 2017 ANNUAL REPORT AT THE CORE

COREVALUES

2017 was a landmark year for Mercantile 
Bank Corporation. 

Twenty years ago, in December 1997, Mercantile Bank opened its doors  

in downtown Grand Rapids, Michigan. From that successful beginning,  

we have continued to grow and now maintain a market presence in a  

significant portion of the state of Michigan. We marked this anniversary  

with another strong year of profitability, growth, quality and efficiency.  

While we celebrate the accomplishments of 2017, we also look forward  
to the future with great anticipation. 

3 MERCANTILE BANK CORPORATION 

As our company has continued to 

grow and evolve along with the entire 

financial services industry, our core 

values remain the same. It is these 

core values that allow Mercantile to 

be the bank of choice for so many 

businesses and individuals who are 

seeking a knowledgeable and caring 

financial partner on whom they can rely. 

Understanding our clients’ needs and 

building long-term relationships with 

them are the approaches to banking  

that we have embraced since our 

beginning. Our staff also has a sharp 

focus on maintaining a culture of 

excellence in all that we do. 

These are the foundational 

building blocks for the 

way we do business, 

and they provide 

maximum benefit 

to all of our 

constituents—

clients, employees, 

communities and 

shareholders.

of nearly 8%, reflecting balanced 

expansion in our loan portfolio. 

Business loans were up $138 million, 

with growth in commercial, industrial 

and commercial real estate loans.  

The retail mortgage portfolio grew 

$59.3 million, reflecting the very 

positive results of one of our major

includes payment cards, human 

capital management, receivables 

and payables solutions, and remote 

deposit, are attractive offerings for  

our client acquisition activities. 

Mercantile expanded its footprint during 2017 with a new

team of bankers brought to our company to help us open  

this office and their ability to deliver relationship banking  

to prospective clients in southeast Michigan.

FUTURECORE

We remain energized about the economic 
rebound we have witnessed in the state  
of Michigan over the last several years. 

Unemployment rates and job growth in Michigan now track  

closely with the national averages, and in some of our markets,  

the economic metrics are among  

the strongest in the nation.  

Michigan’s median home prices 

continue to rise. The result is  

a solid operating environment 

for clients and our company.

The financial services industry continues 

to undergo significant change, fueled by 

advancements in technology. We are excited 

about the opportunities these advancements  

will provide to develop new and innovative

as entrepreneurial with the ability to add  

value as they pursue financial success. With  

this approach to business, we continually  
strive for growth and further improvement  

to our company’s performance. We are  

thankful for the confidence and support of  

our shareholders, and we look forward to a  
bright future as Michigan’s Community Bank®.

Item 1.  Business. 

The Company 

PART I 

Mercantile Bank Corporation is a registered bank holding company under the Bank Holding Company Act of 
1956, as amended (the “Bank Holding Company Act”).  Unless the text clearly suggests otherwise, references to “us,” 
“we,” “our,” or “the company” include Mercantile Bank Corporation and its wholly-owned subsidiaries.  As a bank holding 
company, we are subject to regulation by the Board of Governors of the Federal Reserve System (the “Federal Reserve 
Board”).  We were organized on July 15, 1997, under the laws of the State of Michigan, primarily for the purpose of 
holding all of the stock of Mercantile Bank of Michigan (“our bank”), and of such other subsidiaries as we may acquire or 
establish. Our bank commenced business on December 15, 1997.  During the third quarter of 2013, we filed an election to 
become a financial holding company, which election became effective April 14, 2014. 

Mercantile Insurance Center, Inc. (“our insurance company”), a subsidiary of our bank, commenced operations 

during 2002 to offer insurance products.  Mercantile Bank Real Estate Co., L.L.C., (“our real estate company”), a 
subsidiary of our bank, was organized on July 21, 2003, principally to develop, construct and own our facility in downtown 
Grand Rapids which serves as our bank’s main office and Mercantile Bank Corporation’s headquarters. 

Our expenses have generally been paid using cash dividends from our bank.  Our principal source of future 

operating funds is expected to be dividends from our bank. 

Firstbank Corporation Merger 

We completed our merger with Firstbank Corporation (“Firstbank”), a Michigan corporation with approximately 
$1.5 billion in total assets and 46 branch locations, into Mercantile Bank Corporation as of June 1, 2014 (“Merger Date”). 
The merger substantially expanded our geographic footprint and increased the size of our balance sheet.  

In conjunction with the completion of the merger, Mercantile assumed the obligations of Firstbank Capital Trust I, 

Firstbank Capital Trust II, Firstbank Capital Trust III and Firstbank Capital Trust IV, all of which are business trust 
subsidiaries formed to issue trust preferred securities.  At the Merger Date, Firstbank had two Michigan-chartered bank 
subsidiaries that were consolidated into Mercantile Bank of Michigan effective June 30, 2014. 

Our Bank 

Our bank is a state banking company that operates under the laws of the State of Michigan, pursuant to a charter 

issued by the Michigan Department of Insurance and Financial Services.  Our bank’s deposits are insured to the maximum 
extent permitted by law by the Federal Deposit Insurance Corporation (“FDIC”).  Our bank, through its 49 office locations, 
provides commercial banking services primarily to small- to medium-sized businesses and retail banking services.  Our 
bank’s main office is located in Grand Rapids, and our operations are centered around the West and Central portions of 
Michigan, with branch office locations in Alma, Belding, Cadillac, Canadian Lakes, Clare, Comstock Park, DeWitt, 
Fairview, Grand Rapids, Hale, Hastings, Holland, Howard City, Ionia, Ithaca, Kalamazoo, Kentwood, Lakeview, Lansing, 
Lowell, Merrill, Mt. Pleasant, Paw Paw, Portage, Remus, Rose City, Shepherd, St. Charles, St. Helen, St. Johns, Vestaburg, 
West Branch, and Wyoming.  We expanded into Southeast Michigan in 2017, opening a banking office in Troy during the 
first quarter. 

Our bank makes secured and unsecured commercial, construction, mortgage and consumer loans, and accepts 

checking, savings and time deposits.  Our bank owns 49 automated teller machines ("ATM") located at certain of our office 
locations and at one off-site location that participate in the ACCEL/EXCHANGE and PLUS regional network systems, as 
well as other ATM networks throughout the country.  Our bank also enables customers to conduct certain loan and deposit 
transactions by personal computer and through mobile applications.  Courier service is provided to certain commercial 
customers, and safe deposit facilities are available at a vast majority of our office locations.  Our bank does not have trust 
powers.  

2 

Our Insurance Company 

Our insurance company acquired an existing shelf insurance agency effective April 15, 2002.  An Agency and 

Institution Agreement was entered into among our insurance company, our bank and Hub International for the purpose of 
providing programs of mass marketed personal lines of insurance.  Insurance product offerings include private passenger 
automobile, homeowners, personal inland marine, boat owners, recreational vehicle, dwelling fire, umbrella policies, small 
business and life insurance products, all of which are provided by and written through companies that have appointed Hub 
International as their agent.  To date, we have not provided the insurance products noted above and currently have no plans 
to do so. 

Our Real Estate Company 

Our real estate company was organized on July 21, 2003, principally to develop, construct and own our facility in 

downtown Grand Rapids that serves as our bank’s main office and Mercantile Bank Corporation’s headquarters.  This 
facility was placed into service during the second quarter of 2005.  Our real estate company is 99% owned by our bank and 
1% owned by our insurance company. 

Our Trusts 

We have five business trusts that are wholly-owned subsidiaries of Mercantile, four of which were assumed by 
Mercantile in conjunction with the merger with Firstbank. Each of the trusts was formed to issue preferred securities that 
were sold in private sales, as well as selling common securities to Mercantile.  The proceeds from the preferred and 
common securities sales were used by the trusts to purchase floating rate notes issued by Mercantile.  The rates of interest, 
interest payment dates, call features and maturity dates of each floating rate note are identical to its respective preferred 
securities.  The net proceeds from the issuance of the floating rate notes were used for a variety of purposes, including 
contributions to our bank as capital to provide support for asset growth and the funding of stock repurchase programs and 
certain acquisitions.  The only significant assets of our trusts are the floating rate notes, and the only significant liabilities of 
our trusts are the preferred securities.  The floating rate notes are categorized on our Consolidated Balance Sheets as 
subordinated debentures, and the interest expense is recorded on our Consolidated Statements of Income under interest 
expense on other borrowings. 

Effect of Government Monetary Policies 

Our earnings are affected by domestic economic conditions and the monetary and fiscal policies of the United 

States Government, its agencies, and the Federal Reserve Board. The Federal Reserve Board’s monetary policies have had, 
and will likely continue to have, an important impact on the operating results of commercial banks through its power to 
implement national monetary policy in order to, among other things, curb inflation, maintain or encourage employment, 
and mitigate economic recessions.  The policies of the Federal Reserve Board have a major effect upon the levels of bank 
loans, investments and deposits through its open market operations in United States Government securities, and through its 
regulation of, among other things, the discount rate on borrowings of member banks and the reserve requirements against 
member bank deposits.  Our bank maintains reserves directly with the Federal Reserve Bank of Chicago to the extent 
required by law.  It is not possible to predict the nature and impact of future changes in monetary and fiscal policies. 

Regulation and Supervision 

Banks and bank holding companies, among other financial institutions, are regulated under federal and state law.  
These include, among others, minimum capital requirements, state usury laws, state laws relating to fiduciaries, the Dodd-
Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”), the Truth in Lending Act, the Truth in

Board, the FDIC, the Michigan Department of Insurance and Financial Services, the Internal Revenue Service and state 
taxing authorities.  The effect of such statutes, regulations and policies, and any changes thereto, can be significant and

As a registered bank holding company under the Bank Holding Company Act, we are required to file an annual 

report with the Federal Reserve Board and such additional information as the Federal Reserve Board may require.  We are 
also subject to examination by the Federal Reserve Board. 

The Bank Holding Company Act limits the activities of bank holding companies to banking and the management 
of banking organizations, and to certain non-banking activities.  The permitted non-banking activities include those limited 
activities that the Federal Reserve Board found, by order or regulation as of the day prior to enactment of the Gramm-
Leach-Bliley Act, to be so closely related to banking as to be a proper incident to banking.  These permitted non-banking 
activities include, among other things: operating a mortgage company, finance company, or factoring company; performing 
certain data processing operations; providing certain investment and financial advice; acting as an insurance agent for 
certain types of credit-related insurance; leasing property on a full-payout, nonoperating basis; and providing discount 
securities brokerage services for customers.  Neither we nor any of our subsidiaries engage in any of the non-banking 
activities listed above. 

On April 14, 2014, our election to become a financial holding company, as permitted by the Bank Holding 

Company Act, as amended by Title I of the Gramm-Leach-Bliley Act, was accepted by the Federal Reserve Board.  In 
order to continue as a financial holding company, we and our bank must satisfy statutory requirements regarding 
capitalization, management and compliance with the Community Reinvestment Act.  As a financial holding company, we 
are permitted to engage in a broader range of activities under the Bank Holding Company Act than are permitted to bank 
holding companies.  Those expanded activities include any activity which the Federal Reserve Board (in certain instances 
in consultation with the Department of the Treasury) determines, by order or by regulation, to be financial in nature or 
incidental to such financial activity, or to be complementary to a financial activity, and not to pose a substantial risk to the 
safety and soundness of depository institutions or the financial system generally.  Such expanded activities include, among 
others: insuring, guaranteeing, or indemnifying against loss, harm, damage, illness, disability or death, or issuing annuities, 
and acting as principal, agent or broker for such purposes; providing financial, investment or economic advisory services, 
including advising a mutual fund; and underwriting, dealing in, or making a market in securities.  While our insurance 
company is permitted to engage in the insurance agency activities described above by virtue of our financial holding 
company status, neither we nor any of our subsidiaries currently engages in the expanded activities. 

Our bank is subject to restrictions imposed by federal and state law and regulations.  Among other things, these 

restrictions apply to any extension of credit to us or to our other subsidiaries, to securities borrowing or lending, 
derivatives, and repurchase transactions with us or our other subsidiaries, to investments in stock or other securities that we 
issue, to the taking of such stock or securities as collateral for loans to any borrower, and to acquisitions of assets or 
services from, and sales of certain types of assets to, us or our other subsidiaries.  Michigan banking laws place restrictions 
on various aspects of banking, including branching, payment of dividends, loan interest rates and capital and surplus 
requirements.  Federal law restricts our ability to borrow from our bank by limiting the aggregate amount we may borrow 
and by requiring that all loans to us be secured in designated amounts by specified forms of collateral. 

With respect to the acquisition of banking organizations, we are generally required to obtain the prior approval of 
the Federal Reserve Board before we can acquire all or substantially all of the assets of any bank, or acquire ownership or 
control of any voting shares of any bank or bank holding company, if, after the acquisition, we would own or control more 
than 5% of the voting shares of the bank or bank holding company.  Acquisitions of banking organizations across state 
lines are subject to restrictions imposed by federal and state laws and regulations. 

The scope of regulations and supervision of various aspects of our business have expanded as a result of the 

adoption in July, 2010 of the Dodd-Frank Act, and may continue to expand as the result of implementing regulations being 
adopted by federal regulators.  However, the new federal administration has indicated its intention to repeal or amend 
certain aspects of the Dodd-Frank Act and the precise scope of those changes has not yet been determined.  For additional 
information on this legislation and its potential impact, refer to the Risk Factor entitled “The effect of financial services 
legislation and regulations remains uncertain” in Item 1A- Risk Factors in this Annual Report. 

 Employees 

As of December 31, 2017, we employed 584 full-time and 117 part-time persons.  Management believes that 

relations with employees are good.

Lending Policy 

As a routine part of our business, we make loans to businesses and individuals located within our market areas.  

Our lending policy states that the function of the lending operation is twofold: to provide a means for the investment of 
funds at a profitable rate of return with an acceptable degree of risk, and to meet the credit needs of the creditworthy 
businesses and individuals who are our customers.  We recognize that in the normal business of lending, some losses on 
loans will be inevitable and should be considered a part of the normal cost of doing business. 

Our lending policy anticipates that priorities in extending loans will be modified from time to time as interest 

rates, market conditions and competitive factors change.  The policy sets forth guidelines on a nondiscriminatory basis for 
lending in accordance with applicable laws and regulations.  The policy describes various criteria for granting loans, 
including the ability to pay; the character of the customer; evidence of financial responsibility; purpose of the loan; 
knowledge of collateral and its value; terms of repayment; source of repayment; payment history; and economic conditions. 

The lending policy further limits the amount of funds that may be loaned against specified types of real estate 

collateral. For certain loans secured by real estate, the policy requires an appraisal of the property offered as collateral by a 
state certified independent appraiser.  The policy also provides general guidelines for loan to value for other types of 
collateral, such as accounts receivable and machinery and equipment.  In addition, the policy provides general guidelines as 
to environmental analysis, loans to employees, executive officers and directors, problem loan identification, maintenance of 
an allowance for loan losses, loan review and grading, mortgage and consumer lending, and other matters relating to our 
lending practices. 

The Board of Directors has delegated significant lending authority to officers of our bank.  The Board of Directors 

believes this empowerment, supported by our strong credit culture and the significant experience of our commercial 
lending staff, enables us to be responsive to our customers.  The loan policy specifies lending authority for our lending 
officers with amounts based on the experience level and ability of each lender.  Our loan officers and loan managers are 
able to approve loans up to $1.0 million and $2.5 million, respectively.  We have established higher approval limits for our 
bank’s Senior Lender, President and Chief Executive Officer, and Executive Chairman of the Board ranging from $4.0 
million up to $10.0 million.  These lending authorities, however, are typically used only in rare circumstances where timing 
is of the essence.  Generally, loan requests exceeding $2.5 million require approval by the Officers Loan Committee, and 
loan requests exceeding $7.5 million, up to the legal lending limit of approximately $80.2 million, require approval by the 
bank’s Board of Directors.  We apply an in-house lending limit that is significantly less than our bank’s legal lending limit. 

Provisions of recent legislation, including the Dodd-Frank Act, when fully implemented by regulations to be 

adopted by federal agencies, may have a significant impact on our lending policy, especially in the areas of single-family 
residential real estate and other consumer lending.  For additional information on this legislation and its potential impact, 
refer to the Risk Factor entitled “The effect of financial services legislation and regulations remains uncertain” in Item 1A- 
Risk Factors in this Annual Report. 

Lending Activity 

Commercial Loans. Our commercial lending group originates commercial loans primarily in our market areas.  
Our commercial lenders have extensive commercial lending experience, with most having at least ten years’ experience.  
Loans are originated for general business purposes, including working capital, accounts receivable financing, machinery 
and equipment acquisition, and commercial real estate financing, including new construction and land development. 

Working capital loans are often structured as a line of credit and are reviewed periodically in connection with the 

borrower’s year-end financial reporting.  These loans are generally secured by substantially all of the assets of the borrower 
and have a floating interest rate tied to the Wall Street Journal Prime Rate or 30-day Libor Rate. Loans for machinery and 
equipment purposes typically have a maturity of three to five years and are fully amortizing, while commercial real estate 
loans are usually written with a five-year maturity and amortize over a 10- to 20-year period.  Commercial loans typically 
have an interest rate that is fixed to maturity or is tied to the Wall Street Journal Prime Rate or 30-day Libor Rate. 

5 

 
 
 
  
  
  
  
  
  
  
  
  
 
 
 
 
 
We evaluate many aspects of a commercial loan transaction in order to minimize credit and interest rate risk. 

Underwriting includes an assessment of the management, products, markets, cash flow, capital, income and collateral of the 
borrowing entity.  This analysis includes a review of the borrower’s historical and projected financial results.  Appraisals 
are generally required to be performed by certified independent appraisers where real estate is the primary collateral, and in 
some cases, where equipment is the primary collateral. In certain situations, for creditworthy customers, we may accept 
title reports instead of requiring lenders’ policies of title insurance. 

 Commercial real estate lending involves more risk than residential lending because loan balances are typically 

greater and repayment is dependent upon the borrower’s business operations.  We attempt to minimize the risks associated 
with these transactions by generally limiting our commercial real estate lending to owner-operated properties and to owners 
of non-owner occupied properties who have an established profitable history and satisfactory tenant structure.  In many 
cases, risk is further reduced by requiring personal guarantees, limiting the amount of credit to any one borrower to an 
amount considerably less than our legal lending limit and avoiding certain types of commercial real estate financings. 

We have no material foreign loans, and only limited exposure to companies engaged in energy producing and 

agricultural-related activities. 

Single-Family Residential Real Estate Loans. We originate single-family residential real estate loans in our market 
areas, generally according to secondary market underwriting standards.  Loans not conforming to those standards are made 
in certain circumstances.  Single-family residential real estate loans provide borrowers with a fixed or adjustable interest 
rate with terms up to 30 years and are generally sold to certain investors. 

Our bank has a home equity line of credit program.  Home equity lines of credit are generally secured by either a 
first or second mortgage on the borrower’s primary residence.  The program provides revolving credit at a rate tied to the 
Wall Street Journal Prime Rate. 

Consumer Loans. We originate various types of consumer loans, including new and used automobile and boat 

loans, credit cards and overdraft protection lines of credit for our checking account customers.  Consumer loans generally 
have shorter terms and higher interest rates and usually involve more credit risk than single-family residential real estate 
loans because of the type and nature of the collateral.  

We believe our consumer loans are underwritten carefully, with a strong emphasis on the amount of the down 

payment, credit quality, employment stability and monthly income of the borrower.  These loans are generally repaid on a 
monthly repayment schedule with the source of repayment tied to the borrower’s periodic income.  In addition, consumer 
lending collections are dependent on the borrower’s continuing financial stability, and are thus likely to be adversely 
affected by job loss, illness and personal bankruptcy. In many cases, repossessed collateral for a defaulted consumer loan 
will not provide an adequate source of repayment of the outstanding loan balance because of depreciation of the underlying 
collateral.  We believe that the generally higher yields earned on consumer loans compensate for the increased credit risk 
associated with such loans, and that consumer loans are important to our efforts to serve the credit needs of the 
communities and customers that we serve. 

Loan Portfolio Quality 

We utilize a comprehensive grading system for our commercial loans, whereby all commercial loans are graded on 
a ten grade rating system.  The rating system utilizes standardized grade paradigms that analyze several critical factors such 
as cash flow, operating performance, financial condition, collateral, industry condition and management.  All commercial 
loans are graded at inception and reviewed at various intervals.  

Our independent loan review program is primarily responsible for the administration of the grading system and 

ensuring adherence to established lending policies and procedures.  The loan review program is an integral part of 
maintaining our strong asset quality culture.  The loan review function works closely with senior management, although it 
functionally reports to the Board of Directors.  Using a risk-based approach to selecting credits for review, our loan review 
program has covered approximately 65% to 75% of total commercial loans outstanding during the past three years.  In 
addition, a random sampling of retail loans is reviewed each quarter.  Our watch list credits are reviewed monthly by our 
Board of Directors and our Watch List Committee, the latter of which is comprised of senior level officers from the 
administration, lending and loan review functions.

 Loans are placed in a nonaccrual status when, in our opinion, uncertainty exists as to the ultimate collection of all 

principal and interest.  As of December 31, 2017, loans placed in nonaccrual status totaled $7.1 million, or 0.3% of total 
loans, compared to $5.9 million, or 0.2% of total loans, at December 31, 2016.  No loans were past due 90 days or more 
and still accruing interest at year-end 2017 or 2016. 

Additional detail and information relative to the loan portfolio is incorporated by reference to Management’s 

Discussion and Analysis of Financial Condition and Results of Operations (“Management’s Discussion and Analysis”) and 
Note 4 of the Notes to Consolidated Financial Statements in this Annual Report. 

Allowance for Loan Losses 

In each accounting period, we adjust the allowance to the amount we believe is necessary to maintain the 

allowance at an adequate level.  Through the loan review and credit departments, we establish specific portions of the 
allowance based on specifically identifiable problem loans.  The evaluation of the allowance is further based on, but not 
limited to, consideration of the internally prepared Allowance Analysis, loan loss migration analysis, composition of the 
loan portfolio, third party analysis of the loan administration processes and portfolio, and general economic conditions. 

The Allowance Analysis applies reserve allocation factors to non-impaired outstanding loan balances, the result of 

which is combined with specific reserves to calculate an overall allowance amount.  For non-impaired commercial loans, 
reserve allocation factors are based on the loan ratings as determined by our standardized grade paradigms and by loan 
purpose.  Our commercial loan portfolio is segregated into five classes: 1) commercial and industrial loans; 2) vacant land, 
land development and residential construction loans; 3) owner occupied real estate loans; 4) non-owner occupied real estate 
loans; and 5) multi-family and residential rental property loans.  The reserve allocation factors are primarily based on the 
historical trends of net loan charge-offs through a migration analysis whereby net loan losses are tracked via assigned 
grades over various time periods, with adjustments made for environmental factors reflecting the current status of, or recent 
changes in, items such as: lending policies and procedures; economic conditions; nature and volume of the loan portfolio; 
experience, ability and depth of management and lending staff; volume and severity of past due, nonaccrual and adversely 
classified loans; effectiveness of the loan review program; value of underlying collateral; lending concentrations; and other 
external factors, including competition and regulatory environment.  Adjustments for specific lending relationships, 
particularly impaired loans, are made on a case-by-case basis.  Non-impaired retail loan reserve allocations are determined 
in a similar fashion as those for non-impaired commercial loans, except that retail loans are segmented by type of credit and 
not a grading system.  We regularly review the Allowance Analysis and make adjustments periodically based upon 
identifiable trends and experience. 

A migration analysis is completed quarterly to assist us in determining appropriate reserve allocation factors for 

non-impaired loans.  Our migration takes into account various time periods; however, at year-end 2017 we placed most 
weight on the period starting December 31, 2010 through December 31, 2017.  We believe this period represents an 
appropriate range of economic conditions, and that it provides for an appropriate basis in determining reserve allocation 
factors given current economic conditions and the general market consensus of economic conditions in the near future. 

Although the migration analysis provides an accurate historical accounting of our net loan losses, it is not able to 

fully account for environmental factors that will also very likely impact the collectability of our loans as of any quarter-end 
date.  Therefore, we incorporate the environmental factors as adjustments to the historical data.  Environmental factors 
include both internal and external items.  We believe the most significant internal environmental factor is our credit culture 
and the relative aggressiveness in assigning and revising commercial loan risk ratings, with the most significant external 
environmental factor being the assessment of the current economic environment and the resulting implications on our loan 
portfolio. 

The primary risk elements with respect to commercial loans are the financial condition of the borrower, the 
sufficiency of collateral, and the timeliness of scheduled payments.  We have a policy of requesting and reviewing periodic 
financial statements from commercial loan customers, and we have a disciplined and formalized review of the existence of 
collateral and its value.  The primary risk element with respect to each residential real estate loan and consumer loan is the 
timeliness of scheduled payments.  We have a reporting system that monitors past due loans and have adopted policies to 
pursue creditor’s rights in order to preserve our collateral position.  

Additional detail regarding the allowance is incorporated by reference to Management’s Discussion and Analysis 

and Note 4 of the Notes to Consolidated Financial Statements included in this Annual Report.

Investments 

Bank Holding Company Investments. The principal investments of our bank holding company are the investments in 

the common stock of our bank and the common securities of our trusts.  Other funds of our bank holding company may be 
invested from time to time in various debt instruments. 

 Subject to the limitations of the Bank Holding Company Act and the “Volcker Rule”, we are also permitted to 

make portfolio investments in equity securities and to make equity investments in subsidiaries engaged in a variety of non-
banking activities, which include real estate-related activities such as community development, real estate appraisals, 
arranging equity financing for commercial real estate, and owning and operating real estate used substantially by our bank 
or acquired for its future use.  Our bank holding company has no plans at this time to make directly any of these equity 
investments at the bank holding company level. Our Board of Directors may, however, alter the investment policy at any 
time without shareholder approval. 

