EBP, Nonparticipant-Directed Investment Non-participant Directed Investments
The following information represents the assets and the significant components of changes in assets related to the Plan’s investment in Park National Corporation Common Stock, an undetermined portion of which is non-participant directed based upon Plan provisions. Prior to the transition of the Plan trustee and administrative service provider from Park to Fidelity Management Trust Company as Plan trustee and Fidelity Workplace Services LLC as the Plan recordkeeper ("Fidelity") in June 2024, initial contributions were deposited into the Plan in the form of cash with shares of Park National Corporation Common Stock purchased on a delayed basis. After the trustee and administrative service provider transition, shares of Park National Corporation Common Stock are purchased utilizing a stock purchase account. The stock purchase account is used to facilitate the money movements associated with the share accounted stock. As the market place only recognizes whole share trades and Fidelity record keeps fractional shares, the stock purchase account houses the resulting differences that are caused by normal trading activity. The stock purchase account balances are invested in a Fidelity Investments money market account.
