This report and our other filings with the Securities and Exchange Commission ("SEC") contain and in the future may contain "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995. Statements other than those of current or historical fact, and all statements accompanied by terms such as "will," "believe," "project," "expect," "estimate," "assume," "intend," "anticipate," "target," "plan" and similar terms, are intended to be forward-looking statements. Forward-looking statements are made subject to the safe harbor provisions 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.

From time to time, we also include written or oral forward-looking statements in other publicly disclosed materials. Such statements may relate to our intent, belief, forecasts of, or current expectations about our strategic direction, prospects, future results or 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 and the future, by its very nature, cannot be predicted with certainty.

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 include, but are not limited to, those described in Part I, "Item 1A. Risk Factors" and elsewhere in this report 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, except as required by law.

From time to time, we expect to participate in analyst and investor conferences. Materials provided or displayed at those conferences, such as slides and presentations, may be posted on our investor relations website at www.investors.ups.com under the heading "Presentations" when made available. These presentations may contain new material nonpublic information about our company and you are encouraged to monitor this site for any new posts, as we may use this mechanism as a public announcement.

United Parcel Service, Inc. ("UPS"), founded in 1907, is the world’s premier package delivery company and a leading provider of global supply chain management solutions. We offer a broad range of industry-leading products and services through our extensive global presence. Our services include transportation and delivery, distribution, contract logistics, ocean freight, airfreight, customs brokerage and insurance.

We operate one of the largest airlines and one of the largest fleets of alternative fuel vehicles under a global UPS brand. We deliver packages each business day for approximately 1.6 million shipping customers to 10.2 million delivery recipients in over 200 countries and territories. In 2023, we delivered an average of 22.3 million packages per day, totaling 5.7 billion packages during the year. Total revenue in 2023 was $91.0 billion.

Innovation Driven is designed to optimize the volume that flows through our network to focus on increasing value share and to drive business growth from higher-yielding opportunities in our target markets. We continue to leverage data and automation to deliver improvements to our network and unlock additional value for our customers through innovation.

Global Smart Logistics Network. We believe that our integrated global air and ground network is the most extensive in the industry. We provide all types of package services (air, ground, domestic, international, commercial and residential) through a single pickup and delivery network. Our sophisticated systems, including our RFID-enabled Smart Package, Smart Facility technology, allow us to optimize network efficiency and asset utilization, and enhance end-to-end shipment visibility.

Cutting-Edge Technologies. We are a global leader in developing technologies that help customers enhance their shipping and logistics business processes to lower costs, improve service and increase efficiency. We offer a variety of digital tools and capabilities that enable customers to integrate UPS functionality into their distribution channels, deepening customer relationships. These tools allow customers to send, manage and track their shipments, and also provide their customers with value-added data.

Broad Portfolio of Services. Our service portfolio allows customers to choose their most appropriate delivery option. Increasingly, our customers benefit from UPS business solutions that integrate our services beyond package delivery. For example, our supply chain services are designed to improve the efficiency and resilience of customers’ entire supply chain management process.

Distinctive Culture. We believe that the dedication of our employees comes in large part from our purpose-driven culture that fosters trust, partnership and empowerment. We encourage our people to bring their unique perspectives, background, talents and skills to work every day. Our legacy of fairness and equity is the bedrock of our culture and of our relationships with those we serve.

Financial Strength. Our financial strength allows us to continue to pursue strategic opportunities that facilitate our growth. This includes investing in digital technology, acquisitions, transportation equipment, facilities and employee development to generate value for shareholders. We seek to maintain a strong credit rating to give us additional flexibility in running the business.

Our global small package operations provide time-definite delivery services for express letters, documents, packages and palletized freight via air and ground services. These services are supported by numerous shipping, visibility and billing technologies including our Digital Access Program, which embeds our shipping solutions directly into leading e-commerce platforms, enabling us to more broadly reach small- and medium-sized businesses and e-commerce markets.

All of our services are managed through a single, global smart logistics network. We combine all packages within this single network, unless dictated by specific service commitments. This enables us to efficiently pick up customers’ shipments for any services at a scheduled time each day. Our global smart logistics network provides unique operational and capital efficiencies that also have a lesser environmental impact than single service network designs.

We offer same-day pickup of air and ground packages seven days a week. Our global smart logistics network offers approximately 180,000 entry points where customers can tender packages to us at locations and times convenient to them. This includes UPS drivers who can accept packages, UPS drop boxes, UPS Access Point locations, The UPS Store locations, authorized shipping outlets and commercial counters, alliance locations and customer centers attached to UPS facilities.

We offer a portfolio of returns services in more than 140 countries. These services are driven by the continued growth of e-commerce that has increased our customers' need for efficient and reliable returns, and are designed to promote efficiency and a friction-free consumer experience. This portfolio provides a range of cost-effective label and digital returns options and a broad network of consumer drop points. To accelerate growth of this portfolio, in the fourth quarter of 2023 we acquired Happy Returns, a technology-focused company that is managed and reported within Supply Chain Solutions, to provide innovative end-to-end return services and a consolidated returns solution for our enterprise retail customers.

Our global air operations hub is located in Louisville, Kentucky, and is supported by air hubs across the United States ("U.S.") and internationally. We operate international air hubs in Germany, China, Hong Kong, Canada and Florida (for Latin America and the Caribbean). This design enables cost-effective package processing using fewer, larger and more fuel-efficient aircraft.

International Package consists of our small package operations in Europe, the Indian sub-continent, Middle East and Africa (together "EMEA"), Canada and Latin America (together "Americas") and Asia. We offer a wide selection of guaranteed day- and time-definite international shipping services, including more guaranteed time-definite express options than any other carrier.

For international package shipments that do not require express services, UPS Worldwide Expedited offers a reliable, deferred, guaranteed day-definite service option. For cross-border ground package delivery, we offer UPS Standard delivery services within Europe, between the U.S. and Canada, and between the U.S. and Mexico. UPS Worldwide Express Freight is a premium international service for urgent, palletized shipments over 150 pounds.

We are one of the largest U.S. domestic airfreight carriers and airfreight forwarders globally. We offer a portfolio of guaranteed and non-guaranteed global airfreight services. Additionally, as one of the world’s leading non-vessel operating common carriers, we provide ocean freight full container load, less-than-container load and multimodal transportation services between most major ports around the world.

We are among the world’s largest customs brokers, measured by both the number of shipments processed annually and by the number of dedicated brokerage employees worldwide. In addition to customs clearance services, we provide product classification, trade management, duty drawback and consulting services.

We provide brokerage services that coordinate a fleet of less-than-truckload and truckload vehicles for shipments requiring ground freight transportation in North America and Europe. Access to the UPS fleet, combined with a broad third-party carrier network, enables us to create capacity solutions for customers of all sizes across industries, delivered through a combination of people and technology. Customers can also access UPS services such as airfreight, customs brokerage and global freight forwarding.

