We all have a story to tell.

At Mercantile Bank, our stories revolve around

our customers and the communities we serve:

The new mother whose day we brightened with 

a simple courtesy. The business owner whose

future we changed with a word of advice.

The children whose lives we enriched with 

an investment of time and attention.

These are the tales we tell each other over

coffee breaks and lunches, while sharing a ride 

to work or pitching in on a charity project.

Individually, these stories reflect the character of

the people who work at Mercantile. Collectively,

they illustrate the service commitment that has

2006 was another excellent year for the 

Corporation and its shareholders.

Reaching $2 Billion In Assets

In September, 2006, Mercantile Bank reached another notable 

milestone, as we surpassed $2 billion in assets. This was 

accomplished in little more than three years after passing the 

$1 billion mark – another extraordinary achievement. 

Less than a decade ago, the founders of Mercantile Bank were

sitting around a kitchen table, strategizing ways to position our

soon-to-debut enterprise against the larger banks that dominated the

West Michigan landscape. Today, we are one of those “larger” banks. 

In fact, as of June 30, 2006, we ranked 292nd in assets out 

of more than 7,700 banks nationwide. That puts us in the top 

4% of all banks across the country.

Closer to home, we ranked as the 9th largest Michigan-based

bank in the state. This was also as of June 30, 2006, in a universe of 

173 state-based financial institutions.

Our market status is even more impressive locally. We are now

number two in market share in the Grand Rapids Metropolitan

Statistical Area. We’ve attained this significant market position in

less than 10 years, with just 8 locations – 6 in West Michigan.

Back to School

partnered with an inner-city school,

Moores Park Elementary, to help 

teach kids the importance of saving

and budgeting. The entire Mercantile

This significant growth is a direct result of the decisions made

around that kitchen table in 1997. We determined that we would

focus on business banking, limit brick-and-mortar expenses, and

and deliver superior returns to our shareholders.

Obviously, we’ve been proven right. Now, as we enter our 

10th year of operation, we are renewing the commitments we 

made at the beginning of our journey – most especially, our pledge

to provide the very best service possible.

“The teachers love it,” says 

Cassy Puskala. “They’re using it 

to help teach counting and math 

to the kids, who range from 

kindergartners to third graders.”

I Can Do That

have much authority in my position,”

says Cesar Gonzales. “But at

Mercantile, we’re all empowered 

to make decisions on the spot.”

Growing Big, Acting Small

We’ve all seen it: the business with an uncanny ability to satisfy 

customers grows larger and larger – and, in the process, seems to

lose touch with its customers and their needs.

This unfortunate scenario has become so prevalent in

American business that our own customers and shareholders have

joined financial analysts and journalists in raising it as a concern.

How, they ask, will Mercantile retain its service culture as it grows

larger and more geographically diverse?

The answer lies in the stories of the Mercantile associates 

featured in these pages, and in many other stories we could print if

we had the space. Yes, Mercantile is quickly becoming a “big” bank.

But we still think and act as if we were an entrepreneurial upstart,

striving to win the attention and loyalty of every single customer.

We empower our front-line associates to make the kinds of

decisions other banks reserve only for supervisors. We support our

lenders in exploring every possible avenue to make a deal work. 

We encourage each other to volunteer time and talents to improve

Cesar immediately waived the 

overdraft fee on a check. “Then she

wanted to wait while I got approval

from a manager,” Cesar grins.

“It took me awhile to convince 

her I could do it myself!”

We’re able to maintain this entrepreneurial zeal because of 

the measured and deliberate nature of our expansion. While other

banks seek to accelerate growth by building an extensive branch

network, we’ve chosen to minimize our physical infrastructure 

and build greater efficiencies into our rather non-traditional 

banking model.

insight and ambition.

This is just one more vindication of our original vision 

for Mercantile … and one more reason Mercantile will be able to

continue “acting small” no matter how large we grow.

New Challenges Emerge

The kind of growth we’ve achieved does not go unnoticed. 

One very positive consequence is the attention of a broadening 

range of shareholders. One not-so-positive (but entirely expected)

consequence is greater attention from our competitors.

Competitive pressures were one of our main challenges in

2006. Local and regional banks continued to bid aggressively on

The other key challenge we faced in 2006 was not unique 

a much larger bank – including a

sophisticated payroll processing 

system. But all the technology in 

the world can’t force customers 

Mike Kroft
eBanking Services Manager
Grand Rapids

to get their payroll file to us on time

every week.

“We don’t say, well, you’re out 

of luck because you missed our

deadline,” Mike Kroft relates.

“We work to make it happen, even 

if it means staying late or getting 

in early. We’ll manually create files 

to Mercantile. The entire banking industry has been, and is, 

contending with interest rate uncertainty and a somewhat unusual

“inversion” of the normal relationship between short- and 

long-term interest rates. Under this interest rate scenario, short-term

rates have been higher than long-term rates. This makes it much

more difficult for most banks to maintain their margins – that is,

the difference in interest earned on loans and investments and 

interest paid on deposits and other indebtedness.

Even with increasing competitive pressures and interest 

rate challenges, even though we are operating in an economy that

generally lags behind the rest of the nation, we are pleased to 

report that our strategy remains a winning one:

Mercantile Bank once again grew earnings and assets 

at double-digit rates in 2006.

Total revenue, comprised of net interest income and

Non-interest income for the year was $5.3 million, 

compared with $5.7 million for 2005. However, approximately

$0.7 million of the 2005 fee income represented a one-time gain on

the fourth-quarter 2005 sale of state tax credits derived from the

construction of our new headquarters building. Subtracting this

gain from the equation results in a year-to-year gain in fee income.

expense at a relatively stable level throughout the year.

For 2006, our efficiency ratio (the cost of generating $1.00 

of net revenue – so lower is better) averaged 48.3%, compared to

51.1% in 2005. This ratio was below 50% for each of the four

quarters of 2006. Non-interest expense was $32.3 million for 2006,

a modest increase of 3.7% over fiscal year 2005; this compares with

a year-over-year asset growth of 12.5%. Salaries and benefits, the

largest component of non-interest expense, was $19.0 million, an

increase of 1.9% over the prior year.

While asset quality remained relatively stable throughout the

year, net loan charge-offs for 2006 were $4.9 million, equivalent to

0.29% of average loans. This compares to $1.1 million or 0.08% of

average loans for the prior year. Non-performing assets were $9.6

million, or 0.46% of total assets at December 31, 2006, compared

with $4.0 million, or 0.22% of total assets, at December 31, 2005.

These figures are historically high for Mercantile, but they

still compare favorably with what is happening both nationally and

for each other – we never have

Bank Corporation paid an annual cash dividend of $0.51 per share

dividend increase of $0.08 per share, or 18.6%.

A New Chapter Begins

Although 2006 was an extremely challenging year, we 

affirmed our ability to provide superior results in a difficult 

operating environment.

We dealt very efficiently and effectively with the numerous

challenges we faced, and we positioned the bank for another 

competitive year in 2007. 

Highlights of the coming year will include the completion 

of construction on our new Lansing office. Our associates and 

customers are looking forward to the move from our current 

space to this larger, more user-friendly building. The office is 

slated for a spring grand opening. 

We are also currently in the process of introducing our 

next-generation Internet banking platform. Cutting-edge 

technology is an essential part of our business plan, as it makes

banking convenient to all, and lessens the need for new 

branch offices. Our new Internet product adds features and

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.   

Mercantile Bank Mortgage Company initiated business in October 2000 as a subsidiary of our bank, 
and was reorganized as Mercantile Bank Mortgage Company, LLC (“our mortgage company”), on January 1, 
2004.  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 new facility in downtown Grand Rapids which serves as our bank’s new main office and Mercantile 
Bank Corporation’s headquarters.  Mercantile Bank Capital Trust I (the “Mercantile trust”), a business trust 
subsidiary, was formed in September 2004 to issue trust preferred securities. 

To date we have raised capital from our initial public offering of common stock in October 1997, a 

public offering of common stock in July 1998, three private placements of common stock during 2001, a public 
offering of common stock in August 2001 and a public offering of common stock in September 2003.  In 
addition, we raised capital through a public offering of $16.0 million of trust preferred securities in 1999, which 
was refinanced as part of a $32.0 million private placement of trust preferred securities in 2004.  Our expenses 
have generally been paid using the proceeds of the capital sales and dividends from our bank.  Our principal 
source of future operating funds is expected to be dividends from our bank. 

We filed an election to become a financial holding company, pursuant to the Bank Holding Company 

Act, as amended by Title I of the Gramm-Leach-Bliley Act and implementing Federal Reserve Board 
regulations, which election became effective March 23, 2000. 

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 Office of Financial and Insurance Services.  Our bank’s deposits are insured to 
the maximum extent permitted by law by the Federal Deposit Insurance Corporation (“FDIC”).  Our bank’s 
primary service area is the Kent and Ottawa County areas of West Michigan, which includes the City of Grand 
Rapids, the second largest city in the State of Michigan.  In addition, our bank opened new offices in the cities 
of East Lansing and Ann Arbor, Michigan, during 2005. 

Our bank, through its eight offices, provides commercial and retail banking services primarily to 

small- to medium-sized businesses based in and around the Grand Rapids, Holland, Lansing and Ann Arbor 
metropolitan areas.  These offices consist of a main office located at 310 Leonard Street NW, Grand Rapids, 
Michigan, a combination branch and retail loan center located at 4613 Alpine Avenue NW, Comstock Park, 
Michigan, a combination branch and operations center located at 5610 Byron Center Avenue SW, Wyoming, 
Michigan, and branches located at 4860 Broadmoor Avenue SE, Kentwood, Michigan, 3156 Knapp Street NE, 
Grand Rapids, Michigan, 880 East 16th Street, Holland, Michigan, 1651 West Lake Lansing Road, East 
Lansing, Michigan, and 325 Eisenhower Parkway, Ann Arbor, Michigan.

Our bank makes secured and unsecured commercial, construction, mortgage and consumer loans, and 
accepts checking, savings and time deposits.  Our bank owns six automated teller machines ("ATM"), located 
at our branch locations in Grand Rapids and Holland, that participate in the MAC, NYCE 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 telephone and personal computer.  Courier service is provided 
to certain commercial customers, and safe deposit facilities are available at our branch locations in Grand 
Rapids and Holland.  Our bank does not have trust powers.  In December 2001, our bank entered into a joint 
brokerage services and marketing agreement with Raymond James Financial Services, Inc. to make available to 
its customers financial planning, retail brokerage, equity research, insurance and annuities, retirement planning, 
trust services and estate planning. 

Our Mortgage Company 

Our mortgage company’s predecessor, Mercantile Bank Mortgage Company, commenced operations 

on October 24, 2000, when our bank contributed most of its residential mortgage loan portfolio and 
participation interests in certain commercial mortgage loans to Mercantile Bank Mortgage Company.  On the 
same date, our bank also transferred its residential mortgage origination function to Mercantile Bank Mortgage 
Company.  On January 1, 2004, Mercantile Bank Mortgage Company was reorganized as Mercantile Bank 
Mortgage Company, LLC, a limited liability company, which is 99% owned by our bank and 1% owned by our 
insurance company.  The reorganization had no impact on the company’s financial position or results of 
operations.  Mortgage loans originated and held by our mortgage company are serviced by our bank pursuant to 
a servicing agreement.   

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.   

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. 

The Mercantile Trust 

In 2004, we formed the Mercantile trust, a Delaware business trust.  Mercantile trust’s business and 

affairs are conducted by its property trustee, a Delaware trust company, and three individual administrative 
trustees who are employees and officers of the company.  Mercantile trust was established for the purpose of 
issuing and selling its Series A and Series B trust preferred securities and common securities, and used the 
proceeds from the sales of those securities to acquire Series A and Series B Floating Rate Notes issued by the 
company.  Substantially all of the net proceeds received by the company from the Series A transaction were 
used to redeem the trust preferred securities that had been issued by MBWM Capital Trust I in September 
1999.  We established MBWM Capital Trust I in 1999 to issue the trust preferred securities that were 
redeemed.  Substantially all of the net proceeds received by the company from the Series B transaction were 
contributed to our bank as capital.  The Series A and Series B Floating Rate Notes are categorized on our 
consolidated financial statements as subordinated debentures.  Additional information regarding Mercantile 
trust is incorporated by reference to “Note 15 – Subordinated Debentures” and “Note 16 – Regulatory Matters” 
of the Notes to Consolidated Financial Statements included in this Annual Report on pages F-54 through F-56.

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 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 

As a 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 that have not 

qualified as financial holding companies to banking and the management of banking organizations, and to 
certain non-banking activities.  These non-banking activities include those 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 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.  With the exception of the activities of our mortgage 
company discussed above, neither we nor any of our subsidiaries engages in any of the non-banking activities 
listed above. 

In March 2000, 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 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 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 or 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.  Other than the insurance agency activities of our 
insurance company, neither we nor our subsidiaries presently engage in any of the expanded activities. 

