What does it mean if I receive more than one proxy form?

It means that you have multiple holdings reflected in our stock transfer records and/or in accounts with stockbrokers.  Please sign and returnALL proxy forms to ensure that all your shares are voted.

If I hold shares in the name of a broker, who votes my shares?

If you received this proxy statement from your broker, your broker should have given you instructions for directing how your broker should vote your shares.  It will then be your broker'sbroker’s responsibility to vote your shares for you in the manner you direct.

Under the rules of various national and regional securities exchanges,applicable stock exchange rule, brokers may generally vote on routine matters, such as ratifying the appointment of an independent registered public accounting firm, but cannot vote on non-routinenon‑routine matters, such as the adoption or amendmentelection of a stock incentive plan, directors, the say-on-pay proposal, the say-on-frequency proposal, and the 2019 Equity Incentive Plan proposal, unless they have received voting instructions from the person for whom they are holding shares.  If there is a matter presented to stockholders at athe meeting and your broker does not receive instructions from you on how to vote on that matter, your broker will return the proxy card to us, indicating that he or she does not have the authority to vote on that matter.  This is generally referred to as a "broker non-vote" and may affect the outcome“broker non‑vote.”

Each of the voting on those matters.

The electionproposals you will be asked to consider and vote upon at the annual meeting, other than the ratification of the appointment of our independent registered accountants, the proposed amendment to our certificate of incorporation eliminating the mandatory retirement age for directors, and the say-on-pay proposals areadjournment proposal, is considered non-routine matters.a  non‑routine matter.  Therefore, we encourage you to provide directions to your broker as to how you want your shares voted on all matters to be brought before the 20162019 annual meeting upon receipt of our proxy materials.  You should do this by carefully following the instructions your broker gives you concerning its procedures.  This ensures that your shares will be voted at the meeting.

What if I change my mind after I return my proxy card?

If you hold your shares in your own name, you may revoke your proxy and change your vote at any time before the polls close at the meeting.  You may do this by:

•

signing another proxy card with a later date and returning that proxy card to us;

•

sending notice to us that you are revoking your proxy, or

•

voting in person at the meeting.

If you hold your shares in the name of your broker or other fiduciary and desire to revoke your proxy, you will need to contact that party to revoke your proxy.

How many votes do we needshares must be represented for us to hold the annual meeting?

A majority of the shares that were outstanding and entitled to vote as of the record date must be present in person or by proxy at the meeting in order to hold the meeting and conduct business.  On March 25, 2016,29, 2019, the record date, there were 29,483,429[—] shares of common stock outstanding.  A majority of these shares must be present in person or by proxy at the meeting.

Shares are counted as present at the meeting if the stockholder either:

•

is present in person at the meeting; or

•

has properly submitted a signed proxy form or other proxy.

What happens if any nominee is unable to stand for re-election?

The board may, by resolution, provide for a lesser number of directors or designate a substitute nominee.  In the latter case, shares represented by proxies may be voted for a substitute nominee.  Proxies cannot be voted for more than threefour nominees.  The board has no reason to believe any nominee will be unable to stand for re-election.

What options do I have in voting on each of the proposals?

Except with respect to the election of directors, youYou may vote "for," "against"“FOR,” “AGAINST” or "abstain"“ABSTAIN” on each proposal properly brought before the meeting. Inmeeting, other than the say-on-pay frequency proposal, including the election of directors youdirectors.  You may vote "for"for “EVERY YEAR,” “EVERY TWO YEARS,” “EVERY THREE YEARS,” or "withhold authority to vote for" each nominee.“ABSTAIN” on the say-on-frequency proposal.

How many votes may I cast?

Generally, youYou are entitled to cast one vote for each share of stock you owned on the record date with respect to each of the proposals.  Stockholders do not have cumulative voting rights.  The proxy card included with this proxy statement indicates the number of shares owned by an account attributable to you.

What is the quorum for the annual meeting?

A majority of our outstanding shares of common stock as of the record date must be present at the meeting, either in person or by proxy, to hold the meeting and conduct business.  This is called a quorum. In determining whether we have a quorum at the annual meeting for purposes of all matters to be voted on, all votes “FOR” or “AGAINST” and all votes to “ABSTAIN” will be counted.  Shares will be counted for quorum purposes if they are represented at the meeting for any purpose other than solely to object to holding the meeting or transacting business at the meeting.  If you hold your shares in street name, your brokerage firm may vote your shares under certain circumstances.  Brokerage firms have authority under stock exchange rules to vote their customers’ unvoted shares on certain “routine” matters.  We

expect that brokers will be allowed to exercise discretionary authority for beneficial owners who have not provided voting instructions ONLY with respect to Proposal 5 – the amendment of our certificate of incorporation, Proposal 6 - the ratification of Plante & Moran, PLLC as our independent registered public accounting firm for the year ending December 31, 2019, and Proposal 7 -  the adjournment proposal, but not with respect to any of the other proposals to be voted on at the annual meeting.  If you hold your shares in street name, please provide voting instructions to your bank, broker or other nominee so that your shares may be voted on all other proposals.

When a brokerage firm votes its customers’ unvoted shares on routine matters, these shares are counted for purposes of establishing a quorum to conduct business at the meeting.  If a brokerage firm indicates on a proxy that it does not have discretionary authority to vote certain shares on a particular matter, then those shares will be treated as “broker non‑votes”.  Shares represented by broker non‑votes will be counted in determining whether there is a quorum.

