1. | Description of Business

NBT Bancorp Inc. (the “Company”) is a registered financial holding company incorporated in the state of Delaware in 1986, with its principal headquarters located in Norwich, New York. The principal assets of the Company consist of all of the outstanding shares of common stock of its subsidiaries, including: NBT Bank, National Association (the “Bank”), NBT Financial Services, Inc.

2. | Summary of Significant Accounting Policies

Basis of Presentation
The accompanying unaudited interim consolidated financial statements include the accounts of NBT Bancorp Inc. and its wholly-owned subsidiaries, the Bank, NBT Financial and NBT Holdings. Collectively, NBT Bancorp Inc. and its subsidiaries are referred to herein as (“the Company”). The interim data includes all adjustments, consisting only of normal recurring adjustments, necessary for a fair statement of the results for the interim periods in accordance with generally accepted accounting principles in the United States of America (“GAAP”). These unaudited interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s 2020 Annual Report on Form 10-K. The results of operations for the interim periods are not necessarily indicative of the results that may be expected for the full year or any other interim period. All material intercompany transactions have been eliminated in consolidation. Amounts previously reported in the consolidated financial statements are reclassified whenever necessary to conform to current period presentation. The Company has evaluated subsequent events for potential recognition and/or disclosure and there were none identified.
Use of Estimates in the Preparation of Financial Statements
The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts in the financial statements and accompanying notes. Actual results may differ from those estimates and such differences could be material to the financial statements.

3. | Recent Accounting Pronouncements

Recently Adopted Accounting Standards
In December 2019, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Updates (“ASU”) 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. This ASU removes specific exceptions to the general principles in Topic 740 in GAAP. It eliminates the need for an organization to analyze whether the following apply in a given period: (1) exception to the incremental approach for intraperiod tax allocation; (2) exceptions to accounting for basis differences when there are ownership changes in foreign investments; and (3) exception in interim period income tax accounting for year-to-date losses that exceed anticipated losses. The ASU also improves financial statement preparers’ application of income tax-related guidance and simplifies GAAP for: (1) franchise taxes that are partially based on income; (2) transactions with a government that result in a step up in the tax basis of goodwill; (3) separate financial statements of legal entities that are not subject to tax; and (4) enacted changes in tax laws in interim periods. The amendments in this ASU were effective for the Company on January 1, 2021, and interim periods within those fiscal years. The adoption did not have a material impact on the consolidated financial statements and related disclosures.

Table of Contents
Accounting Standards Issued Not Yet Adopted
In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. On January 7, 2021, the FASB issued ASU 2021-01, which refines the scope of Accounting Standards Codification 848 (“ASC 848”) and clarifies some of its guidance. ASU 2020-04 and related amendments provide temporary optional expedients and exceptions to the existing guidance for applying GAAP to affected contract modifications and hedge accounting relationships in the transition away from the London Interbank Offered Rate (“LIBOR”) or other interbank offered rate on financial reporting. The guidance also allows a one-time election to sell and/or reclassify to available for sale (“AFS”) or trading held to maturity (“HTM”) debt securities that reference an interest rate affected by reference rate reform. The amendments in this ASU are effective March 12, 2020 through December 31, 2022 and permits relief solely for reference rate reform actions and permits different elections over the effective date for legacy and new activity. The Company is evaluating the impact of adopting the new guidance on the consolidated financial statements and does not expect it will have a material impact on the consolidated financial statements.

The Company does not believe the AFS securities that were in an unrealized loss position as of March 31, 2021 and December 31, 2020, which consisted of 83 and 23 individual securities, respectively, represented a credit loss impairment. AFS debt securities in unrealized loss positions are evaluated for impairment related to credit losses at least quarterly. As of March 31, 2021 and December 31, 2020, the majority of the AFS securities in an unrealized loss position consisted of debt securities issued by U.S. government agencies or U.S. government-sponsored enterprises that carry the explicit and/or implicit guarantee of the U.S. government, which are widely recognized as “risk-free” and have a long history of zero credit losses. Total gross unrealized losses were primarily attributable to changes in interest rates, relative to when the investment securities were purchased, and not due to the credit quality of the investment securities. The Company does not intend to sell, nor is it more likely than not that the Company will be required to sell the security before recovery of its amortized cost basis, which may be at maturity. The Company elected to exclude accrued interest receivable (“AIR”) from the amortized cost basis of debt securities disclosed throughout this footnote. AIR on AFS debt securities totaled $3.2 million at March 31, 2021 and $3.3 million at December 31, 2020 and is excluded from the estimate of credit losses and reported in the financial statement line for other assets.

None of the bank’s HTM debt securities were past due or on non-accrual status as of March 31, 2021 and December 31, 2020. There was no accrued interest reversed against interest income for the three months ended March 31, 2021 or the year-ended December 31, 2020 as all securities remained on accrual status. In addition, there were no collateral-dependent HTM debt securities as of March 31, 2021 and December 31, 2020. As of March 31, 2021 and December 31, 2020, 59% and 65%, respectively, of the Company’s HTM debt securities were issued by U.S. government agencies or U.S. government-sponsored enterprises. These securities carry the explicit and/or implicit guarantee of the U.S. government, are widely recognized as “risk free,” and have a long history of zero credit loss. Therefore, the Company did not record an allowance for credit losses for these securities as of March 31, 2021 and December 31, 2020. The remaining HTM debt securities at March 31, 2021 and December 31, 2020 were comprised of state and municipal obligations with bond ratings of A to AAA. Utilizing the Current Expected Credit Losses (“CECL”) approach, the Company determined that the expected credit loss on its HTM municipal bond portfolio was immaterial and therefore no allowance for credit loss was recorded as of March 31, 2021 and December 31, 2020. AIR on HTM debt securities totaled $2.7 million at March 31, 2021 and December 31, 2020 and is excluded from the estimate of credit losses and reported in the other assets financial statement line.

5. | Allowance for Credit Losses and Credit Quality of Loans

The allowance for credit losses totaled $105.0 million at March 31, 2021, compared to $110.0 million at December 31, 2020. The allowance for credit losses as a percentage of loans was 1.38% at March 31, 2021, compared to 1.47% at December 31, 2020. The decrease in the allowance for credit losses from December 31, 2020 to March 31, 2021 was primarily due to the positive impact the improving economic conditions had on expected credit losses.
The Day 1 increase in the allowance for credit loss on loans relating to adoption of ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments was $3.0 million which decreased retained earnings by $2.3 million and increased the deferred tax asset by $0.7 million. The increase in the allowance for credit losses from Day 1 to March 31, 2020 was primarily due to macroeconomic factors surrounding the coronavirus (“COVID-19”) pandemic.
The March 31, 2021, December 31, 2020, March 31, 2020 and Day 1 allowance for credit losses calculation incorporated a 6-quarter forecast period to account for forecast economic conditions under each scenario utilized in the measurement. For periods beyond the 6-quarter forecast, the model reverts to long-term economic conditions over a 4-quarter reversion period on a straight-line basis. The Company considers a baseline, upside, and downside economic forecast in measuring in the allowance.
The quantitative model as of March 31, 2021 incorporated a baseline economic outlook along with an alternative downside scenario sourced from a reputable third-party to accommodate other potential economic conditions in the model. The baseline outlook reflected an unemployment rate environment above pre-COVID-19 levels for the entire forecast period, though steadily improving to below 5% by mid-2022. Northeast GDP’s annualized growth (on a quarterly basis) was expected to start 2021 in the low to mid-single digits, with a peak growth rate of 10% in the fourth quarter of 2021 and steadily falling back down to normalized levels through 2023. Other utilized economic variables also showed improvement in their respective forecasts. Key assumptions in the baseline economic outlook included herd immunity expected by summer 2021, additional legislation focused on infrastructure and social benefits enacted in the second half of 2021 and GDP growth expectations at levels not seen since the 1980s. The alternative downside scenario assumed deteriorated economic and epidemiological conditions from the baseline outlook, leading to a double-dip recession. The alternative upside scenario was not incorporated by management because of the underlying assumptions, forecasted economic data and modeled default rates. These scenarios and their respective weightings are evaluated at each measurement date and reflect management’s expectations as of March 31, 2021. Additional adjustments were made for COVID-19 related factors not incorporated in the forecasts, such as the mitigating impact of unprecedented stimulus in 2020 and 2021, including direct payments to individuals, increased unemployment benefits, the Company’s loan deferral and modification initiatives and various government-sponsored loan programs. Additionally, the Company identified a slightly higher level of criticized and classified loans at in the first quarter of 2021 than those contemplated by the model during similar economic conditions in the past for which an adjustment was made for estimated expected additional losses above modeled output. These factors were considered through a separate quantitative process and incorporated into the estimate for allowance for credit losses at March 31, 2021.
The quantitative model as of December 31, 2020 incorporated a baseline economic outlook, along with alternative upside and downside scenarios sourced from a reputable third-party to accommodate other potential economic conditions in the model. The baseline outlook reflected an unemployment rate environment above pre-COVID-19 levels for the entire forecast period, though steadily improving, before returning to low single digits by the end of 2023. Northeast GDP’s annual growth was expected to start 2021 in the low to mid-single digits, with a peak growth rate of 8% in the fourth quarter of 2021 and steadily falling back down to normalized levels through 2023 and 2024. Other utilized economic variables show improvement in their respective forecasts, namely business output. Key assumptions in the baseline economic outlook included an additional stimulus package passed at the same timing and a comparable level to that of the actual $900 billion COVID-19 relief package passed in December 2020 along with no significant secondary surge in COVID-19 cases or pandemic-related business closures. The alternative downside scenario assumed deteriorated economic and epidemiological conditions from the baseline outlook. In the same way, the alternative upside scenario assumed a faster economic recovery and more effective management of the COVID-19 virus from the baseline outlook. These scenarios and their respective weightings are evaluated at each measurement date and reflect management’s expectations as of December 31, 2020. Additional adjustments were made for COVID-19 related factors not incorporated in the forecasts, such as the mitigating impact of unprecedented stimulus in 2020, including direct payments to individuals, increased unemployment benefits, the Company’s loan deferral and modification initiatives and various government-sponsored loan programs. The commercial & industrial and consumer segment models were based upon percent change in unemployment with modeled values as of December 31, 2020 well outside the observed historical experience. Therefore, adjustments were required to produce outputs more aligned with default expectations given the forecast economic environment. Additionally, the Company identified a slightly higher level of criticized and classified loans during 2020 than those contemplated by the model during similar economic conditions in the past for which an adjustment was made for estimated expected additional losses above modeled output. These factors were considered through a separate quantitative process and incorporated into the estimate for allowance for credit losses at December 31, 2020.

