PART I

Cautionary Statement About Forward-Looking Statements

This report includes certain “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Statements in the future tense, and all statements accompanied by terms such as “believe,” “project,” “expect,” “estimate,” “assume,” “intend,” “anticipate,” “target,” “plan,” and variations thereof and similar terms are intended to be forward-looking statements. We intend that all forward-looking statements we make will be subject to safe harbor protection of the federal securities laws pursuant to Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934.

Our disclosure and analysis in this report, in our Annual Report to Shareholders and in our other filings with the Securities and Exchange Commission (“SEC”) contain forward-looking statements regarding our intent, belief and current expectations about our strategic direction, prospects and future results. From time to time, we also provide forward-looking statements in other materials we release as well as oral forward-looking statements. Such statements give our current expectations or forecasts of future events; they do not relate strictly to historical or current facts. Management believes that these forward-looking statements are reasonable as and when made. However, caution should be taken not to place undue reliance on any such forward-looking statements because such statements speak only as of the date when made.

Forward-looking statements are subject to certain risks and uncertainties that could cause actual results to differ materially from our historical experience and our present expectations or anticipated results. These risks and uncertainties are described in Part I, “Item 1A. Risk Factors” and may also be described from time to time in our future reports filed with the SEC. You should consider the limitations on, and risks associated with, forward-looking statements and not unduly rely on the accuracy of predictions contained in such forward-looking statements. We do not undertake any obligation to update forward-looking statements to reflect events, circumstances, changes in expectations, or the occurrence of unanticipated events after the date of those statements.

Overview

United Parcel Service, Inc. (“UPS”) was founded in 1907 as a private messenger and delivery service in Seattle, Washington. Today, UPS is the world’s largest package delivery company, a leader in the U.S. less-than-truckload industry and the premier provider of global supply chain management solutions. We deliver packages each business day for 1.1 million shipping customers to 7.7 million consignees in over 220 countries and territories. In 2011, we delivered an average of 15.8 million pieces per day worldwide, or a total of 4.01 billion packages. Total revenue in 2011 was $53.1 billion.

We are a global leader in logistics, and we create value for our customers through solutions that lower costs, improve service and provide highly customizable supply chain control and visibility. Customers are attracted to our broad set of services that are delivered as promised through our integrated ground, air and ocean global network.

Our services and integrated network allow shippers to simplify their supply chains by using fewer carriers and to adapt their transportation requirements and spend as their businesses evolve. Across our service portfolio, we also provide control and visibility of customers’ inventories and supply chains via our UPS technology platform. The information flow from UPS technology drives improvements for our customers, as well as for UPS, in reliability, flexibility, productivity and efficiency.

Particularly over the last decade, UPS has significantly expanded the scope of our capabilities to include more than package delivery. Our logistics and distribution capabilities give companies the power to easily expand their businesses to new markets around the world. By leveraging our international infrastructure, UPS

enables our customers to bridge time zones, cultures, distances and languages to keep the entire supply chain moving smoothly. We operate approximately 800 logistics facilities, in more than 120 countries, offering warehouse space of 35 million square feet.

We serve the global market for logistics services, which include transportation, distribution, forwarding, ground, ocean and air freight, brokerage and financing. Our technology seamlessly binds our service portfolio. We have three reportable segments: U.S. Domestic Package, International Package and Supply Chain & Freight, all of which are described below. For financial information concerning our reportable segments and geographic regions, refer to note 12 of our consolidated financial statements.

Business Strategy

Customers leverage our broad array of services; balanced global presence in North America, Europe, Asia and Latin America; reliability; and industry leading technology for competitive advantage in markets where they choose to compete. We prudently invest to expand our integrated network and our service portfolio. Technology investments create user-friendly shipping, e-commerce, logistics management and visibility tools for our customers, while supporting UPS’s ongoing efforts to increase operational efficiencies.

Our service portfolio and investments are rewarded with among the best returns on invested capital and operating margins in the industry. We have a long history of sound financial management. Our balance sheet reflects financial strength that few companies can match. As of December 31, 2011, we had a balance of cash and marketable securities of approximately $4.275 billion and shareowners’ equity of $7.108 billion. Our Moody’s and Standard & Poor’s short-term credit ratings are P-1 and A-1+, respectively, and our Moody’s and Standard & Poor’s long-term credit ratings are Aa3 and AA-, respectively. We have a stable outlook from both of these credit rating agencies. Cash generation is a significant strength of UPS. This gives us strong capacity to service our obligations and allows for distributions to shareowners, reinvestment in our businesses and the pursuit of growth opportunities.

We enable and are the beneficiaries of the following trends:

Expansion of Global Trade

Trade across borders is predicted to grow at rates that are at least double the growth rates of U.S. and global domestic production for the foreseeable future. As a result, U.S. and international economies are becoming more inter-connected and dependent on foreign trade.

UPS plays an important role in global trade and is uniquely positioned to take advantage of trade growth, wherever it emerges. Our balanced global presence and productivity enhancing technologies allow customers to effortlessly expand to new markets. We advocate the expansion of free trade, including the passage of regional trade pacts and the removal of trade barriers. Free trade is a catalyst for job creation, economic growth and improved living standards; additionally, it propels our growth.

Emerging Market Growth

As our current and prospective customers seek growth outside of developed markets, they look to emerging markets for expansion. We make long-term, measured investments in markets where our customers choose to grow. Our investments are scaled to the local opportunity. We typically follow a pattern of entering a market through importing and exporting, expanding domestically with a partner or alliance, and then ultimately acquiring domestic operations where we see value and return. China is a prime example of this strategy as we continue to clear hurdles that will enable us to realize this vision. Our two key air hubs in Shanghai and Shenzhen support market expansion through increased cargo capacity and faster intra-Asia transit times, while enabling our customers to ship later in the day. We link Asia to Europe with overnight flights from Hong Kong through our air hub in Cologne, Germany.

Taken together, these two trends (expanding global trade and emerging market growth) underscore why our international business is a catalyst for UPS’s growth.

Increasing need for vertical expertise in the integrated carrier space

We provide repeatable, scalable sector solutions for our customers. We invest in global capabilities and create value propositions for certain industries where there is a fit between our customers’ needs and our offerings. Segments where we bring unique value propositions include health care, high-tech, automotive & industrial manufacturing, retail, government and professional services.

The health care industry faces complex challenges, including the continuing expiration of drug patents and the shifting landscape of regulatory requirements and drug pricing controls that differ by country. To counter these threats, many pharmaceutical companies have embarked on global expansion strategies that require infrastructure. UPS has aligned our resources to serve these needs through a well-developed supply chain management capability that is designed to satisfy regulatory and compliance requirements. We have built 33 dedicated health care facilities with over 5 million square feet of distribution space. These facilities allow us to provide reliable, secure, cost-effective warehousing and distribution for pharmaceutical firms’ supply chains, which, in turn, allow them to easily navigate across and within borders.

