PART I

ITEM 1.

BUSINESS.

General Overview

McGrath RentCorp is a California corporation organized in 1979 with corporate offices located in Livermore, California. The Company’s common stock is traded on the NASDAQ Global Select Market under the symbol “MGRC”. References in this report to the “Company”, “we”, “us”, and “ours” refer to McGrath RentCorp and its subsidiaries, unless the context requires otherwise.

The Company is a diversified business to business rental company with three rental divisions: relocatable modular buildings, electronic test equipment, and liquid and solid containment tanks and boxes. Although the Company’s primary emphasis is on equipment rentals, sales of equipment occur in the normal course of business. The Company is comprised of four business segments: (1) Mobile Modular Management Corporation (“Mobile Modular”), which includes our modular building rental division and our portable storage business (“Mobile Modular Portable Storage”); (2) our electronic test equipment rental division (‘TRS-RenTelco”), which also includes our environmental test equipment rental business (“TRS-Environmental”); (3) Adler Tank Rentals, LLC, our wholly-owned subsidiary providing containment solutions for the storage of hazardous and non-hazardous liquids and solids (“Adler Tanks”); and (4) Enviroplex, Inc., our wholly-owned subsidiary classroom manufacturing business selling modular buildings used primarily as classrooms in California (“Enviroplex”). Mobile Modular Portable Storage and TRS-Environmental each represent less than 2% of the Company’s 2011 total revenues.

No single customer has accounted for more than 10% of the Company’s total revenues generated in any given year. In addition, total foreign country customers and operations accounted for less than 10% of the Company’s revenues and long-lived assets in all years presented.

-1-

Business Model

The Company invests capital in rental products and generally has recovered its original investment through rents less operating expenses in a relatively short period of time compared to the product’s rental life. When the Company’s rental products are sold, the proceeds generally have covered a high percentage of the original investment. With these characteristics, a significant base of rental assets on rent generate a considerable amount of operating cash flows to support continued rental asset growth. The Company’s rental products have the following characteristics:

•

The product required by the customer tends to be expensive compared to the Company’s monthly rental charge, with the interim rental solution typically evaluated as a less costly alternative.

•

Generally, we believe the Company’s customers have a short-term need for our rental products. The customer’s rental requirement may be driven by a number of factors including time, budget or capital constraints, future uncertainty impacting their ongoing requirements, equipment availability, specific project requirements, peak periods of demand or the customer may want to eliminate the burdens and risks of ownership. For modulars, in some cases a customer’s initial short-term rental becomes part of the customer’s ongoing infrastructure and turns into a long-term rental.

•

All of the Company’s rental products have long useful lives relative to the typical rental term. Modulars have an estimated life of eighteen years compared to the typical rental term of twelve to twenty-four months, electronic test equipment has an estimated life range of one to eight years (depending on the type of product) compared to a typical rental term of one to six months, and liquid and solid containment tanks and boxes have an estimated life of twenty years compared to typical rental terms of one to six months.

•

We believe short-term rental rates typically recover the Company’s original investment quickly based on the respective product’s annual yield, or annual rental revenues divided by the average cost of rental inventory. For modulars the original investment is recovered in approximately six years, and in approximately three years for both electronic test equipment and liquid and solid containment tanks and boxes.

•

When a product is sold from our rental inventory, a significant portion of the original investment is usually recovered. Effective asset management is a critical element to each of the rental businesses and the residuals realized when product is sold from inventory. Modular asset management requires designing and building the product for a long life, coupled with ongoing repair and maintenance investments, to ensure its long useful rental life and generally higher residuals upon sale. Electronic test equipment asset management requires understanding, selecting and investing in equipment technologies that support market demand and, once invested, proactively managing the equipment at the model level for optimum utilization through its technology life cycle to maximize the rental revenues and residuals realized. Liquid and solid containment tanks and boxes asset management requires selecting and purchasing quality product and making ongoing repair and maintenance investments to ensure its long rental life.

The Company believes that rental revenue growth from an increasing base of rental assets and improved gross profits on rents are the best measures of the health of each of our rental businesses. Additionally, we believe our business model and results are enhanced with operational leverage that is created from large regional sales and inventory centers for modulars, a single U.S. based sales, inventory and operations facility for electronic test equipment, as well as shared senior management and back office functions for financing, human resources, insurance, and operating and accounting systems.

Employees

As of December 31, 2011, the Company had 742 employees, of whom 66 were primarily administrative and executive personnel, with 378, 153, 84 and 61 in the operations of Mobile Modular, TRS-RenTelco, Adler Tanks and Enviroplex, respectively. None of our employees are covered by a collective bargaining agreement, and management believes its relationship with our employees is good.

RELOCATABLE MODULAR BUILDINGS

Description

Modulars are designed for use as classrooms, temporary offices adjacent to existing facilities, sales offices, construction field offices, restroom buildings, health care clinics, child care facilities, office space, and for a variety of other purposes and may be moved from one location to another. Modulars vary from simple single-unit construction site offices to multi-floor modular complexes. The Company’s modular rental fleet includes a full range of styles and sizes. The Company considers its modulars to be among the most attractive and well designed available. The units are constructed with wood or metal siding, sturdily built and physically capable of a long useful life. Units are generally provided with installed heat, air conditioning, lighting, electrical outlets and floor covering, and may have customized interiors including partitioning, cabinetry and plumbing facilities.

Mobile Modular purchases new modulars from various manufacturers who build to Mobile Modular’s design specifications. With the exception of Enviroplex, none of our principal suppliers are affiliated with the Company. During 2011, Mobile Modular purchased 29% of its modular units from one manufacturer. The Company believes that the loss of any of its primary modular manufacturers could have an adverse effect on its operations since Mobile Modular could experience higher prices and longer lead times for delivery of modular units until other manufacturers were able to increase their production capacity.

The Company’s modulars are manufactured to comply with state building codes, have a low risk of obsolescence, and can be modified or reconfigured to accommodate a wide variety of customer needs. Historically, as state building codes have changed over the years, Mobile Modular has been able to continue to use existing modulars, with minimal, if any, required upgrades. The Company has no assurance that it will continue to be able to use existing modular equipment with minimal upgrades as building codes change in the future.

Mobile Modular currently operates from two regional sales and inventory centers in California, one in Texas, and one in Florida, serving large geographic areas in these states, and sales offices serving North Carolina, Georgia, Maryland, Virginia and Washington, D.C. The California, Texas and Florida regional sales and inventory centers have in-house infrastructure and operational capabilities to support quick and efficient repair, modification, and refurbishment of equipment for the next rental opportunity. The Company believes operating from large regional sales and inventory centers results in better operating margins as operating costs can be spread over a large installed customer base. Mobile Modular actively maintains and repairs its rental equipment, and management believes this ensures the continued use of the modular product over its long life and, when sold, has resulted in higher sale proceeds relative to its capitalized cost. When rental equipment returns from a customer, the necessary repairs and preventative maintenance are performed prior to its next rental. By making these expenditures for repair and maintenance throughout the equipment’s life we believe that older equipment can generally rent for similar rates as newer equipment. Management believes the condition of the equipment is a more significant factor in determining the rental rate and sale price than its age. Over the last three years, used equipment sold each year represented less than 2% of rental equipment, and has been, on average, 12 years old with sale proceeds above its net book value.

Competitive Strengths

Market Leadership—The Company believes Mobile Modular is the largest supplier in California, and a significant supplier in Florida and Texas, of modular educational facilities for rental to both public and private schools. Management is knowledgeable about the needs of its educational customers and the related regulatory requirements in the states where Mobile Modular operates, which enables Mobile Modular to meet its customers’ specific project requirements.

Expertise—The Company believes that over the more than 30 years during which Mobile Modular has competed in the modular rental industry, it has developed expertise that differentiates it from its competitors. Mobile Modular has dedicated its attention to continuously developing and improving the quality of its modular units. Mobile Modular has expertise in the licensing and regulatory requirements that govern modulars in the states where it operates, and its management, sales and operational staffs are knowledgeable and committed to providing exemplary customer service. Mobile Modular has expertise in project management and complex applications.

-4-

Operating Structure—Part of the Company’s strategy for Mobile Modular is to create facilities and infrastructure capabilities that its competitors cannot easily duplicate. Mobile Modular achieves this by building regional sales and inventory centers designed to serve a broad geographic area and a large installed customer base under a single overhead structure, thereby reducing its cost per transaction. The Company’s regional facilities and related infrastructure enable Mobile Modular to maximize its modular inventory utilization through efficient and cost effective in-house repair, maintenance and refurbishment for quick redeployment of equipment to meet its customers’ needs.

Asset Management—The Company believes Mobile Modular markets high quality, well-constructed and attractive modulars. Mobile Modular requires manufacturers to build to its specifications, which enables Mobile Modular to maintain a standardized quality fleet. In addition, through its ongoing repair, refurbishment and maintenance programs, the Company believes Mobile Modular’s buildings are the best maintained in the industry. The Company depreciates its modular buildings over an 18 year estimated useful life to a 50% residual value. Older buildings continue to be productive primarily because of Mobile Modular’s focus on ongoing fleet maintenance. Also, as a result of Mobile Modular’s maintenance programs, when a modular unit is sold, a high percentage of the equipment’s capitalized cost is recovered. In addition, the fleet’s utilization is regionally optimized by managing inventory through estimates of market demand, fulfillment of current rental and sale order activity, modular returns and capital purchases.

Customer Service—The Company believes the modular rental industry to be service intensive and locally based. The Company strives to provide excellent service by meeting its commitments to its customers, being proactive in resolving project issues and seeking to continuously improve the customers’ experience. Mobile Modular is committed to offering quick response to requests for information, providing experienced assistance, on time delivery and preventative maintenance of its units. Mobile Modular’s goal is to continuously improve its procedures, processes and computer systems to enhance internal operational efficiency. The Company believes this dedication to customer service results in high levels of customer loyalty and repeat business.

Market

Management estimates renting relocatable modular buildings is an industry that today has equipment on rent or available for rent in the U.S. with an aggregate original cost of over $4.0 billion. Mobile Modular’s largest market segment is for temporary classroom and other educational space needs of public and private schools, colleges and universities in California and Florida, and to a lesser extent in Texas, North Carolina, Georgia, Maryland, Virginia and Washington, D.C. Management believes the demand for rental classrooms is caused by shifting and fluctuating school populations, the lack of state funds for new construction, the need for temporary classroom space during reconstruction of older schools, class size reduction and the phasing out of portable classrooms compliant with older building codes (see “Classroom Rentals and Sales to Public Schools (K-12)” below). Other customer applications include sales offices, construction field offices, health care facilities, church sanctuaries and child care services. Industrial, manufacturing, entertainment and utility companies, as well as governmental agencies commonly use large multi-modular complexes to serve their interim administrative and operational space needs. Modulars offer customers quick, cost-effective space solutions while conserving their capital. The Company’s corporate offices, and California, Texas and Florida regional sales and inventory center offices are housed in various sizes of modular units.

Since most of Mobile Modular’s customer requirements are to fill temporary space needs, Mobile Modular’s marketing emphasis is on rentals rather than sales. Mobile Modular attracts customers through its website at www.mobilemodularrents.com, internet advertising and direct mail. Customers are encouraged to visit a regional sales and inventory center to view different models on display and to see a regional office, which is a working example of a modular application.

Because service is a major competitive factor in the rental of modulars, Mobile Modular offers quick response to requests for information, assistance in the choice of a suitable size and floor plan, in-house customization services, rapid delivery, timely installation and field service of its units. On Mobile Modular’s website, customers are able to view and select inventory for quotation and request in-field service.

Rentals

Rental periods range from one month to several years with a typical initial contract term between twelve and twenty-four months. In general, monthly rental rates are determined by a number of factors including length of term, market demand, product availability

-5-

and product type. Upon expiration of the initial term, or any extensions, rental rates are reviewed, and when appropriate, are adjusted based on current market conditions. Most rental agreements are operating leases that provide no purchase options, and when a rental agreement does provide the customer with a purchase option, it is generally on terms management believes to be attractive to Mobile Modular.

The customer is responsible for obtaining the necessary use permits and the costs of insuring the unit, transporting the unit to the site, preparation of the site, installation of the unit, dismantle and return delivery of the unit to Mobile Modular, and certain costs for customization. Mobile Modular maintains the units in good working condition while on rent. Upon return, the units are inspected for damage and customers are billed for items considered beyond normal wear and tear. Generally, the units are then repaired for subsequent use. Repair and maintenance costs are expensed as incurred and can include floor repairs, roof maintenance, cleaning, painting and other cosmetic repairs. The costs of major refurbishment of equipment are capitalized to the extent the refurbishment significantly improves the quality and adds value or life to the equipment.

At December 31, 2011, Mobile Modular owned 35,639 new or previously rented modulars and portable storage containers with an aggregate cost of $539.1 million including accessories, or an average cost per unit of $15,100. Utilization is calculated each month by dividing the cost of rental equipment on rent by the total cost of rental equipment, excluding new equipment inventory and accessory equipment. At December 31, 2011, fleet utilization was 67.3% and average fleet utilization during 2011 was 67.1%. The Mobile Modular segment includes the results of operations of Mobile Modular Portable Storage, which represented less than 2% of the Company’s 2011 total revenues.

Sales

In addition to operating its rental fleet, Mobile Modular sells modulars to customers. These sales typically arise out of its marketing efforts for the rental fleet and from existing equipment already on rent. Such sales can be of either new or used units from the rental fleet, which permits turnover of older units. During 2011 Mobile Modular’s largest sale represented approximately 14% of Mobile Modular’s sales, 4% of the Company’s consolidated sales and less than 1% of the Company’s consolidated revenues.

Mobile Modular typically provides limited 90-day warranties on used modulars and passes through the manufacturers’ one-year warranty on new units to its customers. Warranty costs have not been significant to Mobile Modular’s operations to date, and the Company attributes this to its commitment to high quality standards and regular maintenance programs. However, there can be no assurance that warranty costs will continue to be insignificant to Mobile Modular’s operations in the future.

Enviroplex manufactures portable classrooms built to the requirements of the California Division of the State Architect (“DSA”) and sells directly to California public school districts and other educational institutions.

Seasonality

Typically, during each calendar year, our highest numbers of classrooms are shipped for rental and sale orders during the second and third quarters for delivery and installation prior to the start of the upcoming school year. The majority of classrooms shipped in the second and third quarters have rental start dates during the third quarter, thereby making the fourth quarter the first full quarter of rental revenues recognized for these transactions.

Competition

Competition in the rental and sale of relocatable modular buildings is intense. Two major national firms, Williams Scotsman International, Inc. and Modspace, Inc., are engaged in the rental of modulars, have many offices throughout the country and we believe may have greater financial resources than Mobile Modular. In addition, a number of other smaller companies operate regionally throughout the country. Mobile Modular operates primarily in California, Texas, Florida, North Carolina, Georgia, Virginia, Maryland and Washington, D.C. Significant competitive factors in the rental business include availability, price, service, reliability, appearance and functionality of the product. Mobile Modular markets high quality, well-constructed and attractive modulars. Part of the Company’s strategy for modulars is to create facilities and infrastructure capabilities that its competitors cannot easily duplicate. The Company’s facilities and related infrastructure enable it to modify modulars efficiently and cost effectively to meet its customers’ needs. Management’s goal is to be more responsive at less expense. Management believes this strategy, together with its emphasis on prompt and efficient customer service, gives Mobile Modular a competitive advantage. Mobile Modular is

-6-

determined to respond quickly to requests for information, and provide experienced assistance for the first-time user, rapid delivery and timely repair of its modular units. Mobile Modular’s already high level of efficiency and responsiveness continues to improve as the Company upgrades procedures, processes and computer systems that control its internal operations. The Company anticipates intense competition to continue and believes it must continue to improve its products and services to remain competitive in the market for modulars.

Classroom Rentals and Sales to Public Schools (K-12)

Mobile Modular and Enviroplex provide classroom and specialty space needs serving public and private schools, colleges and universities. Within the educational market, the rental (by Mobile Modular) and sale (by Enviroplex and Mobile Modular) of modulars to public school districts for use as portable classrooms, restroom buildings and administrative offices for kindergarten through grade twelve (K-12) are a significant portion of the Company’s revenues. Mobile Modular rents and sells classrooms in California, Florida, Texas, North Carolina, Georgia, Maryland, Virginia and Washington, D.C. Enviroplex sells classrooms in the California market. California is Mobile Modular’s largest educational market. Historically, demand in this market has been fueled by shifting and fluctuating student populations, insufficient funding for new school construction, class size reduction programs, modernization of aging school facilities and the phasing out of portable classrooms no longer compliant with current building codes. The following table shows the approximate percentages of the Company’s modular rental and sales revenues, and of its consolidated rental and sales revenues for the past five years, that rentals and sales to these schools constitute:


Rentals and Sales to Public Schools (K-12) as a Percentage of Total Rental and Sales Revenues
Percentage of:	2011			2010			2009			2008			2007
Modular Rental Revenues (Mobile Modular)		44	%		48	%		51	%		51	%		50	%
Modular Sales Revenues (Mobile Modular & Enviroplex)		33	%		54	%		64	%		60	%		59	%
Modular Rental and Sales Revenues (Mobile Modular & Enviroplex)		40	%		49	%		54	%		54	%		53	%
Consolidated Rental and Sales Revenues¹		16	%		22	%		28	%		30	%		30	%
1. Consolidated Rental and Sales Revenue percentage is calculated by dividing Modular rental and sales revenues to public schools (K-12) by the Company’s consolidated rental and sales revenues.

