Recent Accounting Pronouncements	Recent Accounting Pronouncements ASU 2014-01- Investments—Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Qualified Affordable Housing Projects (a consensus of the FASB Emerging Issues Task Force): In January 2014, the Financial Accounting Standards Board (the "FASB") issued Accounting Standards Update 2014-01, Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Qualified Affordable Housing Projects (a consensus of the FASB Emerging Issues Task Force). The ASU permits reporting entities to make an accounting policy election to account for their investments in qualified affordable housing projects using the proportional amortization method if certain conditions are met. Under the proportional amortization method, an entity amortizes the initial cost of the investment in proportion to the tax credits and other tax benefits received and recognizes the net investment performance in the income statement as a component of income tax expense. Additionally, a reporting entity should disclose information that enables users of its financial statement to understand the nature of its investments in qualified affordable housing projects, and the effect of the measurement of its investments in qualified affordable housing projects and the related tax credits on its financial position and results of operations. The new guidance became effective for annual periods, and interim reporting periods within those annual periods, beginning after December 15, 2014. Park adopted this guidance in the first quarter of 2015. The guidance was applied retrospectively to all prior periods presented. The adoption resulted in adjustments to reduce beginning retained earnings, other assets and the prior period consolidated condensed statements of income. See Note 16 - Investment in Qualified Affordable Housing for further details. ASU 2014-04 - Receivables—Troubled Debt Restructurings by Creditors (Subtopic 310-40): Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure (a consensus of the FASB Emerging Issues Task Force): In January 2014, FASB issued Accounting Standards Update 2014-04, Receivables—Troubled Debt Restructurings by Creditors (Subtopic 310-40): Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure (a consensus of the FASB Emerging Issues Task Force). The ASU clarifies when an in substance repossession or foreclosure occurs and a creditor is considered to have received physical possession of real estate property collateralizing a consumer mortgage loan. Specifically, the new ASU requires a creditor to reclassify a collateralized consumer mortgage loan to real estate property upon obtaining legal title to the real estate collateral, or the borrower voluntarily conveying all interest in the real estate property to the lender to satisfy the loan through a deed in lieu of foreclosure or similar legal agreement. Additional disclosures are required detailing the amount of foreclosed residential real estate property held by the creditor and the recorded investment in consumer mortgages collateralized by real estate property that are in the process of foreclosure. The new guidance is effective for annual periods, and interim reporting periods within those annual periods, beginning after December 15, 2014. The adoption of this guidance as of January 1, 2015 did not have a material impact on Park's consolidated financial statements, but resulted in additional disclosures. See Note 5 - Other Real Estate Owned. ASU 2014-09 - Revenue from Contracts with Customers (Topic 606): In May 2014, the FASB issued Accounting Standards Update 2014-09, Revenue from Contracts with Customers (Topic 606). The ASU creates a new topic, Topic 606, to provide guidance on revenue recognition for entities that enter into contracts with customers to transfer goods or services or enter into contracts for the transfer of nonfinancial assets. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Additional disclosures are required to provide quantitative and qualitative information regarding the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. The new guidance is effective for annual reporting periods, and interim reporting periods within those annual periods, beginning after December 15, 2017. Management is currently evaluating the impact of the adoption of this guidance on Park's consolidated financial statements. ASU 2014-11 - Transfers and Servicing (Topic 860): Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures: In June 2014, the FASB issued Accounting Standards Update 2014-11, Transfers and Servicing (Topic 860): Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures. The amendments in this ASU change the accounting for repurchase-to-maturity transactions and linked repurchase financings to secured borrowing accounting, which is consistent with the accounting for other repurchase agreements. The amendments also require two new disclosures. The first disclosure requires an entity to disclose information on transfers accounted for as sales in transactions that are economically similar to repurchase agreements. The second disclosure provides increased transparency about the types of collateral pledged in repurchase agreements and similar transactions accounted for as secured borrowings. The accounting changes are effective for annual periods, and interim reporting periods within those annual periods, beginning after December 15, 2014. The disclosure for certain transactions accounted for as a sale is required to be presented for interim and annual periods beginning after December 15, 2014, with all other disclosure requirements required to be presented for annual periods beginning after December 15, 2014, and for interim periods beginning after March 15, 2015. The adoption of this guidance as of January 1, 2015 did not have an impact on Park's consolidated financial statements, but resulted in additional disclosures. See Note 17 - Repurchase Agreement Borrowings. ASU 2015-02 - Consolidation (Topic 810): Amendments to the Consolidation Analysis: In February 2015, the FASB issued Accounting Standards Update 2015-02, Consolidation (Topic 810): Amendments to the Consolidation Analysis. The ASU amends the current consolidation guidance and affects both the variable interest entity and voting interest entity consolidation models. The new guidance is effective for annual reporting periods and interim reporting periods within those annual periods, beginning after December 15, 2015. Early adoption is permitted. Management is currently evaluating the impact of the adoption of this guidance on Park’s consolidated financial statements.