Our Bank’s Investments. Our bank may invest its funds in a wide variety of debt instruments and may participate 

in the federal funds market with other depository institutions.  Subject to certain exceptions, our bank is prohibited from 
investing in equity securities.  Among the equity investments permitted for our bank under various conditions and subject 
in some instances to amount limitations, are shares of a subsidiary insurance agency, mortgage company, real estate 
company, or Michigan business and industrial development company, such as our insurance company and our real estate 
company.  Under another such exception, in certain circumstances and with prior notice to or approval of the FDIC, our 
bank could invest up to 10% of its total assets in the equity securities of a subsidiary corporation engaged in the acquisition 
and development of real property for sale, or the improvement of real property by construction or rehabilitation of 
residential or commercial units for sale or lease.  Our bank has no present plans to make such an investment.  Real estate 
acquired by our bank in satisfaction of or foreclosure upon loans may be held by our bank for specified periods.  Our bank 
is also permitted to invest in such real estate as is necessary for the convenient transaction of its business.  Our bank’s 
Board of Directors may alter the bank’s investment policy without shareholder approval at any time. 

Additional detail and information relative to the securities portfolio is incorporated by reference to Management’s 

Discussion and Analysis and Note 3 of the Notes to Consolidated Financial Statements included in this Annual Report.  

Competition 

We face substantial competition in all phases of our operations from a variety of different competitors.  We 

compete for deposits, loans and other financial services with numerous Michigan-based and national and regional banks, 
savings banks, thrifts, credit unions and other financial institutions as well as from other entities that provide financial 
services.  Some of the financial institutions and financial service organizations with which we compete are not subject to 
the same degree of regulation as we are.  Many of our primary competitors have been in business for many years, have 
established customer bases, are larger, have substantially higher lending limits than we do, and offer larger branch networks 
and other services which we do not.  Most of these same entities have greater capital resources than we do, which, among 
other things, may allow them to price their services at levels more favorable to the customer and to provide larger credit 
facilities than we do.  Under specified circumstances (that have been modified by the Dodd-Frank Act), securities firms and 
insurance companies that elect to become financial holding companies under the Bank Holding Company Act may acquire 
banks and other financial institutions.  Federal banking law affects the competitive environment in which we conduct our 
business.  The financial services industry is also likely to become more competitive as further technological advances 
enable more companies to provide financial services.  We also face new competition as a result of our expansion into the 
Southeast Michigan marketplace.

Item 1A.  Risk Factors. 

The following risk factors could affect our business, financial condition or results of operations.  These risk factors 

should be considered in connection with evaluating the forward-looking statements contained in this Annual Report 
because they could cause the actual results and conditions to differ materially from those projected in forward-looking 
statements.  Before you buy our common stock, you should know that investing in our common stock involves risks, 
including the risks described below.  The risks that are highlighted here are not the only ones we face. If the adverse 
matters referred to in any of the risks actually occur, our business, financial condition or operations could be adversely 
affected. In that case, the trading price of our common stock could decline, and you may lose all or part of your investment. 

  Adverse changes in economic conditions or interest rates may negatively affect our earnings, capital and liquidity. 

The results of operations for financial institutions, including our bank, may be materially and adversely affected 

by changes in prevailing local and national economic conditions, including declines in real estate market values and the 
related declines in value of our real estate collateral, rapid increases or decreases in interest rates and changes in the 
monetary and fiscal policies of the federal government.  Our profitability is heavily influenced by the spread between the 
interest rates we earn on loans and investments and the interest rates we pay on deposits and other interest-bearing 
liabilities.  Substantially all of our loans are to businesses and individuals in Western, Central, and Southeastern Michigan, 
and any decline in the economy of these areas could adversely affect us.  Like most banking institutions, our net interest 
spread and margin will be affected by general economic conditions and other factors that influence market interest rates and 
our ability to respond to changes in these rates.  At any given time, our assets and liabilities may be such that they will be 
affected differently by a given change in interest rates. 

Significant declines in the value of commercial real estate could adversely impact us. 

Approximately 66% of our total commercial loans, or about 57% of our total loans, relate to commercial real 

estate.  Stressed economic conditions may reduce the value of commercial real estate and strain the financial condition of 
our commercial real estate borrowers, especially in the land development and non-owner occupied commercial real estate 
segments of our loan portfolio.  Those difficulties could adversely affect us and could produce losses and other adverse 
effects on our business. 

Market volatility may adversely affect us.  

The capital and credit markets may experience volatility and disruption.  In some cases, the markets have 

produced downward pressure on stock prices and credit availability for certain issuers without apparent regard to those 
issuers’ underlying financial strength.  Future levels of market disruption and volatility may have an adverse effect, which 
may be material, on our ability to access capital and on our business, financial condition and results of operations.

Our future success is dependent on our ability to compete effectively in the highly competitive banking industry. 

We face substantial competition in all phases of our operations from a variety of different competitors.  Our future 
growth and success will depend on our ability to compete effectively in this highly competitive environment.  We compete 
for deposits, loans and other financial services with numerous Michigan-based and national and regional banks, thrifts, credit 
unions and other financial institutions as well as other entities that provide financial services, including securities firms and 
mutual funds.  Some of the financial institutions and financial service organizations with which we compete are not subject 
to the same degree of regulation as we are.  Many of our competitors have been in business for many years, have established 
customer bases, are larger, have substantially higher lending limits than we do and offer larger branch networks and other 
services which we do not, including trust and international banking services.  Most of these entities have greater capital and 
other resources than we do, which, among other things, may allow them to price their services at levels more favorable to the 
customer and to provide larger credit facilities than we do.  This competition may limit our growth or earnings. Under 
specified circumstances (that have been modified by the Dodd-Frank Act), securities firms and insurance companies that 
elect to become financial holding companies under the Bank Holding Company Act may acquire banks and other financial 
institutions.  Federal banking law affects the competitive environment in which we conduct our business.  The financial 
services industry is also likely to become more competitive as further technological advances enable more companies to 
provide financial services.  These technological advances may diminish the importance of depository institutions and other 
financial intermediaries in the transfer of funds between parties. 

Our risk management systems may fall short of their intended objectives. 

We seek to monitor and control our risk exposure through a risk and control framework encompassing a variety of 

separate but complementary financial, credit, operational, compliance and legal reporting systems, internal controls, 
management review processes and other mechanisms.  Our risk management process seeks to balance our ability to profit 
from investing or lending positions with our exposure to potential losses.  While we employ a broad and diversified set of 
risk monitoring and risk mitigation techniques, those techniques and the judgments that accompany their application cannot 
anticipate every economic and financial outcome or the specifics and timing of such outcomes.  Thus, we may, in the 
course of our activities, incur losses. 

We may not be able to successfully adapt to evolving industry standards and market pressures. 

Our success depends, in part, on the ability to adapt products and services to evolving industry standards.  There is 

increasing pressure to provide products and services at lower prices.  This can reduce net interest income and noninterest 
income from fee-based products and services.  In addition, the widespread adoption of new technologies could require us to 
make substantial capital expenditures to modify or adapt existing products and services or develop new products and 
services.  We may not be successful in introducing new products and services in response to industry trends or 
developments in technology, or those new products may not achieve market acceptance.  As a result, we could lose 
business, be forced to price products and services on less advantageous terms to retain or attract clients, or be subject to 
cost increases.  As a result, our business, financial condition, or results of operations may be adversely affected. 

Our inability to integrate potential future acquisitions successfully could impede us from realizing all of the benefits 
of the acquisitions, which could weaken our operations. 

If we are unable to successfully integrate potential future acquisitions, we could be impeded from realizing all of 

the benefits of those acquisitions and could weaken our business operations.  The integration process may disrupt our 
business and, if implemented ineffectively, may preclude realization of the full benefits expected by us and could harm our 
results of operations. In addition, the overall integration of the combining companies may result in unanticipated problems, 
expenses, liabilities and competitive responses, and may cause our stock price to decline.  The difficulties of integrating an 
acquisition include, among others: 

° unanticipated issues in integration of information, communications and other systems; 
° unanticipated incompatibility of logistics, marketing and administration methods; 
° maintaining employee morale and retaining key employees; 
° integrating the business cultures of both companies; 
° preserving important strategic client relationships; 
° coordinating geographically diverse organizations; and 
° consolidating corporate and administrative infrastructures and eliminating duplicative operations. 

10 

 
 
 
  
 
  
  
  
  
  
  
  
Finally, even if the operations of an acquisition are integrated successfully, we may not realize the full benefits of 

the acquisition, including the synergies, cost savings or growth opportunities we expect.  These benefits may not be 
achieved within the anticipated time frame as well. 

The soundness of other financial institutions could adversely affect us.  

Our ability to engage in routine funding transactions could be adversely affected by the actions and commercial 

soundness of other financial institutions.  Financial services institutions are interrelated as a result of trading, clearing, 
counterparty or other relationships.  We have exposure to many different industries and counterparties, and we routinely 
execute transactions with counterparties in the financial industry.  As a result, defaults by, or even rumors or questions 
about, one or more financial services institutions, or the financial services industry generally, have led to market-wide 
liquidity problems and could lead to losses or defaults by us or by other institutions.  Even routine funding transactions 
expose us to credit risk in the event of default of our counterparty or client.  In addition, our credit risk may be exacerbated 
when the collateral held by us cannot be realized upon or is liquidated at prices not sufficient to recover the full amount of 
the financial instrument exposure due us.  There is no assurance that any such losses would not materially and adversely 
affect our results of operations.  

The timing and effect of Federal Reserve Board policy normalization remains uncertain. 

In September 2014, the Federal Reserve Board announced principles it would follow to implement monetary 

policy normalization, that is, to raise the Federal funds rate and other short-term interest rates to more historically normal 
levels and to reduce the Federal Reserve’s securities holdings, so as to promote its statutory mandate of maximum 
employment and price stability.  The Federal Open Market Committee (“FOMC”) took the initial step in that process by 
raising the Federal funds rate by 25 basis points in December 2015, the first such action since December 2008.  
Subsequently, the FOMC refined the normalization principles and announced greater detail about its planned approach.  In 
September 2017, the FOMC announced the start of gradual reduction in the Federal Reserve’s securities holdings, 
commencing in October 2017.  In each of March, June, and December 2017, the FOMC raised the Federal funds rate by 25 
basis points, and announced its intention to continue to raise the Federal funds rate gradually over the next few years.  
There can be no assurance that these reductions in the Federal Reserve’s securities holdings, and increases in the Federal 
funds rate, will continue to occur, that they will be gradual if they do occur, or as to the actual impact of those policies on 
the financial markets, the broader economy, or on our business, financial condition, results of operations, access to credit or 
the trading price of our common stock. 

The effect of financial services legislation and regulations remains uncertain. 

In response to the financial crisis, on July 21, 2010, President Obama signed the Dodd-Frank Act, the most 
comprehensive reform of the regulation of the financial services industry since the Great Depression of the 1930’s.  Among 
many other things, the Dodd-Frank Act provides for increased supervision of financial institutions by regulatory agencies, 
more stringent capital requirements for financial institutions, major changes to deposit insurance assessments by the FDIC, 
prohibitions on proprietary trading and sponsorship or investment in hedge funds and private equity funds by insured 
depository institutions, holding companies, and their affiliates, heightened regulation of hedging and derivatives activities, 
a greater focus on consumer protection issues, in part through the formation of a new Consumer Financial Protection 
Bureau (“CFPB”) having powers formerly split among different regulatory agencies, extensive changes to the regulation of 
residential mortgage lending, imposition of limits on interchange transaction and network fees for electronic debit 
transactions and repeal of the prohibition on payment of interest on demand deposits.  Many of the Dodd-Frank Act’s 
provisions have delayed effective dates, while other provisions require implementing regulations of various federal 
agencies, some of which have not yet been adopted in final form. 

On February 3, 2017, however, President Trump signed Executive Order 13772, specifying new core principles 

for regulating the U.S. financial system.  Among other things, the President directed the Secretary of the Treasury, in 
consultation with federal regulatory agencies, to review existing laws and regulations and report on the extent to which they 
were consistent with the core principles.  Beginning in February 2017, Congress passed, and the President signed, more 
than a dozen resolutions under the Congressional Review Act, repealing various federal regulations, including regulations 
adopted by the CFPB.  Certain bills pending in Congress would, if enacted, repeal or substantially amend various 
provisions of the Dodd-Frank Act.  Proposals to modify existing regulations in light of the new core principles are under 
consideration by various federal regulatory agencies, including the CFPB.  There can be no assurance that any such 
legislation will be enacted, or that changes in existing regulations will be adopted to implement the new core principles.

Thus, the effect of financial services legislation and regulations remains uncertain.  The implementation, amendment, or 
repeal of federal financial services laws or regulations may limit our business opportunities, impose additional costs on us, 
impact our revenues or the value of our assets, or otherwise adversely affect our business. 

Our credit losses could increase and our allowance may not be adequate to cover actual loan losses. 

The risk of nonpayment of loans is inherent in all lending activities, and nonpayment, when it occurs, may have a 

materially adverse effect on our earnings and overall financial condition as well as the value of our common stock.  Our 
focus on commercial lending may result in a larger concentration of loans to small businesses.  As a result, we may assume 
different or greater lending risks than other banks.  We make various assumptions and judgments about the collectability of 
our loan portfolio and provide an allowance for losses based on several factors.  If our assumptions are wrong, our 
allowance may not be sufficient to cover our losses, which would have an adverse effect on our operating results.  The 
actual amounts of future provisions for loan losses cannot be determined at this time and may exceed the amounts of past 
provisions. Additions to our allowance decrease our net income. 

We rely heavily on our management and other key personnel, and the loss of any of them may adversely affect our 
operations. 

We are and will continue to be dependent upon the services of our management team, including our executive 

officers and our other senior managers.  The unanticipated loss of our executive officers, or any of our other senior 
managers, could have an adverse effect on our growth and performance.  

 In addition, we continue to depend on our key commercial loan officers.  Several of our commercial loan officers 
are responsible, or share responsibility, for generating and managing a significant portion of our commercial loan portfolio.  
Our success can be attributed in large part to the relationships these officers as well as members of our management team 
have developed and are able to maintain with our customers as we continue to implement our community banking 
philosophy.  The loss of any of these commercial loan officers could adversely affect our loan portfolio and performance, 
and our ability to generate new loans.  Many of our key employees have signed agreements with us agreeing not to compete 
with us in one or more of our markets for specified time periods if they leave employment with us.  However, we may not 
be able to effectively enforce such agreements. 

Some of the other financial institutions in our markets also require their key employees to sign agreements that 

preclude or limit their ability to leave their employment and compete with them or solicit their customers.  These 
agreements make it more difficult for us to hire loan officers with experience in our markets who can immediately solicit 
their former or new customers on our behalf. 

Future sales of our common stock or other securities may dilute the value of our common stock. 

In many situations, our Board of Directors has the authority, without any vote of our shareholders, to issue shares 

of our authorized but unissued preferred or common stock, including shares authorized and unissued under our equity 
incentive plans.  In the future, we may issue additional securities, through public or private offerings, in order to raise 
additional capital.  Any such issuance would dilute the percentage of ownership interest of existing shareholders and may 
dilute the per share book value of the common stock.  In addition, option holders under our stock-based incentive plans 
may exercise their options at a time when we would otherwise be able to obtain additional equity capital on more favorable 
terms. 

We are subject to significant government regulation, and any regulatory changes may adversely affect us. 

The banking industry is heavily regulated under both federal and state law.  These regulations are primarily 

intended to protect customers, the federal deposit insurance fund, and the stability of the U.S. financial system, not our 
creditors or shareholders.  Existing state and federal banking laws subject us to substantial limitations with respect to the 
making of loans, the purchase of securities, the payment of dividends and many other aspects of our business.  Some of 
these laws may benefit us, others may increase our costs of doing business, or otherwise adversely affect us and create 
competitive advantages for others.  Regulations affecting banks and financial services companies undergo continuous 
change, which may be accelerated by the recent change in the federal administration, and we cannot predict the ultimate 
effect of these changes, which could have a material adverse effect on our profitability or financial condition.  Federal 
economic and monetary policy may also affect our ability to attract deposits, make loans and achieve satisfactory interest 
spreads.

Minimum capital requirements have increased. 

The provisions of the Dodd-Frank Act relating to capital to be maintained by financial institutions approach 

convergence with the standards (generally known as Basel III) adopted in December, 2010 by the Group of Governors and 
Heads of Supervision, the oversight body of the Basel Committee on Banking Supervision.  Among other things, those 
standards contain a narrower definition of elements qualifying for inclusion as Tier 1 capital and higher minimum risk-
based capital levels than those specified in previous U.S. law and regulations. In July, 2013, the U.S. federal bank 
regulatory agencies adopted regulations to implement the provisions of the Dodd-Frank Act and Basel III for U.S. financial 
institutions.  The new regulations became applicable to us and our bank effective January 1, 2015. 

The new regulations implemented (i) revised definitions of regulatory capital elements, (ii) a new common equity 

Tier 1 (“CET 1”) minimum capital ratio requirement, (iii) an increase in the existing minimum Tier 1 capital ratio 
requirement, (iv) new limits on capital distributions and certain discretionary bonus payments if an institution does not hold 
a specified amount of CET 1 (called a capital conservation buffer) in addition to the amount required to meet its minimum 
risk-based capital requirements, (v) new risk-weightings for certain categories of assets, and (vi) other requirements 
applicable to banking organizations which have total consolidated assets of $250 billion or more, total consolidated on-
balance sheet foreign exposure of $10 billion or more, elect to use the advanced measurement approach for calculating risk-
weighted assets, or are subsidiaries of banking organizations that use the advanced measurement approach (“Advanced 
Approaches Entities”). 

Among other things, the new regulations generally require banking organizations to recognize in regulatory capital 

most components of accumulated other comprehensive income (“AOCI”), including accumulated unrealized gains and losses 
on available for sale securities.  This requirement, which was not imposed under previous risk-based capital regulations, may 
be avoided by banking organizations, such as us and our bank, that are not Advanced Approaches Entities, by making a one-
time, irrevocable election on the first quarterly regulatory report following the date on which the regulations become 
effective as to them.  We made the one-time, irrevocable election regarding the treatment of AOCI on March 31, 2015. 

In addition, the new regulations (unlike the original proposal), permit companies such as us, which had total assets 

of less than $15 billion on December 31, 2009, and had issued trust preferred securities on or prior to May 19, 2010, to 
continue to include such securities in Tier 1 capital. 

On January 1, 2015, for banking organizations such as us and our bank that are not Advanced Approaches Entities, 

the new regulations mandated a minimum ratio of CET 1 to standardized total risk-weighted assets (“RWA”) of 4.5%, an 
increased ratio of Tier 1 capital to RWA of 6.0% (compared to the prior requirement of 4.0%), a total capital ratio (that is, 
the sum of Tier 1 and Tier 2 capital to RWA) of 8.0%, and a minimum leverage ratio (that is, Tier 1 capital to adjusted 
average total consolidated assets) of 4.0%.  The calculation of these amounts is affected by the new definitions of certain 
capital elements.  The capital conservation buffer comprised solely of CET 1 is being phased-in commencing January 1, 
2016, beginning at 0.625% of RWA and rising to 2.5% of RWA on January 1, 2019. Failure by a banking organization to 
maintain the aggregate required minimum capital ratios and capital conservation buffer will impair its ability to make 
certain distributions (including dividends and stock repurchases) and discretionary bonus payments to executive officers. 

These increased minimum capital requirements may adversely affect our ability (and that of our bank) to pay cash 
dividends, reduce our profitability, or otherwise adversely affect our business, financial condition or results of operations.  
In the event of a need for additional capital to meet these requirements, there can be no assurance of our ability to raise 
funding in the equity and capital markets.  Factors that we cannot control, such as the disruption of financial markets or 
negative views of the financial services industry generally, could impair our ability to raise qualifying equity capital.  In 
addition, our ability to raise qualifying equity capital could be impaired if investors develop a negative perception of our 
financial prospects.  If we were unable to raise qualifying equity capital, it might be necessary for us to sell assets in order 
to maintain required capital ratios.  We may be unable to sell some of our assets, or we may have to sell assets at a discount 
from market value, either of which could adversely affect our results of operations, cash flow and financial condition.

We may need to raise additional capital in the future, and such capital may not be available when needed or at all. 

We may need or want to raise additional capital in the future to provide us with sufficient capital resources and 

liquidity to meet our commitments and business needs, particularly if our asset quality or earnings were to deteriorate 
significantly.  Our ability to raise additional capital will depend on, among other things, conditions in the capital markets at 
that time, which are outside of our control, and our financial performance.  Economic conditions and any loss of confidence 
in financial institutions generally may increase our cost of funding and limit access to certain customary sources of capital. 

There can be no assurance that capital will be available on acceptable terms or at all. Any occurrence that may 
limit our access to the capital markets, such as a decline in the confidence of equity or debt purchasers, or counterparties 
participating in the capital markets, may adversely affect our capital costs and our ability to raise capital and, potentially, 
our liquidity.  Also, if we need to raise capital in the future, we may have to do so when many other financial institutions 
are also seeking to raise capital and would have to compete with those institutions for investors.  An inability to raise 
additional capital on acceptable terms when needed could have a materially adverse effect on our business, financial 
condition and results of operations. 

Changes in the method of determining Libor, or the replacement of Libor with an alternative reference rate, may 
adversely affect interest income or expense. 

Many of the commercial loans we make bear interest at a floating rate based on Libor, the London inter-bank 

offered rate.  We pay interest on certain subordinated notes related to our trust preferred securities, and a related interest 
rate swap agreement, at rates based on Libor 

On July 27, 2017, the United Kingdom Financial Conduct Authority, which oversees Libor, formally announced 

that it could not assure the continued existence of Libor in its current form beyond the end of 2021, and that an orderly 
transition process to one or more alternative benchmarks should begin.  In June 2017, the Alternative Reference Rates 
Committee, a steering committee comprised of large U.S. financial institutions organized by the Federal Reserve, 
announced that it had selected a modified version of the unpublished Broad Treasuries Financing Rate as the preferred 
alternative reference rate for U.S. dollar obligations.  That rate, now referred to as the Secured Overnight Funding Rate 
(“SOFR”), is determined based upon actual transactions in certain portions of the bi-lateral and tri-party overnight 
repurchase agreement markets for certain U.S. Treasury obligations.  The Federal Reserve Bank of New York has stated 
that it expected to begin publication of the SOFR in the first half of 2018. 

In February 2018, an international consortium of market participant trade associations published the IBOR Global 
Benchmark Survey 2018 Transition Roadmap (“Roadmap”).  The Roadmap summarizes the background to the use of inter-
bank offered rate benchmarks, discusses perceived reasons for reform, and identifies problems that may be encountered in 
making a transition to new interest rate benchmarks.  Those potential problems include market adoption, liquidity, legal, 
valuation and risk management, infrastructure, tax, accounting, governance and control, and regulatory issues. 

It is unclear whether, or in what form, Libor will continue to exist after 2021.  Any transition to an alternative 

benchmark will require careful consideration and implementation so as not to disrupt the stability of financial markets.  If 
Libor ceases to exist, we may need to take a variety of actions, including negotiating certain of our agreements based on an 
alternative benchmark that may be established, if any.  There is no guarantee that a transition from Libor to an alternative 
benchmark will not result in financial market disruptions, significant changes in benchmark rates, or adverse changes in the 
value of certain of our loans, and our income and expense. 

We continually encounter technological change, and we may have fewer resources than our competitors to continue 
to invest in technological improvements. 

The banking industry is undergoing technological changes with frequent introductions of new technology-driven 

products and services.  In addition to better serving customers, the effective use of technology increases efficiency and 
enables financial institutions to reduce costs.  Our future success will depend, in part, on our ability to address the needs of 
our customers by using technology to provide products and services that will satisfy customer demands for convenience as 
well as create additional efficiencies in our operations.  Many of our competitors have substantially greater resources to 
invest in technological improvements than we do.  There can be no assurance that we will be able to effectively implement 
new technology-driven products and services or be successful in marketing these products and services to our customers.

Our Articles of Incorporation and By-laws and the laws of the State of Michigan contain provisions that may 
discourage or prevent a takeover of our company and reduce any takeover premium. 

Our Articles of Incorporation and By-laws, and the corporate laws of the State of Michigan, include provisions 
which are designed to provide our Board of Directors with time to consider whether a hostile takeover offer is in our and 
our shareholders’ best interest.  These provisions, however, could discourage potential acquisition proposals and could 
delay or prevent a change in control.  The provisions also could diminish the opportunities for a holder of our common 
stock to participate in tender offers, including tender offers at a price above the then-current market price for our common 
stock.  These provisions could also prevent transactions in which our shareholders might otherwise receive a premium for 
their shares over then-current market prices, and may limit the ability of our shareholders to approve transactions that they 
may deem to be in their best interest. 

The Michigan Business Corporation Act contains provisions intended to protect shareholders and prohibit or 

discourage various types of hostile takeover activities. In addition to these provisions and the provisions of our Articles of 
Incorporation and By-laws, federal law requires the Federal Reserve Board’s approval prior to acquiring “control” of a 
bank holding company.  All of these provisions may delay or prevent a change in control without action by our 
shareholders and could adversely affect the price of our common stock. 

There is a limited trading market for our common stock. 

The price of our common stock has been, and will likely continue to be, subject to fluctuations based on, among 

other things, economic and market conditions for bank holding companies and the stock market in general, as well as 
changes in investor perceptions of our company.  The issuance of new shares of our common stock also may affect the 
market for our common stock. 

Our common stock is traded on the Nasdaq Global Select Market under the symbol “MBWM.”  The development 
and maintenance of an active public trading market depends upon the existence of willing buyers and sellers, the presence 
of which is beyond our control.  While we are a publicly-traded company, the volume of trading activity in our stock is still 
relatively limited.  Even if a more active market develops, there can be no assurance that such a market will continue, or 
that our shareholders will be able to sell their shares at or above the price at which they acquired shares. 

Our business is subject to operational risks. 

