Summary of significant accounting policies
Summary of significant accounting policies	1. Summary of significan t accounting policies: Nature of operations Peoples Financial Services Corp., a bank holding company incorporated under the laws of Pennsylvania, provides a full range of financial services through its wholly-owned subsidiary, Peoples Security Bank and Trust Company (“the Bank”), collectively, the “Company” or “Peoples”. The Company services its retail and commercial customers through Basis of presentation The accompanying unaudited consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10-01 of Regulation S-X. In the opinion of management, all normal recurring adjustments necessary for a fair presentation of the consolidated financial position and results of operations for the periods presented have been included. All significant intercompany balances and transactions have been eliminated in consolidation. Prior period amounts are reclassified when necessary to conform to the current year’s presentation. These reclassifications did not have any effect on the consolidated operating results or financial position of the Company. The consolidated operating results and financial position of the Company for the three and six months ended and as of June 30, 2023, are not necessarily indicative of the results of consolidated operations and financial position that may be expected in the future. The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Significant estimates that are particularly susceptible to material change in the near term relate to the determination of the allowance for credit losses, fair value of financial instruments, the valuation of deferred tax assets, and impairment of goodwill. Actual results could differ from those estimates. For additional information and disclosures required under GAAP, reference is made to the Company’s Annual Report on Form 10-K for the period ended December 31, 2022. Immaterial Prior Period Adjustment During the quarter-ended June 30, 2023, the Company became aware that the unaudited consolidated financial statements for the three months ended March 31, 2023 contained an immaterial misstatement. The Company determined that the allowance for credit losses was overstated by $1.5 million as of March 31, 2023. The adjustment consisted of $1.1 million related to the adoption of Accounting Standards Update ( ASU) 2016-13, “ Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments ” that the Company adopted effective January 1, 2023 and a $0.4 million reduction in the first quarter 2023 provision for credit loss requirement. This immaterial misstatement was identified during the second quarter review of the Company’s loan segment loss rates and an adjustment was made to the municipal loan segment to better align its loss rates with the risk inherent in this loan product. The Company evaluated this prior period adjustment in accordance with SEC Staff Accounting Bulletin (SAB) 99, Materiality (ASC 250-10-S99) and based on its quantitative and qualitative analysis determined that this prior period adjustment was not material to the consolidated financial statements of any of the impacted unaudited 2023 periods. Therefore, an amendment to the previously filed quarterly report on Form 10-Q as of March 31, 2023 was not required . Consequently, the Company elected to correct this prior period adjustment in the current period. The $1.5 million credit to the provision for credit losses and reduction in the allowance for credit losses is reflected in the unaudited consolidated financial statements for the three and six months ended June 30, 2023. Third Quarter Dividend Decl aration On July 28, 2023, the Board of Directors declared a third quarter dividend of $0.41 per share. The dividend is payable on September 15, 2023 to shareholders of record as of August 31, 2023. Adoption of New Accounting Standard On January 1, 2023, the Company adopted ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments”, which replaced the incurred loss methodology with an expected loss methodology that is referred to as the current expected credit loss (CECL) model. The Company adopted ASU 2016-13 using a modified retrospective approach. Results for reporting periods beginning after January 1, 2023 are presented under Topic 326, while prior period amounts continue to be reported in accordance with previously applicable GAAP. At adoption, the Company decreased its allowance for credit losses by $3.0 million. Upon adoption the Company recorded a cumulative effect adjustment that increased stockholders’ equity by $2.4 million, net of tax. The Company adopted ASU 2022-02, “Financial Instruments - Credit Losses (Topic 326) Troubled Debt Restructurings and Vintage Disclosures” effective January 1, 2023. The ASU addresses and amends areas identified by the FASB as part of its post-implementation review of the accounting standard that introduced the current expected credit losses model. The amendments eliminate the accounting guidance for troubled debt restructurings by creditors that have adopted the current expected credit losses model and enhance the disclosure requirements for loan refinancings and restructurings made with borrowers experiencing financial difficulty. In addition, the amendments require disclosure of current-period gross write-offs for financing receivables and net investment in leases by year of origination in the vintage disclosures. Allowance for Credit Losses The allowance for credit losses represents the estimated amount considered necessary to cover lifetime expected credit losses inherent in financial assets at the balance sheet date. The measurement of expected credit losses is applicable to loans receivable and securities measured at amortized cost. It also applies to off-balance sheet credit exposures such as loan commitments and unused lines of credit. The allowance is established through a provision for credit losses that is charged against income. The methodology for determining the allowance for credit losses is considered a critical accounting policy by management because of the high degree of judgment involved, the subjectivity of the assumptions used, and the potential for changes in the forecasted economic environment that could result in changes to the amount of the recorded allowance for credit losses. The allowance for credit losses is reported separately as a contra-asset on the consolidated balance sheets. The expected credit loss for unfunded lending commitments and unfunded loan commitments is reported on the consolidated balance sheets in other liabilities while the provision for credit losses related to unfunded