There were no loans purchased with credit deterioration during the three months ended March 31, 2021 or the year ended December 31, 2020. During 2020, the Company purchased $51.9 million of consumer loans at a 1% discount. The allowance for credit losses recorded for these loans on the purchase date was $3.6 million. The Company made a policy election to report AIR in the other assets line item on the balance sheet. AIR on loans totaled $22.6 million at March 31, 2021 and $23.7 million at December 31, 2020 and was included in the allowance for loan credit losses to estimate the impact of accrued interest receivable related to loans with modifications due to the pandemic as the length of time between interest recognition and the write-off of uncollectible interest could exceed 120 days, exempting these loans from our policy election for accrued interest receivable. The estimated allowance for credit losses related to AIR at March 31, 2021 was $0.5 million and $0.6 million at December 31, 2020.

The decrease in the allowance for credit losses from December 31, 2020 to March 31, 2021 was primarily due to an improvement in the economic forecast. The increase in the allowance for credit losses from Day 1 to March 31, 2020 was primarily due to macroeconomic factors surrounding the COVID-19 pandemic.
Individually Evaluated Loans
As of March 31, 2021, there were five relationships identified to be evaluated for loss on an individual basis which had an amortized cost basis of $15.8 million. These loans’ allowance for credit loss was $3.9 million and was determined by an estimate of the fair value of the collateral which consisted of business assets (accounts receivable, inventory and machinery and equipment). As of December 31, 2020, the same five relationships were identified to be evaluated for loss on an individual basis which had an amortized cost basis of $15.2 million and the allowance for credit loss was $3.2 million. As of Day 1, there were no relationships identified to be evaluated for loss on an individual basis.

Credit Quality Indicators
The Company has developed an internal loan grading system to evaluate and quantify the Company’s loan portfolio with respect to quality and risk. The system focuses on, among other things, financial strength of borrowers, experience and depth of borrower’s management, primary and secondary sources of repayment, payment history, nature of the business and outlook on particular industries. The internal grading system enables the Company to monitor the quality of the entire loan portfolio on a consistent basis and provide management with an early warning system, enabling recognition and response to problem loans and potential problem loans.
Commercial Grading System
For Commercial and Industrial (“C&I”), Paycheck Protection Program (“PPP”) and Commercial Real Estate (“CRE”) loans, the Company uses a grading system that relies on quantifiable and measurable characteristics when available. This includes comparison of financial strength to available industry averages, comparison of transaction factors (loan terms and conditions) to loan policy and comparison of credit history to stated repayment terms and industry averages. Some grading factors are necessarily more subjective such as economic and industry factors, regulatory environment and management. C&I and CRE loans are graded Doubtful, Substandard, Special Mention and Pass.

Table of Contents
Doubtful
A Doubtful loan has a high probability of total or substantial loss, but because of specific pending events that may strengthen the asset, its classification as a loss is deferred. Doubtful borrowers are usually in default, lack adequate liquidity or capital and lack the resources necessary to remain an operating entity. Pending events can include mergers, acquisitions, liquidations, capital injections, the perfection of liens on additional collateral, the valuation of collateral and refinancing. Generally, pending events should be resolved within a relatively short period and the ratings will be adjusted based on the new information. Nonaccrual treatment is required for Doubtful assets because of the high probability of loss.
Substandard
Substandard loans have a high probability of payment default or they have other well-defined weaknesses. They require more intensive supervision by bank management. Substandard loans are generally characterized by current or expected unprofitable operations, inadequate debt service coverage, inadequate liquidity or marginal capitalization. Repayment may depend on collateral or other credit risk mitigants. For some Substandard loans, the likelihood of full collection of interest and principal may be in doubt and those loans should be placed on nonaccrual. Although Substandard assets in the aggregate will have a distinct potential for loss, an individual asset’s loss potential does not have to be distinct for the asset to be rated Substandard.
Special Mention
Special Mention loans have potential weaknesses that may, if not checked or corrected, weaken the asset or inadequately protect the Company’s position at some future date. These loans pose elevated risk, but their weakness does not yet justify a Substandard classification. Borrowers may be experiencing adverse operating trends (i.e., declining revenues or margins) or may be struggling with an ill-proportioned balance sheet (i.e., increasing inventory without an increase in sales, high leverage, tight liquidity). Adverse economic or market conditions, such as interest rate increases or the entry of a new competitor, may also support a Special Mention rating. Although a Special Mention loan has a higher probability of default than a Pass asset, its default is not imminent.
Pass
Loans graded as Pass encompass all loans not graded as Doubtful, Substandard or Special Mention. Pass loans are in compliance with loan covenants and payments are generally made as agreed. Pass loans range from superior quality to fair quality. Pass loans also include any portion of a government guaranteed loan, including PPP loans.
Consumer and Residential Grading System
Consumer and Residential loans are graded as either Nonperforming or Performing.
Nonperforming
Nonperforming loans are loans that are 1) over 90 days past due and interest is still accruing or 2) on nonaccrual status.
Performing
All loans not meeting any of the above criteria are considered Performing.

Troubled Debt Restructuring
When the Company modifies a loan in a troubled debt restructuring (“TDR”), such modifications generally include one or a combination of the following: an extension of the maturity date at a stated rate of interest lower than the current market rate for new debt with similar risk; temporary reduction in the interest rate; or change in scheduled payment amount. Residential and Consumer TDRs occurring during 2021 and 2020 were due to the reduction in the interest rate or extension of the term.
An allowance for impaired commercial and consumer loans that have been modified in a TDR is measured based on the present value of the expected future cash flows, discounted at the contractual interest rate of the original loan agreement, except when the sole (remaining) source of repayment for the loan is the operation or liquidation of the collateral. In these cases, management uses the current fair value of the collateral, less selling costs. If management determines that the value of the modified loan is less than the recorded investment in the loan an impairment charge would be recorded.
The Company began offering loan modifications to assist borrowers during the COVID-19 national emergency. The Coronavirus Aid, Relief and Economic Security Act (“CARES Act”), along with a joint agency statement issued by banking regulatory agencies, provides that modifications made in response to COVID-19 do not need to be accounted for as a TDR. The Company evaluated the modification programs provided to its borrowers and has concluded the modifications were generally made in accordance with the CARES Act guidance to borrowers who were in good standing prior to the COVID-19 pandemic and are not required to be designated as TDRs.
The following tables illustrate the recorded investment and number of modifications designated as TDRs, including the recorded investment in the loans prior to a modification and the recorded investment in the loans after restructuring:

6. | Defined Benefit Post-Retirement Plans

The Company has a qualified, noncontributory, defined benefit pension plan (“the Plan”) covering substantially all of its employees at March 31, 2021. Benefits paid from the Plan are based on age, years of service, compensation, social security benefits and are determined in accordance with defined formulas. The Company’s policy is to fund the Plan in accordance with Employee Retirement Income Security Act of 1974 standards. Assets of the Plan are invested in publicly traded stocks and mutual funds. In addition to the Plan, the Company provides supplemental employee retirement plans to certain current and former executives. The Company also assumed supplemental retirement plans for former executives of Alliance Financial Corporation (“Alliance”) when the Company acquired Alliance. These supplemental employee retirement plans and the Plan are collectively referred to herein as “Pension Benefits.”
In addition, the Company provides certain health care benefits for retired employees. Benefits were accrued over the employees’ active service period. Only employees that were employed by the Company on or before January 1, 2000 are eligible to receive post-retirement health care benefits. In addition, the Company assumed post-retirement medical life insurance benefits for certain Alliance employees, retirees and their spouses, if applicable, in the Alliance acquisition. These post-retirement benefits are referred to herein as “Other Benefits.”
The Company made no voluntary contributions to the pension and other benefits plans during the three months ended March 31, 2021 and 2020.
The components of expense for Pension Benefits and Other Benefits are set forth below:

|  | Pension Benefits |  |  | Other Benefits |

7. | Earnings Per Share

Basic earnings per share (“EPS”) excludes dilution and is computed by dividing income available to common stockholders by the weighted average number of common shares outstanding for the period. Diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the earnings of the entity (such as the Company’s dilutive stock options and restricted stock units).
The following is a reconciliation of basic and diluted EPS for the periods presented in the unaudited interim consolidated statements of income:

|  | Three Months Ended March 31, |
(In thousands, except per share data) |  | 2021 |  |  | 2020 |
Basic EPS: |  |  |  |  |  |
Weighted average common shares outstanding |  |  | 43,559 |  |  |  | 43,835 |
Net income available to common stockholders |  | $ | 39,846 |  |  | $ | 10,368 |
Basic EPS |  | $ | 0.91 |  |  | $ | 0.24 |
Diluted EPS: |  |  |  |  |  |  |  |
Weighted average common shares outstanding |  |  | 43,559 |  |  |  | 43,835 |
Dilutive effect of common stock options and restricted stock |  |  | 331 |  |  |  | 295 |
Weighted average common shares and common share equivalents |  |  | 43,890 |  |  |  | 44,130 |
Net income available to common stockholders |  | $ | 39,846 |  |  | $ | 10,368 |
Diluted EPS |  | $ | 0.91 |  |  | $ | 0.23 |

There was a nominal number of stock options outstanding for the three months ended March 31, 2021 and March 31, 2020, that were not considered in the calculation of diluted EPS since the stock options’ exercise prices were greater than the average market price during these periods.

9. | Derivative Instruments and Hedging Activities

The Company is exposed to certain risks 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, primarily by managing the amount, sources and duration of its assets and liabilities and through the use of derivative 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 derivative financial instruments are used to manage differences in the amount, timing and duration of the Company’s known or expected cash receipts and its known or expected cash payments principally related to certain fixed rate borrowings. The Company also has interest rate derivatives that result from a service provided to certain qualifying customers and, therefore, are not used to manage interest rate risk in the Company’s assets or liabilities. The Company manages a matched book with respect to its derivative instruments in order to minimize its net risk exposure resulting from such transactions.
Derivatives Not Designated as Hedging Instruments
The Company enters into interest rate swaps to facilitate customer transactions and meet their financing needs. These swaps are considered derivatives, but are not designated in hedging relationships. These instruments have interest rate and credit risk associated with them. To mitigate the interest rate risk, the Company enters into offsetting interest rate swaps with counterparties. The counterparty swaps are also considered derivatives and are also not designated in hedging relationships. Interest rate swaps are recorded within other assets or other liabilities on the consolidated balance sheet at their estimated fair value. Changes to the fair value of assets and liabilities arising from these derivatives are included, net, in other operating income in the consolidated statement of income.
The Company is subject to over-the-counter derivative clearing requirements, which require certain derivatives to be cleared through central clearing houses. Accordingly, the Company began to clear certain derivative transactions through the Chicago Mercantile Exchange Clearing House (“CME”) in January of 2021. This clearing house requires the Company to post initial and variation margin to mitigate the risk of non-payment, the latter of which is received or paid daily based on the net asset or liability position of the contracts. A daily settlement occurs through the CME for changes in the fair value of centrally cleared derivatives. Not all of the derivatives are required to be cleared through the daily clearing agent. As a result, the total fair values of loan level derivative assets and liabilities recognized on the Company’s financial statements are not equal and offsetting.
As of March 31, 2021 and December 31, 2020, the Company had seventeen risk participation agreements with financial institution counterparties for interest rate swaps related to participated loans. Risk participation agreements provide credit protection to the financial institution that originated the swap transaction should the borrower fail to perform on its obligation. The Company enters into both risk participation agreements in which it purchases credit protection from other financial institutions and those in which it provides credit protection to other financial institution s.
Derivatives Designated as Hedging Instruments
The Company has previously entered into interest rate swaps to modify the interest rate characteristics of certain short-term Federal Home Loan Bank (“FHLB”) advances from variable rate to fixed rate in order to reduce the impact of changes in future cash flows due to market interest rate changes. These agreements are designated as cash flow hedges.

(1)Netting adjustments represents the amounts recorded to convert derivatives assets and liabilities from a gross basis to a net basis in accordance with the applicable accounting guidance on the settle to market rules for cleared derivatives. The CME legally characterizes the variation margin posted between counterparties as settlements of the outstanding derivative contracts instead of cash collateral. Company began to clear certain derivative transactions through the CME in 2021.
(2)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 applicable accounting guidance. The other collateral consist of securities and 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 other collateral cannot reduce the net derivative position below zero. Therefore, excess other collateral, if any, is not reflected above.
For derivatives designated and that qualify as cash flow hedges of interest rate risk, the gain or loss on the derivative is recorded in AOCI and subsequently reclassified into interest expense in the same period during which the hedge transaction affects earnings. Amounts reported in AOCI related to derivatives will be reclassified to interest expense as interest payments are made on the Company’s short-term rate borrowings. During the three months ended March 31, 2021 the Company’s final cash flow hedge of interest rate risk matured and the renaming balance was reclassified from AOCI as a reduction to interest expense. There is no additional amount that will be reclassified from AOCI as a reduction to interest expense.

10. | Fair Value Measurements and Fair Value of Financial Instruments

GAAP states that fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. Fair value measurements are not adjusted for transaction costs. A fair value hierarchy exists within GAAP that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are described below:
Level 1 - Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities;
Level 2 - Quoted prices for similar assets or liabilities in active markets, quoted prices in markets that are not active or inputs that are observable, either directly or indirectly, for substantially the full term of the asset or liability; and
Level 3 - Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported by little or no market activity).
A financial instrument’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement.
The types of instruments valued based on quoted market prices in active markets include most U.S. government and agency securities, many other sovereign government obligations, liquid mortgage products, active listed equities and most money market securities. Such instruments are generally classified within Level 1 or Level 2 of the fair value hierarchy. The Company does not adjust the quoted prices for such instruments.
The types of instruments valued based on quoted prices in markets that are not active, broker or dealer quotations or alternative pricing sources with reasonable levels of price transparency include most investment-grade and high-yield corporate bonds, less liquid mortgage products, less liquid agency securities, less liquid listed equities, state, municipal and provincial obligations and certain physical commodities. Such instruments are generally classified within Level 2 of the fair value hierarchy. Certain common equity securities are reported at fair value utilizing Level 1 inputs (exchange quoted prices). Other investment securities are reported at fair value utilizing Level 1 and Level 2 inputs. The prices for Level 2 instruments are obtained through an independent pricing service or dealer market participants with whom the Company has historically transacted both purchases and sales of investment securities. Prices obtained from these sources include prices derived from market quotations and matrix pricing. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the bond’s terms and conditions, among other things. Management reviews the methodologies used in pricing the securities by its third party providers.
Level 3 is for positions that are not traded in active markets or are subject to transfer restrictions. Valuations are adjusted to reflect illiquidity and/or nontransferability and such adjustments are generally based on available market evidence. In the absence of such evidence, management’s best estimate will be used. Management’s best estimate consists of both internal and external support on certain Level 3 investments. Subsequent to inception, management only changes Level 3 inputs and assumptions when corroborated by evidence such as transactions in similar instruments, completed or pending third-party transactions in the underlying investment or comparable entities, subsequent rounds of financing, recapitalizations and other transactions across the capital structure, offerings in the equity or debt markets and changes in financial ratios or cash flows.

