Note 1—Basis of Present ation

These unaudited interim condensed consolidated financial statements include the accounts of Byline Bancorp, Inc., a Delaware corporation (the “Company,” “Byline,” “we,” “us,” “our”), a bank holding company whose principal activity is the ownership and management of its Illinois state chartered subsidiary bank, Byline Bank (the “Bank”), based in Chicago, Illinois.

These unaudited interim condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X as promulgated by the Securities and Exchange Commission (“SEC”). In preparing these financial statements, the Company has evaluated events and transactions subsequent to September 30, 2019 for potential recognition or disclosure. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation of the financial position and results of operations for the periods presented have been included. Certain information in footnote disclosures normally included in financial statements prepared in accordance with GAAP has been condensed or omitted pursuant to the rules and regulations of the SEC and the accounting standards for interim financial statements. These financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Consolidated Financial Statements for the years ended December 31, 2018, 2017, and 2016.

In accordance with the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 855, “Subsequent Events,” the Company’s management has evaluated subsequent events for potential recognition or disclosure through the date of the issuance of these consolidated financial statements.

The Company has one reportable segment. The Company’s chief operating decision maker evaluates the operations of the Company using consolidated information for purposes of allocating resources and assessing performance. Therefore, segments disclosures are not required.

No subsequent events were identified that would have required a change to the consolidated financial statements or disclosure in the notes to the consolidated financial statements.

Certain prior period amounts have been reclassified to conform to current period presentation. These reclassifications did not result in any changes to previously reported net income or stockholders’ equity.

Note 2—Accounting Pronouncements Recently Adopted or Issued

The following reflect recent accounting pronouncements that have been adopted or are pending adoption by the Company. As the Company qualifies as an emerging growth company and has elected the extended transition period for complying with new or revised accounting pronouncements, it is not subject to new or revised accounting standards applicable to public companies during the extended transition period. The accounting pronouncements pending adoption below reflect effective dates for the Company as an emerging growth company with the extended transition period.

Adopted Accounting Pronouncements

Revenue from Contracts with Customers In May 2014, FASB issued Accounting Standards Update (“ASU”) No. 2014-09, deferred by ASU No. 2015-14 and clarifying standards, Revenue from Contracts with Customers , which creates Topics 606 and 610 and supersedes Topic 605, Revenue Recognition . The core principle of Topic 606 is that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In April 2016, FASB issued ASU No. 2016-10, Identifying Performance Obligations and Licensing . The amendments in this ASU clarify the following two aspects of Topic 606: (1) identifying performance obligations and (2) licensing implementation guidance, while retaining the related principles for those areas. In May 2016, FASB issued ASU No. 2016-12, Narrow-Scope Improvements and Practical Expedients , amending ASC Topic 606, Revenue from Contracts with Customers . The amendments in this ASU affect only several narrow aspects of Topic 606. In November 2017, FASB issued ASU No. 2017-14, amending ASC Topic 606, Revenue from Contracts with Customers . The ASU amends the codification to incorporate additional previously issued guidance from the SEC. The SEC issued SAB 116 to bring existing SEC staff guidance into conformity with the FASB’s adoption of and amendments to ASC Topic 606.

In general, the new guidance requires companies to use more judgment and make more estimates than under current guidance, including identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. The new authoritative guidance was initially effective for reporting periods after January 1, 2017 but was deferred to January 1, 2018. Given our emerging growth status, the Company adopted this new guidance on January 1, 2019 using the full retrospective method, meaning the standard is applied to all periods presented in the financial statements with the cumulative effect of initially applying the standard recognized at the beginning of the earliest period presented.

The majority of the Company’s revenue streams, including interest and dividend income, servicing fees, and gains on sales of loans and investments, are outside the scope of Topic 606. Revenue streams reported as fees and service charges on deposits, ATM and interchange fees, and wealth management and trust income are within the scope of Topic 606. The Company applied the requirements of Topic 606 to the revenue streams that are within its scope. The adoption of Topic 606 did not result in any changes in the either timing or amount of recognized; there was no cumulative effect adjustment to opening retained earnings as no material changes were identified in the timing of revenue recognition. However, the presentation of certain costs associated with our ATM and debit card income were offset against ATM and interchange income. This change in presentation resulted in $396,000 and $1.1 million of expenses for the three and nine months ended September 30, 2019, respectively, being netted against ATM and interchange fees and reported in non-interest income instead of as other non-interest expense in non-interest expense. In addition, to conform to the current period presentation, $241,000 and $837,000 of related expenses for the three and nine months ended September 30, 2018, respectively, were reclassified from other non-interest expense in non-interest expense to being netted against ATM and interchange fees in non-interest income. The Company elected to apply the practical expedient and therefore does not disclose information about remaining performance obligations that have an original expected term of one year or less and allows the Company to expense costs related to obtaining a contract as incurred when the amortization period would have been one year or less.

The Company adopted ASU 2014-09 using the full retrospective approach. The following table presents the impact of adopting the new revenue standard on our Consolidated Statements of Operations for the periods presented (in thousands):

Fees and service charges on deposits:

Fees and service charges on deposits include transaction and non-transaction based deposit fees. Transaction based fees on deposit accounts are charged to deposit customers for specific services provided to the customer. These fees include such items as wire fees, official check fees, and overdraft fees. These are contracts specific to each individual transaction and do not extend beyond the individual transaction. The performance obligation is completed and the fees are recognized at the time the specific transactional service is provided to the customer. Non-transactional deposit fees are typically monthly account maintenance fees charged on deposit accounts. These are day-to-day contracts that can be cancelled by either party without notice. The performance obligation is satisfied and the fees are recognized on a monthly basis after the service period is completed.

ATM and interchange fees:

ATM fees represent fees earned when a foreign debit or ATM card is used in a Byline Bank ATM. These fees are assessed and paid at the time of each transaction as the performance obligation is satisfied, which is at the point in time that the transaction is performed and approved. Interchange fees represent fees earned when a debit card issued by the Bank is used to purchase goods or services at a merchant. The merchant's bank pays the Bank a default interchange rate set by MasterCard on a transaction by transaction basis. Interchange fees are assessed as the performance obligation is satisfied, which is at the point in time the card transaction is authorized. The performance obligation is satisfied and the fees are earned when the cost of the transaction is charged to the Bank cardholders’ card. Direct expenses associated with ATM and debit cards are recorded as a net reduction against the ATM and interchange income.

Wealth management and trust income:

Wealth management and trust income represents fees earned by the Bank for discretionary investment management, trust administration, fiduciary and/or custody services rendered. Fees vary and are based on a contract with the customer. Fee income is determined as a percentage of assets under management and is recognized over the period the underlying account is serviced. Although some trust appointments can last for generations, most contracts are generally cancellable at any time, with the customer subject to a pro-rated fee in the month of termination.

Recognition and Measurement of Financial Assets and Financial Liabilities In January 2016, FASB issued ASU No. 2016-01, Recognition and Measurement of Financial Assets and Financia l Liabilities . The amendments in this ASU require equity securities to be measured at fair value with changes in the fair value recognized through net income. The amendments allow equity investments that do not have readily determinable fair values to be r emeasured at fair value under certain circumstances and require enhanced disclosures about those investments. The amendments simplify the impairment assessment of equity investments without readily determinable fair values. The amendments also eliminate th e requirement to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet. The amendments require entities to adjust fair v alue disclosures for financial instruments to be reflected at an exit price. The amendments in this ASU require separate presentation in other comprehensive income of the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments. This amendment excludes from net income gains or losses that the entity may not re alize because those financial liabilities are not usually transferred or settled at their fair values before maturity. The amendments in this ASU require separate presentation of financial assets and financial liabilities by measurement category and form o f financial asset (that is, securities or loans and receivables) on the balance sheet or in the accompanying notes to the financial statements. The Company adopted the provisions of ASU No. 2016-01 as of January 1, 2019. The adoption of this ASU resulted i n the Company reclassifying $1.4 million from other comprehensive income to retained earnings, representing t he unrealized gain , net of tax, on available-for- sale for sale equity securities at the date of adoption. The provisions of ASU No. 2016-01 require a ny future changes in fair value of equity securities to be recorded in the Consolidated Statements of Operations which could result in additional volatility in non-interest income. At December 31, 2018, the Company held $6.6 million of available-for-sale equity investment securities , which were previously reported as available-for-sale securities, at fair value , and are now reported as equity and other securities, at fair value .

In addition, the adoption of this ASU resulted in changing how the Company estimates the fair value of portfolio loans and leases for disclosure purposes. Fair values are estimated first by stratifying the portfolios of loans and leases with similar financial characteristics. Loans and leases are segregated by type such as commercial real estate, residential mortgage, construction, land, and development, commercial and industrial, consumer and other. Each loan and lease category is further segmented into fixed- and adjustable-rate interest terms. An estimate of fair value is then calculated based on discounted cash flows using as a discount rate based on the current rate offered on similar products, plus an adjustment for liquidity to reflect the non-homogeneous nature of the loans and leases, as well as a quarterly loss rate based on historical losses to arrive at an estimated exit price fair value. Fair value for impaired loans and leases is also based on recent appraisals or estimated cash flows discounted using rates commensurate with risk associated with the estimated cash flows. Assumptions regarding credit risk, cash flows and discount rates are judgmentally determined using available market information and specific borrower information.

Derivatives and Hedging (Topic 815) In August 2017, FASB issued ASU No. 2017-12, Targeted Improvements to Accounting for Hedging Activities . The amendments in this ASU better align an entity’s risk management activities and financial reporting for hedging relationships through changes to both the designation and measurement guidance for qualifying hedging relationships and the presentation of hedge results. The Company adopted the provisions of ASU No. 2017-12 on January 1, 2019. Upon adoption, the Company elected to reclassify $94.8 million of securities held-to-maturity to securities available-for-sale, which did not impact on the Consolidated Statements of Operations.

Compensation—Stock Compensation (Topic 718) In May 2017, the FASB issued ASU 2017-09, Scope of Modification Accounting . The amendments in the ASU provide guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in Topic 718. An entity should account for the effects of a modification unless all of the following are met: (1) the fair value (or calculated value or intrinsic value, if such an alternative measurement method is used) of the modified award is the same as the fair value (or calculated value or intrinsic value, if such an alternative measurement method is used) of the original award immediately before the original award is modified. If the modification does not affect any of the inputs to the valuation technique that the entity uses to value the award, the entity is not required to estimate the value immediately before and after the modification. (2) the vesting conditions of the modified award are the same as the vesting conditions of the original award immediately before the original award is modified. (3) the classification of the modified award is an equity instrument or liability instrument is the same as the classification of the original award immediately before the original award is modified. The amendments are effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2017. Early adoption is permitted, including adoption in any interim period, for reporting periods for which financial statements have not yet been issued. The amendments should be applied prospectively to an award modified on or after the adoption date. Given our emerging growth status, the Company adopted the provisions of ASU No. 2017-09 on January 1, 2019, which did not have a material impact on the Company’s Consolidated Financial Statements.

Statement of Cash Flows (Topic 230) In August 2016, FASB issued ASU No. 2016-15, Classification of Certain Cash Receipts and Cash Payments . There is diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows under Topic 230 and other Topics. This ASU addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice. Those eight issues are (1) debt prepayment or debt extinguishment costs, (2) settlement of zero-coupon debt instruments or other debt instruments with coupon inte rest rates that are insignificant in relation to the effective interest rate of the borrowing, (3) contingent consideration payments made after a business combination, (4) proceeds from the settlement of insurance claims, (5) proceeds from the settlement o f corporate-owned life insurance policies, including bank-owned life insurance policies, (6) distributions received from equity method investees, (7) beneficial interests in securitization transactions, and (8) separately identifiable cash flows and applic ation of the predominance principle. Current GAAP either is unclear or does not include specific guidance on these eight cash flow classification issues. These amendments provide guidance for each of the eight issues, thereby reducing current and potential future diversity in practice. The amendments in this ASU are effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. Given the Compa ny ’s emerging growth company status , the new authoritative guidance will be effective for reporting periods after January 1, 2019. The Company adopted the provisions of ASU No. 2016-15 on January 1, 2019, which did not have a material impact on the Company’s Consolidated Financial Statements.

In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230), Restricted Cash . The ASU will require that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The amendments in this update apply to all entities that have restricted cash or restricted cash equivalents and are required to present a statement of cash flows under Topic 230. The amendment is effective for annual reporting periods beginning after December 15, 2017, and interim periods within those fiscal years. Given our emerging growth status, the Company adopted these amendments on January 1, 2019 in conjunction with ASU No. 2016-15, which did not have a material impact on the Company’s Consolidated Financial Statements.

Business Combinations (Topic 805) In January 2017, the FASB issued ASU No. 2017-01, Clarifying the Definition of a Business . The guidance clarifies the definition of a business to assist entities with evaluating whether transactions should be accounted for as acquisitions or disposals of assets or businesses. This guidance is effective for annual and interim periods beginning after December 15, 2017. Given our emerging growth status, the Company adopted the provisions of ASU No. 2017-01 on January 1, 2019, which did not have a material impact on the Company’s Consolidated Financial Statements.

Fair Value Measurement (Topic 820) In August 2018, FASB issued ASU No. 2018-13, Disclosure Framework — Changes to the Disclosure Requirements for Fair Value Measurement . The amendments in this ASU modify the disclosure requirements on fair value measurements in Topic 820. The amendments remove the disclosure requirements for the amount and reasons for transfers between Level 1 and Level 2 securities of the fair value hierarchy, the policy for timing of transfers between levels, and the valuation processes for Level 3 fair value measurement. The amendments modify the disclosure requirements as follows: for investments in certain entities that calculate net asset value, an entity is required to disclose the timing of liquidation of an investee’s assets and the date when restrictions from redemption might lapse only if the investee has communicated the timing to the entity or announced the timing publicly; and clarify that the measurement uncertainty disclosure is to communicate information about the uncertainty in measurement as of the reporting date. The amendments add the following disclosure requirements: the changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period; and the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. Early adoption is permitted. The Company early adopted these amendments in 2018, which did not have a material impact on the Company’s Consolidated Financial Statements.

Leases (Topic 842) In February 2016, FASB issued ASU No. 2016-02, Leases . The amendments in this ASU require lessees to recognize the following for all leases (with the exception of short-term) at the commencement date: a lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis; and a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. The amendments in this ASU leave lessor accounting largely unchanged, although certain targeted improvements were made to align lessor accounting with the lessee accounting model. This ASU simplifies the accounting for sale and leaseback transactions primarily because lessees must recognize lease assets and lease liabilities. The amendments in this ASU are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early application is permitted upon issuance. Lessees (for capital and operating leases) and lessors (for sales-type, direct financing, and operating leases) must apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The modified retrospective approach would not require any transition accounting for leases that expired before the earliest comparative period presented. Lessees and lessors may not apply a full retrospective transition approach. The Company is evaluating the new guidance and its impact on the Company’s Consolidated Statements of Operations and Consolidated Statements of Financial Condition. In October 2019, FASB voted to defer the effective date of this ASU for entities not classified as Public Business Entities (PBEs). Our status as an emerging growth company makes us eligible for this deferral. Assuming the Company remains an emerging growth company, the proposed guidance will be effective for reporting periods after December 15, 2020, and interim periods with fiscal years beginning after December 15, 2021. The Company expects an increase in assets and liabilities as a result of recognizing additional right-of-use assets and liabilities under lease contracts in which the Company is lessee. While the Company has not quantified the impact of this ASU on its direct financing lease portfolio, it does not expect a material change in its accounting for the initial direct costs related to these leases.

Financial Instruments—Credit Losses (Topic 326) In June 2016, FASB issued ASU No. 2016-13, Measurement of Credit Losses on Financial Instruments . Current GAAP requires an “incurred loss” methodology for recognizing credit losses that delays recognition until it is probable a loss has been incurred. The main objective of this ASU is to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. The amendments in this ASU replace the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The amendments in this ASU require a financial asset (or group of financial assets) measured at amortized cost basis to be presented at the net amount expected to be collected. The allowance for credit losses is a valuation account that is deducted from the amortized cost basis of the financial asset(s) to present the net carrying value at the amount expected to be collected on the financial asset. The measurement of expected credit losses will be based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. The amendments in this ASU broaden the information that an entity must consider in developing its expected credit loss estimate for assets measured either collectively or individually. The use of forecasted information incorporates more timely information in the estimate of expected credit loss, which will be more useful to users of the financial statements. In October 2019, FASB voted to defer the effective date of the ASU for entities not classified as PBEs. Once issued, the Company intends to exercise the extension applicable to emerging growth companies. The Company is in process of implementation and determining the impact that this ASU will have on the Company’s Consolidated Financial Statements.