Our bank is subject to restrictions imposed by federal law and regulation.  Among other things, these 
restrictions apply to any extension of credit to us or to 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.  
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. 

4. 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
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 certain restrictions imposed by Federal 
and state laws and regulations. 

Employees 

As of December 31, 2006, we and our bank employed 256 full-time and 69 part-time persons.  

Management believes that relations with employees are good. 

Lending Policy 

As a routine part of our business, we make loans and leases 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 and leases 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 and leases 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 and leases, including the ability to pay; the character of the customer; 
evidence of financial responsibility; purpose of the loan or lease; 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 or leased 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 and lease to value limits 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 and lease identification, maintenance of an 
allowance for loan and lease losses, loan and lease 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, makes us responsive to our customers.  The loan policy currently specifies 
lending authority for certain officers up to $3.0 million, and $10.0 million for our bank’s Chairman of the 
Board and its President and Chief Executive Officer; however, the $10.0 million lending authority is generally 
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 $4.0 million, up to the legal 
lending limit of approximately $33.6 million, require approval by the Board of Directors.  In most 
circumstances, we apply an in-house lending limit that is significantly less than our bank’s legal lending limit. 

Lending Activity 

Commercial Loans.  Our commercial lending group originates commercial loans and leases primarily 
in our market areas.  Our commercial lenders have extensive commercial lending experience, with most having 
at least ten years’ experience.  Loans and leases 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. 

5. 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
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 an interest rate tied to the national prime rate.  Loans and leases 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 15 year 
period.  Commercial loans and leases typically have an interest rate that is fixed to maturity or is tied to the 
national prime rate. 

We evaluate many aspects of a commercial loan or lease 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.  This analysis includes a review of the borrower’s historical and projected 
financial results.  Appraisals are generally required 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 

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 of well-known customers or new customers whose businesses have an established profitable history.  
In many cases, risk is further reduced by 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 no material loans to energy producing customers.  We have 

only limited exposure to companies engaged in agricultural-related activities. 

Single-Family Residential Real Estate Loans.  Our mortgage company originates single-family 
residential real estate loans in our market area, usually according to secondary market underwriting standards.  
Loans not conforming to those standards are made in limited circumstances.  Single-family residential real 
estate loans provide borrowers with a fixed or adjustable interest rate with terms up to 30 years.   

Our bank has a home equity line of credit program.  Home equity credit is 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 national prime rate. 

Consumer Loans.  We originate consumer loans for a variety of personal financial needs, including 

new and used automobiles, boat loans, credit cards and overdraft protection 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 and Lease Portfolio Quality 

We utilize a comprehensive grading system for our commercial loans and leases as well as residential 
mortgage and consumer loans.  All commercial loans and leases are graded on a ten grade rating system.  The 
rating system utilizes standardized grade paradigms that analyze several critical factors such as cash flow, 
management and collateral coverage.  All commercial loans and leases are graded at inception and reviewed at 
various intervals thereafter.  Residential mortgage and consumer loans are graded on a four grade rating system 
using a separate standardized grade paradigm that analyzes several critical factors such as debt-to-income and 
credit and employment histories.  Residential mortgage and consumer loans are graded on a random sampling 
basis after the loan has been made. 

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

grading system and ensuring adherence to established lending policies and procedures.  The loan and lease 
review program is an integral part of maintaining our strong asset quality culture.  The loan and lease review 
function works closely with senior management, although it functionally reports to the Board of Directors.  All 
commercial loan and lease relationships equal to or exceeding $1.8 million are formally reviewed every twelve 
months, with a random sampling performed on credits under $1.8 million.  Our watch list credits are reviewed 
monthly by our Watch List Committee, which is comprised of personnel from the administration, lending and 
loan and lease review functions.   

Loans and leases are placed in a nonaccrual status when, in our opinion, uncertainty exists as to the 

ultimate collection of principal and interest.  As of December 31, 2006, loans and leases placed in nonaccrual 
status totaled $7.8 million, or 0.44% of total loans and leases.  As of the same date, loans and leases past due 
90 days or more and still accruing interest totaled $0.8 million, or 0.05% of total loans and leases.  As of 
December 31, 2006, there were no other significant loans and leases where known information about credit 
problems of borrowers warranted the placing of the loans or leases in a nonaccrual status.  We are not aware of 
any potential problem credits that could have a material adverse effect on our operating results, liquidity, or 
capital resources. 

Additional detail and information relative to the loan and lease portfolio is incorporated by reference 

to Management’s Discussion and Analysis of Financial Condition and Results of Operation (“Management’s 
Discussion and Analysis”) beginning on Page F-4 and Note 3 of the Consolidated Financial Statements on 
pages F-43 and F-44 included in this Annual Report. 

Allowance for Loan and Lease Losses 

In each accounting period, we adjust the allowance for loan and lease losses (“allowance”) to the 
amount we believe is necessary to maintain the allowance at adequate levels.  Through the loan and lease 
review and credit departments, we attempt to allocate specific portions of the allowance based on specifically 
identifiable problem loans and leases.  The evaluation of the allowance is further based on, but not limited to, 
consideration of the internally prepared Loan Loss Reserve Analysis (“Reserve Analysis”), composition of the 
loan and lease portfolio, third party analysis of the loan and lease administration processes and portfolio and 
general economic conditions.  In addition, the strong commercial loan and leases growth is taken into account.   

7. 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
The Reserve Analysis, used since our inception and completed monthly, applies reserve allocation 

factors to outstanding loan and lease balances to calculate an overall allowance dollar amount.  For commercial 
loans and leases, which continue to comprise a vast majority of our total loans and leases, reserve allocation 
factors are based upon the loan ratings as determined by our standardized grade paradigms.  For retail loans, 
reserve allocation factors are based upon the type of credit.  Adjustments for specific lending relationships, 
including impaired loans and leases, are made on a case-by-case basis.  The reserve allocation factors are 
primarily based on the recent levels and historical trends of net loan charge-offs and non-performing assets, the 
comparison of the recent levels and historical trends of net loan charge-offs and non-performing assets with a 
customized peer group consisting of ten similarly-sized publicly traded banking organizations conducting 
business in the states of Michigan, Illinois, Indiana and/or Ohio, the review and consideration of our loan 
migration analysis and the experience of senior management making similar loans and leases for an extensive 
period of time.  We regularly review the Reserve Analysis and make adjustments periodically based upon 
identifiable trends and experience. 

We believe that the present allowance is adequate, based on the broad range of considerations listed 

above.  

The primary risks associated with commercial loans and leases are the financial condition of the 

borrower, the sufficiency of collateral, and lack of timely payment.  We have a policy of requesting and 
reviewing periodic financial statements from its commercial loan and lease customers, and periodically 
reviewing existence of collateral and its value.  The primary risk element that we consider for consumer and 
residential real estate loan is lack of timely payment.  We have a reporting system that monitors past due loans 
and have adopted policies to pursue our creditor’s rights in order to preserve our bank’s collateral position. 

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

and Analysis beginning on Page F-4 and Note 3 of the Notes to Consolidated Financial Statements of the 
Company on pages F-43 and F-44 included in this Annual Report. 

Although we believe the allowance is adequate to absorb probable incurred losses as they arise, there 

can be no assurance that we will not sustain losses in any given period which could be substantial in relation to, 
or greater than, the size of the allowance. 

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 Mercantile trust.  Other funds of 
our bank holding company may be invested from time to time in various debt instruments. 

As a bank holding company, 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.  In addition, our bank holding company’s qualification as a financial holding company enables us 
to make equity investments in companies engaged in a broader range of financial activities than we could do 
without that qualification.  Such expanded activities include 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.  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. 

8. 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
In addition, so long as our bank holding company is qualified as a financial holding company, it would 

be permitted, as part of the business of underwriting or merchant banking activity and under certain 
circumstances and procedures, to invest in shares or other ownership interests in, or assets of, companies 
engaged in non-financial activities.  In order to make those investments, our bank holding company would be 
required (i) to become, or to have an affiliate that is, a registered securities broker or dealer or a registered 
municipal securities dealer, or (ii) to control both an insurance company predominantly engaged in 
underwriting life, accident and health, or property and casualty insurance (other than credit insurance) or 
issuing annuities, and a registered investment adviser that furnishes investment advice to an insurance company.  
We do not currently have any securities, insurance, or investment advisory affiliates of the required types, nor 
does our bank holding company have any current plans to make any of the equity investments described in this 
paragraph. 

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, our mortgage company, or 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 beginning on Page F-4 and Note 2 of the Notes to Consolidated 
Financial Statements on pages F-40 through F-42 included in this Annual Report.  

Competition 

Our primary markets for loans and core deposits are the Grand Rapids, Holland, Lansing and Ann 
Arbor metropolitan areas.  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 out-of-state 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 the Gramm-Leach-Bliley Act, effective March 11, 2000, securities firms and insurance 
companies that elect to become financial holding companies may acquire banks and other financial institutions.  
The Gramm-Leach-Bliley Act may significantly change 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.

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, south central, or 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. 

Our credit losses could increase and our allowance for loan and lease losses 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 collectibility of our loan portfolio and provide an allowance for losses 
based on several factors.  If our assumptions are wrong, our allowance for loan and lease losses may not be 
sufficient to cover our losses, which would have an adverse effect on our operating results.  While we have not 
experienced unusual amounts of charge-offs or nonperforming loans, we cannot assure you that we will not 
experience an increase in delinquencies and losses as the loans and leases continue to mature.  The actual 
amounts of future provisions for loan and lease losses cannot be determined at this time and may exceed the 
amounts of past provisions.  Additions to our allowance for loan and lease losses decrease our net income. 

10. 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
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 

Gerald R. Johnson, Jr., our Chairman and Chief Executive Officer, Michael H. Price, our President and Chief 
Operating Officer, and our other senior managers.  The loss of either Mr. Johnson or Mr. Price, or any of our 
other senior managers, could have an adverse effect on our growth and performance.  We have entered into 
employment contracts with Mr. Johnson and Mr. Price and two other executive officers.  The contracts provide 
for a three year employment period that is extended for an additional year each year unless a notice is given 
indicating that the contract will not be extended. 

In addition, we continue to depend on our city presidents and key commercial loan officers.  Our city 
presidents and several of our commercial loan officers are responsible, or share responsibility, for generating 
and managing a significant portion of our commercial loan and lease 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 and lease portfolio and 
performance, and our ability to generate new loans and leases.  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. 

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. 

Decline in the availability of out-of-area deposits could cause liquidity or interest rate margin concerns, 
or limit our growth. 

We have utilized and expect to continue to utilize out-of-area or wholesale deposits to support our 

asset growth.  These deposits are generally a lower cost source of funds when compared to the interest rates that 
we would have to offer in our local markets to generate a commensurate level of funds.  In addition, the 
overhead costs associated with wholesale deposits are considerably less than the overhead costs we would incur 
to obtain and administer a similar level of local deposits.  A decline in the availability of these wholesale 
deposits would require us to fund our growth with more costly funding sources, which could reduce our net 
interest margin, limit our growth, reduce our asset size, or increase our overhead costs. 

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 stock, including shares authorized and unissued under our Stock 
Incentive Plan of 2006.  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. 

11. 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Our growth and expansion may be limited by many factors. 

Our primary growth strategy has been to grow internally by increasing our business in the western 

Michigan area, and more recently in the Lansing and Ann Arbor areas of Michigan.  We are also considering 
other areas in which we may expand our business.  This internal growth strategy depends in large part on 
generating an increasing level of loans and deposits at acceptable risk and interest rate levels without 
commensurate increases in non-interest expenses.  There can be no assurance that we will be successful in 
continuing our growth strategy due to delays and other impediments resulting from regulatory oversight, limited 
availability of qualified personnel and favorable and cost effective branch sites, and management time, capital, 
and expenses required to develop new branch sites and markets.  In addition, the success of our growth strategy 
will depend on maintaining sufficient regulatory capital levels and on adequate economic conditions in our 
market areas. 

In addition, although we have no current plans to do so, we may acquire banks, related businesses or 
branches of other financial institutions that we believe provide a strategic fit with our business.  To the extent 
that we grow through acquisitions, we cannot assure you that we will be able to adequately or profitably 
manage this growth.  Acquiring other banks, businesses, or branches involves risks commonly associated with 
acquisitions, including exposure to unknown or contingent liabilities and asset quality issues, difficulty and 
expense of integrating the operations and personnel, potential disruption to our business including the diversion 
of management’s time and attention, and the possible loss of key employees and customers. 

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 
out-of-state 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.  Most 
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 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 the Gramm-Leach-Bliley Act of 1999, effective March 11, 2000, securities firms 
and insurance companies that elect to become financial holding companies may acquire banks and other 
financial institutions.  The Gramm-Leach-Bliley Act affects the competitive environment in which we conduct 
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. 

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, 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, 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. 

12. 