Our global logistics and distribution business provides value-added fulfillment and transportation management services. We leverage a network of facilities in over 120 countries to seek to ensure products and parts are in the right place at the right time. We operate both multi-client and dedicated facilities across our network, many of which are strategically located near UPS air and ground transportation hubs to support rapid delivery to business and consumer markets. We continue to invest in the automation of our facilities to meet customer demand.

We offer world-class technology, deep expertise and a highly sophisticated suite of healthcare logistics services. With a strategic focus on serving the unique, priority-handling needs of healthcare and life sciences customers, we continue to increase our complex cold-chain logistics capabilities both in the U.S. and internationally. In furtherance of this strategy and to broaden our reach and services, we recently acquired Bomi Group and MNX Global Logistics.

Our digital businesses leverage technology to enable a range of on-demand services. Roadie offers customers the convenience of same-day delivery, while Happy Returns offers innovative end-to-end return services that leverage The UPS Store network. We also offer integrated supply chain and high-value shipment insurance solutions to both small and large businesses through UPS Capital, as well as a range of services through our other Supply Chain Solutions businesses. We believe these services are important to meeting customers' needs and deepening customer relationships.

Our success is dependent upon our people, working together with a common purpose. As we seek to capture new opportunities and pursue growth, we believe that transforming the UPS employee experience is foundational to our success. This requires a thoughtful balance between the culture we have cultivated over the years and the new perspectives we need to take the business into the future.

We believe that UPS employees are among the most motivated and highest performing in the industry and provide us a competitive advantage. To assist with employee recruitment and retention, we continue to review the competitiveness of our employee value proposition, including benefits and pay, training, talent development and promotion opportunities. For additional information on the importance of our human capital efforts, see "Risk Factors - Business and Operating Risks - Failure to attract or retain qualified employees could materially adversely affect us" and "- Strikes, work stoppages or slowdowns by our employees could materially adversely affect us".

We have approximately 500,000 employees (excluding temporary seasonal employees), of which 414,000 are in the U.S. and 86,000 are located internationally. Our global workforce includes approximately 85,000 management employees (42% of whom are part-time) and 415,000 hourly employees (48% of whom are part-time). More than 70% of our U.S. employees are represented by unions, primarily those employees handling or transporting packages. Many of these employees are employed under a national master agreement and various supplemental agreements with local unions affiliated with the International Brotherhood of Teamsters ("Teamsters"). In the third quarter of 2023, the Teamsters fully ratified a new national master agreement that expires July 31, 2028. In addition, approximately 3,300 of our pilots are represented by the Independent Pilots Association ("IPA"). Our agreement with the IPA becomes amendable September 1, 2025.

Our board, directly and through the Compensation and Human Capital Committee, is responsible for oversight of human capital matters. Effective oversight is accomplished through a variety of methods and processes including regular updates and discussions around human capital transformation efforts, technology initiatives impacting the workforce, health and safety matters, employee survey results related to culture and other matters, hiring and retention, employee demographics, labor relations and contract negotiations, compensation and benefits, succession planning and employee training initiatives.

In addition, the Compensation and Human Capital Committee charter has been expanded to include oversight responsibility for performance and talent management, diversity, equity and inclusion, work culture and employee development and retention. We believe the board’s oversight of these matters helps identify and mitigate exposure to labor and human capital management risks and is part of the broader framework that guides how we attract, retain and develop a workforce that aligns with our values and strategies.

We bargain in good faith with the unions that represent our employees. We frequently engage union leaders at the national level and at local chapters throughout the United States. We participate in works councils and associations outside the U.S., which allows us to respond to emerging issues abroad. This work helps our operations to build and maintain productive relationships with our employees. For additional information regarding employees employed under collective bargaining agreements, see note 6 to the audited, consolidated financial statements.

Our CHSP covers a wide array of roles, from package handling to administration, and spans geographical boundaries to include sorting facilities, mobile logistics, administrative offices, and other locations worldwide. UPS conducts audits to assess specific risks and hazards, including equipment safety, workplace environment, and emergency response protocols. We monitor our safety performance through various measurable targets, including lost time injury frequency and the number of recorded auto accidents.

Building and maintaining long-term customer relationships through superior service is a competitive strength of UPS. In 2023, we served 1.6 million shipping customers and more than 10.2 million delivery recipients daily. For the year ended December 31, 2023, one customer, Amazon.com, Inc. and its affiliates, represented approximately 11.8% of our consolidated revenues, substantially all of which was within our U.S. Domestic Package segment. For additional information on our customers, see "Risk Factors - Business and Operating Risks - Changes in our relationships with any of our significant customers, including the loss or reduction in business from one or more of them, could have a material adverse effect on us" and note 14 to the audited, consolidated financial statements.

We offer a broad array of transportation and logistics services and compete with many local, regional, national and international logistics providers as well as national postal services. We believe our strategy, network and competitive strengths position us well to compete in the marketplace. For additional information on our competitive environment, see "Risk Factors - Business and Operating Risks - Our industry is rapidly evolving. We expect to continue to face significant competition, which could materially adversely affect us".

We are subject to numerous laws and regulations in the countries in which we operate. Continued compliance with increasingly stringent laws, regulations and policies in the U.S. and in the other countries in which we operate may result in materially increased costs, or we could be subject to substantial fines or possible revocation of our authority to conduct our operations.

The DOT’s authority primarily relates to economic aspects of air transportation, such as operating authority, insurance requirements, pricing, non-competitive practices, interlocking relations and cooperative agreements. The DOT also regulates 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 agreements between the U.S. and foreign governments or, in the absence of such agreements, by principles of reciprocity. We are also subject to current and potential aviation, health, customs and immigration regulations imposed by governments in other countries in which we operate, including registration and license requirements and security regulations. We have 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 subject to DOT and foreign government regulations and operating restrictions.

The FAA’s authority primarily relates to operational, technical and safety aspects of air transportation, including certification, aircraft operating procedures, transportation of hazardous materials, record keeping standards and maintenance activities and personnel. 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.

UPS's aircrew, dispatch and aircraft maintenance certification, training, programs and procedures, including aircraft inspection and repair at periodic intervals, are approved for all aircraft and carrier operations under FAA regulations. The future cost of changes and repairs pursuant to these programs and procedures may fluctuate according to aircraft condition, age and the enactment of additional FAA regulatory requirements.

We participate in the Civil Reserve Air Fleet ("CRAF") program. Our participation in this program allows the U.S. Department of Defense ("DOD") to requisition specified UPS aircraft for military use during a national defense emergency. The DOD is required to compensate us for any use of aircraft under the CRAF program. In addition, participation in the CRAF program entitles us to bid for other U.S. Government opportunities including small package and airfreight.

Our ground transportation of packages in the U.S. is subject to regulation by the DOT and its agency, the Federal Motor Carrier Safety Administration (the "FMCSA"). Ground transportation also falls under state jurisdiction with respect to the regulation of operations, safety and insurance. Our ground transportation of hazardous materials in the U.S. is subject to regulation by the DOT's Pipeline and Hazardous Materials Safety Administration. We also must comply with safety and fitness regulations promulgated by the FMCSA, including those relating to drug and alcohol testing and hours of service for drivers. Ground transportation of packages outside of the U.S. is subject to similar regulatory schemes in the countries in which we transport those packages.