We will continue to expand our vertical offerings, growing not only our physical and market footprint, but also our expertise and technology to support industry specific needs. Our growth strategy is to increase the number of customers benefitting from these vertical solutions and gain their associated small package and freight transportation.

Outsourcing

Outsourcing supply chain management is becoming more prevalent, as customers increasingly view professional management and operation of their supply chains as a strategic advantage. This trend enables companies to focus on what they do best. We can meet our customers’ needs for outsourced logistics with our global capabilities in customized forwarding, warehousing, distribution, delivery and post-sales services. As we move deeper into customers’ supply chains, we do so with a shared vision on how to best serve those who rely on our customers. We integrate our technology for efficiencies, visibility and control to ensure that we execute as promised.

Retail e-Commerce Growth

Throughout much of the world, e-commerce growth continues to outpace traditional lines of business. We continue to create new services, supported by UPS technology, that complement the traditional UPS premium home delivery service to address the needs of e-commerce shippers and receivers (“consignees”). Our offerings span a broad spectrum from cost-sensitive solutions such as SurePost, for shipments where economy takes precedence over speed, up to feature-rich solutions, including our new UPS My Choice service that provides consignees with revolutionary visibility and control of their inbound shipments.

With UPS My Choice, consignees direct the timing and location of their deliveries before a delivery attempt is made. Premium features include online delivery planners, detailed driver instructions, alternate delivery locations and a two-hour delivery window. Delivery alerts come via the channel chosen by the consignee—email, SMS text, etc. We strive to give our customers that ship using UPS My Choice the best delivery experience in the industry—delivery on the first attempt, where and when their customers want it.

Technology

Technology powers logistics. We bring industry leading UPS technology to our customers who, in turn, realize increased productivity, greater control of their supply chains and improved customer experience when they integrate with our technology. Customers benefit through offerings such as:

Technology, coupled with high-quality UPS employees, forms the foundation of our reliability and allows us to take customer experience to a higher level. Technology delivers value to our customers and returns to our shareholders. Recent advancements that evidence further gains in UPS’s operational efficiency, flexibility, reliability and customer experience include:

Reporting Segments and Products & Services

As a global leader in logistics, UPS offers a broad range of domestic and export delivery services; the facilitation of international trade; and the deployment of advanced technology to more efficiently manage the world of business. We seek to streamline our customers’ shipment processing and integrate critical transportation information into their own business processes, helping them to create supply chain efficiencies, better serve their customers and improve their cash flows.

Global Small Package

UPS’s global small package operations provide time-definite delivery services for express letters, documents and small packages via air and ground services. We provide domestic delivery services within 56 countries and export services to more than 220 countries and territories around the world. We handle packages that weigh up to 150 pounds and are up to 165 inches in combined length and girth. All of our package services are supported by numerous shipping, visibility and billing technologies.

UPS handles all levels of service (air, ground, domestic, international, commercial, residential) through one global integrated pickup and delivery network. All packages are commingled throughout their journey in our network, except when necessary to meet their specific service commitments. This enables one UPS driver to pick up our customers’ shipments, for any of our services, at the same scheduled time, day after day. Compared to companies with single service network designs, our integrated network uniquely provides operational and capital efficiencies while being easier on the environment.

Upon request, we offer same-day pickup of air and ground packages. Based on their needs, customers can schedule pickups for one to five days a week. Additionally, we provide our customers with easy access to UPS, with over 150,000 domestic and international entry points including: 40,000 drop boxes, 1,000 customer centers, 4,700 independently owned and operated locations of The UPS Store worldwide, 13,000 authorized shipping outlets and commercial counters, 6,300 alliance locations and 86,300 UPS drivers who can accept packages provided to them.

With the growth of online shopping, our customers’ needs for efficient and reliable returns have increased. To this end, we have developed a robust selection of returns services that are available in over 100 countries. Options vary based on customer needs and country, and range from cost-effective solutions such as UPS Returns, which simply enables shippers to provide their customers with a return shipping label, to services as specialized as UPS Returns Exchange. In this new service, the UPS driver simplifies product exchanges by delivering a replacement item and picking up a return item in the same stop, and assisting with the re-packaging process.

We operate a global ground fleet of approximately 101,000 vehicles, of which our U.S. ground fleet serves all business and residential zip codes in the contiguous U.S. We operate a global air fleet of 523 aircraft, and we are one of the largest airlines in the world. Our global air network is centered at our Worldport hub in Louisville, Kentucky. Worldport sort capacity, currently at 416,000 packages per hour, has expanded over the years due to volume growth and a centralization effort. This facility is supplemented by our regional U.S. air hubs in Hartford, Connecticut; Ontario, California; Philadelphia, Pennsylvania; and Rockford, Illinois. This network design allows for cost-effective package processing in our most technology-enabled facility while enabling us to use fewer, larger and more fuel-efficient aircraft. Our largest international air hub is in Cologne, Germany, with other regional international hubs in Miami, Florida; Canada; Hong Kong; Singapore; Taiwan; and China.

U.S. Domestic Package Reporting Segment

UPS is a leader in time-definite, money-back guaranteed, small package delivery services. We offer a full spectrum of U.S. domestic guaranteed ground and air package transportation services. Depending on the delivery speed needed, customers can select from a range of guaranteed time and day definite delivery options.

Table of Contents

International Package Reporting Segment

Our International Package reporting segment includes the small package operations in Europe, Asia, Canada and Latin America. UPS offers a wide selection of guaranteed, day and time-definite international shipping services.

Europe, our largest region outside of the U.S., accounts for roughly half of international revenue and is one of our growth engines. Factors contributing to this are the highly fragmented nature of the market and the fact that exports make up a significant part of Europe’s GDP. Given our well-known, trusted brand and distinctive integrated network, we believe there is continued strong potential for growth in small package exports in Germany, the U.K., France, Italy, Spain and the Netherlands. Due to our strong growth, we are expanding our main European air hub in Cologne by 70% to a capacity of 190,000 packages per hour. Expansion will come in stages; the first stage was completed in the fourth quarter of 2011 with the final stage targeted for 2013.

Asia is another growth engine due to attractive growth rates in intra-Asian trade and the dynamic Chinese economy. We are bringing faster time-in-transit to customers focused on intra-Asian trade, reducing transit days from Asia to Europe, and continuing to build our China presence. Our recent China investments include:

We serve more than 40 Asia-Pacific countries and territories through more than two dozen alliances with local delivery companies that supplement company-owned operations. In Vietnam, our volume has doubled since entering into an alliance with a local partner in 2010.