 
 
 
 
 
 
 
 
 
 
 
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.  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 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 interests. 

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 Bylaws, 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 offering price. 

We have paid a 5% stock dividend on our common stock each year since 2001, and have paid a 

quarterly cash dividend each quarter beginning with the first quarter of 2003.  While we expect to continue 
paying cash dividends, there is no assurance that we will continue to do so. 

13. 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
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 sufficiently adequate.  
We also face the risk that the design of our controls and procedures prove inadequate or are circumvented, 
causing delays in detection or errors in information.  Although we maintain a system of controls designed to 
keep operational risk 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. 

ITEM IB. 

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 2006 fiscal year 
and that remain unresolved. 

ITEM 2.  

PROPERTIES 

During 2005, our bank placed into service a new four-story facility located approximately two miles 
north from the center of downtown Grand Rapids.  Design and construction of this facility had started during 
2003.  This new facility serves as the Company’s headquarters and our bank’s main office, and houses the 
administration function, our bank’s commercial lending and review function, our bank’s loan operations 
function, a full service branch, portions of our bank’s retail lending and business development function and our 
bank’s retail brokerage operation.  A majority of functions housed at this facility were formerly operated out of 
a leased facility located at 216 North Division Avenue, Grand Rapids, Michigan, approximately two miles from 
the new facility.  The new facility consists of approximately 55,000 square feet of usable space and contains 
multiple drive-through lanes with ample parking.  The land and building are owned by our real estate company.  
The address of this facility is 310 Leonard Street NW, Grand Rapids, Michigan.   

Our bank designed and constructed a full service branch and retail loan facility which opened in July 

of 1999 in Alpine Township, a northwest suburb of Grand Rapids.  The facility is one story and has 
approximately 8,000 square feet of usable space.  The land and building are owned by our bank.  The facility 
has multiple drive-through lanes and ample parking space.  The address of this facility is 4613 Alpine Avenue 
NW, Comstock Park, Michigan.

During 2001, our bank designed and constructed two facilities on a 4-acre parcel of land located in the 

City of Wyoming, a southwest suburb of Grand Rapids.  The land had been purchased by our bank in 2000.  
The larger of the two buildings is a full service branch and deposit operations facility which opened in 
September of 2001.  The facility is two-stories and has approximately 25,000 square feet of usable space.  The 
facility is owned by our bank and has multiple drive-through lanes and ample parking space.  The address of 
this facility is 5610 Byron Center Avenue SW, Wyoming, Michigan.  The other building is a single-story 
facility with approximately 11,000 square feet of usable space.  Our bank’s accounting, audit, loss prevention 
and wire transfer functions are housed in this building, which underwent a renovation in 2005 that almost 
doubled its size.  This facility is also owned by our bank.  The address of this facility is 5650 Byron Center 
Avenue SW, Wyoming, Michigan. 

During 2002, our bank designed and constructed a full service branch which opened in December of 
2002 in the City of Kentwood, a southeast suburb of Grand Rapids.  The land had been purchased by our bank 
in 2001.  The facility is one story and has approximately 10,000 square feet of usable space.  The facility is 
owned by our bank and has multiple drive-through lanes and ample parking space.  The address of this facility 
is 4860 Broadmoor Avenue SW, Kentwood, Michigan. 

During 2003, our bank designed and constructed a full service branch in the northeast quadrant of the 

City of Grand Rapids.  The land had been purchased by our bank in 2002.  The facility is one story and has 
approximately 3,500 square feet of usable space.  The facility is owned by our bank and has multiple drive-
through lanes and ample parking space.  The address of this facility is 3156 Knapp Street NE, Grand Rapids, 
Michigan. 

During 2003, our bank designed and started construction of a new two-story facility located in 

Holland, Michigan.  This facility, which was completed during the fourth quarter of 2004, serves as a full 
service banking center for the Holland area, including commercial lending, retail lending and a full service 
branch.  The facility consists of approximately 30,000 square feet of usable space and contains multiple drive-
through lanes with ample parking.  The address of this facility is 880 East 16th Street, Holland, Michigan. 

During 2005, our bank opened a branch facility in the City of East Lansing, Michigan.  The facility is 

one story and has approximately 7,500 square feet of usable space.  The facility is operated under a lease 
agreement between our bank and a third party.  There is ample parking space, but no drive-through lanes.  The 
address of this facility is 1651 West Lake Lansing Road, East Lansing, Michigan. 

During 2005, our bank opened a branch facility in the City of Ann Arbor, Michigan.  The facility is 

one story and has approximately 10,000 square feet of usable space.  The facility is operated under a lease 
agreement between our bank and a third party.  There is ample parking space, but no drive-through lanes.  The 
address of this facility is 325 Eisenhower Parkway, Ann Arbor, Michigan. 

During 2006, our bank purchased approximately 3 acres of vacant land and designed and initiated 
construction of a new three-story facility in East Lansing, Michigan.  This facility, which is expected to be 
completed during the second quarter of 2007, will serve as a full service banking center for the greater Lansing 
area, including commercial lending, retail lending, and a full service branch.  The facility will consist of 
approximately 27,000 square feet of usable space and will contain multiple drive-through lanes with ample 
parking.  When completed, this facility will replace the leased facility noted above located on West Lake 
Lansing Road in East Lansing.  The address of this facility is 3737 Coolidge Road, East Lansing, Michigan. 

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

ITEM 5.    MARKET FOR REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER 

MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES 

Our common stock is listed on the Nasdaq Global Select Market under the symbol “MBWM”.  At 
February 12, 2007, there were 305 record holders of our common stock.  In addition, we estimate that there 
were approximately 4,000 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 cash dividends paid by us during those 
periods.  The prices have been adjusted for the 5% stock dividends paid on May 16, 2006 and August 1, 2005.

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 holding company and substantially all of our assets are held by our 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. 

On January 9, 2007, we declared a $0.14 per share cash dividend on our common stock, payable on 
March 9, 2007 to record holders as of February 9, 2007.  We currently expect to continue to pay a quarterly 
cash dividend, although there can be no assurance that we will continue to do so.

CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON 
ACCOUNTING AND FINANCIAL DISCLOSURE 

On September 14, 2006, our Audit Committee concluded its proposal process for selection of an 

independent registered public accounting firm for 2007, and appointed BDO Seidman, LLP as our independent 
registered public accounting firm for the calendar year ending December 31, 2007.  On the same date, our 
Audit Committee determined to dismiss Crowe Chizek and Company LLC as our independent registered public 
accounting firm after it completed its work for the calendar year ending December 31, 2006, and advised 
Crowe Chizek and Company LLC that it would not be engaged as our independent registered public accounting 
firm for the calendar year ending December 31, 2007.  We filed a report on Form 8-K with the Securities and 
Exchange Commission on September 19, 2006 reporting the change of accountants and making related 
disclosures. 

ITEM 9A.  

CONTROLS AND PROCEDURES 

As of December 31, 2006, 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, 2006.  There have been no significant 
changes in our internal controls over financial reporting during the quarter ended December 31, 2006, 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).  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 based on the 
framework in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations 
of the Treadway Commission.  Based on our evaluation under the framework in Internal Control – Integrated 
Framework, our management concluded that our internal control over financial reporting was effective as of 
December 31, 2006.  Our management’s assessment of the effectiveness of our internal control over financial 
reporting as of December 31, 2006 has been audited by Crowe Chizek and Company LLC, an independent 
registered public accounting firm, as stated in their report 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 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; changes in tax 
laws; changes in prices, levies, and assessments; the impact of technological advances; governmental and regulatory 
policy changes; the outcomes of contingencies; trends in customer behavior as well as their ability to repay loans; 
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 preceding forward-looking statement. 

CRITICAL ACCOUNTING POLICIES AND ESTIMATES 

The Management’s Discussion and Analysis of Financial Condition and Results of Operations 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 and lease losses, and actual results could differ from those estimates. 

The allowance for loan and lease losses is maintained at a level we believe is adequate to absorb probable incurred 
losses identified and inherent in the loan and lease portfolio.  Our evaluation of the adequacy of the allowance for 
loan and lease losses is an estimate based on reviews of individual loans, assessments of the impact of current and 
anticipated economic conditions on the portfolio, and historical loss experience.  The allowance for loan and lease 
losses represents management’s best estimate, but significant downturns in circumstances relating to loan and lease 
quality or economic conditions could result in a requirement for an increased allowance for loan and lease losses in 
the near future.  Likewise, an upturn in loan and lease quality or improved economic conditions may result in a 
decline in the required allowance for loan and lease losses.  In either instance, unanticipated changes could have a 
significant impact on operating earnings. 

The allowance for loan and lease losses is increased through a provision charged to operating expense.  
Uncollectible loans and leases are charged-off through the allowance for loan and lease losses.  Recoveries of loans 
and leases previously charged-off are added to the allowance for loan and lease losses.  A loan is considered 
impaired when it is probable that contractual interest and principal payments will not be collected either for the 
amounts or by the dates as scheduled in the loan agreement.  Our policy for recognizing income on impaired loans is 
to accrue interest unless a loan is placed on nonaccrual status.

INTRODUCTION 

This Management’s Discussion and Analysis should be read in conjunction with the consolidated financial 
statements contained in this Annual Report.  This discussion provides information about the consolidated financial 
condition and results of operations of Mercantile Bank Corporation and its consolidated subsidiary, Mercantile Bank 
of Michigan (“our bank”), and of Mercantile Bank Mortgage Company, LLC (“our mortgage company”), Mercantile 
Bank Real Estate Co., L.L.C. (“our real estate company”) and Mercantile Insurance Center, Inc. (“our insurance 
company”), which are subsidiaries of our bank.  Unless the text clearly suggests otherwise, references to “us,” “we,” 
“our,” or “the company” include Mercantile Bank Corporation and its wholly-owned subsidiaries referred to above. 

We were incorporated on July 15, 1997 as a bank holding company to establish and own our bank.  Our bank, after 
receiving all necessary regulatory approvals, began operations on December 15, 1997.  Our bank has a strong 
commitment to community banking and offers a wide range of financial products and services, primarily to small- to 
medium-sized businesses, as well as individuals.  Our bank’s lending strategy focuses on commercial lending, and, to 
a lesser extent, residential mortgage and consumer lending.  Our bank also offers a broad array of deposit products, 
including checking, savings, money market, and certificates of deposit, as well as security repurchase agreements.  
Our primary markets are the Grand Rapids, Holland, Lansing and Ann Arbor metropolitan areas.  Our bank utilizes 
certificates of deposit from customers located outside of the primary market area to assist in funding the rapid asset 
growth our bank has experienced since inception. 

We formed a business trust, Mercantile Bank Capital Trust I (“the trust”), in 2004 to issue trust preferred securities.  
We issued subordinated debentures to the trust in return for the proceeds raised from the issuance of the trust 
preferred securities.  In accordance with FASB Interpretation No. 46, the trust is not consolidated, but instead we 
report the subordinated debentures issued to the trust as a liability. 

Our mortgage company’s predecessor, Mercantile Bank Mortgage Company, was formed to increase the profitability 
and efficiency of the company’s mortgage loan operations.  Mercantile Bank Mortgage Company initiated business 
on October 24, 2000 from our bank’s contribution of most of its residential mortgage loan portfolio and participation 
interests in certain commercial mortgage loans.  On the same date, our bank had also transferred its residential 
mortgage origination function to Mercantile Bank Mortgage Company.  On January 1, 2004, Mercantile Bank 
Mortgage Company was reorganized as Mercantile Bank Mortgage Company, LLC, a limited liability company.  
Mortgage loans originated and held by our mortgage company are serviced by our bank pursuant to a servicing 
agreement. 

Our insurance company acquired, at nominal cost, 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. 
Our real estate company was organized on July 21, 2003, principally to develop, construct and own our new facility 
in downtown Grand Rapids which serves as our bank’s new main office and Mercantile Bank Corporation’s 
headquarters.  Construction was completed during the second quarter of 2005. 

FINANCIAL CONDITION 

We continued to experience strong asset growth during 2006.  Assets increased from $1,838.2 million on December 
31, 2005 to $2,067.3 million on December 31, 2006.  This represents an increase in total assets of $229.1 million, or 
12.5%.  The increase in total assets was primarily comprised of a $182.8 million increase in net loans and leases, a 
$20.8 million increase in securities and a $14.6 million increase in cash and cash equivalents.  The increase in assets 
was primarily funded by a $227.6 million increase in deposits, a $13.3 million increase in repurchase agreements and 
a $16.8 million increase in shareholders’ equity.

Earning Assets 
Average earning assets equaled 94.9% of average total assets during 2006, compared to 94.8% during 2005.  
Although we experienced strong asset growth during 2006, the asset composition remained relatively constant.  The 
loan portfolio continued to comprise a majority of earning assets, followed by securities and federal funds sold. 