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 U.S. Postal Service, including postal rates, product offerings and service standards. We sometimes participate in proceedings before the Postal Regulatory Commission in an attempt to facilitate compliance with fair competition requirements for competitive services.

We are subject to the customs laws regarding the import and export of shipments in the countries in which we operate, including those related to the filing of documents on behalf of client importers and exporters. Our activities in the U.S., including customs brokerage and freight forwarding, are subject to regulation by the Bureau of Customs and Border Protection, the TSA, the U.S. Federal Maritime Commission and the DOT. Our international operations are subject to similar regulatory structures in their respective jurisdictions.

For additional information, see "Risk Factors – Business and Operating Risks – We maintain significant physical operations. Increases in operational security requirements impose substantial costs on us and we could be the target of an attack or have a security breach, which could materially adversely affect us".

We are subject to U.S. and international federal, state and local environmental laws and regulations across all of our operations. These laws and regulations cover a variety of matters such as disclosures, operations and processes, including, but not limited to: properly storing, handling and disposing of waste materials; appropriately managing waste water and storm water; 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. We maintain site- and activity-specific environmental compliance and pollution prevention programs to address our environmental responsibilities and remain compliant. In addition, we maintain numerous programs which seek to minimize waste and prevent pollution within our operations.

Pursuant to the Federal Aviation Act, the FAA - with the assistance of the Environmental Protection Agency - is authorized to establish standards governing aircraft noise. Our aircraft fleet complies with current noise standards of the federal aviation regulations. Our international operations are also subject to noise regulations in certain other countries in which we operate.

We are subject to a variety of evolving laws and regulations in the U.S. and abroad regarding privacy, cybersecurity, data protection and data security, including the European Union General Data Protection Regulation and China's Personal Information Protection Law. There has recently been increased regulatory and enforcement focus on data protection in the U.S. (at both the state and federal level) and in other countries.

We are subject to numerous federal, state and local laws and regulations governing employee health and safety, both in the U.S. and in other countries. Compliance with changing laws and regulations from time to time, including those promulgated by the U.S. Occupational Safety and Health Administration and state agencies, could result in materially increased operating costs and capital expenditures, and negatively impact our ability to attract and retain employees.

We maintain websites for business and customer matters at www.ups.com, and for investor relations matters at www.investors.ups.com. Our annual report on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K and any amendments to those reports filed with or furnished to the SEC pursuant to Section 13(a) of the Securities Exchange Act of 1934 are made available free of charge on our investor relations website under the heading "Investors - SEC Filings" as soon as reasonably practical after we electronically file or furnish the reports to the SEC.

Our Code of Business Conduct, which applies to all of our directors, officers and employees, including our principal executive and financial officers, our Corporate Governance Guidelines and the charters for our Audit, Compensation and Human Capital, Risk, and Nominating and Corporate Governance Committees are also available on our investor relations website under the heading "Investors – Sustainability – Governance Documents". In the event that we make changes in, or provide waivers from, the provisions of the Code of Business Conduct that the SEC requires us to disclose, we intend to disclose these events within four business days following the date of the amendment or waiver under that heading on our investor relations website.

We maintain robust economic sanctions compliance procedures designed to promote compliance with applicable sanctions laws. However, it is possible that from time to time we may inadvertently pick up packages from, or deliver packages to, individuals or entities that result in required disclosure under Section 13(r).

As a component of our compliance procedures, from time to time we undertake additional reviews of historical transactions. Based on our most recent review, from August 2018 to the date of this filing, in addition to previously disclosed deliveries we inadvertently delivered to: Bank Melli – 2 shipments (revenue of $18.84, loss of $3.98); the Embassy of Iran (revenue of $7.81, loss of $0.65); Syrian Airlines (revenue of $7.70, profit of $0.72); Irasco SRL – 2 shipments (revenue of $11.59, loss of $1.08); Stark 1 (revenue of $7.33, profit of $2.02); Fanreach (revenue of $9.74, profit of $2.76); and Wael Bazzi (revenue of $4.74, loss of $2.29). The information provided pursuant to Section 13(r) of the Exchange Act in Item 5 of Part II of the Company's Quarterly Report on Form 10-Q for the quarter ended June 30, 2023 is incorporated by reference herein.

Our business, financial condition and results of operations are and will remain subject to numerous risks and uncertainties. You should carefully consider the following risk factors, which may have materially affected or could materially affect us, including impacting our business, financial condition, results of operations, stock price, credit rating or reputation. 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 "Financial Statements and Supplementary Data" in Item 8. These are not the only risks we face. We could also be affected by other unknown events, factors, uncertainties, or risks that we do not currently consider to be material.

We conduct operations in over 200 countries and territories. Our operations are subject to national and international economic factors, as well as the local economic environments in which we operate. Changes in general economic conditions are beyond our control, and it may be difficult for us to adjust our business model. For example, we are affected by industrial production, inflation, unemployment, consumer spending and retail activity levels. We have been, and may in the future be, materially affected by adverse developments in these aspects of the economy. We have also been, and may in the future be, adversely impacted by changes in general economic conditions resulting from geopolitical uncertainty and/or conflicts in or arising from the countries and regions where we operate, including the United Kingdom, the European Union, Ukraine, the Russian Federation, the Middle East and the Trans-Pacific region. Changes in general economic conditions, or our inability to accurately forecast these changes or mitigate the impact of these conditions on our business, could materially adversely affect us.

Our industry continues to rapidly evolve, including demands for faster deliveries, increased visibility into shipments and development of other services. We expect to continue to face significant competition on a local, regional, national and international basis. Competitors include the U.S. and international postal services, various motor carriers, express companies, freight forwarders, air couriers, large transportation and e-commerce companies that continue to make significant investments in their own logistics capabilities, some of whom are currently our customers. We also face competition from start-ups and other smaller companies that combine technologies with flexible labor solutions such as crowdsourcing. New technologies may also create additional sources of competition. Competitors have cost, operational and organizational structures that differ from ours and may offer services or pricing terms that we are not willing to offer. Additionally, from time to time we have raised, and may in the future raise, prices and our customers may not be willing to accept these higher prices. If we do not appropriately respond to competitive pressures, including replacing any lost volume or maintaining our profitability, we could be materially adversely affected.

Transportation market growth may further increase competition. As a result, competitors may improve their financial capacity and strengthen their competitive positions. Business combinations could also result in competitors providing a wider variety of services and products at competitive prices, which could also materially adversely affect us.

For the year ended December 31, 2023, one customer, Amazon.com, Inc. and its affiliates, accounted for 11.8% of our consolidated revenues. Some of our other significant customers can account for a relatively significant portion of our revenues in a particular quarter or year. Customer impact on our revenue and profitability can vary based on a number of factors, including: contractual volume amounts; pricing terms; product launches; e-commerce or other industry trends, including those related to the holiday season; business combinations and the overall growth of a customer's underlying business; as well as any disruptions to their businesses. Customers could choose, and have in the past chosen, to divert all or a portion of their business with us to one of our competitors, demand pricing concessions, request enhanced services that increase our costs, or develop their own logistics capabilities. In addition, certain of our significant customer contracts include termination rights of either party upon the occurrence of certain events or without cause upon advance notice to the other party. If all or a portion of our business relationships with one or more significant customers were to terminate or significantly change, this could materially adversely affect us.