School Facility Funding

Funding for public school facilities is derived from a variety of sources including the passage of both statewide and local facility bond measures, operating budgets, developer fees, various taxes including parcel and sales taxes levied to support school operating budgets, and lottery funds. The Company has experienced interruption in the passage of facility bonds, contraction or elimination of class size reduction programs, a lack of fiscal funding, and a significant reduction of funding from other sources to public schools that has had a material adverse effect on both rental and sales revenues of the Company.

ELECTRONIC TEST EQUIPMENT

Description

TRS-RenTelco rents and sells electronic test equipment nationally and internationally from two facilities located in Grapevine, Texas (the Dallas facility) and Dollard-des-Ormeaux, Canada (the Montreal facility). TRS-RenTelco’s revenues are derived from the rental and sale of general purpose, communications and environmental test equipment to a broad range of companies, from Fortune 500 to middle and smaller market companies, in the aerospace, defense, communications, manufacturing and semiconductor industries. Electronic test equipment revenues are primarily affected by the business activity within these industries related to research and development, manufacturing, and communication infrastructure installation and maintenance. The Dallas facility houses the electronic test equipment inventory, sales engineers, calibration laboratories, and operations staff for U.S. and international business. The Montreal facility houses sales engineers and operations staff to serve the Canadian market. As of December 31, 2011, the original cost of electronic test equipment inventory was comprised of 63% general-purpose electronic test equipment, 34% communications electronic test equipment and 3% environmental test equipment.

Engineers, technicians and scientists utilize general purpose electronic test equipment in developing products, controlling manufacturing processes, completing field service applications and evaluating the performance of their own electrical and electronic equipment. These instruments are rented primarily to aerospace, defense, electronics, industrial, research and semiconductor industries. To date, Agilent Technologies and Tektronix, a division of Danaher Corporation, have manufactured the majority of TRS-RenTelco’s general purpose electronic test equipment.

Communications test equipment, including fiber optic test equipment, is utilized by technicians, engineers and installation contractors to evaluate voice, data and multimedia communications networks, to install fiber optic cabling, and in the development and manufacturing of transmission, network and wireless products. These instruments are rented primarily to manufacturers of communications equipment and products, electrical and communications installation contractors, field technicians, and service providers. To date, Agilent has manufactured a significant portion of TRS-RenTelco’s communications test equipment, with the remainder acquired from over 50 other manufacturers.

TRS-RenTelco’s general purpose test equipment rental inventory includes oscilloscopes, amplifiers, analyzers (spectrum, network and logic), signal source and power source test equipment. The communications test equipment rental inventory includes network and transmission test equipment for various fiber, copper and wireless networks. Agilent Technologies and Tektronix manufacture the majority of the general purpose inventory and the communications test equipment inventory includes equipment from over 50 different manufacturers. TRS-RenTelco also occasionally rents electronic test equipment from other rental companies and re-rents the equipment to customers.

Competitive Strengths

Market Leadership—The Company believes that TRS-RenTelco is one of the largest electronic test equipment rental and leasing companies offering a broad and deep selection of general purpose and communications test equipment for rent in North America.

Expertise—The Company believes that its knowledge of products, technology and applications expertise provides it with a competitive advantage over others in the industry. Customer requirements are supported by application engineers and technicians that are knowledgeable about the equipment’s uses to ensure the right equipment is selected to meet the customer’s needs. This knowledge can be attributed to the experience of TRS-RenTelco’s management, sales and operational teams.

Operating Structure—TRS-RenTelco is supported by a centralized distribution and inventory center on the grounds of the Dallas-Fort Worth Airport in Texas. The Company believes that the centralization of servicing all customers in North America and internationally by TRS-RenTelco’s experienced logistics teams provides a competitive advantage by minimizing transaction costs and enabling TRS-RenTelco to ensure customer requirements are met.

Asset Management—TRS-RenTelco’s rental equipment inventory is serviced by an ISO 9001-2008 registered and compliant calibration laboratory that repairs and calibrates equipment ensuring that off rent equipment is ready to ship immediately to meet customers’ needs. TRS-RenTelco’s team of technicians, product managers and sales personnel are continuously monitoring and analyzing the utilization of existing products, new technologies, general economic conditions and estimates of customer demand to

-8-

ensure the right equipment is purchased and sold, at the right point in the equipment’s technology life cycle. The Company believes this enables it to maximize utilization of equipment and the cash flow generated by the rental and sales revenue of each model of equipment. TRS-RenTelco strives to maintain strong relationships with equipment manufacturers, which enables it to leverage those relationships to gain rental opportunities.

Customer Service—The Company believes that its focus on providing excellent service to its customers provides a competitive advantage. TRS-RenTelco strives to provide exemplary service to fulfill its commitments to its customers. TRS-RenTelco prides itself in providing solutions to meet customers’ needs by having equipment available, and responding quickly and thoroughly to their requests. TRS-RenTelco’s sophisticated in-house laboratory ensures the equipment is fully functional and meets its customers’ delivery requirements. Service needs of TRS-RenTelco’s customers are supported 24 hours a day, 7 days a week by its customer care specialists. TRS-RenTelco’s goal is to provide service beyond its customers’ expectations, which, the Company believes, results in customer loyalty and repeat business.

Market

Renting electronic test equipment is a market which we estimate has equipment on rent worldwide or available for rent with an aggregate original cost in excess of $1 billion. There is a broad customer base for the rental of such instruments, including aerospace, communications, defense, electrical contractor, electronics, industrial, installer contractor, network systems, research and environmental companies.

TRS-RenTelco markets its electronic test equipment throughout the United States, Canada, and, to a limited extent, other countries. TRS-RenTelco attracts customers through its outside sales force, website at www.TRS-RenTelco.com, telemarketing program, trade show participation and electronic mail campaigns. A key part of the sales process is TRS-RenTelco’s knowledgeable inside sales engineering team that effectively matches test equipment solutions to meet specific customer’s requirements.

The Company believes that customers rent electronic test equipment for many reasons. Customers frequently need equipment for short-term projects, to evaluate new products, and for backup to avoid costly downtime. Delivery times for the purchase of such equipment can be lengthy; thus, renting allows the customer to obtain the equipment expeditiously. The Company also believes that the relative certainty of rental costs can facilitate cost control and be useful in the bidding of and pass-through of contract costs. Finally, renting rather than purchasing may better satisfy the customer’s budgetary constraints.

Rentals

TRS-RenTelco rents electronic test equipment typically for rental periods of one to six months, although in some instances, rental terms can be up to a year or longer. Monthly rental rates typically are between 2% and 10% of the current manufacturers’ list price. TRS-RenTelco depreciates its equipment over 1 to 8 years with no residual value.

At December 31, 2011, TRS-RenTelco had an electronic test equipment rental inventory including accessories with an aggregate cost of $258.6 million. Utilization is calculated each month by dividing the cost of the rental equipment on rent by the total cost of rental equipment, excluding accessory equipment. Utilization was 67.1% as of December 31, 2011 and averaged 66.0% during the year. The TRS-RenTelco segment includes the results of operations of TRS-Environmental, which represented less than 2% of the Company’s 2011 total revenues.

Sales

TRS-RenTelco generally sells used equipment to maintain an inventory of equipment meeting more current technological standards, and to support maintaining target utilization levels at a model number level. In 2011, approximately 20% of the electronic test equipment revenues were derived from sales. The largest electronic test equipment sale during 2011 represented approximately 4.0% of electronic test equipment sales, 1.5% of the Company’s consolidated sales and 0.3% of consolidated revenues.

Seasonality

Rental activity may decline in the fourth quarter month of December and the first quarter months of January and February. These months may have lower rental activity due to holiday closures, particularly by larger companies, inclement weather and its impact on

various field related communications equipment rentals, and companies’ operational recovery from holiday closures which may impact the start-up of new projects coming online in the first quarter. These factors may impact the quarterly results of each year’s first and fourth quarter.

LIQUID AND SOLID CONTAINMENT TANKS AND BOXES

Description

Adler Tanks’ rental inventory is comprised of tanks and boxes used for various containment solutions to store hazardous and non-hazardous liquids and solids in applications such as: oil and gas exploration and field services, refinery, chemical and industrial plant maintenance, environmental remediation and field services, infrastructure building construction, marine services, pipeline construction and maintenance, tank terminals services, wastewater treatment, and waste management and landfill services. The tanks and boxes are comprised of the following products:

•

fixed axle steel tanks (“tanks”) for the storage of groundwater, wastewater, volatile organic liquids, sewage, slurry and bio sludge, oil and water mixtures and chemicals, which are available in a variety of sizes including 21,000 gallon, 16,000 gallon and 8,000 gallon sizes;

•

vacuum containers (“boxes”), which provide secure containment of sludge and solid materials and may be used for additional on-site storage or for transporting materials off-site enabling vacuum trucks to remain in operation;

•

dewatering boxes for the separation of water contained in sludge and slurry; and

•

roll-off and trash boxes for the temporary storage and transport of solid waste.

Adler Tanks purchases tanks and boxes from various manufacturers located throughout the country. With the exception of Sabre Manufacturing LLC (“Sabre”), none of the principal suppliers are affiliated with the Company. Sabre is independently operated and is 100% owned by the President of Adler Tanks. Adler Tanks purchases tanks from Sabre on terms and conditions pursuant to arms-length negotiations conducted at the time of purchase.

Competitive Strengths

Market Leadership—The Company believes that Adler Tanks is one of the largest participants in the liquid and solid containment tanks and boxes rental business in North America. Adler Tanks has national reach from branches serving the Northeast, Mid-Atlantic, Midwest, Southeast, Southwest and West.

Expertise and Customer Service—The Company believes that Adler Tanks has highly experienced operating management and branch employees. Adler Tanks employees are knowledgeable about the operation of its rental equipment and customer applications. Adler Tanks believes that it provides a superior level of customer service due to its strong relationship building skills and the quality of its responsiveness.

Asset Management—The Company believes that Adler Tanks markets a high quality, well constructed and well maintained rental product. The Company depreciates its tanks and boxes over a 20 year estimated useful life to 0% residual value. We believe that if maintained, older tanks and boxes will continue to produce similar rental rates as newer equipment. The fleet’s utilization is regionally optimized by understanding customer demand, expected returns and manufacturer’s production capacity.

Market

Renting liquid and solid containment equipment in the U.S. is a market which we estimate has $1.4 billion of annual rental revenues. There are a large and diverse number of market segments including oil and gas exploration and field services, refinery, chemical and industrial plant maintenance, environmental remediation and field services, infrastructure building construction, marine services, pipeline construction and maintenance, tank terminals services, wastewater treatment, and waste management and landfill services.

The tank and box rental products that Adler Tanks builds may be utilized throughout the U.S. and are not subject to any local or regional construction code or approval standards.

Rentals

Adler Tanks rents tanks and boxes typically for rental periods of one to six months, although in some instances, rental terms can be up to a year or longer. Monthly rental rates typically are between 2% and 10% of the equipment’s original acquisition cost. Utilization is calculated each month by dividing the cost of the rental equipment on rent by the total cost of rental equipment, excluding accessory equipment. Utilization was 79.8% at December 31, 2011 and averaged 86.2% during the year.

-11-

Seasonality

Rental activity may decline in the fourth quarter month of December and the first quarter months of January and February. These months may have lower rental activity due to inclement weather in certain regions of the country impacting the industries that we serve.

Competition

The liquid and solid containment rental industry is highly competitive including national, regional and local companies. Some of our national competitors, notably BakerCorp and Rain For Rent, are significantly larger than we are and may have greater financial and marketing resources than we have. Some of our competitors also have longer operating histories, lower cost basis of rental equipment, lower cost structures and more established relationships with equipment manufacturers than we have. In addition, certain of our competitors are more geographically diverse than we are and have greater name recognition among customers than we do. As a result, our competitors that have these advantages may be better able to attract customers and provide their products and services at lower rental rates. Adler Tanks competes with these companies based upon product availability, product quality, price, service and reliability. We may encounter increased competition in the markets that we serve from existing competitors or from new market entrants in the future.

ITEM 1A. RISK FACTORS

You should carefully consider the following discussion of various risks and uncertainties. We believe these risk factors are the most relevant to our business and could cause our results to differ materially from the forward-looking statements made by us. Our business, financial condition, and results of operations could be seriously harmed if any of these risks or uncertainties actually occur or materialize. In that event, the market price for our common stock could decline, and you may lose all or part of your investment.

The effects of a recession and tightened credit markets in the U.S. and other countries may adversely impact our business and financial condition and may negatively impact our ability to access financing.

Demand for our rental products depends on continued industrial and business activity and state government funding. The effects of a U.S. recession and general global economic downturn may adversely affect our customers, including local school districts that are subject to budgetary constraints, which could result in decreased demand for the products we rent. Reduced demand for our rental products and deflation could increase price competition. This lowered demand and price pressure could have a material adverse effect on our revenue and profitability. In 2011 we experienced decreased demand and lower pricing in our California modular operations.

The recent instability in the global financial system may also have an impact on our business and our financial condition. General economic conditions and the tightening credit markets have significantly affected the ability of many companies to raise new capital or refinance existing indebtedness. While we intend to finance expansion with cash flow from operations and borrowing under our existing unsecured revolving line of credit facility, we may require additional financing to support our continued growth. Due to constriction in the capital markets, should we need to access the market for additional funds or to refinance our existing indebtedness, we may not be able to obtain such additional funds on terms acceptable to the Company or at all. All of these factors could impact our business, resulting in lower revenues and lower levels of earnings in future periods. At the current time we are uncertain as to the magnitude, or duration, of such changes in our business.

Our stock price has fluctuated and may continue to fluctuate in the future, which may result in a decline in the value of your investment in our common stock.

The market price of our common stock fluctuates on the NASDAQ Global Select Market and is likely to be affected by a number of factors including but not limited to:

•

our operating performance and the performance of our competitors, and in particular any variations in our operating results or dividend rate from our stated guidance or from investors’ expectations;

•

any changes in general conditions in the economy, the industries in which we operate or the financial markets;

•

investor’s reaction to our press releases, public announcements or filings with the SEC;

•

the stock price performance of competitors or other comparable companies;

•

any changes in research analysts’ coverage, recommendations or earnings estimates for us or for the stocks of other companies in our industry;

•

any sales of common stock by our directors, executive officers and our other large shareholders, particularly in light of the limited trading volume of our stock;

•

any merger and acquisition activity that involves us or our competitors; and

•

other announcements or developments affecting us, our industry, customers, suppliers or competitors.

In addition, in recent years the stock market has experienced significant price and volume fluctuations. These fluctuations are often unrelated to the operating performance of particular companies. More recently, the global credit crisis adversely affected the prices of publicly traded stocks across the board as many stockholders have become more willing to divest their stock holdings at lower values to increase their cash flow and reduce exposure. These broad market fluctuations and any negative economic trends may cause declines in the market price of our common stock and may be based upon factors that have little or nothing to do with our Company or its performance, and these fluctuations and trends could materially reduce our stock price.

-15-

Our future operating results may fluctuate, fail to match past performance or fail to meet expectations.

Our operating results may fluctuate in the future, may fail to match our past performance or fail to meet the expectations of analysts and investors. Our results and related ratios, such as gross margin, operating income percentage and effective tax rate may fluctuate as a result of a number of factors, some of which are beyond our control including but not limited to:

•

general economic conditions in the geographies and industries where we rent and sell our products;

•

legislative and educational policies where we rent and sell our products;

•

the budgetary constraints of our customers;

•

seasonality of our rental businesses and our end-markets;

•

success of our strategic growth initiatives;

•

costs associated with the launching or integration of new or acquired businesses;

•

the timing and type of equipment purchases, rentals and sales;

•

the nature and duration of the equipment needs of our customers;

•

the timing of new product introductions by us, our suppliers and our competitors;

•

the volume, timing and mix of maintenance and repair work on our rental equipment;

•

our equipment mix, availability, utilization and pricing;

•

the mix, by state and country, of our revenues, personnel and assets;

•

rental equipment impairment from excess, obsolete or damaged equipment;

•

movements in interest rates or tax rates;

•

changes in, and application of, accounting rules;

•

changes in the regulations applicable to us; and

•

litigation matters.