Additional International highlights include the following:

Supply Chain & Freight Reporting Segment

The Supply Chain & Freight segment consists of our forwarding and logistics services, our UPS Freight business, and our financial offerings through UPS Capital. We manage supply chains in over 195 countries and territories, with approximately 35 million square feet of distribution space worldwide. Supply chain complexity creates demand for a global service offering that incorporates transportation, distribution and international trade and brokerage services, with financial and information services. We meet this demand by offering a broad array of services, which are described below.

The 2011 acquisition of Italy-based Pieffe Group (“Pieffe”) supports our global health care strategy, which has seen us make investments to better serve our growing customer base in the pharmaceutical, biotech and medical device industries. Previously family-owned, Pieffe is a pharmaceutical logistics business with more than 35 years of experience offering high-quality storage, distribution and cold chain solutions to some of the world’s leading pharmaceutical brands.

Freight Forwarding

UPS is the second largest U.S. domestic air freight carrier and among the top six international air freight forwarders globally. UPS offers a portfolio of guaranteed and non-guaranteed global air freight services. Additionally, as one of the world’s leading non-vessel operating common carriers, UPS also provides ocean freight full-container load and less-than container load shipments between most major ports around the world.

Customs Brokerage

UPS is among the world’s largest customs brokers by both the number of shipments processed annually and by the number of dedicated brokerage employees worldwide. With decades of customs brokerage experience, we provide our customers with customs clearance, trade management and international trade consulting services.

Community

We believe that strong communities are vital to the success of our company. By combining our philanthropy with the volunteer time and talents of our employees, UPS helps drive positive change for organizations and communities in need across the globe. The highlights of our corporate citizenship efforts in 2011 include:

Reputation

Many of our customers trust UPS to extend their brand. We were pleased that UPS earned the top rating in our industry on the American Customer Satisfaction Index in 2011. As noted in Millward Brown’s and Interbrand’s top brand rankings, we have one of the most valuable brands in the world. UPS also has been named to industry leading positions in Fortune Magazine’s Most Admired and Harris Interactive’s Reputation Quotient surveys.

Employees

The strength of our company is our people, working together with a common purpose. We had approximately 398,000 employees as of December 31, 2011, of which 323,000 are in the U.S. and 75,000 are located internationally. Our global workforce includes approximately 71,000 management employees (36% of whom are part-time) and 327,000 hourly employees (46% of whom are part-time).

As of December 31, 2011, we had approximately 245,000 employees employed under a national master agreement and various supplemental agreements with local unions affiliated with the International Brotherhood of Teamsters (“Teamsters”). These agreements run through July 31, 2013.

We have approximately 2,700 pilots who are employed under a collective bargaining agreement with the Independent Pilots Association (“IPA”), which became amendable at the end of 2011.

Our airline mechanics are covered by a collective bargaining agreement with Teamsters Local 2727, which runs through November 1, 2013. In addition, approximately 3,200 of our ground mechanics who are not employed under agreements with the Teamsters are employed under collective bargaining agreements with the International Association of Machinists and Aerospace Workers (“IAM”). Our agreement with the IAM runs through July 31, 2014.

The experience of our management team continues to be an organizational strength. Nearly 40% of our full-time managers have more than 20 years of service with UPS.

Table of Contents

We believe that our relations with our employees are good. We periodically survey all our employees to determine their level of job satisfaction. Areas of concern receive management attention as we strive to keep UPS the employer of choice among our employees. We consistently receive numerous awards and wide recognition as an employer-of-choice, resulting in part from our emphasis on diversity and corporate citizenship.

Safety

We promote safety throughout our operations. Our Automotive Fleet Safety Program is built with the following components:

Our workplace safety program is built upon a comprehensive health and safety process. The foundation of this process is our employee-management health and safety committees. The workplace safety process focuses on employee conditioning and safety-related habits. Our employee co-chaired health and safety committees complete comprehensive facility audits and injury analyses, and recommend facility and work process changes.

Competition

We are the largest package delivery company in the world, in terms of both revenue and volume. We offer a broad array of services in the package and freight delivery industry and, therefore, compete with many different local, regional, national and international companies. Our competitors include worldwide postal services, various motor carriers, express companies, freight forwarders, air couriers and others. Through our supply chain service offerings, we compete with a number of participants in the supply chain, financial services and information technology industries.

Competitive Strengths

Our competitive strengths include:

Integrated Global Network.    We believe that our integrated global ground and air network is the most extensive in the industry. We handle all levels of service (air, ground, domestic, international, commercial, residential) through a single pickup and delivery service network.

Our sophisticated engineering systems allow us to optimize our network efficiency and asset utilization on a daily basis. This unique, integrated global business model creates consistent and superior returns.

10

Table of Contents

We believe we have the most comprehensive integrated delivery and information services portfolio of any carrier in Europe. In other regions of the world, we rely on both our own and local service providers’ capabilities to meet our service commitments.

Global Presence.    UPS serves more than 220 countries and territories around the world. We have a presence in all of the world’s major economies.

Leading-edge Technology.    We are a global leader in developing technology that helps our customers optimize their shipping and logistics business processes to lower costs, improve service and increase efficiency.

Technology powers virtually every service we offer and every operation we perform. Our technology offerings are initiated by our customers’ needs. We offer a variety of on-line service options that enable our customers to integrate UPS functionality into their own businesses not only to conveniently send, manage and track their shipments, but also to provide their customers with better information services. We provide the infrastructure for an Internet presence that extends to tens of thousands of customers who have integrated UPS tools directly into their own web sites.

Broad Portfolio of Services.    Our portfolio of services enables customers to choose the delivery option that is most appropriate for their requirements. Increasingly, our customers benefit from business solutions that integrate many UPS services in addition to package delivery. For example, our supply chain services—such as freight forwarding, customs brokerage, order fulfillment, and returns management—help improve the efficiency of the supply chain management process.

Customer Relationships.    We focus on building and maintaining long-term customer relationships. We serve 1.1 million pick-up customers and 7.7 million delivery customers daily. Cross-selling small package, supply chain and freight services across our customer base is an important growth mechanism for UPS.

Brand Equity.    We have built a leading and trusted brand that stands for quality service, reliability and product innovation. The distinctive appearance of our vehicles and the friendliness and helpfulness of our drivers are major contributors to our brand equity.

Distinctive Culture.    We believe that the dedication of our employees results in large part from our distinctive “employee-owner” concept. Our employee stock ownership tradition dates from 1927, when our founders, who believed that employee stock ownership was a vital foundation for successful business, first offered stock to employees. To facilitate employee stock ownership, we maintain several stock-based compensation programs.