commitments is reported in other non-interest expense in the consolidated statements of income and comprehensive income (loss). Allowance for Credit Losses on Loans Receivable The allowance for credit losses on loans is deducted from the amortized cost basis of the loan to present the net amount expected to be collected. Expected losses are evaluated and calculated on a collective, or pooled, basis for those loans which share similar risk characteristics. The Company has chosen to segment its portfolio consistent with the manner in which it manages credit risk. Such segments include residential real estate, consumer, commercial and industrial, commercial real estate and municipal. At each reporting period, the Company evaluates whether loans within a pool continue to exhibit similar risk characteristics. If the risk characteristics of a loan change, such that they are no longer similar to other loans in the pool, the Company will evaluate the loan with a different pool of loans that share similar risk characteristics. If the loan does not share risk characteristics with other loans, the Company will evaluate the loan on an individual basis. The Company evaluates the pooling methodology at least annually. Loans are charged off against the allowance for credit losses when the Company believes the balances to be uncollectible. Expected recoveries do not exceed the aggregate of amounts previously charged off or expected to be charged off. The Company estimates the allowance for credit losses on loans using an advanced probability of default model which incorporates probability of default, loss given default, exposure at default and probability of attrition attributes. The model considers relevant available information at both the portfolio and loan level from internal data that is supplemented by shared data pool information. The model also incorporates reasonable and supportable economic forecasts. After the reasonable and supportable forecast period, the model reverts to average historical losses. Expected credit losses are estimated over the contractual term of the loans, adjusted for expected prepayments when appropriate. The contractual term excludes expected extensions, renewals, and modifications. Also included in the allowance for credit losses on loans are qualitative reserves to cover losses that are expected but, in the Company’s assessment, may not be adequately represented in the quantitative analysis described above. Factors that the Company considers include changes in lending policies and procedures, changes in management, changes in the quality of the loan review process, the existence of any concentrations of credit and other external factors. Individually Evaluated Loans On a case-by-case basis, the Company may conclude that a loan should be evaluated on an individual basis based on its disparate risk characteristics. The Bank has determined that any loans currently on nonaccrual status or are 90 or more days past due and still accruing are considered impaired and should be individually evaluated for losses. When the Company determines that a loan no longer shares similar risk characteristics with other loans in the portfolio, the allowance will be determined on an individual basis using the present value of expected cash flows or, for collateral-dependent loans, the fair value of the collateral as of the reporting date, less estimated selling costs, as applicable. If the fair value of the collateral is less than the amortized cost basis of the loan, the Company will establish a reserve for the difference between the fair value of the collateral, less costs to sell and carrying costs at the reporting date and the amortized cost basis of the loan. If this amount is deemed uncollectible, the Company will charge-off that amount. Acquired Loans Acquired loans are included in the Company's calculation of the allowance for credit losses. How the allowance on an acquired loan is recorded depends on whether or not it has been classified as a Purchased Credit Deteriorated (“PCD”) loan. PCD loans are loans acquired at a discount that is due, in part, to credit quality. PCD loans are accounted for in accordance with ASC Subtopic 326-20 and are initially recorded at fair value as determined by the sum of the present value of expected future cash flows and an allowance for credit losses at acquisition. The allowance for PCD loans is recorded through a gross-up effect, while the allowance for acquired non-PCD loans is recorded through provision expense, consistent with originated loans. Thus, the determination of which loans are PCD and non-PCD can have a significant impact on the accounting for these loans. Subsequent to acquisition, the allowance for PCD loans will generally follow the same estimation, provision and charge-off process as non-PCD acquired and originated loans. Under FASB ASC Topic 326, a PCD asset is defined as an individual financial asset that as of the date of acquisition has experienced a more than insignificant deterioration in credit quality since origination as determined during the acquisition process. Upon identification of these assets, the amortized cost basis will be adjusted at the time of acquisition to reflect any impairment amount. After acquisition, PCD loans will be either collectively evaluated for reserve requirements or individually evaluated if on nonaccrual status or are 90 or more days past due and still accruing. Allowance for Credit Losses on Off-Balance Sheet Commitments The Company is required to include unfunded commitments that are expected to be funded in the future within the allowance calculation, other than those that are unconditionally cancelable. To arrive at that reserve, the reserve percentage for each applicable segment is applied to the unused portion of the expected commitment balance and is multiplied by the expected funding rate. To determine the expected funding rate, the Company uses a historical utilization rate for each segment. As noted above, the allowance for credit losses on unfunded loan commitments is included in other liabilities on the consolidated balance sheets and the related credit expense is recorded in other non-interest expense in the consolidated statements of income and comprehensive income (loss). Allowance for Credit Losses on Held to Maturity Securities The Company’s portfolio of held to maturity securities consists of municipal bonds and U.S. agency residential mortgage-backed securities which are highly rated by major rating agencies and have a long history of no credit losses. In estimating the net amount expected to be collected for held to maturity securities in an unrealized loss