As a result of these factors, our historical financial results are not necessarily indicative of our future results.

Our ability to retain our executive management and to recruit, retain and motivate key employees is critical to the success of our business.

If we cannot successfully recruit and retain qualified personnel, our operating results and stock price may suffer. We believe that our success is directly linked to the competent people in our organization, including our executive officers, senior managers and other key personnel, and in particular, Dennis Kakures, our Chief Executive Officer. Personnel turnover can be costly and could materially and adversely impact our operating results and can potentially jeopardize the success of our current strategic initiatives. We need to attract and retain highly qualified personnel to replace personnel when turnover occurs, as well as add to our staff levels as growth occurs. Our business and stock price likely will suffer if we are unable to fill, or experience delays in filling open positions, or fail to retain key personnel when turnover occurs.

Failure by third parties to manufacture and deliver our products to our specifications or on a timely basis may harm our reputation and financial condition.

We depend on third parties to manufacture our products even though we are able to purchase products from a variety of third-party suppliers. In the future, we may be limited as to the number of third-party suppliers for some of our products. Although in general we make advance purchases of some products to help ensure an adequate supply, currently we do not have any long-term purchase contracts with any third-party supplier. We may experience supply problems as a result of financial or operating difficulties or failure of our suppliers. We may also experience supply problems as a result of shortages, and discontinuations resulting from product obsolescence or other shortages or allocations by suppliers. Unfavorable economic conditions may also adversely affect our suppliers or the terms on which we purchase products. In the future, we may not be able to negotiate arrangements with third parties

-16-

to secure products that we require in sufficient quantities or on reasonable terms. If we cannot negotiate arrangements with third parties to produce our products or if the third parties fail to produce our products to our specifications or in a timely manner, our reputation and financial condition could be harmed.

Disruptions in our information technology systems could limit our ability to effectively monitor and control our operations and adversely affect our operations.

Our information technology systems facilitate our ability to monitor and control our operations and adjust to changing market conditions. Any disruption in our information technology systems or the failure of these systems to operate as expected could, depending on the magnitude of the problem, adversely affect our operating results by limiting our capacity to effectively transact business, monitor and control our operations and adjust to changing market conditions in a timely manner.

The delay or failure to implement information system upgrades and new systems effectively could disrupt our business, distract management’s focus and attention from our business operations and growth initiatives, and increase our implementation and operating costs, any of which could negatively impact our operations and operating results.

We have engaged in acquisitions and may engage in future acquisitions that could negatively impact our results of operations, financial condition and business.

In 2004, we acquired TRS, an electronic test equipment rental business and in 2008 we acquired Adler Tanks, a liquid and solid containment rental business. We anticipate that we will continue to consider acquisitions in the future that meet our strategic growth plans. We are unable to predict whether or when any prospective acquisition will be completed. Acquisitions involve numerous risks, including the following:

•

difficulties in integrating the operations, technologies, products and personnel of the acquired companies;

•

diversion of management’s attention from normal daily operations of the business;

•

difficulties in entering markets in which we have no or limited direct prior experience and where competitors in such markets have stronger market positions;

•

difficulties in complying with regulations, such as environmental regulations, and managing risks related to an acquired business;

•

timely completion of necessary financing and required amendments, if any, to existing agreements;

•

an inability to implement uniform standards, controls, procedures and policies;

•

undiscovered and unknown problems, defects, liabilities, or other issues related to any acquisition that become known to us only after the acquisition;

•

negative reactions from our customers to an acquisition;

•

disruptions among employees which may erode employee morale; and

•

potential loss of key employees, including costly litigation resulting from the termination of those employees.

In connection with acquisitions we may;

•

assume liabilities or acquire damaged assets, some of which may be unknown at the time of such acquisitions;

•

record goodwill and non-amortizable intangible assets that will be subject to future impairment testing and potential periodic impairment charges;

•

incur amortization expenses related to certain intangible assets; or

•

become subject to litigation.

Acquisitions are inherently risky, and no assurance can be given that our future acquisitions will be successful or will not adversely affect our business, operating results, or financial condition. Failure to manage and successfully integrate acquisitions we make could harm our business and operating results in a material way. In addition, if we consummate one or more significant future

-17-

acquisitions in which the consideration consists of stock or other securities, our existing shareholders’ ownership could be diluted significantly. If we were to proceed with one or more significant future acquisitions in which the consideration included cash, we could be required to use, to the extent available, a substantial portion of our credit facility. If we increase the amount borrowed against our available credit line, we would increase the risk of breaching the covenants under our credit facilities with our lenders. In addition, it would limit our ability to make other investments, or we may be required to seek additional debt or equity financing.

We could have difficulty integrating businesses that we may acquire, which could adversely affect our results of operations.

The success of our acquisition strategy depends upon our ability to successfully complete acquisitions and integrate any businesses that we acquire into our existing business. The difficulties of integration could be increased by the necessity of coordinating geographically dispersed organizations; maintaining acceptable standards, controls, procedures and policies; integrating personnel with disparate business backgrounds; combining different corporate cultures; and the impairment of relationships with employees and customers as a result of any integration of new management and other personnel. In addition, we could be unable to retain key employees or customers of the combined businesses. We could face integration issues pertaining to the internal controls and operational functions of the acquired companies and we also could fail to realize cost efficiencies or synergies that we anticipated when selecting our acquisition candidates. Any of these items could adversely affect our results of operations.

If we determine that our goodwill and intangible assets have become impaired, we may incur impairment charges, which would negatively impact our operating results.

At December 31, 2011, we had $40.0 million of goodwill and intangible assets, net on our consolidated balance sheets. Goodwill represents the excess of cost over the fair value of net assets acquired in business combinations. We assess potential impairment of our goodwill and intangible assets at least annually. Impairment may result from significant changes in the manner of use of the acquired asset, negative industry or economic trends and significant underperformance relative to historic or projected operating results.

If we do not effectively manage our credit risk, collect on our accounts receivable or recover our rental equipment from our customers’ sites, it could have a material adverse effect on our operating results.

We generally sell to customers on 30-day terms, individually perform credit evaluation procedures on our customers on each transaction and require security deposits or other forms of security from our customers when a significant credit risk is identified. Historically, accounts receivable write-offs and write-offs related to equipment not returned by customers have not been significant and, in each of the last five years have been less than 1% of total revenues. If economic conditions worsen, we may see an increase in bad debt relative to historical levels, which may materially and adversely affect our operations. Failure to manage our credit risk and receive timely payments on our customer accounts receivable may result in the write-off of customer receivables and loss of equipment, particularly electronic test equipment. If we are not able to manage credit risk issues, or if a large number of customers should have financial difficulties at the same time, our credit and equipment losses would increase above historical levels. If this should occur, our results of operations may be materially and adversely affected.

Effective management of our rental assets is vital to our business.

Our modular, electronics and liquid and solid containment rental products have long useful lives and managing those assets is a critical element to each of our rental businesses. Generally, we design units and find manufacturers to build them to our specifications for our modulars and liquid and solid containment tanks and boxes. Modular asset management requires designing and building the product for a long life that anticipates the needs of our customers, including anticipating changes in legislation, regulations, building codes and local permitting in the various markets in which the Company operates. Electronic test equipment asset management requires understanding, selecting and investing in equipment technologies that support market demand, including anticipating technological advances and changes in manufacturers’ selling prices. Liquid and solid containment asset management requires designing and building the product for a long life, using quality components and repairing and maintaining the products to prevent leaks. For each of our modular, electronic test equipment and liquid and solid containment assets, we must successfully maintain and repair this equipment cost-effectively to maximize the useful life of the products and the level of proceeds from the sale of such products.

-18-

The nature of our businesses, including the ownership of industrial property, exposes us to the risk of litigation and liability under environmental, health and safety and products liability laws.

We are subject to national, state, provincial and local environmental laws and regulations concerning, among other things, solid and liquid waste and hazardous substances handling, storage and disposal and employee health and safety. These laws and regulations are complex and frequently change. We could incur unexpected costs, penalties and other civil and criminal liability if we fail to comply with environmental or health and safety laws. We also could incur costs or liabilities related to waste disposal or remediating soil or groundwater contamination at our properties, at our customers’ properties or at third party landfill and disposal sites. These liabilities can be imposed on the parties generating, transporting or disposing of such substances or on the owner or operator of affected property, often without regard to whether the owner or operator knew of, or was responsible for, the presence of hazardous substances.

Several aspects of our businesses involve risks of environmental and health and safety liability. For example, our operations involve the use of petroleum products, solvents and other hazardous substances in the construction and maintaining of modular buildings and for fueling and maintaining our delivery trucks and vehicles. We also own, transport and rent tanks and boxes in which waste materials are placed by our customers. The historical operations at some of our previously owned or leased and newly acquired or leased properties may have resulted in undiscovered soil or groundwater contamination or historical non-compliance. Future events, such as changes in existing laws or policies or their enforcement, or the discovery of currently unknown contamination or non-compliance, may also give rise to liabilities or other claims based on these operations that may be material. In addition, future environmental or health and safety laws and regulations may require significant capital or operational expenditures or changes to our operations.

Accordingly, in addition to potential penalties for non-compliance, we may become liable, either contractually or by operation of law, for investigation, remediation and monitoring costs even if the contaminated property is not presently owned or operated by us, or if the contamination was caused by third parties during or prior to our ownership or operation of the property. In addition, certain parties may be held liable for more than their fair share of environmental investigation and cleanup costs. Contamination and exposure to hazardous substances or other contaminants such as mold can also result in claims for remediation or damages, including personal injury, property damage, and natural resources damage claims. Although expenses related to environmental compliance, health and safety issues, and related matters, have not been material to date, we cannot assure that we will not have to make significant expenditures in the future in order to remain in compliance with applicable laws and regulations. Violations of environmental or health and safety related laws or associated liability could have a material adverse effect on our business, financial condition and results of operations.

In general, litigation in the industries in which we operate, including class actions that seek substantial damages, arises with increasing frequency. Enforcement of environmental and health and safety requirements is also frequent. Such proceedings are invariably expensive, regardless of the merit of the plaintiffs’ or prosecutors’ claims. We may be named as a defendant in the future, and there can be no assurance, irrespective of the merit of such future actions, that we will not be required to make substantial settlement payments in the future. Further, a significant portion of our business is conducted in California which is one of the most highly regulated and litigious states in the country. Therefore, our potential exposure to losses and expenses due to new laws, regulations or litigation may be greater than companies with a less significant California presence.

The nature of our business also subjects us to property damage and product liability claims, especially in connection with our modular buildings and tank and box rental businesses. Although we maintain commercially reasonable liability coverage, an unusually large property damage or product liability claim or a series of claims could exceed our insurance coverage or result in damage to our reputation.

Conducting our routine businesses exposes us to risk of litigation from employees, vendors and other third parties.

We are subject to claims arising from disputes with employees, vendors and other third parties in the normal course of business; these risks may be difficult to assess or quantify and their existence and magnitude may remain unknown for substantial periods of time. If the plaintiffs in any suits against us were to successfully prosecute their claims, or if we were to settle such suits by making significant payments to the plaintiffs, our operating results and financial condition would be harmed. Even if the outcome of a claim

-19-

proves favorable to us, litigation can be time consuming and costly and may divert management resources. In addition, our organizational documents require us to indemnify our senior executives to the maximum extent permitted by California law. If our senior executives were named in any lawsuit, our indemnification obligations could magnify the costs of these suits.

If we suffer loss to our facilities, equipment or distribution system due to catastrophe, our operations could be seriously harmed.

Our facilities, rental equipment and distribution systems may be subject to catastrophic loss due to fire, flood, hurricane, earthquake, terrorism or other natural or man-made disasters. In particular, our headquarters, three operating facilities, and certain of our rental equipment are located in areas of California, with above average seismic activity and could be subject to a catastrophic loss caused by an earthquake. Our rental equipment and facilities in Texas, Florida, North Carolina and Georgia are located in areas subject to hurricanes and other tropical storms. In addition to customers’ insurance on rented equipment, we carry property insurance on our rental equipment in inventory and operating facilities as well as business interruption insurance. We believe our insurance policies are adequate with the appropriate limits and deductibles to mitigate the potential loss exposure of our business. We do not have financial reserves for policy deductibles and we do have exclusions under our insurance policies that are customary for our industry, including earthquakes, flood and terrorism. If any of our facilities or a significant amount or our rental equipment were to experience a catastrophic loss, it could disrupt our operations, delay orders, shipments and revenue recognition and result in expenses to repair or replace the damaged rental equipment and facility not covered by insurance.

Our debt instruments contain covenants that restrict or prohibit our ability to enter into a variety of transactions and may limit our ability to finance future operations or capital needs.

The agreements governing our 4.03% Senior Notes due in 2018 issued April 21, 2011 and our unsecured revolving line of credit facility contain various covenants that may limit our discretion in operating our business. In particular, we are limited in our ability to merge, consolidate, reorganize or transfer substantially all of our assets, make investments, pay dividends or distributions, redeem or repurchase stock, change the nature of our business, enter into transactions with affiliates, incur indebtedness and create liens on our assets to secure debt. In addition, we are required to meet certain financial covenants. These restrictions could limit our ability to obtain future financing, make strategic acquisitions or needed capital expenditures, withstand economic downturns in our business or the economy in general, conduct operations or otherwise take advantage of business opportunities that may arise.

A failure to comply with the restrictions contained in the agreements could lead to an event of default, which could result in an acceleration of our indebtedness. In the event of an acceleration, we may not have or be able to obtain sufficient funds to refinance our indebtedness or make the required accelerated payments. If we default on our indebtedness, our business financial condition and results of operation could be materially and adversely affected.

The majority of our indebtedness is subject to variable interest rates, which makes us vulnerable to increases in interest rates.

Our indebtedness exposes us to interest rate increases because the majority of our indebtedness is subject to variable rates. At present, we do not have any derivative financial instruments such as interest rate swaps or hedges to mitigate interest rate variability. The interest rates under our credit facilities are reset at varying periods. These interest rate adjustments could expose our operating results and cash flows to periodic fluctuations. Our annual debt service obligations increase by approximately $2.0 million per year for each 1% increase in the average interest rate we pay, based on the $196.5 million balance of variable rate debt outstanding at December 31, 2011. If interest rates rise in the future, and particularly, if they rise significantly, interest expense will increase and our net income will be negatively affected.

Our effective tax rate may change and become less predictable as our business expands.

We continue to consider expansion opportunities domestically and internationally for our rental businesses, such as the organic expansion of our modular business in North Carolina, Georgia, Maryland, Virginia and Washington, D.C., recent expansion into the portable storage and environmental test equipment businesses and our expansion into the liquid and solid containment business. Since the Company’s effective tax rate depends on business levels, personnel and assets located in various jurisdictions, further expansion into new markets or acquisitions may change the effective tax rate in the future and may make it, and consequently our earnings, less predictable going forward. In addition, the enactment of tax law changes by federal and state taxing authorities may impact the Company’s current period tax provision and its deferred tax liabilities.

-20-

Changes in financial accounting standards may cause lower than expected operating results and affect our reported results of operations.

Changes in accounting standards and their application may have a significant effect on our reported results on a going forward basis and may also affect the recording and disclosure of previously reported transactions. New accounting pronouncements and varying interpretations of accounting pronouncements have occurred and may occur in the future. Changes to existing rules or the questioning of current practices may adversely affect our reported financial results or the way we conduct our business.

Failure to comply with internal control attestation requirements could lead to loss of public confidence in our financial statements and negatively impact our stock price.

As a public reporting company, we are required to comply with the Sarbanes-Oxley Act of 2002, including Section 404, and the related rules and regulations of the SEC, including expanded disclosures and accelerated reporting requirements. Compliance with Section 404 and other requirements has and will continue to increase our costs and require additional management resources. We may need to continue to implement additional finance and accounting systems, procedures and controls to satisfy new reporting requirements. While our management concluded that our internal control over financial reporting as of December 31, 2011 was effective, there is no assurance that future assessments of the adequacy of our internal controls over financial reporting will be favorable. If we are unable to obtain future unqualified reports as to the effectiveness of our internal control over financial reporting, investors could lose confidence in the reliability of our internal control over financial reporting, which could adversely affect our stock price.

SPECIFIC RISKS RELATED TO OUR RELOCATABLE MODULAR BUILDINGS BUSINESS SEGMENT:

Significant reductions of, or delays in, funding to public schools have caused the demand and pricing for our modular classroom units to decline, which has resulted in a reduction in our revenues and profitability.

Rentals and sales of modular buildings to public school districts for use as classrooms, restroom buildings, and administrative offices for K-12 represent a significant portion of Mobile Modular’s rental and sales revenues. Funding for public school facilities is derived from a variety of sources including the passage of both statewide and local facility bond measures, developer fees and various taxes levied to support school operating budgets. Many of these funding sources are subject to financial and political considerations, which vary from district to district and are not tied to demand. Historically, we have benefited from the passage of facility bond measures and believe these are essential to our business.