We depend on the skills and continued service of our large workforce. We also regularly hire a large number of part-time and seasonal workers. We must be able to attract, develop and retain a large and diverse global workforce. If we are unable to hire, properly train or retain qualified employees, we could experience higher labor costs, reduced revenues, further increased workers' compensation and automobile liability claims costs, regulatory noncompliance, customer losses and diminution of our brand value or company culture, which could materially adversely affect us. Our ability to control labor costs has in the past been, and is expected to continue to be, subject to numerous factors, including labor-related contractual obligations, turnover, training costs, regulatory changes, market pressures, inflation, unemployment levels and healthcare and other benefit costs.

Many of our U.S. employees are employed under a national master agreement and various supplemental agreements with local unions affiliated with the International Brotherhood of Teamsters (the "Teamsters"). In the third quarter of 2023, a new national master agreement with the Teamsters, which runs through July 31, 2028, was ratified. Our airline pilots, airline mechanics, ground mechanics and certain other employees are employed under other collective bargaining agreements. In addition, some of our international employees are employed under collective bargaining or similar agreements. Other employees may choose to organize in the future. Actual or threatened strikes, work stoppages or slowdowns by our employees could adversely affect our ability to meet our customers' needs. As a result, customers have reduced, and in the future may reduce, their business or stop doing business with us if they believe that such actions or threatened actions may adversely affect our ability to provide services. We may permanently lose customers if we are unable to provide uninterrupted service, and this could materially adversely affect us. The terms of collective bargaining agreements also may affect our competitive position and results of operations. Furthermore, our actions or responses to any such negotiations, labor disputes, strikes or work stoppages could negatively impact how our brand is perceived and our reputation and have adverse effects on our business, including our results of operations.

As a result of concerns about global terrorism and homeland security, various governments have adopted and may adopt additional heightened security requirements, resulting in significantly increased operating costs. Regulatory and legislative requirements may change periodically in response to evolving threats. We cannot determine the effect that any new requirements will have on our operations, cost structure or operating results, and new rules or other future security requirements may significantly increase our operating costs and reduce operating efficiencies. Regardless of our compliance with security requirements or our own security measures, we could also be the target of an attack or security breaches could occur, which could materially adversely affect one or more of our operations, or our business.

We rely on information technology networks and systems and other operational technologies, including the internet and a number of internally-developed systems and applications, as well as certain technology systems from third-party vendors (collectively referred to as "IT") to operate our business. For example, we rely on these technologies to receive package level information in advance of the physical receipt of packages, to move and track packages through our operations, to efficiently plan deliveries, to execute billing processes, and to track and report financial and operational data. Our franchise locations and subsidiaries also rely on IT systems to manage their business processes and activities.

IT and other systems (ours, as well as those of our franchisees, acquired businesses, and third-party service providers) have been and will continue in the future to be susceptible to damage, disruptions and shutdowns due to programming errors, defects or other vulnerabilities, power outages, hardware failures, misconfigurations, computer viruses, cyber-attacks, encryption caused by ransomware or malware attacks, exfiltration of data, attacks by foreign governments, state-sponsored actors, or criminal groups, theft, misconduct by employees or other insiders, telecommunications failures, misuse, human errors or other catastrophic events. In recent periods, the frequency and sophistication of cyber-attacks have increased and are expected to continue to increase, including as a result of state-sponsored cybersecurity attacks during periods of geopolitical conflict, such as the ongoing conflicts in Ukraine and the Middle East. In addition, the rapid evolution and increased adoption of artificial intelligence technologies may intensify our cybersecurity risks. Accordingly, we may be unable to anticipate these techniques or to implement adequate measures to recognize, detect or prevent the occurrence of any of the events described

above. In addition, our security processes, protocols and standards may not prove to be sufficient, effective or may not be complied with, either intentionally or inadvertently. To date, we have not experienced a material cybersecurity incident. However, cybersecurity incidents have in the past and may in the future expose us, our customers, franchisees, service providers or others, to loss, disclosure or misuse of proprietary information and sensitive or confidential data or result in disruptions to our operations or those of our customers, franchisees, service providers or others. For example, cyber criminals have in the past gained access, and are expected to continue to try to gain access to customer accounts. The type of activity includes fraudulently diverting and misappropriating items being transported in our network, fraudulently charging shipment fees to customer or franchisee accounts, and fraudulently sending text messages to recipients purporting to be from UPS. The occurrence of any of the events described above could result in material disruptions in our business, the loss of existing or potential customers, damage to our brand and reputation, additional regulatory scrutiny, litigation and other potential material liability. We also may not discover the occurrence of any of the events described above for a significant period of time after the event occurs.

We utilize and interact with the IT networks and systems of third parties for many aspects of our business, including related to our customers, franchisees and service providers such as cloud service providers and third-party delivery services. These third parties have access to information we maintain about our company, operations, customers, employees and vendors, or operating systems that are critical to or can significantly impact our business operations. These third parties are subject to risks described above, and other risks, that could damage, disrupt or close down their networks or systems. Security processes, protocols and standards that we implement and contractual provisions requiring security measures that we impose on such third parties may not be sufficient or effective at preventing such events or may not be adhered to. These events have in the past and could in the future result in unauthorized access to, or disruptions or denials of access to, misuse or disclosure of, information or systems that are important to us, including proprietary information, sensitive or confidential data, and other information about our operations, customers, employees and suppliers, including personal information.

We have invested and expect to continue to invest in IT security initiatives, IT risk management and disaster recovery capabilities. The costs and operational consequences of implementing, maintaining and enhancing further data or system protection measures could increase significantly to overcome increasingly frequent, complex and sophisticated cyber threats and regulatory requirements.

In addition, our customers’ confidence in our ability to protect data and systems and to provide services consistent with their expectations could be impacted, further disrupting our operations. While we maintain cyber insurance, we cannot be certain that our coverage will be adequate for liabilities actually incurred, that insurance will continue to be available to us on economically reasonable terms, or at all, or that any insurer will not deny coverage as to any future claim.

Although to date we are unaware of any material data breach or cybersecurity incident, including an information system disruption, we cannot provide any assurances that such material events and impacts will not occur in the future. Our efforts to deter, identify, mitigate and/or eliminate future breaches or cybersecurity incidents may require significant additional effort and expense and may not be successful.