Our loan and lease portfolio, which equaled 89.2% of average earnings assets during 2006, is primarily comprised of 
commercial loans and leases.  Constituting over 92% of loans and leases and growing by $177.3 million during 
2006, the commercial loan and lease portfolio represents loans to businesses generally located within our market 
areas.  Approximately 70% of the commercial loan and lease portfolio is primarily secured by real estate properties, 
with the remaining generally secured by other business assets such as accounts receivable, inventory, and equipment.  
The continued significant concentration of the loan and lease portfolio in commercial loans and leases and the strong 
growth of this portion of our lending business are consistent with our strategy of focusing a substantial amount of our 
efforts on “wholesale” banking.  Corporate and business lending continues to be an area of expertise for our senior 
management team, and our commercial lenders have extensive commercial lending experience, with most having at 
least ten years’ experience.  Of each of the loan categories that we originate, commercial loans and leases are most 
efficiently originated and managed, thus limiting overhead costs by necessitating the attention of fewer full-time 
employees.  Our commercial lending business generates the greatest amount of local deposits and is virtually our 
only source of significant demand deposits.   

Residential mortgage and consumer loans, while equaling less than 8% of total loans and leases during 2006, also 
experienced strong growth; however, while we expect the residential mortgage loan and consumer loan portfolios to 
increase in future periods, the commercial sector of the lending efforts and resultant assets are expected to remain the 
dominant loan portfolio category given our wholesale banking strategy. 

The following tables present the maturity of total loans outstanding as of December 31, 2006, according to scheduled 
repayments of principal on fixed rate loans and repricing frequency on variable rate loans.  Floating rate loans that 
are currently at interest rate ceilings, totaling $281.0 million as of December 31, 2006, are treated as fixed rate loans 
and are reflected using maturity date and not repricing frequency.

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 “Watch List.”  Senior management reviews this list regularly.

Although the level of net loan and lease charge-offs and nonperforming loans and leases increased during 2006, the 
quality of our loan portfolio remains good.  The levels of net loan and lease charge-offs and nonperforming loans 
and leases approximated banking industry averages during 2006, compared to levels that were below banking 
industry averages in prior years.  As of December 31, 2006, nonperforming loans and leases totaled $8.6 million, or 
0.49% of total loans and leases.  At December 31, 2005, nonperforming loans and leases totaled $4.0 million, or 
0.26% of total loans and leases.  Net loan and lease charge-offs during 2006 totaled $4.9 million, or 0.29% of 
average total loans and leases.  During 2005, net loan and lease charge-offs totaled $1.1 million, or 0.08% of average 
total loans and leases.  Over 98% of the loan and lease portfolio consists of loans and leases extended directly to 
companies or individuals doing business and residing within our market areas.  The remaining portion is comprised 
of commercial loans participated with certain unaffiliated commercial banks outside of our market areas, which are 
underwritten using the same loan criteria as though our bank was the originating bank.

In each accounting period, we adjust the allowance to the amount we believe is necessary to maintain the allowance 
at adequate levels.  Through the loan and lease review and credit departments, we attempt to allocate specific 
portions of the allowance based on specifically identifiable problem loans and leases.  The evaluation of the 
allowance is further based on, but not limited to, consideration of the internally prepared Reserve Analysis, 
composition of the loan and lease portfolio, third party analysis of the loan and lease administration processes and 
portfolio and general economic conditions.  In addition, the strong commercial loan and leases growth is taken into 
account.   

The Reserve Analysis, used since our inception and completed monthly, applies reserve allocation factors to 
outstanding loan and lease balances to calculate an overall allowance dollar amount.  For commercial loans and 
leases, which continue to comprise a vast majority of our total loans and leases, reserve allocation factors are based 
upon the loan ratings as determined by our standardized grade paradigms.  For retail loans, reserve allocation factors 
are based upon the type of credit.  Adjustments for specific lending relationships, including impaired loans and 
leases, are made on a case-by-case basis.  The reserve allocation factors are primarily based on the recent levels and 
historical trends of net loan charge-offs and non-performing assets, the comparison of the recent levels and historical 
trends of net loan charge-offs and non-performing assets with a customized peer group consisting of ten similarly-
sized publicly traded banking organizations conducting business in the states of Michigan, Illinois, Indiana and/or 
Ohio, the review and consideration of our loan migration analysis and the experience of senior management making 
similar loans and leases for an extensive period of time.  We regularly review the Reserve Analysis and make 
adjustments periodically based upon identifiable trends and experience.

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

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

The securities portfolio also experienced strong growth during 2006, increasing from $181.6 million on December 
31, 2005 to $202.4 million at December 31, 2006.  During 2006, the securities portfolio equaled 10.2% of average 
earning assets.  We maintain the portfolio at levels to provide adequate pledging for the repurchase agreement 
program and secondary liquidity for our daily operations.  In addition, the portfolio serves a primary interest rate risk 
management function.  At December 31, 2006, the portfolio was comprised of high credit quality U.S. Government 
Agency issued bonds (38%), municipal general obligation and revenue bonds (32%), U.S. Government Agency 
issued and guaranteed mortgage-backed securities (26%), Federal Home Loan Bank stock (4%) and a mutual fund 
(less than 1%).

All securities, with the exception of tax-exempt municipal bonds, have been designated as “available for sale” as 
defined in Financial Accounting Standards Board Standard (SFAS) No. 115, Accounting for Certain Investments in 
Debt and Equity Securities.  Securities designated as available for sale are stated at fair value, with the unrealized 
gains and losses, net of income tax, reported as a separate component of shareholders’ equity in accumulated other 
comprehensive income.  The fair value of securities designated as available for sale at December 31, 2006 and 2005 
was $131.0 million and $113.0 million, respectively.  The net unrealized loss recorded at December 31, 2006 was 
$1.7 million, compared to the net unrealized loss of $2.2 million as of December 31, 2005.  All tax-exempt 
municipal bonds have been designated as “held to maturity” as defined in SFAS No. 115, and are stated at amortized 
cost.  As of December 31, 2006 and 2005, held to maturity securities had an amortized cost of $63.9 million and 
$60.8 million and a fair value of $65.0 million and $62.9 million, respectively.

Federal funds sold, consisting of excess funds sold overnight to correspondent banks, are used to manage daily 
liquidity needs and interest rate sensitivity.  During 2006, the average balance of these funds equaled 0.5% of 
average earning assets, unchanged from the level during 2005.  The levels maintained during 2006 and 2005 are well 
within our internal policy guidelines, and future levels are not expected to change significantly. 

Cash and due from bank balances increased from $36.2 million at December 31, 2005, to $51.4 million on 
December 31, 2006, an increase of $15.2 million.  The increase was primarily the result of larger amounts of 
deposits made by our deposit customers on the last business day of 2006 when compared to the last business day of 
2005.  Our commercial lending and wholesale funding focus results in relatively large day-to-day fluctuations of our 
cash and due from bank balances; however, relative to our asset size the average balances are generally stable.  Cash 
and due from bank balances averaged $38.3 million, or 2.0% of average assets during 2006, compared to $36.8 
million, or 2.2% of average assets, during 2005. 

Net premises and equipment increased from $30.2 million at December 31, 2005, to $33.5 million on December 31, 
2006, an increase of $3.3 million.  The increase primarily reflects the land acquisition and initial construction costs 
associated with our new office facility currently under construction in East Lansing, Michigan.  Construction on this 
new facility is expected to be completed during the second quarter of 2007. 

Source of Funds 
Our major sources of funds are from deposits, repurchase agreements and Federal Home Loan Bank (“FHLB”) 
advances.  Total deposits increased from $1,419.4 million at December 31, 2005, to $1,646.9 million on December 
31, 2006, an increase of $227.5 million, or 16.0%.  Included within these numbers is the success we achieved in 
generating deposit growth from customers located within our market areas during 2006.  Local deposits increased 
from $456.5 million at December 31, 2005, to $633.1 million on December 31, 2006, an increase of $176.6 million, 
or 38.7%.  Despite this success in obtaining funds from local customers, the substantial asset growth has necessitated 
the continued acquisition of funds from depositors outside of our market areas and FHLB advances.  Out-of-area 
deposits increased from $962.8 million at December 31, 2005, to $1,013.8 million on December 31, 2006, an 
increase of $51.0 million, or 5.3%.  Repurchase agreements increased from $72.2 million at December 31, 2005, to 
$85.5 million on December 31, 2006, an increase of $13.3 million, or 18.4%.  FHLB advances decreased from 
$130.0 million at December 31, 2005, to $95.0 million on December 31, 2006, a decrease of $35.0 million, or 
26.9%.  At December 31, 2006, local deposits and repurchase agreements equaled 38.4% of total funding liabilities, 
compared to 31.8% on December 31, 2005. 

During 2006, we experienced strong growth in our noninterest-bearing checking deposit accounts.  Comprised 
primarily of business loan customers, noninterest-bearing checking deposit accounts grew $12.4 million, or 10.2%, 
and equaled 6.4% of average total liabilities during 2006.  Interest-bearing checking accounts increased $0.2 million, 
or 0.4%, and equaled 2.0% of average total liabilities during 2006.  Money market deposit accounts decreased $0.9 
million, or 9.0%, and equaled 0.6% of average total liabilities during 2006.  Business loan customers also comprise 
the majority of interest-bearing checking and money market deposit accounts, although to a lesser extent than 
noninterest-bearing checking accounts.  Pursuant to Federal law and regulations, incorporated businesses may not 
own interest-bearing checking accounts and transactions from money market accounts are limited.  We anticipate 
continued overall growth of our check-writing deposit accounts as additional business loans are extended and 
through the efforts of our branch network and business development activities. 

During 2006, savings account balances recorded a decrease of $13.9 million, or 13.1%, and equaled 5.2% of average 
total liabilities.  The decline in savings account balances during 2006 is primarily due to customers opening 
certificates of deposit with funds from their savings accounts, as rates offered on certificates of deposit have risen at 
a faster pace than rates offered on savings accounts.  Business loan customers also comprise the majority of savings 
account holders, although to a lesser extent than check-writing accounts.  While we anticipate an increase in savings 
account balances as additional business loans are extended and through the efforts of our branch network and 
business development activities, the increase may be negatively impacted by potential continued fund transfers to 
certificate of deposit products.

Certificates of deposit purchased by customers located within our market areas increased significantly during 2006, 
growing from $179.3 million at December 31, 2005, to $358.2 million on December 31, 2006, an increase of $178.9 
million, or 99.8%.  These deposits accounted for 15.9% of average total liabilities during 2006.  The growth was 
attributable to individuals, businesses and municipalities, and includes new monies to our bank from existing and 
new customers as well as transfers from existing savings accounts.  The increase in local municipality certificates of 
deposit has been facilitated by our qualifying for funds from new municipal customers and additional funds from 
existing customers through a combination of our asset growth and increased profitability as measured by the 
municipalities’ investment policy guidelines, and is a trend that we expect to continue. 

During 2006, certificates of deposit obtained from customers located outside of our market areas increased by $51.0 
million, and represented 55.9% of average total liabilities.  At December 31, 2006, out-of-area deposits totaled 
$1,013.8 million.  Out-of-area deposits consist primarily of certificates of deposit placed by deposit brokers for a fee, 
but also include certificates of deposit obtained from the deposit owners directly.  The owners of the out-of-area 
deposits include individuals, businesses and governmental units located throughout the country.  Out-of-area deposits 
are utilized to support our asset growth, and are generally a lower cost source of funds when compared to the interest 
rates that would have to be offered in the local market to generate a sufficient level of funds.  During most of 2006, 
rates paid on new out-of-area deposits were very similar to rates paid on new certificates of deposit issued to local 
customers.  In addition, the overhead costs associated with the out-of-area deposits are considerably less than the 
overhead costs that would be incurred to administer a similar level of local deposits.  Although local deposits have 
and are expected to increase as new business, governmental and individual deposit relationships are established and 
as existing customers increase the balances in their deposit accounts, the relatively high reliance on out-of-area 
deposits will likely remain. 

Repurchase agreements increased $13.3 million and equaled 4.0% of average total liabilities during 2006.  As part of 
our sweep account program, collected funds from certain business noninterest-bearing checking accounts are 
invested in overnight interest-bearing repurchase agreements.   Although not considered a deposit account and 
therefore not afforded federal deposit insurance, the repurchase agreements are a means of providing a return for 
business customers that are not permitted to have an interest-bearing checking account.   

FHLB advances decreased $35.0 million and equaled 6.8% of average total liabilities during 2006.  FHLB advances 
are collateralized by residential mortgage loans, first mortgage liens on multi-family residential property loans, first 
mortgage liens on commercial real estate property loans, and substantially all other assets of our bank, under a 
blanket lien arrangement.  Our borrowing line of credit at December 31, 2006 totaled $322.6 million.  We first 
started to use FHLB advances in late 2002, and expect to continue to use this funding source, along with out-of-area 
certificates of deposit, as part of our wholesale funding program. 