position, a historical loss based method is utilized. Allowance for Credit Losses on Available for Sale Securities For available for sale securities in an unrealized loss position, the Company first assesses whether it intends to sell, or it is more likely than not that it will be required to sell the security before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the security’s amortized cost basis is written down to fair value through income. For securities available for sale that do not meet the above criteria, the Company evaluates whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, the Company considers the extent to which fair value is less than amortized cost, any changes to the rating by a rating agency, and adverse conditions related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. If the present value of the cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for credit losses is recorded for the credit loss, limited by the amount that the fair value is less than the amortized cost. Any impairment that has not been recorded through an allowance for credit losses is recognized in other comprehensive income, net of tax. The Company elected the practical expedient of zero loss estimates for securities issued by U.S. government entities and agencies. These securities are either explicitly or implicitly guaranteed by the U.S. government, are highly rated by major agencies and have a long history of no credit losses. Accrued Interest Receivable The Company made an accounting policy election to exclude accrued interest receivable from the amortized cost basis of loans, available for sale securities, and held to maturity securities. Accrued interest receivable on loans is reported as a component of accrued interest receivable on the Consolidated Balance Sheets, totaled $9.7 million at June 30, 2023 and is excluded from the estimate of credit losses. Accrued interest receivable on available for sale securities and held to maturity securities, also a component of accrued interest receivable on the Consolidated Balance Sheets, and totaled $1.5 million and $198 thousand, respectively, at June 30, 2023 and is excluded from the estimate of credit losses. Recent accounting standards 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 the Company 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 the Company’s annual report on Form 10-K for the year ended December 31, 2022. 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 the Company’s consolidated financial statements. ASU 2023-01, “Leases (Topic 842) - Common Control Arrangements” (ASU 2023-01) requires entities to determine whether a related party arrangement between entities under common control is a lease. If the arrangement is determined to be a lease, an entity must classify and account for the lease on the same basis as an arrangement with an unrelated party (on the basis of legally enforceable terms and conditions). ASU 2023-01 is effective January 1, 2024 and is not expected to have an impact on our financial statements. ASU 2023-02 “Investments - Equity Method and Joint Ventures (Topic 323) - Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method” (ASU 2023-02) permits reporting entities to elect to account for their tax equity investments, regardless of the tax credit program from which the income tax credits are received, using the proportional amortization method if certain conditions are met. ASU 2023-02 is effective January 1, 2024 and is not expected to have an impact on our financial statements.

The Company estimated no allowance for credit losses for its investment securities classified as held to maturity at January 1, 2023 or June 30, 2023, as the portfolio of held to maturity securities consists entirely of U.S. government sponsored enterprises, agencies and states and political subdivisions investments. The unrealized losses on securities are primarily due to the changes in market interest rates subsequent to purchase. In addition, the Company does not intend to sell and does not believe that it is more likely than not that it will be required to sell these investments until there is a full recovery of the unrealized loss, which may be at maturity. As a result, there was no allowance for credit loss required on available for sale debt securities in an unrealized loss position at June 30, 2023 and December 31, 2022.

Loans are individually analyzed for credit risk by classifying them within the Company’s internal risk rating system. The Company’s risk rating classifications are defined as follows: ● Pass- A loan to borrowers with acceptable credit quality and risk that is not adversely classified as Substandard, Doubtful, Loss nor designated as Special Mention. ● Special Mention- A loan that has potential weaknesses that deserves management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or in the institution’s credit position at some future date. Special Mention loans are not adversely classified since they do not expose the Company to sufficient risk to warrant adverse classification. ● Substandard- A loan that is inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified must have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the bank will sustain some loss if the deficiencies are not corrected. ● Doubtful – A loan classified as Doubtful has all the weaknesses inherent in one classified Substandard with the added characteristic that the weaknesses make the collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. ● Loss- A loan classified as Loss is considered uncollectible and of such little value that its continuance as bankable loan is not warranted. This classification does not mean that the loan has absolutely no recovery or salvage value, but rather it is not practical or desirable to defer writing off this basically worthless asset even though partial recovery may be affected in the future.

The amendments in ASU 2022-02 eliminated the recognition and measure of troubled debt restructurings and enhanced disclosures for loan modifications to borrowers experiencing financial difficulty. There were no loans made to borrowers experiencing financial difficulty that were modified during the six months ended June 30, 2023 and hence there were no loans made to borrowers experiencing financial difficulty that subsequently defaulted. Information on loan modifications prior to the adoption of ASU 2022-02 on January 1, 2023 is presented in accordance with the applicable accounting standards in effect at that time. During the three and six months ended June 30, 2022, the Company did not modify any loans that were determined to be a troubled debt restructuring.