We, like most financial institutions, are exposed to many types of operational risks, including the risk of fraud by 

employees or outsiders, unauthorized transactions by employees or operational errors.  Operational errors may include 
clerical or record keeping errors or those resulting from faulty or disabled computer or telecommunications systems.  Given 
our volume of transactions, certain errors may be repeated or compounded before they are discovered and successfully 
corrected.  Our necessary dependence upon automated systems to record and process our transaction volume may further 
increase the risk that technical system flaws or employee tampering or manipulation of those systems will result in losses 
that are difficult to detect.  

We may also be subject to disruptions of our operating systems arising from events that are wholly or partially 

beyond our control, including, for example, computer viruses or electrical or telecommunications outages, which may give 
rise to losses in service to customers and to loss or liability to us.  We are further exposed to the risk that our external 
vendors may be unable to fulfill their contractual obligations to us, or will be subject to the same risk of fraud or 
operational errors by their respective employees as are we, and to the risk that our or our vendors’ business continuity and 
data security systems prove not to be adequate.  We also face the risk that the design of our controls and procedures proves 
inadequate or is circumvented, causing delays in detection or errors in information.  Although we maintain a system of 
controls designed to keep operational risks at appropriate levels, there can be no assurance that we will not suffer losses 
from operational risks in the future that may be material in amount.

We face the risk of cyber-attack to our computer systems. 

In the ordinary course of business, we collect and store sensitive data, including proprietary business information 

and personally identifiable information of our customers and employees in systems and on networks.  The secure 
processing, maintenance and use of this information is critical to our operations.  To date, we have not experienced a 
significant compromise, significant data loss or any material financial losses related to cybersecurity attacks, but our 
systems and those of our customers and third-party service providers are under constant threat, and it is possible that we 
could experience a significant event in the future.  Cybersecurity threats include unauthorized access, loss or destruction of 
data (including confidential client information), account takeovers, unavailability of service, computer viruses or other 
malicious code, cyber-attacks and other events.  These threats may derive from human error, fraud or malice on the part of 
employees or third parties, or may result from accidental technological failure.  If one or more of these events occurs, it 
could result in the disclosure of confidential client information, damage to our reputation with our clients and the market, 
additional costs to us (such as repairing systems or adding new personnel or protection technologies), regulatory penalties 
and financial losses, to both us and our clients and customers.  Such events could also cause interruptions or malfunctions 
in our operations (such as the lack of availability of our online banking system), as well as the operations of our clients, 
customers or other third parties.  Risks and exposures related to cybersecurity attacks are expected to remain high for the 
foreseeable future due to the rapidly evolving nature and sophistication of these threats, as well as due to the expanding use 
of Internet banking, mobile banking and other technology-based products and services by us and our customers. 
Although we maintain safeguards to protect against these risks, there can be no assurance that we will not suffer losses in 
the future that may be material in amount. 

In March 2015, federal regulators issued two related statements regarding cybersecurity.  One statement indicates 
that financial institutions should design multiple layers of security controls to establish lines of defense and to ensure that 
their risk management processes also address the risk posed by compromised customer credentials, including security 
measures to reliably authenticate customers accessing internet-based services of the financial institution.  The other 
statement indicates that a financial institution’s management is expected to maintain sufficient business continuity planning 
processes to ensure the rapid recovery, resumption and maintenance of the institution’s operations after a cyber-attack 
involving destructive malware.  A financial institution is also expected to develop appropriate processes to enable recovery 
of data and business operations and address rebuilding network capabilities and restoring data if the institution or its critical 
service providers fall victim to this type of cyber-attack.  If we fail to observe the regulatory guidance, we could be subject 
to various regulatory sanctions, including financial penalties. 

Damage to our reputation could materially harm our business. 

Our relationship with many of our clients is predicated upon our reputation as a fiduciary and a service provider 
that adheres to the highest standards of ethics, service quality and regulatory compliance.  Adverse publicity, regulatory 
actions, litigation, operational failures, the failure to meet client expectations and other issues with respect to one or more 
of our businesses could materially and adversely affect our reputation, our ability to attract and retain clients or our sources 
of funding for the same or other businesses.  Preserving and enhancing our reputation also depends on maintaining systems 
and procedures that address known risks and regulatory requirements, as well as our ability to identify and mitigate 
additional risks that arise due to changes in our businesses and the marketplaces in which we operate, the regulatory 
environment and client expectations. If any of these developments has a material effect on our reputation, our business will 
suffer.      

Item 1B.  Unresolved Staff Comments 

We have received no written comments regarding our periodic or current reports from the staff of the Securities 

and Exchange Commission that were issued 180 days or more before the end of our 2017 fiscal year and that remain 
unresolved.

Item 2.  Properties. 

Our headquarters is located in our bank’s main office facility in Grand Rapids, Michigan.  Our bank operates 49 

banking offices primarily concentrated throughout Western and Central Michigan, most of which are full-service facilities.  
We also opened a banking office in Troy, Michigan during the first quarter of 2017.  We have larger banking facilities in 
Alma, Holland, Ionia, Kalamazoo, Lansing, Mt. Pleasant and West Branch.  The remaining banking offices generally range 
in size from 1,200 to 3,200 square feet, based on the location and number of employees located at the facility.  Forty-three 
of the banking offices are owned by our bank, and six are rented under various operating lease agreements.  In several 
instances, the banking offices contain more usable space than what is needed for current banking operations.  This excess 
space, totaling approximately 23,500 square feet, is generally leased to unrelated businesses. In addition, certain functions 
operate out of our standalone facility located in Alma. 

We consider our properties and equipment to be well maintained, in good operating condition and capable of 
accommodating current growth forecasts.  However, we may choose to add branch locations to expand our presence in 
current markets and/or in new markets or, alternatively, to consolidate, close or relocate branches if we believe it would be 
beneficial to our overall performance. 

Item 3.  Legal Proceedings. 

From time to time, we may be involved in various legal proceedings that are incidental to our business.  In the 

opinion of management, we are not a party to any legal proceedings that are material to our financial condition, either 
individually or in the aggregate. 

Item 4.  Mine Safety Disclosures. 

Not applicable. 

PART II 

Item 5.  Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity 

Securities. 

Our common stock is traded on the Nasdaq Global Select Market under the symbol “MBWM.”  At March 1, 2018, 

there were approximately 1,600 record holders of our common stock. In addition, we estimate that there were 
approximately 7,000 beneficial owners of our common stock who own their shares through brokers or banks. 

The following table shows the high and low sales prices for our common stock as reported by the Nasdaq Global 

Select Market for the periods indicated and the quarterly and special cash dividends paid by us during those periods.

Holders of our common stock are entitled to receive dividends that the Board of Directors may declare from time 

to time.  We may only pay dividends out of funds that are legally available for that purpose.  We are a financial holding 
company and substantially all of our assets are held by our bank and its subsidiaries.  Our ability to pay dividends to our 
shareholders depends primarily on our bank’s ability to pay dividends to us.  Dividend payments and extensions of credit to 
us from our bank are subject to legal and regulatory limitations, generally based on capital levels and current and retained 
earnings, imposed by law and regulatory agencies with authority over our bank.  The ability of our bank to pay dividends is 
also subject to its profitability, financial condition, capital expenditures and other cash flow requirements.  In addition, 
under the terms of our subordinated debentures, we would be precluded from paying dividends on our common stock if an 
event of default has occurred and is continuing under the subordinated debentures, or if we exercised our right to defer 
payments of interest on the subordinated debentures, until the deferral ended. 

We and our bank are subject to regulatory capital requirements administered by state and federal banking 

agencies.  Failure to meet the various capital requirements can initiate regulatory action that could have a direct material 
effect on our financial statements.  Our bank’s ability to pay cash and stock dividends is subject to limitations under various 
laws and regulations and to prudent and sound banking practices. 

On January 12, 2017, our Board of Directors declared a cash dividend on our common stock in the amount of 

$0.18 per share that was paid on March 22, 2017 to shareholders of record as of March 10, 2017.  On April 13, 2017, our 
Board of Directors declared a cash dividend on our common stock in the amount of $0.18 per share that was paid on June 
21, 2017 to shareholders of record as of June 9, 2017.  On July 13, 2017, our Board of Directors declared a cash dividend 
on our common stock in the amount of $0.19 per share that was paid on September 20, 2017 to shareholders of record as of 
September 8, 2017.  On October 12, 2017, our Board of Directors declared a cash dividend on our common stock in the 
amount of $0.19 per share that was paid on December 20, 2017 to shareholders of record as of December 8, 2017. 

On January 14, 2016, our Board of Directors declared a cash dividend on our common stock in the amount of 

$0.16 per share that was paid on March 23, 2016 to shareholders of record as of March 11, 2016.  On April 14, 2016, our 
Board of Directors declared a cash dividend on our common stock in the amount of $0.16 per share that was paid on June

per share that was paid on September 21, 2016 to shareholders of record as of September 9, 2016.  On October 13, 2016, 
our Board of Directors declared a cash dividend on our common stock in the amount of $0.17 per share that was paid on 
December 21, 2016 to shareholders of record as of December 9, 2016.  In addition, on October 13, 2016, our Board of

Item 9A.  Controls and Procedures. 

As of December 31, 2017, an evaluation was performed under the supervision of and with the participation of our 

management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and 
operation of our disclosure controls and procedures.  Based on that evaluation, our management, including our Chief 
Executive Officer and Chief Financial Officer, concluded that our disclosure controls and procedures were effective as of 
December 31, 2017.  

There have been no significant changes in our internal control over financial reporting during the quarter ended 
December 31, 2017, that have materially affected, or are reasonably likely to materially affect, our internal control over 
financial reporting. 

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, 

as such term is defined in Exchange Act Rules 13a-15(f).  There are inherent limitations in the effectiveness of any system 
of internal control. Accordingly, even an effective system of internal control can provide only reasonable assurance with 
respect to financial statement preparation. 

Under the supervision and with the participation of our management, including our Chief Executive Officer and 
Chief Financial Officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting as 
of December 31, 2017.  This evaluation was based on criteria for effective internal control over financial reporting 
described in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the 
Treadway Commission (“COSO”).  Based on our evaluation under the COSO framework, our management concluded that 
our internal control over financial reporting was effective as of December 31, 2017.  Refer to page F-33 for management’s 
report. 

Our independent registered public accounting firm has issued an audit report on our internal control over financial 

reporting which is included in this Annual Report.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF 
OPERATIONS 

FORWARD-LOOKING STATEMENTS 

The following discussion and other portions of this Annual Report contain forward-looking statements that are based on 
management’s beliefs, assumptions, current expectations, estimates and projections about the financial services industry, 
the economy, and about our company.  Words such as “anticipates,” “believes,” “estimates,” “expects,” “forecasts,” 
“intends,” “is likely,” “plans,” “projects,” and variations of such words and similar expressions are intended to identify 
such forward-looking statements.  These statements are not guarantees of future performance and involve certain risks, 
uncertainties and assumptions (“Future Factors”) that are difficult to predict with regard to timing, extent, likelihood and 
degree of occurrence.  Therefore, actual results and outcomes may materially differ from what may be expressed or 
forecasted in such forward-looking statements.  We undertake no obligation to update, amend, or clarify forward-looking 
statements, whether as a result of new information, future events (whether anticipated or unanticipated), or otherwise. 

Future Factors include, among others, changes in interest rates and interest rate relationships; demand for products and 
services; the degree of competition by traditional and non-traditional competitors; changes in banking regulation or actions 
by bank regulators; changes in tax laws; changes in prices, levies, and assessments; impact of technological advances; 
governmental and regulatory policy changes; outcomes of contingencies; trends in customer behavior as well as their 
ability to repay loans; changes in local real estate values; changes in the national and local economies; and other risk factors 
described in Item 1A of this Annual Report.  These are representative of the Future Factors that could cause a difference 
between an ultimate actual outcome and a forward-looking statement. 

CRITICAL ACCOUNTING POLICIES AND ESTIMATES 

Management’s Discussion and Analysis of Financial Condition and Results of Operations (“Management’s Discussion and 
Analysis”) is based on Mercantile Bank Corporation’s consolidated financial statements, which have been prepared in 
accordance with accounting principles generally accepted in the United States of America.  The preparation of these 
financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, 
revenues and expenses.  Material estimates that are particularly susceptible to significant change in the near term relate to 
the determination of the allowance for loan losses, and actual results could differ from those estimates.  We have reviewed 
the analyses with the Audit Committee of our Board of Directors. 

Allowance For Loan Losses: The allowance for loan losses (“allowance”) is maintained at a level we believe is adequate to 
absorb probable incurred losses identified and inherent in the loan portfolio.  Our evaluation of the adequacy of the 
allowance is an estimate based on past loan loss experience, the nature and volume of the loan portfolio, information about 
specific borrower situations and estimated collateral values, guidance from bank regulatory agencies, and assessments of 
the impact of current and anticipated economic conditions on the loan portfolio.  Allocations of the allowance may be made 
for specific loans, but the entire allowance is available for any loan that, in our judgment, should be charged-off. Loan 
losses are charged against the allowance when we believe the uncollectability of a loan is likely.  The balance of the 
allowance represents our best estimate, but significant downturns in circumstances relating to loan quality or economic 
conditions could result in a requirement for an increased allowance in the future. Likewise, an upturn in loan quality or 
improved economic conditions may result in a decline in the required allowance in the future.  In either instance, 
unanticipated changes could have a significant impact on the allowance and operating results. 

We complete a migration analysis quarterly to assist us in determining appropriate reserve allocation factors for non-
impaired loans.  Our migration takes into account various time periods; however, at year-end 2017 we placed most weight 
on the period starting December 31, 2010 through December 31, 2017.  We believe this period represents an appropriate 
range of economic conditions, and that it provides for an appropriate basis in determining reserve allocation factors given 
current economic conditions and the general market consensus of economic conditions in the near future.  

F-4 

 
  
 
  
  
  
   
  
  
  
  
  
 
 
 
 
 
Although the migration analysis provides an accurate historical accounting of our net loan losses, it is not able to fully 
account for environmental factors that will also very likely impact the collectability of our loans as of any quarter-end date.  
Therefore, we incorporate the environmental factors as adjustments to the historical data. Environmental factors include 
both internal and external items.  We believe the most significant internal environmental factor is our credit culture and the 
relative aggressiveness in assigning and revising commercial loan risk ratings, with the most significant external 
environmental factor being the assessment of the current economic environment and the resulting implications on our loan 
portfolio. 

The allowance is increased through a provision charged to operating expense.  Uncollectable loans are charged-off through 
the allowance. Recoveries of loans previously charged-off are added to the allowance.  A loan is considered impaired when 
it is probable that contractual principal and interest payments will not be collected either for the amounts or by the dates as 
scheduled in the loan agreement.  Impairment is evaluated in aggregate for smaller-balance loans of similar nature such as 
residential mortgage, consumer and credit card loans, and on an individual loan basis for other loans.  If a loan is impaired, 
a portion of the allowance is allocated so that the loan is reported, net, at the present value of estimated future cash flows 
using the loan’s existing interest rate or at the fair value of collateral if repayment is expected solely from the collateral.  
The timing of obtaining outside appraisals varies, generally depending on the nature and complexity of the property being 
evaluated, general breadth of activity within the marketplace and the age of the most recent appraisal.  For collateral 
dependent impaired loans, in most cases we obtain and use the “as is” value as indicated in the appraisal report, adjusting 
for any expected selling costs.  In certain circumstances, we may internally update outside appraisals based on recent 
information impacting a particular or similar property, or due to identifiable trends (e.g., recent sales of similar properties) 
within our markets.  The expected future cash flows exclude potential cash flows from certain guarantors. To the extent 
these guarantors are able to provide repayments, a recovery would be recorded upon receipt.  Loans are evaluated for 
impairment when payments are delayed, typically 30 days or more, or when serious deficiencies are identified within the 
credit relationship.  Our policy for recognizing income on impaired loans is to accrue interest unless a loan is placed on 
nonaccrual status.  We put loans into nonaccrual status when the full collection of principal and interest is not expected. 

Income Tax Accounting: Current income tax assets and liabilities are established for the amount of taxes payable or 
refundable for the current year. In the preparation of income tax returns, tax positions are taken based on interpretation of 
federal and state income tax laws for which the outcome may be uncertain.  We periodically review and evaluate the status 
of our tax positions and make adjustments as necessary.  Deferred income tax assets and liabilities are also established for 
the future tax consequences of events that have been recognized in our financial statements or tax returns.  A deferred 
income tax asset or liability is recognized for the estimated future tax effects attributable to temporary differences that can 
be carried forward (used) in future years.  The valuation of our net deferred income tax asset is considered critical as it 
requires us to make estimates based on provisions of the enacted tax laws.  The assessment of the realizability of the net 
deferred income tax asset involves the use of estimates, assumptions, interpretations and judgments concerning accounting 
pronouncements, federal and state tax codes and the extent of future taxable income.  There can be no assurance that future 
events, such as court decisions, positions of federal and state taxing authorities, and the extent of future taxable income will 
not differ from our current assessment, the impact of which could be significant to the consolidated results of operations 
and reported earnings.  

Accounting guidance requires us to assess whether a valuation allowance should be established against our deferred tax 
assets based on the consideration of all available evidence using a “more likely than not” standard. In making such 
judgments, we consider both positive and negative evidence and analyze changes in near-term market conditions as well as 
other factors that may impact future operating results.  Significant weight is given to evidence that can be objectively 
verified.

Securities and Other Financial Instruments: Securities available for sale consist of bonds and notes which might be sold 
prior to maturity due to changes in interest rates, prepayment risks, yield and availability of alternative investments, 
liquidity needs and other factors. Securities classified as available for sale are reported at their fair value.  Declines in the 
fair value of securities below their cost that are other than temporary are reflected as realized losses.  In estimating other 
than temporary losses, we consider: (1) the length of time and extent that fair value has been less than carrying value; (2) 
the financial condition and near term prospects of the issuer; and (3) our ability and intent to hold the security for a period 
of time sufficient to allow for any anticipated recovery in fair value.  Fair values for securities available for sale are 
generally obtained from outside sources and applied to individual securities within the portfolio.  The difference between 
the amortized cost and the current fair value of securities is recorded as a valuation adjustment and reported in other 
comprehensive income. 

Mortgage Servicing Rights: Mortgage servicing rights are recognized as assets based on the allocated fair value of retained 
servicing rights on mortgage loans sold. Servicing rights are carried at the lower of amortized cost or fair value and are 
expensed in proportion to, and over the period of, estimated net servicing income.  We utilize a discounted cash flow model 
to determine the value of our servicing rights.  The valuation model utilizes mortgage loan prepayment speeds, the 
remaining life of the mortgage loan pool, delinquency rates, our cost to service the mortgage loans and other factors to 
determine the cash flow that we will receive from servicing each grouping of mortgage loans.  These cash flows are then 
discounted based on current interest rate assumptions to arrive at the fair value of the right to service those mortgage loans.  
Impairment is evaluated quarterly based on the fair value of the mortgage servicing rights, using groupings of the 
underlying mortgage loans classified by interest rates.  Any impairment of a grouping is reported as a valuation allowance. 

Goodwill: Generally accepted accounting principles require us to determine the fair value of all of the assets and liabilities 
of an acquired entity, and record their fair value on the date of acquisition.  We employ a variety of means in determination 
of the fair value, including the use of discounted cash flow analysis, market comparisons and projected revenue streams.  
For certain items that we believe we have the appropriate expertise to determine the fair value, we may choose to use our 
own calculation of the value. In other cases, where the value is not easily determined, we consult with outside parties to 
determine the fair value of the asset or liability.  Once valuations have been adjusted, the net difference between the price 
paid for the acquired company and the fair value of its balance sheet is recorded as goodwill. 

Goodwill is assessed at least annually for impairment and any such impairment is recognized in the period identified.  A 
more frequent assessment is performed should events or changes in circumstances indicate the carrying value of the 
goodwill may not be recoverable.  We may elect to perform a qualitative assessment for the annual impairment test.  If the 
qualitative assessment indicates it is more likely than not that the fair value of a reporting unit is less than its carrying 
amount, or if we elect not to perform a qualitative assessment, then we would be required to perform a quantitative test for 
goodwill impairment.  The quantitative test is a two-step process consisting of comparing the carrying value of the 
reporting unit to an estimate of its fair value. If the estimated fair value of the reporting unit is less than the carrying value, 
goodwill is impaired and is written down to its estimated fair value.  In 2016 and 2017, we elected to perform a qualitative 
assessment for our annual impairment test and concluded it is more likely than not our fair value was greater than its 
carrying amount; therefore, no further testing was required.  Our qualitative assessment considered factors such as 
macroeconomic conditions, market conditions specifically related to the banking industry and our overall financial 
condition and results of operations.

FINANCIAL OVERVIEW 

We recorded net income of $31.3 million, or $1.90 per diluted share, for 2017.  For 2016, we recorded net income of $31.9 
million, or $1.96 per diluted share.  Excluding the impacts of certain one-time transactions, diluted earnings per share 
during 2017 and 2016 equaled $1.89 and $1.76, respectively.  These transactions included a bank owned life insurance 
death benefit claim during the first quarter of 2017, the revaluation of our net deferred tax asset in response to the Tax Cuts 
and Jobs Act becoming law in late 2017, the repurchase of trust preferred securities at a large discount during the first 
quarter of 2016, and accelerated purchase discount accretion on called U.S. Government agency bonds during 2016. 

The overall quality of our loan portfolio remains strong, with nonperforming loans equaling only 0.28% of total loans as of 
December 31, 2017.  Gross loan charge-offs during 2017 totaled $3.2 million, while recoveries of prior period loan charge-
offs totaled $1.8 million, providing for net loan charge-offs of $1.4 million, or only 0.06% of average total loans.  We 
continue our collection efforts on charged-off loans, and expect to record recoveries in future periods; however, given the 
nature of these efforts, it is not practical to forecast the dollar amount and timing of the recoveries. Accruing loans past due 
30 to 89 days remain very low. 

New commercial term loan originations totaled approximately $529 million in 2017, similar to the $549 million and $532 
million we booked during 2016 and 2015, respectively.  We also experienced net increases in commercial lines of credit 
during the past three years, in large part reflecting lines that are part of new commercial lending relationships established 
during recent quarterly periods.  Net loan growth equaled $180 million during 2017, compared to $101 million and $188 
million during 2016 and 2015, respectively, with all years reflecting the impact of scheduled monthly payments as well as 
expected and unexpected commercial loan payoffs.  During 2017, total commercial loans grew $138 million, or 6.7%, 
reflecting growth in the commercial and industrial, commercial real estate owner occupied and commercial real estate non-
owner occupied segments.  The new loan pipeline remains strong, and at year-end 2017, we had $154 million in unfunded 
loan commitments on commercial construction and development projects that are in the construction phase.  We believe 
our loan portfolio is well diversified, with commercial real estate non-owner occupied loans comprising 31%, commercial 
and industrial loans equaling 29%, commercial real estate owner occupied loans comprising 21% and residential mortgage 
and consumer loans aggregating 14% of total loans as of December 31, 2017.  As a percent of total commercial loans, 
commercial and industrial loans and commercial real estate owner occupied loans combined equaled 58% at year-end 2017, 
compared to 56% at December 31, 2016. 

Our funding structure is also well diversified.  As of December 31, 2017, noninterest-bearing checking accounts comprised 
31% of total funds, interest-bearing checking and securities sold under agreements to repurchase (“sweep accounts”) 
combined for 18%, savings and money market deposit accounts aggregated to 26% and local time deposits accounted for 
14%.  Wholesale funds, comprised of brokered deposits and Federal Home Loan Bank of Indianapolis (“FHLBI”) 
advances, represented 11% of total funds. 

FINANCIAL CONDITION 

Our total assets increased $204 million during 2017, and totaled $3.29 billion as of December 31, 2017.  Total loans 
increased $180 million, securities available for sale were up $7.7 million and interest-earning deposits grew $11.6 million.  
Total deposits increased $147 million and FHLBI advances were up $45.0 million, while sweep accounts were down $13.0 
million during 2017. 

Earning Assets 
Average earning assets equaled 92.8% of average total assets during 2017, similar to the 92.5% during 2016.  The loan 
portfolio continued to comprise a majority and increasing level of earning assets, followed by securities and interest-
earning deposits.  Average total loans equaled 85.2% of average earning assets during 2017, compared to 84.9% in 2016, 
while securities and other interest-earning assets combined comprised 14.8% of average earning assets during 2017, 
compared to 15.1% in 2016.  We anticipate the level of earning assets to total assets remaining relatively stable at 
approximately 93%.

Our loan portfolio has historically been primarily comprised of commercial loans.  Commercial loans increased $138 
million during 2017, and at December 31, 2017 totaled $2.20 billion, or 86.1% of the loan portfolio.  As of December 31, 
2016, the commercial loan portfolio comprised 86.8% of total loans.  Owner occupied commercial real estate (“CRE”) 
loans increased $75.9 million, commercial and industrial loans were up $39.9 million and non-owner occupied CRE loans 
increased $43.4 million, while multi-family and residential rental loans declined $16.0 million and vacant land, land 
development and residential construction loans were down $5.0 million.  As a percent of total commercial loans, 
commercial and industrial loans and owner occupied CRE loans combined equaled 58.1% as of December 31, 2017, 
compared to 56.4% as of December 31, 2016. 

We have significantly enhanced our commercial loan calling efforts over the past several years.  We are very pleased with 
the $1.61 billion in new commercial term loan fundings over the past three years, and our current commercial loan pipeline 
reports indicate continued strong commercial loan funding opportunities in future periods.  Also, as of December 31, 2017, 
availability on existing construction and development loans totaled $154 million, with most of those commitments expected 
to be drawn during 2018.  Further, we have made additional lending commitments totaling $185 million, a majority of 
which we expect to be accepted and funded over the next 12 to 18 months.  Our commercial loan officers also report 
significant additional opportunities they are currently discussing with existing borrowers and potential new customers. 