No notice of an adjourned meeting need be given if the time and place of the adjourned meeting are announced at the annual meeting, unless the adjournment is for more than 30 days or if, after the adjournment, a new record date is fixed for the adjourned meeting, in which case a notice of the adjourned meeting shall be given to each shareholder of record entitled to vote at the meeting.  At an adjourned meeting, all proxies will be voted in the same manner as they would have been voted at the original convening of the annual meeting, except for any proxies that have been effectively revoked or withdrawn prior to the adjourned meeting.

How many votes are needed for each proposal?

A majority of votesAssuming a quorum is present, and entitled to vote at the meeting will approve each matter that arises at the annual meeting.

The directors are elected by a majority of the shares having voting power present in person or represented by proxy must approve each proposal brought before the annual meeting other than the say-on-frequency proposal and the proposal to amend our certificate of incorporation (meaning that the number of votes present and entitledcast “FOR” each proposal must exceed the number of votes cast “AGAINST” or “ABSTAIN” with respect to vote atthat proposal).  This includes the meeting. Forproposal regarding the election of directors in accordance with the policy of majority voting in uncontested director elections set forth in our bylaws.  The proposal to amend our certificate of incorporation must be approved by 75% of the voting power of all outstanding shares of our common stock.  With respect to the say-on-frequency proposal, the alternative receiving the highest number of votes will be considered the preference of our stockholders.

Broker non‑votes will not affect the outcome of voting on a "withhold authority" voteparticular proposal other than the proposal to amend our certificate of incorporation or the election of directors, but abstentions will have the same effect asof a vote against the electionapplicable proposal or director.  Broker non-votes will have the effect of a particular director.vote against the proposal to amend our certificate of incorporation.

Please note that, because the say-on-pay vote issay‑on‑pay and say-on-frequency votes are advisory, itthey will not be binding upon the board of directors or the Compensation Committee.

Abstentions and broker non-votes, if any, will not be counted as entitled to vote, but will count for purposes of determining whether or not a quorum is present. So long as a quorum is present, abstentions and broker non-votes will have no effect on the election of directors. Abstentions will have the effect of a vote against the say-on-pay proposal and the ratification of the appointment of our independent registered public accounting firm, while broker non-votes will not affect these votes.

How are votes counted?

Voting results will be tabulated and certified by the election judges.

CORPORATE GOVERNANCE AND THE BOARD OF DIRECTORS

General

Currently, the board of directors is made up of teneleven directors, who are elected by the holders of our common stock every three years to serve staggered terms.  In accordance with our corporate governance procedures, the board does not involve itself in the day-to-dayday‑to‑day operations of Old Second, which is monitored by our executive officers and management.  Our directors fulfill their duties and responsibilities by attending regular meetings of the board and through committee membership, which is discussed below. The board has determined that all of the directors and nominees are "independent" as defined by the Nasdaq Stock Market, with the exception of Messrs. Skoglund, Cheatham and Eccher, each of whom is an executive officer or was an executive officer during the past three calendar years.

Director Attendance

The board of directors held 11ten regular and one special meetings during 2015.2018.   All of the directors attended at least 75% of these meetings and the meetings of the committees on which they served.  We typically schedule a board meeting in conjunction with our annual meeting and expect that our directors will attend our annual meeting. Last year, all of our then‑serving directors attended our annual meeting.

Code of Business Conduct and Ethics

The board of directors believes that it is important to encourage the highest level of corporate ethics and responsibility.  Among other things, the board adopted a Code of Business Conduct and Ethics, which applies to all of our directors, officers and employees, as well as a procedure for allowing employees to anonymously report any problems they may detect with respect to our financial reporting.  The Code of Business Conduct and Ethics, as well as other information pertaining to our committees, corporate governance and reporting with the Securities and Exchange Commission, can be found on our website at www.oldsecond.com.  The Company will post on its website any amendments to, or waiver from, the Code of Business Conduct and Ethics as it applies to any director or officer to the extent required to be disclosed by applicable NASDAQ or SEC requirements.

Director Independence

The board of directors has standing Audit, Nominating and Corporate Governance, and Compensation Committees, each of which is made up solely of directors who are deemed to be "independent"“independent” under the rules of Nasdaq. Nasdaq'sNASDAQ. NASDAQ’s independence rules include certain instances that will preclude a director from being deemed independent and the board reviews those requirements each year to determine a director'sdirector’s status as an independent director.  The board has determined that all of the directors and nominees are “independent” as defined by the NASDAQ Stock Market, with the exception of Messrs. Eccher and Collins, each of whom has been an executive officer of the Company during the past three calendar years ended December 31, 2018.

During its review of director independence, the board considered Mr. Finn'sFinn’s roles as President and Chief Executive Officer at Rush-CopleyRush‑Copley Medical Center and Mr. Skoglund'sSkoglund’s position as the Vice Chairman of Rush-Copley'sRush‑Copley’s board of directors.  Our board determined that this does not preclude a finding that Mr. Finn is independent under Nasdaq'sNASDAQ’s  rules because Mr. Skoglund does not serve on Rush-Copley'sRush‑Copley’s compensation committee and has recused himself from any discussions or votes that involve Mr. Finn'sFinn’s salary. The board also reviewed certain transactions between Alarm Detection Systems, Inc., and the Company. Mr. Bonifas is aan Executive Vice President of Alarm Detections Systems, Inc.  The board determined that Mr. Bonifas qualified as an independent director because the amounts paid by the Company to Alarm Detection Systems in 2018, which totaled approximately $257,540, by the Company$214,921, were less than 5% of Alarm Detection System'sSystem’s gross revenues for 20152018 and because Mr. Bonifas had no interest in the transaction with the Company, except an indirect andde minimis interest as a shareholderstockholder of Alarm Detection Systems.