GAAP requires disclosure of assets and liabilities measured and recorded at fair value on a non-recurring basis such as goodwill, loans held for sale, other real estate owned, collateral-dependent impaired loans, mortgage servicing rights and HTM securities. The non-recurring fair value measurements recorded during the three month period ended March 31, 2021 and the year ended December 31, 2020 were related to impaired loans, write-downs of other real estate owned and write-down of branch assets to fair value. The Company uses the fair value of underlying collateral, less costs to sell, to estimate the allowance for credit losses for individually evaluated collateral dependent loans. The appraisals may be adjusted by management for qualitative factors such as economic conditions and estimated liquidation expenses ranging from 10% to 50%. Based on the valuation techniques used, the fair value measurements for collateral dependent individually evaluated loans are classified as Level 3.
As of March 31, 2021, the Company had collateral dependent individually evaluated loans with a carrying value of $15.8 million, which had an estimated allowance for credit loss of $3.9 million. As of December 31, 2020, the Company had collateral dependent individually evaluated loans with a carrying value of $15.2 million, which had an estimated allowance for credit loss of $3.2 million.

Fair value estimates are made at a specific point in time, based on relevant market information and information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale at one time the Company’s entire holdings of a particular financial instrument. Because no market exists for a significant portion of the Company’s financial instruments, fair value estimates are based on judgments regarding future expected loss experience, current economic conditions, risk characteristics of various financial instruments and other factors. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision. Changes in assumptions could significantly affect the estimates.
Fair value estimates are based on existing on and off-balance sheet financial instruments without attempting to estimate the value of anticipated future business and the value of assets and liabilities that are not considered financial instruments. For example, the Company has a substantial wealth operation that contributes net fee income annually. The wealth management operation is not considered a financial instrument and its value has not been incorporated into the fair value estimates. Other significant assets and liabilities include the benefits resulting from the low-cost funding of deposit liabilities as compared to the cost of borrowing funds in the market and premises and equipment. In addition, the tax ramifications related to the realization of the unrealized gains and losses can have a significant effect on fair value estimates and have not been considered in the estimate of fair value.
HTM Securities
The fair value of the Company’s HTM securities is primarily measured using information from a third-party pricing service. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the bond’s terms and conditions, among other things.
Net Loans
Net loans include portfolio loans and loans held for sale. Loans were first segregated by type and then further segmented into fixed and variable rate and loan quality categories. Expected future cash flows were projected based on contractual cash flows, adjusted for estimated prepayments, which also includes credit risk, illiquidity risk and other market factors to calculate the exit price fair value in accordance with ASC 820.
Time Deposits
The fair value of time deposits was estimated using a discounted cash flow approach that applies prevailing market interest rates for similar maturity instruments. The fair values of the Company’s time deposit liabilities do not take into consideration the value of the Company’s long-term relationships with depositors, which may have significant value.
Long-Term Debt
The fair value of long-term debt was estimated using a discounted cash flow approach that applies prevailing market interest rates for similar maturity instruments.
Subordinated Debt
The fair value of subordinated debt has been measured using the observable market price as of the period reported.
Junior Subordinated Debt
The fair value of junior subordinated debt has been estimated using a discounted cash flow analysis.

11. | Commitments and Contingencies

The Company is a party to certain financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit, unused lines of credit, standby letters of credit and certain agricultural real estate loans sold to investors with recourse, with the sold portion having a government guarantee that is assignable back to the Company upon repurchase of the loan in the event of default. The Company’s exposure to credit loss in the event of nonperformance by the other party to the commitments to extend credit, unused lines of credit, standby letters of credit and loans sold with recourse is represented by the contractual amount of those investments. The credit risk associated with commitments to extend credit and standby and commercial letters of credit is essentially the same as that involved with extending loans to customers and is subject to normal credit policies. Collateral may be obtained based on management’s assessment of the customer’s creditworthiness. Commitments to extend credit and unused lines of credit totaled $2.1 billion at March 31, 2021 and $2.2 billion at December 31, 2020.
Since many loan commitments, standby letters of credit and guarantees and indemnification contracts expire without being funded in whole or in part, the contract amounts are not necessarily indicative of future cash flows. The Company does not issue any guarantees that would require liability-recognition or disclosure, other than its standby letters of credit.
The Company guarantees the obligations or performance of customers by issuing standby letters of credit to third-parties. These standby letters of credit are generally issued in support of third-party debt, such as corporate debt issuances, industrial revenue bonds and municipal securities. The risk involved in issuing standby letters of credit is essentially the same as the credit risk involved in extending loan facilities to customers and letters of credit are subject to the same credit origination, portfolio maintenance and management procedures in effect to monitor other credit and off-balance sheet products. Typically, these instruments have one year expirations with an option to renew upon annual review; therefore, the total amounts do not necessarily represent future cash requirements. Standby letters of credit totaled $54.6 million at March 31, 2021 and $54.0 million at December 31, 2020. As of March 31, 2021 and December 31, 2020, the fair value of the Company’s standby letters of credit was not significant.

(“NBT”) and its wholly owned subsidiaries, including NBT Bank, National Association (the “Bank”), NBT Financial Services, Inc. (“NBT Financial”) and NBT Holdings, Inc. (“NBT Holdings”) (collectively referred to herein as the “Company”). This discussion will focus on results of operations, financial condition, capital resources and asset/liability management. Reference should be made to the Company’s consolidated financial statements and footnotes thereto included in this Form 10‑Q as well as to the Company’s Annual Report on Form 10‑K for the year ended December 31, 2020 for an understanding of the following discussion and analysis. Operating results for the three month period ending March 31, 2021 are not necessarily indicative of the results of the full year ending December 31, 2021 or any future period.
Forward-Looking Statements
Certain statements in this filing and future filings by the NBT Bancorp Inc. (the “Company”) with the Securities and Exchange Commission (“SEC”), in the Company’s press releases or other public or stockholder communications or in oral statements made with the approval of an authorized executive officer, contain forward-looking statements, as defined in the Private Securities Litigation Reform Act. These statements may be identified by the use of phrases such as “anticipate,” “believe,” “expect,” “forecasts,” “projects,” “will,” “can,” “would,” “should,” “could,” “may,” or other similar terms. There are a number of factors, many of which are beyond the Company’s control that could cause actual results to differ materially from those contemplated by the forward-looking statements. Factors that may cause actual results to differ materially from those contemplated by such forward-looking statements include, among others, the following possibilities: (1) local, regional, national and international economic conditions and the impact they may have on the Company and its customers and the Company’s assessment of that impact; (2) changes in the level of nonperforming assets and charge-offs; (3) changes in estimates of future reserve requirements based upon the periodic review thereof under relevant regulatory and accounting requirements; (4) the effects of and changes in trade and monetary and fiscal policies and laws, including the interest rate policies of the Federal Reserve Board (“FRB”); (5) inflation, interest rate, securities market and monetary fluctuations; (6) political instability; (7) acts of war or terrorism; (8) the timely development and acceptance of new products and services and perceived overall value of these products and services by users; (9) changes in consumer spending, borrowings and savings habits; (10) changes in the financial performance and/or condition of the Company’s borrowers; (11) technological changes; (12) acquisitions and integration of acquired businesses; (13) the ability to increase market share and control expenses; (14) changes in the competitive environment among financial holding companies; (15) the effect of changes in laws and regulations (including laws and regulations concerning taxes, banking, securities and insurance) with which the Company and its subsidiaries must comply, including those under the Dodd-Frank Act, Economic Growth, Regulatory Relief, Consumer Protection Act of 2018, Coronavirus Aid, Relief and Economic Security Act (“CARES Act”), and other legislative and regulatory responses to the coronavirus (“COVID-19”) pandemic; (16) the effect of changes in accounting policies and practices, as may be adopted by the regulatory agencies, as well as the Public Company Accounting Oversight Board, the Financial Accounting Standards Board (“FASB”) and other accounting standard setters; (17) changes in the Company’s organization, compensation and benefit plans; (18) the costs and effects of legal and regulatory developments including the resolution of legal proceedings or regulatory or other governmental inquiries and the results of regulatory examinations or reviews; (19) greater than expected costs or difficulties related to the integration of new products and lines of business; (20) the adverse impact on the U.S. economy, including the markets in which we operate, of the novel coronavirus, which causes COVID-19 global pandemic; and (21) the Company’s success at managing the risks involved in the foregoing items.

