Accounting Standards Update and Change in Accounting Principle [Abstract]
Recent Accounting Pronouncements	Adoption of New Accounting Pronouncements and Issued But Not Yet Effective Accounting Standards The following is a summary of new accounting pronouncements impacting Park's consolidated condensed financial statements: Adoption of New Accounting Pronouncements ASU 2025-08 - Financial Instruments - Credit Losses (Topic 326) - Purchased Loans: In November 2025, FASB issued ASU 2025-08 - Financial Instruments - Credit Losses (Topic 326) - Purchased Loans. ASU 2025-08 expands the use of the gross-up method to certain acquired loans beyond purchased financial assets with credit deterioration ("PCD" assets). Under the gross-up method, an allowance for credit losses is recognized at the acquisition date with an offset to the asset's amortized cost basis. ASU 2025-08 does the following: (1) applies the gross-up method to acquired non-PCD assets that are purchased seasoned loans and provides criteria for determining whether acquired loans qualify as purchased seasoned loans; (2) for purchased seasoned loans, eliminates the Day 1 credit loss expense and reduces interest income recognized in subsequent periods as the gross-up method will now apply to these loans; (3) maintains the guidance for PCD assets; (4) results in narrow subsequent measurement differences between purchased seasoned loans and PCD assets. ASU 2025-08 is effective for interim and annual reporting periods in fiscal years beginning after December 15, 2026 and is applied on a prospective basis. Early adoption is permitted in an interim or annual reporting period in which financial statements have not yet been issued or made available for issuance. Park elected to adopt ASU 2025-08 effective January 1, 2025. The adoption of ASU 2025-08 did not have an impact on Park's existing loan portfolio or allowance for credit losses, but did impact the accounting for First Citizens purchased loans. Issued But Not Yet Effective Accounting Standards ASU 2023-06 - Disclosure Improvements - Codification Amendments in Response to the SEC's Disclosure Update and Simplification Initiative: In October 2023, FASB issued ASU 2023-06 - Disclosure Improvements - Codification Amendments in Response to the SEC's Disclosure Update and Simplification Initiative. ASU 2023-06 amends the disclosure or presentation requirements related to various subtopics in the FASB Accounting Standards Codification. ASU 2023-06 was issued in response to the SEC's August 2018 final rule that updated and simplified disclosure requirements. In the final rule, the SEC identified 27 disclosure requirements that were incremental to those in the ASC and referred them to the FASB for potential incorporation into US GAAP. To avoid duplication, the SEC intended to eliminate those disclosure requirements from existing SEC regulations if the FASB incorporated them into the relevant ASC subtopics. The disclosure requirements are currently included in either SEC Regulation S-X or SEC Regulation S-K. ASU 2023-06 adds 14 of the 27 identified disclosure or presentation requirements to the ASC. For entities, like Park, that are subject to the SEC's existing disclosure requirements, the effective date for each amendment will be the date on which the SEC's removal of that related disclosure from Regulation S-X or Regulation S-K becomes effective, with early adoption prohibited. The amendments are to be applied prospectively and if by June 30, 2027, the SEC has not removed the applicable requirement from Regulation S-X or S-K, the pending content of the related amendment will be removed from the ASC and will not become effective for any entity. Management intends to adopt the provisions of ASU 2023-06 on their respective effective dates. The adoption of the provisions of ASU 2023-06 is not expected to have a material impact on Park's consolidated financial statements.
