discontinued Operations, Net of Tax

On June 17, 2020, the Partnership sold its European outdoor advertising portfolio for a purchase price of £95 million and recognized a total gain on sale of $15.5 million. The sale of the European outdoor advertising portfolio met the criteria as discontinued operations in June 2020. As a result, we reclassified the operating results of the European outdoor advertising portfolio and gain on sale to discontinued operations and excluded these amounts from income from continuing operations for all periods presented on the consolidated statements of operations.

Rental Revenue

Rental revenue decreased $7.7 million primarily due to the formation of the unconsolidated JV and 2019 sales of real property interests. Rental revenue for the year ended December 31, 2018 includes $10.0 million of rental revenue generated from the assets contributed to the JV prior to the date of the transaction and $2.0 million of rental revenue generated from assets sold in 2019. The decrease in rental revenue during the year ended December 31, 2019 was offset by $2.7 million increase in rental revenue as a result of lease amendments and contractual lease escalators in 2019, as well as $0.8 million of rental revenue attributed to assets acquired in 2019 and $0.8 million of rental revenue due to the full year of rental revenue in 2019 for tenant sites acquired during 2018. On September 24, 2018, the Partnership completed the formation of the unconsolidated JV. The Partnership contributed 545 wireless communication assets to the JV along with the associated liabilities. The Partnership does not control the unconsolidated JV and therefore, accounts for its investment in the unconsolidated JV using the equity method of accounting prospectively upon formation of the unconsolidated JV. Revenue generated in 2019 from our wireless communication, digital infrastructure, outdoor advertising and renewable power generation segments was $25.5 million, $4.2 million, $15.5 million and $8.5 million or 47%, 8%, 29% and 16% of total rental revenue, respectively, compared to $34.6 million, $3.3 million, $15.5 million and $8.1 million, or 57%, 5%, 25% and 13% of total rental revenue, respectively, during 2018. The occupancy rates in our wireless communication, digital infrastructure, outdoor advertising and renewable power generation segments were 93%, 100%, 97% and 100% respectively, as of December 31, 2019 compared to 94%, 100%, 98% and 100%, respectively, as of December 31, 2018. Additionally, our effective monthly rental rates per tenant site for wireless communication, digital infrastructure, outdoor advertising and renewable power generation segments were $1,953, $62,761, $1,953 and $9,214, respectively, during 2019 compared to $1,926, $53,301, $2,118 and $9,148, respectively, during 2018.

Property Operating

Property operating expenses increased $0.6 million during 2019 compared to 2018 primarily due to an increase in property taxes as a result of an increase in fee simple properties and rent expense on assets subject to a ground lease payment. Substantially all of our tenant sites are leased to tenants under triple net or effectively triple net lease arrangements, which require the tenant or the underlying property owner to pay all utilities, property taxes, insurance and repair and maintenance costs. As we deploy our smart enabled infrastructure solution and other projects, we may incur additional operating expenses associated with ground lease payments and other operating expenses.

70

General and Administrative

General and administrative expenses increased $0.7 million during 2019 compared to 2018, primarily due an increase in accounting and legal related expenses. Under our Amended Partnership Agreement, we are required to reimburse our general partner and its affiliates for all costs and expenses that they incur on our behalf for managing and controlling our business and operations. Except to the extent specified under our Omnibus Agreement, our general partner determines the amount of these expenses and such determinations must be made in good faith under the terms of the Amended Partnership Agreement. On January 30, 2019, we amended the Omnibus Agreement and agreed to reimburse Landmark for expenses related to certain general and administrative services that Landmark will provide to us in support of our business, subject to a quarterly cap equal to 3% of our revenue during the current calendar quarter. Under the amended Omnibus Agreement, this cap on expenses will last until the earlier to occur of: (i) the date on which our revenue for the immediately preceding four consecutive fiscal quarters exceeded $120 million and (ii) November 19, 2021. The full amount of general and administrative expenses incurred is reflected on our income statements and the amount in excess of the cap that is reimbursed is reflected on our financial statements as a capital contribution from Sponsor rather than as a reduction of our general and administrative expenses, except for expenses that would otherwise be allocated to us, which are not included in the amount of general and administrative expenses. For the years ended December 31, 2019 and 2018, Landmark reimbursed us $3.7 million and $2.8 million, respectively, for expenses related to certain general and administrative expenses that exceeded the cap. Included in the total general and expenses reimbursement from Sponsor is $0.3 million of management fees related to our unconsolidated joint venture that is not subject to the cap and is treated as a capital contribution from Sponsor. Additionally, indemnification of $0.4 million related to property taxes is included in capital contributions from Sponsor on the Consolidated Statements of Equity and Mezzanine Equity for 2019.

Depreciation and Amortization

Depreciation and amortization expense decreased $2.3 million during 2019 compared to 2018 as a result of having a greater number of average tenant sites during 2018 compared to 2019. Amortization of investments in real property rights with finite useful lives and in‑place lease values to decreased as a result of contributing assets to the unconsolidated JV. Depreciation and amortization expense for the year ended December 31, 2018 included $2.6 million of amortization expense generated from the JV assets during the year ended December 31, 2018.

Impairments

Impairments increased $0.7 million during 2019 compared to 2018, primarily due to impairment charges related to certain construction in progress contracts and eight lease terminations in our wireless communication and outdoor advertising segments for $2.3 million during the year ended December 31, 2019, compared to impairment charges related to 16 investments in receivables in our wireless communication segment and six lease termination in our wireless communication and outdoor advertising segments for $1.4 million during the year ended December 31, 2018. Landmark indemnified the Partnership for the $1.0 million impairment of investments in receivables and certain real property interests which is reflected as a deemed capital contribution.

Interest and Other Income

Interest and other income decreased $0.8 million during 2019 compared to 2018 primarily as a result of the sale of investments in receivables during the year ended December 31, 2019. Interest income on receivables is generated from our wireless communication, outdoor advertising, and renewable power generation segments. We expect interest and other income to decrease in future periods as a result of the sale of $8.3 million in investments in receivables during the year ended December 31, 2019.

Interest Expense

Interest expense decreased $6.8 million during 2019 compared to 2018, primarily due to lower average debt balance of approximately $395 million for the year ended December 31, 2019 compared to an average debt balance of approximately $442.6 million during the year ended December 31, 2018.

Loss on Early Extinguishment of Debt

In connection with the Third Amended and Restated Credit Facility on November 15, 2018, a portion of the unamortized balance of the deferred loan costs totaling $0.2 million was recorded as a loss on extinguishment of debt during the year ended December 31, 2018.

Unrealized Gain (Loss) on Derivatives

We mitigated exposure to fluctuations in interest rates on existing variable rate debt by entering into swap contracts that fixed the floating LIBOR rate. These interest rate swap agreements extend through and beyond the term of the Partnership’s existing credit facility. The swap contracts were adjusted to fair value at each period end. The unrealized loss recorded for the year ended December 31, 2019 and unrealized gain for the year ended December 31, 2018, reflects the change in fair value of these contracts during those periods.

71

Equity Income from Unconsolidated Joint Venture

Equity income from unconsolidated joint venture increased $0.3 million during the year ended December 31, 2019 compared to 2018 due to the formation of the JV on September 24, 2018. The Partnership accounts for its 50.01% investment in the unconsolidated JV using the equity method of accounting. Under the equity method, the investment is initially recorded at fair value and subsequently adjusted for additional distributions and the Partnership’s proportionate share of equity in the JV’s income. The Partnership recognizes its proportionate share of the ongoing income or loss of the unconsolidated JV as equity income from unconsolidated JV on the consolidated statements of operations.

Gain on Sale of Real Property Interests

During the year ended December 31, 2019, the Partnership recognized gain on sale of real property interests of $18.0 million related to the sale of real property interests to third parties during the year ended December 31, 2019. During the year ended December 31, 2018, we recognized a gain on contribution of real property interests of $100 million in connection with the formation of the unconsolidated JV in which 545 tenant sites were contributed to the JV by the Partnership.

Income Tax Expense

Income tax expense increased $3.0 million during the year ended December 31, 2019 compared to the year ended December 31, 2018 primarily due to a gain on sale of assets in our taxable subsidiary of $11.7 million, resulting in a $3.0 million income tax expense related to the gain.

Income (Loss) from Discontinued Operations, Net of Tax

On June 17, 2020, the Partnership sold its European outdoor advertising portfolio for a purchase price of £95 million and recognized a total gain on sale of $15.5 million. The sale of the European outdoor advertising portfolio met the criteria as discontinued operations in June 2020. As a result, we reclassified the operating results of the European outdoor advertising portfolio and gain on sale to discontinued operations and excluded these amounts from income from continuing operations for all periods presented on the consolidated statements of operations.

Liquidity and Capital Resources

Our short‑term liquidity requirements will consist primarily of funds to pay for operating expenses, acquisitions and developments and other expenditures directly associated with our assets, including:

• interest expense on our revolving credit facility;

• interest expense and principal payments on our secured notes;

• general and administrative expenses;

• acquisitions of real property interests;

• capital expenditures for infrastructure developments; and

• distributions to our common and preferred unitholders.

We intend to satisfy our short‑term liquidity requirements primarily through cash flow from operating activities and through borrowings available under our revolving credit facility. We may also satisfy our short-term liquidity requirements through the issuance of additional equity, asset dispositions, formation of joint ventures, amending our existing revolving credit facility to increase the available commitments or refinancing some of the outstanding borrowings under our existing credit facility through securitizations or other long-term debt arrangements. Our ability to access capital on favorable terms as well as to use cash from operations to continue to meet our liquidity needs, all of which are highly uncertain and cannot be predicted, could be affected by various risks and uncertainties, including, but not limited to, the effects of the COVID-19 pandemic and other risks detailed in Part I, Item 1A titled “Risk Factors”. Access to capital markets impacts our cost of capital and ability to refinance indebtedness, as well as our ability to fund future acquisitions and development through the issuance of additional securities or secured debt. Credit ratings impact our ability to access capital and directly impact our cost of capital as well. The Partnership has a universal shelf registration statement on file with the SEC, effective January 30, 2020, under which we have the ability to issue and sell common and preferred units representing limited partner interests in us and debt securities up to an aggregate amount of $750.0 million.

72

On January 22, 2021, the General Partner’s board of directors approved a quarterly distribution of $0.20 per common unit for the quarter ended December 31, 2020. The current quarter distribution equates to approximately $5.1 million per quarter, or $20.4 million per year in the aggregate, based on the number of common units outstanding as of February 2, 2021. As a result of the unprecedented economic conditions, we will focus on repaying borrowings under our revolving credit facility, preserving liquidity and capital for any potential impact to our business and positioning the Partnership to take advantage of any prospective market opportunities. We do not have a legal obligation to pay this distribution or any other distribution except to the extent we have available cash as defined in our Amended Partnership Agreement.

We intend to pay a quarterly Series A and Series B Preferred Unit distribution of 8.0% and 7.9%, respectively, which equates to approximately $2.2 million per quarter, or approximately $8.8 million per year in the aggregate based on the number of Preferred Units outstanding as of February 1, 2021. We intend to pay a quarterly Series C Preferred Units distribution of a rate equal to the greater of (i) 7.00% per annum, and (ii) the sum of (a) three-month LIBOR as calculated on each applicable date of determination and (b) 4.698% per annum, based on the $25.00 liquidation preference per Series C Preferred Unit. As of December 31, 2020, there were 1,982,700 Series C Preferred Units outstanding. The Preferred Unit distributions are cumulative from the date of original issuance and will be payable quarterly in arrears.

The amount of future distributions to unitholders will depend on our results of operations, financial condition, capital requirements and will be determined by the General Partner’s Board of Directors on a quarterly basis. The Partnership expects to rely on external financing sources, including equity and debt issuances, to fund expansion capital expenditures and future acquisitions. However, the Partnership may use operating cash flows to fund expansion capital expenditures or acquisitions, which could result in subsequent borrowings under the revolving credit facility to pay distributions or fund other short-term working capital requirements.  

The requirements under our Partnership Agreement for the conversion of all the subordinated units into common units were satisfied upon the payment of our quarterly cash distribution on February 14, 2018. Therefore, effective February 15, 2018, all of our subordinated units which are owned by Landmark, were converted on a one-for-one basis into common units. The conversion of subordinated units does not impact the amount of cash distributions or total number of outstanding units.

(1) The General Partner irrevocably waived its right to receive the incentive distribution and incentive allocations related to the respective quarterly distribution.

(2) The first distribution declared by the Partnership for the Series C Preferred Units was prorated for the 43-day period following the closing of the issuance on April 2, 2018. The distribution was paid on May 15, 2018 to unitholders of record as of May 1, 2018.

74

As of December 31, 2020, we had $493.9 million of total outstanding indebtedness. As of February 18, 2021, the Partnership had $214.2 million of outstanding borrowings on our revolving credit facility, and we had $235.8 million of undrawn borrowing capacity (including standby letter of credit arrangements of $5.8 million), subject to compliance with certain covenants, under our revolving credit facility.

Our long‑term liquidity needs consist primarily of funds necessary to pay for acquisitions, developments and scheduled debt maturities. We intend to satisfy our long‑term liquidity needs through cash flow from operations, joint ventures, and through the issuance of additional equity and debt.

Cash Flows

The following table summarizes the historical cash flow of the Partnership for the years ended December 31, 2020 and 2019 (in thousands):

	Year Ended December 31,
	2020			2019			2018
Net cash provided by operating activities	$	42,180		$	31,663		$	31,256
Net cash used in investing activities		(44,070	)		(52,906	)		(37,533	)
Net cash provided by (used in) financing activities		3,429			26,460			(13,652	)

Comparison of year ended December 31, 2020 to year ended December 31, 2019

Net cash provided by operating activities.  Net cash provided by operating activities increased $10.5 million to $42.2 million for the year ended December 31, 2020 compared to $31.7 million for the year ended December 31, 2019. The increase is primarily attributable to asset acquisitions and the timing of prepaid expenses, other assets and payments of accounts payable and accrued liabilities, which is partially offset by a reduction in return on investment in the unconsolidated joint venture.

Net cash used in investing activities.  Net cash used in investing activities was $44.1 million for the year ended December 31, 2020 compared to $52.9 million for the year ended December 31, 2019. The change in net cash used in investing activities was primarily due to cash used for asset acquisitions and development activities during the years ended December 31, 2020 and 2019, partially offset by the proceeds received from the sale of the European outdoor advertising portfolio during the year ended December 31, 2020 compared to the proceeds received from the sale of real property interests in 2019.

Net cash provided by financing activities.  Net cash provided by financing activities was $3.4 million for the year ended December 31, 2020 compared to net cash provided by financing activities of $26.5 million for the year ended December 31, 2019. The change in net cash provided by financing activities was primarily attributable to $25.6 million in net payments on the revolving credit facility and secured notes, $7.6 million of payments on the settlement of derivatives and $1.8 million of cash used for deferred loan costs offset by $12.2 million decrease in distributions and $0.2 million in proceeds from equity offerings.

Comparison of year ended December 31, 2019 to year ended December 31, 2018

Net cash provided by operating activities.  Net cash provided by operating activities increased $0.4 million to $31.7 million for the year ended December 31, 2019 compared to $31.3 million for the year ended December 31, 2018. The increase is primarily attributable to the timing of prepaid expenses, other assets and payments of accounts payable and accrued liabilities.

Net cash used in investing activities.  Net cash used in investing activities was $52.9 million for the year ended December 31, 2019 compared to $37.5 million for the year ended December 31, 2018. The change in cash used in investing activities was primarily due to the proceeds received from the sale of real property interests in 2019 compared to proceeds received related to the formation of the unconsolidated joint venture on September 24, 2018.

Net cash provided by (used in) financing activities.  Net cash provided by financing activities was $26.5 million for the year ended December 31, 2019 compared to net cash used in financing activities of $13.7 million for the year ended December 31, 2018. The change in net cash provided by (used in) financing activities was primarily attributable to the net increase of $53.3 million in proceeds from the net borrowings from the revolving credit facility and secured notes and the net decrease of $9.8 million used in deferred loan costs offset by net decrease of $43.4 million in proceeds from equity offerings during the year ended December 31, 2019 compared to the year ended December 31, 2018. Additionally, the difference between the cost and the sales price of the Drop-down Acquisition completed during the year ended December 31, 2018 is treated as a distribution to Landmark.

Revolving Credit Facility

Our revolving credit facility will mature on November 15, 2023 and is available for working capital, capital expenditures, permitted acquisitions and general corporate purposes, including distributions. On November 15, 2018, the Partnership completed its Third Amended and Restated Credit Facility and obtained commitments from a syndicate of banks with initial borrowing commitments of $450.0 million for five-years. Additionally, borrowings up to $75.0 million may be denominated in GBP, Euro, Australian dollar and Canadian dollar. In June 2020, the Partnership used proceeds from the sale of the European outdoor advertising portfolio and available cash to repay borrowings totaling $115 million on its revolving credit facility, including the £40.5 million of GBP denominated borrowings. Substantially all of our assets, excluding equity in and assets of unrestricted subsidiaries, after-acquired real property (other than real property that is acquired from affiliate funds and is subject to a mortgage), and other customary exclusions, are pledge (or secured by mortgages), as collateral under our revolving credit facility.

Our revolving credit facility contains various covenants and restrictive provisions that limit our ability (as well as the ability of our restricted subsidiaries) to, among other things:

• incur or guarantee additional debt;

• make distributions on or redeem or repurchase equity;

• make certain investments and acquisitions;

• incur or permit to exist certain liens;

• enter into certain types of transactions with affiliates;

• merge or consolidate with another company;

• transfer, sell or otherwise dispose of assets or enter into certain sale‑leaseback transactions; and

• enter into certain restrictive agreements or amend or terminate certain material agreements.

Our revolving credit facility also requires compliance with certain financial covenants as follows:

• a leverage ratio of not more than 8.0 to 1.0; and

• an interest coverage ratio of not less than 2.0 to 1.0.

In addition, our revolving credit facility contains events of default including, but not limited to (i) event of default resulting from our failure or the failure of our restricted subsidiaries to comply with covenants and financial ratios, (ii) the occurrence of a change of control (as defined in the credit agreement), (iii) the institution of insolvency or similar proceedings against us or our restricted subsidiaries, (iv) the occurrence of a default under any other material indebtedness (as defined in the credit agreement) we or our restricted subsidiaries may have and (v) any one or more collateral documents ceasing to create a valid and perfected lien on collateral (as defined in the credit agreement). Upon the occurrence and during the continuation of an event of default, subject to the terms and conditions of the credit agreement, the lenders may declare any outstanding principal of our revolving credit facility debt, together with accrued and unpaid interest, to be immediately due and payable and may exercise the other remedies set forth or referred to in the credit agreement and the other loan documents.

Loans under the revolving credit facility bear interest at a rate equal to LIBOR, plus a spread ranging from 1.75% to 2.25% (determined based on leverage levels). As of December 31, 2020, the applicable spread was 2.25%.

Additionally, under the revolving credit facility we will be subject to an annual commitment fee (determined based on leverage levels) associated with the available undrawn capacity subject to certain restrictions. As of December 31, 2020, the applicable annual commitment rate used was 0.20%.

As of December 31, 2020, the Partnership had $214.2 million of total outstanding indebtedness under the revolving credit facility with $235.8 million available under the revolving credit facility (including a standby letter of credit arrangement of $5.8 million), subject to compliance with certain covenants. The Partnership was in compliance with all covenants under its revolving credit facility as of December 31, 2020. As of February 18, 2021, the Partnership had $214.2 million of outstanding borrowings on our revolving credit facility, and we had $235.8 million of undrawn borrowing capacity (including standby letter of credit arrangements of $5.8 million), subject to compliance with certain covenants, under our revolving credit facility.

76

Secured Notes

On January 15, 2020, certain subsidiaries of the Partnership entered into a master note purchase and participation agreement (“MNPPA”) pursuant to which such subsidiaries issued and sold an initial $170 million aggregate principal amount of 3.90% series A senior secured notes in a private placement (the “2019 Secured Notes”). The 2019 Secured Notes mature on January 14, 2027 and include an interest-only initial term of three years. The net proceeds were used to repay in full the 2016 Secured Notes by $108 million and the revolving credit facility by $59 million. In connection with the issuance of the senior secured notes, the Partnership obtained a standby letter of credit arrangement totaling $3.4 million.

On April 24, 2018, the Partnership entered into a note purchase and private shelf agreement pursuant to which the Partnership agreed to sell an initial $43.7 million aggregate principal amount of 4.38% Senior Secured Notes, in a private placement. The 4.38% Senior Secured Notes are obligations of certain special purpose subsidiaries of the Partnership, including the issuer of the 4.38% Senior Secured Notes, LMRK PropCo SO LLC (the “4.38% Senior Secured Notes Issuer”), and are not obligations of the Partnership or any of its other subsidiaries (including the obligors with respect to the 4.38% Senior Secured Notes). The assets and credit of such obligors are not available to satisfy the debts and obligations of the Partnership or any of its other affiliates (other than the obligors with respect to the 4.38% Senior Secured Notes). In connection with the issuance of the 4.38% Senior Secured Notes, the Partnership obtained a standby letter of credit arrangement totaling $2.4 million.

On November 30, 2017, the Partnership completed the 2017 Securitization involving certain outdoor advertising sites and related property interests owned by certain special purpose subsidiaries of the Partnership, through the issuance of the 2017 Secured Notes, in an aggregate principal amount of $80.0 million. The 2017 Secured Notes are obligations of certain special purpose subsidiaries of the Partnership, including the issuer of the 2017 Secured Notes, LMRK Issuer Co. 2 LLC, and are not obligations of the Partnership or any of its other subsidiaries (including the obligors with respect to the 2016 and 2019 Secured Notes). The assets and credit of such obligors are not available to satisfy the debts and obligations of the Partnership or any of its other affiliates (other than the obligors with respect to the 2017 Secured Notes).

The secured notes described above were issued in separate classes as indicated in the table below. The Class B notes of the Series 2017-1 are subordinated in right of payment to the Class A notes of such series.

	Initial Principal					Anticipated
Series and Class	Balance (in thousands)		Note Rate			Repayment Date
4.38% senior secured notes	$	43,702		4.38	%	June 30, 2036
Series 2019-1 Class A	$	170,000		3.90	%	January 14, 2027
Series 2017-1 Class A	$	62,000		4.10	%	November 15, 2022
Series 2017-1 Class B	$	18,000		3.81	%	November 15, 2022

The Secured Notes are each secured by (1) mortgages and deeds of trust on substantially all of the tenant sites and their operating cash flows, (2) a security interest in substantially all of the personal property of the obligors (as defined in the applicable indenture), and (3) the rights of the obligors under a management agreement. Under the terms of the applicable indenture, the obligors will be permitted to issue additional notes under certain circumstances, including so long as the debt service coverage ratio (“DSCR”) of the issuer is at least 1.5 to 1.0 for the 2019 Secured Notes, 2.0 to 1.0 for the 2017 Secured Notes and at least 1.1 to 1.0 for the 4.38% Senior Secured Notes

Under the terms of the applicable indenture, amounts due under the Secured Notes, as applicable, will be paid solely from the cash flows generated from the operation of the Secured Tenant Site Assets, as applicable, which must be deposited into reserve accounts, and thereafter distributed solely pursuant to the terms of the applicable indenture. On a monthly basis, after payment of all required amounts under the applicable indenture, subject to the conditions described in Note 10, Debt, the excess cash flows generated from the operation of such assets are released to the Partnership. As of December 31, 2020, $3.2 million was held in such reserve accounts which are classified as Restricted Cash on the accompanying consolidated balance sheets.

Certain information with respect to the Secured Notes is set forth in Note 10, Debt. The DSCR is generally calculated as the ratio of annualized net cash flow (as defined in the applicable indenture) to the amount of interest, servicing fees and trustee fees required to be paid over the succeeding 12 months on the principal amount of the Secured Notes, as applicable, that will be outstanding on the payment date following such date of determination.

Each indenture includes covenants customary for notes issued in rated securitizations. Among other things, the related obligors are prohibited from incurring other indebtedness for borrowed money or further encumbering their assets (as defined in the applicable agreement) and the organizational documents of the related obligors were amended to contain certain provisions consistent with rating agency securitization criteria for special purposes entities, including that the applicable issuer and guarantor maintain independent directors. As of December 31, 2020, the applicable obligors were in compliance with all financial covenants under the Secured Notes.

Shelf Registrations

On December 4, 2019, the Partnership filed a universal shelf registration statement on Form S-3 with the SEC. The shelf registration statement was declared effective by the SEC on January 30, 2020 and permits us to issue and sell, from time to time, common and preferred units representing limited partner interests in us, and debt securities up to an aggregate amount of $750.0 million.

Preferred Equity Offerings

On April 2, 2018, the Partnership completed a public offering of 2,000,000 Series C Floating-to-Fixed Rate Cumulative Perpetual Redeemable Convertible Preferred Units (“Series C Preferred Units”), representing limited partner interest in the Partnership, at a price of $25.00 per unit. We received net proceeds of approximately $47.5 million after deducting underwriters’ discounts and offering expenses paid by us of $2.5 million. We used substantially all net proceeds to repay a portion of the borrowings under our revolving credit facility.

Distributions on the Series C Preferred Units will be the 15th day of February, May, August and November of each year. The prorated initial distribution on the Series C Preferred Units was paid on May 15, 2018 in an amount equal to $0.2090 per Series C Preferred Unit. Distributions for the Series C Preferred Units will accrue from, and including the date of original issuance, to, but excluding, May 15, 2025, at an annual rate equal to the greater of (i) 7.00% per annum and (ii) the sum of (a) the three-month LIBOR as calculated on each applicable date of determination and (b) 4.698% per annum, based on the $25.00 liquidation preference per Series C Preferred Unit. On and after May 15, 2025, distributions on the Series C Preferred Units will accrue at 9.00% per annum of the $25.00 liquidation preference per Series C Preferred Unit (equal to $2.25 per Series C Preferred Unit per annum). The Partnership shall have the option to redeem the Series C Preferred Units, in whole or in part, on or after May 20, 2025 at the liquidation preference of $25.00 per Series C Preferred Unit, plus an amount equal to all accumulated and unpaid distributions thereon to the date of redemption, whether or not declared.

ATM Programs

On February 28, 2020, the Partnership replaced the 2019 Common Unit at-the-market offering program with a 2020 Common Unit at-the-market offering program pursuant to which we may sell, from time to time, Common Units having an aggregate offering price of up to $50.0 million pursuant to our previously filed and effective registration statement on Form S-3. On February 28, 2020, the Partnership replaced the 2019 Series A ATM Program and established a new Series A Preferred Unit at-the-market offering program (the “2020 Series A ATM Program”) pursuant to which we may sell, from time to time, Series A Preferred Units having an aggregate offering price of up to $50.0 million pursuant to our previously filed and effective registration statement on Form S-3. On February 28, 2020, the Partnership replaced the Series B ATM Program and established a new Series B Preferred Unit at-the-market offering program (the “2020 Series B ATM Program”) pursuant to which we may sell, from time to time, Series B Preferred Units having an aggregate offering price of up to $50.0 million pursuant to our previously filed and effective registration statement on Form S-3. We intend to use the net proceeds from any sales pursuant to the ATM Programs for general partnership purposes, which may include, among other things, the repayment of indebtedness and to potentially fund future acquisitions.

During the year ended December 31, 2020, the Partnership issued a total of 109,724 Common Units, 23,287 Series A Preferred Units and 84,139 Series B Preferred Units under the 2019 ATM programs generating total proceeds of approximately $4.5 million before issuance costs. During the year ended December 31, 2020, the Partnership issued 43,515 Series A Preferred Units under the 2020 Series A ATM Program, generating proceeds of approximately $1.1 million before issuance costs. There were no Common Units or Series B Preferred Units issued under the 2020 ATM programs.

During the year ended December 31, 2019, the Partnership issued a total of 128,892 Series A Preferred Units and 81,778 Series B Preferred under the ATM Programs generating total proceeds of approximately $5.3 million before issuance costs. For the year ended December 31, 2018, the Partnership issued a total of 27,830 Common Units and 24,747 Series A Preferred Units under the ATM Programs generating total proceeds of approximately $1.1 million before issuance costs.

Off Balance Sheet Arrangements

In connection with the issuance of the 4.38% Senior Secured Notes, the Partnership has a standby letter of credit arrangement totaling $2.4 million. In connection with the issuance of the 2019 Secured Notes, the Partnership has a standby letter of credit arrangement totaling $3.4 million. As of December 31, 2020, there were no amounts drawn on the standby letter of credit.

The Partnership does not have any other off balance sheet arrangements.

Inflation

The majority of our tenant lease arrangements are triple net or effectively triple net and provide for fixed‑rate escalators or rent escalators tied to increases in the consumer price index. We believe that inflationary increases may be at least partially offset by the contractual rent increases and our tenants’ (or the underlying property owners’) obligations to pay taxes and expenses under our triple net and effectively triple net lease arrangements. We do not believe that inflation has had a material impact on our historical financial position or results of operations.

Newly Issued Accounting Standards

For a discussion of newly issued accounting standards updates, see Note 2, Basis of Presentation and Summary of Significant Accounting Policies, within the Notes to the Consolidated Financial Statements in Item 15., “Exhibits, Financial Statement Schedules.”

ITEM 7A. Quantitative and Qualitative Disclosures About Market Risk

Our future income, cash flow and fair values relevant to financial instruments are impacted by prevailing market interest rates. Market risk refers to the risk of loss from adverse changes in market prices and interest rates. In the future, we may continue to use derivative financial instruments to manage, or hedge, interest rate risks related to our borrowings. Our primary market risk exposure is interest rate risk with respect to our expected indebtedness. The outbreak of COVID-19 has significantly adversely impacted global economic activity and has contributed to significant volatility and negative pressure in financial markets and added market risk. The impacts of a potential worsening of global economic conditions and the continued disruptions to, and volatility in, the credit and financial markets, consumer spending as well as other unanticipated consequences remain unknown.

Interest Rate Risk

We are exposed to risks arising from rising interest rates. As of December 31, 2020, our revolving credit facility had an outstanding balance of $214.2 million. As of December 31, 2020, we have hedged $150 million of the LIBOR rate on our revolving credit facility through interest rate swap agreements. Additional borrowings under our revolving credit facility will have variable LIBOR‑based rates and will fluctuate based on the underlying LIBOR rate. On November 15, 2018, the Partnership completed its Third Amended and Restated Credit Facility that allows for borrowings in GBP LIBOR, subject to certain limitations. In connection with the sale of the European outdoor advertising portfolio, the Partnership used proceeds from the sale and available cash to repay borrowings totaling $115 million on the revolving credit facility, including the £40.5 million of GBP denominated borrowings, and terminate USD interest rate swaps with a notional value of $145 million and a GBP denominated interest rate swap agreement with a notional value of £38 million for approximately $7.6 million.

The distributions on the Series C Preferred Units are based on a rate equal to the greater of (i) 7.00% per annum, and (ii) the sum of (a) three-month LIBOR as calculated on each applicable date of determination and (b) 4.698% per annum, based on the $25.00 liquidation preference per Series C Preferred Unit. As of December 31, 2020, there were 1,982,700 Series C Preferred Units outstanding.

Interest risk amounts represent our management’s estimates and were determined by considering the effect of hypothetical interest rates on our financial instruments. These analyses do not consider the effect of any change in overall economic activity that could occur in that environment. Further, in the event of a change of that magnitude, we may take actions to further mitigate our exposure to the change. However, due to the uncertainty of the specific actions that would be taken and their possible effects, these analyses assume no changes in our financial structure.

