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. The following should be read in conjunction with "Note 1 Summary of Significant Accounting Policies" of the Notes to the Consolidated Financial Statements included in Peoples’ 2019 Form 10-K. 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.

Accounting Standards Update ("ASU") 2020-04 - Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. This guidance provides optional expedients and exceptions for applying US GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. This update is effective as of March 12, 2020 through December 31, 2022. Per the guidance, Peoples is continuing to evaluate the impact of ASU 2020-04 on Peoples' consolidated financial statements.

ASU 2016-13 - Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. This accounting guidance replaces the "incurred loss" model for recognizing credit losses with an "expected loss" model, referred to as the Current Expected Credit Loss ("CECL") model. Under the CECL model, Peoples is required to present certain financial assets carried at amortized cost, such as loans held-for-investment and held-to-maturity investment securities, at the net amount expected to be collected. ASU 2018-19 clarified that receivables arising from operating leases are not within the scope of Accounting Standards Codification ("ASC") 326-20, and should be accounted for according to ASC 842.

The measurement of expected credit losses is to be based on information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. The measurement is to take place at the time the financial asset is first added to the balance sheet and periodically thereafter. This differs significantly from the "incurred loss" model under previous US GAAP accounting guidance, which delayed recognition until it was probable a loss had been incurred.

Peoples adopted ASU 2016-13 using the modified retrospective method for all financial assets measured at amortized cost on January 1, 2020. Reporting periods beginning after December 31, 2019 are presented as required by ASU 2016-13, while prior period amounts continue to be reported in accordance with previously applicable US GAAP requirements. Peoples is using the prospective transition approach for financial assets purchased with credit deterioration that were previously classified as purchased credit impaired assets and accounted for under ASC 310-30.

As of January 1, 2020, Peoples recorded a one-time cumulative-effect adjustment to reduce retained earnings by $3.7 million, net of statutory corporate federal income taxes, an increase in allowance for credit losses of $5.8 million and an increase in unfunded

commitment liability of $1.5 million. On January 1, 2020, the amortized cost basis of the purchased credit deteriorated assets was adjusted to reflect the addition of $2.6 million to establish the allowance for credit losses. The remaining interest-related discount is being accreted into interest income at the effective interest rate beginning on January 1, 2020. As of January 1, 2020, Peoples did not record an allowance for credit losses for available-for-sale investment securities, as all unrealized losses on these securities were deemed to be non-credit in nature, with no credit deterioration upon review by Peoples. Peoples recorded an allowance for credit losses for held-to-maturity securities of $7,000 as of January 1, 2020.

Investment Securities: Investment securities are recorded initially at cost, which includes premiums and discounts if purchased at other than par or face value. Peoples amortizes premiums and accretes discounts as an adjustment to interest income on a level yield basis. The cost of investment securities sold, excluding equity investment securities, and any resulting gain or loss, is based on the specific identification method and recognized as of the trade date. The cost of equity investment securities is based on the weighted-average method.

Peoples determines the appropriate classification of investment securities at the time of purchase. Held-to-maturity securities are those securities that Peoples has the positive intent and ability to hold to maturity and are recorded at amortized cost. Available-for-sale securities are those securities that would be available to be sold in the future in response to Peoples' liquidity needs, changes in market interest rates, and asset-liability management strategies, among other considerations. Available-for-sale securities are reported at fair value, with unrealized gains and losses reported in total stockholders' equity as a separate component of accumulated other comprehensive income or loss, net of applicable deferred income taxes.

Certain restricted equity investment securities that do not have readily determinable fair values and for which Peoples does not exercise significant influence, are carried at cost. These cost method securities are reported in other investment securities on the Unaudited Consolidated Balance Sheets and consist primarily of shares of the Federal Home Loan Bank of Cincinnati (the "FHLB") and the Federal Reserve Bank of Cleveland (the "FRB").

Peoples evaluates available-for-sale investment securities on a quarterly basis to determine how much, if any, allowance for credit losses is required. Peoples reviews available-for-sale investment securities at an unrealized loss position, with potential exposure to a credit event (which excludes U.S. government and U.S. government sponsored agency securities) to determine if the unrealized loss was credit-related. An allowance for credit losses is recorded to the extent that the unrealized losses are credit-related and likely to be permanent.

Peoples evaluates held-to-maturity investment securities on a quarterly basis in determining an allowance for credit losses. Peoples has determined that the loss given default for U.S. government sponsored enterprise investment securities is zero, due to the fact that it is unlikely the ultimate guarantor (the U.S. government) would not perform on its implicit guarantee in the event of default. The remaining securities are included in the calculation of the allowance for credit losses for held-to-maturity investment securities.
