NICOLET BANKSHARES, INC.
Notes to Unaudited Consolidated Financial Statements

Note 1 – Basis of Presentation
General
In the opinion of management, the accompanying unaudited consolidated financial statements contain all adjustments necessary to present fairly the consolidated balance sheets, statements of income, comprehensive income, changes in stockholders’ equity and cash flows of Nicolet Bankshares, Inc. (the “Company” or “Nicolet”) and its subsidiaries, for the periods presented, and all such adjustments are of a normal recurring nature. All material intercompany transactions and balances have been eliminated. The results of operations for the interim periods are not necessarily indicative of the results to be expected for the entire year.
These interim consolidated financial statements have been prepared according to the rules and regulations of the Securities and Exchange Commission and, therefore, certain information and footnote disclosures normally presented in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) have been omitted or abbreviated. These consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and footnotes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019.
Critical Accounting Policies and Estimates
Preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying disclosures. These estimates are based on management’s best knowledge of current events and actions the Company may undertake in the future. Estimates are used in accounting for, among other items, the allowance for credit losses, valuation of loans in acquisition transactions, useful lives for depreciation and amortization, fair value of financial instruments, impairment calculations, valuation of deferred tax assets, uncertain income tax positions and contingencies. Estimates that are particularly susceptible to significant change for the Company include the determination of the allowance for credit losses, the determination and assessment of deferred tax assets and liabilities, and the valuation of loans acquired in acquisition transactions; therefore, these are critical accounting policies. Factors that may cause sensitivity to the aforementioned estimates include but are not limited to: external market factors such as market interest rates and employment rates, changes to operating policies and procedures, changes in applicable banking or tax regulations, and changes to deferred tax estimates. Actual results may ultimately differ from estimates, although management does not generally believe such differences would materially affect the consolidated financial statements in any individual reporting period presented.
There have been no material changes or developments with respect to the assumptions or methodologies that the Company uses when applying what management believes are critical accounting policies and developing critical accounting estimates as disclosed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019, except as disclosed in Updates to Significant Accounting Policies and Recent Accounting Developments Adopted below.
Updates to Significant Accounting Policies
Securities Available for Sale: Securities classified as AFS are those securities that the Company intends to hold for an indefinite period of time, but not necessarily to maturity. Any decision to sell a security classified as AFS would be based on various factors, including significant movements in interest rates, changes in the maturity mix of the Company’s assets and liabilities, liquidity needs, regulatory capital considerations, and other similar factors.

The Company evaluates securities AFS in unrealized loss positions on a quarterly basis to determine whether the decline in fair value below the amortized costs basis (impairment) is due to credit-related factors or noncredit-related factors. In making this evaluation, management considers the extent to which the fair value has been less than cost, the financial condition and near-term prospects of the issuer, and the intent and ability of the Company to hold the security for a period of time sufficient to allow for any anticipated recovery in fair value. Any impairment that is not credit-related is recognized in other comprehensive income, net of related deferred income taxes. Credit-related impairment is recognized as an allowance for credit losses (“ACL”) on the balance sheet based on the amount by which the amortized cost basis exceeds the fair value, with a corresponding charge to net income. Both the ACL and the charge to net income may be reversed if conditions change. However, if the Company intends to sell an impaired AFS security or more likely than not will be required to sell such a security before recovering its amortized cost basis, the entire impairment amount must be recognized in net income with a corresponding adjustment to the security's amortized cost basis rather than through the establishment of an ACL. See Note 5 for additional disclosures on AFS securities.

Loans – Originated: Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are carried at their amortized cost basis, which is the unpaid principal balance outstanding, net of deferred loan fees and costs and any direct principal charge-offs. The Company made an accounting policy election to exclude accrued interest from the amortized cost basis of loans and report such accrued interest as part of accrued interest receivable and other assets on the consolidated balance sheets.
8

Interest income is accrued on the unpaid principal balance using the simple interest method. The accrual of interest income on loans is discontinued when, in the opinion of management, there is reasonable doubt as to the borrower’s ability to meet payment of interest or principal when due. Loans are generally placed on nonaccrual status when contractually past due 90 days or more as to interest or principal, though may be placed in such status earlier based on the circumstances. Loans past due 90 days or more may continue on accrual only when they are well secured and/or in process of collection or renewal. When interest accrual is discontinued, all previously accrued but uncollected interest is reversed against current period interest income. Except in very limited circumstances, cash collections on nonaccrual loans are credited to the loan receivable balance and no interest income is recognized on those loans until the principal balance is paid in full. Accrual of interest may be resumed when the customer is current on all principal and interest payments and has been paying on a timely basis for a sustained period of time. See Note 6 for additional information and disclosures on loans.

Loans – Acquired: Loans purchased in acquisition transactions are acquired loans, and are recorded at their estimated fair value at the acquisition date.

Prior to January 1, 2020, as described in further detail in the Company’s 2019 Annual Report on Form 10-K, the Company initially classified acquired loans as either purchased credit impaired (“PCI”) loans (i.e., loans that reflect credit deterioration since origination and for which it is probable at acquisition that the Company will be unable to collect all contractually required payments) or purchased non-impaired loans (i.e., “performing acquired loans”). The Company estimated the fair value of PCI loans based on the amount and timing of expected principal, interest and other cash flows for each loan. The excess of the loan’s contractual principal and interest payments over all cash flows expected to be collected at acquisition was considered an amount that should not be accreted. These credit discounts (“nonaccretable marks”) were included in the determination of the initial fair value for acquired loans; therefore, no allowance for credit losses was recorded at the acquisition date. Differences between the estimated fair values and expected cash flows of acquired loans at the acquisition date that were not credit-based (“accretable marks”) were subsequently accreted to interest income over the estimated life of the loans. Subsequent to the acquisition date for PCI loans, increases in cash flows over those expected at the acquisition date resulted in a move of the discount from nonaccretable to accretable, while decreases in expected cash flows after the acquisition date were recognized through the provision for credit losses.

Subsequent to January 1, 2020, acquired loans that have evidence of more-than-insignificant deterioration in credit quality since origination are considered purchased credit deteriorated (“PCD”) loans. At acquisition, an estimate of expected credit losses is made for PCD loans. This initial allowance for credit losses is allocated to individual PCD loans and added to the purchase price or acquisition date fair value to establish the initial amortized cost basis of the PCD loans. Any difference between the unpaid principal balance of PCD loans and the amortized cost basis is considered to relate to noncredit factors, resulting in a discount or premium that is amortized to interest income. For acquired loans not deemed PCD loans at acquisition, the difference between the initial fair value mark and the unpaid principal balance are recognized in interest income over the estimated life of the loans. In addition, an initial allowance for expected credit losses is estimated and recorded as provision expense at the acquisition date. The subsequent measurement of expected credit losses for all acquired loans is the same as the subsequent measurement of expected credit losses for originated loans. See Note 6 for additional information and disclosures on loans.

Allowance for Credit Losses - Loans: The ACL-Loans represents management’s estimate of expected credit losses in the Company’s loan portfolio at the balance sheet date. The Company estimates the ACL-Loans based on the amortized cost basis of the underlying loan and has made an accounting policy election to exclude accrued interest from the loan’s amortized cost basis and the related measurement of the ACL-Loans. Estimating the amount of the ACL-Loans is a function of a number of factors, including but not limited to changes in the loan portfolio, net charge-offs, trends in past due and nonaccrual loans, and the level of potential problem loans, all of which may be susceptible to significant change.

Prior to January 1, 2020, as described in further detail in the Company’s 2019 Annual Report on Form 10-K, the Company used an incurred loss impairment model. This methodology assessed the overall appropriateness of the allowance for credit losses and included allocations for specifically identified impaired loans and loss factors for all remaining loans, with a component primarily based on historical loss rates and another component primarily based on other qualitative factors. Impaired loans were individually assessed and measured based on the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s observable market price or the fair value of the collateral if the loan was collateral dependent. Loans that were determined not to be impaired were collectively evaluated for impairment, stratified by type and allocated loss ranges based on the Company’s actual historical loss ratios for each strata, and adjustments were also provided for certain environmental and other qualitative factors.

Subsequent to January 1, 2020, the Company uses a current expected credit loss model (“CECL”). This methodology also considers historical loss rates and other qualitative adjustments, as well as a new forward-looking component that considers reasonable and supportable forecasts over the expected life of each loan. To develop the ACL-Loans estimate under the CECL
9

model, the Company segments the loan portfolio into loan pools based on loan type and similar credit risk elements; performs an individual evaluation of PCD loans; calculates the historical loss rates for the segmented loan pools; applies the loss rates over the calculated life of the pooled loans; adjusts for forecasted macro-level economic conditions; and determines qualitative adjustments based on factors and conditions unique to Nicolet's portfolio.

Recent Accounting Developments Adopted
In August 2018, the FASB issued Accounting Standards Update (“ASU”) 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement. This ASU modifies the disclosure requirements for fair value measurements by removing, modifying or adding certain disclosures. The updated guidance was effective for annual reporting periods, including interim periods within those fiscal years, beginning after December 15, 2019. The Company adopted the updated guidance effective January 1, 2020, with no material impact on its consolidated financial statements as the new ASU only revises disclosure requirements. See Note 9 for fair value disclosures.
In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments intended to improve the financial reporting by requiring earlier recognition of credit losses on loans and certain other financial assets. Topic 326 replaces the incurred loss impairment model (which recognizes losses when a probable threshold is met) with a requirement to recognize lifetime expected credit losses immediately when a financial asset is originated or purchased. The measurement of lifetime expected credit losses is based on historical experience, current conditions, and reasonable and supportable forecasts. The ASU was effective for SEC filers for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. The Company adopted the new accounting standard on January 1, 2020, as required, and recorded a cumulative-effect adjustment of $6 million to retained earnings. See Updates to Significant Accounting Policies above for changes to accounting policies and see Notes 5 and 6 for additional disclosures related to this new accounting pronouncement.
Reclassifications
Certain amounts in the 2019 consolidated financial statements have been reclassified to conform to the 2020 presentation.

Note 2 – Acquisitions
Completed Acquisitions:
Choice Bancorp, Inc. (“Choice”): On November 8, 2019, the Company consummated its merger with Choice, pursuant to the terms of the Agreement and Plan of Merger dated June 26, 2019, (the “Choice Merger Agreement”), whereby Choice (at 12% of Nicolet’s then pre-merger asset size) was merged with and into Nicolet, and Choice Bank, the wholly owned bank subsidiary of Choice, was merged with and into the Company's banking subsidiary, Nicolet National Bank (the “Bank”). The system integration was completed, and the two branches of Choice opened on November 12, 2019, as Nicolet National Bank branches, expanding its presence in the Oshkosh marketplace. The Company closed its legacy Oshkosh location concurrently with the consummation of the Choice merger.

