Introduction Financial managers of the various entities within ERIE hold an important and elevated role in corporate governance. They are empowered to ensure that stakeholders’ interests are appropriately balanced, protected and preserved. In addition to being subject to ERIE’s “Code of Conduct”, ERIE’s Chief Executive Officer, Chief Financial Officer (“CFO”), Controller and other persons performing similar functions (referred to as the “Financial Officers”), are bound by this Code of Ethics for CEO and Senior Financial Officers. The Financial Officers covered by this Code are expected to uphold the standards set forth below in addition to other policies and procedures adopted by ERIE to: • Promote honest and ethical conduct, including the ethical handling of conflicts of interest. • Promote full, fair, accurate, timely, and understandable disclosure. • Promote compliance with applicable laws and governmental rules and regulations. • Deter wrongdoing. Honest and Ethical Conduct Each Financial Officer has a duty to ERIE to act with integrity in both words and in action. Integrity requires, among other things, being honest and candid. Financial Officers are expected to: • Act with integrity, including being honest and candid while still maintaining the confidentiality of information where required or consistent with ERIE’s policies. • Observe both the form and spirit of laws and governmental rules and regulations, accounting standards and ERIE policies. • Adhere to a high standard of business ethics. Compliance with Laws and Regulations Financial Officers are responsible to be familiar and comply with all applicable federal and state laws, rules and regulations.

3 Conflict of Interest A Conflict of Interest (COI) exists when a Financial Officer’s personal or non-ERIE business-related activities influence work and work-related decisions or result in that Financial Officer or a third party obtaining an improper gain or advantage. Financial Officers are expected to: • Act ethically, with honesty and integrity. • Avoid actual or apparent conflicts of interest between personal and professional relationships. • Discuss any material transaction or relationship that could reasonably be expected to give rise to a conflict of interest with the ERIE’s General Counsel and the CFO. • Complete an annual COI form. • Complete a revised form at any point in the year if circumstances change and a yes response is now appropriate. A COI may arise: • When a Financial Officer takes actions or has interests that may make it difficult to perform their work objectively and effectively for ERIE. • From an activity where a Financial Officer’s family, household members, or close/personal friends are involved, to the extent that it may influence the Financial Officer’s work-related decisions. • When a Financial Officer’s personal interest interferes or appears to interfere with the interests of ERIE. • From any significant ownership interest in any supplier or customer. • From any consulting or employment relationship with any customer, supplier, or competitor. If a financial-related conflict of interest or the appearance of a conflict of interest becomes known, it must be disclosed to Corporate Compliance by way of a conflict of interest form submission. Corporate Compliance will review the form to evaluate the potential conflict of interest and determine if any action is required. Financial Officers are expected to guard against the appearance of a conflict when giving or receiving gifts. See the Gifts & Entertainment Policy and Policy with Respect to Related Person Transactions for more information.