The state of California is our largest market for classroom rentals. The strength of this market depends heavily on public funding from voter passage of both state and local facility bond measures, and the ability of the state to sell such bonds in the public market. A lack of passage of state and local facility bond measures, or the inability to sell bonds in the public markets could reduce our revenues and operating income, and consequently have a material adverse effect on the Company’s financial condition. Furthermore, even if voters have approved facility bond measures and the state has raised bond funds, there is no guarantee that individual school projects will be funded in a timely manner.

As a consequence of the recent economic recession, many states and local governments have experienced large budget deficits resulting in severe budgetary constraints among public school districts. To the extent public school districts’ funding is reduced for the rental and purchase of modular buildings, our business could be harmed and our results of operations negatively impacted. We believe that interruptions or delays in the passage of facility bond measures or completion of state budgets, an insufficient amount of state funding, a significant reduction of funding to public schools, or changes negatively impacting enrollment may reduce the rental and sale demand for our educational products. Any reductions in funding available to the school districts from the states in which we do business may cause school districts to experience budget shortfalls and to reduce their demand for our products despite growing student populations, class size reduction initiatives and modernization and reconstruction project needs, which could reduce our revenues and operating income and consequently have a material adverse effect on the Company’s financial condition.

Public policies that create demand for our products and services may change.

In California a law was enacted in 1996 to provide funding for school districts for the reduction of class sizes for kindergarten through third grade. In Florida, a state constitutional amendment was passed in 2002 to limit the number of students that may be grouped in a single classroom for pre-kindergarten through grade twelve. School districts with class sizes in excess of state limits have

-21-

been and continue to be a significant source of our demand for modular classrooms. Further, in California, efforts to address aging infrastructure and deferred maintenance have resulted in modernization and reconstruction projects by public school districts including seismic retrofitting, asbestos abatement and various building repairs and upgrades. The recent economic recession has caused state and local budget shortfalls, which have reduced school districts’ funding and their ability to comply with state class size reduction requirements in California and Florida. If educational priorities and policies shift away from class-size reduction or modernization and reconstruction projects, demand and pricing for our products and services may decline, not grow as quickly as, or reach the levels that we anticipate. Significant equipment returns may result in lower utilization until equipment can be redeployed or sold, which may cause rental rates to decline and negatively affect our revenues and operating income.

Failure to comply with applicable regulations could harm our business and financial condition, resulting in lower operating results and cash flows.

Similar to conventionally constructed buildings, the modular building industry, including the manufacturers and lessors of portable classrooms, are subject to regulations by multiple governmental agencies at the federal, state and local level relating to environmental, zoning, health, safety and transportation matters, among other matters. Failure to comply with these laws or regulations could impact our business or harm our reputation and result in higher capital or operating expenditures or the imposition of penalties or restrictions on our operations.

As with conventional construction, typically new codes and regulations are not retroactively applied. Nonetheless, new governmental regulations in these or other areas may increase our acquisition cost of new rental equipment, limit the use of or make obsolete some of our existing equipment, or increase our general and administrative costs.

Building codes are generally reviewed every three years. All aspects of a given code are subject to change including, but not limited to, such items as structural specifications for earthquake safety, energy efficiency and environmental standards, fire and life safety, transportation, lighting and noise limits. On occasion, state agencies have undertaken studies of indoor air quality and noise levels with a focus on permanent and modular classrooms. These results could impact our existing modular equipment, and affect the future construction of our modular product.

Compliance with building codes and regulations entail a certain amount of risk as state and local government authorities do not necessarily interpret building codes and regulations in a consistent manner, particularly where applicable regulations may be unclear and subject to interpretation. These regulations often provide broad discretion to governmental authorities that oversee these matters, which can result in unanticipated delays or increases in the cost of compliance in particular markets. The construction and modular industries have developed many “best practices” which are constantly evolving. Some of our peers and competitors may adopt practices that are more or less stringent than the Company’s. When, and if, regulatory standards are clarified, the effect of the clarification may be to impose rules on our business and practices retroactively, at which time, we may not be in compliance with such regulations and we may be required to incur costly remediation. If we are unable to pass these increased costs on to our customers, our profitability, operating cash flows and financial condition could be negatively impacted.

Expansions of our modular operations into new markets will affect our operating results.

We have established modular operations in California, Texas and Florida. We launched operations in North Carolina and Georgia in late 2007 and in Maryland, Virginia and Washington, D.C. during 2008. There are risks inherent in the undertaking of such expansion, including the risk of revenue from the business in these markets not meeting our expectations, higher than expected costs in entering these new markets, risk associated with compliance with applicable state and local laws and regulations, response by competitors and unanticipated consequences of expansion. In addition, expansion in new markets may be affected by local economic and market conditions. Expansion of our operations into these new markets will require a significant amount of attention from our management, a commitment of financial resources and will require us to add qualified management in these markets.

We are subject to laws and regulations governing government contracts. These laws and regulations make these government contracts more favorable to government entities than other third parties and any changes in these laws and regulations, or the failure to comply with these laws and regulations could harm our business.

We have agreements relating to the sale of our products to government entities and, as a result, we are subject to various statutes and regulations that apply to companies doing business with the government. The laws governing government contracts can differ

-22-

from the laws governing private contracts. For example, many government contracts contain pricing terms and conditions that are not applicable to private contracts such as clauses that allow government entities not to perform on contractual obligations in the case of a lack of fiscal funding. Also, in the educational markets we serve, we are able to utilize “piggyback” contracts in marketing our products and services and ultimately to book business. The term “piggyback contract” refers to contracts for portable classrooms or other products entered into by public school districts following a formal bid process that allows for the use of the same contract terms and conditions with the successful vendor by other public school districts. As a result, “piggyback” contracts allow us to more readily book orders from our government customers, primarily public school districts, and to reduce the administrative expense associated with booking these orders. The governmental statutes and regulations that allow for use of “piggyback” contracts are subject to change or elimination in their entirety. A change in the manner of use or the elimination of “piggyback” contracts would likely negatively impact our ability to book new business from these government customers and could cause our administrative expenses related to processing these orders to increase significantly. In addition, any failure to comply with these laws and regulations might result in administrative penalties or even in the suspension of these contracts and as a result, the loss of the related revenues which would harm our business and results from operations.

Seasonality of our educational business may have adverse consequences for our business.

A significant portion of the modular sale and rental revenues is derived from the educational market. Typically, during each calendar year, our highest numbers of classrooms are shipped for rental and sale orders during the second and third quarters for delivery and installation prior to the start of the upcoming school year. The majority of classrooms shipped in the second and third quarters have rental start dates during the third quarter, thereby making the fourth quarter the first full quarter of rental revenues recognized for these transactions.

We face strong competition in our modular building markets.

The modular building leasing industry is highly competitive in our states of operation and we expect it to remain so. The competitive market in which we operate may prevent us from raising rental fees or sales prices to pass any increased costs on to our customers. We compete on the basis of a number of factors, including equipment availability, quality, price, service, reliability, appearance, functionality and delivery terms. We may experience pricing pressures in our areas of operation in the future as some of our competitors seek to obtain market share by reducing prices.

Some of our larger national competitors in the modular building leasing industry, notably Williams Scotsman International, Inc. and Modspace, have a greater range of products and services, greater financial and marketing resources, larger customer bases, and greater name recognition than we have. These larger competitors may be better able to respond to changes in the relocatable modular building market, to finance acquisitions, to fund internal growth and to compete for market share, any of which could harm our business.

We may not be able to quickly redeploy modular units returning from leases.

As of December 31, 2011, 58% of our modular portfolio had equipment on rent for periods exceeding the original committed term. Generally, when a customer continues to rent the modular units beyond the contractual term, the equipment rents on a month-to-month basis. If a significant number of our rented modular units were returned during a short period of time, particularly those units that are rented on a month-to-month basis, a large supply of units would need to be remarketed. Our failure to effectively remarket a large influx of units returning from leases could negatively affect our financial performance and our ability to continue expanding our rental fleet.

Significant increases in raw material and labor costs could increase our acquisition cost of new modular rental units and repair and maintenance costs of our fleet, which would increase our operating costs and harm our profitability.

We incur labor costs and purchase raw materials, including lumber, siding and roofing and other products to perform periodic repairs, modifications and refurbishments to maintain physical conditions of our modular units. The volume, timing and mix of maintenance and repair work on our rental equipment may vary quarter-to-quarter and year-to-year. Generally, increases in labor and raw material costs will also increase the acquisition cost of new modular units and increase the repair and maintenance costs of our fleet. We also maintain a fleet of service trucks and use subcontractor companies for the delivery, set-up, return delivery and

-23-

dismantle of modulars for our customers. We rely on our subcontractor service companies to meet customer demands for timely shipment and return, and the loss or inadequate number of subcontractor service companies may cause prices to increase, while negatively impacting our reputation and operating performance. During periods of rising prices for labor, raw materials or fuel, and in particular, when the prices increase rapidly or to levels significantly higher than normal, we may incur significant increases in our acquisition costs for new modular units and incur higher operating costs that we may not be able to recoup from our customers, which would reduce our profitability.

Failure by third parties to manufacture our products timely or properly may harm our reputation and financial condition.

We are dependent on third parties to manufacture our products even though we are able to purchase products from a variety of third-party suppliers. Mobile Modular purchases new modulars from various manufacturers who build to Mobile Modular’s design specifications. With the exception of Enviroplex, none of the principal suppliers are affiliated with the Company. During 2011, Mobile Modular purchased 29% of its modular product from one manufacturer. The Company believes that the loss of any of its primary manufacturers of modulars could have an adverse effect on its operations since Mobile Modular could experience higher prices and longer delivery lead times for modular product until other manufacturers were able to increase their production capacity.

Failure to properly design, manufacture, repair and maintain the modular product may result in impairment charges, potential litigation and reduction of our operating results and cash flows.

We estimate the useful life of the modular product to be 18 years with a residual value of 50%. However, proper design, manufacture, repairs and maintenance of the modular product during our ownership is required for the product to reach the estimated useful life of 18 years with a residual value of 50%. If we do not appropriately manage the design, manufacture, repair and maintenance of our modular product, or otherwise delay or defer such repair or maintenance, we may be required to incur impairment charges for equipment that is beyond economic repair or incur significant capital expenditures to acquire new modular product to serve demand. In addition, these failures may result in personal injury or property damage claims, including claims based on presence of mold, and termination of leases or contracts by customers. Costs of contract performance, potential litigation, and profits lost from termination could accordingly reduce our future operating results and cash flows.

Our warranty costs may increase.

Sales of new relocatable modular buildings not manufactured by us are typically covered by warranties provided by the manufacturer of the products sold. We provide ninety-day warranties on certain modular sales of used rental units and one-year warranties on equipment manufactured by our Enviroplex subsidiary. Historically, our warranty costs have not been significant, and we monitor the quality of our products closely. If a defect were to arise in the installation of our equipment at the customer’s facilities or in the equipment acquired from our suppliers or by our Enviroplex subsidiary, we may experience increased warranty claims. Such claims could disrupt our sales operations, damage our reputation and require costly repairs or other remedies, negatively impacting revenues and operating income.

SPECIFIC RISKS RELATED TO OUR ELECTRONIC TEST EQUIPMENT BUSINESS SEGMENT:

Market risk and cyclical downturns in the industries using test equipment may result in periods of low demand for our product resulting in excess inventory, impairment charges and reduction of our operating results and cash flows.

TRS-RenTelco’s revenues are derived from the rental and sale of general purpose, communications and environmental test equipment to a broad range of companies, from Fortune 500 to middle and smaller market companies, in the aerospace, defense, communications, manufacturing and semiconductor industries. Electronic test equipment rental and sales revenues are primarily affected by the business activity within these industries related to research and development, manufacturing, and communication infrastructure and maintenance. Historically, these industries have been cyclical and have experienced periodic downturns, which have a material adverse impact on the industry’s demand for equipment, including the electronic test equipment rented by us. In addition, the severity and length of any downturn in an industry may also affect overall access to capital, which could adversely affect our customers. During periods of reduced and declining demand for test equipment, we are exposed to additional receivable risk from non-payment and may need to rapidly align our cost structure with prevailing market conditions.

-24-

Seasonality of our electronic test equipment business may impact quarterly results.

Generally, rental activity declines in the fourth quarter month of December and the first quarter months of January and February. These months may have lower rental activity due to holiday closures, particularly by larger companies, inclement weather and its impact on various field related communications equipment rentals, and companies’ operational recovery from holiday closures which may impact the start-up of new projects coming online in the first quarter. These seasonal factors may impact quarterly results in each year’s first and fourth quarter.

Our rental test equipment may become obsolete, which could result in an impairment charge, or may no longer be supported by a manufacturer.

Electronic test equipment is characterized by changing technology and evolving industry standards that may render our existing equipment obsolete through new product introductions, or enhancements, before the end of its anticipated useful life, causing us to incur impairment charges. We must anticipate and keep pace with the introduction of new hardware, software and networking technologies and acquire equipment that will be marketable to our current and prospective customers.

Additionally, some manufacturers of our equipment may be acquired or cease to exist, resulting in a future lack of support for equipment purchased from those manufacturers. This could result in the remaining useful life to become shorter, causing us to incur an impairment charge. We monitor our manufacturers’ capacity to support their products and the introduction of new technologies, and we acquire equipment that will be marketable to our current and prospective customers. However, an economic downturn could result in unexpected bankruptcies or reduced support from our manufacturers. Failure to properly select, manage and respond to the technological needs of our customers and changes to our products through their technology life cycle may cause certain electronic test equipment to become obsolete, resulting in impairment charges and may negatively impact operating results and cash flows.

If we do not effectively compete in the rental equipment market, our operating results will be materially and adversely affected.

The electronic test equipment rental business is characterized by intense competition from several competitors, including Electro Rent Corporation, Continental Resources, Microlease and TestEquity, some of which may have access to greater financial and other resources than we do. Although no single competitor holds a dominant market share, we face competition from these established entities and new entrants in the market. We believe that we anticipate and keep pace with the introduction of new products and acquire equipment that will be marketable to our current and prospective customers. We compete on the basis of a number of factors, including product availability, price, service and reliability. Some of our competitors may offer similar equipment for lease, rental or sale at lower prices and may offer more extensive servicing, or financing options. Failure to adequately forecast the adoption of, and demand for, new or existing products may cause us not to meet our customers’ equipment requirements and may materially and adversely affect our operating results.

If we are not able to obtain equipment at favorable rates, there could be a material adverse effect on our operating results.

The majority of our rental equipment portfolio is comprised of general purpose test and measurement instruments purchased from leading manufacturers such as Agilent Technologies and Tektronix, a division of Danaher Corporation. We depend on purchasing equipment from these manufacturers and suppliers for use as our rental equipment. If, in the future, we are not able to purchase necessary equipment from one or more of these suppliers on favorable terms, we may not be able to meet our customers’ demands in a timely manner or for a rental rate that generates a profit. If this should occur, we may not be able to secure necessary equipment from an alternative source on acceptable terms and our business may be materially and adversely affected.

-25-

If we are not able to anticipate and mitigate the risks associated with operating internationally, there could be a material adverse effect on our operating results.

Currently, total foreign country customers and operations account for less than 10% of the Company’s revenues and long-lived assets. In recent years some of our customers have expanded their international operations faster than domestic operations, and this trend may continue. Over time, we anticipate the amount of our international business may increase if our focus on international market opportunities continues. Operating in foreign countries subjects the Company to additional risks, any of which may adversely impact our future operating results, including:

•

international political, economic and legal conditions including tariffs and trade barriers;

•

our ability to comply with customs, import/export and other trade compliance regulations, together with any unexpected changes in such regulations;

•

greater difficulty in our ability to recover rental equipment and obtain payment of the related trade receivables;

•

difficulties in attracting and retaining staff and business partners to operate internationally;

•

language and cultural barriers;

•

seasonal reductions in business activities in the countries where our international customers are located;

•

difficulty with the integration of foreign operations;

•

longer payment cycles;

•

currency fluctuations; and

•

potential adverse tax consequences.

Unfavorable currency exchange rates may negatively impact our financial results in U.S. dollar terms.

We receive revenues in Canadian dollars from our business activities in Canada. Conducting business in currencies other than U.S. dollars subjects us to fluctuations in currency exchange rates. If the currency exchange rates change unfavorably, the value of net receivables we receive in foreign currencies and later convert to U.S. dollars after the unfavorable change would be diminished. This could have a negative impact on our reported operating results. We currently do not engage in hedging strategies to mitigate this risk.