The purpose of the merger was to continue Nicolet’s interest in strategic growth, consistent with its plan to improve profitability through efficiency, leverage the strengths of each bank across the combined customer base, and add shareholder value. With the merger, Nicolet became the leading community bank to serve the Oshkosh marketplace.
Pursuant to the Choice Merger Agreement, the final purchase price consisted of issuing 1,184,102 shares of the Company's common stock (given the final stock-for-stock exchange ratio of 0.497, and not exchanging the Choice shares owned by the Company immediately prior to the time of the merger), for common stock consideration of $79.8 million (based on $67.39 per share, the volume weighted average closing price of the Company's common stock over the preceding 30 trading day period) plus cash consideration of $1.7 million. Approximately $0.2 million in direct stock issuance costs for the merger were incurred and charged against additional paid-in capital.
Upon consummation, the Company added $457 million in assets, including $348 million in loans, $289 million in deposits, $1.7 million in core deposit intangible, and $45 million of goodwill. The Company accounted for the transaction under the acquisition method of accounting, and thus, the financial position and results of operations of Choice prior to the consummation date were not included in the accompanying consolidated financial statements. The accounting required assets purchased and liabilities assumed to be recorded at their respective estimated fair values at the date of acquisition.
Advantage Community Bancshares, Inc. (“Advantage”): On August 21, 2020, Nicolet completed its merger with Advantage, pursuant to the terms of the definitive merger agreement dated March 2, 2020, whereby Advantage merged with and into Nicolet, and Advantage Community Bank, the wholly owned bank subsidiary of Advantage, was merged with and into the Bank. Advantage's four branches in Dorchester, Edgar, Mosinee, and Wausau opened as Nicolet National Bank branches on August 24, 2020, expanding our presence in Central Wisconsin and the Wausau area. Due to the small size of the transaction, terms of the all-cash deal were not disclosed.
10

Upon consummation, Advantage added total assets of approximately $172 million (representing approximately 4% of Nicolet's then pre-merger asset size), loans of $88 million, deposits of $141 million, core deposit intangible of $1 million, and goodwill of $12 million.

Terminated Acquisition:
Commerce Financial Holdings, Inc. (“Commerce”): On February 17, 2020, Nicolet entered into a definitive merger agreement (“Merger Agreement”) with Commerce Financial Holdings, Inc. (“Commerce”) pursuant to which Nicolet would acquire Commerce and its wholly-owned banking subsidiary, Commerce State Bank. On May 18, 2020, Nicolet and Commerce announced a mutual agreement to terminate their Merger Agreement. Nicolet paid Commerce $0.5 million and surrendered its $0.1 million of Commerce common stock.

Note 3 – Earnings per Common Share
Basic earnings per common share are calculated by dividing net income available to common shareholders by the weighted average number of common shares outstanding during the period. Diluted earnings per common share are calculated by dividing net income available to common shareholders by the weighted average number of shares adjusted for the dilutive effect of common stock awards (outstanding stock options and unvested restricted stock), if any. Presented below are the calculations for basic and diluted earnings per common share.

Diluted earnings per common share*$1.72 $1.40 $3.97 $4.36 
*Cumulative quarterly per share performance may not equal annual per share totals due to the effects of the amount and timing of capital increases. When computing earnings per share for an interim period, the denominator is based on the weighted average shares outstanding during the interim period, and not on an annualized weighted average basis. Accordingly, the sum of the earnings per share data for the quarters will not necessarily equal the year to date earnings per share data.
For the three and nine months ended September 30, 2020, options to purchase approximately 0.2 million and 0.1 million shares, respectively, are excluded from the calculation of diluted earnings per common share as the effect of their exercise would have been anti-dilutive. For both the three and nine months ended September 30, 2019, options to purchase less than 0.1 million shares are excluded from the calculation of diluted earnings per common share as the effect of their exercise would have been anti-dilutive.

Note 4 – Stock-Based Compensation
The Company may grant stock options and restricted stock under its stock-based compensation plans to certain officers, employees and directors. These plans are administered by a committee of the Board of Directors, and at September 30, 2020, approximately 1.4 million shares were available for grant under these stock-based compensation plans.
A Black-Scholes model is utilized to estimate the fair value of stock option grants, while the market price of the Company’s stock at the date of grant is used to estimate the fair value of restricted stock awards. The weighted average assumptions used in the Black-Scholes model for valuing stock option grants were as follows.

In addition, during first nine months of 2020, the Company recognized approximately $0.4 million of director expense (included in other expense on the consolidated statements of income) for a total restricted stock grant of 7,950 shares with immediate vesting to directors, while during first nine months of 2019, the Company recognized approximately $0.3 million of director expense for a total restricted stock grant of 4,257 shares with immediate vesting to directors, representing the annual stock retainer fee paid to external board members. As of September 30, 2020, there was approximately $10.4 million of unrecognized compensation cost related to equity award grants. The cost is expected to be recognized over the remaining vesting period of approximately three years. The Company recognized a tax benefit of approximately $0.4 million and $1.0 million for the nine months ended September 30, 2020 and 2019, respectively, for the tax impact of stock option exercises and vesting of restricted stock.

The Company evaluates securities AFS in unrealized loss positions to determine whether the impairment is due to credit-related factors or noncredit-related factors. In making this evaluation, management considers the extent to which the fair value has been less than cost, the financial condition and near-term prospects of the issuer, and the intent and ability of the Company to hold the security for a period of time sufficient to allow for any anticipated recovery in fair value.
As of September 30, 2020, no allowance for credit losses on securities AFS was recognized. The Company does not consider its securities AFS with unrealized losses to be attributable to credit-related factors, as the unrealized losses in each category have occurred as a result of changes in noncredit-related factors such as changes in interest rates, market spreads and market conditions subsequent to purchase, not credit deterioration. Furthermore, the Company does not have the intent to sell any of these securities AFS and believes that it is more likely than not that we will not have to sell any such securities before a recovery of cost. During 2019, there were no other-than-temporary impairments charged to earnings.

The amortized cost and fair value of securities AFS by contractual maturity are shown below. Expected maturities may differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties; as this is particularly inherent in mortgage-backed securities, these securities are not included in the maturity categories below.

Accrued interest on loans totaled $8 million and $7 million at September 30, 2020 and December 31, 2019, respectively, and is included in accrued interest receivable and other assets on the consolidated balance sheets. See Note 1 for the Company's accounting policy on accrued interest with respect to loans and the allowance for credit losses.
Allowance for Credit Losses-Loans:
The majority of the Company’s loans, commitments, and letters of credit have been granted to customers in the Company’s market area. Although the Company has a diversified loan portfolio, the credit risk in the loan portfolio is largely influenced by general economic conditions and trends of the counties and markets in which the debtors operate, and the resulting impact on the operations of borrowers or on the value of underlying collateral, if any.

The ACL-Loans at September 30, 2020 was estimated using the current expected credit loss model. See Note 1 for the Company's accounting policy on loans and the allowance for credit losses.
The ACL-Loans represents management’s estimate of expected credit losses in the Company’s loan portfolio at the balance sheet date. To assess the appropriateness of the ACL-Loans, an allocation methodology is applied by Nicolet which focuses on evaluation of qualitative and environmental factors, including but not limited to: (i) evaluation of facts and issues related to specific loans; (ii) management’s ongoing review and grading of the loan portfolio; (iii) consideration of historical loan loss and delinquency experience on each portfolio segment; (iv) trends in past due and nonperforming loans; (v) the risk characteristics of the various loan segments; (vi) changes in the size and character of the loan portfolio; (vii) concentrations of loans to specific borrowers or industries; (viii) existing economic conditions; (ix) the fair value of underlying collateral; and (x) other qualitative and quantitative factors which could affect expected credit losses. Assessing these numerous factors involves significant judgment.
15

Management allocates the ACL-Loans by pools of risk within each loan portfolio segment. The allocation methodology consists of the following components. First, a specific reserve is established for individually evaluated credit-deteriorated loans, which management defines as nonaccrual credit relationships over $250,000, collateral dependent loans, and other loans with evidence of credit deterioration. The specific reserve in the ACL-Loans for these credit deteriorated loans is equal to the aggregate collateral or discounted cash flow shortfall. Management allocates the ACL-Loans with historical loss rates by loan segment. The loss factors are measured on a quarterly basis and applied to each loan segment based on current loan balances and projected for their expected remaining life. Next, management allocates the ACL-Loans using the qualitative factors mentioned above. Consideration is given to those current qualitative or environmental factors that are likely to cause estimated credit losses as of the evaluation date to differ from the historical loss experience of each loan segment. Lastly, management considers reasonable and supportable forecasts to assess the collectability of future cash flows.
A loan is considered to be collateral dependent when, based upon management's assessment, the borrower is experiencing financial difficulty and repayment is expected to be provided substantially through the operation or sale of the collateral. For collateral dependent loans, expected credit losses are based on the fair value of the collateral at the balance sheet date, with consideration for estimated selling costs if satisfaction of the loan depends on the sale of the collateral. The following table presents collateral dependent loans by portfolio segment and collateral type, including those loans with and without a related allowance allocation as of September 30, 2020.

An internal loan review function rates loans using a grading system based on different risk categories. Loans with a Substandard grade are considered to have a greater risk of loss and may be assigned allocations for loss based on specific review of the weaknesses observed in the individual credits. Such loans are constantly monitored by the loan review function to ensure early identification of any deterioration. A description of the loan risk categories used by the Company follows.
Grades 1-4, Pass: Credits exhibit adequate cash flows, appropriate management and financial ratios within industry norms and/or are supported by sufficient collateral. Some credits in these rating categories may require a need for monitoring but elements of concern are not severe enough to warrant an elevated rating.
Grade 5, Watch: Credits with this rating are adequately secured and performing but are being monitored due to the presence of various short-term weaknesses which may include unexpected, short-term adverse financial performance, managerial problems, potential impact of a decline in the entire industry or local economy and delinquency issues. Loans to individuals or loans supported by guarantors with marginal net worth or collateral may be included in this rating category.
Grade 6, Special Mention: Credits with this rating have potential weaknesses that, without the Company’s attention and correction may result in deterioration of repayment prospects. These assets are considered Criticized Assets. Potential weaknesses may include adverse financial trends for the borrower or industry, repeated lack of compliance with Company requests, increasing debt to net worth, serious management conditions and decreasing cash flow.
Grade 7, Substandard: Assets with this rating are characterized by the distinct possibility the Company will sustain some loss if deficiencies are not corrected. All foreclosures, liquidations, and nonaccrual loans are considered to be categorized in this rating, regardless of collateral sufficiency.
Troubled Debt Restructurings: At September 30, 2020, there were six loans classified as troubled debt restructurings with a current outstanding balance of $1.1 million and pre-modification balance of $1.9 million. In comparison, at December 31, 2019, there were five loans classified as troubled debt restructurings with an outstanding balance of $1.1 million and pre-modification balance of $1.4 million. There were no loans classified as troubled debt restructurings during the previous twelve months that
19

subsequently defaulted during the nine months ended September 30, 2020. As of September 30, 2020, there were no commitments to lend additional funds to debtors whose terms have been modified in troubled debt restructurings.