We continue to experience commercial loan principal paydowns and payoffs.  While a portion of the principal paydowns 
and payoffs received thus far have been welcomed, such as on stressed lending relationships, we have also experienced 
significant instances where well-performing relationships have been refinanced at other financial institutions or non-bank 
companies, and other situations where the borrower has sold the underlying asset.  In many of those cases where the loans 
have been refinanced elsewhere, we believed the terms and conditions of the new lending arrangements were too 
aggressive, generally reflecting the very competitive banking environment in our markets.  We remain committed to 
prudent underwriting standards that provide for an appropriate yield and risk relationship, as well as concentration limits 
we have established within our commercial loan portfolio.  In addition, we continue to receive accelerated principal 
paydowns from certain borrowers who have elevated deposit balances generally resulting from profitable operations and an 
apparent unwillingness to expand their business and/or replace equipment due to economic- and tax-related uncertainties.  
Usage of existing commercial lines of credit has remained relatively steady. 

Residential mortgage loans increased $59.3 million during 2017, totaling $255 million or 10.0% of total loans, at December 
31, 2017.  We originated $223 million in residential mortgage loans during 2017, an almost 37% increase from the volume 
originated in 2016, in large part reflecting our enhanced residential mortgage banking operation over the past couple of 
years.  We sold $108 million of the residential mortgage loans originated in 2017, or about 48%, generally comprised of 
longer-term fixed rate mortgage loans.  The remaining $115 million was added to our balance sheet, in large part comprised 
of adjustable rate residential mortgage loans.  We are pleased with the success of our strategic initiative to grow our 
residential mortgage banking operation, and expect origination volume to increase in future periods.  We expect to sell 50% 
to 55% of the new residential mortgage loan originations in 2018, with a vast majority of the loans added to our balance 
sheet to be comprised of adjustable rate mortgage loans.  Other consumer-related loans declined $17.6 million during 2017, 
and at December 31, 2017 totaled $100 million, or 3.9% of the loan portfolio.  Other consumer-related loans equaled 5.0% 
of total loans as of December 31, 2016.  We expect this loan portfolio segment to decline in future periods as scheduled 
principal payments exceed origination volumes.

Our credit policies establish guidelines to manage credit risk and asset quality.  These guidelines include loan review and 
early identification of problem loans to provide effective loan portfolio administration.  The credit policies and procedures 
are meant to minimize the risk and uncertainties inherent in lending. In following these policies and procedures, we must 
rely on estimates, appraisals and evaluations of loans and the possibility that changes in these could occur quickly because 
of changing economic conditions.  Identified problem loans, which exhibit characteristics (financial or otherwise) that 
could cause the loans to become nonperforming or require restructuring in the future, are included on the internal loan 
watch list.  Senior management and the Board of Directors review this list regularly.  Market value estimates of collateral 
on impaired loans, as well as on foreclosed and repossessed assets, are reviewed periodically; however, we have a process 
in place to monitor whether value estimates at each quarter-end are reflective of current market conditions.  Our credit 
policies establish criteria for obtaining appraisals and determining internal value estimates.  We may also adjust outside and 
internal valuations based on identifiable trends within our markets, such as recent sales of similar properties or assets, 
listing prices and offers received. In addition, we may discount certain appraised and internal value estimates to address 
distressed market conditions.

Nonperforming assets, comprised of nonaccrual loans, loans past due 90 days or more and accruing interest and foreclosed 
properties, totaled $9.4 million (0.3% of total assets) as of December 31, 2017, compared to $6.4 million (0.2% of total 
assets) as of December 31, 2016.  The volume of nonperforming assets has generally been on a steady trend over the past 
several years.  One commercial loan relationship, which was placed on nonaccrual during late 2014, accounted for 
approximately 70% of total nonperforming assets at year-end 2014.  This relationship was resolved during mid-2015.  
Given the low level of nonperforming loans and accruing loans 30 to 89 days delinquent, combined with a steady level of 
watch list credits and what we believe are strong credit administration practices, we are pleased with the overall quality of 
the loan portfolio. 

The following tables provide a breakdown of nonperforming assets by property type:

Gross loan charge-offs equaled $3.2 million during 2017, while recoveries of prior period charge-offs totaled $1.8 million. 
Resulting net loan charge-offs equaled $1.4 million, or only 0.06% of average total loans.  Gross loan charge-offs equaled 
$2.2 million during 2016, while recoveries of prior period charge-offs totaled $1.6 million. Resulting net loan charge-offs 
equaled $0.6 million, or only 0.03% of average total loans.  We continue our collection efforts on charged-off loans, and 
expect to record recoveries in future periods; however, given the nature of these efforts, it is not practical to forecast the 
dollar amount and timing of recoveries.

The decline in the ratio of our allowance to nonperforming loans during 2014 primarily reflects the aforementioned one 
distressed commercial loan relationship that was placed into nonaccrual status in late 2014 but resolved during mid-2015. 

In each accounting period, we adjust the allowance to the amount we believe is necessary to maintain the allowance at an 
adequate level.  Through the loan review and credit departments, we establish specific portions of the allowance based on 
specifically identifiable problem loans.  The evaluation of the allowance is further based on, but not limited to, 
consideration of the internally prepared Allowance Analysis, loan loss migration analysis, composition of the loan 
portfolio, third party analysis of the loan administration processes and portfolio, and general economic conditions. 

The Allowance Analysis applies reserve allocation factors to non-impaired outstanding loan balances, the result of which is 
combined with specific reserves to calculate an overall allowance amount.  For non-impaired commercial loans, reserve 
allocation factors are based on the loan ratings as determined by our standardized grade paradigms and by loan purpose.  
Our commercial loan portfolio is segregated into five classes: 1) commercial and industrial loans; 2) vacant land, land 
development and residential construction loans; 3) owner occupied real estate loans; 4) non-owner occupied real estate 
loans; and 5) multi-family and residential rental property loans.  The reserve allocation factors are primarily based on the 
historical trends of net loan charge-offs through a migration analysis whereby net loan losses are tracked via assigned 
grades over various time periods, with adjustments made for environmental factors reflecting the current status of, or recent 
changes in, items such as: lending policies and procedures; economic conditions; nature and volume of the loan portfolio; 
experience, ability and depth of management and lending staff; volume and severity of past due, nonaccrual and adversely 
classified loans; effectiveness of the loan review program; value of underlying collateral; lending concentrations; and other 
external factors, including competition and regulatory environment. Adjustments for specific lending relationships, 
particularly impaired loans, are made on a case-by-case basis.  Non-impaired retail loan reserve allocations are determined 
in a similar fashion as those for non-impaired commercial loans, except that retail loans are segmented by type of credit and 
not a grading system.  We regularly review the Allowance Analysis and make adjustments periodically based upon 
identifiable trends and experience.

A migration analysis is completed quarterly to assist us in determining appropriate reserve allocation factors for non-
impaired loans.  Our migration takes into account various time periods; however, at year-end 2017 we placed most weight 
on the period starting December 31, 2010 through December 31, 2017.  We believe this period represents an appropriate 
range of economic conditions, and that it provides for an appropriate basis in determining reserve allocation factors given 
current economic conditions and the general market consensus of economic conditions in the near future. 

Although the migration analysis provides an accurate historical accounting of our net loan losses, it is not able to fully 
account for environmental factors that will also very likely impact the collectability of our loans as of any quarter-end date.  
Therefore, we incorporate the environmental factors as adjustments to the historical data.  Environmental factors include 
both internal and external items.  We believe the most significant internal environmental factor is our credit culture and the 
relative aggressiveness in assigning and revising commercial loan risk ratings, with the most significant external 
environmental factor being the assessment of the current economic environment and the resulting implications on our loan 
portfolio. 

The primary risk elements with respect to commercial loans are the financial condition of the borrower, the sufficiency of 
collateral, and the timeliness of scheduled payments.  We have a policy of requesting and reviewing periodic financial 
statements from commercial loan customers, and we have a disciplined and formalized review of the existence of collateral 
and its value.  The primary risk element with respect to each residential real estate loan and consumer loan is the timeliness 
of scheduled payments.  We have a reporting system that monitors past due loans and have adopted policies to pursue 
creditor’s rights in order to preserve our collateral position.  

The allowance for originated loans equaled $19.1 million as of December 31, 2017, or 0.9% of total originated loans 
outstanding, compared to 1.0% at year-end 2016.  The allowance for acquired loans equaled $0.4 million as of December 
31, 2017, compared to $0.1 million at year-end 2016.  As of December 31, 2017, the allowance for originated loans was 
comprised of $17.3 million in general reserves relating to non-impaired loans, $1.4 million in specific reserve allocations 
relating to nonaccrual loans, and $0.4 million in specific allocations on other loans, primarily accruing loans designated as 
troubled debt restructurings.   

Although we believe the allowance is adequate to absorb losses as they arise, there can be no assurance that we will not 
sustain losses in any given period that could be substantial in relation to, or greater than, the size of the allowance. 

Troubled debt restructurings totaled $8.6 million at December 31, 2017, consisting of $2.5 million that are on nonaccrual 
status and $6.1 million that are on accrual status.  The latter, while considered and accounted for as impaired loans in 
accordance with accounting guidelines, is not included in our nonperforming loan totals. Impaired loans with an aggregate 
carrying value of $0.9 million as of December 31, 2017 had been subject to previous partial charge-offs aggregating $1.4 
million. Those partial charge-offs were recorded as follows: $0.7 million in 2017, less than $0.1 million in 2016, 2015, 
2013 and 2012, $0.4 million in 2011 and $0.2 million in 2010.  As of December 31, 2017, specific reserves allocated to 
impaired loans that had been subject to a previous partial charge-off totaled less than $0.1 million.

Securities available for sale increased $7.7 million during 2017, totaling $336 million as of December 31, 2017.  The 
securities portfolio equaled 11.3% of average earning assets during 2017.  During 2017, purchases of U.S. Government 
agency bonds totaled $35.6 million, U.S. Government agency issued or guaranteed mortgage-backed securities aggregated 
$10.2 million and municipal bonds totaled $21.2 million.  Proceeds from matured and called U.S. Government agency and 
municipal bonds during 2017 totaled $18.8 million and $20.6 million, respectively, with another $13.0 million from 
principal paydowns on mortgage-backed securities.  In addition, proceeds from the sales of U.S. Government agency issued 
or guaranteed mortgage-backed securities and municipal bonds totaled $5.0 million and $2.6 million, respectively.  At 
December 31, 2017, the securities portfolio was primarily comprised of U.S. Government agency bonds (51%), municipal 
bonds (37%) and U.S. Government agency issued or guaranteed mortgage-backed securities (12%).  All of our securities 
are currently designated as available for sale, and therefore are stated at fair value.  The fair value of securities designated 
as available for sale at December 31, 2017 totaled $336 million, including a net unrealized loss of $6.2 million.  We 
maintain the securities portfolio at levels to provide adequate pledging and secondary liquidity for our daily operations. In 
addition, the securities portfolio serves a primary interest rate risk management function.

FHLBI stock totaled $11.0 million as of December 31, 2017, compared to $8.0 million as of December 31, 2016.  The $3.0 
million increase reflects stock purchases to support the increased level of FHLBI advances during 2017.  Our investment in 
FHLBI stock is necessary to engage in their advance and other financing programs.  We continue to receive regular 
quarterly cash dividends, and we expect a cash dividend will continue in future quarterly periods. 

Market values on our U.S. Government agency bonds, mortgage-backed securities issued or guaranteed by U.S. 
Government agencies and municipal bonds are determined on a monthly basis with the assistance of a third party vendor.  
Evaluated pricing models that vary by type of security and incorporate available market data are utilized.  Standard inputs 
include issuer and type of security, benchmark yields, reported trades, broker/dealer quotes and issuer spreads.  The market 
value of certain non-rated securities issued by relatively small municipalities generally located within our markets is 
estimated at carrying value.  We believe our valuation methodology provides for a reasonable estimation of market value, 
and that it is consistent with the requirements of accounting guidelines.  Reference is made to Note 18 of the Notes to 
Consolidated Financial Statements for additional information.

Other interest-earning assets, primarily consisting of excess funds deposited with the Federal Reserve Bank of Chicago, are 
used to manage daily liquidity needs and interest rate sensitivity.  The average balance of these funds equaled 3.1% of 
average earning assets during 2017, compared to 2.8% during 2016.  We anticipate the level of these earning assets to 
average approximately 2% of average earning assets in future periods. 

Non-Earning Assets 
Cash and due from bank balances averaged 1.6% of total assets during 2017, with no significant changes expected in future 
periods.  Net premises and fixed assets equaled $46.0 million as of December 31, 2017, or 1.4% of total assets.  Net 
purchases during 2017 totaled $5.4 million, while depreciation expense aggregated to $3.0 million.  Foreclosed and 
repossessed assets totaled $2.3 million at December 31, 2017, compared to $0.5 million at December 31, 2016; the $1.8 
million increase during the current year primarily reflects the transfer of a bank-owned parcel of real estate, which is no 
longer being considered for use as a bank facility, in the amount of $1.6 million from fixed assets to other real estate 
owned.  The parcel of real estate is expected to be sold in the next six months for an amount that approximates current book 
value.  While we expect further transfers from loans to foreclosed and repossessed assets in future periods reflecting our 
collection efforts on some impaired lending relationships, we believe the strong quality of our loan portfolio will limit any 
overall increase in, and average balance of, this nonperforming asset category. 

Source of Funds 
Total deposits increased $147 million during 2017, totaling $2.52 billion as of December 31, 2017.  Out-of-area deposits 
increased $26.5 million during 2017, and equaled 4.1% of total deposits at year-end 2017, compared to 3.2% as of 
December 31, 2016.  FHLBI advances increased $45.0 million during 2017, totaling $220 million as of December 31, 
2017. 

Noninterest-bearing checking accounts increased $55.8 million during 2017, generally due to deposit account openings as 
part of recently established commercial lending relationships and transfers from sweep accounts to new noninterest-bearing 
checking accounts reflecting updated interest rate and fee structures.  Interest-bearing checking accounts increased $9.8 
million, while savings deposits declined $17.5 million, the latter primarily reflecting typical fluctuations in certain public 
unit savings accounts.  Money market deposit accounts increased $155 million during 2017, while local time deposits 
decreased $82.3 million, in large part reflecting one depositor transferring their funds from time deposits to money market 
deposit accounts.  This negotiated transfer was completed at the request of the depositor to ease recordkeeping burdens; 
although the funds are no longer in time deposit products, we believe the stability of this long-standing deposit relationship 
is unchanged.  In addition, money market deposit accounts increased due to an enhanced high balance money market 
deposit account product offering that was initiated in mid-2017.

Sweep accounts decreased $13.0 million during 2017, totaling $119 million as of December 31, 2017.  The decline 
primarily reflects certain customers transferring funds from the sweep product to noninterest-bearing checking accounts 
reflecting updated interest rate and fee structures.  Our sweep account program entails transferring collected funds from 
certain business noninterest-bearing checking accounts to overnight interest-bearing repurchase agreements.  Such 
repurchase agreements are not deposit accounts and are not afforded federal deposit insurance.  All of our repurchase 
agreements are accounted for as secured borrowings.  

FHLBI advances increased $45.0 million during 2017, totaling $220 million as of December 31, 2017.  FHLBI advances 
are primarily used to assist in funding loan demand, as well as playing an integral role in our interest rate risk management 
program.  FHLBI advances are generally collateralized by a blanket lien on our residential mortgage loan portfolio.  Our 
borrowing line of credit at year-end 2017 totaled $731 million, with availability of $511 million. 

Shareholders’ equity increased $25.1 million during 2017, totaling $366 million as of December 31, 2017.  Positively 
impacting shareholders’ equity was net income of $31.3 million, while negatively affecting shareholders’ equity were cash 
dividends on our common stock totaling $12.0 million.  Activity relating to the issuance and sale of common stock through 
various stock-based compensation programs and our dividend reinvestment plan positively impacted shareholders’ equity 
by a total of $2.3 million. 

RESULTS OF OPERATIONS 
FOR THE YEARS ENDED DECEMBER 31, 2017 and 2016 

Summary 
We recorded net income of $31.3 million, or $1.90 per basic and diluted share, for 2017, compared to net income of $31.9 
million, or $1.96 per basic and diluted share, for 2016.  Excluding the impacts of certain one-time transactions, net income 
was $31.2 million, or $1.89 per basic and diluted share, in 2017, and $28.7 million, or $1.76 per basic and diluted share, in 
2016.  A bank owned life insurance death benefit claim in the first quarter of 2017 increased net income during 2017 by 
$1.4 million, or $0.09 per basic and diluted share, while the revaluation of the net deferred tax asset in response to the Tax 
Cuts and Jobs Act becoming law in December 2017 decreased net income in the current year by $1.3 million, or $0.08 per 
basic and diluted share.  The repurchase of $11.0 million in trust preferred securities at a 27% discount during the first 
quarter of 2016 increased net income during 2016 by $1.8 million, or $0.11 per basic and diluted share.  We also recorded 
accelerated discount accretion on called U.S. Government agency bonds during 2016 that increased net income by $1.4 
million, or $0.09 per basic and diluted share. 

Our earnings performance in 2017 benefited from increased net interest income, which more than offset increased 
noninterest expense.  The increased net interest income resulted from a higher level of average earning assets.  The 
increased noninterest expense was primarily attributable to expected increases in various operating expenses stemming 
from recent expansion initiatives and increased salary expense, mainly reflecting annual employee merit pay increases, the 
hiring of additional staff, a larger bonus accrual, and greater stock-based compensation expense.  Growth in our primary 
noninterest income revenue streams, including treasury management income, credit and debit card interchange fees, 
mortgage banking activity income, payroll processing revenue, and customer service fees, also contributed to the improved 
earnings performance. 

The following table shows some of the key performance and equity ratios for the years ended December 31, 2017 and 
2016:

Net Interest Income 
Net interest income, the difference between revenue generated from earning assets and the interest cost of funding those 
assets, is our primary source of earnings.  Interest income (adjusted for tax-exempt income) and interest expense totaled 
$126 million and $15.8 million during 2017, respectively, providing for net interest income of $111 million.  During 2016, 
interest income and interest expense equaled $119 million and $12.6 million, respectively, providing for net interest income 
of $107 million.

In comparing 2017 with 2016, interest income increased 6.0%, interest expense was up 25.5%, and net interest income 
increased 3.7%.  The level of net interest income is primarily a function of asset size, as the weighted average interest rate 
received on earning assets is greater than the weighted average interest cost of funding sources; however, factors such as 
types and levels of assets and liabilities, the interest rate environment, interest rate risk, asset quality, liquidity, and 
customer behavior also impact net interest income as well as the net interest margin. 

The $3.9 million increase in net interest income in 2017 compared to 2016 resulted from a higher level of average earning 
assets, which more than offset a lower net interest margin.  During 2017, earning assets averaged $2.92 billion, or $152 
million higher than average earning assets during 2016.  Average loans increased $138 million, average other interest-
earning assets increased $13.1 million, and average securities increased $0.6 million.  During 2017, the net interest margin 
equaled 3.79%, down from 3.86% during 2016 due to a higher cost of funds, which more than offset an increased yield on 
average earning assets.  The higher cost of funds primarily resulted from increased costs of certain non-time deposits, time 
deposits, and borrowed funds. The improved yield on average earning assets mainly resulted from an increased yield on 
loans, primarily reflecting higher interest rates on variable-rate commercial loans stemming from recent Federal Open 
Market Committee (“FOMC”) rate hikes, which more than offset a decreased yield on securities, mainly reflecting a 
decreased level of accelerated purchase discount accretion on called U.S. Government agency bonds. 

The following table depicts the average balance, interest earned and paid, and weighted average rate of our assets, liabilities 
and shareholders’ equity during 2017, 2016 and 2015.  The subsequent table also depicts the dollar amount of change in 
interest income and interest expense of interest-earning assets and interest-bearing liabilities, respectively, segregated 
between change due to volume and change due to rate.  For tax-exempt investment securities, interest income and yield 
have been computed on a tax equivalent basis using a marginal tax rate of 35%.  Securities interest income was increased 
by $0.8 million in both 2017 and 2016 and $0.6 million in 2015 for this non-GAAP, but industry standard, adjustment.  
This adjustment equated to a three basis point increase in our net interest margin during both 2017 and 2016 and a two 
basis point increase in our net interest margin during 2015.

Interest income is primarily generated from the loan portfolio, and to a significantly lesser degree, from securities and other 
interest-earning assets.  Interest income increased $7.1 million during 2017 from that earned in 2016, totaling $126 million 
in 2017 compared to $119 million in the previous year.  The increase in interest income is primarily attributable to a higher 
level of average earning assets; a slightly higher yield on average earning assets also contributed to the increased interest 
income.  During 2017 and 2016, earning assets had an average yield (tax equivalent-adjusted basis) of 4.33% and 4.31%, 
respectively.  The improved yield on average earning assets mainly resulted from an increased yield on loans, primarily 
reflecting higher interest rates on variable-rate commercial loans stemming from the previously-mentioned FOMC rate 
hikes, which more than offset a decreased yield on securities, mainly reflecting a decreased level of accelerated purchase 
discount accretion on called U.S. Government agency bonds.  A change in earning asset mix also contributed to the 
increased yield on average earning assets; average loans represented 85.2% of average earning assets during 2017, up from 
84.9% during 2016. 

Interest income generated from the loan portfolio increased $7.8 million in 2017 compared to the level earned in 2016; 
growth in the loan portfolio during 2017 resulted in a $6.5 million increase in interest income, while an increase in loan 
yield from 4.65% in 2016 to 4.70% in 2017 resulted in a $1.3 million increase in interest income.  The higher yield on 
loans mainly resulted from an increased yield on commercial loans, which more than offset a decreased yield on residential 
mortgage loans.  The yield on commercial loans equaled 4.70% during 2017, up from 4.60% during 2016 as the positive 
impacts of the FOMC rate hikes in December 2016 and March, June, and December 2017 more than offset the negative 
impacts of loans being originated and renewed at lower rates in light of the ongoing relatively low interest rate environment 
and competitive pressures.  The decline in the yield on residential mortgage loans from 5.10% during 2016 to 4.70% during 
2017 primarily reflected the booking of adjustable-rate mortgages with initial rates that were generally lower than the 
existing portfolio’s average rate.  Interest income on acquired loans totaled $4.6 million in 2017, compared to $4.9 million 
in 2016.

Interest income generated from the securities portfolio decreased $1.3 million in 2017 compared to the level earned in 
2016; a decline in the yield on securities from 2.87% during 2016 to 2.47% during 2017 resulted in a $1.4 million decrease 
in interest income, while an increase in the average balance of the securities portfolio resulted in an increase in interest 
income of less than $0.1 million.  The decreased yield on securities mainly reflects a lower level of accelerated discount 
accretion on called U.S. Government agency bonds being recorded as interest income.  The accelerated discount accretion 
totaled $2.2 million during 2016, positively impacting the net interest margin by eight basis points; a nominal level of 
accelerated discount accretion was recorded as interest income during 2017.  Interest income on other interest-earning 
assets increased $0.7 million primarily due to an increased yield. 

Interest expense is primarily generated from interest-bearing deposits, and to a lesser degree, from borrowed funds.  Interest 
expense increased $3.2 million during 2017 from that expensed in 2016, totaling $15.8 million in 2017 compared to $12.6 
million in the previous year.  The increase in interest expense resulted from a higher cost of funds and an increase in 
interest-bearing liabilities.  During 2017 and 2016, interest-bearing liabilities had a weighted average rate of 0.80% and 
0.66%, respectively; an increase in interest expense of $2.7 million was recorded during 2017 due to the higher cost of 
funds.  The higher weighted average cost of interest-bearing liabilities mainly resulted from increased costs of certain 
interest-bearing non-time deposits, time deposits, and borrowed funds.  The cost of interest-bearing non-time deposit 
accounts increased from 0.10% during 2016 to 0.28% during 2017, primarily reflecting one large depositor transferring 
funds from time deposits into a money market account product at rates higher than the average rate on the money market 
product at the time of transfer and the offering of a high balance money market account product with a higher rate.  The 
cost of time deposits increased from 1.14% during 2016 to 1.24% during 2017, primarily reflecting higher costs of public 
unit certificates of deposit $100,000 and over and brokered certificates of deposit $100,000 and over.  The cost of borrowed 
funds increased from 1.45% during 2016 to 1.68% during 2017 primarily due to a change in borrowing mix and an 
increased cost of FHLBI advances.  Average lower-costing sweep accounts represented 30.4% of average borrowed funds 
during 2017, down from 42.9% during 2016, while average higher-costing FHLBI advances represented 56.9% and 43.0% 
of average borrowed funds during the respective periods.  Longer-term FHLBI advances totaling $90 million were obtained 
during 2017 to meet loan funding and interest rate risk management needs.  Average interest-bearing liabilities were $1.97 
billion during 2017, up $57.7 million, or 3.0%, from the $1.91 billion average during 2016. 

An increase in interest-bearing non-time deposits during 2017, totaling $82.5 million, equated to an increase in interest 
expense of $0.1 million, while a higher average rate paid on these deposit accounts resulted in a $1.9 million increase in 
interest expense.  Average time deposits decreased $60.5 million during 2017, in large part reflecting the aforementioned 
transfer of funds into a money market account product; the decreased balance equated to a decline in interest expense of 
$0.7 million.  A $0.5 million increase in interest expense resulted from a higher average rate paid on time deposits. 

Average short-term borrowings, comprised entirely of sweep accounts, declined $32.5 million during 2017, resulting in a 
$0.1 million decrease in interest expense, while a higher average rate paid on these accounts resulted in a nominal increase 
in interest expense.  Average FHLBI advances increased $68.5 million, resulting in a $1.1 million increase in interest 
expense, while a higher average rate paid on the advances resulted in a $0.3 million increase in interest expense.  A $0.3 
million decrease in average other borrowings, coupled with a slight increase in the average rate paid on these borrowings, 
resulted in a nominal increase in interest expense. 