Rising interest rates could limit our ability to refinance our debt when it matures or cause us to pay higher interest rates upon refinancing and increase interest expense on refinanced indebtedness. We intend to hedge interest rate risks related to a portion of our borrowings over time by means of interest rate swap agreements or other arrangements.

79

Foreign Currency Risk

As we expand in international markets, we are exposed to market risk from changes in foreign currency exchange rates. Approximately 3%, 2% and 2% of rental revenue was denominated in foreign currencies for the years ended December 31, 2020, 2019 and 2018, respectively. In the future, we may utilize derivative instruments, or borrow in local currencies, to manage the risk of fluctuations in foreign currency rates.

In July 2017, the FCA, which regulates LIBOR announced it intends to stop compelling banks to submit rates for the calculation of LIBOR after 2021. As a result, the Federal Reserve Board and the Federal Reserve Bank of New York organized the ARRC which identified the SOFR as its preferred alternative to USD-LIBOR in derivatives and other financial contracts. The Partnership is not able to predict when LIBOR will cease to be available or when there will be sufficient liquidity in the SOFR markets. Any changes adopted by FCA or other governing bodies in the method used for determining LIBOR may result in a sudden or prolonged increase or decrease in reported LIBOR. If that were to occur, our interest payments could change. In addition, uncertainty about the extent and manner of future changes may result in interest rates and/or payments that are higher or lower than if LIBOR were to remain available in its current form. Our revolving credit facility contains fallback language generally consistent with the ARRC’s amendment approach, which provides a streamlined amendment approach for negotiating a benchmark replacement and introduces clarity with respect to the fallback trigger events and an adjustment to be applied to the successor rate. We continue to monitor developments by the ARRC and the potential impact of LIBOR changes on our business.

ITEM 9A. Controls and Procedures

Disclosure Controls and Procedures

As required by Rule 13a-15(b) of the Exchange Act, we have evaluated, under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this report. We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our reports under the Exchange Act, is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and that such information is accumulated and communicated to our management to allow for timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Our disclosure controls and procedures are designed to provide reasonable assurance that the information required to be disclosed by us in reports that we file or submit under the Exchange Act is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure and is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC. Based upon that evaluation, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures were effective as of the end of the period covered by this report at the reasonable assurance level.

Internal Control over Financial Reporting

Management’s Annual Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rule 13a-15(f) and Rule 15d-15(f) under the Exchange Act). Our internal control over financial reporting is a process designed under the supervision of our principal executive officer and principal financial officer to provide reasonable assurance regarding the reliability of financial reporting and the preparation of our financial statements for external purposes in accordance with generally accepted accounting principles.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect fraud or misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

As of December 31, 2020, management assessed the effectiveness of our internal control over financial reporting based on the criteria for effective internal control over financial reporting established in the Internal Control Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on this assessment and those criteria, management determined that we maintained effective internal control over financial reporting as of December 31, 2020.

80

This annual report does not include an attestation report of our registered public accounting firm on our internal control over financial reporting. Management’s report was not subject to attestation by our registered public accounting firm pursuant to the rules of the SEC that permit us to provide only management’s report in this Annual Report.

Changes in Internal Control over Financial Reporting

There has been no change in our internal control over financial reporting that occurred during our last fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting. In response to the COVID-19 pandemic, in mid-March, Landmark shifted its corporate office functions to work remotely. Management has taken measures to ensure that the Partnership’s internal control over financial reporting are materially unchanged during this period.

PART III

ITEM 10. Directors, Executive Officers and Corporate Governance

Management of Landmark Infrastructure Partners LP

We are managed by the directors and executive officers of our general partner, Landmark Infrastructure Partners GP LLC. Our general partner is not elected by our unitholders and will not be subject to election or re‑election by our unitholders in the future. Landmark indirectly owns all of the membership interests in our general partner. Our general partner has a board of directors, and our unitholders are not entitled to elect the directors or directly or indirectly to participate in our management or operations. Our general partner will be liable, as general partner, for all of our debts (to the extent not paid from our assets), except for indebtedness or other obligations that are made specifically nonrecourse to it. Whenever possible, we intend to incur indebtedness that is nonrecourse to our general partner.

Our general partner has seven directors, three of whom are independent as defined under the independence standards established by NASDAQ and the Exchange Act. NASDAQ does not require a listed publicly traded limited partnership, such as ours, to have a majority of independent directors on the board of directors of our general partner or to establish a compensation committee or a nominating and corporate governance committee. We are, however, required to have an audit committee of at least three members, and all its members are required to meet the independence and experience standards established by NASDAQ and the Exchange Act.

The executive officers of our general partner allocate their time between managing our business and affairs and the business and affairs of Landmark. The amount of time that our executive officers will devote to our business and the business of Landmark will vary in any given period based on a variety of factors. We expect that our general partner’s executive officers will devote as much time as is necessary for the proper conduct of our business and affairs.

Neither we nor our subsidiaries have any employees. Our general partner has the sole responsibility for providing the personnel necessary to conduct our operations. All of the employees and other personnel that conduct our business are employed or contracted by our general partner and its affiliates, including Landmark, but we sometimes refer to these individuals in this Annual Report on Form 10-K as our employees because they provide services directly to us.

Committees of the Board of Directors

The board of directors of our general partner has established an audit committee and a conflicts committee, and may have such other committees as the board of directors shall determine from time to time. Each of the standing committees of the board of directors has the composition and responsibilities described below.

Audit Committee

We are required to have an audit committee of at least three members, and all its members are required to meet the independence and experience standards established by NASDAQ and Rule 10A‑3 promulgated under the Exchange Act. Thomas Carey White III, Gerald A. Tywoniuk and Keith Benson serve as members of our audit committee. Mr. White serves as the chair of our audit committee. The board of directors of our general partner has determined that Mr. White is an “audit committee financial expert” as defined in Item 407(d)(5) of SEC Regulation S-K. Our audit committee assists the board of directors in its oversight of the integrity of our financial statements and our compliance with legal and regulatory requirements and partnership policies and controls. Our audit committee has the sole authority to retain and terminate our independent registered public accounting firm, approve all auditing services and related fees and the terms thereof, and pre‑approve any non‑audit services to be rendered by our independent registered public accounting firm. Our audit committee is responsible for confirming the independence and objectivity of our independent registered public accounting firm. Our independent registered public accounting firm has unrestricted access to our audit committee.

Conflicts Committee

At least two independent members of the board of directors of our general partner will serve on a conflicts committee to review specific matters that the board believes may involve conflicts of interest and determines to submit to the conflicts committee for review. The conflicts committee will determine if the resolution of the conflict of interest is adverse to the interest of the partnership. The members of the conflicts committee may not be officers or employees of our general partner or directors, officers or employees of its affiliates, including Landmark, and must meet the independence standards established by NASDAQ and the Exchange Act to serve on an audit committee of a board of directors along with other requirements in our partnership agreement. Any matters approved by the conflicts committee will be conclusively deemed to be approved by us and all of our partners and not a breach by our general partner of any duties it may owe us or our unitholders.

84

certified public accountant (inactive) in the state of California. We believe that Mr. White’s expertise in accounting and financial matters, along with his extensive management experience, qualifies him for service as a Director of our general partner.

Gerald A. Tywoniuk was appointed a Director of our general partner in January 2015. Mr. Tywoniuk serves on the Board of Managers of TF-CO Asset Management LLC, and provides consulting services.

We believe that Mr. Tywoniuk’s expertise in accounting and financial matters, along with his extensive management experience, qualifies him for service as a Director of our general partner.

Board Leadership Structure

Directors of the board of directors of our general partner are designated or elected by Landmark. Accordingly, unlike holders of common stock in a corporation, our unitholders will have only limited voting rights on matters affecting our business or governance, subject in all cases to any specific unitholder rights contained in our partnership agreement. The board of directors of our general partner has no policy with respect to the separation of the offices of chairman of the board of directors and chief executive officer. Instead, that relationship is defined and governed by the amended and restated limited liability company agreement of our general partner, which permits the same person to hold both offices.

Board Role in Risk Oversight

Our governance guidelines provide that the board of directors of our general partner is responsible for reviewing our process for assessing the major risks facing us and our options for mitigation. This responsibility will be largely satisfied by our audit committee, which is responsible for reviewing and discussing with management and our registered public accounting firm our major risk exposures and the policies management has implemented to monitor such risk exposures, including our financial risk exposure and risk management policies.

Beneficial Ownership Reporting Compliance

Section 16(a) of the Exchange Act requires the directors and executive officers of our general partner and persons who own more than 10 percent of a registered class of our equity securities, to file reports of beneficial ownership on Form 3 and changes in beneficial ownership on Forms 4 or 5 with the SEC. Based on our review of the reporting forms and written representations provided to us from the persons required to file reports, we believe that each of the directors and executive officers of our general partner and persons who own more than 10 percent of a registered class of our equity securities has complied with the Section 16 reporting requirements for transactions in our securities during the fiscal year ended December 31, 2020.

Code of Business Conduct and Ethics

We adopted a code of business conduct and ethics that seeks to identify and mitigate conflicts of interest between our interests and the interests of our general partner and its employees, directors and officers. However, we cannot assure you that these policies or provisions will always be successful in eliminating or minimizing the influence of such conflicts, and if they are not successful, decisions could be made that might fail to reflect fully the interests of unitholders.

Principal Executive Offices and Internet Address

Our principal executive offices are located at 400 Continental Blvd., Suite 500, El Segundo, CA 90245, and our telephone number is (310) 598‑3173. We post governance documents on our website at http://www.landmarkmlp.com. We expect to make our periodic reports and other information filed with or furnished to the SEC available, free of charge, through our website, as soon as reasonably practicable after those reports and other information are electronically filed with or furnished to the SEC. Information on our website or any other website is not incorporated by reference into this Annual Report Form 10-K and does not constitute a part of this Annual Report Form 10-K.

ITEM 11. Executive Compensation

We do not employ any of the persons responsible for managing our business. Our general partner, under the direction of its board of directors is responsible for managing our operations and for obtaining the services of the employees that operate our business. Our general partner’s executive officers are employed and compensated by Landmark and have responsibilities to both us and Landmark. Our general partner’s executive officers currently devote less than a majority of their working time to matters relating to us and we currently expect our general partner’s executive officers to continue for the foreseeable future to devote less than a majority of their working time to matters relating to us. We currently do not have a compensation committee, and we do not plan to have one. Pursuant to our omnibus agreement we reimburse Landmark for expenses related to certain general and administrative services Landmark provides to us in support of our business, including certain executive management services by certain officers of our general partner and compensation expense for all employees required to manage and operate our business, subject to a quarterly cap equal to 3% of our revenue during the current calendar quarter. This cap on expenses will last until the earlier to occur of: (i) the date on which our revenue for the immediately preceding four consecutive fiscal quarters exceeds $120 million and (ii) November 19, 2021. The full amount of general and administrative expenses incurred is reflected on our income statements, and to the extent such general and administrative expenses exceed the cap amount, the amount of such excess is reflected on our financial statements as a capital contribution from Landmark rather than as a reduction of our general and administrative expenses, except for expenses that would otherwise be allocated to us, which are not included in the amount of general and administrative expenses.

Except with respect to any equity incentive awards in us that may be granted under our 2014 Long‑Term Incentive Plan, or “LTIP,” our general partner’s executive officers do not receive any separate amounts of compensation for their services to us and all compensation decisions for our general partner’s executive officers are made by Landmark, without input from our general partner’s board of directors or any committees thereof. Any awards granted to our general’s partner’s executive officers under our LTIP are determined and granted by our general partner’s board of directors or one of its applicable committees. No equity incentive awards were granted to any of our executive officers in 2020.

Compensation of our Directors

In connection with the IPO, the board of directors of the General Partner adopted the Landmark Infrastructure Partners GP LLC Non-Employee Director Compensation Plan (the “Non-Employee Director Compensation Plan”). On January 25, 2018, the board of directors of the General Partner adopted the Amended and Restated Non-Employee Director Compensation Plan. The Amended and Restated Non-Employee Director Compensation Plan provides each director that is neither an officer of the General Partner nor an employee or an affiliate of the General Partner with annualized compensation consisting of $40,000 in cash, payable quarterly, an annual grant of Common Units valued at $40,000 and additional cash compensation for attending meetings of the board of directors of the General Partner or a committee thereof. Pursuant to the Amended and Restated Non-Employee Director Compensation Plan, the chairman of the audit committee of the board of directors shall be entitled to additional annualized cash compensation of $15,000 and the chairman of any other committee of the board of directors, as may be established at any time, shall be entitled to an amount in cash as determined by the board of directors. Such directors will also receive reimbursement for out‑of‑pocket expenses associated with attending board or committee meetings and director and officer liability insurance coverage. Officers, employees or paid consultants or advisors of us or our general partner or Landmark or its affiliates who also serve as directors will not receive additional compensation for their service as directors. All directors will be indemnified by us for actions associated with being a director to the fullest extent permitted under Delaware law.

The following table sets forth the total compensation paid to our non-employee directors as compensation for their year of service to us in 2020.

ITEM 13. Certain Relationships and Related Transactions, and Director Independence

As of December 31, 2020, Landmark and affiliates own 3,415,405 common units, representing a 13.4% limited partner interest in us. In addition, our general partner owns a non‑economic general partner interest in us.

Distributions and Payments to Our General Partner and Its Affiliates

The following table summarizes the distributions and payments made by us to our general partner and its affiliates in connection with our ongoing operation and liquidation. These distributions and payments were and will be determined by and among affiliated entities and, consequently, are not the result of arm’s‑length negotiations.

Operational stage

Distributions of available cash to our general partner and its affiliates	We will generally make cash distributions to the unitholders pro rata, including Landmark and affiliates, as holder of an aggregate of 3,415,405 common units as of December 31, 2020. In addition, if distributions exceed the minimum quarterly distribution and target distribution levels, the incentive distribution rights held by our general partner will entitle our general partner to increasing percentages of the distributions, up to 50% of the distributions above the highest target distribution level.
Payments to our general partner and its affiliates	Under our partnership agreement, we are required to reimburse our general partner and its affiliates for all costs and expenses that they incur on our behalf for managing and controlling our business and operations. Except to the extent specified under our omnibus agreement, our general partner determines the amount of these expenses and such determinations must be made in good faith under the terms of our partnership agreement. Under the omnibus agreement, we agreed to reimburse Landmark for expenses related to certain general and administrative services Landmark will provide to us in support of our business, subject to a quarterly cap equal to 3% of our revenue during the current calendar quarter. To the extent our general and administrative expenses exceed this cap Landmark will reimburse the partnership for the excess over the cap. This cap on expenses will last until the earlier to occur of: (i) the date on which our revenue for the immediately preceding four consecutive fiscal quarters exceeded $120 million and (ii) November 19, 2021. The expenses of other employees will be allocated to us based on the amount of time actually spent by those employees on our business. These reimbursable expenses also include an allocable portion of the compensation and benefits of employees and executive officers of other affiliates of our general partner who provide services to us. We will also reimburse Landmark for any additional out‑of‑pocket costs and expenses incurred by Landmark and its affiliates in providing general and administrative services to us. Please read “– Agreements Governing the Transactions – Omnibus Agreement” below and Item 11., “Executive Compensation – Compensation of Our Directors.” In connection with third party acquisitions, Landmark will be obligated to provide certain acquisition services to us. We will pay Landmark reasonable fees, as mutually agreed to by Landmark and us, for providing any such acquisition services we choose to utilize. These acquisition services fees will not be subject to the cap on general and administrative expenses. However, we are under no obligation to utilize Landmark for acquisition services, and may utilize the services of third parties in connection with acquisitions.
Withdrawal or removal of our general partner	If our general partner withdraws or is removed, its general partner interest and its incentive distribution rights will either be sold to the new general partner for cash or converted into common units, in each case for an amount equal to the fair market value of those interests.

88

Liquidation stage

Liquidation Upon our liquidation, the partners, including our general partner, will be entitled to receive liquidating distributions according to their respective capital account balances.

Our Agreements with Landmark

Omnibus Agreement

We entered into an omnibus agreement with Landmark and our general partner for the purposes of:

• reimbursement for all costs and expenses incurred by Landmark in providing us partnership, general and administrative services (which reimbursement is in addition to certain expenses of our general partner and its affiliates that are reimbursed under our partnership agreement);

• an indemnity by Landmark for certain liabilities associated with our assets; and

So long as Landmark controls our general partner, the omnibus agreement will remain in full force and effect. If Landmark ceases to control our general partner, either party may terminate the omnibus agreement, provided that the indemnification obligations will remain in full force and effect in accordance with their terms.

We will reimburse Landmark quarterly for the expenses incurred by Landmark and its affiliates in providing these services. Landmark has agreed that our obligation to reimburse Landmark for certain of these general and administrative services during any calendar quarter will be capped at 3% of our revenue during the current calendar quarter. The full amount of general and administrative expenses incurred will be reflected on our income statements, and to the extent such general and administrative expenses exceed the cap amount, the amount of such excess will be reimbursed by Landmark which will be reflected in our financial statements as a capital contribution from Landmark rather than as a reduction of our general and administrative expenses, except for expenses that would otherwise be allocated to us, which are not included in the amount of general and administrative expenses.

Acquisition Services

In connection with third party acquisitions, Landmark will be obligated to provide acquisition services to us, including asset identification, underwriting and due diligence, negotiation, documentation and closing, at the reasonable request of our general partner, but we are under no obligation to utilize such services. We will pay Landmark reasonable fees, as mutually agreed to by Landmark and us, for providing these services. These fees will not be subject to the cap on general and administrative expenses described above.

Indemnification

Indemnification by Us.  We have agreed to indemnify Landmark for events and conditions associated with the ownership or operation of our assets that occur after the closing of the IPO (other than any environmental liabilities for which Landmark is specifically required to indemnify us as described above). There is no limit on the amount for which we will indemnify Landmark under the omnibus agreement.

License of Trademarks.  Landmark granted us a nontransferable, nonexclusive, royalty‑free worldwide right and license to use certain trademarks and trade names owned by Landmark.

Other Agreements with Landmark and Related Parties

Patent License Agreement

We entered into a Patent License Agreement (the “License Agreement”) with American Infrastructure Funds, LLC (“AIF”), an affiliate of the controlling member of Landmark. Under the License Agreement, AIF granted us a nonexclusive, perpetual license to practice certain patented methods related to the apparatus and method for combining easements under a master limited partnership. We have agreed to pay AIF a license fee of $50,000 for the second year of the License Agreement, and thereafter, an amount equal to the greater of (i) one‑tenth of one percent (0.1%) of our gross revenue received during such contract year; or (ii) $100,000. For each of the years ended December 31, 2020, 2019 and 2018, we incurred $0.1 million of license fees related to the AIF patent license agreement, respectively.

89

Procedures for Review, Approval and Ratification of Related Person Transactions

The board of directors of our general partner adopted a related party transactions policy that provides that the board of directors of our general partner or its authorized committee will review on at least a quarterly basis all related person transactions that are required to be disclosed under SEC rules and, when appropriate, initially authorize or ratify all such transactions. In the event that the board of directors of our general partner or its authorized committee considers ratification of a related person transaction and determines not to so ratify, the code of business conduct and ethics will provide that our management will make all reasonable efforts to cancel or annul the transaction.

The related party transactions policy provides that, in determining whether or not to recommend the initial approval or ratification of a related person transaction, the board of directors of our general partner or its authorized committee should consider all of the relevant facts and circumstances available, including (if applicable) but not limited to: (1) whether there is an appropriate business justification for the transaction; (2) the benefits that accrue to us as a result of the transaction; (3) the terms available to unrelated third parties entering into similar transactions; (4) the impact of the transaction on a director’s independence (in the event the related person is a director, an immediate family member of a director or an entity in which a director or an immediate family member of a director is a partner, shareholder, member or executive officer); (5) the availability of other sources for comparable products or services; (6) whether it is a single transaction or a series of ongoing, related transactions; and (7) whether entering into the transaction would be consistent with the code of business conduct and ethics.

ITEM 14. Principal Accountant Fees and Services

Audit Fees

Category	2020		2019
Audit fees(1)	$	901	$	1,140

(2) Audit-related fees represent fees for professional services primarily provided in connection with agreed-upon procedures related to the Partnership’s subsidiaries’ securitization transactions.

Under the policy, the audit committee, or the chair of the audit committee, must pre-approve any audit and non-audit service provided to us by Ernst & Young LLP, unless the engagement is entered into pursuant to appropriate preapproval policies established by the audit committee or if such service falls within available exceptions under SEC rules.

Auditor Independence

The audit committee of the board of directors of our general partner has considered whether Ernst & Young LLP is independent for purposes of providing external audit services to us, and the audit committee has determined that Ernst & Young LLP is independent.

Report of Independent Registered Public Accounting Firm

To the Board of Directors of Landmark Infrastructure Partners GP LLC and Partners of Landmark Infrastructure Partners LP

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Landmark Infrastructure Partners LP (the “Partnership”) as of December 31, 2020 and 2019, the related consolidated statements of operations, comprehensive income, equity and mezzanine equity, and cash flows for each of the three years in the period ended December 31, 2020 and the related notes and financial statement schedule listed in the Index at Item 15(a) (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the consolidated financial position of the Partnership at December 31, 2020 and 2019, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2020, in conformity with U.S. generally accepted accounting principles.

Adoption of New Accounting Standards

As discussed in Note 2 to the consolidated financial statements, the Partnership changed its method of accounting for leases in the year ended December 31, 2019 due to the adoption of ASU 2016-02, Leases.

Basis for Opinion

These financial statements are the responsibility of the Partnership's management. Our responsibility is to express an opinion on the Partnership’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Partnership in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Partnership is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Partnership's internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of the critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

	Purchase price accounting for digital infrastructure acquisitions
Description of the Matter	As more fully disclosed in Notes 3 and 4 to the consolidated financial statements, the Partnership purchased digital infrastructure properties for a total purchase price of $142.8 million. These transactions were accounted for as asset acquisitions, with the cost to purchase the assets allocated based on the relative fair values of the assets acquired and liability assumed. Auditing the Partnership’s allocation of cost to its asset acquisitions was complex due to the significant estimation required by management in determining the fair value of the assets purchased and liability assumed. The significant estimation was primarily due to the judgmental nature of the inputs to the valuation models used to measure fair value as well as the sensitivity of the respective fair values to the significant underlying assumptions. The Partnership utilized the sales comparison approach to measure the fair value of the land assets, the cost approach to measure the fair value of the building and site improvements, and the income approach to measure the fair value of the real property interest and liability assumed. Comparable land sales are utilized in the sales comparison approach. Estimates of replacement costs are used in the cost approach. The income approach utilizes market assumptions including discount rates, market rental rates, capitalization rates, estimates of future cash flows and market interest rates. These significant assumptions are forward-looking and could be affected by future economic and market conditions.
How We Addressed the Matter in Our Audit	For the Partnership’s asset acquisitions, we performed audit procedures that included, among others, reading the respective transaction agreements, and testing the completeness and accuracy of the underlying data used in the estimates of fair value. We involved our valuation specialists to assist in evaluating the methodologies utilized by the Partnership in developing the fair value estimates as well as assessing the significant assumptions mentioned above. For example, with the assistance of our valuation specialists, we performed independent calculations to evaluate the appropriateness of management’s selected comparable land sales and cost estimates, and obtained market specific information (i.e. discount rates, market rental rates, capitalization rates and market interest rates) and compared it to the information utilized by the Partnership.

/s/ Ernst & Young LLP

We have served as the Partnership's auditor since 2012.

Landmark Infrastructure Partners LP

Notes to Consolidated Financial Statements

1. Organization

Landmark Infrastructure Partners LP (the “Partnership”) was formed on July 28, 2014 by Landmark Dividend LLC (“Landmark” or “Sponsor”) to acquire, develop, own and manage a portfolio of real property interest and infrastructure assets that are leased to companies in the wireless communication, digital infrastructure, outdoor advertising and renewable power generation industries. The Partnership is a master limited partnership organized in the State of Delaware and has been publicly traded since its initial public offering on November 19, 2014 (the “IPO”). On July 31, 2017, the Partnership completed changes to its organizational structure by transferring substantially all of its assets to a consolidated subsidiary, Landmark Infrastructure Inc., a Delaware corporation (“REIT Subsidiary”), which elected to be taxed as a REIT commencing with its taxable year ending December 31, 2017. References in this report to “Landmark Infrastructure Partners LP,” the “partnership,” “we,” “our,” “us,” or like terms, refer to Landmark Infrastructure Partners LP.

Our operations are managed by the board of directors and executive officers of Landmark Infrastructure Partners GP LLC, our general partner (the “General Partner”). As of December 31, 2020, our Sponsor and affiliates own (a) our general partner; (b) 3,415,405 common units representing limited partnership interest in the Partnership (“Common Units”) and; (c) all of the incentive distribution rights (“IDRs”).

2. Basis of Presentation and Summary of Significant Accounting Policies

Basis of Presentation and Principles of Consolidated Financial Statements

During the year ended December 31, 2018, the Partnership completed one drop-down acquisition of 127 tenant sites and related real property interests from the Sponsor and affiliates in exchange for total consideration of $59.9 million (the “Drop-down Acquisitions” or “Drop-down Assets”). There were no Drop-down Acquisitions during the years ended December 31, 2020 and 2019. Drop-down Acquisitions from the Sponsor and affiliates are accounted for prospectively as transfers of net assets in the period in which the transfer occurs at the net carrying value. Any differences between the cash consideration and the net carrying value of the transfer of net assets is allocated to the General Partner.  

On an ongoing basis, we evaluate each legal entity that is not wholly owned by us in accordance with the consolidation guidance. The accompanying consolidated financial statements include the accounts of the Partnership, its wholly-owned subsidiaries and those entities in which it has a controlling interest. Investments in entities that the Partnership does not control are accounted for using the equity or cost method, depending upon the Partnership’s ability to exercise significant influence over operating and financial policies.

The consolidated financial statements were prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). All intercompany transactions and account balances have been eliminated. Management believes that the assumptions and estimates used in the preparation of the underlying consolidated financial statements are reasonable. However, the consolidated financial statements herein do not necessarily reflect what the Partnership’s financial position, results of operations, comprehensive income or cash flows would have been if the Partnership had been a stand-alone entity during the periods presented. As a result, historical financial information is not necessarily indicative of the Partnership’s future results of operations, comprehensive income, financial position or cash flows. All references to tenant sites are unaudited.

Use of Estimates

The preparation of the consolidated financial statements, in conformity with GAAP, requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.

Purchase Accounting for Acquisitions

The Partnership applies the asset acquisition method to all acquired investments of real property interests for transactions that meet the definition of an asset acquisition based on the revised framework for determining whether an integrated set of assets meets the definition of a business. The purchase consideration for the real property interests is allocated to the acquired tangible assets, such as land and building, and the identified intangible assets and liabilities, consisting of the value of perpetual and limited life easements, above-market and below-market leases and in-place leases, based in each case on their fair values. The fair value of the assets acquired and liabilities assumed is typically determined by using the discounted cash flow valuation method using discount rates ranging between 6% and 20% with a weighted average discount rate of 8.5%. In certain instances, such as data center acquisitions, the sales comparison approach is used to determine the fair value of the land assets, the cost approach to determine the fair value of the building and site improvements, and the income approach to determine the fair value of the real property interest and liability assumed. When determining the fair value of intangible assets acquired, the Partnership estimates the applicable discount rate and the timing and amount of future cash flows. Transaction costs related to asset acquisitions are capitalized.

F-9

Factors considered in estimating the fair value of tangible and intangible assets acquired include information obtained about each asset as a result of Landmark’s pre-acquisition due diligence and its marketing and leasing activities. In order to calculate the estimated in-place lease value, we employed the income approach in accordance with ASC 805 by multiplying the anticipated market absorption period by the market rent at the time of acquisition for each in-place lease agreement. Based on our experience in the industry, we have determined a range of lease execution timelines to be between one and twelve months. For the in-place lease valuation, we consider a lease-up period of four to eight months to be representative of the market.

We estimated the fair value of real property interests using the income approach. The discount rates used ranged from 6% to 20% with a weighted average discount rate of 8.5%. In certain instances, such as data center acquisitions, the sales comparison approach is used to determine the fair value of the land assets, the cost approach to determine the fair value of the building and site improvements, and the income approach to determine the fair value of the real property interest and liability assumed. The value of tenant relationships has not been separated from in-place tenant lease value for the real estate acquired as such value and its consequence to amortization expense is materially consistent with the in-place tenant lease value for these particular acquisitions. Should future acquisitions of real property interests result in allocating material amounts to the value of tenant relationships, an amount would be separately allocated and amortized over the estimated life of the relationship. The value of in-place leases and customer relationship is amortized to expense over the estimated period the tenant is expected to be leasing the site under the existing terms which typically range from 2 to 20 years. If a tenant lease were to be terminated prior to its stated expiration, all unamortized amounts relating to that lease would be impaired.

The discount rate associated with each asset varies based on the location of an asset (including demographics and zoning restrictions), and other asset specific characteristics. Market rent for each asset is determined based on location of each asset, asset type, zoning restrictions, ground space necessary for the tenant’s equipment, remaining site capacity, visibility (specifically for billboards), and nearby sites.

In allocating the purchase consideration of the identified intangible assets and liabilities of an acquired asset, above-market, below-market and in-place lease values are calculated based on the present value (using a discount rate that reflects the risks associated with the leases acquired) of the difference between (i) the contractual amounts to be paid pursuant to the in-place leases and (ii) management’s estimate of fair market lease rates for the corresponding in-place leases measured over the estimated period the tenant is expected to be leasing the site under the above or below-market terms. The capitalized above-market and below-market lease values are amortized as a decrease or increase, respectively, to rental income over the estimated period the tenant is expected to be leasing the site. Wireless communication and outdoor advertising tenant leases obtained by the Partnership through its acquisition of real property interests are generally cancellable, upon 30 to 180 days’ notice by the tenants, with no significant penalty. Digital infrastructure and renewable power generation tenant leases are generally non-cancellable. With respect to below-market leases, consideration is given to any below-market renewal periods. However, for wireless communication assets, we estimated the above/below-market lease value over an analysis period of the earlier of the lease expiration or 10 years based on estimated useful life of the underlying equipment and assets. For outdoor advertising assets, we estimated the above- or below-market lease value over an analysis period of the earlier of the lease expiration or 20 years, based on a longer estimated useful life of 20 years for billboards.

Real Property Interests and Depreciation and Amortization

Real property interests consist primarily of land, easements and lease assignments underlying wireless communication, digital infrastructure, outdoor advertising and renewable power generation. The real property interests are typically held as ownership of land or easements to use land, or roof tops, both of which allow us to use the asset for a specific purpose. Real property interests, excluding land, are intangibles that are recorded at cost. Amortization is computed using the straight-line method over the estimated useful lives of the real property interests, which is estimated as the shorter of the revenue generating period of the asset or the term of the real estate rights which range from 12 to 99 years. Depreciation of buildings, site improvements or equipment is computed using the straight-line method over the assets’ estimated useful lives. Real property interests with a perpetual term are not amortized but evaluated periodically for impairment.

The Partnership assesses whether there has been an impairment in the value of long-lived assets whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount to the future estimated net cash flows, undiscounted and without interest, expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the estimated fair value of the assets based upon what a market participant would be willing to pay for the real estate interest. The estimated fair value of the asset group identified for step two testing is based on either Level 3 inputs utilizing the income approach with a market discount rate and estimated cash flows, or Level 2 inputs based upon the sales comparison approach to a similar asset. Assets to be disposed of are reported at the lower of the carrying amount or fair value, less costs to sell utilizing the Level 3 and Level 2 inputs discussed below.

F-10

Concurrent with the Partnership’s adoption of ASU No. 2016-02 on January 1, 2019, the Partnership has elected to recognize expense associated with short-term leases (those with a non-cancellable lease term of 12 months or less) under which the Partnership is the lessee on a straight-line basis and not recognize those leases on its consolidated balance sheets. For leases other than short-term operating and finance leases under which the Partnership is the lessee, such as ground leases, the Partnership recognizes a right-of-use asset and related lease liability on its consolidated balance sheet at inception of the lease based on the present value of the remaining minimum rental payments using each respective lease term and a corresponding incremental borrowing rate. Operating lease assets are included in right of use, net and finance lease assets are included in real property interests in the consolidated balance sheets.

Development Operations

The Partnership capitalizes direct construction and development costs, including pre-development costs, interest, and other costs directly related and essential to the development or construction of an asset. The Partnership capitalizes construction and development costs while substantive activities are ongoing to prepare an asset for its intended use. Fluctuations in our development, pre-construction, and construction activities could result in significant changes to expenses and net income. Costs incurred after a project is substantially complete and ready for its intended use are expensed as incurred. Should development, pre-construction, or construction activity cease, interest and certain other costs would no longer be eligible for capitalization and would be expensed as incurred. Expenditures for repairs and maintenance are expensed as incurred. The Partnership computes depreciation on assets placed in service and improvements using the straight-line method over the assets’ estimated useful lives.

Development projects and other similar contracts are assessed to determine whether it continues to meet our investment return standards. Assessments are made separately for each project on a quarterly basis and are affected by the following factors relative to the market in which the asset is located, among others: estimated development and construction costs and projected profitability. When a decision is made to cease construction on certain projects due to market conditions and/or fluctuations in our development strategy, we write off the related capitalized costs, including pre-construction costs. During the year ended December 31, 2019, the Partnership ceased construction on a certain development project and recognized impairment charges of $1.6 million including a write off of $0.1 million in capitalized interest.

Fair Value of Financial Instruments

The standard establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable input be used when available. Observable inputs are inputs that the market participants would use in pricing an asset or liability developed based on market data obtained from sources independent of the Partnership. Unobservable inputs are inputs that reflect the Partnership’s assumptions about what market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. The hierarchy is measured in three levels based on the reliability of inputs:

Level 1 – unadjusted quoted prices in active markets that are accessible at the measurement date for identical assets or liabilities.

Level 2 – quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-derived valuations in which significant inputs and significant value drivers are observable in active markets; and,

Level 3 – prices or valuations derived from other valuation methodologies where little or no market data is available that requires inputs that are both significant to the fair value measurement and unobservable, including pricing models, discounted cash flow models and similar techniques.

Cash and Cash Equivalents

All highly liquid investments with a maturity of three months or less when purchased are considered to be cash and cash equivalents. The Partnership monitors the cash balances in its operating accounts and adjusts the cash balances as appropriate; however, these cash balances could be impacted if the underlying financial institutions fail or are subject to other adverse conditions in the financial markets. To date, the Partnership has experienced no loss or lack of access to cash in the operating accounts.

Restricted Cash

Restricted cash primarily consists of amounts pledged as collateral to secure obligations. As of December 31, 2020 and 2019, the amount of restricted cash was $3.2 million and $5.6 million. See Note 10, Debt for additional information.

Accounting for Derivative Financial Instruments and Hedging Activities

The Partnership utilizes interest rate swap contracts to manage interest costs and risks associated with changing interest rates. These derivative financial instruments are carried at fair value on the consolidated balance sheets, with the change in such fair value being recorded through earnings as an unrealized gain or loss in the consolidated statements of operations.

F-11

Investments in Receivables, Net

The Partnership acquired streams of future cash flows associated with real property interests and certain lease arrangements that meet the definition of a financial asset within the wireless communication, outdoor advertising and renewable power generation industries. For certain investments in receivables, the Partnership has no significant rights or obligations associated with the cash flows other than in certain arrangements, to pass a portion of the cash flows received to the owner of the respective lease. Additionally, certain lease arrangements of real property interests meet the definition of a financial asset and are included in investments in receivables in our financial statements. The future cash flow streams are recorded at their net present value based on the estimated net cash flows to be received by the Partnership using the implied discount rate at the date of the acquisition.

Receivables are classified as held-for-investment based on management’s intent and ability to hold the receivables for the foreseeable future or to maturity. Receivables held-for-investment are carried at amortized cost and are reduced by a valuation allowance for estimated credit losses as necessary. Interest on receivables is accreted to income over the life of the receivables using the interest method. The interest method is applied on an individual receivable basis when collectability of the future payments, when due in accordance with the contractual terms of the arrangement, is reasonably assured. Receivables are transferred from held-for-investment to held-for-sale when management no longer intends to hold the receivables for the foreseeable future. Receivables held-for-sale are recorded at the lower of cost or fair value.

As of January 1, 2020, the Partnership revised its measurement of impairment for investment in receivables measured at amortized cost from an incurred loss methodology to an expected loss methodology, in accordance with the adoption of ASU No. 2018-19, Codification Improvements to Topic 326, Financial Instruments – Credit Losses. The measurement of expected credit losses under the current expected credit loss model is based on relevant information including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amounts. As a result, the Partnership recognized $0.1 million as a cumulative adjustment to retained earnings and as a reduction to investment in receivables.

Prior to January 1, 2020, receivables were placed on non-accrual status when management determined that the collectability of contractual amounts were not reasonably assured. While on non-accrual status, receivables were either accounted for on a cash basis, in which income is recognized only upon receipt of cash, or on a cost-recovery basis, where cash receipts reduced the carrying value of the receivable, based on management’s expectation of future collectability. Allowances were established for receivables based upon an estimate of probable losses on an individual receivable by receivable basis if they were determined to be impaired. Receivables were impaired when it was deemed probable that the Partnership would be unable to collect all amounts when due in accordance with the contractual terms of the loan. An allowance is based upon the Partnership’s assessment of the borrower’s overall financial condition, economic resources, payment record, the prospects for support from any financially responsible guarantors and, if appropriate, the net realizable value of any collateral. These estimates consider all available evidence including the expected future cash flows discounted at the receivable’s effective interest rate, fair value of collateral, general economic conditions and trends, historical and industry loss experience and other relevant factors, as appropriate.

In 2018 and 2019, the Partnership assessed investments in receivables for impairment. Internally generated cash flow projections were used to determine if the receivables were expected to be repaid in accordance with the terms of the related agreements. If it was probable that a receivable would not be repaid in accordance with the related agreement, the receivable was deemed impaired. To measure impairment, the present value of the expected future cash flows discounted was calculated using the original effective interest rate. If the present value was less than the carrying value of the receivable, a specific impairment reserve is recorded for the difference. For the year ended December 31, 2018, the Partnership impaired 16 of its investments in receivables and recognized impairment charges totaling $0.8 million. The investments in receivables were impaired to their net realizable value. There was no impairment of investments in receivables during the year ended December 31, 2019.

Investment in Unconsolidated Joint Venture

The Partnership accounts for its investment in an unconsolidated joint venture using the equity method of accounting. Under the equity method, the investment is initially recorded at fair value and subsequently adjusted for distributions and the Partnership’s proportionate share of equity in the joint venture’s income (loss). The Partnership recognizes its proportionate share of the ongoing income or loss of the unconsolidated joint venture as equity income (loss) from unconsolidated joint venture on the consolidated statements of operations. On a quarterly basis, the Partnership evaluates its investment in an unconsolidated joint venture for other-than-temporary impairments. The Partnership elected as an accounting policy to reflect unconsolidated joint venture distributions in the consolidated statements of cash flows using the nature of the distribution approach. Accordingly, the net proceeds were classified as return on investment in unconsolidated joint venture within the operating activities section of the consolidated statements of cash flows for the year ended December 31, 2020 and 2019.

Discontinued Operations

If the disposition of a component, being an operating or reportable segment, business unit, subsidiary or asset group, represents a strategic shift that has or will have a major effect on the Partnership’s operations and financial results, the operating profits or losses of the component disposed of by sale or when classified as held for sale, and the gain or loss upon disposition of the component, are presented as discontinued operations in the statements of operations.

On June 17, 2020, the Partnership completed the sale of its interest in the consolidated joint venture that holds its European outdoor advertising portfolio for a purchase price of £95 million. As a result, the sale of the European outdoor advertising portfolio represents a strategic shift that will have a major effect on the Partnership’s operations and financial results and has met the criteria as discontinued operations in June 2020. Accordingly, for all prior periods presented, the related assets and liabilities, including borrowings under the revolving credit facility and an interest rate swap agreement denominated in British pound sterling (“GBP”), are presented as assets and liabilities held for sale on the consolidated balance sheets (Note 4) and the related operating results, including interest expense and unrealized loss on the interest rate swap agreement denominated in GBP, are presented as income from discontinued operations on the consolidated statement of operations (Note 9).

Deferred Loan Costs

Costs incurred associated with the revolving credit facility are capitalized as deferred loan costs and are included in deferred loan costs, net in the consolidated balance sheets in accordance with ASU 2015-15, Interest – Imputation of Interest (Subtopic 835-30): Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements. Costs incurred in obtaining the secured debt facilities are deducted from the carrying amount of the debt liabilities and deferred loan costs are amortized to interest expense over the life of the related loan. When facilities are amended and restated that result in an of extinguishment of debt, any unamortized deferred loan costs, as well as charges incurred for the termination, are recorded to interest expense in the period of the amendment and restatement.

Revenue Recognition

The Partnership recognizes rental income under operating leases, including rental abatements, lease incentives and contractual fixed increases, if any, from tenants under lease arrangements with minimum fixed and determinable increases on a straight-line basis over the non-cancellable term of the related leases when collectability is reasonably assured. The excess of rents recognized over amounts contractually due pursuant to the underlying leases are recorded as deferred rent assets. The excess of rent payments collected over amounts recognized contractually due pursuant to the underlying lease are recorded as prepaid rents. The Partnership accounts for and presents tenant reimbursements as a component of rental revenue in our consolidated income statements in accordance with the new lease standard (“ASC 842”). Tenant reimbursements are recognized as revenue in the period during which the applicable expenses are incurred and the tenant’s obligation to reimburse us arises.

For the years ended December 31, 2020, 2019, and 2018, leases obtained by the Partnership through its acquisition and ownership of real property interests in the wireless communication industry and the outdoor advertising industry were generally cancelable upon 30 - 180 days’ notice by the tenants with no significant penalty. The Partnership evaluates whether the lease arrangements economically compel the tenant to not cancel the lease in determining the term of the lease by considering various factors such as cancellation rights, availability of alternative sites, and historical cancellation rates. For cancellable leases where the tenant is not economically compelled to continue the lease, the term of the lease is considered to be the non-cancellable period with rental abatements and contractual fixed rate increases recorded in the period the amounts become due and payable. Leases obtained through development projects, are generally non‑cancellable for the initial term.

• Wireless Communication – As a result of various factors, including the cancellation rights, ability to find alternative sites, credit risk, and historical cancellation and lease amendment rates, the lease term is generally considered to be the non-cancellable term of the lease of 30 to 180 days. For these leases, rental abatements and contractual fixed increases are recorded in the period the amounts become due and payable.

• Digital Infrastructure – The lease term is generally non-cancellable.

• Outdoor Advertising and Renewable Power Generation – The lease term is generally considered to be the non-cancellable term of the remaining portion of the existing term of the lease.

The capitalized above-market and below-market lease values are amortized as a decrease or increase, respectively, to rental income over the estimated period the tenant is expected to be leasing the site.

Certain leases provide for the greater of a minimum rent or a percentage of the revenue generated by the tenant (“Contingent Rent”). Contingent Rent is recognized when measurable and all possible contingencies have been eliminated. During the years ended December 31, 2020, 2019, and 2018, the Partnership recognized $1.4 million, $1.6 million and $1.2 million of Contingent Rent, respectively.

Rents Receivable, net

Rents receivables consists of tenant receivables arising in the normal course of business. Tenant receivables are uncollateralized customer obligations requiring payment within various time frames not to exceed one year from the invoice date. If the Partnership determines that collectability of lease payments is not probable, the rent receivable balance is written off and recognized as a decrease in revenue in that period and future revenue recognition is limited to amounts contractually owed and paid.

F-13

Income Taxes

The Partnership is generally not subject to federal, state or local income taxes, except for our subsidiary Landmark Infrastructure Asset OpCo LLC (“Asset OpCo”) and our foreign subsidiaries. Each limited partner is responsible for the tax liability, if any, related to its proportionate share of the Partnerships’ taxable income or loss. Asset OpCo conducts certain activities that may not generate qualifying income and will be treated as a corporation for U.S. federal income tax purposes. Asset OpCo and certain consolidated foreign subsidiaries of the Partnership conduct certain activities in international locations that generate taxable income and will be treated as taxable entities. Additionally, our consolidated REIT subsidiary, Landmark Infrastructure Inc., a Delaware corporation, files as a corporation for U.S. federal income tax purposes. The REIT Subsidiary has elected to be treated as a REIT and we believe that it has operated in a manner that has allowed the REIT Subsidiary to qualify as a REIT for federal income tax purposes, and the REIT Subsidiary intends to continue operating in such manner. If the REIT Subsidiary fails to qualify as a REIT in any taxable year, and is unable to avail itself of certain savings provisions, all of its taxable income would be subject to federal income tax at regular corporate rates. The Partnership may also be subject to various non-income taxes, filing fees, and franchise taxes in various states that are reflected in operating expenses. The Partnership follows the requirements of ASC Topic 740, Income Taxes (“ASC 740”), relating to uncertain tax positions. Based on its evaluation under ASC 740, the Partnership has concluded that there are no significant uncertain tax positions requiring recognition in the consolidated financial statements, nor has the Partnership been assessed interest or penalties by any major tax jurisdictions.

Foreign Currency Translation

Assets and liabilities denominated in foreign currencies that are translated into U.S. dollars use exchange rates in effect at the end of the period, and revenues and expenses denominated in foreign currencies that are translated into U.S. dollars use average rates of exchange in effect during the related period. Gains and losses resulting from translation adjustments are included in accumulated other comprehensive income (loss).

Foreign Currency Transactions

Transactions denominated in a currency other than U.S. dollars are recorded upon initial recognition at the exchange rate on the date of the transaction. After initial recognition, monetary assets and liabilities denominated in a foreign currency are remeasured at each reporting date into the functional currency at the exchange rate on that date. For all periods presented, the foreign currency interest rate swap agreement and a debt agreement that resulted in mark to market foreign currency transaction adjustments were reclassified to discontinued operations.  

Risk Management

The Partnership is subject to risks incidental to the ownership and investment in real property interests. These risks and uncertainties include the competitive environment in which the Partnership operates – local, regional, and national economic conditions, including consumer confidence, employment rates, and the availability of capital; uncertainties and fluctuations in capital and securities markets; the cyclical and competitive nature of the real estate industry; changes in tax laws and their interpretation; legal proceedings; effect of restrictive covenants in the loan agreements; and the effects of governmental regulation.

In the normal course of business, the Partnership encounters economic risk, including interest rate risk, currency risk, credit risk, and market risk. Interest rate risk is the result of movements in the underlying variable component of financing rates. Credit risk is the risk of default that results from an underlying tenant/borrower’s inability or unwillingness to make contractually required payments. Market risk reflects changes in the valuation of real property interests and investments in receivables held by the Partnership.

Concentration of Credit Risk

The Partnership’s credit risk relates primarily to rent receivables, investments in receivables, cash and interest rate swap agreements. Cash accounts at each U.S. institution are insured by the Federal Deposit Insurance Corporation up to $250,000. The Partnership has not experienced any losses to date on invested cash.

Credit risk associated with interest rate swap agreements arises from the potential failure of counterparties to perform in accordance with the terms of their contracts. The Partnership’s risk management policies define parameters of acceptable market risk and limit exposure to credit risk. Credit exposure resulting from derivative financial instruments is considered in their fair value amounts, among other factors such as the potential adverse position exposure arising from changes over time in interest rates, maturities, and other relevant factors. The Partnership does not anticipate nonperformance by any of its counterparties.

The Partnership’s real property interests are primarily located throughout the United States. The ability of the tenants to honor the terms of their respective leases is dependent upon the economic, regulatory, and social factors affecting the communities in which the tenants operate. In certain instances, the Partnership’s position in the real property interest may be subordinate to a mortgage lender on the real property.

F-14

Business Segments

The Financial Accounting Standards Board (“FASB”) accounting guidance with regard to disclosures about segments of an enterprise and related information establishes standards for the manner in which public business enterprises report information about operating segments. The Partnership has four reportable segments, wireless communication, digital infrastructure, outdoor advertising and renewable power generation for all periods presented.

Recently Issued Accounting Standards

Changes to GAAP are established by the FASB in the form of Accounting Standards Updates (“ASUs”) to the FASB’s Accounting Standard Codification. The Partnership considers the applicability and impact of all ASUs. Newly issued ASUs not listed below are expected to not have any material impact on its combined financial position and results of operations because either the ASU is not applicable or the impact is expected to be immaterial.

In April 2020, the FASB issued a question and answer document (the “Lease Modification Q&A”) focused on the application of lease accounting guidance to lease concessions provided as a result of the COVID-19 pandemic. Under existing GAAP, the Partnership would have to determine, on a lease by lease basis, if a lease concession was the result of a new arrangement reached with the tenant (treated within the lease modification accounting framework) or if a lease concession was under the enforceable rights and obligations within the existing lease agreement (precluded from applying the lease modification accounting framework). The Lease Modification Q&A allows the Partnership, if certain criteria have been met, to bypass the lease by lease analysis, and instead elect to either apply the lease modification accounting framework or not, with such election applied consistently to leases with similar characteristics and similar circumstances. The Partnership has elected to apply such relief and will avail itself of the election to avoid performing a lease by lease analysis and not apply the lease modification accounting framework. The Lease Modification Q&A had no material impact on the Partnership’s consolidated financial statements.

In June 2016, the FASB issued ASU No. 2016-13, Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), which establishes ASC 326, Financial Instruments – Credit Losses. The ASU revises the measurement of impairment for certain financial instruments measured at amortized cost from an incurred loss methodology to an expected loss methodology. The ASU affects trade receivables, debt securities, net investment in leases, and most other financial assets that represent a right to receive cash. This update is effective for annual and interim financial statement periods beginning after December 15, 2019, with early adoption permitted for financial statement periods beginning after December 15, 2018. In November 2018, the FASB issued ASU No. 2018-19, Codification Improvements to Topic 326, Financial Instruments – Credit Losses. This ASU clarifies that receivables from operating leases are accounted for using the lease guidance and not as financial instruments. The measurement of expected credit losses under the current expected credit loss model is based on relevant information including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amounts. The Partnership adopted the guidance as of January 1, 2020 and recognized $0.1 million as a cumulative adjustment to retained earnings and as a reduction to investments in receivables as of the effective date.

3. Acquisitions and Developments

Drop-down Acquisitions

During the year ended December 31, 2018, the Partnership completed one Drop-down Acquisition from our Sponsor and affiliates. There were no drop-down acquisitions during the years ended December 31, 2020 and 2019. Certain real property interests and financing assets included in the Drop-down Acquisitions completed by the Partnership were part of the right of first offer assets acquired from Landmark Dividend Growth Fund-H LLC (“Fund H”). All other Drop-down Acquisitions have been made directly from our Sponsor or from a wholly owned subsidiary of our Sponsor. The following table presents the Drop-down Acquisitions completed by the Partnership:

		Number of Tenant Sites								Consideration (in millions)
						Renewable				Borrowings
		Wireless		Outdoor		Power				and Available		Common
Acquisition Date	Source	Communication		Advertising		Generation		Total		Cash		Units		Total
January 18, 2018	Fund H		30		90		7		127	$	32.6	$	27.3	$	59.9
2018 Acquisitions			30		90		7		127	$	32.6	$	27.3	$	59.9

Drop-down Acquisitions are accounted for as transfers of net assets between entities under common control. The transfer of net assets is accounted for prospectively in the period in which the transfer occurs at the net carrying value. Any differences between the cash consideration and the net carrying value of the transfer of net assets have been allocated to the General Partner.

Third Party Acquisitions

During the years ended December 31, 2020, 2019 and 2018, the Partnership completed various direct third-party acquisitions. Third-party acquisitions include acquisitions in exchange for Common Units pursuant to our previously filed and effective registration statement on Form

F-15

S-4, in which we may offer and issue, from time to time, an aggregate of up to 5,000,000 Common Units in connection with the acquisition by us or our subsidiaries of other businesses, assets or securities (the “Unit Exchange Program” or “UEP”).

The following table presents direct third-party acquisitions, excluding transaction costs, completed by the Partnership during the years ended December 31, 2020, 2019 and 2018:

Leases

The Partnership evaluates whether an easement meets the definition of a lease under the new lease standard (“ASC 842”). The Partnership determines if an arrangement is a lease at the date of acquisition. The Partnership considers an arrangement to be a lease if it conveys the right to control the use of the leased site or ground space underneath a leased site for a period of time in exchange for consideration. While most of our leases are classified as operating leases in which the Partnership is the lessor, the Partnership is the lessee in an insignificant population of operating and finance leases that have recurring ground lease rental payments. The lease liability is the present value of the remaining minimum rental payments using each respective lease term and a corresponding incremental borrowing rate. We use a weighted-average discount rate of approximately 4.3%, which is the interest rate that we estimate we would have to pay to borrow on a collateralized basis over a similar term for an amount equal to the lease payments. As of December 31, 2020, the weighted-average remaining lease term of operating leases is approximately 8 years. Operating lease assets are included in right of use, net and finance lease assets are included in real property interests in the Consolidated Balance Sheets.

The following table illustrates information about other lease related balances as of December 31, 2020 and 2019 (in thousands):

	December 31,
	2020		2019
Operating leases:
Right-of-use asset	$	10,716	$	6,615
Operating lease liability		8,818		6,766
Finance leases:
Right-of-use asset (1)	$	1,229	$	478

(1) Assets held under finance leases are recorded in Real property interests and are depreciated over the lease term.

Developments

During 2017, the Partnership started developing an ecosystem of technologies that provide smart enabled infrastructure including stealth towers and digital outdoor advertising kiosks across North America. Stealth towers are self-contained, neutral-host towers designed for wireless carrier and other wireless operator collocation. The stealth towers are designed for macro, mini macro and small cell deployments and will support Internet of Things (IoT), carrier densification needs, private LTE networks and other wireless solutions.

During the fourth quarter of fiscal year 2018, the Partnership entered into an agreement with Dallas Area Rapid Transit (“DART”) to develop a smart media and communications platform which will include the deployment of content-rich kiosks and the Partnership’s smart enabled infrastructure ecosystem solution on strategic high-traffic DART locations.

As of December 31, 2020 and 2019, the Partnership’s $44.8 million and $49.1 million, respectively, of construction in progress balance primarily related to these projects, respectively. During the years ended December 31, 2020 and 2019, the Partnership deployed two stealth towers, 112 DART kiosks and placed in service other assets for a total of $16.2 million.

Sales

On June 17, 2020, the Partnership completed the sale of its interest in the consolidated joint venture that holds its European outdoor advertising portfolio for a purchase price of £95 million. We recognized a gain on sale of real property interest of $15.5 million upon completion of the sale. The sale of the European outdoor advertising portfolio has met the criteria as discontinued operations. Accordingly, for all prior periods presented, the related assets and liabilities are presented as assets and liabilities held for sale on the consolidated balance sheets, as described below, and the related operating results and gain on sale are presented as income from discontinued operations on the consolidated statement of operations for all periods presented (Note 9).

During the year ended December 31, 2019, the Partnership completed a sale of two wireless communication sites held for sale and three outdoor advertising sites to a third party in exchange for cash consideration of $1.4 million. We recognized a gain on sale of real property interest of $0.5 million upon completion of the sale.

On June 27, 2019, the Partnership completed a sale of its real property interests and investments in receivables held for sale in its taxable subsidiary for total consideration of $31.8 million. We recognized a gain on sale of real property interests and investments in receivables of $11.7 million before income taxes, or $8.6 million after income taxes, upon completion of the sale.

On January 4, 2019, the Partnership completed the sale of its real property interest held for sale as of December 31, 2018 for total consideration of $13.5 million. We recognized a gain on sale of real property interest of $5.9 million upon completion of the sale.

During the year ended December 31, 2018, the Partnership completed a sale of one outdoor advertising site to a third party in exchange for cash consideration of $0.1 million. We recognized a loss on sale of real property interest of less than $0.1 million upon completion of the sale. Additionally, during the year ended December 31, 2018, the Partnership recognized a gain on the contribution of real property interests of $100 million in connection with the formation of an unconsolidated joint venture (the “JV”) in which 545 tenant sites were contributed to the JV by the Partnership as described in Note 8, Investment in Unconsolidated Joint Venture. The Partnership used $59.7 million of the net proceeds to repay a portion of the borrowings under the revolving credit facility. The Partnership has determined that the contribution does not meet the criteria for discontinued operations presentation as the contribution does not represent a strategic shift that will have a major effect on its operations and financial results and the Partnership has retained an interest in the assets through its interest in the unconsolidated joint venture. 

Purchase Price Allocation

The Partnership applies the asset acquisition method to all acquired investments of real property interests for transactions that meet the definition of an asset acquisition. The fair value of the assets acquired and liabilities assumed is typically determined by using Level III valuation methods. The most sensitive assumption is the discount rate used to discount the estimated cash flows from the real estate rights. For purposes of the computation of fair value assigned to the various tangible and intangible assets, the Partnership assigned discount rates ranging between 6% and 20% with a weighted average discount rate of 8.3%.

F-18

The following table summarizes final allocations for acquisitions made during the years ended December 31, 2020, 2019, and 2018 of estimated fair values of the assets acquired and liabilities assumed (in thousands).

The weighted average remaining depreciation and amortization period for non‑perpetual real property interests is 41 years and 40 years at December 31, 2020 and 2019, respectively.

Impairments

During the year ended December 31, 2020, the Partnership recognized impairment charges totaling $0.3 million for five of the Partnership’s real property interest that were impaired and one non-lease renewal. For the years ended December 31, 2019 and 2018, eight and six of the Partnership’s real property interests were impaired and we recognized impairment charges totaling, $0.7 million and $0.6 million, respectively. The carrying value of each real property interest was determined to have a fair value of zero. Additionally, the Partnership recognized impairment charges related to certain construction in progress of $1.6 million during the year ended December 31, 2019. 

Assets and Liabilities Held for Sale

In December 2016, the Partnership formed a joint venture to acquire real property interests that are leased to companies in the outdoor advertising industry located in the UK and Europe. On June 17, 2020, the Partnership completed the sale of its interest in the European joint venture.

In connection with the sale of the joint venture interest in the European outdoor advertising portfolio, assets totaling $114.4 million and liabilities totaling $64.6 million as of December 31, 2019 were classified as held for sale on the consolidated balance sheets, as presented in the table below.

7. Investments in Receivables

Investments in receivables includes financing arrangements and management agreements whereby we purchased the right to receive a portion of a rental payment under a contract but are not a party to the lease and do not have a real property interest. Additionally, certain lease arrangements of real property interests meet the definition of a financial asset and included in investments in receivables in our financial statements. Investments in receivables also includes arrangements with T‑Mobile whereby we purchased the right to retain a portion of a lease payment prior to passing the remainder to the property owner. The receivables are unsecured with payments collected over periods ranging from 2 to 99 years. These cash flow financing arrangements were recorded at the fair value at the acquisition date, using discount rates ranging from 7% to 14% and are accounted for as receivables in our consolidated financial statements.

During the year ended December 31, 2018, 16 of the Partnership’s investments in receivables were impaired and recognized impairment charges totaling $0.8 million. The investments in receivables were impaired to their net realizable value. Pursuant to the terms of the omnibus agreement, Landmark indemnified the Partnership for the loss related to the impairment of investments in receivables which is treated as a deemed capital contribution.    

Interest income recognized on the receivables totaled $0.5 million, $0.6 million and $1.4 million during 2020, 2019, and 2018, respectively. In connection with the sale of the European outdoor advertising portfolio on June 17, 2020, the Partnership completed the sale of an investment in receivable and recognized a gain on sale of investments in receivables in discontinued operations. Additionally, on June 27, 2019, the Partnership completed a sale of its investments in receivables held for sale as of March 31, 2019 and recognized a gain on sale of investments in receivables.

8. Investment in Unconsolidated Joint Venture

On September 24, 2018, the Partnership completed the formation of the unconsolidated JV. The Partnership contributed 545 tenant site assets to the unconsolidated JV that secured the Partnership’s $125.4 million Series 2018-1 secured notes (the “2018 Securitization”), in exchange for a 50.01% membership interest in the unconsolidated JV and $65.5 million in cash (the “Transaction”). The Partnership does not control the unconsolidated JV and therefore, accounts for its investment in the unconsolidated JV using the equity method of accounting prospectively upon formation of the unconsolidated JV. 

The Partnership recognized a gain on contribution of real property interests in accordance with ASC 610-20, Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets (“ASC 610-20”), which applies to sales or transfers to noncustomers of nonfinancial assets or in substance nonfinancial assets that do not meet the definition of a business. ASC 610-20 refers to the revenue recognition principles under ASU No. 2014-09. Under ASC 610-20, the Partnership determined it does not have a controlling financial interest in the entity that holds the assets and the arrangement meets the criteria to be accounted for as a contract, as such, the Partnership derecognized the assets and recognized a gain on the contribution of the real property interests when control of the underlying assets transferred to the buyer. The gain on the contribution of real property interests is included in the gain on sale of real property interests in the accompanying consolidated statements of operations.

In addition to the contribution of assets, the JV assumed the 2018 Securitization, which was completed by the Partnership on June 6, 2018. The 2018 Securitization financed certain tenant sites and related property interests owned by certain unrestricted special purpose subsidiaries of the Partnership, through the issuance of the Class C, Class D and Class F Series 2018-1 Secured Notes (the “2018 Secured Notes”), in an aggregate principal amount of $125.4 million. The net proceeds from the 2018 Securitization were primarily used to pay down the revolving credit facility by $120.5 million. The Class F notes are subordinated in right of payment to the Class D notes and the Class D notes are subordinated in right of payment to the Class C notes. The 2018 Secured Notes were issued at a discount of less than $0.1 million, which will be accreted and recognized as interest expense over the term of the secured notes. The Class C, Class D and Class F 2018 Secured Notes bear interest at a fixed note rate per annum of 3.97%, 4.70% and 5.92%, respectively.

Revolving Credit Facility

The Partnership’s revolving credit facility with Truist Bank, as administrative agent, and a syndicate of lenders will mature on November 15, 2023 and will be available for working capital, capital expenditures, permitted acquisitions and general partnership purposes, including distributions. On November 15, 2018, the Partnership completed its Third Amended and Restated Credit Facility and obtained commitments from a syndicate of banks with initial borrowing commitments of $450.0 million for five-years. Additionally, borrowings up to $75.0 million may be denominated in GBP, Euro, Australian dollar and Canadian dollar. Substantially all of our assets, excluding equity in and assets of unrestricted subsidiaries, after‑acquired real property (other than real property that is acquired from affiliate funds and is subject to a mortgage), and other customary exclusions, are pledged (or secured by mortgages), as collateral under our revolving credit facility. Our revolving credit facility contains various customary covenants and restrictive provisions.

In addition, our revolving credit facility contains customary events of default, including, but not limited to (i) event of default resulting from our failure or the failure of our restricted subsidiaries to comply with covenants and financial ratios, (ii) the occurrence of a change of control (as defined in the credit agreement), (iii) the institution of insolvency or similar proceedings against us or our restricted subsidiaries, (iv) the occurrence of a default under any other material indebtedness (as defined in the credit agreement) we or our restricted subsidiaries may have and (v) any one or more collateral documents ceasing to create a valid and perfected lien on collateral (as defined in the credit agreement). Upon the occurrence and during the continuation of an event of default, subject to the terms and conditions of the credit agreement, the lenders may declare any outstanding principal of our revolving credit facility debt, together with accrued and unpaid interest, to be immediately due and payable and may exercise the other remedies set forth or referred to in the credit agreement and the other loan documents.

Loans under the revolving credit facility bear interest at a rate equal to LIBOR related to the currency for which borrowings are denominated, plus a spread ranging from 1.75% to 2.25% (determined based on leverage levels). As of December 31, 2020, the applicable spread was 2.25%.

Additionally, under the revolving credit facility we will be subject to an annual commitment fee (determined based on leverage levels) associated with the available undrawn capacity subject to certain restrictions. As of December 31, 2020, the applicable annual commitment rate used was 0.20%.

The revolving credit facility requires monthly interest payments and the outstanding debt balance is due upon maturity on November 15, 2023. In June 2020, the Partnership used proceeds from the sale of the European outdoor advertising portfolio and available cash to repay borrowings totaling $115 million on its revolving credit facility, including the £40.5 million of GBP denominated borrowings. As of December 31, 2020, $214.2 million was outstanding. Our revolving credit facility contains various covenants and restrictive provisions that limit our ability (as well as the ability of our restricted subsidiaries) to incur or guarantee additional debt, among other things. As of December 31, 2020 there was $235.8 million of undrawn borrowing capacity (including standby letter of credit arrangements of $5.8 million), subject to compliance with various financial covenants. As of December 31, 2020 and 2019, the Partnership was in compliance with all financial covenants required under the revolving credit facility.

Secured Notes

On January 15, 2020, certain subsidiaries of the Partnership entered into a master note purchase and participation agreement (“MNPPA”) pursuant to which such subsidiaries issued and sold an initial $170 million aggregate principal amount of 3.90% series A senior secured notes in a private placement (the “2019 Secured Notes”). The 2019 Secured Notes mature on January 14, 2027 and include an interest-only initial term of three years. The net proceeds were used to repay in full the 2016 Secured Notes by $108 million and the revolving credit facility by $59 million. In connection with the issuance of the senior secured notes, the Partnership obtained a standby letter of credit arrangement totaling $3.4 million.

On April 24, 2018, the Partnership entered into a note purchase and private shelf agreement (the “Note Purchase Agreement”) pursuant to which the Partnership agreed to sell an initial $43.7 million aggregate principal amount of 4.38% senior secured notes, in a private placement (the “4.38% Senior Secured Notes”) involving a segregated pool of renewable power generation sites and related property interests. The 4.38% Senior Secured Notes are fully amortized through June 30, 2036. We used all the net proceeds of $41.0 million to repay a portion of the borrowings under our revolving credit facility. In connection with the issuance of the 4.38% Senior Secured Notes, the Partnership obtained a standby letter of credit arrangement totaling $2.4 million.

F-24

On November 30, 2017, the Partnership completed a securitization transaction (the “2017 Securitization”) involving certain outdoor advertising tenant sites and related property interests owned by certain unrestricted special purpose subsidiaries of the Partnership, through the issuance of the Series 2017-1 Secured Notes, Class A and Class B (the “2017 Secured Notes”), in an aggregate principal amount of $80.0 million. The net proceeds from the 2017 Securitization were primarily used to pay down the revolving credit facility by $54.0 million and $17.5 million held in a restricted reserve accounts, including $16.0 million into a site acquisition account to be used to acquire additional tenant sites pursuant to the Indenture. The Class B notes are subordinated in right of payment to the Class A notes. The 2017 Secured Notes were issued at a discount of $1.8 million, which will be accreted and recognized as interest expense over the term of the secured notes. The Class A and Class B 2017 Secured Notes bear interest at a fixed note rate per annum of 4.10% and 3.81%, respectively. The Partnership is required to make monthly payments of principal and interest on Class A and Class B 2017 Secured Notes based on a 30-year amortization period, commencing in January 2018. On each payment date on and after the payment date occurring in January 2018, available funds are used to repay the Class A 2017 Secured Notes in an amount sufficient to pay the Class A 2017 Secured Notes monthly amortization amount and to repay the Class B 2017 Secured Notes in an amount sufficient to pay the Class B 2017 Secured Notes monthly amortization amount on such payment date. No other payments of principal will be required to be made prior to the anticipated repayment date in November 2022.

The secured notes described above are collectively referred to as the “Secured Notes” and the tenant site assets securing the Secured Notes are collectively referred to as the “Secured Tenant Site Assets.”

The Secured Notes are secured by (1) mortgages and deeds of trust on substantially all of the Secured Tenant Site Assets and their operating cash flows, (2) a security interest in substantially all of the personal property of the obligors (as defined in the applicable indenture), and (3) the rights of the obligors under a management agreement. Under the terms of the applicable indenture, amounts due under the Secured Notes will be paid solely from the cash flows generated from the operation of the Secured Tenant Site Assets, as applicable, which must be deposited into reserve accounts, and thereafter distributed solely pursuant to the terms of the applicable indenture. On a monthly basis, after payment of all required amounts under the applicable indenture, subject to the conditions described below, the excess cash flows generated from the operation of such assets are released to the Partnership. As of December 31, 2020 and 2019, $3.2 million and $5.6 million was held in such reserve accounts which are classified as Restricted Cash on the accompanying consolidated balance sheets.

Certain information with respect to the 2019 and 2017 Securitization is set forth below. The debt service coverage ratio (“DSCR”) is generally calculated as the ratio of annualized net cash flow (as defined in the applicable indenture) to the amount of interest, servicing fees and trustee fees required to be paid over the succeeding 12 months on the principal amount of the Secured Notes, as applicable, that will be outstanding on the payment date following such date of determination.

			Conditions Limiting Distributions of Excess Cash
	Issuer or Borrower	Notes Issued	Cash Trap DSCR	Amortization Period
2019 Securitization	LMRK Issuer Co. LLC, 2019-1 TRS LLC	Series A Senior Secured Notes	1.30x (1)	(1)
2017 Securitization	LMRK Issuer Co. 2 LLC	Series 2017-1 Secured Notes, Class A and Class B	1.30x (2)	(3)

(1) An amortization period will commence (at the option of the related noteholder) if the debt service coverage ratio (measured for the most recently ended period of 12 consecutive months) falls below 1.30 to 1.00 on such calculation date. During an amortization period, excess cash flow will be applied to repay the applicable notes.

(2) Once triggered, a Cash Trap DSCR condition continues to exist until the DSCR exceeds the Cash Trap DSCR for two consecutive calendar months. During a Cash Trap DSCR condition, all cash flow in excess of amounts required to make debt service payments, to fund required reserves, to pay management fees and budgeted operating expenses and to make other payments required under the indenture, referred to as excess cash flow, will be deposited into a reserve account instead of being released to the applicable issuer.

(3) An amortization period commences if the DSCR is equal to or below 1.15x (the “Minimum DSCR”) at the end of any calendar month and continues to exist until the DSCR exceeds the Minimum DSCR for two consecutive calendar months.

The Partnership is subject to covenants customary for notes issued in rated securitizations. Among other things, the obligors are prohibited from incurring other indebtedness for borrowed money or further encumbering their assets (as defined in the applicable agreement). Under the terms of the applicable indenture, the obligors will be permitted to issue additional notes under certain circumstances, including so long as the DSCR of the issuer is at least 1.5x to 1.0x for the 2019 Secured Notes and at least 2.0x to 1.0x for the 2017 Secured Notes. As of December 31, 2020, the Partnership was in compliance with all financial covenants required under the Secured Notes.

F-25

Other Secured Debt

On September 25, 2020, the Partnership assumed a Property Assessed Clean Energy (“PACE”) special assessment bond of $3.5 million in connection with a data center acquisition during the third quarter of 2020. The financing agreement is a previous owner-arranged financing agreement dated July 1, 2018 in which PACE bonds were issued by local municipality to the then current property owner for the purpose of financing energy efficiency improvements to the property. These bonds are secured by the property and mature on February 14, 2038. Payments are made semi-annually over the term. The Partnership has assumed the secured debt, which is included in secured notes, net in the Consolidated Balance Sheet.

The Secured Notes’ annual principal payment amounts due as of December 31, 2020, are as follows (in thousands):

Interest Expense

For the years ended December 31, 2020, 2019 and 2018, the Partnership incurred interest expense, excluding amounts related to discontinued operations, of $17.3 million, $17.5 million and $24.3 million, respectively, and had interest payable of $0.3 million and $0.5 million as of December 31, 2020 and 2019, respectively. Additionally, the Partnership recorded deferred loan costs and amortization of discount on secured notes, which is included in interest expense, of $2.5 million, $3.1 million and $3.8 million for the years ended December 31, 2020, 2019 and 2018, respectively. In connection with the amendment of the credit facility on November 15, 2018, the unamortized balance of the deferred loan costs totaling $0.2 million was recorded as a loss on extinguishment of debt during the year ended December 31, 2018.

During the years ended December 31, 2020, 2019 and 2018, the Partnership recorded a loss, excluding amounts related to discontinued operations, of $6.2 million, a loss of $6.1 million and a gain of $1.4 million, respectively, resulting from the change in fair value of the interest rate swap agreements which is reflected as an unrealized gain (loss) on derivatives on the consolidated statements of operations. In June 2020, the Partnership used proceeds from the sale of the European outdoor advertising portfolio to terminate certain interest rate swap agreements for approximately $7.6 million, including approximately $3.3 million for the GBP denominated interest rate swap agreement with a notional value of £38 million. As of December 31, 2019, the GBP swap agreement had a fair value liability of $1.7 million, which was reclassified to liabilities held for sale in prior period to exclude discontinued operations (Note 4). Additionally, for all periods presented, foreign currency transaction gains and losses resulting from the changes in exchange rates affecting mark-to-market adjustments on the GBP interest rate swap agreement were reclassified to discontinued operations (Note 9).

F-26

The fair value of the interest rate swap agreements is derived based on Level 2 inputs. To illustrate the effect of movements in the interest rate market, the Partnership performed a market sensitivity analysis on its outstanding interest rate swap agreements. The Partnership applied various basis point spreads to the underlying interest rate curve of the derivative in order to determine the instruments’ value including change in fair value at December 31, 2020. The following table summarizes the results of the analysis performed (in thousands):

		Sensitivity of the Fair Value to Changes in Interest Rates

12. Unit-Based Compensation 

Compensation of our Directors

On January 25, 2018 the board of directors of the General Partner adopted the Amended and Restated Non-Employee Director Compensation Plan that provides each director that is neither an officer of the General Partner nor an employee or an affiliate of the General Partner with annualized compensation consisting of $40,000 in cash, payable quarterly, and an annual grant of Common Units valued at $40,000 and additional cash compensation for attending meetings of the board of directors of the General Partner or a committee thereof. Additionally, the chairman of the audit committee of the board of directors shall be entitled to additional annualized cash compensation of $15,000 and the chairman of any other committee of the board of directors, as may be established at any time, shall be entitled to an amount in cash as determined by the board of directors.

Our Long‑Term Incentive Plan

In connection with the IPO, the board of directors of the General Partner adopted the Landmark Infrastructure Partners LP 2014 Long-Term Incentive Plan (the “LTIP”). The LTIP provides for the grant, from time to time at the discretion of the board of directors of the General Partner or any committee thereof that may be established for such purpose or by any delegate of the board of directors or such committee, subject to applicable law (the “plan administrator”), of equity-based awards. The purpose of the LTIP is to promote the interests of the Partnership and the General Partner by providing incentive compensation awards to individuals providing services to the Partnership or the General Partner to encourage superior performance. The LTIP is also intended to enhance the ability of the Partnership and the General Partner to attract and retain the services of individuals who are essential for the growth and profitability of the Partnership and the General Partner and to encourage these individuals to devote their best efforts to advancing the business of the Partnership and the General Partner. The LTIP will initially limit the number of units that may be delivered pursuant to vested awards to 785,000 Common Units, subject to proportionate adjustment in the event of unit splits and similar events, with such amount increased annually on the first day of each calendar year beginning January 1, 2016 and ending on and including January 1, 2024 by a number of Common Units equal to the least of (i) 1,570,000 Common Units, (ii) 2% of the total number of common units outstanding on the last day of the immediately preceding calendar year and (iii) such smaller number of Common Units as determined by the board of directors of the General Partner. Common Units subject to awards that are cancelled, forfeited, withheld to satisfy exercise prices or tax withholding obligations, or otherwise terminated without delivery of the Common Units will be available for delivery pursuant to other awards. We have granted 7,368, 10,631 and 3,826 units under our LTIP as compensation to our Non-Employee Directors during the years ended December 31, 2020, 2019 and 2018, respectively, and no other awards were granted to any of our executive officers.

On December 4, 2019, the Partnership filed a universal shelf registration statement on Form S-3 with the SEC. The shelf registration statement was declared effective by the SEC on January 30, 2020 and permits us to issue and sell, from time to time, common and preferred units representing limited partner interests in us, and debt securities up to an aggregate amount of $750.0 million.

Common Units

On February 16, 2016, the Partnership filed a shelf registration statement on Form S-4 with the SEC. The shelf registration statement was declared effective on March 10, 2016 and permits us to offer and issue, from time to time, an aggregate of up to 5,000,000 Common Units in connection with the acquisition by us or our subsidiaries of other businesses, assets or securities. No acquisitions were completed during the year ended December 31, 2020 and 2019 under the Unit Exchange Program. During the year ended December 31, 2018, under the Unit Exchange Program we completed acquisitions of 28 tenant sites in exchange for 508,157 Common Units, valued at approximately $7.6 million.

On February 16, 2016, the Partnership established a Common Unit at-the-market offering program (the “2016 Common Unit ATM Program”) that expired on December 30, 2018, therefore, no Common Units were issued under the 2016 Common Unit ATM Program during the years ended December 31, 2020 and 2019. During the year ended December 31, 2018, the Partnership issued 27,830 Common Units under the 2016 Common Unit ATM Program, generating proceeds of approximately $0.5 million before issuance costs.

On May 3, 2019, the Partnership established a Common Unit at-the-market offering program (the “2019 Common Unit ATM Program”) pursuant to which we may sell, from time to time, Common Units having an aggregate offering price of up to $50.0 million pursuant to our previously filed and effective registration statement on Form S-3. The net proceeds from sales under the 2019 Common Unit ATM Program will be used for general partnership purposes, which may include, among other things, the repayment of indebtedness and to potentially fund future acquisitions. During the year ended December 31, 2020, 109,724 Common Units were issued under the 2019 Common Unit ATM Program generating proceeds of approximately $1.8 million before issuance costs. No Common Units were issued under the 2019 Common Unit ATM Program during the year ended December 31, 2019.

On February 28, 2020, the Partnership replaced the 2019 Common Unit ATM Program and established a new Common Unit at-the-market offering program (the “2020 Common Unit ATM Program”) pursuant to which we may sell, from time to time, Common Units having an aggregate offering price of up to $50.0 million pursuant to our previously filed and effective registration statement on Form S-3. The net proceeds from sales under the 2020 Common Unit ATM Program will be used for general partnership purposes, which may include, among other things, the repayment of indebtedness and to potentially fund future acquisitions. No Common Units were issued under the 2020 Common Unit ATM Program during the year ended December 31, 2020.

Subordinated Units

Our Partnership Agreement provides that, during the subordination period, the Common Units have the right to receive distributions of available cash from operating surplus each quarter in an amount equal to $0.2875 per Common Unit, which amount is defined in our Partnership Agreement as the minimum quarterly distribution, plus any arrearages in the payment of the minimum quarterly distribution on the Common Units from prior quarters, before any distributions of available cash from operating surplus may be made on the subordinated units. These units are deemed “subordinated” because for a period of time, referred to as the subordination period, the subordinated units are not entitled to receive any distributions until the Common Units have received the minimum quarterly distribution plus any arrearages in the payment of the minimum quarterly distribution on the Common Units from prior quarters. Furthermore, no arrearages will accrue or be payable on the subordinated units. The practical effect of the subordinated units is to increase the likelihood that, during the subordination period, there will be available cash to be distributed on the Common Units. The requirements under our Partnership Agreement for the conversion of all the subordinated units into common units were satisfied upon the payment of our quarterly cash distribution on February 14, 2018. Therefore, effective February 15, 2018, all of our subordinated units which are owned by Landmark, were converted on a one-for-one basis into common units. The conversion of subordinated units does not impact the amount of cash distributions or total number of outstanding units.

Preferred Units

On June 24, 2016, the Partnership established a Series A Preferred Unit at-the-market offering program (the “2016 Series A Preferred Unit ATM Program”), that expired on December 30, 2018, therefore, no Series A Preferred Units were issued under the 2016 Series A ATM Program during the years ended December 31, 2020 and 2019. During the year ended December 31, 2018, the Partnership issued 24,747 Series A Preferred Units under the 2016 Series A Preferred Unit ATM Program, generating proceeds of approximately $0.6 million before issuance costs.   

On March 30, 2017, the Partnership established a Series B Preferred Unit at-the-market offering program (the “Series B Preferred Unit ATM Program”), pursuant to which we may sell, from time to time, Series B Preferred Units having an aggregate offering price of up to $50.0 million pursuant to our previously filed and effective registration statement on Form S-3. The net proceeds from sales under the Series B Preferred Unit ATM Program will be used for general Partnership purposes, which may include, among other things, the repayment of indebtedness and to potentially fund future acquisitions. During the year ended December 31, 2020 and 2019, the Partnership issued 84,139 and 81,778 Series B Preferred Units, respectively, under our Series B Preferred Unit ATM Program, generating proceeds of approximately $2.2 million and $2.1 million before issuance costs, respectively. No Series B Preferred Units were issued under our Series B Preferred Unit ATM Program during the year ended December 31, 2018. As of December 31, 2020, we have $30.2 million remaining available to be issued under the Series B Preferred Unit ATM Program.

On May 3, 2019, the Partnership established a Series A Preferred Unit at-the-market offering program (the “2019 Series A ATM Program” and together with the 2016 Series A Preferred Unit ATM Program, Series B Preferred Unit ATM Program and Common Unit ATM Program the “ATM Programs”) pursuant to which we may sell, from time to time, Series A Preferred Units having an aggregate offering price of up to $50.0 million pursuant to our previously filed and effective registration statement on Form S-3. The net proceeds from sales under the 2019 Series A ATM Program will be used for general Partnership purposes, which may include, among other things, the repayment of indebtedness and to potentially fund future acquisitions. During the year ended December 31, 2020 and 2019, the Partnership issued 23,287 and 128,892 Series A Preferred Units, respectively, under our 2019 Series A ATM Program, generating proceeds of approximately $0.6 million and $3.3 million, respectively before issuance costs. As of December 31, 2020, we have $46.1 million remaining available to be issued under the 2019 Series A ATM Program.

On February 28, 2020, the Partnership replaced the 2019 Series A ATM Program and established a new Series A Preferred Unit at-the-market offering program (the “2020 Series A ATM Program”) pursuant to which we may sell, from time to time, Series A Preferred Units having an aggregate offering price of up to $50.0 million pursuant to our previously filed and effective registration statement on Form S-3. The net proceeds from sales under the 2020 Series A ATM Program will be used for general partnership purposes, which may include, among other things, the repayment of indebtedness and to potentially fund future acquisitions. During the year ended December 31, 2020, the Partnership issued 43,515 Series A Preferred Units under our 2020 Series A ATM Program, generating proceeds of approximately $1.1 million before issuance costs.

On February 28, 2020, the Partnership replaced the Series B ATM Program and established a new Series B Preferred Unit at-the-market offering program (the “2020 Series B ATM Program”) pursuant to which we may sell, from time to time, Series B Preferred Units having an aggregate offering price of up to $50.0 million pursuant to our previously filed and effective registration statement on Form S-3. The net proceeds from sales under the 2020 Series B ATM Program will be used for general partnership purposes, which may include, among other things, the repayment of indebtedness and to potentially fund future acquisitions. No Series B Preferred Units were issued under the 2020 Series B ATM Program during the year ended December 31, 2020.

Mezzanine Equity

On April 2, 2018, the Partnership completed a public offering of 2,000,000 Series C Floating-to-Fixed Rate Cumulative Perpetual Redeemable Convertible Preferred Units (“Series C Preferred Units” and together with the Series A Preferred Units and Series B Preferred Units the “Preferred Units”), representing limited partner interest in the Partnership, at a price of $25.00 per unit. We received net proceeds of approximately $47.5 million after deducting underwriters’ discounts and offering expenses paid by us of $2.5 million. We used substantially all net proceeds to repay a portion of the borrowings under our revolving credit facility. In connection with the closing of the Series C Preferred Units offering, the Partnership executed the Fourth Amended and Restated Agreement of Limited Partnership of Landmark Infrastructure Partners LP (the “Amended Partnership Agreement”) for the purpose of defining the preferences, rights, powers and duties of holders of the Series C Preferred Units.

Distributions on the Series C Preferred Units are cumulative from the date of original issue and will be payable quarterly in arrears on the 15th day of February, May, August and November of each year, when, as and if declared by the board of directors of our General Partner. The initial distribution on the Series C Preferred Units was paid on May 15, 2018 in an amount equal to $0.2090 per unit. Distributions accruing from, and including, the date of original issuance and to, but excluding May 15, 2025 will accrue at an annual rate equal to the greater of (i) 7.00% per annum, and (ii) the sum of (a) three-month LIBOR as calculated on each applicable date of determination and (b) 4.698% per annum, based on the $25.00 liquidation preference per Series C Preferred Unit. Distributions accruing on and after May 15, 2025 will accrue at 9.00% per annum of the stated liquidation preference.

Holders of Series C Preferred Units, at their option, may, at any time and from time to time, convert some or all of their Series C Preferred Units based on an initial conversion rate of 1.3017 common units per Series C Preferred Unit. In the event of a fundamental change, holder of the Series C Preferred Units, at their option, may convert some or all of their Series C Preferred Units into the greater of (i) a number of common units plus a make-whole premium and (ii) a number of common units equal to the lessor of (a) the liquidation preference divided by the market value of our common units on the effective date of such fundamental change and (b) 11.13 (subject to adjustments). On May 15, 2025, May 15, 2028, and each subsequent five-year anniversary date thereafter (each such date, a “designated redemption date”), each holder of Series C Preferred Units shall have the right (a “redemption right”) to require the Partnership to redeem any or all of the Series C Preferred Units held by such holder outstanding on such designated redemption date at a redemption price equal to the liquidation preference of $25.00, plus all accrued and unpaid distributions to, but not including, in each case out of funds legally available for such payment and to the extent not prohibited by law, the designated redemption date (the “put redemption price”). At our option we may pay the redemption in our common units or cash, subject to certain limitations.

At any time on or after May 20, 2025, the Partnership shall have the option to redeem the Series C Preferred Units, in whole or in part, at a redemption price of $25.00 per Series C Preferred Unit plus an amount equal to all accumulated and unpaid distributions thereon to the date of redemption, whether or not declared.

The Partnership has classified the Series C Preferred Units as mezzanine equity in the accompanying consolidated balance sheets based upon the terms and conditions of the holder’s redemption option. Issuance costs related to the Series C Preferred Units classified as mezzanine equity are initially recorded as a reduction of the units balances and accreted up to the redemption value. During the years ended December 31, 2020 and 2019, 6,000 and 11,300 Series C Preferred Units were converted into 7,810 and 14,708 Common Units, respectively, based on the holder’s option.

14. Net Income (Loss) Per Limited Partner Unit

Landmark’s subordinated units and the General Partner’s incentive distribution rights meet the definition of a participating security and therefore we are required to compute income per unit using the two-class method under which any excess of distributions declared over net income shall be allocated to the partners based on their respective sharing of income specified in the Amended Partnership Agreement. Payments made to our unitholders are determined in relation to actual distributions declared and are not based on the net income (loss) allocations used in the calculation of net income (loss) per unit.

Net income (loss) per unit applicable to limited partners (including subordinated unitholders) is computed by dividing limited partners’ interest in net income (loss), after deducting any Preferred Unit distributions and General Partner incentive distributions, by the weighted-average number of outstanding common and subordinated units. Diluted net income (loss) per unit includes the effects of potentially dilutive units on our common and subordinated units and Series C Preferred Units. Net income (loss) related to the Drop-down Assets prior to the Partnership’s acquisition dates of each transaction is allocated to the General Partner.

Effective February 15, 2018, all of our subordinated units, which were owned by Landmark, were converted on a one-for-one basis into common units. The subordinated units were only allocated the excess of distributions declared over net income through the conversion date.

The calculation of the undistributed net loss attributable to common and subordinated unitholders for the years ended December 31, 2020, 2019 and 2018 is as follows (in thousands):

	Year Ended December 31,
	2020			2019			2018

(1) The General Partner irrevocably waived its right to receive the incentive distribution and incentive allocations related to each quarterly distribution during the year ended December 31, 2019 and for the three months ended September 30, 2018 and December 31, 2018. For purposes of determining net income per common unit, the amount otherwise due to the general partner has been referenced as a deemed distribution.

(1) Diluted earnings per unit takes into account the potential dilutive effect of common units that could be issued by the Partnership in conjunction with the Series C Preferred Units conversion features. Potential common unit equivalents are anti-dilutive for the years ended December 31, 2020 and 2019 and, as a result, have been excluded in the determination of diluted income (loss) from continuing operations per common unit and net income (loss) per common unit. Potential common unit equivalents were dilutive for the year ended December 31, 2018 and, as a result, have been included in the determination of diluted income (loss) from continuing operations per common and subordinated unit and net income (loss) per common and subordinated unit.

(2) The Partnership Agreement provides that when the subordination period ends, each outstanding subordinated unit will convert into one Common Unit and will thereafter participate pro rata with the other Common Units in distributions of available cash. Effective February 15, 2018, all of the subordinated units, which were owned by Landmark, were converted on a one-for-one basis into Common Units. The diluted effect of Landmark’s subordinated units is reflected using the “if-converted method” which assumes conversion of the subordinated units into Common Units and excludes the subordinated distributions from the calculation, as the “if-converted method” is more dilutive.

15. Fair Value of Financial Instruments

The fair value for certain financial instruments is derived using a combination of market quotes, pricing models and other valuation techniques that involve significant management judgment. The price transparency of financial instruments is a key determinant of the degree of judgment involved in determining the fair value of the Partnership’s financial instruments. Financial instruments for which actively quoted prices or pricing parameters are available and for which markets contain orderly transaction will generally have a higher degree of price transparency than financial instruments for which markets are inactive or consist of non‑orderly trades. The Partnership evaluates several factors when determining if a market is inactive or when market transactions are not orderly. The following is a summary of the methods and assumptions used by management in estimating the fair value of each class of assets and liabilities for which it is practicable to estimate the fair value:

Cash and cash equivalents, rent receivables, net accounts payable and accrued liabilities:  The carrying values of these balances approximate their fair values because of the short‑term nature of these instruments.

F-33

Revolving credit facility:  The fair value of the Partnership’s revolving credit facility is estimated using a discounted cash flow analysis based on management’s estimates of current market interest rates for instruments with similar characteristics, including remaining loan term, loan‑to‑value ratio, type of collateral and other credit enhancements. Additionally, since a quoted price in an active market is generally not available for the instrument or an identical instrument, the Partnership measures fair value using a valuation technique that is consistent with the principles of fair value measurement which typically considers what management believes is a market participant rate for a similar instrument. The Partnership classifies these inputs as Level 3 inputs. The fair value of the Partnership’s revolving credit facility is considered to approximate the carrying value because the interest payments are based on LIBOR rates that reset every month.

Secured notes: The Partnership determines fair value of its secured notes utilizing various Level 2 sources including quoted prices and indicative quotes (non-binding quotes) from brokers that require judgment to interpret market information. Quotes from brokers require judgment and are based on the brokers’ interpretation of market information, including implied credit spreads for similar borrowings on recent trades or bid/ask prices or quotes from active markets if available.

Investments in receivables:  The Partnership’s investments in receivables are presented in the accompanying consolidated balance sheets at their amortized cost net of recorded reserves and not at fair value. The fair values of the receivables were estimated using an internal valuation model that considered the expected cash flow of the receivables and estimated yield requirements by market participants with similar characteristics, including remaining loan term, and credit enhancements. The Partnership classifies these inputs as Level 3 inputs.

Interest rate swap agreements:  The Partnership’s interest rate swap agreements are presented at fair value on the accompanying consolidated balance sheets. The valuation of these instruments is determined using a proprietary model that utilizes observable and unobservable inputs. A majority of the inputs are observable with the only unobservable inputs relating to the lack of performance risk on the part of the Partnership or the counter party to the instrument. As such, the Partnership classifies these inputs as Level 2 inputs. The proprietary model uses the contractual terms of the derivatives, including the period to maturity, as well as observable market‑based inputs, including the interest rate curves and volatility. The fair values of interest rate swaps are estimated using the market standard methodology of netting the discounted fixed cash payments and the discounted expected variable cash receipts. The variable cash receipts are based on an expectation of interest rates (forward curves) derived from observable market interest rate curves. In addition, credit valuation adjustments, which consider the impact of any credit risk to the contracts, are incorporated in the fair values to account for potential nonperformance risk.

The table below summarizes the carrying amounts and fair values of financial instruments which are not carried at fair value on the face of the financial statements. Prior period amounts have been revised to exclude discontinued operations (in thousands):

	December 31,
	2020				2019
	Carrying amount		Fair Value		Carrying amount		Fair Value
Investments in receivables, net	$	5,101	$	5,105	$	5,653	$	5,650
Revolving credit facility		214,200		214,200		179,500		179,500
Secured Notes, net		279,677		298,097		217,098		221,577

Disclosure of the fair values of financial instruments is based on pertinent information available to the Partnership as of the period end and requires a significant amount of judgment. Despite increased capital market and credit market activity, transaction volume for certain financial instruments remains relatively low. This has made the estimation of fair values difficult and, therefore, both the actual results and the Partnership’s estimate of value at a future date could be materially different.

For the years ended December 31, 2020 and 2019, the Partnership measured the following assets and liabilities at fair value on a recurring basis. Prior period amount has been revised to exclude discontinued operations (in thousands):

	December 31,
	2020		2019
Derivative Liabilities(1)	$	3,435	$	1,474

(1) Fair value is calculated using level 2 inputs. Level 2 inputs are quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model‑derived valuations in which significant inputs and significant value drivers are observable in active markets.

16. Related‑Party Transactions

General and Administrative Reimbursement

Under the Amended Partnership Agreement, we are required to reimburse our general partner and its affiliates for all costs and expenses that they incur on our behalf for managing and controlling our business and operations. Except to the extent specified under our amended Omnibus Agreement with Landmark (the “Omnibus Agreement”), which was amended on January 30, 2019, our general partner determines the amount of these expenses and such determinations must be made in good faith under the terms of the Amended Partnership Agreement. Under the amended Omnibus Agreement, we are required to reimburse Landmark for expenses related to certain general and administrative services Landmark provides to us in support of our business, subject to a quarterly cap equal to 3% of our revenue during the current calendar quarter. This cap on expenses will last until the earlier to occur of: (i) the date on which our revenue for the immediately preceding four consecutive fiscal quarters exceeded $120 million and (ii) November 19, 2021. The full amount of general and administrative expenses incurred will be reimbursed by Landmark and reflected on our income statements, and to the extent such general and administrative expenses exceed the cap amount, the amount of such excess will be reflected in our financial statements as a capital contribution rather than as a reduction of our general and administrative expenses, except for expenses that would otherwise be allocated to us, which are not included in the amount of general and administrative expenses. These expenses include salary, bonus, incentive compensation and other amounts paid to persons who perform services for us or on our behalf and expenses allocated to our general partner by its affiliates. For the years ended December 31, 2020, 2019 and 2018, Landmark reimbursed us $3.0 million, $3.7 million and $2.8 million, respectively, for expenses related to certain general and administrative services that exceeded the cap. During the years ended December 31, 2020, 2019 and 2018, $0.3 million, $0.3 million and less than $0.1 million, respectively, of management fees related to our unconsolidated joint venture that is not subject to the cap and is treated as a capital contribution from Sponsor. Additionally, indemnification of $0.4 million related to property taxes is included in capital contributions from Sponsor on the Consolidated Statements of Equity and Mezzanine Equity for 2019. Additionally, indemnification of $1.0 million related to certain assets and is included in capital contributions from Sponsor on the Consolidated Statement of Equity and Mezzanine Equity for 2018.

Patent License Agreement

We entered into a Patent License Agreement (the “License Agreement”) with American Infrastructure Funds, LLC (“AIF”), an affiliate of the controlling member of Landmark. Under the License Agreement, AIF granted us a nonexclusive, perpetual license to practice certain patented methods related to the apparatus and method for combining easements under a master limited partnership. We have agreed to pay AIF a license fee of $50,000 for the second year of the License Agreement, and thereafter, an amount equal to the greater of (i) one‑tenth of one percent (0.1%) of our gross revenue received during such contract year; or (ii) $100,000. During the years ended December 31, 2020, 2019 and 2018, we incurred $0.1 million, respectively, of license fees related to the AIF patent license agreement.

Right of First Offer

In accordance with the Partnership’s omnibus agreement, certain other investment funds managed by Landmark had granted us a right of first offer (“ROFO”) on real property interests that they owned or acquired before selling or transferring those assets to any third party. During the years ended December 31, 2018, the Partnership waived its ROFO on certain assets in investment funds managed by Landmark. During the year ended December 31, 2018, the Partnership completed the following ROFO acquisitions:

										Common Units
				Total No. of		Total		Total		Issued to
	Acquired	Total No.		Investments in		Consideration		Common Units		Landmark
Acquisition Date	Fund	of Tenant Sites		Receivables		(in millions)		Issued		and Affiliates
January 18, 2018	Fund H		127		—	$	59.9		1,506,421		—

See further discussion in Note 3, Acquisitions for additional information.

Secured Tenant Site Assets’ Management Fee

In connection with the issuance of the Secured Notes, the Partnership entered into applicable management agreements with the General Partner. Pursuant to the applicable management agreements, our General Partner will perform those functions reasonably necessary to maintain, manage and administer the Secured Tenant Site Assets for a monthly management fee equal to (i) 1.5% of the Secured Tenant Site Assets’ operating revenue, as defined by the applicable management agreements for the 2017 secured notes; (ii) 0.5% of operating revenue for the 4.38% senior secured notes and (iii) 2% of gross revenue for the 2019 secured notes. The Secured Tenant Site Assets’ management fee to Landmark will be treated as a capital distribution to Landmark. Landmark will reimburse us for the fees paid with the reimbursement treated as a capital contribution. We incurred $0.1 million, $0.3 million and less than $0.1 million of Secured Tenant Site Assets’ management fees during the years ended December 31, 2020, 2019 and 2018, respectively.

F-35

In connection with the formation of the unconsolidated JV, the JV assumed the 2018 Secured Notes. Pursuant to the applicable management agreement, our General Partner will perform those functions reasonably necessary to maintain, manage and administer the 2018 Secured Tenant Site Assets for a monthly management fee equal to 1.5% of the Secured Tenant Site Assets’ operating revenue, subject to a maximum of $46 per tenant site asset. Landmark will reimburse us for the management fees paid by the unconsolidated JV with the reimbursement treated as a capital contribution. For the years ended December 31, 2020, 2019 and 2018, the unconsolidated JV incurred $0.3 million, $0.3 million and $0.1 million of management fees and included in capital contributions from Sponsor on the Consolidated Statement of Equity and Mezzanine Equity.

Acquisition of Real Property Interests

In connection with third party acquisitions, Landmark will be obligated to provide acquisition services to us, including asset identification, underwriting and due diligence, negotiation, documentation and closing, at the reasonable request of our General Partner, but we are under no obligation to utilize such services. We may pay Landmark reasonable fees, as mutually agreed to by Landmark and us, for providing these services. These fees will not be subject to the cap on general and administrative expenses described above. During the year ended December 31, 2020, the Partnership incurred $4.3 million of acquisition fees related to the third and fourth quarter 2020 direct acquisitions. There were no such fees incurred during the years ended December 31, 2019 and 2018.

Incentive Distribution Rights

Cash distributions will be made to our General Partner in respect of its ownership of all IDRs, which entitle our General Partner to receive increasing percentages, up to a maximum of 50%, of the available cash we distribute from operating surplus (as defined in our Amended Partnership Agreement) in excess of $0.2875 per unit per quarter. There were no incentive distributions and incentive allocations during the year ended December 31, 2020. The General Partner irrevocably waived its right to receive the incentive distribution and incentive allocations related to each quarterly distribution during the year ended December 31, 2019 and for the three months ended September 30, 2018 and December 31, 2018, totaling $0.8 million and $0.4 million, which is treated as a deemed contribution in the consolidated statements of equity and mezzanine equity and as a deemed distribution for purposes of determining net income per common unit. During the year ended December 31, 2018, we paid $0.4 million of incentive distribution rights.

Due from Affiliates

At December 31, 2020 and 2019, the General Partner and affiliates owed $1.3 million and $1.1 million, respectively, to the Partnership primarily for current quarter general and administrative reimbursement, unconsolidated JV management fees and for rents received on our behalf, offset by rents received on behalf of the unconsolidated JV.

17. Segment Information

Prior to June 30, 2020, the Partnership had the following three reportable segments: (i) wireless communication, (ii) outdoor advertising, and (iii) renewable power generation. Prior period amounts have been revised to reflect classification of the European outdoor advertising portfolio as a discontinued operation and presentation of the assets of the European outdoor advertising portfolio as assets held for sale. Consequently, an evaluation of segment reporting thresholds resulted in changes in our segment presentation for all prior periods presented. As of June 30, 2020, the Partnership had the following four reportable segments: (i) wireless communication, (ii) digital infrastructure, (iii) outdoor advertising and (iv) renewable power generation for all periods presented.

The Partnership’s wireless communication segment consists of leasing infrastructure and real property interests and providing financing to companies in the wireless communication industry in the United States, Canada, and Australia. The Partnership’s outdoor advertising segment consists of leasing real property interests to companies in the outdoor advertising industry in the United States, Canada and Australia. The Partnership’s renewable power generation segment consists of leasing real property interests and providing financing to companies in the renewable power industry in the United States. The Partnership’s digital infrastructure segment consists of leasing real property interests to companies in the digital infrastructure industry in the United States and Canada. Items that are not included in any of the reportable segments are included in the corporate category.

The reportable segments are strategic business units that offer different products and services. They are commonly managed as all four businesses require similar marketing and business strategies. Because our tenant lease arrangements are mostly triple net or effectively triple net, we evaluate our segments based on revenue. We believe this measure provides investors relevant and useful information because it is presented on an unlevered basis.

18. Commitments and Contingencies

The Partnership’s commitments and contingencies include customary claims and obligations incurred in the normal course of business. In the opinion of management, these matters will not have a material effect on the Partnership’s combined financial position.

There has been consolidation in the wireless communication industry historically that has led to certain lease terminations. The past consolidation in the wireless industry has led to rationalization of wireless networks and reduced demand for tenant sites. On April 1, 2020, T-Mobile and Sprint completed their merger. Significant consolidation among our tenants in the wireless communication industry (or our tenants’ sub‑lessees) may result in the decommissioning of certain existing communications sites, because certain portions of these tenants’ (or their sub‑lessees’) networks may be redundant. The impact of any future consolidation in the wireless communication industry and the termination of additional leases in our portfolio would result in lower rental revenue and may lead to impairment of our real property interests or other adverse effects to our business.

As of December 31, 2020, the Partnership had approximately $63.5 million of real property interests subject to subordination to lenders of the underlying property. To the extent a lender forecloses on a property the Partnership would take impairment charges for the book value of the asset and no longer be entitled to the revenue associated with the asset.

Substantially all of our tenant sites are leased to tenants under triple net or effectively triple-net lease arrangements, which require the tenant or the underlying property owner to pay all utilities, property taxes, insurance and repair and maintenance costs. Our overall financial results could be impacted to the extent the owners of the fee interest in the real property or our tenants do not satisfy their obligations.

19. Tenant Concentration

For the years ended December 31, 2020, 2019 and 2018, the Partnership had the following tenant revenue concentrations. Prior period concentrations have been revised to exclude discontinued operations:

	Year Ended December 31,
Tenant	2020			2019			2018
T-Mobile		14.0	%		15.6	%		18.3	%
Clear Channel Outdoor		10.6	%		13.5	%		11.8	%

Most tenants are subsidiaries of these companies but have been aggregated for purposes of showing revenue concentration. Financial information for these companies can be found at www.sec.gov.

The loss of any one of our large customers as a result of consolidation, merger, bankruptcy, insolvency, network sharing, roaming, joint development, resale agreements by our customers or otherwise may result in (1) a material decrease in our revenue, (2) uncollectible account receivables, (3) an impairment of our deferred site rental receivables, wireless infrastructure assets, site rental contracts or customer relationships intangible assets, or (4) other adverse effects to our business.

20. Income Taxes

The Partnership is not a taxable entity for United States federal income tax purposes instead any tax liability on our net income is generally borne by our partners through their allocation of taxable income. The Partnership files in various state jurisdictions that generally follow this federal treatment.

Our consolidated corporate U.S. subsidiary Asset OpCo conducts certain activities that may not generate qualifying REIT income and is therefore taxable as a corporation for U.S. federal and state income tax purposes. Additionally, certain consolidated corporate foreign subsidiaries of the Partnership are subject to income tax in the foreign jurisdictions where they operate. 

The following information pertains to the Partnership’s income taxes on a consolidated basis.

Consolidated Partnership income before income tax expense by geographic area is as follows (in thousands):

The statutory federal income tax rate is 21 percent for the years ended December 31, 2020, 2019 and 2018 and the foreign income tax rates range from 15 percent to 39 percent. The difference between income tax expense (benefit) recorded by us and income taxes computed by applying the statutory corporate income tax rates to the consolidated Partnership income before income tax expense (benefit) is due to the fact that the majority of our income is not subject to federal, state and foreign income tax as described above.

Reconciliation between the U.S. statutory rate and the effective rate from income from continuing operations before income tax expense (benefit) is as follows:

	Year Ended December 31,
	2020			2019			2018
Statutory tax rate		21	%		21	%		21	%
Adjustment to reflect MLP/REIT status		(21	)%		(10	)%		(21	)%
Foreign taxes		(3	)%		1	%		—	%
Valuation allowance		1	%		—	%		—	%
Change in tax law		—	%		—	%		—	%
Other		(2	)%		1	%		—	%
Effective tax rate		(4	)%		13	%		—	%

Deferred income taxes are recorded based on temporary differences between the financial statement carrying amounts and the tax basis of assets and liabilities. The statutory federal income tax rate of 21 percent is used for valuation of the deferred tax assets and liabilities and is based upon the tax rate expected to be in place when the deferred tax assets and liabilities are recognized. Asset OpCo and the corporate foreign subsidiaries routinely assesses their ability to realize deferred tax assets. If an entity concludes that it is more likely than not that some or all of the deferred tax assets will not be realized, the tax asset is reduced by a valuation allowance. As of December 31, 2020, the Partnership has a valuation allowance of $0.1 million and believes it is more likely than not that its other deferred tax assets recorded will be realized.

The consolidated domestic and foreign deferred tax asset was $2.8 million and $2.3 million for the years ended December 31, 2020 and 2019, respectively. The increase in the deferred tax asset in the current year is due to an increase in the state tax rate and generated net operating losses.  

As of December 31, 2020, we had an immaterial liability for unrecognized tax benefits. We did not have any significant interest and penalties related to income taxes during the year ended December 31, 2020.

The Partnership had domestic and foreign NOLs for the year ended December 31, 2020, which can be used to offset taxable income in future and prior years, subject to specified limitations. As of December 31, 2020, Asset OpCo and foreign subsidiaries had an NOL carryforward of $2.3 million translating to a deferred tax asset before valuation allowance of $0.5 million and a valuation allowance of $0.1 million. As of December 31, 2018, Asset OpCo had an NOL carryforward of $0.4 million, translating to a deferred tax asset before valuation allowance of less than $0.1 million. In 2019, Asset OpCo fully utilized existing NOL carryforwards.

2. Basis of Presentation and Summary of Significant Accounting Policies

Basis of Presentation and Principles of Consolidated Financial Statements

During the year ended December 31, 2018, the Partnership completed one drop-down acquisition of 127 tenant sites and related real property interests from the Sponsor and affiliates in exchange for total consideration of $59.9 million (the “Drop-down Acquisitions” or “Drop-down Assets”). There were no Drop-down Acquisitions during the years ended December 31, 2020 and 2019. Drop-down Acquisitions from the Sponsor and affiliates are accounted for prospectively as transfers of net assets in the period in which the transfer occurs at the net carrying value. Any differences between the cash consideration and the net carrying value of the transfer of net assets is allocated to the General Partner.  

On an ongoing basis, we evaluate each legal entity that is not wholly owned by us in accordance with the consolidation guidance. The accompanying consolidated financial statements include the accounts of the Partnership, its wholly-owned subsidiaries and those entities in which it has a controlling interest. Investments in entities that the Partnership does not control are accounted for using the equity or cost method, depending upon the Partnership’s ability to exercise significant influence over operating and financial policies.

The consolidated financial statements were prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). All intercompany transactions and account balances have been eliminated. Management believes that the assumptions and estimates used in the preparation of the underlying consolidated financial statements are reasonable. However, the consolidated financial statements herein do not necessarily reflect what the Partnership’s financial position, results of operations, comprehensive income or cash flows would have been if the Partnership had been a stand-alone entity during the periods presented. As a result, historical financial information is not necessarily indicative of the Partnership’s future results of operations, comprehensive income, financial position or cash flows. All references to tenant sites are unaudited.

Use of Estimates

The preparation of the consolidated financial statements, in conformity with GAAP, requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.

Purchase Accounting for Acquisitions

The Partnership applies the asset acquisition method to all acquired investments of real property interests for transactions that meet the definition of an asset acquisition based on the revised framework for determining whether an integrated set of assets meets the definition of a business. The purchase consideration for the real property interests is allocated to the acquired tangible assets, such as land and building, and the identified intangible assets and liabilities, consisting of the value of perpetual and limited life easements, above-market and below-market leases and in-place leases, based in each case on their fair values. The fair value of the assets acquired and liabilities assumed is typically determined by using the discounted cash flow valuation method using discount rates ranging between 6% and 20% with a weighted average discount rate of 8.5%. In certain instances, such as data center acquisitions, the sales comparison approach is used to determine the fair value of the land assets, the cost approach to determine the fair value of the building and site improvements, and the income approach to determine the fair value of the real property interest and liability assumed. When determining the fair value of intangible assets acquired, the Partnership estimates the applicable discount rate and the timing and amount of future cash flows. Transaction costs related to asset acquisitions are capitalized.

Factors considered in estimating the fair value of tangible and intangible assets acquired include information obtained about each asset as a result of Landmark’s pre-acquisition due diligence and its marketing and leasing activities. In order to calculate the estimated in-place lease value, we employed the income approach in accordance with ASC 805 by multiplying the anticipated market absorption period by the market rent at the time of acquisition for each in-place lease agreement. Based on our experience in the industry, we have determined a range of lease execution timelines to be between one and twelve months. For the in-place lease valuation, we consider a lease-up period of four to eight months to be representative of the market.

We estimated the fair value of real property interests using the income approach. The discount rates used ranged from 6% to 20% with a weighted average discount rate of 8.5%. In certain instances, such as data center acquisitions, the sales comparison approach is used to determine the fair value of the land assets, the cost approach to determine the fair value of the building and site improvements, and the income approach to determine the fair value of the real property interest and liability assumed. The value of tenant relationships has not been separated from in-place tenant lease value for the real estate acquired as such value and its consequence to amortization expense is materially consistent with the in-place tenant lease value for these particular acquisitions. Should future acquisitions of real property interests result in allocating material amounts to the value of tenant relationships, an amount would be separately allocated and amortized over the estimated life of the relationship. The value of in-place leases and customer relationship is amortized to expense over the estimated period the tenant is expected to be leasing the site under the existing terms which typically range from 2 to 20 years. If a tenant lease were to be terminated prior to its stated expiration, all unamortized amounts relating to that lease would be impaired.

The discount rate associated with each asset varies based on the location of an asset (including demographics and zoning restrictions), and other asset specific characteristics. Market rent for each asset is determined based on location of each asset, asset type, zoning restrictions, ground space necessary for the tenant’s equipment, remaining site capacity, visibility (specifically for billboards), and nearby sites.

In allocating the purchase consideration of the identified intangible assets and liabilities of an acquired asset, above-market, below-market and in-place lease values are calculated based on the present value (using a discount rate that reflects the risks associated with the leases acquired) of the difference between (i) the contractual amounts to be paid pursuant to the in-place leases and (ii) management’s estimate of fair market lease rates for the corresponding in-place leases measured over the estimated period the tenant is expected to be leasing the site under the above or below-market terms. The capitalized above-market and below-market lease values are amortized as a decrease or increase, respectively, to rental income over the estimated period the tenant is expected to be leasing the site. Wireless communication and outdoor advertising tenant leases obtained by the Partnership through its acquisition of real property interests are generally cancellable, upon 30 to 180 days’ notice by the tenants, with no significant penalty. Digital infrastructure and renewable power generation tenant leases are generally non-cancellable. With respect to below-market leases, consideration is given to any below-market renewal periods. However, for wireless communication assets, we estimated the above/below-market lease value over an analysis period of the earlier of the lease expiration or 10 years based on estimated useful life of the underlying equipment and assets. For outdoor advertising assets, we estimated the above- or below-market lease value over an analysis period of the earlier of the lease expiration or 20 years, based on a longer estimated useful life of 20 years for billboards.

Real Property Interests and Depreciation and Amortization

Real property interests consist primarily of land, easements and lease assignments underlying wireless communication, digital infrastructure, outdoor advertising and renewable power generation. The real property interests are typically held as ownership of land or easements to use land, or roof tops, both of which allow us to use the asset for a specific purpose. Real property interests, excluding land, are intangibles that are recorded at cost. Amortization is computed using the straight-line method over the estimated useful lives of the real property interests, which is estimated as the shorter of the revenue generating period of the asset or the term of the real estate rights which range from 12 to 99 years. Depreciation of buildings, site improvements or equipment is computed using the straight-line method over the assets’ estimated useful lives. Real property interests with a perpetual term are not amortized but evaluated periodically for impairment.

The Partnership assesses whether there has been an impairment in the value of long-lived assets whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount to the future estimated net cash flows, undiscounted and without interest, expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the estimated fair value of the assets based upon what a market participant would be willing to pay for the real estate interest. The estimated fair value of the asset group identified for step two testing is based on either Level 3 inputs utilizing the income approach with a market discount rate and estimated cash flows, or Level 2 inputs based upon the sales comparison approach to a similar asset. Assets to be disposed of are reported at the lower of the carrying amount or fair value, less costs to sell utilizing the Level 3 and Level 2 inputs discussed below.

Concurrent with the Partnership’s adoption of ASU No. 2016-02 on January 1, 2019, the Partnership has elected to recognize expense associated with short-term leases (those with a non-cancellable lease term of 12 months or less) under which the Partnership is the lessee on a straight-line basis and not recognize those leases on its consolidated balance sheets. For leases other than short-term operating and finance leases under which the Partnership is the lessee, such as ground leases, the Partnership recognizes a right-of-use asset and related lease liability on its consolidated balance sheet at inception of the lease based on the present value of the remaining minimum rental payments using each respective lease term and a corresponding incremental borrowing rate. Operating lease assets are included in right of use, net and finance lease assets are included in real property interests in the consolidated balance sheets.

Development Operations

The Partnership capitalizes direct construction and development costs, including pre-development costs, interest, and other costs directly related and essential to the development or construction of an asset. The Partnership capitalizes construction and development costs while substantive activities are ongoing to prepare an asset for its intended use. Fluctuations in our development, pre-construction, and construction activities could result in significant changes to expenses and net income. Costs incurred after a project is substantially complete and ready for its intended use are expensed as incurred. Should development, pre-construction, or construction activity cease, interest and certain other costs would no longer be eligible for capitalization and would be expensed as incurred. Expenditures for repairs and maintenance are expensed as incurred. The Partnership computes depreciation on assets placed in service and improvements using the straight-line method over the assets’ estimated useful lives.

Development projects and other similar contracts are assessed to determine whether it continues to meet our investment return standards. Assessments are made separately for each project on a quarterly basis and are affected by the following factors relative to the market in which the asset is located, among others: estimated development and construction costs and projected profitability. When a decision is made to cease construction on certain projects due to market conditions and/or fluctuations in our development strategy, we write off the related capitalized costs, including pre-construction costs. During the year ended December 31, 2019, the Partnership ceased construction on a certain development project and recognized impairment charges of $1.6 million including a write off of $0.1 million in capitalized interest.

Fair Value of Financial Instruments

The standard establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable input be used when available. Observable inputs are inputs that the market participants would use in pricing an asset or liability developed based on market data obtained from sources independent of the Partnership. Unobservable inputs are inputs that reflect the Partnership’s assumptions about what market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. The hierarchy is measured in three levels based on the reliability of inputs:

Level 1 – unadjusted quoted prices in active markets that are accessible at the measurement date for identical assets or liabilities.

Level 2 – quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-derived valuations in which significant inputs and significant value drivers are observable in active markets; and,

Level 3 – prices or valuations derived from other valuation methodologies where little or no market data is available that requires inputs that are both significant to the fair value measurement and unobservable, including pricing models, discounted cash flow models and similar techniques.

Cash and Cash Equivalents

All highly liquid investments with a maturity of three months or less when purchased are considered to be cash and cash equivalents. The Partnership monitors the cash balances in its operating accounts and adjusts the cash balances as appropriate; however, these cash balances could be impacted if the underlying financial institutions fail or are subject to other adverse conditions in the financial markets. To date, the Partnership has experienced no loss or lack of access to cash in the operating accounts.

Restricted Cash

Restricted cash primarily consists of amounts pledged as collateral to secure obligations. As of December 31, 2020 and 2019, the amount of restricted cash was $3.2 million and $5.6 million. See Note 10, Debt for additional information.

Accounting for Derivative Financial Instruments and Hedging Activities

The Partnership utilizes interest rate swap contracts to manage interest costs and risks associated with changing interest rates. These derivative financial instruments are carried at fair value on the consolidated balance sheets, with the change in such fair value being recorded through earnings as an unrealized gain or loss in the consolidated statements of operations.

Investments in Receivables, Net

The Partnership acquired streams of future cash flows associated with real property interests and certain lease arrangements that meet the definition of a financial asset within the wireless communication, outdoor advertising and renewable power generation industries. For certain investments in receivables, the Partnership has no significant rights or obligations associated with the cash flows other than in certain arrangements, to pass a portion of the cash flows received to the owner of the respective lease. Additionally, certain lease arrangements of real property interests meet the definition of a financial asset and are included in investments in receivables in our financial statements. The future cash flow streams are recorded at their net present value based on the estimated net cash flows to be received by the Partnership using the implied discount rate at the date of the acquisition.

Receivables are classified as held-for-investment based on management’s intent and ability to hold the receivables for the foreseeable future or to maturity. Receivables held-for-investment are carried at amortized cost and are reduced by a valuation allowance for estimated credit losses as necessary. Interest on receivables is accreted to income over the life of the receivables using the interest method. The interest method is applied on an individual receivable basis when collectability of the future payments, when due in accordance with the contractual terms of the arrangement, is reasonably assured. Receivables are transferred from held-for-investment to held-for-sale when management no longer intends to hold the receivables for the foreseeable future. Receivables held-for-sale are recorded at the lower of cost or fair value.

As of January 1, 2020, the Partnership revised its measurement of impairment for investment in receivables measured at amortized cost from an incurred loss methodology to an expected loss methodology, in accordance with the adoption of ASU No. 2018-19, Codification Improvements to Topic 326, Financial Instruments – Credit Losses. The measurement of expected credit losses under the current expected credit loss model is based on relevant information including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amounts. As a result, the Partnership recognized $0.1 million as a cumulative adjustment to retained earnings and as a reduction to investment in receivables.

Prior to January 1, 2020, receivables were placed on non-accrual status when management determined that the collectability of contractual amounts were not reasonably assured. While on non-accrual status, receivables were either accounted for on a cash basis, in which income is recognized only upon receipt of cash, or on a cost-recovery basis, where cash receipts reduced the carrying value of the receivable, based on management’s expectation of future collectability. Allowances were established for receivables based upon an estimate of probable losses on an individual receivable by receivable basis if they were determined to be impaired. Receivables were impaired when it was deemed probable that the Partnership would be unable to collect all amounts when due in accordance with the contractual terms of the loan. An allowance is based upon the Partnership’s assessment of the borrower’s overall financial condition, economic resources, payment record, the prospects for support from any financially responsible guarantors and, if appropriate, the net realizable value of any collateral. These estimates consider all available evidence including the expected future cash flows discounted at the receivable’s effective interest rate, fair value of collateral, general economic conditions and trends, historical and industry loss experience and other relevant factors, as appropriate.

In 2018 and 2019, the Partnership assessed investments in receivables for impairment. Internally generated cash flow projections were used to determine if the receivables were expected to be repaid in accordance with the terms of the related agreements. If it was probable that a receivable would not be repaid in accordance with the related agreement, the receivable was deemed impaired. To measure impairment, the present value of the expected future cash flows discounted was calculated using the original effective interest rate. If the present value was less than the carrying value of the receivable, a specific impairment reserve is recorded for the difference. For the year ended December 31, 2018, the Partnership impaired 16 of its investments in receivables and recognized impairment charges totaling $0.8 million. The investments in receivables were impaired to their net realizable value. There was no impairment of investments in receivables during the year ended December 31, 2019.

Investment in Unconsolidated Joint Venture

The Partnership accounts for its investment in an unconsolidated joint venture using the equity method of accounting. Under the equity method, the investment is initially recorded at fair value and subsequently adjusted for distributions and the Partnership’s proportionate share of equity in the joint venture’s income (loss). The Partnership recognizes its proportionate share of the ongoing income or loss of the unconsolidated joint venture as equity income (loss) from unconsolidated joint venture on the consolidated statements of operations. On a quarterly basis, the Partnership evaluates its investment in an unconsolidated joint venture for other-than-temporary impairments. The Partnership elected as an accounting policy to reflect unconsolidated joint venture distributions in the consolidated statements of cash flows using the nature of the distribution approach. Accordingly, the net proceeds were classified as return on investment in unconsolidated joint venture within the operating activities section of the consolidated statements of cash flows for the year ended December 31, 2020 and 2019.

Discontinued Operations

If the disposition of a component, being an operating or reportable segment, business unit, subsidiary or asset group, represents a strategic shift that has or will have a major effect on the Partnership’s operations and financial results, the operating profits or losses of the component disposed of by sale or when classified as held for sale, and the gain or loss upon disposition of the component, are presented as discontinued operations in the statements of operations.

On June 17, 2020, the Partnership completed the sale of its interest in the consolidated joint venture that holds its European outdoor advertising portfolio for a purchase price of £95 million. As a result, the sale of the European outdoor advertising portfolio represents a strategic shift that will have a major effect on the Partnership’s operations and financial results and has met the criteria as discontinued operations in June 2020. Accordingly, for all prior periods presented, the related assets and liabilities, including borrowings under the revolving credit facility and an interest rate swap agreement denominated in British pound sterling (“GBP”), are presented as assets and liabilities held for sale on the consolidated balance sheets (Note 4) and the related operating results, including interest expense and unrealized loss on the interest rate swap agreement denominated in GBP, are presented as income from discontinued operations on the consolidated statement of operations (Note 9).

Deferred Loan Costs

Costs incurred associated with the revolving credit facility are capitalized as deferred loan costs and are included in deferred loan costs, net in the consolidated balance sheets in accordance with ASU 2015-15, Interest – Imputation of Interest (Subtopic 835-30): Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements. Costs incurred in obtaining the secured debt facilities are deducted from the carrying amount of the debt liabilities and deferred loan costs are amortized to interest expense over the life of the related loan. When facilities are amended and restated that result in an of extinguishment of debt, any unamortized deferred loan costs, as well as charges incurred for the termination, are recorded to interest expense in the period of the amendment and restatement.

Revenue Recognition

The Partnership recognizes rental income under operating leases, including rental abatements, lease incentives and contractual fixed increases, if any, from tenants under lease arrangements with minimum fixed and determinable increases on a straight-line basis over the non-cancellable term of the related leases when collectability is reasonably assured. The excess of rents recognized over amounts contractually due pursuant to the underlying leases are recorded as deferred rent assets. The excess of rent payments collected over amounts recognized contractually due pursuant to the underlying lease are recorded as prepaid rents. The Partnership accounts for and presents tenant reimbursements as a component of rental revenue in our consolidated income statements in accordance with the new lease standard (“ASC 842”). Tenant reimbursements are recognized as revenue in the period during which the applicable expenses are incurred and the tenant’s obligation to reimburse us arises.

For the years ended December 31, 2020, 2019, and 2018, leases obtained by the Partnership through its acquisition and ownership of real property interests in the wireless communication industry and the outdoor advertising industry were generally cancelable upon 30 - 180 days’ notice by the tenants with no significant penalty. The Partnership evaluates whether the lease arrangements economically compel the tenant to not cancel the lease in determining the term of the lease by considering various factors such as cancellation rights, availability of alternative sites, and historical cancellation rates. For cancellable leases where the tenant is not economically compelled to continue the lease, the term of the lease is considered to be the non-cancellable period with rental abatements and contractual fixed rate increases recorded in the period the amounts become due and payable. Leases obtained through development projects, are generally non‑cancellable for the initial term.

• Wireless Communication – As a result of various factors, including the cancellation rights, ability to find alternative sites, credit risk, and historical cancellation and lease amendment rates, the lease term is generally considered to be the non-cancellable term of the lease of 30 to 180 days. For these leases, rental abatements and contractual fixed increases are recorded in the period the amounts become due and payable.

• Digital Infrastructure – The lease term is generally non-cancellable.

• Outdoor Advertising and Renewable Power Generation – The lease term is generally considered to be the non-cancellable term of the remaining portion of the existing term of the lease.

The capitalized above-market and below-market lease values are amortized as a decrease or increase, respectively, to rental income over the estimated period the tenant is expected to be leasing the site.

Certain leases provide for the greater of a minimum rent or a percentage of the revenue generated by the tenant (“Contingent Rent”). Contingent Rent is recognized when measurable and all possible contingencies have been eliminated. During the years ended December 31, 2020, 2019, and 2018, the Partnership recognized $1.4 million, $1.6 million and $1.2 million of Contingent Rent, respectively.

Rents Receivable, net

Rents receivables consists of tenant receivables arising in the normal course of business. Tenant receivables are uncollateralized customer obligations requiring payment within various time frames not to exceed one year from the invoice date. If the Partnership determines that collectability of lease payments is not probable, the rent receivable balance is written off and recognized as a decrease in revenue in that period and future revenue recognition is limited to amounts contractually owed and paid.

Income Taxes

The Partnership is generally not subject to federal, state or local income taxes, except for our subsidiary Landmark Infrastructure Asset OpCo LLC (“Asset OpCo”) and our foreign subsidiaries. Each limited partner is responsible for the tax liability, if any, related to its proportionate share of the Partnerships’ taxable income or loss. Asset OpCo conducts certain activities that may not generate qualifying income and will be treated as a corporation for U.S. federal income tax purposes. Asset OpCo and certain consolidated foreign subsidiaries of the Partnership conduct certain activities in international locations that generate taxable income and will be treated as taxable entities. Additionally, our consolidated REIT subsidiary, Landmark Infrastructure Inc., a Delaware corporation, files as a corporation for U.S. federal income tax purposes. The REIT Subsidiary has elected to be treated as a REIT and we believe that it has operated in a manner that has allowed the REIT Subsidiary to qualify as a REIT for federal income tax purposes, and the REIT Subsidiary intends to continue operating in such manner. If the REIT Subsidiary fails to qualify as a REIT in any taxable year, and is unable to avail itself of certain savings provisions, all of its taxable income would be subject to federal income tax at regular corporate rates. The Partnership may also be subject to various non-income taxes, filing fees, and franchise taxes in various states that are reflected in operating expenses. The Partnership follows the requirements of ASC Topic 740, Income Taxes (“ASC 740”), relating to uncertain tax positions. Based on its evaluation under ASC 740, the Partnership has concluded that there are no significant uncertain tax positions requiring recognition in the consolidated financial statements, nor has the Partnership been assessed interest or penalties by any major tax jurisdictions.

Foreign Currency Translation

Assets and liabilities denominated in foreign currencies that are translated into U.S. dollars use exchange rates in effect at the end of the period, and revenues and expenses denominated in foreign currencies that are translated into U.S. dollars use average rates of exchange in effect during the related period. Gains and losses resulting from translation adjustments are included in accumulated other comprehensive income (loss).

Foreign Currency Transactions

Transactions denominated in a currency other than U.S. dollars are recorded upon initial recognition at the exchange rate on the date of the transaction. After initial recognition, monetary assets and liabilities denominated in a foreign currency are remeasured at each reporting date into the functional currency at the exchange rate on that date. For all periods presented, the foreign currency interest rate swap agreement and a debt agreement that resulted in mark to market foreign currency transaction adjustments were reclassified to discontinued operations.  

Risk Management

The Partnership is subject to risks incidental to the ownership and investment in real property interests. These risks and uncertainties include the competitive environment in which the Partnership operates – local, regional, and national economic conditions, including consumer confidence, employment rates, and the availability of capital; uncertainties and fluctuations in capital and securities markets; the cyclical and competitive nature of the real estate industry; changes in tax laws and their interpretation; legal proceedings; effect of restrictive covenants in the loan agreements; and the effects of governmental regulation.

In the normal course of business, the Partnership encounters economic risk, including interest rate risk, currency risk, credit risk, and market risk. Interest rate risk is the result of movements in the underlying variable component of financing rates. Credit risk is the risk of default that results from an underlying tenant/borrower’s inability or unwillingness to make contractually required payments. Market risk reflects changes in the valuation of real property interests and investments in receivables held by the Partnership.

Concentration of Credit Risk

The Partnership’s credit risk relates primarily to rent receivables, investments in receivables, cash and interest rate swap agreements. Cash accounts at each U.S. institution are insured by the Federal Deposit Insurance Corporation up to $250,000. The Partnership has not experienced any losses to date on invested cash.

Credit risk associated with interest rate swap agreements arises from the potential failure of counterparties to perform in accordance with the terms of their contracts. The Partnership’s risk management policies define parameters of acceptable market risk and limit exposure to credit risk. Credit exposure resulting from derivative financial instruments is considered in their fair value amounts, among other factors such as the potential adverse position exposure arising from changes over time in interest rates, maturities, and other relevant factors. The Partnership does not anticipate nonperformance by any of its counterparties.

The Partnership’s real property interests are primarily located throughout the United States. The ability of the tenants to honor the terms of their respective leases is dependent upon the economic, regulatory, and social factors affecting the communities in which the tenants operate. In certain instances, the Partnership’s position in the real property interest may be subordinate to a mortgage lender on the real property.

Business Segments

The Financial Accounting Standards Board (“FASB”) accounting guidance with regard to disclosures about segments of an enterprise and related information establishes standards for the manner in which public business enterprises report information about operating segments. The Partnership has four reportable segments, wireless communication, digital infrastructure, outdoor advertising and renewable power generation for all periods presented.

Recently Issued Accounting Standards

Changes to GAAP are established by the FASB in the form of Accounting Standards Updates (“ASUs”) to the FASB’s Accounting Standard Codification. The Partnership considers the applicability and impact of all ASUs. Newly issued ASUs not listed below are expected to not have any material impact on its combined financial position and results of operations because either the ASU is not applicable or the impact is expected to be immaterial.

In April 2020, the FASB issued a question and answer document (the “Lease Modification Q&A”) focused on the application of lease accounting guidance to lease concessions provided as a result of the COVID-19 pandemic. Under existing GAAP, the Partnership would have to determine, on a lease by lease basis, if a lease concession was the result of a new arrangement reached with the tenant (treated within the lease modification accounting framework) or if a lease concession was under the enforceable rights and obligations within the existing lease agreement (precluded from applying the lease modification accounting framework). The Lease Modification Q&A allows the Partnership, if certain criteria have been met, to bypass the lease by lease analysis, and instead elect to either apply the lease modification accounting framework or not, with such election applied consistently to leases with similar characteristics and similar circumstances. The Partnership has elected to apply such relief and will avail itself of the election to avoid performing a lease by lease analysis and not apply the lease modification accounting framework. The Lease Modification Q&A had no material impact on the Partnership’s consolidated financial statements.

In June 2016, the FASB issued ASU No. 2016-13, Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), which establishes ASC 326, Financial Instruments – Credit Losses. The ASU revises the measurement of impairment for certain financial instruments measured at amortized cost from an incurred loss methodology to an expected loss methodology. The ASU affects trade receivables, debt securities, net investment in leases, and most other financial assets that represent a right to receive cash. This update is effective for annual and interim financial statement periods beginning after December 15, 2019, with early adoption permitted for financial statement periods beginning after December 15, 2018. In November 2018, the FASB issued ASU No. 2018-19, Codification Improvements to Topic 326, Financial Instruments – Credit Losses. This ASU clarifies that receivables from operating leases are accounted for using the lease guidance and not as financial instruments. The measurement of expected credit losses under the current expected credit loss model is based on relevant information including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amounts. The Partnership adopted the guidance as of January 1, 2020 and recognized $0.1 million as a cumulative adjustment to retained earnings and as a reduction to investments in receivables as of the effective date.

3. Acquisitions and Developments

Drop-down Acquisitions

During the year ended December 31, 2018, the Partnership completed one Drop-down Acquisition from our Sponsor and affiliates. There were no drop-down acquisitions during the years ended December 31, 2020 and 2019. Certain real property interests and financing assets included in the Drop-down Acquisitions completed by the Partnership were part of the right of first offer assets acquired from Landmark Dividend Growth Fund-H LLC (“Fund H”). All other Drop-down Acquisitions have been made directly from our Sponsor or from a wholly owned subsidiary of our Sponsor. The following table presents the Drop-down Acquisitions completed by the Partnership:

		Number of Tenant Sites								Consideration (in millions)
						Renewable				Borrowings
		Wireless		Outdoor		Power				and Available		Common
Acquisition Date	Source	Communication		Advertising		Generation		Total		Cash		Units		Total
January 18, 2018	Fund H		30		90		7		127	$	32.6	$	27.3	$	59.9
2018 Acquisitions			30		90		7		127	$	32.6	$	27.3	$	59.9

Drop-down Acquisitions are accounted for as transfers of net assets between entities under common control. The transfer of net assets is accounted for prospectively in the period in which the transfer occurs at the net carrying value. Any differences between the cash consideration and the net carrying value of the transfer of net assets have been allocated to the General Partner.

Third Party Acquisitions

During the years ended December 31, 2020, 2019 and 2018, the Partnership completed various direct third-party acquisitions. Third-party acquisitions include acquisitions in exchange for Common Units pursuant to our previously filed and effective registration statement on Form

S-4, in which we may offer and issue, from time to time, an aggregate of up to 5,000,000 Common Units in connection with the acquisition by us or our subsidiaries of other businesses, assets or securities (the “Unit Exchange Program” or “UEP”).

The following table presents direct third-party acquisitions, excluding transaction costs, completed by the Partnership during the years ended December 31, 2020, 2019 and 2018:

Leases

The Partnership evaluates whether an easement meets the definition of a lease under the new lease standard (“ASC 842”). The Partnership determines if an arrangement is a lease at the date of acquisition. The Partnership considers an arrangement to be a lease if it conveys the right to control the use of the leased site or ground space underneath a leased site for a period of time in exchange for consideration. While most of our leases are classified as operating leases in which the Partnership is the lessor, the Partnership is the lessee in an insignificant population of operating and finance leases that have recurring ground lease rental payments. The lease liability is the present value of the remaining minimum rental payments using each respective lease term and a corresponding incremental borrowing rate. We use a weighted-average discount rate of approximately 4.3%, which is the interest rate that we estimate we would have to pay to borrow on a collateralized basis over a similar term for an amount equal to the lease payments. As of December 31, 2020, the weighted-average remaining lease term of operating leases is approximately 8 years. Operating lease assets are included in right of use, net and finance lease assets are included in real property interests in the Consolidated Balance Sheets.

The following table illustrates information about other lease related balances as of December 31, 2020 and 2019 (in thousands):

	December 31,

Developments

During 2017, the Partnership started developing an ecosystem of technologies that provide smart enabled infrastructure including stealth towers and digital outdoor advertising kiosks across North America. Stealth towers are self-contained, neutral-host towers designed for wireless carrier and other wireless operator collocation. The stealth towers are designed for macro, mini macro and small cell deployments and will support Internet of Things (IoT), carrier densification needs, private LTE networks and other wireless solutions.

During the fourth quarter of fiscal year 2018, the Partnership entered into an agreement with Dallas Area Rapid Transit (“DART”) to develop a smart media and communications platform which will include the deployment of content-rich kiosks and the Partnership’s smart enabled infrastructure ecosystem solution on strategic high-traffic DART locations.

As of December 31, 2020 and 2019, the Partnership’s $44.8 million and $49.1 million, respectively, of construction in progress balance primarily related to these projects, respectively. During the years ended December 31, 2020 and 2019, the Partnership deployed two stealth towers, 112 DART kiosks and placed in service other assets for a total of $16.2 million.

Sales

On June 17, 2020, the Partnership completed the sale of its interest in the consolidated joint venture that holds its European outdoor advertising portfolio for a purchase price of £95 million. We recognized a gain on sale of real property interest of $15.5 million upon completion of the sale. The sale of the European outdoor advertising portfolio has met the criteria as discontinued operations. Accordingly, for all prior periods presented, the related assets and liabilities are presented as assets and liabilities held for sale on the consolidated balance sheets, as described below, and the related operating results and gain on sale are presented as income from discontinued operations on the consolidated statement of operations for all periods presented (Note 9).

During the year ended December 31, 2019, the Partnership completed a sale of two wireless communication sites held for sale and three outdoor advertising sites to a third party in exchange for cash consideration of $1.4 million. We recognized a gain on sale of real property interest of $0.5 million upon completion of the sale.

On June 27, 2019, the Partnership completed a sale of its real property interests and investments in receivables held for sale in its taxable subsidiary for total consideration of $31.8 million. We recognized a gain on sale of real property interests and investments in receivables of $11.7 million before income taxes, or $8.6 million after income taxes, upon completion of the sale.

On January 4, 2019, the Partnership completed the sale of its real property interest held for sale as of December 31, 2018 for total consideration of $13.5 million. We recognized a gain on sale of real property interest of $5.9 million upon completion of the sale.

During the year ended December 31, 2018, the Partnership completed a sale of one outdoor advertising site to a third party in exchange for cash consideration of $0.1 million. We recognized a loss on sale of real property interest of less than $0.1 million upon completion of the sale. Additionally, during the year ended December 31, 2018, the Partnership recognized a gain on the contribution of real property interests of $100 million in connection with the formation of an unconsolidated joint venture (the “JV”) in which 545 tenant sites were contributed to the JV by the Partnership as described in Note 8, Investment in Unconsolidated Joint Venture. The Partnership used $59.7 million of the net proceeds to repay a portion of the borrowings under the revolving credit facility. The Partnership has determined that the contribution does not meet the criteria for discontinued operations presentation as the contribution does not represent a strategic shift that will have a major effect on its operations and financial results and the Partnership has retained an interest in the assets through its interest in the unconsolidated joint venture. 

Purchase Price Allocation

The Partnership applies the asset acquisition method to all acquired investments of real property interests for transactions that meet the definition of an asset acquisition. The fair value of the assets acquired and liabilities assumed is typically determined by using Level III valuation methods. The most sensitive assumption is the discount rate used to discount the estimated cash flows from the real estate rights. For purposes of the computation of fair value assigned to the various tangible and intangible assets, the Partnership assigned discount rates ranging between 6% and 20% with a weighted average discount rate of 8.3%.

The following table summarizes final allocations for acquisitions made during the years ended December 31, 2020, 2019, and 2018 of estimated fair values of the assets acquired and liabilities assumed (in thousands).

Impairments

During the year ended December 31, 2020, the Partnership recognized impairment charges totaling $0.3 million for five of the Partnership’s real property interest that were impaired and one non-lease renewal. For the years ended December 31, 2019 and 2018, eight and six of the Partnership’s real property interests were impaired and we recognized impairment charges totaling, $0.7 million and $0.6 million, respectively. The carrying value of each real property interest was determined to have a fair value of zero. Additionally, the Partnership recognized impairment charges related to certain construction in progress of $1.6 million during the year ended December 31, 2019.

Investments in Receivables

7. Investments in Receivables

Investments in receivables includes financing arrangements and management agreements whereby we purchased the right to receive a portion of a rental payment under a contract but are not a party to the lease and do not have a real property interest. Additionally, certain lease arrangements of real property interests meet the definition of a financial asset and included in investments in receivables in our financial statements. Investments in receivables also includes arrangements with T‑Mobile whereby we purchased the right to retain a portion of a lease payment prior to passing the remainder to the property owner. The receivables are unsecured with payments collected over periods ranging from 2 to 99 years. These cash flow financing arrangements were recorded at the fair value at the acquisition date, using discount rates ranging from 7% to 14% and are accounted for as receivables in our consolidated financial statements.

During the year ended December 31, 2018, 16 of the Partnership’s investments in receivables were impaired and recognized impairment charges totaling $0.8 million. The investments in receivables were impaired to their net realizable value. Pursuant to the terms of the omnibus agreement, Landmark indemnified the Partnership for the loss related to the impairment of investments in receivables which is treated as a deemed capital contribution.    

Interest income recognized on the receivables totaled $0.5 million, $0.6 million and $1.4 million during 2020, 2019, and 2018, respectively. In connection with the sale of the European outdoor advertising portfolio on June 17, 2020, the Partnership completed the sale of an investment in receivable and recognized a gain on sale of investments in receivables in discontinued operations. Additionally, on June 27, 2019, the Partnership completed a sale of its investments in receivables held for sale as of March 31, 2019 and recognized a gain on sale of investments in receivables.

Investment in Unconsolidated Joint Venture

8. Investment in Unconsolidated Joint Venture

On September 24, 2018, the Partnership completed the formation of the unconsolidated JV. The Partnership contributed 545 tenant site assets to the unconsolidated JV that secured the Partnership’s $125.4 million Series 2018-1 secured notes (the “2018 Securitization”), in exchange for a 50.01% membership interest in the unconsolidated JV and $65.5 million in cash (the “Transaction”). The Partnership does not control the unconsolidated JV and therefore, accounts for its investment in the unconsolidated JV using the equity method of accounting prospectively upon formation of the unconsolidated JV. 

The Partnership recognized a gain on contribution of real property interests in accordance with ASC 610-20, Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets (“ASC 610-20”), which applies to sales or transfers to noncustomers of nonfinancial assets or in substance nonfinancial assets that do not meet the definition of a business. ASC 610-20 refers to the revenue recognition principles under ASU No. 2014-09. Under ASC 610-20, the Partnership determined it does not have a controlling financial interest in the entity that holds the assets and the arrangement meets the criteria to be accounted for as a contract, as such, the Partnership derecognized the assets and recognized a gain on the contribution of the real property interests when control of the underlying assets transferred to the buyer. The gain on the contribution of real property interests is included in the gain on sale of real property interests in the accompanying consolidated statements of operations.

In addition to the contribution of assets, the JV assumed the 2018 Securitization, which was completed by the Partnership on June 6, 2018. The 2018 Securitization financed certain tenant sites and related property interests owned by certain unrestricted special purpose subsidiaries of the Partnership, through the issuance of the Class C, Class D and Class F Series 2018-1 Secured Notes (the “2018 Secured Notes”), in an aggregate principal amount of $125.4 million. The net proceeds from the 2018 Securitization were primarily used to pay down the revolving credit facility by $120.5 million. The Class F notes are subordinated in right of payment to the Class D notes and the Class D notes are subordinated in right of payment to the Class C notes. The 2018 Secured Notes were issued at a discount of less than $0.1 million, which will be accreted and recognized as interest expense over the term of the secured notes. The Class C, Class D and Class F 2018 Secured Notes bear interest at a fixed note rate per annum of 3.97%, 4.70% and 5.92%, respectively.

Revolving Credit Facility

The Partnership’s revolving credit facility with Truist Bank, as administrative agent, and a syndicate of lenders will mature on November 15, 2023 and will be available for working capital, capital expenditures, permitted acquisitions and general partnership purposes, including distributions. On November 15, 2018, the Partnership completed its Third Amended and Restated Credit Facility and obtained commitments from a syndicate of banks with initial borrowing commitments of $450.0 million for five-years. Additionally, borrowings up to $75.0 million may be denominated in GBP, Euro, Australian dollar and Canadian dollar. Substantially all of our assets, excluding equity in and assets of unrestricted subsidiaries, after‑acquired real property (other than real property that is acquired from affiliate funds and is subject to a mortgage), and other customary exclusions, are pledged (or secured by mortgages), as collateral under our revolving credit facility. Our revolving credit facility contains various customary covenants and restrictive provisions.

In addition, our revolving credit facility contains customary events of default, including, but not limited to (i) event of default resulting from our failure or the failure of our restricted subsidiaries to comply with covenants and financial ratios, (ii) the occurrence of a change of control (as defined in the credit agreement), (iii) the institution of insolvency or similar proceedings against us or our restricted subsidiaries, (iv) the occurrence of a default under any other material indebtedness (as defined in the credit agreement) we or our restricted subsidiaries may have and (v) any one or more collateral documents ceasing to create a valid and perfected lien on collateral (as defined in the credit agreement). Upon the occurrence and during the continuation of an event of default, subject to the terms and conditions of the credit agreement, the lenders may declare any outstanding principal of our revolving credit facility debt, together with accrued and unpaid interest, to be immediately due and payable and may exercise the other remedies set forth or referred to in the credit agreement and the other loan documents.

Loans under the revolving credit facility bear interest at a rate equal to LIBOR related to the currency for which borrowings are denominated, plus a spread ranging from 1.75% to 2.25% (determined based on leverage levels). As of December 31, 2020, the applicable spread was 2.25%.

Additionally, under the revolving credit facility we will be subject to an annual commitment fee (determined based on leverage levels) associated with the available undrawn capacity subject to certain restrictions. As of December 31, 2020, the applicable annual commitment rate used was 0.20%.

The revolving credit facility requires monthly interest payments and the outstanding debt balance is due upon maturity on November 15, 2023. In June 2020, the Partnership used proceeds from the sale of the European outdoor advertising portfolio and available cash to repay borrowings totaling $115 million on its revolving credit facility, including the £40.5 million of GBP denominated borrowings. As of December 31, 2020, $214.2 million was outstanding. Our revolving credit facility contains various covenants and restrictive provisions that limit our ability (as well as the ability of our restricted subsidiaries) to incur or guarantee additional debt, among other things. As of December 31, 2020 there was $235.8 million of undrawn borrowing capacity (including standby letter of credit arrangements of $5.8 million), subject to compliance with various financial covenants. As of December 31, 2020 and 2019, the Partnership was in compliance with all financial covenants required under the revolving credit facility.

Secured Notes

On January 15, 2020, certain subsidiaries of the Partnership entered into a master note purchase and participation agreement (“MNPPA”) pursuant to which such subsidiaries issued and sold an initial $170 million aggregate principal amount of 3.90% series A senior secured notes in a private placement (the “2019 Secured Notes”). The 2019 Secured Notes mature on January 14, 2027 and include an interest-only initial term of three years. The net proceeds were used to repay in full the 2016 Secured Notes by $108 million and the revolving credit facility by $59 million. In connection with the issuance of the senior secured notes, the Partnership obtained a standby letter of credit arrangement totaling $3.4 million.

On April 24, 2018, the Partnership entered into a note purchase and private shelf agreement (the “Note Purchase Agreement”) pursuant to which the Partnership agreed to sell an initial $43.7 million aggregate principal amount of 4.38% senior secured notes, in a private placement (the “4.38% Senior Secured Notes”) involving a segregated pool of renewable power generation sites and related property interests. The 4.38% Senior Secured Notes are fully amortized through June 30, 2036. We used all the net proceeds of $41.0 million to repay a portion of the borrowings under our revolving credit facility. In connection with the issuance of the 4.38% Senior Secured Notes, the Partnership obtained a standby letter of credit arrangement totaling $2.4 million.

On November 30, 2017, the Partnership completed a securitization transaction (the “2017 Securitization”) involving certain outdoor advertising tenant sites and related property interests owned by certain unrestricted special purpose subsidiaries of the Partnership, through the issuance of the Series 2017-1 Secured Notes, Class A and Class B (the “2017 Secured Notes”), in an aggregate principal amount of $80.0 million. The net proceeds from the 2017 Securitization were primarily used to pay down the revolving credit facility by $54.0 million and $17.5 million held in a restricted reserve accounts, including $16.0 million into a site acquisition account to be used to acquire additional tenant sites pursuant to the Indenture. The Class B notes are subordinated in right of payment to the Class A notes. The 2017 Secured Notes were issued at a discount of $1.8 million, which will be accreted and recognized as interest expense over the term of the secured notes. The Class A and Class B 2017 Secured Notes bear interest at a fixed note rate per annum of 4.10% and 3.81%, respectively. The Partnership is required to make monthly payments of principal and interest on Class A and Class B 2017 Secured Notes based on a 30-year amortization period, commencing in January 2018. On each payment date on and after the payment date occurring in January 2018, available funds are used to repay the Class A 2017 Secured Notes in an amount sufficient to pay the Class A 2017 Secured Notes monthly amortization amount and to repay the Class B 2017 Secured Notes in an amount sufficient to pay the Class B 2017 Secured Notes monthly amortization amount on such payment date. No other payments of principal will be required to be made prior to the anticipated repayment date in November 2022.

The secured notes described above are collectively referred to as the “Secured Notes” and the tenant site assets securing the Secured Notes are collectively referred to as the “Secured Tenant Site Assets.”

The Secured Notes are secured by (1) mortgages and deeds of trust on substantially all of the Secured Tenant Site Assets and their operating cash flows, (2) a security interest in substantially all of the personal property of the obligors (as defined in the applicable indenture), and (3) the rights of the obligors under a management agreement. Under the terms of the applicable indenture, amounts due under the Secured Notes will be paid solely from the cash flows generated from the operation of the Secured Tenant Site Assets, as applicable, which must be deposited into reserve accounts, and thereafter distributed solely pursuant to the terms of the applicable indenture. On a monthly basis, after payment of all required amounts under the applicable indenture, subject to the conditions described below, the excess cash flows generated from the operation of such assets are released to the Partnership. As of December 31, 2020 and 2019, $3.2 million and $5.6 million was held in such reserve accounts which are classified as Restricted Cash on the accompanying consolidated balance sheets.

Certain information with respect to the 2019 and 2017 Securitization is set forth below. The debt service coverage ratio (“DSCR”) is generally calculated as the ratio of annualized net cash flow (as defined in the applicable indenture) to the amount of interest, servicing fees and trustee fees required to be paid over the succeeding 12 months on the principal amount of the Secured Notes, as applicable, that will be outstanding on the payment date following such date of determination.

			Conditions Limiting Distributions of Excess Cash
	Issuer or Borrower	Notes Issued	Cash Trap DSCR	Amortization Period
2019 Securitization	LMRK Issuer Co. LLC, 2019-1 TRS LLC	Series A Senior Secured Notes	1.30x (1)	(1)
2017 Securitization	LMRK Issuer Co. 2 LLC	Series 2017-1 Secured Notes, Class A and Class B	1.30x (2)	(3)

(1) An amortization period will commence (at the option of the related noteholder) if the debt service coverage ratio (measured for the most recently ended period of 12 consecutive months) falls below 1.30 to 1.00 on such calculation date. During an amortization period, excess cash flow will be applied to repay the applicable notes.

(2) Once triggered, a Cash Trap DSCR condition continues to exist until the DSCR exceeds the Cash Trap DSCR for two consecutive calendar months. During a Cash Trap DSCR condition, all cash flow in excess of amounts required to make debt service payments, to fund required reserves, to pay management fees and budgeted operating expenses and to make other payments required under the indenture, referred to as excess cash flow, will be deposited into a reserve account instead of being released to the applicable issuer.

(3) An amortization period commences if the DSCR is equal to or below 1.15x (the “Minimum DSCR”) at the end of any calendar month and continues to exist until the DSCR exceeds the Minimum DSCR for two consecutive calendar months.

The Partnership is subject to covenants customary for notes issued in rated securitizations. Among other things, the obligors are prohibited from incurring other indebtedness for borrowed money or further encumbering their assets (as defined in the applicable agreement). Under the terms of the applicable indenture, the obligors will be permitted to issue additional notes under certain circumstances, including so long as the DSCR of the issuer is at least 1.5x to 1.0x for the 2019 Secured Notes and at least 2.0x to 1.0x for the 2017 Secured Notes. As of December 31, 2020, the Partnership was in compliance with all financial covenants required under the Secured Notes.

Other Secured Debt

On September 25, 2020, the Partnership assumed a Property Assessed Clean Energy (“PACE”) special assessment bond of $3.5 million in connection with a data center acquisition during the third quarter of 2020. The financing agreement is a previous owner-arranged financing agreement dated July 1, 2018 in which PACE bonds were issued by local municipality to the then current property owner for the purpose of financing energy efficiency improvements to the property. These bonds are secured by the property and mature on February 14, 2038. Payments are made semi-annually over the term. The Partnership has assumed the secured debt, which is included in secured notes, net in the Consolidated Balance Sheet.

The Secured Notes’ annual principal payment amounts due as of December 31, 2020, are as follows (in thousands):

2021	$	6,117
2022(1)		72,569

Interest Expense

For the years ended December 31, 2020, 2019 and 2018, the Partnership incurred interest expense, excluding amounts related to discontinued operations, of $17.3 million, $17.5 million and $24.3 million, respectively, and had interest payable of $0.3 million and $0.5 million as of December 31, 2020 and 2019, respectively. Additionally, the Partnership recorded deferred loan costs and amortization of discount on secured notes, which is included in interest expense, of $2.5 million, $3.1 million and $3.8 million for the years ended December 31, 2020, 2019 and 2018, respectively. In connection with the amendment of the credit facility on November 15, 2018, the unamortized balance of the deferred loan costs totaling $0.2 million was recorded as a loss on extinguishment of debt during the year ended December 31, 2018.

During the years ended December 31, 2020, 2019 and 2018, the Partnership recorded a loss, excluding amounts related to discontinued operations, of $6.2 million, a loss of $6.1 million and a gain of $1.4 million, respectively, resulting from the change in fair value of the interest rate swap agreements which is reflected as an unrealized gain (loss) on derivatives on the consolidated statements of operations. In June 2020, the Partnership used proceeds from the sale of the European outdoor advertising portfolio to terminate certain interest rate swap agreements for approximately $7.6 million, including approximately $3.3 million for the GBP denominated interest rate swap agreement with a notional value of £38 million. As of December 31, 2019, the GBP swap agreement had a fair value liability of $1.7 million, which was reclassified to liabilities held for sale in prior period to exclude discontinued operations (Note 4). Additionally, for all periods presented, foreign currency transaction gains and losses resulting from the changes in exchange rates affecting mark-to-market adjustments on the GBP interest rate swap agreement were reclassified to discontinued operations (Note 9).

The fair value of the interest rate swap agreements is derived based on Level 2 inputs. To illustrate the effect of movements in the interest rate market, the Partnership performed a market sensitivity analysis on its outstanding interest rate swap agreements. The Partnership applied various basis point spreads to the underlying interest rate curve of the derivative in order to determine the instruments’ value including change in fair value at December 31, 2020. The following table summarizes the results of the analysis performed (in thousands):

Unit-Based Compensation

12. Unit-Based Compensation 

Compensation of our Directors

On January 25, 2018 the board of directors of the General Partner adopted the Amended and Restated Non-Employee Director Compensation Plan that provides each director that is neither an officer of the General Partner nor an employee or an affiliate of the General Partner with annualized compensation consisting of $40,000 in cash, payable quarterly, and an annual grant of Common Units valued at $40,000 and additional cash compensation for attending meetings of the board of directors of the General Partner or a committee thereof. Additionally, the chairman of the audit committee of the board of directors shall be entitled to additional annualized cash compensation of $15,000 and the chairman of any other committee of the board of directors, as may be established at any time, shall be entitled to an amount in cash as determined by the board of directors.

Our Long‑Term Incentive Plan

In connection with the IPO, the board of directors of the General Partner adopted the Landmark Infrastructure Partners LP 2014 Long-Term Incentive Plan (the “LTIP”). The LTIP provides for the grant, from time to time at the discretion of the board of directors of the General Partner or any committee thereof that may be established for such purpose or by any delegate of the board of directors or such committee, subject to applicable law (the “plan administrator”), of equity-based awards. The purpose of the LTIP is to promote the interests of the Partnership and the General Partner by providing incentive compensation awards to individuals providing services to the Partnership or the General Partner to encourage superior performance. The LTIP is also intended to enhance the ability of the Partnership and the General Partner to attract and retain the services of individuals who are essential for the growth and profitability of the Partnership and the General Partner and to encourage these individuals to devote their best efforts to advancing the business of the Partnership and the General Partner. The LTIP will initially limit the number of units that may be delivered pursuant to vested awards to 785,000 Common Units, subject to proportionate adjustment in the event of unit splits and similar events, with such amount increased annually on the first day of each calendar year beginning January 1, 2016 and ending on and including January 1, 2024 by a number of Common Units equal to the least of (i) 1,570,000 Common Units, (ii) 2% of the total number of common units outstanding on the last day of the immediately preceding calendar year and (iii) such smaller number of Common Units as determined by the board of directors of the General Partner. Common Units subject to awards that are cancelled, forfeited, withheld to satisfy exercise prices or tax withholding obligations, or otherwise terminated without delivery of the Common Units will be available for delivery pursuant to other awards. We have granted 7,368, 10,631 and 3,826 units under our LTIP as compensation to our Non-Employee Directors during the years ended December 31, 2020, 2019 and 2018, respectively, and no other awards were granted to any of our executive officers.

On December 4, 2019, the Partnership filed a universal shelf registration statement on Form S-3 with the SEC. The shelf registration statement was declared effective by the SEC on January 30, 2020 and permits us to issue and sell, from time to time, common and preferred units representing limited partner interests in us, and debt securities up to an aggregate amount of $750.0 million.

Common Units

On February 16, 2016, the Partnership filed a shelf registration statement on Form S-4 with the SEC. The shelf registration statement was declared effective on March 10, 2016 and permits us to offer and issue, from time to time, an aggregate of up to 5,000,000 Common Units in connection with the acquisition by us or our subsidiaries of other businesses, assets or securities. No acquisitions were completed during the year ended December 31, 2020 and 2019 under the Unit Exchange Program. During the year ended December 31, 2018, under the Unit Exchange Program we completed acquisitions of 28 tenant sites in exchange for 508,157 Common Units, valued at approximately $7.6 million.

On February 16, 2016, the Partnership established a Common Unit at-the-market offering program (the “2016 Common Unit ATM Program”) that expired on December 30, 2018, therefore, no Common Units were issued under the 2016 Common Unit ATM Program during the years ended December 31, 2020 and 2019. During the year ended December 31, 2018, the Partnership issued 27,830 Common Units under the 2016 Common Unit ATM Program, generating proceeds of approximately $0.5 million before issuance costs.

On May 3, 2019, the Partnership established a Common Unit at-the-market offering program (the “2019 Common Unit ATM Program”) pursuant to which we may sell, from time to time, Common Units having an aggregate offering price of up to $50.0 million pursuant to our previously filed and effective registration statement on Form S-3. The net proceeds from sales under the 2019 Common Unit ATM Program will be used for general partnership purposes, which may include, among other things, the repayment of indebtedness and to potentially fund future acquisitions. During the year ended December 31, 2020, 109,724 Common Units were issued under the 2019 Common Unit ATM Program generating proceeds of approximately $1.8 million before issuance costs. No Common Units were issued under the 2019 Common Unit ATM Program during the year ended December 31, 2019.

On February 28, 2020, the Partnership replaced the 2019 Common Unit ATM Program and established a new Common Unit at-the-market offering program (the “2020 Common Unit ATM Program”) pursuant to which we may sell, from time to time, Common Units having an aggregate offering price of up to $50.0 million pursuant to our previously filed and effective registration statement on Form S-3. The net proceeds from sales under the 2020 Common Unit ATM Program will be used for general partnership purposes, which may include, among other things, the repayment of indebtedness and to potentially fund future acquisitions. No Common Units were issued under the 2020 Common Unit ATM Program during the year ended December 31, 2020.

Subordinated Units

Our Partnership Agreement provides that, during the subordination period, the Common Units have the right to receive distributions of available cash from operating surplus each quarter in an amount equal to $0.2875 per Common Unit, which amount is defined in our Partnership Agreement as the minimum quarterly distribution, plus any arrearages in the payment of the minimum quarterly distribution on the Common Units from prior quarters, before any distributions of available cash from operating surplus may be made on the subordinated units. These units are deemed “subordinated” because for a period of time, referred to as the subordination period, the subordinated units are not entitled to receive any distributions until the Common Units have received the minimum quarterly distribution plus any arrearages in the payment of the minimum quarterly distribution on the Common Units from prior quarters. Furthermore, no arrearages will accrue or be payable on the subordinated units. The practical effect of the subordinated units is to increase the likelihood that, during the subordination period, there will be available cash to be distributed on the Common Units. The requirements under our Partnership Agreement for the conversion of all the subordinated units into common units were satisfied upon the payment of our quarterly cash distribution on February 14, 2018. Therefore, effective February 15, 2018, all of our subordinated units which are owned by Landmark, were converted on a one-for-one basis into common units. The conversion of subordinated units does not impact the amount of cash distributions or total number of outstanding units.

Preferred Units

On June 24, 2016, the Partnership established a Series A Preferred Unit at-the-market offering program (the “2016 Series A Preferred Unit ATM Program”), that expired on December 30, 2018, therefore, no Series A Preferred Units were issued under the 2016 Series A ATM Program during the years ended December 31, 2020 and 2019. During the year ended December 31, 2018, the Partnership issued 24,747 Series A Preferred Units under the 2016 Series A Preferred Unit ATM Program, generating proceeds of approximately $0.6 million before issuance costs.   

On March 30, 2017, the Partnership established a Series B Preferred Unit at-the-market offering program (the “Series B Preferred Unit ATM Program”), pursuant to which we may sell, from time to time, Series B Preferred Units having an aggregate offering price of up to $50.0 million pursuant to our previously filed and effective registration statement on Form S-3. The net proceeds from sales under the Series B Preferred Unit ATM Program will be used for general Partnership purposes, which may include, among other things, the repayment of indebtedness and to potentially fund future acquisitions. During the year ended December 31, 2020 and 2019, the Partnership issued 84,139 and 81,778 Series B Preferred Units, respectively, under our Series B Preferred Unit ATM Program, generating proceeds of approximately $2.2 million and $2.1 million before issuance costs, respectively. No Series B Preferred Units were issued under our Series B Preferred Unit ATM Program during the year ended December 31, 2018. As of December 31, 2020, we have $30.2 million remaining available to be issued under the Series B Preferred Unit ATM Program.

On May 3, 2019, the Partnership established a Series A Preferred Unit at-the-market offering program (the “2019 Series A ATM Program” and together with the 2016 Series A Preferred Unit ATM Program, Series B Preferred Unit ATM Program and Common Unit ATM Program the “ATM Programs”) pursuant to which we may sell, from time to time, Series A Preferred Units having an aggregate offering price of up to $50.0 million pursuant to our previously filed and effective registration statement on Form S-3. The net proceeds from sales under the 2019 Series A ATM Program will be used for general Partnership purposes, which may include, among other things, the repayment of indebtedness and to potentially fund future acquisitions. During the year ended December 31, 2020 and 2019, the Partnership issued 23,287 and 128,892 Series A Preferred Units, respectively, under our 2019 Series A ATM Program, generating proceeds of approximately $0.6 million and $3.3 million, respectively before issuance costs. As of December 31, 2020, we have $46.1 million remaining available to be issued under the 2019 Series A ATM Program.

On February 28, 2020, the Partnership replaced the 2019 Series A ATM Program and established a new Series A Preferred Unit at-the-market offering program (the “2020 Series A ATM Program”) pursuant to which we may sell, from time to time, Series A Preferred Units having an aggregate offering price of up to $50.0 million pursuant to our previously filed and effective registration statement on Form S-3. The net proceeds from sales under the 2020 Series A ATM Program will be used for general partnership purposes, which may include, among other things, the repayment of indebtedness and to potentially fund future acquisitions. During the year ended December 31, 2020, the Partnership issued 43,515 Series A Preferred Units under our 2020 Series A ATM Program, generating proceeds of approximately $1.1 million before issuance costs.

On February 28, 2020, the Partnership replaced the Series B ATM Program and established a new Series B Preferred Unit at-the-market offering program (the “2020 Series B ATM Program”) pursuant to which we may sell, from time to time, Series B Preferred Units having an aggregate offering price of up to $50.0 million pursuant to our previously filed and effective registration statement on Form S-3. The net proceeds from sales under the 2020 Series B ATM Program will be used for general partnership purposes, which may include, among other things, the repayment of indebtedness and to potentially fund future acquisitions. No Series B Preferred Units were issued under the 2020 Series B ATM Program during the year ended December 31, 2020.

Mezzanine Equity

On April 2, 2018, the Partnership completed a public offering of 2,000,000 Series C Floating-to-Fixed Rate Cumulative Perpetual Redeemable Convertible Preferred Units (“Series C Preferred Units” and together with the Series A Preferred Units and Series B Preferred Units the “Preferred Units”), representing limited partner interest in the Partnership, at a price of $25.00 per unit. We received net proceeds of approximately $47.5 million after deducting underwriters’ discounts and offering expenses paid by us of $2.5 million. We used substantially all net proceeds to repay a portion of the borrowings under our revolving credit facility. In connection with the closing of the Series C Preferred Units offering, the Partnership executed the Fourth Amended and Restated Agreement of Limited Partnership of Landmark Infrastructure Partners LP (the “Amended Partnership Agreement”) for the purpose of defining the preferences, rights, powers and duties of holders of the Series C Preferred Units.

Distributions on the Series C Preferred Units are cumulative from the date of original issue and will be payable quarterly in arrears on the 15th day of February, May, August and November of each year, when, as and if declared by the board of directors of our General Partner. The initial distribution on the Series C Preferred Units was paid on May 15, 2018 in an amount equal to $0.2090 per unit. Distributions accruing from, and including, the date of original issuance and to, but excluding May 15, 2025 will accrue at an annual rate equal to the greater of (i) 7.00% per annum, and (ii) the sum of (a) three-month LIBOR as calculated on each applicable date of determination and (b) 4.698% per annum, based on the $25.00 liquidation preference per Series C Preferred Unit. Distributions accruing on and after May 15, 2025 will accrue at 9.00% per annum of the stated liquidation preference.

Holders of Series C Preferred Units, at their option, may, at any time and from time to time, convert some or all of their Series C Preferred Units based on an initial conversion rate of 1.3017 common units per Series C Preferred Unit. In the event of a fundamental change, holder of the Series C Preferred Units, at their option, may convert some or all of their Series C Preferred Units into the greater of (i) a number of common units plus a make-whole premium and (ii) a number of common units equal to the lessor of (a) the liquidation preference divided by the market value of our common units on the effective date of such fundamental change and (b) 11.13 (subject to adjustments). On May 15, 2025, May 15, 2028, and each subsequent five-year anniversary date thereafter (each such date, a “designated redemption date”), each holder of Series C Preferred Units shall have the right (a “redemption right”) to require the Partnership to redeem any or all of the Series C Preferred Units held by such holder outstanding on such designated redemption date at a redemption price equal to the liquidation preference of $25.00, plus all accrued and unpaid distributions to, but not including, in each case out of funds legally available for such payment and to the extent not prohibited by law, the designated redemption date (the “put redemption price”). At our option we may pay the redemption in our common units or cash, subject to certain limitations.

At any time on or after May 20, 2025, the Partnership shall have the option to redeem the Series C Preferred Units, in whole or in part, at a redemption price of $25.00 per Series C Preferred Unit plus an amount equal to all accumulated and unpaid distributions thereon to the date of redemption, whether or not declared.

The Partnership has classified the Series C Preferred Units as mezzanine equity in the accompanying consolidated balance sheets based upon the terms and conditions of the holder’s redemption option. Issuance costs related to the Series C Preferred Units classified as mezzanine equity are initially recorded as a reduction of the units balances and accreted up to the redemption value. During the years ended December 31, 2020 and 2019, 6,000 and 11,300 Series C Preferred Units were converted into 7,810 and 14,708 Common Units, respectively, based on the holder’s option.

Net Income (Loss) Per Limited Partner Unit

Earnings Per Unit [Abstract]

Net Income (Loss) Per Limited Partner Unit

14. Net Income (Loss) Per Limited Partner Unit

Landmark’s subordinated units and the General Partner’s incentive distribution rights meet the definition of a participating security and therefore we are required to compute income per unit using the two-class method under which any excess of distributions declared over net income shall be allocated to the partners based on their respective sharing of income specified in the Amended Partnership Agreement. Payments made to our unitholders are determined in relation to actual distributions declared and are not based on the net income (loss) allocations used in the calculation of net income (loss) per unit.

Net income (loss) per unit applicable to limited partners (including subordinated unitholders) is computed by dividing limited partners’ interest in net income (loss), after deducting any Preferred Unit distributions and General Partner incentive distributions, by the weighted-average number of outstanding common and subordinated units. Diluted net income (loss) per unit includes the effects of potentially dilutive units on our common and subordinated units and Series C Preferred Units. Net income (loss) related to the Drop-down Assets prior to the Partnership’s acquisition dates of each transaction is allocated to the General Partner.

Effective February 15, 2018, all of our subordinated units, which were owned by Landmark, were converted on a one-for-one basis into common units. The subordinated units were only allocated the excess of distributions declared over net income through the conversion date.

The calculation of the undistributed net loss attributable to common and subordinated unitholders for the years ended December 31, 2020, 2019 and 2018 is as follows (in thousands):

	Year Ended December 31,
	2020			2019			2018

Undistributed income (loss) from continuing operations	$	(21,238	)	$	(27,817	)	$	67,591

(1) The General Partner irrevocably waived its right to receive the incentive distribution and incentive allocations related to each quarterly distribution during the year ended December 31, 2019 and for the three months ended September 30, 2018 and December 31, 2018. For purposes of determining net income per common unit, the amount otherwise due to the general partner has been referenced as a deemed distribution.

The calculation of net income (loss) per unit related to the Partnership for the years ended December 31, 2020, 2019 and 2018 is as follows (in thousands, except per unit data):

Diluted(1)(2)	$	0.65		$	0.33		$	3.97		$	(0.78	)

(1) Diluted earnings per unit takes into account the potential dilutive effect of common units that could be issued by the Partnership in conjunction with the Series C Preferred Units conversion features. Potential common unit equivalents are anti-dilutive for the years ended December 31, 2020 and 2019 and, as a result, have been excluded in the determination of diluted income (loss) from continuing operations per common unit and net income (loss) per common unit. Potential common unit equivalents were dilutive for the year ended December 31, 2018 and, as a result, have been included in the determination of diluted income (loss) from continuing operations per common and subordinated unit and net income (loss) per common and subordinated unit.

(2) The Partnership Agreement provides that when the subordination period ends, each outstanding subordinated unit will convert into one Common Unit and will thereafter participate pro rata with the other Common Units in distributions of available cash. Effective February 15, 2018, all of the subordinated units, which were owned by Landmark, were converted on a one-for-one basis into Common Units. The diluted effect of Landmark’s subordinated units is reflected using the “if-converted method” which assumes conversion of the subordinated units into Common Units and excludes the subordinated distributions from the calculation, as the “if-converted method” is more dilutive.

Fair Value of Financial Instruments

Fair Value Disclosures [Abstract]

Fair Value of Financial Instruments

15. Fair Value of Financial Instruments

The fair value for certain financial instruments is derived using a combination of market quotes, pricing models and other valuation techniques that involve significant management judgment. The price transparency of financial instruments is a key determinant of the degree of judgment involved in determining the fair value of the Partnership’s financial instruments. Financial instruments for which actively quoted prices or pricing parameters are available and for which markets contain orderly transaction will generally have a higher degree of price transparency than financial instruments for which markets are inactive or consist of non‑orderly trades. The Partnership evaluates several factors when determining if a market is inactive or when market transactions are not orderly. The following is a summary of the methods and assumptions used by management in estimating the fair value of each class of assets and liabilities for which it is practicable to estimate the fair value:

Cash and cash equivalents, rent receivables, net accounts payable and accrued liabilities:  The carrying values of these balances approximate their fair values because of the short‑term nature of these instruments.

Revolving credit facility:  The fair value of the Partnership’s revolving credit facility is estimated using a discounted cash flow analysis based on management’s estimates of current market interest rates for instruments with similar characteristics, including remaining loan term, loan‑to‑value ratio, type of collateral and other credit enhancements. Additionally, since a quoted price in an active market is generally not available for the instrument or an identical instrument, the Partnership measures fair value using a valuation technique that is consistent with the principles of fair value measurement which typically considers what management believes is a market participant rate for a similar instrument. The Partnership classifies these inputs as Level 3 inputs. The fair value of the Partnership’s revolving credit facility is considered to approximate the carrying value because the interest payments are based on LIBOR rates that reset every month.

Secured notes: The Partnership determines fair value of its secured notes utilizing various Level 2 sources including quoted prices and indicative quotes (non-binding quotes) from brokers that require judgment to interpret market information. Quotes from brokers require judgment and are based on the brokers’ interpretation of market information, including implied credit spreads for similar borrowings on recent trades or bid/ask prices or quotes from active markets if available.

Investments in receivables:  The Partnership’s investments in receivables are presented in the accompanying consolidated balance sheets at their amortized cost net of recorded reserves and not at fair value. The fair values of the receivables were estimated using an internal valuation model that considered the expected cash flow of the receivables and estimated yield requirements by market participants with similar characteristics, including remaining loan term, and credit enhancements. The Partnership classifies these inputs as Level 3 inputs.

Interest rate swap agreements:  The Partnership’s interest rate swap agreements are presented at fair value on the accompanying consolidated balance sheets. The valuation of these instruments is determined using a proprietary model that utilizes observable and unobservable inputs. A majority of the inputs are observable with the only unobservable inputs relating to the lack of performance risk on the part of the Partnership or the counter party to the instrument. As such, the Partnership classifies these inputs as Level 2 inputs. The proprietary model uses the contractual terms of the derivatives, including the period to maturity, as well as observable market‑based inputs, including the interest rate curves and volatility. The fair values of interest rate swaps are estimated using the market standard methodology of netting the discounted fixed cash payments and the discounted expected variable cash receipts. The variable cash receipts are based on an expectation of interest rates (forward curves) derived from observable market interest rate curves. In addition, credit valuation adjustments, which consider the impact of any credit risk to the contracts, are incorporated in the fair values to account for potential nonperformance risk.

The table below summarizes the carrying amounts and fair values of financial instruments which are not carried at fair value on the face of the financial statements. Prior period amounts have been revised to exclude discontinued operations (in thousands):

	December 31,
	2020				2019
	Carrying amount		Fair Value		Carrying amount		Fair Value
Investments in receivables, net	$	5,101	$	5,105	$	5,653	$	5,650
Revolving credit facility		214,200		214,200		179,500		179,500
Secured Notes, net		279,677		298,097		217,098		221,577

Disclosure of the fair values of financial instruments is based on pertinent information available to the Partnership as of the period end and requires a significant amount of judgment. Despite increased capital market and credit market activity, transaction volume for certain financial instruments remains relatively low. This has made the estimation of fair values difficult and, therefore, both the actual results and the Partnership’s estimate of value at a future date could be materially different.

For the years ended December 31, 2020 and 2019, the Partnership measured the following assets and liabilities at fair value on a recurring basis. Prior period amount has been revised to exclude discontinued operations (in thousands):

	December 31,
	2020		2019
Derivative Liabilities(1)	$	3,435	$	1,474

(1) Fair value is calculated using level 2 inputs. Level 2 inputs are quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model‑derived valuations in which significant inputs and significant value drivers are observable in active markets.

General and Administrative Reimbursement

Under the Amended Partnership Agreement, we are required to reimburse our general partner and its affiliates for all costs and expenses that they incur on our behalf for managing and controlling our business and operations. Except to the extent specified under our amended Omnibus Agreement with Landmark (the “Omnibus Agreement”), which was amended on January 30, 2019, our general partner determines the amount of these expenses and such determinations must be made in good faith under the terms of the Amended Partnership Agreement. Under the amended Omnibus Agreement, we are required to reimburse Landmark for expenses related to certain general and administrative services Landmark provides to us in support of our business, subject to a quarterly cap equal to 3% of our revenue during the current calendar quarter. This cap on expenses will last until the earlier to occur of: (i) the date on which our revenue for the immediately preceding four consecutive fiscal quarters exceeded $120 million and (ii) November 19, 2021. The full amount of general and administrative expenses incurred will be reimbursed by Landmark and reflected on our income statements, and to the extent such general and administrative expenses exceed the cap amount, the amount of such excess will be reflected in our financial statements as a capital contribution rather than as a reduction of our general and administrative expenses, except for expenses that would otherwise be allocated to us, which are not included in the amount of general and administrative expenses. These expenses include salary, bonus, incentive compensation and other amounts paid to persons who perform services for us or on our behalf and expenses allocated to our general partner by its affiliates. For the years ended December 31, 2020, 2019 and 2018, Landmark reimbursed us $3.0 million, $3.7 million and $2.8 million, respectively, for expenses related to certain general and administrative services that exceeded the cap. During the years ended December 31, 2020, 2019 and 2018, $0.3 million, $0.3 million and less than $0.1 million, respectively, of management fees related to our unconsolidated joint venture that is not subject to the cap and is treated as a capital contribution from Sponsor. Additionally, indemnification of $0.4 million related to property taxes is included in capital contributions from Sponsor on the Consolidated Statements of Equity and Mezzanine Equity for 2019. Additionally, indemnification of $1.0 million related to certain assets and is included in capital contributions from Sponsor on the Consolidated Statement of Equity and Mezzanine Equity for 2018.

Patent License Agreement

We entered into a Patent License Agreement (the “License Agreement”) with American Infrastructure Funds, LLC (“AIF”), an affiliate of the controlling member of Landmark. Under the License Agreement, AIF granted us a nonexclusive, perpetual license to practice certain patented methods related to the apparatus and method for combining easements under a master limited partnership. We have agreed to pay AIF a license fee of $50,000 for the second year of the License Agreement, and thereafter, an amount equal to the greater of (i) one‑tenth of one percent (0.1%) of our gross revenue received during such contract year; or (ii) $100,000. During the years ended December 31, 2020, 2019 and 2018, we incurred $0.1 million, respectively, of license fees related to the AIF patent license agreement.

Right of First Offer

In accordance with the Partnership’s omnibus agreement, certain other investment funds managed by Landmark had granted us a right of first offer (“ROFO”) on real property interests that they owned or acquired before selling or transferring those assets to any third party. During the years ended December 31, 2018, the Partnership waived its ROFO on certain assets in investment funds managed by Landmark. During the year ended December 31, 2018, the Partnership completed the following ROFO acquisitions:

										Common Units

See further discussion in Note 3, Acquisitions for additional information.

Secured Tenant Site Assets’ Management Fee

In connection with the issuance of the Secured Notes, the Partnership entered into applicable management agreements with the General Partner. Pursuant to the applicable management agreements, our General Partner will perform those functions reasonably necessary to maintain, manage and administer the Secured Tenant Site Assets for a monthly management fee equal to (i) 1.5% of the Secured Tenant Site Assets’ operating revenue, as defined by the applicable management agreements for the 2017 secured notes; (ii) 0.5% of operating revenue for the 4.38% senior secured notes and (iii) 2% of gross revenue for the 2019 secured notes. The Secured Tenant Site Assets’ management fee to Landmark will be treated as a capital distribution to Landmark. Landmark will reimburse us for the fees paid with the reimbursement treated as a capital contribution. We incurred $0.1 million, $0.3 million and less than $0.1 million of Secured Tenant Site Assets’ management fees during the years ended December 31, 2020, 2019 and 2018, respectively.

In connection with the formation of the unconsolidated JV, the JV assumed the 2018 Secured Notes. Pursuant to the applicable management agreement, our General Partner will perform those functions reasonably necessary to maintain, manage and administer the 2018 Secured Tenant Site Assets for a monthly management fee equal to 1.5% of the Secured Tenant Site Assets’ operating revenue, subject to a maximum of $46 per tenant site asset. Landmark will reimburse us for the management fees paid by the unconsolidated JV with the reimbursement treated as a capital contribution. For the years ended December 31, 2020, 2019 and 2018, the unconsolidated JV incurred $0.3 million, $0.3 million and $0.1 million of management fees and included in capital contributions from Sponsor on the Consolidated Statement of Equity and Mezzanine Equity.

Acquisition of Real Property Interests

In connection with third party acquisitions, Landmark will be obligated to provide acquisition services to us, including asset identification, underwriting and due diligence, negotiation, documentation and closing, at the reasonable request of our General Partner, but we are under no obligation to utilize such services. We may pay Landmark reasonable fees, as mutually agreed to by Landmark and us, for providing these services. These fees will not be subject to the cap on general and administrative expenses described above. During the year ended December 31, 2020, the Partnership incurred $4.3 million of acquisition fees related to the third and fourth quarter 2020 direct acquisitions. There were no such fees incurred during the years ended December 31, 2019 and 2018.

Incentive Distribution Rights

Cash distributions will be made to our General Partner in respect of its ownership of all IDRs, which entitle our General Partner to receive increasing percentages, up to a maximum of 50%, of the available cash we distribute from operating surplus (as defined in our Amended Partnership Agreement) in excess of $0.2875 per unit per quarter. There were no incentive distributions and incentive allocations during the year ended December 31, 2020. The General Partner irrevocably waived its right to receive the incentive distribution and incentive allocations related to each quarterly distribution during the year ended December 31, 2019 and for the three months ended September 30, 2018 and December 31, 2018, totaling $0.8 million and $0.4 million, which is treated as a deemed contribution in the consolidated statements of equity and mezzanine equity and as a deemed distribution for purposes of determining net income per common unit. During the year ended December 31, 2018, we paid $0.4 million of incentive distribution rights.

Due from Affiliates

At December 31, 2020 and 2019, the General Partner and affiliates owed $1.3 million and $1.1 million, respectively, to the Partnership primarily for current quarter general and administrative reimbursement, unconsolidated JV management fees and for rents received on our behalf, offset by rents received on behalf of the unconsolidated JV.

Segment Reporting [Abstract]

Segment Information

17. Segment Information

Prior to June 30, 2020, the Partnership had the following three reportable segments: (i) wireless communication, (ii) outdoor advertising, and (iii) renewable power generation. Prior period amounts have been revised to reflect classification of the European outdoor advertising portfolio as a discontinued operation and presentation of the assets of the European outdoor advertising portfolio as assets held for sale. Consequently, an evaluation of segment reporting thresholds resulted in changes in our segment presentation for all prior periods presented. As of June 30, 2020, the Partnership had the following four reportable segments: (i) wireless communication, (ii) digital infrastructure, (iii) outdoor advertising and (iv) renewable power generation for all periods presented.

The Partnership’s wireless communication segment consists of leasing infrastructure and real property interests and providing financing to companies in the wireless communication industry in the United States, Canada, and Australia. The Partnership’s outdoor advertising segment consists of leasing real property interests to companies in the outdoor advertising industry in the United States, Canada and Australia. The Partnership’s renewable power generation segment consists of leasing real property interests and providing financing to companies in the renewable power industry in the United States. The Partnership’s digital infrastructure segment consists of leasing real property interests to companies in the digital infrastructure industry in the United States and Canada. Items that are not included in any of the reportable segments are included in the corporate category.

The reportable segments are strategic business units that offer different products and services. They are commonly managed as all four businesses require similar marketing and business strategies. Because our tenant lease arrangements are mostly triple net or effectively triple net, we evaluate our segments based on revenue. We believe this measure provides investors relevant and useful information because it is presented on an unlevered basis.

The statements of operations for the reportable segments are as follows:

Commitments and Contingencies

18. Commitments and Contingencies

The Partnership’s commitments and contingencies include customary claims and obligations incurred in the normal course of business. In the opinion of management, these matters will not have a material effect on the Partnership’s combined financial position.

There has been consolidation in the wireless communication industry historically that has led to certain lease terminations. The past consolidation in the wireless industry has led to rationalization of wireless networks and reduced demand for tenant sites. On April 1, 2020, T-Mobile and Sprint completed their merger. Significant consolidation among our tenants in the wireless communication industry (or our tenants’ sub‑lessees) may result in the decommissioning of certain existing communications sites, because certain portions of these tenants’ (or their sub‑lessees’) networks may be redundant. The impact of any future consolidation in the wireless communication industry and the termination of additional leases in our portfolio would result in lower rental revenue and may lead to impairment of our real property interests or other adverse effects to our business.

As of December 31, 2020, the Partnership had approximately $63.5 million of real property interests subject to subordination to lenders of the underlying property. To the extent a lender forecloses on a property the Partnership would take impairment charges for the book value of the asset and no longer be entitled to the revenue associated with the asset.

Substantially all of our tenant sites are leased to tenants under triple net or effectively triple-net lease arrangements, which require the tenant or the underlying property owner to pay all utilities, property taxes, insurance and repair and maintenance costs. Our overall financial results could be impacted to the extent the owners of the fee interest in the real property or our tenants do not satisfy their obligations.

Tenant Concentration

19. Tenant Concentration

For the years ended December 31, 2020, 2019 and 2018, the Partnership had the following tenant revenue concentrations. Prior period concentrations have been revised to exclude discontinued operations:

	Year Ended December 31,
Tenant	2020			2019			2018
T-Mobile		14.0	%		15.6	%		18.3	%
Clear Channel Outdoor		10.6	%		13.5	%		11.8	%

Most tenants are subsidiaries of these companies but have been aggregated for purposes of showing revenue concentration. Financial information for these companies can be found at www.sec.gov.

The loss of any one of our large customers as a result of consolidation, merger, bankruptcy, insolvency, network sharing, roaming, joint development, resale agreements by our customers or otherwise may result in (1) a material decrease in our revenue, (2) uncollectible account receivables, (3) an impairment of our deferred site rental receivables, wireless infrastructure assets, site rental contracts or customer relationships intangible assets, or (4) other adverse effects to our business.

Income Taxes

20. Income Taxes

The Partnership is not a taxable entity for United States federal income tax purposes instead any tax liability on our net income is generally borne by our partners through their allocation of taxable income. The Partnership files in various state jurisdictions that generally follow this federal treatment.

Our consolidated corporate U.S. subsidiary Asset OpCo conducts certain activities that may not generate qualifying REIT income and is therefore taxable as a corporation for U.S. federal and state income tax purposes. Additionally, certain consolidated corporate foreign subsidiaries of the Partnership are subject to income tax in the foreign jurisdictions where they operate. 

The following information pertains to the Partnership’s income taxes on a consolidated basis.

Consolidated Partnership income before income tax expense by geographic area is as follows (in thousands):

	Year Ended December 31,
	2020		2019		2018
Domestic	$	26,137	$	21,076	$	116,045
Foreign(1)		3,031		4,313		3
Total	$	29,168	$	25,389	$	116,048

(1) For all periods presented, amounts include the effects that are reported in discontinued operations.

For the years ended December 31, 2020, 2019 and 2018, income tax expense (benefit) consisted of the following (in thousands):

	Year Ended December 31,
	2020			2019			2018
Current
Domestic	$	247		$	2,397		$	(10	)
Foreign (1)		354			725			15
Deferred
Domestic		(727	)		718			370
Foreign (1)		176			(57	)		(148	)
Income tax expense	$	50		$	3,783		$	227

(1) For all periods presented, amounts include the effects that are reported in discontinued operations.

The statutory federal income tax rate is 21 percent for the years ended December 31, 2020, 2019 and 2018 and the foreign income tax rates range from 15 percent to 39 percent. The difference between income tax expense (benefit) recorded by us and income taxes computed by applying the statutory corporate income tax rates to the consolidated Partnership income before income tax expense (benefit) is due to the fact that the majority of our income is not subject to federal, state and foreign income tax as described above.

Reconciliation between the U.S. statutory rate and the effective rate from income from continuing operations before income tax expense (benefit) is as follows:

	Year Ended December 31,
	2020			2019			2018
Statutory tax rate		21	%		21	%		21	%
Adjustment to reflect MLP/REIT status		(21	)%		(10	)%		(21	)%
Foreign taxes		(3	)%		1	%		—	%
Valuation allowance		1	%		—	%		—	%
Change in tax law		—	%		—	%		—	%
Other		(2	)%		1	%		—	%
Effective tax rate		(4	)%		13	%		—	%

Deferred income taxes are recorded based on temporary differences between the financial statement carrying amounts and the tax basis of assets and liabilities. The statutory federal income tax rate of 21 percent is used for valuation of the deferred tax assets and liabilities and is based upon the tax rate expected to be in place when the deferred tax assets and liabilities are recognized. Asset OpCo and the corporate foreign subsidiaries routinely assesses their ability to realize deferred tax assets. If an entity concludes that it is more likely than not that some or all of the deferred tax assets will not be realized, the tax asset is reduced by a valuation allowance. As of December 31, 2020, the Partnership has a valuation allowance of $0.1 million and believes it is more likely than not that its other deferred tax assets recorded will be realized.

The consolidated domestic and foreign deferred tax asset was $2.8 million and $2.3 million for the years ended December 31, 2020 and 2019, respectively. The increase in the deferred tax asset in the current year is due to an increase in the state tax rate and generated net operating losses.  

As of December 31, 2020, we had an immaterial liability for unrecognized tax benefits. We did not have any significant interest and penalties related to income taxes during the year ended December 31, 2020.

The Partnership had domestic and foreign NOLs for the year ended December 31, 2020, which can be used to offset taxable income in future and prior years, subject to specified limitations. As of December 31, 2020, Asset OpCo and foreign subsidiaries had an NOL carryforward of $2.3 million translating to a deferred tax asset before valuation allowance of $0.5 million and a valuation allowance of $0.1 million. As of December 31, 2018, Asset OpCo had an NOL carryforward of $0.4 million, translating to a deferred tax asset before valuation allowance of less than $0.1 million. In 2019, Asset OpCo fully utilized existing NOL carryforwards.

Basis Of Presentation And Summary Of Significant Accounting Policies [Abstract]

Basis of Presentation and Principles of Consolidated Financial Statements

Basis of Presentation and Principles of Consolidated Financial Statements

During the year ended December 31, 2018, the Partnership completed one drop-down acquisition of 127 tenant sites and related real property interests from the Sponsor and affiliates in exchange for total consideration of $59.9 million (the “Drop-down Acquisitions” or “Drop-down Assets”). There were no Drop-down Acquisitions during the years ended December 31, 2020 and 2019. Drop-down Acquisitions from the Sponsor and affiliates are accounted for prospectively as transfers of net assets in the period in which the transfer occurs at the net carrying value. Any differences between the cash consideration and the net carrying value of the transfer of net assets is allocated to the General Partner.  

On an ongoing basis, we evaluate each legal entity that is not wholly owned by us in accordance with the consolidation guidance. The accompanying consolidated financial statements include the accounts of the Partnership, its wholly-owned subsidiaries and those entities in which it has a controlling interest. Investments in entities that the Partnership does not control are accounted for using the equity or cost method, depending upon the Partnership’s ability to exercise significant influence over operating and financial policies.

The consolidated financial statements were prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). All intercompany transactions and account balances have been eliminated. Management believes that the assumptions and estimates used in the preparation of the underlying consolidated financial statements are reasonable. However, the consolidated financial statements herein do not necessarily reflect what the Partnership’s financial position, results of operations, comprehensive income or cash flows would have been if the Partnership had been a stand-alone entity during the periods presented. As a result, historical financial information is not necessarily indicative of the Partnership’s future results of operations, comprehensive income, financial position or cash flows. All references to tenant sites are unaudited.

Use of Estimates

Use of Estimates

The preparation of the consolidated financial statements, in conformity with GAAP, requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.

Purchase Accounting for Acquisitions

Purchase Accounting for Acquisitions

The Partnership applies the asset acquisition method to all acquired investments of real property interests for transactions that meet the definition of an asset acquisition based on the revised framework for determining whether an integrated set of assets meets the definition of a business. The purchase consideration for the real property interests is allocated to the acquired tangible assets, such as land and building, and the identified intangible assets and liabilities, consisting of the value of perpetual and limited life easements, above-market and below-market leases and in-place leases, based in each case on their fair values. The fair value of the assets acquired and liabilities assumed is typically determined by using the discounted cash flow valuation method using discount rates ranging between 6% and 20% with a weighted average discount rate of 8.5%. In certain instances, such as data center acquisitions, the sales comparison approach is used to determine the fair value of the land assets, the cost approach to determine the fair value of the building and site improvements, and the income approach to determine the fair value of the real property interest and liability assumed. When determining the fair value of intangible assets acquired, the Partnership estimates the applicable discount rate and the timing and amount of future cash flows. Transaction costs related to asset acquisitions are capitalized.

Factors considered in estimating the fair value of tangible and intangible assets acquired include information obtained about each asset as a result of Landmark’s pre-acquisition due diligence and its marketing and leasing activities. In order to calculate the estimated in-place lease value, we employed the income approach in accordance with ASC 805 by multiplying the anticipated market absorption period by the market rent at the time of acquisition for each in-place lease agreement. Based on our experience in the industry, we have determined a range of lease execution timelines to be between one and twelve months. For the in-place lease valuation, we consider a lease-up period of four to eight months to be representative of the market.

We estimated the fair value of real property interests using the income approach. The discount rates used ranged from 6% to 20% with a weighted average discount rate of 8.5%. In certain instances, such as data center acquisitions, the sales comparison approach is used to determine the fair value of the land assets, the cost approach to determine the fair value of the building and site improvements, and the income approach to determine the fair value of the real property interest and liability assumed. The value of tenant relationships has not been separated from in-place tenant lease value for the real estate acquired as such value and its consequence to amortization expense is materially consistent with the in-place tenant lease value for these particular acquisitions. Should future acquisitions of real property interests result in allocating material amounts to the value of tenant relationships, an amount would be separately allocated and amortized over the estimated life of the relationship. The value of in-place leases and customer relationship is amortized to expense over the estimated period the tenant is expected to be leasing the site under the existing terms which typically range from 2 to 20 years. If a tenant lease were to be terminated prior to its stated expiration, all unamortized amounts relating to that lease would be impaired.

The discount rate associated with each asset varies based on the location of an asset (including demographics and zoning restrictions), and other asset specific characteristics. Market rent for each asset is determined based on location of each asset, asset type, zoning restrictions, ground space necessary for the tenant’s equipment, remaining site capacity, visibility (specifically for billboards), and nearby sites.

In allocating the purchase consideration of the identified intangible assets and liabilities of an acquired asset, above-market, below-market and in-place lease values are calculated based on the present value (using a discount rate that reflects the risks associated with the leases acquired) of the difference between (i) the contractual amounts to be paid pursuant to the in-place leases and (ii) management’s estimate of fair market lease rates for the corresponding in-place leases measured over the estimated period the tenant is expected to be leasing the site under the above or below-market terms. The capitalized above-market and below-market lease values are amortized as a decrease or increase, respectively, to rental income over the estimated period the tenant is expected to be leasing the site. Wireless communication and outdoor advertising tenant leases obtained by the Partnership through its acquisition of real property interests are generally cancellable, upon 30 to 180 days’ notice by the tenants, with no significant penalty. Digital infrastructure and renewable power generation tenant leases are generally non-cancellable. With respect to below-market leases, consideration is given to any below-market renewal periods. However, for wireless communication assets, we estimated the above/below-market lease value over an analysis period of the earlier of the lease expiration or 10 years based on estimated useful life of the underlying equipment and assets. For outdoor advertising assets, we estimated the above- or below-market lease value over an analysis period of the earlier of the lease expiration or 20 years, based on a longer estimated useful life of 20 years for billboards.

Real Property Interests and Depreciation and Amortization

Real Property Interests and Depreciation and Amortization

Real property interests consist primarily of land, easements and lease assignments underlying wireless communication, digital infrastructure, outdoor advertising and renewable power generation. The real property interests are typically held as ownership of land or easements to use land, or roof tops, both of which allow us to use the asset for a specific purpose. Real property interests, excluding land, are intangibles that are recorded at cost. Amortization is computed using the straight-line method over the estimated useful lives of the real property interests, which is estimated as the shorter of the revenue generating period of the asset or the term of the real estate rights which range from 12 to 99 years. Depreciation of buildings, site improvements or equipment is computed using the straight-line method over the assets’ estimated useful lives. Real property interests with a perpetual term are not amortized but evaluated periodically for impairment.

The Partnership assesses whether there has been an impairment in the value of long-lived assets whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount to the future estimated net cash flows, undiscounted and without interest, expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the estimated fair value of the assets based upon what a market participant would be willing to pay for the real estate interest. The estimated fair value of the asset group identified for step two testing is based on either Level 3 inputs utilizing the income approach with a market discount rate and estimated cash flows, or Level 2 inputs based upon the sales comparison approach to a similar asset. Assets to be disposed of are reported at the lower of the carrying amount or fair value, less costs to sell utilizing the Level 3 and Level 2 inputs discussed below.

Concurrent with the Partnership’s adoption of ASU No. 2016-02 on January 1, 2019, the Partnership has elected to recognize expense associated with short-term leases (those with a non-cancellable lease term of 12 months or less) under which the Partnership is the lessee on a straight-line basis and not recognize those leases on its consolidated balance sheets. For leases other than short-term operating and finance leases under which the Partnership is the lessee, such as ground leases, the Partnership recognizes a right-of-use asset and related lease liability on its consolidated balance sheet at inception of the lease based on the present value of the remaining minimum rental payments using each respective lease term and a corresponding incremental borrowing rate. Operating lease assets are included in right of use, net and finance lease assets are included in real property interests in the consolidated balance sheets.

Development Operations

Development Operations

The Partnership capitalizes direct construction and development costs, including pre-development costs, interest, and other costs directly related and essential to the development or construction of an asset. The Partnership capitalizes construction and development costs while substantive activities are ongoing to prepare an asset for its intended use. Fluctuations in our development, pre-construction, and construction activities could result in significant changes to expenses and net income. Costs incurred after a project is substantially complete and ready for its intended use are expensed as incurred. Should development, pre-construction, or construction activity cease, interest and certain other costs would no longer be eligible for capitalization and would be expensed as incurred. Expenditures for repairs and maintenance are expensed as incurred. The Partnership computes depreciation on assets placed in service and improvements using the straight-line method over the assets’ estimated useful lives.

Development projects and other similar contracts are assessed to determine whether it continues to meet our investment return standards. Assessments are made separately for each project on a quarterly basis and are affected by the following factors relative to the market in which the asset is located, among others: estimated development and construction costs and projected profitability. When a decision is made to cease construction on certain projects due to market conditions and/or fluctuations in our development strategy, we write off the related capitalized costs, including pre-construction costs. During the year ended December 31, 2019, the Partnership ceased construction on a certain development project and recognized impairment charges of $1.6 million including a write off of $0.1 million in capitalized interest.

Fair Value of Financial Instruments

Fair Value of Financial Instruments

The standard establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable input be used when available. Observable inputs are inputs that the market participants would use in pricing an asset or liability developed based on market data obtained from sources independent of the Partnership. Unobservable inputs are inputs that reflect the Partnership’s assumptions about what market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. The hierarchy is measured in three levels based on the reliability of inputs:

Level 1 – unadjusted quoted prices in active markets that are accessible at the measurement date for identical assets or liabilities.

Level 2 – quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-derived valuations in which significant inputs and significant value drivers are observable in active markets; and,

Level 3 – prices or valuations derived from other valuation methodologies where little or no market data is available that requires inputs that are both significant to the fair value measurement and unobservable, including pricing models, discounted cash flow models and similar techniques.

Cash and Cash Equivalents

Cash and Cash Equivalents

All highly liquid investments with a maturity of three months or less when purchased are considered to be cash and cash equivalents. The Partnership monitors the cash balances in its operating accounts and adjusts the cash balances as appropriate; however, these cash balances could be impacted if the underlying financial institutions fail or are subject to other adverse conditions in the financial markets. To date, the Partnership has experienced no loss or lack of access to cash in the operating accounts.

Restricted Cash

Restricted Cash

Restricted cash primarily consists of amounts pledged as collateral to secure obligations. As of December 31, 2020 and 2019, the amount of restricted cash was $3.2 million and $5.6 million. See Note 10, Debt for additional information.

Accounting for Derivative Financial Instruments and Hedging Activities

Accounting for Derivative Financial Instruments and Hedging Activities

The Partnership utilizes interest rate swap contracts to manage interest costs and risks associated with changing interest rates. These derivative financial instruments are carried at fair value on the consolidated balance sheets, with the change in such fair value being recorded through earnings as an unrealized gain or loss in the consolidated statements of operations.

Investments in Receivables, Net

Investments in Receivables, Net

The Partnership acquired streams of future cash flows associated with real property interests and certain lease arrangements that meet the definition of a financial asset within the wireless communication, outdoor advertising and renewable power generation industries. For certain investments in receivables, the Partnership has no significant rights or obligations associated with the cash flows other than in certain arrangements, to pass a portion of the cash flows received to the owner of the respective lease. Additionally, certain lease arrangements of real property interests meet the definition of a financial asset and are included in investments in receivables in our financial statements. The future cash flow streams are recorded at their net present value based on the estimated net cash flows to be received by the Partnership using the implied discount rate at the date of the acquisition.

Receivables are classified as held-for-investment based on management’s intent and ability to hold the receivables for the foreseeable future or to maturity. Receivables held-for-investment are carried at amortized cost and are reduced by a valuation allowance for estimated credit losses as necessary. Interest on receivables is accreted to income over the life of the receivables using the interest method. The interest method is applied on an individual receivable basis when collectability of the future payments, when due in accordance with the contractual terms of the arrangement, is reasonably assured. Receivables are transferred from held-for-investment to held-for-sale when management no longer intends to hold the receivables for the foreseeable future. Receivables held-for-sale are recorded at the lower of cost or fair value.

As of January 1, 2020, the Partnership revised its measurement of impairment for investment in receivables measured at amortized cost from an incurred loss methodology to an expected loss methodology, in accordance with the adoption of ASU No. 2018-19, Codification Improvements to Topic 326, Financial Instruments – Credit Losses. The measurement of expected credit losses under the current expected credit loss model is based on relevant information including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amounts. As a result, the Partnership recognized $0.1 million as a cumulative adjustment to retained earnings and as a reduction to investment in receivables.

Prior to January 1, 2020, receivables were placed on non-accrual status when management determined that the collectability of contractual amounts were not reasonably assured. While on non-accrual status, receivables were either accounted for on a cash basis, in which income is recognized only upon receipt of cash, or on a cost-recovery basis, where cash receipts reduced the carrying value of the receivable, based on management’s expectation of future collectability. Allowances were established for receivables based upon an estimate of probable losses on an individual receivable by receivable basis if they were determined to be impaired. Receivables were impaired when it was deemed probable that the Partnership would be unable to collect all amounts when due in accordance with the contractual terms of the loan. An allowance is based upon the Partnership’s assessment of the borrower’s overall financial condition, economic resources, payment record, the prospects for support from any financially responsible guarantors and, if appropriate, the net realizable value of any collateral. These estimates consider all available evidence including the expected future cash flows discounted at the receivable’s effective interest rate, fair value of collateral, general economic conditions and trends, historical and industry loss experience and other relevant factors, as appropriate.

In 2018 and 2019, the Partnership assessed investments in receivables for impairment. Internally generated cash flow projections were used to determine if the receivables were expected to be repaid in accordance with the terms of the related agreements. If it was probable that a receivable would not be repaid in accordance with the related agreement, the receivable was deemed impaired. To measure impairment, the present value of the expected future cash flows discounted was calculated using the original effective interest rate. If the present value was less than the carrying value of the receivable, a specific impairment reserve is recorded for the difference. For the year ended December 31, 2018, the Partnership impaired 16 of its investments in receivables and recognized impairment charges totaling $0.8 million. The investments in receivables were impaired to their net realizable value. There was no impairment of investments in receivables during the year ended December 31, 2019.

Investment in Unconsolidated Joint Venture

Investment in Unconsolidated Joint Venture

The Partnership accounts for its investment in an unconsolidated joint venture using the equity method of accounting. Under the equity method, the investment is initially recorded at fair value and subsequently adjusted for distributions and the Partnership’s proportionate share of equity in the joint venture’s income (loss). The Partnership recognizes its proportionate share of the ongoing income or loss of the unconsolidated joint venture as equity income (loss) from unconsolidated joint venture on the consolidated statements of operations. On a quarterly basis, the Partnership evaluates its investment in an unconsolidated joint venture for other-than-temporary impairments. The Partnership elected as an accounting policy to reflect unconsolidated joint venture distributions in the consolidated statements of cash flows using the nature of the distribution approach. Accordingly, the net proceeds were classified as return on investment in unconsolidated joint venture within the operating activities section of the consolidated statements of cash flows for the year ended December 31, 2020 and 2019.

Discontinued Operations

Discontinued Operations

If the disposition of a component, being an operating or reportable segment, business unit, subsidiary or asset group, represents a strategic shift that has or will have a major effect on the Partnership’s operations and financial results, the operating profits or losses of the component disposed of by sale or when classified as held for sale, and the gain or loss upon disposition of the component, are presented as discontinued operations in the statements of operations.

On June 17, 2020, the Partnership completed the sale of its interest in the consolidated joint venture that holds its European outdoor advertising portfolio for a purchase price of £95 million. As a result, the sale of the European outdoor advertising portfolio represents a strategic shift that will have a major effect on the Partnership’s operations and financial results and has met the criteria as discontinued operations in June 2020. Accordingly, for all prior periods presented, the related assets and liabilities, including borrowings under the revolving credit facility and an interest rate swap agreement denominated in British pound sterling (“GBP”), are presented as assets and liabilities held for sale on the consolidated balance sheets (Note 4) and the related operating results, including interest expense and unrealized loss on the interest rate swap agreement denominated in GBP, are presented as income from discontinued operations on the consolidated statement of operations (Note 9).

Deferred Loan Costs

Deferred Loan Costs

Costs incurred associated with the revolving credit facility are capitalized as deferred loan costs and are included in deferred loan costs, net in the consolidated balance sheets in accordance with ASU 2015-15, Interest – Imputation of Interest (Subtopic 835-30): Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements. Costs incurred in obtaining the secured debt facilities are deducted from the carrying amount of the debt liabilities and deferred loan costs are amortized to interest expense over the life of the related loan. When facilities are amended and restated that result in an of extinguishment of debt, any unamortized deferred loan costs, as well as charges incurred for the termination, are recorded to interest expense in the period of the amendment and restatement.

Revenue Recognition

Revenue Recognition

The Partnership recognizes rental income under operating leases, including rental abatements, lease incentives and contractual fixed increases, if any, from tenants under lease arrangements with minimum fixed and determinable increases on a straight-line basis over the non-cancellable term of the related leases when collectability is reasonably assured. The excess of rents recognized over amounts contractually due pursuant to the underlying leases are recorded as deferred rent assets. The excess of rent payments collected over amounts recognized contractually due pursuant to the underlying lease are recorded as prepaid rents. The Partnership accounts for and presents tenant reimbursements as a component of rental revenue in our consolidated income statements in accordance with the new lease standard (“ASC 842”). Tenant reimbursements are recognized as revenue in the period during which the applicable expenses are incurred and the tenant’s obligation to reimburse us arises.

For the years ended December 31, 2020, 2019, and 2018, leases obtained by the Partnership through its acquisition and ownership of real property interests in the wireless communication industry and the outdoor advertising industry were generally cancelable upon 30 - 180 days’ notice by the tenants with no significant penalty. The Partnership evaluates whether the lease arrangements economically compel the tenant to not cancel the lease in determining the term of the lease by considering various factors such as cancellation rights, availability of alternative sites, and historical cancellation rates. For cancellable leases where the tenant is not economically compelled to continue the lease, the term of the lease is considered to be the non-cancellable period with rental abatements and contractual fixed rate increases recorded in the period the amounts become due and payable. Leases obtained through development projects, are generally non‑cancellable for the initial term.

• Wireless Communication – As a result of various factors, including the cancellation rights, ability to find alternative sites, credit risk, and historical cancellation and lease amendment rates, the lease term is generally considered to be the non-cancellable term of the lease of 30 to 180 days. For these leases, rental abatements and contractual fixed increases are recorded in the period the amounts become due and payable.

• Digital Infrastructure – The lease term is generally non-cancellable.

• Outdoor Advertising and Renewable Power Generation – The lease term is generally considered to be the non-cancellable term of the remaining portion of the existing term of the lease.

The capitalized above-market and below-market lease values are amortized as a decrease or increase, respectively, to rental income over the estimated period the tenant is expected to be leasing the site.

Certain leases provide for the greater of a minimum rent or a percentage of the revenue generated by the tenant (“Contingent Rent”). Contingent Rent is recognized when measurable and all possible contingencies have been eliminated. During the years ended December 31, 2020, 2019, and 2018, the Partnership recognized $1.4 million, $1.6 million and $1.2 million of Contingent Rent, respectively.

Rents Receivable, net

Rents Receivable, net

Rents receivables consists of tenant receivables arising in the normal course of business. Tenant receivables are uncollateralized customer obligations requiring payment within various time frames not to exceed one year from the invoice date. If the Partnership determines that collectability of lease payments is not probable, the rent receivable balance is written off and recognized as a decrease in revenue in that period and future revenue recognition is limited to amounts contractually owed and paid.

Income Taxes

Income Taxes

The Partnership is generally not subject to federal, state or local income taxes, except for our subsidiary Landmark Infrastructure Asset OpCo LLC (“Asset OpCo”) and our foreign subsidiaries. Each limited partner is responsible for the tax liability, if any, related to its proportionate share of the Partnerships’ taxable income or loss. Asset OpCo conducts certain activities that may not generate qualifying income and will be treated as a corporation for U.S. federal income tax purposes. Asset OpCo and certain consolidated foreign subsidiaries of the Partnership conduct certain activities in international locations that generate taxable income and will be treated as taxable entities. Additionally, our consolidated REIT subsidiary, Landmark Infrastructure Inc., a Delaware corporation, files as a corporation for U.S. federal income tax purposes. The REIT Subsidiary has elected to be treated as a REIT and we believe that it has operated in a manner that has allowed the REIT Subsidiary to qualify as a REIT for federal income tax purposes, and the REIT Subsidiary intends to continue operating in such manner. If the REIT Subsidiary fails to qualify as a REIT in any taxable year, and is unable to avail itself of certain savings provisions, all of its taxable income would be subject to federal income tax at regular corporate rates. The Partnership may also be subject to various non-income taxes, filing fees, and franchise taxes in various states that are reflected in operating expenses. The Partnership follows the requirements of ASC Topic 740, Income Taxes (“ASC 740”), relating to uncertain tax positions. Based on its evaluation under ASC 740, the Partnership has concluded that there are no significant uncertain tax positions requiring recognition in the consolidated financial statements, nor has the Partnership been assessed interest or penalties by any major tax jurisdictions.

Foreign Currency Translation and Transactions

Foreign Currency Translation

Assets and liabilities denominated in foreign currencies that are translated into U.S. dollars use exchange rates in effect at the end of the period, and revenues and expenses denominated in foreign currencies that are translated into U.S. dollars use average rates of exchange in effect during the related period. Gains and losses resulting from translation adjustments are included in accumulated other comprehensive income (loss).

Foreign Currency Transactions

Transactions denominated in a currency other than U.S. dollars are recorded upon initial recognition at the exchange rate on the date of the transaction. After initial recognition, monetary assets and liabilities denominated in a foreign currency are remeasured at each reporting date into the functional currency at the exchange rate on that date. For all periods presented, the foreign currency interest rate swap agreement and a debt agreement that resulted in mark to market foreign currency transaction adjustments were reclassified to discontinued operations.  

Risk Management

Risk Management

The Partnership is subject to risks incidental to the ownership and investment in real property interests. These risks and uncertainties include the competitive environment in which the Partnership operates – local, regional, and national economic conditions, including consumer confidence, employment rates, and the availability of capital; uncertainties and fluctuations in capital and securities markets; the cyclical and competitive nature of the real estate industry; changes in tax laws and their interpretation; legal proceedings; effect of restrictive covenants in the loan agreements; and the effects of governmental regulation.

In the normal course of business, the Partnership encounters economic risk, including interest rate risk, currency risk, credit risk, and market risk. Interest rate risk is the result of movements in the underlying variable component of financing rates. Credit risk is the risk of default that results from an underlying tenant/borrower’s inability or unwillingness to make contractually required payments. Market risk reflects changes in the valuation of real property interests and investments in receivables held by the Partnership.

Concentration of Credit Risk

Concentration of Credit Risk

The Partnership’s credit risk relates primarily to rent receivables, investments in receivables, cash and interest rate swap agreements. Cash accounts at each U.S. institution are insured by the Federal Deposit Insurance Corporation up to $250,000. The Partnership has not experienced any losses to date on invested cash.

Credit risk associated with interest rate swap agreements arises from the potential failure of counterparties to perform in accordance with the terms of their contracts. The Partnership’s risk management policies define parameters of acceptable market risk and limit exposure to credit risk. Credit exposure resulting from derivative financial instruments is considered in their fair value amounts, among other factors such as the potential adverse position exposure arising from changes over time in interest rates, maturities, and other relevant factors. The Partnership does not anticipate nonperformance by any of its counterparties.

The Partnership’s real property interests are primarily located throughout the United States. The ability of the tenants to honor the terms of their respective leases is dependent upon the economic, regulatory, and social factors affecting the communities in which the tenants operate. In certain instances, the Partnership’s position in the real property interest may be subordinate to a mortgage lender on the real property.

Business Segments

Business Segments

The Financial Accounting Standards Board (“FASB”) accounting guidance with regard to disclosures about segments of an enterprise and related information establishes standards for the manner in which public business enterprises report information about operating segments. The Partnership has four reportable segments, wireless communication, digital infrastructure, outdoor advertising and renewable power generation for all periods presented.

Recently Issued Accounting Standards

Recently Issued Accounting Standards

Changes to GAAP are established by the FASB in the form of Accounting Standards Updates (“ASUs”) to the FASB’s Accounting Standard Codification. The Partnership considers the applicability and impact of all ASUs. Newly issued ASUs not listed below are expected to not have any material impact on its combined financial position and results of operations because either the ASU is not applicable or the impact is expected to be immaterial.

In April 2020, the FASB issued a question and answer document (the “Lease Modification Q&A”) focused on the application of lease accounting guidance to lease concessions provided as a result of the COVID-19 pandemic. Under existing GAAP, the Partnership would have to determine, on a lease by lease basis, if a lease concession was the result of a new arrangement reached with the tenant (treated within the lease modification accounting framework) or if a lease concession was under the enforceable rights and obligations within the existing lease agreement (precluded from applying the lease modification accounting framework). The Lease Modification Q&A allows the Partnership, if certain criteria have been met, to bypass the lease by lease analysis, and instead elect to either apply the lease modification accounting framework or not, with such election applied consistently to leases with similar characteristics and similar circumstances. The Partnership has elected to apply such relief and will avail itself of the election to avoid performing a lease by lease analysis and not apply the lease modification accounting framework. The Lease Modification Q&A had no material impact on the Partnership’s consolidated financial statements.

In June 2016, the FASB issued ASU No. 2016-13, Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), which establishes ASC 326, Financial Instruments – Credit Losses. The ASU revises the measurement of impairment for certain financial instruments measured at amortized cost from an incurred loss methodology to an expected loss methodology. The ASU affects trade receivables, debt securities, net investment in leases, and most other financial assets that represent a right to receive cash. This update is effective for annual and interim financial statement periods beginning after December 15, 2019, with early adoption permitted for financial statement periods beginning after December 15, 2018. In November 2018, the FASB issued ASU No. 2018-19, Codification Improvements to Topic 326, Financial Instruments – Credit Losses. This ASU clarifies that receivables from operating leases are accounted for using the lease guidance and not as financial instruments. The measurement of expected credit losses under the current expected credit loss model is based on relevant information including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amounts. The Partnership adopted the guidance as of January 1, 2020 and recognized $0.1 million as a cumulative adjustment to retained earnings and as a reduction to investments in receivables as of the effective date.

Schedule of Debt Service Coverage Ratio

Certain information with respect to the 2019 and 2017 Securitization is set forth below. The debt service coverage ratio (“DSCR”) is generally calculated as the ratio of annualized net cash flow (as defined in the applicable indenture) to the amount of interest, servicing fees and trustee fees required to be paid over the succeeding 12 months on the principal amount of the Secured Notes, as applicable, that will be outstanding on the payment date following such date of determination.

			Conditions Limiting Distributions of Excess Cash
	Issuer or Borrower	Notes Issued	Cash Trap DSCR	Amortization Period
2019 Securitization	LMRK Issuer Co. LLC, 2019-1 TRS LLC	Series A Senior Secured Notes	1.30x (1)	(1)
2017 Securitization	LMRK Issuer Co. 2 LLC	Series 2017-1 Secured Notes, Class A and Class B	1.30x (2)	(3)

(1) An amortization period will commence (at the option of the related noteholder) if the debt service coverage ratio (measured for the most recently ended period of 12 consecutive months) falls below 1.30 to 1.00 on such calculation date. During an amortization period, excess cash flow will be applied to repay the applicable notes.

(2) Once triggered, a Cash Trap DSCR condition continues to exist until the DSCR exceeds the Cash Trap DSCR for two consecutive calendar months. During a Cash Trap DSCR condition, all cash flow in excess of amounts required to make debt service payments, to fund required reserves, to pay management fees and budgeted operating expenses and to make other payments required under the indenture, referred to as excess cash flow, will be deposited into a reserve account instead of being released to the applicable issuer.

(3) An amortization period commences if the DSCR is equal to or below 1.15x (the “Minimum DSCR”) at the end of any calendar month and continues to exist until the DSCR exceeds the Minimum DSCR for two consecutive calendar months.

Schedule of Secured Notes Annual Principal Payment Amounts Due

The Secured Notes’ annual principal payment amounts due as of December 31, 2020, are as follows (in thousands):

For purposes of determining net income per common unit, the amount otherwise due to the general partner has been referenced as a deemed distribution.

Diluted(1)(2)	$	0.65		$	0.33		$	3.97		$	(0.78	)

(1) Diluted earnings per unit takes into account the potential dilutive effect of common units that could be issued by the Partnership in conjunction with the Series C Preferred Units conversion features. Potential common unit equivalents are anti-dilutive for the years ended December 31, 2020 and 2019 and, as a result, have been excluded in the determination of diluted income (loss) from continuing operations per common unit and net income (loss) per common unit. Potential common unit equivalents were dilutive for the year ended December 31, 2018 and, as a result, have been included in the determination of diluted income (loss) from continuing operations per common and subordinated unit and net income (loss) per common and subordinated unit.

(2) The Partnership Agreement provides that when the subordination period ends, each outstanding subordinated unit will convert into one Common Unit and will thereafter participate pro rata with the other Common Units in distributions of available cash. Effective February 15, 2018, all of the subordinated units, which were owned by Landmark, were converted on a one-for-one basis into Common Units. The diluted effect of Landmark’s subordinated units is reflected using the “if-converted method” which assumes conversion of the subordinated units into Common Units and excludes the subordinated distributions from the calculation, as the “if-converted method” is more dilutive.

[1] An amortization period will commence (at the option of the related noteholder) if the debt service coverage ratio (measured for the most recently ended period of 12 consecutive months) falls below 1.30 to 1.00 on such calculation date. During an amortization period, excess cash flow will be applied to repay the applicable notes.

[2] Once triggered, a Cash Trap DSCR condition continues to exist until the DSCR exceeds the Cash Trap DSCR for two consecutive calendar months. During a Cash Trap DSCR condition, all cash flow in excess of amounts required to make debt service payments, to fund required reserves, to pay management fees and budgeted operating expenses and to make other payments required under the indenture, referred to as excess cash flow, will be deposited into a reserve account instead of being released to the applicable issuer.