Actions taken by each committee of the board are reported to the full board, usually at its next meeting.  The principal responsibilities of each of the committees are described below.

Committees of the Board of Directors

Our board committees are currently composed as follows (M — member; C — chair):

Director Nominations and Qualifications

In making its nominations for persons to be elected to the board of directors and included in our proxy statement, the Nominating and Corporate Governance Committee evaluates incumbent directors, board nominees and persons nominated by stockholders, if any.  The committee reviews each candidate in light of the criteria that we believe each director should possess.  Included in the criteria are whether each nominee: (i) meets the minimum requirements for service on the board of directors contained in our bylaws; (ii) is under the age of 70 at the time of his or her election, as required byin accordance with our certificate of incorporation;incorporation (but see Proposal 5 for a proposed amendment to the certificate of incorporation regarding this criterion);  (iii) possesses the highest personal and professional ethics, integrity and values; (iv) has, in the committee'scommittee’s opinion, a sufficient educational and professional background and relevant past and current employment affiliations, board

affiliations and experience for service on the board; (v) has demonstrated effective leadership and sound judgment in his or her professional life; (vi) has a strong sense of service to the communities thatin which we serve; (vii) has exemplary management and communication skills; (viii) is free of conflicts of interest that would prevent him or her from serving on the board; (ix) will ensure that other existing and future commitments do not materially interfere with his or her service as a director; (x) will review and agree to meet the standards and duties set forth in the Company'sCompany’s Code of Business Conduct and Ethics; (xi) is willing to devote sufficient time to carrying out his or hertheir duties and responsibilities effectively; and (xii) is committed to serving on the board for an extended period of time.  While we do not have a separate diversity policy, the committee does consider the diversity of its directors and nominees in terms of knowledge, experience, skills, expertise and other demographics which may contribute to the board.  The committee also evaluates potential nominees to determine if they have any conflicts of interest that may interfere with their ability to serve as effective board members and to determine whether they are "independent"“independent” in accordance with NasdaqNASDAQ requirements (to ensure that at least a majority of the directors will, at all times, be independent).

The committee, when considering potential board members, will look at all of the foregoing criteria and arrive at the candidate that best meets the items set forth.criteria.  The various qualifications and criteria are normally considered by the committee in connection with its evaluation of who the committee will recommend as the Company'sCompany’s nominees.  Generally, each incumbent director standing for re-electionre‑election should have and will have, at a minimum, attended at least 75% of board meetings during the past year and attended a majority75% of committee meetings of which he or she is a member.  The committee retains the ability to make exceptions to this attendance requirement as individual circumstances warrant.

All of the nominees for election as directors forat the 20162019 annual meeting were nominatedrecommended for nomination by the committee.  The committee did not receive any formal nominations for directors from our common stockholders.

Common Stock Ownership and Retention Guidelines for Directors

In order to align the interests of board members and stockholders, we require each director is required to develop a significant equity stake in the organization they oversee.company.  The Compensation Committee is responsible for monitoring compliance with these stock ownership and retention guidelines.

            Non-employeeNon‑employee directors are expected to acquire and hold during their service as board members, shares of our common stock equal in value to at least three times the annual cash retainer for non-employeenon‑employee directors.  Non-employeeNon‑employee directors have three years from their initial election to the board to meet the target stock ownership guidelines. Once they obtain the requisite number of shares, they are expected to continuously own sufficient shares to meet the guidelines.  The stock ownership goal will be determined by using the value of their retainers as of January 1 of each year and the average closing stock price for our common stock over the prior twelve months.

Shares that count toward meeting the stock ownership guidelines include: (i) shares owned, which include shares obtained upon exercise of options or shares purchased in the open market; (ii) shared ownership, which includes shares owned or held in trust by immediate family; and (iii) restricted stock units.  Unexercised stock options do not count toward meeting the stock ownership guidelines.  Until such time as the director reaches his or her target stock ownership, the director will be required to hold 50% of the shares of common stock received upon lapse of the restrictions, and upon exercise of stock options.  In the rare instance in which these guidelines would place a severe hardship on a director, the Compensation Committee may decide to allow an alternative stock ownership guideline that reflects the intentions of these overall guidelines and the directors'director’s own personal circumstances.

Board Leadership Structure

The roles of Chairman of the Board and Chief Executive Officer are separate positions within our Company. Mr. Skoglund, our former Chief Executive Officer, serves as our Chairman, and Mr. Eccher serves as our Chief Executive Officer and President.  We currently separate the roles of Chairman and Chief Executive Officer in recognition of the differences between the two roles.

Our board of directors has also created the position of a "lead"“lead” independent director, who assists the board of directors in assuring effective corporate governance, and serves as chairman when the board of directors meets in independent director sessions. In 2015, Gerald Palmer served as our lead independent director until his resignation on October 13, 2015 in connection with his reaching the mandatory retirement age. Subsequently,2018, our board of directors designated Mr. Finn to serve as the Company'sCompany’s lead independent director.  The Nominating and Corporate Governance Committee reviews this appointment annually and the full board has the opportunity to ratify the committee'scommittee’s selection.