In addition, there has recently been heightened regulatory and enforcement focus relating to the collection, use, retention, transfer, and processing of personal data in the U.S. (at both the state and federal level) and internationally, including the EU’s General Data Protection Regulation, the California Privacy Rights Act, the Virginia Consumer Data Protection Act, and other similar laws that have been or are expected to be enacted by other jurisdictions. In addition, China and certain other jurisdictions have enacted more stringent data localization requirements. An actual or alleged failure to comply with applicable data protection laws, regulations, or other data protection standards has in the past and may in the future expose us to litigation, fines, sanctions, or other penalties, which could harm our reputation and adversely affect our business, results of operations, and financial condition. The regulatory environment is increasingly challenging, based on discretionary factors, and difficult to predict. Consequently, compliance with applicable regulations in the various jurisdictions in which we do business may present material obligations and risks to our business, including significantly expanded compliance burdens, costs, and enforcement risks which are expected to increase over time; require us to make extensive system or operational changes; or adversely affect the cost or attractiveness of the services we offer.

Our success depends in part on our ability to maintain the image of the UPS brand and our reputation. Service quality issues, actual or perceived, could tarnish the image of our brand and may cause customers not to use UPS services. Also, adverse publicity or public sentiment surrounding labor relations, environmental, sustainability and governance concerns, physical or cyber security matters, political activities and similar matters, or attempts to connect our company to such issues, either in the U.S. or elsewhere, could materially adversely affect us. For example, damage to our reputation or loss of brand equity could require the allocation of resources to rebuild our reputation and restore the value of our brand. The proliferation of social media may increase the likelihood, speed, and magnitude of negative brand events.

The effects of climate change present financial and operational risks to our business, both directly and indirectly. We have made public statements regarding our intended reduction of carbon emissions, including our goal to achieve carbon neutrality in our global operations by 2050 and our other short- and mid-term environmental sustainability goals.

Our ability to meet our goals will depend in part on significant technological advancements with respect to the development and availability of reliable, affordable and sustainable alternative solutions that are outside of our control, including sustainable aviation fuel and alternative fuel vehicles. While we remain committed to being responsive to the effects of climate change and reducing our carbon footprint, there can be no assurances that our goals and strategic plans to achieve those goals will be successful, that the costs related to climate transition will not be higher than expected, that the necessary technological advancements will occur in the timeframe we expect, or at all, that the severity of and or the pace of negative climate-related effects will not accelerate faster than expected, or that proposed regulation or deregulation related to climate change will not have a negative competitive impact, any one of which could have a material adverse effect on our capital expenditures or other expenses, revenue or results of operations.

Furthermore, methodologies for reporting climate-related information may change and previously reported information may be adjusted to reflect new reporting protocols or regulations, improvements in the availability and quality of third-party data, changing assumptions, changes in the nature and scope of our operations and other changes in circumstances. Our processes and controls for reporting climate-related information across our operations are evolving along with multiple disparate standards for identifying, measuring and reporting sustainability metrics, including disclosures that may be required by the SEC, European and other regulators, and such standards may change over time, which could result in significant revisions to our current goals, reported progress in achieving such goals, or our ability to achieve such goals in the future. Changes in regulation or technology impacting our business could require us to write down the carrying value of assets, which could result in material impairment charges.

Moreover, we may determine that it is in our best interests to prioritize other business, social, governance or sustainable investments over the achievement of our current goals based on economic, regulatory or social factors, business strategy or other factors. If we do not meet these goals or there is perception that we failed to meet these goals, then, in addition to regulatory and legal risks related to compliance, we could incur adverse publicity and reaction, which could adversely impact our reputation, and in turn adversely impact our results of operations.

Weather conditions or other natural or man-made disasters and the increased severity or frequency thereof (including as a result of climate change), including storms, floods, fires, earthquakes, rising temperatures, epidemics, pandemics, conflicts, civil or political unrest, or terrorist attacks, have in the past and may in the future disrupt our business. Customers may reduce shipments, supply chains may be disrupted, demand may be negatively impacted or our costs to operate our business may increase, any of which could have a material adverse effect on us. Any such event affecting one of our major facilities could result in a significant interruption in or disruption of our business. A potential result of climate change is more frequent or more severe weather events or natural disasters. To the extent such weather events or natural disasters do become more frequent or severe, disruptions to our business and those of our customers and costs to repair damaged facilities or maintain or resume operations could increase. Furthermore, climate change may reduce the availability or increase the cost of insurance for these negative impacts of natural disasters and adverse weather conditions by contributing to an increase in the incidence and severity of such natural disasters.

We have significant international operations and, as a result, we are exposed to changing economic, political and social developments in a number of countries, all of which are beyond our control. Emerging markets are often more volatile than those in other countries, and any broad-based downturn in these markets could reduce our revenues and materially adversely affect our business, financial condition and results of operations. We are subject to many laws governing our international operations, including those that prohibit improper payments to government officials and commercial customers, govern our environmental impact or labor matters, and restrict where we can do business, our shipments to certain countries and the information that we can provide to non-U.S. governments. Our failure to manage and anticipate these and other risks associated with our international operations could materially adversely affect us.

From time to time we acquire businesses, form joint ventures and strategic alliances, and dispose of operations. Whether we realize the anticipated benefits from these transactions depends, in part, upon successful integration between the businesses involved, the performance of the underlying operations, capabilities or technologies and the management of the acquired operations. Accordingly, our financial results could be materially adversely affected by our failure to effectively integrate acquired operations, unanticipated performance or other issues or transaction-related charges.

Fuel and energy costs have a significant impact on our operations. We require significant quantities of fuel for our aircraft and delivery vehicles and are exposed to the risks associated with variations in the market price for petroleum products, including gasoline, diesel and jet fuel. We seek to mitigate our exposure to changing fuel prices through our pricing strategy and may utilize hedging transactions from time to time. There can be no assurance that this strategy will be effective. If we are unable to maintain or increase our fuel surcharges, higher fuel costs could materially adversely impact our operating results. Even if we are able to offset changes in fuel costs with surcharges, high fuel surcharges have in the past, and may in the future result in a shift from our higher-yielding products to lower-yielding products or an overall reduction in volume, revenue and profitability. Moreover, we could experience a disruption in energy supplies as a result of new or increased regulation, war or other conflicts, weather-related events or natural disasters, actions by producers (including as part of their own sustainability efforts) or other factors beyond our control, which could have a material adverse effect on us.

We conduct business in a number of countries, with a significant portion of our revenue derived from operations outside the United States. Our international operations are affected by changes in the exchange rates for local currencies, in particular the Euro, British Pound Sterling, Canadian Dollar, Chinese Renminbi and Hong Kong 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. Additionally, changes in interest rates impact the valuation of our pension and postretirement benefit obligations and the related costs recognized in the statements of consolidated income. The impact of changes in interest rates on our pension and postretirement benefit obligations and costs, and on our debt, is discussed further in Part I, "Item 7 - Critical Accounting Estimates," and Part II, "Item 7A - Quantitative and Qualitative Disclosures about Market Risk", respectively, of this report.

We monitor and manage foreign currency exchange rate and interest rate exposures, and use derivative instruments to mitigate the impact of changes in these rates on our financial condition and results of operations; however, changes in foreign currency exchange rates and interest rates cannot always be predicted or effectively hedged, and may have a material adverse effect on us.