Table of Contents
Currently, one of the most significant factors that could cause actual outcomes to differ materially from the Company’s forward-looking statements is the potential adverse effect of the current COVID-19 pandemic on the financial condition, results of operations, cash flows and performance of the Company, its customers and the global economy and financial markets. The extent to which the COVID-19 pandemic impacts the Company will depend on future developments, which are highly uncertain and cannot be predicted with confidence, including the scope, severity and duration of the pandemic and its impact on the Company’s customers and demand for financial services, the actions governments, businesses and individuals take in response to the pandemic, the impact of the COVID-19 pandemic and actions taken in response to the pandemic on global and regional economies, national and local economic activity, the speed and effectiveness of vaccine and treatment developments and their deployment, including public adoption rates of COVID-19 vaccines, and the pace of recovery when the COVID-19 pandemic subsides, among others. Moreover, investors are cautioned to interpret many of the risks identified under the section entitled “Risk Factors” in our Form 10-K for the year ended December 31, 2020 as being heightened as a result of the ongoing and numerous adverse impacts of the COVID-19 pandemic.
The Company cautions readers not to place undue reliance on any forward-looking statements, which speak only as of the date made, and advises readers that various factors, including, but not limited to, those described above and other factors discussed in the Company’s annual and quarterly reports previously filed with the SEC, could affect the Company’s financial performance and could cause the Company’s actual results or circumstances for future periods to differ materially from those anticipated or projected.
Unless required by law, the Company does not undertake, and specifically disclaims any obligations to, publicly release any revisions that may be made to any forward-looking statements to reflect the occurrence of anticipated or unanticipated events or circumstances after the date of such statements.
Non-GAAP Measures
This Quarterly Report on Form 10-Q contains financial information determined by methods other than in accordance with accounting principles generally accepted in the United States of America (“GAAP”). Where non-GAAP disclosures are used in this Form 10-Q, the comparable GAAP measure, as well as a reconciliation to the comparable GAAP measure, is provided in the accompanying tables. Management believes that these non-GAAP measures provide useful information that is important to an understanding of the results of the Company’s core business as well as provide information standard in the financial institution industry. Non-GAAP measures should not be considered a substitute for financial measures determined in accordance with GAAP and investors should consider the Company’s performance and financial condition as reported under GAAP and all other relevant information when assessing the performance or financial condition of the Company.
Critical Accounting Policies
The Company has identified policies as being critical because they require management to make particularly difficult, subjective and/or complex judgments about matters that are inherently uncertain. The judgment and assumptions made are based upon historical experience or other factors that management believes to be reasonable under the circumstances. Because of the nature of the judgment and assumptions, actual results could differ from estimates, which could have a material effect on our financial condition and results of operations. These policies relate to the allowance for credit losses, pension accounting and provision for income taxes.
The allowance for credit losses consists of the allowance for credit losses and the allowance for losses on unfunded commitments. Measurement of Credit Losses on Financial Instruments (“CECL”) approach requires an estimate of the credit losses expected over the life of an exposure (or pool of exposures). The estimate of expected credit losses under the CECL approach is based on relevant information about past events, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amounts. Historical loss experience is generally the starting point for estimating expected credit losses. The Company then considers whether the historical loss experience should be adjusted for asset-specific risk characteristics or current conditions at the reporting date that did not exist over the period from which historical experience was used. Finally, the Company considers forecasts about future economic conditions that are reasonable and supportable. The allowance for losses on unfunded commitments represents the expected credit losses on off-balance sheet commitments such as unfunded commitments to extend credit and standby letters of credit. However, a liability is not recognized for commitments unconditionally cancellable by the Company. The allowance for losses on unfunded commitments is determined by estimating future draws and applying the expected loss rates on those draws.

Table of Contents
Management of the Company considers the accounting policy relating to the allowance for credit losses to be a critical accounting policy given the uncertainty in evaluating the level of the allowance required to cover management’s estimate of all expected credit losses over the expected contractual life of our loan portfolio. Determining the appropriateness of the allowance is complex and requires judgment by management about the effect of matters that are inherently uncertain. Subsequent evaluations of the then-existing loan portfolio, in light of the factors then prevailing, may result in significant changes in the allowance for credit losses in those future periods. While management’s current evaluation of the allowance for credit losses indicates that the allowance is appropriate, the allowance may need to be increased under adversely different conditions or assumptions. Going forward, the impact of utilizing the CECL approach to calculate the reserve for credit losses will be significantly influenced by the composition, characteristics and quality of our loan portfolio, as well as the prevailing economic conditions and forecasts utilized. Material changes to these and other relevant factors may result in greater volatility to the reserve for credit losses, and therefore, greater volatility to our reported earnings.
Management is required to make various assumptions in valuing the Company’s pension assets and liabilities. These assumptions include the expected rate of return on plan assets, the discount rate, the rate of increase in future compensation levels and interest rate of credit for cash balance plans. Changes to these assumptions could impact earnings in future periods. The Company takes into account the plan asset mix, funding obligations and expert opinions in determining the various rates used to estimate pension expense. The Company also considers market interest rates and discounted cash flows in setting the appropriate discount rate. In addition, the Company reviews expected inflationary and merit increases to compensation in determining the rate of increase in future compensation levels.
The Company is subject to examinations from various taxing authorities. Such examinations may result in challenges to the tax return treatment applied by the Company to specific transactions. Management believes that the assumptions and judgments used to record tax-related assets or liabilities have been appropriate. Should tax laws change or the taxing authorities determine that management’s assumptions were inappropriate, an adjustment may be required which could have a material effect on the Company’s results of operations.
The Company’s policies on the CECL method for allowance for credit losses, pension accounting and provision for income taxes are disclosed in Note 1 to the consolidated financial statements presented in our 2020 Annual Report on Form 10-K. All accounting policies are important and as such, the Company encourages the reader to review each of the policies included in Note 1 to the consolidated financial statements presented in our 2020 Annual Report on Form 10-K to obtain a better understanding of how the Company’s financial performance is reported. Refer to Note 3 to the unaudited interim consolidated finance statements in this Quarterly Report on Form 10-Q for recently adopted accounting standards.
Overview
Significant factors management reviews to evaluate the Company’s operating results and financial condition include, but are not limited to: net income and earnings per share, return on average assets and equity, net interest margin, noninterest income, operating expenses, asset quality indicators, loan and deposit growth, capital management, liquidity and interest rate sensitivity, enhancements to customer products and services, technology advancements, market share and peer comparisons. The Company’s results in 2020 and 2021 have been impacted by the COVID-19 pandemic and the CECL accounting methodology, including the estimated impact of the COVID-19 pandemic on expected credit losses. The following information should be considered in connection with the Company’s results for the three months ended March 31, 2021:

| ● | net income of $39.8 million, up $5.7 million from the fourth quarter of 2020 and up $29.5 million from the first quarter of 2020;

| ● | diluted earnings per share of $0.91, up $0.13 from the fourth quarter of 2020 and up $0.68 from the first quarter of 2020;

COVID-19 Pandemic and Company Response
The year 2020 began with overall stable U.S. economic conditions that were significantly impacted by the COVID-19 pandemic and subsequent shut-down of non-essential business throughout the Company’s footprint. A prolonged global pandemic like COVID-19 could adversely affect our operations. The results of operations and the ultimate effect of pandemic will depend on numerous factors that are highly uncertain including how long restrictions for business and individuals will last, further information around the severity of the virus itself, additional actions taken by federal, state and local governments to contain and treat COVID-19 and what, if any, additional government relief will be provided. The expected impact of the pandemic on the Company’s business, financial condition, results of operations, and its customers has not fully manifested. The fiscal stimulus and relief programs appear to have delayed any materially adverse financial impact to the Company. Once these stimulus programs have been exhausted, the Company’s credit metrics may worsen and loan losses could ultimately materialize. Any potential loan losses will be contingent upon the resurgence of the virus, including any new strains, offset by the potency of the vaccine along with its extensive distribution, and the ability for customers and businesses to return to their prepandemic routines. However, economic uncertainty remains relatively high and volatility is expected to continue in 2021.
In response, the Company immediately formed an Executive Task Force and engaged its established Incident Response Team under its Business Continuity Plan to execute a comprehensive pandemic response plan. The Company has taken significant steps to address the needs of its customers impacted by COVID-19. The Company provided payment relief for all its customers for 180 days or less, waiving associated late fees while not reporting these payment deferrals as late payments to the credit bureaus for all its consumer customers who were current prior to this event. The Company has also offered longer payment deferral options on a limited, case by case basis to address certain customers’ hardships related to the pandemic where we are able to gather information on the ongoing viability of the borrower’s long-term ability to return to full payment. The Company continues to responsibly lend to qualified consumer and commercial customers and designed special lending programs as well as participating in government sponsored relief programs to respond to customers’ needs during the pandemic. The Company believes our historically strong underwriting practices, diverse and granular portfolios, and geographic footprint will help to mitigate any adverse impact to the Company.
The Company has been a participant in the Small Business Administration’s Paycheck Protection Program (“PPP”), a loan guarantee program created under the CARES Act targeted to provide small businesses with support to cover payroll and certain other expenses. Loans made under the PPP are fully guaranteed by the Small Business Administration (“SBA”), whose guarantee is backed by the full faith and credit of the United States. PPP covered loans also afford borrowers forgiveness up to the principal amount of the PPP covered loan, plus accrued interest, if the loan proceeds are used to retain workers and maintain payroll or to make certain mortgage interest, lease and utility payments, and certain other criteria are satisfied. The SBA will reimburse PPP lenders for any amount of a PPP covered loan that is forgiven, and PPP lenders will not be held liable for any representations made by PPP borrowers in connection with their requests for loan forgiveness. Lenders receive pre-determined fees for processing and servicing PPP loans. In addition, PPP loans are risk-weighted at zero percent under the generally-applicable Standardized Approach used to calculate risk-weighted assets for regulatory capital purposes. The Company processed approximately 2,500 loans totaling $250 million in relief as of March 31, 2021 as compared to 3,000 loans totaling over $548 million in 2020. The Company is supporting PPP’s application and forgiveness processes with online resources, educational webinars and a CPA partnership. As of April 23, 2021, the Company has received payment from the SBA on 1,773 of our loans totaling $281.6 million.
On December 27, 2020, the President signed into law the Consolidated Appropriation Act (“CAA”). The CAA, among other things, extends the life of the PPP, effectively creating a second round of PPP loans for eligible businesses. The Company is participating in the CAA’s second round of PPP lending. In mid-January the Company opened its lending portal and began processing PPP loan applications from current and new customers. As of March 31, 2021, the Company has originated $250 million in PPP loans during this round with an average loan size of $99,000 and is continuing to receive applications.
The Company established a committee to ensure employee and customer safety and nimble response across geographic and functional areas. The five focus areas for the Company’s reopening are employee well-being, alternate work plans, physical workspace, working with customers and vendors, and policies, training and communication. The Committee monitored state and local responses and adapted physical locations across its footprint in its re-opening plans and will continue to monitor and adapt its response as the impact of COVID-19 continues to develop. The Company has taken significant actions to address the needs of employees and customers