Note 7 – Goodwill and Other Intangibles and Mortgage Servicing Rights
Management periodically reviews the carrying value of its intangible assets to determine if any impairment has occurred, in which case an impairment charge would be recorded as an expense in the period of impairment, or whether changes in circumstances have occurred that would require a revision to the remaining useful life which would impact expense prospectively. In making such determination, management evaluates whether there are any adverse qualitative factors indicating that an impairment may exist, as well as the performance, on an undiscounted basis, of the underlying operations or assets which give rise to the intangible. In the first nine months of 2020, management considered the potential impacts of the COVID-19 pandemic on the valuation of our franchise value, stability of deposits, and of the wealth client base, underlying our goodwill, core deposit intangible, and customer list intangibles, and determined no impairments were indicated. However, the impacts of the COVID-19 pandemic, which began in March 2020, continue to evolve. The Company’s assessment in 2019 resulted in an $0.8 million full impairment charge on non-bank goodwill related to a change in business strategy. A summary of goodwill and other intangibles was as follows.

The Company periodically evaluates its mortgage servicing rights asset for impairment. At each reporting date, impairment is assessed based on estimated fair value using estimated prepayment speeds of the underlying mortgage loans serviced and stratifications based on the risk characteristics of the underlying loans (predominantly loan type and note interest rate). A valuation allowance of $0.8 million was recorded for the nine months ended September 30, 2020, while no valuation allowance was recorded for the year ended December 31, 2019. See Note 9 for additional information on the fair value of the MSR asset.
The following table shows the estimated future amortization expense for amortizing intangible assets and the MSR asset. The projections are based on existing asset balances, the current interest rate environment and prepayment speeds as of September 30, 2020. The actual amortization expense the Company recognizes in any given period may be significantly different depending upon acquisition or sale activities, changes in interest rates, prepayment speeds, market conditions, regulatory requirements and events or circumstances that indicate the carrying amount of an asset may not be recoverable.

PPPLF: To support the effectiveness of the PPP loans, the Federal Reserve introduced the PPPLF to extend credit to financial institutions that made PPP loans, with the related PPP loans used as collateral on the borrowings. The PPPLF borrowings have a fixed interest rate of 0.35% and a maturity date equal to the maturity date of the related PPP loans, with the PPP loans maturing either two or five years from the origination date of the PPP loan. The Company's PPP loans and related PPPLF funding have a weighted average life of approximately two years. Given the level of all other funding combined, the Company intends to repay the PPPLF during fourth quarter 2020.
FHLB Advances: The FHLB advances bear fixed rates, require interest-only monthly payments, and have maturity dates through 2027. The weighted average rate of the FHLB advances was 0.73% at September 30, 2020 and 1.57% at December 31, 2019.
Junior Subordinated Debentures: The following table shows the breakdown of junior subordinated debentures. Interest on all debentures is current. Any applicable discounts (initially recorded to carry an acquired debenture at its then estimated fair value) are being accreted to interest expense over the remaining life of the debentures. All the debentures below are currently callable and may be redeemed in part or in full at par plus any accrued but unpaid interest. The Company intends to redeem in full its 2004 Nicolet Bankshares Statutory Trust junior subordinated debentures ($6 million at 8%) on the next interest payment date of December 31, 2020, and has received all necessary regulatory approvals for such redemption. At September 30, 2020 and December 31, 2019, $29.8 million and $29.4 million, respectively, qualify as Tier 1 capital.

Subordinated Notes: In first half 2015, the Company placed an aggregate of $12 million in subordinated Notes in private placements with certain accredited investors. All Notes were issued with 10-year maturities, have a fixed annual interest rate of 5% payable quarterly, and may be called on or after the fifth anniversary of their respective issuances dates. The Company has received regulatory approval to call the Notes and has provided notice of its election to call all Notes effective November 16, 2020. The subordinated Notes qualify for Tier 2 capital for regulatory purposes, and are discounted in accordance with regulations when the debt has five years or less remaining to maturity.

Note 9 – Fair Value Measurements
Fair value represents the estimated price at which an orderly transaction to sell an asset or transfer a liability would take place between market participants at the measurement date under current market conditions (i.e., an exit price concept), and is a market-based measurement versus an entity-specific measurement.
The Company records and/or discloses financial instruments on a fair value basis. These financial assets and financial liabilities are measured at fair value in three levels, based on the markets in which the assets and liabilities are traded and the observability of the assumptions used to determine fair value. These levels are:
•Level 1 – quoted market prices in active markets for identical assets or liabilities that a company has the ability to access at the measurement date
•Level 2 – inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly
•Level 3 – significant unobservable inputs for the asset or liability, which are typically based on an entity’s own assumptions, as there is little, if any, related market activity
In instances where the fair value measurement is based on inputs from different levels, the level within which the entire fair value measurement will be categorized is based on the lowest level input that is significant to the fair value measurement in its entirety. This assessment of the significance of an input requires management judgment.

The following is a description of the valuation methodologies used by the Company for the securities AFS and equity securities measured at fair value on a recurring basis, noted in the tables above. Where quoted market prices on securities exchanges are available, the investments are classified as Level 1. Level 1 investments primarily include exchange-traded equity securities. If quoted market prices are not available, fair value is generally determined using prices obtained from independent pricing vendors who use pricing models (with typical inputs including benchmark yields, reported trades for similar securities, issuer spreads or relationship to other benchmark quoted securities), or discounted cash flows, and are classified as Level 2. Examples of these investments include U.S. government agency securities, mortgage-backed securities, obligations of state, county and municipals, and certain corporate debt securities. Finally, in certain cases where there is limited activity or less transparency around inputs to the estimated fair value, investments are classified within Level 3 of the hierarchy. Examples of these include private municipal bonds and corporate debt securities, which include trust preferred security investments. At September 30, 2020 and December 31, 2019, it was determined that carrying value was the best approximation of fair value for these Level 3 securities, based primarily on the internal analysis on these securities.
The following table presents the changes in the Level 3 securities AFS measured at fair value on a recurring basis.

MSR asset8,420 — — 8,420 
The following is a description of the valuation methodologies used by the Company for the items noted in the table above. For individually evaluated collateral dependent loans and impaired loans, the amount of impairment is based upon the present value of expected future cash flows discounted at the loan’s effective interest rate, the estimated fair value of the underlying collateral for collateral-dependent loans, or the estimated liquidity of the note. For OREO, the fair value is based upon the estimated fair value of the underlying collateral adjusted for the expected costs to sell. To estimate the fair value of the MSR asset, the underlying serviced loan pools are stratified by interest rate tranche and term of the loan, and a valuation model is used to calculate the present value of the expected future cash flows for each stratum. The valuation model incorporates assumptions that market participants would use in estimating future net servicing income, such as costs to service, a discount rate, ancillary income, default rates and losses, and prepayment speeds. Although some of these assumptions are based on observable market data, other assumptions are based on unobservable estimates of what market participants would use to measure fair value.

The carrying value of certain assets and liabilities such as cash and cash equivalents, BOLI, nonmaturing deposits, and short-term borrowings, approximate their estimated fair value. For those financial instruments not previously disclosed, the following is a description of the valuation methodologies used.
Certificates of deposits in other banks: Fair values are estimated using discounted cash flow analysis based on current interest rates being offered by instruments with similar terms and represents a Level 2 measurement.
Other investments: The valuation methodologies utilized for exchange-traded equity securities are discussed under “Recurring basis fair value measurements” above. The carrying amount of Federal Reserve Bank and FHLB stock is a reasonably accepted fair value estimate given their restricted nature. Fair value is the redeemable (carrying) value based on the redemption provisions of the instruments which is considered a Level 2 measurement. The carrying amount of the remaining other investments (particularly common stocks of companies or other banks that are not publicly traded) approximates their fair value, determined primarily by analysis of company financial statements and recent capital issuances of the respective companies or banks, if any, and represents a Level 3 measurement.
Loans held for sale: The fair value estimation process for the loans held for sale portfolio is segregated by loan type. The estimated fair value was based on what secondary markets are currently offering for portfolios with similar characteristics and represents a Level 2 measurement.
Loans, net: For variable-rate loans that reprice frequently and with no significant change in credit risk or other optionality, fair values are based on carrying values. Fair values for all other loans are estimated by discounting contractual cash flows using estimated market discount rates, which reflect the credit and interest rate risk inherent in the loan. Collateral-dependent impaired loans are included in loans, net. The fair value of loans is considered to be a Level 3 measurement due to internally developed discounted cash flow measurements.
Deposits: The fair value of deposits with no stated maturity (such as demand deposits, savings, interest and noninterest checking, and money market accounts) is, by definition, equal to the amount payable on demand at the reporting date. Fair values for fixed-rate certificates of deposit are estimated using a discounted cash flow calculation that applies interest rates currently being offered in the market place on certificates of similar remaining maturities. Use of internal discounted cash flows provides a Level 3 fair value measurement.
Long-term borrowings: The fair value of the FHLB advances is obtained from the FHLB which uses a discounted cash flow analysis based on current market rates of similar maturity debt securities and represents a Level 2 measurement. The PPPLF funding has a fixed rate of 0.35% for all participants; thus, carrying value approximates the estimated fair value and represents a Level 2 measurement. The fair values of the junior subordinated debentures and subordinated notes utilize a discounted cash flow analysis based on an estimate of current interest rates being offered by instruments with similar terms and credit quality. Since the market for these instruments is limited, the internal evaluation represents a Level 3 measurement.
Lending-related commitments and derivative financial instruments: At September 30, 2020 and December 31, 2019, the estimated fair value of letters of credit, interest rate lock commitments on residential mortgage loans, outstanding mandatory commitments to sell residential mortgage loans into the secondary market, and mirror interest rate swap agreements were not significant.
Limitations: 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. Fair value estimates may not be realizable in an
25

immediate settlement of the instrument. In some instances, there are no quoted market prices for the Company’s various financial instruments, in which case fair values may be based on estimates using present value or other valuation techniques, or based on judgments regarding future expected loss experience, current economic conditions, risk characteristics of the financial instruments, or other factors. Those techniques are significantly affected by the assumptions used, including the discount rate and estimate of future cash flows. Subsequent changes in assumptions could significantly affect the estimates.

Statements made in this document and in any documents that are incorporated by reference which are not purely historical are forward-looking statements, as defined in the Private Securities Litigation Reform Act of 1995, including any statements regarding descriptions of management’s plans, objectives, or goals for future operations, products or services, and forecasts of its revenues, earnings, or other measures of performance. Forward-looking statements are based on current management expectations and, by their nature, are subject to risks and uncertainties. These statements generally may be identified by the use of words such as “believe,” “expect,” “anticipate,” “plan,” “estimate,” “should,” “will,” “intend,” or similar expressions. Shareholders should note that many factors, some of which are discussed elsewhere in this document, could affect the future financial results of Nicolet and could cause those results to differ materially from those expressed in forward-looking statements contained in this document. These factors, many of which are beyond Nicolet’s control, include, but are not necessarily limited to the following:
•the effects of the COVID-19 pandemic on the business, customers, employees and third-party service providers of Nicolet or any of its acquisition targets;
•operating, legal and regulatory risks, including the effects of legislative or regulatory developments affecting the financial industry generally or Nicolet specifically;
•economic, market, political and competitive forces affecting Nicolet’s banking and wealth management businesses;
•changes in interest rates, monetary policy and general economic conditions, which may impact Nicolet’s net interest income;
•diversion of management time on pandemic-related issues;
•adoption of new accounting standards, including the effects from the adoption of the CECL model on January 1, 2020, or changes in existing standards;
•changes to statutes, regulations, or regulatory policies or practices resulting from the COVID-19 pandemic;
•compliance or operational risks related to new products, services, ventures, or lines of business, if any, that Nicolet may pursue or implement; and
•the risk that Nicolet’s analysis of these risks and forces could be incorrect and/or that the strategies developed to address them could be unsuccessful.
These factors should be considered in evaluating the forward-looking statements, and you should not place undue reliance on such statements. Nicolet specifically disclaims any obligation to update factors or to publicly announce the results of revisions to any of the forward-looking statements or comments included herein to reflect future events or developments.