Nonrefundable Fees and Other Costs (Subtopic 310-20) In March 2017, FASB issued ASU No. 2017-08, Receivables—Nonrefundable Fees and Other Costs. The amendments in the ASU shorten the amortization period for certain callable debt securities held at a premium at the earliest call date. Under current GAAP, the Company amortizes the premium as an adjustment of yield over the contractual life of the instrument. As a result, upon exercise of a call on a callable debt security held at a premium, the unamortized premium is charged to earnings. The ASU shortens the amortization period for certain callable debt securities held at a premium and requires the premium to be amortized to the earliest call date. However, the amendments do not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. The amendments are effective for annual periods beginning after December 15, 2019, and interim periods within annual periods beginning after December 15, 2020. Early adoption is permitted. The Company is required to apply the amendments on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. Assuming the Company remains an emerging growth company, the new authoritative guidance will be effective for reporting periods after January 1, 2020. The Company is currently evaluating the provisions of ASU No. 2017-08 to determine the potential impact the new standard will have on the Company’s Consolidated Financial Statements.

Note 3—Acquisition s

On April 30, 2019, the Company acquired all of the outstanding common stock of Oak Park River Forest Bankshares, Inc. (“Oak Park River Forest”) and its subsidiary pursuant to an Agreement and Plan of Merger, dated as of October 17, 2018 (the “OPRF Merger Agreement”). Oak Park River Forest operated one wholly owned subsidiary, Community Bank of Oak Park River Forest. Oak Park River Forest was merged with and into Byline. As a result of the merger, Oak Park River Forest’s subsidiary bank, Community Bank of Oak Park River Forest, was merged with and into Byline Bank, with Byline Bank as the surviving bank.

At the effective time of the merger (the “OPRF Effective Time”), each share of Oak Park River Forest’s common stock was converted into the right to receive: (1) 7.9321 shares of Byline’s common stock, and (2) an amount in cash equal to $6.2 million divided by the number of outstanding shares of Oak Park River Forest common stock as of the closing date, with cash paid in lieu of any fractional shares. The per share cash consideration was based on the total $6.2 million divided by the outstanding shares of Oak Park River Forest common stock, or $33.375 per outstanding share. Based on the closing price of the Company’s common stock of $20.02, as reported by the New York Stock Exchange, and 1,464,558 shares of common stock issued with respect to the outstanding shares of Oak Park River Forest common stock, the stock consideration was valued at $29.3 million. Options to acquire 35,870 shares of Oak Park River Forest common stock that were outstanding at the OPRF Effective Time were cancelled, at the option holders election, in exchange for a cash payment in accordance with the OPRF Merger agreement of $4.2 million, to be paid after the closing date. The value of the total merger consideration at closing was $35.5 million before issuance costs of $429,000.

The transaction resulted in goodwill of $17.5 million, which is nondeductible for tax purposes, as this acquisition was a nontaxable transaction. Goodwill represents the premium paid over the fair value of the net tangible and intangible assets acquired and reflects related synergies expected from the combined operations. The Company incurred Oak Park River Forest merger-related expenses, including acquisition advisory expenses, of $2.3 million for the nine months ended September 30, 2019. The Company incurred merger-related income of $135,000 for the three months ended September 30, 2019, resulting from a legal fee credit. Core system conversion expenses were $1.2 million $1.9 million related to the Oak Park River Forest acquisition for the three and nine months ended September 30, 2019, respectively. These expenses are reflected in non-interest expense on the Consolidated Statements of Operations.

The acquisition of Oak Park River Forest was accounted for using the acquisition method of accounting in accordance with ASC Topic 805. Assets acquired, liabilities assumed and consideration exchanged were recorded at their respective acquisition date fair values. Determining the fair value of assets and liabilities involves significant judgment regarding methods and assumptions used to calculate estimated fair values. Fair values are preliminary and subject to refinement for up to one year after the closing date of the acquisition as additional information regarding the closing date fair values become available.

On May 31, 2018, the Company acquired all common stock of First Evanston Bancorp, Inc. (“First Evanston”) and its subsidiaries pursuant to an Agreement and Plan of Merger, dated as of November 27, 2017 (the “Merger Agreement”). First Evanston operated two wholly owned subsidiaries, First Bank & Trust and First Evanston Bancorp Trust I. First Evanston was merged with and into Byline. As a result of the merger, First Evanston’s subsidiary bank, First Bank & Trust, was merged with and into Byline Bank, with Byline Bank as the surviving bank.

At the effective time of the merger (the “Effective Time”), each share of First Evanston’s common stock was converted into the right to receive: (1) 3.994 shares of Byline’s common stock, and (2) an amount in cash equal to $27.0 million divided by the number of outstanding shares of First Evanston common stock as of the closing date, with cash paid in lieu of any fractional shares. The per share cash consideration was based on the total $27.0 million divided by the outstanding shares of First Evanston common stock, or $16.136 per outstanding share. Based on the closing price of the Company’s common stock of $21.62, as reported by the New York Stock Exchange, and 6,682,850 shares of common stock issued with respect to the outstanding shares of First Evanston common stock, the stock consideration was valued at $144.5 million. Options to acquire 144,090 shares of First Evanston common stock that were outstanding at the Effective Time were converted into options to acquire 680,787 shares of Byline common stock, resulting in a consideration value of $7.6 million. The value of the total merger consideration at closing was $179.1 million before issuance costs of $852,000.

The Company did not classify securities as trading during the three or nine months ended September 30, 2019 or during 2018.

The Company adopted the provisions of ASU No. 2016-01 as of January 1, 2019. The adoption of this ASU resulted in the reclassification of available-for-sale equity securities, at fair value to a separate line item on the Company’s Consolidated Statements of Financial Condition, and the reclassification of $1.4 million from other comprehensive income to retained earnings, representing the net unrealized gain, net of tax, on available-for-sale for sale equity securities at the date of adoption. At December 31, 2018, the Company held $6.6 million of available-for-sale equity investment securities which were reported as available-for-sale securities, at fair value, and are now reported as equity and other securities, at fair value. Additionally, the Company adopted the provisions of ASU No. 2017-12 on January 1, 2019, and elected to reclassify $94.8 million of securities held-to-maturity to securities available-for-sale, which did not have an impact on the Consolidated Statements of Operations.

Certain securities have fair values less than amortized cost and, therefore, contain unrealized losses. T he Company evaluated the securities which had an unrealized loss for o ther than temporary impairment and determined all declines in value to be temporary. There were 74 securities available-for-sale with unrealized losses at September 30, 2019 . There were no securities held-to-maturity with unrealized losses at September 30, 2019 . The Company anticipates full recovery of amortized cost with respect to these securities by maturity, or sooner, in the event of a more favorable market interest rate environment. The Company does not intend to sell these securities and it is not more likely than not that the Company will be required to sell them before recovery of their amortized cost basis, which may be at maturity.

The proceeds from all sales of securities available-for-sale, and the associated gains and losses, for the three and nine months ended September 30, 2019 and 2018 are listed below:

Originated loans and leases represent originations excluding loans initially acquired in a business combination. However, once an acquired non-impaired loan reaches its maturity date, and is re-underwritten and renewed, it is internally classified as an originated loan. Acquired impaired loans are loans acquired from a business combination with evidence of credit quality deterioration and are accounted for under ASC Topic 310-30. Acquired non-impaired loans and leases represent loans and leases acquired from a business combination without more than insignificant evidence of credit quality deterioration and are accounted for under ASC Topic 310-20. Acquired leases and revolving loans having evidence of credit quality deterioration do not qualify to be accounted for as acquired impaired loans and are accounted for under ASC Topic 310-20. The following tables summarize the balances for each respective loan and lease category as of September 30, 2019 and December 31, 2018:

Loans serviced for others are not included in the Consolidated Statements of Financial Condition. The unpaid principal balances of these loans serviced for others as of September 30, 2019 and December 31, 2018 were as follows :

Loan servicing revenue totaled $2.7 and $2.6 million for the three months ended September 30, 2019 and 2018, respectively. Loan servicing revenue totaled $7.9 and $7.6 million for the nine months ended September 30, 2019 and 2018, respectively. Loan servicing asset revaluation, which represents the changes in fair value of servicing assets, resulted in downward valuations of $1.6 and $2.4 million for the three months ended September 30, 2019 and 2018, respectively. Loan servicing asset revaluation resulted in downward valuations of $4.1 and $6.4 million for the nine months ended September 30, 2019 and 2018, respectively.

The fair value of servicing rights is highly sensitive to changes in underlying assumptions. Changes in prepayment speed assumptions have the most significant impact on the fair value of servicing rights.

Generally, as interest rates rise on variable rate loans, loan prepayments increase due to an increase in refinance activity, which may result in a decrease in the fair value of servicing assets. Measurement of fair value is limited to the conditions existing and the assumptions used as of a particular point in time, and those assumptions may change over time. Refer to Note 16—Fair Value Measurement for further details.

Note 10—Income Taxes

The Company uses an estimated annual effective tax rate method in computing its interim tax provision. This effective tax rate is based on forecasted annual pre-tax income, permanent tax differences and statutory tax rates.

The effective tax rate for the nine months ended September 30, 2019 and 2018 was 27.7% and 24.4%, respectively. The Company recorded discrete income tax benefit of $64,000 and $362,000 related to the exercise of stock options and vesting of restricted shares for the nine months ended September 30, 2019 and 2018, respectively. The current effective tax rate reflects the passage of the Tax Cuts and Jobs Act (the “Tax Act”), which was enacted on December 22, 2017. Among other things, the Tax Act reduces the corporate federal income tax rate from 35% to 21%, effective January 1, 2018. Also on December 22, 2017, the SEC issued Staff Accounting Bulletin 118 (“SAB 118”), which provides guidance on accounting for the Tax Act’s impact. SAB 118 provides a measurement period, not to extend beyond one year from the date of enactment during which a company, acting in good faith, may complete the accounting for the impacts of the Tax Act. The Company recorded an additional discrete income tax benefit of $724,000 during the first quarter of 2018. This adjustment includes the impact of the federal income tax rate decrease due to the Tax Act (enacted on December 22, 2017) on our net deferred tax assets.

Net deferred tax assets decreased to $33.4 million at September 30, 2019 compared to $35.6 million at December 31, 2018 . The net decrease in the total net deferred tax assets recorded as of September 30, 2019 was a result of $4.9 million in net deferred tax assets added related to the acquisition of Oak Park River Forest, offset by a decrease in net deferred tax assets related to unrealized losses on available-for-sale securities and utilization of operating loss carryforwards during the period.

Note 11—Deposits

The composition of deposits was as follows as of September 30, 2019 and December 31, 2018:

	September 30,		December 31,
	2019		2018

At September 30, 2019, fixed-rate advances totaled $506.0 million with interest rates ranging from 2.04% to 2.08% and maturities ranging from October 2019 to December 2019. The Company’s advances from the FHLB are collateralized by residential real estate loans, commercial real estate loans, and securities. The Company’s required investment in FHLB stock is $4.50 for every $100 in advances. At September 30, 2019 and December 31, 2018 , the Bank has additional borrowing capacity from the FHLB of $1.4 billion and $1.3 billion, respectively, subject to the availability of proper collateral. The Bank’s maximum borrowing capacity is limited to 35% of total assets.

The Company hedges interest rates on borrowed funds using interest rate swaps through which the Company receives variable amounts and pays fixed amounts. Refer to Note 17—Derivative Instruments and Hedging Activities for additional information.

Note 13—Other Borrowings

The following is a summary of the Company’s other borrowings as of September 30, 2019 and December 31, 2018:

	September 30,		December 31,
	2019		2018
Securities sold under agreements to repurchase	$	32,290	$	34,166
Line of credit		—		—
Total	$	32,290	$	34,166

Securities sold under agreements to repurchase represent a demand deposit product offered to customers that sweep balances in excess of the FDIC insurance limit into overnight repurchase agreements. The Company pledges securities as collateral for the repurchase agreements. Refer to Note 4—Securities for additional discussion.

On October 13, 2016, the Company entered into a $30.0 million credit agreement with a correspondent bank. In April 2017, the revolving line of credit was amended to a non-revolving line of credit as long as the outstanding balance exceeds $5.0 million. When the outstanding balance is reduced to $5.0 million, the line of credit will be converted to a revolving line of credit with credit availability up to $5.0 million until maturity. In July 2017, the Company repaid the outstanding balance, in full, under this line of credit of $16.2 million with proceeds from its initial public offering (“IPO”). The line of credit matured on October 10, 2019 and carried an interest rate at either the London Interbank Offered Rate (“LIBOR”) plus 225 basis points or the Prime Rate minus 50 basis points, based on the Company’s election. On October 10, 2019, the Company entered into a fourth amendment to the revolving credit agreement, which increased the revolving loan commitment to $15.0 million and extended the maturity of the credit facility to October 9, 2020. The amended revolving line of credit bears interest at either the LIBOR plus 195 basis points or the Prime Rate minus 75 basis points, based on the Company’s election, which is required to be communicated at least three business days prior to the commencement of an interest period. If the Company fails to provide timely notification, the interest rate will be Prime Rate minus 75 basis points. At September 30, 2019 and December 31, 2018, the line of credit had no outstanding balance, therefore an interest rate option has not been selected.

On April 30, 2019, the Company drew on the line of credit for $5.7 million and selected the LIBOR plus 225 basis points interest rate option, which was the interest rate option at the time of the draw. The funds were utilized to repay a line of credit assumed as a result of the Oak Park River Forest acquisition. The Company repaid the $5.7 million outstanding balance of the line of credit in full on May 31, 2019.

Beginning on June 30, 2008, the interest rate reset to the five-year LIBOR plus 3.50% (6.38% at September 30, 2019 and December 31, 2018), which is in effect until June 30, 2023 and updated every five years. Interest is paid on a quarterly basis. The Company has the right to redeem the debentures, in whole or in part, on any interest payment date on or after June 30, 2008. There was no accrued interest payable as of September 30, 2019 or December 31, 2018.

As part of the First Evanston acquisition, the Company assumed the obligations to First Evanston Bancorp Trust I of $10.0 million in principal amount, which was formed for the issuance of trust preferred securities. Refer to Note 3—Acquisitions for additional information. Beginning on March 15, 2010, the interest rate reset to the three-month LIBOR plus 1.78% (3.90% and 4.57% at September 30, 2019 and December 31, 2018, respectively), which is in effect until the debentures mature in 2035. Interest is paid on a quarterly basis. The Company has the right to redeem the debentures, in whole or in part, on any interest payment date on or after March 2010. The Company has the option to defer interest payments on the debentures from time to time for a period not to exceed five consecutive years. Accrued interest payable was $17,000 and $21,000 as of September 30, 2019 and December 31, 2018, respectively.

The Trusts are not consolidated with the Company. Accordingly, the Company reports the subordinated debentures held by the Trusts as liabilities. The Company owns all of the common securities of each trust. The junior subordinated debentures qualify, and are treated as, Tier 1 regulatory capital of the Company subject to regulatory limitations. The trust preferred securities issued by each trust rank equally with the common securities in right of payment, except that if an event of default under the indenture governing the notes has occurred and is continuing, the preferred securities will rank senior to the common securities in right of payment.

Operating lease commitment s —The Company has entered into various operating lease agreements primarily for facilities and land on which banking facilities are located. Certain lease agreements have renewal options at the end of the original lease term and certain lease agreements have escalation clauses in the rent payments.

The minimum annual rental commitments for operating leases subsequent to September 30, 2019, exclusive of taxes and other charges, are summarized as follows:

	Minimum Rental Commitments
2019	$	1,166
2020		4,455
2021		3,798
2022		2,230
2023		1,294
Thereafter		3,303
Total	$	16,246

The Company’s rental expenses for the nine months ended September 30, 2019 and 2018 were $4.2 million. Rental expenses for the three months ended September 30, 2019 and 2018 were $1.4 million. During t he nine months ended September 30, 2019 and 2018, the Company received $560,000 and $569,000, respectively, in sublease income which is included in the C onsolidated Statements of Operations as a reduction of occupancy expense. Sublease income for the three months ended September 30, 2019 and 2018 was $190,000 and $223,000, respectively. The total amount of minimum rentals to be received in the future on these subleases is approximately $1.3 million, and the leases have contractual lives extending through 2025. In addition to the above required lease payments, the Company has contractual obligations related primarily to information technology contracts and other maintenance contracts. In June 2018, the Company accrued $8.1 million in data processing expense primarily related to contract termination with its core service provider in anticipation of a future system conversion . As of September 30, 2019, there was no remaining contract termination balance.

Commitments to extend credi t —The Company is party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit and standby letters of credit. Those instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the Consolidated Statements of Financial Condition. The contractual or notional amounts of those instruments reflect the extent of involvement the Company has in particular classes of financial instruments.

The Company’s exposure to credit loss in the event of non-performance by the other party to the financial instrument for commitments to extend credit and letters of credit is represented by the contractual or notional amount of those instruments. The Company uses the same credit policies in making commitments and conditional obligations as it does for funded instruments. The Company does not anticipate any material losses as a result of the commitments and letters of credit.

The following table summarizes the contract or notional amount of outstanding loan and lease commitments at September 30, 2019 and December 31, 2018 :

Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amount does not necessarily represent future cash requirements. The Company evaluates each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Company upon extension of credit, is based on management’s credit evaluation of the counterparty. Collateral is primarily obtained in the form of commercial and residential real estate (including income producing commercial properties).

Letters of credit are conditional commitments issued by the Company to guarantee to a third-party the performance of a customer. Those guarantees are primarily issued to support public and private borrowing arrangements, bond financing and similar transactions. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers.

Commitments to make loans are generally made for periods of 90 days or less. The fixed rate loan commitments have interest rates ranging from 2.50% to 19.50% and maturities up to 2042. Variable rate loan commitments have interest rates ranging from 2.02% to 10.25% and maturities up to 2048.

Note 16—Fair Value Measurement

Fair value is the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. In addition, the Company has the ability to obtain fair values for markets that are not accessible.

These types of inputs create the following fair value hierarchy:

Level 1 —Quoted prices in active markets for identical assets or liabilities.

Level 2 —Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active and model-derived valuations whose inputs are observable or whose significant value drivers are observable.

Level 3 —Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the asset or liability. Unobservable inputs are used to measure fair value to the extent that observable inputs are not available. The Company’s own data used to develop unobservable inputs may be adjusted for market considerations when reasonably available.

The categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to assets and liabilities.

The Company used the following methods and significant assumptions to estimate fair value for certain assets measured and carried at fair value on a recurring basis:

BYLINE BANCORP, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Table dollars in thousands, except share and per share data) (Unaudited)

Securities available-for-sal e —The Company obtains fair value measurements from an independent pricing service. Management reviews the procedures used by the third party, including significant inputs used in the fair value calculations. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the bond’s terms and conditions, among other things. When market quotes are not readily accessible or available, alternative approaches are utilized, such as m atrix or model pricing.

The Company’s methodology for pricing non-rated bonds focuses on three distinct inputs: equivalent rating, yield and other pricing terms. To determine the rating for a given non-rated municipal bond, the Company references a publicly issued bond by the same issuer if available as well as other additional key metrics to support the credit worthiness. Typically, pricing for these types of bonds would require a higher yield than a similar rated bond from the same issuer. A reduction in price is applied to the rating obtained from the comparable bond, as the Company believes if liquidated, a non-rated bond would be valued less than a similar bond with a verifiable rating. The reduction applied by the Company is one notch lower (i.e. a “AA” rating for a comparable bond would be reduced to “AA-” for the Company’s valuation). In 2019 and 2018, all of the ratings derived by the Company were “BBB” or better with and without comparable bond proxies. The fair value measurement of municipal bonds is sensitive to the rating input, as a higher rating typically results in an increased valuation. The remaining pricing inputs used in the bond valuation are observable. Based on the rating determined, the Company obtains a corresponding current market yield curve available to market participants. Other terms including coupon, maturity date, redemption price, number of coupon payments per year, and accrual method are obtained from the individual bond term sheets.

Equity and other securities —The Company utilizes the same fair value measurement methodology for equity and other securities as detailed in the securities available-sale portfolio above.

Servicing asset s —Fair value is based on a loan-by-loan basis taking into consideration the original term to maturity, the current age of the loan and the remaining term to maturity. The valuation methodology utilized for the servicing assets begins with generating estimated future cash flows for each servicing asset, based on their unique characteristics and market-based assumptions for prepayment speeds and costs to service. The present value of the future cash flows are then calculated utilizing market-based discount rate assumptions.

Derivative instrument s —Interest rate derivatives are valued by a third party, using models that primarily use market observable inputs, such as yield curves, and are validated by comparison with valuations provided by the respective counterparties. Derivative financial instruments are included in other assets and other liabilities in the Consolidated Statements of Financial Condition.

		Discount rate	4.8%—24.0%	12.2%	Decrease
		Expected weighted average loan life	0.1—9.5 years	4.5 years	Increase

The Company used the following methods and significant assumptions to estimate fair value for certain assets measured and carried at fair value on a non-recurring basis:

Impaired loans (excluding acquired impaired loans ) —Impaired loans, other than those existing on the date of a business acquisition, are primarily carried at the fair value of the underlying collateral, less estimated costs to sell, if the loan is collateral dependent. Valuations of impaired loans that are collateral dependent are supported by third party appraisals in accordance with the Bank’s credit policy. Other valuation methods include analysis of discounted cash flows, which measures the present value of expected future cash flows discounted at the loan’s effective interest rate. Impaired loans that are not collateral dependent are not material.

Assets held for sal e —Assets held for sale consist of former branch locations and real estate previously purchased for expansion. Assets are considered held for sale when management has approved to sell the assets following a branch closure or other events. The properties are being actively marketed and transferred to assets held for sale based on the lower of carrying value or its fair value, less estimated costs to sell.

BYLINE BANCORP, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Table dollars in thousands, except share and per share data) (Unaudited)

Other real estate owne d —Certain assets held within other real estate owned represent real estate or other collateral that has been adjusted to its estimated fair value, less cost to sell, as a result of transferring from the loan portfolio at the time of foreclosure or repossession and based on management’s periodic impairment evaluation. From time to time, non-recurring fair value adjustments to other real estate owned are recorded to reflect partial write-downs based on an observable market price or current appraised value of property.

Adjustments to fair value based on such non-recurring transactions generally result from the application of lower-of-cost-or-market accounting or write-downs of individual assets due to impairment. The following tables summarize the Company’s assets that were measured at fair value on a non-recurring basis, excluding acquired impaired loans, as of September 30, 2019 and December 31, 2018:

The following methods and assumptions were used by the Company in estimating fair values of other assets and liabilities for disclosure purposes:

Cash and cash equivalent s —For these short-term instruments, the carrying amount is a reasonable estimate of fair value.

Securities held-to-maturit y —The Company obtains fair value measurements from an independent pricing service. Management reviews the procedures used by the third party, including significant inputs used in the fair value calculations. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the bond’s terms and conditions, among other things. When market quotes are not readily accessible or available, alternative approaches are utilized, such as matrix or model pricing.

Restricted stoc k —The fair value has been determined to approximate cost.

Loans held for sale — The fair value of loans held for sale are based on quoted market prices, where available, and determined by discounted estimated cash flows using interest rates approximating the Company’s current origination rates for similar loans adjusted to reflect the inherent credit risk.

BYLINE BANCORP, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Table dollars in thousands, except share and per share data) (Unaudited)

Loan and lease receivables, net —For certain variable rate loans that reprice frequently and with no significant changes in credit risk, fair value is estimated at carrying value. The fair value of other types of loans is estimated using an exit price notion for 2019 values. It is estimated by discounting future cash flows, using current rates at which similar loans would be made to borrowers with similar credit ratings and for the same remaining maturities.

Deposits —The fair value of demand deposits, savings accounts, and certain money market deposits is the amount payable on demand at the reporting date. The fair value of fixed-maturity certificates of deposit is estimated by discounting future cash flows, using rates currently offered for deposits of similar remaining maturities.

Federal Home Loan Bank advances —The fair value of FHLB advances is estimated by discounting the agreements based on maturities using rates currently offered for FHLB advances of similar remaining maturities adjusted for prepayment penalties that would be incurred if the borrowings were paid off on the measurement date.

Securities sold under agreements to repurchas e —The carrying amount approximates fair value due to maturities of less than ninety days.

Junior subordinated debenture s —The fair value of junior subordinated debentures, in the form of trust preferred securities, is determined using rates currently available to the Company for debt with similar terms and remaining maturities.

Accrued interest receivable and payable —The carrying amount approximates fair value.

Commitments to extend credit and letters of credi t —The fair values of these off-balance sheet commitments to extend credit and commercial and letters of credit are not considered practicable to estimate because of the lack of quoted market prices and the inability to estimate fair value without incurring excessive costs.

The estimated fair values of financial instruments not carried at fair value and levels within the fair value hierarchy are as follows:

Note 17—Derivative Instruments and Hedge Activities

The Company recognizes derivative financial instruments at fair value regardless of the purpose or intent for holding the instrument. The Company records derivative assets and derivative liabilities on the Consolidated Statements of Financial Condition within accrued interest receivable and other assets and accrued interest payable and other liabilities, respectively. The following tables present the fair value of the Company’s derivative financial instruments and classification on the Consolidated Statements of Financial Condition as of September 30, 2019 and December 31, 2018:

Interest rate swaps designated as cash flow hedges —Cash flow hedges of interest payments associated with certain FHLB advances had notional amounts totaling $250.0 million as of December 31, 2018. There were no cash flow hedges outstanding at September 30, 2019. The Company assesses the effectiveness of each hedging relationship by comparing the changes in fair value of the derivative hedging instrument with the changes in fair value of the designated hedged transactions. In September 2019, the Company terminated $250.0 million interest rate swaps designated as cash flow hedges, which were executed to reduce interest rate risk in a declining rate environment. The transaction resulted in a net loss of $383,000, net of tax, which was the clean value at the termination date. As of September 30, 2019, the remaining balance in accumulated other comprehensive income was $378,000, which will be amortized over the original life of the cash flow hedge.

Interest recorded on these swap transactions reduced FHLB interest expense by $364,000 and $428,000 during the three months ended September 30, 2019 and 2018, respectively, and is reported as a component of interest expense on FHLB advances. Interest recorded on these swap transactions reduced FHLB interest expense by $1.6 million and $863,000 during the nine months ended September 30, 2019 and 2018, respectively. At September 30, 2019, the Company estimates $85,000 of the unrealized loss to be reclassified as an increase to interest expense during the next twelve months.

The following table reflects the net gains (losses) recorded in accumulated other comprehensive income (loss) and the Consolidated Statements of Operations relating to the cash flow derivative instruments for the nine months ended:

Weighted average maturity	6.8 years

Other credit derivatives— The total notional amount was $9.5 million and $4.4 million as of September 30, 2019 and December 31, 2018, respectively. The fair value of the other credit derivatives are reflected in other liabilities with corresponding gains or losses reflected in non-interest income. The credit valuation adjustment (“CVA”) related to the other credit derivatives resulted in a decrease to other non-interest income of $7,000 and $1,000 during the three months ended September 30, 2019 and 2018, respectively. There were $73,000 and $35,000 of transaction fees included in non-interest income related to these derivative instruments during the three months ended September 30, 2019 and 2018, respectively.

There were $73,000 and $61,000 of transaction fees included in non-interest income related to these derivative instruments during the nine months ended September 30, 2019 and 2018, respectively.

The Company has entered into risk participation agreements with counterparty banks to assume a portion of the credit risk related to borrower transactions. The credit risk related to these other credit derivatives is managed through the Company’s loan underwriting process.

Credit risk —Derivative instruments are inherently subject to market risk and credit risk. Market risk is associated with changes in interest rates and credit risk relates to the Company’s risk of loss when the counterparty to a derivative contract fails to perform according to the terms of the agreement. Market and credit risks are managed and monitored as part of the Company’s overall asset-liability management process. The credit risk related to derivatives entered into with certain qualified borrowers is managed through the Company’s loan underwriting process. The Company’s loan underwriting process also approves the Bank’s swap counterparty used to mirror the borrowers’ swap. The Company has a bilateral agreement with each swap counterparty that provides that fluctuations in derivative values are to be fully collateralized with either cash or securities. The CVA is a fair value adjustment to the derivative to account for this risk. During the three months ended September 30, 2019, the CVA resulted in a decrease to non-interest income of $219,000. During the three months ended September 30, 2018, CVA resulted in an increase to non-interest income of $13,000. During the nine months ended September 30, 2019 and 2018, the CVA resulted in a decrease to non-interest income of $592,000 and $25,000, respectively.

The Company has agreements with its derivative counterparties that contain a cross-default provision under which if the Company defaults on any of its indebtedness, including default where repayment of the indebtedness has not been accelerated by the lender, then the Company could also be declared in default on its derivative obligations. The Company also has agreements with certain derivative counterparties that contain a provision where if the Company fails to maintain its status as a well or adequately capitalized institution, then the counterparty could terminate the derivative positions and the Company would be required to settle its obligations resulted in a net asset position.

In October 2014, the Company adopted the Byline Bancorp, Inc. Equity Incentive Plan (“BYB Plan”). The maximum number of shares a vailable for grants under this p lan was 2,476,122 shares. During 2016 and 2015, the Company granted options to purchase 212,400 and 1,634,568 shares, respectively, under this plan. The Company did not grant any stock options during the year ended December 31, 2017 . In June 2017, the Board of Directors terminated the BYB Plan and no future grants can be made under this plan . Options to purchase a total of 1, 4 49 , 072 shares remain outstanding under the BYB Plan at September 30, 2019 .

The types of stock options granted under the BYB Plan were Time Options and Performance Options. The exercise price of each option is equal to the fair value of the stock as of the date of grant. These option awards have vesting periods ranging from one to five years and have 10-year contractual terms. Stock volatility was computed as the average of the volatilities of peer group companies.

The vesting of Time Options is conditional based on completion of service. Performance Options have conditional vesting based on either performance targets or market performance. Certain Performance Options’ performance goals will be satisfied (in whole or in part) if the Bank achieves various performance targets such as profitability, asset quality, and conditional based on market performance, as outlined in the BYB Plan. Each of the performance goals identified are measured for achievement (or failure to achieve) independent of each other. In October 2017, the Board of Directors determined that the Performance Option goals were satisfied, in whole, and these Performance Options converted to Time Options. As a result of the previous completion of service, 414,894 performance options vested on October 3, 2017.

The fair values of the stock options were determined using the Black-Scholes-Merton model for Time Options and a Monte Carlo simulation model for Performance Options.

The words “the Company,” “we,” “Byline,” “our” and “us” refer to Byline Bancorp, Inc. and its consolidated subsidiaries, unless we indicate otherwise.

Overview

Our business

We are a bank holding company headquartered in Chicago, Illinois and conduct all our business activities through our subsidiary, Byline Bank, a full service commercial bank, and Byline Bank’s subsidiaries. Through Byline Bank, we offer a broad range of banking products and services to small and medium sized businesses, commercial real estate and financial sponsors and to consumers who generally live or work near our branches. In addition to our traditional commercial banking business, we provide small ticket equipment leasing solutions through Byline Financial Group, a wholly-owned subsidiary of Byline Bank, headquartered in Bannockburn, Illinois with sales offices in Illinois and New York, and sales representatives in Illinois, Michigan, New Jersey, and New York. Following our acquisition of Ridgestone Financial Services, Inc. (“Ridgestone”) in October 2016, we also participate in U.S. government guaranteed lending programs and originate U.S. government guaranteed loans. Byline Bank was the fifth most active originator of SBA loans in the country and the most active SBA lender in Illinois and Wisconsin, as reported by the SBA for the quarter ended September 30, 2019. Following our acquisition of First Evanston Bancorp, Inc. (“First Evanston”) and its subsidiary bank, First Bank & Trust, at the end of May 2018, we also provide trust and wealth management services to our customers. As of September 30, 2019, we had consolidated total assets of $5.4 billion, total gross loans and leases outstanding of $3.8 billion, total deposits of $4.1 billion, and total stockholders’ equity of $735.9 million.

Ridgestone Acquisition

On October 14, 2016, we completed the acquisition of Ridgestone under the terms of a definitive merger agreement. As of the acquisition date, Ridgestone had $447.4 million in assets, including $347.3 million of loans, $14.7 million of loans held for sale, $27.2 million of securities, $21.5 million of servicing assets and total deposits of $358.7 million. Ridgestone’s loan portfolio was primarily comprised of the retained unguaranteed portion of U.S. government guaranteed loans as a participant in the SBA and USDA (together, “U.S. government guaranteed”) lending programs.

First Evanston Acquisition

On May 31, 2018, we completed the acquisition of First Evanston under the terms of a definitive merger agreement. As a result of the merger, First Evanston’s wholly owned bank subsidiary, First Bank & Trust, was merged with and into Byline Bank. As of the acquisition date, First Evanston had $1.1 billion in assets, including $932.4 million of loans, $128.1 million of securities, and total deposits of $1.0 billion.

At the effective time of the merger (the “Effective Time”), each share of First Evanston’s common stock (the “First Evanston Common Stock”) was converted into the right to receive: (1) 3.994 shares of Byline’s common stock, and (2) an amount in cash equal to $27.0 million divided by the number of outstanding shares of First Evanston Common Stock as of the closing date, with cash paid in lieu of any fractional shares. Options to acquire First Evanston Common Stock that were outstanding at the Effective Time were converted into options of substantially equivalent value to acquire Byline common stock. In the aggregate, Byline paid $27.0 million in cash and issued 6,682,850 shares of its common stock in respect of the outstanding shares of First Evanston Common Stock. The value of the total merger consideration at closing was approximately $179.1 million.

As of the acquisition date, Oak Park River Forest had $329.8 million in assets, including $30.5 million of securities, $274.7 million of loans, and $290.2 million of deposits.

At the effective time of the merger, each share of Oak Park River Forest’s common stock was converted into the right to receive: (1) 7.9321 shares of Byline’s common stock, and (2) an amou nt in cash equal to $6.2 million divided by the number of outstanding shares of Oak Park River Forest common stock as of the closing date, with cash paid in lieu of fractional shares. Options to acquire Oak Park River Forest common stock that were outstand ing at the Effective Time were paid in cash based on elections made by option holders, resulting in an aggregate stock options transaction value of $4.2 million. In the aggregate, Byline paid $6.2 million in cash and issued 1,464,558 shares of its common s tock in respect of the outstanding shares of Oak Park River Forest common stock. The value of the total merger consideration at closing was approximately $35.5 million before issuance costs of $429,000 .

Strategic Branch Consolidation

We continually perform strategic reviews of our existing banking footprint. With technology improvements and changes to customers’ banking preferences, we examine branch growth potential, customer usage, branch profitability, services provided, markets served and proximity to other locations with a goal of minimizing customer impact and deposit runoff. Since our recapitalization, which occurred in June 2013, our branch network has been reduced from 88 to 61, including eight branches added through the First Evanston acquisition and three branches added through the Oak Park River Forest acquisition. During 2018 and 2019, we consolidated seven branches and two other facilities within our current network that had a minimal impact on our customer service levels, convenience, and business development capabilities. Additionally, this quarter we identified another three branches that we believe can be consolidated and one that we believe can be repurposed with minimal customer impact, service levels, and overall convenience. We expect these activities to occur during the first quarter of 2020. We expect to record a one-time charge of approximately $817,000 and to generate $1.2 million in annual cost savings as a result of this consolidation, a portion of which we will look to reinvest back into the business.

We plan to continue to leverage our seasoned management team, the attractive market opportunity in the Chicago metropolitan area, our diversified lending approach and our track record of successfully integrating acquisitions to drive future growth. We believe that having a deep understanding of customers, longstanding ties to the communities in which we operate, a strong market position and exceptional employees allows us to provide the attention, responsiveness and customized service our clients seek while offering a diverse range of products to serve a variety of needs.

Critical Accounting Policies and Significant Estimates

Our accounting and reporting policies conform to accounting principles generally accepted in the United States (“GAAP”) and to general practices within the Banking industry. To prepare financial statements and interim financial statements in conformity with GAAP, management makes estimates, assumptions and judgments based on available information. These estimates, assumptions and judgments affect the amounts reported in the financial statements and accompanying notes; and are based on information available as of the date of the financial statements. As this information changes, actual results could differ from the estimates, assumptions and judgments reflected in the financial statements. In particular, management has identified several accounting policies that, due to the estimates, assumptions and judgements inherent in those policies, are critical in understanding our financial statements.

These critical accounting policies and estimates include (i) acquisition‑related fair value computations, (ii) the carrying value of loans and leases, (iii) determining the provision and allowance for loan and lease losses, (iv) the valuation of intangible assets such as goodwill, servicing assets and core deposit intangibles, (v) the determination of fair value for financial instruments, including other-than-temporary-impairment losses, (vi) the valuation of real estate held for sale, and (vii) the valuation of or recognition of deferred tax assets and liabilities.

The Jumpstart Our Business Startups Act of 2012, or the JOBS Act, permits us an extended transition period for complying with new or revised accounting standards affecting public companies. We have elected to take advantage of this extended transition period, which means that the financial statements included in this report, as well as any financial statements that we file in the future, will not be subject to all new or revised accounting standards generally applicable to public companies for the transition period for so long as we remain an emerging growth company or until we affirmatively and irrevocably opt out of the extended transition period provided for under the JOBS Act.

The following is a discussion of the critical accounting policies and significant estimates that require us to make complex and subjective judgments. Additional information about these policies can be found in Note 1 of our audited

Co nsolidated Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 2018, that we file d with the Securities and Exchange Commission (“ SEC ”) on March 15, 2019 .

Business Combinations

We account for business combinations under the acquisition method of accounting in accordance with ASC 805. We recognize the fair value of the assets acquired and liabilities assumed as of the date of acquisition, with any excess of the fair value of consideration provided over the fair value of the identifiable net tangible and intangible assets acquired recorded as goodwill. Transaction costs are expensed as incurred. Application of the acquisition method requires extensive use of accounting estimates and judgements to determine the fair values of the identifiable assets acquired and liabilities assumed at the acquisition date.

In accordance with ASC 805, the acquiring company retains the right to make appropriate adjustments to the assets and liabilities of the acquired entity for information obtained during the measurement period about facts and circumstances that existed as of the acquisition date. The measurement period ends as of the earlier of (i) one year from the acquisition date or (ii) the date when the acquirer receives the information necessary to complete the business combination accounting.

Carrying Value of Loans and Leases

Our accounting methods for loans and leases differ depending on whether they are new or acquired loans and leases; and for acquired loans, whether the loans were acquired at a discount as a result of credit deterioration since the date of origination.

Originated Loans and Leases

We account for originated loans and leases and purchased loans and leases not acquired through business combinations as originated loans and leases. The new loans that management has the intent and ability to hold for the foreseeable future are reported at their outstanding principal balances net of any allowance for loan and lease losses, unamortized deferred fees and costs and unamortized premiums or discounts. The net amount of nonrefundable loan origination fees and certain direct costs associated with the lending process are deferred and amortized to interest income over the contractual lives of the new loans using methods which approximate the level yield method. Discounts and premiums are amortized or accreted to interest income over the estimated term of the new loans using methods that approximate the effective yield method. Interest income on new loans is accrued based on the unpaid principal balance outstanding. Additionally, once an acquired non-impaired loan reaches its contractual maturity date, it is re-underwritten, and if renewed, it is classified as an originated loan.

Acquired Loans and Leases

Acquired loans and leases are recorded at fair value as of the acquisition date. Credit discounts are included in the determination of fair value; therefore, an allowance for loan and lease losses is not recorded at the acquisition date. Acquired loans are evaluated upon acquisition and classified as either acquired impaired or acquired non‑impaired. Acquired impaired loans reflect evidence of credit deterioration since origination for which it is probable that all contractually required principal and interest will not be collected by us. Subsequent to acquisition, we periodically update for changes in cash flow expectations, which are reflected in interest income over the life of the loan as accretable yield. Any subsequent decreases in expected cash flow attributable to credit deterioration are recognized by recording a provision for loan losses.

For acquired non‑impaired loans and leases, the excess or deficit of the loan and lease principal balance over the fair value is recorded as a discount or premium at acquisition and is accreted through interest income over the life of the loan or lease. Subsequent to acquisition, these loans and leases are evaluated for credit deterioration and a provision for loan and lease losses would be recorded when probable loss is incurred. These loans and leases are evaluated for impairment consistent with originated loans and leases.

Provision and Allowance for Loan and Lease Losses

The provision for loan and lease losses reflects the amount required to maintain the allowance for loan and lease losses (“ALLL”) at an appropriate level based upon management’s evaluation of the adequacy of general and specific loss reserves.

The ALLL is maintained at a level that management believes is appropriate to provide for known and inherent incurred loan and lease losses as of the dates of the Consolidated Statements of Financial Condition, and we have established methodologies for the determination of its adequacy. The methodologies are set forth in a formal policy and take into consideration the need for an overall general valuation allowance as well as specific allowances that are determined on an

individual loan basis. We increase our ALLL by charging provisions for probable losses against our income and decreased by charge ‑offs, net of recoveries.

The evaluation is inherently subjective, as it requires estimates that are susceptible to significant revision as more information becomes available. While management uses available information to recognize losses on loans and leases, changes in economic or other conditions may necessitate revision of the estimate in future periods.

The ALLL is maintained at a level management believes is sufficient to provide for probable losses based upon an ongoing review of the originated and acquired non‑impaired loan and lease portfolios by portfolio category, which include consideration of actual loss experience, peer loss experience, changes in the size and risk profile of the portfolio, identification of individual problem loan and lease situations which may affect a borrower’s ability to repay, and evaluation of prevailing economic conditions.

For acquired impaired loans, a specific valuation allowance is established when it is probable that we will be unable to collect all of the cash flows expected at acquisition, plus the additional cash flows expected to be collected arising from changes in estimates after acquisition.

The originated and non‑impaired acquired loans have limited delinquency and credit loss history and have not yet exhibited an observable loss trend. The credit quality of loans in these loan portfolios are impacted by delinquency status and debt service coverage generated by the borrowers’ businesses and fluctuations in the value of real estate collateral.

Acquired non‑impaired loans and originated loans are considered impaired when, based on current information and events, it is probable that we will be unable to collect the scheduled payments of principal or interest when due, according to the contractual terms of the loan agreements. All acquired non‑impaired loans and originated loans of $100,000 or greater with an internal risk rating of substandard or below and on nonaccrual, as well as loans classified as troubled debt restructurings (“TDR”), are reviewed individually for impairment on a quarterly basis.

Goodwill and Other Intangible Assets

Goodwill

Goodwill represents the excess of the purchase consideration over the fair value of net assets acquired in connection with our recapitalization and acquisitions using the acquisition method of accounting. Goodwill is not amortized but is periodically evaluated for impairment under the provisions of ASC Topic 350, Intangibles—Goodwill and Other (“ASC 350”).

Impairment testing is performed using either a qualitative or quantitative approach at the reporting unit level. Our goodwill is allocated to Byline Bank, which is our only applicable reporting unit for the purposes of testing goodwill for impairment. We have selected November 30 as the date to perform the annual goodwill impairment test. Additionally, we perform a goodwill impairment evaluation on an interim basis when events or circumstances indicate impairment potentially exists.

Servicing Assets

Servicing assets are recognized separately when they are acquired through sales of loans or when the rights to service loans are purchased. When loans are sold with servicing rights retained, servicing assets are recorded at fair value in accordance with ASC Topic 860, Transfers and Servicing (“ASC 860”). Fair value is based on market prices for comparable servicing contracts, when available, or alternatively, is based on a valuation model that calculates the present value of estimated future net servicing income. The fair value of servicing rights is highly sensitive to changes in underlying assumptions. Changes in the prepayment speed and discount rate assumptions have the most significant impact on the fair value of servicing rights. See Note 7 and Note 16 of our Unaudited Interim Condensed Consolidated Financial Statements as of September 30, 2019, included in this report, for additional information.

Core Deposit Intangible Assets

Other intangible assets primarily consist of core deposit intangible assets. In valuing core deposit intangibles, we consider variables such as deposit servicing costs, attrition rates and market discount rates. Core deposit intangibles are reviewed annually, or more frequently when events or changes in circumstances occur that indicate that their carrying values may not be recoverable. If the recoverable amount of the core deposit intangibles is determined to be less than its carrying value, we would then measure the amount of impairment based on an estimate of the fair value at that time. We also evaluate whether the events or circumstances have occurred that warrant a revision to the remaining useful lives of intangible assets.

In cases where a revision is deemed appropriate, the remaining carrying amounts of the intangible as sets are amortized over the revised remaining useful life. Core deposit intangibles are currently amortized over a n approximate ten year period.

Customer Relationship Intangible

Other intangible assets also include our customer relationship intangible asset. In valuing our customer relationship intangibles, we consider variables such as assets under management, attrition rates, and fee structure. Customer relationship intangibles are currently amortized over a 12 year period.

Fair value of Financial Instruments

ASC Topic 820, Fair Value Measurement defines fair value as the price that would be received to sell a financial asset or paid to transfer a financial liability in an orderly transaction between market participants at the measurement date.

The degree of management judgment involved in determining the fair value of assets and liabilities is dependent upon the availability of quoted market prices or observable market parameters. For financial instruments that trade actively and have quoted market prices or observable market parameters, there is minimal subjectivity involved in measuring fair value. When observable market prices and parameters are not available, management judgment is necessary to estimate fair value. In addition, changes in market conditions may reduce the availability of quoted prices or observable data. For example, reduced liquidity in the capital markets or changes in secondary market activities could result in observable market inputs becoming unavailable. Therefore, when market data is not available, we would use valuation techniques requiring more management judgment to estimate the appropriate fair value measurement.

See Note 18 of Byline’s Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 2018, for a complete discussion of our use of fair value of financial assets and liabilities and their related measurement practices.

Valuation of Real Estate Held for Sale

Other Real Estate Owned (OREO)

OREO includes real estate assets that have been acquired through, or in lieu of, loan foreclosure or repossession and are to be sold. OREO assets are initially recorded at fair value, less estimated costs to sell, of the collateral of the loan, on the date of foreclosure or repossession, establishing a new cost basis. Adjustments that reduce loan balances to fair value at the time of foreclosure or repossession are recognized as charge‑offs in the allowance for loan and lease losses. Positive adjustments, if any, at the time of foreclosure or repossession are recognized in non‑interest expense. After foreclosure or repossession, management periodically obtains new valuations and real estate or other assets may be adjusted to a lower carrying amount, determined by the fair value of the asset, less estimated costs to sell. Any subsequent write‑downs are recorded as a decrease in the asset and charged against other real estate owned valuation adjustments, included within non-interest expense. Operating expenses of such properties, net of related income, are included in non‑interest expense, and gains and losses on their disposition are included in non‑interest expense. Gains on internally financed other real estate owned sales are accounted for in accordance with the methods stated in ASC Topic 360‑20, Real Estate Sales (“ASC 360‑20”). Any losses on the sales of other real estate owned properties are recognized immediately.

Assets Held for Sale

Assets held for sale consist of former branch locations and real estate purchased for expansion. Assets are considered held for sale when management has approved a plan to sell the assets following a branch closure or other events. The properties are being actively marketed and transferred to assets held for sale based at the lower of its carrying value or its fair value, less estimated costs to sell. Adjustments to reduce the asset balances to fair value are recorded at the time of transfer and are recognized through a charge against income. An assessment of the recoverability of other long-lived assets associated with all branches is periodically performed, resulting in impairment losses which are reflected in other non-interest expense.

Income Taxes

We use the asset and liability method to account for income taxes. The objective of the asset and liability method is to establish deferred tax assets and liabilities for the temporary differences between the financial reporting basis and the income tax basis of our assets and liabilities at enacted tax rates expected to be in effect when such amounts are realized or settled. Our annual tax rate is based on our income, statutory tax rates and available tax planning opportunities. Tax laws are complex and subject to different interpretations by the taxpayer and respective governmental taxing authorities. Significant judgment is required in determining tax expense and in evaluating tax positions, including evaluating uncertainties.

Deferred income tax assets represent amounts available to reduce income taxes payable on taxable income in future years. Such assets arise because of temporary differences between the financial reporting and tax bases of assets and liabilities, as well as from net operating loss carryforwards. We review our deferred tax positions quarterly for changes which may impact realizability. We evaluate the recoverability of these future tax deductions by assessing the adequacy of future expected taxable income from all sources, including reversal of taxable temporary differences, forecasted operating earnings and available tax planning strategies. We use short and long‑range business forecasts to provide additional information for its evaluation of the recoverability of deferred tax assets. It is our policy to recognize interest and penalties associated with uncertain tax positions, if applicable, as components of non‑interest expense.

A deferred tax valuation allowance is established to reduce the net carrying amount of deferred tax assets if it is determined to be more likely than not that all or some of the deferred tax asset will not be realized. See Note 11 of the notes to our Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 2018, for further information on income taxes.

Recently Issued Accounting Pronouncements

Refer to Note 2 of our Unaudited Interim Condensed Consolidated Financial Statements as of September 30, 2019, included in this report, for a description of recent accounting pronouncements, including the effective dates of adoption and anticipated effects on our results of operations and financial condition.

Primary Factors Used to Evaluate Our Business

As a financial institution, we manage and evaluate various aspects of both our results of operations and our financial condition. We evaluate the levels and trends of the line items included in our consolidated balance sheet and income statement as well as various financial ratios that are commonly used in our industry. We analyze these ratios and financial trends against our own historical performance, our budgeted performance and the final condition and performance of comparable financial institutions in our region. Comparison of our financial performance against other financial institutions is impacted by the accounting for acquired non‑impaired and acquired impaired loans.

These factors and metrics described in this prospectus may not provide an appropriate basis to compare our results or financial condition to the results or financial condition of other financial services companies, given our limited operating history and strategic acquisitions since our recapitalization.

Results of Operations

Overview

Our results of operations depend substantially on net interest income, which is the difference between interest income on interest-earning assets, consisting primarily of interest income on loans and lease receivables, including accretion income on loans, investment securities and other short-term investments, and interest expense on interest-bearing liabilities, consisting primarily of deposits and borrowings. Our results of operations are also dependent upon our generation of non-interest income, consisting primarily of income from fees and service charges on deposits, loan servicing revenue, wealth management and trust income, ATM and interchange fees, and net gains on sales of investment securities and loans. Other factors contributing to our results of operations include our provisions for loan and lease losses, provision for income taxes, and non-interest expenses, such as salaries and employee benefits, occupancy and equipment expenses and other miscellaneous operating costs.

Our third quarter 2019 results reflect growth in net interest income, primarily driven by the Oak Park River Forest acquisition, organic loan and lease growth, and security purchases. Net interest margin decreased to 4.62% for the third

quarter of 2019 , compared to 4.73% for the third quarter of 2018 . The de crease was primarily due to increased interest exp ense due to the Oak Park River Forest acquisition, increased rates paid on time deposits , and increased costs on FHLB advances . This was partially offset by increased interest i ncome due to an increase in earning assets as a result of the acquisition, organic loan and lease growth, and security purchases . Our total revenues increased by $ 9.1 million , or 14.4 % , compared to the third quarter of 2018 , primarily driven by the acquired Oak Park River Forest loan portfolio , loan and lease originations , and increased loan and lease yields.

We reported consolidated net income of $15.3 million for the three months ended September 30, 2019, compared to net income of $14.5 million for the three months ended September 30, 2018, an increase of $806,000. The increase in net income was primarily attributable to a $5.2 million increase in net interest income and a $3.9 increase in non-interest income, offset by a $7.7 million increase in non-interest expense, a $521,000 increase in provision for income taxes, and an $89,000 increase in provision for loan and lease losses. The increase in net interest income during the three months ended September 30, 2019 was a primarily a result of the acquisition and organic loan and lease growth, offset by increases in interest-bearing deposits cost during the current period. The increase in non-interest income was primarily driven by an increase in net gains on sale of loans. The increase in non-interest expense was primarily due to an increase in salaries and employee benefits of $3.2 million due to organizational growth and a result of the most recent acquisition, an increase in legal, audit and other professional fees of $1.7 million due to increased professional services engagements, and an increase in data processing of $1.3 million due to expenses incurred related to the Oak Park River Forest core system conversion. The increase in provision for income taxes was primarily driven by an increase in net income before provision for income taxes during the period. The increase in provision for loan and lease losses reflects the growth in our loan portfolio, particularly the unguaranteed portion of U.S. government guaranteed loans, the migration of the acquired portfolio into the originated portfolio, and increases to our general reserves.

Net income available to common stockholders was $15.1 million or $0.40 per basic and $0.39 per diluted common share for the three months ended September 30, 2019, compared to $14.3 million or $0.40 per basic and $0.39 per diluted common share for the three months ended September 30, 2018. Dividends on preferred shares were $196,000 for the three months ended September 30, 2019 and 2018.

Our annualized return on average assets was 1.12% for the three months ended September 30, 2019, compared to 1.20% for the three months ended September 30, 2018. Our annualized return on average stockholders’ equity was 8.34% for the three months ended September 30, 2019, compared to 9.22% for the three months ended September 30, 2018. Our efficiency ratio was 59.81% for the three months ended September 30, 2019, compared to 56.41% for the three months ended September 30, 2018.

We reported consolidated net income of $41.2 million for the nine months ended September 30, 2019, compared to net income of $24.1 million for the nine months ended September 30, 2018, an increase of $17.1 million. The increase in net income was primarily attributable to a $37.0 million increase in net interest income and a $4.7 million increase in non-interest income, offset by a $15.3 million increase in non-interest expense, an $8.0 million increase in provision for income taxes, and a $1.4 million increase in provision for loan and lease losses. The increase in net interest income during the nine months ended September 30, 2019 was primarily a result of the Oak Park River Forest acquisition, organic loan and lease growth, and security purchases, offset by increases in the costs of interest-bearing deposits and increases in average FHLB advances during the current period. The increase in non-interest income was primarily driven by a decreased downward loan servicing asset revaluation, security sales during the period, an increase in the fair value of equity securities, net, and the acquisition. The increase in non-interest expense was primarily due to additional costs associated with the acquisitions, primarily salaries and employee benefits, partially offset by a decrease in data processing of $4.3 million due to the core system conversion charges incurred in the second quarter of 2018. The increase in provision for income taxes was primarily driven by an increase in net income before provision for income taxes during the period. The increase in provision for loan and lease losses was primarily driven by increases in the general reserves driven by loan and lease originations.

Net income available to common stockholders was $40.6 million or $1.09 per basic and $1.07 per diluted common share for the nine months ended September 30, 2019, compared to $23.5 million or $0.73 per basic and $0.71 per diluted common share for the nine months ended September 30, 2018. Dividends on preferred shares were $587,000 for the nine months ended September 30, 2019 and 2018.

Our annualized return on average assets was 1.05% for the nine months ended September 30, 2019, compared to 0.80% for the nine months ended September 30, 2018. Our annualized return on average stockholders’ equity was 7.91% for the nine months ended September 30, 2019, compared to 6.01% for the nine months ended September 30, 2018. Our

efficiency ratio was 61.15% for the nine months ended September 30, 2019 , compared to 68.70% for the nine months ended September 30, 2018 .

Net Interest Income

Net interest income, representing interest income less interest expense, is a significant contributor to our revenues and earnings. We generate interest income from interest and dividends on interest-earning assets, which include loans, leases and investment securities we own. We incur interest expense from interest paid on interest-bearing liabilities, which include interest-bearing deposits, FHLB advances, junior subordinated debentures and other borrowings. To evaluate net interest income, we measure and monitor (i) yields on our loans and other interest-earning assets, (ii) the costs of our deposits and other funding sources, (iii) our net interest spread, and (iv) our net interest margin. Net interest spread is the difference between rates earned on interest-earning assets and rates paid on interest-bearing liabilities. Net interest margin is calculated as the annualized net interest income divided by average interest-earning assets. Because non-interest-bearing sources of funds, such as non-interest-bearing deposits and stockholders’ equity, also fund interest-earning assets, net interest margin includes the benefit of these non-interest-bearing sources.

We also recognize income from the accretable discounts associated with the purchase of interest-earning assets. Because of our recapitalization and the acquisitions of Ridgestone, First Evanston, and Oak Park River Forest, we derive a portion of our interest income from the accretable discounts on acquired loans. The accretion is generally recognized over the life of the loan and is impacted by changes in expected cash flows on the loan. This accretion will continue to have an impact on our net interest income as long as loans acquired with a discount at acquisition represent a meaningful portion of our interest-earning assets. As of September 30, 2019, acquired loans with evidence of credit deterioration accounted for under ASC Topic 310-30, Accounting for Purchased Loans with Deteriorated Credit Quality, represented 7.2% of our total loan portfolio, compared to 8.0% at December 31, 2018.

Changes in the market interest rates we earn on interest-earning assets or pay on interest-bearing liabilities, as well as the volume and types of interest-earning assets, interest-bearing and non-interest-bearing liabilities, are usually the largest drivers of periodic changes in net interest spread, net interest margin and net interest income. In addition, our interest income includes the accretion of the discounts on our acquired loans, which will also affect our net interest spread, net interest margin and net interest income.

The following table s present, for the periods in dicated, information about (i) average balances, the total dollar amount of interest income from interest-earning assets and the resultant average yields; (ii) average balances, the total dollar amount of interest expense on interest-bearing liabilities and the resultant average rates; (iii) net interest income; (iv) the interest rate spread ; and (v) the net interest margin. Yields have been calculated on a pre-tax basis (dollars in t housands).

Increases and decreases in interest income and interest expense result from changes in average balances (volume) of interest-earning assets and interest-bearing liabilities, as well as changes in average interest rates. The following table sets forth the effects of changing rates and volumes on our net interest income during the periods shown. Information is provided wi th respect to (i) effects on interest income attributable to changes in volume (changes in volume multiplied by prior rate) and (ii) effects on interest income attributable to changes in rate (changes in rate multiplied by prior volume). Changes applicable to both volume and rate have been allocated to volume. Yields have been calculated on a pre-tax basis. The table below is a summary of increases and decreases in interest income and interest expense resulting from changes in average balances (volume) and changes in average interest rates (dollars in thousands):

Net interest income for the three months ended September 30, 2019 was $57.8 million compared to $52.6 million during the same period in 2018 , an increase of $5.2 million or 10.0% . I nterest income increased $10.0 million for the three months ended September 30, 2019 compared to the same period in 2018, and was primarily a result of an increase in loans as a result of the Oak Park River Forest acquisition, organic loan and lea se growth, an increase in the securities portfolio , and an increase in average yield on loans and leases . Interest expense increased by $4.7 million for the three months ended September 30, 2019 compared to the same period in 2018 , primarily due to deposits assumed as a result of the Oak Park River Forest acquisition, an increase in FHLB advances to fund organic growth, and increase d interest expense on time deposits and FHLB advances resulting from higher market interest rates .

(1)	Includes loans and leases on non-accrual status.

Net interest income for the nine months ended September 30, 2019 was $162.4 million compared to $125.3 million during the same period in 2018, an increase of $37.0 million or 29.5%. The increase in interest income of $54.8 million was primarily a result of an increase in loans as a result of the acquisitions, organic loan and lease growth, an increase in average yield on loans and leases, and an increase in the securities portfolio. Interest expense increased by $17.8 million for the nine months ended September 30, 2019 compared to the same period in 2018, primarily due to deposits assumed as a result of the acquisitions, increased FHLB advances to fund organic growth, and increased interest cost of interest-bearing deposits and FHLB advances resulting from higher market interest rates.

The net interest margin for the three months ended September 30, 2019 was 4.62%, a decrease of 11 basis points compared to 4.73% for the three months ended September 30, 2018. The primary driver of the decrease for the three month period was increased average interest-bearing deposit costs resulting from increased market interest rates and increased costs of time deposits, partially offset by increases in average loan and lease yields resulting from the acquisitions. The net interest margin for the nine months ended September 30, 2019 was 4.52%, a decrease of four basis points compared to 4.56% for the nine months ended September 30, 2018. The primary driver of the decrease for the nine month period was increased average interest-bearing deposit costs resulting from increased market interest rates and increased costs on FHLB advances, partially offset by increases in average loan and lease yields and loan accretion income resulting from the acquisitions and increased interest rates on variable rate loans. Net loan accretion income was $7.7 million for the three months ended September 30, 2019, compared to $8.3 million for the three months ended September 30, 2018. Net loan accretion income was $17.8 million for the nine months ended September 30, 2019, compared to $14.2 million for the nine months ended September 30, 2018. Total net loan accretion on acquired loans contributed 62 basis points to the net interest margin for the three months ended September 30, 2019, compared to 74 basis points for the three months ended September 30, 2018. Total net loan accretion on acquired loans contributed 50 basis points to the net interest margin for the nine months ended September 30, 2019, compared to 52 basis points for the nine months ended September 30, 2018.

Provision for Loan and Lease Losses

The provision for loan and lease losses represents a charge to earnings necessary to establish an allowance for loan and lease losses that, in management’s evaluation, is appropriate to provide coverage for probable losses incurred in the loan and lease portfolio. The allowance for loan and lease losses is increased by the provision for loan and lease losses and is decreased by charge-offs, net of recoveries on prior charge-offs.

Provisions for loan and lease losses were $5.9 million and $5.8 million for the three months ended September 30, 2019 and 2018, respectively, an increase of $89,000 or 1.5%. Provisions for loan and lease losses were $16.3 million and $14.9 million for the nine months ended September 30, 2019 and 2018, respectively, an increase of $1.4 million or 9.4%. These increases reflect the growth in our loan portfolio, particularly the unguaranteed portion of U.S. government guaranteed loans, the migration of the acquired portfolio into the originated portfolio, and increases to our general reserves. The ALLL as a percentage of loans and leases increased from 0.72% at December 31, 2018 to 0.82% at September 30, 2019.

Non-Interest Income

Non-interest income was $14.8 million for the three months ended September 30, 2019, compared to $10.9 million for the three months ended September 30, 2018, an increase of $3.9 million or 35.8%. The increase was primarily due to an increase in net gains on sales of U.S. government guaranteed loans due to increased sales volume during the quarter, and a reduction in loan servicing asset revaluation due to changes in fair value of the servicing asset as a result of changes in prepayment speeds.

Non-interest income was $41.0 million for the nine months ended September 30, 2019, compared to $36.2 million for the nine months ended September 30, 2018, an increase of $4.7 million or 13.1%. The increase was primarily due to a reduction in loan servicing asset revaluation due to changes in fair value of the servicing asset as a result of changes to valuation assumptions, security sales during the period, an increase in the fair value of equity securities, net, wealth management and trust income as a result of the First Evanston acquisition, and an increase in net gains on sales of U.S. government guaranteed loans primarily due to increased average premiums during the period.

Fees and service charges on deposits represent amounts charged to customers for banking services, such as fees on deposit accounts, and include, but are not limited to, maintenance fees, insufficient fund fees, overdraft protection fees, wire transfer fees and other charges. Fees and service charges on deposits were $1.6 million for the three months ended September 30, 2019, compared to $1.8 million for the three months ended September 30, 2018, a decrease of $213,000 or 11.7%. The variance was primarily attributable to lower fee income from business and consumer accounts. Fees and service charges on deposits were $4.8 million for the nine months ended September 30, 2019, compared to $4.6 million for the nine months ended September 30, 2018, an increase of $230,000 or 5.0%. The increase was primarily driven by additional deposit accounts from the First Evanston acquisition.

While portions of the loans that we origin ate are sold and generate gain s on sale revenue, servicing rights for the majority of loans that we sell are retained by us . In exchange for continuing to service loans that have been sold, we receive servicing revenue from a portion of the interest cash flow of the loan. We generated $2.7 million in loan servicing revenue on the sold portion of the U.S. government guaranteed loans for the three months ended September 30, 2019 , compared to $2.6 million for the three months ended September 30, 2018 , an increase of $70,000 or 2.7% . We generated $7.9 million in loan servicing revenue for the nine months ended September 30, 2019 , compared to $7.6 million for the nine months ended September 30, 2018 , an increase of $256,000 or 3.4% . The in crease s were primarily driven by a n increase in total loans serviced due to additional U.S government guaranteed loans sold with retained servicing rights during the periods . At September 30, 2019 and December 31, 2018 , the outstanding balance o f guaranteed loans serv iced was $1.3 billion.

Loan servicing asset revaluation represents net changes in the fair value of our servicing assets. Loan servicing asset revaluation had a downward adjustment of $1.6 million for the three months ended September 30, 2019, compared to $2.4 million for the three months ended September 30, 2018, a decrease of $836,000 or 34.2% due to improved secondary market premiums. Loan servicing asset revaluation had a downward adjustment of $4.1 million for the nine months ended September 30, 2019, compared to $6.4 million for the nine months ended September 30, 2018, a decrease of $2.3 million or 36.1%. The reductions in loan servicing asset revaluation were primarily driven by the change in secondary market premiums.

ATM and interchange fees were $973,000 for the three months ended September 30, 2019, compared to $1.5 million for the three months ended September 30, 2018, a decrease of $567,000 or 36.8%. ATM and interchange fees were $2.6 million for the nine months ended September 30, 2019, compared to $3.3 million for the nine months ended September 30, 2018, a decrease of $668,000 or 20.2%. The decreases were primarily driven by lower interchange income and decreased transactional account volume. In addition, the nine months ended September 30, 2018 included a credit card vendor agreement signing bonus.

Net gains on sales of securities were $178,000 during the three months ended September 30, 2019. There were no security sales during the three months ended September 30, 2018. Net gains on sales of securities were $1.2 million during the nine months ended September 30, 2019, compared to $4,000 for the nine months ended September 30, 2018. The increase is a result of sales during the period. We sold $32.5 million of securities during the three months ended September 30, 2019 and sold no securities during the three months ended September 30, 2018. We sold $92.1 million of securities during the nine months ended September 30, 2019, compared to $544,000 during the nine months ended September 30, 2018.

Change in fair value of equity securities, net, was a $15,000 decrease and $1.0 million increase in fair value for the three and nine months ended September 30, 2019, respectively. Upon adoption of new accounting guidance as of January 1, 2019, changes in fair value of equity securities are recorded through net income rather than other comprehensive income. The amount recorded during the periods is a result of the increase or decrease in the fair value of these securities.

Net gains on sales of loans were $9.4 million for the three months ended September 30, 2019, compared to $5.0 million for the three months ended September 30, 2018, an increase of $4.4 million or 87.5%. We sold $93.3 million of U.S. government guaranteed loans during the three months ended September 30, 2019 compared to $59.6 million during the three months ended September 30, 2018. Net gains on sales of loans were $23.1 million for the nine months ended September 30, 2019, compared to $22.2 million for the nine months ended September 30, 2018, an increase of $896,000 or 4.0%. We sold $234.7 million of U.S. government guaranteed loans during the nine months ended September 30, 2019, compared to $233.1 million during the nine months ended September 30, 2018. The increases in net gains on sales were primarily driven by increased government guaranteed loan sales volume and increased average premiums during the periods.

Wealth management and trust income represents fees charged to customers for investment, trust, or wealth management services and are primarily determined by total assets under management. Wealth management and trust income was $653,000 for the three months ended September 30, 2019, compared to $674,000 for the three months ended September 30, 2018. Wealth management and trust income was $1.9 million for the nine months ended September 30, 2019, compared to $866,000 for the nine months ended September 30, 2018. Prior to the First Evanston acquisition during the second quarter of 2018, we did not record wealth management and trust income. Assets under management were $566.0 million and $648.5 million as of September 30, 2019 and 2018, respectively. The decrease was primarily driven by market conditions and account closures.

Other non-interest income was $918,000 for the three months ended September 30, 2019 , compared to $1.7 million for the three months ended September 30, 2018 , a decrease of $754,000 or 45.1% . The primary drivers of th e decrease were a decrease in gains on sales of assets held for sale of $ 677, 000 and a decrease in customer derivative products fee income of $258,000 due to the current interest rate environment .

Other non-interest income was $2.6 million for the nine months ended September 30, 2019, compared to $4.1 million for the nine months ended September 30, 2018, a decrease of $1.5 million or 36.4%. The primary drivers of the decrease were a decrease in customer derivative products fee income of $912,000 due to the interest rate environment, and loss on sales of assets held for sale of $29,000 for the nine months ended September 30, 2019, compared to a gain of $908,000 for the nine months ended September 30, 2018.

Non-Interest Expense

Non-interest expense was $45.4 million for the three months ended September 30, 2019, compared to $37.7 million for the three months ended September 30, 2018, an increase of $7.7 million or 20.5%. Non-interest expense was $130.1 million for the nine months ended September 30, 2019, compared to $114.8 million for the nine months ended September 30, 2018, an increase of $15.3 million or 13.3%. The increases were primarily due to the additional expenses as a result of our acquisition related activity, including salary and employee benefits, system conversion expenses, other intangible asset amortization expense, and the core system conversion completed in the first quarter of 2019.

The following table presents the major components of our non-interest expense for the periods indicated (dollars in thousands):

The increases were primarily a result of the acquisitions. Our staffing increased from 924 full-time equivalent employees as of September 30, 2018 to 1,004 as of September 30, 2019.

Occupancy expense was $3.7 million for the three months ended September 30, 2019, compared to $3.5 million for the three months ended September 30, 2018, an increase of $197,000 or 5.6%. Occupancy expense was $12.4 million for the nine months ended September 30, 2019, compared to $11.8 million for the nine months ended September 30, 2018, an increase of $560,000 or 4.7%. The increases were primarily a result of our additional branches resulting from the acquisitions and seasonal weather fluctuations in the Chicagoland area, offset by the consolidation of seven branches and two other facilities.

Equipment expense was $767,000 for the three months ended September 30, 2019 , compared to $617,000 for the three months ended September 30, 2018 , an increase of $150,000 or 24.3% . Equipment expense was $2.2 million for the nine months ended September 30, 2019 , compared to $1.8 million for the nine months ended Se ptember 30, 2018 , an increase of $390,000 or 21.9% . The increase s were primarily a result of increased investment in equipment and technology assets.

Loan and lease related expenses were $1.9 million for the three months ended September 30, 2019, compared to $1.0 million for the three months ended September 30, 2018, an increase of $934,000 or 92.0%. Loan and lease related expenses were $5.4 million for the nine months ended September 30, 2019, compared to $3.9 million for the nine months ended September 30, 2018, an increase of $1.5 million or 38.1%. The increases were primarily driven by additional loans and leases from organic growth and increased collection expense.

Legal, audit and other professional fees were $4.1 million for the three months ended September 30, 2019, compared to $2.4 million for the three months ended September 30, 2018, an increase of $1.7 million or 72.4%. The increase was primarily driven by higher professional services costs. Legal, audit and other professional fees were $9.1 million for the nine months ended September 30, 2019, compared to $8.6 million for the nine months ended September 30, 2018, an increase of $486,000 or 5.6%. The increase was primarily driven by our core system conversion and the Oak Park River Forest acquisition, partially offset by the higher expenses related to the First Evanston acquisition incurred in 2018.

Data processing expense was $4.1 million for the three months ended September 30, 2019, compared to $2.7 million for the three months ended September 30, 2018, an increase of $1.3 million or 49.1%. The increase was primarily due to increased expenses in connection with the Oak Park River Forest core system conversion. Data processing expense was $11.1 million for the nine months ended September 30, 2019, compared to $15.4 million for the nine months ended September 30, 2018, a decrease of $4.3 million or 28.2%. The decrease was primarily due to contract termination expenses during the second quarter of 2018 related to our core system conversion, which was completed during the first quarter of 2019.

Net loss recognized on other real estate owned and other related expenses was $95,000 for the three months ended September 30, 2019, compared to a net gain of $284,000 for the three months ended September 30, 2018, an increase in expense of $379,000 or 133.5%. This variance was primarily attributed to a net gain on sales of other real estate owned assets during the third quarter of 2018 of $489,000 compared to $38,000 during the three months ended September 30, 2019, and increased expenses due to higher real estate tax expenses. Net loss recognized on other real estate owned and other related expenses was $543,000 for the nine months ended September 30, 2019, compared to $187,000 for the nine months ended September 30, 2018, an increase of $356,000 or 190.4%. This variance was primarily attributed to decreased gains on sales of other real estate owned assets.

Regulatory assessments were $228,000 for the three months ended September 30, 2019, compared to $675,000 for the three months ended September 30, 2018, a decrease of $447,000 or 66.2%. The decrease was primarily driven by our FDIC small business assessment credit. Regulatory assessments were $540,000 for the nine months ended September 30, 2019, compared to $1.3 million for the nine months ended September 30, 2018, a decrease of $742,000 or 57.9%. The decrease was primarily driven by an FDIC credit and updated FICO multiplier.

Other intangible assets amortization expense was $2.0 million for the three months ended September 30, 2019, compared to $1.9 million for the three months ended September 30, 2018, an increase of $105,000 or 5.5%. Other intangible assets amortization expense was $5.7 million for the nine months ended September 30, 2019, compared to $3.8 million for the nine months ended September 30, 2018, an increase of $1.9 million or 51.1%. The increases were attributed to additional core deposit intangible asset amortization resulting from the acquisitions and a customer relationship intangible asset amortization as a result of the First Evanston acquisition.

Advertising and promotions were $843,000 for the three months ended September 30, 2019, compared to $537,000 for the three months ended September 30, 2018, an increase of $306,000 or 57.0%. Advertising and promotions were $2.3 million for the nine months ended September 30, 2019, compared to $1.1 million for the nine months ended September 30, 2018, an increase of $1.2 million or 101.6%. The increases were primarily due to an increase in advertising attributable to deposit advertising campaigns and an increase in sponsorships.

Telecommunications expense was $474,000 for the three months ended September 30, 2019 , compared to $435,000 for the three months ended September 30, 2018 , an increase of $39,000 or 9.0% . Telecommunications expense was $1.5 million for the nine months ended September 30, 2019 , compared to $1.3 million for the nine months ended September 30, 2018 , an increase of $156,000 or 11.8% . Th e increase s were primarily a result of our larger branch network and integration expenses partially offset by cost savings initiatives .

Other non-interest expense was $2.7 million for the three months ended September 30, 2019, compared to $2.9 million for the three months ended September 30, 2018, a decrease of $201,000 or 7.0%. The primary drivers of the decrease were decreases of $360,000 in provision for unfunded commitments due to a decrease in our unfunded loan commitments, $123,000 in ATM, debit card, and other losses, and $73,000 in impairment charges on assets held for sale.

Other non-interest expense was $8.4 million for the nine months ended September 30, 2019, compared to $6.8 million for the nine months ended September 30, 2018, an increase of $1.6 million or 23.5%. The primary drivers of the increase were increases of $915,000 in stationery, supplies and postage, $482,000 in ATM, debit card, and other losses, and $203,000 in impairment charges on assets held for sale.

Our efficiency ratio was 59.81% for the three months ended September 30, 2019, compared to 56.41% for the three months ended September 30, 2018. The change in our efficiency ratio for the three months ended September 30, 2019 is primarily attributable to increased non-interest expense driven by the Oak Park River Forest acquisition, partially offset by the increase in our net interest income resulting from the acquisition and organic loan and lease growth. Our efficiency ratio was 61.15% for the nine months ended September 30, 2019, compared to 68.70% for the nine months ended September 30, 2018. The improvement in our efficiency ratio for the nine months ended September 30, 2019 is primarily attributable to the increase in our net interest income resulting from our acquisitions and organic loan and lease growth, partially offset by increased non-interest expense primarily driven by increased salary and employee benefit expenses and core system conversion expenses. Our adjusted efficiency ratio was 58.17% for the three months ended September 30, 2019, compared to 55.62% for the three months ended September 30, 2018. Our adjusted efficiency ratio was 57.87% for the nine months ended September 30, 2019, compared to 61.73% for the nine months ended September 30, 2018. Please refer to the “Reconciliation of Non-GAAP Financial Measures” for a reconciliation of our non-GAAP measures to the most directly comparable GAAP financial measure.

Income Taxes

Our provision for income taxes for the three months ended September 30, 2019 totaled $5.9 million, compared to $5.4 million for the three months ended September 30, 2018. The increase in income tax expense was primarily due to increased income before provision for income taxes during the period. Our effective tax rate was 27.9% for the three months ended September 30, 2019 and 27.1% for the three months ended September 30, 2018. The Company recorded minimal discrete income tax expense related to the exercise of stock options and vesting of restricted stock for the three months ended September 30, 2019, and recorded discrete income tax benefit of $151,000 for the three months ended September 30, 2018.

Our provision for income taxes for the nine months ended September 30, 2019 totaled $15.8 million, compared to $7.8 million for the nine months ended September 30, 2018. The increase in income tax expense was primarily due to increased income before provision for income taxes during the period. Our effective tax rate was 27.7% and 24.4% for the nine months ended September 30, 2019 and 2018, respectively. The Company recorded discrete income tax benefit related to the exercise of stock options and vesting of restricted stock of $64,000 and $362,000 for the nine months ended September 30, 2019 and 2018, respectively. We expect our effective tax rate for 2019 to be approximately 27% to 29%.

The Tax Cuts and Jobs Act (the “Tax Act”) was enacted on December 22, 2017, and ASC Topic 740, Income Taxes (“ASC 740”), required us to reflect the changes associated with the Tax Act’s provisions in the fourth quarter of 2017. The Tax Act is complex and has extensive implications for our federal and state taxes. Among other things, the Tax Act reduced the corporate federal income tax rate from 35% to 21%, effective January 1, 2018. Also on December 22, 2017, the SEC issued Staff Accounting Bulletin No. 118, which provides guidance on accounting for the Tax Act’s impact. SAB 118 provides a measurement period, not to extend beyond one year from the date of enactment. As a result of the rate change, our net deferred tax assets were required to be revalued during the period in which the new legislation was enacted. We recorded net income tax expense of $7.2 million during the fourth quarter of 2017 as a result of this change, and recorded an additional discrete income tax benefit of $760,000 during the first quarter of 2018.

Financial Condition

Balance Sheet Analysis

Our total assets increased by $495.7 million, or 10.0%, to $5.4 billion at September 30, 2019, compared to $4.9 billion at December 31, 2018. The increase in total assets includes an increase of $329.5 million, or 9.4%, in loans and leases from $3.5 billion at December 31, 2018 to $3.8 billion at September 30, 2019. Our originated loan and lease portfolio increased by $533.7 million and our acquired loan and lease portfolio decreased by $204.2 million. The increase in our originated portfolio is primarily attributed to organic loan and lease growth and renewals of acquired non-impaired loans that are now reflected with originated loans. The decrease in our acquired portfolio is attributed to renewals reflected in originated loans, payoffs, and pay downs during the period, partially offset by the Oak Park River Forest acquisition.

Total liabilities increased by $410.5 million, or 9.6%, to $4.7 billion at September 30, 2019, compared to $4.3 billion at December 31, 2018. The increase is a result of an increase in total deposits of $330.4 million, or 8.8%, primarily attributed to the Oak Park River Forest acquisition, time deposit growth as a result of deposit promotions to seek to expand our retail customer base, money market growth, and in increase in Federal Home Loan Bank advances due to loan and lease growth and security purchases.

Investment Portfolio

Our investment securities portfolio consists of securities classified as available-for-sale and held-to-maturity. There were no securities classified as trading in our investment portfolio as of September 30, 2019 or December 31, 2018. All available-for sale securities are carried at fair value and may be used for liquidity purposes should management consider it to be in our best interest. Securities available-for-sale consist primarily of residential mortgage-backed securities, commercial mortgage- backed securities and U.S. government agencies securities.

Securities available-for-sale increased $214.3 million, or 26.2%, from $817.7 million at December 31, 2018 to $1.0 billion at September 30, 2019. The increase was primarily attributed to securities purchases and the adoption of the provisions of ASU No. 2017-12 during the year. Upon adoption, we elected to reclassify $94.8 million of securities held-to-maturity to securities available-for-sale. Additionally, we acquired $30.3 million of available-for-sale securities upon the acquisition of Oak Park River Forest, and there were additional purchases of agency, mortgage-backed, corporate, and U.S. Treasury securities during the year.

At September 30, 2019, our held-to-maturity securities portfolio consists of obligations of states, municipalities and political subdivisions. We carry these securities at amortized cost. Securities held-to-maturity decreased $94.8 million, or 95.6%, from $99.3 million at December 31, 2018 to $4.4 million at September 30, 2019. This decrease was due to the adoption of ASU No. 2017-12 as discussed above.

The fair value of our equity and other securities portfolio was $7.6 million at September 30, 2019. We adopted the provisions of ASU No 2016-01 on January 1, 2019, which require changes in the value of certain equity securities and mutual fund investments to be recognized in the Consolidated Statements of Operations. These securities were included in the available-for-sale portfolio as of December 31, 2018.

We had no securities that were classified as having other-than-temporary-impairment (“OTTI”) as of September 30, 2019 or December 31, 2018.

The following table summarizes the fair value of the available-for-sale and held-to-maturity securities portfolio as of the dates presented (dolla rs in thousands):

Certain securities have fair values less than amortized cost and, therefore, contain unrealized losses. At September 30, 2019, we evaluated the securities which had an unrealized loss for OTTI and determined all declines in value to be temporary. There were 74 investment securities with unrealized losses at September 30, 2019. We anticipate full recovery of amortized cost with respect to these securities by maturity, or sooner in the event of a more favorable market interest rate environment. We do not intend to sell these securities and it is not more likely than not that we will be required to sell them before recovery of their amortized cost basis, which may be at maturity.

The following tables (dollars in thousands) set forth certain information regarding contractual maturities and the weighted average yields of our investment securities as of the dates presented. Expected maturities may differ from contractual maturities if borrowers have the right to call or prepay obligations with or without call or prepayment penalties.

Restricted Stock

As a member of the Federal Home Loan Bank system, Byline Bank is required to maintain an investment in the capital stock of the FHLB. No market exists for this stock, and it has no quoted market value. The stock is redeemable at par by the FHLB and is, therefore, carried at cost. In addition, Byline Bank owns stock of Bankers’ Bank that was acquired as part of the Ridgestone acquisition. The stock is redeemable at par and carried at cost. As of September 30, 2019 and December 31, 2018, we held $24.3 million and $19.2 million, respectively, in FHLB and Bankers’ Bank stock. We evaluate impairment of our investment in FHLB and Bankers’ Bank based on the ultimate recoverability of the par value rather than by recognizing temporary declines in value. We did not identify any indicators of impairment of FHLB and Bankers’ Bank stock as of September 30, 2019 and December 31, 2018.

Loan and Lease Portfolio

Lending-related income is the most important component of our net interest income and is the main driver of the results of our operations. Total loans and leases at September 30, 2019 and December 31, 2018 were $3.8 billion and $3.5 billion, respectively, an increase of $329.5 million, or 9.4%. Originated loans were $2.8 billion at September 30, 2019, an increase of $533.7 million or 23.8%, compared to $2.2 billion at December 31, 2018. Acquired impaired loans and acquired non-impaired loans and leases were $1.0 billion at September 30, 2019, a decrease of $204.2 million or 16.2%, compared to $1.3 billion at December 31, 2018. The growth in the originated loan and lease portfolio was primarily driven by increases in commercial and industrial loans and leases. The decrease in the acquired loan and lease portfolio was driven by renewals that are reflected within originated loans, payoffs, and maturities during the period, partially offset by loans acquired as a result of the Oak Park River Forest acquisition.

W e strive to maintain a relatively diversified loan portfolio to help reduce the risk inherent in concentration in certain types of collateral.

At September 30, 2019 , 47.7% of the loan and lease portfolio bears interest at fixed rates and 52.3% at floating rates. The expected life of our loan portfolio will differ from contractual maturities because borrowers may have the right to curtail or prepay their loans with or without penalties. Because a portion of the portfolio is accounted for under A SC 310-30, the carrying value is significantly affected by estimates and it is impracticable to allocate scheduled payments for those loans based on those estimates. Consequently, the tables presented include information limited to contractual maturities o f the underlying loans.

Allowance for Loan and Lease Losses

The ALLL is determined by us on a quarterly basis, although we are engaged in monitoring the appropriate level of the allowance on a more frequent basis. The ALLL reflects management’s estimate of probable incurred credit losses inherent in the loan and lease portfolios. The computation includes elements of judgement and high levels of subjectivity.

Factors considered by us include, but are not limited to, actual loss experience, peer loss experience, changes in size and risk profile of the portfolio, identification of individual problem loan and lease situations which may affect a borrower’s ability to repay, and evaluation of the prevailing economic conditions. Changes in conditions may necessitate revision of the estimate in future periods.

We assess the ALLL based on three categories: (i) originated loans and leases, (ii) acquired non-impaired loans and leases, and (iii) acquired impaired loans with further credit deterioration after the acquisitions or our recapitalization.

Total ALLL was $31.6 million at September 30, 2019 compared to $25.2 million at December 31, 2018, an increase of $6.4 million, or 25.3%. The increase was primarily due to increases in the general reserve driven by newly originated loans and leases and renewals of acquired non-impaired loans that are also reflected within originated loans and leases, and specific impairments in the unguaranteed portion of the U.S. government guaranteed portfolio as well as a commercial loan relationship.

Total ALLL to total loans and leases held for investment, net before ALLL, was 0.82% and 0.72% of total loans and leases at September 30, 2019 and December 31, 2018, respectively. The increase was primarily driven by an increase in the general reserve resulting from originated loan and lease growth and an increase in specific impairments in the unguaranteed portion of the U.S. government guaranteed portfolio. We valued significant amounts of acquired loans at fair value at acquisition date as a result of our recapitalization, the Ridgestone acquisition, the First Evanston acquisition, and the Oak Park River Forest acquisition. As a result of marking these acquired loans to fair value, management believes that this reduces the need to reserve for these loans for a period after acquisition, in accordance with applicable accounting guidance. Acquisition accounting adjustments remaining on loans from our recapitalization, the Ridgestone acquisition, the First Evanston acquisition, and the Oak Park River Forest acquisition totaled $31.1 million and $34.0 million at September 30, 2019 and December 31, 2018, respectively.

Non-Performing Assets

Non-performing loans and leases include loans and leases 90 days past due and still accruing, loans and leases accounted for on a non-accrual basis and accruing restructured loans. Non-performing assets consist of non-performing loans and leases plus other real estate owned. Non-performing assets at September 30, 2019 and December 31, 2018 totaled $50.3 million and $33.0 million, respectively, an increase of $17.3 million, or 52.5%. The increase was primarily driven by downgrades in the U.S. government guaranteed loan portfolio and a commercial relationship. Non-performing assets consisted of $6.2 million and $4.6 million of U.S. government guaranteed balances at September 30, 2019 and December 31, 2018, respectively.

Total non-accrual loans and leases increased by $13.7 million, or 53.0%, between December 31, 2018 and September 30, 2019 due to additional non-accrual loans primarily from the downgrades of U.S. government guaranteed loans and a commercial relationship. The U.S. government guaranteed portion of non-performing loans totaled $4.2 million at September 30, 2019 and $4.6 million at December 31, 2018.

Total accruing loans past due slightly decreased from $24.5 million at December 31, 2018 to $24.2 million at September 30, 2019. This represents a decrease $261,000, or 1.1%, and can be attributed to decreases in residential real estate and installment and other loans, partially offset by increases in commercial and industrial loans, primarily in the 30-59 days past due category. See Note 6 of our Unaudited Interim Condensed Consolidated Financial Statements, included in this report, for further information.

Total OREO increased from $5.3 million at December 31, 2018 to $8.5 million at September 30, 2019. The $3.2 million increase in OREO resulted primarily from net additions of $2.2 million to OREO as a result of the Oak Park River Forest acquisition, and loan foreclosures and deeds in lieu of loan foreclosures totaling $3.9 million, partially offset by dispositions of $2.7 million, and valuation adjustments of $189,000. The government guaranteed portion of OREO was $2.0 million at September 30, 2019. There was no government guaranteed portion of OREO at December 31, 2018.

The following table sets forth the amounts of non-performing loans and leases, non-performing assets, and OREO at the dates indicated (dollars in thousands):

(1)	Includes $9.2 million and $7.3 million of non-accrual restructured loans at September 30, 2019 and December 31, 2018.

(2)	For the nine months ended September 30, 2019, $1.9 million in interest income would have been recorded had non-accrual loans been current.

(3)	For the nine months ended September 30, 2019, $391,000 in interest income would have been recorded had troubled debt restructurings included within non-accrual loans been current.

Acquired impaired loans (accounted for under ASC 310-30) that are delinquent and/or on non-accrual status continue to accrue income provided the respective pool in which those assets reside maintains a discount and recognizes accretion income. The aforementioned loans are characterized as performing loans based on contractual delinquency. If the pool no longer has a discount and accretion income can no longer be recognized, any loan within that pool on non-accrual status will be classified as non-accrual for presentation purposes.

Deposits

We gather deposits primarily through each of our 60 branch locations in the Chicago metropolitan area and one branch in Brookfield, Wisconsin. Through our branch network, online, mobile and direct banking channels, we offer a variety of deposit products including demand deposit accounts, interest-bearing products, savings accounts, and certificates of deposit. We offer competitive online, mobile and direct banking channels. Small businesses are a significant source of low cost deposits as they value convenience, flexibility and access to local decision makers that are responsive to their needs. Deposits assumed from the Oak Park River Forest and First Evanston acquisitions were recorded at fair value using the acquisition method of accounting in accordance with ASC Topic 805.

Total deposits at September 30, 2019 were $4.1 billion, representing a n increase of $330.4 m illion, or 8.8% , compared to $3.7 billion at December 31, 2018 . Non-interest- bearing deposits were $1.2 b illion , or 29.9 % of total deposits, at September 30, 2019 , an increase of $28.6 million , or 2.4% , compared to $1.2 b illion at December 31, 2018 , or 31.8 % of total deposits. Core deposits were 81.1 % and 81.7% of total deposits at September 30, 2019 and December 31, 2018 , respectively .

The increase in time deposits was driven by promotional campaigns during the first and second quarters of 2019. Our average cost of deposits was 94 basis points during the third quarter of 2019 compared to 64 basis points during the third quarter of 2018. This increase was primarily attributed to higher rates on interest-bearing deposits as a result of local competition and the interest rate environment. We had $81.0 million and $50.0 million of brokered time deposits at September 30, 2019 and December 31, 2018, respectively.

Borrowed Funds

In addition to deposits, we also utilize FHLB advances as a supplementary funding source to finance our operations. The bank’s advances from the FHLB are collateralized by residential and multi-family real estate loans and securities. At September 30, 2019 and December 31, 2018, we had maximum borrowing capacity from the FHLB of $1.9 billion and $1.7 billion, respectively, subject to the availability of collateral. During the nine months ended September 30, 2019, outstanding FHLB advances increased to $506.0 million, from $425.0 million at December 31, 2018, resulting from asset growth.

We amended the credit agreement, which extended the maturity date to October, 2020. The amended revolving line of credit bears interest at either the LIBOR Rate plus 195 basis points or the Prime Rate minus 75 basis points, based on our election, which is required to be communicate to the lender at least three business days prior to the commencement of an interest period. If we fail to provide timely notification, the interest rate will be Prime Rate minus 75 basis points.

At September 30, 2019, FHLB advances have maturities ranging from October 2019 to December 2019.

Customer Repurchase Agreements (Sweeps)

Securities sold under agreements to repurchase represent a demand deposit product offered to customers that sweep balances in excess of the FDIC insurance limit into overnight repurchase agreements. We pledge securities as collateral for the repurchase agreements. Securities sold under agreements to repurchase decreased by $1.9 million, from $34.2 million at December 31, 2018 to $32.3 million at September 30, 2019.

Liquidity

We manage liquidity based upon factors that include the amount of core deposits as a percentage of total deposits, the level of diversification of our funding sources, the amount of non-deposit funding used to fund assets, the availability of unused funding sources, off-balance sheet obligations, the availability of assets to be readily converted into cash without undue loss, the amount of cash and liquid securities we hold and the re-pricing characteristics and maturities of our assets when compared to the re-pricing characteristics of our liabilities, the ability to securitize and sell certain pools of assets and other factors.

Our liquidity needs are primarily met by cash and investment securities positions, growth in deposits, cash flow from amortizing loan portfolios, and borrowings from the FHLB. For additional information regarding our operating, investing, and financing cash flows, see Consolidated Statements of Cash Flows in our Unaudited Interim Condensed Consolidated Financial Statements included elsewhere in this report.

As of September 30, 2019 , Byline Bank had maximum borrowing capacity from the FHLB of $ 1. 9 b illion and $ 419.1 million from the Federal Reserve Bank (“FRB”) . As of September 30, 2019 , Byline Bank had open advances of $506.0 million and open letters of credit of $ 20.8 million , leaving us with available aggregate borrowing capacity of $ 1.4 b illion. In addition, Byline Bank had uncommitted federal fun ds lines available of $105 .0 million.

As of December 31, 2018, Byline Bank had maximum borrowing capacity from the FHLB of $1.7 billion and $293.6 million from the FRB. As of December 31, 2018, Byline Bank had open advances of $425.0 million and open letters of credit of $32.6 million, leaving us with available aggregate borrowing capacity of $1.3 billion. In addition, Byline Bank had an uncommitted federal funds line available of $55.0 million.

On October 13, 2016, we entered into a $30.0 million revolving credit agreement with a correspondent bank. In April 2017, the revolving line of credit was amended to a non-revolving line of credit as long as the outstanding balance exceeds $5.0 million. When the outstanding balance was reduced to $5.0 million, the line of credit was converted to a revolving line of credit with credit availability up to $5.0 million until maturity. In July 2017, we repaid the outstanding balance, in full, under this line of credit of $16.2 million with proceeds from our initial public offering. On October 10, 2019, the Company entered into a fourth amendment to the revolving credit agreement, which increased the revolving loan commitment to $15.0 million and extended the maturity of the credit facility to October 9, 2020. As of September 30, 2019, no balance was outstanding on the line of credit.

On April 30, 2019, we drew on the line of credit for $5.7 million and selected the LIBOR plus 225 basis points interest rate option, which was the interest rate option at the time of the draw. The funds were utilized to repay a line of credit assumed as a result of the Oak Park River Forest acquisition. We repaid the $5.7 million outstanding balance of the line of credit in full on May 31, 2019.

There are regulatory limitations that affect the ability of Byline Bank to pay dividends to the Company. See Note 21 of our Consolidated Financial Statements, included in our Annual Report on Form 10-K for the year ended December 31, 2018 for additional information. Management believes that such limitations will not impact our ability to meet our ongoing short-term cash obligations.

We expect that our cash and liquidity resources will be generated by the operations of Byline Bank, which we expect to be sufficient to satisfy our liquidity and capital requirements for at least the next twelve months.

Capital Resources

Stockholders’ equity at September 30, 2019 was $735.9 million compared to $650.7 million at December 31, 2018, an increase of $85.2 million, or 13.1%. The increase was primarily driven by the acquisition of Oak Park River Forest, the issuance of common stock upon the exercise of stock options, retained earnings, and a decrease to other comprehensive loss.

The Company and Byline Bank are subject to various regulatory capital requirements administered by federal banking regulators. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by federal banking regulators that, if undertaken, could have a direct material effect on our financial statements.

Under applicable bank regulatory capital requirements, each of the Company and Byline Bank must meet specific capital guidelines that involve quantitative measures of their assets, liabilities and certain off-balance sheet items as calculated under regulatory accounting practices. Byline Bank must also meet certain specific capital guidelines under the prompt corrective action framework. The capital amounts and classification are subject to qualitative judgments by the federal banking regulators about components, risk weightings and other factors. Quantitative measures established by regulation to ensure capital adequacy require the Company and Byline Bank to maintain minimum amounts and ratios of CET1 Capital, Tier 1 capital and total capital to risk-weighted assets and of Tier 1 capital to average consolidated assets, (referred to as the “leverage ratio”), as defined under these capital requirements.

As of September 30, 2019, Byline Bank exceeded all applicable regulatory capital requirements and was considered “well-capitalized.” There have been no conditions or events since September 30, 2019 that management believes have changed Byline Bank’s classifications.

The regulatory capital ratios for the Company and Byline Bank to meet the minimum capital adequacy standards and for Byline Bank to be considered well capitalized under the prompt corrective action framework and the Company’s and Byline Bank’s actual capital amounts and ratios are set forth in the following tables as of the periods indicated (dollars in thousands):

The Company and Byline Bank must maintain a capital conservation buffer consisting of CET1 capital greater than 2.5% of risk-weighted assets above the required minimum risk-based capital levels in order to avoid limitations on paying dividends, repurchasing shares, and paying discretionary bonuses. The conservation buffers for the Company and Byline Bank exceed the minimum capital requirement as of September 30, 2019.

Provisions of state and federal banking regulations may limit, by statute, the amount of dividends that may be paid to the Company by Byline Bank without prior approval of Byline Bank’s regulatory agencies. The Company is economically dependent on the cash dividends received from Byline Bank. These dividends represent the primary cash flow from operating activities used to service obligations. For the nine months ended September 30, 2019 and year ended December 31, 2018, the Company received $8.0 million and $2.9 million, respectively, in cash dividends from Byline Bank in order to pay the required interest on its outstanding junior subordinated debentures in connection with its trust preferred securities interest, dividends on the Series B preferred stock outstanding, and to fund other Company-related activities.

On November 1, 2019, the Company announced that its Board of Directors approved a stock repurchase program authorizing the purchase of up to an a ggregate of 1,250,000 shares of the Company’s outstanding common stock. The shares may, at the discretion of management, be repurchased from time to time in open market purchases as market conditions warrant or in privately negotiated transactions, includi ng pursuant to a Rule 10b5-1 plan, all as effected to the extent permitted by applicable law, including pursuant to the safe harbor provided under Rule 10b-18 of the Securities Exchange Act of 1934, as amended. The Company is not obligated to purchase any shares under the program, and the program may be discontinued at any time. The actual timing, number and share price of shares purchased under the repurchase program will be determined by the Company at its discretion and will depend on a number of factors , including the market price of the Company’s stock, general market and economic conditions and applicable legal requirements. The shares authorized to be repurchased represent approximately 3.3% of the Company’s currently outstanding common stock. Shares repurchased, if any, would be available for issuance under the Company’s equity incentive plans and for other general corporate purposes.

Contractual Obligations

FHLB advances are fully described in Note 12 of our Unaudited Interim Condensed Consolidated Financial Statements, included elsewhere in this report. Operating lease obligations are in place for facilities and land on which banking facilities are located. See Note 15 of our Unaudited Interim Condensed Consolidated Financial Statements, included elsewhere in this report for additional information.

Off-Balance Sheet Items and Other Financing Arrangements

We are a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of our customers. These financial instruments include commitments to extend credit, commercial letters of credit and standby letters of credit. Those instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the Consolidated Statements of Financial Condition. The contractual or notional amounts of those instruments reflect the extent of involvement we have in particular classes of financial instruments.

Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amount does not necessarily represent future cash requirements. We evaluate each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by Byline Bank upon extension of credit, is based on management’s credit evaluation of the counterparty. Collateral is primarily obtained in the form of commercial and residential real estate (including income producing commercial properties).

Letters of credit are conditional commitments issued by Byline Bank to guarantee the performance of a customer to a third-party. Those guarantees are primarily issued to support public and private borrowing arrangements, bond financing and similar transactions. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers.

Our exposure to credit loss in the event of non-performance by the other party to the financial instrument for commitments to extend credit and standby letters of credit is represented by the contractual or notional amount of those instruments. We use the same credit policies in making commitments and conditional obligations as for funded instruments. We do not anticipate any material losses as a result of the commitments and standby letters of credit.

We enter into interest rate swaps that are used to manage differences in the amount, timing, and duration of our known or expected cash receipts and its known or expected cash payments principally related to certain variable rate borrowings. We also enter into interest rate swaps with certain qualified borrowers to facilitate the borrowers’ risk management strategies and concurrently entered into mirror-image derivatives with a third party counterparty.

We recognize derivative financial instruments at fair value regardless of the purpose or intent for holding the instrumen t. We record derivative assets and derivative liabilities on the Consolidated Statements of Financial Condition within other assets and other liabilities, respectively. Because the derivative assets and liabilities recorded on the balance sheet at Septembe r 30, 2019 do not represent the amounts that may ultimately be paid under these contracts, these assets and liabilities are listed in the table below (dollars in thousands):

GAAP Reconciliation and Management Explanation of Non-GAAP Financial Measures

Some of the financial measures included in our “Selected Financial Data” are not measures of financial performance in accordance with GAAP. Our management uses the non‑GAAP financial measures set forth below in its analysis of our performance:

•

“Adjusted net income” and “adjusted diluted earnings per share” exclude certain significant items, which include incremental income tax benefit related to the reversal of the valuation allowance on our net deferred tax assets, incremental income tax benefit related to Illinois corporate income tax rate increases, incremental income tax expense or benefit related to federal corporate income tax reductions, impairment charges on assets held for sale, merger-related expenses, and core system conversion expenses adjusted for applicable income tax. Management believes the significant items are not indicative of or useful to measure the Company’s operating performance on an ongoing basis.

•

“Adjusted non-interest expense” is non-interest expense excluding certain significant items, which include impairment charges on assets held for sale, merger-related expenses, and core system conversion expenses.

•

“Adjusted efficiency ratio” is adjusted non-interest expense less amortization of intangible assets divided by net interest income and non-interest income. Management believes the metric is an important measure of the Company’s operating performance on an ongoing basis.

•

“Adjusted non-interest expense to average assets” is adjusted non-interest expense divided by average assets. Management believes the metric is an important measure of the Company’s operating performance on an ongoing basis.

•

“Adjusted return on average stockholders’ equity” is adjusted net income divided by average stockholders’ equity. Management believes the metric is an important measure of the Company’s operating performance on an ongoing basis.

•

“Adjusted return on average assets” is adjusted net income divided by average assets. Management believes the metric is an important measure of the Company’s operating performance on an ongoing basis.

•

“Non-interest income to total revenues” is non-interest income divided by net interest income plus non-interest income. Management believes that it is standard practice in the industry to present non-interest income as a percentage of total revenue. Accordingly, management believes providing these measures may be useful for peer comparison.

•

“Pre‑tax pre‑provision net income” is pre‑tax income plus the provision for loan and lease losses. Management believes this metric is important due to the tax benefit resulting from the reversal of the net deferred tax asset valuation allowance, the decrease in the federal corporate income tax rate, and the increase in the Illinois state corporate income tax rate. The metric demonstrates income excluding the tax provision or benefit and the provision for loan and lease losses, and enables investors and others to assess the Company’s ability to generate capital to cover credit losses through a credit cycle.

•

“Adjusted pre-tax pre-provision net income” is pre-tax pre-provision net income excluding certain significant items, which include impairment charges on assets held for sale, merger-related expenses, and core system conversion expenses. Management believes the metric is an important measure of the Company’s operating performance on an ongoing basis.

•

“Pre ‑tax pre ‑provision return on average assets” is pre-tax income plus the provision for loan and lease losses, divided by average a ssets. Management believes this metric is important due to the change in tax expense or benefit resulting from the recent decrease in the federal corporate income tax rate and the recent increase in the Illinois state income tax rate. The ratio demonstrate s profitability excluding the tax provision or benefit and excludes the provision for loan and lease losses. “ Adjusted pre-tax pre-provision return on average assets ” excludes certain significant items, which include impairment charges on assets held for s ale, merger- related expenses, and core system conversion expenses .

•

“Tangible common equity” is defined as total stockholders’ equity reduced by preferred stock and goodwill and other intangible assets. Management does not consider servicing assets as an intangible asset for purposes of this calculation.

•

“Tangible assets” is defined as total assets reduced by goodwill and other intangible assets. Management does not consider servicing assets as an intangible asset for purposes of this calculation.

•

“Tangible book value per common share” is calculated as tangible common equity, which is stockholders’ equity reduced by preferred stock and goodwill and other intangible assets, divided by total shares of common stock outstanding. Management believes this metric is important due to the relative changes in the book value per share exclusive of changes in intangible assets.

•

“Tangible common equity to tangible assets” is calculated as tangible common equity divided by tangible assets, which is total assets reduced by goodwill and other intangible assets. Management believes this metric is important to investors and analysts interested in relative changes in the ratio of total stockholders’ equity to total assets, each exclusive of changes in intangible assets.

•

“Tangible net income available to common stockholders” is net income available to common stockholders excluding after-tax intangible asset amortization.

•

“Adjusted tangible net income available to common stockholders” is tangible net income available to common stockholders excluding certain significant items. Management believes the metric is an important measure of the Company’s operating performance on an ongoing basis.

•

“Return on average tangible common stockholders’ equity” is tangible net income available to common stockholders divided by average tangible common stockholders’ equity. Management believes the metric is an important measure of the Company’s operating performance on an ongoing basis.

•

“Adjusted return on average tangible common stockholders’ equity” is adjusted tangible net income available to common stockholders divided by average tangible common stockholders’ equity. Management believes the metric is an important measure of the Company’s operating performance on an ongoing basis.

We believe that these non‑GAAP financial measures provide useful information to its management and investors that is supplementary to our financial condition, results of operations and cash flows computed in accordance with GAAP; however, we acknowledge that our non‑GAAP financial measures have a number of limitations. As such, you should not view these disclosures as a substitute for results determined in accordance with GAAP financial measures that we and other companies use. Management also uses these measures for peer comparison.

Our ability to predict results or the actual effects of future plans, strategies or events is inherently uncertain. Factors which could cause actual results or conditions to differ materially from those reflected in forward-looking statements include:

•

uncertainty regarding geopolitical developments and the United States and global economic outlook that may continue to impact market conditions or affect demand for certain banking products and services;

•

unforeseen credit quality problems or changing economic conditions that could result in charge-offs greater than we have anticipated in our allowance for loan and lease losses or changes in the value of our investments;

•

commercial real estate market conditions in the Chicago metropolitan area and southern Wisconsin;

•

deterioration in the financial condition of our borrowers resulting in significant increases in our loan and lease losses and provisions for those losses and other related adverse impacts to our results of operations and financial condition;

•

estimates of fair value of certain of our assets and liabilities, which could change in value significantly from period to period;

•

competitive pressures in the financial services industry relating to both pricing and loan and lease structures, which may impact our growth rate;

unanticipated developments in pending or prospective loan and/or lease transactions or greater-than-expected pay downs or payoffs of existing loans and leases;

•

inaccurate assumptions in our analytical and forecasting models used to manage our loan and lease portfolio;

•

unanticipated changes in monetary policies of the Federal Reserve or significant adjustments in the pace of, or market expectations for, future interest rate changes;

•

availability of sufficient and cost-effective sources of liquidity or funding as and when needed;

•

our ability to retain or the loss of key personnel or an inability to recruit appropriate talent cost-effectively;

•

adverse effects on our information technology systems resulting from failures, human error or cyberattack, including the potential impact of disruptions or security breaches at our third-party service providers, any of which could result in an information or security breach, the disclosure or misuse of confidential or proprietary information, significant legal and financial losses and reputational harm;

•

greater-than-anticipated costs to support the growth of our business, including investments in technology, process improvements or other infrastructure enhancements, or greater-than-anticipated compliance or regulatory costs and burdens;

•

the impact of possible future acquisitions, if any, including the costs and burdens of integration efforts;

•

the ability of the Company to receive dividends from its subsidiaries;

•

changes in Small Business Administration (“SBA”) and U.S. Department of Agriculture (“USDA”) U.S. government guaranteed lending rules, regulations and loan products, including specifically the SBA Section 7(a) program, changes in SBA or USDA standard operating procedures or changes to the status of Byline Bank as an SBA Preferred Lender;

•

changes in accounting principles, policies and guidelines applicable to bank holding companies and banking generally;

•

the impact of a possible change in the federal or state income tax rate on our deferred tax assets and provision for income tax expense;

•

the possibility that any of the anticipated benefits of acquisitions will not be realized or will not be realized within the expected time period;

•

the risk that the integration of acquisition operations will be materially delayed or will be more costly or difficult than expected;

•

the effect of mergers on customer relationships and operating results; and

•

other risks detailed from time to time in filings we make with the SEC.

These risks and uncertainties should be considered in evaluating any forward-looking statements, and undue reliance should not be placed on such statements. Forward looking statements speak only as of the date they are made. You should also consider the risks, assumptions and uncertainties set forth in the “Risk Factors” section of this Form 10-Q and in our Annual Report on Form 10-K for the year ended December 31, 2018, and the “Management’s Discussion and Analysis of Financial Condition and Results of Operations” section of this Form 10-Q, as well as those set forth in the reports we file with the SEC. We assume no obligation to update any of these statements in light of new information, future events or otherwise unless required under the federal securities laws.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

Our primary market risk is interest rate risk, which is defined as the risk of loss of net interest income or net interest margin because of changes in interest rates.

We seek to measure and manage the potential impact of interest rate risk. Interest rate risk occurs when interest-earning assets and interest-bearing liabilities mature or re-price at different times, on a different basis or in unequal amounts. Interest rate risk also arises when our assets, liabilities and off-balance sheet contracts each respond differently to changes in interest rates, including as a result of explicit and implicit provisions in agreements related to such assets and liabilities and in off-balance sheet contracts that alter the applicable interest rate and cash flow characteristics as interest rates change. The two primary examples of such provisions that we are exposed to are the duration and rate sensitivity associated with indeterminate-maturity deposits (e.g., non-interest-bearing checking accounts, negotiable order of withdrawal accounts, savings accounts and money market deposits accounts and the rate of prepayment associated with fixed-rate lending and mortgage-backed securities. Interest rates may also affect loan demand, credit losses, mortgage origination volume and other items affecting earnings.

We are also exposed to interest rate risk through the retained portion of the U.S. government guaranteed loans we make and the related servicing rights. Our U.S. government guaranteed loan portfolio is comprised primarily of SBA 7(a) loans, virtually all of which are quarterly or monthly adjustable with the prime rate. The SBA portfolio reacts differently in a rising rate environment than our other non-guaranteed portfolios. Generally, when interest rates rise, the prepayments in the SBA portfolio tend to increase.

Our management of interest rate risk is overseen by our bank’s asset liability committee, and is chaired by Byline Bank’s Treasurer, based on a risk management infrastructure approved by our board of directors that outlines reporting and measurement requirements. In particular, this infrastructure sets limits and management targets, calculated monthly, for various metrics, including our economic value sensitivity, our economic value of equity and net interest income simulations involving parallel shifts in interest rate curves, steepening and flattening yield curves, and various prepayment and deposit duration assumptions. Our risk management infrastructure also requires a periodic review of all key assumptions used, such as identifying appropriate interest rate scenarios, setting loan prepayment rates based on historical analysis, non-interest-bearing and interest-bearing demand deposit durations based on historical analysis and the targeted investment term of capital.

We manage the interest rate risk associated with our interest-bearing liabilities by managing the interest rates and tenors associated with our borrowings from the FHLB and deposits from our customers that we rely on for funding. In particular, from time t o time we use special offers on deposits to alter the interest rates and tenors associated with our interest-bearing liabilities. We manage the interest rate risk associated with our interest-earning assets by managing the interest rates and tenors associa ted with our investment and loan portfolios, from time to time purchasing and selling investment securities and selling residential mortgage loans in the secondary market.

We utilize interest rate swaps to hedge our interest rate exposure on commercial loans when it meets our clients’ and Byline Bank’s needs. Typically, customer interest rate swaps are for terms of more than five years. As of September 30, 2019, we had a notional amount of $296.7 million of interest rate swaps outstanding which includes customer swaps and those on Byline Bank’s balance sheet. The overall effectiveness of our hedging strategies is subject to market conditions, the quality of our execution, the accuracy of our valuation assumptions, the associated counterparty credit risk and changes in interest rates.

We do not engage in speculative trading activities relating to interest rates, foreign exchange rates, commodity prices, equities or credit.

We are also subject to credit risk. Credit risk is the risk that borrowers or counterparties will be unable or unwilling to repay their obligations in accordance with the underlying contractual terms. We manage and control credit risk in the loan and lease portfolio by adhering to well-defined underwriting criteria and account administration standards established by management. Written credit policies document underwriting standards, approval levels, exposure limits and other limits or standards deemed necessary and prudent. Portfolio diversification at the obligor, industry, product and/or geographic location levels is actively managed to mitigate concentration risk. In addition, credit risk management also includes an independent credit review process that assesses compliance with commercial, real estate and other credit policies, risk ratings, and other critical credit information. In addition to implementing risk management practices that are based upon established and sound lending practices, we adhere to sound credit principles. We understand and evaluate our customers’ borrowing needs and capacity to repay, in conjunction with their character and history.

Evaluation of Interest Rate Risk

We use a net interest income simulation model to measure and evaluate potential changes in our net interest income. We run various hypothetical interest rate scenarios at least monthly and compare these results against a scenario with no changes in interest rates. Our net interest income simulation model incorporates various assumptions, which we believe are reasonable but which may have a significant impact on results such as: (1) the timing of changes in interest rates, (2) shifts or rotations in the yield curve, (3) re-pricing characteristics for market-rate-sensitive instruments on and off balance sheet, (4) differing sensitivities of financial instruments due to differing underlying rate indices, (5) the effect of interest rate limitations in our assets, such as floors and caps, (6) the effect of our interest rate swaps and (7) overall growth and repayment rates and product mix of assets and liabilities. Because of limitations inherent in any approach used to measure interest rate risk, simulation results are not intended as a forecast of the actual effect of a change in market interest rates on our results but rather as a means to better plan and execute appropriate asset-liability management strategies and manage our interest rate risk.

P otential change s to our net interest income in hypothetical rising and declining rate scenarios calculated as of September 30, 2019 is presented in the fol lowing table. The projections assume (1) immediate, parallel shifts downward of the yield curve of 100 basis points and immediate, parallel shifts upward of the yield curve of 100, 200, 300 and 400 basis points and (2) gradual shifts downward of 100 and 20 0 basis points over 12 months and gradual shifts upward of 100 and 200 basis points over 12 months. In the current interest rate environment, a downward shift of the yield curve of 300 and 400 basis points does not provide us with meaningful results. In a downward parallel shift of the yield curve, interest rates at the short-end of the yield curve are not modeled to decline any further than 0%. For the dynamic balance sheet and rate shift scenarios, we assume interest rates follow a forward yield curve and then ramp it up by 1/12th of the total change in rates each month for twelve months.

	Estimated Increase (Decrease) in Net Interest Income
	Twelve Months Ending			Twelve Months Ending
Change in Market Interest Rates as of September 30, 2019	September 30, 2020			September 30, 2021
Immediate Shifts
+400 basis points		15.8	%		20.8	%
+300 basis points		12.4	%		16.5	%
+200 basis points		8.6	%		11.9	%
+100 basis points		4.3	%		6.3	%
-100 basis points		(7.6	)%		(11.5	)%
-200 basis points		(15.4	)%		(22.3	)%

Dynamic Balance Sheet and Rate Shifts
+200 basis points		6.2	%
+100 basis points		3.4	%
-100 basis points		(2.4	)%
-200 basis points		(6.6	)%

The results of this simulation analysis are hypothetical, and a variety of factors might cause actual results to differ substantially from what is depicted. For example, if the timing and magnitude of interest rate changes differ from those projected, our net interest income might vary significantly. Non-parallel yield curve shifts such as a flattening or steepening of the yield curve or changes in interest rate spreads, would also cause our net interest income to be different from that depicted. An increasing interest rate environment could reduce projected net interest income if deposits and other short-term liabilities re-price faster than expected or faster than our assets re-price. Actual results could differ from those projected if we grow assets and liabilities faster or slower than estimated, if we experience a net outflow of deposit liabilities or if our mix of assets and liabilities otherwise changes. Actual results could also differ from those projected if we experience substantially different repayment speeds in our loan portfolio than those assumed in the simulation model. Finally, these simulation results do not contemplate all the actions that we may undertake in response to potential or actual changes in interest rates, such as changes to our loan, investment, deposit, funding or hedging strategies.

On October 30, 2019, the Federal Reserve Bank announced a reduction in its benchmark interest rate of 25 basis points. Following the announcement, we reduced the Prime Rate from 5.00% to 4.75% on our variable rate loans effective October 31, 2019. We estimate the reduction will decrease net interest income by approximately $560,000 over the remainder of 2019.

Item 4. Controls and Procedures.

The Company’s management, including our President and Chief Executive Officer and our Chief Financial Officer, have evaluated the effectiveness of our “disclosure controls and procedures” (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934 (the “Exchange Act”)), as of the end of the period covered by this report. Based on such evaluation, our President and Chief Executive Officer and our Chief Financial Officer have concluded that, as of September 30, 2019, the Company’s disclosure controls and procedures were effective to provide reasonable assurance that the information required to be disclosed by the Company in the reports it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC and is accumulated and communicated to the Company’s management, including our President and Chief Executive Officer and our Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

Changes in Internal Control Over Financial Reporting

There was no change in our internal control over financial reporting during the quarter ended September 30, 2019, that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

The design of any system of controls and procedures is based in part upon certain assumptions about the likelihood of future events. There can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions, regardless of how remote.