Net Interest Income
Net interest income is the difference between interest income on earning assets, primarily loans and securities and interest expense on interest-bearing liabilities, primarily deposits and borrowings. Net interest income is affected by the interest rate spread, the difference between the yield on interest-earning assets and cost of interest-bearing liabilities, as well as the volumes of such assets and liabilities. Net interest income is one of the key determining factors in a financial institution’s performance as it is the principal source of earnings.
Net interest income was $79.1 million for the first quarter of 2021, down $1.1 million, or 1.3%, from the fourth quarter of 2020. The FTE net interest margin was 3.17% for the three months ended March 31, 2021, a decrease of 3 bps from the previous quarter. Interest income decreased $2.1 million, or 2.5%, as the yield on average interest-earning assets decreased 8 bps from the prior quarter to 3.38%, while average interest-earning assets of $10.1 billion increased $155.5 million from the prior quarter. Interest expense was down $1.1 million, or 17.0%, as the cost of interest-bearing liabilities decreased 6 bps to 0.34% for the quarter ended March 31, 2021, driven by interest-bearing deposit costs decreasing 5 bps along with decreased short-term and long-term borrowings cost.
Net interest income was $79.1 million for the first quarter of 2021, up $1.9 million, or 2.4%, from the first quarter of 2020. The FTE net interest margin of 3.17% was down 35 bps from the first quarter of 2020. Interest income decreased $5.1 million, or 5.7%, as the yield on average interest-earning assets decreased 69 bps from the same period in 2020, and average interest-earning assets increased $1.3 billion, or 14.4%, primarily due to higher levels of short-term interest bearing assets as deposit inflows from federal stimulus programs earning asset growth and an increase in average loans due to PPP loan originations. Interest expense decreased $7.0 million, or 57.0%, as the cost of interest-bearing liabilities decreased 48 bps, driven by interest-bearing deposit costs decreasing 48 bps along with a 110 bps decrease in short-term borrowings cost.

Excluding net securities gains (losses), noninterest income for the three months ended March 31, 2021 would have been $36.6 million, down $1.4 million, or 3.6% from the prior quarter and up $0.3 million, or 0.9% from the first quarter of 2020. Excluding net securities gains (losses), the decrease from the prior quarter was primarily driven by lower service charges on deposit accounts due to lower overdraft charges as customer average account balances have increased due to inflows of federal stimulus payments during the COVID-19 pandemic and lower swap fees, partly offset by an increase in retirement plan administration fees driven by market performance and organic growth. Excluding net securities gains (losses), the increase from the first quarter of 2020 was primarily due to an increase in retirement plan administration fees due to the April 1, 2020 acquisition of Alliance Benefit Group of Illinois, Inc. (“ABG”), and an increase in ATM and debit card fees due to increased volume and higher per transaction rates, partly offset by lower swap fees and lower mortgage banking income.

Noninterest expense for the three months ended March 31, 2021 was $67.9 million, down $7.3 million, or 9.7%, from the prior quarter and down $3.0 million, or 4.2%, from the first quarter of 2020. The decrease from the prior quarter was primarily due to $4.1 million in branch optimization costs incurred during the fourth quarter of 2020, a $1.4 million decrease in the provision for the reserve for unfunded commitments, lower professional fees and outside services due to timing of initiatives, partly offset by an increase in salaries and employee benefits expense driven by seasonally higher payroll taxes and stock-based compensation expense and an increase in data processing and communications driven by charges related to the addition of a digitized PPP platform. The decrease from the first quarter of 2020 was driven by decreases in other noninterest expense due to a $2.5 million decrease in the reserve for unfunded commitments, lower travel training expenses during the COVID-19 pandemic and lower pension costs, partly offset by an increase in salary and employee benefits expense due to the ABG acquisition and an increase in data processing and communications driven by charges related to the addition of a digitized PPP platform.
Income Taxes
Income tax expense for the three months ended March 31, 2021 was $11.2 million, up $1.7 million, from the prior quarter and up $9.4 million from the first quarter of 2020. The effective tax rate was 21.9% for the first quarter of 2021 compared to 21.6% for the fourth quarter of 2020 and 14.2% for the first quarter of 2020. The increase in income tax expense from the prior quarter and from the first quarter of 2020 was due to a higher level of taxable income.

(1) | Loans are summarized by business line which do not align to how the Company assesses credit risk in the estimate for credit losses under CECL.

Total loans increased $134.6 million, or 7.3% annualized from December 31, 2020 to March 31, 2021. Total PPP loans as of March 31, 2021 were $536.5 million (net of unamortized fees). The following PPP loan activity occurred during the first quarter of 2021: $250 million in PPP loan originations, $132.8 million of loans forgiven and $6.2 million of interest and fees recognized into interest income. Excluding PPP loans, period end loans increased $28.9 million from December 31, 2020. Commercial and industrial loans decreased $3.6 million to $1.3 billion; commercial real estate loans increased $57.5 million to $2.4 billion; and total consumer loans decreased $32.2 million to $3.4 billion. Total loans represented approximately 66.2% of assets as of March 31, 2021, as compared to 68.6% as of December 31, 2020.
Allowance for Credit Losses, Provision for Loan Losses and Nonperforming Assets
Management considers the accounting policy relating to the allowance for credit losses to be a critical accounting policy given the degree of judgment exercised in evaluating the level of the allowance required to estimate expected credit losses over the expected contractual life of our loan portfolio and the material effect that such judgments can have on the consolidated results of operations.
38

