Accounting Policies [Abstract]
New Accounting Pronouncements	New Accounting Pronouncements: From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board ("FASB") or other standard setting bodies that are adopted by Peoples as of the required effective dates. Unless otherwise discussed, management believes the impact of any recently issued standards, including those issued but not yet effective, will not have a material impact on Peoples' financial statements taken as a whole. In August 2016, the FASB issued Accounting Standards Update ("ASU") 2016-15 - Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. The update addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice. This new accounting guidance will be effective for interim and annual reporting periods beginning after December 15, 2019 (effective January 1, 2020, for Peoples). The adoption of the new accounting guidance is not expected to have a material effect on Peoples' statement of cash flow. In June 2016, the FASB issued ASU 2016-13 - Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The revised accounting guidance will remove all recognition thresholds and will require a company to recognize an allowance for credit losses for the difference between the amortized cost basis of a financial instrument and the amount of amortized cost that the company expects to collect over the instrument's contractual life. It also amends the credit loss measurement guidance for available-for-sale debt securities and beneficial interests in securitized financial assets. This new accounting guidance will be effective for interim and annual reporting periods beginning after December 15, 2019 (effective January 1, 2020, for Peoples). Peoples is currently evaluating the impact of adopting the new accounting guidance on Peoples' consolidated financial statements. In May 2016, the FASB issued ASU 2016-12 - Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients. This accounting guidance can be implemented using either a retrospective method or a cumulative-effect approach. This accounting guidance provides clarification of the collectibility criterion and when revenue would be recognized for certain contracts. This new accounting guidance will be effective for interim and annual reporting periods beginning after December 15, 2018 (effective January 1, 2019, for Peoples). Management's preliminary analysis suggests that the adoption of the new accounting guidance is not expected to have a material effect on Peoples' financial condition or results of operations. There are many aspects of the new accounting guidance that are still being interpreted, and the FASB has recently issued and proposed updates to certain aspects of the guidance. Therefore, the results of Peoples' preliminary analysis of the materiality of the adoption of the new accounting guidance may change based on the conclusions reached as to the application of the new accounting guidance. In March 2016, the FASB issued ASU 2016-09 - Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. The objective of the simplification initiative is to identify, evaluate, and improve areas of US GAAP for which cost and complexity can be reduced while maintaining or improving the usefulness of the information provided to users of financial statements. The areas for simplification involve several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. Amendments related to the timing of when excess tax benefits are recognized, minimum statutory withholding requirements, forfeitures, and intrinsic value are to be applied using a modified retrospective transition method by means of a cumulative-effect adjustment to equity as of the beginning of the period in which the accounting guidance is adopted. For public entities, the amendments are effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods. Peoples will adopt this new accounting guidance as required, and it is not expected to have a material impact on Peoples' results of operations. In March 2016, the FASB issued ASU 2016-08 - Revenue from Contracts with Customers (Topic 606) which amended the accounting guidance issued by the FASB in May 2014 that revised the criteria for determining when to recognize revenue from contracts with customers and expanded disclosure requirements. The amendment defers the effective date by one year (reflected below). This accounting guidance can be implemented using either a retrospective method or a cumulative-effect approach. This new accounting guidance will be effective for interim and annual reporting periods beginning after December 15, 2018 (effective January 1, 2019, for Peoples). Early adoption is permitted but only for interim and annual reporting periods beginning after December 15, 2016. Peoples has elected to implement the new accounting guidance using a cumulative-effect approach and will adopt this new accounting guidance as required. Management's preliminary analysis suggests that the adoption of the new accounting guidance is not expected to have a material effect on Peoples' financial condition or results of operations. There are many aspects of the new accounting guidance that are still being interpreted, and the FASB has recently issued and proposed updates to certain aspects of the accounting guidance. Therefore, the results of Peoples' preliminary analysis of the materiality of the adoption of the new accounting guidance may change based on the conclusions reached as to the application of the new accounting guidance. In March 2016, the FASB issued ASU 2016-06 - Derivatives and Hedging (Topic 815): Contingent Put and Call Options in Debt Instruments. The amendment is intended to resolve the diversity in practice by assessing whether contingent call (put) options that can accelerate the payment of principal on debt instruments are clearly and closely related to the debt instrument hosts, which is one of the criteria for bifurcating an embedded derivative. When a call (put) option is contingently exercisable, an entity does not have to assess whether the event that triggers the ability to exercise the call (put) option is related to interest rates or credit risks. For public entities, the amendments are effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods. Peoples is currently evaluating the impact of adopting the new accounting guidance on Peoples' consolidated financial statements, but it is not expected to have a material impact. In February 2016, the FASB issued ASU 2016-02 - Leases (Topic 842). The amendment was issued to improve the financial reporting of leasing activities and provide a faithful representation of leasing transactions and improve understanding and comparability of a lessee's financial statements. Under the new accounting guidance, a lessee will be required to recognize assets and liabilities for leases with lease terms of more than 12 months. The ASU will require both finance and operating leases to be recognized on the balance sheet. The ASU will affect all companies and organizations that lease real estate. The ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018 (effective January 1, 2019, for Peoples). Peoples will adopt this new accounting guidance as required, but it is not expected to have a material impact on Peoples' consolidated financial statements. In January 2016, the FASB issued ASU 2016-01 - Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. The amendment is intended to enhance the reporting model for financial instruments to provide users of financial statements with more useful information. The new ASU requires equity investments to be measured at fair value with changes in fair value recognized in net income. However, a reporting organization may choose to measure equity investments that do not have readily determinable fair values at cost minus impairment (if any), from observable price changes in orderly transactions for similar investments of the same issuer. The ASU is effective for fiscal years beginning after December 15, 2019 (effective January 1, 2020, for Peoples). Peoples is currently evaluating the impact of adopting the new accounting guidance on Peoples' consolidated financial statements which may result in an impact to the income statement on a quarterly and annual basis, as market rates fluctuate. Peoples will adopt this accounting guidance as required.