SPECIFIC RISKS RELATED TO OUR LIQUID AND SOLID CONTAINMENT TANKS AND BOXES BUSINESS SEGMENT:

We may be brought into tort or environmental litigation or held responsible for cleanup of spills if the customer fails to perform, or an accident occurs in the use of our rental products, which could materially adversely affect our business, future operating results or financial position.

Our rental tanks and boxes are used by our customers to store non hazardous and certain hazardous liquids on the customer’s site. Our customers are generally responsible for proper operation of our tank and box rental equipment while on rent and returning a cleaned and undamaged container upon completion of use, but exceptions may be granted and we cannot always assure that these responsibilities are fully met in all cases. Although we require the customer to carry commercial general liability insurance in a minimum amount of $5,000,000, such policies often contain pollution exclusions and other exceptions. Furthermore, we cannot be sure our liability insurance will always be sufficient. In addition, if an accident were to occur involving our rental equipment or a spill of substances were to occur when the tank or box was in transport or on rent with our customer, a claim could be made against us as owner of the rental equipment.

In the event of a spill or accident, we may be brought into a lawsuit or enforcement action by either our customer or a third party on numerous potential grounds, including that an inherent flaw in a tank or box contributed to the accident or that the tank had suffered some undiscovered harm from a previous customer’s prior use. In the event of a spill caused by our customers, we may be held responsible for cleanup under environmental laws and regulations concerning obligations of suppliers of rental products to effect remediation. In addition, applicable environmental laws and regulations may impose liability on us for conduct of third parties, or for actions that complied with applicable regulations when taken, regardless of negligence or fault. Substantial damage awards have also been made in certain jurisdictions against lessors of industrial equipment based upon claims of personal injury, property damage, and resource damage caused by the use of various products. While we try to take reasonable precautions that our rental equipment is in good and safe condition prior to rental and carry insurance to protect against certain risks of loss or accidents, liability could adversely impact our profitability.

-26-

The liquid and solid storage and containment rental industry is highly competitive, and competitive pressures could lead to a decrease in our market share or in rental rates and our ability to rent, or sell, equipment at favorable prices.

The liquid and solid storage and containment rental industry is highly competitive. We compete against national, regional and local companies, including BakerCorp and Rain For Rent, both of which are significantly larger than we are and both of which have greater financial and marketing resources than we have. Some of our competitors also have longer operating histories, lower cost basis of rental equipment, lower cost structures and more established relationships with equipment manufacturers than we have. In addition, certain of our competitors are more geographically diverse than we are and have greater name recognition among customers than we do. As a result, our competitors that have these advantages may be better able to attract customers and provide their products and services at lower rental rates. We may in the future encounter increased competition in the markets that we serve from existing competitors or from new market entrants.

We believe that equipment quality, service levels, rental rates and fleet size are key competitive factors in the liquid and solid containment storage rental industry. From time to time, we or our competitors may attempt to compete aggressively by lowering rental rates or prices. Competitive pressures could adversely affect our revenues and operating results by decreasing our market share or depressing the rental rates. To the extent we lower rental rates or increase our fleet in order to retain or increase market share, our operating margins would be adversely impacted. In addition, we may not be able to match a larger competitor’s price reductions or fleet investment because of its greater financial resources, all of which could adversely impact our operating results through a combination of a decrease in our market share, revenues and decreased operating income.

Market risk, commodity price volatility, regulatory changes or interruptions and cyclical downturns in the industries using tanks and boxes may result in periods of low demand for our products resulting in excess inventory, impairment charges and reduction of our operating results and cash flows.

Adler Tanks’ revenues are derived from the rental of tanks and boxes to companies involved in oil and gas exploration, extraction and refinement, environmental remediation and wastewater/groundwater treatment, infrastructure construction and various industrial services, among others. We expect tank and box rental revenues will primarily be affected by the business activity within these industries. Historically, these industries have been cyclical and have experienced periodic downturns, which have a material adverse impact on the industry’s demand for equipment, including the tanks and boxes rented by us. Lower oil or gas prices may have an adverse effect on our liquid and solid containment tank and boxes business if the price reduction causes customers to limit or stop exploration, extraction or refinement activities, resulting in lower demand and pricing for renting Adler Tank’s products. Also, a weak U.S. economy may negatively impact infrastructure construction and industrial activity, which may also adversely affect our business.

Changes in regulatory, or governmental, oversight of hydraulic fracturing could materially adversely affect the demand for our rental products and reduce our operating results and cash flows.

We believe that in recent years growing demand related to hydraulic fracturing has increased the total market size and accounted for approximately one third or more of total market rental revenue in 2011. Oil and gas exploration and extraction (including use of tanks for hydraulic fracturing of gas and oil shale) are subject to numerous local, state and federal regulations. The hydraulic fracturing method of extraction has come under scrutiny in several states and by the Federal government due to the potential adverse effects that hydraulic fracturing, and the liquids and chemicals used, may have on water quality and public health. In addition, the disposal of wastewater from the hydraulic fracturing process into injection wells may increase the rate of seismic activity near drill sites and could result in regulatory changes, delays or interruption of future activity. Changes in these regulations could limit, interrupt, or stop exploration and extraction activities, which would negatively impact the demand for our rental products. Finally, it is possible that changes in the technology utilized in hydraulic fracturing could make it less dependent on liquids and therefore lower the related requirements for the use of our rental products.

Seasonality of the liquid and solid storage and containment rental industry may impact quarterly results.

Rental activity may decline in the fourth quarter month of December and the first quarter months of January and February. These months may have lower rental activity in parts of the country where inclement weather may delay, or suspend, a company’s project. The impact of these delays may be to decrease the number of tanks, or boxes, on rent until companies are able to resume their projects when weather improves. These seasonal factors may impact quarterly results in each year’s first and fourth quarter.

-27-

Significant increases in raw material, fuel and labor costs could increase our acquisition and operating costs of rental equipment, which would increase operating costs and decrease profitability.

Increases in raw material costs such as steel and labor to manufacture liquid and solid storage containment tanks and boxes would increase the cost of acquiring new equipment. These price increases could materially adversely impact our financial condition and results of operations if we were not able to recoup these increases through higher rental revenues. In addition, a significant amount of revenues are generated from the transport of rental equipment to and from customers. We own delivery trucks, employ drivers and utilize subcontractors to provide these services. The price of fuel can be unpredictable and beyond our control. During periods of rising fuel and labor costs, and in particular when prices increase rapidly, we may not be able recoup these costs from our customers, which would reduce our profitability.

Failure by third parties to manufacture our products timely or properly may harm our ability to meet customer demand and harm our financial condition.

We are dependent on a variety of third party companies to manufacture equipment to be used in our rental fleet. With the exception of Sabre Manufacturing, LLC, which is owned by the President of our Adler Tanks division, none of the manufacturers are affiliated with the Company. In some cases, we may not be able to procure equipment on a timely basis to the extent that manufacturers for the quantities of equipment we need are not able to produce sufficient inventory on schedules that meet our delivery requirements. In particular, we have seen weather-related slowdowns of manufacturing activity in the Northeast region of the U.S. in past winters. If demand for new equipment increases significantly, especially during a seasonal slowdown, manufacturers may not be able to meet customer orders on a timely basis. As a result, we at times may experience long lead-times for certain types of new equipment and we cannot assure that we will be able to acquire the types or sufficient numbers of the equipment we need to grow our rental fleet as quickly as we would like.

We derive a significant amount of our revenue in our liquid and solid containment tank and boxes business from a limited number of customers, the loss of one or more of which could have an adverse effect on our business.

A significant portion of our revenue in our liquid and solid containment tank and boxes business is generated from a few major customers. Although we have some long-term relationships with our major customers, we cannot be assured that our customers will continue to use our products or services or that they will continue to do so at historical levels. The loss of any significant customer, the failure to collect a significant receivable from a significant customer, any material reduction in orders by a significant customer or the cancellation of a significant customer order could significantly reduce our revenues and consequently harm our financial condition and our ability to fund our operations and service our debt.

We may not be able to quickly redeploy equipment returning from leases at equivalent prices.

Many of our rental transactions are short-term in nature with pricing established on a daily basis. The length of time that a customer needs equipment can often be difficult to determine and can be impacted by a number of factors such as weather, customer funding and project delays. In addition, our equipment is primarily used in the industrial plant services, environmental remediation, infrastructure construction, and oil and gas industries. Changes in the economic conditions facing any of those industries could result in a significant number of units returning off rent, both for us and our competitors.

If the supply of rental equipment available on the market significantly increases due to units coming off rent, demand for and pricing of our rental products could be adversely impacted. We may experience delays in remarketing our off-rent units to new customers. Actions in these circumstances by our competitors may also depress the market price for rental units. These delays and price pressures would adversely affect equipment utilization levels and total revenues, which would reduce our profitability.

Adjusted EBITDA

To supplement the Company’s financial data presented on a basis consistent with accounting principles generally accepted in the U.S. (“GAAP”), the Company presents Adjusted EBITDA, which is defined by the Company as net income before minority interest in income of subsidiary, interest expense, provision for income taxes, depreciation, amortization, and non-cash stock-based compensation. The Company presents Adjusted EBITDA as a financial measure as management believes it provides useful information to investors regarding the Company’s liquidity and financial condition and because management, as well as the Company’s lenders, use this measure in evaluating the performance of the Company.

Management uses Adjusted EBITDA as a supplement to GAAP measures to further evaluate the Company’s period-to-period operating performance, compliance with financial covenants in the Company’s revolving lines of credit and senior notes, and to evaluate the Company’s ability to meet future capital expenditure and working capital requirements. Management believes the exclusion of non-cash charges, including stock-based compensation, is useful in measuring the Company’s cash available to operations and the performance of the Company. Because management finds Adjusted EBITDA useful, the Company believes its investors will also find Adjusted EBITDA useful in evaluating the Company’s performance.

Adjusted EBITDA should not be considered in isolation or as a substitute for net income, cash flows, or other consolidated income or cash flow data prepared in accordance with GAAP in the U.S. or as a measure of the Company’s profitability or liquidity. Adjusted EBITDA is not in accordance with or an alternative for GAAP, and may be different from non—GAAP measures used by other companies. Unlike EBITDA, which may be used by other companies or investors, Adjusted EBITDA does not include stock-based compensation charges. The Company believes that Adjusted EBITDA is of limited use in that it does not reflect all of the amounts associated with the Company’s results of operations as determined in accordance with GAAP and does not accurately reflect real cash flow. In addition, other companies may not use Adjusted EBITDA or may use other non-GAAP measures, limiting the usefulness of Adjusted EBITDA for purposes of comparison. The Company’s presentation of Adjusted EBITDA should not be construed as an inference that the Company will not incur expenses that are the same as or similar to the adjustments in this presentation. Therefore, Adjusted EBITDA should only be used to evaluate the Company’s results of operations in conjunction with the corresponding GAAP measures. The Company compensates for the limitations of Adjusted EBITDA by relying upon GAAP results to gain a complete picture of the Company’s performance. Because Adjusted EBITDA is a non-GAAP financial measure, as defined by the Securities and Exchange Commission, the Company includes in the tables below reconciliations of Adjusted EBITDA to the most directly comparable financial measures calculated and presented in accordance with GAAP.

In November of 2007, the Company purchased the remaining minority interest in Enviroplex, a classroom manufacturing business selling modular classrooms in California.

Adjusted EBITDA is defined as net income before minority interest in income of subsidiary, interest expense, provision for income taxes, depreciation, amortization, non-cash stock-based compensation and non-cash impairment charges.

Adjusted EBITDA Margin is calculated as Adjusted EBITDA divided by total revenues for the period.

Adjusted EBITDA is a component of two restrictive financial covenants for the Company’s unsecured line of credit and senior notes. These instruments contain financial covenants requiring the Company to not:

•

Permit the consolidated fixed charge coverage ratio of Adjusted EBITDA (as defined) to fixed charges as of the end of any fiscal quarter to be less than 2.00 to 1. At December 31, 2011 the actual ratio for the line of credit and the senior notes was 5.45 to 1 and 4.35 to 1, respectively.

•

Permit the consolidated leverage ratio of funded debt to Adjusted EBITDA (as defined) at any time during any period of four consecutive quarters to be greater than 2.50 to 1. At December 31, 2011 the actual ratio was 1.84 to 1.

At December 31, 2011, the Company was in compliance with each of these aforementioned covenants. There are no anticipated trends that the Company is aware of that would indicate non-compliance with these covenants, though, significant deterioration in our financial performance could impact the Company’s ability to comply with these covenants.

ITEM 7.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS.

The following Management’s Discussion and Analysis of Financial Condition and Results of Operations contains forward-looking statements that involve risks and uncertainties. The Company’s actual results could differ materially from those anticipated in these forward-looking statements as a result of certain factors, including those set forth in this section as well as those discussed under Part I, “Item 1A. Risk Factors” and elsewhere in this document. This discussion should be read together with the financial statements and the related notes thereto set forth in “Item 8. Financial Statements and Supplementary Data.”

Results of Operations

General

The Company, incorporated in 1979, is a leading rental provider of relocatable modular buildings for classroom and office space, electronic test equipment for general purpose and communications needs, and liquid and solid containment tanks and boxes. The Company’s primary emphasis is on equipment rentals. The Company is comprised of four business segments: (1) its modular building rental division (“Mobile Modular”); (2) its electronic test equipment rental division (“TRS-RenTelco”); (3) its containment solutions for the storage of hazardous and non-hazardous liquids and solids division (“Adler Tanks”); and (4) its classroom manufacturing business selling modular buildings used primarily as classrooms in California (“Enviroplex”). In 2011, Mobile Modular, TRS-RenTelco, Adler Tanks and Enviroplex contributed 24%, 36%, 38% and 2%, respectively, of the Company’s income before provision for taxes (the equivalent of “pretax income”), compared to 43%, 33%, 24% and 0%, respectively, for 2010. Although managed as a separate business unit, Enviroplex’s revenues, pretax income contribution and total assets are not significant relative to the Company’s consolidated financial position.

The Company generates the majority of its revenue from the rental of relocatable modular buildings, electronic test equipment and liquid and solid containment tanks and boxes on operating leases with sales of equipment occurring in the normal course of business. The Company requires significant capital outlay to purchase its rental inventory and recovers its investment through rental and sales revenues. Rental revenue and other services negotiated as part of the lease agreement with the customer and related costs are recognized on a straight-line basis over the term of the lease. Sales revenue and related costs are recognized upon delivery and installation of the equipment to the customer. Sales revenues are less predictable and can fluctuate from period to period depending on customer demands and requirements. Generally, rental revenues recover the equipment’s capitalized cost in a short period of time relative to the equipment’s rental life and when sold, sale proceeds are usually above its net book value. The Company’s growth in rental assets has been primarily funded through internal cash flow and conventional bank financing.

The Company’s rental operations include rental and rental related service revenues which comprised approximately 80% of the Company’s total revenues in 2011 and total revenues for the three years ended December 31, 2011. Over the past three years modulars comprised approximately 45%, electronic test equipment comprised approximately 36% and tanks and boxes comprised approximately 19% of the cumulative rental operations revenues. The Company’s direct costs of rental operations include depreciation of rental equipment, rental related service costs, impairment of rental equipment, and other direct costs of rental operations (which include direct labor, supplies, repairs, insurance, property taxes, license fees and amortization of certain lease costs).

The Company sells modular, electronic test equipment and liquid and solid containment tanks and boxes that are new, or previously rented. The Company’s Enviroplex subsidiary manufactures and sells modular classrooms. The renting and selling of some modular equipment requires a dealer’s license, which the Company has obtained from the appropriate governmental agencies. Sales and other revenues of modular, electronic test equipment and tanks and boxes have comprised approximately 20% of the Company’s consolidated revenues in 2011 and over the last three years. During these three years, modulars comprised approximately 60% and electronics represented approximately 40% of sales and other revenues. The Company’s cost of sales includes the carrying value of the equipment sold and the direct costs associated with the equipment sold such as delivery, installation, modifications and related site work.

The rental and sale of modulars to public school districts comprised 16%, 22% and 28% of the Company’s consolidated rental and sales revenues for 2011, 2010 and 2009, respectively. (For more information, see “Item 1. Business—Relocatable Modular Buildings—Classroom Rentals and Sales to Public Schools (K-12)” above.)

-35-

Selling and administrative expenses primarily include personnel and benefit costs, depreciation and amortization, bad debt expense, advertising costs, and professional service fees. The Company believes that sharing of common facilities, financing, senior management, and operating and accounting systems by all of the Company’s operations, results in an efficient use of overhead. Historically, the Company’s operating margins have been impacted favorably to the extent its costs and expenses are leveraged over a large installed customer base. However, there can be no assurance as to the Company’s ability to maintain a large installed customer base or ability to sustain its historical operating margins.