Table of Contents
Required additions or reductions to the allowance for credit losses are made periodically by charges or credits to the provision for loan losses. These are necessary to maintain the allowance at a level which management believes is reasonably reflective of the overall loss expected over the contractual life of the loan portfolio. While management uses available information to recognize losses on loans, additions or reductions to the allowance may fluctuate from one reporting period to another. These fluctuations are reflective of changes in risk associated with portfolio content and/or changes in management’s assessment of any or all of the determining factors discussed above. Management considers the allowance for credit losses to be appropriate based on evaluation and analysis of the loan portfolio.
The allowance for credit losses totaled $105.0 million at March 31, 2021, compared to $110.0 million at December 31, 2020 and $100.0 million at March 31, 2020. The allowance for credit losses as a percentage of loans was 1.38% (1.48% excluding PPP loans) at March 31, 2021, compared to 1.47% (1.56% excluding PPP loans) at December 31, 2020 and 1.38% at March 31, 2020. The decrease in the allowance for credit losses from December 31, 2020 to March 31, 2021 was primarily due to the improved economic conditions in the CECL forecast. The increase in the allowance for credit losses from March 31, 2020 was primarily due to specific allowance for credit losses on individually analyzed credits.
The provision for loan losses was ($2.8) million for three months ended March 31, 2021, compared to ($0.6) million in the prior quarter and $29.6 million for the same period in the prior year. Provision expense decreased from the prior quarter due to improved economic conditions in the CECL forecast. Provision expense decreased from the same period in the prior year due primarily to the improved economic condition forecast in the current quarter as compared to significant deterioration of the economic forecast that took place at the end of first quarter in 2020 due to COVID-19. Net charge-offs totaled $2.2 million during the three months ended March 31, 2021, compared to net charge-offs of $3.9 million during the fourth quarter of 2020 and $5.6 million in the first quarter of 2020.
As of March 31, 2021, the unfunded commitment reserve totaled $5.9 million, compared to $6.4 million as of December 31, 2020 and $5.7 million as of March 31, 2020. The decrease in the unfunded commitment reserve in 2021 compared to 2020 is primarily related to the improved economic conditions.
Nonperforming assets consist of nonaccrual loans, loans 90 days or more past due and still accruing, restructured loans, other real estate owned (“OREO”) and nonperforming securities. Loans are generally placed on nonaccrual when principal or interest payments become 90 days past due, unless the loan is well secured and in the process of collection. Loans may also be placed on nonaccrual when circumstances indicate that the borrower may be unable to meet the contractual principal or interest payments. The threshold for evaluating classified and nonperforming loans specifically evaluated for impairment is $1.0 million. OREO represents property acquired through foreclosure and is valued at the lower of the carrying amount or fair value, less any estimated disposal costs.

Allowance for credit losses to total nonperforming loans |  |  | 230.50 | % |  |  |  |  |  |  | 230.14 | % |  |  |  |

Total nonperforming assets were $46.9 million at March 31, 2021, compared to $49.3 million at December 31, 2020 and $34.6 million at March 31, 2020. Nonperforming loans at March 31, 2021 were $45.6 million, or 0.60%, of total loans (0.64% excluding PPP loan originations), compared with $47.8 million, or 0.64% of total loans (0.68% excluding PPP loan originations) and $32.3 million, or 0.45% at March 31, 2020.
The increase in nonperforming loans as compared to a year ago resulted primarily from five COVID-19 impacted commercial relationships totaling $15.8 million on non-accrual as of March 31, 2021. Past due loans as a percentage of total loans was 0.22% at March 31, 2021 (0.23% excluding PPP loan originations), down from 0.37% at December 31, 2020 (0.39% excluding PPP loan originations) and down from 0.51% at March 31, 2020.

The Company began offering short-term loan modifications to assist borrowers during the COVID-19 pandemic. The CARES Act, along with a joint agency statement issued by banking regulatory agencies, provides that short-term modifications made in response to COVID-19 do not need to be accounted for as a troubled debt restructuring (“TDR”). The Company evaluated the short-term modification programs provided to its borrowers and has concluded the modifications were generally made to borrowers who were in good standing prior to the COVID-19 pandemic and the modifications were temporary and minor in nature and therefore do not qualify for designation as TDRs. As of March 31, 2021, 1.0% of total loans outstanding (excluding PPP loan originations) were in payment deferral programs, of which 87% are commercial borrowers and 13% are consumer borrowers. As of December 31, 2020, 1.6% of total loans outstanding (excluding PPP loan originations) were in payment deferral programs, of which 80% were commercial borrowers and 20% were consumer borrowers.
In addition to nonperforming loans discussed above, the Company has also identified approximately $136.7 million in potential problem loans at March 31, 2021 as compared to $136.6 million at December 31, 2020. The increase in potential problem loans is primarily due to the Company’s proactive approach to risk ratings throughout the deferral process and relates to higher risk industries impacted by the COVID-19 pandemic. Higher risk industries include entertainment, restaurants, retail, healthcare and accommodations. As of March 31, 2021, 8.7% of the Company’s outstanding loans were in higher risk industries due to the COVID-19 pandemic. Potential problem loans are loans that are currently performing, with a possibility of loss if weaknesses are not corrected. Such loans may need to be disclosed as nonperforming at some time in the future. Potential problem loans are classified by the Company’s loan rating system as “substandard.” Management cannot predict the extent to which economic conditions may worsen or other factors, which may impact borrowers and the potential problem loans. Accordingly, there can be no assurance that other loans will not become 90 days or more past due, be placed on nonaccrual, become restructured or require increased allowance coverage and provision for loan losses. To mitigate this risk the Company maintains a diversified loan portfolio, has no significant concentration in any particular industry and originates loans primarily within its footprint.
Deposits
Total deposits were $9.8 billion at March 31, 2021, up $734.2 million, or 8.1%, from December 31, 2020. Total average deposits increased $1.6 billion, or 21.0%, from the same period last year. The growth was driven primarily by an increase of $920.7 million, or 38.4%, in demand deposits, combined with an increase in interest-bearing deposits of $699.6 million, or 13.2%, due to growth in money market deposit accounts (“MMDA”), NOW deposit accounts and savings deposit accounts, partly offset by a decrease in time accounts. The high rate of deposit growth was primarily due to funding of PPP loans and various government support programs.
Borrowed Funds
The Company’s borrowed funds consist of short-term borrowings and long-term debt. Short-term borrowings totaled $95.3 million at March 31, 2021 compared to $168.4 million at December 31, 2020. The notional value of interest rate swaps hedging cash flow related to short-term borrowings totaled $25.0 million at December 31, 2020 and matured during the three months ending March 31, 2021. Long-term debt was $14.1 million at March 31, 2021 and $39.1 million at December 31, 2020.
For more information about the Company’s borrowing capacity and liquidity position, see “Liquidity Risk” below.
Subordinated Debt
On June 23, 2020, the Company issued $100.0 million of 5.00% fixed-to-floating rate subordinated notes due 2030. The subordinated notes, which qualify as Tier 2 capital, bear interest at an annual rate of 5.00%, payable semi-annually in arrears commencing on January 1, 2021, and a floating rate of interest equivalent to the three-month Secured Overnight Financing Rate (“SOFR”) plus a spread of 4.85%, payable quarterly in arrears commencing on October 1, 2025. The subordinated debt issuance cost, which is being amortized on a straight-line basis, was $2.2 million. As of March 31, 2021 and December 31, 2020 the subordinated debt net of unamortized issuance costs was $98.2 million and $98.1 million, respectively.
Capital Resources
Stockholders’ equity of $1.2 billion represented 10.32% of total assets at March 31, 2021 compared with $1.2 billion, or 10.86% as of December 31, 2020. Stockholders’ equity was consistent with December 31, 2020 as net income of $39.8 million for the three months ending March 31, 2021 was offset by a decrease in accumulated other comprehensive income of $17.1 million, dividends declared of $11.7 million during the period and repurchase of common stock of $9.0 million.
The Company purchased 257,031 shares of common stock during the first quarter of 2021 at a weighted average price of $35.09 per share excluding commissions under a previously announced plan. As of March 31, 2021, there were 1,742,969 shares available for repurchase under this plan authorized on October 28, 2019, amended on January 27, 2021 and set to expire on December 31, 2021.

In March 2020, the Office of Comptroller of the Currency (“OCC”), the Board of Governors of the Federal Reserve System, and the Federal Deposit Insurance Corporation (“FDIC”)announced an interim final rule to delay the estimated impact on regulatory capital stemming from the implementation of CECL. Under the modified CECL transition provision, the regulatory capital impact of the January 1, 2020 CECL adoption date adjustment to the allowance for credit losses (after-tax) has been deferred and will phase into regulatory capital at 25% per year commencing January 1, 2022. For the ongoing impact of CECL, the Company is allowed to defer the regulatory capital impact of the allowance for credit losses in an amount equal to 25% of the change in the allowance for credit losses (pre-tax) recognized through earnings for each period between January 1, 2020 and December 31, 2021. The cumulative adjustment to the allowance for credit losses between January 1, 2020 and December 31, 2021, will also phase into regulatory capital at 25% per year commencing January 1, 2022. The Company adopted the capital transition relief over the permissible five-year period.