Our long-standing policy of “promotion from within” complements our tradition of employee ownership, and this policy reduces the need for us to hire managers and executive officers from outside UPS. The majority of our management team began their careers as full-time or part-time hourly UPS employees, and have spent their entire careers with us. Many of our executive officers have more than 30 years of service with UPS and have accumulated a meaningful ownership stake in our company. Therefore, our executive officers have a strong incentive to effectively manage UPS, which benefits all our shareowners.

Financial Strength.    Our balance sheet reflects financial strength that few companies can match. Our financial strength gives us the resources to achieve global scale; to invest in employee development, technology, transportation equipment and buildings; to pursue strategic opportunities that facilitate our growth; to service our obligations; and to return value to our shareowners in the form of dividends and share repurchases.

Government Regulation

Air Operations

The U.S. Department of Transportation (“DOT”), the Federal Aviation Administration (“FAA”), and the U.S. Department of Homeland Security, through the Transportation Security Administration (“TSA”), have

11

Table of Contents

regulatory authority over United Parcel Service Co.’s (“UPS Airlines’”) air transportation services. The Federal Aviation Act of 1958, as amended, is the statutory basis for DOT and FAA authority and the Aviation and Transportation Security Act of 2001, as amended, is the basis for TSA aviation security authority.

The DOT’s authority primarily relates to economic aspects of air transportation, such as discriminatory pricing, non-competitive practices, interlocking relations and cooperative agreements. The DOT also regulates, subject to the authority of the President of the United States, international routes, fares, rates and practices, and is authorized to investigate and take action against discriminatory treatment of U.S. air carriers abroad. International operating rights for U.S. airlines are usually subject to bilateral agreement between the U.S. and foreign governments. UPS Airlines has international route operating rights granted by the DOT and we may apply for additional authorities when those operating rights are available and are required for the efficient operation of our international network. The efficiency and flexibility of our international air transportation network is dependent on DOT and foreign government regulations and operating restrictions.

The FAA’s authority primarily relates to safety aspects of air transportation, including aircraft operating procedures, transportation of hazardous materials, record keeping standards and maintenance activities, personnel and ground facilities. In 1988, the FAA granted us an operating certificate, which remains in effect so long as we meet the safety and operational requirements of the applicable FAA regulations. In addition, we are subject to non-U.S. government regulation of aviation rights involving non-U.S. jurisdictions, and non-U.S. customs regulation.

FAA regulations mandate an aircraft corrosion control program, along with aircraft inspection and repair at periodic intervals specified by approved programs and procedures, for all aircraft. Our total expenditures under these programs for 2011 were not material. The future cost of repairs pursuant to these programs may fluctuate according to aircraft condition, age and the enactment of additional FAA regulatory requirements.

The TSA regulates various security aspects of air cargo transportation in a manner consistent with the TSA mission statement to “protect the Nation’s transportation systems to ensure freedom of movement for people and commerce.” UPS Airlines, and specified airport and off airport locations, are regulated under TSA regulations applicable to the transportation of cargo in an air network. In addition, personnel, facilities and procedures involved in air cargo transportation must comply with TSA regulations.

UPS Airlines, along with a number of other domestic airlines, participates in the Civil Reserve Air Fleet (“CRAF”) program. Our participation in the CRAF program allows the U.S. Department of Defense (“DOD”) to requisition specified UPS Airlines wide-body aircraft for military use during a national defense emergency. The DOD compensates us for the use of aircraft under the CRAF program. In addition, participation in CRAF entitles UPS Airlines to bid for military cargo charter operations.

Ground Operations

Our ground transportation of packages in the U.S. is subject to the DOT’s jurisdiction with respect to the regulation of routes and to both the DOT’s and the states’ jurisdiction with respect to the regulation of safety, insurance and hazardous materials. We are subject to similar regulation in many non-U.S. jurisdictions.

The Postal Reorganization Act of 1970 created the U.S. Postal Service as an independent establishment of the executive branch of the federal government, and created the Postal Rate Commission, an independent agency, to recommend postal rates. The Postal Accountability and Enhancement Act of 2006 amended the 1970 Act to give the re-named Postal Regulatory Commission revised oversight authority over many aspects of the Postal Service, including postal rates, product offerings and service standards. We sometimes participate in the proceedings before the Postal Regulatory Commission in an attempt to secure fair postal rates for competitive services.

Customs

We are subject to the customs laws in the countries in which we operate, regarding the import and export of shipments, including those related to the filing of documents on behalf of client importers and exporters.

Environmental

We are subject to federal, state and local environmental laws and regulations across all of our business units. These laws and regulations cover a variety of processes, including, but not limited to: proper storage, handling, and disposal of hazardous and other waste; managing wastewater and stormwater; monitoring and maintaining the integrity of underground storage tanks; complying with laws regarding clean air, including those governing emissions; protecting against and appropriately responding to spills and releases; and communicating the presence of reportable quantities of hazardous materials to local responders. UPS has established site- and activity-specific environmental compliance and pollution prevention programs to address our environmental responsibilities and remain compliant. In addition, UPS has created numerous programs which seek to minimize waste and prevent pollution within our operations.

You should carefully consider the following factors, which could materially affect our business, financial condition or results of operations. You should read these Risk Factors in conjunction with “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in Item 7 and our Consolidated Financial Statements and related notes in Item 8.

General economic conditions, both in the U.S. and internationally, may adversely affect our results of operations.

We conduct operations in over 220 countries and territories. Our U.S. and international operations are subject to normal cycles affecting the economy in general, as well as the local economic environments in which we operate. The factors that create cyclical changes to the economy and to our business are beyond our control, and it may be difficult for us to adjust our business model to mitigate the impact of these factors. In particular, our business is affected by levels of industrial production, consumer spending and retail activity, and our business, financial position and results of operations could be materially affected by adverse developments in these aspects of the economy.

We face significant competition which could adversely affect our business, financial position and results of operations.

We face significant competition on a local, regional, national and international basis. Our competitors include the postal services of the U.S. and other nations, various motor carriers, express companies, freight forwarders, air couriers and others. Competition may also come from other sources in the future. Some of our competitors have cost and organizational structures that differ from ours and may offer services and pricing terms that we may not be willing or able to offer. If we are unable to timely and appropriately respond to competitive pressures, our business, financial position and results of operations could be adversely affected.

The transportation industry continues to consolidate and competition remains strong. As a result of consolidation, our competitors may increase their market share and improve their financial capacity, and may strengthen their competitive positions. Business combinations could also result in competitors providing a wider variety of services and products at competitive prices, which could adversely affect our financial performance.

Our business is subject to complex and stringent regulation in the U.S. and internationally.