Related Party Transactions

During the years ended December 31, 2011 and 2010, the Company acquired liquid and solid containment tanks totaling $30.3 million and $16.8 million, respectively from Sabre Manufacturing, LLC, which is controlled by the President of Adler Tanks. In addition, the Company leased two operating facilities and received certain support services from companies controlled by the President of Adler Tanks. Payments for these leases and services totaled $0.2 million and $0.6 million in 2011 and 2010, respectively.

Twelve Months Ended December 31, 2011 Compared to

Twelve Months Ended December 31, 2010

Overview

The Company’s total revenues in 2011 increased 18%, to $342.7 million from $291.4 million in 2010. The Company’s total net income in 2011 increased 36%, to $49.6 million, or $2.00 per diluted share, from $36.5 million, or $1.50 per diluted share, in 2010. The Company’s year over year total revenue increase was due to higher rental, rental related services and sales revenues as more fully described below.

For 2011 compared to 2010, on a consolidated basis,

•

Gross profit increased $36.0 million, or 28%, to $166.8 million, which was comprised of an increase in Adler Tanks’ gross profit of $21.9 million or 79% due to higher gross profit on rents and rental related services revenues, an increase in TRS-RenTelco’s gross profit of $13.6 million or 31% due to higher gross profit on rental and sales revenues and an increase in Enviroplex’s gross profit of $2.2 million primarily due to $9.1 million higher sales revenues, partly offset by a decrease in Mobile Modular’s gross profit of $1.7 million or 3% due to lower gross profit on rental and rental related services revenues, partly offset by higher gross profit on sales revenues.

•

Selling and administrative expenses increased $12.5 million, or 19% to $78.1 million, with the increase primarily due to increased personnel and employee benefit costs.

•

Interest expense increased $1.4 million, to $7.6 million from $6.2 million in 2010 primarily due to higher net average interest rates (2.7% in 2011 compared to 2.4% in 2010) and higher average debt levels of the Company.

•

Pretax income contributions were 39%, 36% and 23% by Adler Tanks, TRS-RenTelco and Mobile Modular, respectively, in 2011, compared to 24%, 33% and 43%, respectively, in 2010. These results are discussed on a segment basis below. Pre-tax income contribution by Enviroplex was 2% in 2011 compared to less than one percent in 2010.

•

Provision for income taxes resulted in an effective tax rate of 38.8%, up from 38.2% in 2010. Looking forward, the Company estimates an effective tax rate of 39.2% in 2012, based on the expected revenue distribution by state. However, there can be no assurance that such expected revenue distribution by state will be achieved, which could cause the Company’s effective tax rate to change.

•

Adjusted EBITDA increased $29.3 million, or 22%, to $161.3 million compared to $132.0 million in 2010. Adjusted EBITDA is a non-GAAP financial measure and is defined as net income before interest expense, provision for income taxes, depreciation, amortization and non-cash stock-based compensation. A reconciliation of Adjusted EBITDA to net cash provided by operating activities and net income to Adjusted EBITDA can be found in “Item 6. Selected Financial Data.” on page 32.

Mobile Modular

For 2011, Mobile Modular’s total revenues decreased $2.1 million, or 2%, to $124.6 million compared to 2010, primarily due to lower rental and sales revenues, partly offset by higher rental related services revenues. The revenue decrease, together with lower gross margin on rental revenues, higher selling and administrative expenses and higher interest expense, resulted in a decrease in pre-tax income of $6.1 million, or 24%, to $19.0 million in 2011.

Mobile Modular’s gross profit for 2011 decreased $1.7 million to $55.2 million from $56.9 million in 2010. For the year ended December 31, 2011 compared to the year ended December 31, 2010:

•

Gross Profit on Rental Revenues—Mobile Modular’s rental revenues decreased $2.7 million, or 3%, compared to 2010, due to 5% lower average monthly rental rates, partly offset by 2% higher average rental equipment on rent. As a percentage of rental revenues, depreciation was 17% in 2011 and 2010 and other direct costs were 28% in 2011 and 2010, which resulted in gross margin percentage of 55% in 2011 and 2010. The lower rental revenues, together with flat rental margins, resulted in gross profit on rental revenues decreasing $1.6 million, or 3%, to $44.2 million from $45.8 million in 2010.

•

Gross Profit on Rental Related Services—Mobile Modular’s rental related services revenues increased $1.1 million, or 5%, compared to 2010. Most of these service revenues are negotiated with the initial lease and are recognized on a straight-line basis with the associated costs over the initial term of the lease. The increase in rental related services revenues was primarily attributable to changes in the mix of leases and the amortization of associated service revenues in 2011 as compared to 2010 and higher delivery and return delivery revenues at Mobile Modular Portable Storage. The higher revenues offset by lower gross margin percentage of 22% in 2011 compared to 25% in 2010 resulted in rental related services gross profit decreasing $0.6 million, or 10%, to $5.2 million from $5.8 million in 2010.

•

Gross Profit on Sales—Mobile Modular’s sales revenues decreased $0.5 million, or 3%, compared to 2010 and gross profit increased $0.4 million, or 9%, primarily due to higher gross margins on sales of new equipment in 2011. Sales occur routinely as a normal part of Mobile Modular’s rental business; however, these sales can fluctuate from period to period depending on customer requirements, equipment availability and funding.

For 2011, Mobile Modular’s selling and administrative expenses increased $3.8 million, or 13%, to $32.1 million from $28.3 million in 2010, primarily as a result of increased investment in our portable storage initiative.

Mobile Modular’s gross profit for 2010 decreased $16.7 million to $56.9 million from $73.6 million in 2009. For the year ended December 31, 2010 compared to the year ended December 31, 2009:

•

Gross Profit on Rental Revenues—Mobile Modular’s rental revenues decreased $9.7 million, or 10%, compared to 2009, primarily due to the decline in demand for commercial buildings and higher returns of classroom buildings in our education markets. The rental revenues decrease was due to 5% lower average monthly rental rates and 5% lower average rental equipment on rent. As a percentage of rental revenues, depreciation was 17% in 2010 and 15% in 2009 and other direct costs were 28% in 2010 compared to 20% in 2009, which resulted in gross margin percentage of 55% in 2010 and 65% in 2009. The lower rental revenues, together with lower rental margins, resulted in gross profit on rental revenues decreasing $14.0 million, or 23%, to $45.8 million from $59.9 million in 2009.

•

Gross Profit on Rental Related Services—Mobile Modular’s rental related services revenues decreased $2.2 million, or 9%, compared to 2009. Most of these service revenues are negotiated with the initial lease and are recognized on a straight-line basis with the associated costs over the initial term of the lease. The decrease in rental related services revenues was primarily attributable to changes in the mix of leases and the amortization of associated service revenues in 2010 as compared to 2009. The lower revenues combined with lower gross margin percentage of 25% in 2010 compared to 26% in 2009 resulted in rental related services gross profit decreasing $0.7 million, or 11%, to $5.8 million from $6.5 million in 2009.

•

Gross Profit on Sales—Mobile Modular’s sales revenues decreased $4.5 million, or 18%, compared to 2009 resulting in lower sales gross profit of $4.9 million in 2010 compared to $6.7 million in 2009. Sales occur routinely as a normal part of Mobile Modular’s rental business; however, these sales can fluctuate from period to period depending on customer requirements, equipment availability and funding.

For 2010, Mobile Modular’s selling and administrative expenses increased $1.0 million, or 4%, to $28.3 million from $27.3 million in 2009, primarily due to higher personnel and employee benefit costs related to the expansion of our portable storage initiative and higher facility rental expenses, and represented 34% of Mobile Modular’s rental revenues in 2010 compared to 30% in 2009.

TRS-RenTelco

For 2010, TRS-RenTelco’s total revenues increased $7.8 million, or 8%, to $107.7 million compared to 2009, primarily due to higher rental and sales revenues. Pre-tax income increased $10.8 million to $19.3 million for 2010 from $8.5 million for 2009, primarily due to higher gross profit on rental and sales revenues and lower interest expense, partly offset by higher selling and administrative expenses.

•

Gross Profit on Rental Revenues—TRS-RenTelco’s rental revenues increased $7.0 million, or 9%, while depreciation expense decreased $3.2 million, or 8%, resulting in an increase of $9.1 million, or 38%, in gross profit on rental revenues to $32.9 million in 2010.

•

Gross Profit on Sales—TRS-RenTelco’s sales revenues increased $0.9 million, or 4%, compared to 2009. Gross margin percentage was 41% in 2010, compared to 33% in 2009, primarily due to higher gross margin on new and used equipment sales resulting in gross profit on sales increasing $2.0 million, or 29%, to $8.8 million from $6.8 million in 2009. Sales occur routinely as a normal part of TRS-RenTelco’s rental business; however, these sales and related gross margins can fluctuate from period to period depending on customer requirements, equipment availability and funding.

For 2010, TRS-RenTelco’s selling and administrative expenses increased $0.5 million, or 2%, to $22.4 million from $21.9 million in 2009, primarily due to investment in the TRS-Environmental growth initiative and higher bad debt expense.

Adler Tanks

For 2010, Adler Tanks’ total revenues increased $20.2 million, or 81%, to $45.2 million compared to 2009, primarily due to higher rental and rental related services revenues during 2010. The revenue increase and higher gross margin on rental revenues resulted in pre-tax income increase of $10.0 million to $14.4 million for the year ended December 31, 2010, an increase of 225% compared to the pre-tax income for the year ended December 31, 2009.

Liquidity and Capital Resources

This section contains statements that constitute “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. See the statements at the beginning of this Item for cautionary information with respect to such forward-looking statements.

The Company’s rental businesses are capital intensive and generate significant cash flows. Cash flows for the Company in 2011 as compared to 2010 are summarized as follows:

Cash Flows from Operating Activities: The Company’s operations provided net cash flow of $129.3 million for 2011, an increase of 29%, as compared to $100.6 million in 2010. The $28.7 million increase in net cash provided by operating activities was primarily due to higher income from operations, increased deferred taxes in 2011 and other balance sheet changes. The increased deferred taxes were primarily due to the impact of additional federal bonus depreciation deductions related to the Company’s capital expenditures in 2011.

Cash Flows from Investing Activities: Net cash used in investing activities was $143.7 million for 2011 as compared to $106.2 million in 2010. The $37.5 million increase in net cash used in investing activities was primarily due to $32.2 million higher purchases of rental equipment of $154.9 million in 2011, compared to $122.7 million in 2010, primarily as a result of increased purchases at Adler Tanks and TRS-RenTelco to meet market demand. In addition, purchase of property, plant and equipment increased $5.1 million 2011, primarily due to acquisition of an operating facility in New Jersey, information technology projects and expansion of the Company’s inventory center in Livermore, California.

Cash Flows from Financing Activities: Net cash provided by financing activities was $14.6 million in 2011as compared to $5.4 million in 2010. The $9.2 million change in net cash flow from financing activities was primarily due to borrowings and repayments on the Company’s bank lines of credit. On April 21, 2011, the Company issued $100.0 million of 4.03% Senior Notes, the proceeds of which was used to repay outstanding borrowings under the Company’s bank lines of credit.

Significant capital expenditures are required to maintain and grow the Company’s rental assets. During the last three years, the Company has financed its working capital and capital expenditure requirements through cash flow from operations, proceeds from the sale of rental equipment and from bank borrowings. Sales occur routinely as a normal part of the Company’s rental business. However, these sales can fluctuate from period to period depending on customer requirements and funding. Although the net proceeds received from sales may fluctuate from period to period, the Company believes its liquidity will not be adversely impacted from lower sales in any given year because it believes it has the ability to increase its bank borrowings and conserve its cash in the future by reducing the amount of cash it uses to purchase rental equipment, pay dividends, or repurchase the Company’s common stock.

As the following table indicates, cash flow provided by operating activities and proceeds from sales of used rental equipment have been greater than rental equipment purchases over the past three years.


Funding of Rental Asset Growth

Cash Available for Other Uses	$	2,801		$	6,543		$	81,176		$	90,520

In addition to increasing its rental assets, the Company had other capital expenditures for property, plant and equipment of $17.2 million in 2011, $12.1 million in 2010, and $2.2 million in 2009, and has used cash to provide returns to its shareholders in the form of cash dividends. The Company paid cash dividends of $22.3 million, $21.4 million and $20.4 million in the years ended December 31, 2011, 2010 and 2009, respectively.

-51-

The Company has in the past made repurchases of shares of its common stock from time to time in the over-the-counter market (NASDAQ) and/or through privately negotiated, block transactions under an authorization from the Board of Directors. Shares repurchased by the Company are canceled and returned to the status of authorized but unissued stock. During the year ended December 31, 2011, 2010 and 2009, the Company did not repurchase any of its common stock. As of February 29, 2012, 2,000,000 shares of the Company’s common stock remain authorized for repurchase.

Unsecured Revolving Lines of Credit

As the Company’s assets have grown, it has been able to negotiate increases in the borrowing limit under its general bank lines of credit. In May 2008, the Company entered into a credit facility with a syndicate of banks (the “Credit Facility”). The Credit Facility provides for a $350.0 million unsecured revolving credit facility and requires the Company to pay interest determined by reference to the Consolidated Leverage ratio (as defined in the Credit Facility). In addition, the Company pays a commitment fee on the daily unused portion of the available facility. The Credit Facility matures on May 14, 2013.

In June 2008, the Company entered into a Credit Facility Letter Agreement with Union Bank, N.A. and a Credit Line Note in favor of Union Bank, N.A., extending its $5.0 million line of credit facility related to its cash management services (“Sweep Service Facility”). The Sweep Service Facility matures on the earlier of May 14, 2013, or the date the Company ceases to utilize Union Bank, N.A. for its cash management services.

At December 31, 2011, under the Credit Facility and the Sweep Service Facility, the Company had unsecured lines of credit that permit it to borrow up to $355.0 million of which $196.5 million was outstanding and had capacity to borrow up to an additional $158.5 million. During the year ended December 31, 2011 the highest and average amounts outstanding under the Credit Facility were $262.5 million and $206.2 million, respectively. The Credit Facility contains financial covenants requiring the Company to not:

•

Permit the Consolidated Fixed Charge Coverage Ratio (as defined) as of the end of any fiscal quarter to be less than 2.00 to 1. At December 31, 2011 the actual ratio was 5.45 to 1.

•

Permit the Consolidated Asset Coverage Ratio (as defined) as of the end of any fiscal quarter to be less than 1.50 to 1. At December 31, 2011 the actual ratio was 2.92 to 1.

•

Permit the Consolidated Leverage Ratio (as defined) at any time during any period of four consecutive quarters to be greater than 2.50 to 1. At December 31, 2011 the actual ratio was 1.84 to 1.

At December 31, 2011, the Company was in compliance with each of the aforementioned covenants. There are no anticipated trends that the Company is aware of that would indicate non-compliance with these covenants, though, significant deterioration in our financial performance could impact the Company’s ability to comply with these covenants.

4.03% Senior Notes Due in 2018

On April 21, 2011, the Company entered into a Note Purchase and Private Shelf Agreement (the “Note Purchase Agreement”) with Prudential Investment Management, Inc., The Prudential Insurance Company of America and Prudential Retirement Insurance and Annuity Company (collectively, the “Purchaser”), pursuant to which the Company agreed to sell an aggregate principal amount of $100 million of its 4.03% Series A Senior Notes (the “Senior Notes”) to the Purchaser. The Senior Notes are an unsecured obligation of the Company, due on April 21, 2018. Interest on these notes is due semi-annually in arrears and the principal is due in five equal annual installments, with the first payment due on April 21, 2014. In addition, the Note Purchase Agreement allows for the issuance and sale of additional senior notes to the Purchaser (the “Shelf Notes”) in the aggregate principal amount of $100 million, to mature no more than 12 years after the date of original issuance thereof, to have an average life of no more than 10 years and to bear interest on the unpaid balance. Among other restrictions, the Note Purchase Agreement, under which the Senior Notes were sold, contains financial covenants requiring the Company to not:

•

Permit the Consolidated Fixed Charge Coverage Ratio of EBITDA (as defined in the Note Purchase Agreement) to fixed charges as of the end of any fiscal quarter to be less than 2.50 to 1. At December 31, 2011, the actual ratio was 4.35 to 1.

•

Permit the Consolidated Leverage Ratio of funded debt to EBITDA (as defined in the Note Purchase Agreement) at any time during any period of four consecutive quarters to be greater than 2.50 to 1. At December 31, 2011, the actual ratio was 1.84 to 1.

•

Permit tangible net worth, calculated as of the last day of each fiscal quarter, to be less than the sum of (i) $229.0 million, plus (ii) 25% of net income for such fiscal quarter subsequent to December 31, 2010, plus (iii) 90% of the net cash proceeds from the issuance of the Company’s capital stock after December 31, 2010. At December 31, 2011, such sum was $246.1 million and the actual tangible net worth of the Company was $331.1 million.