Fair value estimates
Fair value of estimates	7. Fair value estimates: The Company uses fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosure under GAAP. Fair value estimates are calculated without attempting to estimate the value of anticipated future business and the value of certain assets and liabilities that are not considered financial. Accordingly, such assets and liabilities are excluded from disclosure requirements. In accordance with FASB ASC 820, “Fair Value Measurements and Disclosures,” fair value is the price that would be received to sell an asset or transfer a liability in an orderly transaction between market participants at the measurement date. Fair value is best determined based upon quoted market prices. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. In that regard, the derived fair value estimates cannot be substantiated by comparison to independent markets. In many cases, these values cannot be realized in immediate settlement of the instrument. Current fair value guidance provides a consistent definition of fair value, which focuses on exit price in an orderly transaction that is not a forced liquidation or distressed sale between participants at the measurement date under current market conditions. If there has been a significant decrease in the volume and level of activity for the asset or liability, a change in valuation technique or the use of multiple valuation techniques may be appropriate. In such instances, determining the price at which willing market participants would transact at the measurement date under current market conditions depends on the facts and circumstances and requires the use of significant judgment. The fair value is a reasonable point within the range that is most representative of fair value under current market conditions. In accordance with GAAP, the Company groups its assets and liabilities generally measured at fair value into three levels based on market information or other fair value estimates in which the assets and liabilities are traded or valued and the reliability of the assumptions used to determine fair value. These levels include: ● Level 1: Unadjusted quoted prices of identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date. ● Level 2: Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. ● Level 3: Significant unobservable inputs that reflect a reporting entity’s own assumptions about the assumptions that market participants would use in pricing an asset or liability. An asset’s or liability’s placement in the fair value hierarchy is based on the lowest level of input that is significant to the fair value estimate. During the periods ended June 30, 2023 and December 31, 2022 there were no transfers in or out of Level 3 . The following methods and assumptions were used by the Company to calculate fair values and related carrying amounts of financial instruments: Investment securities: Interest rate swaps and options: Assets and liabilities measured at fair value on a recurring basis at June 30, 2023 and December 31, 2022 are summarized as follows: Fair Value Measurement Using Quoted Prices in Significant Significant Active Markets for Other Observable Unobservable (Dollars in thousands) Identical Assets Inputs Inputs June 30, 2023 Amount (Level 1) (Level 2) (Level 3) U.S. Treasury securities $ 179,104 $ 179,104 $ $ U.S. government-sponsored enterprises 2,201 2,201 State and municipals: Taxable 56,362 56,362 Tax-exempt 66,864 66,864 Mortgage-backed securities: U.S. government agencies 849 849 U.S. government-sponsored enterprises 86,871 86,871 Corporate debt securities 3,575 3,575 Common equity securities 92 92 Total investment securities $ 395,918 $ 179,196 $ 216,722 $ Interest rate floor-other assets $ 283 $ 283 Interest rate swap-other assets $ 21,523 $ 21,523 Interest rate floor-other liabilities $ (237) $ (237) Interest rate swap-other liabilities $ (20,930) $ (20,930) Fair Value Measurement Using Quoted Prices in Significant Significant Active Markets for Other Observable Unobservable (Dollars in thousands) Identical Assets Inputs Inputs December 31, 2022 Amount (Level 1) (Level 2) (Level 3) U.S. Treasury securities $ 180,297 $ 180,297 $ $ U.S. government-sponsored enterprises 16,370 16,370 State and municipals: Taxable 55,358 55,358 Tax-exempt 88,407 88,407 Mortgage-backed securities: U.S. government agencies 942 942 U.S. government-sponsored enterprises 132,703 132,703 Corporate debt securities 3,626 3,626 Common equity securities 110 110 Total investment securities $ 477,813 $ 180,407 $ 297,406 $ Interest rate floor-other assets $ 1 $ 1 Interest rate swap-other assets $ 21,794 $ 21,794 Interest rate swap-other liabilities $ (21,466) $ (21,466) Assets and liabilities measured at fair value on a nonrecurring basis at June 30, 2023 and December 31, 2022 are summarized as follows: Fair Value Measurement Using Quoted Prices in Significant Significant Active Markets for Other Observable Unobservable (Dollars in thousands) Identical Assets Inputs Inputs June 30, 2023 Amount (Level 1) (Level 2) (Level 3) Loans individually evaluated for credit loss $ 1,926 $ $ $ 1,926 Fair Value Measurement Using Quoted Prices in Significant Other Significant Active Markets for Observable Unobservable (Dollars in thousands) Identical Assets Inputs Inputs December 31, 2022 Amount (Level 1) (Level 2) (Level 3) Impaired loans $ 220 $ $ $ 220 Fair values of impaired loans are based on the present value of expected future cash flows discounted at the loan’s effective interest rate or the fair value of the collateral if the loan is collateral dependent.

In May 2023, the Company’s stockholders approved the 2023 equity incentive plan (“2023 Plan”). Under the 2017 Plan and 2023 Plan the Compensation Committee of the Board of Directors has the authority to, among other things: ● Select the persons to be granted awards under the Plan. ● Determine the type, size and term of awards. ● Determine whether such performance objectives and conditions have been met. ● Accelerate the vesting or exercisability of an award. Persons eligible to receive awards under the 2017 Plan and 2023 Plan include directors, officers, employees, consultants and other service providers of the Company and its subsidiaries. As of June 30, 2023, there were 17,364 shares of the Company’s common stock available for grants as awards pursuant to the 2017 Plan and there were 96,572 shares of the Company’s common stock available for grant as awards pursuant to the 2023 Plan. While the 2017 Plan will remain in effect in accordance with its terms to govern outstanding awards under that plan, the Company intends to make future grants under the 2023 Plan. If any outstanding awards are forfeited by the holder or canceled by the Company, the underlying shares would be available for regrant to others. The 2017 Plan and 2023 Plan authorize grants of stock options, stock appreciation rights, cash awards, performance awards, restricted stock and restricted stock units. For the six months ended June 30, 2023, the Company granted 23,428 awards of restricted stock and restricted stock units under the 2023 Plan. For the six months ended June 30, 2022, the Company granted The non-performance restricted stock grants made in 2023, 2022 and 2021 vest equally over three years . The performance-based restricted stock units vest over three fiscal years and include conditions based on the Company’s three year cumulative diluted earnings per share and three-year average return on equity or tangible equity that determines the number of restricted stock units that may vest. The Company expenses the fair value of all-share based compensation over the requisite service period commencing at grant date. The fair value of restricted stock is expensed on a straight-line basis. Compensation is recognized over the vesting period and adjusted based on the performance criteria. The Company classifies share-based compensation for employees within “salaries and employee benefits expense” on the consolidated statements of income and comprehensive income. The Company recognized net compensation costs of $158 thousand and $316 thousand for the three and six months ended June 30, 2023 for awards granted under the 2017 Plan and did not recognize compensation expense for the awards granted under the 2023 Plan. The Company recognized compensation expense of $191 and $390 thousand for the three and six months ended June 30, 2022 for awards granted under the 2017 Plan. As of June 30, 2023, the Company had $1.7 million of unrecognized compensation expense associated with restricted stock awards. The remaining cost is expected to be recognized over a weighted average vesting period of under 2.0 years.