Our board of directors believes this structure is appropriate for our Company because it allows the Chief Executive Officer to focus on our strategic direction and our day-to-dayday‑to‑day leadership and performance, and we are also able to leverage the experience and perspective of the Chairman through his guidance to the Chief Executive Officer and his management team as well as to the board of directors.  In addition, the lead independent director, who is an independent member of our Board, provides independent leadership within our Board that strengthens its effectiveness and oversight of our business.

Board'sBoard’s Role in Risk Oversight

Risk is inherent with every business, and how well a business manages risk can ultimately determine its success.  We face a number of risks, including general economic risks, credit risks, regulatory risks, audit risks, reputational risks and others, such as the impact of competition.  Management is responsible for the day-to-dayday‑to‑day management of risks the Company faces, while the board, as a whole and through its committees, has responsibility for the oversight of risk management.  In its risk oversight role, the board of directors has the responsibility to satisfy itself that the risk management processes designed and implemented by management are adequate and functioning as designed.

While the full board of directors is charged with ultimate oversight responsibility for risk management, various committees of the board and members of management also have responsibilities with respect to our risk oversight.  In particular, the AuditRisk Committee plays a large role in monitoring and assessing our financial, legal and organizational risks, and receives regular reports from the management

team's team’s senior risk officer regarding comprehensive organizational risk as well as particular areas of concern.  The board'sboard’s Compensation Committee monitors and assesses the various risks associated with compensation policies, and oversees incentives that encourage a level of risk-takingrisk‑taking consistent with our overall strategy. Mr. Bonifas, the Chairman of the ITInformation Technology Steering Committee, will serveserves as our cybersecurity expert.  Additionally, our senior credit officer and loan review staff are directly responsible for overseeing our credit risk.

We believe that establishing the right "tone“tone at the top"top” and providing for full and open communication between management and the board of directors are essential for effective risk management and oversight.  Our executive management meets regularly with our other senior officers to discuss strategy and risks facing the Company. Senior officers attend many of the board meetings, or, if not in attendance, are available to address any questions or concerns raised by the board on risk management-relatedmanagement‑related and any other matters.  Additionally, each of our board-levelboard‑level committees provides regular reports to the full board and apprises the board of our comprehensive risk profile and any areas of concern.

For purposes of this review, related person transactions are those transactions required to be disclosed under applicable SEC regulations.

Banking Relationships

Overview and Executive Summary

Business Overview.The Company, through its banking subsidiary, provides lending, deposit, and trust services for businesses and individuals.  We offer competitive commercial and personal banking products and are committed to providing superior customer service.  We place a high priority on community service and are actively involved with

many civic and community projects in the communities where we conduct business.  We operate in an intensely competitive and uncertain business environment.  From a business perspective, not only do we compete with numerous companies in our markets for customers, but we also compete with many different types and sizes of organizations for senior leadership capable of executing our business strategies.  Among other challenges, our business model requires experienced leaders with banking and operational expertise who are capable of taking on high levels of personal responsibility in an ever-evolvingever‑evolving banking industry and economy.

Financial and Operational Performance.During our fiscal year ending December 31, 2015,2018, we continued our emphasis on sustaining profitability and growth as primary objectives.  Specific accomplishments in 20152018 that directly impacted those objectives include:

•

Reduction in classified assets by 39.2%;



•

·

Net income of $34.0 million for 2018, compared to $15.1 million for 2017; and

Commercial loan growth of 17.4% in 2018, including 4.1% of organic commercial loan growth compared to 2017.

Overview of Our Executive Compensation Programs.    It is important to note that theThe Company and the Bank share an executive management team, the members of which are compensated by the Bank rather than the Company.  The compensation packages of theour named executive officers are determined and approved by our Compensation Committee based uponon their performance and roles for both the Company and the Bank.

            The Company and the BankWe are committed to paying for performance.  This commitment is reflected by the significant portion of our named executive officers'officers’ compensation that is provided through performance-basedperformance‑based programs.  Our executive compensation programs evolve and are adjusted over time to support the business goals of the Company and the Bank and to promote both near-near‑ and long-termlong‑term profitable growth.  Total compensation for each named executive officer varies with performance in achieving financial and nonfinancial objectives.

Accordingly, our executive compensation, particularly metrics for the organization's short-termorganization’s short‑term incentive plans, focused on the following goals and accountabilities: our and the Bank'sBank’s net income growth; specific profit center performance; asset-creditthe Bank’s loan growth; asset‑credit quality risk;risk reduction and a reduction in classified assets; and cost savings initiatives.initiatives; and specific profit center performance.  These metrics were prudently designed to contain and minimize risk while at the same time emphasizing growth and profitability.

            Say-on-Pay.Say‑on‑Pay.      We received approximately 94% ofOf the votes cast on our say-on-pay proposal at our 2018 annual meeting, 97%  voted in support of the compensation of our named executive compensation program during the 2015 annual stockholders meeting. We, ourofficers.   Our board and the Compensation Committee pay careful attention to communications received from stockholders regarding executive compensation, including the non-bindingnon‑binding advisory vote. The Compensation Committee believes that these voting results reflect strong confidence in our board to exercise good judgement in structuring thoughtful executive compensation programs that benefit our stockholders.  We considered the positive result of the 20152018 advisory vote on executive compensation but not for specific 20152018 compensation decisions.  Based on this consideration and the other factors described in this CD&A, the Compensation Committee did not alter the policies or structure for named executives'executives’ compensation for 2015.2018.