Shareholders’ equity increased $16.8 million and equaled 8.3% of average assets during 2006.  The increase was 
primarily attributable to net income from operations.  Net income from operations totaled $19.8 million during 2006.  
Also positively impacting shareholders’ equity was a $0.3 million mark-to-market adjustment for available for sale 
securities as defined in SFAS No. 115, plus proceeds totaling $0.4 million relating to stock option exercises and our 
dividend reinvestment and employee stock purchase plans.  Negatively impacting shareholders’ equity during 2006 
was the payment of cash dividends, which totaled $4.0 million.   

RESULTS OF OPERATIONS 
FOR THE YEARS ENDED DECEMBER 31, 2006 and 2005 

Summary 
We recorded strong earnings performance during 2006.  Net income was $19.8 million, or $2.48 per basic share and 
$2.45 per diluted share.  This earnings performance compares favorably to net income of $17.9 million, or $2.25 per 
basic share and $2.20 per diluted share, recorded in 2005.  The $1.9 million improvement in net income represents 
an increase of 10.9%, while diluted earnings per share were up 11.4%.  The earnings improvement during 2006 over 
that of 2005 is primarily attributable to higher net interest income, which more than offset increases in provision 
expense and overhead costs.

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 $138.5 million and $75.7 million during 2006, respectively, providing for net interest income of 
$62.8 million.  This performance compares favorably to that of 2005 when interest income and interest expense were 
$103.2 million and $46.8 million, respectively, providing for net interest income of $56.4 million.  In comparing 
2006 with 2005, interest income increased 34.1%, interest expense was up 61.6% and net interest income increased 
11.3%.  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 of assets and liabilities, interest rate environment, interest rate risk, common stock sales, liquidity, and 
customer behavior also impact net interest income as well as the net interest margin.   

The net interest margin declined from 3.50% in 2005 to 3.37% in 2006, a decrease of 3.7%.  Our net interest margin 
during 2004 was 3.30%.  Throughout 2005 and during the first half of 2006, our net interest margin was generally on 
an increasing trend.  From June 2004 through June 2006, the Federal Open Market Committee (“FOMC”) increased 
the federal funds rate by 25 basis points at 17 consecutive meetings, causing the prime rate to increase from 4.00% in 
June 2004 to 8.25% in June 2006.  Our yield on assets increased significantly during this time period, as the interest 
rates on over 70% of our total loans and leases were tied to the prime rate.  Our cost of funds also increased during 
this time period, as interest rates paid on our deposits and borrowings increased as well.  However, our cost of funds 
increased at a slower rate than the increase in our yield on assets, with a significant portion of our interest-bearing 
liabilities comprised of fixed rate certificates of deposit and borrowings, resulting in a lagged increased cost of funds.  
The FOMC has left the federal funds rate unchanged since June 2006, resulting in a relatively steady yield on assets.  
However, our cost of funds has continued to increase as maturing fixed rate certificates of deposit and borrowings, 
which were obtained during lower interest rate environments, are replaced or renewed at higher interest rates.  
Assuming no major changes in the federal funds rate in the near future, we expect our cost of funds, and therefore 
our net interest margin, to level-out during the second quarter of 2007. 

The following table depicts the average balance, interest earned and paid, and weighted average rate of our assets, 
liabilities and shareholders’ equity during 2006, 2005 and 2004.  The table also depicts the dollar amount of change 
in interest income and interest expense of interest-earning assets and interest-bearing liabilities, 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 $1.2 million, $1.1 million and $1.0 million in 2006, 2005 and 2004, respectively.

Interest income is primarily generated from the loan and lease portfolio, and to a lesser degree from securities, 
federal funds sold and short term investments.  Interest income increased $35.3 million during 2006 from that earned 
in 2005, totaling $138.5 million in 2006 compared to $103.2 million in the previous year.  The increase is primarily 
due to the growth in earning assets and a higher interest rate environment during 2006 when compared to 2005.  
Reflecting the higher interest rate environment, the yield on average earning assets increased from 6.40% recorded in 
2005 to 7.44% in 2006.   

The growth in interest income is primarily attributable to an increase in earning assets and an increase in earning 
asset yields.  During 2006, average earning assets increased $247.3 million, increasing from $1,613.4 million in 
2005 to $1,860.7 million during 2006.  Growth in average total loans and leases, totaling $227.7 million, comprised 
92.1% of the increase in average earning assets during 2006.  Interest income generated from the loan and lease 
portfolio increased $33.8 million during 2006 over the level earned in 2005, comprised of an increase of $16.1 
million from the growth in the loan and lease portfolio and an increase of $17.7 million due to the increase in the 
yield earned on the loan portfolio to 7.68% from 6.54%.  The increase in the loan and lease portfolio yield is 
primarily due to a higher interest rate environment during 2006 than in 2005. 

Growth in the securities portfolio and an improved overall yield also added to the increase in interest income during 
2006 over that of 2005.  Average securities increased by $18.2 million in 2006, increasing from $172.1 million in 
2005 to $190.3 million in 2006.  The growth equated to an increase in interest income of $1.0 million, while an 
improved yield earned on the securities portfolio from 5.40% to 5.51% increased interest income by $0.2 million.  
Interest income earned on federal funds sold increased by $0.2 million due to a small increase in the average balance 
and a higher yield during 2006. 

Interest expense is primarily generated from interest-bearing deposits, and to a lesser degree from repurchase 
agreements, FHLB advances and subordinated debentures.  Interest expense increased $28.8 million during 2006 
from that expensed in 2005, totaling $75.6 million in 2006 compared to $46.8 million in the previous year.  The 
increase in interest expense is primarily attributable to the impact of an increase in interest-bearing liabilities and a 
higher interest rate environment during 2006 when compared to 2005.  Interest-bearing liabilities averaged $1,663.4 
million during 2006, or $234.2 million higher than the average interest-bearing liabilities of $1,429.2 million during 
2005.  This growth resulted in increased interest expense of $9.3 million.  An increase in interest expense of $19.6 
million was recorded during 2006 primarily due to a higher interest rate environment during 2006 than in 2005.  The 
cost of average interest-bearing liabilities increased from the 3.28% recorded in 2005 to 4.55% in 2006.

Average certificate of deposit growth during 2006 of $253.3 million equated to an increase in interest expense of 
$9.8 million, with an additional $15.2 million expensed due to the increase in the average rate paid as lower-rate 
certificates of deposit matured and were either renewed or replaced with higher-costing certificates of deposit 
throughout 2006.  A decline in average savings deposits, totaling $20.9 million, equated to a decrease in interest 
expense of $0.6 million; however, interest expense of $1.0 million was recorded due to an increase in the average 
rate paid during 2006.  Growth in average interest-bearing checking accounts of $0.2 million equated to a less than 
$0.1 million increase in interest expense, with an additional $0.4 million of interest expense recorded due to a higher 
average rate paid during 2006. 

Average short term borrowings, comprised of repurchase agreements and federal funds purchased, increased $9.1 
million during 2006, resulting in increased interest expense of $0.3 million, with an additional interest expense of 
$0.8 million recorded due to an increase in the average rate paid during 2006.  Average FHLB advances decreased 
$9.2 million, equating to a decrease in interest expense of $0.3 million, with an increased average rate adding $1.5 
million to interest expense.  Growth in average long-term borrowings, comprised of subordinated debentures and 
deferred director and officer compensation programs, equated to an increase in interest expense of less than $0.1 
million during 2006, with an increased average rate adding $0.6 million to interest expense. 

Provision for Loan and Lease Losses 
The provision for loan and lease losses totaled $5.8 million during 2006, compared to the $3.8 million expensed 
during 2005.  The increase primarily reflects an increase in the volume of loan and lease net charge-offs during 2006 
when compared to 2005, partially offset by lower loan and lease growth in 2006.  Net loan and lease charge-offs 
during 2006 totaled $4.9 million, or 0.29% of average total loans and leases.  Net loan and lease charge-offs during 
2005 totaled $1.1 million, or 0.08% of average total loans and leases.  Loan and lease growth during 2006 equaled 
$183.7 million, compared to loan and lease growth of $244.7 million during 2005.  The allowance as a percentage of 
total loans outstanding as of December 31, 2006 was 1.23%, compared to 1.31% at year-end 2005.   

In each accounting period, we adjust the allowance by the amount we believe is necessary to maintain the allowance 
at adequate levels.  Through the loan and lease review and credit departments, we attempt to allocate specific 
portions of the allowance based on specifically identifiable problem loans and leases.  The evaluation of the 
allowance is further based on, but not limited to, consideration of the internally prepared Reserve Analysis, 
composition of the loan and lease portfolio, third party analysis of the loan and lease administration processes and 
portfolio and general economic conditions.  In addition, the strong commercial loan and leases growth is taken into 
account.   

The Reserve Analysis, used since our inception and completed monthly, applies reserve allocation factors to 
outstanding loan and lease balances to calculate an overall allowance dollar amount.  For commercial loans and 
leases, which continue to comprise a vast majority of our total loans and leases, reserve allocation factors are based 
upon the loan ratings as determined by our standardized grade paradigms.  For retail loans, reserve allocation factors 
are based upon the type of credit.  Adjustments for specific lending relationships, including impaired loans and 
leases, are made on a case-by-case basis.  The reserve allocation factors are primarily based on the recent levels and 
historical trends of net loan charge-offs and non-performing assets, the comparison of the recent levels and historical 
trends of net loan charge-offs and non-performing assets with a customized peer group consisting of ten similarly-
sized publicly traded banking organizations conducting business in the states of Michigan, Illinois, Indiana and/or 
Ohio, the review and consideration of our loan migration analysis and the experience of senior management making 
similar loans and leases for an extensive period of time.  We regularly review the Reserve Analysis and make 
adjustments periodically based upon identifiable trends and experience.

Noninterest Income 
Noninterest income totaled $5.3 million in 2006, a decrease of $0.4 million from the $5.7 million earned in 2005.  
Other noninterest income during 2005 included a one-time gain of $0.7 million which was recorded from the sale of 
state tax credits derived from the construction of the new main office in downtown Grand Rapids.  Deposit and 
repurchase agreement service charges were unchanged in 2006 when compared to 2005; although the number of 
deposit accounts increased during 2006, the earnings credit rate also increased, reducing the level of fees paid by our 
depositors.  Earnings from increased cash surrender value of bank owned life insurance policies increased $0.2 
million in 2006, primarily reflecting a higher balance from the purchase of additional policies during the year.  We 
recorded increases in virtually all other fee income-producing activities in 2006 when compared to 2005, with the 
exception of residential mortgage banking fees, which decreased $0.1 million due to lower volume of activity. 

Noninterest Expense 
Noninterest expense during 2006 totaled $32.3 million, an increase of $1.2 million over the $31.1 million expensed 
in 2005.  Salary expense and benefit costs increased $0.3 million in 2006 when compared to 2005.  Base 
compensation increased approximately $2.9 million, primarily reflecting the increase in full-time equivalent 
employees from 273 at year-end 2005 to 291 at year-end 2006 and annual pay increases.  However, bonus expense 
declined $2.6 million during 2006 when compared to 2005.  Occupancy, furniture and equipment costs increased 
$0.9 million in 2006, primarily reflecting a full year’s expense associated with the opening of our new main office in 
downtown Grand Rapids during the second quarter of 2005, and the opening of our new leased facilities in Lansing 
and Ann Arbor during the third quarter of 2005.  All other non-interest expenses, in aggregate, were relatively 
unchanged in 2006 when compared to 2005. 

While the dollar amount of noninterest costs has increased, the growth of net interest income and fee income has 
increased more.  Noninterest costs during 2006 were $1.2 million higher than the level of overhead costs expensed 
during 2005; however, net interest income and fee income increased a combined $5.9 million during the same time 
period.  Monitoring and controlling our noninterest costs, while at the same time providing high quality service to 
our customers, is one of our priorities.  The efficiency ratio, a banking industry standardized calculation that attempts 
to reflect the utilization of overhead costs, improved during 2006 and remained well below banking industry 
averages.  Computed by dividing noninterest expenses by net interest income plus noninterest income, the efficiency 
ratio was 48.3% during 2006, compared to 51.1% during 2005. 

Federal Income Tax Expense 
Federal income tax expense was $9.0 million in 2006, an increase of $0.9 million over the $8.1 million expensed 
during 2005.  The increase during 2006 is primarily due to the growth in our pre-federal income tax profitability.  
The effective tax rate for 2006 was 31.1%, compared to 31.3% in 2005. 

RESULTS OF OPERATIONS 
FOR THE YEARS ENDED DECEMBER 31, 2005 AND 2004 

Summary 
We recorded strong earnings performance during 2005.  Net income was $17.9 million, or $2.25 per basic share and 
$2.20 per diluted share.  This earnings performance compares favorably to net income of $13.7 million, or $1.73 per 
basic share and $1.69 per diluted share, recorded in 2004.  The $4.2 million improvement in net income represents 
an increase of 30.5%, while diluted earnings per share were up 30.2%.  The earnings improvement during 2005 over 
that of 2004 is primarily attributable to higher net interest income and a lower provision expense, which more than 
offset an increase in overhead costs. 