We are subject to complex and stringent aviation, transportation, environmental, security, labor, employment and other governmental laws and regulations, both in the U.S. and in the other countries in which we operate. In addition, our business is impacted by laws and regulations that affect global trade, including tariff and trade policies, export requirements, taxes and other restrictions and charges. Changes in laws, regulations and the related interpretations may alter the landscape in which we do business and may affect our costs of doing business. The impact of new laws and regulations cannot be predicted. Compliance with new laws and regulations may increase our operating costs or require significant capital expenditures. Any failure to comply with applicable laws or regulations in the U.S. or in any of the countries in which we operate could result in substantial fines or possible revocation of our authority to conduct our operations, which could adversely affect our financial performance.

Increased security requirements could impose substantial costs on us and we could be the target of an attack or have a security breach.

As a result of concerns about global terrorism and homeland security, governments around the world have adopted or may adopt stricter security requirements that will result in increased operating costs for businesses in

14

Table of Contents

the transportation industry. These requirements may change periodically as a result of regulatory and legislative requirements and in response to evolving threats. We cannot determine the effect that these new requirements will have on our cost structure or our operating results, and these rules or other future security requirements may increase our costs of operations and reduce operating efficiencies. Regardless of our compliance with security requirements or the steps we take to secure our facilities or fleet, we could be the target of an attack or security breaches could occur, which could adversely affect our operations or our reputation.

We may be affected by global climate change or by legal, regulatory or market responses to such potential change.

Concern over climate change, including the impact of global warming, has led to significant federal, state and international legislative and regulatory efforts to limit greenhouse gas (“GHG”) emissions. For example, in the past several years, the U.S. Congress has considered various bills that would regulate GHG emissions. While these bills have not yet received sufficient Congressional support for enactment, some form of federal climate change legislation is possible in the future. Even in the absence of such legislation, the Environmental Protection Agency, spurred by judicial interpretation of the Clean Air Act, may regulate GHG emissions, especially aircraft or diesel engine emissions, and this could impose substantial costs on us. These costs include an increase in the cost of the fuel and other energy we purchase and capital costs associated with updating or replacing our aircraft or vehicles prematurely. Until the timing, scope and extent of any future regulation becomes known, we cannot predict its effect on our cost structure or our operating results. It is reasonably possible that such legislation or regulation could impose material costs on us. Moreover, even without such legislation or regulation, increased awareness and any adverse publicity in the global marketplace about the GHGs emitted by companies in the airline and transportation industries could harm our reputation and reduce customer demand for our services, especially our air services.

Strikes, work stoppages and slowdowns by our employees could adversely affect our business, financial position and results of operations.

A significant number of our employees are employed under a national master agreement and various supplemental agreements with local unions affiliated with the Teamsters and our airline pilots, airline mechanics, ground mechanics and certain other employees are employed under other collective bargaining agreements. Strikes, work stoppages and slowdowns by our employees could adversely affect our ability to meet our customers’ needs, and customers may do more business with competitors if they believe that such actions or threatened actions may adversely affect our ability to provide services. We may face permanent loss of customers if we are unable to provide uninterrupted service, and this could adversely affect our business, financial position and results of operations. The terms of future collective bargaining agreements also may affect our competitive position and results of operations.

We are exposed to the effects of changing prices of energy, including gasoline, diesel and jet fuel, and interruptions in supplies of these commodities.

Changing fuel and energy costs may have a significant impact on our operations. We require significant quantities of fuel for our aircraft and delivery vehicles and are exposed to the risk associated with variations in the market price for petroleum products, including gasoline, diesel and jet fuel. We mitigate our exposure to changing fuel prices through our indexed fuel surcharges and we may also enter into hedging transactions from time to time. If we are unable to maintain or increase our fuel surcharges, higher fuel costs could adversely impact our operating results. Even if we are able to offset the cost of fuel with our surcharges, high fuel surcharges may result in a mix shift from our higher yielding air products to lower yielding ground products or an overall reduction in volume. If fuel prices rise sharply, even if we are successful in increasing our fuel surcharge, we could experience a lag time in implementing the surcharge, which could adversely affect our short-term operating results. There can be no assurance that our hedging transactions will be effective to protect us

15

Table of Contents

from changes in fuel prices. Moreover, we could experience a disruption in energy supplies, including our supply of gasoline, diesel and jet fuel, as a result of war, actions by producers, or other factors which are beyond our control, which could have an adverse effect on our business.

Changes in exchange rates or interest rates may have an adverse effect on our results.

We conduct business across the globe with a significant portion of our revenue derived from operations outside the United States. Our operations in international markets are affected by changes in the exchange rates for local currencies, and in particular the Euro, British Pound Sterling and Canadian Dollar.

We are exposed to changes in interest rates, primarily on our short-term debt and that portion of our long-term debt that carries floating interest rates. The impact of a 100-basis-point change in interest rates affecting our debt is discussed in the “Quantitative and Qualitative Disclosures about Market Risk” section of this report.

We monitor and manage our exposures to changes in currency exchange rates and interest rates, and make limited use of currency exchange contracts, over the counter option contracts, commodity forwards, swaps and futures contracts to mitigate the impact of changes in currency values, but changes in exchange rates and interest rates cannot always be predicted or hedged.

If we are unable to maintain our brand image and corporate reputation, our business may suffer.

Our success depends in part on our ability to maintain the image of the UPS brand and our reputation for providing excellent service to our customers. Service quality issues, actual or perceived, even when false or unfounded, could tarnish the image of our brand and may cause customers to use other companies. Also, adverse publicity surrounding labor relations, environmental concerns, security matters, political activities and the like, or attempts to connect our company to these sorts of issues, either in the United States or other countries in which we operate, could negatively affect our overall reputation and acceptance of our services by customers. Damage to our reputation and loss of brand equity could reduce demand for our services and thus have an adverse effect on our business, financial position and results of operations, and could require additional resources to rebuild our reputation and restore the value of our brand.

A significant privacy breach or IT system disruption could adversely affect our business and we may be required to increase our spending on data and system security.

We rely on information technology networks and systems, including the Internet, to process, transmit and store electronic information, and to manage or support a variety of business processes and activities. In addition, the provision of service to our customers and the operation of our network involve the storage and transmission of proprietary information and sensitive or confidential data, including personal information of customers, employees and others. Our information technology systems, some of which are managed by third-parties, may be susceptible to damage, disruptions or shutdowns due to failures during the process of upgrading or replacing software, databases or components thereof, power outages, hardware failures, computer viruses, attacks by computer hackers, telecommunication failures, user errors or catastrophic events. Groups of hackers may also act in a coordinated manner to launch distributed denial of service attacks or other coordinated attacks that may cause service outages or other interruptions. In addition, breaches in security could expose us, our customers or the individuals affected to a risk of loss or misuse of proprietary information and sensitive or confidential data. Any of these occurrences could result in disruptions in our operations, the loss of existing or potential customers, damage to our brand and reputation, and litigation and potential liability for the company. In addition, the cost and operational consequences of implementing further data or system protection measures could be significant.