5.08% Senior Notes Due in 2011

In June 2004, the Company completed a private placement of $60.0 million of 5.08% senior notes due in 2011. The final principal payment of $12.0 million was made in June 2011. There was no outstanding balance as of December 31, 2011.

Contractual Obligations and Commitments

At December 31, 2011, the Company’s material contractual obligations and commitments consist of outstanding borrowings under our credit facility expiring in 2013, outstanding amounts under our 4.03% senior notes due in 2018, and operating leases for facilities. The operating lease amounts exclude property taxes and insurance. The table below provides a summary of the Company’s contractual obligations and reflects expected payments due as of December 31, 2011 and does not reflect changes that could arise after that date.

The Company believes that its needs for working capital and capital expenditures through 2012 and beyond will be adequately met by operating cash flow, proceeds from the sale of rental equipment, and bank borrowings.

Please see the Company’s Consolidated Statements of Cash Flows on page 63 for a more detailed presentation of the sources and uses of the Company’s cash.

Critical Accounting Policies

In response to the SEC’s Release No. 33-8040, “Cautionary Advice Regarding Disclosure About Critical Accounting Policies,” the Company has identified the most critical accounting policies upon which its financial status depends. The Company determined its critical accounting policies by considering those policies that involve the most complex or subjective decisions or assessments. The Company has identified that its most critical accounting policies are those related to depreciation, maintenance and repair, impairment of rental equipment and impairment of goodwill and intangible assets. Descriptions of these accounting policies are found in both the notes to the consolidated financial statements and at relevant sections in this management’s discussion and analysis.

Depreciation—The estimated useful lives and estimated residual values used for rental equipment are based on the Company’s experience as to the economic useful life and sale value of its products. Additionally, to the extent information is publicly available, the Company also compares its depreciation policies to other companies with similar rental products for reasonableness.

The lives and residual values of rental equipment are subject to periodic evaluation. For modular equipment, external factors to consider may include, but are not limited to, changes in legislation, regulations, building codes, local permitting, and supply or demand. Internal factors for modulars may include, but are not limited to, change in equipment specifications, condition of equipment, or maintenance policies. For electronic test equipment, external factors to consider may include, but are not limited to, technological advances, changes in manufacturers’ selling prices, and supply or demand. Internal factors for electronic test equipment may include,

but are not limited to, change in equipment specifications, condition of equipment or maintenance policies. For liquid and solid containment tanks and boxes, external factors to consider may include, but are not limited to changes in Federal and State legislation, the types of materials stored and the frequency of moves and uses. Internal factors for liquid and solid containment tanks and boxes may include, but are not limited to, change in equipment specifications and maintenance policies.

Changes in useful lives or residual values will impact depreciation expense and any gain or loss from the sale of used equipment. Depending on the magnitude of such changes, the impact on the financial statements could be significant.

Maintenance, Repair and Refurbishment—Maintenance and repairs are expensed as incurred. The direct material and labor costs of value-added additions or major refurbishment of modular buildings are capitalized to the extent the refurbishment significantly improves the quality and adds value or life to the equipment. Judgment is involved as to when these costs should be capitalized. The Company’s policies narrowly limit the capitalization of value-added items to specific additions such as restrooms, 40 and 60-foot sidewalls and ventilation upgrades. In addition, only major refurbishment costs incurred near the end of the estimated useful life of the rental equipment, which extend its useful life, and are subject to certain limitations, are capitalized. Changes in these policies could impact the Company’s financial results.

Impairment of rental equipment—The carrying value of the Company’s rental equipment is its capitalized cost less accumulated depreciation. To the extent events or circumstances indicate that the carrying value cannot be recovered, an impairment loss is recognized to reduce the carrying value to fair value. The Company determines fair value based upon the condition of the equipment and the projected net cash flows from its sale considering current market conditions. Additionally, if the Company decides to sell or otherwise dispose of the rental equipment, it is carried at the lower of cost or fair value less costs to sell or dispose. Due to uncertainties inherent in the valuation process and market conditions, it is reasonably possible that actual results of operating and disposing of rental equipment could be materially different than current expectations.

Impairment of goodwill and intangible assets—The Company assesses the carrying amount of its recorded goodwill and intangible assets annually or in interim periods if circumstances indicate an impairment may have occurred. The impairment review is performed by first assessing qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test. The two-step process requires management to make certain judgments in determining what assumptions to use in the calculation. The first step in the evaluation consists of estimating the fair value of the reporting unit based on discounted cash flows using revenue and after tax profit estimates. Management then compares its estimate of the fair value of the reporting unit with the reporting unit’s carrying amount, which includes goodwill and intangible assets. If the estimated fair value of the reporting unit exceeds the carrying value of the net assets assigned to that unit, then goodwill and intangible assets are not impaired and no further testing is required. If the carrying value of the net assets assigned to the reporting unit were to exceed its fair value, then the second step is performed in order to determine the implied fair value of the reporting unit’s goodwill and intangible assets and an impairment loss is recorded for an amount equal to the difference between the implied fair value and the carrying value of the goodwill and intangible assets.

Impact of Inflation

Although the Company cannot precisely determine the effect of inflation, from time to time it has experienced increases in costs of rental equipment, manufacturing costs, operating expenses and interest. Because a majority of its rentals are relatively short-term, the Company has generally been able to pass on such increased costs through increases in rental rates and selling prices, but there can be no assurance that the Company will be able to continue to pass on increased costs to customers in the future.

Off Balance Sheet Transactions

As of December 31, 2011, the Company did not have any “off-balance-sheet arrangements,” as defined in Item 303(a)(4)(ii) of Regulation S-K.

ITEM 7A.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

The Company is exposed to cash flow and fair value risk due to changes in interest rates with respect to its 4.03% senior notes due in 2018 and its revolving lines of credit. Weighted average variable rates are based on implied forward rates in the yield curve at December 31, 2011. The estimate of fair value of the Company’s fixed rate debt is based on the borrowing rates currently available to the Company for bank loans with similar terms and average maturities. The table below presents principal cash flows by expected annual maturities, related weighted average interest rates and estimated fair value the Company’s 4.03% senior notes due in 2018 and the Company’s revolving lines of credit as of December 31, 2011.

The Company formed a wholly owned Canadian subsidiary, TRS-RenTelco Inc. in conjunction with the TRS acquisition (see Item 1—Business—History, Strategic Expansion and Acquisitions and Note 2 to the Consolidated Financial Statements). The Canadian operations of the Company subject it to foreign currency risks (i.e. the possibility that the financial results could be better or worse than planned because of changes in foreign currency exchange rates). Currently, the Company does not use derivative instruments to hedge its economic exposure with respect to assets, liabilities and firm commitments denominated in foreign currencies. In 2011, the Company has experienced minimal impact on net income due to foreign exchange rate fluctuations. Although there can be no assurances, given the size of the Canadian operations, the Company does not expect future foreign exchange gains and losses to be significant.

The Company has no derivative financial instruments that expose the Company to significant market risk.

Management’s Report on Internal Control over Financial Reporting

The Company’s management is responsible for the preparation and integrity of the consolidated financial statements appearing in our Annual Report filed on Form 10-K. The consolidated financial statements were prepared in conformity with United States generally accepted accounting principles and include amounts based on management’s estimates and judgments. All other financial information in this report has been presented on a basis consistent with the information included in the financial statements.

The Company’s management is also responsible for establishing and maintaining adequate internal control over financial reporting as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934. The Company maintains a system of internal control that is designed to provide reasonable assurance as to the reliable preparation and presentation of the consolidated financial statements, as well as to safeguard assets from unauthorized use or disposition.

The Company’s system of internal control over financial reporting is embodied in the Company’s Code of Business Conduct and Ethics. It sets the tone of our organization and includes factors such as integrity and ethical values. Our internal control over financial reporting is supported by formal policies and procedures, which are reviewed, modified and improved as changes occur in business conditions and operations.

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

The Audit Committee of the Board of Directors, which is composed solely of outside directors, meets periodically with members of management and the independent auditors to review and discuss internal control over financial reporting, as well as accounting and financial reporting matters. The independent auditors report to the Audit Committee and accordingly have full and free access to the Audit Committee at any time.

The Company’s management conducted an evaluation of the effectiveness of our internal control over financial reporting as of December 31, 2011 based on the criteria set forth in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on its evaluation, management has concluded that, as of December 31, 2011, the Company’s internal control over financial reporting was effective based on those criteria.

Report on Internal Control over Financial Reporting

Board of Directors and Shareholders of McGrath RentCorp and Subsidiaries:

We have audited McGrath RentCorp and Subsidiaries’ internal control over financial reporting as of December 31, 2011, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). McGrath RentCorp and Subsidiaries’ management is responsible 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 Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on McGrath RentCorp and Subsidiaries’ internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

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, McGrath RentCorp and Subsidiaries maintained, in all material respects, effective internal control over financial reporting as of December 31, 2011, based on criteria established in Internal Control—Integrated Framework issued by COSO.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the accompanying consolidated balance sheets of McGrath RentCorp and Subsidiaries as of December 31, 2011 and 2010 and the related consolidated statements of income, shareholders’ equity and cash flows for each of the three years in the period ended December 31, 2011, and our report dated February 29, 2012 expressed an unqualified opinion thereon.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1.

ORGANIZATION AND BUSINESS

McGrath RentCorp (the “Company”) is a California corporation organized in 1979. The Company is a diversified business to business rental company with three rental products; relocatable modular buildings, electronic test equipment and liquid and solid containment tanks and boxes. Although the Company’s primary emphasis is on equipment rentals, sales of equipment occur in the normal course of business. The Company is comprised of four business segments: its modular building division (“Mobile Modular”), its electronic test equipment division (“TRS-RenTelco”), its containment solutions for the storage of hazardous and non-hazardous liquids and solids division (“Adler Tanks”) and its classroom manufacturing division selling modular classrooms in California (“Enviroplex”).

Significant risks of rental equipment ownership are borne by the Company, which include, but are not limited to, uncertainties in the market for its products over the equipment’s useful life, use limitations for modular equipment related to updated building codes or legislative changes, technological obsolescence of electronic test equipment, changes in Federal and State laws regulating liquid and solid containment storage, environmental litigation and rental equipment deterioration. The Company believes it mitigates these risks by continuing advocacy and collaboration with governing agencies and legislative bodies for continuing use of its modular products, staying abreast of technology trends in order to make good buy-sell decisions of electronic test equipment, and ongoing investment in repair and maintenance programs to ensure all types of rental equipment are maintained in good operating condition.

NOTE 2.

SIGNIFICANT ACCOUNTING POLICIES

Principles of Consolidation

The consolidated financial statements include the accounts of McGrath RentCorp and its 100% owned subsidiaries: Mobile Modular Management Corporation, Enviroplex Inc, TRS-RenTelco Inc. and Adler Tank Rentals, LLC. All intercompany accounts and transactions have been eliminated in consolidation.

Revenue Recognition

Rental revenue from operating leases is recognized on a straight-line basis over the term of the lease. Rental billings for periods extending beyond period end are recorded as deferred income and are recognized as earned. Rental related services revenue is primarily associated with relocatable modular building leases and consists of billings to customers for modifications, delivery, installation, building, additional site-related work, and dismantle and return delivery. Revenue from these services is an integral part of the negotiated lease agreement with customers and is recognized on a straight-line basis over the term of the lease. Revenues associated with liquid and solid containment solutions consists of billings for delivery, removal and cleaning of the tanks and boxes. These revenues are recognized in the period performed.

Sales revenue is recognized upon delivery and installation of the equipment to customers. Certain leases are accounted for as sales-type leases. For these leases, sales revenue and the related accounts receivable are recognized upon delivery and installation of the equipment and the unearned interest is recognized over the lease term on a basis which results in a constant rate of return on the unrecovered lease investment.

Other revenue is recognized when earned and primarily includes interest income on sales-type leases, rental income on facility rentals and certain logistics services.

Sales taxes charged to customers are reported on a net basis and are excluded from revenues and expenses.

Depreciation of Rental Equipment

Rental equipment is depreciated on a straight-line basis for financial reporting purposes and on an accelerated basis for income tax purposes. The costs of major refurbishment of relocatable modular buildings and portable storage containers are capitalized to the extent the refurbishment significantly adds value to, or extends the life of the equipment. Maintenance and repairs are expensed as incurred.

The estimated useful lives and residual values of the Company’s rental equipment used for financial reporting purposes are as follows:


Relocatable modular buildings		18 years, 50% residual value
Relocatable modular accessories		3 to 18 years, no residual value
Portable storage containers		25 years, 62.5% residual value
Electronic test equipment and accessories		1 to 8 years, no residual value
Liquid and solid containment tanks and boxes and accessories		10 to 20 years, no residual value

Costs of Rental Related Services

Costs of rental related services are primarily associated with relocatable modular building leases and consist of costs for services to be provided under the negotiated lease agreement for delivery, installation, modifications, skirting, additional site-related work, and dismantle and return delivery. Costs related to these services are recognized on a straight-line basis over the term of the lease. Costs of rental related services associated with liquid and solid containment solutions consists of costs of delivery, removal and cleaning of the tanks and boxes. These costs are recognized in the period the service is performed.

Impairment of Long-Lived Assets

The Company evaluates the carrying value of rental equipment and identifiable definite lived intangible assets for impairment whenever events or circumstances have occurred that would indicate the carrying amount may not be fully recoverable. A key element in determining the recoverability of long-lived assets is the Company’s outlook as to the future market conditions for its rental equipment. If the carrying amount is not fully recoverable, an impairment loss is recognized to reduce the carrying amount to fair value. The Company determines fair value based upon the condition of the rental equipment and the projected net cash flows from its rental and sale considering current market conditions. Goodwill and identifiable indefinite lived assets are evaluated for potential impairment annually or when circumstances indicate potential impairment. Impairment losses, if any, are determined based upon the estimated fair value of the asset. There were no impairments of long-lived assets during the years ended December 31, 2011, 2010 and 2009.

Other Direct Costs of Rental Operations

Other direct costs of rental operations include direct labor, supplies, repairs, insurance, property taxes, license fees and certain modular lease costs charged to customers in the negotiated rental rate, which are recognized on a straight-line basis over the term of the lease.

Cost of Sales

Cost of sales in the Consolidated Statements of Income includes the carrying value of the equipment sold and all direct costs associated with the sale.

Warranty Reserves

Sales of new relocatable modular buildings, portable storage containers, electronic test equipment and related accessories and liquid and solid containment tanks and boxes not manufactured by the Company are typically covered by warranties provided by the manufacturer of the products sold. The Company typically provides limited 90-day warranties for certain sales of used rental equipment and one-year warranties on equipment manufactured by Enviroplex. Although the Company’s policy is to provide reserves for warranties when required for specific circumstances, the Company has not found it necessary to establish such reserves to date as warranty costs have not been significant.

Property, Plant and Equipment

Property, plant and equipment are stated at cost, net of accumulated depreciation. Depreciation is recognized on a straight-line basis for financial reporting purposes, and on an accelerated basis for income tax purposes. Depreciation expense is included in “Selling and Administrative Expenses” in the Consolidated Statements of Income. Maintenance and repairs are expensed as incurred.

Property, plant and equipment consist of the following:


(dollar amounts in thousands)	Estimated Useful Life In Years		December 31,
(dollar amounts in thousands)	Estimated Useful Life In Years		2011			2010
Land		Indefinite	$	30,466		$	28,151

				94,019			77,462
Construction In Progress				683			6,399

				$94,702			$83,861

Construction in progress at December 31, 2011 consisted primarily of costs related to information technology projects. Construction in progress at December 31, 2010 consisted primarily of $3.7 million related to information technology projects and $2.4 million related to the expansion of the inventory center in Livermore, California.

Advertising Costs

Advertising costs are expensed as incurred. Total advertising expenses were $2.1 million, $1.7 million and $1.7 million for the years ended December 31, 2011, 2010 and 2009.

Income Taxes

Income taxes are accounted for using an asset and liability approach. Deferred tax assets and liabilities are recorded based on the differences between the financial statement and tax bases of assets and liabilities at the tax rates in effect when these differences are expected to reverse.

Goodwill and Intangible Assets

Purchase prices of acquired businesses have been allocated to the assets and liabilities acquired based on the 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 were allocated to goodwill and other intangible assets. Goodwill and intangible assets consists primarily of intangible assets of $39.9 million from the 2008 acquisition of Adler Tanks. Intangible assets related to customer relationships are amortized over eleven years. At December 31, 2011 and 2010, goodwill and trade name intangible assets which have indefinite lives totaled $33.4 million.

The Company assesses potential impairment of its goodwill and intangible assets when there is evidence that events or circumstances have occurred that would indicate the recovery of an asset’s carrying value is unlikely. The Company also assesses potential impairment of its goodwill and intangible assets on an annual basis regardless of whether there is evidence of impairment. If indicators of impairment were to be present in intangible assets used in operations and future discounted cash flows were not expected

to be sufficient to recover the assets’ carrying amount, an impairment loss would be charged to expense in the period identified. The amount of an impairment loss would be recognized as the excess of the asset’s carrying value over its fair value. Factors the Company considers important, which may cause impairment include, among others, significant changes in the manner of use of the acquired asset, negative industry or economic trends, and significant underperformance relative to historical or projected operating results.

The impairment review is performed by first assessing qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test. In the first step, the fair value of the reporting unit is compared to its carrying value to determine if the goodwill and intangible assets are impaired. If the fair value of the reporting unit exceeds the carrying value of the net assets assigned to that unit, then goodwill and intangible assets are not impaired and no further testing is required. If the carrying value of the net assets assigned to the reporting unit were to exceed its fair value, then the second step is performed in order to determine the implied fair value of the reporting unit’s goodwill and intangible assets and an impairment loss is recorded for an amount equal to the difference between the implied fair value and the carrying value of the goodwill and intangible assets.

The Company conducted its annual impairment analysis in the fourth quarter of its fiscal year. The impairment analysis did not result in an impairment charge for the fiscal years ended 2011, 2010 or 2009. Determining the fair value of a reporting unit is judgmental and involves the use of significant estimates and assumptions. The Company based its fair value estimates on assumptions that it believes are reasonable but are uncertain and subject to changes in market conditions.

Earnings Per Share

Basic earnings per share (“EPS”) is computed as net income divided by the weighted average number of shares of common stock outstanding for the period. Diluted EPS is computed as net income divided by the weighted average number of shares outstanding of common stock and common stock equivalents for the period including the dilutive effects of stock options and other potentially dilutive securities. Common stock equivalents result from the number of dilutive options computed using the treasury stock method and the average share price for the reported period. The table below presents the weighted-average common stock used to calculate basic and diluted earnings per share:


(in thousands)	Year Ended December 31,
	2011		2010		2009
Weighted-average common stock for calculating basic earnings per share		24,349		23,944		23,745
Effect of potentially dilutive securities from equity-based compensation		411		345		124

Weighted-average common stock for calculating diluted earnings per share		24,760		24,289		23,869

The following securities were not included in the computation of diluted earnings per share as their effect would have been anti-dilutive:

Accounts Receivable and Concentration of Credit Risk

The Company’s accounts receivable consist of amounts due from customers for rentals, sales, financed sales and unbilled amounts for the portion of Mobile Modular end-of-lease services earned, which were negotiated as part of the lease agreement. Unbilled receivables related to end-of-lease services, which consists of dismantle and return of buildings, were $17.2 million at December 31, 2011 and $17.0 million at December 31, 2010. The Company sells primarily on 30-day terms, individually performs credit evaluation procedures on its customers on each transaction and will require security deposits from its customers when a significant credit risk is identified. The Company records an allowance for doubtful accounts in amounts equal to the estimated losses expected to be incurred in the collection of the accounts receivable. The estimated losses are based on historical collection experience in conjunction with an evaluation of the current status of the existing accounts. Customer accounts are written off against the allowance for doubtful accounts when an account is determined to be uncollectable. The allowance for doubtful accounts activity was as follows:


(in thousands)	2011			2010
Beginning Balance, January 1	$	1,700		$	1,700
Provision for doubtful accounts		1,755			1,494
Write-offs, net of recoveries		(1,955	)		(1,494	)

Ending Balance, December 31	$	1,500		$	1,700

Financial instruments that potentially subject the Company to concentration of credit risk consist primarily of trade accounts receivable. From time to time, the Company maintains cash balances in excess of the Federal Deposits Insurance limits.

Fair Value of Financial Instruments

The Company believes that the carrying amounts for cash, accounts receivable, accounts payable and notes payable approximate their fair values except for fixed rate debt included in notes payable which has an estimated fair value of $107.0 million and $12.2 million compared to the recorded value of $100.0 million and $12.0 million as of December 31, 2011 and 2010, respectively. The estimates of fair value of the Company’s fixed rate debt are based on the borrowing rates currently available to the Company for bank loans with similar terms and average maturities.

Foreign Currency Transactions

The Company’s Canadian subsidiary, TRS-RenTelco Inc., a British Columbia corporation, functions as a branch sales office for TRS-RenTelco in Canada. Foreign currency transaction gains and losses of the Company’s Canadian subsidiary are reported in the results of operations in the period in which they occur. Currently, the Company does not use derivative instruments to hedge its economic exposure with respect to assets, liabilities and firm commitments as the foreign currency transactions and risks to date have not been significant.

Stock-Based Compensation

The Company measures stock-based compensation expense based on grant date fair value and recognizes that expense in earnings over the service period of each award. The Company utilizes the Black-Scholes option-pricing model to estimate the fair value of employee stock-based compensation at the date of grant, which requires the use of accounting judgment and financial estimates, including estimates of the expected term option holders will retain their vested stock options before exercising them, the estimated volatility of the Company’s stock price over the expected term and the expected number of options that will be forfeited prior to the completion of their vesting requirements. Application of alternative assumptions could produce significantly different estimates of the fair value of stock-based compensation amounts recognized in the Consolidated Statements of Income.

MCGRATH RENTCORP

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

For the years ended December 31, 2011, 2010 and 2009, the non-cash stock-based compensation expense included in Selling and Administrative Expenses in the Consolidated Statements of Income was $5.2 million, $4.2 million and $3.6 million, before provision for income taxes, respectively. The Company recorded a tax benefit of approximately $2.0 million, $1.6 million and $1.4 million related to the aforementioned stock-based compensation expenses. For the years ended December 31, 2011, 2010 and 2009, the stock-based compensation expenses, net of taxes, reduced net income by $3.2 million, $2.6 million and $2.2 million, respectively or $0.13, $0.11, and $0.09 per diluted share for each period, respectively.

The fair value of each option granted was estimated on the date of grant using the Black-Scholes option-pricing model using the following weighted average assumptions:


	Year Ended December 31,
	2011			2010			2009
Expected term (in years)		5.0			5.2			5.0
Expected volatility		51.6	%		51.2	%		45.2	%
Expected dividend yields		3.4	%		3.8	%		5.6	%
Risk-free interest rates		2.0	%		2.2	%		2.0	%

The Company monitors option exercise behavior to determine the appropriate homogenous groups for estimation purposes. Currently, the Company’s option activity is separated into two categories: directors and employees. The expected term of the options represents the estimated period of time until exercised and is based on historical experience, giving consideration to the option terms, vesting schedules and expectations of future employee behavior. Expected stock volatility is based on historical stock price volatility of the Company and the risk-free interest rates are based on U.S. Treasury yields in effect on the date of the option grant for the estimated period the options will be outstanding. The expected dividend yield is based upon the current dividend annualized as a percentage of the grant exercise price.

The weighted average grant date fair value per share was $9.68, $8.12 and $3.91 during the years ended 2011, 2010 and 2009, respectively.

Use of Estimates

The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions in determining reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during each period presented. Actual results could differ from those estimates. The most significant estimates included in the financial statements are the future cash flows and fair values used to determine the recoverability of the rental equipment and identifiable definite lived intangible assets carrying value, the various assets’ useful lives and residual values, and the allowance for doubtful accounts.

Reclassifications

In order to conform to current year presentation, certain amounts were reclassified from Selling and Administrative expenses to Other Revenues. This reclassification had no impact on net income, earnings per share or operating cash flows.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

In 2011, 2010 and 2009 the Company obtained an excess tax benefit of $1.0 million, $1.0 million and $0.4 million respectively, from the exercise of non-qualified stock options and early dispositions of stock obtained through the exercise of incentive stock options by employees. The tax benefit was recorded as common stock in conjunction with the proceeds received from the exercise of the stock options.

As of December 31, 2011, the Company’s federal net operating losses for tax return purposes were $59.9 million. If not utilized, these carry forwards will begin to expire in 2030. As of December 31, 2011, the Company had state and foreign tax credit carry forwards of $4.6 million, which will begin to expire in 2010, if not utilized.

The Company recognizes the financial statement benefit of a tax position only after determining that the relevant tax authority would more likely than not sustain the position following an audit. For tax positions meeting the more-likely-than-not threshold, the amount recognized in the financial statements is the largest benefit that has a greater than 50 percent likelihood of being realized upon ultimate settlement with the relevant tax authority. The Company evaluated all of its tax positions for which the statute of limitations remained open and determined there were no material unrecognized tax benefits as of December 31, 2011 and 2010. In addition, there have been no material changes in unrecognized benefits during 2011, 2010 and 2009.

The Company is subject to income taxes in the U.S. federal jurisdiction, and various states and foreign jurisdictions. Tax regulations within each jurisdiction are subject to interpretation of the related tax laws and regulations and require the application of significant judgment. With few exceptions, the Company is no longer subject to U.S. federal, state and local, or non-U.S. income tax examinations by tax authorities for the years before 2007.

Our income tax returns are subject to examination by federal, state and foreign tax authorities. We are currently under examination by the California Franchise Tax Board for the 2007 and 2008 tax years. 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.

The Company recognizes interest and penalties related to unrecognized tax benefits in the provision for income taxes for all periods presented. Such interest and penalties were not significant for the years ended December 31, 2011, 2010 and 2009.

BENEFIT PLANS

Stock Plans

The Company adopted the 2007 Stock Incentive Plan (the “2007 Plan”) effective June 6, 2007, under which 1,875,000 shares of common stock of the Company, plus the number of shares that remained available for grants of awards under the Company’s 1998 Stock Option Plan (the “1998 Plan”) and those shares that become available as a result of forfeiture, termination, or expiration of awards previously granted under the 1998 Plan, were reserved for the grant of awards to its employees, directors and consultants to acquire common stock of the Company. The 2007 Plan provides for the grant of awards in the form of stock options, stock appreciation rights, restricted stock, restricted stock units or other rights and benefits. Options under the 2007 Plan are granted at an exercise price of not less than 100% of the fair market value of the Company’s common stock on the date of grant. The 2007 Plan replaced the Company’s 1998 Plan and the 2000 Long-Term Bonus Plan.

Stock Options

As of December 31, 2011, a cumulative total of 6,296,100 shares subject to options have been granted with exercise prices ranging from $11.26 to $34.28. Of these, options have been exercised for the purchase of 2,406,347 shares, while options for 803,734 shares have been terminated, and options for 3,086,019 shares remain outstanding under the stock plans. Most of these options vest over five years and expire seven and ten years after grant. To date, no options have been issued to any of McGrath RentCorp’s non-employee advisors. As of December 31, 2011, 547,834 shares remain available for issuance of awards under the stock plans.

The intrinsic value of stock options at any point in time is calculated as the difference between the exercise price of the underlying awards and the quoted price of the Company’s common stock. The aggregate intrinsic value of options outstanding as of December 31, 2011 and 2010 was $16.9 million and $11.4 million, respectively, and had a weighted average remaining contract life of 3.52 years and 4.33 years, respectively. The intrinsic value for options exercisable as of December 31, 2011 and 2010 was $10.5 million and $5.0 million, respectively, and had a weighted average remaining contract life of 3.22 years and 4.10 years, respectively. The aggregate intrinsic value of options exercised and sold under the Company’s stock option plans was $3.7 million, $3.6 million and $0.6 million for the years ended December 31, 2011, 2010 and 2009, respectively, determined as of the date of option exercise. As of December 31, 2011, there was approximately $4.6 million of total unrecognized compensation cost related to unvested share-based compensation option arrangements granted under the Company’s stock plans, which is expected to be recognized over a weighted-average period of 1.30 years.

Employee Stock Ownership Plan

In 1985, the Company established a non-leveraged Employee Stock Ownership Plan (“Plan”). Under the terms of the Plan, as amended, the Company makes annual contributions in the form of cash or common stock of McGrath RentCorp to a trust for the benefit of eligible employees. Employees of the Company are generally eligible to participate in the Plan on the January 1^st, or July 1^st, immediately following the completion of the minimum of 1,000 hours and twelve months of service. The amount of the contribution is determined annually by the Board of Directors. There was no contribution approved in 2011, 2010 or 2009. Contributions to the Plan are allocated to participants following a formula based upon years of service and covered compensation. Dividends paid to Plan participants are treated as ordinary dividends and, in accordance with existing tax laws, are deducted by the Company in the year paid. For the years ended December 31, 2011, 2010 and 2009, dividends deducted by the Company were $0.4 million, $0.5 million and $0.5 million, respectively, which resulted in a tax benefit of approximately $0.2 million each year. Plan shares outstanding at December 31, 2011 were 448,742, or 2% of total common shares outstanding, and are included in basic and diluted earnings per share calculations.

401(k) Plans

In 1995, McGrath RentCorp established a contributory retirement plan, the McGrath RentCorp 401(k) Plan, as amended, covering eligible employees of McGrath RentCorp with at least three months of service. The McGrath RentCorp 401(k) Plan provides that each participant may annually contribute an elected percentage of his or her salary, not to exceed the statutory limit. McGrath RentCorp, at its discretion, may make contributions. Contributions are expensed in the year approved by the Board of Directors. There was $1.1 million expensed in 2011, zero in 2010 and $0.9 million in 2009.

In 1997, Enviroplex established a contributory retirement plan, the Enviroplex 401(k) Plan, as amended, covering eligible employees of Enviroplex with at least three months of service. The Enviroplex 401(k) Plan provides that each participant may annually contribute an elected percentage of his or her salary, not to exceed the statutory limit. Enviroplex at its discretion may make a matching contribution. Enviroplex made contributions of $35,000 and $43,000 in 2011 and 2009, respectively. There was no matching contribution in 2010.

SEGMENT REPORTING

FASB guidelines establish annual and interim reporting standards for an enterprise’s operating segments and related disclosures about its products, services, geographic areas and major customers. In accordance with these guidelines the Company’s four reportable segments are Mobile Modular, TRS-RenTelco, Adler Tanks and Enviroplex. Management focuses on several key measures to evaluate and assess each segment’s performance including rental revenue growth, gross margin, and income before provision for income taxes. As separate corporate entities, Adler Tanks and Enviroplex revenues and expenses are separately maintained from Mobile Modular and TRS-RenTelco. Excluding interest expense, allocations of revenue and expense not directly associated with one of these segments are generally allocated to Mobile Modular, TRS-RenTelco and Adler Tanks, based on their pro-rata share of direct revenues. Interest expense is allocated amongst Mobile Modular, TRS-RenTelco and Adler Tanks based on their pro-rata share of average rental equipment at cost, goodwill, intangible assets, accounts receivable, deferred income and customer security deposits. The Company does not report total assets by business segment. Summarized financial information for the years ended December 31, 2011, 2010 and 2009, for the Company’s reportable segments is shown in the following table:

Gross Enviroplex sales revenues were $20,884, $12,321 and $8,106 in 2010, 2009 and 2008, respectively, which includes inter-segment sales to Mobile Modular of $97, $626 and $687, which have been eliminated in consolidation.

Utilization is calculated each month by dividing the cost of rental equipment on rent by the total cost of rental equipment excluding new equipment inventory and accessory equipment. The average utilization for the period is calculated using the average costs of rental equipment.

No single customer accounted for more than 10% of total revenues during 2011, 2010 and 2009. In addition, total foreign country customers and operations accounted for less than 10% of the Company’s revenues and long-lived assets for the same periods.

ITEM 9A.

CONTROLS AND PROCEDURES.

Evaluation of Disclosure Controls and Procedures. The Company’s Management under the supervision and with the participation of the Company’s Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”) are responsible for establishing and maintaining “disclosure controls and procedures” (as defined in rules promulgated under the Securities Exchange Act of 1934, as amended) for the Company. Based on their evaluation the CEO and CFO have concluded that the Company’s disclosure controls and procedures were effective as of December 31, 2011.

Changes in Internal Control over Financial Reporting. During the last quarter of the Company’s fiscal year ended December 31, 2011, the Company converted to a new financial system, Oracle EBS, to help manage our business, to process transactions, and to record financial activity. We have adapted our processes and procedures to reflect our use of this new financial system which is an integral element of our internal control over financial reporting. Based on the evaluation described above, our Chief Executive Officer and Chief Financial Officer concluded that there has not been any change in our internal control over financial reporting during the three months ended December 31, 2011 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Limitations on the Effectiveness of Controls. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues, if any, within a company have been detected. The Company’s disclosure controls and procedures are designed to provide reasonable assurance of achieving their objectives, and the CEO and CFO have concluded that these controls and procedures are effective at the “reasonable assurance” level.

Management’s Assessment of Internal Control. Management’s assessment of the effectiveness of the Company’s internal control over financial reporting as of December 31, 2011, is discussed in the Management’s Report on Internal Control Over Financial Reporting included on page 57.

The effectiveness of the Company’s internal control over financial reporting as of December 31, 2011 has been audited by Grant Thornton LLP, the Company’s independent registered public accounting firm, and its report is included in this Annual Report on Form 10-K.