Net income for 2004 includes an $845,000 ($548,000 after-tax) write-off associated with the unamortized balance of 
issuance costs related to the redemption of the $16.0 million of 9.60% Cumulative Preferred Securities issued in 
1999 by MBWM Capital Trust I.  Excluding this one-time expense, net income for 2004 was $14.3 million ($1.80 
per basic share and $1.76 per diluted share).  We believe excluding the impact of the one-time charge from 2004 
operating results and performance measures allows a more meaningful comparison of 2005 results to 2004 results; 
therefore, the following discussion of our results of operations for the years ended December 31, 2005 and 
December 31, 2004 includes both GAAP and non-GAAP facts and figures where appropriate.

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 $103.2 million and $46.8 million during 2005, respectively, providing for net interest income of 
$56.4 million.  This performance compares favorably to that of 2004 when interest income and interest expense were 
$70.0 million and $26.6 million, respectively, providing for net interest income of $43.4 million.  In comparing 2005 
with 2004, interest income increased 47.4%, interest expense was up 76.0% and net interest income increased 
30.0%.  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 of assets and liabilities, interest rate risk, common stock sales, liquidity, and customer behavior also 
impact net interest income as well as the net interest margin.  The net interest margin improved from 3.30% in 2004 
to 3.50% in 2005, an increase of 6.1%, primarily due to earning assets repricing faster than interest-bearing liabilities 
during the increasing interest rate environment that existed during virtually all of 2005. 

Interest income is primarily generated from the loan portfolio, and to a lesser degree from securities, federal funds 
sold and short term investments.  Interest income increased $33.3 million during 2005 from that earned in 2004, 
totaling $103.2 million in 2005 compared to $70.0 million in the previous year.  The increase is primarily due to the 
growth in earning assets and a higher interest rate environment during 2005 when compared to 2004.  Reflecting the 
higher interest rates, the yield on average earning assets increased from 5.32% recorded in 2004 to 6.40% in 2005.   

The growth in interest income is primarily attributable to an increase in earning assets and an increase in earning 
asset yields.  During 2005, average earning assets increased $298.9 million, increasing from $1,314.5 million in 
2004 to $1,613.4 million during 2005.  Growth in average total loans and leases, totaling $255.0 million, comprised 
85.3% of the increase in average earning assets during 2005.  Interest income generated from the loan and lease 
portfolio increased $30.9 million during 2005 over the level earned in 2004, comprised of an increase of $15.1 
million from the growth in the loan and lease portfolio and an increase of $15.8 million due to the increase in the 
yield earned on the loan and lease portfolio to 6.54% from 5.33%.  The increase in the loan and lease portfolio yield 
is primarily due to a higher interest rate environment during 2005 than in 2004. 

Growth in the securities portfolio, partially offset by a slightly lower yield, also added to the increase in interest 
income during 2005 over that of 2004.  Average securities increased by $41.7 million in 2005, increasing from 
$130.4 million in 2004 to $172.1 million in 2005.  The growth equated to an increase in interest income of $2.2 
million, while a decrease in the yield earned on the securities portfolio from 5.45% to 5.40% reduced interest income 
by $0.1 million.  Interest income earned on federal funds sold increased by $0.2 million due to a small increase in the 
average balance and a higher yield during 2005. 

Interest expense is primarily generated from interest-bearing deposits, and to a lesser degree from repurchase 
agreements, FHLB advances and subordinated debentures.  Interest expense increased $20.2 million during 2005 
from that expensed in 2004, totaling $46.8 million in 2005 compared to $26.6 million in the previous year.  The 
increase in interest expense is primarily attributable to the impact of an increase in interest-bearing liabilities and a 
higher interest rate environment during 2005 when compared to 2004.  Interest-bearing liabilities averaged $1,429.2 
million during 2005, or $282.7 million higher than the average interest-bearing liabilities of $1,146.5 million during 
2004.  This growth resulted in increased interest expense of $8.5 million.  An increase in interest expense of $11.7 
million was recorded during 2005 primarily due to a higher interest rate environment during 2005 than in 2004.  The 
cost of average interest-bearing liabilities increased from the 2.32% recorded in 2004 to 3.28% in 2005.

Growth in average certificates of deposits, totaling $255.6 million, comprised 90.4% of the increase in average 
interest-bearing liabilities between 2005 and 2004.  Average FHLB advances increased $18.2 million, or 6.4% of the 
increase in average interest-bearing liabilities in 2005.  The certificate of deposit growth during 2005 equated to an 
increase in interest expense of $7.2 million, with an additional $9.1 million expensed due to the increase in the 
average rate paid as lower-rate certificates of deposit matured and were either renewed or replaced with higher-
costing certificates of deposit during most of 2005.   FHLB advance growth during 2005 equated to an increase in 
interest expense of $0.4 million, with an increased average rate adding an additional $1.3 million to interest expense.   

A decline in average savings deposits, totaling $22.3 million, equated to a decrease in interest expense of $0.5 
million; however, interest expense of $0.9 million was recorded due to an increase in the average rate paid during 
2005.   Growth in average interest-bearing checking accounts of $3.3 million equated to a less than $0.1 million 
increase in interest expense, with an additional $0.2 million of interest expense recorded due to a higher average rate 
paid during 2005.  Average short term borrowings, comprised of repurchase agreements and federal funds 
purchased, increased $11.0 million during 2005, resulting in increased interest expense of $0.2 million, with an 
additional interest expense of $0.7 million recorded due to an increase in the average rate paid during 2005. 

Growth of $16.1 million in average long-term borrowings, comprised primarily of subordinated debentures but also 
including deferred director and officer compensation programs, equated to an increase in interest expense of $1.0 
million during 2005; however, a decline in the average rate paid on subordinated debentures resulting from the 
September 2004 refinance, equated to a $0.5 million reduction of interest expense during 2005. 

Provision for Loan and Lease Losses 
The provision for loan and lease losses totaled $3.8 million during 2005, compared to the $4.7 million expensed 
during 2004.  The decline primarily reflects lower loan and lease loan growth and a decline in the volume of loan 
and lease net charge-offs during 2005 when compared to 2004.  The allowance as a percentage of total loans 
outstanding as of December 31, 2005 was 1.31%, compared to 1.35% at year-end 2004.  Loan and lease growth 
during 2005 equaled $244.7 million, compared to loan and lease growth of $281.2 million during 2004.  Net loan 
and lease charge-offs during 2005 totaled $1.1 million, or 0.08% of average total loans and leases.  Net loan and 
lease charge-offs during 2004 totaled $1.2 million, or 0.10% of average total loans and leases.    

In each accounting period, we adjust the allowance by the amount we believe is necessary to maintain the allowance 
at adequate levels.  Through the loan and lease review and credit departments, we attempt to allocate specific 
portions of the allowance based on specifically identifiable problem loans and leases.  The evaluation of the 
allowance is further based on, but not limited to, consideration of the internally prepared Reserve Analysis, 
composition of the loan and lease portfolio, third party analysis of the loan and lease administration processes and 
portfolio and general economic conditions.  In addition, the strong commercial loan and leases growth is taken into 
account.   

The Reserve Analysis, used since our inception and completed monthly, applies reserve allocation factors to

Noninterest Income 
Noninterest income totaled $5.7 million in 2005, an increase of $1.4 million from the $4.3 million earned in 2004.  
Deposit and repurchase agreement service charges increased $0.1 million in 2005, primarily reflecting the growth in 
the number of deposit accounts and modest increases in the deposit fee structure.  The cash surrender value of bank 
owned life insurance policies increased $0.3 million in 2005, primarily reflecting a higher balance from the purchase 
of additional policies during the year.  Primarily reflecting an increase in volume of activity, residential mortgage 
banking fees increased $0.2 million during 2005.  Other noninterest income includes a gain of $0.7 million which 
was recognized during 2005 from the sale of state tax credits derived from the construction of the new main office in 
downtown Grand Rapids. 

Noninterest Expense 
Noninterest expense during 2005 totaled $31.1million, an increase of $7.9 million over the $23.2 million expensed 
in 2004.  Noninterest expense during 2004 includes an $845,000 write-off associated with the unamortized balance 
of issuance costs related to the redemption of the $16.0 million of 9.60% Cumulative Preferred Securities issued in 
1999 by the MBWM Capital Trust I.  Excluding this one-time write-off, noninterest expense during 2004 totaled 
$22.4 million, with the growth in overhead costs during 2005 equating to $8.7 million. 

Of the $8.7 million growth in overhead costs, $4.7 million (54.0% of total) was in salaries and benefits, which 
primarily reflects the increase in full-time equivalent employees from 194 at year-end 2004 to 273 at year-end 2005 
and annual pay increases.  Occupancy, furniture and equipment costs increased $1.6 million (18.4% of total) in 2005, 
primarily reflecting the opening of our Holland banking office in October of 2004, the opening of our new main 
office in downtown Grand Rapids during the second quarter of 2005, the opening of our new leased facilities in 
Lansing and Ann Arbor during the third quarter of 2005 and our increased staffing level. 

While the dollar amount of noninterest costs has increased, the growth of net interest income and fee income has 
increased more.  Noninterest costs during 2005 were $8.7 million higher than the level of overhead costs expensed 
during 2004; however, net interest income and fee income increased a combined $14.2 million during the same time 
period.  Monitoring and controlling our noninterest costs, while at the same time providing high quality service to 
our customers, is one of our priorities.  The efficiency ratio, a banking industry standardized calculation that attempts 
to reflect the utilization of overhead costs, declined during 2004 but remained well below banking industry averages.  
Computed by dividing noninterest expenses by net interest income plus noninterest income, the efficiency ratio was 
51.1% during 2005, compared to 49.6% during 2004.  If the one-time write-off addressed above is excluded from the 
calculation, our 2004 efficiency ratio improves to 47.8%.  The decline in the efficiency ratio is primarily related to 
the initial overhead costs associated with our expansion into Lansing and Ann Arbor, especially salary and benefit 
and occupancy expenses. 

Federal Income Tax Expense 
Federal income tax expense was $8.1 million in 2005, an increase of $3.0 million over the $5.1 million expensed 
during 2004.  The increase during 2005 is primarily due to the growth in our pre-federal income tax profitability and 
an increase in the effective tax rate, the latter of which reflects a lower level of tax-exempt income as a percent of 
total income. 

CAPITAL RESOURCES 

Shareholders’ equity is a noninterest-bearing source of funds that provides support for our asset growth.  
Shareholders’ equity was $171.9 million and $155.1 million at December 31, 2006 and 2005, respectively.  The 
$16.8 million increase during 2006 is primarily attributable to net income from operations.  Net income from 
operations totaled $19.8 million during 2006.  Also positively impacting shareholders’ equity was a $0.3 million 
mark-to-market adjustment for available for sale securities as defined in SFAS No. 115, plus proceeds totaling $0.4 
million relating to stock option exercises and our dividend reinvestment and employee stock purchase plans. 
Negatively impacting shareholders’ equity during 2006 was the payment of cash dividends, which totaled $4.0 
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.  Our and our bank’s capital ratios as of December 31, 2006 and 2005 are disclosed under 
Note 16 on pages F-55 and F-56 of the Notes to Consolidated Financial Statements. 

Our ability to pay cash and stock dividends is subject to limitations under various laws and regulations and to 
prudent and sound banking practices.  On April 11, 2006, we declared a 5% common stock dividend, payable on 
May 16, 2006 to record holders as of April 24, 2006.  This represented the sixth consecutive year we have paid a 5% 
stock dividend.  Also during 2006, we paid a cash dividend on our common stock each calendar quarter.  These cash 
dividends totaled $0.51 per share for 2006, and $4.0 million in aggregate amount.  On January 9, 2007, we declared 
a $0.14 per common share cash dividend that will be paid on March 9, 2007 to shareholders of record on February 9, 
2007. 

LIQUIDITY 

Liquidity is measured by our ability to raise funds through deposits, borrowed funds, capital or cash flow from the 
repayment of loans and investment securities.  These funds are used to meet deposit withdrawals, maintain reserve 
requirements, fund loans and operate our company.  Liquidity is primarily achieved through the growth of deposits 
(both local and out-of-area) and liquid assets such as securities available for sale, matured securities, and federal 
funds sold.  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. 

Our liquidity strategy is to fund loan growth with deposits, repurchase agreements and other borrowed funds and to 
maintain an adequate level of short- and medium-term investments to meet typical daily loan and deposit activity.  
Net deposit and repurchase agreement growth from customers located in our market areas increased by $189.8 
million, or 35.9%, during 2006.  This strong growth was not fully sufficient to meet the earning asset growth of 
$204.2 million.  To assist in providing the additional needed funds, we regularly obtained certificates of deposit from 
customers outside of our market areas.  As of December 31, 2006, out-of-area deposits totaled $1,013.8 million, an 
increase in dollar volume of $51.0 million from the $962.8 million outstanding at December 31, 2005.  However, as 
a percent of combined total deposits and repurchase agreements, out-of-area deposits declined from 64.6% as of 
December 31, 2005 to 58.5% at December 31, 2006. 