Severe weather or other natural or manmade disasters could adversely affect our business.

Severe weather conditions and other natural or manmade disasters, including storms, floods, fires and earthquakes, may result in decreased revenues, as our customers reduce their shipments, or increased costs to

16

Table of Contents

operate our business, which could have an adverse effect on our results of operations for a quarter or year. Any such event affecting one of our major facilities could result in a significant interruption in or disruption of our business.

We make significant capital investments in our business of which a significant portion is tied to projected volume levels.

We require significant capital investments in our business consisting of aircraft, vehicles, technology, facilities and sorting and other types of equipment to support both our existing business and anticipated growth. Forecasting projected volume involves many factors which are subject to uncertainty, such as general economic trends, changes in governmental regulation and competition. If we do not accurately forecast our future capital investment needs, we could have excess capacity or insufficient capacity, either of which would negatively affect our revenues and profitability. In addition to forecasting our capital investment requirements, we adjust other elements of our operations and cost structure in response to adverse economic conditions; however, these adjustments may not be sufficient to allow us to maintain our operating margins in an adverse economy.

We derive a significant portion of our revenues from our international operations and are subject to the risks of doing business in emerging markets.

We have significant international operations and while the geographical diversity of our international operations helps ensure that we are not overly reliant on a single region or country, we are continually exposed to changing economic, political and social developments beyond our control. Emerging markets are typically more volatile than those in the developed world, and any broad-based downturn in these markets could reduce our revenues and adversely affect our business, financial position and results of operations.

We are subject to changes in markets and our business plans that have resulted, and may in the future result, in substantial write-downs of the carrying value of our assets, thereby reducing our net income.

Our regular review of the carrying value of our assets has resulted, from time to time, in significant impairments, and we may in the future be required to recognize additional impairment charges. Changes in business strategy, government regulations, or economic or market conditions have resulted and may result in further substantial impairments of our intangible or other assets at any time in the future. In addition, we have been and may be required in the future to recognize increased depreciation and amortization charges if we determine that the useful lives of our fixed assets are shorter than we originally estimated. Such changes could reduce our net income.

Employee health and retiree health and pension benefit costs represent a significant expense to us.

With approximately 398,000 employees, including approximately 323,000 in the U.S., our expenses relating to employee health and retiree health and pension benefits are significant. In recent years, we have experienced significant increases in certain of these costs, largely as a result of economic factors beyond our control, including, in particular, ongoing increases in health care costs well in excess of the rate of inflation. Continued increasing health care costs, volatility in investment returns and discount rates, as well as changes in laws, regulations and assumptions used to calculate retiree health and pension benefit expenses, may adversely affect our business, financial position, results of operations or require significant contributions to our pension plans.

We participate in a number of trustee-managed multiemployer pension and health and welfare plans for employees covered under collective bargaining agreements. Several factors could cause us to make significantly higher future contributions to these plans, including unfavorable investment performance, increases in health care costs, changes in demographics and increased benefits to participants. At this time, we are unable to determine the amount of additional future contributions, if any, or whether any material adverse effect on our financial condition, results of operations or liquidity could result from our participation in these plans.

17

Table of Contents

We may be subject to various claims and lawsuits that could result in significant expenditures.

The nature of our business exposes us to the potential for various claims and litigation related to labor and employment, personal injury, property damage, business practices, environmental liability and other matters. Any material litigation or a catastrophic accident or series of accidents could have a material adverse effect on our business, financial position and results of operations.

We may not realize the anticipated benefits of acquisitions, joint ventures or strategic alliances.

As part of our business strategy, we may acquire businesses and form joint ventures or strategic alliances. Whether we realize the anticipated benefits from these transactions depends, in part, upon the successful integration between the businesses involved, the performance of the underlying operation, capabilities or technologies and the management of the transacted operations. Accordingly, our financial results could be adversely affected by our failure to effectively integrate the acquired operations, unanticipated performance issues, transaction-related charges or charges for impairment of long-term assets that we acquire.

Insurance and claims expenses could have a material adverse effect on our business, financial condition and results of operations.

We have a combination of both self-insurance and high-deductible insurance programs for the risks arising out of the services we provide and the nature of our global operations, including claims exposure resulting from cargo loss, personal injury, property damage, aircraft and related liabilities, business interruption and workers’ compensation. Workers’ compensation, automobile and general liabilities are determined using actuarial estimates of the aggregate liability for claims incurred and an estimate of incurred but not reported claims, on an undiscounted basis. Our accruals for insurance reserves reflect certain actuarial assumptions and management judgments, which are subject to a high degree of variability. If the number or severity of claims for which we are retaining risk increases, our financial condition and results of operations could be adversely affected. If we lose our ability to self-insure these risks, our insurance costs could materially increase and we may find it difficult to obtain adequate levels of insurance coverage.

Not applicable.

Operating Facilities

We own our headquarters, which are located in Atlanta, Georgia and consist of about 735,000 square feet of office space on an office campus, and our UPS Supply Chain Solutions group’s headquarters, which are located in Alpharetta, Georgia, and consist of about 310,000 square feet of office space.

We also own our 27 principal U.S. package operating facilities, which have floor spaces that range from approximately 310,000 to 693,000 square feet. In addition, we have a 1.9 million square foot operating facility near Chicago, Illinois, which is designed to streamline shipments between East Coast and West Coast destinations, and we own or lease over 1,000 additional smaller package operating facilities in the U.S. The smaller of these facilities have vehicles and drivers stationed for the pickup of packages and facilities for the sorting, transfer and delivery of packages. The larger of these facilities also service our vehicles and equipment and employ specialized mechanical installations for the sorting and handling of packages.

We own or lease almost 800 facilities that support our international package operations and an additional 800 facilities that support our freight forwarding and logistics operations. Our freight forwarding and logistics operations maintain facilities with approximately 35 million square feet of floor space. We own and operate a logistics campus consisting of approximately 3.1 million square feet in Louisville, Kentucky.

Table of Contents

UPS Freight operates 196 service centers with a total of 5.9 million square feet of floor space. UPS Freight owns 148 of these service centers, while the remainder are occupied under operating lease agreements. The main offices of UPS Freight are located in Richmond, Virginia and consist of about 240,000 square feet of office space.

Our aircraft are operated in a hub and spokes pattern in the U.S. Our principal air hub in the U.S., known as Worldport, is located in Louisville, Kentucky. The Worldport facility consists of over 5.2 million square feet and the site includes approximately 596 acres. Between 2009 and 2010, we completed an expansion of our Worldport facility, which increased the sorting capacity to approximately 416,000 packages per hour. The expansion, which cost over $1 billion, involved the addition of two aircraft load / unload wings to the hub building, followed by the installation of high-speed conveyor and computer control systems.