Liquidity and Interest Rate Sensitivity Management
Market Risk
Interest rate risk is the most significant market risk affecting the Company. Other types of market risk, such as foreign currency exchange rate risk and commodity price risk, do not arise in the normal course of the Company’s business activities or are immaterial to the results of operations.
Interest rate risk is defined as an exposure to a movement in interest rates that could have an adverse effect on the Company’s net interest income. Net interest income is susceptible to interest rate risk to the degree that interest-bearing liabilities mature or reprice on a different basis than earning assets. When interest-bearing liabilities mature or reprice more quickly than earning assets in a given period, a significant increase in market rates of interest could adversely affect net interest income. Similarly, when earning assets mature or reprice more quickly than interest-bearing liabilities, falling interest rates could result in a decrease in net interest income.
To manage the Company’s exposure to changes in interest rates, management monitors the Company’s interest rate risk. The Management’s Asset Liability Committee (“ALCO”) meets monthly to review the Company’s interest rate risk position and profitability and to recommend strategies for consideration by the Board of Directors. Management also reviews loan and deposit pricing and the Company’s securities portfolio, formulates investment and funding strategies and oversees the timing and implementation of transactions to assure attainment of the Board’s objectives in the most effective manner. Notwithstanding the Company’s interest rate risk management activities, the potential for changing interest rates is an uncertainty that can have an adverse effect on net income.
In adjusting the Company’s asset/liability position, the Board and management aim to manage the Company’s interest rate risk while minimizing net interest margin compression. At times, depending on the level of general interest rates, the relationship between long and short-term interest rates, market conditions and competitive factors, the Board and management may determine to increase the Company’s interest rate risk position somewhat in order to increase its net interest margin. The Company’s results of operations and net portfolio values remain vulnerable to changes in interest rates and fluctuations in the difference between long and short-term interest rates.
The primary tool utilized by the ALCO to manage interest rate risk is earnings at risk modeling (interest rate sensitivity analysis). Information, such as principal balance, interest rate, maturity date, cash flows, next repricing date (if needed) and current rates are uploaded into the model to create an ending balance sheet. In addition, the ALCO makes certain assumptions regarding prepayment speeds for loans and mortgage related investment securities along with any optionality within the deposits and borrowings. The model is first run under an assumption of a flat rate scenario (i.e. no change in current interest rates) with a static balance sheet. Three additional models are run in which a gradual increase of 200 bps, a gradual increase of 100 bps and a gradual decrease of 50 bps takes place over a 12-month period with a static balance sheet. Under these scenarios, assets subject to prepayments are adjusted to account for faster or slower prepayment assumptions. Any investment securities or borrowings that have callable options embedded in them are handled accordingly based on the interest rate scenario. The resulting changes in net interest income are then measured against the flat rate scenario. The Company also runs other interest rate scenarios to highlight potential interest rate risk.
In the declining rate scenario, net interest income is projected to decrease when compared to the forecasted net interest income in the flat rate scenario through the simulation period. The decrease in net interest income is a result of earning assets rolling over at lower yields while interest-bearing liabilities remain at or near their floors. In the rising rate scenarios, net interest income is projected to experience a modest increase from the flat rate scenario; however, the potential impact on earnings may be affected by the ability to lag deposit repricing on NOW, savings, MMDA and time accounts. Net interest income for the next twelve months in the +200/+100/-50 bp scenarios, as described above, is within the internal policy risk limits of not more than a 7.5% change in net interest income. The following table summarizes the percentage change in net interest income in the rising and declining rate scenarios over a 12-month period from the forecasted net interest income in the flat rate scenario using the March 31, 2021 balance sheet position:

Interest Rate Sensitivity Analysis Change in interest rates (In basis points) | Percent change in net interest income
+200 | 6.07%
+100 | 2.77%
-50 | (0.72%)

The Company anticipates that the trajectory of net interest income will depend significantly on the timing and path of the recovery from the recent economic downturn. In response to the economic impact of the pandemic, the federal funds rate was reduced by 150 bps in March 2020, and term interest rates fell sharply across the yield curve. The Company has reduced deposit rates, but future reductions are likely to be smaller and more selective. With deposit rates near their lower bound, the Company will focus on managing asset yields in order to maintain the net interest margin. Competitive pressure may limit the Company’s ability to maintain asset yields in the current environment, however.

Liquidity Risk
Liquidity involves the ability to meet the cash flow requirements of depositors wanting to withdraw funds or borrowers needing assurance that sufficient funds will be available to meet their credit needs. ALCO is responsible for liquidity management and has developed guidelines, which cover all assets and liabilities, as well as off-balance sheet items that are potential sources or uses of liquidity. Liquidity policies must also provide the flexibility to implement appropriate strategies, regular monitoring of liquidity and testing of the contingent liquidity plan. Requirements change as loans grow, deposits and securities mature and payments on borrowings are made. Liquidity management includes a focus on interest rate sensitivity management with a goal of avoiding widely fluctuating net interest margins through periods of changing economic conditions.
The primary liquidity measurement the Company utilizes is called “Basic Surplus,” which captures the adequacy of its access to reliable sources of cash relative to the stability of its funding mix of average liabilities. This approach recognizes the importance of balancing levels of cash flow liquidity from short and long-term securities with the availability of dependable borrowing sources, which can be accessed when necessary. At March 31, 2021, the Company’s Basic Surplus measurement was 29.4% of total assets or approximately $3.4 billion as compared to the December 31, 2020 Basic Surplus of 25.7% or $2.8 billion and which was above the Company’s minimum of 5% (calculated at $576.9 million and $546.6 million, of period end total assets at March 31, 2021 and December 31, 2020, respectively) set forth in its liquidity policies.
At March 31, 2021 and December 31, 2020, Federal Home Loan Bank (“FHLB”) advances outstanding totaled $14.1 million and $64.1 million, respectively. At March 31, 2021 and December 31, 2020, the Bank had $65.0 million and $74.0 million, respectively, of collateral encumbered by municipal letters of credit. The Bank is a member of the FHLB system and had additional borrowing capacity from the FHLB of approximately $1.7 billion at March 31, 2021 and $1.6 billion at December 31, 2020. In addition, unpledged securities could have been used to increase borrowing capacity at the FHLB by an additional $743.3 million and $839.4 million at March 31, 2021 and December 31, 2020, respectively, or used to collateralize other borrowings, such as repurchase agreements. The Company also has the ability to issue brokered time deposits and to borrow against established borrowing facilities with other banks (federal funds), which could provide additional liquidity of $1.9 billion at March 31, 2021 and $1.8 billion at December 31, 2020. In addition, the Bank has a “Borrower-in-Custody” program with the FRB with the addition of the ability to pledge automobile loans as collateral. At March 31, 2021 and December 31, 2020, the Bank had the capacity to borrow $619.2 million and $658.1 million, respectively, from this program. In addition, due to the creation of the Paycheck Protection Program Liquidity Facility during 2020, the Bank has the ability to borrow $568.5 million and $447.8 million through this program as of 568.5 and December 31, 2020, respectively. The Company’s internal policies authorize borrowings up to 25% of assets. Under this policy, remaining available borrowing capacity totaled $2.8 billion at March 31, 2021 and $2.6 billion at December 31, 2020.
This Basic Surplus approach enables the Company to appropriately manage liquidity from both operational and contingency perspectives. By tempering the need for cash flow liquidity with reliable borrowing facilities, the Company is able to operate with a more fully invested and, therefore, higher interest income generating securities portfolio. The makeup and term structure of the securities portfolio is, in part, impacted by the overall interest rate sensitivity of the balance sheet. Investment decisions and deposit pricing strategies are impacted by the liquidity position. The Company considered its Basic Surplus position to be strong. However, certain events may adversely impact the Company’s liquidity position in 2021. The large inflow of deposits experienced in the second quarter of 2020 could reverse itself and flow out. In the current economic environment, draws against lines of credit could drive asset growth higher. Disruptions in wholesale funding markets could spark increased competition for deposits. These scenarios could lead to a decrease in the Company’s Basic Surplus measure below the minimum policy level of 5%. Significant monetary and fiscal policy actions taken by the federal government have helped to mitigate these risks. Enhanced liquidity monitoring was put in place to quickly respond to the changing environment during the COVID-19 pandemic including increasing the frequency of monitoring and adding additional sources of liquidity.
At March 31, 2021, a portion of the Company’s loans and securities were pledged as collateral on borrowings. Therefore, once on-balance-sheet liquidity is depleted, future growth of earning assets will depend upon the Company’s ability to obtain additional funding, through growth of core deposits and collateral management and may require further use of brokered time deposits or other higher cost borrowing arrangements.
The Company’s primary source of funds is the Bank. Certain restrictions exist regarding the ability of the subsidiary bank to transfer funds to the Company in the form of cash dividends. The approval of the OCC is required to pay dividends when a bank fails to meet certain minimum regulatory capital standards or when such dividends are in excess of a subsidiary bank’s earnings retained in the current year plus retained net profits for the preceding two years as specified in applicable OCC regulations. At March 31, 2021, approximately $149.3 million of the total stockholders’ equity of the Bank was available for payment of dividends to the Company without approval by the OCC. The Bank’s ability to pay dividends is also subject to the Bank being in compliance with regulatory capital requirements. The Bank is currently in compliance with these requirements. Under the State of Delaware General Corporation Law, the Company may declare and pay dividends either out of accumulated net retained earnings or capital surplus.