As a member of the Federal Home Loan Bank of Indianapolis, our bank has access to the FHLB advance borrowing 
programs.  As of December 31, 2006, advances totaled $95.0 million, compared to $130.0 million outstanding as of 
December 31, 2005.  Our borrowing line of credit at December 31, 2006 totaled $322.6 million, with availability of 
$216.5 million. 

We have the ability to borrow money on a daily basis through correspondent banks using established federal funds 
purchased lines.  During 2006, our federal funds purchased position averaged $3.7 million, compared to an average 
federal funds sold position of $9.7 million.  At December 31, 2006, our established unsecured federal funds 
purchased lines totaled $72.0 million.

In addition to normal loan funding and deposit flow, we also need to maintain liquidity to meet the demands of 
certain unfunded loan commitments and standby letters of credit.  At December 31, 2006, we had a total of $451.1 
million in unfunded loan commitments and $73.2 million in unfunded standby letters of credit.  Of the total unfunded 
loan commitments, $390.2 million were commitments available as lines of credit to be drawn at any time as 
customers’ cash needs vary, and $60.9 million were for loan commitments scheduled to close and become funded 
within the next twelve months.  We monitor fluctuations in loan balances and commitment levels, and include such 
data in our overall liquidity management.

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.

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.

the next twelve months.  The following table reflects the suggested impact on net interest income over the next 
twelve months, which is well within our policy parameters established to manage and monitor interest rate risk.

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; economic and competitive conditions; potential changes in lending, investing, and deposit 
gathering strategies; client preferences; and other factors.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 

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

We have audited the accompanying consolidated balance sheets of Mercantile Bank Corporation as of December 31, 
2006 and 2005, and the related consolidated statements of income, changes in shareholders' equity and cash flows for 
each of the three years in the period ended December 31, 2006.  These financial statements are the responsibility of 
Mercantile’s management.  Our responsibility is to express an opinion on these financial statements based on our 
audits. 

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board 
(United States).  Those standards require that we plan and perform the audit to obtain reasonable assurance about 
whether the financial statements are free of material misstatement.  An audit includes examining, on a test basis, 
evidence supporting the amounts and disclosures in the financial statements.  An audit also includes assessing the 
accounting principles used and significant estimates made by management, as well as evaluating the overall financial 
statement presentation.  We believe that our audits provide a reasonable basis for our opinion. 

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the 
financial position of Mercantile Bank Corporation as of December 31, 2006 and 2005, and the results of its 
operations and its cash flows for each of the three years in the period ended December 31, 2006 in conformity with 
U.S. generally accepted accounting principles. 

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United 
States), the effectiveness of Mercantile Bank Corporation’s internal control over financial reporting as of December 
31, 2006, based on criteria established in Internal Control – Integrated Framework issued by the Committee of 
Sponsoring Organizations of the Treadway Commission (COSO) and our report dated February 20, 2007 expressed 
an unqualified opinion thereon.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 

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

We have audited management’s assessment, included in the accompanying Management’s Report on Internal Control 
Over Financial Reporting, that Mercantile Bank Corporation maintained effective internal control over financial 
reporting as of December 31, 2006, based on criteria established in Internal Control – Integrated Framework issued 
by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).  Mercantile Bank 
Corporation’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.  Our responsibility is to express an 
opinion on management’s assessment and an opinion on the effectiveness of the company’s internal control over 
financial reporting based on our audit. 

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board 
(United States).  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, evaluating management’s 
assessment, testing and evaluating the design and operating effectiveness of internal control, and performing such 
other procedures as we considered necessary in the circumstances.  We believe that our audit provides a reasonable 
basis for our opinion. 

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.   

In our opinion, management’s assessment that Mercantile Bank Corporation maintained effective internal control 
over financial reporting as of December 31, 2006, is fairly stated, in all material respects, based on criteria 
established in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the 
Treadway Commission (COSO).  Also in our opinion, Mercantile Bank Corporation maintained, in all material 
respects, effective internal control over financial reporting as of December 31, 2006, based on criteria established in 
Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway 
Commission (COSO).   

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United 
States), the consolidated financial statements of Mercantile Bank Corporation and our report dated February 20, 
2007 expressed an unqualified opinion on those consolidated financial statements.

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 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 systems of internal control over financial reporting presented in conformity 
with generally accepted principles as of December 31, 2006.  This assessment was based on criteria for effective 
internal control over financial reporting described in Internal Control – Integrated Framework issued by the 
Committee of Sponsoring Organizations of the Treadway Commission.  Based on this assessment, management 
believes that, as of December 31, 2006, Mercantile Bank Corporation maintained effective control over financial 
reporting presented in conformity with generally accepted accounting principles based on those criteria. 

The Company’s independent auditors have issued an audit report on our assessment of the Company’s internal 
control over financial reporting.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

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 
Mortgage Company, LLC (“Mortgage Company”), 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. 

We formed a business trust, Mercantile Bank Capital Trust I (“the trust”), in 2004 to issue trust preferred securities.  
We issued subordinated debentures to the trust in return for the proceeds raised from the issuance of the trust 
preferred securities.  In accordance with FASB Interpretation No. 46, the trust is not consolidated, but instead we 
report the subordinated debentures issued to the trust as a liability. 

Nature of Operations:  Mercantile was incorporated on July 15, 1997 to establish and own the Bank based in Grand 
Rapids, Michigan.  The Bank is a community-based financial institution.  The Bank began operations on 
December 15, 1997.  The Bank’s primary deposit products are checking, savings, and term certificate accounts, and 
its primary lending products are commercial loans, commercial leases, residential mortgage loans, and instalment 
loans.  Substantially all loans and leases are secured by specific items of collateral including business assets, real 
estate or consumer assets.  Commercial loans and leases 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 are 
primarily with customers located in the Grand Rapids, Holland, Lansing and Ann Arbor metropolitan areas.  The 
Bank’s retail deposits are also from customers located within those areas.  As an alternative source of funds, the 
Bank has also issued certificates to depositors outside of the Bank’s primary market areas.  Substantially all revenues 
are derived from banking products and services and investment securities. 

Mercantile Bank Mortgage Company was formed during 2000.  A subsidiary of the Bank, Mercantile Bank 
Mortgage Company was established to increase the profitability and efficiency of the mortgage loan operations.  
Mercantile Bank Mortgage Company initiated business on October 24, 2000 via the Bank’s contribution of most of 
its residential mortgage loan portfolio and participation interests in certain commercial mortgage loans.  On the same 
date, the Bank also transferred its residential mortgage origination function to Mercantile Bank Mortgage Company.  
On January 1, 2004, Mercantile Bank Mortgage Company was reorganized as Mercantile Bank Mortgage Company, 
LLC, a limited liability company, which is 99% owned by the Bank and 1% owned by Mercantile Insurance.  
Mortgage loans originated and held by the Mercantile Bank Mortgage Company are serviced by the Bank pursuant 
to a servicing agreement.   

Mercantile Insurance was formed during 2002 through the acquisition of an existing shelf insurance agency.  
Insurance products are offered through an Agency and Institutions Agreement among Mercantile Insurance, the Bank 
and Hub International.  The insurance products are marketed through a central facility operated by the Michigan 
Bankers Insurance Association, members of which include the insurance subsidiaries of various Michigan-based 
financial institutions and Hub International.  Mercantile Insurance receives commissions based upon written 
premiums produced under the Agency and Institutions Agreement. 

Mercantile Real Estate was organized on July 21, 2003, principally to develop, construct, and own a new 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. 

Mercantile filed an election to become a financial holding company pursuant to Title I of the Gramm-Leach-Bliley 
Act and implementing Federal Reserve Board regulations effective March 23, 2000.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 
December 31, 2006 and 2005 

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) 

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 
future results could differ.  The allowance for loan and lease 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-bearing 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.  Other securities such as Federal Home Loan Bank stock are carried at cost. 

Interest income includes amortization of purchase premiums and discounts.  Premiums and discounts on securities 
are amortized 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 trade date and determined using the 
specific identification method. 

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, management considers: (1) the length of time and extent that fair value 
has been less than cost, (2) the financial condition and near term prospects of the issuer, and (3) our ability and intent 
to hold the security for a period sufficient to allow for any anticipated recovery in fair value. 

Loans and Leases:  Loans and leases that management has the intent and ability to hold for the foreseeable future or 
until maturity or payoff are reported at the principal balance outstanding, net of unearned interest, deferred loan fees 
and costs and an allowance for loan and lease 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.   

Interest income on commercial loans and leases 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 120 days past due.  Past due status is based on the contractual terms of the loan or lease.  In 
all cases, loans and leases 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 and leases placed on nonaccrual is reversed against interest income.  
Interest received on such loans and leases is accounted for on the cash-basis or cost-recovery method, until 
qualifying for return to accrual.  Loans and leases 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 market, as determined by outstanding commitments from investors.  Net unrealized losses, 
if any, are recorded as a valuation allowance and charged to earnings.  Such loans are sold service released.  
Residential mortgage banking fees include fees on direct brokered mortgage loans and the net gain on sale of 
mortgage loans originated for sale.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 
December 31, 2006 and 2005 

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) 

Allowance for Loan and Lease Losses:  The allowance for loan and lease losses is a valuation allowance for probable 
incurred credit losses.  Loan and lease losses are charged against the allowance when management believes the 
uncollectibility of a loan or lease balance is confirmed.  Subsequent recoveries, if any, are credited to the allowance.  
Management estimates the allowance balance required using past loan and lease loss experience, the nature and 
volume of the portfolio, information about specific borrower situations and estimated collateral values, and economic 
conditions and other factors.  Allocations of the allowance may be made for specific loans and leases, but the entire 
allowance is available for any loan or lease that, in management’s judgment, should be charged-off. 

A loan or lease 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 by management in determining impairment include payment status, collateral 
value and the probability of collecting scheduled principal and interest payments when due.  Loans that experience 
insignificant payment delays and payment shortfalls generally are not classified as impaired.  Management 
determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into 
consideration all of the circumstances surrounding the loan or lease and the borrower, including the length of delay, 
the reasons for the 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 loans and leases and 
construction loans by either 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.  We do not separately identify 
individual residential and consumer loans for impairment disclosures. 

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 corporation, (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 corporation does not maintain 
effective control over the transferred assets through an agreement to repurchase them before their maturity. 

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

Foreclosed Assets:  Assets acquired through or instead of foreclosure are initially recorded at fair value when 
acquired, establishing a new cost basis.  If fair value declines, a valuation allowance is recorded through expense.  
Costs after acquisition are expensed. 

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. 

Repurchase Agreements:  Substantially all repurchase agreement liabilities represent amounts advanced by various 
customers.  Securities are pledged to cover these liabilities, which are not covered by federal deposit insurance.

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) 

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 in accordance with FASB Interpretation No. 45, are recorded at fair value. 

Stock Compensation:  Statement of Financial Accounting Standards (“SFAS”) no. 123(R), Share-based Payment, 
using the modified prospective transition method, was adopted effective January 1, 2006.  Accordingly, stock-based 
employee compensation cost was recorded starting in 2006 using the fair value method.  For 2006, adopting this 
standard resulted in a reduction in net income before taxes and net income of $242,000 and a decrease in basic and 
diluted earnings per share of $0.03. 

Prior to January 1, 2006, employee compensation expense under stock options was reported using the intrinsic value 
method; therefore, no stock-based compensation cost is reflected in net income for the years ending December 31, 
2005 and 2004, as all options granted had an exercise price equal to or greater than the market price of the 
underlying common stock at date of grant. 

The following table illustrates the effect on net income and earnings per share if expense was measured using the fair 
value recognition provisions of FASB Statement No. 123, Accounting for Stock-Based Compensation, for the years 
ending December 31.

Income Taxes:  Income tax expense is the total of the current year income tax due or refundable and the change in 
deferred tax assets and liabilities.  Deferred tax assets and liabilities are the expected future tax amounts for the 
temporary differences between the carrying amounts and tax bases of assets and liabilities, computed using enacted 
tax rates.  A valuation allowance, if needed, reduces deferred 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, as more fully disclosed separately.  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 weighted average common shares outstanding during the 
period.  Diluted earnings per share include the dilutive effect of additional potential common shares issuable under 
stock options.  Earnings per share are restated for all stock dividends, including the 5% stock dividends paid on May 
16, 2006, August 1, 2005 and May 3, 2004.  The fair value of shares issued in stock dividends is transferred from 
retained earnings to common stock to the extent of available retained earnings. 

Comprehensive Income:  Comprehensive income consists of net income and other comprehensive income.  Other 
comprehensive income includes unrealized gains and losses on securities available for sale which are also recognized 
as separate components of equity.  

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 now are such matters that would have a material effect on the financial 
statements. 

Reclassifications:  Some items in the prior year financial statements were reclassified to conform to the current 
presentation. 

Operating Segments:  While we monitor the revenue streams of the various products and services offered, the 
identifiable segments are not material and operations are managed and financial performance is evaluated on a 
company-wide basis.  Accordingly, all of our financial service operations are aggregated in one reportable operating 
segment. 

Adoption of New Accounting Standards:  In September 2006, the Securities and Exchange Commission (“SEC”) 
released Staff Accounting Bulletin No. 108, Considering the Effects of Prior Year Misstatements when Quantifying 
Misstatements in Current Year Financial Statements (“SAB 108”), which is effective for fiscal years ending on or 
after November 15, 2006.  SAB 108 provides guidance on how the effects of prior-year uncorrected financial 
statement misstatements should be considered in quantifying a current year misstatement.  SAB 108 requires public 
companies to quantify misstatements using both an income statement (rollover) and balance sheet (iron curtain) 
approach and evaluate whether either approach results in a misstatement that, when all relevant quantitative and 
qualitative factors are considered, is material.  If prior year errors that had been previously considered immaterial 
now are considered material based on either approach, no restatement is required so long as management properly 
applied its previous approach and all relevant facts and circumstances were considered.  Adjustments considered 
immaterial in prior years under the method previously used, but now considered material under the dual approach 
required by SAB 108, are to be recorded upon initial adoption of SAB 108.  The amount so recorded, if any, is 
shown as a cumulative effect adjustment recorded in opening retained earnings as of January 1, 2006.  The adoption 
of SAB 108 had no effect on the financial statements for the year ending December 31, 2006. 

In July 2006, the FASB issued Interpretation No. 48, Accounting for Uncertainty in Income Taxes – an 
interpretation of FASB Statement No. 109 (“FIN 48”), which prescribes a recognition threshold and measurement 
attribute for a tax position taken or expected to be taken in a tax return.  FIN 48 also provides guidance on 
derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition.  FIN 48 
is effective for fiscal years beginning after December 15, 2006.  We have determined that the adoption of FIN 48 
will not have a material effect on the financial statements.

Effect of Newly Issued But Not Yet Effective Accounting Standards:  New accounting standards have been issued 
that we do not expect will have a material effect on the financial statements when adopted in future years or for 
which we have not yet completed its evaluation of the potential effect upon adoption.  In general, these standards 
revise accounting for derivatives embedded in other financial instruments for 2007, revise the recognition and 
accounting for servicing of financial assets for 2007, establish a hierarchy about the assumptions used to measure fair 
value for 2008, revise the accrual of post-retirement benefits associated with providing life insurance for 2008 and 
revise the accounting for cash surrender value for 2007.

We evaluate securities for other-than-temporary impairment at least on a quarterly basis, and more frequently when 
economic or market concerns warrant such evaluation.  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.  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, 2006, $117.7 million in debt securities and a mutual fund have unrealized losses with aggregate 
depreciation of 1.1% from the amortized cost basis of total securities.  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 an increasing interest rate environment.  As we have the 
ability to hold debt securities until maturity, or for the foreseeable future if classified as available for sale, no 
declines are deemed to be other than temporary.

The amortized cost and fair values of debt securities at year-end 2006, by contractual maturity, are shown below.  
The contractual maturity is utilized below 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. 

The maturities of securities and their weighted average yields at December 31, 2006 are shown in the following

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 the Bank and are 
primarily held in safekeeping by correspondent banks.  Repurchase agreements are offered principally to certain 
large deposit customers as uninsured deposit equivalent investments.  Repurchase agreements were secured by 
securities with a market value of $91.2 million and $80.7 million at year-end 2006 and 2005, respectively.

NOTE 9 – STOCK-BASED COMPENSATION 

Stock-based compensation plans are used to provide directors and employees with an increased incentive to 
contribute to the long-term performance and growth of Mercantile, to join the interests of directors and employees 
with the interests of Mercantile’s shareholders through the opportunity for increased stock ownership and to attract 
and retain directors and employees.  From 1997 through 2005, stock option grants were provided to directors and 
certain employees through several stock option plans, including the 1997 Employee Stock Option Plan, 2000 
Employee Stock Option Plan, 2004 Employee Stock Option Plan and Independent Director Stock Option Plan.  
During 2006, stock option and restricted stock grants were provided to certain employees through the Stock 
Incentive Plan of 2006. 

Under our 1997 Employee Stock Option Plan, 2000 Employee Stock Option Plan and 2004 Employee Stock Option 
Plan, stock options granted to employees were granted at the market price on the date of grant, generally fully vest 
after one year and expire ten years from the date of grant.  Stock options granted to non-executive officers during 
2005 vested about three weeks after being granted.  Under our Independent Director Stock Option Plan, stock 
options granted to non-employee directors are at 125% of the market price on the date of grant, fully vest after five 
years and expire ten years from the date of grant.  The Stock Incentive Plan of 2006, approved by our shareholders at 
the annual meeting on April 27, 2006, replaced all of our outstanding stock option plans for stock options not 
previously granted.  Under the Stock Incentive Plan of 2006, 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 Mercantile stock on the 
day before the date of grant, with price, vesting and expiration date parameters determined by Mercantile’s 
Compensation Committee on a grant-by-grant basis.  Generally, the stock options granted to employees during 2006 
fully vest after two years and expire after seven years.  The restricted stock awards granted to certain employees 
during 2006, totaling 20,190 shares and having a fair value per share of $39.84, fully vest after four years.  No 
payments were required from employees for the restricted stock awards.  At year-end 2006, there were 550,884 
shares authorized for future incentive awards. 

As of December 31, 2006, there was $300,000 of total unrecognized compensation cost related to unvested stock 
options granted under our various stock-based compensation plans.  The compensation cost is expected to be 
recognized over a weighted-average period of 1.5 years.  As of December 31, 2006, there was $690,000 of total 
unrecognized compensation cost related to unvested restricted stock granted under our Stock Incentive Plan of 2006.  
The compensation cost is expected to be recognized over a period of 3.9 years.

NOTE 9 – STOCK-BASED COMPENSATION (Continued) 

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 was determined using the following weighted-average assumptions as of grant 
date.

NOTE 11 – 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 the 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.

NOTE 11 – COMMITMENTS AND OFF-BALANCE-SHEET RISK  (Continued) 

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, 
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.  The 
balance of the liability account related to loan commitments was $0.5 million at year-end 2006 and 2005. 

At year-end 2006 and 2005, 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 
Standby letters 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 prime rate.  For term debt secured by real estate, customers are generally offered a floating 
rate tied to the prime rate and a fixed rate currently ranging from 7.25% to 8.25%.  These credit facilities generally 
balloon within five years, with payments based on amortizations ranging from 10 to 25 years.  For term debt secured 
by non-real estate collateral, customers are generally offered a floating rate tied to the prime rate and a fixed rate 
currently ranging from 7.25% to 8.25%.  These credit facilities generally mature and fully amortize within five years.

NOTE 12 – BENEFIT PLANS 

We have a 401(k) benefit plan that covers substantially all of our employees.  Our 2006, 2005 and 2004 matching 
401(k) contribution charged to expense was $674,000, $554,000 and $413,000, respectively.  The percent of our 
matching contributions to the 401(k) is determined annually by the Board of Directors.  The 401(k) benefit plan 
allows employee contributions up to 15% of their compensation, which are matched at 100% of the first 5% of the 
compensation contributed.  Matching contributions are immediately vested. 

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 only upon termination of service as a 
director.  The deferred amounts are categorized on our financial statements as other borrowed money.  The deferred 
balances are paid interest at a rate equal to the prime rate, adjusted at the beginning of each calendar quarter.  
Interest expense for the plan during 2006, 2005 and 2004 was $81,000, $43,000 and $21,000, respectively. 

We have a non-qualified deferred compensation program in which selected officers may defer all or portions of 
salary and bonus payments.  The deferred amounts are categorized on our financial statements as other borrowed 
money.  The deferred balances are paid interest at a rate equal to the prime rate, adjusted at the beginning of each 
calendar quarter.  Interest expense for the plan during 2006, 2005 and 2004 was $148,000, $79,000 and $38,000, 
respectively. 

The Mercantile Bank Corporation Employee Stock Purchase Plan of 2002 (“Stock Purchase Plan”) 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 average, rounded to the nearest whole cent, of the highest and 
lowest sales prices of our common stock reported on The Nasdaq Stock Market.  Originally, 25,000 shares of 
common stock may be issued under the Stock Purchase Plan; however, the number of shares has been and may 
continue to be adjusted in the future to reflect stock dividends and other changes in our capitalization.  The numbers 
of shares issued under the Stock Purchase Plan totaled 2,774 and 2,491 in 2006 and 2005, respectively.  As of 
December 31, 2006, there were 20,820 shares available under the Stock Purchase Plan.

Carrying amount is the estimated fair value for cash and cash equivalents, Federal Home Loan Bank stock, accrued 
interest receivable and payable, bank owned life insurance policies, demand deposits, securities sold under 
agreements to repurchase, and variable rate loans or 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 or deposits and for variable rate loans or 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.  Fair value of subordinated debentures and Federal Home Loan Bank 
advances is based on current rates for similar financing.  Fair value of off balance sheet items is estimated to be

NOTE 15 – SUBORDINATED DEBENTURES 

Mercantile Trust, a business trust formed by the company, was incorporated in 2004 for the purpose of issuing Series 
A and Series B Preferred Securities.  On September 16, 2004, Mercantile Trust sold the Series A Preferred 
Securities in a private sale for $16.0 million, and also sold $495,000 of Series A Common Securities to Mercantile.  
The proceeds of the Series A Preferred Securities and the Series A Common Securities were used by Mercantile 
Trust to purchase $16,495,000 of Series A Floating Rate Notes that were issued by Mercantile on September 16, 
2004.  Mercantile used the proceeds of the Series A Floating Rate Notes to finance the redemption on September 17, 
2004 of the $16.0 million of 9.60% Cumulative Preferred Securities issued in 1999 by MBWM Capital Trust I.  On 
December 10, 2004, Mercantile Trust sold the Series B Preferred Securities in a private sale for $16.0 million, and 
also sold $495,000 of Series B Common Securities to Mercantile.  The proceeds of the Series B Preferred Securities 
and the Series B Common Securities were used by Mercantile Trust to purchase $16,495,000 of Series B Floating 
Rate Notes that were issued by Mercantile on December 10, 2004.  Substantially all of the net proceeds of the Series 
B Floating Rate Notes were contributed to our bank as capital to provide support for asset growth, fund investments 
in loans and securities and for general corporate purposes. 

The only significant assets of Mercantile Trust are the Series A and Series B Floating Rate Notes, and the only 
significant liabilities of Mercantile Trust are the Series A and Series B Preferred Securities.  The Series A and Series 
B Floating Rate Notes are categorized on our consolidated balance sheet as subordinated debentures and the interest 
expense is recorded on our consolidated statement of income under interest expense on long-term borrowings.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 
December 31, 2006 and 2005 

NOTE 16 - REGULATORY MATTERS 

Mercantile and the Bank 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. 

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 adequately 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 being 
closely monitored 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 in 
the discretion of the federal regulator.  At year-end 2006 and 2005, the most recent regulatory notifications 
categorized the Bank as well capitalized under the regulatory framework for prompt corrective action.  There are no 
conditions or events since that notification that we believe has changed the Bank’s category. 

At year end, actual capital levels (in thousands) and minimum required levels for Mercantile and the Bank were:

Federal and state banking laws and regulations place certain restrictions on the amount of dividends the Bank can 
transfer to Mercantile and on the capital levels that must be maintained.  At year-end 2006, under the most restrictive 
of these regulations (to remain well capitalized), the Bank could distribute approximately $22.5 million to Mercantile 
as dividends without prior regulatory approval. 

The capital levels as of year-end 2006 and 2005 include $32.0 million of trust preferred securities issued by 
Mercantile Trust in September 2004 and December 2004 subject to certain limitations.  Federal Reserve guidelines 
limit the amount of trust preferred securities which can be included in Tier 1 capital of Mercantile to 25% of total 
Tier 1 capital.  At year-end 2006 and 2005, all $32.0 million of the trust preferred securities were included as Tier 1 
capital of Mercantile.

Quality, Not Quantity

“To a lot of banks, service is simply

having a branch on every corner,”

says Mike Sankey. “It has nothing to 

Mike Sankey
Controller
Grand Rapids

do with the customer experience

inside those branches.”   

Mercantile has a limited 

number of branches, so the 

emphasis is on the quality of the

customer interaction. “We don’t

have to hire anybody that comes

along just to fill our buildings.

We take our time to get the very

best people. Then we empower

them to do whatever it takes to

®

please customers.”