Our business requires significant capital investments, including in aircraft, vehicles, technology, facilities and sortation and other equipment. In addition to forecasting our capital investment requirements, we adjust other elements of our operations and cost structure in response to economic and regulatory conditions. These investments support both our existing business and anticipated growth. Forecasting amounts, types and timing of investments involves many factors which are subject to uncertainty and may be beyond our control, such as general economic trends, revenues, profitability, changes in governmental regulation and competition. If we do not accurately forecast our future capital investment needs, we could under- or over-invest, or have excess capacity or insufficient capacity, any of which could negatively affect our revenues and profitability.

Our employee health, retiree health and pension benefit expenses are significant. In recent years, we have experienced increases in some of these costs, in particular, ongoing increases in healthcare costs in excess of the rate of inflation and historically low discount rates that we use to value our company-sponsored defined benefit plan obligations. Increasing healthcare 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 materially adversely affect our business, financial condition, or results of operations, and have required, and may in the future require significant contributions to our benefit plans. Our national master agreement with the Teamsters includes provisions that are designed to mitigate certain healthcare expenses, but there can be no assurance that our efforts will be successful or that these efforts will not materially adversely affect us.

We participate in various trustee-managed multiemployer pension and health and welfare plans for employees covered under collective bargaining agreements. As part of the overall collective bargaining process for wage and benefit levels, we have agreed to contribute certain amounts to the multiemployer benefit plans during the contract period. The multiemployer benefit plans set benefit levels and are responsible for benefit delivery to participants. Future contribution amounts to multiemployer benefit plans will be determined through collective bargaining. However, in future collective bargaining negotiations, we could agree to make significantly higher future contributions to one or more of these plans. At this time, we are unable to determine the amount of additional future contributions, if any, or whether any material adverse effect on us could result from our participation in these plans.

In addition to our ongoing multiemployer pension plan obligations, we may have an obligation in the future to pay significant coordinating benefits previously earned by UPS employees in the Central States Pension Fund (the "CSPF"). For additional information on our potential liabilities related to the CSPF, see note 5 to the audited, consolidated financial statements.

We have a combination of both self-insurance and high-deductible insurance programs for the risks arising out of our business and operations, including claims exposure resulting from cargo loss, personal injury, property damage, aircraft and related liabilities, business interruption and workers' compensation. Self-insured 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, severity or cost of claims for which we retain risk continues to increase, our financial condition and results of operations could be materially adversely affected. If we lose our ability to, or decide not to, self-insure these risks, our insurance cost could materially increase and we may find it difficult to obtain adequate levels of insurance coverage.

We regularly assess the carrying values of our assets relative to their estimated fair values. If the carrying value of an asset exceeds its estimated fair value, we may be required to incur charges to reduce the carrying value thereof. The determination of fair value is dependent on a significant number of estimates and assumptions that could be impacted by a variety of factors, including changes in business strategy, revenue, expenses, government regulations, including regulation related to climate change, costs of capital and economic or market conditions. The use of different estimates or assumptions could also result in different estimates of fair value. Our estimates of fair value have resulted from time to time, and may in the future result, in substantial impairments of our assets. For example, during the year ended December 31, 2023, as a result of a number of factors including changes in business strategy and challenging macroeconomic conditions such as increases in the risk-free interest rate and volatility of the stock prices of market comparables, we incurred impairment charges of $125 and $111 million in respect of goodwill and indefinite-lived intangible assets, respectively. In addition, we have been and may be required in the future to recognize increased depreciation and amortization charges if we determine the useful lives or salvage values of our assets are less than we originally estimated. Such changes have in the past, and may in the future, reduce our net income.

We are regularly under audit by tax authorities in many jurisdictions. Economic and political pressures to increase tax revenue may make resolving tax disputes more difficult. The final determination of tax audits and any related litigation could be materially different from our historical income tax provisions and accruals. In addition, changes in U.S. federal and state or international tax laws, other fundamental law changes currently being considered by many countries, and changes in taxing jurisdictions’ administrative interpretations, decisions, policies and positions may materially adversely impact our tax expense and cash flows.

We are subject to complex and stringent aviation, transportation, environmental, security, labor, employment, safety, privacy, disclosure and data protection and other governmental laws, regulations and policies, both in the U.S. and internationally. In addition, we are impacted by laws, regulations and policies that affect global trade, including tariff and trade policies, export requirements, embargoes, sanctions, taxes, monetary policies and other restrictions and charges. Trade discussions and arrangements between the U.S. and various of its trading partners are fluid, and existing and future trade agreements are, and are expected to continue to be, subject to a number of uncertainties, including the imposition of new tariffs or adjustments and changes to the products covered by existing tariffs. The impact of new laws, regulations and policies or decisions or interpretations by authorities applying those laws and regulations, cannot be predicted. Compliance with any new laws, regulations or policies may increase our operating costs or require significant capital expenditures. Any failure to comply with applicable laws, regulations or policies in the U.S. or other countries could result in substantial fines or possible revocation of our authority to conduct our operations, which could materially adversely affect us.

Regulation and required disclosures of greenhouse gas ("GHG") emissions and related matters exposes us to potentially significant new taxes, fees, disclosure and compliance obligations and other costs. Compliance with such regulation, and any increased or additional regulation, or the associated costs is further complicated by the fact that various countries and regions may adopt different approaches to climate change regulation and disclosures.

For example, the Carbon Offsetting and Reduction Scheme for International Aviation ("CORSIA"), a global, market-based emissions offset program to encourage carbon-neutral growth began a voluntary pilot phase in 2021, with mandatory participation scheduled to begin in 2027. The International Civil Aviation Organization, which adopted CORSIA, continues to develop details regarding implementation, but compliance with CORSIA is expected to increase our operating costs, potentially significantly.

In the U.S., Congress has considered but, to date, not passed various bills that would regulate GHG emissions. Nevertheless, we believe some form of federal climate change legislation is possible in the future. Even in the absence of such legislation, the Environmental Protection Agency could determine to regulate GHG emissions, especially aircraft or diesel engine emissions, and this could impose substantial costs on us.

Increased regulation relating to GHG emissions in the U.S. or abroad, especially aircraft or diesel engine emissions, could, among other things, increase the cost of fuel and other energy we purchase and the capital costs associated with updating or replacing our aircraft or vehicles prematurely. We cannot predict the impact any future regulation will have on our cost structure or our operating results. It is likely that such regulation could significantly increase our operating costs and that we may not be willing or able to pass such costs along to our customers. Moreover, even without such 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.

Furthermore, many countries, as well as U.S. states, in which we operate or are subject to regulation have adopted, or are expected to adopt, additional requirements relating to the disclosure of GHG emissions and related matters. In many cases these requirements differ and may conflict from country to country. Compliance with these disclosure requirements may increase our operating costs or require significant management time and attention. Any failure to comply with applicable disclosure regulations in the U.S. (at either the federal or state level) or other countries could result in substantial fines or other penalties, which could materially adversely affect us.

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 result in significant expenditures and have a material adverse effect on us.