Objectives of Our Compensation Program

The goal of our compensation program is to align the interests of management with those of our stockholders while minimizing undue risk-taking.risk‑taking.  The Compensation Committee has designed our executive compensation program

in a manner that does not provide our executives with incentives to engage in business activities or other behavior that would threaten our value or the investments of our stockholders.

The executive compensation program is intended to accomplish the following objectives:

•

Pay for performance;



•

tie equity compensation to long-term value creation for our stockholders;



•

align the financial interests of our named executive officers with those of our stockholders;



•

maintain a corporate environment that encourages stability and a long-term focus for both us and our management;

•

maintain a program that:



o

clearly motivates personnel to perform and succeed according to our current goals;



o

attracts and retains key personnel critical to our long-term success; and



o

does not encourage undue risk-taking; and



•

ensure that management:



o

fulfills its oversight responsibility to its constituents which include stockholders, customers, employees, the community and government regulatory agencies;



o

conforms its business conduct to the highest ethical standards;



o

remains free from any influences that could impair or appear to impair the objectivity and impartiality of its judgments or treatment of our constituents; and



o

continues to avoid any conflict between its responsibilities to us and each individual's personal interests.

Elements of Compensation

Our named executive officers'officers’ compensation program consists of four main components: (i) base salary, (ii) annual cash bonus,incentives,  (iii) equity awards, and (iv) additional benefits.

The Compensation Committee'sCommittee’s decisions regarding each of the components for the named executive officers are based in part on the Compensation Committee'sCommittee’s subjective judgment and take into account qualitative and quantitative factors, as are discussed below.  In reviewing an executive officer'sofficer’s compensation, the Compensation Committee considers and evaluates all components of the officer'sofficer’s total compensation package.  This involves reviewing base salary, bonus,bonus/cash incentives, equity incentive equity awards, perquisites, participation in our non-qualifiednon‑qualified executive plans, participation in our 401(k) plan and any other payments, awards or benefits that an officer earns.  Additionally, the Compensation Committee takes into consideration any amounts an executive officer is entitled to upon retirement, termination or a change-in-controlchange‑in‑control event.

The following overview explains the structure and rationale of the elements of compensation used for 2015.2018.

Base Salary.The Compensation Committee believes that base compensation should offer security to each executive sufficient to maintain a stable management team and environment.  In order to provide such stability, the Compensation Committee uses salaries to make up the largest portion of the named executives' compensation. In establishing an executive officer's officer’s  

initial base salary the Compensation Committee considers, among other things, the executive'sexecutive’s level of responsibility, prior experience, breadth of knowledge, the competitive salary practices at peer companies, internal performance objectives, education, internal pay equity, potential bonus and equity awards, level of benefits and perquisites and the tax deductibility of base salary.

The Compensation Committee reviews salaries of the named executive officers on an annual basis.  As with all of its decisions regarding compensation levels, when reviewing salaries the Compensation Committee considers the levels of all aspects and components of the officer'sofficer’s compensation, including the individual'sindividual’s potential bonus and equity awards as well as the level of benefits and perquisites offered.  All of these factors are considered on a subjective basis in the aggregate, and none of the factors is accorded a specific weight.

Annual Cash Bonus.Incentives.      In 2015, theThe Compensation Committee adopted a non-equitybelieves that annual cash incentive compensation plan (the "Bonus Plan") foris an integral component of our namedtotal compensation program that links executive officers. The Bonus Plan established a structure under which Messrs. Eccher, Cheatham, Gottschalkdecision‑making and Pilmer are eligible for cash bonus

Maximum bonus opportunities are capped to avoid encouraging excessive risk-taking and to avoid any focus on maximizing short-term results at the expense of long-term soundness.

            The Bonus Plan is designed to provide an incentive to achieve corporate financial goals while considering the mitigation of any risks which may affect our overall financial performance.

On February 20, 2018, the Compensation Committee approved the Old Second Bancorp, Inc. Executive Annual Incentive Plan, which we refer to as our “Incentive Plan.” Under the Incentive Plan, as soon as practicable at the beginning of each fiscal year, the Compensation Committee, in consultation with our Chief Executive Officer, selects key performance objectives, which will be used to determine the actual incentive cash payment to be awarded to our executive officers upon the achievement of the selected performance objectives.  Generally speaking, performance targets are set so that improvement in a performance metricobjective is necessary in order to receive any or all of the bonus payoutincentive award with respect to that metric.

Maximum incentive opportunities are capped under the Incentive Plan to avoid encouraging excessive risk‑taking and to avoid any focus on maximizing short‑term results at the Compensation Committee. expense of our long‑term soundness.

Equity Awards.  The Compensation Committee then, outside the presence of Mr. Eccher, considers factors applicable to Mr. Eccher's annual bonus.