Overview
The following discussion is management’s analysis of the consolidated financial condition as of September 30, 2020 and December 31, 2019 and results of operations for the three and nine-month periods ended September 30, 2020 and 2019. It should be read in conjunction with Nicolet’s audited consolidated financial statements included in Nicolet’s Annual Report on Form 10-K for the year ended December 31, 2019.

The timing of Nicolet’s acquisitions of Choice Bancorp, Inc. (“Choice”) on November 8, 2019, at 12% of pre-merger assets, and Advantage Community Bancshares, Inc. (“Advantage”) on August 21, 2020, at 4% of pre-merger assets, impacts financial comparisons. Certain income statement results, average balances and related ratios for the three and nine-month periods ended September 30, 2020 include full contribution from Choice and a partial period of Advantage in third quarter 2020, while the same periods in 2019 include no contribution from Choice or Advantage.
The World Health Organization declared the coronavirus COVID-19 a pandemic in March 2020. The initial impacts of the COVID-19 pandemic resulted in, among other things, stock and global markets decline, disruption in business and leisure activities as nation-wide stay-at-home orders were mandated, significant strain on the health care industry as it addressed the severity of the health crisis, and shift in the general economy (such as high unemployment, negative GDP expectations, a 150 bps decline in Federal funds rates, and unprecedented government stimulus), triggering a 2020 recession. The dramatic events surrounding the pandemic, fluctuating social and economic changes since the onset of the pandemic, and the uncertainty about the longevity of the pandemic's affects will continue to impact future expectations about credit costs and margins, as well as fee income and expenses.
27

Amid the uncertainty, Nicolet took action to increase liquidity (largely through procurement of term brokered CDs in late March to early April), significantly increased the credit loss provision in the first nine months of 2020 for the dramatically changed circumstances that continue to evolve, and recorded market losses on equity investments held (in response to the market decline). Initial actions to keep customers and employees safe included reducing on-site staff, increasing remote staff, segregating leadership and key functional departments (and adding redundancy to ensure continuity of operations should there be a COVID-19 related incident), limiting branch access through appointment-only lobbies and temporarily closing 11 locations. In second quarter 2020 we supplemented the pay of our front-line employees working on-site, eliminated senior management incentive accruals, and aggressively procured masks and other protective supplies. Costs associated with on-site bonuses, testing, and protective supplies totaled $0.6 million for second quarter 2020.
We sharpened our focus on configuring the Bank to more efficiently and effectively meet customers needs. We closely evaluated our branch network for redundancy and permanently closed seven (18%) of our 39 branches in second quarter, which also reduced headcount by 56 employees (nearly 10% of our workforce). As a result, $1.7 million of one-time costs were recorded during second quarter 2020 related to lease terminations, severance, accelerated depreciation and write-offs. At September 30, 2020, Nicolet operates 36 branches, which includes the four branches acquired with Advantage. During fourth quarter 2020, Nicolet plans to close its Rib Mountain location (near Wausau) and open an additional Appleton location that is currently under construction.
Given the extent of uncertainty, we guided numerous customers through new loans, temporary loan modifications, or participation in the Paycheck Protection Program (“PPP”). Through September 30, 2020, Nicolet originated $351 million of PPP loans for 2,725 business customers, which supported over 40,000 employees in those underlying businesses. The PPP loans provided low 1% coupon and potentially forgivable funds to small businesses, and are fully guaranteed by the SBA warranting no credit loss provision. Nicolet earned on average a 3.5% fee or $12.3 million gross from the SBA to process and service the PPP loans. This aggregate fee was deferred and will be accreted ratably into interest income over the life of the PPP loan pool, which may accelerate if loans payoff sooner. Nicolet recognized $2.7 million of the aggregate fee into interest income for year-to-date 2020. At September 30, 2020, the net carrying value of the PPP loans was $335 million. Using the PPP loans as collateral, Nicolet funded the PPP loans through the Federal Reserve's Paycheck Protection Program Liquidity Facility (“PPPLF”), which cost 0.35% and totaled $334 million at September 30, 2020. PPP loans are given a zero risk-weight in regulatory risk-based capital ratios and are also excluded from average assets in the regulatory leverage ratio if pledged as collateral on the related PPPLF funding. We created a micro-grant program, providing $1.25 million of funds in second quarter 2020 directly to 325 customers who otherwise qualified for a small PPP loan of less than $5,000, no strings attached, as a more cost beneficial, timely and impactful result for the customer and the Company. Since the pandemic started, payment modifications were made on approximately 980 loans totaling $462 million, most of which were commercial. As of September 30, only $60 million or 2% of loans excluding PPP loans, remained on modified terms. For retail customers purchasing new homes or refinancing, we closed over 1,200 mortgage loans in third quarter and nearly 3,300 for year-to-date 2020.
In summary, net income has been very strong at $42.1 million for the 2020 year-to-date period, despite the magnitude of unforeseen changes in the economy from the pandemic and other events. Most notably, exceptionally strong secondary mortgage income, steadily rising net interest income (despite tighter margins), and expense control (except for one-time costs of the second quarter) have supported earnings against elevated credit loss provisions for potential credit challenges which remain largely unseen and difficult to yet quantify. The 2020 balance sheet has continued to grow since year end 2019 to $4.7 billion in assets at September 30, 2020, in part from our recent acquisition, but more so from extraordinarily high cash attributable to strong deposit growth as customers remain focused on liquidity and safety.

Net income was $42.1 million for the nine months ended September 30, 2020, compared to $42.3 million for the nine months ended September 30, 2019. Earnings per diluted common share was $3.97 for the first nine months of 2020, compared to $4.36 for the first nine months of 2019.
•During second quarter 2019, net income favorably included $5.4 million (or $0.55 of diluted earnings per common share) related to two actions combined, the sale of 80% of Nicolet's equity investment in UFS, LLC, a data processing and e-banking entity ($7.4 million after-tax gain included in noninterest income under asset gains) and retirement-related compensation declared to benefit all employees after that sale ($2.75 million, or $2.0 million after-tax cost, included in noninterest expense under personnel), impacting the 2019 year-to-date and quarter comparisons.
•Net interest income was $95.3 million for the first nine months of 2020, up $9.7 million or 11% over the first nine months of 2019. Interest income grew $8.8 million attributable to favorable volumes (mostly higher loan volumes from the Choice acquisition in November 2019, PPP loans in second quarter 2020, the Advantage acquisition in August 2020, and higher cash), partly offset by net unfavorable rates, influenced by Federal Reserve rate cuts in late 2019 and again in March 2020. Interest expense favorably decreased $0.9 million between the nine-month periods with the impact of lower interest rates mostly offset by a higher volume of deposits. Net interest margin was 3.35% for the nine months ended September 30, 2020, compared to 4.17% for the nine months ended September 30, 2019, heavily influenced by the changing balance sheet mix in the lower rate environment. For additional information regarding net interest income, see “Income Statement Analysis — Net Interest Income.”
•Noninterest income was $45.7 million for the first nine months of 2020, up $5.7 million or 14% from the comparable 2019 period. Excluding net asset gains (losses), noninterest income was $46.9 million for the first nine months of 2020, up $14.9 million or 47% over 2019, predominantly on record net mortgage income spurred by strong refinance activity. For additional information regarding noninterest income, see “Income Statement Analysis — Noninterest Income.”
•Noninterest expense was $75.4 million, $4.0 million or 6% higher than the first nine months of 2019, largely due to the expanded operating base following the Choice and Advantage acquisitions, as well as one-time expenses in second quarter 2020 associated with the announced branch closures, safety efforts related to the pandemic, a micro-grant program and a merger termination charge (collectively $4.0 million), while second quarter 2019 included $2.75 million of nonrecurring retirement-related compensation declared. Personnel costs increased $1.1 million, and non-personnel expenses combined increased $2.9 million or 10% over the comparable 2019 period. For additional information regarding noninterest expense, see “Income Statement Analysis — Noninterest Expense.”
•Nonperforming assets were only $12 million, representing 0.25% of total assets at September 30, 2020, compared to 0.42% at December 31, 2019 and 0.34% at September 30, 2019. For additional information regarding nonperforming assets, see “Balance Sheet Analysis – Nonperforming Assets.”
•At September 30, 2020, assets were $4.7 billion, up $1.1 billion or 32% from December 31, 2019, largely due to higher cash and cash equivalents (commensurate with the increase in total deposits) and an increase in loans (driven by PPP loans originated in second quarter 2020), as well as the acquisition of Advantage, which added $172 million in assets, $88 million in loans and $141 million in deposits at acquisition. Compared to September 30, 2019, assets increased $1.6 billion or 52%, attributable to the noted increases since year-end 2019 as well as the acquisition of Choice, which added $457 million in assets, $348 million in loans and $289 million in deposits at acquisition. For additional balance sheet discussion see “Balance Sheet Analysis.”
•At September 30, 2020, loans were $2.9 billion, 13% higher than December 31, 2019 and 30% higher than September 30, 2019. On average, loans grew $565 million or 26% over the first nine months of 2019. For additional information regarding loans, see “Balance Sheet Analysis — Loans.”
•Total deposits were $3.7 billion at September 30, 2020, an increase of 26% from December 31, 2019 and 44% higher than September 30, 2019. Year-to-date average deposits were $776 million or 30% higher than the first nine months of 2019. For additional information regarding deposits, see “Balance Sheet Analysis – Deposits.”

INCOME STATEMENT ANALYSIS
Net Interest Income
Tax-equivalent net interest income is a non-GAAP measure, but is a preferred industry measurement of net interest income (and its use in calculating a net interest margin) as it enhances the comparability of net interest income arising from taxable and tax-exempt sources. The tax-equivalent adjustments bring tax-exempt interest to a level that would yield the same after-tax income by applying the effective Federal corporate tax rates to the underlying assets. Tables 2 and 3 present information to facilitate the review and discussion of selected average balance sheet items, tax-equivalent net interest income, interest rate spread and net interest margin.

The interest rate environment has experienced dramatic change. The Federal Reserve steadily raised short-term interest rates during 2017 and 2018 in support of a growing economy (up 175 bps total to 2.50% at year end 2018), and then reduced rates by 75 bps in three moves during the second half of 2019 (to 1.75% at year end 2019) largely responding to global issues and slowing growth, which contributed to a flattened yield curve with periods of inversion. In March 2020, the Federal Reserve dropped short-term rates by 150 bps (to 25 bps at March 31, 2020) in two emergency moves to respond to the unprecedented economic disruptions of the COVID-19 pandemic described in the “Overview” section, which brought slope back into the yield curve, though still fairly flat. Comparatively, short-term rates were 175 bps lower at September 30, 2020 than at September 30, 2019. While the following paragraphs will discuss the comparison of the nine months of 2020 and 2019, we expect that the COVID-19 pandemic impacts will continue to evolve and pressure future quarters even further, including continued margin pressure and potential unusual loan or deposit volume or pricing impacts.
Tax-equivalent net interest income was $96.0 million for the first nine months of 2020, comprised of net interest income of $95.3 million ($9.7 million or 11% higher than the first nine months of 2019), and a $0.7 million tax-equivalent adjustment (down nearly $0.1 million between the periods). The $9.6 million increase in tax-equivalent net interest income was attributable to net favorable volumes (which added $21.3 million, with $22.1 million from higher loan volumes, due to the inclusion of Choice and Advantage interest-earning assets, as well as PPP loans) and net unfavorable rates (which reduced net interest income by $11.7 million). The net $11.7 million decrease from rates was from interest-earning asset rate changes in the lower rate environment (decreasing net interest income by $16.6 million, of which $13.1 million was from loans, and $3.0 million was from the dramatically reduced cash rate earned), offset partly by benefits of a lower cost of funds (improving net interest income by $4.9 million, predominantly led by $5.3 million savings from non-brokered interest-bearing core deposits and $0.6 million savings from wholesale funds, partly offset by $1.0 million more interest cost from term brokered deposits which increased in both rate and volume).
33

Between the comparable nine-month periods, the interest rate spread decreased 71 bps, largely attributable to the lower interest rate environment between the periods and the significantly higher concentration of low-earning cash in the 2020 period. The 2020 interest earning asset yield declined 108 bps to 3.91%, largely from the 73 bps decline in loans (with approximately 16 bps related to inclusion of PPP loans at a 2.80% yield), and was also harmed by the decrease in the loans-to-earning asset mix (to 73% compared to 80% for the first nine months of 2019) given the significant increase in cash. The 2020 cost of funds declined favorably by 37 bps to 0.80%, largely from improved core deposit rates and lower variable wholesale funding rates, though offset partly by higher-costing brokered deposits (representing 10% of interest-bearing liabilities versus 3% for the first nine months of 2019) acquired with the Choice acquisition and procured in March-April 2020 under competitive conditions. The contribution from net free funds decreased 11 bps, due mostly to the reduced value in the lower rate environment, though offset partly by the 38% increase in average net free funds (largely from average noninterest-bearing demand deposits and stockholders equity) between the nine-month periods. As a result, the tax-equivalent net interest margin was 3.35% for the first nine months of 2020, down 82 bps compared to 4.17% for the comparable 2019 period.
Average interest-earning assets increased to $3.8 billion, up $1.0 billion (38%) over the 2019 comparable period, primarily due to the timing of the acquisitions (Choice in November 2019 and Advantage in August 2020), addition of PPP loans (beginning second quarter 2020), and significantly higher cash starting in second quarter 2020. Between the comparable nine-month periods, average loans increased $565 million or 26% (which includes modest organic growth, $348 million of Choice loans at acquisition, $88 million of Advantage loans at acquisition, and $335 million of net PPP loans at September 30, 2020), while all other interest-earning assets combined increased $470 million (87%) on average. The mix of average interest-earning assets shifted toward lower-yielding assets, at 73% loans, 13% investments and 14% other interest-earning assets (mostly cash) for the first nine months of 2020, compared to 80%, 15% and 5%, respectively for the first nine months of 2019.
Tax-equivalent interest income was $111.9 million for the first nine months of 2020, up $8.7 million (8%) over the first nine months of 2019, while the related interest-earning asset yield was 3.91%, down 108 bps from the comparable period in 2019. Interest income on loans increased $9.0 million (10%) over the first nine months of 2019, aided by strong volumes, including Choice, Advantage, and PPP loans. The 2020 loan yield was 4.85%, down 73 bps from the first nine months of 2019, largely from the significantly lower rate environment impacting yields on new, renewed and variable rate loans, as well as from inclusion of PPP loans at a 2.80% yield. Between the comparable nine-month periods, interest income on non-loan earning assets combined was down $0.3 million to $10.2 million, impacted by a 125 bps decline in the yield (to 1.35%) in the lower rate environment, partially offset by higher average volumes (up 87%) from the significantly higher cash.
Average interest-bearing liabilities were $2.6 billion, an increase of $721 million (38%), primarily due to the timing of the Choice acquisition in November 2019 and the Advantage acquisition in August 2020, as well as the significant increase in deposits from government stimulus activities and deposited PPP loan proceeds. The mix of average interest-bearing liabilities was 79% core deposits, 10% brokered deposits and 11% other funding, compared to 93%, 3% and 4%, respectively, for the first nine months of 2019, with the mix changes (especially increased money markets and brokered deposits) influenced by the mix of the $289 million of Choice deposits acquired, and the procurement of brokered deposits in March-April 2020 as part of previously discussed liquidity actions.
Interest expense decreased to $15.8 million (down $0.9 million) for the first nine months of 2020 compared to the first nine months of 2019, on larger average interest-bearing liabilities volumes (up 38% to $2.6 billion) but at a lower overall cost of funds (down 37 bps to 0.80%). Interest expense on deposits decreased $0.9 million (6%) from the first nine months of 2019 given 28% higher average interest-bearing deposit balances but at a lower cost (down 28 bps to 0.75%). The 2020 cost of savings, interest-bearing demand, money market accounts and core time deposits decreased from the first nine months of 2019, by 29 bps, 27 bps, 43 bps and 40 bps, respectively, as product rate changes were made in the lower rate environment, and brokered deposits cost 98 bps more than the comparable nine-month period of 2019, largely from higher-costing term brokered funds acquired with the Choice acquisition in November 2019 and procured during March-April 2020 under competitive conditions as part of previously discussed liquidity actions. Interest expense on other interest-bearing liabilities was minimally changed between the comparable nine-month periods, as additional interest expense on higher average balances (up $205 million) was substantially offset by lower rates (down 336 bps to 1.23%), mostly impacted by the inclusion of the low-costing PPPLF (average balance of $192 million for the first nine months of 2020 at a 0.35% rate), and variable rate debt repricing and maturing advances replaced in the lower rate environment.

Provision for Credit Losses
The provision for credit losses increased to $9.0 million for the nine months ended September 30, 2020, compared to $0.9 million for the nine months ended September 30, 2019, largely due to the unprecedented economic disruptions and uncertainty surrounding the COVID-19 pandemic, and to a lesser extent, to the acquisition of Advantage in third quarter 2020. The provision for credit losses was significantly increased to $3 million in first quarter 2020 with nearly no forward visibility in the wake of an emerging pandemic and recession. For second and third quarter 2020, the expectations about the extent and duration of current credit stress on our customers remains extremely difficult to estimate; thus, an additional provision of $3 million per quarter was provided despite no material degradation of the current asset quality metrics. In addition, the third quarter provision for credit losses included approximately $0.6 million to establish the initial allowance for credit losses - loans related to the Advantage acquisition.
The provision for credit losses is predominantly a function of Nicolet’s methodology and judgment as to qualitative and quantitative factors used to determine the appropriateness of the ACL-Loans. The appropriateness of the ACL-Loans is affected by changes in the size and character of the loan portfolio, changes in levels of impaired and other nonperforming loans, historical losses and delinquencies in each portfolio segment, the risk inherent in specific loans, concentrations of loans to specific borrowers or industries, existing and future economic conditions, the fair value of underlying collateral, and other factors which could affect expected credit losses. See also Note 1, “Basis of Presentation” and Note 6, “Loans, Allowance for Credit Losses - Loans, and Credit Quality” of the Notes to Unaudited Consolidated Financial Statements under Part I, Item 1, for additional policy and disclosures. For additional information regarding asset quality and the ACL-Loans, see “BALANCE SHEET ANALYSIS — Loans,” “— Allowance for Credit Losses - Loans,” and “— Nonperforming Assets.”

Noninterest income was $45.7 million for the first nine months of 2020, an increase of $5.7 million (14%) compared to $40.1 million for the comparable period of 2019, which included a $7.4 million gain on the equity investment sale noted previously. Noninterest income excluding net asset gains (losses) grew $14.9 million (47%) between the comparable nine-month periods, predominantly on strong net mortgage income.
Trust services fee income and brokerage fee income combined were $11.8 million, up $1.2 million (12%) over the first nine months of 2019, consistent with the growth in accounts and assets under management.
Mortgage income represents net gains received from the sale of residential real estate loans into the secondary market, capitalized mortgage servicing rights (“MSRs”), servicing fees net of MSR amortization, fair value marks on the mortgage interest rate lock commitments and forward commitments (“mortgage derivatives”), and MSR valuation changes, if any. Net mortgage income of $22.0 million, increased $15.0 million (215%) between the comparable nine-month periods, predominantly from higher sale gains and capitalized gains combined (up $15.3 million or 217%, commensurate with the increase in volumes sold into the secondary market aided by the current refinance boom and better pricing between the years), favorable changes in the fair value of the mortgage derivatives (up $0.3 million), and higher net servicing fees (up $0.2 million or 34% on the larger
35

portfolio serviced for others), partially offset by $0.8 million MSR asset impairment given faster paydown activity. See also “Lending-Related Commitments” and Note 7, “Goodwill and Other Intangibles and Mortgage Servicing Rights” of the Notes to Unaudited Consolidated Financial Statements under Part I, Item 1, for additional disclosures on the MSR asset.
Service charges on deposit accounts were down $0.5 million to $3.1 million for the nine months ended September 30, 2020, mainly as we waived certain fees during second quarter 2020 to provide economic relief to our customers.
Card interchange income grew $0.3 million (5%) due to higher volume and activity, especially seen in third quarter 2020, as the first half activity was tempered by cautionary spending of consumers given the economic uncertainty.
BOLI income was down $0.1 million between the comparable nine-month periods, attributable to the difference in BOLI death benefits received in each nine-month period (down $0.2 million), partly offset by income on higher average balances from $5 million additional BOLI purchased in mid-2019, $6 million BOLI acquired with Choice, and $3 million BOLI acquired with Advantage.
Other income of $3.2 million for the nine months ended September 30, 2020 was down $1.0 million from the comparable 2019 period, largely due to $0.5 million lower income from our smaller equity interest in a data processing entity after the partial sale in May 2019 and $0.3 million attributable to the fee earned on a customer loan interest rate swap in second quarter 2019.
Net asset losses of $1.2 million in the first nine months of 2020 were primarily attributable to unfavorable fair value marks on equity securities and the $0.1 million write-off of Commerce common stock in connection with the terms of the mutual termination of the Commerce merger agreement, partly offset by gains of $0.3 million on the sale of securities AFS. Net asset gains of $8.0 million in the first nine months of 2019 were comprised primarily of the $7.4 million gain on the equity investment sale and $0.9 million of favorable fair value marks on equity securities, partially offset by losses of $0.3 million on fixed asset disposals and write-downs of OREO and other investments.

Noninterest expense was $75.4 million, an increase of $4.0 million (6%) over the first nine months of 2019, largely due to the expanded operating base following the Choice and Advantage acquisitions, as well as one-time expenses in second quarter 2020 associated with the announced branch closures, safety efforts related to the pandemic, a micro-grant program and a merger termination charge (collectively $4.0 million), while second quarter 2019 included $2.75 million of nonrecurring retirement-related compensation declared. Personnel costs increased $1.1 million (3%), while non-personnel expenses combined increased $2.9 million (10%) over the first nine months of 2019.
Personnel expense was $41.9 million for the nine months ended September 30, 2020, an increase of $1.1 million from the comparable period in 2019. Excluding the $2.75 million nonrecurring compensation from the 2019 period, personnel expense increased $3.8 million (10%). The increase is mainly due to strong merit increases between the periods (increasing salary expense and 401k expense), higher stock-based compensation, as well as higher health and other fringes. While average FTEs were minimally changed between the year-to-date periods, the three-quarter trend was increasing for 2019 and decreasing for 2020 with the additional headcount from the Choice and Advantage acquisitions, largely offset by reductions from the branch closures. Personnel expense was also impacted by $0.4 million higher overtime to process mortgage and PPP volume, $0.2 million severance related to the branch closures, and $0.4 million of on-site bonus pay.
Occupancy, equipment and office expense was $12.6 million for the first nine months of 2020, up $1.7 million (15%) compared to the first nine months of 2019, with 2020 including $0.5 million of accelerated depreciation and write-offs related to the
36

branch closures, higher expense for software and technology to drive operational efficiency and enhance products or services, and for additional licensing and equipment to expand remote workers in response to the COVID-19 pandemic. The comparable nine-month period of 2019 also included approximately $0.2 million of accelerated depreciation for branch facility upgrades.
Business development and marketing expense was $4.7 million, up $0.4 million or 9%, between the comparable nine-month periods, largely due to $1.25 million for the micro-grant program, partly offset by lower business development costs from less travel and entertainment during the pandemic.
Data processing expense was $7.6 million, up $0.4 million or 6% between the comparable nine-month periods, mostly due to volume-based increases in core processing charges.
Intangibles amortization decreased $0.2 million between the comparable nine-month periods mainly from declining amortization on the aging intangibles of previous acquisitions, partly offset by amortization from the new intangibles of the August 2020 Advantage and November 2019 Choice acquisitions.
Other expense was $5.8 million, up $0.7 million (13%) between the comparable nine-month periods. The first nine months of 2020 included $1.0 million of lease termination charges related to the branch closures, $0.5 million to terminate the Commerce merger agreement and a $0.3 million charge on the early repayment of FHLB advances, while the first nine months of 2019 included $0.2 million higher FDIC insurance costs and a $0.6 million fraud loss contingency.
Income Taxes
Income tax expense was $14.3 million (effective tax rate of 25.27%) for the first nine months of 2020, compared to $10.8 million (effective tax rate of 20.20%) for the comparable period of 2019. The lower effective tax rate for 2019 was due to the favorable tax treatment of the equity investment sale, BOLI death benefit proceeds, and higher tax benefit on stock-based compensation.

Income Statement Analysis – Three Months Ended September 30, 2020 versus Three Months Ended September 30, 2019
Net income was $18.1 million for the three months ended September 30, 2020, an increase of $4.6 million (34%) from $13.5 million for the three months ended September 30, 2019. Earnings per diluted common share was $1.72 for third quarter 2020, compared to $1.40 for third quarter 2019.
Tax-equivalent net interest income was $32.8 million for third quarter 2020, comprised of net interest income of $32.6 million ($3.4 million or 12% over third quarter 2019), and a tax-equivalent adjustment of $0.2 million (down minimally from third quarter 2019). Tax-equivalent interest income increased $2.6 million between the third quarter periods, with $9.6 million from stronger volumes (led by average loans which grew $653 million or 29% over third quarter 2019, mostly from the PPP loans and the loans acquired with Choice and Advantage, as well as significantly higher cash included in other interest earning assets, up $702 million to represent 20% of interest-earning assets for third quarter 2020 compared to 5% for third quarter 2019), partly offset by $7.0 million from lower yields across most interest-earning assets given the Federal Reserve interest rate cuts in second half 2019 and March 2020. Interest expense decreased $0.8 million from third quarter 2019, as the impact of the lower interest rate environment more than offset the higher average deposit and funding balances. For additional information regarding average balances, net interest income and net interest margin, see “Income Statement Analysis — Net Interest Income.”
The net interest margin for third quarter 2020 was 3.06%, down from 4.19% for third quarter 2019, heavily influenced by the changing balance sheet mix, especially to low-earning cash. The yield on interest-earning assets of 3.50% declined 147 bps from third quarter 2019 (mostly due to the dramatic increase in cash that generally earns 10 bps since March 2020, as well as the low rate on the PPP loans). The yield on loans excluding PPP loans was 4.89%, 67 bps lower than third quarter 2019 mostly attributable to the impact of the lower interest rate environment on variable loans offset partly by floors and the mix of fixed rate loans. The cost of funds of 0.64% declined 50 bps between the comparable quarters as both deposit and other funding costs were adjusted down in the lower interest rate environment, as well as the inclusion of PPPLF funds costing 35 bps.
Provision for credit losses in third quarter 2020 was $3.0 million, compared to provision for credit losses of $0.4 million for third quarter 2019 given the vastly different economic conditions between the third quarter periods and the unknown magnitude of the evolving impact of current credit stress on our customers arising from pandemic-based business disruptions and other recessionary conditions. Net charge-offs were 0.10% and 0.06%, for third quarter 2020 and 2019, respectively.
Noninterest income was $18.7 million for third quarter 2020, an increase of $6.4 million (52%) from third quarter 2019, driven by strong secondary mortgage income. Net mortgage income of $9.7 million for third quarter 2020 was up $6.0 million (161%) over third quarter 2019 from higher sale gains and capitalized gains combined (up $6.2 million or 163%, commensurate with the increase in volumes sold into the secondary market, aided by the current refinance boom, and better pricing between the years), a larger servicing portfolio, and a $0.1 million favorable change in the fair value of the mortgage derivatives, partially offset by $0.4 million MSR asset impairment given higher refinance activity. Trust services fee income and brokerage fee

income combined was up $0.4 million (11%), consistent with the growth in assets under management. Service charges on deposit accounts were down $0.2 million to $1.0 million for third quarter 2020, mainly on lower NSF charges. Card interchange income grew $0.1 million (8%) due to higher volume and activity. For additional information regarding noninterest income, see “Income Statement Analysis — Noninterest Income.”
Noninterest expense was $23.7 million for third quarter 2020, an increase of $0.8 million (3%) from third quarter 2019, including a $1.2 million increase in personnel expense partly offset by a $0.4 million decrease in non-personnel expenses. Personnel expense increased $1.2 million (9%), mainly due to strong merit increases between the periods (increasing salary expense and stock-based compensation), as well as higher health and other fringes. Average FTEs were down 8% between the comparable quarters as the timing of the additional headcount from the Choice and Advantage acquisitions, was more than offset by reductions from the branch closures. Occupancy, equipment, and office of $4.1 million was up $0.6 million (17%), attributable to the larger operating base and higher expense for software and technology to drive operational efficiency, enhance products or services, and support the expanded remote worker capabilities. Business development and marketing of $0.8 million decreased $0.6 million (43%) versus third quarter 2019 as travel, educational and entertainment costs were dramatically reduced during the pandemic. All remaining noninterest expense categories on a combined basis were down $0.3 million (7%) as third quarter 2019 included $0.2 million for a fraud loss contingency matter. For additional information regarding noninterest expense, see “Income Statement Analysis — Noninterest Expense.”
Income tax expense for third quarter 2020 was $6.4 million, with an effective tax rate of 26.19%, compared to income tax expense of $4.6 million and an effective tax rate of 25.27% for third quarter 2019.

BALANCE SHEET ANALYSIS
At September 30, 2020, assets were $4.7 billion, an increase of $1.1 billion (32%) from December 31, 2019. The increase from year-end 2019 was largely due to higher cash and cash equivalents (up $672 million to $854 million, commensurate with the increase in total deposits) and loans. Period end loans of $2.9 billion at September 30, 2020, increased $335 million from December 31, 2019, with the net carrying value of PPP loans adding $335 million and Advantage adding $88 million at acquisition, net of a decline in the remaining loan portfolio (led by commercial lines of credit). Total deposits were $3.7 billion at September 30, 2020, an increase of a $758 million from year-end 2019, with customer deposits (core) up $592 million and brokered deposits up $167 million, influenced by liquidity objectives of customers and the Bank in the very uncertain times. Borrowings increased $338 million mostly due to participation in the PPPLF to fund the PPP loans. Total stockholders’ equity was $538 million, an increase of $22 million from December 31, 2019, primarily from earnings and positive net fair value investment changes, exceeding stock repurchases and the adoption of CECL, which negatively impacted equity by $6 million. See also Notes 1, “Basis of Presentation” and 6, “Loans, Allowance for Credit Losses - Loans, and Credit Quality” of the Notes to Unaudited Consolidated Financial Statements under Part I, Item 1, for additional information on the adoption of CECL.
Compared to September 30, 2019, assets were $4.7 billion, up $1.6 billion or 52%. Loans increased $666 million (30%) and deposits increased $1.1 billion (44%) over September 30, 2019, attributable to the increases from year-end 2019 noted above, as well as the acquisition of Choice in November 2019, which added $457 million in assets, $348 million in loans and $289 million of deposits at acquisition. Stockholders’ equity increased $110 million from September 30, 2019, primarily due to common stock issued in the November 2019 Choice acquisition of $80 million, as well as net income and positive net fair value investment changes, partially offset by stock repurchases over the year.

Loans
In addition to the discussion that follows, see also Note 1, “Basis of Presentation” and Note 6, “Loans, Allowance for Credit Losses - Loans, and Credit Quality,” in the Notes to Unaudited Consolidated Financial Statements under Part I, Item 1, for additional disclosures and accounting policy on loans.

Nicolet services a diverse customer base throughout northeastern and central Wisconsin and in Menominee, Michigan. The Company concentrates on originating loans in its local markets and assisting its current loan customers. The loan portfolio is widely diversified by types of borrowers, industry groups, and market areas. Significant loan concentrations are considered to exist for a financial institution when there are amounts loaned to multiple numbers of borrowers engaged in similar activities that would cause them to be similarly impacted by economic or other conditions. At September 30, 2020, no significant industry concentrations existed in Nicolet’s portfolio in excess of 10% of total loans.
38

With the emergence of the COVID-19 pandemic and the significance of stay-at-home orders in March 2020, Nicolet began proactive discussions and/or temporary loan modifications (such as interest-only or payment deferrals) before the CARES Act passed in late March. Such modifications are further discussed under “BALANCE SHEET ANALYSIS – Nonperforming Assets.” In addition, Nicolet evaluated its collective concentration in restaurants, retail, arts, recreation, tourism and other hospitality businesses, which represented approximately 15% of its loan portfolio at the start of the pandemic in March 2020, and has declined modestly since that time. It remains unknown yet how much the Paycheck Protection Program may alleviate potential loss concerns across business operators in Nicolet’s loan portfolio who participated in the PPP. Further, it is unknown how businesses (individual customers or industry groups) will react or survive given the prolonged and evolving impact of the pandemic. These factors were part of the determination for a larger 2020 provision, and continue to be evaluated.
An active credit risk management process is used to ensure that sound and consistent credit decisions are made. The credit management process is regularly reviewed and the process has been modified over the past several years to further strengthen the controls. Factors that are important to managing overall credit quality are sound loan underwriting and administration, systematic monitoring of existing loans and commitments, effective loan review on an ongoing basis, early problem loan identification and remedial action to minimize losses, an appropriate ACL-Loans, and sound nonaccrual and charge-off policies.

Broadly, the loan portfolio at September 30, 2020, was 78% commercial-based and 22% retail-based. Commercial-based loans are considered to have more inherent risk of default than retail-based loans, in part because of the broader list of factors that could impact a commercial borrower negatively. In addition, the commercial balance per borrower is typically larger than that for retail-based loans, implying higher potential losses on an individual customer basis. Credit risk on commercial-based loans is largely influenced by general economic conditions and the resulting impact on a borrower’s operations or on the value of underlying collateral, if any. PPP loans, however, initially added during second quarter 2020, are fully guaranteed by the SBA, warranting no credit loss provisions.
Commercial-based loans of $2.3 billion increased $344 million (18%) since December 31, 2019, primarily due to the $335 million net carrying value added with the PPP loans and the $88 million of loans added with Advantage at acquisition, partly offset by declines in the remaining commercial-based loans (mostly commercial lines of credit), as many commercial customers funded their current needs through the PPP loans and exercised caution in this volatile and uncertain business climate. Commercial and industrial loans continue to be the largest segment of Nicolet’s portfolio and represented 25% of the total portfolio at September 30, 2020.
Residential real estate loans of $598 million were down $12 million (2%) from year-end 2019, to represent 21% of total loans at September 30, 2020. Residential first mortgage loans include conventional first-lien home mortgages, while residential junior mortgage real estate loans consist mainly of home equity lines and term loans secured by junior mortgage liens. As part of its management of originating residential mortgage loans, the vast majority of Nicolet’s long-term, fixed-rate residential real estate mortgage loans are sold in the secondary market with servicing rights retained. Nicolet’s mortgage loans are typically of high quality and have historically had low net charge-off rates.
39

Retail and other loans were relatively unchanged from year-end 2019, and represented approximately 1% of the total loan portfolio, and include predominantly short-term and other personal installment loans not secured by real estate.

Allowance for Credit Losses - Loans
In addition to the discussion that follows, see also Note 1, “Basis of Presentation” and Note 6, “Loans, Allowance for Credit Losses - Loans, and Credit Quality,” in the Notes to Unaudited Consolidated Financial Statements under Part I, Item 1, for additional disclosures and accounting policy on the allowance for credit losses.
Credit risks within the loan portfolio are inherently different for each loan type as summarized under “BALANCE SHEET ANALYSIS — Loans.” A discussion of the loan portfolio credit risk can be found in the “Loans” section in Management's Discussion and Analysis of Financial Condition and Results of Operations included in the Company's 2019 Annual Report on Form 10-K. Credit risk is controlled and monitored through the use of lending standards, a thorough review of potential borrowers, and ongoing review of loan payment performance. Active asset quality administration, including early problem loan identification and timely resolution of problems, aids in the management of credit risk and minimization of loan losses. For additional information regarding nonperforming assets see also “BALANCE SHEET ANALYSIS – Nonperforming Assets.”
The ACL-Loans represents management’s estimate of expected credit losses in the Company’s loan portfolio at the balance sheet date. To assess the appropriateness of the ACL-Loans, an allocation methodology is applied by Nicolet which focuses on evaluation of qualitative and environmental factors, including but not limited to: (i) evaluation of facts and issues related to specific loans; (ii) management’s ongoing review and grading of the loan portfolio; (iii) consideration of historical loan loss and delinquency experience on each portfolio segment; (iv) trends in past due and nonperforming loans; (v) the risk characteristics of the various loan segments; (vi) changes in the size and character of the loan portfolio; (vii) concentrations of loans to specific borrowers or industries; (viii) existing economic conditions; (ix) the fair value of underlying collateral; and (x) other qualitative and quantitative factors which could affect expected credit losses. Assessing these numerous factors involves significant judgment; therefore, management considers the ACL-Loans a critical accounting policy.
Management allocates the ACL-Loans by pools of risk within each loan portfolio segment. The allocation methodology consists of the following components. First, a specific reserve is established for individually evaluated credit-deteriorated loans, which management defines as nonaccrual credit relationships over $250,000, collateral dependent loans, and other loans with evidence of credit deterioration. The specific reserve in the ACL-Loans for these credit deteriorated loans is equal to the aggregate collateral or discounted cash flow shortfall. Management allocates the ACL-Loans with historical loss rates by loan segment. The loss factors are measured on a quarterly basis and applied to each loan segment based on current loan balances and projected for their expected remaining life. Next, management allocates ACL-Loans using the qualitative factors mentioned above. Consideration is given to those current qualitative or environmental factors that are likely to cause estimated credit losses as of the evaluation date to differ from the historical loss experience of each loan segment. Lastly, management considers reasonable and supportable forecasts to assess the collectability of future cash flows.
At September 30, 2020, the ACL-Loans was $31.4 million (representing 1.08% of period end loans and 1.22% of period end loans excluding PPP loans) compared to $14.0 million at December 31, 2019 and $13.6 million at September 30, 2019. The increase in the ACL-Loans was largely due to the $9.3 million impact from the adoption of CECL (comprised of $8.5 million for the CECL impact on the loan portfolio and $0.8 million for the PCD gross-up) and a much higher provision for credit losses in 2020 given the unprecedented economic disruptions and uncertainty surrounding the COVID-19 pandemic. The components of the ACL-Loans are detailed further in Table 7 below.

Nonperforming Assets
As part of its overall credit risk management process, management is committed to an aggressive problem loan identification philosophy. This philosophy has been implemented through the ongoing monitoring and review of all pools of risk in the loan portfolio to ensure that problem loans are identified early and the risk of loss is minimized. Management is actively working with customers and monitoring credit risk from the unprecedented economic disruptions surrounding the COVID-19 pandemic as described in further detail in the “Overview” section. Since the pandemic started, approximately 980 loans (88% commercial and 12% retail) were provided payment modifications, consistent with the guidelines of the CARES Act, on loans totaling $462 million (65% interest only and 35% full payment deferrals). As of September 30, 2020, $384 million (83%) had returned to normal payment structures and $19 million (4%) were paid off or removed (of which one was a September charge-off for $0.5 million). The remaining $60 million (in 66 commercial and 6 retail loans) remained under modification structure, representing only 2% of September period end loans excluding PPP loans, and we expect approximately $45 million of these to end their modification periods by November. See also Note 6, “Loans, Allowance for Credit Losses - Loans, and Credit Quality” of the Notes to Unaudited Consolidated Financial Statements under Part I, Item 1, for additional disclosures on credit quality. For additional information see also “BALANCE SHEET ANALYSIS – Loans” and “BALANCE SHEET ANALYSIS – Allowance for Credit Losses-Loans.”
Nonperforming loans are considered one indicator of potential future loan losses. Nonperforming loans are defined as nonaccrual loans and loans 90 days or more past due but still accruing interest. Loans are generally placed on nonaccrual status when contractually past due 90 days or more as to interest or principal payments. Additionally, whenever management becomes aware of facts or circumstances that may adversely impact the collectability of principal or interest on loans, it is management’s practice to place such loans on nonaccrual status immediately. Nonaccrual loans decreased to $11 million at September 30, 2020, compared to $14 million at December 31, 2019, largely due to pay downs on a few larger commercial credits and an $0.8 million charge-off on one commercial credit relationship. Nonperforming assets (which include nonperforming loans and other real estate owned “OREO”) were $12 million at September 30, 2020 compared to $15 million at December 31, 2019. OREO was $1 million at both September 30, 2020 and December 31, 2019.
41

The level of potential problem loans is another predominant factor in determining the relative level of risk in the loan portfolio and in determining the appropriate level of the ACL-Loans. Potential problem loans are generally defined by management to include loans rated as Substandard by management but that are in performing status; however, there are circumstances present which might adversely affect the ability of the borrower to comply with present repayment terms. The decision of management to include performing loans in potential problem loans does not necessarily mean that Nicolet expects losses to occur, but that management recognizes a higher degree of risk associated with these loans. The loans that have been reported as potential problem loans are predominantly commercial-based loans covering a diverse range of businesses and real estate property types. Potential problem loans were $27 million (0.9% of loans) and $23 million (0.9% of loans) at September 30, 2020 and December 31, 2019, respectively. Potential problem loans require a heightened management review of the pace at which a credit may deteriorate, the duration of asset quality stress, and uncertainty around the magnitude and scope of economic stress that may be felt by Nicolet’s customers and on underlying real estate values.

Deposits
Deposits represent Nicolet’s largest source of funds. The deposit composition is presented in Table 9 below.
Total deposits of $3.7 billion at September 30, 2020, increased $758 million (26%) over December 31, 2019, and was a large contributor to the current heavy cash position. This unusually large increase in deposits was influenced by the very uncertain times, government stimulus payments and pandemic stay-at-home orders, which reduced spending and increased liquidity of consumers and businesses, and by PPP loan proceeds retained on deposit by corporate borrowers. Also contributing to the increase in deposits from December 31, 2019, was the acquisition of Advantage, which added $141 million of deposits at acquisition. Noninterest-bearing demand deposits accounted for the largest increase since December 31, 2019, up $316 million (39%), primarily due to the deposited PPP loan proceeds. Transaction accounts combined (i.e., savings, money market, and interest-bearing demand) increased $341 million (22%) to $1.9 billion at September 30, 2020, and brokered deposits grew $167 million (104%) to $327 million, mainly due to our liquidity build executed in March-April offset partly by maturities of
42

acquired brokered deposits, while core time deposits declined $66 million (15%) to $373 million, largely moving into transaction accounts.
Compared to September 30, 2019, total deposits were up $1.1 billion (44%). The increase in total deposits since September 30, 2019 was largely due to the liquidity objectives of customers and the Bank in very uncertain times, and the acquisition of Advantage (as discussed above), as well as the acquisition of Choice, which added $289 million of deposits at acquisition.

Lending-Related Commitments
As of September 30, 2020 and December 31, 2019, Nicolet had the following off-balance sheet lending-related commitments.

Interest rate lock commitments to originate residential mortgage loans held for sale (included above in commitments to extend credit) and forward commitments to sell residential mortgage loans held for sale are considered derivative instruments (“mortgage derivatives”) and represented $132 million and $78 million, respectively, at September 30, 2020. In comparison, interest rate lock commitments to originate residential mortgage loans held for sale and forward commitments to sell residential mortgage loans held for sale represented $43 million and $16 million, respectively, at December 31, 2019. The net fair value of these mortgage derivatives combined was a loss of $186,000 at September 30, 2020 compared to a gain of $79,000 at December 31, 2019.

Liquidity Management
Liquidity management refers to the ability to ensure that cash is available in a timely and cost-effective manner to meet cash flow requirements of depositors and borrowers and to meet other commitments as they fall due, including the ability to service debt, invest in subsidiaries, repurchase common stock, pay dividends to shareholders (if any), and satisfy other operating requirements.
Given the stable core customer deposit base, fairly consistent patterns of activity in the core deposit base (including extra growth in core deposits during the pandemic as previously discussed), and the minimal use of capacity available in numerous non-core funding sources, Nicolet's liquidity levels and resources have been sufficient to fund loans, accommodate deposit trends and cycles, and to meet other cash needs as necessary. In early March-April 2020, in response to the emerging crisis, management initiated preparatory actions to further increase on-balance sheet liquidity, and brokered deposits of approximately $200 million were procured, increasing liquid cash. These actions were initiated prior to the passing of the CARES Act. In addition to the on-balance sheet liquidity build, remaining liquidity facilities continue to provide capacity and flexibility in an uncertain time.
Funds are available from a number of basic banking activity sources including, but not limited to, the core deposit base; repayment and maturity of loans; investment securities calls, maturities, and sales; and procurement of additional brokered deposits or other wholesale funding. All securities AFS and equity securities (included in other investments) are reported at fair
43

value on the consolidated balance sheet. At September 30, 2020, approximately 27% of the $535 million securities AFS portfolio was pledged to secure public deposits and short-term borrowings, as applicable, and for other purposes as required by law. Additional funding sources at September 30, 2020, consist of $175 million of available and unused Federal funds lines, available borrowing capacity at the FHLB of $160 million, and borrowing capacity in the brokered deposit market.
In consideration of the funds availability for the Bank and the current high levels of cash in a very low interest rate environment, management has taken prudent pricing actions on deposits and loans, as well as actions to reduce non-deposit funding. Brokered deposits have matured without renewal and selected FHLB advances were paid early. In addition, management intends to fully repay the PPPLF funding before the end of 2020, given ample levels of all other funding combined.
Management is committed to the parent Company being a source of strength to the Bank and its other subsidiaries, and therefore, regularly evaluates capital and liquidity positions of the parent Company in light of current and projected needs, growth or strategies. Dividends from the Bank and, to a lesser extent, stock option exercises, represent significant sources of cash flows for the parent Company. Among others, additional cash sources available to the parent Company include access to the public or private markets to issue new equity, subordinated debt or other debt. The parent Company uses cash for normal expenses, debt service requirements, and when opportune, for common stock repurchases, repayment of debt, or investment in other strategic actions such as mergers or acquisitions. Based on this evaluation, the Company is in the process of the early redemption of its higher-costing fixed rate subordinated Notes ($12 million at 5%) and one issuance of fixed rate junior subordinated debentures ($6 million at 8%), expected to be completed before the end of 2020. At September 30, 2020, the parent Company had $49 million in cash.
Cash and cash equivalents at September 30, 2020 and December 31, 2019 were $854 million and $182 million, respectively. The increase in cash and cash equivalents since year-end 2019 was largely attributable to the significant increase in deposits, influenced by government stimulus payments and the evolving pandemic crisis, which reduced spending and increased liquidity of consumers and businesses in these uncertain times, and PPP loan proceeds retained on deposit by corporate borrowers, as well as our own liquidity actions in March-April. Management believes its liquidity resources were sufficient as of September 30, 2020 to fund loans, accommodate deposit cycles and trends, and to meet other cash needs as necessary in these unsettled times.

Interest Rate Sensitivity Management and Impact of Inflation
A reasonable balance between interest rate risk, credit risk, liquidity risk and maintenance of yield, is highly important to Nicolet’s business success and profitability. As an ongoing part of its financial strategy and risk management, Nicolet attempts to understand and manage the impact of fluctuations in market interest rates on its net interest income. The consolidated balance sheet consists mainly of interest-earning assets (loans, investments and cash) which are primarily funded by interest-bearing liabilities (deposits and other borrowings). Such financial instruments have varying levels of sensitivity to changes in market rates of interest. Market rates are highly sensitive to many factors beyond our control, including but not limited to general economic conditions and policies of governmental and regulatory authorities. Our operating income and net income depends, to a substantial extent, on “rate spread” (i.e., the difference between the income earned on loans, investments and other earning assets and the interest expense paid to obtain deposits and other funding liabilities).
Asset-liability management policies establish guidelines for acceptable limits on the sensitivity to changes in interest rates on earnings and market value of assets and liabilities. Such policies are set and monitored by management and the board of directors’ Asset and Liability Committee.
To understand and manage the impact of fluctuations in market interest rates on net interest income, Nicolet measures its overall interest rate sensitivity through a net interest income analysis, which calculates the change in net interest income in the event of hypothetical changes in interest rates under different scenarios versus a baseline scenario. Such scenarios can involve static balance sheets, balance sheets with projected growth, parallel (or non-parallel) yield curve slope changes, immediate or gradual changes in market interest rates, and one-year or longer time horizons. The simulation modeling uses assumptions involving market spreads, prepayments of rate-sensitive instruments, renewal rates on maturing or new loans, deposit retention rates, and other assumptions.
Among other scenarios, Nicolet assessed the impact on net interest income in the event of a gradual +/-100 bps and +/-200 bps change in market rates (parallel to the change in prime rate) over a one-year time horizon to a static (flat) balance sheet. The results provided include the liquidity measures mentioned earlier and reflect the changed interest rate environment in response to the current crisis. The interest rate scenarios are used for analytical purposes only and do not necessarily represent management’s view of future market interest rate movements. Based on financial data at September 30, 2020 and December 31, 2019, the projected changes in net interest income over a one-year time horizon, versus the baseline, are presented in Table 11 below. The results are within Nicolet’s guidelines of not greater than -10% for +/- 100 bps and not greater than -15% for +/- 200 bps and given the relatively short nature of the Company's balance sheet, reflect a largely unchanged risk position as expected.

100 bps decrease in interest rates(0.2)%(1.0)%
100 bps increase in interest rates2.1 %0.8 %
200 bps increase in interest rates4.1 %1.7 %
Actual results may differ from these simulated results due to timing, magnitude and frequency of interest rate changes, as well as changes in market conditions and their impact on customer behavior and management strategies.
The effect of inflation on a financial institution differs significantly from the effect on an industrial company. While a financial institution’s operating expenses, particularly salary and employee benefits, are affected by general inflation, the asset and liability structure of a financial institution consists largely of monetary items. Monetary items, such as cash, investments, loans, deposits and other borrowings, are those assets and liabilities which are or will be converted into a fixed number of dollars regardless of changes in prices. As a result, changes in interest rates have a more significant impact on a financial institution’s performance than does general inflation.

Capital
Management regularly reviews the adequacy of its capital to ensure that sufficient capital is available for current and future needs and is in compliance with regulatory guidelines and actively reviews capital strategies in light of perceived business risks associated with current and prospective earning levels, liquidity, asset quality, economic conditions in the markets served, and level of returns available to shareholders. Management intends to maintain an optimal capital and leverage mix for growth and shareholder return. For details on the change in capital see “BALANCE SHEET ANALYSIS.”
The Company’s and the Bank’s regulatory capital ratios remain above minimum regulatory ratios, including the capital conservation buffer. At September 30, 2020, the Bank’s regulatory capital ratios qualify the Bank as well-capitalized under the prompt-corrective action framework. This strong base of capital has allowed Nicolet to be opportunistic in the current environment and in strategic growth. A summary of Nicolet’s and the Bank’s regulatory capital amounts and ratios, as well as selected capital metrics are presented in the following table.

In managing capital for optimal return, we evaluate capital sources and uses, pricing and availability of our stock in the market, and alternative uses of capital (such as the level of organic growth or acquisition opportunities) in light of strategic plans. Based on this evaluation, the Company is in the process of the early redemption of certain capital-equivalent debt, including its
45

higher-costing fixed rate subordinated Notes ($12 million at 5%) and its fixed rate junior subordinated debentures ($6 million at 8%), expected to be completed before the end of 2020. These early redemptions are expected to reduce the Company's Tier 1 risk-based capital by $6 million and Total risk-based capital by $16 million. The redemptions will have no impact on the Bank's risk-based capital.
The Company resumed its share repurchase program in late July given current conditions, market opportunities and financial performance of the Company. On August 18, 2020, Nicolet's board authorized an increase to the program of $20 million or up to 325,000 shares of common stock. As a result, at September 30, 2020, there remained $13.4 million authorized under this repurchase program, as modified, to be utilized from time-to-time to repurchase shares in the open market, through block transactions or in private transactions.

Critical Accounting Policies
In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheet and revenues and expenses for the period. Actual results could differ significantly from those estimates. Estimates that are particularly susceptible to significant change include the valuation of loan acquisition transactions, as well as the determination of the allowance for credit losses and income taxes. A discussion of these policies can be found in the “Critical Accounting Policies” section in Management’s Discussion and Analysis of Financial Condition and Results of Operations included in the Company’s 2019 Annual Report on Form 10-K. There have been no changes in the Company’s determination of critical accounting policies since December 31, 2019. See also Note 1, “Basis of Presentation” of the Notes to Unaudited Consolidated Financial Statements under Part I, Item 1, for changes to the Company's accounting policies on loans and the allowance for credit losses due to the adoption of CECL.

Future Accounting Pronouncements
Recent accounting pronouncements adopted are included in Note 1, “Basis of Presentation” of the Notes to Unaudited Consolidated Financial Statements within Part I, Item 1.
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. This ASU provides optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. It provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The updated guidance is effective for all entities as of March 12, 2020 through December 31, 2022. The Company continues to evaluate the impact of reference rate reform on its consolidated financial statements.

PART II – OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS
We and our subsidiaries may be involved from time to time in various routine legal proceedings incidental to our respective businesses. Neither we nor any of our subsidiaries are currently engaged in any legal proceedings that are expected to have a material adverse effect on our results of operations or financial position.

ITEM 1A. RISK FACTORS
There have been no material changes in the risk factors previously disclosed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019, except as disclosed below.
The recent global coronavirus outbreak could harm business and results of operations for Nicolet.
In December 2019, a coronavirus (COVID-19) was reported in China, and has since spread to additional countries including the United States. In March 2020, the World Health Organization declared the coronavirus to be a pandemic. Given the ongoing and dynamic nature of the circumstances, it is difficult to predict the impact of the coronavirus pandemic on the businesses of Nicolet and on its customers, and there is no guarantee that efforts by Nicolet to address the adverse impacts of the coronavirus will be effective. The impact to date has included periods of significant volatility in financial, commodities and other markets. This volatility, if it continues, could have an adverse impact on Nicolet’s customers and on Nicolet’s business, financial condition and results of operations. Nicolet may also incur additional costs to remedy damages caused by business disruptions.
In addition, recent actions by U.S. federal, state and foreign governments to address the pandemic, including travel bans and school, business and entertainment venue closures, may also have a significant adverse effect on the markets in which Nicolet conducts its businesses. The extent of impacts resulting from the coronavirus pandemic and other events beyond the control of Nicolet will depend on future developments, which are highly uncertain and cannot be predicted, including new information which may emerge concerning the severity of the coronavirus pandemic and actions taken to contain the coronavirus or its impact, among others.