The Board regularly discusses our most significant risks and how these risks are being managed. The Board has appointed a Risk Committee, consisting entirely of independent directors, whose responsibilities include assisting the Board in overseeing management’s identification and evaluation of strategic enterprise risks, including risks associated with privacy, technology, information security, cybersecurity and cyber incident response and business continuity. The Risk Committee regularly updates the Board on these activities.

The Risk Committee oversees the Company’s approach to cybersecurity risk assessment and mitigation by, among other things, (i) reviewing the Company’s cybersecurity insurance program, (ii) reviewing the Company’s cybersecurity budget, (iii) discussing the results of various internal cybersecurity audits and periodic independent third-party assessments of the Company’s cybersecurity programs, (iv) being briefed on cybersecurity matters by outside experts, and (v) receiving regular updates from the Company’s Chief Information Security Officer (“CISO”) and others on cybersecurity risks, operational metrics, compliance and regulatory developments, training programs, risk mitigation activities, key projects and industry developments. The Company's Chief Legal and Compliance Officer ("CLCO"), Chief Digital and Technology Officer ("CDTO"), CISO and Vice President of Compliance and Internal Audit participate in Risk Committee meetings and meet individually with the Risk Committee on a periodic basis to discuss and address relevant matters, including the Company’s approach to cybersecurity risk assessment and mitigation. The CISO reports to the CDTO, who in turn reports to the Chief Executive Officer ("CEO"). The CISO has more than thirty years of IT experience, has served many years in various information security management roles and has multiple cybersecurity certifications.

The Company maintains an enterprise risk management process designed to identify potential events that may affect the achievement of the Company's objectives or have a material adverse effect on the Company. Cybersecurity is among the risks considered as a part of this process. The Company's management, including the CISO, also participates on the Company's Information Security & Privacy Governance Council (“ISPGC”). The ISPGC meets periodically to consider information security and privacy matters.

The Company utilizes various technical and qualitative processes to assist in identifying, assessing and managing cybersecurity risks. The Company's processes include periodic discussions and risk reviews with management and, depending on facts and circumstances, may include internal audits, third-party assessments, post-remediation reviews, engagements with independent third-party service providers and key governmental agencies, regular employee training, an incident response plan and backup and recovery plans. Our periodic engagements with independent third-party service providers are designed to provide qualitative and technical cybersecurity assessments. The Company has a corporate-level cybersecurity team, led by the CISO, that, among other responsibilities, receives and reviews reports regarding potential threats, trends and remediation strategies. The cybersecurity team evaluates threat intelligence and information obtained from various sources, including internal, public or private sources, government agencies and external consultants. Certain of the Company's subsidiaries have separate cybersecurity teams that, along with the corporate-level cybersecurity team, play a role in the Company's efforts to monitor, identify, assess and manage cybersecurity risks.

We interact with the information technology networks and systems of third parties for many aspects of our business. We consider and evaluate cybersecurity risks associated with the use of independent third-party service providers. To help UPS understand and mitigate potential cybersecurity risks, we generally utilize measures such as vendor risk assessments, periodic technical assessments of third-party vendors' controls and contracts governing the use of and access to our data and compliance with our security requirements.

We maintain an Incident Response Plan that includes processes and procedures for reviewing and responding to cybersecurity incidents. We periodically test our readiness to respond to a cybersecurity incident through various scenario-based drills. The Incident Response Plan includes processes for escalation to the CISO, the Executive Leadership Team, including the CEO, the Risk Committee and the Board, and a process for consideration of whether a cybersecurity incident is material and may require disclosure in SEC filings.

For additional information on cybersecurity risks and the impact they may have on our business strategy, results of operations or financial condition see "Risk Factors – Business and Operating Risks – A significant cybersecurity incident, or increased data protection regulations, could materially adversely affect us".

We own or lease over 1,000 package operating facilities in the U.S., with approximately 90 million square feet of floor space. These facilities have vehicles and drivers stationed for the pickup and delivery of packages, and capacity to sort and transfer packages. Our larger facilities also service our vehicles and equipment, and employ specialized mechanical equipment for the sorting and handling of packages. We own or lease approximately 800 facilities in our international package operations, with approximately 21 million square feet of floor space.

We own or lease more than 600 facilities, with approximately 46 million square feet of floor space, which support our freight forwarding and logistics operations. This includes approximately 17 million square feet of healthcare-compliant warehousing. We own and operate a logistics campus consisting of approximately 4 million square feet in Louisville, Kentucky.

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. Our class B common stock is listed on the New York Stock Exchange under the symbol “UPS”.

In January 2023, the Board of Directors terminated this authorization and approved a new share repurchase authorization for $5.0 billion of class A and class B common stock. During the year ended December 31, 2023, we repurchased 12.3 million shares of class B common stock for $2.2 billion under this authorization. We did not repurchase any shares during the fourth quarter of 2023 and do not anticipate repurchasing any shares in 2024. As of December 31, 2023, we had $2.8 billion available under our share repurchase authorization.

The following performance graph and related information shall not be deemed “soliciting material” or to be “filed” with the SEC, nor shall such information be incorporated by reference into any future filing under the Securities Act of 1933 or Securities Exchange Act of 1934, each as amended, except to the extent that the Company specifically incorporates such information by reference into such filing.

The following graph shows a five-year comparison of cumulative total shareowners’ returns for our class B common stock, the Standard & Poor’s 500 Index and the Dow Jones Transportation Average. The comparison of the total cumulative return on investment, which is the change in the stock price plus reinvested dividends for each of the quarterly periods, assumes that $100 was invested on December 31, 2018 in the Standard & Poor’s 500 Index, the Dow Jones Transportation Average and our class B common stock.

We continue to focus on executing our strategy of Customer First, People Led and Innovation Driven by making it quicker and easier for customers to do business with us. We continue to enhance customer engagement through combining our network with digital capabilities and to invest in the most attractive parts of the market, including healthcare, Asia trade lanes and small- and medium-sized businesses ("SMBs").

In furtherance of our strategy, during 2023 we acquired MNX Global Logistics, a global time-critical and temperature-sensitive logistics provider, and Happy Returns, a technology-focused company that provides innovative end-to-end return services. We opened our state-of-the-art UPS Velocity fulfillment center in the U.S. and announced plans to build a new air hub in Hong Kong. These initiatives, together with continued growth in our Digital Access Program and deployment of our Smart Package Smart Facility technology within U.S. small package operations, are intended to allow us to reach new markets and customers, and better serve our current customer base.

During the year, macroeconomic headwinds, including inflationary pressures and changes in consumer behavior, together with volume diversion resulting from our labor negotiations with the International Brotherhood of Teamsters ("Teamsters"), contributed to volume declines in our U.S. small package business. Internationally, the challenging macroeconomic environment, coupled with geopolitical tensions, drove a decline in demand for our small package services in Europe and Asia. Our freight forwarding businesses, including truckload brokerage, were negatively impacted by soft demand and market overcapacity. We expect global economic conditions to improve gradually during 2024, and therefore expect volume and revenue growth to increase in the second half of the year.