            Equity Awards.    Our board and the Compensation Committee believe inbelieves that senior management equity ownership of our common stock as an effective means to aligneffectively aligns the interests of senior management with those of theour stockholders.  Our current long-termAccordingly, we have implemented equity‑based incentives to both encourage our management’s long‑term service and give management a more direct interest in our future success.  The equity incentive plan (the "Incentive Plan"),in effect in 2018, which was approved by our stockholders at thein 2014, annual meeting, is intended to promote equity ownershipand amended in the Company by the directors and selected officers and employees, focus the management team on increasing value to stockholders, increase their proprietary interest in the success of the Company and encourage them to remain in the employ of the Company or its subsidiaries for a long period of time. The2016 (the “Equity Incentive PlanPlan”), authorizes the issuance of up to 375,000 shares of our common stock, including the granting of qualified stock options, non-qualifiednon‑qualified stock options, restricted stock, restricted stock units and stock appreciation rights. In February 2016, the Board approved an amendment to increase the number of shares authorized for issuance under the Incentive Plan by 600,000 shares, pending shareholder approval. As a result, following shareholder approval, 975,000 shares will be authorized for issuance under our Incentive Plan.

            We also maintain our prior 2008 Equity Incentive Plan (the "2008 Plan"), which was approved by stockholders at the 2008 annual meeting. After the adoption of the Incentive Plan, no additional awards may be granted under the 2008 Plan. Any shares that become available for reuse under the 2008 Plan, whether due to forfeiture or otherwise, may be delivered under the Incentive Plan. The 2008 Plan authorized the issuance of up to 575,000 shares of our common stock, including the granting of qualified stock options, non-qualified stock options, restricted stock, restricted stock units and stock appreciation rights.

All awards are at the discretion of the Compensation Committee and are generally subjective in nature.  In determining the number of equity awards to be granted to executive officers, the Compensation Committee considers individual and corporate performance goals and whetherachievement as measured by those goals, the respective goals were obtained, the person'sexecutive’s position and his or her ability to affect profits and stockholder value, as well as the level of awards granted to individuals with similar positions at our peer organizations.  Because of the nature of equity awards, the Compensation Committee also evaluates the prior awards of stock options and restricted stock and takes into account the overall wealth accumulation of a given executive officer through such awards.

            PursuantAs discussed below in “Analysis of 2018 Compensation—Long-Term Equity Compensation,” in 2018, the Compensation Committee granted our named executive officers service-based restricted stock units that are subject to a formal equity compensation policy, all equity grants are finalized inthree-year cliff vesting.  In addition, with respect to Mr. Eccher, Mr. Adams and Mr. Collins, the beginning of each calendar year. This allows for a more complete review of the full prior year when making equity awards as well as coordinating the granting of equity awardsCompensation Committee awarded performance-based restricted stock units subject to a time when there is less likelihood of there being existing material, non-public information, as the grants will normally be made after the public release of our financial information for the prior year.specified performance conditions.

Additional Benefits

Retirement Benefits.We sponsor a tax-qualifiedtax‑qualified 401(k) savings plan and trust intended to be qualified under Section 401(k)��of the Internal Revenue Code.  Virtually all employees are eligible to participate after meeting certain age and service requirements.  Eligible employees are permitted to

contribute up to a dollar limit set by law. Participants can choose between several different investment options under the 401(k) plan, including shares of our common stock.

During 2015,2018, we provided a matching contribution on elective deferrals to eligible participants in an amount equal to 100% of the first 3% of each participant’s  contributions, and 50% of the next 2% of each participant's salary.the participant’s contributions.  There is also a profit-sharingprofit‑sharing portion of the 401(k) plan which provides for an annual discretionary contribution to the retirement account of each employee based in part on our profitability in a given year and on each participant'sparticipant’s annual compensation.  The contribution amount granted each year is on a discretionary basis and there is no set formula used by the Compensation Committee. For 2015,2018, the Compensation Committee elected not to make a discretionary profit sharing contribution. In February 2016, the Board approved increasing the matching contribution on elective deferrals to eligible participants to an amount equal to 3% of each participants' salary.

Deferred Compensation.We sponsor an executive deferred compensation plan (the "Executive“Executive Deferred Compensation Plan"Plan”), which provides a means for certain executives to voluntarily defer all or a portion of their salary and/or bonus, if any, without regard to the statutory limitations applicable to tax-qualifiedtax‑qualified plans, such as our 401(k) plan.  The Executive Deferred Compensation Plan provides for participant deferrals, company matching contributions and discretionary employer profit-sharingprofit‑sharing contributions.  A company matching contribution is credited to the plan on behalf of a participant when the participant elects to defer the maximum amount permitted under the 401(k) plan (including catch-upcatch‑up contributions, if applicable) and keeps that level of deferral for the entire plan year.   The company matching contribution is an amount up to 3%, provided at least a 6% deferral was met, of the participant'sparticipant’s combined base salary and bonuses, less any matching contribution paid to the 401(k) plan on the participant'sparticipant’s behalf.  The determination of whether a profit-sharingprofit‑sharing contribution is made and in what amount is entirely at the Compensation Committee'sCommittee’s discretion and there is no set formula.  Participants are permitted to make hypothetical investments in publicly-tradedwith respect to their account balances.  The participants may select such hypothetical investments from an array of publicly‑traded mutual funds that are held in an insurance company separate account with respect to the deferrals and our contributions credited to their accounts under the Executive Deferred Compensation Plan.account.  Participants may elect to receive their Executive Deferred Compensation Plan balance in a lump sum or in installments.  Participants may make a withdrawal from the plan during their employment in the event of hardship as approved by the plan'splan’s administrator.  The plan is administered through an independent service provider. Messrs. Eccher, CheathamCollins and Gottschalk currently have account balances under the Executive Deferred Compensation Plan.