Net interest income and the net interest margin during 2017 and 2016 were also affected by purchase accounting accretion 
and amortization entries associated with the fair value measurements recorded effective June 1, 2014.  Increases in interest 
income on loans totaling $4.6 million and $4.9 million were recorded during 2017 and 2016, respectively.  An increase in 
interest expense on subordinated debentures totaling $0.7 million was recorded during both 2017 and 2016.  Purchased loan 
accretion amounts vary from period to period as a result of periodic cash flow re-estimations, loan payoffs, and payment 
performance. 

Provision for Loan Losses 
A loan loss provision expense of $3.0 million was recorded in 2017, compared to a provision expense of $2.9 million 
recorded in 2016.  The provision expense recorded during 2017 primarily reflects ongoing loan growth and an assessment 
change in our economic conditions environmental factor, while the provision expense incurred during 2016 mainly reflects 
loan growth and an assessment change in our concentrations environmental factor.

Net loan charge-offs of $1.4 million were recorded during 2017, compared to $0.6 million during the prior year.  The 
allowance for originated loans, as a percentage of total originated loans, was 0.9% and 1.0% as of December 31, 2017 and 
December 31, 2016, respectively.  Our allowance for acquired loans totaled $0.4 million and $0.1 million as of December 
31, 2017 and December 31, 2016, respectively. 

Noninterest Income 
Noninterest income totaled $19.0 million in 2017, a decrease of $2.0 million, or 9.7%, from the $21.0 million earned in 
2016.  Our primary noninterest income revenue streams, including treasury management income, credit and debit card 
interchange fees, mortgage banking activity income, payroll processing revenue, and customer service fees, increased $1.2 
million, or 8.5%, on a combined basis in 2017 compared to the prior year.  The increase in mortgage banking activity 
income primarily reflects the positive impact of strategic initiatives that were implemented in the latter half of 2016 and 
throughout 2017, including the hiring of additional loan originators, introduction of new and enhanced products, loan 
programs and increased marketing efforts.  Noninterest income during both 2017 and 2016 benefited from certain one-time 
transactions, including a $1.4 million bank owned life insurance death benefit claim in 2017 and a $2.9 million pre-tax gain 
associated with a trust preferred securities repurchase transaction and $0.4 million in reimbursements related to certain 
medical insurance premiums charged in prior years in 2016. 

Noninterest Expense 
Noninterest expense during 2017 totaled $79.7 million, an increase of $2.6 million, or 3.4%, from the $77.1 million 
expensed in 2016.  The higher level of expense primarily resulted from increased salary expense and expected increases in 
various operating expenses stemming from recent expansion initiatives.  Salary expense was $37.2 million during 2017, an 
increase of $2.7 million, or 7.8%, from the $34.5 million expensed during 2016.  The increased salary expense primarily 
reflects annual employee merit pay increases, the hiring of additional staff, a larger bonus accrual, and greater stock-based 
compensation expense.  A significant portion of the increased salary expense resulting from staff additions reflects the 
opening of the southeast Michigan office.  Employee benefit costs during 2017 were $8.2 million, a decrease of $0.8 
million, or 9.0%, from the $9.0 million expensed in 2016, primarily reflecting lower health insurance costs.  Occupancy 
and furniture and equipment costs increased $0.2 million on a combined basis in 2017, mainly resulting from higher 
depreciation expense.  Data processing costs totaled $8.2 million in 2017, up $0.3 million, or 3.6%, from the $7.9 million 
expensed in 2016, primarily reflecting higher costs related to credit and debit card services.  FDIC insurance premiums 
during 2017 were $1.0 million, a decrease of $0.3 million, or 22.3%, from the $1.3 million expensed during 2016; the 
decrease mainly resulted from changes to the deposit insurance assessment calculation that became effective in the third 
quarter of 2016. 

Federal Income Tax Expense 
During 2017, we recorded income before federal income tax of $46.1 million and a federal income tax expense of $14.8 
million, compared to income before federal income tax of $46.9 million and a federal income tax expense of $15.0 million 
during 2016.  Our effective tax rate was 32.1% during 2017, compared to 31.9% during 2016.  The decrease in federal 
income tax expense during 2017 compared to 2016 period resulted from the lower level of income before federal income 
tax.  The higher effective tax rate in 2017 compared to the prior year reflects the impact of the revaluation of our net 
deferred tax asset in response to the Tax Cuts and Jobs Act, which resulted in increased federal income tax expense of $1.3 
million in the current year.  The aforementioned nontaxable bank owned life insurance death benefit claim positively 
impacted the effective tax rate in 2017. 

RESULTS OF OPERATIONS 
FOR THE YEARS ENDED DECEMBER 31, 2016 and 2015 

Summary 
We recorded net income of $31.9 million, or $1.96 per basic and diluted share, for 2016, compared to net income of $27.0 
million, or $1.63 per basic share and $1.62 per diluted share, for 2015.  The repurchase of $11.0 million in trust preferred 
securities at a 27% discount during the first quarter of 2016 increased net income during 2016 by $1.8 million, or $0.11 per 
basic and diluted share.  This unique opportunity resulted from a private investment fund that voluntarily liquidated and 
auctioned all of its investments.  We also recorded accelerated discount accretion on called U.S. Government agency bonds 
that increased net income by $1.4 million, or $0.09 per basic and diluted share.  Provision expense was $2.9 million, or 
$0.12 per basic and diluted share after tax in 2016, compared to negative $1.0 million, or $0.04 per basic and diluted share 
after tax in 2015.

The improved earnings performance in 2016 compared to 2015 resulted from increased net interest income and noninterest 
income and decreased overhead costs, which more than offset increased provision expense.  The increased net interest 
income primarily resulted from a higher level of average earning assets; an improved net interest margin, resulting from an 
increased yield on total earning assets, also contributed to the higher level of net interest income.  The increased noninterest 
income mainly resulted from the recording of a pre-tax gain associated with the trust preferred securities repurchase 
transaction in January of 2016 and higher service charges on deposit and sweep accounts.  The decreased noninterest 
expense was primarily attributable to decreased problem asset costs, loan processing costs, and Federal Deposit Insurance 
Corporation (“FDIC”) insurance premiums and various cost reduction initiatives, including the cost efficiency program 
announced during the fourth quarter of 2015; the quarterly cost savings associated with the program were fully realized 
beginning in the second quarter of 2016.  The higher provision expense mainly resulted from ongoing loan growth and 
increased allocations related to environmental factors.

Net Interest Income 
Net interest income, the difference between revenue generated from earning assets and the interest cost of funding those 
assets, is our primary source of earnings.  Interest income (adjusted for tax-exempt income) and interest expense totaled 
$119 million and $12.6 million during 2016, respectively, providing for net interest income of $107 million.  During 2015, 
interest income and interest expense equaled $113 million and $11.2 million, respectively, providing for net interest income 
of $102 million.  

In comparing 2016 with 2015, interest income increased 5.6%, interest expense was up 12.9%, and net interest income 
increased 4.8%.  The level of net interest income is primarily a function of asset size, as the weighted average interest rate 
received on earning assets is greater than the weighted average interest cost of funding sources; however, factors such as 
types and levels of assets and liabilities, the interest rate environment, interest rate risk, asset quality, liquidity, and 
customer behavior also impact net interest income as well as the net interest margin. 

The $4.9 million increase in net interest income in 2016 compared to 2015 resulted from a higher level of average earning 
assets, and to a lesser degree, an improved net interest margin.  During 2016, earning assets averaged $2.76 billion, or $110 
million higher than average earning assets during 2015.  Average loans increased $167 million, average securities 
decreased $55.9 million, and average other interest-earning assets decreased $1.1 million.  During 2016, the net interest 
margin equaled 3.86%, up from 3.83% during 2015 due to an increased yield on average earning assets, which more than 
offset a higher cost of funds.  The increased yield on average earning assets primarily resulted from a higher yield on 
securities and a reallocation of earning assets, which more than offset a decreased yield on loans.  The higher yield on 
securities mainly reflects a significant level of accelerated discount accretion on called U.S. Government agency bonds 
being recorded as interest income, while the decreased yield on loans primarily reflects the ongoing low interest rate 
environment and competitive industry pressures.  The yield on loans generally declined over the past ten quarters, 
consistent with the industry; however, the negative impact of the lower loan yield on the yield on average earning assets 
was somewhat offset by the aforementioned reallocation of earning assets.  Capitalizing on an opportunity stemming from 
the 2014 merger with Firstbank, the earning asset mix was reallocated by reinvesting cash flows from monthly paydowns 
on lower-yielding mortgage-backed securities and matured and called U.S. Government Agency bonds into the higher-
yielding loan portfolio.  The reallocation of earning assets strategy was completed during the second quarter of 2016 as the 
level of investments reached our internal policy guideline.

Interest income is primarily generated from the loan portfolio, and to a significantly lesser degree, from securities and other 
interest-earning assets.  Interest income increased $6.3 million during 2016 from that earned in 2015, totaling $119 million 
in 2016 compared to $113 million in the previous year.  The increase in interest income is attributable to a higher level of 
average earning assets and an increased yield on average earning assets.  During 2016 and 2015, earning assets had an 
average yield (tax equivalent-adjusted basis) of 4.31% and 4.25%, respectively.  The higher yield on average earning assets 
in 2016 primarily resulted from an increased yield on securities and a reallocation of earning assets, which more than offset 
a decreased yield on loans.  The higher-yielding loan portfolio averaged $2.35 billion, or 84.9% of average earning assets, 
during 2016, compared to $2.18 billion, or 82.1% of average earning assets, during 2015. 

Interest income generated from the loan portfolio increased $4.9 million in 2016 compared to the level earned in 2015; 
growth in the loan portfolio during 2016 resulted in a $7.8 million increase in interest income, while a decline in loan yield 
from 4.78% in 2015 to 4.65% in 2016 resulted in a $2.9 million decrease in interest income.  The lower yield on average 
loans mainly resulted from a decreased yield on average commercial loans, which equaled 4.60% in 2016 compared to 
4.70% in 2015.  The decreased commercial loan yield primarily reflects the ongoing low interest rate environment and 
competitive pressures.  Accretion of acquired loans totaled $4.9 million during 2016, compared to $5.3 million during 
2015. 

Interest income generated from the securities portfolio increased $1.2 million in 2016 compared to the level earned in 2015; 
an increase in the yield on securities from 2.16% during 2015 to 2.87% during 2016 resulted in a $2.5 million increase in 
interest income, while a reduction in the securities portfolio resulted in a $1.3 million decrease in interest income.  The 
increased yield on securities mainly reflects a significant level of accelerated discount accretion on called U.S. Government 
agency bonds being recorded as interest income.  The accelerated discount accretion totaled $2.2 million during 2016, 
positively impacting the net interest margin by eight basis points.  A nominal level of accelerated discount accretion on 
called U.S. Government agency bonds was recorded as interest income during 2015.  Interest income on interest-earning 
deposits increased $0.2 million primarily due to an increased yield. 

Interest expense is primarily generated from interest-bearing deposits, and to a lesser degree, from subordinated debentures, 
FHLBI advances, sweep accounts, and other borrowings. Interest expense increased $1.4 million during 2016 from that 
expensed in 2015, totaling $12.6 million in 2016 compared to $11.2 million in the previous year.  The increase in interest 
expense is attributable to a higher cost of funds.  During 2016 and 2015, interest-bearing liabilities had a weighted average 
rate of 0.66% and 0.58%, respectively; an increase in interest expense of $1.3 million was recorded during 2016 due to the 
higher cost of funds.  The higher weighted average cost of interest-bearing liabilities mainly resulted from an increased cost 
of certificates of deposit, which more than offset decreases in the costs of certain interest-bearing non-certificate of deposit 
account categories.  The higher cost of certificates of deposit was expected in light of purchase accounting amortization 
entries, which were associated with fair value measurements recorded on the merger date, ending in July of 2015.  A $1.4 
million reduction in interest expense on certificates of deposit related to purchase accounting entries was recorded during 
2015; no reduction in interest expense was recorded during 2016.  Increased rates paid on certificates of deposit, 
subordinated debentures, and FHLBI advances also contributed to the higher weighted average cost of interest-bearing 
liabilities during 2016.  The cost of interest-bearing non-certificate of deposit accounts decreased from 0.15% during 2015 
to 0.10% during 2016 in light of rates being lowered during the latter part of 2015.  Average interest-bearing liabilities were 
$1.91 billion during 2016, down $18.1 million, or 0.9%, from the $1.93 billion average during 2015. 

Average certificates of deposit decreased $80.9 million during 2016, which equated to a decline in interest expense of $0.8 
million.  A $1.3 million increase in interest expense resulted from a higher average rate paid on certificates of deposit, 
primarily reflecting the impact of the purchase accounting amortization entries ending in July of 2015.  A decrease in other 
average interest-bearing deposit accounts, totaling $23.4 million, equated to a decrease in interest expense of less than $0.1 
million, while a decrease in the average rate paid on these deposit accounts resulted in a $0.5 million decline in interest 
expense. 

Average short-term borrowings, comprised entirely of sweep accounts, increased $2.3 million during 2016, resulting in a 
nominal increase in interest expense, while a higher average rate paid on these accounts resulted in a $0.1 million increase 
in interest expense.  Average FHLBI advances increased $93.8 million, resulting in a $1.4 million increase in interest 
expense, while a higher average rate paid on the advances resulted in a $0.1 million increase in interest expense.  A $9.8 
million decrease in average other borrowings, which is comprised of subordinated debentures and deferred director and 
officer compensation programs, equated to a $0.5 million decline in interest expense, while a higher average rate paid on 
these borrowings resulted in a $0.4 million increase in interest expense.

Net interest income and the net interest margin during 2016 and 2015 were affected by purchase accounting accretion and 
amortization entries associated with the fair value measurements recorded on June 1, 2014.  An increase in interest income 
on loans totaling $4.9 million and an increase in interest expense on subordinated debentures totaling $0.7 million were 
recorded during 2016.  During 2015, we recorded an increase in interest income on loans totaling $5.3 million and a 
decrease in interest expense on deposits and FHLBI advances totaling $1.4 million.  In addition, we recorded an increase in 
interest expense on subordinated debentures totaling $0.7 million during the same time period.  The adjustments to interest 
expense on deposits and FHLBI advances ended in July and June of 2015, respectively.  The resulting increase in interest 
expense negatively impacted the net interest margin by approximately eight to ten basis points after July 31, 2015. 

Provision for Loan Losses 
A loan loss provision expense of $2.9 million was recorded in 2016, compared to a negative provision expense of $1.0 
million recorded in 2015.  The provision expense recorded during 2016 primarily reflects ongoing loan growth and an 
assessment change in our concentrations environmental factor, while the negative provision expense recorded during 2015 
resulted from multiple factors, including recoveries of previously charged-off loans, reversals of specific reserves, a 
reduced level of loan-rating downgrades and ongoing loan-rating upgrades. 

Net loan charge-offs of $0.6 million were recorded during 2016, compared to $3.4 million during the prior year.  Of the 
$6.3 million in gross loan charge-offs recorded during 2015, $4.2 million was related to one commercial loan relationship 
that was resolved during the second quarter of that year.  The allowance for originated loans, as a percentage of total 
originated loans, was 0.9% as of December 31, 2016 and December 31, 2015.  Our allowance for acquired loans totaled 
$0.1 million and $0.5 million as of December 31, 2016 and December 31, 2015, respectively. 

Noninterest Income 
Noninterest income totaled $21.0 million in 2016, an increase of $5.0 million, or 31.2%, from the $16.0 million earned in 
2015.  The increase mainly resulted from a $2.9 million pre-tax gain being recorded in the first quarter of 2016 in 
association with a trust preferred securities repurchase transaction and higher service charges on deposit and sweep 
accounts and mortgage banking income.  Service charges on deposit and sweep accounts totaled $4.3 million during 2016, 
an increase of $1.0 million, or 28.6%, from the $3.3 million recorded during 2015.  The increase in service charges on 
deposit and sweep accounts mainly reflects an ongoing project to ensure all depositors are in a product that best meets their 
needs and is priced appropriately as well as increased cash management fee income.  Mortgage banking income was $3.9 
million in 2016, an increase of $0.3 million, or 6.8%, from the $3.6 million recorded during 2015.  The increase in 
mortgage banking income primarily reflects the positive impact of recently-implemented strategic initiatives, including the 
hiring of additional loan originators, introduction of new and enhanced products, loan programs, and increased marketing 
efforts.  Reimbursements totaling $0.4 million recorded in the third quarter of 2016 related to certain medical insurance 
premiums charged in prior years also contributed to the increase in noninterest income.

Noninterest Expense 
Noninterest expense during 2016 totaled $77.1 million, a decrease of $2.3 million, or 2.9%, from the $79.4 million 
expensed in 2015.  The decrease was mainly attributable to lower problem asset costs, loan processing costs, FDIC 
insurance premiums, core deposit intangible amortization expense, printing and supply costs, furniture and equipment 
costs, and miscellaneous expenses, which more than offset increased employee benefit and data processing costs.  Problem 
asset costs during 2016 were $0.9 million lower than the amount expensed during 2015.  Loan processing costs were $0.5 
million during 2016, a decrease of $0.6 million, or 50.8%, from the $1.1 million expensed during 2015, primarily reflecting 
the elimination of certain retail loan promotion programs.  FDIC insurance premiums during 2016 were $1.2 million, a 
decrease of $0.5 million, or 28.0%, from the $1.7 million expensed during 2015; the decrease resulted from improvements 
in certain financial ratios and changes to the deposit insurance assessment calculation that became effective in the third 
quarter of 2016.  Core deposit intangible amortization expense totaled $2.7 million during 2016, compared to $3.0 million 
during 2015.  Printing and supply costs were $1.1 million in 2016, a decrease of $0.3 million, or 21.3%, from the $1.4 
million expensed during 2015; the decrease primarily resulted from an initiative to convert deposit customers from 
receiving physical account statements to receiving electronic statements and the implementation of a central purchasing 
program.  Furniture and equipment costs were $2.1 million during 2016, a decrease of $0.2 million, or 9.1%, from the $2.3 
million in costs incurred during 2015, mainly reflecting lower depreciation expense.  Noninterest expense during 2016 was 
positively impacted by the cost efficiency program, which will save approximately $2.7 million per year on a pre-tax basis 
beginning in 2017; the quarterly cost savings were fully realized starting in the second quarter of 2016.  Employee benefit 
costs during 2016 were $9.0 million, an increase of $0.4 million, or 4.2%, from the $8.6 million expensed in 2015, 
primarily resulting from higher health insurance costs.  Data processing costs during 2016 totaled $7.9 million, an increase 
of $0.2 million, or 3.2%, from the $7.7 million expensed during 2015, primarily reflecting higher costs related to debit and 
credit card services. 

Federal Income Tax Expense 
During 2016, we recorded income before federal income tax of $46.9 million and a federal income tax expense of $15.0 
million, compared to income before federal income tax of $38.8 million and a federal income tax expense of $11.8 million 
during 2015.  The increase in federal income tax expense resulted from the higher level of income before federal income 
tax.  Our effective tax rate was 31.9% during 2016, compared to 30.4% during 2015. 

CAPITAL RESOURCES 

Shareholders’ equity increased $25.1 million during 2017, totaling $366 million as of December 31, 2017.  Positively 
impacting shareholders’ equity was net income of $31.3 million, while negatively affecting shareholders’ equity were cash 
dividends on our common stock totaling $12.0 million.  Activity relating to the issuance and sale of common stock through 
various stock-based compensation programs and our dividend reinvestment plan positively impacted shareholders’ equity 
by a total of $2.3 million. 

We and our bank are subject to regulatory capital requirements administered by state and federal banking agencies. Failure 
to meet the various capital requirements can initiate regulatory action that could have a direct material effect on the 
financial statements.  As of December 31, 2017, our bank’s total risk-based capital ratio was 12.6%, compared to 13.1% at 
December 31, 2016.  Our bank’s total regulatory capital increased $18.1 million during 2017, primarily reflecting the net 
impact of net income totaling $33.3 million and cash dividends paid to Mercantile Bank Corporation aggregating $16.1 
million.  Our bank’s total risk-based capital ratio was also impacted by a $249 million increase in total risk-weighted assets, 
primarily resulting from net commercial loan growth.  As of December 31, 2017, our bank’s total regulatory capital 
equaled $371 million, or $77.0 million in excess of the amount necessary to attain the 10.0% minimum total risk-based 
capital ratio, which is among the requirements to be categorized as “well capitalized.” 

On January 30, 2015, we announced that our Board of Directors had authorized a new program to repurchase up to $20.0 
million of our common stock from time to time in open market transactions at prevailing market prices or by other means 
in accordance with applicable regulations.  On April 19, 2016, we announced a $15.0 million expansion of the stock 
repurchase plan.  Since inception, we have purchased a total of 956,419 shares at a total price of $19.5 million, at an 
average price per share of $20.38; no shares were purchased under the authorized plan during 2017.  The stock buybacks 
have been funded from cash dividends paid to us from our bank.  Additional repurchases may be made in future periods 
under the authorized plan, which would also likely be funded from cash dividends paid to us from our bank.

LIQUIDITY 

Liquidity is measured by our ability to raise funds through deposits, borrowed funds, capital or cash flow from the 
repayment of loans and securities.  These funds are used to fund loans, meet deposit withdrawals, maintain reserve 
requirements and operate our company. Liquidity is primarily achieved through local and out-of-area deposits and liquid 
assets such as securities available for sale, matured and called securities, federal funds sold and interest-earning deposit 
balances.  Asset and liability management is the process of managing the balance sheet to achieve a mix of earning assets 
and liabilities that maximizes profitability, while providing adequate liquidity. 

To assist in providing needed funds, we regularly obtained monies from wholesale funding sources.  Wholesale funds, 
primarily comprised of deposits from customers outside of our market areas and advances from the FHLBI, totaled $323 
million, or 11.3% of combined deposits and borrowed funds as of December 31, 2017, compared to $251 million, or 9.4% 
of combined deposits and borrowed funds, as of December 31, 2016. 

Sweep accounts decreased $13.0 million during 2017, totaling $119 million as of December 31, 2017.  The decline 
primarily reflects certain customers transferring funds from the sweep product to noninterest-bearing checking accounts 
reflecting updated interest rate and fee structures.  Our sweep account program entails transferring collected funds from 
certain business noninterest-bearing checking accounts to overnight interest-bearing repurchase agreements.  Such 
repurchase agreements are not deposit accounts and are not afforded federal deposit insurance.  All of our repurchase 
agreements are accounted for as secured borrowings.   

Information regarding our repurchase agreements as of December 31, 2017 and during 2017 is as follows:

FHLBI advances increased $45.0 million during 2017, totaling $220 million as of December 31, 2017.  FHLBI advances 
are primarily used to assist in funding loan demand, as well as playing an integral role in our interest rate risk management 
program.  FHLBI advances are generally collateralized by a blanket lien on our residential mortgage loan portfolio.  Our 
borrowing line of credit at year-end 2017 totaled $731 million, with availability of $511 million. 

We also have the ability to borrow up to $50.0 million on a daily basis through a correspondent bank using an established 
unsecured federal funds purchased line of credit.  We accessed this line of credit on two occasions during 2017; prior to 
these borrowings, we had not accessed any federal funds purchased lines of credit since January of 2010.  In contrast, our 
interest-earning deposit account at the Federal Reserve Bank of Chicago averaged $88.4 million during 2017.  We have a 
line of credit through the Discount Window of the Federal Reserve Bank of Chicago.  Using certain municipal bonds as 
collateral, we could have borrowed up to $19.9 million at December 31, 2017.  We did not utilize this line of credit during 
the past seven years, and do not plan to access this line of credit in future periods.

In addition to normal loan funding and deposit flow, we must maintain liquidity to meet the demands of certain unfunded 
loan commitments and standby letters of credit.  At December 31, 2017, we had a total of $986 million in unfunded loan 
commitments and $26.0 million in unfunded standby letters of credit.  Of the total unfunded loan commitments, $801 
million were commitments available as lines of credit to be drawn at any time as customers’ cash needs vary, and $185 
million were for loan commitments generally expected to close and become funded within the next 12 to 18 months.  We 
regularly monitor fluctuations in loan balances and commitment levels, and include such data in our overall liquidity 
management.

We monitor our liquidity position and funding strategies on an ongoing basis, but recognize that unexpected events, 
economic or market conditions, reductions in earnings performance, declining capital levels or situations beyond our 
control could cause liquidity challenges.  While we believe it is unlikely that a funding crisis of any significant degree is 
likely to materialize, we have developed a comprehensive contingency funding plan that provides a framework for meeting 
liquidity disruptions. 

MARKET RISK ANALYSIS 

Our primary market risk exposure is interest rate risk and, to a lesser extent, liquidity risk. All of our transactions are 
denominated in U.S. dollars with no specific foreign exchange exposure.  We have only limited agricultural-related loan 
assets and therefore have no significant exposure to changes in commodity prices.  Any impact that changes in foreign 
exchange rates and commodity prices would have on interest rates is assumed to be insignificant.  Interest rate risk is the 
exposure of our financial condition to adverse movements in interest rates.  We derive our income primarily from the 
excess of interest collected on interest-earning assets over the interest paid on interest-bearing liabilities.  The rates of 
interest we earn on our assets and owe on our liabilities generally are established contractually for a period of time.  Since 
market interest rates change over time, we are exposed to lower profitability if we cannot adapt to interest rate changes.  
Accepting interest rate risk can be an important source of profitability and shareholder value; however, excessive levels of 
interest rate risk could pose a significant threat to our earnings and capital base.  Accordingly, effective risk management 
that maintains interest rate risk at prudent levels is essential to our safety and soundness.  

Evaluating the exposure to changes in interest rates includes assessing both the adequacy of the process used to control 
interest rate risk and the quantitative level of exposure.  Our interest rate risk management process seeks to ensure that 
appropriate policies, procedures, management information systems and internal controls are in place to maintain interest 
rate risk at prudent levels with consistency and continuity.  In evaluating the quantitative level of interest rate risk, we 
assess the existing and potential future effects of changes in interest rates on our financial condition, including capital 
adequacy, earnings, liquidity and asset quality. 