In the third quarter of 2023, our Teamsters employees ratified a new national master agreement. Under the agreement, wage and benefit rates, combined with all other contract provisions, will increase union cost at a 3.3% compounded annual growth rate over the five-year term of the contract, with the majority of the increase in the first and fifth years. We experienced higher year-over-year labor costs in the second half of the year as a result of these contractual increases, which we expect to persist through the first half of 2024.

Faced with a challenging external environment, we remain focused on our strategy. We are taking action intended to right-size our business for the future and focus on key enablers of growth. These moves include exploring strategic alternatives for our truckload brokerage business and reducing headcount through our "fit to serve" initiative to create a more efficient operating model and enhance responsiveness to changing market dynamics.

Highlights of our results for the years ended December 31, 2023 and 2022, which are discussed in more detail in the sections that follow, include:

•Revenue and average daily package volume in our global small package operations decreased for the year, with declines in both commercial and residential shipments across all of our products. These declines were primarily the result of the macroeconomic conditions and union labor-related uncertainties described above, as well as reductions in fuel and demand-related surcharges.

•Operating expenses decreased for the year, driven by a reduction in purchased transportation in Supply Chain Solutions and reductions in fuel expense in our small package operations, as well as the impact of our ongoing productivity initiatives and reductions in operating costs; these reductions were partially offset by U.S. Domestic Package segment wage rate increases in the second half of 2023 due to the new Teamsters contract.

In the U.S. Domestic Package segment, revenue declines for the year were driven by lower volume, a shift in product mix, and lower fuel and demand-related surcharges. These were somewhat offset by revenue per piece growth due to increases in base rates and changes in customer mix. Expenses decreased for the year, primarily due to declines in fuel prices and reductions in purchased transportation. Higher direct union labor costs were offset by a reduction in hours and lower management compensation expense.

In our International Package segment, revenue declines for the year were driven by lower volume and declines in fuel and demand-related surcharges. These were partially offset by the impact of base rate increases. Expenses decreased year over year, driven by lower fuel and third-party transportation expense as a result of volume declines and lower fuel prices.

Adjusted financial measures should be considered in addition to, and not as an alternative for, our reported results prepared in accordance with GAAP. Our adjusted financial measures do not represent a comprehensive basis of accounting and therefore may not be comparable to similarly titled measures reported by other companies.

The income tax impacts of these items are calculated by multiplying the statutory tax rates applicable in each tax jurisdiction, including the U.S. federal jurisdiction and various U.S. state and non-U.S. jurisdictions, by the tax-deductible adjustments. The blended average effective income tax rates for the years ended December 31, 2023 and 2022 were 22.5% and 26.5%, respectively.

During 2023, we made a one-time payment to certain U.S.-based, non-union part-time supervisors following the ratification of our labor agreement with the Teamsters. We do not expect this or similar payments to recur. We supplement the presentation of our operating profit, operating margin, income before income taxes, net income and earnings per share with non-GAAP measures that exclude the impact of this payment. We believe excluding the impact of this one-time payment better enables users of our financial statements to view and evaluate underlying business performance from the same perspective as management.

We supplement the presentation of our operating profit, operating margin, income before income taxes, net income and earnings per share with non-GAAP measures that exclude the impact of charges related to transformation activities, and goodwill and asset impairment charges. We believe excluding the impact of these charges better enables users of our financial statements to view and evaluate underlying business performance from the perspective of management. We do not consider these costs when evaluating the operating performance of our business units, making decisions to allocate resources or in determining incentive compensation awards. For more information regarding transformation activities, see note 18 to the audited, consolidated financial statements. For more information regarding goodwill and asset impairment charges, see note 1 and note 7.

During 2022, we completed certain structural changes to the design of our incentive compensation programs that resulted in a one-time, non-cash charge in connection with the accelerated vesting of certain equity incentive awards that we do not expect to repeat. We supplement the presentation of our operating profit, operating margin, income before income taxes, net income and earnings per share with non-GAAP measures that exclude the impact of these changes. We believe excluding the impacts of such changes allows users of our financial statements to identify underlying growth trends in compensation and benefits expense. For more information regarding incentive compensation program design changes, see note 13 to the audited, consolidated financial statements.

During 2022, we determined to retire six of our existing MD-11 aircraft from operational use in 2023. In connection therewith, we reduced the estimated residual value of our MD-11 fleet, incurring a one-time, non-cash charge on our fully-depreciated aircraft. This charge was allocated between our U.S. Domestic Package and International Package segments. We supplement the presentation of our operating profit, operating margin, income before income taxes, net income and earnings per share with non-GAAP measures that exclude the impact of this charge. We believe excluding the impact of this charge better enables users of our financial statements to understand the ongoing cost associated with our long-lived assets. For more information regarding residual values, see note 4 to the audited, consolidated financial statements.

We supplement the reporting of revenue, revenue per piece and operating profit with adjusted measures that exclude the period over period impact of foreign currency exchange rate changes and hedging activities. We believe currency-neutral revenue, revenue per piece and operating profit information allows users of our financial statements to understand growth trends in our products and results. We evaluate the performance of International Package and Supply Chain Solutions on this currency-neutral basis.

Currency-neutral revenue, revenue per piece and operating profit are calculated by dividing current period reported U.S. Dollar revenue, revenue per piece and operating profit by the current period average exchange rates to derive current period local currency revenue, revenue per piece and operating profit. The derived amounts are then multiplied by the average foreign currency exchange rates used to translate the comparable results for each month in the prior year period (including the period over period impact of foreign currency hedging activities). The difference between the current period reported U.S. Dollar revenue, revenue per piece and operating profit and the derived current period U.S. Dollar revenue, revenue per piece and operating profit is the period-over-period impact of currency fluctuations.

We incur certain employment-related expenses associated with pension and postretirement medical benefits. These pension and postretirement medical benefits costs for company-sponsored defined benefit plans are calculated using various actuarial assumptions and methodologies, including discount rates, expected returns on plan assets, healthcare cost trend rates, inflation, compensation increase rates, mortality rates and coordination of benefits with plans not sponsored by UPS. Actuarial assumptions are reviewed on an annual basis, unless circumstances require an interim remeasurement of any of our plans.

We recognize changes in the fair value of plan assets and net actuarial gains and losses in excess of a 10% corridor (defined as 10% of the greater of the fair value of plan assets or the plan's projected benefit obligation), as well as gains and losses resulting from plan curtailments and settlements, for our defined benefit pension and postretirement medical plans immediately as part of Investment income and other in the statements of consolidated income. We supplement the presentation of our income before income taxes, net income and earnings per share with adjusted measures that exclude the impact of these gains and losses and the related income tax effects. We believe excluding these defined benefit pension and postretirement medical plan gains and losses provides important supplemental information by removing the volatility associated with plan amendments and short-term changes in market interest rates, equity values and similar factors.

The remeasurement of our defined benefit pension and postretirement medical plans' assets and liabilities resulted in a loss of $0.4 billion and a gain of $1.1 billion for the years ended December 31, 2023 and 2022, respectively. The table below shows the amounts associated with each component of the loss and gain, as well as the weighted-average actuarial assumptions used to determine our net periodic benefit cost, for each year:
