See accompanying Notes to Unaudited Interim Condensed Consolidated Financial ~~Statements~~Statements.

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, ~~2017~~2018 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, 2017, 2016, and 2015.

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.

On October 17, 2018, we entered a definitive merger agreement with Oak Park River Forest Bankshares, Inc. (which we refer to as “Oak Park River Forest”), the parent company of Community Bank of Oak Park River Forest, to which the Company will acquire Oak Park River Forest through the merger of Oak Park River Forest with and into the Company, followed immediately by the merger of Community Bank of Oak Park River Forest with and into Byline Bank. At such time, Community Bank of Oak Park River Forest’s banking offices will become banking offices of the Bank. The above described merger agreements are anticipated to be completed during the first half of 2019, subject to the satisfaction or waiver of the conditions included in the merger agreement. No other 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.

During the three months ended March 31, 2018, we revised our previously issued 2017 consolidated financial statements to properly record a deferred tax liability associated with the bad debt recapture assumed from the acquisition of Ridgestone Financial Services, Inc. (“Ridgestone”) and its subsidiaries on October 14, 2016. The acquisition of Ridgestone was accounted for using the acquisition method of accounting in accordance with ASC Topic 805, Business Combinations (“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. The fair value adjustments associated with this transaction were finalized during the fourth quarter of 2017.

We evaluated the effect of the error to our previously issued consolidated financial statements in accordance with Securities and Exchange Commission Staff Accounting Bulletin No. 99 and No. 108, and, based upon quantitative and qualitative factors, determined that the error was not material to our previously issued consolidated financial statements. Accordingly, we have reflected the change in 2017 and revised our Consolidated Statements of Financial Condition disclosed herein. Consolidated financial statements for periods not presented herein will be revised, as applicable, as they are included in future filings.

All financial information presented in the accompanying notes to these consolidated financial statements was revised to reflect the change. The change did not affect net income or stockholders’ equity for the periods impacted.

The following table presents the effect of the aforementioned revisions to our Consolidated Statements of Financial Condition as of December 31, 2017:

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.

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 ~~Topic~~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 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. Under the terms of ASU No. 2015-14 the standard is effective for interim and annual periods beginning after December 15, 2017. Early application is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. For financial reporting purposes, the standard allows for either full retrospective adoption, meaning the standard is applied to all of the periods presented, or modified retrospective adoption, meaning the standard is applied only to the most current period presented in the financial statements with the cumulative effect of initially applying the standard recognized at the date of initial application. The Company is currently evaluating the provisions of ASU No. 2014-09 to determine the potential impact the standard will have on the Company’s Consolidated Financial Statements. As a financial institution, the Company’s largest component of revenue, interest income, is excluded from the scope of this ASU. The Company is currently evaluating which, if any, of its sources of non-interest income will be impacted by this ASU. Assuming the Company remains an emerging growth company, the Company expects to adopt this new guidance on January 1, 2019, with

a cumulative effect adjustment to opening retained earnings, if such adjustment is deemed to be significant. In April 2016, FASB issued ASU No. 2016-10, Identifying Performance Obligations and Licensing. The amendments in this ASU do not change the core principle of the guidance in Topic 606. Rather, 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. The amendments in this ASU affect the guidance in ASU 2014-09, discussed above, which is not yet effective. The effective date and transition requirements for the amendments in this ASU are the same as the effective date and transition requirements in Topic 606, Revenues from Contracts with Customers. The Company is evaluating the provisions of this ASU in conjunction with ASU No. 2014-09 to determine the potential impact Topic 606 and its amendments will have on the Company’s Consolidated Financial Statements.

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 do not change the core principle of the guidance in Topic 606. Rather, the amendments in this ASU affect only several narrow aspects of Topic 606. The amendments in this ASU affect the guidance in ASU 2014-09, discussed above, which is not yet effective. The effective date and transition requirements for the amendments in this ASU are the same as the effective date and transition requirements in Topic 606. The Company is evaluating the provisions of this ASU in conjunction with ASU No. 2014-09 to determine the potential impact Topic 606 and its amendments will have on the Company’s Consolidated Financial Statements.

(Table dollars in thousands, except share and ~~Measurement of Financial Assets and Financial Liabilities~~per share data) (Unaudited)

In ~~January 2016,~~November 2017, FASB issued ASU No. ~~2016-01,~~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, Revenue from Contracts with Customers. The SAB modified SAB Topic 13, Revenue Recognition. ASU 2017-14 supersedes various SEC paragraphs and amends an SEC paragraph pursuant to the issuance of SAB 116. The Company is evaluating the provisions of this ASU in conjunction with ASU No. 2014‑09 to determine the potential impact Topic 606 and its amendments will have on the Company’s Consolidated Financial Statements.

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 Financial 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 remeasured 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 the 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 value 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 realize 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 of financial asset (that is, securities or loans and receivables) on the balance sheet or in the accompanying notes to the financial statements. The amendments in this ASU are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company is currently evaluating the provisions of ASU No. 2016-01 to determine the potential impact the new standard will have on the Company’s Consolidated Financial Statements. Assuming the Company remains an emerging growth company, the new authoritative guidance will be effective for reporting periods beginning January 1, 2019 and is not expected to have a significant impact on the Company’s Consolidated Financial Statements.

In March 2018, FASB issued ASU No. 2018-03, Recognition and Measurement of Financial Assets and Financial Liabilities. The ASU clarifies the guidance in ASU No. 2016-01. The amendments in this ASU are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years beginning after June 15, 2018. The Company is currently evaluating the provisions of ASU No. 2018-03 to determine the potential impact the new standard will have on the Company’s Consolidated Financial Statements. Assuming the Company remains an emerging growth company, the new authoritative guidance will be effective for reporting periods beginning January 1, 2019 and is not expected to have a significant 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. Lessees will no longer be provided with a source of off-balance sheet financing. 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. Assuming the Company remains an emerging growth company, the new authoritative guidance will be effective for reporting periods after January 1, 2020. The Company expects an increase in assets and liabilities as a result of recognizing additional lease contracts where the Company is a lessee.

~~The Company expects an increase in assets and liabilities as a result of recognizing additional lease contracts where the Company is lessee.~~

Derivatives and Hedging (Topic 815) ~~In March 2016, FASB issued ASU No. 2016-05,~~ ~~Effect of Derivative Contract Novations on Existing Hedge Accounting Relationships~~. The amendments in this ASU clarify that a change in the counterparty to a derivative instrument that has been designated as the hedging instrument under Topic 815 (Derivatives and Hedging) does not, in and of itself, require dedesignation of that hedging relationship provided that all other hedge accounting criteria continue to be met. The amendments in this ASU are effective for financial statements issued for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. An entity has an option to apply the amendments in this ASU on either a prospective basis or a modified retrospective basis. Early adoption is permitted, including adoption in an interim period. This ASU became effective for the Company on January 1, 2017 and did not have a material impact on the Company’s Consolidated Financial Statements.

~~In March 2016, FASB issued ASU No. 2016-06,~~ ~~Contingent Put and Call Options in Debt Instruments~~. The amendments in this ASU clarify the requirements for assessing whether contingent call (put) options that can accelerate the payment of principal on debt instruments are clearly and closely related to their debt hosts. To determine how to account for debt instruments with embedded features, including contingent put and call options, an entity is required to assess whether the embedded derivatives must be bifurcated from the host contract and accounted for separately. Part of this assessment consists of evaluating whether the embedded derivative features are clearly and closely related to the debt host. Under existing guidance, for contingently exercisable options to be considered clearly and closely related to a debt host, they must be indexed only to interest rates or credit risk. ASU 2016-06 addresses inconsistent interpretations of whether an event that triggers an entity’s ability to exercise the embedded contingent option must be indexed to interest rates or credit risk for that option to qualify as clearly and closely related. Diversity in practice has developed because the existing four-step decision sequence in ASC 815 focuses only on whether the payoff was indexed to something other than an interest rate or credit risk. As a result, entities have been uncertain whether they should (1) determine whether the embedded features are clearly and closely related to the debt host solely on the basis of the four-step decision sequence or (2) first apply the four-step decision sequence and then also evaluate whether the event triggering the exercisability of the contingent put or call option is indexed only to an interest rate or credit risk. This ASU clarifies that in assessing whether an embedded contingent put or call option is clearly and closely related to the debt host, an entity is required to perform only the four-step decision sequence in ASC 815 as amended by this ASU. The entity does not have to separately assess whether the event that triggers its ability to exercise the contingent option is itself indexed only to interest rates or credit risk. The amendments in this ASU are effective for financial statements issued for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. This ASU became effective for the Company on January 1, 2017 and did not have a material impact on the Company’s Consolidated Financial Statements.

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 new authoritative guidance will be effective for reporting periods after January 1, 2019 with early adoption permitted. The Company is evaluating the new guidance and its impact on the Company’s Consolidated Statements of Operations and Consolidated Statements of Financial Condition.

Compensation—Stock Compensation (Topic 718) ~~In March 2016, FASB issued ASU No. 2016-09,~~ ~~Improvements to Employee Share-Based Payment Accounting~~. FASB issued this ASU as part of its Simplification Initiative. The areas for simplification in this ASU involve several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. Amendments in this ASU relate to the timing of when excess tax benefits are recognized, minimum statutory withholding requirements, forfeitures, and intrinsic value should be applied using a modified retrospective transition method by means of a cumulative-effect adjustment to equity as of the beginning of the period in which the guidance is adopted. Amendments related to the presentation of employee taxes paid on the statement of cash flows when an employer withholds shares to meet the minimum statutory withholding requirement should be applied retrospectively. Amendments in this ASU require recognition of excess tax benefits and tax deficiencies in the income statement and the practical expedient for estimating expected term should be applied prospectively.

An entity may elect to apply the amendments in this ASU related to the presentation of excess tax benefits on the statement of cash flows using either a prospective transition method or a retrospective transition method. The amendments in

this ASU are effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods. This ASU became effective for the Company on January 1, 2017 and did not have a material impact on the Company’s Consolidated Financial Statements.

In May 2017, the FASB issued ASU 2017-09, Scope of Modification Accounting. The ~~new standard provides~~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. ~~This pronouncement~~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) or 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 ~~reporting~~periods, and interim periods within those annual periods, beginning after December 15, ~~2017 but early~~2017. Early adoption is ~~permitted.~~permitted, including adoption in any interim period, for reporting periods for which financial statements have not yet been issued.

The Company is ~~currently~~ evaluating the new guidance and its impact on the Company’s Consolidated Statements of ~~adopting this guidance.~~Operations and Consolidated Statements of Financial Condition.

In June 2018, the FASB issued ASU 2018-07, Improvements to Nonemployee Share-based Payment Accounting. The amendments in the ASU expands the scope of Topic 718 to include share-based payments issued to nonemployees for goods and services, in order to align the accounting for share-based payments to employees and nonemployees to reduce cost and complexity to improve financial reporting. The amendments are effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2018. Early adoption is permitted, including adoption in any interim period, for reporting periods for which financial statements have not yet been issued, but no earlier than the Company’s adoption date of Topic 606, Revenue from Contracts with Customers. Assuming the Company remains an emerging growth company, the new authoritative guidance will be effective for reporting periods after January 1, 2019. The Company is evaluating the new guidance and its impact on the Company’s Consolidated Statements of Operations and Consolidated Statements of Financial Condition.

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 decision useful to users of the financial statements. The amendments in this ASU will be effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Assuming the Company remains an emerging growth company, the new authoritative guidance will be effective for reporting periods after January 1, 2021. The Company is still evaluating the effects this ASU will have on the Company’s Consolidated Financial Statements. While the Company has not quantified the

impact of this ASU, it does expect changing from the current incurred loss model to an expected loss model will result in an earlier recognition of losses.

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 interest 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 of 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 application 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. Assuming the Company remains an emerging growth company, the new authoritative guidance will be effective for reporting periods after January 1, 2019. The Company is currently evaluating the provisions of ASU No. 2016-15 to determine the potential impact the new standard will have on the Company’s Consolidated Financial Statements.

In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (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. Theamendment is effective for annual reporting periods beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption of the update is permitted. Assuming the Company remains an emerging growth company, the new authoritative guidance will be effective for reporting periods after January 1, 2019. The Company does not expect this ASU to have a material impact on the Company’s Consolidated Financial Statements.

Income Taxes (Topic 740) In October 2016, the FASB issued ASU No. 2016-16, Income Taxes, Intra-Entity Transfers of Assets Other Than Inventory. The ASU was issued to improve the accounting for income tax consequences of intra-entity transfers of assets other than inventory. Current GAAP prohibits the recognition of current and deferred income taxes for an intra-entity asset transfer until the asset has been sold to an outside party; this update clarifies that an entity should recognize the income tax consequences of an intra-entity transfer of assets other than inventory when the transfer occurs. The amendment is effective for annual reporting periods beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption of the update is permitted. Assuming the Company remains an emerging growth company, the new authoritative guidance will be effective for reporting periods after January 1, 2019. The Company does not expect this ASU to have a material impact on the Company’s Consolidated Financial Statements.

~~Consolidation (Topic 810)~~ ~~In October 2016, the FASB issued ASU No. 2016-17,~~ ~~Consolidation~~, Interests Held through Related Parties That Are under Common Control. The ASU was issued to amend the consolidation guidance on how a reporting entity that is the single decision maker of a variable interest entity (“VIE”) should treat indirect interests in the entity held through related parties that are under common control with the reporting entity when determining whether it is the primary beneficiary of that VIE. The primary beneficiary of a VIE is the reporting entity that has a controlling financial interest in a VIE and, therefore, consolidates the VIE. A reporting entity has an indirect interest in a VIE if it has a direct interest in a related party that, in turn, has a direct interest in the VIE. The amendment is effective for annual reporting periods beginning after December 15, 2016, and interim periods within those fiscal years. Early adoption of the update is permitted. The Company adopted this new authoritative guidance on January 1, 2017 and it did not have an 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. Early adoption is permitted. Assuming the Company remains an emerging growth company, the new authoritative guidance will be effective for reporting periods after January 1, 2019. The Company does not expect a material impact of this ASU on the Company’s Consolidated Financial Statements.

Intangibles—Goodwill and Other (Topic 350) In January 2017, FASB issued ASU No. 2017-04, Simplifying the Test for Goodwill Impairment. The amendments in this ASU are intended to reduce the cost and complexity of the goodwill impairment test by eliminating step two from the impairment test. The amendments modify the concept of impairment from the condition that exists when the carrying amount of goodwill exceeds its implied fair value to the condition that exists when the carrying amount of a reporting unit exceeds its fair value. Under the amendments in this ASU, an entity will perform its annual, or interim, goodwill impairment test by comparing the fair value of the reporting unit with its carrying amount. An impairment charge should be recognized for the amount which the carrying amount exceeds the reporting unit’s fair value;

however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. The amendments in this ASU are effective for the Company’s annual or any interim goodwill impairment test in fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company is early ~~adopting~~adopted these amendments in 2017, ~~and does~~which did not ~~expect~~have a material impact on the Company’s Consolidated Financial Statements.

Other Income (Subtopic 610-20) In February 2017, the FASB issued ASU No. 2017-05, Other Income-Gains and Losses from the Derecognition of Nonfinancial Assets. This ASU will clarify the scope of Subtopic 610-20 and add guidance for partial sales of nonfinancial assets. The amendments should be applied either on retrospectively to each period presented or with a modified retrospective approach. The amendment is effective for annual periods beginning after December 15, 2018, and interim periods within annual periods beginning after December 15, 2019. The Company is currently evaluating the provisions of ASU No. 2017-05 to determine the potential impact the new standard 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.

Earnings Per Share (Topic 260), Distinguishing Liabilities from Equity (Topic 480), and Derivatives and Hedging (Topic 815) In July 2017, FASB issued ASU No. 2017-11, (Part I) Accounting for Certain Financial Instruments with Down Round Features, (Part II) Replacement of the Indefinite Deferral for Mandatorily Redeemable Financial Instruments of Certain Nonpublic Entities and Certain Mandatorily Redeemable Noncontrolling Interests with a Scope Exception. The ASU simplifies the accounting for certain financial instruments with down round features, a provision in an equity-linked financial instrument (or embedded feature) that provides a downward adjustment of the current exercise price based on the price of future equity offerings. Down round features are common in warrants, convertible preferred shares, and convertible debt instruments. The ASU requires companies to disregard the down round feature when assessing whether the instrument is indexed to its own stock, for purposes of determining liability or equity classification. Companies that provide earnings per share (EPS) data will adjust their basic EPS calculation for the effect of the feature when triggered (i.e., when the exercise price of the related equity-linked financial instrument is adjusted downward because of the down round feature) and will also recognize the effect of the trigger within equity. 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. 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. 2017‑11 to determine the potential impact the new standard will have on the Company’s Consolidated Financial Statements.

Income Statement—Reporting Comprehensive Income (Topic 220) In February 2018, FASB issued ASU No. 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. The ASU helps organizations address certain stranded income tax effects in accumulated other comprehensive income (AOCI) resulting from the Tax Cuts and Jobs Act. The ASU provides reporting entities with an option to reclassify stranded tax effects within AOCI to retained earnings in each period in which the effect of the change in the U.S. federal corporate income tax rate in the Tax Cuts and Jobs Act (or portion thereof) is recorded. The ASU requires reporting entities to disclose: a description of the accounting policy for releasing income tax effects from AOCI; whether they elect to reclassify the stranded income tax effects from the Tax Cuts and Jobs Act; and information about the other income tax effects that are reclassified. The amendments affect any organization that is required to apply the provisions of Topic 220, Income Statement—Reporting

Comprehensive Income, and has items of other comprehensive income for which the related tax effects are presented in other comprehensive income as required by GAAP. The amendments are effective for annual periods beginning after December 15, 2018, and interim periods within those fiscal years. The Company early adopted the new guidance on January 1, 2018. The adoption did not impact the Company’s Statements of Operations, and resulted in a reclassification of $763,000 from accumulated other comprehensive income (loss) to retained earnings.

Financial Services—Depository and Lending (Topic 942) In May 2018, FASB issued ASU No. 2018-06, Codification Improvements to Topic 942, Depository and Lending—Income Taxes. The amendments in this ASU supersede the guidance within Subtopic 942-741 that has been rescinded by the OCC and no longer relevant. A cross-reference between Subtopic 740-30, Income Taxes—Other Considerations or Special Areas,and Subtopic 942-740 is being added to the remaining guidance in Subtopic 740-30 to improve the usefulness of the codification. The amendments in this Update are effective upon issuance, as no accounting requirements are affected. The amendments in this ASU do 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: in lieu of a rollforward for Level 3 fair value measurements, a nonpublic entity is required to disclose transfers into and out of Level 3 of the fair value hierarchy and purchases and issues of Level 3 assets and liabilities;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; andclarify 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; andthe range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. This guidance is effective for annual and interim periods beginning after December 15, 2019. Early adoption is permitted. Assuming the Company remains an emerging growth company, the new authoritative guidance will be effective for reporting periods after January 1, 2020. The Company early adopted these amendments in 2018, which did not have a material impact on the Company’s Consolidated Financial Statements.

On ~~October 14, 2016,~~May 31, 2018, the Company acquired all common stock of ~~Ridgestone Financial Services,~~First Evanston Bancorp, Inc. (“~~Ridgestone”~~First Evanston”) and its subsidiaries ~~under the terms~~pursuant to an Agreement and Plan of ~~a definitive merger agreement (“~~Merger, dated as of November 27, 2017 (the “Merger Agreement”) ~~dated June 9, 2016. Ridgestone~~. First Evanston operated two ~~wholly-owned~~wholly owned subsidiaries, ~~Ridgestone~~First Bank & Trust and ~~RidgeStone Capital~~First Evanston Bancorp Trust I,I. First Evanston was merged with and ~~specialized in government guaranteed lending~~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 ~~a participant~~the surviving bank. The acquisition improves the Company’s footprint in the ~~SBA~~Chicagoland market, diversifies its commercial banking business, and USDA lending programs. Ridgestone provided financial services through its two full-service banking offices in Brookfield, Wisconsin and Schaumburg, Illinois. In addition, Ridgestone had loan production offices located in Wisconsin (Green Bay and Wausau), Indiana (Indianapolis) and California (Newport Beach).strengthens the core deposit base.

~~Under~~At the ~~terms~~effective time of the ~~Agreement,~~merger (the “Effective Time”), each ~~Ridgestone~~share of First Evanston’s common ~~share~~stock was converted into the right to ~~receive, at~~receive: (1) 3.994 shares of Byline’s common stock, and (2) an amount in cash equal to $27.0 million divided by the ~~election~~number of outstanding shares of First Evanston common stock as of the ~~stockholder (subject to proration as outlined~~closing date, with cash paid in lieu of any fractional shares. The per share cash consideration was based on the ~~Agreement), either cash or Company~~total $27.0 million divided by the outstanding shares of First Evanston common stock, or $16.136 per outstanding share. Based on the ~~combination~~closing price of ~~both. Total consideration included aggregate cash in the amount of $36.8 million and the issuance of 4,199,791~~ shares 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 ~~$16.25 per~~$144.5 million. Options to acquire 144,090 shares of First Evanston common ~~share.~~ 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 the issuance costs of $852,000.

The transaction resulted in goodwill of ~~$26.3~~$73.0 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. ~~Acquisition~~Merger-related expenses, including acquisition advisory expenses of $1.7 million and core system conversion expenses of $9.2 million related to the ~~Ridgestone~~First Evanston acquisition, ~~of $1.1 million~~ are reflected in non-interest expense on the Consolidated Statements of Operations for the nine months ended September 30, ~~2016. Stock issuance costs were not material. There were no contingent assets or liabilities arising from the acquisition.~~2018.

The acquisition of ~~Ridgestone~~First Evanston 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. ~~Fair values are preliminary estimates due to deferred tax assets and deferred tax liabilities.~~

The following table presents a summary of the preliminary estimates of fair values of assets acquired and liabilities assumed as of the acquisition date:

Certain securities have fair values less than amortized cost and, therefore, contain unrealized losses. At September 30, ~~2017,~~2018, the Company evaluated the securities which had an unrealized loss for other than temporary impairment and determined all declines in value to be temporary. There were ~~113 investment~~287 securities available-for-sale with unrealized losses at September 30, ~~2017, of which only one had a continuous~~2018. There were 54 securities held-to-maturity with unrealized ~~loss position for 12 consecutive months or longer that is greater than 5% of amortized cost.~~losses at September 30, 2018. 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 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 condition 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.

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 ~~rates~~rate for the nine months ended September 30, 2018 and 2017 was 24.4%. The current effective tax rate reflects the passage of the Tax Cuts and ~~2016 were 24.4% and (8.6)%~~Jobs Act (the “Tax Act”), ~~respectively.~~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.

~~Deferred~~ The re-measurement of our net deferred tax assets ~~decreased $7.4 million from $67.8 million at December 31, 2016 to $60.4 million at September 30, 2017.

As part of a budget package passed by the Legislature of the State of Illinois, the corporate income tax rate increased from 5.25% to 7.00% effective July 1, 2017. As a result of the increase in the corporate income tax rate, during the third quarter of 2017 we recorded a state income tax benefit of $4.6 million due to increased value of our deferred tax asset related to our Illinois net loss deduction.

29Net deferred tax assets decreased to$42.3 million at September 30, 2018 compared to $47.4 million at December 31, 2017. The net decrease in the total net deferred tax assets recorded as of September 30, 2018 was a result of a reduction due to the utilization of net operating loss carryforward deferred tax assets, partially offset with an increase in net deferred tax assets related to the acquisition of First Evanston.

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 ~~reaches~~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. ~~On October 12, 2017, the Company amended the credit agreement, which extended the maturity date to October 11, 2018.~~ The ~~amended revolving~~ line of credit ~~bears~~matured on October 11, 2018 and carried an interest rate at either the ~~LIBOR~~London Interbank Offered Rate (“LIBOR”) plus 250 basis points or the Prime Rate minus 25 basis points, based on the Company’s election. On October 11, 2018, the Company entered into a third amendment to the revolving credit agreement, which increased the revolving loan commitment to $10.0 million, extended the maturity of the credit facility to October 10, 2019, and makes certain other changes, including a release of the previously executed Stock Pledge Agreement dated October 13, 2016 and execution of a Negative Pledge Agreement dated October 11, 2018. The amended revolving line of credit bears interest at either the LIBOR plus 225 basis points or the Prime Rate minus 50 basis points, based on the Company’s election, which is required to be communicated ~~to CIBC~~ 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 2550 basis points. At September 30, 2018 and December 31, 2017, the line of credit has not been drawn upon, so an interest rate option has not been selected.

As part of the Ridgestone acquisition, the Company assumed the obligations to RidgeStone Capital Trust I of $1.5 million in principal amount, which was formed for the issuance of trust preferred securities. ~~Refer to Note 3—Acquisition of a Business for additional information.~~ Beginning on June 30, 2008, the interest rate reset to the five-year LIBOR plus 3.50% ~~(5.09%~~(6.38% and 5.09% at September 30, ~~2017~~2018 and December 31, ~~2016)~~2017, respectively), which is in effect until ~~September~~June 30, ~~2018~~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. Accrued interest payable was $25,000 as of September 30, 2018. There was no accrued interest payable as of December 31, 2017.

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—Acquisition of a Business for additional information. Beginning on March 15, 2010, the interest rate reset to the three-month LIBOR plus 1.78% (4.11% at September 30, ~~2017~~2018), 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 ~~December 31, 2016.~~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 $18,000 as of September 30, 2018.

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.

Legal contingencies—In the ordinary course of business, the Company and Bank have various outstanding commitments and contingent liabilities that are not recognized in the accompanying consolidated financial statements. In addition, the Company may be a defendant in certain claims and legal actions arising in the ordinary course of business. In the opinion of management, after consultation with legal counsel, the ultimate disposition of these matters is currently not expected to have a material adverse effect on the Company’s Consolidated Statements of Financial Condition.

Operating lease commitments—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 total amount of minimum rentals to be received in the future on these subleases is approximately $1.5 million, and ~~$187,000, respectively.~~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. ~~The amounts are not material.~~ 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.

Commitments to extend credit—The Bank 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 Bank has in particular classes of financial instruments.

The ~~Bank’s~~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 ~~standby~~ letters of credit is represented by the contractual or notional amount of those instruments. The Bank uses the same credit policies in making commitments and conditional obligations as it does for funded instruments. The Bank does not anticipate any material losses as a result of the commitments and ~~standby~~ letters of credit.

The following table summarizes the contract or notional amount of outstanding loan and lease commitments at September 30, ~~2017~~2018 and December 31, ~~2016~~2017:

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 Bank evaluates each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the 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).

~~Standby letters~~Letters of credit are conditional commitments issued by the Bank 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

similartransactions.The creditriskinvolvedin issuinglettersof creditis essentiallythesameas thatinvolvedin extendingloanfacilitiesto 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 ~~3.23%~~2.00% to ~~19.50%~~20.00% and maturities up to ~~2020.~~2048. Variable rate loan commitments have interest rates ranging from 2.45% to ~~8.25%~~15.00% and maturities up to ~~2040.~~2048.

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.

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.

~~A financial instrument’s~~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 thefollowingmethodsand significantassumptionsto estimatefairvalueforcertain assetsmeasuredand carriedatfairvalueon a recurringbasis:

Securities available-for-sale—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.

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 ~~2017~~2018 and ~~2016,~~2017, 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.

Servicing assets—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 future cash flows for each servicing asset, based on their unique characteristics and market-based assumptions for prepayment speeds. The present value of the future cash flows are then calculated utilizing market-based discount rate assumptions.

Derivativeinstruments—Interest rate swaps 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.

The following table presents additional information about the unobservable inputs used in the fair value measurements on recurring basis that were categorized within Level 3 of the fair value hierarchy as of September 30, ~~2017:~~2018:

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. Impaired loans that are not collateral dependent are not material.

Assetsheld forsale—Assets held for sale consist of former branch locations~~vacantland,~~and ~~a house~~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.

Other real estate owned—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, ~~2017~~2018 and December 31, ~~2016:~~2017:

The following ~~table provides a description~~methods and assumptions were used by the Company in estimating fair values of ~~the valuation technique, unobservable inputs and qualitative information about the Company’s~~other assets and liabilities ~~classified as Level 3 and measured at fair value on a non-recurring basis as of September 30, 2017:~~

~~The followingmethodsand assumptionswere used by theCompany in estimatingfairvaluesof other assetsand liabilities~~fordisclosurepurposes:

Cash and cash equivalents—For these short-term instruments, the carrying amount is a reasonable estimate of fair value.~~The fairvaluefortimecertificateswith otherbanks isbasedon themarketvaluesfor comparableinvestments.~~

Securities held-to-maturity—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.

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.

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 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.

~~Deposit liabilitie~~sDeposits—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 repurchase—The carrying amount approximates fair value due to maturities of less than ninety days.

Junior subordinated debentures—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 ~~commercial and standby~~ letters of credit—The fair values of these off-balance sheet commitments to extend credit and commercial and ~~standby~~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.

38The estimated fair values of financial instruments and levels within the fair value hierarchy are as follows:

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 September 30, 2018 and December 31, 2017. The aggregate fair value of the swaps is recorded in other assets or other liabilities with changes in fair value recorded in other comprehensive income (loss), net of taxes, to the extent effective. The amount included in accumulated other comprehensive income (loss) would be reclassified to current ~~earnings when~~interest incurred from the hedged FHLB advances ~~affect~~when it affects earnings. 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. The Company expects the hedges to remain highly effective during the remaining terms of the swaps and did not recognize any hedge ineffectiveness in current earnings during the three or nine months ended September 30, ~~2017~~2018 and ~~2016.~~2017.

Interest recorded on these swap transactions reduced FHLB interest expense by $863,000 and increased FHLB interest expense by $426,000 during the nine months ended September 30, 2018 and 2017, respectively. At September 30, 2018, the Company estimates $2.7 million of the unrealized gain to be reclassified as a decrease to interest expense during the next twelve months.

Interest expense recorded on swap transactions totaled $4,000 during the three and nine months ended September 30, 2016. At September 30, 2017, the Company estimates $249,000 of the unrealized gain to be reclassified as an increase to interest expense during the next twelve months.

Other credit derivatives—The total notional amount was $4.5 million as of September 30, 2018. There were no credit derivatives as of or for the year ended December 31, 2017. 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 an increase to other non-interest income during the three and nine months ended September 30, 2018 of $34,000 and $57,000, respectively.

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 ~~credit valuation adjustment (“CVA”)~~CVA is a fair value adjustment to the derivative to account for this risk. During the three months ended September 30, 2018, the CVA resulted in an increase to non-interest income of $13,000. During the nine months ended September 30, 2018, the CVA resulted in a decrease to non-interest income of$25,000, respectively. During the three and nine months ended September 30, 2017, the CVA resulted in a decrease to non-interest income of $6,000 and $36,000, respectively. ~~During~~

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

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.

~~The~~The Company records interest rate derivatives subject to master netting agreements at their gross value and does not offset derivative asset and liabilities on the Consolidated Statements of Financial Condition.

In June 2017, the Company adopted the 2017 Omnibus Incentive Compensation Plan (the “Omnibus Plan”) in connection with our initial public ~~offering (“IPO”).~~offering. The Omnibus Plan provides for the grant of stock options, stock appreciation rights, restricted stock, restricted stock units, dividend equivalent rights and other equity-based, equity-related or cash-based awards. A total of 1,550,000 shares of our common stock have been reserved and are available for issuance under the Omnibus Plan.

These restricted shares vest ratably over a four year period.

During 2018, the Company granted 126,157 shares of restricted common stock, par value $0.01 per share. Of this total, 101,559 restricted shares will vest ratably over four years on each anniversary of the grant date, ~~400~~11,165 restricted shares will vest ratably over three years on each anniversary of the grant date, and 2,268 restricted shares will vest on the first anniversary of the grant date, all subject to continued employment.

In addition, 11,165 performance-based restricted shares were ~~forfeited.~~included in the 2018 grant. The number of shares which may be earned under the award is dependent upon the Company’s return on average assets over a three-year period ending December 31, 2020, measured in 2018 against the Company’s internal targets and for 2019 and 2020 against a peer group consisting of publicly-traded bank holding companies ranging in asset size from 50% to 200% of the Company’s total assets. Under the award, 25% of the shares will be earned at threshold performance, 100% will be earned at target and 50th

percentile performance, and up to 125% of the shares with above target and 75th percentile performance. Any earned shares will vest on the third anniversary of the grant date. As of September 30, ~~2017,~~2018, there were ~~1,491,500~~1,355,545 shares available for future grants under the Omnibus Plan.

During October 2018, the Company granted 5,000 shares of restricted common stock. These restricted shares will vest ratably over periods ranging between three and four years.

The Company maintained a nonqualified, share-based, stock option plan adopted prior to recapitalization (“MBG Plan”). There were no options granted or exercised under this plan during the year ended December 31, ~~2016 or for the nine months ended September 30,~~ 2017. At the time of the Company’s reincorporation in Delaware in June 2017, the Board of Directors cancelled the MBG Plan and all the respective outstanding options were cancelled.

In October 2014, the Company adopted the Byline Bancorp, Inc. Equity Incentive Plan (“BYB Plan”). The maximum number of shares available for grants under this ~~Plan~~plan 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 ~~nine months~~year ended ~~September 30,~~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 ~~1,798,220~~1,654,272 shares remain outstanding under the BYB ~~Plan.~~Plan at September 30, 2018.

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 1one to 5five 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 fair values of options under the BYB Plan were determined using the following assumptions as of the grant dates:

The following table discloses the activity in shares subject to options and the weighted average exercise prices, in actual dollars, for the nine months ended September 30, ~~2017:~~2018:

Pursuant to the terms of the Merger Agreement, upon the Effective Time, each outstanding First Evanston Option held by a participant (a “Participant”) in the First Evanston Bancorp, Inc. Stock Incentive Plan (the “FEB Plan”) ceased to represent a right to acquire shares of First Evanston common stock and was assumed and converted automatically into a fully vested and exercisable adjusted option to purchase shares of Byline common stock (each an “Adjusted Option”, and collectively, the “Adjusted Options”). In accordance with the Merger Agreement, the number of shares of Byline common stock to which each such Adjusted Option relates is equal to the product (rounded down to the nearest whole share of Byline common stock) of: (a) the number of shares of First Evanston common stock subject to the First Evanston Option immediately prior to May 31, 2018, multiplied by (ii) 4.725. Each Adjusted Option has an exercise price per share of Byline common stock equal to the quotient (rounded up to the nearest whole cent) of (x) the per share exercise price of such First Evanston Option immediately prior to May 31, 2018, divided by (y) 4.725 (the “Conversion Calculation”). The description of the conversion process is based on, and qualified by, the Merger Agreement.

The following table discloses the activity in shares subject to options under the FEB Plan and the weighted average exercise prices, in actual dollars, for the nine months ended September 30, 2018:

A total of 22,765 stock options were exercised during the nine months ended September 30, 2018. During the nine months ended September 30, 2018, proceeds from the exercise of stock options were $241,000 and related tax benefit was $64,000.

All shares of restricted performance shares of First Evanston common stock (“restricted stock”) that were previously issued under and held by Participants in the FEB Plan prior to the Merger were converted into the right to receive the per share merger consideration in connection with the Merger and pursuant to the Merger Agreement. Accordingly, no shares of First Evanston restricted stock remain outstanding under the FEB Plan.

A reconciliation of the numerators and denominators for earnings per common share computations is presented below. Incremental shares represent outstanding stock options for which the exercise price is less than the average market price of the Company’s common stock during the periods presented. Options to purchase 2,312,294 and 1,798,223 shares of common stock were outstanding as of September 30, 2018 and 2017, ~~and 2016.~~respectively.

Item 2.Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following is a discussion and analysis of Byline Bancorp, Inc.’s financial condition and results of operations and should be read in conjunction with our consolidated financial statements and notes thereto included elsewhere in this report. The words “the Company,” “we,” “Byline,” “our” and “us” refer to Byline Bancorp, Inc. and its consolidated subsidiaries, unless we indicate otherwise.

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 ~~core~~traditional commercial banking ~~products,~~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 ~~Texas,~~ North Carolina ~~Florida,~~and New York, and sales representatives in Michigan, New Jersey, and Arizona. 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 ~~eighth~~sixth most active originator of ~~Small Business Administration (“SBA”)~~SBA loans in the country and the most active SBA lender in Illinois and Wisconsin, as reported by the SBA for the ~~year~~quarter ended September 30, ~~2017.~~

~~We offer traditional retail deposit products through~~2018. Following our ~~branch network, along with online, mobile and direct banking channels. The wide variety~~recent acquisition of deposit products we offer include non-interest bearing accounts, interest-bearing demand products, savings accounts, money market accounts and certificates of deposit with original maturities ranging from seven days to five years. We also offer consumer lending products, including mortgage loans, home equity loans and other consumer loans to individuals through our branch network.

~~In 2013, our predecessor, Metropolitan Bank Group~~First Evanston Bancorp, Inc. (“Metropolitan”), experienced significant credit and financial losses resulting primarily from the collapse of real estate prices during the severe economic recession occurring during 2007 through 2009, in addition to a number of regulatory and other operational challenges. Despite deterioration in asset quality and financial performance, Metropolitan maintained a high quality deposit base, an attractive branch network and strong customer loyalty, which made it an ideal candidate for a turnaround.

An investment group raised $206.7 million in equity capital to recapitalize and gain control of Metropolitan through a series of transactions by which Metropolitan merged its multiple subsidiary banks into one and an investor group acquired voting common stock and Series A Preferred Stock of Metropolitan.

~~We accounted for the Recapitalization as a business combination in accordance with Accounting Standards Codification Topic 805,~~ ~~Business Combinations~~ ~~(“Topic 805”). The transaction qualified as a recapitalization under Section 368(a)(1)(E) of the Internal Revenue Code (the “Code”~~First Evanston”) and ~~resulted in carryover treatment~~its subsidiary bank, First Bank & Trust, at the end of ~~the existing tax bases~~May 2018, we also provide trust and tax loss carryforwards treatment of the existing tax bases and tax loss carryforwards, although the utilization of tax attributes (including net operating loss carryforwards and tax credits) became subjectwealth management services to limitations under Sections 382 and 383 of the Code. Accordingly, the assets acquired and liabilities assumed were recorded at their fair value on the date of acquisition. Fair value amounts were determined in accordance with the guidance provided in ASC Topic 820, ~~Fair Value Measurements~~ (“Topic 820”). In many cases, the determination of the fair value required management to make estimates about discount rates, future expected cash flows, market conditions and other future events that are highly subjective in nature.

our customers. As of ~~the Recapitalization, which occurred on June 28, 2013,~~September 30, 2018, we had ~~$2.5~~consolidated total assets of $4.9 billion, in assets that were measured at fair value, including $1.3 billion in loans, $212.2 million in investment securities, $84.0 million of OREO and $29.7 million of core deposit intangible assets. We also acquired $2.3 billion of liabilities at fair value, including $2.2 billion of deposits and $36.9 million of borrowings. The Recapitalization resulted in goodwill of $21.2 million as the estimated fair value of liabilities assumed and consideration paid exceeded the estimated fair value of assets acquired. The goodwill is included within “Goodwill” in our consolidated statement of condition.

~~As of the Recapitalization, approximately 76.5%, or $1.0 billion, of the loans acquired in the Recapitalization were accounted for under ASC Topic 310-30,~~ ~~Accounting for Purchased Loans with Deteriorated Credit Quality. We also acquired loans with a fair value of $310.3 million that are accounted for under ASC Topic 310-20,~~ ~~Receivables—Nonrefundable Fees and Other Costs, as these specific loans did not exhibit deteriorated credit quality since origination or were loans to borrowers that had revolving privileges at the acquisition date.~~

~~Since the Recapitalization, we have added $1.5 billion in net originated~~total gross loans and leases ~~while significantly improving our asset quality to create a more diversified and balanced loan and lease portfolio. We aggressively reduced the level~~outstanding of non-performing loans and leases and other real estate owned in our portfolio as a percentage of loans and leases and real estate owned, declining to 1.4% as of September 30, 2017 and 1.1% as of December 31, 2016 from 28.2% as of March 31, 2013. In addition, we sought to optimize our deposit base by expanding the percentage of non-interest bearing deposits to$3.5 billion, total deposits ~~enhance online~~of $3.7 billion, and mobile capabilities and broaden our cash management products to better meet our customers’ needs. Since the Recapitalization, we consolidated from 88 to 57 branches, reducing our costs with minimal deposit attrition, and improving our efficiency, including through the consolidationtotal stockholders’ equity of multiple banking platforms into one. In addition to improving efficiency, consolidating our banking platforms allowed us to better manage our customer relationships and their banking activities while strengthening our governance and controls for compliance, legal and operational risk.$629.9 million.

On October 10, 2014, Byline Bank acquired certain assets and liabilities related to the small ticket leasing operation of Baytree National Bank and Trust Company and Baytree Leasing Company LLC (collectively, “Baytree”). The purchase was accounted for under the acquisition method of accounting in accordance with ASC Topic 805 and resulted in lease financing receivables of $42.0 million and goodwill of $4.5 million. There are no contingent assets or liabilities remaining from the acquisition.

In a separate but related transaction, on September 3, 2014, Byline Bank purchased approximately $55.7 million of direct finance leases that Baytree had sold to a third party. We have grown our leasing portfolio to ~~$172.3~~$189.1 million as of September 30, ~~2017.~~2018.

On October 14, 2016, we completed the acquisition of Ridgestone ~~acquisition~~Financial Services, Inc. (“Ridgestone”) and its subsidiary bank, Ridgestone Bank, under the terms of a definitive merger agreement (the “Ridgestone 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 lending programs.

On May 31, 2018, we completed the acquisition of First Evanston Bancorp, Inc. (“First Evanston”), under the terms of a definitive merger agreement (the “First Evanston 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 $931.6 million of loans, $127.1 million of securities, and total deposits of $1.0 billion.

At the effective time of the merger (the “Effective Time”), each share of ~~Ridgestone~~First Evanston’s common stock (the “First Evanston Common Stock”) was converted into the right to ~~receive,~~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 ~~election~~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 ~~shareholder and subject to proration under the terms~~outstanding shares of First Evanston Common Stock. The value of the ~~Ridgestone Agreement, either cash or shares of our common stock, or a combination of both. Total~~total merger consideration ~~included aggregate cash consideration in the amount of $36.8 million and the issuance of 4,199,791 shares of our common stock valued~~ at ~~$16.25 per common share. There were no contingent assets or liabilities arising from the acquisition.~~closing was approximately $179.1 million.

We determined that the ~~Ridgestone~~First Evanston acquisition constituted a business combination as defined by ~~ASC Topic~~Accounting Standards Codification (“ASC”) 805. Accordingly, the assets acquired and liabilities assumed were recorded at their fair value amount on the date of acquisition. Fair ~~values were~~value was determined in accordance with the guidance provided in ASC ~~Topic~~ 820. The fair values may be adjusted through the end of the measurement period, which closes at the earlier of the Company receiving all necessary information to complete the acquisition or one year from the date of acquisition. The transaction qualified for federal income tax purposes as a tax free transaction under section 368(a) of the Code.

On October 17, 2018, we entered a definitive merger agreement with Oak Park River Forest Bankshares, Inc. (“Oak Park River Forest”), the parent company of Community Bank of Oak Park River Forest, pursuant to which the Company will acquire Oak Park River Forest through the merger of Oak Park River Forest with and into the Company, followed immediately by the merger of Community Bank of Oak Park River Forest with and into Byline Bank. As of June 30, 2018, Oak Park River Forest had $325.5 million in assets, including $253.6 million of loans and $292.6 million of total deposits. We believe the acquisition will enhance our position in an attractive Chicago metropolitan market, while also providing an important source of low-cost deposits. We believe the synergies from this combination will further enhance the value of the Byline franchise. Completion of the transaction is subject to regulatory approval, the effectiveness of a registration statement to be filed with the Securities and Exchange Commission (“SEC”), the approval of Oak Park River Forest’s stockholders, and other customary closing conditions. We expect the acquisition to close during the first half of 2019.

~~During 2015 and 2016, we performed a~~We continually perform strategic ~~review~~reviews of our existing ~~core~~ banking footprint. With technology improvements and changes to customers’ banking preferences, we ~~examined~~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 ~~the Recapitalization,~~our recapitalization, our branch network has been reduced from 88 to ~~57.~~59, including the additional nine branches added through the First Evanston acquisition. During June 2018, we consolidated six branches and two other facilities within our current network that had a minimal impact on our customer service levels, convenience, and business development capabilities. We will continue to strategically evaluate our locations based on our growth and profitability standards.

On June 29, 2017, we commenced our initial public offering (the “IPO”) whereby we sold 4,630,194 shares of our common stock at a price to the public of $19.00 per share, resulting in net proceeds to us of $76.8 million after deducting offering related commissions and expenses. In addition, certain selling stockholders participated in the offering and sold an aggregate of 1,924,806 shares of our common stock at the same price per share. Our common stock is currently traded on the New York Stock Exchange under the symbol “BY”. We believe that the capital raised through our IPO will allow us to continue to grow our franchise and increase our market share among small businesses and middle-market companies in the markets we serve.

Our accounting and reporting policies conform to ~~GAAP~~accounting principles generally accepted in the United States (“GAAP”) and conform to general practices within the industry in which we operate. 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. These estimates, assumptions and judgements are based on information available as of the date of the financial statements and, 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~~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 (“OTTI”)~~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 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 ~~Byline’s~~our audited Consolidated Financial Statements, ~~as of December 31, 2016 and 2015,~~ included in our ~~prospectus in connection with our initial public offering~~Annual Report on Form 10-K that we filed with the SEC on ~~July 3, 2017.~~
March 30, 2018.

We account for business combinations under the acquisition method of accounting in accordance with ASC ~~Topic~~ 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 ~~Topic~~ 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.

Our accounting methods for loans and leases differ depending on whether ~~the loans and leases~~they are new ~~loans and leases,~~ 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.

We account for originated loans and leases and purchased loans and leases not acquired through business combinations as originated ~~loans.~~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.

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.~~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, ~~and~~which is 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 ~~and lease~~ losses.

For acquired ~~non-impaired~~non‑impaired loans and leases, the excess or deficit of the loan orand 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.

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 date 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 ~~it is~~ decreased by ~~charge-offs,~~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~~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 ~~non-impaired~~ 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~~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~~non‑impaired loans and originated loans of ~~$250,000~~$100,000 or greater with an internal risk rating of substandard or below and on ~~non-accrual,~~nonaccrual, as well as loans classified as ~~TDR,~~troubled debt restructurings (“TDR”), are reviewed individually for impairment on a quarterly basis.

Goodwill represents the excess of the purchase consideration over the fair value of net assets acquired in connection with ~~the Recapitalization~~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 ~~Topic~~ 350”).

Impairment testing is performed ~~by comparing the carrying value of~~using either a qualitative or quantitative approach at the reporting unit ~~with the fair value of 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 are recognized separately when they are acquired through sales of loans or when the rights to service loans are purchased. When loans are sold, servicing assets are recorded at fair value in accordance with ASC Topic 860, Transfers and Servicing (“ASC ~~Topic~~ 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, ~~2017,~~2018, included in this report, for additional information.

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 assets are amortized over the revised remaining useful life. Core deposit intangibles are currently amortized over an approximate ten year period.

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 ~~ten~~12 year period.

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, ~~as of December 31, 2016 and 2015,~~ included in our ~~prospectus in connection with our initial public offering that we filed with~~Annual Report on Form 10-K for the ~~SEC on July 3,~~year ended December 31, 2017, for a complete discussion of our use of fair value of financial assets and liabilities and their related measurement practices.

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~~charge‑offs in the allowance for loan and lease losses. Positive adjustments, if any, at the time of foreclosure or repossession are recognized ~~as a reduction,~~ in ~~non-interest~~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~~write‑downs are recorded as a decrease in the asset and charged against other real estate owned valuation adjustments. Operating expenses of such properties, net of related income, are included in ~~non-interest~~non‑interest expense, and gains and losses on their disposition are included in ~~non-interest~~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~~,360‑20, Real Estate Sales (“ASC ~~Topic 360-20”~~360‑20”). Any losses on the sales of other real estate owned properties are recognized immediately.

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 toagainst 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 non-interest expense.

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 ~~its~~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~~long‑range business forecasts to provide additional information for ~~our~~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~~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 ~~Byline’s~~our Consolidated Financial Statements, ~~as of December 31, 2016 and 2015,~~ included in our ~~prospectus in connection with our initial public offering that we filed with~~Annual Report on Form 10-K for the ~~SEC on July 3,~~year ended December 31, 2017, for further information on income taxes.

Refer to Note 2 of our Interim Unaudited Condensed Consolidated Financial Statements as of September 30, ~~2017,~~2018, 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.

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~~non‑impaired and acquired impaired loans.

These factors and metrics described in this ~~report~~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 ~~the Recapitalization.~~our recapitalization.

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 and leases, 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, servicing fees, 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 ~~2017~~2018 results reflect healthy growth in net interest income, primarily driven by the ~~positive impact~~First Evanston acquisition and continued growth in organic loan and lease originations. Net interest margin increased to 4.73% for the third quarter of ~~our efforts over~~2018, compared to 4.18% for the ~~past year~~third quarter of 2017. The increase was primarily due to ~~continue~~increased interest income due to ~~drive revenue growth~~an increase in earning assets as a result of the acquisition, and ~~improve efficiencies. Compared~~an increase in interest rates on variable rate loans during the quarter. Our total revenues increased by $20.4 million, or 47.1%, compared to the third quarter of ~~2016, our total revenues~~2017, primarily driven by a full quarter of the inclusion of the First Evanston loan portfolio, loan and lease originations, and increased ~~by more than 65% while our efficiency ratio improved to 69.92% from 84.38%. As a result, we were able to deliver a 523.4% year-over-year increase in net income.~~loan and lease yields.

During the second quarter of 2017, and in connection with our initial public offering, we agreed to repurchase all $15.0 million of our outstanding shares of Series A Preferred Stock for $25.5 million. The $10.5 million excess of consideration paid over the $15.0 million carrying amount of the Series A Preferred Stock was treated as a one-time dividend declaration on the Series A Preferred Stock. Both the dividend declared on the Series A Preferred Stock and the regular quarterly dividends paid on our Series B Preferred Stock are reflected in the reported net income available to common stockholders for the nine months ended September 30, 2017, which was $11.4 million or $0.43 per basic and diluted common ~~share.

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 ~~the Recapitalization~~our recapitalization and the ~~acquisition~~acquisitions of Ridgestone and First Evanston, 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 ~~evidence of credit deterioration~~a discount at acquisition represent a meaningful portion of our interest-earning assets. As of September 30, ~~2017,~~2018, acquired loans with evidence of credit deterioration accounted for under ASC Topic 310-30, Accounting for Purchased Loans with Deteriorated Credit Quality,, represented ~~15.4%~~8.5% of our total loan portfolio.

Changes in the market interest rates and 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 ~~tables present,~~table presents, for the periods indicated, 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 thousands).

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 with 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 nine months ended September 30, ~~2017~~2018 was ~~$90.8~~$125.3 million compared to ~~$62.4~~$90.8 million during the same period in ~~2016,~~2017, an increase of ~~$28.4~~$34.6 million, or ~~45.5%~~ 38.1%. The increase in interest income of ~~$33.2~~$43.2 million was primarily a result of ~~organic~~loan growth as a result of the First Evanston acquisition, organic loan and lease ~~portfolio~~originations, an increase in average yield on loans and ~~the Ridgestone acquisition.~~leases, and an increase in average yield on securities available-for-sale. Interest expense increased by ~~$4.9~~$8.6 million for the nine months ended September 30, ~~2017~~2018 compared to the nine months ended September 30, ~~2016,~~2017, primarily due to ~~additional FHLB advances~~an increase in average yield on interest-bearing deposits and ~~acquired time deposits, partially offset by fair value adjustments on time deposits~~deposit growth as a result of ~~the Ridgestone acquisition.~~acquired time deposits.

Net loan accretion income was $8.3 million for the three months ended September 30, 2018 compared to $2.2 million for the three months ended September 30, ~~2017 compared to $1.2~~2017. Net loan accretion income was $14.2 million for the ~~three~~nine months ended September 30, ~~2016. Net loan accretion income was~~2018 compared to $6.3 million for the nine months ended September 30, ~~2017~~2017. Total net loan accretion on acquired loans contributed 74 basis points to the net interest margin for the three months ended September 30, 2018, compared to ~~$1.5 million~~29 basis points for the three months ended September 30, 2017. Total net loan accretion on acquired loans contributed 52 basis points to the net interest margin for the nine months ended September 30, ~~2016.~~2018, compared to 28 basis points for the nine months ended September 30, 2017.

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 totaled ~~$3.9~~$5.8 million and ~~$1.7~~$3.9 million for the three months ended September 30, 2018 and 2017, ~~and 2016, respectively.~~respectively, an increase of $1.9 million. Provisions for loan and lease losses totaled ~~$9.3~~$14.9 million and ~~$5.3~~$9.3 million for the nine months ended September 30, 2018 and 2017, ~~and 2016, respectively.~~respectively, an increase of $5.6 million. These increases ~~reflect~~were mainly due to an increase in a specific reserve on a commercial loan relationship during the first quarter of 2018, additional specific impairment in the unguaranteed portion of the government guaranteed portfolio, and an increase to the general reserve driven by growth in the originated loan and lease portfolio during the periods as well as net impairment of certain acquired loans based on a periodic update of expected loan cash flows, which resulted in a reclassification of $6.9 million and $24.3 million from non-accretable to accretable yield that can be recognized over the life of the portfolio for the three and nine months ended September 30, 2017, respectively.portfolio.

We reported non-interest income of ~~$11.9~~$11.1 million and ~~$4.8~~$11.9 million for the three months ended September 30, ~~2017~~2018 and ~~2016,~~2017, respectively. The ~~increase~~decrease of ~~$7.1 million~~$775,000 was primarily due to a decrease in gains on sales of government guaranteed loans through our Small Business Capital operations of $2.5 million for the three months ended September 30, 2018 compared to the same period in 2017. The gains on sale of loans were $5.0 million for the three months ended September 30, 2018, compared to $7.5 million for the three months ended September 30, 2017. The decrease is also attributed to a decrease in net servicing fees of $783,000 for the three months ended September 30, 2018, primarily due to a change in fair value of the servicing asset as a result of increases in prepayment speed and discount rate assumptions on government guaranteed loans. These decreases were partially offset by an increase in other non-interest income of $1.1 million, primarily due to an increase in customer derivative products fee income and a net gain on sale of an asset held for sale for the three months ended September 30, 2018.

We reported non-interest income of $37.1 million and $37.4 million for the nine months ended September 30, 2018 and 2017, respectively. The decrease of $346,000 was primarily due to decreased gains on sales of government guaranteed loans through our Small Business Capital operation, ~~of $7.5 million. There~~which were no gains on sales of government guaranteed loans during the three months ended September 30, 2016. This was partially offset by a decrease in gains on sales of securities available-for-sale of $802,000 during the three months ended September 30, 2016.

~~We reported non-interest income of $37.4~~$22.2 million and ~~$15.3~~$24.0 million for the nine months ended September 30, 2017 and 2016, respectively. The increase of $22.1 million was primarily due to gains on sales of government guaranteed loans through our Small Business Capital operation of $24.0 million.

While portions of the loans that we originate are sold and generate gain on sale revenue, servicing rights for the majority of loans that we sell are retained by Byline Bank. In exchange for continuing to service loans that have been sold, Byline Bank receives a servicing fee paid from a portion of the interest cash flow of the loan. ~~As a result of the Ridgestone acquisition, we received $959,000~~We generated $176,000 in net servicing fees on the sold portion of the government guaranteed portfolio for the three months ended September 30, 2018, compared to $959,000 for the three months ended September 30, 2017, ~~and $3.0~~a decrease of $783,000.

~~We had~~ATM and interchange fee income increased by $286,000 for the three months ended September 30, 2018 compared to the three months ended September 30, 2017, primarily driven by increased interchange fees resulting from a credit card vendor agreement signing bonus. ATM and interchange fees decreased $202,000 for the nine months ended September 30, 2018 compared to the nine months ended September 30, 2017, primarily driven by a revision to our fee assessment schedule.

Net gains on sales of loans decreased by $2.5 million for the three months ended September 30, 2018 compared to the three months ended September 30, 2017. We sold $59.6 million of government guaranteed loans for the three months ended September 30, 2018 compared to $71.8 million for the three months ended September 30, 2017.

~~Non-interest~~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 our Consolidated Financial Statements, included in our Annual Report on Form 10-K for the year ended December 31, 2017, for further information on income taxes.

Refer to Note 2 of our Interim Unaudited Condensed Consolidated Financial Statements as of September 30, 2018, 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.

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.

Our third quarter 2018 results reflect healthy growth in net interest income, primarily driven by the First Evanston acquisition and continued growth in organic loan and lease originations. Net interest margin increased to 4.73% for the third quarter of 2018, compared to 4.18% for the third quarter of 2017. The increase was primarily due to increased interest income due to an increase in earning assets as a result of the acquisition, and an increase in interest rates on variable rate loans during the quarter. Our total revenues increased by $20.4 million, or 47.1%, compared to the third quarter of 2017, primarily driven by a full quarter of the inclusion of the First Evanston loan portfolio, loan and lease originations, and increased loan and lease yields.

We reported consolidated net income for the three months ended September 30, ~~2017 was $31.1~~2018 of $14.5 million compared to ~~$22.4 million for the three months ended September 30, 2016, an increase~~net income of $8.7 million or 38.8%. Non-interest expense for the nine months ended September 30, 2017 was $89.2 million compared to $69.7 million for the nine months ended September 30, 2016, an increase of $19.5 million or 28.0%. These increases are primarily due to the additional expenses as a result of the acquisition of Ridgestone.

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

~~Salaries and employee benefits, the single largest component of our non-interest expense, totaled $16.3~~$9.8 million for the three months ended September 30, 2017, an increase of ~~$5.0~~$4.8 million. The increase in net income was primarily attributable to a $21.2 million ~~compared to~~increase in net interest income, offset by a $6.9 million increase in non-interest expense, a $6.8 million increase in provision for income taxes, a $1.9 million increase in provision for loan and lease losses, and a $775,000 decrease in non-interest income. The increase in net interest income during the three months ended September 30, ~~2016. Salaries~~2018 was a result of the First Evanston acquisition, organic loan growth, and recent rate increases, slightly offset by increased interest-bearing deposit yields during the current quarter. The increase in non-interest expense was primarily due to an increase in salaries and employee benefits ~~totaled $50.2~~of $5.0 million due to organizational growth as a result of the First Evanston acquisition, an increase in legal, audit and other professional fees of $750,000 partially due to merger related expenses, and an increase in data processing of $325,000 partially due to expenses regarding the upcoming core system conversion. The increase in provision for income taxes was primarily driven by an increase in net income during the quarter. The increase in provision for loan and lease losses was mainly due to credit deterioration in the government guaranteed portfolio and increases to the general reserve driven by new loan and lease originations. The decrease in non-interest income was driven by decreased volume of loan sales during the quarter.

Net income available to common stockholders was $14.3 million or $0.40 per basic common share and $0.39 per diluted common share for the three months ended September 30, 2018, compared to a $9.6 million net income or $0.33 per basic common share and $0.32 per diluted common share for the three months ended September 30, 2017. Dividends on preferred shares were $196,000 for the three months ended September 30, 2018 compared to $195,000 for the three months ended September 30, 2017.

We reported consolidated net income for the nine months ended September 30, 2018 of $24.1 million compared to net income of $22.5 million for the nine months ended September 30, 2017, an increase of ~~$16.0~~$1.6 million. The increase in net income was primarily attributable to a $34.6 million increase in net interest income, offset by a $26.5 million increase in non-interest expense, a $5.6 million increase in provision for loan and lease losses, a $539,000 increase in provision for income taxes, and a $346,000 decrease in non-interest income. The increase in net interest income during the nine months ended September 30, 2018 was a result of the First Evanston acquisition, organic loan growth, and recent rate increases, slightly offset by increased interest-bearing deposits yields during the current period. The increase in non-interest expense was primarily due to an increase in salaries and employee benefits of $8.7 million due to organizational growth as a result of the First Evanston acquisition, an increase in data processing of $8.1 million due to expenses incurred related to the upcoming core system conversion, and an increase in legal, audit and other professional fees of $4.3 million partially due to acquisition related expenses. The increase in provision for loan and lease losses was primarily driven by new loan and lease originations. The increase in provision for income taxes was primarily driven by an increase in net income during the period. The decrease in non-interest income was primarily driven by decreased volume of loan sales and a change in fair value of the servicing asset for the current period.

Net income available to common stockholders was $23.5 million or $0.73 per basic and $0.71 per diluted common share for the nine months ended September 30, 2018, compared to $11.4 million or $0.43 per basic and diluted common share for the nine months ended September 30, 2017. Dividends on preferred shares were $587,000 for the nine months ended September 30, 2018 compared to $11.1 million for the nine months ended September 30, 2017.

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

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 and First Evanston, 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, 2018, acquired loans with evidence of credit deterioration accounted for under ASC Topic 310-30, Accounting for Purchased Loans with Deteriorated Credit Quality, represented 8.5% of our total loan portfolio.

The following table presents, for the periods indicated, 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 thousands).

Net interest income for the three months ended September 30, 2018 was $52.6 million compared to $31.4 million during the same period in 2017, an increase of $21.2 million, or 67.4%. The increase in interest income of $26.0 million was primarily a result of loans and securities assumed as a result of the First Evanston acquisition and an increase in average yield on loans and leases. Interest expense increased by $4.8 million for the three months ended September 30, 2018 compared to the three months ended September 30, 2017, primarily due to deposits assumed as a result of the acquisition, an increase in time deposits and money market demand deposits driven by continued promotional campaigns during the quarter, and a slight increase in average yield on interest-bearing deposits due to increased interest rates.

Net interest income for the nine months ended September 30, 2018 was $125.3 million compared to $90.8 million during the same period in 2017, an increase of $34.6 million, or 38.1%. The increase in interest income of $43.2 million was primarily a result of loan growth as a result of the First Evanston acquisition, organic loan and lease originations, an increase in average yield on loans and leases, and an increase in average yield on securities available-for-sale. Interest expense increased by $8.6 million for the nine months ended September 30, 2018 compared to the nine months ended September 30, ~~2016. These increases are~~2017, primarily due to an ~~addition~~increase in ~~the number of employees~~average yield on interest-bearing deposits and deposit growth as a result of acquired time deposits.

The net interest margin for the ~~Ridgestone acquisition. Our staffing increased from 682 full-time equivalent employees as of~~three months ended September 30, ~~2016~~2018 was 4.73%, an increase of 55 basis points compared to ~~824 as of~~4.18% for the three months ended September 30, 2017.

~~Occupancy expense increased $14,000~~The net interest margin for the nine months ended September 30, 2018 was 4.56%, an increase of 49 basis points compared to 4.07% for the nine months ended September 30, 2017. The primary driver of the increases for the three and nine month periods was an increase in average loan and lease yields and an increase in loan accretion income, partially offset by an increase in average interest-bearing deposit yields. Net loan accretion income was $8.3 million for the three months ended September 30, 2018 compared to $2.2 million for the three months ended September 30, 2017. Net loan accretion income was $14.2 million for the nine months ended September 30, 2018 compared to $6.3 million for the nine months ended September 30, 2017. Total net loan accretion on acquired loans contributed 74 basis points to the net interest margin for the three months ended September 30, 2018, compared to 29 basis points for the three months ended September 30, 2017. Total net loan accretion on acquired loans contributed 52 basis points to the net interest margin for the nine months ended September 30, 2018, compared to 28 basis points for the nine months ended September 30, 2017.

Provisions for loan and lease losses totaled $5.8 million and $3.9 million for the three months ended September 30, 2018 and 2017, respectively, an increase of $1.9 million. Provisions for loan and lease losses totaled $14.9 million and $9.3 million for the nine months ended September 30, 2018 and 2017, respectively, an increase of $5.6 million. These increases were mainly due to an increase in a specific reserve on a commercial loan relationship during the first quarter of 2018, additional specific impairment in the unguaranteed portion of the government guaranteed portfolio, and an increase to the general reserve driven by growth in the originated loan and lease portfolio.

The ALLL as a percentage of loans and leases, net of acquisition accounting adjustments, decreased from 0.73% at December 31, 2017, to 0.68% at September 30, 2018. The decrease was primarily due to an increase in the loan portfolio from the First Evanston acquisition, which has been adjusted to fair value under ASC Topic 805, Business Combinations.

We reported non-interest income of $11.1 million and $11.9 million for the three months ended September 30, 2018 and 2017, respectively. The decrease of $775,000 was primarily due to a decrease in gains on sales of government guaranteed loans through our Small Business Capital operations of $2.5 million for the three months ended September 30, 2018 compared to the same period in ~~2016~~2017. The gains on sale of loans were $5.0 million for the three months ended September 30, 2018, compared to $7.5 million for the three months ended September 30, 2017. The decrease is also attributed to a decrease in net servicing fees of $783,000 for the three months ended September 30, 2018, primarily due to a change in fair value of the servicing asset as a result of increases in prepayment speed and discount rate assumptions on government guaranteed loans. These decreases were partially offset by an increase in other non-interest income of $1.1 million, primarily due to an increase in customer derivative products fee income and a net gain on sale of an asset held for sale for the three months ended September 30, 2018.

We reported non-interest income of $37.1 million and $37.4 million for the nine months ended September 30, 2018 and 2017, respectively. The decrease of $346,000 was primarily due to decreased ~~$57,000~~gains on sales of government guaranteed loans through our Small Business Capital operation, which were $22.2 million and $24.0 million during the nine months ended September 30, 2018 and 2017, respectively, and a decrease in net servicing fees of $1.8 million compared to the nine months ended September 30, 2017. These decreases were partially offset by an increase in other non-interest income of $2.0 million primarily due to an increase in customer derivative products fee income.

Service charges and fees represent fees 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 fees. Fees and service charges on deposits increased $407,000 for the three months ended September 30, 2018 compared to the same period in 2017. Fees and service charges on deposits increased $608,000 for the nine months ended September 30, 2018 compared to the same period in 2017. The increases were primarily driven by additional deposit accounts from the First Evanston acquisition.

~~strategy in which we consolidated 28 branches during 2016, partially offset by increased expenses as a result of the Ridgestone acquisition.~~

Equipment expense for three months ended September 30, 2017 was $630,000 compared to $516,000 for the three months ended September 30, 2016, an increase of $114,000. Equipment expense for the nine months ended September 30, 2017 was$783,000. Net servicing fees decreased $1.8 ~~million compared to $1.5~~ million for the nine months ended September 30, ~~2016, an increase~~2018 compared to the nine months ended September 30, 2017. The decreases were primarily driven by the change in fair value of ~~$290,000. These increases are primarily due~~the servicing asset as a result of changes to valuation assumptions on government guaranteed loans based on the higher interest rate environment.

ATM and interchange fee income increased ~~depreciation expense related to increased investment in equipment and technology assets.~~

~~Loan and lease related expenses~~by $286,000 for the three months ended September 30, ~~2017 were $891,000~~2018 compared to ~~$443,000~~the three months ended September 30, 2017, primarily driven by increased interchange fees resulting from a credit card vendor agreement signing bonus. ATM and interchange fees decreased $202,000 for the nine months ended September 30, 2018 compared to the nine months ended September 30, 2017, primarily driven by a revision to our fee assessment schedule.

There were no sales of securities during the three months ended September 30, 2018 and 2017. Gains on sales of securities during the nine months ended September 30, 2018 were $4,000 compared to $8,000 for the nine months ended September 30, 2017.

Net gains on sales of loans decreased by $2.5 million for the three months ended September 30, ~~2016, an increase of $448,000. Loan and lease related expenses for~~2018 compared to the ~~nine~~three months ended September 30, ~~2017 were $2.6~~2017. We sold $59.6 million of government guaranteed loans for the three months ended September 30, 2018 compared to ~~$1.1~~$71.8 million for the three months ended September 30, 2017. Net gains on sales of loans decreased $1.8 million for the nine months ended September 30, ~~2016, an increase of $1.5 million. These increases are primarily due~~2018 compared to the ~~increased lending activity resulting from our Small Business Capital operations, partially offset by lower loan real estate tax expense for problem loans.~~

~~Legal, audit and other professional fees for the three~~nine months ended September 30, ~~2017 were $1.6~~2017. We sold $233.1 million ~~compared to $1.1 million for the three months ended September 30, 2016, an increase~~ of ~~$543,000 or 50.9%. Legal, audit and other professional fees~~government guaranteed loans for the nine months ended September 30, ~~2017 were $4.4 million~~2018 compared to ~~$3.8~~$223.4 million for the nine months ended September 30, ~~2016, an increase of $584,000. These increases are~~2017. The decrease in net gains on sales was primarily driven by ~~increased legal~~a decrease in average premiums.

Wealth management and ~~professional~~trust income represents fees ~~related~~charged to ~~our costs associated with becoming a public company at the end of the second quarter of 2017.~~

~~Data processing expense~~customers for investment, trust, or wealth management services and are primarily determined by total assets under management. Wealth management and trust income was $674,000 for the three months ended September 30, ~~2017 was $2.4 million compared to $2.0 million for the three months ended September 30, 2016, an increase of $409,000, or 20.6%,~~2018 and ~~was $7.3 million~~$866,000 for the nine months ended September 30, ~~2017 compared to $5.8 million for the same period during 2016. These increases are primarily due to increased data processing expenses related~~2018. Prior to the ~~Ridgestone acquisition.~~

~~Net loss recognized on other real estate owned and other related expenses~~First Evanston acquisition in the second quarter of 2018, we did not offer these services. Assets under management were ~~$565,000 for the three months ended~~$648.5 million as of September 30, 2017, an increase of $273,000 compared to the same period in 2016. The increase is primarily due to lower gains on sales of other real estate owned properties, partially offset by lower write-downs of values, subsequent to transfer to OREO. Net loss recognized on other real estate owned and other related expenses for the nine months ended September 30, 2017 were $136,000 compared to OREO expense of $1.4 million for the nine months ended September 30, 2016. This decrease in net loss recognized on other real estate owned and other related expenses was primarily attributed to reduced OREO related expenses and an increase in gains on sales of other real estate owned.2018.

Regulatory assessments for the three months ended September 30, 2017 were $326,000 compared to $502,000 for the same period in 2016, a decrease of $176,000 or 34.9%. Regulatory assessments for the nine months ended September 30, 2017 were $894,000 compared to $1.9 million for the same period in 2016, a decrease of $1.0 million or 53.7%. These decreases are primarily due to our improved risk profile as a result of improved capital ratios, performance and asset quality.

Advertising and promotions for the three months ended September 30, 2017 were $196,000 compared to $156,000 for same period in 2016, an increase of $40,000 and were $803,000 for the nine months ended September 30, 2017 compared to $454,000 for the same period in 2016, an increase of $349,000, primarily due to increased advertising and promotions, attributable to our Small Business Capital operations.

Telecommunications expense was $351,000 for the three months ended September 30, 2017 compared to $370,000 for the three months ended September 30, 2016, a decrease of $19,000. Telecommunications expense was $1.2 million for the nine months ended September 30, 2017, a decrease of $119,000 or 9.2% compared to the same period in 2016. These decreases are a result of our ongoing cost savings initiatives.

Other non-interest ~~expense for the three months ended September 30, 2017~~income was ~~$3.7 million compared to~~ $1.7 million for the three months ended September 30, ~~2016, an increase of $2.0 million. During the third quarter of 2017, we incurred impairment charges on assets held for sale of $951,000, primarily related~~2018 compared to ~~the planned disposition of the former headquarters of Byline Bank. Our provision for unfunded commitments was $299,000~~$547,000 for the three months ended September 30, ~~2017 compared to~~2017. The primary drivers of the increase were an increase in gains on sales of assets held for sale of $741,000 resulting from the sale of a ~~benefit~~former branch property and an increase in customer derivative products fee income of ~~$14,000 for the three months ended September 30, 2016.

Other non-interest ~~expense~~income was ~~$7.2~~$4.1 million compared to $2.1 million for the nine months ended September 30, 2018 and 2017, ~~compared~~respectively. The primary drivers of the increase were an increase in customer derivative products fee income of $958,000 due to ~~$5.5 million for~~additional customer swaps executed during the ~~same period~~first and second quarters and an increase in ~~2016. In addition to incurring impairment charges~~gains on sales of assets held for sale travel and entertainment related expenses increased $368,000 to $786,000 for the nine months ended September 30, 2017, over the comparable period in 2016, primarily attributable to our Small Business Capital operations. Our provision for unfunded commitments was $272,000 for the nine months ended September 30, 2017 compared to $56,000 for the nine months ended September 30, 2016, an increase of ~~$216,000, primarily due to growth in our unfunded loan and lease commitments.~~

Our efficiency ratio was 69.92% for the three months ended September 30, 2017, compared to 84.38% for the three months ended September 30, 2016. Our efficiency ratio was 67.76% for the nine months ended September 30, 2017, compared to 86.88% for the comparable period in 2016. The improvement in our efficiency ratio is primarily attributable to increased revenues$741,000 resulting from ~~our acquisition~~the sale of ~~Ridgestone and~~a former branch property, partially offset by a $313,000 decrease in gain on death benefit for bank owned life insurance regarding a gain recorded in the ~~continued organic growth~~second quarter of ~~our loan and lease portfolios over the last 12 months.~~2017.

We ~~recorded~~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 our Consolidated Financial Statements, included in our Annual Report on Form 10-K for the year ended December 31, 2017, for further information on income taxes.

Refer to Note 2 of our Interim Unaudited Condensed Consolidated Financial Statements as of September 30, 2018, included in this report, for a ~~benefit~~description of recent accounting pronouncements, including the effective dates of adoption and anticipated effects on our results of operations and financial condition.

We reported consolidated net income for the three months ended September 30, 2018 of $14.5 million compared to net income of $9.8 million for the three months ended September 30, 2017, an increase of $4.8 million. The increase in net income was primarily attributable to a $21.2 million increase in net interest income, offset by a $6.9 million increase in non-interest expense, a $6.8 million increase in provision for income taxes, a $1.9 million increase in provision for loan and lease losses, and a $775,000 decrease in non-interest income. The increase in net interest income during the three months ended September 30, 2018 was a result of the First Evanston acquisition, organic loan growth, and recent rate increases, slightly offset by increased interest-bearing deposit yields during the current quarter. The increase in non-interest expense was primarily due to an increase in salaries and employee benefits of $5.0 million due to organizational growth as a result of the First Evanston acquisition, an increase in legal, audit and other professional fees of $750,000 partially due to merger related expenses, and an increase in data processing of $325,000 partially due to expenses regarding the upcoming core system conversion. The increase in provision for income taxes was primarily driven by an increase in net income during the quarter. The increase in provision for loan and lease losses was mainly due to credit deterioration in the government guaranteed portfolio and increases to the general reserve driven by new loan and lease originations. The decrease in non-interest income was driven by decreased volume of loan sales during the quarter.

We reported consolidated net income for the nine months ended September 30, 2018 of $24.1 million compared to net income of $22.5 million for the nine months ended September 30, 2017, an increase of $1.6 million. The increase in net income was primarily attributable to a $34.6 million increase in net interest income, offset by a $26.5 million increase in non-interest expense, a $5.6 million increase in provision for loan and lease losses, a $539,000 increase in provision for income taxes, and a $346,000 decrease in non-interest income. The increase in net interest income during the nine months ended September 30, 2018 was a result of the First Evanston acquisition, organic loan growth, and recent rate increases, slightly offset by increased interest-bearing deposits yields during the current period. The increase in non-interest expense was primarily due to an increase in salaries and employee benefits of $8.7 million due to organizational growth as a result of the First Evanston acquisition, an increase in data processing of $8.1 million due to expenses incurred related to the upcoming core system conversion, and an increase in legal, audit and other professional fees of $4.3 million partially due to acquisition related expenses. The increase in provision for loan and lease losses was primarily driven by new loan and lease originations. The increase in provision for income taxes was primarily driven by an increase in net income during the period. The decrease in non-interest income was primarily driven by decreased volume of loan sales and a change in fair value of the servicing asset for the current period.

Net interest income for the nine months ended September 30, 2018 was $125.3 million compared to $90.8 million during the same period in 2017, an increase of $34.6 million, or 38.1%. The increase in interest income of $43.2 million was primarily a result of loan growth as a result of the First Evanston acquisition, organic loan and lease originations, an increase in average yield on loans and leases, and an increase in average yield on securities available-for-sale. Interest expense increased by $8.6 million for the nine months ended September 30, 2018 compared to the nine months ended September 30, 2017, primarily due to an increase in average yield on interest-bearing deposits and deposit growth as a result of acquired time deposits.

The net interest margin for the three months ended September 30, 2018 was 4.73%, an increase of 55 basis points compared to 4.18% for the three months ended September 30, 2017. The net interest margin for the nine months ended September 30, 2018 was 4.56%, an increase of 49 basis points compared to 4.07% for the nine months ended September 30, 2017. The primary driver of the increases for the three and nine month periods was an increase in average loan and lease yields and an increase in loan accretion income, partially offset by an increase in average interest-bearing deposit yields. Net loan accretion income was $8.3 million for the three months ended September 30, 2018 compared to $2.2 million for the three months ended September 30, 2017. Net loan accretion income was $14.2 million for the nine months ended September 30, 2018 compared to $6.3 million for the nine months ended September 30, 2017. Total net loan accretion on acquired loans contributed 74 basis points to the net interest margin for the three months ended September 30, 2018, compared to 29 basis points for the three months ended September 30, 2017. Total net loan accretion on acquired loans contributed 52 basis points to the net interest margin for the nine months ended September 30, 2018, compared to 28 basis points for the nine months ended September 30, 2017.

We reported non-interest income of $11.1 million and $11.9 million for the three months ended September 30, 2018 and 2017, respectively. The decrease of $775,000 was primarily due to a decrease in gains on sales of government guaranteed loans through our Small Business Capital operations of $2.5 million for the three months ended September 30, 2018 compared to the same period in 2017. The gains on sale of loans were $5.0 million for the three months ended September 30, 2018, compared to $7.5 million for the three months ended September 30, 2017. The decrease is also attributed to a decrease in net servicing fees of $783,000 for the three months ended September 30, 2018, primarily due to a change in fair value of the servicing asset as a result of increases in prepayment speed and discount rate assumptions on government guaranteed loans. These decreases were partially offset by an increase in other non-interest income of $1.1 million, primarily due to an increase in customer derivative products fee income and a net gain on sale of an asset held for sale for the three months ended September 30, 2018.

We reported non-interest income of $37.1 million and $37.4 million for the nine months ended September 30, 2018 and 2017, respectively. The decrease of $346,000 was primarily due to decreased gains on sales of government guaranteed loans through our Small Business Capital operation, which were $22.2 million and $24.0 million during the nine months ended September 30, 2018 and 2017, respectively, and a decrease in net servicing fees of $1.8 million compared to the nine months ended September 30, 2017. These decreases were partially offset by an increase in other non-interest income of $2.0 million primarily due to an increase in customer derivative products fee income.

Service charges and fees represent fees 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 fees. Fees and service charges on deposits increased $407,000 for the three months ended September 30, 2018 compared to the same period in 2017. Fees and service charges on deposits increased $608,000 for the nine months ended September 30, 2018 compared to the same period in 2017. The increases were primarily driven by additional deposit accounts from the First Evanston acquisition.

While portions of the loans that we originate are sold and generate gain on sale revenue, servicing rights for the majority of loans that we sell are retained by Byline Bank. In exchange for continuing to service loans that have been sold, Byline Bank receives a servicing fee paid from a portion of the interest cash flow of the loan. We generated $176,000 in net servicing fees on the sold portion of the government guaranteed portfolio for the three months ended September 30, 2018, compared to $959,000 for the three months ended September 30, 2017, a decrease of $783,000. Net servicing fees decreased $1.8 million for the nine months ended September 30, 2018 compared to the nine months ended September 30, 2017. The decreases were primarily driven by the change in fair value of the servicing asset as a result of changes to valuation assumptions on government guaranteed loans based on the higher interest rate environment.

ATM and interchange fee income increased by $286,000 for the three months ended September 30, 2018 compared to the three months ended September 30, 2017, primarily driven by increased interchange fees resulting from a credit card vendor agreement signing bonus. ATM and interchange fees decreased $202,000 for the nine months ended September 30, 2018 compared to the nine months ended September 30, 2017, primarily driven by a revision to our fee assessment schedule.

Net gains on sales of loans decreased by $2.5 million for the three months ended September 30, 2018 compared to the three months ended September 30, 2017. We sold $59.6 million of government guaranteed loans for the three months ended September 30, 2018 compared to $71.8 million for the three months ended September 30, 2017. Net gains on sales of loans decreased $1.8 million for the nine months ended September 30, 2018 compared to the nine months ended September 30, 2017. We sold $233.1 million of government guaranteed loans for the nine months ended September 30, 2018 compared to $223.4 million for the nine months ended September 30, 2017. The decrease in net gains on sales was primarily driven by a decrease in average premiums.

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 $674,000 for the three months ended September 30, 2018 and $866,000 for the nine months ended September 30, 2018. Prior to the First Evanston acquisition in the second quarter of 2018, we did not offer these services. Assets under management were $648.5 million as of September 30, 2018.

Other non-interest income was $1.7 million for the three months ended September 30, 2018 compared to $547,000 for the three months ended September 30, 2017. The primary drivers of the increase were an increase in gains on sales of assets held for sale of $741,000 resulting from the sale of a former branch property and an increase in customer derivative products fee income of $190,000 due to additional customer swaps executed during the first and second quarters.

Non-interest expense for the three months ended September 30, 2018 was $38.0 million compared to $31.1 million for the three months ended September 30, 2017, an increase of $6.9 million or 22.2%. Non-interest expense for the nine months ended September 30, 2018 was $115.6 million compared to $89.2 million for the nine months ended September 30, 2017, an increase of $26.5 million or 29.7%.

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

Salaries and employee benefits, the single largest component of our non-interest expense, totaled $21.3 million for the three months ended September 30, 2018 compared to $16.3 million for the three months ended September 30, 2017, an increase of $5.0 million or 30.6%. Salaries and employee benefits totaled $58.8 million for the nine months ended September 30, 2018, an increase of $8.7 million compared to the nine months ended September 30, 2017. The increases were primarily a result of the First Evanston acquisition. Our staffing increased from 824 full-time equivalent employees as of September 30, 2017 to 924 as of September 30, 2018.

Occupancy expense for the three months ended September 30, 2018 was $3.5 million compared to $3.3 million for the three months ended September 30, 2017, an increase of $247,000 or 7.5%. Occupancy expense increased $1.3 million for the nine months ended September 30, 2018 compared to the nine months ended September 30, 2017. These increases were primarily a result of our larger branch network.

Equipment expense for three months ended September 30, 2018 was $617,000 compared to $630,000 for the three months ended September 30, 2017, a decrease of $13,000 or 2.1%. Equipment expense for the nine months ended September 30, 2018 and 2017 was $1.8 million, a decrease of $31,000.

Loan and lease related expenses for the three months ended September 30, 2018 were $1.0 million compared to $891,000 for the three months ended September 30, 2017, an increase of $124,000 or 13.9%. Loan and lease related expenses for the nine months ended September 30, 2018 were $3.9 million compared to $2.6 million for the nine months ended September 30, 2017, an increase of $1.3 million. The increases were primarily driven by loan originations during the quarter and additional loans from the First Evanston acquisition.

Legal, audit and other professional fees for the three months ended September 30, 2018 were $2.4 million compared to $1.6 million for the three months ended September 30, 2017, an increase of $750,000 or 46.6%. Legal, audit and other professional fees for the nine months ended September 30, 2018 were $8.6 million compared to $4.4 million for the nine months ended September 30, 2017, an increase of $4.3 million, or 97.5%. The increases were primarily driven by increased legal and professional services incurred related to our recent acquisitions and the upcoming core system conversion.

Data processing expense for the three months ended September 30, 2018 was $2.7 million compared to $2.4 million for the three months ended September 30, 2017, an increase of $325,000, or 13.5%. The increase was primarily attributable to additional expenses associated with the First Evanston acquisition and upcoming core system conversion. Data processing expense was $15.4 million for the nine months ended September 30, 2018 compared to $7.3 million for the nine months ended September 30, 2017. The increase was primarily due to $8.1 million of contract termination expenses in connection with the upcoming core system conversion.

Net gain recognized on other real estate owned and other related expenses were $284,000 for the three months ended September 30, 2018 compared to a net loss of $565,000 for three months ended September 30, 2017, a decrease in expense of $849,000 or 150.2%. The decrease was primarily due to net gains recorded on sales of other real estate owned properties during the quarter. Net loss recognized on other real estate owned and other related expenses for the nine months ended September 30, 2018 were $187,000 compared to $136,000 for the nine months ended September 30, 2017. The increase in net loss recognized on other real estate owned and other related expenses was primarily attributed to decreased gains on sales due to decreased volume of sales of properties offset by decreased expenses due to decreased inventory of properties.

Regulatory assessments for the three months ended September 30, 2018 were $675,000 compared to $326,000 for the three months ended September 30, 2017, an increase of $349,000 or 106.6%. Regulatory assessments for the nine months ended September 30, 2018 were $1.3 million compared to $894,000 for the comparable period in 2017, an increase of $388,000 or 43.4%. The increases were primarily due to our increased asset size, offset by our improved risk profile as a result of improved financial ratios and performance.

Advertising and promotions for the three months ended September 30, 2018 were $537,000 compared to $196,000 for the three months ended September 30, 2017, an increase of $341,000 or 174.3%. Advertising and promotions were $1.1 million for the nine months ended September 30, 2018 compared to $803,000 for the comparable period in 2017, an increase of $330,000, primarily due to an increase in advertising and promotions attributable to our deposit promotional campaigns.

Telecommunications expense was $435,000 for the three months ended September 30, 2018 compared to $351,000 for the three months ended September 30, 2017, an increase of $84,000. Telecommunications expense was $1.3 million for the nine months ended September 30, 2018, an increase of $154,000 or 13.2% compared to the same period in 2017. The increases were primarily due to additional wireless services.

Other non-interest expense for the three months ended September 30, 2018 was $3.1 million compared to $3.7 million for the three months ended September 30, 2017, a decrease of $585,000 or 15.8%. The decrease includes impairment charges on assets held for sale of $139,000 for the three months ended September 30, 2018 compared to $951,000 for the comparable period in 2017.

Other non-interest expense was $7.6 million for the nine months ended September 30, 2018 compared to $7.2 million for the nine months ended September 30, 2017. Our provision for unfunded commitments was $496,000 for the nine months ended September 30, 2018 compared to $272,000 for the nine months ended September 30, 2017, an increase of $224,000, primarily due to growth in our unfunded loan and lease commitments. Operational insurance costs increased $199,000 and non-compete expenses increased $175,000 as a result of the acquisition. These increases were partially offset by a decrease in impairment charges on assets held for sale. During the nine months ended September 30, 2018, we incurred impairment charges on assets held for sale of $257,000 compared to $951,000 over the comparable period in 2017.

Our efficiency ratio was 56.57% for the three months ended September 30, 2018, compared to 69.92% for the three months ended September 30, 2017. The improvement in our efficiency ratio for the three months ended September 30, 2018 is primarily attributable to the increase in our net interest income resulting from our acquisition of First Evanston. Our efficiency ratio was 68.87% for the nine months ended September 30, 2018, compared to 67.76% for the comparable period in 2017. The change in our efficiency ratio for the nine months ended September 30, 2018 is primarily attributable to increased non-interest expense resulting from our acquisition and integration of First Evanston, including merger related expenses and core system conversion expenses. Our adjusted efficiency ratio was 55.78% for the three months ended September 30, 2018, compared to 67.73% for the three months ended September 30, 2017. Our adjusted efficiency ratio was 61.93% for the nine months ended September 30, 2018, compared to 67.02% for the comparable period in 2017. 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 tax expense was $5.4 million for the three months ended September 30, 2018 compared to a benefit of $1.4 million for the three months ended September 30, ~~2017 compared to expense of $9,000 for the three months ended September 30, 2016.~~2017. As part of a budget package passed by the Legislature of the State of Illinois, the corporate income tax rate increased from 5.25% to 7.00% effective July 1, 2017. As a result of the increase in the corporate income tax rate, during the third quarter of 2017 we recorded a state income tax benefit of $4.6 million due to increased value of our deferred tax asset related to our Illinois net loss deduction.

Our provision for income taxes for the nine months ended September 30, ~~2017~~2018 totaled ~~$7.2~~$7.8 million compared to ~~a benefit of $222,000~~$7.2 million for the nine months ended September 30, ~~2016.~~2017. The increase in income tax expense iswas primarily due to increased net income partially offset by the ~~reversal~~lower tax rate of ~~our deferred~~“H.R. 1”, commonly known as the “Tax Cuts and Jobs Act” (“Tax Act”), which was signed into law on December 22, 2017. Among other items, the law reduced the federal corporate income tax ~~asset valuation allowance at~~rate to 21% effective January 1, 2018. As a result of the ~~end of 2016~~new 21% corporate federal tax rate, the Company expects its effective tax rate for 2018 to be between approximately 27% and ~~the increase in taxable income for the three and nine months ended September 30, 2017 compared to the same periods in 2016.~~29%. Our effective tax rate was ~~24.4%~~20.0% for the nine months ended September 30, ~~2017.~~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. At September 30, 2018, the Company’s accounting for the impact of the Tax Act on its net deferred tax assets is based upon reasonable estimates of the tax effects of the Tax Act; however, these estimates may change as additional information and interpretive guidance regarding the provisions of the Tax Act become available. As a result of the rate change, the Company’s net deferred tax assets were required to be revalued, and we recorded a net income tax benefit of $724,000 during the first quarter of 2018.

Our total assets increased by ~~$9.6 million,~~$1.6 billion, or ~~0.3%~~46.1%, to ~~$3.3~~$4.9 billion at September 30, ~~2017,~~2018, compared to December 31, ~~2016.~~2017. The increase in total assets includes an increase of ~~$68.5 million,~~$1.2 billion, or ~~3.2%~~51.7%, in loans and leases, ~~from $2.1 billion at December 31, 2016 to $2.2 billion at September 30, 2017. The~~an increase ~~in loans and leases was offset by a decrease~~ in investment securities of ~~$41.3~~$197.7 million, and an increase in interest bearing deposits with other banks of $80.6 million. These increases are primarily attributed to ~~fund~~the First Evanston acquisition and organic loan and lease growth. ~~Due from counterparty increased $21.1 million related to loan sales not settled offset by a decrease in loans held for sale of $21.9 million.~~

The investment securities portfolio consists of securities classified as available-for-sale and held-to-maturity. There were no trading securities classified in our investment portfolio as of September 30, ~~2017~~2018 or December 31, ~~2016.~~2017. 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~~mortgage- backed securities and U.S. government agencies securities.

Securities available-for-sale ~~decreased $23.9~~increased $212.2 million, from ~~$608.6~~$583.2 million at December 31, ~~2016~~2017 to ~~$584.7~~$795.4 million at September 30, ~~2017.~~2018. The ~~decrease~~increase was primarily due to the ~~redeployment~~acquisition of ~~liquidity into higher yielding loans~~the First Evanston securities portfolio, as well as additional purchases of agency, mortgage-backed, and ~~leases.~~U.S. Treasury securities during the year.

~~The~~Our held-to-maturity securities portfolio consists of mortgage-backed securities and obligations of states, municipalities and political subdivisions. We carry these securities at amortized ~~cost. As of~~cost, and at September 30, ~~2017 this portfolio~~2018 totaled ~~$121.5~~$102.7 million compared to ~~$138.8~~$117.2 million at December 31, ~~2016.~~2017, a decrease of $14.5 million, or 12.4%, due to principal paydowns received during the year.

We had no securities that were classified as having ~~other than temporary impairment as of~~other-than-temporary-impairment at September 30, ~~2017~~2018 or December 31, ~~2016.~~2017.

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

~~We did not classify any securities as trading securities during 2017 or 2016.~~

Certain securities have fair values less than amortized cost and, therefore, contain unrealized losses. At September 30, ~~2017,~~2018, we evaluated the securities which had an unrealized loss for other than temporary impairment and determined all declines in value to be temporary. There were ~~113~~341 investment securities with unrealized losses at September 30, ~~2017, of which only one had a continuous unrealized loss position for 12 consecutive months or longer that is greater than 5% of amortized cost.~~2018. 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 table (dollars in thousands) sets 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.

Total non-taxable securities classified as obligations of states, municipalities and political subdivisions were ~~$27.5~~$45.9 million at September 30, ~~2017,~~2018, an increase of ~~$8.5~~$19.2 million from December 31, ~~2016.~~2017.

There were no holdings of securities of any one issuer, other than U.S. government-sponsored entities and agencies, with total outstanding balances greater than 10% of our stockholders’ equity as of September 30, ~~2017~~2018 or December 31, ~~2016.~~2017.

As a member of the Federal Home Loan Bank system, our 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, our 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, ~~2017~~2018 and December 31, ~~2016,~~2017, we held approximately ~~$10.6~~$19.2 million and ~~$15.0~~$16.3 million, respectively, in FHLB and Bankers’ Bank stocks. 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, ~~2017~~2018 and December 31, ~~2016.~~2017.

Lending-related income is the most important component of our net interest income and is the main driver of the results of our operations.

Our originated loan and lease portfolio increased ~~$192.1~~$492.8 million ~~offset by a decrease in the~~and our acquired loan and lease portfolio ~~of $123.6~~increased $685.5 million during the first nine months of ~~2017.~~2018. The growth in the originated loan and lease portfolio was primarily driven by increases in commercial ~~real estate loans, commercial~~ and industrial loans and ~~leases, partially offset~~leases. The growth in the acquired loan and lease portfolio was driven by ~~decreases in construction, land development and other land loans.~~the First Evanston acquisition.

At September 30, ~~2017, 49.8%~~2018, 47.2% of the loan and lease portfolio bears interest at fixed rates and ~~50.2%~~52.8% 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 ASC 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 ~~above~~presented include information limited to contractual maturities of the underlying loans.

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 element 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 acquisition or recapitalization.

Total ALLL was ~~$16.0~~$23.4 million at September 30, ~~2017~~2018 compared to ~~$10.9~~$16.7 million at December 31, ~~2016,~~2017, an increase of ~~$5.1~~$6.7 million, or ~~46.3%~~40.2%. The increase was primarily due to an increase in specific reserve on a commercial loan relationship, additional specific impairment in the ~~overall~~unguaranteed portion of the government guaranteed portfolio, ~~growth~~ and ~~increased weighting of our qualitative factors.~~an increase to the general reserve driven by new loan and lease originations.

Total ALLL to total loans and leases held for investment, net before ALLL was ~~0.72%~~0.68% and ~~0.51%~~0.73% of total loans and leases at September 30, ~~2017~~2018 and December 31, ~~2016,~~2017, respectively. The decrease was primarily driven by the acquisition of the First Evanston loan portfolio. This ratio is generally below the median of our peer banks, as we valued significant amounts of acquired loans at fair value at acquisition date as a result of our recapitalization, the ~~Recapitalization~~Ridgestone acquisition, and the ~~Ridgestone~~First Evanston acquisition, which, management believes, limits the amount of reserves needed to cover these loans as of September 30, ~~2017~~2018 and December 31, ~~2016,~~2017, in accordance with applicable accounting guidance. Acquisition accounting adjustments remaining ~~balances resulting~~on loans from ~~the Recapitalization and~~our recapitalization, the Ridgestone acquisition, and the First Evanston acquisition totaled ~~$34.2~~$42.4 million and ~~$43.2~~$31.7 million as of September 30, ~~2017~~2018 and December 31, ~~2016,~~2017, respectively.

The increase of non-performing assets from December 31, ~~2016~~2017 to September 30, ~~2017~~2018 was primarily ~~due to an increase in non-accrual loans of $8.3 million, primarily in the~~driven by one downgraded commercial loan relationship and downgraded government guaranteed ~~loan portfolio,~~loans, partially offset by a decrease in other real estate owned of ~~$2.7~~$5.7 million. Non-performing assets consisted of $7.3 million and $4.5 million of government guaranteed balances at September 30, 2018 and December 31, 2017, respectively.

Total OREO held by us was ~~$13.9~~$4.9 million as of September 30, ~~2017,~~2018, a decrease of ~~$2.7~~$5.7 million from December 31, ~~2016.~~2017. The decrease in OREO resulted from dispositions of ~~$8.0~~$6.8 million, ~~and valuation adjustments of $367,000,~~ offset by net additions to OREO through loan foreclosures totaling ~~$5.7~~$1.5 million.

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.

Total non-accrual loans increased by $8.3 million between December 31, 2016 and September 30, 2017 due to additional non-accrual loans primarily from the government guaranteed loan portfolio. The government guaranteed portion on non-accrual loans totaled $4.1 million at September 30, 2017.

Total accruing loans past due ~~decreased from $14.1~~increased to $15.8 million at September 30, 2018 compared to $15.2 million at December 31, ~~2016 to $7.5 million at September 30, 2017.~~ 2017, an increase of $600,000, or 4.0%. Increases in commercial real estate and lease financing receivables are partially offset by a decrease in commercial and industrial.

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.

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.

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 totaled ~~$30.8~~$24.4 million at September 30, ~~2017, an increase~~2018, a decrease of ~~$13.6~~$6.7 million compared to December 31, ~~2016.~~2017.

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, please see “Consolidated Statements of Cash Flows” in our Unaudited Interim Condensed Consolidated Financial Statements included elsewhere in this report.

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~~Common Equity Tier 1 (‘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, ~~2017,~~2018, Byline Bank exceeded all applicable regulatory capital requirements and was considered “well-capitalized”. There have been no conditions or events since September 30, ~~2017~~2018 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 capital conservation buffer requirement began to be

phased in on January 1, 2016 when a buffer greater than 0.625% of risk-weighted assets was required, which amount increases each year until the buffer requirement is fully implemented on January 1, 2019. As of January 1, ~~2017~~2018 the capital conservation buffer requirement was ~~1.25%~~1.875%. The conservation buffers for the Company and Byline Bank exceed the fully phased in minimum capital requirement as of September 30, ~~2017.~~2018.

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, 2018, the Company received $2.1 million 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 other Company activities. For the year ended December 31, 2017, the Company received ~~$2.2~~$2.8 million in cash dividends from Byline Bank to pay interest on the line of credit, interest ~~the~~payments on its trust preferred securities, ~~interest~~ and dividends on its preferred ~~dividends. There were no cash dividends received by the Company from Byline Bank for the year ended December 31, 2016.~~stock.

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 Interim Unaudited Condensed Consolidated Financial Statements, included elsewhere in this report for additional information.

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).

~~Standby letters~~Letters of credit are conditional commitments issued by Byline Bank 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.

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.

~~The following table summarizes commitments as of the dates presented (dollars in thousands).~~

During the nine months ended September 30, ~~2017~~2018 and for the year ended December 31, ~~2016,~~2017, we entered 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 entered 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 instrument. 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 September 30, ~~2017~~2018 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):

	September 30, 2017						September 30, 2018
			Fair Value						Fair Value
	Notional		Asset		Liability		Notional		Asset		Liability

~~This report contains certain~~Some of the financial ~~information determined by methods other than~~measures included in our “Selected Financial Data” are not measures of financial performance in accordance with ~~accounting principles generally accepted~~GAAP. Our management uses the non‑GAAP financial measures set forth below in its analysis of our performance:

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 ~~intangible assets.~~companies use. Management believes this measure 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.also uses these measures for peer comparison.

Because forward-looking statements are necessarily only estimates of future strategies, actions or results, based on management’s current expectations, assumptions and estimates on the date hereof, and there can be no assurance that actual strategies, actions or results will not differ materially from expectations, readers are cautioned not to place undue reliance on such statements. Factors that may cause such a difference include, but are not limited to, the reaction to the transaction of the companies’ customers, employees and counterparties; customer disintermediation; inflation; expected synergies, cost savings and other financial benefits of the proposed transaction might not be realized within the expected timeframes or might be less than projected; the requisite stockholder and regulatory approvals for the proposed transaction might not be obtained; credit and interest rate risks associated with Byline’s and Oak Park River Forest Bankshares, Inc.’s respective businesses, customers, borrowings, repayment, investment, and deposit practices; general economic conditions, either nationally or in the market areas in which Byline and Oak Park River Forest Bankshares, Inc. operate or anticipate doing business, are less favorable than expected; new regulatory or legal requirements or obligations; and other risks. Certain risks and important factors that could affect Byline’s future results are identified in its Annual Report on Form 10-K for the year ended December 31, 2017 and other reports filed with the Securities and Exchange Commission, including among other things, under the heading “Risk Factors” in such Annual Report on Form 10-K. Any forward-looking statement speaks only as of the date on which it is made, and Byline undertakes no obligation to update any forward-looking statement, whether to reflect events or circumstances after the date on which the statement is made, to reflect new information or the ~~negative version~~occurrence of ~~those words~~unanticipated events, or other comparable words or phrases of a future or forward-looking nature. Forward-looking statements represent management’s current beliefs and expectations regarding future events, such as our anticipated future financial results, credit quality, liquidity, revenues, expenses, or other financial items, and the impact of business plans and strategies or legislative or regulatory actions.otherwise.

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:

These factors should be considered in evaluating forward-looking statements, and you should not place undue reliance on any forward-looking statements, which 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 ~~prospectus in connection with our initial public offering that we filed with the SEC on July 3, 2017,~~Form 10-K, 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 our subsequent periodic and current reports filed 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.

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 ~~(“NOW”)~~ accounts, savings accounts and money market deposits accounts ~~(“MMDAs”)~~ 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 ~~SBA~~government guaranteed loans we make and the related servicing rights. Our ~~SBA~~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~~Byline Bank’s asset liability committee, and is chaired by ~~Byline Bank’s~~its 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 to 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 associated 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 ~~client~~customers’ and Byline ~~Bank~~Bank’s needs. Typically, customer interest rate swaps are for terms of more than 5 years. As of September 30, ~~2017,~~2018, we had a notional amount of ~~$331.7~~$486.9 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, SBA requirements, 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.

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.

~~Potential changes~~The potential change to our net interest income in hypothetical rising and declining rate scenarios calculated as of September 30, ~~2017~~2018 is presented in the following 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 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 200, 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~~below 0%. For the dynamic balance sheet and rate shift scenarios, we assume interest rates follow a forward yield curve and then ~~ramp~~increase it up by 1/12th of the total change in rates each month for twelve months.

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.

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, ~~2017,~~2018, 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.

There was no change in our internal control over financial reporting during the quarter ended September 30, ~~2017,~~2018, 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.

We operate in a highly regulated environment. From time to time we are a party to various litigation matters incidental to the conduct of our business. We are not presently party to any legal proceedings the resolution of which we believe would have a material adverse effect on our business, prospects, financial condition, liquidity, results of operation, cash flows or capital levels.

There have been no material changes ~~from~~to the risk factors previously disclosed in the “Risk Factors” section included in our ~~prospectus dated June 29,~~Form 10-K for our fiscal year ended December 31, 2017 that was filed with the SEC on ~~July 3, 2017 pursuant~~March 30, 2018, except as noted below.

We may be adversely affected by risks associated with our planned core banking system conversion, including failure to ~~Rule 424(b)(4) under~~realize anticipated benefits and to overcome integration risks, which could adversely affect our growth, profitability, and customer experience.

In order to support our continued growth and to continue to provide first-rate banking products and services to our customers, we have decided to convert our core bank processing platform to FIS’s Integrated Banking Services. We anticipate that the ~~Securities Act.~~

final conversion will occur during 2019. There can be no assurance that we will be able to realize the full anticipated benefits of the conversion and overcome associated integration risks.

On June 29, 2017, the Company sold 4,630,194 shares of its common stock in its initial public offering, including 855,000 shares of common stock pursuant to the underwriters’ exercise of their option to purchase additional shares to cover over-allotments. The aggregate offering price for the shares sold by the Company was $88.0 million, and after deducting $6.2 million of underwriting discounts and $5.0 million of offering expenses paid to third parties, the Company received total net proceeds of $76.8 million. In addition, certain selling stockholders participated in the offering and sold an aggregate of 1,924,806 shares of our common stock at an aggregate offering price of $36.6 million. All of the shares were sold pursuant to our Registration Statement on Form S-1, as amended (File No. 333- 218362) (the “Registration Statement”), which was declared effective by the SEC on June 29, 2017 and registered shares of our common stock with a maximum aggregate offering price of $137.7 million. Merrill Lynch, Pierce, Fenner & Smith Incorporated and Keefe, Bruyette & Woods, Inc. acted as joint book-running managers for the offering, and Piper Jaffray & Co., Sandler O’Neill + Partners, L.P. and Stephens Inc. acted as co-managers. Our common stock is currently traded on the New York Stock Exchange under the symbol “BY”.None.

There has been no material change in the planned use of proceeds from our initial public offering as described in our prospectus dated June 29, 2017 that was filed with the SEC on July 3, 2017 pursuant to Rule 424(b)(4) under the Securities Act. From the effective date of the Registration Statement through the date of the filing of this report, the Company used $25.5 million to repurchase all of its outstanding Noncumulative Perpetual Preferred Stock, Series A, on July 14, 2017 and $16.2 million to pay down its line of credit on July 6, 2017.

(a) This exhibit shall not be deemed “filed” for purposes of Section 18 of the Exchange Act, or otherwise subject to the liability of that section, and shall not be deemed to be incorporated by reference into any filing under the Securities Act or the Exchange Act.

Pursuant to the requirements of the Securities Exchange Act of 1934, the Registrant has duly caused this report to be signed on its behalf by the undersigned thereunto duly authorized.
