1 PURPOSE
eBay is committed to the responsible use of Artificial Intelligence (AI). This Policy outlines our core
Responsible AI principles, which are the foundation of our Responsible AI approach and theguideposts for all development, deployment, and use of AI at eBay.
Our Responsible AI approach is risk-based, the criticality and applicability of each principle being
dependent on how and for what purpose each AI system is being used. For example, using Natural
Language Processing (NLP) to support internal data processing presents a distinct set of risks fromusing the same technology to flag suspicious customer activity. These contextual considerations arepart of the operationalization of this Policy, as described separately by the Standard and Guidelines
documents (see below). Furthermore, the Responsible AI principles can overlap and even impact
each other, such that tradeoffs may be needed to balance for the need for transparency with ensuring
security and privacy.
The Responsible AI principles delineated in this Policy will be operationalized through theResponsible AI Standard, which establishes accountability for adherence to this Policy, and theResponsible AI Guidelines, which describe the specific outcomes and implementation requirementsthat will enable compliance with this Policy and the Responsible AI Standard.

1CorporateGovernanceAI technology is evolving rapidly. Consequently, this Policy will be updated, as needed, to remain up
to date with new laws and new learnings, technologies, and best practices from within and outside thecompany.

2 SCOPE
Definition. There is currently still no universally accepted definition of AI. We have adopted the definitionof an AI system set forth in the proposed EU AI Act, i.e.:“a machine-based system that is designed to operate with varying levels of autonomy and thatcan, for explicit or implicit objectives, generate outputs such as predictions, recommendations, ordecisions that influence physical or virtual environments.”
Subject. This Policy applies to eBay Inc. and its subsidiaries (collectively, “eBay”), eBay personnel(including employees and contractors), and eBay systems. eBay will expect our vendors to adhere
through our Supplier Code of Business Conduct & Ethics.
Application. AI systems should be governed across their entire lifecycle, from research and design todecommission. As such, this Policy applies to all phases of AI development and use. It applies both tointernal-facing and customer-facing applications.
Compliance. Compliance with this Policy is required and the responsibility of each eBay employee. eBay
will implement internal governance structures and measures to ensure that AI systems perform to thehigh standards set forth herein, satisfy internal and external expectations, identify, and mitigate potential
negative impacts, and more generally to ensure compliance with this Policy. This Policy will be owned bythe Responsible AI Committee and maintained by the Office of Responsible AI.

3.1

Policy Statement

eBay’s Responsible AI principles are set forth below. These are five high-level, complex principles thatencompass more singularly focused subprinciples. Those subprinciples have been called out explicitly
where applicable.

Reliability, Safety, and Security: Build trustworthy AI systems that are reliable,safe, and secure
eBay’s AI systems should be designed and developed to prevent unauthorized access, malicious use,and protection measures for any confidential data that are used to train or operate AI systems andmodels within eBay. They should be designed to perform as they were originally intended, to respondsecurely in conditions of normal use, foreseeable use, to not pose unreasonable safety risks in
unexpected situations or adverse conditions, and to be secure and resilient, in accordance with eBay’s
Information Security Policy.

Governance•Reliability: eBay’s AI systems must be reliable to be trusted. Every AI system should
consistently produce the expected outcome and task they are designed for across various
conditions in a way that minimizes unpredictability and eBay should ensure appropriate testing
and refining of the AI System.

•Safety: The safety of eBay employees, customers and stakeholders is paramount. eBay shouldensure its AI systems do not cause harm or unintended consequences and eBay should conduct
regular assessments to identify and rectify any issues that affect the safety of the AI system.

•Security: eBay’s AI systems should be secure and protected from unauthorized access,tampering and any other form of malicious intervention. eBay recognizes that AI technology
comes with unique security risks that require constant attention to stay ahead of risks. We arecommitted to implementing state-of-the-art technical and organizational techniques andmeasures, including compliance with guidelines and requirements developed by standards
bodies, to ensure protection from present and future threats.

Inclusivity, Equity, and Fairness: Strive to enable equitable and fair AI
experiences
Building with an inclusivity mindset moves us closer to achieving equity and fairness. We strive to ensure
our AI systems represent a diverse range of human cultures, backgrounds, and experiences. Inclusivity inAI systems means implementing appropriate measures to avoid excluding certain groups or people frombeing able to engage with or to benefit from the AI system. Such measures can include ensuring diverse
and representative datasets are used in the AI system’s training, fine-tuning, and evaluation, and enabling
accessibility by ensuring that the way individuals engage with the AI system accounts for visual, hearing,and other impairments (e.g., through speech-to-text, text-to-speech technologies).
We are putting processes in place to ensure that AI systems will not harm or deceive people, and theiruse should never lead to unfair biases or unjust impacts. Key checks and balances help ensure that an AI
system’s decisions do not unfairly discriminate against an individual, group, or community based on age,gender, race, sexual orientation, religion, or other protected characteristics. We strive to ensure thatdatasets we use are accurate, relevant, representative, of verifiable origin, and fit-for-purpose.

Accountability and Lawfulness: Everyone in the eBay community has a role toplay in responsible AIWe take steps to ensure that AI systems function properly, throughout their lifecycle, and that theirdesign, development, testing, and use in deployment comply with applicable regulatory frameworks. We
actively ensure there is human oversight throughout the development, launch and monitoring of AI uses,
and have implemented risk-based decision-making processes (for example, by providing documentation
on key decisions throughout the AI system lifecycle and conducting or allowing auditing where justified).
We encourage the use of appropriate documentation concerning the development, implementation,deployment, onboarding, and oversight of our AI systems.

Privacy by Design: Build AI systems with privacy at the forefront
To the extent personal information is involved, eBay’s Privacy principles – which are the backbone ofeBay’s Privacy program – should guide choices for AI system design, development, deployment, and use.
This includes ensuring a Privacy by Design approach, data minimization, data quality, and purpose
specification.

Transparency: Provide users with transparency into our use of AI
Recent classes of AI technologies, such as Generative AI, make it difficult to understand the reasoning
behind an AI system’s output. eBay strives to be transparent to end-users about its use of AI. Thistransparency will be accomplished in some cases by disclosing within the experience itself information
about the type of AI being used, and in other cases, through broader disclosure of our use of AI generally,as is contextually appropriate based on stage of its lifecycle. Our transparency approaches will also strive
to communicate most effectively given the role of the individuals interacting with or using the AI system.
