Portions of the Proxy Statement for the registrant’s 2017 Annual Meeting of Stockholders are incorporated herein by reference in Part III of this Annual Report on Form 10-K to the extent stated herein.

Unless otherwise indicated, the terms “Mobile Mini,” the “Company,” “we,” “us” and “our” refer to Mobile Mini, Inc. together with its consolidated subsidiaries.

Our discussion and analysis in this Annual Report on Form 10-K, our 2016 Annual Report to Stockholders, our other reports that we file with the Securities and Exchange Commission (the “SEC”), our press releases and in public statements of our officers and corporate spokespersons contain “forward-looking” statements within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the Private Securities Litigation Reform Act of 1995. Forward-looking statements give our current expectations or forecasts of future events. You can identify these statements by the fact that they do not relate strictly to historical or current events. We have tried, wherever possible, to identify such statements by using words such as “may,” “plan,” “seek,” “will,” “expect,” “intend,” “estimate,” “anticipate,” “believe,” “continue,” “project,” “should,” “likely,” “future,” “target,” “forecast,” “goal,” “observe,” and “strategy” or the negative thereof or variations thereon or similar terminology. The forward-looking statements in this Annual Report on Form 10-K reflect management’s beliefs, plans, objectives, goals, expectations, anticipations and intentions with respect to our financial condition, results of operations, future performance and business, and include statements regarding, among other things, our future actions; financial position; management forecasts; efficiencies; cost savings, synergies and opportunities to increase productivity and profitability; our plans and expectations regarding acquisitions; income and margins; liquidity; anticipated growth; the economy; business strategy; budgets; projected costs and plans and objectives of management for future operations; sales efforts; taxes; refinancing of existing debt; and the outcome of contingencies such as legal proceedings and financial results.

Forward-looking statements are neither historical facts nor assurances of future performance. Instead, they are based only on our current beliefs, expectations and assumptions regarding the future of our business, future plans and strategies, projections, anticipated events and trends, the economy and other future conditions. Because forward-looking statements relate to the future, they are subject to certain risks and uncertainties, including, without limitation, an economic slowdown in the U.S. and/or the U.K. that affects any significant portion of our customer base, or the geographic regions where we operate in those countries; our ability to manage growth at existing or new locations; our ability to obtain borrowings under our revolving credit facility or additional debt or equity financings on acceptable terms; changes in the supply and price of used containers; our ability to increase revenue and control operating costs; our ability to raise or maintain rental rates; our ability to leverage and protect our information technology systems; our ability to protect our patents and other intellectual property; currency exchange and interest rate fluctuations; oil and gas prices; governmental laws and regulations affecting domestic and foreign operations, including tax obligations and labor laws; changes in the supply and cost of the raw materials we use in refurbishing or remanufacturing storage units; competitive developments affecting our industry, including pricing pressures; the timing, effectiveness and number of new markets we enter; our ability to cross-sell our portable storage and specialty containment products; our ability to integrate recent acquisitions; our ability to achieve the expected benefits of the divestiture of the wood mobile offices; our ability to develop a new scalable enterprise resource platform; changes in generally accepted accounting principles; changes in local zoning laws affecting either our ability to operate in certain areas or our customer’s ability to use our products; any changes in business, political and economic conditions due to the threat of future terrorist activity in the U.S. and other parts of the world and related U.S. military action overseas; our ability to utilize our deferred tax assets; and those other risks and uncertainties discussed herein, that could cause actual results to differ materially from historical results or those anticipated. In light of these risks and uncertainties, there can be no assurance that the forward-looking information contained in this Annual Report on Form 10-K will in fact transpire or prove to be accurate. Readers are cautioned to consider the specific risk factors described herein and in “Item 1A. Risk Factors” of this Annual Report Form 10-K, and not to place undue reliance on the forward-looking statements contained herein, which speak only as of the date hereof.

The Company undertakes no obligation to update or publicly revise any forward-looking statement whether as a result of new information, future developments or otherwise. All subsequent written or oral forward-looking statements attributable to the Company or persons acting on its behalf are expressly qualified in their entirety by this paragraph. You are advised, however, to consult any further disclosures we make on related subjects in our subsequently filed Form 10-Q and Form 8-K reports and our other filings with the SEC. Also note that we provide a cautionary discussion of risks, uncertainties and possibly inaccurate assumptions relevant to our business under “Item 1A. Risk Factors” of this Annual Report Form 10-K. We note these factors for investors as permitted by the Private Securities Litigation Reform Act of 1995. You should understand it is not possible to predict or identify all such factors.

We believe we are the world’s leading provider of portable storage solutions, and are committed to providing our customers with superior service and access to a high-quality and diverse fleet. Through our wholly owned subsidiary, Evergreen Tank Solutions, Inc. (“ETS”) we are also a leading provider of specialty containment solutions in the United States (“U.S.”). Our mission is to uphold our leadership positions in portable storage solutions to customers throughout North America and the United Kingdom (“U.K.”) and become the provider of choice for specialty containment products in the U.S.

Mobile Mini, founded in 1983, focuses on renting rather than selling our units, with rental revenues representing approximately 94% of our total revenues for the year ended December 31, 2016. We believe this strategy provides us with predictable, recurring revenue. Additionally, our assets have long useful lives, low maintenance and generally maintain their value throughout their useful lives. We also sell new and used units and provide delivery, installation and other ancillary products and value-added services.

This category consists of our container and ground level office product offerings. We offer a wide range of portable storage products in varying lengths and widths with an assortment of differentiated features such as patented locking systems, premium doors, electrical wiring and shelving. Our portable storage units provide secure, accessible storage for a diversified client base of approximately 80,000 customers across various industries, including retail and consumer services, construction, industrial, commercial and governmental. Our customers use these products for a wide variety of storage applications, including retail and manufacturing, inventory, maintenance supplies, construction materials and equipment, documents and records, household goods, and as portable offices.

Our specialty containment products consist primarily of liquid and solid containment units, pumps and filtration equipment. Additionally, we provide an offering to our customers of value-added services designed to enhance the efficiency of managing liquid and solid waste. The client base for our specialty containment products includes customers in specialty industries, including chemical, refinery, oil and natural gas drilling, mining and environmental.

As of December 31, 2016, our network includes 125 portable storage locations, 19 specialty containment locations and 14 combined locations. Included in our portable storage network are 16 locations in the U.K., where we are a leading provider, and two in Canada. Our portable storage fleet consists of approximately 211,300 units, and our specialty containment business has a fleet of approximately 12,100 units. In the discussions below, we generally refer to our business and assets as either “portable storage” or “specialty containment.”

On May 9, 2016, we issued $250.0 million aggregate principal amount of 5.875% senior notes due July 1, 2024 (the “2024 Notes”). The net proceeds from the sale of the 2024 Notes were used to redeem all $200.0 million aggregate principal amount of our outstanding 7.875% senior notes due December 1, 2020 (the “2020 Notes,” and together with the 2024 Notes, the “Senior Notes”), including related fees, interest and costs for both the redemption of the 2020 Notes and issuance of the 2024 Notes, as well as to repay a portion of the indebtedness outstanding under our Amended and Restated ABL Credit Agreement, dated December 14, 2015, with Deutsche Bank AG New York Branch, as administrative agent, and the other lenders party thereto (the “Credit Agreement” or “revolving credit facility”).

On May 15, 2015, we completed the divestiture of our fleet of approximately 9,400 wood mobile office units within our North American portable storage segment for a cash price of $92.0 million, less associated assumed liabilities of approximately $6.8 million. Our business strategy is to invest in high return, low maintenance, long-lived assets. Wood

mobile offices require more maintenance and upkeep than Mobile Mini’s steel containers and steel ground level offices, resulting in lower margins as compared to our other portable storage products, and our specialty containment products.

On December 10, 2014, we completed the acquisition of ETS, which we refer to as the “ETS Acquisition.” ETS operates as a separate subsidiary under the ETS name, as does its wholly owned subsidiary, Water Movers, Inc. (“Water Movers”) which primarily offers specialty pump equipment and related services. Like Mobile Mini, ETS rents long-lived assets with low maintenance requirements. The acquisition expands Mobile Mini’s product lines and provides significant cross-selling and expansion opportunities as well as modest costs synergies. These operations are included in our results of operations for the periods subsequent to the acquisition date of December 10, 2014, which includes the entire twelve-month periods ended December 31, 2016 and 2015.

The storage industry includes two principal sectors, fixed self-storage and portable storage. The fixed self-storage sector consists of permanent structures located away from customer locations to store excess household goods. We do not participate in the fixed self-storage sector.

The portable storage sector, upon which our business focuses, differs from the fixed self-storage sector, as it brings the storage solution to the customer’s location and fulfills the need for secure storage with immediate access to the storage unit. The advantages of portable storage include convenience, immediate accessibility, and lower price. In contrast to the fixed self-storage sector, the portable storage sector is primarily used by businesses. This sector of the storage industry is highly fragmented and remains primarily local in nature. Although there are no published estimates of the size of the portable storage market, we believe the sector is expanding due to the increasing awareness of the advantages of portable storage and that portable storage units are achieving increased market share compared to other portable options because containers provide ground level access, better protection against wind or water damage, higher security and improved aesthetics when compared to certain other portable storage alternatives such as van trailers.

Certain of our portable storage products serve the modular space industry, which includes mobile offices and other modular structures. We offer steel ground level offices either custom designed and manufactured or made from converted ISO (International Organization for Standardization) containers as well as combination steel ground level office/storage units in varying lengths and widths to serve the various requirements of our customers.

In the specialty containment sector services industry, we service different markets. We serve the industrial market, which is comprised mainly of chemical facilities and refineries, (the “downstream” market), and, to a lesser extent, companies engaged in the exploration and production of oil and natural gas (the “upstream” market). Additionally, we serve a diversified group of customers engaged in projects in the construction, pipeline and mining markets. Downstream customers utilize our equipment and services to manage and remove liquid and solid waste generated by ongoing operating activities as well as turn-around projects and large-scale expansion projects, while upstream customers tend to rent steel tanks to store water used in well hydraulic fracturing (“fracing”). Other customers utilize a wide variety of our products differentiated by the type of project in which they are engaged. The liquid and solid containment industry is highly fragmented, consisting principally of local providers, with a handful of regional and national providers.

Approximately 65% of our estimated combined rental revenue during the twelve-month period ended December 31, 2016 was derived from our North American portable storage business, 19% was derived from our specialty containment business in North America and 16% was derived from our U.K. portable storage business. Our business is subject to the general health of the economy and we utilize a variety of general economic indicators to assess market trends and determine the direction of our business.

Based on our assessment, we expect that the majority of our end markets will continue to drive demand for our products in 2017. In particular, construction, which represents approximately 44% of our consolidated rental revenue, is forecasted for continued growth for the next several years. While only 2% of our consolidated rental revenue is generated by upstream oil and gas customers, the oil and gas industry is forecasted to stabilize in the near term, with potential for future growth.

Market Leader. We believe we are the world’s largest provider of portable storage solutions, and a market leader in portable storage and accommodation solutions in the U.K., where we have nearly 100% geographic coverage, and the third largest provider of specialty containment solutions in the U.S.

The Mobile Mini brand name is associated with high quality portable storage products, superior customer service and value-added storage solutions. Similarly, within the markets and sectors served, the ETS brand name is associated with high quality containment products and services, and the Water Movers name is associated with exceptional quality pump and filtration equipment and service. We believe we are one of a few competitors in the U.S. and the U.K. who possess the brand awareness, network of locations, customer relationships and infrastructure to compete on a national and regional basis while maintaining a strong local market presence.

Superior, Differentiated Products and Service. We offer a wide range of products and proprietary features, including features that provide high-levels of security. This product differentiation within the portable storage sector as well as superior service allows us to gain market share and charge premium rental rates.

We also offer a broad range of specialty containment equipment and value-added services, which enables us to meet customers’ ongoing needs throughout the various life cycles of projects unique to the petrochemical and industrial industry. Our comprehensive turnkey solutions to customers’ containment, storage, pumping and filtration needs drives the creation of strong long-term partnerships with our customers.

Sales and Marketing Emphasis. We target a diverse customer base and, unlike most of our competitors, have developed sophisticated sales and marketing programs enabling us to expand market awareness of our products and generate strong organic growth. We have a dedicated commissioned sales team that is provided with our highly customized contact management system and intensive sales training programs. We manage our salespersons’ effectiveness through extensive sales call monitoring, mentoring and training programs. Our digital advertising includes paid and organic search marketing products, industry targeted content, social messaging, and industry and customer partnerships. External market research vendors are an integral part of our sales and marketing approach. Additionally, our Web site includes value-added features such as product video tours, payment capabilities and real time sales inquiries that enable customers to chat live with salespeople.

National Presence with Local Service. We have invested significant capital developing a national network of locations that serve most major metropolitan areas in the U.S. and the U.K. Our nationwide presence allows us to offer our products to larger customers who wish to centralize the procurement of portable storage and specialty containment products on a multi-regional or national basis. We believe we will be able to leverage our national presence and infrastructure in the portable storage U.S. market to facilitate the geographic expansion of our specialty containment business. In the field, our local managers, sales force and drivers develop and maintain critical personal relationships with customers that benefit from our wide selection of products.

Geographic and Customer Diversification. Our network of portable storage locations covers nearly all major markets in both the U.S. and U.K., providing us with a broad geographical reach. Additionally, since portable storage units are used in a multitude of applications, we have established strong relationships with a well-diversified base of portable storage customers, ranging from leading Fortune 500 companies to sole proprietorships. The operation of specialty containment locations concentrated in the Gulf Coast region of the U.S. further diversifies our geographic presence and customer base.

As a combined company, our geographically- and industry-diversified customer base reduces our susceptibility to the effects of economic downturns in any individual market and industry in which we operate.

Customer Service Focus. The portable storage industry is particularly service intensive. To position ourselves to understand our customers’ needs, we have trained our sales force to focus on all aspects of customer service from the sales call onward. We use Salesforce.com® as our Customer Relationship Management (“CRM”) platform to increase our responsiveness to customer inquiries and to efficiently monitor our sales force’s performance. We use a Net Promoter Score (“NPS”) system to measure customer satisfaction and loyalty through real time surveys conducted by a third party. We utilize customer feedback to drive service improvements across the Company, from our field locations to our corporate headquarters, resulting in proven success as evidenced by our best in class NPS score of 82.9% for 2016. We differentiate ourselves by providing security, convenience, product quality, broad product selection and availability, and customer service. We believe our superior customer service drives customer satisfaction and we survey our customers to ensure that we are easy to do business with.

Within the specialty containment industry, we have leveraged our broad range of products and expertise to differentiate ourselves from competitors. ETS offers a full suite of the liquid and solid containment equipment required to execute a comprehensive containment solution that often must meet stringent regulatory and technical requirements. In addition we offer a proprietary, sophisticated technology platform that provides detailed real-time data capture, tracking and customized reporting capabilities. This technology, which may be integrated with customers’ enterprise systems, is a unique customer service tool that enables us to develop strong, long-term relationships with our larger customers. Many of our specialty containment customers are large, blue-chip companies.

Customized Management Information Systems. We continue to make significant investments in the management information systems supporting our operations. Our systems enable us to optimize fleet utilization, control pricing, dispatch and track our trucks, capture detailed customer data, evaluate and approve credit applications, monitor company results, gain efficiencies in internal control compliance, and support our growth by projecting near-term capital needs. Our customized management information systems provide insight into estimating our forward-looking market potential by territory. This enables us to be more proactive and to respond timely to drive specific revenue streams. Field employees and decision makers at all levels have access to real-time information about the business. In addition, we are able to capture relevant customer demographic and usage information, which we use to target new customers within our existing and new markets. These capabilities result in a competitive advantage over smaller, less sophisticated local and regional competitors.

Our strategic goal is to accelerate rental revenue growth and expand our operating margins by leveraging our infrastructure, focusing on higher returning assets and driving continuous improvements in efficiency. To achieve this goal, we intend to continue execution of the following strategies:

Focus on Core Rental Business with Higher Returning Assets. Our rental business provides predictable recurring revenue and high margins. We are constantly evaluating our portfolio of product offerings to ensure our capital is invested in products that provide optimal returns. For example, during 2015 we made the strategic decision to divest our wood mobile offices, which required significantly more resources to repair, rent and prepare for rental than our other products.

Generate Strong Organic Growth. We focus on increasing market penetration and gaining additional revenues from existing customers as well as gaining new customers through sophisticated sales and marketing programs aimed at increasing brand recognition, expanding market awareness of the uses of portable storage and differentiating our superior products from those of our competitors.

Opportunistic Geographic Expansion. We believe we have attractive expansion opportunities in new or underserved markets in North America where we believe demand for portable storage units is underdeveloped. During the three years ending December 31, 2016, we have completed an aggregate of 13 portable storage acquisitions, which has enabled us to enter new markets, as well as establish new customers in existing markets. We expect to continue to execute on opportunistic acquisitions in the future. We also have a proven strategy to enter markets by migrating available fleet to new markets that can be serviced by nearby full-service field locations. From these start-up operational yards, we are able to redeploy existing available fleet, allowing for cost effective new location openings with minimal capital expenditures. We also believe we have the opportunity to geographically expand the markets in which we offer specialty containment products.

Innovative Product Offering. Our wide offering of products with varying features expands the applications and overall market for our portable storage products. Within our specialty containment products, we offer one of the broadest ranges of services and containment equipment in the industry complemented by an assortment of pumps and filtration units designed to allow us to partner with customers through every project stage. We believe that our rental products can continue to generate substantial demand throughout North America and the U.K.

Opportunities for Cross-selling and Expansion. The ETS Acquisition has allowed us to leverage the combination of Mobile Mini’s portable storage national presence with ETS’ specialty containment expertise to grow revenue by providing new products and services to existing Mobile Mini customers, and by expanding the geographic reach of our specialty containment products to serve customers previously outside of ETS’ historic service area. Additionally, our significant presence in downstream markets, particularly in the Gulf Coast region of the U.S, has allowed us to leverage established, long-term specialty containment relationships for their portable storage needs.

Increase Fleet Utilization. We are focused on increasing utilization through improving sales representatives’ productivity and expanding our sales force and increasing the market’s awareness of our products. Increasing utilization will result in higher rental margins and reduce capital expenditure requirements to meet growth.

Drive Profitability of Existing Locations. We have established key performance indicators to optimize profitability at individual locations and incentivize local management teams based on the performance of their branch. We also compare results across locations and regions to identify areas of opportunity for growth or for increased efficiencies.

Continuous Improvement in Our Systems. We have made significant investments in our management information systems supporting our operations and believe these systems give us a competitive advantage. In the second quarter of 2016, we began executing our new SAP® Enterprise Resource Planning (“ERP”) system. This system is a scalable platform to support future growth.

We protect our products and brands through the use of trademarks and patents. In particular, we have patented our proprietary tri-cam locking system, our Container Guard Lock and other continued improvements in our locking technology both in the markets in which we operate, as well as in Europe and China.

We offer customers a wide range of portable storage and office products with an assortment of differentiated features such as patented locking systems, premium and multiple door options and numerous configuration options. Our portable storage units provide secure, accessible storage. Our principal products are listed below:

We offer a broad range of specialty containment equipment and services complemented by an assortment of pumps, filtration units and waste hauling services. In addition, we offer ancillary products for rental and for sale to our customers, such as: hoses, pipes, filters and spill containment. Our principal products and services include those listed below:

We rent containers and equipment that have been in our fleet for various lengths of time at similar rates, without regard to the age of the unit. As such, we have no need for a systematic program to sell rental fleet units as they age. Generally, sales from our fleet occur due to a particular customer need, having fleet in excess of rental demand at a particular location, or damage beyond economical repair for rental purposes.

Third-party appraisals on our rental fleet are required by our lenders on a regular basis. The appraisals typically report no difference in the value of the unit due to the age or length of time it has been in our fleet. These appraisals are used to calculate our available borrowings under the Credit Agreement. Based in part upon our lender’s third-party appraiser who evaluated our fleet as of September 30, 2015, management estimates that the net orderly liquidation appraisal value of December 31, 2016 was approximately $1.1 billion. Our net book value for this fleet as of December 31, 2016 was $950.1 million.

Steel containers have a long useful life with no technical obsolescence. Our steel portable storage containers and steel ground level offices have estimated useful lives of 30 years from the date we build or acquire and remanufacture them, with residual values of 55%. We maintain our steel containers on a regular basis by removing rust, painting them with rust inhibiting paint, plug-welding holes, and occasionally replacing the wooden floor or a rusted steel panel. Repainting the outside of storage units is the most common maintenance item. A properly maintained container is essentially in the same condition as when initially remanufactured.

When purchased new, our steel tanks and stainless steel tank trailers have estimated useful lives of 25 years, dewatering and roll-off boxes have useful lives ranging from 15 to 20 years and our pumps and filtration equipment have estimated lives of 7 years. We do not assume any residual value at the end of the assets’ useful lives. There is a limited secondary market for specialty containment products. We have outlined a stringent quality control and maintenance program to ensure that only equipment of the highest quality is released to the field. Each container undergoes a thorough visual inspection, hydro-testing and ultrasonic thickness testing to identify maintenance requirements. Tank maintenance includes repainting with rust inhibiting paint, replacing interior liners, and repairing valves, gaskets and rails. This periodic maintenance keeps the specialty containers in essentially the same condition as when initially purchased and is designed to maintain the units’ value.

We depreciate our rental fleet using the straight-line method over each unit’s estimated useful life, after the date we place the unit in service, and the units are depreciated down to their estimated residual values, if any. Assets obtained through acquisitions are recorded at their then current fair market value and depreciated to their estimated residual value over each asset’s estimated remaining life.

We purchase used ISO containers from leasing companies, shipping lines and brokers. These containers were originally built to ISO standards and are 8 feet wide, up to 9.5 feet high and 20, 40 or 45 feet long. After acquisition, we remanufacture and modify these ISO containers. Remanufacturing typically involves cleaning, removing rust and dents, repairing floors and sidewalls, painting, adding our signs and further customizing units by adding our proprietary easy opening door system and our patented locking system. Modification typically involves splitting some containers into differing lengths. The capitalized cost for remanufactured units includes the price we paid for the unit, plus the cost of customizing units and freight charges to our location when the unit is first placed in service. For manufactured units, cost includes our manufacturing cost, customization costs and freight charges to our location when the unit is first placed in service. In addition, we also purchase containers that have been manufactured to our specifications and do not require remanufacturing.

We believe we are able to procure ISO containers at competitive prices because of our volume purchasing power. If needed in the manufacturing or remanufacturing process, we purchase raw materials such as steel, vinyl, wood, glass and paint. Typically we do not have long-term contracts with vendors for the supply of any raw materials.

Our senior management analyzes and manages our business as (i) two portable storage solutions business segments: North America and the U.K. and (ii) one specialty containment business segment. To effectively manage this business across different geographic areas, we divide these business segments into smaller management areas we call divisions, regions and locations. Each of our locations, in their respective segment, generally has similar economic characteristics covering all products rented or sold, including similar customer base, sales personnel, advertising, yard facilities, general and administrative costs and field operations management. Further financial information by segment is provided in Note 14 to the accompanying consolidated financial statements.

We locate our field operations in markets with attractive demographics and strong growth prospects. Within each market, we are located in areas that allow for easy delivery of units to our customers over a wide geographic area. In addition, when cost effective, we seek locations that are visible from high traffic roads in order to advertise our products and our name. A typical branch consists of outdoor storage space for units not currently on rent and a small office.

Each branch has a manager who has overall supervisory responsibility for all operational activities. Field location managers report to regional managers who each generally oversee multiple locations. Our regional managers, in turn, report to one of our operational senior vice presidents (called a managing director in the U.K.). Performance-based incentive bonuses are a substantial portion of the compensation for these senior vice presidents, regional managers and field managers.

Locations have dedicated sales staff and transportation personnel that deliver and pick up units from customers. We also supplement our delivery fleet by outsourcing delivery services to independent haulers when appropriate. The locations have delivery trucks and forklifts to load, transport and unload units and a yard staff responsible for unloading and stacking units. Portable storage steel units can be stored by stacking them to maximize usable ground area. Our field locations perform preventive maintenance tasks, but outsource major repairs and other maintenance requirements either externally or to a senior repair team.

We approach the market through a hybrid sales model consisting of a dedicated sales staff at our field locations as well as at our National Sales Center (“NSC”). Our field sales representatives handle local inbound calls and work to develop their branch territory and local relationships through effective networking and sales calls. The NSC handles overflow inbound calls and digital leads from new customers and initiates outbound sales campaigns to new and existing customers not serviced by sales representatives at our local locations. Our entire staff works with our local field managers and dispatchers to ensure customers receive integrated first-class, one-call service from initial call to delivery. We believe that offering local salesperson presence for customers, along with the efficiencies of a centralized sales operation for customers not needing a local sales contact, allows us to provide high levels of customer service and serve all of our customers in a dedicated, efficient manner.

Our sales and marketing personnel provide information about our products to prospective customers by handling inbound calls and initiating outbound marketing calls. We have ongoing sales and marketing training programs covering all aspects of rental and customer service. Our field locations communicate with one another and with corporate headquarters through our ERP system and our CRM platform, Salesforce.com®. This centralization of information enables the sales team to share leads and other information and permits management to monitor and review sales and rental productivity on a location-by-location basis. We improve our sales efforts by recording and rating the sales calls made and received by our trained sales force. Our sales personnel are compensated largely on a commission basis.

Our nationwide presence in the U.S. and the U.K. allows us to offer our products to larger customers who wish to centralize the procurement of portable storage on a multi-regional or national basis. Within our portable storage business, we are well equipped to meet these customers’ needs through our National Account Program, which centralizes and simplifies the procurement, rental and billing process for those customers. Our largest customers tend to participate in our National Account Program. We provide our national account customers with service guarantees, which assure them they will receive the same superior customer service and access to high quality, diverse fleet from any of our field locations. This program has helped us succeed in leveraging customer relationships developed at one location across our entire network of locations.

We focus a significant portion of our marketing expenditures on digital initiatives for both existing and potential customers. We also use targeted direct email and digital programs to build brand awareness by communicating market

specific features and tying them to industry benefits of using portable storage solutions. We have implemented aspects of search engine marketing like remarketing, Pay Per Click, content curation, and organic search best practices to drive our customers to on-line lead generation with real-time access to our CRM platform. Immediately after completion of the online form, our dedicated sales force will make contact with the customer and complete the request. External market research vendors are an integral part of our sales and marketing approach. Additionally, our Web site includes value-added features such as product video tours, payment capabilities and real time sales inquiries that enable customers to chat live with salespeople.

Each specialty containment branch is responsible for targeting potential new customers in the branch’s service area and to be available to respond to customers 24 hours a day, 365 days a year. The branches are supported by a corporate team, including a sales and marketing department, business development representatives and national account management. Branch managers and business development representatives work with customers to design customized solutions and identify new service and product applications. National account management maintains contractual relationships with numerous blue-chip customers and coordinates the provision of services to customers with locations across multiple areas. Our sales personnel are compensated largely on a commission basis.

Within our specialty containment business we utilize an advanced prospect and customer management software package across our sales force and branch network, providing enhanced visibility and tracking on all prospective customer accounts. Personnel have access to real-time critical customer information regardless of location. This access facilitates targeted marketing and sharing of relevant customer information across branches.

In 2016, we served approximately 80,000 customers. Within the portable storage solutions product lines, our first and second largest customers accounted for 3.7% and 0.9%, respectively, of portable storage rental revenues and our 20 largest customers combined accounted for approximately 10.6% of portable storage rental revenues. During 2016, approximately 56% of our customers rented a single unit. We target customers who we believe can benefit from our portable storage solutions, either for seasonal, temporary or long-term storage needs. Customers use our portable storage units for a wide range of purposes.

Our specialty containment customers are concentrated in the Gulf Coast region of the U.S. and are generally large companies, including blue-chip companies, with whom we have long-term relationships. During the year ended December 31, 2016, our first and second largest specialty containment customers accounted for approximately 14.7% and 6.6%, respectively, of specialty containment rental revenues and our 20 largest customers combined accounted for approximately 53.5% of specialty containment rental revenues. Generally, our specialty containment customers belong in one of the following three categories:

We estimate that total 2016 specialty containment rental revenue was 72%, 10% and 18% from downstream, upstream and diversified customers, respectively.

The following table provides an overview of our customers and the estimated portion of total rental revenue generated by each customer group during the year ended December 31, 2016:

We enter into contracts with our portable storage customers based on a monthly rate. The rental continues until cancelled by the customer or the Company. On average, the steel storage containers on rent at December 31, 2016, have been in place for 30 months, and the steel ground level offices on rent at December 31, 2016 have been in place for 14 months. Our rental contracts provide that the customer is responsible for the cost of delivery and pickup and specify that the customer is liable for any damage done to the unit beyond ordinary wear and tear. Customers may purchase a damage waiver from us to avoid damage liability in certain circumstances, which provides us with an additional source of recurring revenue. Customer possessions stored within a portable storage unit are the responsibility of that customer.

Our specialty containment rental contracts typically offer daily, weekly or monthly rates. The rental duration varies widely by application, and the rental continues until the unit is returned in clean condition to us. Rental contracts specify that the customer is responsible for carrying commercial general liability insurance, is liable for any damage to the unit beyond ordinary wear and tear, and for all materials the customer contains in rented equipment. The customer is contractually responsible for the cost of delivery and pickup, as well as thoroughly emptying and cleaning the equipment before return.

In all segments, we face competition from local and regional companies, as well as national companies, in substantially all of our current markets. We compete with several large national and international companies in our ground level office product line. Our competitors include lessors of storage units, mobile offices, van trailers and other structures used for portable storage. We also compete with conventional fixed self-storage facilities. In our portable storage segment, we compete primarily in terms of security, convenience, product quality, broad product selection and availability, rental rates and customer service. In our core portable storage business, our largest competitors are Algeco Scotsman, PODS, Pac-Van,

1‑800-PACK-RAT, Haulaway Storage Containers, ModSpace, McGrath RentCorp, and Wernick Hire, along with other national, regional and local companies. In our specialty containment business we compete based on factors including: quality and breadth of equipment, technical applications expertise, knowledgeable and experienced sales and service personnel, on-time delivery and proactive logistics management, geographic areas serviced, rental rates and customer service. Our competitors include BakerCorp, Rain For Rent and Adler Tanks.

As of December 31, 2016, we employed 1,998 employees, the majority of which are full time. Of these employees, 1,583 are employed in North America and 415 are employed in the U.K. No employees are currently covered by a collective bargaining agreement, and we have never experienced a work stoppage. We believe that our relations with our employees are good.

Demand from our portable storage customers is somewhat seasonal. Construction customers typically reflect higher demand during months with more temperate weather, while demand for our portable storage units by large retailers is stronger from September through December because these retailers need to store more inventories for the holiday season. Our retail customers usually return these rented units to us in December and early in the following year. In the specialty containment business, demand from customers is typically higher in the middle of the year from March to October, driven by the timing of customer maintenance projects. The demand for rental of our pumps may also be impacted by weather, specifically when temperatures drop below freezing.

Our operations, and the operations of certain of our customers, are subject to numerous federal and local laws and regulations governing environmental protection and transportation. These laws regulate such issues as wastewater, storm water and the management, storage and disposal of, or exposure to, hazardous substances. We are not aware of any pending environmental compliance or remediation matters that are reasonably likely to have a material adverse effect on our business, financial position or results of operations. However, failure by us to comply with applicable environmental and other requirements could result in fines, penalties, enforcement actions, third party claims, remediation actions, and could negatively impact our reputation with customers. We have a company-wide focus on safety and have implemented a number of measures to promote workplace safety. Customers are increasingly focused on safety records in their sourcing decisions due to increased regulations to report all incidents that occur at their sites and the costs associated with such incidents.

Our Internet address is www.mobilemini.com. We make available at this address, free of charge, our Annual Report on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K and amendments to those reports filed or furnished pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), as soon as reasonably practicable after we electronically file such material with, or furnish it to, the SEC. In this Form 10-K, we incorporate by reference as identified herein certain information from parts of our proxy statement for the 2017 Annual Meeting of Stockholders, which we will file with the SEC and which will be available free of charge on our Web site. Reports of our executive officers, directors and any other persons required to file securities ownership reports under Section 16(a) of the Exchange Act are also available through our Web site. Information contained on our Web site is not part of this Annual Report on Form 10-K.

Our business, results of operations and financial condition are subject to numerous risks and uncertainties. Set forth below and elsewhere in this Annual Report on Form 10-K and in other documents we file with the SEC are descriptions of the risks and uncertainties that could cause our actual results to differ materially from the results contemplated by the forward-looking statements contained in this Annual Report on Form 10-K. Should any of these risks materialize, our business, results of operations, financial condition and future prospects could be negatively impacted, which in turn could affect the trading value of our securities.

Our operational measures designed to increase revenue while continuing to control operating costs may not generate the improvements and efficiencies we expect and may not drive growth.

We have employed a number of operational measures designed to increase revenue while continuing to pursue our strategy of reducing operating costs where available. Additionally, our hybrid sales strategy of using local sales people in addition to a centralized call center team is designed to meet customer needs and drive revenue growth but differs from our historic sales structure. No assurance can be given that these strategies will achieve the desired goals and efficiencies in the future. The success of these strategies is dependent on a number of factors that are beyond our control.

Even if we carry out these measures in the manner we currently expect, we may not achieve the improvements or efficiencies we anticipate, or on the timetable we anticipate. There may be unforeseen productivity, revenue or other consequences resulting from our strategies that will adversely affect us. Therefore, there can be no guarantee that our strategies will prove effective in achieving desired profitability or margins. Additionally, these strategies may have adverse consequences if our cost cutting and operational changes are deemed by customers to adversely impact product quality or service levels.

We face intense competition that may lead to our inability to increase or maintain our prices, which could have a material adverse impact on our results of operations.

The portable storage and specialty containment industries are highly competitive and highly fragmented. Many of the markets in which we operate are served by numerous competitors, ranging from national companies like ourselves, to smaller multi-regional companies and small, independent businesses with a limited number of locations. See “Business — Competition.” Some of our principal competitors are less leveraged than we are and may have lower fixed costs and may be better able to withstand adverse market conditions within the industry. Additionally, some of our competitors currently offer products outside of our offerings or may have better brand recognition in some end customer sectors. If these competitors use their brand awareness to enter our product offerings, customers may choose these competitors’ products over ours and we could lose business. Our competitors typically compete aggressively on the basis of pricing and may continue to impact our ability to attract and retain customers or maintain the rental rates we charge. Additionally, general economic factors could negatively impact the rental rates we are able to charge. To the extent that we choose to match our competitors’ declining prices, it could harm our results of operations as we would have lower margins. To the extent that we choose not to match or remain within a reasonable competitive distance from our competitors’ pricing, it could also harm our results of operations, as we may lose rental volume.

We may not obtain expected synergies and cost efficiencies with our new ERP system.

We have implemented a new ERP system, which we began executing in stages in April 2016. The ERP system is designed to accurately maintain our books and records and provide information important to the operation of the business to our management team. The implementation of our new ERP system has required, and will continue to require, significant investment of human and financial resources. We have incurred and expect to continue to incur additional expenses related to our implementation as we continue to enhance and develop our ERP system. Many companies have experienced delays and difficulties with the implementation of new or changed ERP systems that have had a negative effect on their business. Any future disruptions, delays or deficiencies in the design and implementation of our ERP system could result in potentially much higher costs than we currently anticipate and could adversely affect our ability to process orders, deliver units, send invoices and track payments, fulfill contractual obligations, file reports with the SEC in a timely manner, and/or otherwise operate our business, or otherwise impact our controls environment. Any of these consequences could have an adverse effect on our results of operations and financial condition.

We rely heavily on information technology in our operations, and any cyber-security issue, material failure, inadequacy, interruption or breach of security of that technology could harm our ability to effectively operate our business.

We rely heavily on information systems across our operations. Our ability to effectively manage our business depends significantly on the reliability and capacity of these systems. In addition, we utilize third-party cloud providers to host certain of our applications and to store data. Like other companies, our information technology systems may be vulnerable to a variety of interruptions due to our own error or events beyond our control, including, but not limited to, cyber-security breaches, interruptions or delays in service from our third-party cloud providers, natural disasters, terrorist attacks, telecommunications failures, computer viruses, hackers, and other security issues. The failure of these systems to operate

effectively, could result in substantial harm or inconvenience to us or our customers. This could include the theft of our intellectual property or trade secrets, or the improper use of personal information or other “identity theft.” Each of these situations or data privacy breaches may cause delays in customer service, reduce efficiency in our operations, require significant capital investments to remediate the problem, or result in negative publicity that could harm our reputation and results.

We intend to continue to launch operations into new geographic markets and/or add specialty containment operations in existing portable storage markets, which may be costly and may not be successful.

We have in the past, and intend in the future, to expand our portable storage and specialty containment operations into new geographic markets, primarily in North America. This expansion could require financial resources that would not therefore be available for other aspects of our business. In addition, this expansion could require the time and attention of management, leaving less time to focus on existing business. If we fail to manage the risks inherent in our geographic expansion, we could incur capital and operating costs without any related increase in revenue, which would harm our operating results.

We may not be able to successfully integrate past acquisitions, or complete and integrate future acquisitions, or greenfield expansions.

Any acquisition or expansion may result in additional and unexpected expenses, and the anticipated benefits of the integration of an acquisition or expansion may not be realized. In addition, we may assume certain liabilities in connection with any acquisition. To the extent there are unrecorded liabilities, including current or future environmental-related costs, which we failed to discover during our due diligence investigations and that are not subject to indemnification or reimbursement, our future operations could be materially and adversely affected.

We may not be able to successfully complete future strategic acquisitions if we cannot reach agreement on acceptable terms or for other reasons. We may have to incur debt or issue equity securities to pay for any future acquisition, the issuance of which could involve the imposition of restrictive covenants or be dilutive to our existing stockholders.

In connection with potential future acquisitions, we may experience difficulty integrating personnel and operations, which could negatively affect our operating results in the following manner:

We are exposed to various possible claims relating to our business and our insurance may not fully protect us.

We are exposed to various possible claims relating to our business. These possible claims include those relating to: (i) personal injury or death caused by products rented or sold by us; (ii) motor vehicle accidents involving our vehicles and our employees; (iii) employment-related claims; (iv) property damage, (v) cyber-security breaches, (vi) shareholder lawsuits, (vii) medical claims exceeding our insurance limits and (viii) commercial claims. Our insurance policies have deductibles or self-insured retentions which would require us to expend amounts prior to taking advantage of coverage limits. Currently, we believe that we have adequate insurance coverage for the protection of our assets and operations. However, our insurance may not fully protect us for certain types of claims, such as claims for punitive damages or for damages arising from intentional misconduct, which are often alleged in third party lawsuits. In addition, we may be exposed to uninsured liability at levels in excess of our policy limits.

If we are found liable for any significant claims that are not covered by insurance, our liquidity and operating results could be materially adversely affected. It is possible that our insurance carrier may disclaim coverage for any class action and derivative lawsuits against us. It is also possible that some or all of the insurance that is currently available to us will not be available in the future on economically reasonable terms or not available at all. In addition, whether we are covered by insurance or not, certain claims may have the potential for negative publicity surrounding such claims, which may lead to lower revenues, as well as additional similar claims being filed.

Unionization by some or all of our employees could cause increases in operating costs.

None of our employees are presently covered by collective bargaining agreements. From time to time various unions attempt to organize certain of our employees. We cannot predict the outcome of any continuing or future efforts to organize our employees, the terms of any future labor agreements, or the effect, if any, those agreements might have on our operations or financial performance.

We believe that a unionized workforce would generally increase our operating costs, divert the attention of management from servicing customers and increase the risk of work stoppages, all of which could have a material adverse effect on our business, results of operations or financial condition.

The supply and cost of used ISO containers fluctuates, which can affect our pricing and our ability to grow.

As needed, we purchase, remanufacture and modify used ISO containers in order to expand our rental fleet. If used ISO container prices increase substantially, these price increases could increase our expenses and reduce our earnings, particularly if we are not able (due to competitive reasons or otherwise) to raise our rental rates to absorb this increased cost. Conversely, an oversupply of used ISO containers may cause container prices to fall. In such event, competitors may then lower the rental rates on their storage units. As a result, we may need to lower our rental rates to remain competitive. These events could cause our revenues and our earnings to decline.

We depend on our suppliers for the specialty containment equipment we rent to customers.

Nearly all the specialty containment equipment we rent to customers is manufactured by a limited number of suppliers, none of with whom we maintain long-term contracts. If our suppliers were unable or unwilling to provide us with such equipment, our operations would be affected if we were unable to obtain the equipment necessary to operate and grow our business. Also, should our suppliers substantially increase their prices (due to increased demand in certain products, or otherwise), we may not be able to raise our rental rates to absorb such increased cost. These events could cause our revenues and earnings to decline.

The supply and cost of raw materials we use in remanufacturing and repairing units fluctuates and could increase our operating costs.

As needed, we remanufacture and repair units for our rental fleet and for sale. In these processes, we purchase steel, paint, glass and other raw materials from various suppliers. We cannot be sure that an adequate supply of these materials will continue to be available on terms acceptable to us. The raw materials we use are subject to price fluctuations that we cannot control. Changes in the cost of raw materials can have a significant effect on our operations and earnings. Rapid increases in raw material prices are often difficult to pass through to customers, particularly to rental customers. If we are unable to pass on these higher costs, our profitability could decline. If raw material prices decline significantly, we may have to write down our raw materials inventory values. If this happens, our results of operations and financial condition could decline.

We may not be able to adequately protect our intellectual property and other proprietary rights that are material to our business.

Our ability to compete effectively depends in part upon protection of our rights in trademarks, copyrights and other intellectual property rights we own or license, including patents to our locking system for our portable storage solutions. Our use of contractual provisions, confidentiality procedures and agreements, and trademark, copyright, unfair competition, trade secret and other laws to protect our intellectual property and other proprietary rights may not be adequate. Litigation may be necessary to enforce our intellectual property rights and protect our proprietary information and patents, or to defend against claims by third parties that our services or our use of intellectual property infringe their intellectual property rights. Any litigation or claims brought by or against us could result in substantial costs and diversion of our resources. A successful claim of trademark, copyright or other intellectual property infringement against us could prevent us from providing services,

which could harm our business, financial condition or results of operations. In addition, a breakdown in our internal policies and procedures may lead to an unintentional disclosure of our proprietary, confidential or material non-public information, which could in turn harm our business, financial condition or results of operations.

If we determine that our goodwill or other intangible assets have become impaired, we may incur significant charges to our pre-tax income.

At December 31, 2016, we had $703.6 million of goodwill and $68.4 million of unamortized intangible assets on our Consolidated Balance Sheet. In the future, goodwill and intangible assets may increase as a result of future acquisitions. Goodwill is reviewed at least annually for impairment. Both goodwill and intangible assets are reviewed for impairment when an impairment indicator is present. Impairment may result from, among other things, deterioration in the performance of the business, adverse market conditions, stock price, and adverse changes in applicable laws or regulations, including changes that restrict the activities of the Company.

For more information, see the “Notes to Consolidated Financial Statements” included in our financial statements contained in this Annual Report on Form 10-K.

If we fail to attract and retain key management and personnel, we may be unable to implement our business plan.

One of the most important factors in our ability to profitably execute our business plan is our ability to attract, develop and retain qualified personnel, including our chief executive officer (“CEO”) and senior operational management. Our success in retaining a CEO and attracting and retaining qualified people, particularly experienced operational and sales management, is dependent on the resources available in individual geographic areas and the impact on the labor supply due to general economic conditions, as well as our ability to provide a competitive compensation package, including the implementation of adequate drivers of retention and rewards based on performance, and work environment. The departure of any key personnel and our inability to enforce non-competition agreements could have a negative impact on our business.

RISKS RELATED TO OUR INDEBTEDNESS, THE ECONOMY, AND GLOBAL CAPITAL AND CREDIT MARKETS

Our business is subject to the general health of the economy, including non-residential spending and energy prices, accordingly any slowdowns or decreases in the U.S. or international economy could materially affect our revenue and operating results.

An economic slowdown in the U.S. or international economy, including non-residential construction spending and energy prices, may cause substantial volatility in the stock market and layoffs and other restrictions on spending by companies in almost every business sector which could impact our business in a variety of ways, including:

Without similar changes in expenses, which may be difficult to achieve, our margins will contract if revenue falls, and ultimately may result in having a material adverse effect on our financial condition.

We operate with a high amount of debt and we may incur significant additional indebtedness.

Our operations are capital intensive, and we operate with a high amount of debt relative to our size. At December 31, 2016, we had $250.0 million in aggregate principal amount of the 2024 Notes and $641.2 million of indebtedness under the Credit Agreement. Our substantial indebtedness could have adverse consequences. For example, it could:

Covenants in our debt instruments restrict or prohibit our ability to engage in or enter into a variety of transactions.

Our Credit Agreement requires us, under certain limited circumstances, to maintain certain financial ratios and limits our ability to make capital expenditures. These covenants and ratios could have an adverse effect on our business by limiting our ability to take advantage of financing, merger and acquisition or other corporate opportunities and to fund our operations. Breach of a covenant in our debt instruments could cause acceleration of a significant portion of our outstanding indebtedness. Any future debt could also contain financial and other covenants more restrictive than those imposed under the indenture governing the 2024 Notes, and the Credit Agreement.

The indenture governing the 2024 Notes contains various covenants that limit our discretion in operating our business. In particular, we are limited in our ability to merge, consolidate or transfer substantially all of our assets, issue preferred stock of subsidiaries and create liens on our assets to secure debt. In addition, if there is a default, and we do not maintain borrowing availability in excess of certain pre-determined levels, we may be unable to incur additional indebtedness, make restricted payments (including paying cash dividends on our capital stock) and redeem or repurchase our capital stock. The 2024 Notes do not contain financial maintenance covenants and the financial maintenance covenant under the Credit Agreement is not applicable unless we fall below specific borrowing availability levels.

A breach of a covenant or other provision in any debt instrument governing our current or future indebtedness could result in a default under that instrument and, due to cross-default and cross-acceleration provisions, could result in a default under our other debt instruments. Upon the occurrence of an event of default under the Credit Agreement or any other debt instrument, the lenders could elect to declare all amounts outstanding to be immediately due and payable and terminate all commitments to extend further credit. If we were unable to repay those amounts, the lenders could proceed against the collateral granted to them, if any, to secure the indebtedness. If the lenders under our current or future indebtedness accelerate the payment of the indebtedness, we cannot assure you that our assets or cash flow would be sufficient to repay in full our outstanding indebtedness, including the 2024 Notes.

The amount we can borrow under our Credit Agreement depends in part on the value of our rental fleet. If the value of our rental fleet declines under appraisals our lenders receive, the amount we can borrow will similarly decline. We are required to satisfy several covenants with our lenders that are affected by changes in the value of our rental fleet. We would be in breach of certain of these covenants if the value of our rental fleet drops below specified levels. If this happens, we may not be able to borrow the amounts we need to expand our business, and we may be forced to liquidate a portion of our existing fleet.

We may not be able to generate sufficient cash to service all of our debt, and may be forced to take other actions to satisfy our obligations under such indebtedness, which may not be successful.

Our ability to make scheduled payments on or to refinance our obligations under our debt will depend on our financial and operating performance and that of our subsidiaries, which, in turn, will be subject to prevailing economic and competitive conditions and to financial and business factors, many of which may be beyond our control. See the table under “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Liquidity and Capital Resources — Contractual Obligations” for disclosure regarding the amount of cash required to service our debt.

We may not maintain a level of cash flow from operating activities sufficient to permit us to pay the principal, premium, if any, and interest on our indebtedness. If our cash flow and capital resources are insufficient to fund our debt service obligations, we may be forced to reduce or delay capital expenditures, sell assets, seek to obtain additional equity capital or restructure our debt. Such alternative measures may not be successful and may not enable us to meet our scheduled debt service obligations. We may not be able to refinance any of our indebtedness or obtain additional financing, particularly

because of our anticipated high levels of debt and the debt incurrence restrictions imposed by the agreements governing our debt, as well as prevailing market conditions. In the absence of such operating results and resources, we could face substantial liquidity problems and might be required to dispose of material assets or operations to meet our debt service and other obligations. The instruments governing our indebtedness restrict our ability to dispose of assets and use the proceeds from any such dispositions. We may not be able to consummate those sales, or if we do, at an opportune time, or the proceeds that we realize may not be adequate to meet debt service obligations when due.

Fluctuations between the British pound and U.S. dollar could adversely affect our results of operations.

We derived approximately 16% of our total revenues in 2016 from our operations in the U.K. The financial position and results of operations of our U.K. subsidiaries are measured using the British pound as the functional currency. As a result, we are exposed to currency fluctuations both in receiving cash from our U.K. operations and in translating our financial results back into U.S. dollars. We believe the impact on us of currency fluctuations from an operations perspective is mitigated by the fact that the majority of our expenses, capital expenditures and revenues in the U.K. are in British pounds. We do, however, have significant currency exposure as a result of translating our financial results from British pounds into U.S. dollars for purposes of financial reporting. Assets and liabilities of our U.K. subsidiaries are translated at the period-end exchange rate in effect at each balance sheet date. Our income statement accounts are translated at the average rate of exchange prevailing during each month. Translation adjustments arising from differences in exchange rates from period to period are included in accumulated other comprehensive loss in stockholders’ equity.

A strengthening of the U.S. dollar against the British pound reduces the amount of income or loss we recognize on a consolidated basis from our U.K. business. We cannot predict the effects of further exchange rate fluctuations on our future operating results. We are also exposed to additional currency transaction risk when our U.S. operations incur purchase obligations in a currency other than in U.S. dollars and our U.K. operations incur purchase obligations in a currency other than in British pounds. As exchange rates vary, our results of operations and profitability may be harmed. We do not currently hedge our currency transaction or translation exposure, nor do we have any current plans to do so. The risks we face in foreign currency transactions and translation may continue to increase as we further develop and expand our U.K. operations. Furthermore, to the extent we expand our business into other countries, we anticipate we will face similar market risks related to foreign currency translation caused by exchange rate fluctuations between the U.S. dollar and the currencies of those countries.

Global capital and credit market conditions could have an adverse effect on our ability to access the capital and credit markets, including our revolving credit facility.

Disruptions in the global credit markets that materially impact liquidity in the debt market, making financing terms for borrowers less attractive or, in some cases, unavailable altogether, have occurred in the past and may occur again in the future. Such a disruption could result in the unavailability of certain types of debt financing, including access to revolving lines of credit. We engage in borrowing and repayment activities under our revolving credit facility on an almost daily basis and have not had any disruption in our ability to access our revolving credit facility as needed. However, future credit market conditions could increase the likelihood that one or more of our lenders may be unable to honor its commitments under our revolving credit facility, which could have an adverse effect on our business, financial condition and results of operations.

Additionally, in the future we may need to raise additional funds to, among other things, fund our existing operations, improve or expand our operations, respond to competitive pressures, or make acquisitions. If adequate funds are not available on acceptable terms, we may be unable to meet our business or strategic objectives or compete effectively. If we raise additional funds by issuing equity securities, stockholders may experience dilution of their ownership interests, and the newly issued securities may have rights superior to those of the common stock. If we raise additional funds by issuing debt, we may be subject to further limitations on our operations arising out of the agreements governing such debt. If we fail to raise capital when needed, our business will be negatively affected.

As Department of Transportation regulations change, our operations could be negatively impacted and competition for qualified drivers could increase.

We operate in the U.S. pursuant to operating authority granted by the U.S. Department of Transportation (“DOT”). Our Company drivers must comply with the safety and fitness regulations of the DOT, including those relating to drug and alcohol testing and hours-of-service. Such matters as equipment weight and dimensions also are subject to government regulations. Our safety record could be ranked poorly compared to our peer firms. A poor fleet ranking may result in the loss

of customers or difficulty attracting and retaining qualified drivers which could affect our results of operations. Should additional rules be enacted in the future, compliance with such rules could result in additional costs.

We are subject to environmental regulations and could incur costs relating to environmental matters.

Federal, state, local, foreign and provincial laws and regulations regulate such issues as wastewater, storm water, air quality and the management, storage and disposal of, or exposure to, hazardous substances and hazardous and solid wastes. Several aspects of our businesses may involve risks related to environmental and health and safety liability. For example, we own, transport and rent tanks and boxes in which waste materials are placed by our customers. While we have a policy which, with certain limited exceptions, requires customers to return tanks and containers clean of any substances, they may fail to comply with these obligations. Additionally, we provide waste hauling services, which involves environmental risks during transport. While we endeavor to comply with all regulatory requirements, failure to be in compliance with any environmental regulatory requirements may increase our compliance or remediation costs or cause restrictions on our business, either of which could have a material effect on our financial position or results of operations.

We are also required to obtain environmental permits from governmental authorities for certain of our operations. If we violate or fail to obtain or comply with these laws, regulations, or permits, we could be fined or otherwise sanctioned by regulators. We could also become liable if employees or other parties are improperly exposed to hazardous materials.

Under certain environmental laws, we could be held responsible for all of the costs relating to any contamination at, or migration to or from, our or our predecessors’ past or present facilities. These laws often impose liability even if the owner, operator or lessor did not know of, or was not responsible for, the release of such hazardous substances.

Environmental laws are complex, change frequently, and have tended to become more stringent over time. The costs of complying with current and future environmental and health and safety laws, and our liabilities arising from past or future releases of, or exposure to, hazardous substances, may adversely affect our business, results of operations, or financial condition.

Ongoing governmental review of hydraulic fracturing (“fracing”) and its environmental impact could lead to changes to this activity or its substantial curtailment, which could adversely affect our revenue and results of operations.

Approximately 10% of our specialty containment rental revenue for the year ended December 31, 2016 is related to customers involved in the upstream exploration and production of oil and natural gas. A portion of this revenue involves rentals to customers that use the fracing method to extract natural gas. The Environmental Protection Agency is studying the potential adverse effects that fracing may have on the environment and public health, and has issued regulations or guidance regarding certain aspects of the process. Other federal, state and local governments and governmental agencies have also begun to investigate and/or regulate fracing. Additional governmental regulation could result in increased costs of compliance or the curtailment of fracing in the future, which would adversely affect our revenue and results of operations.

Some zoning laws and building codes in the U.S. and Canada and temporary planning permission regulations in the U.K. restrict the use of our portable storage and office units and therefore limit our ability to offer our products in all markets.

Most of our customers use our storage units to store their goods on their own properties for various lengths of time. Local zoning laws and temporary planning permission regulations in some of our markets do not allow some of our customers to keep portable storage and office units on their properties or do not permit portable storage units unless located out of sight from the street or may limit the type of product they may use or how long it can be at their locations. Local building codes may place restrictions on our office units. If local zoning laws or planning permission regulations in one or more of our markets no longer allow our units to be stored on customers’ sites, our business in that market will suffer.

We face unique regulatory and political challenges presented by international markets.

In connection with our business outside the U.S., we face exposure to additional regulatory requirements, including certain trade barriers, unforeseen risks related to foreign trade, tariffs and embargos, changes in political and economic conditions, and exposure to additional and potentially adverse tax regimes. Our success in the U.K. depends, in part, on our ability to anticipate and effectively manage these and other risks. Our failure to manage these risks may adversely affect our growth, in the U.K. and elsewhere, and lead to increased administrative costs.

In June 2016, the U.K. held a referendum in which British citizens approved an exit from the European Union (the “E.U.”), which is commonly referred to as “Brexit”. As a result of the referendum, it is expected that the British government will begin negotiating the terms of the U.K.’s withdrawal from the E.U. A withdrawal could, among other outcomes, disrupt the free movement of goods, services and people between the U.K. and the E.U., undermine bilateral cooperation in key policy areas and significantly disrupt trade between the U.K. and the E.U. In addition, Brexit could lead to legal uncertainty and potentially divergent national laws and regulations as the U.K. determines which E.U. laws to replace or replicate. Given the lack of comparable precedent, it is unclear what financial, trade and legal implications the withdrawal of the U.K. from the E.U. would have and how such withdrawal would affect us.

The announcement of Brexit caused significant volatility in global stock markets and currency exchange rate fluctuations that resulted in the strengthening of the U.S. dollar against foreign currencies in which we conduct business. The strengthening of the U.S. dollar relative to other currencies may adversely affect our operating results. The announcement of Brexit and the withdrawal of the U.K. from the E.U. may also create global economic uncertainty, which may cause our customers to closely monitor their costs and reduce their spending budgets. Any of these effects of Brexit, among others, could adversely affect our business, financial condition, operating results and cash flows.

The market price of our common stock has been volatile and may continue to be volatile and the value of your investment may decline.

Volatility may cause wide fluctuations in the price of our common stock on the NASDAQ Global Select Market. The market price of our common stock is likely to be affected by:

We have received no written comments regarding our periodic or current reports from the Staff of the SEC that were issued 180 days or more preceding the end of our 2016 fiscal year and that remain unresolved.

Field Locations. We locate our field operations in markets with attractive demographics and strong growth prospects. Within each market, we are located in areas that allow for easy delivery of units to our customers over a wide geographic area. In addition, when cost effective, we seek locations that are visible from high traffic roads in order to advertise our products and our name. A typical branch consists of outdoor storage space for units not currently on rent and a small office. These properties tend to be one to five acre sites with little development needed for us to use them, other than a paved or hard-packed surface, utilities and proper zoning. In North America we own 3 locations, and in the U.K., we own 2 locations. We lease the remaining locations in which we operate.

Other. We own a 43-acre facility in Maricopa, Arizona that is primarily used to rebrand, remanufacture and perform major repairs and maintenance on our existing rental fleet and build custom sale units.

We believe that satisfactory alternative properties can be found in all of our markets if we do not renew these existing leased properties.

We are party from time to time to various claims and lawsuits that arise in the ordinary course of business, including claims related to employment matters, contractual disputes, personal injuries and property damage. In addition, various legal actions, claims and governmental inquiries and proceedings are pending or may be instituted or asserted in the future against us and our subsidiaries.

Litigation is subject to many uncertainties, and the outcome of the individual litigated matters is not predictable with assurance. It is possible that certain of the actions, claims, inquiries or proceedings, including those discussed above, could be decided unfavorably to us or any of our subsidiaries involved. Although we cannot predict with certainty the ultimate resolution of lawsuits, investigations and claims asserted against us, we do not believe that the ultimate resolution of these claims or lawsuits will have a material adverse effect on our business, financial condition, results of operations or cash flows.

Our common stock trades on The NASDAQ Global Select Market under the symbol “MINI”. The following are the high and low sale prices for the common stock during the periods indicated as reported by the NASDAQ Stock Market.

We had 62 holders of record of our common stock on January 27, 2017. The number of beneficial owners is substantially greater than the number of record holders because a large portion of our common stock is held of record in broker “street names.”

In November 2013, our Board of Directors (the “Board”) authorized the initiation of a quarterly cash dividend program to all of our common stockholders with the first quarterly common stock cash dividend paid in the first quarter of 2014. Each dividend payment is subject to review and approval by the Board. We paid cash dividends of approximately $0.82 per share for a total of $36.4 million during fiscal 2016 and approximately $0.75 per share for a total of $33.7 million during fiscal 2015. Our Credit Agreement contains certain restrictions on the declaration and payment of dividends.

On November 6, 2013, the Board approved a share repurchase program authorizing up to $125.0 million of our outstanding shares of common stock to be repurchased. On April 17, 2015, the Board authorized up to an additional $50.0 million of our outstanding shares of common stock to be repurchased, for a total of $175.0 million under the share repurchase program. The shares may be repurchased from time to time in the open market or in privately negotiated transactions. The share repurchases are subject to prevailing market conditions and other considerations. The share repurchase program does not have an expiration date and may be suspended or terminated at any time by the Board. All shares repurchased are held in treasury.

During fiscal 2016, we purchased approximately 0.4 million shares of our common stock at a cost of $10.8 million under the authorized share repurchase program. During fiscal 2016, we also withheld approximately 16,000 shares of vested stock awards from employees, for an approximate value of $0.5 million, to satisfy minimum tax withholding obligations. These shares were not acquired pursuant to the share repurchase program.

The table below summarizes the information about purchases of our common stock during the quarterly period ended December 31, 2016:

We are a capital-intensive business. Therefore, in addition to focusing on measurements calculated in accordance with generally accepted accounting principles in the U.S. (“GAAP”), we focus on EBITDA, adjusted EBITDA and free cash flow to measure our operating results. EBITDA, adjusted EBITDA and the resultant margins, and free cash flow are non-GAAP financial measures. As such, we include in this Annual Report on Form 10-K reconciliations to their most directly comparable GAAP financial measures. We also evaluate our operations on a constant currency basis. The non-GAAP data, reconciliations and a description of the limitations of these measures are included below.

EBITDA and Adjusted EBITDA. EBITDA is defined as net income before discontinued operation, net of tax (if applicable), interest expense, income taxes, depreciation and amortization, and debt restructuring or extinguishment expense (if applicable), including any write-off of deferred financing costs. Adjusted EBITDA further excludes certain non-cash expenses, as well as transactions that management believes are not indicative of our ongoing business. Because EBITDA and adjusted EBITDA, as defined, exclude some but not all items that affect our cash flow from operating activities, they may not be comparable to similarly titled performance measures presented by other companies.

We present EBITDA and adjusted EBITDA because we believe that they provide an overall evaluation of our financial condition and useful information regarding our ability to meet our future debt payment requirements, capital expenditures and working capital requirements. EBITDA and adjusted EBITDA have certain limitations as analytical tools and should not be used as substitutes for net income, cash flows, or other consolidated income or cash flow data prepared in accordance with GAAP. EBITDA and adjusted EBITDA margins are calculated as EBITDA and adjusted EBITDA divided by total revenues expressed as a percentage.

Reconciliation of net income, the most directly comparable GAAP measure, to EBITDA and adjusted EBITDA is as follows:

Free Cash Flow. Free cash flow is defined as net cash provided by operating activities, minus or plus, net cash used in or provided by investing activities, excluding acquisitions and certain transactions. Free cash flow is a non-GAAP financial measure and is not intended to replace net cash provided by operating activities, the most directly comparable financial measure prepared in accordance with GAAP. We present free cash flow because we believe it provides useful information regarding our liquidity and ability to meet our short-term obligations. In particular, free cash flow indicates the amount of cash available after capital expenditures for, among other things, investments in our existing business, debt service obligations, payment of authorized quarterly dividends, repurchase of our common stock and strategic small acquisitions.

Reconciliation of net cash provided by operating activities to free cash flow is as follows:

Constant Currency. We calculate the effect of currency fluctuations on current periods by translating the results for our business in the U.K. during the applicable period using the average exchange rates from the comparative prior-year period. We present constant currency information to provide useful information to assess our underlying business excluding the effect of material foreign currency rate fluctuations.

The following discussion of our financial condition and results of operations should be read together with the consolidated financial statements and the accompanying notes included elsewhere in this Annual Report. This discussion contains forward-looking statements that involve risks and uncertainties. Our actual results may differ materially from those anticipated in those forward-looking statements as a result of certain factors, including, but not limited to, those described under “Item 1A. Risk Factors.” The tables and information in this “Management’s Discussion and Analysis of Financial Conditions and Results of Operations” section were derived from exact numbers and may have immaterial rounding differences.

We believe we are the world’s leading provider of portable storage solutions, maintaining a strong leadership position in virtually all markets served. Our mission is to be the leader in portable storage solutions to customers throughout North America and the U.K. and specialty containment solutions in the U.S. We are committed to providing our customers with superior service and access to a high-quality and diverse fleet. In managing our business, we focus on renting rather than selling our units, with rental revenues representing approximately 94.4% of our total revenues for the year ended December 31, 2016. We believe this strategy provides us with predictable, recurring revenue. Additionally, our assets have long useful lives, low maintenance costs and generally maintain their value throughout their useful lives. We also sell new and used units, and provide delivery, installation and other ancillary products and value-added services.

On May 9, 2016, we issued $250.0 million aggregate principal amount of the 2024 Notes. The net proceeds from the sale of the 2024 Notes were used to redeem all $200.0 million aggregate principal amount of the 2020 Notes, including related fees, interest and costs for both the redemption of the 2020 Notes and issuance of the 2024 Notes, as well as to repay a portion of the indebtedness outstanding under the Credit Agreement. The refinancing of the Senior Notes enabled us to reduce our overall cost of capital and extended the maturity of a sizeable portion of our outstanding debt.

Throughout 2016, our continuing operational strategic goals included growing revenue and expanding our operating margins by leveraging our infrastructure, focusing on higher returning assets and driving continuous improvements in efficiency. To achieve these goals, we concentrated on generating growth in our core rental business through strong organic growth and opportunistic geographic expansions. We also actively manage fleet utilization and seek to control costs.

Our initiatives in 2016 also included focusing on cross-selling opportunities and leveraging Mobile Mini’s and ETS’ respective geographic coverage and customer bases for growth and expansion as well as implementing the new ERP system to further increase efficiency and data management and provide a scalable platform for growth.

As of December 31, 2016, our network includes 125 portable storage locations, 19 specialty containment locations and 14 combined locations. Our portable storage fleet consists of approximately 211,300 units and our specialty containment business has a fleet of approximately 12,100 units.

Business Environment and Outlook. Approximately 65% of our rental revenue during the twelve-month period ended December 31, 2016 was derived from our North American portable storage business, 19% was derived from our specialty containment business in North America and 16% was derived from our U.K. portable storage business. Our business is subject to the general health of the economy and we utilize a variety of general economic indicators to assess market trends and determine the direction of our business.

Based on our assessment, we expect that the majority of our end markets will continue to drive demand for our products in 2017. In particular, construction, which represents approximately 44% of our consolidated rental revenue is forecasted for continued growth for the next several years. While only 2% of our consolidated rental revenue is generated by oil and gas customers, the oil and gas industry is forecasted to stabilize in the near term, with potential for future growth.

In addition to focusing on GAAP measurements, we focus on EBITDA, adjusted EBITDA, and free cash flow to measure our operating results. As such, we include in this Annual Report on Form 10-K reconciliations to their most directly comparable GAAP financial measures. These reconciliations and descriptions of why we believe these measures provide useful information to investors as well as a description of the limitations of these measures are included in “Item 6. Selected Financial Data.”

Of the $508.6 million of total revenues in 2016, $410.6 million, or 80.7%, related to the portable storage business and $98.1 million, or 19.3%, related to the specialty containment business. In the prior-year, $423.5 million, or 79.8%, related to the portable storage business and $107.3 million, or 20.2%, related to the specialty containment business. The wood mobile office business divested in May 2015 contributed approximately $16.9 million of total revenue and $15.8 million of rental revenue during the year ended December 31, 2015.

Rental Revenues. Portable storage rental revenue for the twelve months ended December 31, 2016 increased $7.8 million, or 2.1%, as compared to the prior-year period, excluding the effect of the wood mobile office fleet divestiture discussed above. Adjusting for an unfavorable change in currency translation rates and excluding the divested wood mobile office assets, rental revenue increased approximately 4.7%, as compared to the prior-year period. The increase was driven by a 2.3% increase in year-over-year rental rates and a 1.9% increase in units on rent. Excluding the divested wood mobile office fleet and adjusting for the unfavorable currency effect, yield (calculated as rental revenues divided by average units on rent) increased approximately 2.7% as compared to the prior-year period, largely driven by the rate increase in the current-year period. The 4.7% rental revenue growth was achieved despite challenges related to turnover in our North American sales force, which we are actively addressing through revised hiring processes, incremental sales management and focused training.

Rental revenues within the specialty containment business decreased $6.7 million, or 6.7%, for the twelve-month period ended December 31, 2016, as compared to the prior-year period. This decline was primarily driven by decreases in upstream revenues due to challenges in the oil and gas sector, as well as a decrease in our diversified business caused by weakness in the mining sector and fewer infrastructure projects. Revenues in the downstream market increased slightly in 2016, as compared to 2015. Demand in the underlying downstream business remains strong; however, high-capacity production resulting from lower oil prices has caused the postponement of maintenance projects in that sector.

Sales Revenues. We focus on rental revenues. In general, sales of units from our fleet occur due to a particular customer need, or due to having fleet in excess of demand at a particular location. Portable storage sales revenue for the twelve months ended December 31, 2016 decreased $0.8 million, or 3.6%, to $21.6 million, compared to $22.4 million in the prior-year period. Specialty containment sales revenue for the twelve months ended December 31, 2016 decreased $2.6 million to $4.9 million, compared to $7.6 million in the prior-year period.

Costs and Expenses. The following tables depict costs and expenses by type of business for the twelve-month periods ended December 31:

Rental, Selling and General Expenses. Rental, selling and general expenses for the twelve months ended December 31, 2016 of $309.3 million decreased $17.0 million, or 5.2%, as compared to the prior-year period. This net decrease resulted from an $18.2 million reduction related to the portable storage business, offset by a $1.3 million increase related to the specialty containment business. As a percentage of total revenues, rental, selling and general expenses were 60.8% for the twelve months ended December 31, 2016, which was down from 61.5% in 2015.

Within the portable storage business, rental, selling and general expenses for the twelve months ended December 31, 2016 decreased $18.2 million, or 6.9%, from 2015. Included in the current-year and prior-year periods was $0.8 million and $7.9 million, respectively, of expenses that were not indicative of our operations. In 2016, the expenses were associated with the departure of an executive officer, a sales tax remittance and acquisition-related expenses. The rental, selling and general expenses for the twelve months ended December 31, 2015 included $2.6 million in acquisition-related expenses, $4.4 million of transition service expenses and $0.9 million of expenses related to an unclaimed property settlement.

Excluding the expenses discussed above, rental, selling and general expenses within the portable storage business decreased $11.2 million during the twelve months ended December 31, 2016, as compared to the prior-year period. This decrease in portable storage business rental, selling and general expenses was driven largely by fluctuations in currency translation rates, decreased variable compensation, including stock-based compensation, as well as lower fleet freight and fuel costs resulting from decreased activity due to the divestiture of our wood mobile office fleet, as well as lower fuel prices generally. Salaries and wages and other operating costs within the portable storage business increased due to the expansion of shared services, as well as the implementation and operation of our new ERP system; however, these increases were largely offset by increased allocations of overhead expenses to the specialty containment business as we continue to consolidate our infrastructure and shared services.

Rental, selling and general expenses for the specialty containment business increased $1.3 million in the current-year period, as compared to the prior-year period. The increase was primarily due to increased allocations of overhead expenses to the specialty containment business, partially offset by decreases in salaries and wages and other operating costs. In the

current-year period, the consolidation of our infrastructure and shared services resulted in the elimination of redundant employee positions. In addition, lower fleet freight and fuel costs resulted from decreased rental activity.

Cost of Sales. Cost of sales is the cost related to our sales revenue only. Within the portable storage business, cost of sales was $13.3 million and $14.6 million in the twelve-month periods ended December 31, 2016 and 2015, respectively. Portable storage sales profit was $8.3 million and $7.8 million for the twelve-month periods ended December 31, 2016 and 2015, respectively. Sales profit expressed as a percentage of sales revenue (sales profit margin) was 38.3% in the twelve months ended December 31, 2016 and 34.9% in the prior-year period.

Within the specialty containment business, cost of sales was $3.2 million and $5.1 million in the twelve months ended December 31, 2016 and 2015, respectively. Specialty containment sales profit was $1.8 million and $2.5 million for the twelve-month periods ended December 31, 2016 and 2015, respectively.

Restructuring expenses. The restructuring expenses in 2016 resulted primarily to the continuation of projects initiated in prior years.

For the twelve months ended December 31, 2016 and 2015, $2.0 million and $19.7 million, respectively, related to activities associated with the integration of ETS into the existing Mobile Mini infrastructure, including the re-alignment of sales leadership with operational leadership.

Also included in restructuring expense were costs to shift our business away from the wood mobile office business, including abandonment of yards, totaling approximately $3.3 million and $0.8 million for the years ended December 31, 2016 and 2015, respectively.

Of the total $6.0 million of restructuring expense recognized in the twelve months ended December 31, 2016, approximately $0.4 million was non-cash. Of the total $20.8 million of restructuring expense recognized in the twelve months ended December 31, 2015, approximately $17.0 million was non-cash. We expect to recognize approximately $3.0 million in restructuring expenses related to these restructurings in 2017.

Asset Impairment Charge and Loss on Divestiture, Net. The $66.1 million net asset impairment charge and loss on divestiture for the twelve months ended December 31, 2015 was due to the impairment and sale of our wood mobile office fleet in our North American portable storage segment. See additional discussion regarding the impairment of the wood mobile office assets in Note 4 “Impairment and Divestiture of North American Wood Mobile Offices” to the accompanying condensed consolidated financial statements.

Depreciation and Amortization Expense. Depreciation and amortization expense increased $3.4 million in the twelve-month period ended December 31, 2016, as compared to the prior-year period. This increase was due primarily to increased depreciation expense related to property, plant and equipment, including the implementation of our new ERP system. Partially offsetting this increase was a decrease in depreciation expense related to the wood mobile office units divested in May 2015. In the twelve months ended December 31, 2015, we recognized $1.3 million of depreciation expense related to these units.

Interest Expense. Interest expense decreased $3.2 million, or 8.8%, to $32.7 million in the twelve months ended December 31, 2016, compared to $35.9 million in the prior-year period. Our average debt outstanding in the twelve months ended December 31, 2016 was $929.1 million, as compared to $902.9 million in the prior-year period. The weighted average interest rate on our debt was 3.3% and 3.6% for the twelve-month periods ended December 31, 2016 and 2015, respectively, excluding the amortization of debt issuance costs. Taking into account the amortization of debt issuance costs, the weighted average interest rate was 3.5% and 4.0% for the twelve-month periods ended December 31, 2016 and 2015, respectively.

The decrease in the effective interest rate was due to the issuance of the 2024 Notes and extinguishment of the 2020 Notes in the second quarter of 2016, along with the refinancing of our line of credit in the fourth quarter of 2015. Each of these activities resulted in lowered interest rates. See additional discussion in Note 6 “Debt” to the accompanying condensed consolidated financial statements.

Debt Extinguishment Expense and Deferred Financing Costs Write-off. As a result of the redemption of the 2020 Notes during the current-year period, we recognized $9.2 million in debt extinguishment expense, consisting of $7.9 million in debt redemption premiums and $1.3 million in contractually required interest above the amount payable prior to the redemption. Additionally, we wrote off $2.3 million of previously deferred costs associated with the 2020 Notes that had not yet been amortized.

Provision (Benefit) for Income Taxes. For the twelve months ended December 31, 2016, we had a $21.7 million provision for income taxes, compared to a net benefit of $4.8 million in the prior-year period. Our effective income tax rate was 31.4% for the twelve months ended December 31, 2016. Our current year income tax was affected by an enacted tax rate change in the U.K. reducing the tax rate from 18% to 17% and current year deductions for stock compensation. Our prior-year income tax was affected similarly by an enacted rate change in the U.K. income tax rate reducing the tax rate from 20% to 18%, as well as losses in North America driven by the asset impairment and restructuring expenses as discussed previously in this Annual Report on Form 10-K. The change in the U.K. income tax rate resulted in a $0.9 million benefit and $1.4 million benefit for the years ended December 31, 2016 and December 31, 2015, respectively.

Excluding the North America asset impairment and the $1.4 million cumulative effect on prior-year deferred liabilities of the U.K. rate change, our tax rate for the year ended December 31, 2015 was 33.4%. The decrease from 33.4% to 31.4% resulted primarily from the enacted tax rate change in the U.K. as discussed above and certain stock compensation deductions.

At December 31, 2016, we had a federal net operating loss carryforward of approximately $236.6 million, which expires, if unused, from 2028 to 2034. In addition, we had net operating loss carryforwards in the various states in which we operate. Over the past three years, we have generated $149.2 million of federal taxable income. At December 31, 2016, we had $117.1 million of gross deferred tax assets included within the net deferred tax liability on our balance sheet, and a $1.1 million valuation allowance. We believe, based on internal projections, that we will generate sufficient taxable income needed to realize the corresponding unreserved federal and state deferred tax assets to the extent they are recorded as deferred tax assets in our balance sheet. However, given that the federal net operating loss carryforwards that give rise to the deferred tax asset expire over seven years beginning in 2028, there could be changes in management’s judgment in future periods with respect to the recoverability of these assets. See Note 7 “Income Taxes” to the accompanying consolidated financial statements for further discussion on income taxes.

Net Income. As a result of the income statement activity discussed above, we had net income of $47.2 million for the twelve months ended December 31, 2016, as compared to $5.6 million for the twelve months ended December 31, 2015.

Adjusted EBITDA. For the twelve-month period ended December 31, 2016, we realized adjusted EBITDA of $190.4 million, a decrease of $10.5 million, or 5.2%, as compared to adjusted EBITDA of $200.8 million in the prior-year period. Growth in our current portable storage business was offset by short-term pressure resulting from the divestiture of our wood mobile office fleet, unfavorable currency fluctuations of $4.0 million, increased repairs and maintenance expense, and increased operating costs related to our recently implemented ERP system, as well as the year-over-year decline in specialty containment rental revenue. Our adjusted EBITDA margins were 37.4% and 38.1% for the twelve-month periods ended December 31, 2016 and 2015, respectively.

During the twelve months ended December 31, 2016, adjusted EBITDA related to the portable storage business decreased $1.7 million, or 1.1%, to $159.0 million, from $160.7 million in the prior-year period. Adjusted EBITDA related to the specialty containment business decreased $8.8 million, or 21.8%, to $31.4 million during the twelve months ended December 31, 2016, from $40.2 million during the prior-year period. Adjusted EBITDA margins for the twelve months ended December 31, 2016 were 38.7% for the portable storage business and 32.0% for the specialty containment business.

The following table sets forth certain financial information as calculated on a constant currency basis:

(1)See “Non-GAAP Data and Reconciliations” earlier in this Annual Report on Form 10‑K.

Total Revenues. The following tables depicts revenue by type of business for the twelve-month periods ended December 31:

Total revenues in 2015 increased $85.3 million, or 19.1%, to $530.8 million, from $445.5 million in 2014. The increase is due to a $100.8 million increase related to our recently acquired specialty containment business, partially offset by a $15.5 million decrease in the portable storage business related to the divested wood mobile office business, which contributed $46.1 million of total revenue in 2014, compared to $17.0 million in 2015, a decrease of $29.1 million. Rental, our primary revenue focus, accounted for approximately 93.2% of total revenues during 2015, and increased $84.4 million, or 20.6%. Increased rental revenue in the specialty containment business was partially offset by a decrease in the portable storage business due to the divested wood mobile office business.

Rental Revenues. Within the portable storage business the $9.8 million decrease in rental revenues is a result of the second quarter 2015 divestiture of our wood mobile office business, as discussed previously in this Annual Report on Form 10-K. The divested business contributed rental revenue of $15.8 million in 2015, compared to $43.4 million in 2014, a decrease of $27.6 million. Rental revenue related to the remaining portable storage business increased approximately $17.8 million, or 4.9%, driven by a 4.5% increase in rental rates as well as a 2.0% increase in units on rent. These increases in rental revenue were partially offset by unfavorable currency translation rates in 2015, as compared to 2014. Adjusting for the change in currency translation rates and the divested wood mobile office business, rental revenue increased approximately 6.7%. Excluding the divested wood mobile office business and adjusting for the unfavorable currency effect, yield (calculated as rental revenues divided by average units on rent) increased approximately 4.6%, as compared to 2014.

Sales Revenues. Portable storage sales revenue for the year ended December 31, 2015 decreased $9.0 million, or 28.8%, to $22.4 million, compared to $31.4 million in the prior year. Revenue from specialty containment sales was $7.6 million for the year ended December 31, 2015. We focus on rental revenues; as such, in general, sales of units from our fleet occur due to a particular customer need, or due to having fleet in excess of demand at a particular location.

Costs and Expenses. The following tables depicts costs and expenses by type of business for the twelve-month periods ended December 31:

Rental Selling and General Expenses. Rental, selling and general expenses for portable storage decreased $13.8 million, or 5.0%, and as a percentage of total portable storage revenues decreased to 62.3% from 63.2% for the years ended December 31, 2015 and 2014, respectively. Included in rental, selling and general expenses for 2015 are certain expenses totaling $7.9 million that management does not consider indicative of our business. These expenses include $2.6 million in acquisition-related expenses, including consulting costs to integrate business functions in conjunction with the ETS Acquisition, $4.4 million incurred to provide transition services in conjunction with the divestiture of our wood mobile office business and $0.9 million related to an unclaimed property settlement. In 2014 we incurred $5.1 million of expenses related to acquisitions, primarily the ETS Acquisition.

The increase in expenses due to the above items was more than offset by approximately $16.6 million of other net decreases in the portable storage business rental, selling and general expenses. The $16.6 million decrease was driven by lower fleet freight and fuel costs, and repairs and maintenance due largely to the decreased activity related to our wood mobile office divestiture, decreasing fuel prices and lower fleet positioning activity. Excluding expenses associated with providing transition services, repairs and maintenance on our portable storage rental fleet as a percentage of rental revenue was 5.0%, compared to 6.7% in 2014. These decreases in costs were partially offset by smaller increases related to salaries and professional fees and service contracts, including technology-related upgrades and non-capitalizable expenses associated with our ERP system implementation. Specialty containment rental, selling and general expenses was $62.5 million for the year ended December 31, 2015, or 58.3% of total specialty containment revenues.

The approximately $4.4 million incurred to provide transition services related to the divestiture of our wood mobile office business includes direct expenses to transport and maintain the assets on behalf of the purchaser, as well as expenses related to wood mobile offices on our leased properties, and the provision of certain administrative services such as billing and cash collection.

Cost of Sales. The cost of sales is the cost related to our sales revenue only. Within the portable storage business, cost of sales was $14.6 million and $21.8 million in the years ended December 31, 2015 and 2014, respectively. Portable storage sales revenue, less cost of sales (sales profit), was $7.8 million and $9.6 million for the twelve-month periods ended December 31, 2015 and 2014, respectively. Sales profit expressed as a percentage of sales revenue (sales profit margin) was 34.9% in the year ended December 31, 2015 and 30.5% in the prior-year. Cost of sales related to our specialty containment

products was $5.1 million in the year ended December 31, 2015. Specialty containment products sales profit and profit margin were $2.5 million and 32.7% in the year ended December 31, 2015.

Restructuring Expenses. Of the $20.8 million in restructuring expenses recognized in 2015, $19.7 million related to activities associated with the integration of ETS into the existing Mobile Mini infrastructure, including the re-alignment of sales leadership with operational leadership.

During the fourth quarter of 2015, as the Company was finalizing locations in Southern California for combined portable storage and specialty containment equipment operations, we determined that certain of our current locations in Southern California would either not be optimal or available to accommodate efficient operations and provide desired proximity to our combined customer base. To accommodate the needs of the planned combined operations, the Company leased new property, exited certain properties and abandoned approximately 5,000 units of the portable storage fleet in Southern California at the legacy yards. This abandonment resulted in $13.7 million of restructuring expense in the fourth quarter, representing the write-down of this fleet to zero value.

Other costs in 2015 related to execution of the ETS integration and geographic expansion included $4.6 million for severance and benefits (including $1.6 million of share-based compensation) and $1.4 million for the write-off and loss on sale of property, plant and equipment.

The remaining 2015 restructuring costs of $1.1 million relate primarily to costs involved to shift our business away from the wood mobile office business, including abandonment of yards. Of the total $20.8 million of restructuring expense recognized in the twelve months ended December 31, 2015, approximately $17.0 million was non-cash.

The 2014 restructuring costs primarily relate to the transition of key leadership positions, as well as the closure of our Belfast, North Ireland location.

Asset Impairment Charge and Loss on Divestiture, Net. As discussed previously in this Annual Report on Form 10-K, during the twelve months ended December 31, 2015, we recorded impairment charges and loss on divestiture of $66.1 million related to our wood mobile offices in our North American portable storage segment. See additional discussion regarding the impairment and divestiture of the wood mobile office assets in Note 4 to the accompanying consolidated financial statements. Asset impairment charges, net of recoveries, were $0.6 million for the twelve months ended December 31, 2014 and relate to net gains and losses upon completion of sale, or other disposal of assets impaired in a 2013 assessment of the rental fleet.

Depreciation and Amortization. Depreciation and amortization expense increased $21.0 million for the twelve months ended December 31, 2015, as compared to the prior-year period. Increased depreciation of $23.6 million related to the specialty containment business was partially offset by a decrease of $2.6 million related to the portable storage business. Subsequent to the impairment of the wood mobile office units, no additional depreciation was recognized on these assets.

Interest Expense. Interest expense increased $7.2 million, or 25.0%, to $35.9 million in 2015. In December 2014, we borrowed funds under our prior credit agreement to facilitate the ETS Acquisition. Our average debt outstanding in the twelve-month period ended December 31, 2015 was $902.9 million, as compared to $539.0 million in the prior-year period. The weighted average interest rate on our debt was 3.6% and 4.8% for the twelve months ended December 31, 2015 and 2014, respectively, excluding the amortization of debt issuance costs. Taking into account the amortization of debt issuance costs, the weighted average interest rate was 4.0% and 5.3% for the twelve-month periods ended December 31, 2015 and 2014, respectively. The decrease in the average interest rate is primarily due to the increase of our lower rate line of credit, as a percentage of our overall debt.

Deferred Financing Costs Write-off. As discussed in Note 6 to the accompanying consolidated financial statements, we entered into the Credit Agreement in December 2015, resulting in the write-off of $0.9 million of deferred financing costs related to the prior credit agreement.

(Benefit) Provision for Income Taxes. During the twelve-month period ended December 31, 2015, we had a $4.8 million benefit for income taxes on pre-tax income of $0.8 million. In the prior-year we had a $26.0 million provision for tax on pre-tax income of $70.4 million. Our effective income tax rate in the current year was affected by an enacted change in the U.K. income tax rate, as well as losses in North America driven by the asset impairment and restructuring expenses as discussed previously in this Annual Report on Form 10-K. The change in the U.K. income tax rate resulted in a $1.4 million benefit when applied to our December 31, 2014 deferred tax liability, and a $0.5 million benefit to current year taxes.

Excluding the $1.9 million total tax benefit related to the rate change, our tax benefit would have been approximately $2.9 million, which is in excess of our pre-tax income, due primarily to the magnitude of the loss in North America, which has a higher income tax rate. Excluding the North America asset impairment and the $1.4 million cumulative effect on prior-year deferred liabilities of the U.K. rate change, our tax rate for the year ended December 31, 2015 was 33.4%. See Note 7 to the accompanying consolidated financial statements for further discussion on income taxes.

Net Income. Primarily due to the $66.1 million impairment and divestiture loss, the $20.8 million restructuring expenses and the other income statement activity discussed above, including the ETS Acquisition, our net income decreased to $5.6 million for the year ended December 31, 2015, compared to net income of $44.4 million in the prior-year.

Adjusted EBITDA. Adjusted EBITDA increased $38.7 million, or 23.9%, to $200.8 million in 2015, compared to $162.1 million in 2014. Of this increase, $1.5 million related to our portable storage business and $37.2 million related to our specialty containment business. Adjusted EBITDA margins were 38.1% and 36.4% for 2015 and 2014, respectively. Adjusted EBITDA margins for the twelve-month period ended December 31, 2015 were 38.3% for our portable storage business and 37.4% for our specialty containment business.

Renting is a capital-intensive business that requires us to acquire assets before they generate revenues, cash flow and earnings. The majority of the assets that we rent have very long useful lives and require relatively little maintenance expenditures. Most of the capital we have deployed in our rental business historically has been used to expand our operations geographically, to execute opportunistic acquisitions, to increase the number of units available for rent at our existing locations, and to add to the mix of products we offer. During recent years, our operations have generated annual cash flow that exceeds our pre-tax earnings, particularly due to cash flow from operations and the deferral of income taxes caused by accelerated depreciation of our fixed assets in our tax return filings. Our strong cash from operating activities for the years ended December 31, 2016, 2015 and 2014 of $136.2 million, $152.8 million and $120.6 million, respectively, resulted in free cash flow of $64.7 million, $73.6 million and $104.8 million, respectively. In addition to free cash flow, our principal current source of liquidity is the Credit Agreement described below.

Revolving Credit Facility. On December 14, 2015, we entered into the Credit Agreement with Deutsche Bank AG New York Branch, as administrative agent, and other lenders party thereto. The Credit Agreement provides for a five-year, $1.0 billion first lien senior secured revolving credit facility maturing on or before the earlier of (i) December 14, 2020 and (ii) the date that is 90 days prior to the final maturity date of the Senior Notes if such Senior Notes remain outstanding on such date. The Credit Agreement also provides for the issuance of irrevocable standby letters of credit by U.S. lenders in amounts totaling up to $50.0 million, by U.K.-based lenders in amounts totaling up to $20.0 million, and by Canadian-based lenders in amounts totaling up to $20.0 million.

The obligations of us and our subsidiary guarantors under the Credit Agreement are secured by a blanket lien on substantially all of our assets. At December 31, 2016, we had $641.2 million of borrowings outstanding and $354.3 million of additional borrowing availability under the Credit Agreement. We were in compliance with the terms of the Credit Agreement as of December 31, 2016 and were above the minimum borrowing availability threshold and therefore not subject to any financial maintenance covenants.

Amounts borrowed under the Credit Agreement and repaid or prepaid during the term may be reborrowed. Outstanding amounts under the Credit Agreement bear interest at our option at either: (i) the London interbank offered rate (“LIBOR”) plus an applicable margin (“LIBOR Loans”), or (ii) the prime rate plus an applicable margin (“Base Rate Loans”). The applicable margin for each type of loan is based on an availability-based pricing grid and ranges from 1.25% to 1.75% for

LIBOR Loans and 0.25% to 0.75% for Base Rate Loans at each measurement date The margins in effect as of December 31, 2016 are 1.50% for LIBOR Loans and 0.50% for Base Rate Loans.

Availability of borrowings under the Credit Agreement is subject to a borrowing base calculation based upon a valuation of our eligible accounts receivable, eligible rental fleet (including units held for sale, work-in-process and raw materials) and machinery and equipment, each multiplied by an applicable advance rate or limit. The rental fleet is appraised at least once annually by a third-party appraisal firm and up to 90% of the net orderly liquidation value, as defined in the Credit Agreement, is included in the borrowing base to determine how much we may borrow under the Credit Agreement.

The Credit Agreement provides for U.K. borrowings, which are, at our option, denominated in either Pounds Sterling or Euros, by our U.K. subsidiary based upon a U.K. borrowing base; Canadian borrowings, which are denominated in Canadian dollars, by our Canadian subsidiary based upon a Canadian borrowing base; and U.S. borrowings, which are denominated in U.S. dollars, based upon a U.S. borrowing base along with any Canadian assets not included in the Canadian subsidiary.

The Credit Agreement also contains customary negative covenants, including covenants that restrict our ability to, among other things: (i) allow certain liens to attach to Mobile Mini or subsidiary assets, (ii) repurchase or pay dividends or make certain other restricted payments on capital stock and certain other securities, or prepay certain indebtedness, (iii) incur additional indebtedness or engage in certain other types of financing transactions, and (iv) make acquisitions or other investments. In addition, we must comply with a minimum fixed charge coverage ratio of 1.00 to 1.00 as of the last day of each quarter, upon the minimum availability amount under the Credit Agreement falling below the greater of (y) $90 million and (z) 10% of the lesser of the then total revolving loan commitment and aggregate borrowing base.

We believe our cash provided by operating activities will provide for our normal capital needs for the next twelve months. If not, we have sufficient borrowings available under our Credit Agreement to meet any additional funding requirements. We monitor the financial strength of our lenders on an ongoing basis using publicly-available information. Based upon that information, we do not presently believe that there is a likelihood that any of our lenders will be unable to honor their respective commitments under the Credit Agreement.

Senior Notes. On May 9, 2016, we issued $250.0 million aggregate principal amount of the 2024 Notes at an initial offering price of 100% of their face value. The net proceeds from the sale of the 2024 Notes were used to (i) redeem all $200.0 million aggregate principal amount of our outstanding 2020 Notes at a redemption price of 103.938% of the principal amount thereof plus accrued and unpaid interest to, but not including, the redemption date of June 8, 2016, (ii) repay a portion of the indebtedness outstanding under the Credit Agreement, and (iii) pay fees and expenses related to the offering of the 2024 Notes.

The 2024 Notes bear interest at a rate of 5.875% per year, accruing from May 9, 2016, have an eight-year term and mature on July 1, 2024. Interest on the 2024 Notes is payable semiannually in arrears on January 1 and July 1, beginning on January 1, 2017. The 2024 Notes are senior unsecured obligations of the Company and are unconditionally guaranteed on a senior unsecured basis by certain of our existing and future domestic subsidiaries.

Operating Activities. Net cash provided by operating activities was $136.2 million for the twelve months ended December 31, 2016, compared to $152.8 million in the prior year, a decrease of $16.6 million. The twelve months ended December 31, 2016 reflects an increase in net income to $47.2 million, from net income of $5.6 million in the prior-year period. This $41.7 million increase in net income is due primarily to non-cash items. Non-cash expenses in the current-year period include $21.6 million in deferred tax expense, $63.7 million of depreciation and amortization and $7.4 million of share-based compensation expense. Non-cash expenses in the prior-year period include a $66.1 million asset impairment charge and loss on divestiture, $12.4 million of non-cash restructuring charges, $60.3 million in depreciation and amortization and $13.8 million of share-based compensation expense, offset by a $5.6 million decrease in deferred taxes. In addition, in 2016 we recognized $9.2 million of debt extinguishment costs that reduced net income, but are a financing activity in the consolidated statement of cash flows.

Excluding the net total non-cash income statement items and debt extinguishment expense of $108.1 million in the current-year period and $150.6 million in the prior-year period, cash generated by net income decreased slightly to $155.3 million, from $156.1 million in the prior-year period. The change in working capital accounts resulted in cash outflows of $19.1 million in the 2016 period and $3.3 million in the 2015 period. An increase in receivables in the twelve months ended December 31, 2016 due to the implementation of our new ERP system, as well as changes in the invoicing process instituted by our largest portable storage customer, resulted in a cash outflow. This outflow was partially offset by an increase in

accrued liabilities primarily due to the timing of interest payments related to the 2024 Notes. Interest payments on the 2024 Notes are payable in January and June, as compared to the 2020 Notes for which interest payments which were payable in June and December.

Net cash provided by operating activities was $152.8 million for the twelve months ended December 31, 2015, compared to $120.6 million in the prior-year period, an increase of $32.2 million. Although the twelve months ended December 31, 2015 reflects a decrease in net income of $38.8 million to $5.6 million, compared to net income of $44.4 million in the prior-year period, the difference is due primarily to non-cash items. Non-cash items in 2015 include a $66.1 million asset impairment charge and loss on divestiture, $12.4 million of non-cash restructuring charges, $60.3 million in depreciation and amortization and $13.8 million of share-based compensation expense, offset by a $5.6 million decrease in deferred taxes. Non-cash items in 2014 include $25.4 million in deferred tax expense, $39.3 million of depreciation and amortization and $15.1 million of share-based compensation expense.

Excluding the net non-cash income statement items of $150.6 million in 2015 and $80.7 million in 2014, cash generated by net income increased $31.0 million to $156.1 million in 2015, from $125.1 million in 2014. The increase is due primarily to the acquired specialty containment business, as well as increased margins in the portable storage business, offset by the decreased portable storage revenue related to the divested wood mobile offices. The change in working capital accounts resulted in cash outflow of $3.3 million in the 2015 period and $4.4 million in the 2014 period, due to normal operating fluctuations.

Cash provided by operating activities is enhanced by the deferral of most income taxes due to the rapid tax depreciation rate of our assets and our federal and state net operating loss carryforwards. At December 31, 2016, we had a federal net operating loss carryforward of approximately $236.6 million and a net deferred tax liability of $356.7 million.

Investing Activities. Net cash used in investing activities was $88.1 million in 2016, compared to $14.4 million in 2015 and $446.8 million in 2014. In 2016, 2015 and 2014, we paid $16.6 million, $18.5 million and $430.9, respectively, for acquisitions. Of the $430.9 million cash paid for acquisitions in 2014, $407.6 related to the ETS Acquisition. Included in investing activities for 2015 is $83.3 million of proceeds related to the divestiture of our wood mobile office business.

Rental fleet net capital expenditures were $43.7 million in 2016, compared to net capital expenditures of $57.9 million in 2015 and $4.2 million in 2014. Rental fleet additions totaled $57.4 million in 2016, of which $32.3 million related to our North America portable storage business, $10.9 million related to our U.K. portable storage business and $14.3 million related to our specialty containment business. Of the $74.7 million of rental fleet additions in 2015, $28.5 million related to our North America portable storage business, $24.0 million related primarily to downstream specialty containment products and $22.2 million related to the U.K. portable storage business. Expenditures for rental fleet in 2016 and 2015 were made to meet demand in geographic areas of high utilization for which it did not make economic sense to reposition our fleet, as well as to meet customer demand for specific types of units. In 2014, we had minimal net capital expenditures, as we alternatively invested in our existing portable storage fleet through repairs and maintenance, which is expensed as incurred, and did not acquire the specialty containment business until late in 2014.

Proceeds from sale of rental fleet units decreased 18.9% in 2016, compared to 2015, and decreased 26.8% in 2015, compared to 2014. In general, sales of units from our fleet occur due to a particular customer need, or due to having fleet in excess of demand at a particular location; as such, the proceeds from sale of rental units will normally fluctuate from year to year.

Property, plant and equipment net capital expenditures were $27.9 million in 2016, $21.3 million in 2015 and $11.6 million in 2014. Included in 2016 and 2015 are $14.9 million and $17.9, respectively, of computer hardware and software expenditures largely related to our new ERP system. The remaining 2016 and 2015 expenditures for property, plant and equipment and 2014 expenditures were primarily for replacement of our transportation equipment.

Included in the $9.9 million of proceeds from sale of property plant and equipment for 2015 is $6.8 million of proceeds received in conjunction with the sale of a legacy location in Southern California, which was disposed of in conjunction with restructuring activity.

The amount of cash that we use during any period in investing activities is almost entirely within management’s discretion. We have no contracts or other arrangements pursuant to which we are required to purchase a fixed or minimum amount of goods or services in connection with any portion of our business. Maintenance capital expenditures includes expenses such as the cost to replace old forklifts, trucks and trailers that we use to move and deliver our products to our

customers, and for replacements to enhance our computer information and communication systems. Our maintenance capital expenditures, excluding expenditures related to our new ERP system, were approximately $8.6 million in 2016, $6.9 million in 2015 and $3.3 million in 2014. In addition, we acquired property, plant and equipment through capital leases totaling $19.0 million, $17.6 million and $16.5 million in 2016, 2015 and 2014, respectively. These leases were primarily for transportation related equipment. We anticipate our near term investing activities will decrease as compared to 2016 and will be primarily focused on supporting growth in the U.K. and downstream specialty containment, additional portable storage rental fleet through remanufacturing, and the addition of transportation equipment. In addition, we may invest in opportunistic acquisitions.

Financing Activities. Net cash used in financing activities was $44.9 million in 2016 and $140.6 million in 2015, compared to net cash provided by financing activities of $329.8 million in 2014. Activity in 2016 includes the issuance of $250.0 million aggregate principal amount of the 2024 Notes at an initial offering price of 100% of their face value. The net proceeds from the sale of the 2024 Notes were used to (i) redeem all $200.0 million aggregate principal amount of our outstanding 2020 Notes at a redemption price of 103.938% of the principal amount thereof plus accrued and unpaid interest to, but not including, the redemption date of June 8, 2016, (ii) repay a portion of the indebtedness outstanding under the Credit Agreement, and (iii) pay fees and expenses related to the offering of the 2024 Notes.

Activity in 2014 includes the financing of the ETS Acquisition utilizing our prior credit agreement, resulting in net borrowings for the year of $386.2 million, as compared to net repayments of lines of credit of $26.5 million in 2016 and $37.8 million in 2015.

We have used free cash flow, along with proceeds from our wood mobile office divestiture, to purchase treasury stock, pay down borrowings and pay dividends. In 2016, 2015 and 2014, we paid cash dividends of $36.4 million, $33.7 million and $31.4 million, respectively, to our stockholders and purchased shares of our common stock of $11.3 million, $61.8 million and $26.0 million (primarily under our share repurchase program), respectively. As of December 31, 2016, we had $641.2 million of borrowings outstanding under our Credit Agreement and approximately $354.3 million of additional borrowings were available to us. Deferred financing cost expenditures in 2016 largely relate to the issuance of the 2024 Notes. Deferred financing costs in 2015 primarily relate to the Credit Agreement.

Our contractual obligations primarily consist of our outstanding balance under the Credit Agreement, $250.0 million aggregate principal amount of the 2024 Notes and obligations under capital leases. We also have operating lease commitments for: (i) real estate properties for the majority of our locations with remaining lease terms typically ranging from one to ten years (ii) delivery, transportation and yard equipment, typically under a five-year lease with purchase options at the end of the lease term at a stated or fair market value price, and (iii) office related equipment. At December 31, 2016, primarily in connection with securing our insurance policies, we provided certain insurance carriers and others with approximately $4.5 million in letters of credit. We currently do not have any obligations under purchase agreements or commitments.

The table below provides a summary of our contractual commitments as of December 31, 2016. Lease renewal options that we currently anticipate exercising at the end of the initial lease period have been included in the schedule below.

We do not maintain any off-balance sheet transactions, arrangements, obligations or other relationships with unconsolidated entities or others that are reasonably likely to have a material current or future effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources.

Our significant accounting policies are disclosed in Note 2 to the accompanying consolidated financial statements. The following discussion addresses our most critical accounting policies, some of which require significant judgment.

Our consolidated financial statements have been prepared in accordance with GAAP. The preparation of these consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses during the reporting period. These estimates and assumptions are based upon expert information, our evaluation of historical results and anticipated future events, and these estimates may change as additional information becomes available. We have identified below our accounting policies that we believe could potentially produce materially different results if we were to change underlying estimates or assumptions.

Revenue Recognition. Rental revenue is generated from the direct rental of our fleet to our customers, including ancillary revenue such as fleet delivery and pickup. We enter into contracts with our customers to rent equipment based on a monthly rate for our portable storage fleet and a daily, weekly or monthly rate for our specialty containment fleet. Revenues from renting are recognized ratably over the rental period. The rental continues until cancelled by the customer or the

Company. Customers may utilize our equipment delivery and pick-up services in conjunction with the rental of equipment, but it is not required. Revenue pursuant to the pick up or delivery of a rented unit is recognized in rental revenue upon completion of the service. When customers are billed in advance, we defer recognition of revenue and record unearned rental revenue at the end of the period. If equipment is returned prior to the end of the contractually obligated period, the excess, if any, between the amount the customer is contractually required to pay, over the cumulative amount of revenue recognized to date, is recognized as incremental revenue upon return.

Sales revenue is primarily generated by the sale of new and used units, and to a lesser extent, parts and supplies sold to specialty containment customers. We recognize revenues from sales of units upon delivery when the risk of loss passes, the price is fixed and determinable and collectability is reasonably assured. We sell our units pursuant to sales contracts stating the fixed sales price.

Share-Based Compensation. We calculate the fair value of stock options using the Black-Scholes-Merton option pricing valuation model, which incorporates various assumptions including volatility, expected life and risk-free interest rates. The fair value of restricted stock awards is estimated as the closing price of our common stock on the date of grant. Compensation related to service-based awards is recognized on a straight-line basis over the vesting period, which is generally three to five years. Compensation expense related to performance-based awards is recognized over the implicit service period of the award based on management’s estimate of the probability of the performance criteria being satisfied, adjusted at each balance sheet date. Expense related to performance-based awards that have multiple vesting dates, is recognized using the accelerated attribution approach, whereby each vesting tranche is treated as a separate award for purposes of determining the implicit service period. Share-based compensation expense is reduced for forfeitures which are estimated at the time of grant based on historical experience and revised in subsequent periods if actual forfeitures differ from estimates.

Purchase Accounting. We account for acquisitions under the acquisition method. Under the acquisition method of accounting, we record assets acquired and liabilities assumed at their estimated fair market value on the date of acquisition. Goodwill is measured as the excess of the fair value of the consideration transferred over the fair value of the identifiable net assets. Estimated fair values of acquired assets and liabilities is provisional and could change as additional information is received. We finalize valuations as soon as practicable, but not later than one-year from the acquisition date. Any subsequent changes to purchase price allocations results in a corresponding adjustment to goodwill.

The determination of the fair value of intangible assets requires the use of significant judgment with regard to (i) the fair value; and (ii) whether such intangibles are amortizable or non-amortizable and, if amortizable, the period and the method by which the intangible asset will be amortized. We estimate the fair value of acquisition-related intangible assets principally based on projections of cash flows that will arise from identifiable intangible assets of acquired businesses. The projected cash flows are discounted to determine the present value of the assets at the dates of acquisition.

Goodwill. For acquired businesses, we record assets acquired and liabilities assumed at their estimated fair values on the respective acquisition dates. Based on these values, the excess purchase prices over the fair value of the net assets acquired is recorded as goodwill. Of the $703.6 million total goodwill at December 31, 2016, $468.5 million related to the North America portable storage segment, $53.9 million related to the U.K. portable storage segment and $181.2 million related to the specialty containment segment.

Goodwill impairment testing requires judgment, including: the identification of the reporting units; determination of the fair value of each reporting unit; the assignment of assets, liabilities and goodwill to each reporting unit; estimates and assumptions regarding future cash flows and discount rates; and an assumption regarding the form of the transaction in which the reporting unit would be acquired by a market participant. Management assesses potential impairment of goodwill on an annual basis at December 31, or whenever events or changes in circumstances indicate that the carrying value may not be recoverable.

Some factors management considers important which could indicate an impairment review include the following:

Management may choose to assess qualitative factors to determine if it is more-likely-than-not that goodwill might be impaired and whether or not to perform the two-step goodwill impairment test. When the two-step impairment test is performed, the first step requires a comparison of the fair value of each of our reporting unit’s net assets to the respective carrying value of net assets. If the carrying value of a reporting unit’s net assets is less than its fair value, no indication of impairment exists and a second step is not performed. If the carrying amount of a reporting unit’s net assets is higher than its fair value, there is an indication that an impairment may exist and a second step must be performed. If the second step is necessary, management is required to determine the implied fair value of the goodwill and compare it to the carrying value of the goodwill. The fair value of the reporting units would be assigned to the respective assets and liabilities of each reporting unit as if the reporting units had been acquired in separate and individual business combinations and the fair value of the reporting units was the price paid to acquire the reporting units. The excess of the fair value of the reporting units over the amounts assigned to their respective assets and liabilities is the implied fair value of goodwill. If the carrying amount of the reporting unit’s goodwill is greater than the implied fair value of its goodwill, an impairment loss must be recognized for the difference.

In assessing the fair value of the reporting units, management considers both the market approach and the income approach. Under the market approach, the fair value of the reporting unit is based on quoted market prices of companies comparable to the reporting unit being valued. Under the income approach, the fair value of the reporting unit is based on the present value of estimated cash flows. The income approach is dependent on a number of significant management assumptions, including estimated future revenue growth rates and discount rates. Other estimates relate to tax payments, operating margins and capital expenditures. Each approach is given equal weight in arriving at the fair value of the reporting unit.

As of December 31, 2016, we assessed qualitative factors and determined it is more likely than not each of the reporting unit’s assigned goodwill had estimated fair values greater than the respective reporting unit’s individual net asset carrying values; therefore, the two step impairment test was not performed.

In connection with our goodwill impairment test that was conducted as of December 31, 2015, we chose to perform the first step of the goodwill impairment test for each of our reporting units. Our goodwill impairment testing as of this date indicated that both of our portable storage reporting units and our specialty containment reporting unit had estimated fair values which substantially exceeded their respective carrying amounts. The second step of the impairment test was not required for any of the reporting units.

Impairment of Long-Lived Assets (Other than Goodwill). Our rental fleet, property, plant and equipment, and finite-lived intangibles are reviewed for impairment whenever events or changes in circumstances indicate the carrying amount of such assets may be impaired. (See potential impairment indicators under “Goodwill” above.) If this review indicates the carrying value of these assets will not be recoverable, as measured based on estimated undiscounted cash flows over their remaining life, the carrying amount would be adjusted to fair value. The cash flow estimates contain management’s best estimates using appropriate and customary assumptions and projections at the time of evaluation.

During the first quarter of 2015, we entered into discussions regarding the possible sale of our wood mobile offices within our North American portable storage segment. The discussions indicated that the wood mobile offices might be sold at an amount below carrying value and we conducted a review for impairment for these long-lived assets as of March 31, 2015. Based on this review, an impairment loss was recorded in the quarter ended March 31, 2015. The total impairment of the wood mobile offices was $64.6 million during 2015. See additional discussion regarding the impairment and the divestiture of the wood mobile offices in Note 4 to the accompanying consolidated financial statements.

There were no indicators of further impairment at December 31, 2016 or December 31, 2015.

Rental Fleet. Rental fleet is capitalized at cost and depreciated over the estimated useful life of the unit using the straight-line method. Rental fleet is depreciated whether or not it is out on rent. Capitalized cost of our rental fleet includes the price paid to acquire the unit and freight charges to the location when the unit is first placed in service, and when applicable, the cost of our manufacturing or remanufacturing, which includes the cost of customizing units. Ordinary repair and maintenance costs are charged to operations as incurred.

We periodically review depreciable lives and residual values against various factors, including the results of our lenders’ independent appraisal of our rental fleet, practices of our competitors in comparable industries and profit margins achieved on sales of depreciated units.

The table below depicts the estimated useful lives and residual values (presented as a percentage of capitalized cost) for our major categories of portable storage rental fleet.

The table below depicts the estimated useful lives for our major categories of specialty containment rental fleet when purchased new. We estimate zero residual value for our specialty containment fleet as there is a limited secondary market for specialty containment products.

The estimated useful lives and residual values of our rental fleet might change in the future based on changing circumstances. If these estimates change in the future, we may be required to recognize increased or decreased depreciation expense for these assets. For instance, if all our rental fleet units had been placed in service with useful lives 25% less or greater than our current estimated useful lives, we estimate that our annual depreciation expense for the year ended December 31, 2016 would have been $10.7 million higher or $6.4 million lower, respectively.

Similarly, if our rental fleet units had been placed in service with estimated residual values decreased by 10% of the original cost, for example from 55% to 45% (with specialty containment residual values remaining at 0%), depreciation expense would have been approximately $3.2 million higher for the year ended December 31, 2016. If our rental fleet units had been placed in service with estimated residual values increased by 10% of the original cost, for example, from 55% to 65% for steel storage containers and from 0% to 10% for specialty containment, our depreciation expense would have been lower by approximately $5.0 million, for the year ended December 31, 2016.

Insurance Reserves. We maintain insurance coverage for our operations and employees with appropriate aggregate, per occurrence and deductible limits as we reasonably determine is necessary or prudent considering current operations and historical experience. The majority of these coverages have large deductible programs which allow for potential improved cash flow benefits based on our loss control efforts, while guarantying a maximum premium liability.

Our employee group health insurance program is a self-insured program with individual and aggregate stop loss limits. The insurance provider is responsible for funding all claims in excess of the calculated monthly maximum liability. This calculation is based on a variety of factors including the number of employees enrolled in the plan. Actual results may vary from estimates based on our actual experience at the end of the plan policy periods based on the carrier’s loss predictions and our historical claims data.

We expense the deductible portion of the individual claims. However, we generally do not know the full amount of our exposure to a deductible in connection with any particular claim during the fiscal period in which the claim is incurred and for which we must make an accrual for the deductible expense. We make these accruals based on a combination of the claims development experience of our staff and our insurance companies, and, at year end, the accrual is reviewed and adjusted, in part, based on an independent actuarial review of historical loss data and using certain actuarial assumptions followed in the insurance industry. A high degree of judgment is required in developing these estimates of amounts to be accrued, as well as in connection with the underlying assumptions. In addition, our assumptions will change as our loss experience is developed. All of these factors have the potential for significantly impacting the amounts previously reserved with respect to anticipated deductible expenses and we may be required in the future to increase or decrease amounts previously accrued.

Income Taxes. In preparing our consolidated financial statements, we recognize income taxes in each of the jurisdictions in which we operate. For each jurisdiction, we estimate the actual amount of taxes currently payable or receivable as well as deferred tax assets and liabilities attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred income tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which these temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.

A valuation allowance is provided for those deferred tax assets for which it is more likely than not that the related benefits will not be realized. In determining the amount of the valuation allowance, we consider estimated future taxable income as well as feasible tax planning strategies in each jurisdiction. If we determine that we will not realize all or a portion of our deferred tax assets, we will increase our valuation allowance with a charge to income tax expense. Conversely, if we determine that we will ultimately be able to realize all or a portion of the related benefits for which a valuation allowance has been provided, all or a portion of the related valuation allowance will be reduced with a credit to income tax expense.

The majority of our deferred tax asset relates to federal net operating loss carryforwards that have future expiration dates. Management believes that adequate future taxable income will be generated through future operations, or through available tax planning strategies to recover the unreserved portion of these assets. However, given that the federal net operating loss carryforwards that give rise to the deferred tax asset expire over 7 years beginning in 2028, there could be changes in management’s judgment in future periods with respect to the recoverability of these assets.

Tax regulations within the various jurisdictions within which we operate are subject to interpretation of the related tax laws and regulations and require the application of significant judgment. Our income taxes are subject to examination by federal, state and foreign tax authorities. There may be differing interpretations of tax laws and regulations, and as a result, disputes may arise with these tax authorities involving the timing and amount of deductions and allocation of income.

See additional information regarding income taxes in Note 7 to the accompanying financial statements.

Impact of Foreign Currency Rate Changes. We currently have operations outside the U.S., and we bill those customers primarily in their local currency, which is subject to foreign currency rate changes. Our operations in Canada are billed in the Canadian dollar and operations in the U.K. are billed in Pound Sterling. We are exposed to foreign exchange rate fluctuations as the financial results of our non-U.S. operations are translated into U.S. dollars. The impact of foreign currency rate changes has historically been insignificant with our Canadian operations, but we have more exposure to volatility with our

U.K. operations. We do not currently hedge our currency transaction or translation exposure, nor do we have any current plans to do so.

As a result of Brexit, the global markets and currencies have been adversely impacted, including volatility in the value of the Pound Sterling as compared to the U.S. dollar. Volatility in exchange rates is expected to continue in the short term as the U.K. negotiates its exit from the E.U. In order to help minimize our exchange rate gain and loss volatility, we finance our U.K. entities through our revolving credit facility, which allows us, at our option, to borrow funds locally in Pound Sterling denominated debt. In the longer term, any impact from Brexit on us will depend, in part, on the outcome of tariff, trade, regulatory and other negotiations. Although it is unknown what the result of those negotiations will be, it is possible that new terms may adversely affect our operations and financial results.

We have audited the accompanying consolidated balance sheets of Mobile Mini, Inc. and subsidiaries (the Company) as of December 31, 2016 and 2015, and the related consolidated statements of income, comprehensive income (loss), stockholders’ equity, and cash flows for each of the years in the three-year period ended December 31, 2016. We also have audited Mobile Mini, Inc.’s internal control over financial reporting as of December 31, 2016, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Mobile Mini, Inc.’s management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying “Report of Management on Internal Control over Financial Reporting”. Our responsibility is to express an opinion on these consolidated financial statements and an opinion on the Company’s internal control over financial reporting based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the consolidated financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect 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.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Mobile Mini, Inc. and subsidiaries as of December 31, 2016 and 2015, and the results of their operations and their cash flows for each of the years in the three-year period ended December 31, 2016, in conformity with U.S. generally accepted accounting principles. Also in our opinion, Mobile Mini, Inc. maintained, in all material respects, effective internal control over financial reporting as of December 31, 2016, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

Mobile Mini, Inc., a Delaware corporation, is a leading provider of portable storage and specialty containment solutions. In these notes, the terms “Mobile Mini,” the “Company,” “we,” “us,” and “our” refer to Mobile Mini, Inc. In November 2014, we entered into a Stock Purchase Agreement to acquire Gulf Tanks Holdings (“GTH”), Inc., the parent company of Houston, Texas-based Evergreen Tank Solutions (“ETS”). The transaction, referred to as the “ETS Acquisition,” closed on December 10, 2014. See additional information regarding the acquisition in Note 3. On May 15, 2015, we closed a transaction to sell our wood mobile offices within our North American portable storage segment for a cash price of $92.0 million, less associated assumed liabilities. See additional information regarding the divestiture in Note 4.

At December 31, 2016, we have a fleet of portable storage and office units operating throughout the U.S., Canada and the U.K. serving a diversified customer base, including large and small retailers, construction companies, medical centers, schools, utilities, distributors, the military, hotels, restaurants, entertainment complexes and households. These customers use our products for a wide variety of applications, including the storage of retail and manufacturing inventory, construction materials and equipment, documents and records and other goods. We also have a fleet of specialty containment products, concentrated in the Gulf Coast region of the U.S., including liquid and solid containment units, serving a specialty sector in the industry. Specialty products are leased primarily to chemical, refinery, oil and natural gas drilling, mining and environmental service customers.

The consolidated financial statements include the accounts of Mobile Mini and our wholly owned subsidiaries. We do not have any subsidiaries in which we do not own 100% of the outstanding stock. All significant intercompany balances and transactions have been eliminated.

The preparation of financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the amounts reported in the accompanying consolidated financial statements and the notes to those statements. Actual results could differ from those estimates. Significant estimates affect the calculation of depreciation and amortization, the calculation of the allowance for doubtful accounts, the analysis of goodwill and long-lived assets for potential impairment and certain accrued liabilities.

We consider all highly liquid instruments with insignificant interest rate risk and with maturities of three months or less at purchase to be cash equivalents.

Receivables are stated net of an allowance for doubtful accounts. We estimate the amount of customer receivables that are uncollectible and record an estimated provision for bad debts through a charge to operations. The provision is based on historical collection experience and evaluation of past-due accounts. Specific accounts are written off against the allowance when management determines the account is uncollectible. We require a security deposit on most leased office units to cover the cost of damages or unpaid balances, if any. Our provision for doubtful accounts was less than 1.5% of total revenues in the years ended December 31, 2016, 2015 and 2014.

The information presented in the table below reflects the activity in the allowance for doubtful accounts during the periods presented.

Financial instruments which potentially expose us to concentrations of credit risk consist primarily of receivables. Concentration of credit risk with respect to receivables is limited due to our large number of customers spread over a broad geographic area in many industry sectors. No single customer accounts for more than 15% of our receivables at December 31, 2016 and 2015. Receivables related to sold units are generally secured by the product sold to the customer. We typically have the right to repossess rented portable storage units, including any customer goods contained in the unit, following non-payment of rent.

Inventories are valued at the lower of cost (principally on a standard cost basis which approximates the first-in, first-out method) or net realizable value. Raw materials and supplies principally consist of raw steel, wood, glass, paint, vinyl and other assembly components used in manufacturing and remanufacturing processes, and to a lesser extent, parts used for internal maintenance and ancillary items held for sale in our specialty containment segment. Work-in-process primarily represents partially assembled units pre-sold or for use as fleet. Finished portable storage units primarily represent purchased or assembled containers held in inventory until the container is either sold as is, remanufactured and sold, or remanufactured and deployed as rental fleet. Inventories at December 31 consisted of the following:

Rental fleet is capitalized at cost and depreciated over the estimated useful life of the unit using the straight-line method. Rental fleet is depreciated whether or not it is out on rent. Capitalized cost of rental fleet includes the price paid to acquire the unit and freight charges to the location when the unit is first placed in service, and when applicable, the cost of manufacturing or remanufacturing, which includes the cost of customizing units. Ordinary repair and maintenance costs are charged to operations as incurred.

Property, plant and equipment are stated at cost, net of accumulated depreciation and amortization. Depreciation is recorded using the straight-line method over the assets’ estimated useful lives. Our depreciation expense related to property, plant and equipment for 2016, 2015 and 2014 was $25.1 million, $20.2 million and $15.1 million, respectively. Normal repairs and maintenance to property, plant and equipment are expensed as incurred. When property or equipment is retired or

sold, the net book value of the asset, reduced by any proceeds, is charged to gain or loss on the disposal of property, plant and equipment and is included in rental, selling and general expenses in the Consolidated Statements of Income.

We capitalize qualifying computer software costs incurred during the application development stage for internally developed software. Additionally, we capitalize qualifying costs incurred for upgrades and enhancements to existing software that result in additional functionality. Costs related to preliminary project planning activities, post-implementation activities, maintenance and minor modifications are expensed as incurred. Internal-use software is amortized on a straight line basis over its estimated useful life. Capitalized software development costs are included in property, plant and equipment. As of December 31, 2016 and 2015, we had $35.0 million and $23.5 million, respectively, of capitalized software, net of accumulated depreciation, included in property, plant and equipment. Of the $35.0 million of capitalized software, $31.7 million related to the development of our new ERP system, which was executed in stages in 2016.

Deferred financing costs are included in other assets in the Consolidated Balance Sheet and consist of the costs of obtaining long-term financing. These costs are amortized over the term of the related debt, using the straight-line method, which approximates the effective interest method. Amortization expense for deferred financing costs was approximately $2.0 million, $3.1 million and $2.8 million in 2016, 2015 and 2014, respectively. As discussed in Note 6, we entered into the Credit Agreement in December 2015, resulting in the capitalization of $4.6 million in third-party and lender fees. In addition, in 2015, we wrote off $0.9 million of deferred financing costs related to the prior credit agreement. As of December 31, 2016, $5.6 million of the total $10.4 million unamortized deferred financing costs, related to the Credit Agreement.

Also as discussed in Note 6, in 2016 we issued $250.0 million aggregate principal amount of the 2024 Notes and capitalized $5.2 million of deferred financing costs. Proceeds from the issuance of the 2024 Notes were used in part to redeem $200.0 million in aggregate principal amount of the 2020 Notes. As a result of the redemption of the 2020 Notes during the current-year period, we wrote off $2.3 million of previously deferred costs that had not yet been amortized.

The annual amortization of deferred financing costs is expected to be as follows (in thousands):

For acquired businesses, we record assets acquired and liabilities assumed at their estimated fair values on the respective acquisition dates. Based on these values, the excess purchase prices over the fair value of the net assets acquired is recorded as goodwill. Of the $703.6 million total goodwill at December 31, 2016, $468.5 million related to the North America portable storage segment, $53.9 million related to the U.K. portable storage segment and $181.2 million related to the specialty containment segment.

Some factors management considers important which could indicate an impairment review include the following:

Management may choose to assess qualitative factors to determine if it is more-likely-than-not that goodwill might be impaired and whether or not to perform the two-step goodwill impairment test. When we review goodwill for impairment utilizing a two-step process, the first step of the impairment test requires a comparison of the fair value of each of our reporting unit’s net assets to the respective carrying value of net assets. If the carrying value of a reporting unit’s net assets is less than its fair value, no indication of impairment exists and a second step is not performed. If the carrying amount of a reporting unit’s net assets is higher than its fair value, there is an indication that an impairment may exist and a second step must be performed. If the second step is necessary, management is required to determine the implied fair value of the goodwill and compare it to the carrying value of the goodwill. The fair value of the reporting units would be assigned to the respective assets and liabilities of each reporting unit as if the reporting units had been acquired in separate and individual business combinations and the fair value of the reporting units was the price paid to acquire the reporting units. The excess of the fair value of the reporting units over the amounts assigned to their respective assets and liabilities is the implied fair value of goodwill. If the carrying amount of the reporting unit’s goodwill is greater than the implied fair value of its goodwill, an impairment loss must be recognized for the difference.

In assessing the fair value of the reporting units, management considers both the market approach and the income approach. Under the market approach, the fair value of the reporting unit is based on quoted market prices of companies comparable to the reporting unit being valued. Under the income approach, the fair value of the reporting unit is based on the present value of estimated cash flows. The income approach is dependent on a number of significant management assumptions, including estimated future revenue growth rates, gross margins on sales, operating margins, capital expenditures, tax payments and discount rates. Each approach is given equal weight in arriving at the fair value of the reporting unit.

As of December 31, 2016, management assessed qualitative factors and determined it is more likely than not each of the reporting unit’s assigned goodwill had estimated fair values greater than the respective reporting unit’s individual net asset carrying values; therefore, the two step impairment test was not performed.

In connection with our goodwill impairment test that was conducted as of December 31, 2015, we bypassed the qualitative assessment for each of our reporting units and proceeded directly to the first step of the goodwill impairment test. Our goodwill impairment testing as of this date indicated that both of our portable storage reporting units and our specialty containment reporting unit had estimated fair values which substantially exceeded their respective carrying amounts. The second step of the impairment test was not required for any of the reporting units.

The following table shows the activity and balances related to goodwill from January 1, 2015 to December 31, 2016:

Intangible assets are amortized over the estimated useful life of the asset utilizing a method which reflects the estimated pattern in which the economic benefits will be consumed. Customer relationships are amortized based on the estimated attrition rates of the underlying customer base, other intangibles are amortized using the straight-line method.

The following table reflects balances related to intangible assets for the years ended December 31:

Amortization expense for amortizable intangibles was approximately $6.4 million, $6.0 million and $1.6 million in 2016, 2015 and 2014, respectively. See information regarding intangibles acquired in conjunction with company acquisitions in Note 3. Based on the carrying value at December 31, 2016, future amortization of intangible assets is expected to be as follows for the years ended December 31 (in thousands):

Our rental fleet, property, plant and equipment, and finite-lived intangibles are reviewed for impairment whenever events or changes in circumstances indicate the carrying amount of such assets may be impaired. (See potential impairment indicators under “Goodwill” above). If this review indicates the carrying value of these assets will not be recoverable, as measured based on estimated undiscounted cash flows over their remaining life, the carrying amount would be adjusted to

fair value. The cash flow estimates contain management’s best estimates using appropriate and customary assumptions and projections at the time of evaluation.

During the first quarter of 2015, we entered into discussions regarding the possible sale of our wood mobile offices within our North American portable storage segment. The discussions indicated that the fleet might be sold at an amount below carrying value and we conducted a review for impairment for these long-lived assets as of March 31, 2015. Based on this review, an impairment loss was recorded in the quarter ended March 31, 2015. The total impairment of the wood mobile offices was $64.6 million during 2015. See additional discussion regarding the impairment and the divestiture of the wood mobile offices in Note 4. There were no indicators of further impairment at December 31, 2016 or at December 31, 2015.

We account for acquisitions under the acquisition method. Under the acquisition method of accounting, we record assets acquired and liabilities assumed at their estimated fair market value on the date of acquisition. Goodwill is measured as the excess of the fair value of the consideration transferred over the fair value of the identifiable net assets. Estimated fair values of acquired assets and liabilities is provisional and could change as additional information is received. We finalize valuations as soon as practicable, but not later than one-year from the acquisition date. Any subsequent changes to purchase price allocations results in a corresponding adjustment to goodwill.

Rental revenue is generated from the direct rental of our fleet to our customers, including ancillary revenue such as fleet delivery and pickup. We enter into contracts with our customers to rent equipment based on a monthly rate for our portable storage fleet and a daily, weekly or monthly rate for our specialty containment fleet. Revenues from renting are recognized ratably over the rental period. The rental continues until cancelled by the customer or the Company. Customers may utilize our equipment delivery and pick-up services in conjunction with the rental of equipment, but it is not required. Revenue pursuant to the pick up or delivery of a rented unit is recognized in rental revenue upon completion of the service. When customers are billed in advance, we defer recognition of revenue and record unearned rental revenue at the end of the period. If equipment is returned prior to the end of the contractually obligated period, the excess, if any, between the amount the customer is contractually required to pay, over the cumulative amount of revenue recognized to date, is recognized as incremental revenue upon return.

Cost of sales in our consolidated statements of income includes the costs for units we sell, and to a lesser extent the costs of parts and supplies sold to specialty containment customers. Similar costs associated with units that we rent are capitalized in the balance sheet under “Rental fleet”.

Advertising expense was $3.9 million, $4.1 million and $5.2 million in 2016, 2015 and 2014, respectively. The balance of prepaid advertising costs, which are never amortized more than twelve months, was less than $0.1 million at both December 31, 2016 and 2015.

In preparing our consolidated financial statements, we recognize income taxes in each of the jurisdictions in which we operate. For each jurisdiction, we estimate the actual amount of taxes currently payable or receivable as well as deferred tax assets and liabilities attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred income tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which these temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.

We record uncertain tax positions using a two-step process, whereby (1) we determine whether it is more likely than not that the tax positions will be sustained on the basis of the technical merits of the position and (2) for those tax positions that meet the more-likely-than-not recognition threshold, we recognize the largest amount of tax benefit that is more than 50% likely to be realized upon ultimate settlement with the related tax authority.

The Company recognizes interest and penalties related to unrecognized tax benefits within the interest expense line and other expense line, respectively, in the accompanying Consolidated Statement of Income. Accrued interest and penalties are included within the related liability lines in the Consolidated Balance Sheet.

Basic earnings per share (“EPS”) is calculated by dividing net income by the weighted average number of common shares outstanding during the period. Diluted EPS is calculated under the treasury stock method. Potential common shares included restricted common stock, which is subject to risk of forfeiture, incremental shares of common stock issuable upon the exercise of stock options and vesting of restricted stock awards.

The following table is a reconciliation of net income and weighted-average shares of common stock outstanding for purposes of calculating basic and diluted EPS for the years ended December 31:

Basic weighted average number of common shares outstanding does not include restricted stock awards that had not vested of 0.2 million, 0.2 million and 0.3 million shares in 2016, 2015 and 2014, respectively.

The following table represents the number of stock options and restricted stock awards that were issued or outstanding but excluded in calculating diluted EPS because their effect would have been anti-dilutive for the years ended December 31:

Fair value is the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants. Fair value is a market-based measurement determined by assumptions that market participants would use in pricing an asset or liability. We categorize each of our fair value measurements in one of the following three levels based on the lowest level of input that is significant to the fair value measurement:

Level 1 — Observable inputs such as quoted prices in active markets for identical assets or liabilities;

Level 2 — Observable inputs, other than Level 1 inputs in active markets, that are observable either directly or indirectly; and

Level 3 — Unobservable inputs for which there is little or no market data, which require the reporting entity to develop its own assumptions.

The carrying amounts of cash, cash equivalents, receivables, accounts payable and accrued liabilities approximate fair values based on their short-term nature. The fair values of our revolving credit facility and capital leases are estimated using discounted cash flow analyses, based on our current incremental borrowing rates for similar types of borrowing arrangements. Based on the borrowing rates currently available to us for bank loans with similar terms and average maturities, the fair value of our revolving credit facility debt and capital leases, which are measured using Level 2 inputs, at December 31, 2016 and 2015 approximated their respective book values.

During 2016, we redeemed all $200.0 million aggregate principal amount of our outstanding 7.875% senior notes due December 1, 2020 (“2020 Notes”), and issued $250.0 million aggregate principal amount of 5.875% senior notes due July 1, 2024 (“2024 Notes”). See more information in Note 6. The fair value of our 2020 Notes and 2024 Notes (together, the “Senior Notes”) for the periods presented below is based on their latest sales price at the end of each period obtained from a third-party institution and is Level 2 in the fair value hierarchy as there is not an active market for these Senior Notes.

The Senior Notes are presented on the balance sheet net of debt issuance costs. The gross carrying value and the fair value of the Senior Notes are as follows:

At December 31, 2016 and 2015, we did not have any financial instruments required to be recorded at fair value on a recurring basis.

In the normal course of business, our operations are exposed to fluctuations in interest rates. We have in the past, and may again in the future, address a portion of these risks through a controlled program of risk management that includes the use of derivative financial instruments. The objective of controlling these risks is to limit the impact of fluctuations in interest rates on earnings. At December 31, 2016 and 2015, we did not have any derivative financial instruments.

We calculate the fair value of stock options using the Black-Scholes-Merton option pricing valuation model, which incorporates various assumptions including volatility, expected life and risk-free interest rates. The fair value of restricted stock awards is estimated as the closing price of our common stock on the date of grant. Compensation related to service-based awards are recognized on a straight-line basis over the vesting period, which is generally three to five years. Compensation expense related to performance-based awards is recognized over the implicit service period of the award based on management’s estimate of the probability of the performance criteria being satisfied, adjusted at each balance sheet date. Expense related to performance-based awards that have multiple vesting dates, is recognized using the accelerated attribution approach, whereby each vesting tranche is treated as a separate award for purposes of determining the implicit service period. Share based compensation expense is reduced for forfeitures which are estimated at the time of grant based on historical experience, and revised in subsequent periods if actual forfeitures differ from estimates.

For our non-U.S. operations, the local currency is the functional currency. All assets and liabilities are translated into U.S. dollars at period-end exchange rates and all income statement amounts are translated at the average exchange rate for each month within the year.

Share-Based Compensation. In March 2016, the Financial Accounting Standards Board (“FASB”) issued a standard intended to simplify several areas of accounting for share-based compensation arrangements, including the income tax impact, classification on the statement of cash flows and forfeitures. This standard is effective for annual and interim periods beginning after December 15, 2016. We will implement this standard in the first quarter of 2017.

This standard eliminates the requirement that excess tax benefits be realized before companies can recognize them. As a result, utilizing the modified retrospective method, we expect to record a cumulative-effect adjustment for previously unrecognized excess tax benefits of $18.5 million in the opening balance sheet for 2017, with an offsetting increase to retained earnings (deficit). In addition, the standard allows us to make a policy election to either continue to reduce share-based compensation expense for forfeitures in future periods, or to recognize forfeitures as they occur. We have chosen to record forfeitures as they occur and will record immaterial adjustments to reflect a cumulative-effect adjustment for the difference between the fair value estimate of awards historically expected to be forfeited and the fair value estimate of awards actually forfeited. This standard also requires all excess tax benefits and tax deficiencies associated with the exercise of stock options and vesting of restricted stock to be recorded as income tax expense or benefit. Increases and decreases in the aggregate intrinsic value (or negative value) of such activity could introduce volatility in our effective tax rate. We do not expect the remaining provisions of the new guidance to have a material effect on our consolidated financial statements.

Leases. In February 2016, FASB issued a standard on lease accounting requiring a lessee to recognize assets and liabilities on the balance sheet for leases with lease terms greater than 12 months. This standard is effective for annual and interim periods beginning after December 15, 2018. Early adoption is permitted and the standard requires the use of a modified retrospective transition method. While we are continuing to evaluate all potential impacts of the standard, we do not believe the accounting for our contractual rental revenue will be materially affected by the adoption of this standard. We anticipate the lessee accounting for operating leases under the standard will have a material effect on our statement of financial position.

Simplifying the Presentation of Debt Issuance Costs. In April 2015, FASB issued accounting guidance on the presentation of debt issuance costs in the balance sheet. This standard requires that certain debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by this guidance. We adopted this guidance during 2016. As a result, unamortized debt issuance costs of $4.8 million and $2.4 million as of December 31, 2016 and December 31, 2015, respectively, have been deducted from the carrying amount of the Senior Notes in our balance sheet. Unamortized debt issuance costs related to our revolving credit facility are included in other assets.

Revenue from Contracts with Customers. In May 2014, FASB issued an accounting standard on revenue from contracts with customers. The standard provides a single model for revenue arising from contracts with customers and

supersedes current revenue recognition guidance. The standard requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of goods or services and is effective for annual and interim periods beginning after December 15, 2017. Early adoption is permitted for the annual and interim periods beginning after December 15, 2016, but not prior to that time. The revenue recognition standard permits the use of either the retrospective or cumulative effect transition method.

While we are continuing to assess all potential impacts of the standard, we currently believe the majority of our revenue, as relates to contractual rental revenue, is excluded from the scope of this standard, and the accounting for the remaining revenue streams will not be materially affected. Accordingly, we do not anticipate that the adoption of this standard will have a material impact on our consolidated financial statements. We expect to utilize the modified retrospective adoption and recognize the cumulative effect of initially applying the standard, if any, as an adjustment to the opening balance of retained earnings at the date of initial application.

During the year ended December 31, 2016, we completed three acquisitions of portable storage businesses. One acquisition expanded our business in Dallas, Texas. The other two were in the United Kingdom. The accompanying consolidated financial statements include the operations of the acquired businesses from the dates of acquisition. The aggregate purchase price for the assets acquired were recorded based on their estimated fair values at the date of the acquisitions. We have not disclosed the pro-forma impact of the acquisitions on operations as they were immaterial to our financial position or results of operations in the aggregate.

The components of the purchase price and net assets acquired during the year ended December 31, 2016 are as follows (in thousands):

During the year ended December 31, 2015, we completed two acquisitions of portable storage businesses. These acquisitions expanded our existing operations in the Glasgow, Scotland market, and further strengthened our positions in Knoxville and Chattanooga, Tennessee. The accompanying consolidated financial statements include the operations of the acquired businesses from the dates of acquisition. The aggregate purchase price for the assets acquired were recorded based on their estimated fair values at the date of the acquisitions. We have not disclosed the pro-forma impact of the acquisitions on operations as they were immaterial to our financial position or results of operations in the aggregate.

The components of the purchase price and net assets acquired during the year ended December 31, 2015 (as adjusted in 2016) are as follows (in thousands):

On December 10, 2014, we acquired all of the outstanding equity interests of GTH, the parent company of ETS, referred to as the ETS Acquisition. As a result of the ETS Acquisition, included in our consolidated statements of income for the years ended December 31, 2016, 2015 and 2014 is $98.1 million, $107.3 million and $6.4 million, respectively, of specialty containment revenues and $2.3 million, $11.1 million and $1.1 million, respectively, of income from continuing operations before income tax provision. Direct expenses related to the ETS Acquisition were $2.5 million in the twelve months ended December 31, 2015 and $5.0 million in the fourth quarter of 2014.

Also in 2014, we completed eight other acquisitions of portable storage businesses through both asset purchase and stock purchase agreements. The purchased assets and assumed liabilities were recorded at their estimated fair value at the date of acquisition. Five of these acquisitions expanded our existing operations in North Dakota, North Carolina, Texas, Tennessee, Florida and South Carolina markets. The other three acquisitions created new locations in the Danbury, Connecticut, Fort Wayne, Indiana and Buffalo, New York metropolitan areas.

The accompanying consolidated financial statements include the operations of the acquired businesses from the date of acquisition. The aggregate purchase price for the assets acquired and the liabilities assumed were recorded based on their estimated fair values at the date of each acquisition. Valuations were performed based on available information at the time of acquisition. Estimated fair values of acquired assets and liabilities have changed immaterially as additional information was received.

The components of the purchase price and net assets acquired for 2014 acquisitions are as follows:

Customer relationships acquired in conjunction with the ETS Acquisition were evaluated separately for the wholly owned subsidiary Water Movers, Inc. (“Water Movers”). With input from an independent third party with extensive expertise and experience in this area, we determined lives for the two customer groups based upon historical and expected customer attrition rates, resulting in an expected useful life of 15 years for the Water Movers customer relationships, which were valued at $14.9 million, and an expected useful life of 20 years for the remaining ETS customer relationships, which were valued at $54.3 million. During our assessment, we evaluated annual historical sales data from 2009 through December 2014 for Water Movers, and 2008 through December 2014 for the remaining ETS customers.

The unaudited pro forma financial information is presented for informational purposes only and is not indicative, and should not be relied on as being indicative, of the results of operations that would have been achieved if the acquisition had actually taken place at the beginning of each of the periods presented. The pro forma financial information reflects only the ETS Acquisition, as the remaining acquisitions would not have a material effect on reported results of operations.

The following table summarizes our unaudited consolidated statements of income as if the ETS Acquisition occurred on January 1, 2013:

Our business strategy is to invest in high return, low maintenance, long-lived assets. Wood mobile offices require more maintenance and upkeep than Mobile Mini’s steel containers and steel ground level offices, resulting in lower margins as compared to our other portable storage products and our specialty containment products. During March 2015, we entered into discussions regarding the possible sale of our wood mobile offices within our North American portable storage segment. The discussions indicated that the fleet might be sold at an amount below carrying value.

Based upon the events described above, we conducted a review for impairment for these particular long-lived assets as of March 31, 2015. The review included assumptions of cash flows considering the likelihood of possible outcomes that existed as of the date of the review, including assigning probabilities to these outcomes. Management estimated fair market value for the wood mobile offices based upon purchase price discussions. Based on this review, management determined that the assets were impaired as of March 31, 2015 and an impairment loss was recognized.

On April 16, 2015, we entered into a definitive agreement to sell our wood mobile offices within the North American portable storage segment for a cash price of $92.0 million, less associated deferred revenue and customer deposits of $6.8 million. The net assets were reclassified to held for sale as of that date. The transaction closed on May 15, 2015 and we recorded a net loss.

For the twelve months ended December 31, 2015, the following amounts were recorded for the impairment and divestiture of the wood mobile office fleet:

We also entered into a transition services agreement with the purchaser, whereby we agreed to provide short-term direct services such as transportation and maintenance for the wood mobile offices on behalf of the purchaser, as well as house units on our leased properties and provide certain administrative services such as billing and cash collection during 2015. The revenue related to this agreement is included in other revenue, and the expenses for providing these services are included in rental, selling and general expenses.

Depreciation expense related to our rental fleet for 2016, 2015 and 2014 was $32.3 million, $34.1 million and $22.7 million, respectively. At December 31, 2016 and 2015, all rental fleet units were pledged as collateral under the Credit Agreement. Appraisals on our rental fleet are required by our lenders on a regular basis. The appraisal typically reports no difference in the value of the unit due to the age or length of time it has been in our fleet. Based in part upon our lender’s third-party appraiser who evaluated our fleet as of September 30, 2015, management estimates that the net orderly liquidation appraisal value as of December 31, 2016 was approximately $1.1 billion. Our net book value for this fleet as of December 31, 2016 was $950.1 million.

On December 14, 2015, we entered into the Credit Agreement with Deutsche Bank AG New York Branch, as administrative agent, and other lenders party thereto. The Credit Agreement provides for a five-year, $1.0 billion first lien senior secured revolving credit facility maturing on or before the earlier of (i) December 14, 2020 and (ii) the date that is 90 days prior to the final maturity date of the Senior Notes, if such Senior Notes remain outstanding on such date. The Credit Agreement also provides for the issuance of irrevocable standby letters of credit by U.S.-based lenders in amounts totaling up to $50.0 million, by U.K.-based lenders in amounts totaling up to $20.0 million, and by Canadian-based lenders in amounts totaling up to $20.0 million. The obligations of Mobile Mini and its subsidiary guarantors under the Credit Agreement are secured by a blanket lien on substantially all of our assets.

Availability of borrowings under the Credit Agreement is subject to a borrowing base calculation based upon a valuation of the Company’s eligible accounts receivable, eligible container fleet (including containers held for sale, work-in-process and raw materials) and machinery and equipment, each multiplied by an applicable advance rate or limit. The rental fleet is appraised at least once annually by a third-party appraisal firm and up to 90% of the net orderly liquidation value, as defined in the Credit Agreement, is included in the borrowing base to determine how much the Company may borrow under the Credit Agreement.

The Credit Agreement provides for U.K. borrowings, which are, at the Company’s option, denominated in either Pounds Sterling or Euros, by its U.K. subsidiary based upon a U.K. borrowing base; Canadian borrowings, which are denominated in Canadian dollars, by its Canadian subsidiary based upon a Canadian borrowing base; and U.S. borrowings, which are denominated in U.S. dollars, by the Company based upon a U.S. borrowing base along with any Canadian assets not included in the Canadian subsidiary.

The Credit Agreement also contains customary negative covenants, including covenants that restrict the Company’s ability to, among other things: (i) allow certain liens to attach to the Company’s or its subsidiaries’ assets, (ii) repurchase or pay dividends or make certain other restricted payments on capital stock and certain other securities, or prepay certain indebtedness, (iii) incur additional indebtedness or engage in certain other types of financing transactions, and (iv) make acquisitions or other investments. In addition, we must comply with a minimum fixed charge coverage ratio of 1.00 to 1.00 as of the last day of each quarter, upon the minimum availability amount under the Credit Agreement falling below the greater of (y) $90 million and (z) 10% of the lesser of the then total revolving loan commitment and aggregate borrowing base. As of December 31, 2016, we were in compliance with the minimum borrowing availability threshold set forth in the Credit Agreement and, therefore, are not subject to any financial maintenance covenants.

The weighted average interest rate under the lines of credit was approximately 2.1% in 2016 and 2.2% in 2015. The average outstanding balance was approximately $652.0 million and $670.4 million during 2016 and 2015, respectively. At December 31, 2016, the Company had approximately $641.2 million of borrowings outstanding and $354.3 million of additional borrowing availability under the Credit Agreement, based upon borrowing base calculations as of such date.

On May 9, 2016, we issued $250.0 million aggregate principal amount of the 2024 Notes at an initial offering price of 100% of their face value. The net proceeds from the sale of the 2024 Notes were used to (i) redeem all $200.0 million aggregate principal amount of our outstanding 2020 Notes at a redemption price of 103.938% of the principal amount thereof plus accrued and unpaid interest to, but not including, the redemption date of June 8, 2016, (ii) repay a portion of the indebtedness outstanding under our asset-based revolving credit facility, and (iii) pay fees and expenses related to the offering of the 2024 Notes.

As a result of the redemption of the 2020 Notes during the current-year period, we recognized $9.2 million in debt extinguishment expense, consisting of $7.9 million in debt redemption premiums and $1.3 million in contractually required interest above the amount payable prior to the redemption. Additionally, we wrote off $2.3 million of previously deferred costs associated with the 2020 Notes that had not yet been amortized.

At December 31, 2016 and 2015, obligations under capital leases for certain real property, transportation, technology and office related equipment were $50.7 million and $38.3 million, respectively. Certain of the lease agreements provide us with a purchase option at the end of the lease term. The leases have been capitalized using interest rates primarily ranging from approximately 1.7% to 13.0% and are secured by the property and equipment under lease.

Assets recorded under capital lease obligations totaled approximately $62.6 million as of December 31, 2016 and $44.5 million as of December 31, 2015. Related accumulated amortization totaled approximately $16.0 million as of December 31, 2016 and $7.6 million as of December 31, 2015. The assets acquired under capital leases and related accumulated amortization are included in property, plant and equipment, net, in the Consolidated Balance Sheets. The related amortization is included in depreciation and amortization expense in the Consolidated Statements of Income.

Future minimum capital lease payments at December 31, 2016 are as follows (in thousands):

The scheduled maturity for debt obligations for balances outstanding at December 31, 2016 are as follows:

A reconciliation of the U.S. federal statutory rate to our effective tax rate for the years ended December 31 is as follows (1):

The components of the net deferred tax liability at December 31 are approximately as follows:

A net deferred tax liability of approximately $18.5 million and $17.1 million related to our U.K. operations has been combined with the net deferred tax liabilities of our U.S. operations in the Consolidated Balance Sheets at December 31, 2016 and 2015, respectively.

At December 31, 2016, we had U.S. federal net operating loss carryforwards on our federal tax return of approximately $236.6 million, which expire if unused from 2028 to 2034. At December 31, 2016, we had net operating loss carryforwards on the various states’ tax returns in which we operate totaling $123.6 million, which expire if unused from 2017 to 2035.

Management evaluates the ability to realize our deferred tax assets on a quarterly basis and adjusts the amount of our valuation allowance if necessary. Over the past three years, we have generated $149.2 million of federal taxable income. Management currently believes that adequate future taxable income will be generated through future operations, or through available tax planning strategies to recover the unreserved portion of these deferred tax assets.

For income tax purposes, deductible compensation related to share-based awards is based on the value of the award when realized, which may be different than the compensation expense recognized by us in our financial statements, which is based on the award value on the date of grant. The difference between the value of the award upon grant, and the value of the award when ultimately realized, creates either additional tax benefits or a tax shortfall.

Tax benefits resulting from tax deductions in excess of the compensation cost recognized for share-based awards are recognized as increases to additional paid in capital and as financing cash flows, only if an incremental income tax benefit would be realized after considering all other tax attributes presently available to us. We have not recognized excess tax benefits in 2016, 2015 or 2014, because we have not paid U.S. federal income taxes in those years.

Tax shortfalls, which occur when the tax deduction for share-based awards is less than the compensation cost recognized, are recorded as a reduction to additional paid in capital to the extent that, cumulatively, the shortfalls do not exceed the cumulative excess tax benefits recognized (including excess tax benefits not yet recognized in additional paid in capital). Should cumulative tax shortfalls exceed cumulative excess tax benefits, the difference would be reflected as additional tax expense in our financial statements.

At December 31, 2016 and 2015, our net operating losses carrying forward for tax return purposes include $18.5 million and $17.7 million, respectively, of excess tax benefits from employee stock awards. See Note 2 for a discussion of the impact of recently issued accounting standards on excess tax benefits.

A deferred U.S. tax liability has not been provided on the undistributed earnings of certain foreign subsidiaries because it is our intent to permanently reinvest such earnings. Undistributed earnings of foreign subsidiaries, which have been or are intended to be permanently invested, aggregated approximately $62.4 million and $47.2 million as of December 31, 2016 and 2015, respectively. The estimated unrecognized deferred tax liability associated with these temporary differences was approximately $11.5 million as of December 31, 2016.

As a result of stock ownership changes during the years presented, it is possible that we have undergone a change in ownership for federal income tax purposes, which can limit the amount of net operating loss currently available as a deduction. We have determined that even if such an ownership change has occurred, it would not impair the realization of the deferred tax asset resulting from the federal net operating loss carryover.

We paid income and franchise taxes of approximately $1.8 million in 2016, $4.9 million in 2015 and $1.1 million in 2014. These amounts are lower than the recorded expense in the years due to net operating loss carryforwards and general business credit utilization.

We are subject to taxation in the U.S. federal jurisdiction, as well as various U.S. state and foreign jurisdictions. We have identified our U.S. federal tax return as our “major” tax jurisdiction. As of December 31, 2016, we are no longer subject to examination by U.S. federal tax authorities for years prior to 2013, to examination for any U.S. state taxing authority prior to 2011, or to examination for any foreign jurisdictions prior to 2012. All subsequent periods remain open to examination.

Uncertain tax positions are recognized and measured using a two-step approach. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation process, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon ultimate settlement.

As of December 31, 2016, we had approximately $5.9 million of gross unrecognized tax benefits, of which, none would affect our effective tax rate if recognized. A reconciliation of the beginning and ending balance of unrecognized tax benefits is as follows:

Of the amount of unrecognized tax benefits outstanding at December 31, 2016, all of the amount is expected to reverse within the next twelve month.

Our policy for recording interest and penalties associated with uncertain tax positions is to record such items as a component of income before taxes. Penalties and associated interest costs, if any, are recorded in rental, selling and general expenses in our Consolidated Statements of Income.

With the ETS Acquisition, we acquired its wholly owned subsidiary, Water Movers, which has two real property leases with an entity partly owned by Michael Watts, a member of our board of directors (“Board”). These leases began in 2013, prior to the ETS Acquisition, and expire in 2023. Rental payments under these leases are currently approximately $18,000 per month. Any future renewals of these leases will be approved by the Board as related party transactions. It is our intention not to enter into any additional related person transactions.

We have historically awarded stock options and restricted stock awards for employees and non-employee directors as a means of attracting and retaining quality personnel and to align employee performance with stockholder value. Stock option plans are approved by our stockholders and administered by the compensation committee of the Board. The current plan

allows for a variety of equity programs designed to provide flexibility in implementing equity and cash awards, including incentive stock options, nonqualified stock options, restricted stock awards, restricted stock units, stock appreciation rights, performance stock, performance units and other stock-based awards. Participants may be granted any one of the equity awards or any combination. We do not award stock options with an exercise price below the market price of the underlying securities on the date of award. As of December 31, 2016, 2.0 million shares are available for future grants. Generally stock options have contractual terms of ten years.

Service-based awards. We grant share-based compensation awards that vest over time subject to the employee rendering service over the vesting period. The majority of the service–based awards vest in equal annual installments over a period of three to five years. The expense for service-based awards is expensed ratably over the full service period of the grant.

Performance-based awards. All stock options granted in 2016 vest contingently over a three-year period upon the achievement of certain performance criteria related to the operating performance of the Company. Participants may earn from 50% to 200% of the target options awarded assuming at least minimum targets are achieved, and depending on actual results. If minimum targets are not achieved no options are vested. Options which are not vested in any given year are forfeited, but the subsequent years are not affected. For certain awards granted prior to 2016, there is also a cumulative performance objective.

Expense related to performance-based awards that have multiple vesting dates, is recognized using the accelerated attribution approach, whereby each vesting tranche is treated as a separate award for purposes of determining the implicit service period. The accelerated attribution approach results in a higher expense during the earlier years of vesting.

Non-employee director awards. Each non-employee director serving on the Board receives an automatic award of shares of Mobile Mini’s common stock annually. These awards vest 100% when granted. For the years ended December 31, 2016, 2015 and 2014, $0.8 million, $0.8 million and $0.9 million, respectively, of expense was recognized related to these grants.

Share-based compensation expense. The following table summarizes our share-based compensation for the years ended December 31:

As of December 31, 2016, total unrecognized compensation cost related to stock option awards was approximately $2.7 million and the related weighted-average period over which it is expected to be recognized is approximately 1.1 years. As of December 31, 2016, the unrecognized compensation cost related to restricted stock awards was approximately $5.0 million, which is expected to be recognized over a weighted-average period of approximately 2.3 years.

Stock options. The fair value of each stock option award is estimated on the date of the grant using the Black-Scholes-Merton option pricing model which requires the input of assumptions. We estimate the risk-free interest rate based on the U.S. Treasury security rate in effect at the time of the grant. The expected life of the options, volatility and dividend rates are estimated based on our historical data. The following are the key assumptions used for the period noted:

The following table summarizes stock option activity for the years ended December 31 (share amounts in thousands):

The stock options granted in 2016 are performance-based and are shown in the table at the target award. The actual amount of shares that ultimately vest depends on achievement of performance criteria. As of December 31, 2016, approximately 0.5 million performance-based stock options remain unvested. Shares contingently vesting based upon 2016 performance criteria did not achieve the minimum vesting target criteria, resulting in the forfeiture of 0.2 million shares in January 2017. The shares are included as outstanding in the tables above and below.

The aggregate intrinsic value of options exercised during the period ended December 31, 2016, 2015 and 2014 was $0.1 million, $0.8 million and $2.9 million, respectively. The weighted average fair value of stock options granted was $6.64, $8.43 and $10.46 for the years ended December 31, 2016, 2015 and 2014, respectively.

Restricted Stock Awards. The fair value of restricted stock awards is estimated as the closing price of our common stock on the date of grant. A summary of restricted stock activity is as follows (share amounts in thousands):

The total fair value of restricted stock awards that vested in 2016, 2015 and 2014 were $3.8 million, $4.8 million and $5.0 million, respectively. As of December 31, 2016, approximately 11,000 performance-based restricted stock awards remain unvested.

In the U.S. we sponsor 401(k) retirement plans designed to provide tax-deferred retirement benefits to employees in accordance with the provisions of Section 401(k) of the Internal Revenue Code. We also sponsor defined contribution programs in the U.K., and have a Registered Retirement Savings Plan regulated by Canadian law.

Under the U.S. and Canadian plans we match a percentage of the participants’ contributions up to a specified amount. Under the U.K. plan, we contribute a percentage of each participant’s annual salary to the plan and, depending on the plan, employees may also be required to contribute a percentage of their annual salary into the plan. In the U.S. plans Company matches vest over a period of two to five years, while Company matches for U.K. and Canadian employees are immediately vested. Company contributions to all these benefit plans totaled approximately $0.9 million, $1.1 million and $0.7 million in 2016, 2015 and 2014, respectively. In each of the three years ending December 31, 2016, 2015 and 2014, we incurred approximately $32,000, $51,000 and $34,000, respectively, for administrative costs for these programs.

We lease our corporate offices and other properties and operating equipment from third parties under noncancelable operating leases. Rent expense under these agreements was approximately $22.3 million, $22.7 million and $21.3 million for the years ended December 31, 2016, 2015 and 2014, respectively.

As of December 31, 2016, contractual commitments associated with lease obligations are as follows:

Future minimum lease payments under restructured non-cancelable operating leases as of December 31, 2016, are included in accrued liabilities in the Consolidated Balance Sheet. See Note 13 for a further discussion on restructuring related commitments.

We maintain insurance coverage for our operations and employees with appropriate aggregate, per occurrence and deductible limits as we reasonably determine is necessary or prudent considering current operations and historical experience. The majority of these coverages have large deductible programs which allow for potential improved cash flow benefits based on our loss control efforts, while guarantying a maximum premium liability.

from estimates based on our actual experience at the end of the plan policy periods based on the carrier’s loss predictions and our historical claims data.

We expense the deductible portion of the individual claims. However, we generally do not know the full amount of our exposure to a deductible in connection with any particular claim during the fiscal period in which the claim is incurred and for which we must make an accrual for the deductible expense. We make these accruals based on a combination of the claims development experience of our staff and our insurance companies, and, at year end, the accrual is reviewed and adjusted, in part, based on an independent actuarial review of historical loss data and using certain actuarial assumptions followed in the insurance industry. A high degree of judgment is required in developing these estimates of amounts to be accrued, as well as in connection with the underlying assumptions. In addition, our assumptions will change as our loss experience is developed. All of these factors have the potential for significantly impacting the amounts previously reserved in respect of anticipated deductible expenses and we may be required in the future to increase or decrease amounts previously accrued.

Our worker’s compensation, auto and general liability insurance are purchased under large deductible programs. Our current per incident deductibles are: worker’s compensation $250,000, auto $500,000 and general liability $50,000. Under our various insurance programs, we have collective reserves recorded in accrued liabilities of $4.2 million and $3.8 million at December 31, 2016 and 2015, respectively.

In connection with the issuance of our insurance policies, we have provided our various insurance carriers approximately $4.5 million in letters of credit as of December 31, 2016.

We are a party to various claims and litigation in the normal course of business. Our current estimated range of liability related to various claims and pending litigation is based on claims for which our management can determine that it is probable that a liability has been incurred and the amount of loss can be reasonably estimated. Because of the uncertainties related to both the probability of incurred and possible range of loss on pending claims and litigation, management must use considerable judgment in making reasonable determination of the liability that could result from an unfavorable outcome. As additional information becomes available, we will assess the potential liability related to our pending litigation and revise our estimates. Such revisions in our estimates of the potential liability could materially impact our results of operation. We do not anticipate the resolution of such matters known at this time will have a material adverse effect on our business or consolidated financial position.

During the twelve months ended December 31, 2016 we paid cash dividends of $0.82 per share for a total of $36.4 million. Each future quarterly dividend payment is subject to review and approval by the Board. In addition, our Credit Agreement contains restrictions on the declaration and payment of dividends.

During the twelve months ended December 31, 2016, we purchased approximately 0.4 million shares of our common stock at a cost of $10.8 million under the authorized share repurchase program, and approximately $78.2 million is available for repurchase as of December 31, 2016. In addition, we withheld approximately 16,000 shares of stock from employees, for an approximate value of $0.5 million, upon vesting of share awards to satisfy minimum tax withholding obligations. These shares were not acquired pursuant to the share repurchase program.

During the twelve months ended December 31, 2015, we purchased approximately 1.7 million shares of our common stock at a cost of $61.0 million under the authorized share repurchase program. In addition, we withheld approximately 21,000 shares of stock from employees, for an approximate value of $0.8 million, upon vesting of share awards to satisfy minimum tax withholding obligations. These shares were not acquired pursuant to the share repurchase program.

During the twelve months ended December 31, 2014, we purchased approximately 0.6 million shares of our common stock at a cost of $25.0 million under the authorized share repurchase program. In addition, we withheld approximately 25,000 shares of stock from employees, for an approximate value of $1.0 million, upon vesting of share awards to satisfy minimum tax withholding obligations. These shares were not acquired pursuant to the share repurchase program.

We have undergone restructuring actions to align our business operations. The restructuring costs in 2016 resulted primarily to the continuation of projects initiated in prior years.

For the twelve months ended December 31, 2016 and 2015, we recognized $2.0 million and $19.7 million, respectively, in expenses related to activities associated with the integration of ETS into the existing Mobile Mini infrastructure.

As part of the integration process, in 2015, as the Company was finalizing locations in Southern California for combined portable storage and specialty containment equipment operations, we determined that certain of our current locations in Southern California would either not be optimal or available to accommodate efficient operations and provide desired proximity to our combined customer base. To accommodate the needs of the planned combined operations, the Company is leasing new property, exiting certain properties and has abandoned approximately 5,000 units of the portable storage fleet in Southern California at the legacy yards. This abandonment resulted in $13.7 million of restructuring expense in the fourth quarter of 2015, representing the write-down of this fleet to zero value.

Other costs related to performance of the integration include $0.5 million and $4.6 million for severance and benefits, for the years ended December 31, 2016 and 2015, respectively. Included in the severance and benefits is $0.2 million and $1.6 million of share-based compensation, for each year respectively. In 2015, we also recognized $1.4 million for the write-off and loss on sale of property, plant and equipment, related to the integration.

We recognized $3.3 million and $0.8 million during the twelve months ended December 31, 2016 and 2015, respectively, related to the abandonment of yards, or portions of yards, as well as related fleet and other costs due to our move away from the wood mobile office business.

The 2014 restructuring costs resulted from the restructuring of U.K. locations, including the sale of the Belfast, North Ireland location. In addition, the Company’s field management and sales force structures in North America were realigned in 2014 along with other organizational changes.

The following table details accrued restructuring obligations (included in accrued liabilities in the Consolidated Balance Sheets) and related activity for the years ended December 31, 2016, 2015 and 2014:

The following amounts are included in restructuring expense for the years ended December 31:

Prior to the ETS Acquisition, our operations were comprised of two reportable segments: North America and the U.K., both of which offer portable storage solutions. Discrete financial data on each of our products is not available and it would be impractical to collect and maintain financial data in such a manner. As a result of the ETS Acquisition, we established a new specialty containment reportable segment. ETS operations are included in our results of operations for all of 2016 and 2015, and the portion of 2014 subsequent to the acquisition date, which is less than one month. The results for each segment are reviewed discretely by our chief operating decision maker.

We operate in the U.S., U.K. and Canada. All of our locations operate in their local currency and, although we are exposed to foreign exchange rate fluctuation in foreign markets where we rent and sell our products, we do not believe such exposure will have a significant impact on our results of operations. Revenues recognized by our U.S. locations were $424.4 million, $438.4 million and $353.2 million for the twelve months ended December 31, 2016, 2015 and 2014, respectively.

The following tables set forth certain information regarding each of our reportable segments for the years ended December 31, 2016, 2015 and 2014:

Included in the Consolidated Balance Sheet are assets in the U.S. of $1.6 billion as of both December 31, 2016 and 2015.

The following table sets forth certain unaudited selected consolidated financial information for each of the four quarters in the years ended December 31, 2016 and 2015. In management’s opinion, this unaudited consolidated quarterly selected information has been prepared on the same basis as the audited consolidated financial statements and includes all necessary adjustments, consisting only of normal recurring adjustments, which management considers necessary for a fair presentation when read in conjunction with the Consolidated Financial Statements and notes. We believe these comparisons of consolidated quarterly selected financial data are not necessarily indicative of future performance.

Quarterly EPS may not total to the fiscal year EPS due to the weighted average number of shares outstanding at the end of each period reported and rounding.

The following tables reflect the condensed consolidating financial information of our subsidiary guarantors of the Senior Notes and our non-guarantor subsidiaries. Separate financial statements of the subsidiary guarantors are not presented because the guarantee by each 100% owned subsidiary guarantor is full and unconditional, joint and several, subject to customer exceptions, and management has determined that such information is not material to investors.

On January 31, 2017, the Board authorized and declared a cash dividend to all our common stockholders of $0.227 per share of common stock, payable on March 15, 2017 to stockholders of record as of the close of business March 1, 2017. Each future quarterly dividend payment is subject to review and approval by the Board.

As of the end of the period covered by this Annual Report on Form 10-K, we carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and our Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act. Based on that evaluation, our Chief Executive Officer and our Chief Financial Officer concluded that, as of the end of the period covered by this Annual Report on Form 10-K, the Company’s disclosure controls and procedures, were effective such that the information relating to the Company required to be disclosed in our SEC reports (i) is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and (ii) is accumulated and communicated to the Company’s management, including our Chief Executive Officer and our Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

Our management is responsible for establishing and maintaining adequate internal control over financial reporting for the Company. Internal control over financial reporting is a process to provide reasonable assurance regarding the reliability of our financial reporting for external purposes in accordance with accounting principles generally accepted in the United States of America. Internal control over financial reporting includes maintaining records that in reasonable detail accurately and fairly reflect our transactions; providing reasonable assurance that transactions are recorded as necessary for preparation of our financial statements; providing reasonable assurance that receipts and expenditures of Company assets are made in accordance with management authorization; and providing reasonable assurance that unauthorized acquisition, use, or disposition of Company assets that could have a material effect on our financial statements would be prevented or detected on a timely basis. Because of its inherent limitations, internal control over financial reporting is not intended to provide absolute assurance that a misstatement of our financial statements would be prevented or detected.

Management conducted an evaluation of the effectiveness of the Company’s internal control over financial reporting based on the framework in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this evaluation, management concluded that the Company’s internal control over financial reporting was effective as of December 31, 2016.

Our internal control over financial reporting as of December 31, 2016 has been audited by KPMG LLP, an independent registered public accounting firm, as stated in their report which is included herein.

Under the supervision and with the participation of our management, including our Principal Executive Officer and Principal Financial Officer, we conducted an evaluation of any changes in our internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during our most recently completed fiscal quarter. Based on that evaluation, our Principal Executive Officer and Principal Financial Officer concluded that there has not been any change in our internal control over financial reporting during that quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

The information required to be disclosed by this item is incorporated herein by reference to our definitive proxy statement for the 2017 Annual Meeting of Stockholders (the “2017 Proxy Statement”), which we expect to file with the SEC within 120 days after the end of our fiscal year ended December 31, 2016.

The information required to be disclosed by this item is incorporated herein by reference to the 2017 Proxy Statement, which we expect to file with the SEC within 120 days after the end of our fiscal year ended December 31, 2016.

A description of our equity compensation plans approved by our shareholders is included in Note 9 to the accompanying consolidated financial statements.

On December 30, 2016, the closing price of Mobile Mini’s common stock as reported by The NASDAQ Stock Market was $30.25.

All other information required to be disclosed by this item is incorporated herein by reference to the 2017 Proxy Statement, which we expect to file with the SEC within 120 days after the end of our fiscal year ended December 31, 2015.