Perquisites and Other Benefits.We provide general and customary benefit programs to executive officers and other employees.  Benefits offered to executives are intended to serve a different purpose than base salary, bonus, cash incentive and equity incentive awards.  While the benefits offered are competitive with the marketplace and help attract and retain executives, the benefits also provide financial security for employees for retirement as well as in the event of illness, disability or death.  The benefits we offer to executive officers are generally those offered to other employees with some variation to promote tax efficiency and replacement of benefit opportunities lost to regulatory limits although there are some additional perquisites that may only be offered to executive officers.  Because of the nature of the benefits offered, the Compensation Committee normally does not adjust the level of benefits offered on a year-to-yearyear‑to‑year basis.  We will continue to offer benefits, the amount of which shall be determined from time-to-timetime‑to‑time in the sole discretion of the Compensation Committee.

The following table summarizes the benefits and perquisites we do and do not provide as well as identifies those employees that may be eligible to receive them:

It is our belief that perquisites for executive officers should be very limited in scope and value.  Due to this philosophy, we have generally provided very nominal benefits to executives that are not available to full-time full‑time

employees, and we plan to continue this approach in the future.  We do provide country club memberships to certain executives and managers in the ordinary course of business to give them the opportunity to bring in and recruit new business opportunities.  These individuals are eligible to use the club membership for their own personal use.  Additionally, we provide Mr.Messrs. Eccher, Adams, Collins and Pilmer with an automobile allowance to enable himthem to visit our banking locations on a regular basis as well as to call on our customers.  We have disclosed the value of all perquisites to named executive officers in the Summary Compensation Table even if they fall below the disclosure thresholds under the SEC rules.  We will continue to offer perquisites, the amount of which shall be determined from time-to-timetime‑to‑time in the sole discretion of the Compensation Committee.

Severance and Change in Control Arrangements

Employment Agreements and Compensation and Benefits Assurance Agreements.    In connection withUnder his appointment as President and Chief Executive Officer of the Company,employment agreement, we provide Mr. Eccher entered into an employment agreement effective as of January 1, 2015 which provides forwith certain “double trigger” severance benefits in the event of anhis involuntary termination following a change in control, as well as salary continuation following certain other involuntary terminations.  The Company hasWe have also entered into Compensation and Benefits Assurance Agreements with each of the remainingour other named executive officers which also provide for“double trigger” severance benefits in the event of a qualifying termination following a change in control.  We believe these agreements help us recruit and retain executives with the experience, skills, knowledge and background needed to achieve our business goals and strategy.  For a detailed description of the severance and change in control benefits applicable to our named executive officers, see the discussion below under “Potential Payments Upon Termination or Change in Control.”

Acceleration of Equity Awards.All employees, including theour named executive officers, who receive equity awards under our Equity Incentive Plan will immediately vest in any unvested equity awards held by such employees upon the occurrence of a change in control if (i) the equity plan and the respective awards are not assumed by the surviving entity or (ii) the plan and the respective awards are assumed by the surviving entity but the individual is terminated without cause or resigns for good reason.  There are no unvested awards under our 2008 Plan. Additionally, under the terms of the Employment Agreement and Assurance Agreements noted above and Employment Agreements discussed above,described in greater detail below, all equity awards held by a named executive officer will become vested and exercisable upon a qualifying termination following a change in control.

No Tax Gross-Ups.Gross‑Ups.      Under Section 280G of the Internal Revenue Code (the "Code"), an executive may be subject toWe do not provide excise taxestax gross‑ups on certain benefits received in relation to aunder any change in control provisions or other agreements.  All of the Company. Mr. Eccher'sour named executive officers currently have employment agreement providesagreements or Compensation and Benefits Assurance Agreements that provide that in the event hethe officer would be subject to excise tax for any amounts payable under thesuch agreement, the amounts to be paid shallwill be reduced to such lesser extent that would result in no portion of such amounts being subject to excise taxes. The remaining named executive officers are entitled to a gross up payment in an amount to cover the full cost of any excise tax and their state and federal income and payroll taxes per the terms of their respective Assurance Agreements in the event any portion of their severance benefits, or other payments from the Company, would constitute an excess parachute payment for which excise tax is due.

Compensation Process

The Compensation Committee has overall responsibility for evaluating the compensation plans, policies and programs relating to our executive officers.  Further, as required by the rules established by Treasury, guidance issued by the Federal Reserve and other financial institution regulatory agencies, and the SEC'sSEC’s guidance regarding risk associated with compensation arrangements (each as described more fully below), the Compensation Committee is also responsible for a more expansive risk review with respect to most of the compensation plans, policies and programs maintained for our employees.

During 2015,2018, the Compensation Committee convened in February and October.March. Mr. Palmer servedLadowicz, as Chairman of the Compensation Committee, through his retirement from the board of directors in October 2015, at which time he was succeeded by Mr. Ladowicz. Mr. Palmer and Mr. Ladowicz also met, as needed, with internal staff members to compile compensation information for this proxy statement.  The Compensation Committee also met in February 2016and again in March 2019 to approve salaries, incentive plans and performance metrics for 2016.2019, as well as approving officer incentives earned during 2018.

Role of Compensation Consultant.The Compensation Committee'sCommittee’s charter gives it the authority to delegate its responsibility to members or subcommittees of the Compensation Committee.  Also, the charter gives the Compensation Committee the authority to hire outside consultants to further its objectives and responsibilities.  In prior years, the Compensation Committee has retained ChaseCompGroup LLC to provide services in connection with a review and analysis of compensation paid to our named executive officers and board of directors.  In keeping with the Compensation Committee'sCommittee’s philosophy of comparing our compensation with that of the localcompetitive marketplace on an

annual basis, the Compensation Committee retained ChaseCompGroup LLC in 20152018 to provide an updated market analysis of our executive compensation program. The Compensation Committee expects to retain ChaseCompGroup LLC again in 2016. Additionally, the Compensation Committee has retained Willis Towers Watson in connection with matters related to equity compensation, including the amendment of our Incentive Plan discussed below.

Role of Executive Officers.The Compensation Committee relies upon the input of management, when carrying out its responsibilities in establishing executive compensation.  The Compensation Committee relies on Mr. Eccher'sEccher’s input in establishing compensation for our named executive officers other than himself.  Management provides the Compensation Committee with evaluations as to employee performance, guidance on establishing performance targets and objectives and recommends salary levels and equity awards.  The Compensation Committee also consults with management on matters that are relevant to executive compensation and benefit plans where board or stockholder action is expected, including the adoption of new plans or the amendment of existing plans.  Finally, the Compensation Committee consults with our management, specifically the Bank'sBank’s Senior Risk Officer, in completing the risk review with respect to employee compensation plans. A risk review was performed in February 2016.  No executive officer participates in any recommendation, discussion or decision regarding his or her own compensation.

Peer Group.Market pay practices are one of many factors we consider in setting executive pay levels and designing compensation programs. Information on pay levels and practices is gathered forfrom a group of publicly traded companies selected based on their business focus, scope and location of operations, size and other considerations.  The Company'sCompany’s peer group of 16 financial institutions was jointly presented by ChaseCompGroup LLC and management and approved by the Compensation Committee.  The group is

periodically reviewed, with changes made to reflect merger and acquisition activity, financial situation and development, and other considerations.  The institutions included in the peer group for 2018 include:

Analysis of 20152018 Compensation

This section describes the decisions made by the Compensation Committee with respect to the compensation for theour named executive officers for 2015 and 2016.2018.

            The following is a brief summary of the Compensation Committee's compensation decisions for 2015 and 2016:

•

for 2015, conservative merit increases in base salary were granted to our named executive officers (other than Mr. Eccher) in keeping with the conservative compensation guidelines established for the organization;

•

$460,409 cash bonus payments were earned or awarded to our named executive officers with respect to 2015 performance; and



•

benefits and perquisites remained substantially similar in 2015 compared to prior years and we expect that will continue through 2016.

Base Salary.We annually review the base salaries of the named executive officers to determine whether or not they will be adjusted, as described above.  The salaries for 2015,2018, determined by the Compensation Committee at the beginning of 2015,2018, are set forth in the Summary Compensation Table below. In determining thesebase salary levels, we generally considered the following:

2019.   In determining the base salaries for 2016,2019, we considered the same general factors discussed above including the continuing general slowdowngrowth in the economy and growth of our earnings, return on average assets and overall assets.

For 2019 and 2018, the Compensation Committee increased Mr. Eccher’s base salary by 6.0% and 5.0%, respectively, based on overall company and his individual performance. Mr. Adam’s base salary was increased by 4.0% and 2.75% for 2019 and 2018, respectively, due to overall company performance and successful completion of the 2018 acquisition of Greater Chicago Financial Corp(“GCFC”)./ABC Bank.  Mr. Collin’s base salary was increased by 2.75% in both 2019 and 2018, due to overall company performance and successful completion of the GCFC/ABC Bank acquisition.  .Mr. Pilmer also received merit increases in base salary of 2.8% and 3.0% in 2019 and 2018, respectively, due primarily to commercial loan and commercial treasury management growth.

Annual Cash Bonus.Incentive Payments.      Based onAs discussed above, under our namedIncentive Plan, the Compensation Committee, in consultation with our Chief Executive Officer, selects key performance objectives, which will be used to determine the actual incentive cash payment to be awarded to our executive officers'officers upon the achievement of the goals for earning a cash bonus established byselected performance objectives.  In addition, under the Incentive Plan, the Compensation Committee we awarded cash bonusesalso determines each executive officer’s target incentive opportunity, expressed as a percentage of base salary.

For 2018, the Compensation Committee set forth below:the target potential incentive payment, expressed as a percentage of base salary, as follows:

For 2018, the Compensation Committee selected five performance objectives, as identified in the following table (and described in more detail below), and assigned a weight for each performance objective, stated as a percentage of the total target incentive payment.

The components designatedperformance objectives chosen by the Compensation Committee and the target percentage of salary that the named executive officers were eligible to earnassigned weight for 2015each objective for 2018 performance were as follows:

The Company consideredCompensation Committee established threshold, target and maximum performance levels and weights for each selected corporate goal.  Threshold represents the followingminimum level of performance metrics in determinationat which, if achieved, a payment is earned on each corporate goal.  If performance is below the threshold level for any particular corporate goal, no payment will be earned; however, payment will be earned for other corporate objectives that are achieved at least at a threshold level of performance.  Maximum represents the maximum level of performance at which, if achieved, a maximum payment is earned on each corporate goal. If performance exceeds the maximum level for any corporate goal, no further incentive above the maximum incentive for such corporate goal is earned.  Actual performance between threshold, target and maximum performance levels will be interpolated to determine the amount of payment based on relative achievement of the corporate objectives.

How we defined each of these corporate objects is set forth below.