We also have regional air hubs in Hartford, Connecticut; Ontario, California; Philadelphia, Pennsylvania; and Rockford, Illinois. These hubs house facilities for the sorting, transfer and delivery of packages. Our European air hub is located in Cologne, Germany, and we maintain Asia-Pacific air hubs in Shanghai, China; Shenzhen, China; Taipei, Taiwan; Hong Kong; and Singapore. Our regional air hub in Canada is located in Hamilton, Ontario, and our regional air hub for Latin America and the Caribbean is in Miami, Florida.

In 2011, we announced plans to significantly expand our European air hub in Cologne, Germany. The expansion project, due to be completed by the end of 2013, will equip the existing facility with additional state-of-art technology and will include a major extension to the existing building. This extension would be partially dedicated to processing larger freight shipments. Together these initiatives will significantly increase the hub’s package sorting capacity from today’s 110,000 to 190,000 packages per hour. The total cost of the expansion is estimated to be approximately $200 million.

Over the past several years, UPS has made a successful transition to become the first wholly-owned foreign express carrier in China. In 2008, we opened the UPS International Air Hub at Pudong International Airport, which was built on a parcel totaling 2.4 million square feet with a planned sorting capacity of 17,000 packages per hour. The hub links all of China via Shanghai to UPS’s international network with direct service to the Americas, Europe and Asia. It also connects points served in China by UPS through a dedicated service provided by Yangtze River Express, a Chinese all-cargo airline.

In February 2010, we opened a new intra-Asia air hub at Shenzhen Baoan International Airport in China. The Shenzhen facility replaced our intra-Asia air hub at Clark Air Force Base in the Philippines, and serves as our primary transit hub in Asia. The facility was built on a parcel of almost 1 million square feet, and has a sorting capacity of 18,000 packages per hour.

Our primary information technology operations are consolidated in a 435,000 square foot owned facility, the Ramapo Ridge facility, which is located on a 39-acre site in Mahwah, New Jersey. We also own a 175,000 square foot facility located on a 25-acre site in Alpharetta, Georgia, which serves as a backup to the main information technology operations facility in New Jersey. This facility provides production functions and backup capacity in the event that a power outage or other disaster incapacitates the main data center. It also helps to meet our internal communication needs.

We believe that our facilities are adequate to support our current operations.

PART II

Our class A common stock is not listed on a national securities exchange or traded in an organized over-the-counter market, but each share of our class A common stock is convertible into one share of our class B common stock.

The following is a summary of our class B common stock price activity and dividend information for 2011 and 2010. Our class B common stock is listed on the New York Stock Exchange under the symbol “UPS.”

As of January 31, 2012, there were 157,455 and 18,024 record holders of class A and class B common stock, respectively.

The policy of our Board of Directors is to declare dividends out of current earnings. The declaration of dividends is subject to the discretion of the Board of Directors and will depend on various factors, including our net income, financial condition, cash requirements, future prospects, and other relevant factors.

On February 9, 2012, our Board declared a dividend of $0.57 per share, which is payable on March 7, 2012 to shareowners of record on February 21, 2012. This represents a 10% increase from the previous $0.52 quarterly dividend in 2011.

In January 2008, the Board of Directors approved an increase in our share repurchase authorization to $10.0 billion. Share repurchases may take the form of accelerated share repurchases, open market purchases, or other such methods as we deem appropriate. The timing of our share repurchases will depend upon market conditions. Unless terminated earlier by the resolution of our Board, the program will expire when we have purchased all shares authorized for repurchase under the program.

A summary of repurchases of our class A and class B common stock during the fourth quarter of 2011 is as follows (in millions, except per share amounts):

Overview

The slow pace of the U.S. economic recovery in 2011 put pressure during the first three quarters of the year on volume and revenue growth in our U.S. Domestic Package segment, as well as U.S. import volume in our International Package and Supply Chain & Freight segments. Slower growth in industrial production and the lack of significant inventory rebuilding also pressured our volume in certain industrial sectors; however, overall growth in retail sales, particularly in e-commerce, resulted in solid business-to-consumer shipment activity during the year. Growth accelerated in the fourth quarter of 2011 due in large part to a strong holiday season for e-commerce sales, which resulted in higher volume and revenue for our deferred and ground residential products.

Outside of the U.S., economic growth slowed throughout 2011 due to volatility in world markets. Despite this sluggish economic environment, we experienced favorable volume and revenue growth for most of the year, although the growth trend slowed during the latter half of 2011.

In 2011, we continued to undertake initiatives to improve yield management, increase operational efficiency and contain costs, which led to solid improvements in operating margin and profit in our U.S. Domestic Package and Supply Chain & Freight segments. During 2010, we completed the second phase of our Worldport expansion which has allowed the use of larger and more fuel-efficient aircraft, and further improved network efficiencies. We also streamlined our U.S. domestic management structure and continued to better align our cost structure with prevailing volume levels.

In our International Package segment, we have continued to invest to support our growth initiatives. In 2010, we opened our new intra-Asia air hub in Shenzhen, China, which has allowed us to better serve our customers by reducing time in transit for shipments in the region. We have also continued to optimize our aircraft network, to leverage the new route authority we have gained over the last several years and to take full advantage of faster growing trade lanes. In Asia, we expanded our air network during 2011 by adding flights from Hong Kong to Cologne, Germany, adding a daily flight from Chengdu, China to Cologne, and adding new routes from Japan, as well as increasing our capacity to serve the South Korea to U.S. trade lane by adding a flight to and from Incheon. In Europe, we announced a $200 million expansion of our Cologne hub in Germany in 2011, which will increase the hub’s sorting capacity from 110,000 to 190,000 packages per hour when completed in 2013. In the Americas, we have expanded our air capacity more than 50% on 19 weekly flights into key markets in Central and South America during 2011.

Even though we continue to experience solid overall growth in our International Package business, in the latter half of 2011, we experienced weakness in the important Asia-to-U.S. trade lane. To align our capacity and cost structure with prevailing volume levels, we reduced our tonnage capacity in this lane, while retaining the network enhancements and service upgrades previously implemented.

Volatile fuel prices have continued to impact both revenue and expense in all three of our segments. Rising fuel prices have led to higher fuel surcharge rates and increased fuel and purchased transportation costs.

Our consolidated results are presented in the table below:

Items Affecting Comparability

The year-over-year comparisons of our financial results are affected by the following items (in millions):

Pension and Postretirement Benefit Plans Mark-to-Market Charge

In 2011, 2010 and 2009, we incurred pre-tax mark-to-market losses on our pension and postretirement benefit plans related to the remeasurement of plan assets and liabilities recognized outside of a 10% corridor of $827, $112 and $16 million, respectively, on a consolidated basis ($527, $75 and $11 million after-tax, respectively). These mark-to-market losses for 2011, 2010 and 2009 primarily resulted from decreases in the discount rates used to value our projected benefit obligations in each year. These charges impacted each of our three reporting segments in 2011 and 2010, and our International Package segment in 2009.