Derivatives and hedging activities
Derivatives and hedging activities	9. Derivatives and hedging activities Risk Management Objective of Using Derivatives The Company is exposed to certain risk arising from both its business operations and economic conditions. The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company manages economic risks, including interest rate, liquidity, and credit risk primarily by managing the amount, sources, and duration of its assets and liabilities and the use of derivative financial instruments. Specifically, the Company enters into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates. The Company’s existing credit derivatives result from participations of loan participation arrangements, therefore, are not used to manage interest rate risk in the Company’s assets or liabilities. Cash Flow Hedges of Interest Rate Risk The Company’s objectives in using interest rate derivatives are to add stability to interest income/expense and to manage its exposure to interest rate movements. To accomplish this objective, the Company primarily uses interest rate swaps and floors as part of its interest rate risk management strategy. Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. Interest rate floors designated as cash flow hedges involve the receipt of variable-rate amounts from a counterparty if interest rates fall below the strike rate on the contract in exchange for an up-front premium. Such derivatives have been used to hedge the variable cash flows associated with existing variable-rate assets and issuances of debt. For derivatives designated and that qualify as cash flow hedges of interest rate risk, the gain or loss on the derivative is recorded in accumulated other comprehensive income (loss) and subsequently reclassified into interest expense/income in the same period(s) during which the hedged transaction affects earnings. Amounts reported in accumulated other comprehensive income (loss) related to derivatives will be reclassified to interest expense/income as interest payments are made/received on the Company’s variable-rate debt/assets. During the next twelve months, the Company estimates that an additional $22 thousand will be reclassified as a reduction to interest income. Fair Value Hedges of Interest Rate Risk The Company For derivatives designated and that qualify as fair value hedges, the gain or loss on the derivative as well as the offsetting loss or gain on the hedged item attributable to the hedged risk are recognized in interest income. As of June 30, 2023, the following amounts were recorded on the balance sheet related to cumulative basis adjustment for fair value hedges: Line Item in the Statement of Financial Position in Which the Hedged Item is Included Amortized Amount of the Hedged Assets/(Liabilities) Cumulative Amount of Fair Value Hedging Adjustment Included in the Carrying Amount of the Hedged Assets/(Liabilities) (Dollars in thousands) 2023 2022 2023 2022 AFS Securities (1) $ 100,000 $ $ (49) $ Total $ 100,000 $ $ (49) $ (1) These amounts include the amortized cost basis of closed portfolios of fixed rate assets used to designate hedging relationships in which the hedged item is the stated amount of assets in the closed portfolio anticipated to be outstanding for the designated hedged period. At June 30, 2023, the amortized cost basis of the closed portfolios used in these hedging relationships was $145.0 million. The amounts of the designated hedged items were $123.2 million. Non-designated Hedges Derivatives not designated as hedges are not speculative and result from a service the Company provides to certain customers. The Company executes interest rate swaps with commercial banking customers to facilitate their respective risk management strategies. Those interest rate swaps are simultaneously hedged by offsetting derivatives that the Company executes with a third party, such that the Company minimizes its net risk exposure resulting from such transactions. As the interest rate derivatives associated with this program do not meet the strict hedge accounting requirements, changes in the fair value of both the customer derivatives and the offsetting derivatives are recognized directly in earnings. As of June 30, 2023, the Company had The Company’s existing credit derivatives result from participations in or out of interest rate swaps provided by or to external lenders as part of loan participation arrangements, therefore, are not used to manage interest rate risk in the Company’s assets or liabilities.

The Company also has agreements with certain of its derivative counterparties that contain a provision where if the Company fails to maintain its status as a well-capitalized institution, then the counterparty could terminate the derivative positions and the Company would be required to settle its obligations under the agreements. As of June 30, 2023, the termination value of derivatives in a net liability position, which includes accrued interest but excludes any adjustment for nonperformance risk, related to these agreements was $522 thousand. As of December 31, 2022, the termination value of derivatives in a net liability position, which includes accrued interest but excludes any adjustment for nonperformance risk, related to these agreements was counterparties at June 30, 2023. Cash collateral represents the amount that cannot be used to offset our derivative assets and liabilities from a gross basis to a net basis in accordance with the agreement. The cash collateral is exchanged under bilateral collateral and master netting agreements that allow us to offset the net derivative position with the related collateral. The application of the cash collateral cannot reduce the net derivative position below zero. Therefore, excess other collateral, if any, is not reflected above. If the Company had breached any of these provisions it could have been required to settle its obligations under the agreements at the termination value.

Borrowings
Borrowings	11. Borrowings Short-term borrowings consist of FHLB advances representing overnight borrowings or with stated original terms of less than twelve months and other borrowings related to collateral held from derivative counterparties. Total short-term borrowings at June 30, 2023 were $19.5 million as compared to $114.9 million at December 31, 2022. Other borrowings, which include cash collateral pledged by derivative counterparties to offset interest rate exposure, represented the entire balance of $19.5 million at June 30, 2023. The overall decrease to total short-term borrowings from December 31, 2022 is due to paying-off the overnight borrowings at the FHLB with proceeds from the sale of investment securities and deposit growth. The table below outlines short-term borrowings at and for the six months ended June 30, 2023 and at and for the year ended December 31, 2022: At and for the six months ended June 30, 2023 Weighted Weighted Maximum Average Average Ending Average Month-End Rate for Rate at End (Dollars in thousands, except percents) Balance Balance Balance the Year of the Period Other borrowings $ 19,530 $ 15,327 $ 19,530 4.84 % 5.08 % FHLB advances 38,658 158,000 4.86 Total short-term borrowings $ 19,530 $ 53,985 $ 177,530 4.85 % 5.08 % At and for the year ended December 31, 2022 Weighted Weighted Maximum Average Average Ending Average Month-End Rate for Rate at End (Dollars in thousands, except percents) Balance Balance Balance the Year of the Year Other borrowings $ 14,530 $ 10,033 $ 16,100 2.10 % 4.30 % FHLB advances 100,400 32,647 125,975 2.73 4.45 Total short-term borrowings $ 114,930 $ 42,680 $ 142,075 2.58 % 4.43 % The Company has an agreement with the FHLB which allows for borrowings up to its maximum borrowing capacity based on a percentage of qualifying collateral assets. At June 30, 2023, the maximum borrowing capacity was $1.2 billion of which $25.0 million was outstanding in borrowings and $259.7 million was used to issue standby letters of credit to collateralize public fund deposits. At December 31, 2022, the maximum borrowing capacity was $1.2 billion of which $101.0 million was outstanding in borrowings and $388.8 million was used to issue standby letters of credit to collateralize public fund deposits. Advances with the FHLB are secured under terms of a blanket collateral agreement by a pledge of FHLB stock and certain other qualifying collateral, such as investments and mortgage-backed securities and mortgage loans. Interest accrues daily on the FHLB advances based on rates of the FHLB discount notes. The overnight borrowing rate resets each day.

Summary of significant accounting policies
Nature of operations	Nature of operations Peoples Financial Services Corp., a bank holding company incorporated under the laws of Pennsylvania, provides a full range of financial services through its wholly-owned subsidiary, Peoples Security Bank and Trust Company (“the Bank”), collectively, the “Company” or “Peoples”. The Company services its retail and commercial customers through
Basis of presentation	Basis of presentation The accompanying unaudited consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10-01 of Regulation S-X. In the opinion of management, all normal recurring adjustments necessary for a fair presentation of the consolidated financial position and results of operations for the periods presented have been included. All significant intercompany balances and transactions have been eliminated in consolidation. Prior period amounts are reclassified when necessary to conform to the current year’s presentation. These reclassifications did not have any effect on the consolidated operating results or financial position of the Company. The consolidated operating results and financial position of the Company for the three and six months ended and as of June 30, 2023, are not necessarily indicative of the results of consolidated operations and financial position that may be expected in the future. The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Significant estimates that are particularly susceptible to material change in the near term relate to the determination of the allowance for credit losses, fair value of financial instruments, the valuation of deferred tax assets, and impairment of goodwill. Actual results could differ from those estimates. For additional information and disclosures required under GAAP, reference is made to the Company’s Annual Report on Form 10-K for the period ended December 31, 2022.
Immaterial Prior Period Adjustment	Immaterial Prior Period Adjustment During the quarter-ended June 30, 2023, the Company became aware that the unaudited consolidated financial statements for the three months ended March 31, 2023 contained an immaterial misstatement. The Company determined that the allowance for credit losses was overstated by $1.5 million as of March 31, 2023. The adjustment consisted of $1.1 million related to the adoption of Accounting Standards Update ( ASU) 2016-13, “ Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments ” that the Company adopted effective January 1, 2023 and a $0.4 million reduction in the first quarter 2023 provision for credit loss requirement. This immaterial misstatement was identified during the second quarter review of the Company’s loan segment loss rates and an adjustment was made to the municipal loan segment to better align its loss rates with the risk inherent in this loan product. The Company evaluated this prior period adjustment in accordance with SEC Staff Accounting Bulletin (SAB) 99, Materiality (ASC 250-10-S99) and based on its quantitative and qualitative analysis determined that this prior period adjustment was not material to the consolidated financial statements of any of the impacted unaudited 2023 periods. Therefore, an amendment to the previously filed quarterly report on Form 10-Q as of March 31, 2023 was not required . Consequently, the Company elected to correct this prior period adjustment in the current period. The $1.5 million credit to the provision for credit losses and reduction in the allowance for credit losses is reflected in the unaudited consolidated financial statements for the three and six months ended June 30, 2023.
Third Quarter Dividend Declaration	Third Quarter Dividend Decl aration On July 28, 2023, the Board of Directors declared a third quarter dividend of $0.41 per share. The dividend is payable on September 15, 2023 to shareholders of record as of August 31, 2023.
Adoption of New Accounting Standard and Recent accounting standards	Adoption of New Accounting Standard On January 1, 2023, the Company adopted ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments”, which replaced the incurred loss methodology with an expected loss methodology that is referred to as the current expected credit loss (CECL) model. The Company adopted ASU 2016-13 using a modified retrospective approach. Results for reporting periods beginning after January 1, 2023 are presented under Topic 326, while prior period amounts continue to be reported in accordance with previously applicable GAAP. At adoption, the Company decreased its allowance for credit losses by $3.0 million. Upon adoption the Company recorded a cumulative effect adjustment that increased stockholders’ equity by $2.4 million, net of tax. The Company adopted ASU 2022-02, “Financial Instruments - Credit Losses (Topic 326) Troubled Debt Restructurings and Vintage Disclosures” effective January 1, 2023. The ASU addresses and amends areas identified by the FASB as part of its post-implementation review of the accounting standard that introduced the current expected credit losses model. The amendments eliminate the accounting guidance for troubled debt restructurings by creditors that have adopted the current expected credit losses model and enhance the disclosure requirements for loan refinancings and restructurings made with borrowers experiencing financial difficulty. In addition, the amendments require disclosure of current-period gross write-offs for financing receivables and net investment in leases by year of origination in the vintage disclosures. Allowance for Credit Losses The allowance for credit losses represents the estimated amount considered necessary to cover lifetime expected credit losses inherent in financial assets at the balance sheet date. The measurement of expected credit losses is applicable to loans receivable and securities measured at amortized cost. It also applies to off-balance sheet credit exposures such as loan commitments and unused lines of credit. The allowance is established through a provision for credit losses that is charged against income. The methodology for determining the allowance for credit losses is considered a critical accounting policy by management because of the high degree of judgment involved, the subjectivity of the assumptions used, and the potential for changes in the forecasted economic environment that could result in changes to the amount of the recorded allowance for credit losses. The allowance for credit losses is reported separately as a contra-asset on the consolidated balance sheets. The expected credit loss for unfunded lending commitments and unfunded loan commitments is reported on the consolidated balance sheets in other liabilities while the provision for credit losses related to unfunded commitments is reported in other non-interest expense in the consolidated statements of income and comprehensive income (loss). Allowance for Credit Losses on Loans Receivable The allowance for credit losses on loans is deducted from the amortized cost basis of the loan to present the net amount expected to be collected. Expected losses are evaluated and calculated on a collective, or pooled, basis for those loans which share similar risk characteristics. The Company has chosen to segment its portfolio consistent with the manner in which it manages credit risk. Such segments include residential real estate, consumer, commercial and industrial, commercial real estate and municipal. At each reporting period, the Company evaluates whether loans within a pool continue to exhibit similar risk characteristics. If the risk characteristics of a loan change, such that they are no longer similar to other loans in the pool, the Company will evaluate the loan with a different pool of loans that share similar risk characteristics. If the loan does not share risk characteristics with other loans, the Company will evaluate the loan on an individual basis. The Company evaluates the pooling methodology at least annually. Loans are charged off against the allowance for credit losses when the Company believes the balances to be uncollectible. Expected recoveries do not exceed the aggregate of amounts previously charged off or expected to be charged off. The Company estimates the allowance for credit losses on loans using an advanced probability of default model which incorporates probability of default, loss given default, exposure at default and probability of attrition attributes. The model considers relevant available information at both the portfolio and loan level from internal data that is supplemented by shared data pool information. The model also incorporates reasonable and supportable economic forecasts. After the reasonable and supportable forecast period, the model reverts to average historical losses. Expected credit losses are estimated over the contractual term of the loans, adjusted for expected prepayments when appropriate. The contractual term excludes expected extensions, renewals, and modifications. Also included in the allowance for credit losses on loans are qualitative reserves to cover losses that are expected but, in the Company’s assessment, may not be adequately represented in the quantitative analysis described above. Factors that the Company considers include changes in lending policies and procedures, changes in management, changes in the quality of the loan review process, the existence of any concentrations of credit and other external factors. Individually Evaluated Loans On a case-by-case basis, the Company may conclude that a loan should be evaluated on an individual basis based on its disparate risk characteristics. The Bank has determined that any loans currently on nonaccrual status or are 90 or more days past due and still accruing are considered impaired and should be individually evaluated for losses. When the Company determines that a loan no longer shares similar risk characteristics with other loans in the portfolio, the allowance will be determined on an individual basis using the present value of expected cash flows or, for collateral-dependent loans, the fair value of the collateral as of the reporting date, less estimated selling costs, as applicable. If the fair value of the collateral is less than the amortized cost basis of the loan, the Company will establish a reserve for the difference between the fair value of the collateral, less costs to sell and carrying costs at the reporting date and the amortized cost basis of the loan. If this amount is deemed uncollectible, the Company will charge-off that amount. Acquired Loans Acquired loans are included in the Company's calculation of the allowance for credit losses. How the allowance on an acquired loan is recorded depends on whether or not it has been classified as a Purchased Credit Deteriorated (“PCD”) loan. PCD loans are loans acquired at a discount that is due, in part, to credit quality. PCD loans are accounted for in accordance with ASC Subtopic 326-20 and are initially recorded at fair value as determined by the sum of the present value of expected future cash flows and an allowance for credit losses at acquisition. The allowance for PCD loans is recorded through a gross-up effect, while the allowance for acquired non-PCD loans is recorded through provision expense, consistent with originated loans. Thus, the determination of which loans are PCD and non-PCD can have a significant impact on the accounting for these loans. Subsequent to acquisition, the allowance for PCD loans will generally follow the same estimation, provision and charge-off process as non-PCD acquired and originated loans. Under FASB ASC Topic 326, a PCD asset is defined as an individual financial asset that as of the date of acquisition has experienced a more than insignificant deterioration in credit quality since origination as determined during the acquisition process. Upon identification of these assets, the amortized cost basis will be adjusted at the time of acquisition to reflect any impairment amount. After acquisition, PCD loans will be either collectively evaluated for reserve requirements or individually evaluated if on nonaccrual status or are 90 or more days past due and still accruing. Allowance for Credit Losses on Off-Balance Sheet Commitments The Company is required to include unfunded commitments that are expected to be funded in the future within the allowance calculation, other than those that are unconditionally cancelable. To arrive at that reserve, the reserve percentage for each applicable segment is applied to the unused portion of the expected commitment balance and is multiplied by the expected funding rate. To determine the expected funding rate, the Company uses a historical utilization rate for each segment. As noted above, the allowance for credit losses on unfunded loan commitments is included in other liabilities on the consolidated balance sheets and the related credit expense is recorded in other non-interest expense in the consolidated statements of income and comprehensive income (loss). Allowance for Credit Losses on Held to Maturity Securities The Company’s portfolio of held to maturity securities consists of municipal bonds and U.S. agency residential mortgage-backed securities which are highly rated by major rating agencies and have a long history of no credit losses. In estimating the net amount expected to be collected for held to maturity securities in an unrealized loss position, a historical loss based method is utilized. Allowance for Credit Losses on Available for Sale Securities For available for sale securities in an unrealized loss position, the Company first assesses whether it intends to sell, or it is more likely than not that it will be required to sell the security before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the security’s amortized cost basis is written down to fair value through income. For securities available for sale that do not meet the above criteria, the Company evaluates whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, the Company considers the extent to which fair value is less than amortized cost, any changes to the rating by a rating agency, and adverse conditions related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. If the present value of the cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for credit losses is recorded for the credit loss, limited by the amount that the fair value is less than the amortized cost. Any impairment that has not been recorded through an allowance for credit losses is recognized in other comprehensive income, net of tax. The Company elected the practical expedient of zero loss estimates for securities issued by U.S. government entities and agencies. These securities are either explicitly or implicitly guaranteed by the U.S. government, are highly rated by major agencies and have a long history of no credit losses. Accrued Interest Receivable The Company made an accounting policy election to exclude accrued interest receivable from the amortized cost basis of loans, available for sale securities, and held to maturity securities. Accrued interest receivable on loans is reported as a component of accrued interest receivable on the Consolidated Balance Sheets, totaled $9.7 million at June 30, 2023 and is excluded from the estimate of credit losses. Accrued interest receivable on available for sale securities and held to maturity securities, also a component of accrued interest receivable on the Consolidated Balance Sheets, and totaled $1.5 million and $198 thousand, respectively, at June 30, 2023 and is excluded from the estimate of credit losses. Recent accounting standards 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 the Company 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 the Company’s annual report on Form 10-K for the year ended December 31, 2022. 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 the Company’s consolidated financial statements. ASU 2023-01, “Leases (Topic 842) - Common Control Arrangements” (ASU 2023-01) requires entities to determine whether a related party arrangement between entities under common control is a lease. If the arrangement is determined to be a lease, an entity must classify and account for the lease on the same basis as an arrangement with an unrelated party (on the basis of legally enforceable terms and conditions). ASU 2023-01 is effective January 1, 2024 and is not expected to have an impact on our financial statements. ASU 2023-02 “Investments - Equity Method and Joint Ventures (Topic 323) - Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method” (ASU 2023-02) permits reporting entities to elect to account for their tax equity investments, regardless of the tax credit program from which the income tax credits are received, using the proportional amortization method if certain conditions are met. ASU 2023-02 is effective January 1, 2024 and is not expected to have an impact on our financial statements.