We use two interest rate risk measurement techniques. The first, which is commonly referred to as GAP analysis, measures 
the difference between the dollar amounts of interest-sensitive assets and liabilities that will be refinanced or repriced 
during a given time period.  A significant repricing gap could result in a negative impact to the net interest margin during 
periods of changing market interest rates.

(1)  Floating rate loans that are currently at interest rate floors are treated as fixed rate loans and are reflected using 

maturity date and not repricing frequency. 

(2)  Mortgage-backed securities are categorized by expected maturities based upon prepayment trends as of December 31, 

2017. 

The second interest rate risk measurement used is commonly referred to as net interest income simulation analysis.  We 
believe that this methodology provides a more accurate measurement of interest rate risk than the GAP analysis, and 
therefore, it serves as our primary interest rate risk measurement technique.  The simulation model assesses the direction 
and magnitude of variations in net interest income resulting from potential changes in market interest rates.  

Key assumptions in the model include prepayment speeds on various loan and investment assets; cash flows and maturities 
of interest-sensitive assets and liabilities; and changes in market conditions impacting loan and deposit volume and pricing. 
These assumptions are inherently uncertain, subject to fluctuation and revision in a dynamic environment; therefore, the 
model cannot precisely estimate net interest income or exactly predict the impact of higher or lower interest rates on net 
interest income. Actual results will differ from simulated results due to timing, magnitude, and frequency of interest rate 
changes and changes in market conditions and our strategies, among other factors.

We conducted multiple simulations as of December 31, 2017, in which it was assumed that changes in market interest rates 
occurred ranging from up 400 basis points to down 400 basis points in equal quarterly instalments over the next twelve 
months.  The following table reflects the suggested impact on net interest income over the next twelve months in 
comparison to estimated net interest income based on our balance sheet structure, including the balances and interest rates 
associated with our specific loans, securities, deposits and borrowed funds, as of December 31, 2017.

The resulting estimates have been significantly impacted by the current interest rate and economic environment, as 
adjustments have been made to critical model inputs with regards to traditional interest rate relationships.  This is especially 
important as it relates to floating rate commercial loans and out-of-area deposits, which comprise a sizable portion of our 
balance sheet.  

In addition to changes in interest rates, the level of future net interest income is also dependent on a number of other 
variables, including: the growth, composition and absolute levels of loans, deposits, and other earning assets and interest-
bearing liabilities; level of nonperforming assets; economic and competitive conditions; potential changes in lending, 
investing, and deposit gathering strategies; client preferences; and other factors.

Mercantile Bank Corporation 
Grand Rapids, Michigan 

Opinion on the Consolidated Financial Statements 
We have audited the accompanying consolidated balance sheets of Mercantile Bank Corporation (the “Company”) and 
subsidiaries as of December 31, 2017 and 2016, the related consolidated statements of income, comprehensive income, 
changes in shareholders’ equity, and cash flows for each of the three years in the period ended December 31, 2017, and the 
related notes (collectively referred to as the “consolidated financial statements”).  In our opinion, the consolidated financial 
statements present fairly, in all material respects, the financial position of the Company and subsidiaries at December 31, 
2017 and 2016, and the results of their operations and their cash flows for each of the three years in the period ended 
December 31, 2017, in conformity with accounting principles generally accepted in the United States of America. 

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United 
States) (“PCAOB”), the Company’s internal control over financial reporting as of December 31, 2017, based on criteria 
established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the 
Treadway Commission (“COSO”) and our report dated March 5, 2018 expressed an unqualified opinion thereon. 

Basis for Opinion 
These consolidated financial statements are the responsibility of the Company’s management.  Our responsibility is to 
express an opinion on the Company’s consolidated financial statements based on our audits.  We are a public accounting 
firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the 
U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the 
PCAOB. 

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and 
perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material 
misstatement, whether due to error or fraud.  

Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial 
statements, whether due to error or fraud, and performing procedures that respond to those risks.  Such procedures included 
examining, on a test basis, evidence supporting the amounts and disclosures in the consolidated financial statements.  Our 
audits also included evaluating the accounting principles used and significant estimates made by management, as well as 
evaluating the overall presentation of the consolidated financial statements.  We believe that our audits provide a 
reasonable basis for our opinion.

Board of Directors and Shareholders 
Mercantile Bank Corporation 
Grand Rapids, Michigan 

Opinion on Internal Control over Financial Reporting 
We have audited Mercantile Bank Corporation’s (the “Company’s”) internal control over financial reporting as of 
December 31, 2017, based on criteria established in Internal Control – Integrated Framework (2013) issued by the 
Committee of Sponsoring Organizations of the Treadway Commission (the “COSO criteria”).  In our opinion, the 
Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2017, 
based on the COSO criteria. 

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United 
States) (“PCAOB”), the consolidated balance sheets of the Company as of December 31, 2017 and 2016, the related 
consolidated statements of income, comprehensive income, changes in shareholders’ equity, and cash flows for each of the 
three years in the period ended December 31, 2017, and the related notes, and our report dated March 5, 2018 expressed an 
unqualified opinion thereon. 

Basis for Opinion 
The Company’s management is responsible for maintaining effective internal control over financial reporting and for its 
assessment of the effectiveness of internal control over financial reporting, included in the accompanying Report by 
Mercantile Bank Corporation’s Management on Internal Control over Financial Reporting. Our responsibility is to express 
an opinion on the Company’s internal control over financial reporting based on our audit.  We are a public accounting firm 
registered with the PCAOB and are required to be independent with respect to the Company in accordance with U.S. 
federal securities laws and applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. 

We conducted our audit of internal control over financial reporting in accordance with the standards of the PCAOB. Those 
standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control 
over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal 
control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and 
operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other 
procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our 
opinion. 

Definition and Limitations of Internal Control over Financial Reporting 
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the 
reliability of financial reporting and the preparation of financial statements for external purposes in accordance with 
generally accepted accounting principles.  A company’s internal control over financial reporting includes those policies and 
procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the 
transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded 
as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and 
that receipts and expenditures of the company are being made only in accordance with authorizations of management and 
directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized 
acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements. 

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, 
projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate 
because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

REPORT BY MERCANTILE BANK CORPORATION’S MANAGEMENT 
ON INTERNAL CONTROL OVER FINANCIAL REPORTING 

Management is responsible for establishing and maintaining an effective system of internal control over financial reporting 
that is designed to produce reliable financial statements presented in conformity with generally accepted accounting 
principles. There are inherent limitations in the effectiveness of any system of internal control. Accordingly, even an 
effective system of internal control can provide only reasonable assurance with respect to financial statement preparation. 

Management assessed the Company’s system of internal control over financial reporting that is designed to produce reliable 
financial statements presented in conformity with generally accepted accounting principles as of December 31, 2017. This 
assessment was based on criteria for effective internal control over financial reporting described in Internal Control – 
Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based 
on this assessment, management believes that, as of December 31, 2017, Mercantile Bank Corporation maintained an 
effective system of internal control over financial reporting that is designed to produce reliable financial statements 
presented in conformity with generally accepted accounting principles based on those criteria. 

The Company’s independent auditors have issued an audit report on the effectiveness of the Company’s internal control 
over financial reporting as found on page F-32.

MERCANTILE BANK CORPORATION 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 
December 31, 2017 

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES 

Principles of Consolidation: The consolidated financial statements include the accounts of Mercantile Bank Corporation 
(“Mercantile”) and its subsidiary, Mercantile Bank of Michigan (“Bank”), and of Mercantile Bank Real Estate Co., L.L.C. 
(“Mercantile Real Estate”) and Mercantile Insurance Center, Inc. (“Mercantile Insurance”), subsidiaries of our Bank, after 
elimination of significant intercompany transactions and accounts. 

Mercantile has five separate business trusts: Mercantile Bank Capital Trust I, Firstbank Capital Trust I, Firstbank Capital 
Trust II, Firstbank Capital Trust III and Firstbank Capital Trust IV (“our trusts”). Our trusts were formed to issue trust 
preferred securities. We issued subordinated debentures to our trusts in return for the proceeds raised from the issuance of 
the trust preferred securities. Our trusts are not consolidated, but instead we report the subordinated debentures issued to the 
trusts as liabilities. 

Nature of Operations: Mercantile was incorporated on July 15, 1997 to establish and own the Bank based in Grand Rapids, 
Michigan. The Bank began operations on December 15, 1997. We completed the merger of Firstbank Corporation 
(“Firstbank”), a Michigan corporation with approximately $1.5 billion in total assets and 46 branch locations, into 
Mercantile as of June 1, 2014. 

The Bank is a community-based financial institution. The Bank’s primary deposit products are checking, savings, and term 
certificate accounts, and its primary lending products are commercial loans, residential mortgage loans, and instalment 
loans. Substantially all loans are secured by specific items of collateral including business assets, real estate or consumer 
assets. Commercial loans are expected to be repaid from cash flow from operations of businesses. Real estate loans are 
secured by commercial or residential real estate. The Bank’s loan accounts and retail deposits are primarily with customers 
located in the communities in which we have bank office locations. As an alternative source of funds, the Bank has also 
issued certificates of deposit to depositors outside of its primary market areas. Substantially all revenues are derived from 
banking products and services and investment securities. While we monitor the revenue streams of the various products and 
services offered, we manage our business on the basis of one operating segment, banking. 

Mercantile Real Estate was organized on July 21, 2003, principally to develop, construct, and own a facility in downtown 
Grand Rapids that serves as our Bank’s main office and Mercantile’s headquarters. This facility was placed into service 
during the second quarter of 2005. 

Use of Estimates: To prepare financial statements in conformity with accounting principles generally accepted in the 
United States of America, management makes estimates and assumptions based on available information. These estimates 
and assumptions affect the amounts reported in the financial statements and the disclosures provided, and actual results 
could differ. The allowance for loan losses and the fair values of financial instruments are particularly subject to change. 

Cash Flow Reporting: Cash and cash equivalents include cash on hand, demand deposits with other financial institutions, 
short-term investments (including securities with daily put provisions) and federal funds sold. Cash flows are reported net 
for customer loan and deposit transactions, interest-earning time deposits with other financial institutions and short-term 
borrowings with maturities of 90 days or less. 

Securities: Debt securities classified as held to maturity are carried at amortized cost when management has the positive 
intent and ability to hold them to maturity. Debt securities are classified as available for sale when they might be sold prior 
to maturity. Equity securities with readily determinable fair values are classified as available for sale. Securities available 
for sale are carried at fair value, with unrealized holding gains and losses reported in other comprehensive income, net of 
tax. Federal Home Loan Bank stock is carried at cost.

MERCANTILE BANK CORPORATION 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 
December 31, 2017 

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) 

Interest income includes amortization of purchase premiums and accretion of discounts. Premiums and discounts on 
securities are amortized or accreted on the level-yield method without anticipating prepayments, except for mortgage-
backed securities where prepayments are anticipated. Gains and losses on sales are recorded on the trade date and 
determined using the specific identification method. 

Declines in the fair value of debt securities below their amortized cost that are other than temporary (“OTTI”) are reflected 
in earnings or other comprehensive income, as appropriate. For those debt securities whose fair value is less than their 
amortized cost, we consider our intent to sell the security, whether it is more likely than not that we will be required to sell 
the security before recovery and whether we expect to recover the entire amortized cost of the security based on our 
assessment of the issuer’s financial condition. In analyzing an issuer’s financial condition, we consider whether the 
securities are issued by the federal government or its agencies, and whether downgrades by bond rating agencies have 
occurred. If either of the criteria regarding intent or requirement to sell is met, the entire difference between amortized cost 
and fair value is recognized as impairment through earnings. For debt securities that do not meet the aforementioned 
criteria, the amount of impairment is split into two components as follows: 1) OTTI related to credit loss, which must be 
recognized in the income statement, and 2) OTTI related to other factors, such as liquidity conditions in the market or 
changes in market interest rates, which is recognized in other comprehensive income. The credit loss is defined as the 
difference between the present value of the cash flows expected to be collected and the amortized cost. 

Loans: Loans that we have the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at 
the principal balance outstanding, net of deferred loan fees and costs and an allowance for loan losses. Interest income is 
accrued on the unpaid principal balance. Loan origination fees, net of certain direct origination costs, are deferred and 
recognized in interest income using the level-yield method without anticipating prepayments. Net unamortized deferred 
loan fees amounted to $1.0 million and $1.4 million, respectively, at December 31, 2017 and 2016. 

Interest income on commercial loans and mortgage loans is discontinued at the time the loan is 90 days delinquent unless 
the loan is well-secured and in process of collection. Consumer and credit card loans are typically charged off no later than 
when they are 120 days past due. Past due status is based on the contractual terms of the loan. In all cases, loans are placed 
on nonaccrual or charged off at an earlier date if collection of principal and interest is considered doubtful. 

All interest accrued but not received for loans placed on nonaccrual is reversed against interest income. Interest received on 
such loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual. Loans are 
returned to accrual status when all the principal and interest amounts contractually due are brought current and future 
payments are reasonably assured. 

Loans Held for Sale: Mortgage loans originated and intended for sale in the secondary market are carried at the lower of 
aggregate cost or fair value, as determined by outstanding commitments from investors. Net unrealized losses, if any, are 
recorded as a valuation allowance and charged to earnings. Mortgage loans held for sale are generally sold with servicing 
rights retained. Gains and losses on sales of mortgage loans are based on the difference between the selling price and the 
carrying value of the related mortgage loan sold, which is reduced by the cost allocated to the servicing right. We generally 
lock in the sale price to the purchaser of the mortgage loan at the same time we make an interest rate commitment to the 
borrower.

Mortgage Loan Derivatives: We enter into forward contracts and interest rate lock commitments in the ordinary course of 
business, which are accounted for as derivatives.  The derivatives are not designated as hedges and are carried at fair value. 
The net gain or loss on derivatives is included in mortgage banking activities in the income statement. The balance of 
derivatives was immaterial at December 31, 2017 and 2016. 

Mortgage Banking Activities: Mortgage loan servicing rights are recognized as assets based on the allocated value of 
retained servicing rights on mortgage loans sold. Mortgage loan servicing rights are carried at the lower of amortized cost 
or fair value and are expensed in proportion to, and over the period of, estimated net servicing revenues. Impairment is 
evaluated based on the fair value of the rights using groupings of the underlying mortgage loans as to interest rates. Any 
impairment of a grouping is reported as a valuation allowance. 

Servicing fee income is recorded for fees earned for servicing mortgage loans. The fees are based on a contractual 
percentage of the outstanding principal or a fixed amount per loan and are recorded as income when earned. Amortization 
of mortgage loan servicing rights is netted against mortgage loan servicing income and recorded in mortgage banking 
activities in the statements of income. 

Troubled Debt Restructurings: A loan is accounted for as a troubled debt restructuring if we, for economic or legal reasons, 
grant a concession to a borrower considered to be experiencing financial difficulties that we would not otherwise consider. 
A troubled debt restructuring may involve the receipt of assets from the debtor in partial or full satisfaction of the loan, or a 
modification of terms such as a reduction of the stated interest rate or balance of the loan, a reduction of accrued interest, an 
extension of the maturity date or renewal of the loan at a stated interest rate lower than the current market rate for a new 
loan with similar risk, or some combination of these concessions. Troubled debt restructurings can be in either accrual or 
nonaccrual status. Nonaccrual troubled debt restructurings are included in nonperforming loans. Accruing troubled debt 
restructurings are generally excluded from nonperforming loans as it is considered probable that all contractual principal 
and interest due under the restructured terms will be collected. 

Loans modified as troubled debt restructurings are, by definition, considered to be impaired loans. Impairment for these 
loans is measured on a loan-by-loan basis similar to other impaired loans as described below under “Allowance for Loan 
Losses.” Certain loans modified as troubled debt restructurings may have been previously measured for impairment under a 
general allowance methodology (i.e., pooling), thus at the time the loan is modified as a troubled debt restructuring the 
allowance will be impacted by the difference between the results of these two measurement methodologies. Loans modified 
as troubled debt restructurings that subsequently default are factored into the determination of the allowance for loan losses 
in the same manner as other defaulted loans.

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) 

Allowance for Loan Losses: The allowance for loan losses (“allowance”) is a valuation allowance for probable incurred 
credit losses. Loan losses are charged against the allowance when we believe the uncollectability of a loan is confirmed. 
Subsequent recoveries, if any, are credited to the allowance. We estimate the allowance balance required using past loan 
loss experience, the nature and volume of the loan portfolio, information about specific borrower situations and estimated 
collateral values, economic conditions and other factors. We estimate credit losses based on individual loans determined to 
be impaired and on all other loans grouped on similar risk characteristics. Our historical loss component is the most 
significant of the allowance components and is based on historical loss experience by credit risk grade for commercial 
loans and payment status for mortgage and consumer loans. Loans are pooled based on similar risk characteristics 
supported by observable data. The historical loss experience component of the allowance represents the results of migration 
analysis of historical net charge-offs for portfolios of loans, including groups of commercial loans within each credit risk 
grade. For measuring loss exposure in a pool of loans, the historical net charge-off or migration experience is utilized to 
estimate expected future losses to be realized from the pool of loans. Allocations of the allowance may be made for specific 
loans, but the entire allowance is available for any loan that, in our judgment, should be charged-off. 

A loan is considered impaired when, based on current information and events, it is probable we will be unable to collect the 
scheduled payments of principal and interest when due according to the contractual terms of the loan agreement. Factors 
considered in determining impairment include payment status and collateral value. Loans that experience insignificant 
payment delays and payment shortfalls generally are not classified as impaired. We determine the significance of payment 
delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the 
loan and the borrower, including the length of delay, the reasons for delay, the borrower’s prior payment record and the 
amount of the shortfall in relation to the principal and interest owed. Impairment is measured on a loan-by-loan basis for 
commercial and construction loans by the present value of expected future cash flows discounted at the loan’s effective 
interest rate, the loan’s obtainable market price or the fair value of collateral if the loan is collateral dependent. Large 
groups of smaller balance homogeneous loans are collectively evaluated for impairment. 

Transfers of Financial Assets: Transfers of financial assets are accounted for as sales when control over the assets has been 
surrendered. Control over transferred assets is deemed to be surrendered when: (1) the assets have been isolated from the 
Bank and put presumptively beyond the reach of the transferor and its creditors, even in bankruptcy or other receivership, 
(2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or 
exchange the transferred assets, and (3) the Bank does not maintain effective control over the transferred assets through an 
agreement to repurchase them before their maturity or the ability to unilaterally cause the holder to return specific assets. 
Our transfers of financial assets are generally limited to commercial loan participations sold and residential mortgage loans 
sold in the secondary market. 

Premises and Equipment: Land is carried at cost. Premises and equipment are stated at cost less accumulated depreciation. 
Buildings and related components are depreciated using the straight-line method with useful lives ranging from 5 to 33 
years. Furniture, fixtures and equipment are depreciated using the straight-line method with useful lives ranging from 3 to 7 
years. Maintenance, repairs and minor alterations are charged to current operations as expenditures occur and major 
improvements are capitalized.  

Long-lived Assets: Premises and equipment and other long-lived assets are reviewed for impairment when events indicate 
their carrying amount may not be recoverable based on future undiscounted cash flows. If impaired, the assets are recorded 
at the lower of carrying value or fair value. 

Foreclosed Assets: Assets acquired through or in lieu of foreclosure are initially recorded at their estimated fair value net of 
estimated selling costs, establishing a new cost basis. If fair value subsequently declines, a valuation allowance is recorded 
through noninterest expense, as are collection and operating costs after acquisition. Foreclosed assets, included in other 
assets in the balance sheet, totaled $2.3 million and $0.5 million as of December 31, 2017 and 2016, respectively.

Bank Owned Life Insurance: The Bank has purchased life insurance policies on certain key officers. Bank owned life 
insurance is recorded at its cash surrender value, or the amount that can be realized. 

Goodwill and Core Deposit Intangible: Goodwill results from business acquisitions and represents the excess of the 
purchase price over the fair value of acquired tangible assets and liabilities and identifiable intangible assets. Goodwill is 
assessed at least annually for impairment and any such impairment is recognized in the period identified. A more frequent 
assessment is performed should events or changes in circumstances indicate the carrying value of the goodwill may not be 
recoverable. We may elect to perform a qualitative assessment for the annual impairment test. If the qualitative assessment 
indicates it is more likely than not that the fair value of a reporting unit is less than its carrying amount, or if we elect not to 
perform a qualitative assessment, then we would be required to perform a quantitative test for goodwill impairment. The 
quantitative test is a two-step process consisting of comparing the carrying value of the reporting unit to an estimate of its 
fair value. If the estimated fair value of the reporting unit is less than the carrying value, goodwill is impaired and is written 
down to its estimated fair value. In 2016 and 2017, we elected to perform a qualitative assessment for our annual 
impairment test and concluded it is more likely than not our fair value was greater than its carrying amount; therefore, no 
further testing was required. 

The core deposit intangible that arose from the merger with Firstbank was initially measured at fair value and is being 
amortized into noninterest expense over a ten-year period using the sum-of-the-years-digits methodology. 

Repurchase Agreements: The Bank sells certain securities under agreements to repurchase. The agreements are treated as 
collateralized financing transactions, with the obligations to repurchase the securities sold reflected as liabilities and the 
securities underlying the agreements remaining in assets in the Consolidated Balance Sheets. 

Financial Instruments and Loan Commitments: Financial instruments include off-balance-sheet credit instruments, such as 
commitments to make loans and commercial letters of credit, issued to meet customer financing needs. The face amount for 
these items represents the exposure to loss, before considering customer collateral or ability to repay. Such financial 
instruments are recorded when they are funded. Instruments, such as standby letters of credit, that are considered financial 
guarantees are recorded at fair value. 

Stock-Based Compensation: Compensation cost for equity-based awards is measured on the grant date based on the fair 
value of the award at that date, and is recognized over the requisite service period, net of estimated forfeitures. Fair value of 
stock option awards is estimated using a closed option valuation (Black-Scholes) model. Fair value of restricted stock 
awards is based upon the quoted market price of the common stock on the date of grant. 

Advertising Costs: Advertising costs are expensed as incurred. 

Income Taxes: Income tax expense is the total of the current year income tax due or refundable, the change in deferred 
income tax assets and liabilities, and any adjustments related to unrecognized tax benefits. Deferred income tax assets and 
liabilities are recognized for the tax consequences of temporary differences between the carrying amounts and tax bases of 
assets and liabilities, computed using enacted tax rates applicable to future years. A valuation allowance, if needed, reduces 
deferred income tax assets to the amount expected to be realized. 

Fair Values of Financial Instruments: Fair values of financial instruments are estimated using relevant market information 
and other assumptions. Fair value estimates involve uncertainties and matters of significant judgment regarding interest 
rates, credit risk, prepayments and other factors, especially in the absence of broad markets for particular items. Changes in 
assumptions or in market conditions could significantly affect the estimates. The fair value estimates of existing on- and 
off-balance sheet financial instruments do not include the value of anticipated future business or the values of assets and 
liabilities not considered financial instruments.

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) 

Earnings Per Share: Basic earnings per share is based on the weighted average number of common shares and participating 
securities outstanding during the period. Diluted earnings per share include the dilutive effect of additional potential 
common shares issuable under our stock-based compensation plans using the treasury stock method. Our unvested stock 
awards, which contain non-forfeitable rights to dividends whether paid or unpaid (i.e., participating securities), are included 
in the number of shares outstanding for both basic and diluted earnings per share calculations. In the event of a net loss, our 
unvested stock awards are excluded from the calculations of both basic and diluted earnings per share. 

Comprehensive Income: Comprehensive income consists of net income and other comprehensive income (loss). Other 
comprehensive income (loss) includes unrealized gains and losses on securities available for sale and interest rate swaps 
which are also recognized as a separate component of equity. 

Derivatives: Derivative financial instruments are recognized as assets or liabilities at fair value. The accounting for changes 
in the fair value of derivatives depends on the use of the derivatives and whether the derivatives qualify for hedge 
accounting. Used as part of our asset and liability management to help manage interest rate risk, our derivatives have 
historically generally consisted of interest rate swap agreements that qualified for hedge accounting. We do not use 
derivatives for trading purposes. 

Changes in the fair value of derivatives that are designated, for accounting purposes, as a hedge of the variability of cash 
flows to be received on various assets and liabilities and are effective are reported in other comprehensive income. They are 
later reclassified into earnings in the same periods during which the hedged transaction affects earnings and are included in 
the line item in which the hedged cash flows are recorded. If hedge accounting does not apply, changes in the fair value of 
derivatives are recognized immediately in current earnings as interest income or expense. 

If designated as a hedge, we formally document the relationship between the derivative instrument and the hedged item, as 
well as the risk-management objective and the strategy for undertaking the hedge transaction. This documentation includes 
linking cash flow hedges to specific assets on the balance sheet. If designated as a hedge, we also formally assess, both at 
the hedge’s inception and on an ongoing basis, whether the derivative instrument that is used is highly effective in 
offsetting changes in cash flows of the hedged items. Ineffective hedge gains and losses are recognized immediately in 
current earnings as noninterest income or expense. We discontinue hedge accounting when we determine the derivative is 
no longer effective in offsetting changes in the cash flows of the hedged item, the derivative is settled or terminates, or 
treatment of the derivatives as a hedge is no longer appropriate or intended. 

 Contingencies: Loss contingencies, including claims and legal actions arising in the ordinary course of business, are 
recorded as liabilities when the likelihood of loss is probable and an amount or range of loss can be reasonably estimated. 
We do not believe there are any such matters outstanding that would have a material effect on the financial statements. 

Reclassifications: Certain items in the prior years’ financial statements have been reclassified to conform to the current year 
presentation.

Accounting Standards Updates: In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers. 
This ASU establishes a comprehensive revenue recognition standard for virtually all industries under U.S. GAAP, 
including those that previously followed industry-specific guidance such as the real estate, construction and software 
industries. The revenue standard’s core principle is built on the contract between a vendor and a customer for the provision 
of goods and services. It attempts to depict the exchange of rights and obligations between the parties in the pattern of 
revenue recognition based on the consideration to which the vendor is entitled. To accomplish this objective, the standard 
requires five basic steps: (i) identify the contract with the customer, (ii) identify the performance obligations in the contract, 
(iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations in the contract, and (v) 
recognize revenue when (or as) the entity satisfies a performance obligation. This ASU was originally effective for annual 
and interim periods beginning after December 15, 2016, with three transition methods available – full retrospective, 
retrospective and cumulative effect approach. In August 2015, the FASB issued ASU 2015-14, Revenue from Contracts 
with Customers – Deferral of Effective Date, which delays the implementation of this guidance by one year. Since the 
guidance does not apply to revenue associated with financial instruments, including loans and securities that are accounted 
for under GAAP, the new guidance will not have an impact on interest income.  We have completed an overall assessment 
of revenue streams and reviewed the related contracts potentially affected by the ASU.  We will adopt this ASU on January 
1, 2018 utilizing the modified retrospective approach with a cumulative effect adjustment to opening retained earnings.  We 
have determined that this ASU will not have a material effect on our financial position or results of operations.  Expanded 
disclosure requirements will be included in the March 31, 2018 Form 10-Q. 

In January 2016, the FASB issued ASU 2016-1, Recognition and Measurement of Financial Assets and Financial 
Liabilities. This ASU requires an entity to (i) measure equity investments at fair value through net income, with certain 
exceptions; (ii) present in OCI the changes in instrument-specific credit risk for financial liabilities measured using the fair 
value option; (iii) present financial assets and financial liabilities by measurement category and form of financial asset; (iv) 
calculate the fair value of financial instruments for disclosure purposes based on an exit price; and (v) assess a valuation 
allowance on deferred tax assets related to unrealized losses on available for sale debt securities in combination with other 
deferred tax assets. This ASU provides an election to subsequently measure certain nonmarketable equity investments at 
cost less any impairment and adjusted for certain observable price changes. This ASU also requires a qualitative 
impairment assessment of such equity investments and amends certain fair value disclosure requirements. The amendments 
are effective for public business entities for fiscal years, and interim periods within those fiscal years, beginning after 
December 15, 2017, and are not expected to have a material effect on our financial position or results of operations. 

In February 2016, the FASB issued ASU 2016-02, Leases. This ASU establishes a right-of-use (“ROU”) model that 
requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 
months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense 
recognition in the income statement. The ASU is effective for annual and interim periods beginning after December 15, 
2018. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or 
entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain 
practical expedients available. Adoption of this ASU is not expected to have a material effect on our financial position or 
results of operations.

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) 

In March 2016, the FASB issued ASU 2016-09, Compensation – Stock Compensation: Improvements to Employee Share-
Based Payment Accounting. This ASU requires that, prospectively, all tax effects related to share-based payments be made 
through the income statement at the time of settlement as opposed to excess tax benefits being recognized in additional 
paid-in capital under the current guidance. The ASU also removes the requirement to delay recognition of a tax benefit 
until it reduces current taxes payable. This change is required to be applied on a modified retrospective basis, with a 
cumulative-effect adjustment to opening retained earnings. Additionally, all tax related cash flows resulting from share-
based payments are to be reported as operating activities on the statement of cash flows, a change from the current 
requirement to present tax benefits as an inflow from financing activities and an outflow from operating activities. Finally, 
entities will be allowed to withhold an amount up to the employees’ maximum individual tax rate (as opposed to the 
minimum statutory tax rate) in the relevant jurisdiction without resulting in liability classification of the award. The change 
in withholding requirements will be applied on a modified retrospective approach. This standard will be effective for 
annual and interim periods beginning after December 15, 2016. Adoption of this ASU did not have a material effect on our 
financial position or results of operations. 

In June 2016, the FASB issued ASU No. 2016-13, Measurement of Credit Losses on Financial Instruments. This ASU 
significantly changes how entities will measure credit losses for most financial assets and certain other instruments that are 
not measured at fair value through net income. The standard will replace the current “incurred loss” approach with an 
“expected loss” model. The new model, referred to as the current expected credit loss (“CECL”) model, will apply to: (i) 
financial assets subject to credit losses and measured at amortized cost, and (ii) certain off-balance sheet credit exposures. 
This includes, but is not limited to, loans, leases, held-to-maturity securities, loan commitments and financial guarantees. 
The ASU also simplifies the accounting model for purchased credit-impaired debt securities and loans, and expands the 
disclosure requirements regarding an entity’s assumptions, models, and methods for estimating the allowance for loan and 
lease losses. In addition, entities will need to disclose the amortized cost balance for each class of financial asset by credit 
quality indicator, disaggregated by the year of origination. This ASU is effective for interim and annual reporting periods 
beginning after December 15, 2019, and early adoption is permitted for interim and annual reporting periods beginning 
after December 15, 2018. Entities will apply the standard’s provisions as a cumulative-effect adjustment to retained 
earnings as of the beginning of the first reporting period in which the guidance is effective (i.e., modified retrospective 
approach). We are currently evaluating the provisions of this ASU to determine the potential impact the new standard will 
have on our consolidated financial statements.  We are also in the process of selecting a software vendor for applying this 
new ASU, which we plan to implement later in 2018. 

In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash 
Receipts and Cash Payments.  This ASU will make eight targeted changes to how cash receipts and cash payments are 
presented and classified in the statement of cash flows and is effective for fiscal years beginning after December 15, 2017.  
The new standard will require adoption on a retrospective basis unless it is impractical to apply, in which case it would be 
required to apply the amendments prospectively as of the earliest date practicable.  We are currently evaluating the 
provisions of this ASU to determine the potential impact the new standard will have on our consolidated financial 
statements.   

In January 2017, the FASB issued ASU No. 2017-04, Goodwill and Other (Topic 350): Simplifying the Test for Goodwill 
impairment.  This ASU simplifies the subsequent measurement of goodwill by eliminating Step 2 from the goodwill 
impairment test.  Under this ASU, an entity should perform the Step 1 annual, or interim, goodwill impairment test by 
comparing the fair value of a reporting unit with its carrying value.  If the carrying amount exceeds the fair value, an entity 
should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair 
value, not to exceed the total amount of goodwill allocated to that reporting unit.  An entity still has the option to perform 
the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary.  This ASU is 
effective January 1, 2020 and early adoption is permitted.  The ASU should be applied prospectively.  We adopted this 
guidance on January 1, 2017.  The adoption of this guidance had no material impact on our financial position, results of 
operations or cash flows.

In March 2017, the FASB issued ASU No. 2017-08, Premium Amortization on Purchased Callable Debt Securities.  This 
ASU requires the premium to be amortized to the earliest call date.  The amendments do not require an accounting change 
for securities held at a discount; the discount continues to be amortized to maturity.  Previously, entities were allowed to 
amortize to contractual maturity or to call date.  This ASU is effective for annual reporting periods beginning after 
December 15, 2018, and early adoption is permitted.  The provisions of this ASU will not have an impact on our financial 
position or results of operations as we have always amortized premiums to the earliest call date. 

In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to 
Accounting for Hedging Activities.  The ASU changes the recognition and presentation requirements of hedge accounting, 
including eliminating the requirement to separately measure and report hedge ineffectiveness and presenting all items that 
affect earnings in the same income statement line as the hedged item.  The ASU also eases certain documentation and 
assessment requirements and modifies the accounting components excluded from the assessment of hedge effectiveness.  
This ASU is effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years.  
Early adoption is permitted.  We are currently evaluating the provisions of this ASU to determine the potential impact the 
new standard will have on our consolidated financial statements. 

In February 2018, the FASB issued ASU 2018-02, Reclassification of Certain Tax Effects from Accumulated Other 
Comprehensive Income.  This ASU requires reclassification from accumulated other comprehensive income to retained 
earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act.  The amount of the reclassification is the 
difference between the historical 35% corporate income tax rate and the newly enacted 21% corporate income tax rate.  
Because the amendments only relate to the reclassification of the income tax effects of the Tax Cuts and Jobs Act, the 
underlying guidance that requires that the effect of a change in tax laws of rates be included in income from continuing 
operations is not affected.  This ASU is effective for fiscal years beginning after December 15, 2018.  Early adoption is 
permitted.  We early adopted this ASU, which resulted in the reclassification of $0.9 million from accumulated other 
comprehensive income to retained earnings at December 31, 2017. 

NOTE 2 – BUSINESS COMBINATION 

We completed the merger of Firstbank Corporation (“Firstbank”), a Michigan corporation with approximately $1.5 billion 
in total assets and 46 branch locations, into Mercantile Bank Corporation as of June 1, 2014 (“Merger Date”).  Each share 
of Firstbank’s common stock was converted into the right to receive one share of Mercantile common stock, resulting in 
Mercantile issuing 8,087,272 shares of its common stock.  The merger provided an expanded geographic footprint for the 
Company and increased the size of the balance sheet. 

The Firstbank transaction was accounted for using the acquisition method of accounting and accordingly, assets acquired, 
liabilities assumed and consideration exchanged were recorded at estimated fair value on the Merger Date.  Goodwill of 
$49.5 million was calculated as the purchase premium after adjusting for the fair value of net assets acquired and represents 
the value expected from the synergies created from combining the two banking organizations as well as the economies of 
scale expected from combining the operations of the two companies.  None of the goodwill is deductible for income tax 
purposes as the merger is accounted for as a tax-free exchange.  

In most instances, determining the fair value of the acquired assets and assumed liabilities required us to estimate cash 
flows expected to result from those assets and liabilities and to discount those cash flows at appropriate rates of interest. 
The most significant of those determinations relates to the valuation of acquired loans. For such loans, the excess of cash 
flows expected at acquisition over the estimated fair value is recognized as interest income over the remaining lives of the 
loans. The difference between contractually required payments at acquisition and the cash flows expected to be collected at 
acquisition reflects the impact of estimated credit losses and other factors, such as prepayments. In accordance with the 
applicable accounting guidance for business combinations, there was no carry-over of Firstbank’s previously established 
allowance for loan losses.

NOTE 2 – BUSINESS COMBINATION (Continued) 

The acquired loans were divided into loans with evidence of credit quality deterioration, which are accounted for under 
ASC 310-30 (“acquired impaired”), and loans that do not meet this criteria, which are accounted for under ASC 310-20 
(“acquired non-impaired”). In addition, the loans are further categorized into different loan pools based primarily on the 
type and purpose of the loan.

We evaluate securities for other-than-temporary impairment at least on a quarterly basis.  Consideration is given to the 
length of time and the extent to which the fair value has been less than cost, the financial condition and near-term prospects 
of the issuer, and the intent and ability we have to retain our investment in the issuer for a period of time sufficient to allow 
for any anticipated recovery in fair value.  For those debt securities whose fair value is less than their amortized cost basis, 
we also consider our intent to sell the security, whether it is more likely than not that we will be required to sell the security 
before recovery and if we do not expect to recover the entire amortized cost basis of the security.  In analyzing an issuer’s 
financial condition, we may consider whether the securities are issued by the federal government or its agencies, whether 
downgrades by bond rating agencies have occurred and the results of reviews of the issuer’s financial condition. 

At December 31, 2017, 325 debt securities and one mutual fund with fair values totaling $253 million had unrealized losses 
aggregating $7.6 million.  After we considered whether the securities were issued by the federal government or its agencies 
and whether downgrades by bond rating agencies had occurred, we determined that unrealized losses were due to changing 
interest rate environments.  As we do not intend to sell our debt securities before recovery of their cost basis and we believe 
it is more likely than not that we will not be required to sell our debt securities before recovery of the cost basis, no 
unrealized losses are deemed to be other-than-temporary.

The amortized cost and fair values of debt securities at December 31, 2017, by maturity, are shown in the following table. 
The contractual maturity is utilized for U.S. Government agency debt obligations and municipal bonds.  Expected 
maturities may differ from contractual maturities because borrowers may have the right to call or prepay obligations with or 
without call or prepayment penalties. Securities not due at a single maturity date, primarily mortgage-backed securities, are 
shown separately.  Weighted average yields are also reflected, with yields for municipal securities shown at their tax 
equivalent yield.

Mortgage-backed securities totaling $5.0 million were sold in 2017, resulting in a nominal net gain.  No mortgage-backed 
securities were sold in 2016 or 2015.  Municipal general obligation bonds totaling $2.6 million, $0.3 million and $1.5 
million were sold during 2017, 2016 and 2015, respectively, resulting in a nominal net gain/loss. 

Securities issued by the State of Michigan and all its political subdivisions had a combined amortized cost of $112 million 
and $109 million at December 31, 2017 and December 31, 2016, respectively, with estimated market values of $112 
million and $107 million at the respective dates.  Securities issued by all other states and their political subdivisions had a 
combined amortized cost of $12.9 million and $19.5 million at December 31, 2017 and December 31, 2016, with estimated 
market values of $13.0 million and $19.5 million, respectively.  Total securities of any other specific issuer, other than the 
U.S. Government and its agencies and the State of Michigan and all its political subdivisions, did not exceed 10% of 
shareholders’ equity. 

The carrying value of U.S. Government agency debt obligations and mortgage-backed securities that are pledged to secure 
repurchase agreements was $119 million and $132 million at December 31, 2017 and 2016, respectively.  Investments in 
FHLBI stock are restricted and may only be resold to, or redeemed by, the issuer. 

NOTE 4 – LOANS AND ALLOWANCE FOR LOAN LOSSES 

Loans originated for investment are stated at their principal amount outstanding adjusted for partial charge-offs, the 
allowance, and net deferred loan fees and costs. Interest income on loans is accrued over the term of the loans primarily 
using the simple interest method based on the principal balance outstanding. Interest is not accrued on loans where 
collectability is uncertain. Accrued interest is included in other assets in the Consolidated Balance Sheets. Loan origination 
fees and certain direct costs incurred to extend credit are deferred and amortized over the term of the loan or loan 
commitment period as an adjustment to the related loan yield.

NOTE 4 – LOANS AND ALLOWANCE FOR LOAN LOSSES (Continued) 

Acquired loans were recorded at estimated fair value at acquisition. The acquired loans were segregated between those 
considered to be performing (“acquired non-impaired loans”) and those with evidence of credit deterioration (“acquired 
impaired loans”). Acquired loans are considered impaired if there is evidence of credit deterioration and if it is probable, at 
acquisition, all contractually required payments will not be collected. Acquired loans restructured after acquisition are not 
considered or reported as troubled debt restructurings if the loans evidenced credit deterioration as of the Merger Date and 
are accounted for in pools.  

The fair value estimates for acquired loans are based on expected prepayments and the amount and timing of discounted 
expected principal, interest and other cash flows. Credit discounts representing the principal losses expected over the life of 
the loan are also a component of the initial fair value. In determining the Merger Date fair value of acquired impaired loans, 
and in subsequent accounting, we have generally aggregated acquired commercial and consumer loans into pools of loans 
with common risk characteristics. 

The difference between the fair value of an acquired non-impaired loan and contractual amounts due at acquisition is 
accreted into interest income over the estimated life of the loan. Contractually required payments represent the total 
undiscounted amount of all uncollected principal and interest payments. Acquired non-impaired loans are placed on 
nonaccrual status and reported as nonperforming or past due using the same criteria applied to the originated loan portfolio. 

The excess of an acquired impaired loan’s contractually required payments over the amount of its undiscounted cash flows 
expected to be collected is referred to as the non-accretable difference. The non-accretable difference, which is neither 
accreted into income nor recorded on the Consolidated Balance Sheets, reflects estimated future credit losses and 
uncollectable contractual interest expected to be incurred over the life of the acquired impaired loan. The excess cash flows 
expected to be collected over the carrying amount of the acquired loan is referred to as the accretable yield. This amount is 
accreted into interest income over the remaining life of the acquired loans or pools using the level yield method. The 
accretable yield is affected by changes in interest rate indices for variable rate loans, changes in prepayment speed 
assumptions and changes in expected principal and interest payments over the estimated lives of the acquired impaired 
loans. 

We evaluate quarterly the remaining contractually required payments receivable and estimate cash flows expected to be 
collected over the lives of the impaired loans. Contractually required payments receivable may increase or decrease for a 
variety of reasons, for example, when the contractual terms of the loan agreement are modified, when interest rates on 
variable rate loans change, or when principal and/or interest payments are received. Cash flows expected to be collected on 
acquired impaired loans are estimated by incorporating several key assumptions similar to the initial estimate of fair value. 
These key assumptions include probability of default, loss given default, and the amount of actual prepayments after 
acquisition. Prepayments affect the estimated lives of loans and could change the amount of interest income, and possibly 
principal, expected to be collected. In re-forecasting future estimated cash flows, credit loss expectations are adjusted as 
necessary. The adjustments are based, in part, on actual loss severities recognized for each loan type, as well as changes in 
the probability of default. For periods in which estimated cash flows are not re-forecasted, the prior reporting period’s 
estimated cash flows are adjusted to reflect the actual cash received and credit events that transpired during the current 
reporting period.

NOTE 4 – LOANS AND ALLOWANCE FOR LOAN LOSSES (Continued) 

Increases in expected cash flows of acquired impaired loans subsequent to acquisition are recognized prospectively through 
adjustments of the yield on the loans or pools over their remaining lives, while decreases in expected cash flows are 
recognized as impairment through a provision for loan losses and an increase in the allowance. 

Year-end loans disaggregated by class of loan within the loan portfolio segments were as follows:

(1)   Reductions primarily reflect the result of exit events, including loan payoffs and charge-offs. 

(2)  Cost recovery accounting occurs once a pool’s recorded investment is reduced to zero based on the outcome 

of the aggregated loan level activity at cash flow estimation.  Proceeds received on pools in recovery status 
are deemed as recovery income, and are recorded as interest income as payments are received, with accretion 
no longer being recognized. 

Concentrations within the loan portfolio were as follows at year-end:

Impaired loans for which no allocation of the allowance for loan losses has been made generally reflect situations whereby 
the loans have been charged-down to estimated collateral value.  Interest income recognized on accruing troubled debt 
restructurings totaled $0.4 million, $1.2 million and $2.4 million during 2017, 2016 and 2015, respectively.  Interest 
income recognized on nonaccrual loans totaled $0.5 million, less than $0.1 million, and $1.7 million during 2017, 2016 and 
2015, respectively, reflecting the collection of interest at the time of principal pay-off.  Lost interest income on nonaccrual 
loans totaled $0.3 million, $0.1 million and $0.3 million during 2017, 2016 and 2015, respectively.

NOTE 4 – LOANS AND ALLOWANCE FOR LOAN LOSSES (Continued) 

Credit Quality Indicators. We utilize a comprehensive grading system for our commercial loans. All commercial loans are 
graded on a ten grade rating system. The rating system utilizes standardized grade paradigms that analyze several critical 
factors such as cash flow, operating performance, financial condition, collateral, industry condition and management. All 
commercial loans are graded at inception and reviewed and, if appropriate, re-graded at various intervals thereafter. The 
risk assessment for retail loans is primarily based on the type of collateral. 

Loans by credit quality indicators were as follows as of December 31, 2017:

NOTE 4 – LOANS AND ALLOWANCE FOR LOAN LOSSES (Continued) 

All commercial loans are graded using the following number system: 

Grade 1.    Excellent credit rating that contain very little, if any, risk of loss. 

Grade 2.    Strong sources of repayment and have low repayment risk. 

Grade 3.    Good sources of repayment and have limited repayment risk. 

Grade 4.    Adequate sources of repayment and acceptable repayment risk; however, characteristics are present that 

render the credit more vulnerable to a negative event. 

Grade 5.    Marginally acceptable sources of repayment and exhibit defined weaknesses and negative characteristics. 

Grade 6.    Well defined weaknesses which may include negative current cash flow, high leverage, or operating losses. 

Generally, if the credit does not stabilize or if further deterioration is observed in the near term, the loan 
will likely be downgraded and placed on the Watch List (i.e., list of lending relationships that receive 
increased scrutiny and review by the Board of Directors and senior management). 

Grade 7.    Defined weaknesses or negative trends that merit close monitoring through Watch List status. 

Grade 8.    Inadequately protected by current sound net worth, paying capacity of the obligor, or pledged collateral, 
resulting in a distinct possibility of loss requiring close monitoring through Watch List status. 

Grade 9.    Vital weaknesses exist where collection of principal is highly questionable. 

Grade 10.  Considered uncollectable and of such little value that their continuance as an asset is not warranted. 

The primary risk elements with respect to commercial loans are the financial condition of the borrower, the sufficiency of 
collateral, and timeliness of scheduled payments. We have a policy of requesting and reviewing periodic financial 
statements from commercial loan customers and employ a disciplined and formalized review of the existence of collateral 
and its value. The primary risk element with respect to each residential real estate loan and consumer loan is the timeliness 
of scheduled payments. We have a reporting system that monitors past due loans and have adopted policies to pursue 
creditor’s rights in order to preserve our collateral position.

The negative loan recoveries reflected for acquired loans during 2016 resulted from reversals of prior period recoveries 
associated with certain purchased credit impaired loans that were subject to pre-acquisition charge-offs.  Post-acquisition 
payments received on these loans were previously reported as loan loss recoveries in prior periods; during 2016 these 
recoveries were reversed and reported as recovery income if associated with specifically reviewed purchase credit impaired 
loans or retained gains if associated with purchase credit impaired pooled loans.

In general, our policy dictates that a renewal or modification of an 8- or 9-rated commercial loan meets the criteria of a 
troubled debt restructuring, although we review and consider all renewed and modified loans as part of our troubled debt 
restructuring assessment procedures. Loan relationships rated 8 contain significant financial weaknesses, resulting in a 
distinct possibility of loss, while relationships rated 9 reflect vital financial weaknesses, resulting in a highly questionable 
ability on our part to collect principal; we believe borrowers warranting such ratings would have difficulty obtaining 
financing from other market participants. Thus, due to the lack of comparable market rates for loans with similar risk 
characteristics, we believe 8- or 9-rated loans renewed or modified were done so at below market rates. Loans that are 
identified as troubled debt restructurings are considered impaired and are individually evaluated for impairment when 
assessing these credits in our allowance for loan losses calculation.

We determined that no valuation allowance was necessary as of December 31, 2017 or December 31, 2016.  The estimated 
fair value of mortgage servicing rights was $8.4 million and $8.0 million as of December 31, 2017 and December 31, 2016, 
respectively.  The fair value of mortgage servicing rights is estimated using a valuation model that calculates the present 
value of estimated future net servicing cash flows, taking into consideration expected mortgage loan prepayment rates, 
discount rates, servicing costs and other economic factors, which are determined based on current market conditions.  
During 2017, fair value was determined using a discount rate of 7.50%, a weighted average constant prepayment rate of 
11.8%, depending on the stratification of the specific right, and a weighted average delinquency rate of 0.73%.  During 
2016, fair value was determined using a discount rate of 7.01%, a weighted average constant prepayment rate of 11.5%, 
depending on the stratification of the specific right, and a weighted average delinquency rate of 0.68%. 

The weighted average amortization period was 3.4 years and 3.6 years as of December 31, 2017 and December 31, 2016,

Securities sold under agreements to repurchase (“repurchase agreements”) generally have original maturities of less than 
one year. Repurchase agreements are treated as financings, and the obligations to repurchase securities sold are reflected as 
liabilities. Securities involved with the repurchase agreements are recorded as assets of our Bank and are held in 
safekeeping by a correspondent bank. Repurchase agreements are offered principally to certain large deposit customers. 
Repurchase agreements are secured by securities with an aggregate fair value equal to the aggregate outstanding balance.

NOTE 10 - FEDERAL HOME LOAN BANK ADVANCES 

Federal Home Loan Bank of Indianapolis (“FHLBI”) advances totaled $220 million at December 31, 2017, and were 
expected to mature at varying dates from May 2018 through April 2024, with fixed rates of interest from 1.04% to 2.39% 
and averaging 1.72%. FHLBI advances totaled $175 million at December 31, 2016, and were expected to mature at varying 
dates ranging from March 2017 through April 2023, with fixed rates of interest from 1.04% to 2.11% and averaging 1.48%. 

Each advance is payable at its maturity date, and is subject to a prepayment fee if paid prior to the maturity date. The 
advances are generally collateralized by a blanket lien on our residential mortgage loan portfolio. Our borrowing line of 
credit as of December 31, 2017 totaled $731 million, with availability of $511 million.

NOTE 11 - FEDERAL INCOME TAXES 

On December 22, 2017, H.R.1, commonly known as the Tax Cuts and Jobs Act (the “Act”) was signed into law. The Act 
reduced our corporate federal tax rate from 35% to 21% effective January 1, 2018 and changed certain other provisions.  As 
a result, we are required to re-measure our deferred tax assets and liabilities using the enacted rate at which we expect them 
to be recovered or settled. The effect of this re-measurement is recorded to income tax expense in the year the tax law is 
enacted.  For 2017, the re-measurement of our net deferred tax asset resulted in additional income tax expense of $1.3 
million.  Concurrent with the enactment of the Act, the SEC staff issued Staff Accounting Bulletin No. 118 (“SAB 118”), 
which allows companies to recognize the cumulative impact of the income tax effects triggered by the enactment of the Act 
over a period of up to twelve months in the reporting period in which the adjustment is identified.  We applied SAB 118 
effective December 22, 2017, and will continue to refine the measurement of the net deferred tax balance during the 
preparation of our 2017 tax return as additional guidance and information becomes available. 

The consolidated income tax expense is as follows:

NOTE 11 - FEDERAL INCOME TAXES (Continued) 

A valuation allowance related to deferred tax assets is required when it is considered more likely than not that all or part of 
the benefits related to such assets will not be realized. At December 31, 2017 and 2016, we carried a valuation allowance of 
$0.1 million and $0.2 million, respectively, against capital loss carryforwards generated by the disposal of certain capital 
investments acquired in our merger with Firstbank.  During 2017 and 2016, we reversed $0.0 million and $0.1 million, 
respectively, of the valuation allowance due to generation of capital gains during the year.  The remaining $0.1 million of 
capital loss carryforwards will expire at December 31, 2020 and we continue to carry a valuation allowance against the 
related deferred tax asset.  We believe the remainder of our deferred tax assets is more likely than not to be realized. 

We had no unrecognized tax benefits at any time during 2017 or 2016 and do not anticipate any significant increase in 
unrecognized tax benefits during 2018.  Should the accrual of any interest or penalties relative to unrecognized tax benefits 
be necessary, it is our policy to record such accruals in our income tax accounts; no such accruals existed at any time 
during 2017 or 2016.  Our U.S. federal income tax returns are no longer subject to examination for all years before 2014. 

NOTE 12 – STOCK-BASED COMPENSATION 

Stock-based compensation plans are used to provide directors and employees with an increased incentive to contribute to 
our long-term performance and growth, to align the interests of directors and employees with the interests of our 
shareholders through the opportunity for increased stock ownership and to attract and retain directors and employees.  
During 2014 and 2015, stock option and restricted stock grants were provided to certain employees through the Stock 
Incentive Plan of 2006.  During 2016 and 2017, restricted stock grants were provided to certain employees through the 
Stock Incentive Plan of 2016.  Stock option grants were also provided to certain employees during 2016 through the Stock 
Incentive Plan of 2016.  Stock grants were provided to directors as retainer payments during 2014 and 2015 through the 
Stock Incentive Plan of 2006, and during 2016 and 2017 through the Stock Incentive Plan of 2016.  The Stock Incentive 
Plan of 2006 expired on January 18, 2016, and was effectively replaced with the Stock Incentive Plan of 2016 that was 
approved by shareholders in May, 2016.   

Under the Stock Incentive Plan of 2006 and the Stock Incentive Plan of 2016, incentive awards may include, but are not 
limited to, stock options, restricted stock, stock appreciation rights and stock awards. Incentive awards that are stock 
options or stock appreciation rights are granted with an exercise price not less than the closing price of our common stock 
on the date of grant.  Price, vesting and expiration date parameters are determined by Mercantile’s Compensation 
Committee on a grant-by-grant basis.  No payments are required from employees for restricted stock awards.  The restricted 
stock awards granted during 2014, 2015, 2016 and 2017 fully vest after three years.  The stock options granted during 
2014, 2015 and 2016, which were at 110% of the market price on the date of grant, fully vest after two years and expire 
after seven years.  At year-end 2017, there were approximately 314,000 shares authorized for future incentive awards. 

In conjunction with the Firstbank merger, all of our outstanding restricted stock awards, which were scheduled to vest in 
full in November, 2014, became fully vested on June 1, 2014.  The unrecognized compensation cost related to restricted 
stock grants was $5.7 million as of December 31, 2017, which will be recognized as expense over the next three years. 

Also in conjunction with the Firstbank merger, we issued Mercantile stock options in replacement of all outstanding 
Firstbank stock option grants that had been previously issued to Firstbank employees under the Firstbank Corporation 
Stock Option and Restricted Stock Plan of 1997 and the Firstbank Corporation 2006 Stock Compensation Plan.  In general, 
stock option grants for 50 shares or less fully vested after one year from date of grant, while stock option grants for more 
than 50 shares vested over a five-year period at 20% of the grant per annum starting one year from date of grant.  The stock 
option grants expire ten years from date of grant.  There were approximately 282,200 Mercantile stock options issued as a 
result of the merger, with about 258,400 of the stock option grants fully vested and exercisable on the date of merger.  The 
remaining 23,800 stock option grants vested during 2015.

The fair value of each stock option award is estimated on the date of grant using a closed option valuation (Black-Scholes) 
model that uses the assumptions noted in the table below.  Expected volatilities are based on historical volatilities on our 
common stock.  Historical data is used to estimate stock option expense and post-vesting termination behavior.  The 
expected term of stock options granted is based on historical data and represents the period of time that stock options 
granted are expected to be outstanding, which takes into account that the stock options are not transferable.  The risk-free 
interest rate for the expected term of the stock option is based on the U.S. Treasury yield curve in effect at the time of the 
stock option grant. 

The fair value of stock options granted during 2016 and 2015 was determined using the following weighted-average 
assumptions as of the grant date.  No stock options were granted in 2017.

NOTE 14 – COMMITMENTS AND OFF-BALANCE-SHEET RISK  

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 and standby letters of credit. 
Loan 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.  Standby letters of credit are conditional commitments issued by our Bank to guarantee the 
performance of a customer to a third party.  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 amounts do not necessarily represent future cash requirements. 

These instruments involve, to varying degrees, elements of credit risk in excess of the amount recognized, if any, in the 
balance sheet.  Our maximum exposure to loan loss in the event of nonperformance by the other party to the financial 
instrument for commitments to extend credit and standby letters of credit is represented by the contractual notional amount 
of those instruments.  We use the same credit policies in making commitments and conditional obligations as we do for on-
balance sheet instruments.  Collateral, such as accounts receivable, securities, inventory, and property and equipment, is 
generally obtained based on management’s credit assessment of the borrower.  If required, estimated loss exposure 
resulting from these instruments is expensed and recorded as a liability.  There was no liability balance for these 
instruments as of December 31, 2017 and 2016. 

At year-end 2017 and 2016, the rates on existing off-balance sheet instruments were substantially equivalent to current 
market rates, considering the underlying credit standing of the counterparties. 

Our maximum exposure to credit losses for loan commitments and standby letters of credit outstanding at year-end was as 
follows: 

Commercial unused lines of credit 
Unused lines of credit secured by 1 – 4 family residential properties 
Credit card unused lines of credit 
Other consumer unused lines of credit

Commitments to make loans generally reflect our binding obligations to existing and prospective customers to extend 
credit, including line of credit facilities secured by accounts receivable and inventory, and term debt secured by either real 
estate or equipment.  In most instances, line of credit facilities are for a one-year term and are at a floating rate tied to the 
Wall Street Journal Prime Rate or the 30-Day Libor rate.  For term debt secured by real estate, customers are generally 
offered a floating rate tied to the Wall Street Journal Prime Rate or the 30-Day Libor rate, and a fixed rate currently ranging 
from 4.00% to 7.00%.  These credit facilities generally balloon within five years, with payments based on amortizations 
ranging from 10 to 20 years.  For term debt secured by non-real estate collateral, customers are generally offered a floating 
rate tied to the Wall Street Journal Prime Rate or the 30-Day Libor rate, and a fixed rate currently ranging from 4.00% to 
7.50%.  These credit facilities generally mature and fully amortize within three to seven years.

NOTE 14 – COMMITMENTS AND OFF-BALANCE-SHEET RISK (Continued) 

Certain of our commercial loan customers have entered into interest rate swap agreements directly with our correspondent 
banks.  To assist our commercial loan customers in these transactions, and to encourage our correspondent banks to enter 
into the interest rate swap transactions with minimal credit underwriting analyses on their part, we have entered into risk 
participation agreements with the correspondent banks whereby we agree to make payments to the correspondent banks 
owed by our commercial loan customers under the interest rate swap agreement in the event that our commercial loan 
customers do not make the payments.  We are not a party to the interest rate swap agreements under these arrangements.  
As of December 31, 2017, all such interest rate swap agreements had been terminated by our commercial loan customers.  
These risk participation agreements were considered financial guarantees in accordance with applicable accounting 
guidance and are therefore recorded as liabilities at fair value, generally equal to the fees collected at the time of their 
execution.  These liabilities were accreted into income during the terms of the interest rate swap agreements, generally 
ranging from an original term of four to fifteen years. 

The following instruments are considered financial guarantees under current accounting guidance. These instruments are 
carried at fair value.

Chicago to meet regulatory reserve and clearing requirements at December 31, 2017 and December 31, 2016, respectively. 

NOTE 15 – BENEFIT PLANS 

We have a 401(k) benefit plan that covers substantially all of our employees.  The percent of our matching contributions to 
the 401(k) benefit plan is determined annually by the Board of Directors.  The matching contribution has been 4.25% since 
January 1, 2014.   Matching contributions, if made, are immediately vested.  Our 2017, 2016 and 2015 matching 401(k) 
contributions charged to expense were $1.3 million, $1.2 million and $1.2 million, respectively.  Effective April 1, 2018, 
the matching contribution will be 5.00%. 

We have a deferred compensation plan in which all persons serving on the Board of Directors may defer all or portions of 
their annual retainer and meeting fees, with distributions to be paid upon termination of service as a director or specific 
dates selected by the director.  We also have a non-qualified deferred compensation program in which selected officers may 
defer all or portions of salary and bonus payments.  The deferred amounts, totaling $3.2 million and $3.4 million as of 
December 31, 2017 and 2016, respectively, are categorized as other liabilities in the Consolidated Balance Sheets, and are 
paid interest at a rate equal to the Wall Street Journal Prime Rate.  Interest expense was less than $0.1 million per year 
during the last three years.

NOTE 15 – BENEFIT PLANS (Continued) 

The Mercantile Bank Corporation Employee Stock Purchase Plan of 2014 is a non-compensatory plan intended to 
encourage full- and part-time employees of Mercantile and its subsidiaries to promote our best interests and to align 
employees’ interests with the interests of our shareholders by permitting employees to purchase shares of our common 
stock through regular payroll deductions.  Shares are purchased on the last business day of each calendar quarter at a price 
equal to the consolidated closing bid price of our common stock reported on The Nasdaq Stock Market.  A total of 250,000 
shares of common stock may be issued under the existing plan; however, the number of shares may be adjusted to reflect 
any stock dividends and other changes in our capitalization.  The number of shares issued totaled 1,351 and 1,362 in 2017 
and 2016, respectively. As of December 31, 2017, there were approximately 244,000 shares available under our current 
plan.  

NOTE 16 – HEDGING ACTIVITIES 

Our interest rate risk policy includes guidelines for measuring and monitoring interest rate risk.  Within these guidelines, 
parameters have been established for maximum fluctuations in net interest income.  Possible fluctuations are measured and 
monitored using net interest income simulation.  Our policy provides for the use of certain derivative instruments and 
hedging activities to aid in managing interest rate risk to within policy parameters. 

In February 2012, we entered into an interest rate swap agreement with a correspondent bank to hedge the floating rate on 
the subordinated debentures issued to Mercantile Bank Capital Trust I, which became effective in January 2013 and 
matured in January 2018.  The $32.0 million of subordinated debentures have a rate equal to the 90-Day Libor Rate plus a 
fixed spread of 218 basis points, and are subject to repricing quarterly.  The interest rate swap agreement provided for us to 
pay our correspondent bank a fixed rate, while our correspondent bank paid us the 90-Day Libor Rate on a $32.0 million 
notional amount.  The quarterly re-set dates for the floating rate on the interest rate swap agreement were the same as the 
re-set dates for the floating rate on the subordinated debentures.  The interest rate swap agreement was accounted for under 
hedge accounting guidelines; therefore, fluctuations in the fair value of the interest rate swap agreement, net of tax effect, 
were recorded in other comprehensive income.  As of December 31, 2017 and 2016, the fair value of the interest rate swap 
agreement was recorded as a liability in the amount of less than $0.1 million and $0.1 million, respectively. 

Effective January 26, 2016, the notional amount of the interest rate swap agreement was reduced from $32.0 million down 
to $21.0 million, reflecting the $11.0 million repurchase of the associated trust preferred securities on that date.  We 
recorded interest expense of approximately $154,000 in January 2016 as part of the transaction, in large part reflecting the 
market value of the interest rate swap on that date of the $11.0 million portion.

See Note 18 for a description of the fair value hierarchy as well as a disclosure of levels for classes of financial assets 
and liabilities. 
It is not practical to determine the fair value of FHLBI stock due to transferability restrictions. 

Carrying amount is the estimated fair value for cash and cash equivalents, FHLBI stock, accrued interest receivable and 
payable, demand deposits, securities sold under agreements to repurchase, and variable rate loans and deposits that reprice 
frequently and fully.  Security fair values are based on market prices or dealer quotes, and if no such information is 
available, on the rate and term of the security and information about the issuer.  For fixed rate loans and deposits and for 
variable rate loans and deposits with infrequent repricing or repricing limits, fair value is based on discounted cash flows 
using current market rates applied to the estimated life and credit risk.  The fair value of mortgage servicing rights is 
estimated using a valuation model that calculates the present value of estimated future net servicing cash flows, taking into 
consideration expected mortgage loan prepayment rates, discount rates, servicing costs and other economic factors, which 
are determined based on current market conditions.  Fair value of subordinated debentures and Federal Home Loan Bank 
advances is based on current rates for similar financing.  Fair value of the interest rate swap is determined primarily 
utilizing market-consensus forecasted yield curves.  Fair value of off-balance sheet items is estimated to be nominal.

NOTE 18 – FAIR VALUE MEASUREMENTS 

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly 
transaction between market participants. A fair value measurement assumes that the transaction to sell the asset or transfer 
the liability occurs in the principal market for the asset or liability, or in the absence of a principal market, the most 
advantageous market for the asset or liability.  The price of the principal (or most advantageous) market used to measure 
the fair value of the asset or liability is not adjusted for transaction costs.  An orderly transaction is a transaction that 
assumes exposure to the market for a period prior to the measurement date to allow for marketing activities that are usual 
and customary for transactions involving such assets and liabilities; it is not a forced transaction.  Market participants are 
buyers and sellers in the principal market that are (i) independent, (ii) knowledgeable, (iii) able to transact and (iv) willing 
to transact. 

We are required to use valuation techniques that are consistent with the market approach, the income approach and/or the 
cost approach.  The market approach uses prices and other relevant information generated by market transactions involving 
identical or comparable assets and liabilities.  The income approach uses valuation techniques to convert future amounts, 
such as cash flows or earnings, to a single present amount on a discounted basis.  The cost approach is based on the amount 
that currently would be required to replace the service capacity of an asset (replacement cost).  Valuation techniques should 
be consistently applied.  Inputs to valuation techniques refer to the assumptions that market participants would use in 
pricing the asset or liability.  Inputs may be observable, meaning those that reflect the assumptions market participants 
would use in pricing the asset or liability developed based on market data obtained from independent sources, or 
unobservable, meaning those that reflect our own estimates about the assumptions market participants would use in pricing 
the asset or liability based on the best information available in the circumstances.  In that regard, we utilize a fair value 
hierarchy for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets or 
liabilities and the lowest priority to unobservable inputs.  The fair value hierarchy is as follows: 

Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets that we have the ability to access as 
of the measurement date. 

Level 2: Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities in 
active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; or other inputs that 
are observable or can be derived from or corroborated by observable market data by correlation or other means. 

Level 3: Significant unobservable inputs that reflect our own estimates about the assumptions that market participants 
would use in pricing an asset or liability. 

The following is a description of our valuation methodologies used to measure and disclose the fair values of our financial 
assets and liabilities on a recurring or nonrecurring basis: 

Securities available for sale. Securities available for sale are recorded at fair value on a recurring basis.  Fair value 
measurement is based on quoted prices, if available. If quoted prices are not available, fair values are measured using 
independent pricing models.  Level 2 securities include U.S. Government agency debt obligations, mortgage-backed 
securities issued or guaranteed by U.S. Government agencies, municipal general obligation and revenue bonds, and mutual 
funds.  Level 3 securities include bonds issued by certain relatively small municipalities located within our markets that 
have very limited marketability due to their size and lack of ratings from a recognized rating service.  We carry these bonds 
at historical cost, which we believe approximates fair value, unless our periodic financial analysis or other information 
becomes known which necessitates an impairment.  There was no such impairment as of December 31, 2017 or 2016.  We 
have no Level 1 securities available for sale.

NOTE 18 – FAIR VALUE MEASUREMENTS (Continued) 

Mortgage loans held for sale.  Mortgage loans held for sale are carried at the lower of aggregate cost or fair value and are 
measured on a nonrecurring basis.  Fair value is based on independent quoted market prices, where applicable, or the prices 
for other mortgage whole loans with similar characteristics.  As of December 31, 2017 and 2016, we determined that the 
fair value of our mortgage loans held for sale approximated the recorded cost of $2.6 million and $1.0 million, respectively. 

Loans.  We do not record loans at fair value on a recurring basis.  However, from time to time, we record nonrecurring fair 
value adjustments to collateral dependent loans to reflect partial write-downs or specific reserves that are based on the 
observable market price or current estimated value of the collateral.  These loans are reported in the nonrecurring table 
below at initial recognition of impairment and on an ongoing basis until recovery or charge-off.  The fair values of 
impaired loans are determined using either the sales comparison approach or income approach; respective unobservable 
inputs for the approaches consist of adjustments for differences between comparable sales and the utilization of appropriate 
capitalization rates. 

Foreclosed assets.  At time of foreclosure or repossession, foreclosed and repossessed assets are adjusted to fair value less 
costs to sell upon transfer of the loans to foreclosed and repossessed assets, establishing a new cost basis.  We subsequently 
adjust estimated fair value on foreclosed assets on a nonrecurring basis to reflect write-downs based on revised fair value 
estimates.  The fair values of parcels of other real estate owned are determined using either the sales comparison approach 
or income approach; respective unobservable inputs for the approaches consist of adjustments for differences between 
comparable sales and the utilization of appropriate capitalization rates. 

Derivatives.  The interest rate swap agreement is measured at fair value on a recurring basis.  We measure fair value 
utilizing models that use primarily market observable inputs, such as forecasted yield curves, and accordingly, the interest 
rate swap agreement is classified as Level 2.

The carrying values are based on the estimated value of the property or other assets.  Fair value estimates of collateral on 
impaired loans and foreclosed assets are reviewed periodically.  Our credit policies establish criteria for obtaining 
appraisals and determining internal value estimates.  We may also adjust outside appraisals and internal evaluations based 
on identifiable trends within our markets, such as sales of similar properties or assets, listing prices and offers received.  In 
addition, we may discount certain appraised and internal value estimates to address current distressed market conditions.  
For real estate dependent loans and foreclosed assets, we generally assign a 15% to 25% discount factor for commercial-
related properties, and a 25% to 50% discount factor for residential-related properties.  In a vast majority of cases, we 
assign a 10% discount factor for estimated selling costs.

NOTE 20 – SUBORDINATED DEBENTURES 

We have five business trusts that are wholly-owned subsidiaries of Mercantile, four of which were assumed by Mercantile 
in conjunction with the Firstbank merger.  A fair value discount of $15.0 million was recorded at the time of the merger, 
which is being amortized at $0.7 million annually over the following 21.5 years.  Each of the trusts was formed to issue 
Preferred Securities that were sold in private sales, as well as selling Common Securities to Mercantile.  The proceeds from 
the Preferred and Common Securities sales were used by the trusts to purchase Floating Rate Notes issued by Mercantile. 
The rates of interest, interest payment dates, call features and maturity dates of each Floating Rate Note are identical to its 
respective Preferred Securities.  The net proceeds from the issuance of the Floating Rate Notes were used for a variety of 
purposes, including contributions to the Bank as capital to provide support for asset growth and the funding of stock 
repurchase programs and certain acquisitions. 

The only significant assets of our trusts are the Floating Rate Notes, and the only significant liabilities of our trusts are the 
Preferred Securities.  The Floating Rate Notes are categorized on our Consolidated Balance Sheets as subordinated 
debentures and the interest expense is recorded on our Consolidated Statements of Income under interest expense on other 
borrowings. 

On January 26, 2016, we closed on a repurchase of trust preferred securities that were auctioned as part of a pooled 
collateralized debt obligation (“Fund”).  The Fund owned $11.0 million of the $32.0 million in trust preferred securities 
that had been issued by Mercantile Bank Capital Trust I.  The $11.0 million in trust preferred securities was retired upon 
the repurchase, resulting in a commensurate reduction in the related Floating Rate Junior Subordinate Note, leaving $21.0 
million outstanding.

NOTE 21 - REGULATORY MATTERS 

We are subject to regulatory capital requirements administered by federal banking agencies.  Capital adequacy guidelines 
and prompt corrective action regulations involve quantitative measures of assets, liabilities, and certain off-balance sheet 
items calculated under regulatory accounting practices.  Capital amounts and classifications are also subject to qualitative 
judgments by regulators about components, risk weightings, and other factors, and the regulators can lower classifications 
in certain cases.  Failure to meet various capital requirements can initiate regulatory action that could have a direct material 
effect on the financial statements.

NOTE 21 - REGULATORY MATTERS (Continued) 

The prompt corrective action regulations provide five classifications, including well capitalized, adequately capitalized, 
undercapitalized, significantly undercapitalized, and critically undercapitalized, although these terms are not used to 
represent overall financial condition.  If an institution is not well capitalized, regulatory approval is required to accept 
brokered deposits. Subject to limited exceptions, no institution may make a capital distribution if, after making the 
distribution, it would be undercapitalized.  If an institution is undercapitalized, it is subject to close monitoring by its 
principal federal regulator, its asset growth and expansion are restricted, and plans for capital restoration are required.  In 
addition, further specific types of restrictions may be imposed on the institution at the discretion of the federal regulator.  
At year-end 2017 and 2016, our Bank was in the well capitalized category under the regulatory framework for prompt 
corrective action.  There are no conditions or events since December 31, 2017 that we believe have changed our Bank’s 
categorization.

Under the final Basel III capital rules that became effective on January 1, 2015, there is a requirement for a common equity 
Tier 1 capital conservation buffer of 2.5% of risk-weighted assets which is in addition to the other minimum risk-based 
capital standards in the rule.  Institutions that do not meet this required capital buffer will become subject to progressively 
more stringent limitations on the percentage of earnings that can be paid out in cash dividends or used for stock repurchases 
and on the payment of discretionary bonuses to senior executive management.  The capital buffer requirement is being 
phased in over three years beginning in 2016.  The capital buffer requirement effectively raises the minimum required 
common equity Tier 1 capital ratio to 7.0%, the Tier 1 capital ratio to 8.5% and the total capital ratio to 10.5% on a fully 
phased-in basis on January 1, 2019.  We believe that, as of December 31, 2017, our bank would meet all capital adequacy 
requirements under the Basel III capital rules on a fully phased-in basis as if all such requirements were currently in effect. 

Federal and state banking laws and regulations place certain restrictions on the amount of dividends our Bank can transfer 
to Mercantile and on the capital levels that must be maintained.  At year-end 2017, under the most restrictive of these 
regulations, our Bank could distribute approximately $42.6 million to Mercantile as dividends without prior regulatory 
approval.  Our and our bank’s ability to pay cash and stock dividends is subject to limitations under various laws and 
regulations and to prudent and sound banking practices.  On January 12, 2017, our Board of Directors declared a cash 
dividend on our common stock in the amount of $0.18 per share that was paid on March 22, 2017 to shareholders of record 
as of March 10, 2017.  On April 13, 2017, our Board of Directors declared a cash dividend on our common stock in the 
amount of $0.18 per share that was paid on June 21, 2017 to shareholders of record as of June 9, 2017.  On July 13, 2017, 
our Board of Directors declared a cash dividend on our common stock in the amount of $0.19 per share that was paid on 
September 20, 2017 to shareholders of record as of September 8, 2017.  On October 12, 2017, our Board of Directors 
declared a cash dividend on our common stock in the amount of $0.19 per share that was paid on December 20, 2017 to 
shareholders of record as of December 8, 2017.

MERCANTILE BANK CORPORATION 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 
December 31, 2017 

NOTE 21 - REGULATORY MATTERS (Continued) 

On January 11, 2018, our Board of Directors declared a cash dividend on our common stock in the amount of $0.22 per 
share that will be paid on March 21, 2018 to shareholders of record as of March 9, 2018.  

On January 30, 2015, we announced that our Board of Directors had authorized a new program to repurchase up to $20.0 
million of our common stock from time to time in open market transactions at prevailing market prices or by other means 
in accordance with applicable regulations.  On April 19, 2016, we announced a $15.0 million expansion of the stock 
repurchase plan.  Since inception, we have purchased a total of 956,419 shares at a total price of $19.5 million, at an 
average price per share of $20.38; no shares were purchased under the authorized plan during 2017.  The stock buybacks 
have been funded from cash dividends paid to us from our Bank.  Additional repurchases may be made in future periods 
under the authorized plan, which would also likely be funded from cash dividends paid to us from our Bank. 

Our consolidated capital levels as of December 31, 2017 and 2016 include $43.4 million and $42.8 million, respectively, of 
trust preferred securities subject to certain limitations.  Under applicable Federal Reserve guidelines, the trust preferred 
securities constitute a restricted core capital element.  The guidelines provide that the aggregate amount of restricted core 
elements that may be included in Tier 1 capital must not exceed 25% of the sum of all core capital elements, including 
restricted core capital elements, net of goodwill less any associated deferred tax liability.  Our ability to include the trust 
preferred securities in Tier 1 capital in accordance with the guidelines is not affected by the provision of the Dodd-Frank 
Act generally restricting such treatment, because (i) the trust preferred securities were issued before May 19, 2010, and (ii) 
our total consolidated assets as of December 31, 2009 were less than $15.0 billion.  At December 31, 2017 and 2016, all 
$43.4 million and $42.8 million, respectively, of the trust preferred securities were included as Tier 1 capital of Mercantile.  

NOTE 22 – ACCUMULATED OTHER COMPREHENSIVE INCOME (LOSS) 

At December 31, 2017, accumulated other comprehensive income, net of tax effects (as applicable), consisted of a net 
unrealized loss on available for sale securities of $4.9 million and the fair value of an interest rate swap of less than 
negative $0.1 million. At December 31, 2016, accumulated other comprehensive income, net of tax effects (as applicable), 
consisted of a net unrealized loss on available for sale securities of $5.5 million and the fair value of an interest rate swap of 
negative $0.1 million. At December 31, 2015, accumulated other comprehensive income, net of tax effects (as applicable), 
consisted of a net unrealized gain on available for sale securities of $1.4 million and the fair value of an interest rate swap 
of negative $0.2 million.