Restructuring Charge

In 2010, we streamlined the management structure in our U.S. Domestic Package segment, and incurred a restructuring charge associated with this reorganization. This pre-tax charge totaled $98 million ($64 million after-tax), and reflects the value of voluntary retirement benefits, severance benefits and unvested stock compensation.

Gain on Sales of Businesses

In 2010, we sold our UPS Logistics Technologies business unit within our Supply Chain & Freight segment, and recognized a pre-tax gain of $71 million ($44 million after-tax). Also in 2010, we sold a specialized

25

Table of Contents

transportation business in Germany within our Supply Chain & Freight segment, and incurred a pre-tax loss on the sale of $51 million ($47 million after-tax), which includes a fair value adjustment loss due to a financial guarantee associated with this business sale.

Gains on Real Estate Transactions

In 2011, we recognized a net $33 million pre-tax gain ($20 million after-tax) on a consolidated basis on certain real estate transactions (consisting of a $48 million pre-tax gain in our Supply Chain & Freight segment, and a $15 million pre-tax loss in our U.S. Domestic Package segment). In 2010, we recognized a pre-tax gain of $109 million ($61 million after-tax) on the sale of real estate within our U.S. Domestic Package segment.

Aircraft Impairment Charges

In 2009, we completed an impairment assessment of our McDonnell-Douglas DC-8 aircraft fleet, and recorded an impairment charge of $181 million ($116 million after-tax), which affected our U.S. Domestic Package segment. This charge, as well as our accounting policies pertaining to long-lived assets, is discussed further in “Critical Accounting Policies and Estimates”.

Currency Remeasurement Charge

During 2009, we incurred a $77 million non-cash, pre-tax currency remeasurement charge ($48 million after-tax) on certain foreign currency denominated obligations.

Charge for Change in Tax Filing Status for German Subsidiary

In 2010, we changed the tax status of a German subsidiary that was taxable in the U.S. and its local jurisdiction to one that is solely taxed in its local jurisdiction. As a result of this change in tax status, we recorded a non-cash charge of $76 million to income tax expense, which resulted primarily from the write-off of related deferred tax assets which will not be realizable following the change in tax status.

Results of Operations—Segment Review

The results and discussions that follow are reflective of how our executive management monitors the performance of our reporting segments. We supplement the reporting of our financial information determined under generally accepted accounting principles (“GAAP”) with certain non-GAAP financial measures, including operating profit, operating margin, pre-tax income, net income and earnings per share adjusted for the non-comparable items discussed previously. We believe that these adjusted measures provide meaningful information to assist investors and analysts in understanding our financial results and assessing our prospects for future performance. We believe these adjusted financial measures are important indicators of our recurring results of operations because they exclude items that may not be indicative of, or are unrelated to, our core operating results, and provide a better baseline for analyzing trends in our underlying businesses.

U.S. Domestic Package Operations

Revenue

The change in overall revenue was impacted by the following factors for the years ended December 31, 2011 and 2010, compared with the prior years:

Volume

2011 compared to 2010

Our overall volume increased slightly in 2011 compared with 2010, and was largely impacted by the slowing U.S. economy during the first three quarters of the year. Business-to-consumer shipments, which

represent approximately 40% of total U.S. Domestic Package volume, experienced stronger growth than commercial volume. Volume growth accelerated in the fourth quarter, with average daily volume increasing 3.8% over the fourth quarter of 2010.

Among our air products, we experienced a 4.8% increase in Next Day and Second Day air package volume, as a result of retail sales growth, with particular growth in our Next Day Air Saver product. Air letter volume declined, largely due to weakness in the financial and other service industries. Within ground, our light weight products, which target low-cost, non-urgent ground residential deliveries, experienced solid growth during 2011. During the fourth quarter of 2011, volume growth accelerated to 12.3% and 3.5% in our deferred and ground products, respectively, compared with the fourth quarter of 2010. These increases were primarily driven by higher business-to-consumer shipment growth during the holiday season.

2010 compared to 2009

In 2010, our overall volume increased as improvements in industrial production and retail sales increased overall demand in the U.S. small package market. Among our air products, Next Day and Second Day air package volume increased 2.1% as inventory rebuilding in the manufacturing and retailing sectors contributed to growth. However, our letter volume declined largely due to weakness in the financial and other service industries. The growth in ground volume was driven by increased volume from the manufacturing and retailing sectors.

Rates and Product Mix

2011 compared to 2010

Overall revenue per piece increased for our ground and air products during 2011 due to a combination of base price increases and fuel surcharge rate changes, which are discussed further below. The overall revenue per piece increase was also positively affected by our focus on revenue management initiatives. In addition, the revenue per piece increase for our air products was positively impacted by the overall mix shift from letters to packages. Comparing the fourth quarter of 2011 with 2010, the average revenue per piece increase slowed to 3.4% due to the higher volume of lighter-weight business-to-consumer packages.

Revenue per piece for our ground and air products was also impacted by an increase in base rates that took effect on January 3, 2011. We increased the base rates 6.9% on UPS Next Day Air, UPS 2nd Day Air, and UPS 3 Day Select, and 5.9% on UPS Ground, while reducing our fuel surcharge indexes (discussed further below). Other pricing changes included an increase in the residential surcharge, and an increase in the delivery area surcharge on both residential and commercial services to certain ZIP codes.

2010 compared to 2009

Overall revenue per piece increased for our ground and air products in 2010, largely due to a combination of base price increases and fuel surcharge rate changes, which are discussed further below. The revenue per piece for our air products also improved as a result of higher average package weights and the overall mix shift from letters to packages. For both our air and ground products, revenue per piece was negatively affected by a shift in product mix to our less premium services, such as Next Day Air Saver and Ground Basic.

Revenue per piece for our ground and air products was impacted by an increase in base rates that took effect on January 4, 2010. We increased the base rates 6.9% on UPS Next Day Air, UPS 2nd Day Air, and UPS 3 Day Select, and 4.9% on UPS Ground. Other pricing changes included an increase in the residential surcharge, and an increase in the delivery area surcharge on both residential and commercial services to certain ZIP codes.

Fuel Surcharges

UPS applies a fuel surcharge on our domestic air and ground services. The air fuel surcharge is based on the U.S. Department of Energy’s (“DOE”) Gulf Coast spot price for a gallon of kerosene-type jet fuel, while the ground fuel surcharge is based on the DOE’s On-Highway Diesel Fuel Price. Based on published rates, the average fuel surcharge for domestic air and ground products was as follows:
