Safe Harbor Statement Under the Private Securities Litigation Reform Act of 1995
Some of the information in this report contains “forward-looking statements” within the meaning of and intended to
be covered by the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. Forward-looking
statements typically are identified with use of terms such as “may,” “might,” “will, “should,” “expect,” “plan,”
“anticipate,” “believe,” “estimate,” “predict,” “potential,” “could,” “continue” and the negative of these terms and
similar words, although some forward-looking statements may be expressed differently. Forward-looking statements
also include, but are not limited to, statements regarding plans, objectives, expectations or consequences of announced
transactions, and statements about future performance, operations, products and services. The ability to predict results
or the actual effect of future plans or strategies is inherently uncertain. You should be aware that actual results could
differ materially from those contained in the forward-looking statements due to a number of factors, including, but
not limited to: the ability to efficiently integrate acquisitions into our operations, retain the customers of these businesses
and grow the acquired operations; credit risk; changes in the appraised valuation of real estate securing impaired
loans;  outcomes  of  litigation  and  other  contingencies;  exposure  to  general  and  local  economic  conditions;  risks
associated with rapid increases or decreases in prevailing interest rates; consolidation within the banking industry;
competition from banks and other financial institutions; the ability to attract and retain relationship officers and other
key  personnel;  burdens  imposed  by  federal  and  state  regulation;  changes  in  regulatory  requirements;  changes  in
accounting regulation or standards applicable to banks; and other risks discussed under the caption “Risk Factors”
in Item 1A of this Form 10-K, all of which could cause actual results to differ from those set forth in the forward-
looking statements.

Readers are cautioned not to place undue reliance on forward-looking statements, which reflect management's analysis
and expectations only as of the date of such statements. Forward-looking statements speak only as of the date they are
made, and the Company does not intend, and undertakes no obligation, to publicly revise or update forward-looking
statements after the date of this report, whether as a result of new information, future events or otherwise, except as
required by federal securities law. You should understand that it is not possible to predict or identify all risk factors.
Readers should carefully review all disclosures we file from time to time with the Securities and Exchange Commission
which are available on the Company's website at www.enterprisebank.com under "Investor Relations."

PART 1
ITEM 1: BUSINESS

General
Enterprise Financial Services Corp (“we” or the “Company” or “Enterprise”), a Delaware corporation, is a financial
holding company headquartered in Clayton, Missouri incorporated in December 1994. We are the holding company
for Enterprise Bank & Trust (the “Bank”), a full service financial institution offering banking and wealth management
services to individuals and corporate customers largely located in the St. Louis, Kansas City, and Phoenix metropolitan
markets. Our executive offices are located at 150 North Meramec, Clayton, Missouri 63105, and our telephone number
is (314) 725-5500.

Available Information 
Various  reports  provided  to  the  Securities  and  Exchange  Commission  (the  "SEC"),  including  our  annual  reports,
quarterly  reports,  current  reports,  and  proxy  statements,  are  available  free  of  charge  on  our  website  at
www.enterprisebank.com  under  "Investor  Relations."  These  reports  are  made  available  as  soon  as  reasonably
practicable after they are electronically filed with or furnished to the SEC. Our filings with the SEC are also available
on the SEC's website at www.sec.gov.

Business Strategy
Our  stated  mission  is  “Guiding  people  to  a  lifetime  of  financial  success.” We  have  established  an  accompanying
corporate vision, “To have a company where our associates are proud, our customers find easy to navigate, our investors
value and our communities flourish.” These tenets are fundamental to our business strategies and operations.

Our business strategy is to generate shareholder returns by providing comprehensive financial services primarily to
private businesses, their owner families, and other success-minded individuals. The Company has one segment for
purposes of its financial reporting.

1

The Company offers a broad range of business and personal banking services including wealth management services.
Lending services include commercial and industrial, commercial real estate, real estate construction and development,
residential  real  estate,  and  consumer  loans. A  wide  variety  of  deposit  products  and  a  complete  suite  of  treasury
management  and  international  trade  services  complement  our  lending  capabilities. Tax  credit  brokerage  activities
consist of the acquisition of Federal and State tax credits and the sale of these tax credits to clients. Enterprise Trust,
a  division  of  the  Bank  (“Enterprise  Trust”  or  “Trust”),  provides  financial  planning,  estate  planning,  investment
management, and trust services to businesses, individuals, institutions, retirement plans, and non-profit organizations.

Key components of our strategy include a focused and relationship-oriented distribution and sales approach, with an
emphasis  on  growing  fee  income  and  niche  businesses,  while  maintaining  prudent  credit  and  interest  rate  risk
management, appropriate supporting technology, and controlled expense growth.  

Building long-term client relationships - Our growth strategy is largely client relationship driven. We continuously
seek to add clients who fit our target market of businesses, business owners, professionals, and associated relationships.
Those relationships are maintained, cultivated, and expanded over time by trained, experienced banking officers and
other professionals. We fund loan growth primarily with core deposits from our business and professional clients in
addition to consumers in our branch market areas. This is supplemented by borrowing or other deposit sources, including
advances from Federal Home Loan Bank of Des Moines (the “FHLB”), and brokered certificates of deposits.  

Fee income business - We offer a broad range of Treasury Management products and services that benefit businesses
ranging from large national clients to local merchants. Customized solutions and special product bundles are available
to clients of all sizes. Responding to ever increasing needs for data/information security and improved functional
efficiency, the Company continues to offer robust treasury systems that employ mobile technology and fraud detection/
mitigation services. Enterprise Trust offers a wide range of fiduciary, investment management, and financial advisory
services.  We  employ  attorneys,  certified  financial  planners,  estate  planning  professionals,  and  other  investment
professionals. Enterprise Trust representatives assist clients in defining lifetime goals and designing plans to achieve
them, consistent with the Company's long-term relationship strategy. The Company also offers card services including
debit cards, credit cards, and merchant services, international banking, and tax credit businesses that generate fee
income.

Specialized lending and product niches - We have focused an increasing amount of our lending activities in specialty
markets  where  we  believe  our  expertise  and  experience  as  a  commercial  lender  provides  advantages  over  other
competitors. In addition, we have developed expertise in certain product niches. These specialty niche activities focus
on the following areas: 

•

•

•

•

•

Enterprise Value Lending/Senior Debt Financing. We support mid-market company mergers and acquisitions in
many domestic markets. We market directly to targeted private equity firms and provide primarily senior debt
financing to portfolio companies.  

Life Insurance Premium Finance. We specialize in financing high-end whole life insurance premiums utilized in
high net worth estate planning, through relationships with boutique estate planners throughout the U.S. 

Tax Credit Related Lending. We are a secured lender on affordable housing projects funded through the use of
Federal and State Low Income Housing tax credits. In addition, we provide leveraged and other loans on projects
funded through the Department of the Treasury CDFI New Markets Tax Credit program. In prior years, we were
selected to distribute New Markets Tax Credits. In this capacity, we have been responsible for allocating a total
of $183 million of tax credits to clients and projects.  

Tax  Credit  Brokerage.  We  acquire  10-year  streams  of  Missouri  state  tax  credits  from  affordable  housing
development funds and sell the tax credits to clients and other individuals for tax planning purposes. 

Enterprise Aircraft Finance.  Beginning in 2016, we acquired a unit specializing in financing and leasing solutions
for the acquisition of owner-operator fixed and rotor wing aircraft.

Capitalizing on technology - Our client technology product offerings include, but are not limited to, internet banking,
mobile banking, treasury management products, remote deposit capture, check image, and statement and document

2

imaging. Additional service offerings currently supported by the Bank include controlled disbursements, repurchase
agreements,  and  sweep  investment  accounts.  Our  treasury  management  suite  of  products  blends  technology  and
personal service, which we believe often creates a competitive advantage over our competition. Technology products
are also extensively utilized within the organization by associates in all lines of business including operations and
support, customer service, and financial reporting for internal management purposes and for external compliance.

Maintaining asset quality - The Company monitors asset quality through formal, ongoing, multiple-level reviews of
loans in each market and specialized lending niche. These reviews are overseen by the Company's credit administration
department. In addition, the loan portfolio is subject to ongoing monitoring by a loan review function that reports
directly to the Credit Committee of the Bank's Board of Directors. 

Expense management - The Company manages expenses carefully through detailed budgeting and expense approval
processes.  We  measure  the  “efficiency  ratio”  as  a  benchmark  for  improvement.  The  efficiency  ratio  is  equal  to
noninterest expense divided by total revenue (net interest income plus noninterest income).

Executive leadership - In February 2017, as part of an orderly succession and transition plan, the Company announced
the resignation of Peter F. Benoist from the position of Chief Executive Officer ("CEO") and from the Company's
board of directors. Concurrent with Mr. Benoist’s resignation, the Company announced that James B. Lally would
succeed Mr. Benoist as CEO and as a member of the Board. The transition took place at the Company's 2017 annual
meeting of stockholders on May 2, 2017. 

Acquisitions and Divestitures
On February 10, 2017, the Company closed its acquisition of Jefferson County Bancshares, Inc. ("JCB"). JCB merged
with and into the Company, and Eagle Bank and Trust Company of Missouri, JCB's wholly-owned subsidiary bank,
merged with and into the Bank. As part of the acquisition, 3.3 million shares of the Company’s common stock were
issued and approximately $29.3 million in cash was paid to JCB shareholders and holders of JCB stock options. The
overall transaction had a value of approximately $171.0 million, including JCB’s common stock and stock options.
The conversion of JCB's core systems was completed late in the second quarter of 2017.

Between December 2009 and August 2011, the Bank entered into four agreements with the Federal Deposit Insurance
Corporation (“FDIC”) to acquire certain assets and assume certain liabilities of four failed banks: Valley Capital Bank,
Home National Bank, Legacy Bank, and The First National Bank of Olathe. In conjunction with each of these, the
Bank entered into loss share agreements, under which the FDIC agreed to reimburse the Bank for a percentage of
losses on certain loans and other real estate acquired for the term of the agreement. In December 2015, the Bank
successfully entered into an agreement with the FDIC for early termination of all existing loss share agreements. Since
the termination, the Bank has fully recognized recoveries, losses, and expenses related to the assets formerly covered
by the agreements, and the FDIC no longer shares in those amounts.  

Subordinated Notes
On November 1, 2016, the Company issued $50 million of 4.75% fixed-to-floating rate subordinated notes with a
maturity date of November 1, 2026. The subordinated notes initially bear interest at an annual rate of 4.75%, with
interest payable semiannually. Beginning November 1, 2021, the interest rate resets quarterly to the three-month London
Interbank Offered Rate (“LIBOR”) plus a spread of 338.7 basis points, payable quarterly. The Company used a portion
of the proceeds from the issuance to pay the cash consideration at the closing of the acquisition of JCB. The remainder
was for general corporate purposes. 

Market Areas and Approach to Geographic Expansion
We operate in the St. Louis, Kansas City, and Phoenix metropolitan areas. The Company, as part of its expansion effort,
plans to continue its strategy of operating branches with larger average deposits, and employing experienced staff who
are compensated on the basis of performance and customer service.

St. Louis - As of December 31, 2017, we operated 19 banking facilities, and five limited service facilities in the St.
Louis metropolitan area. The St. Louis market enjoys a stable, diverse economic base, and is ranked the 18th largest

3

 
metropolitan statistical area in the United States. It is an attractive market with nearly 132,000 privately held businesses
and more than 68,000 households with investable assets of $1.0 million or more. 

Kansas City - We conducted operations in seven banking facilities in the Kansas City market as of December 31, 2017.
Kansas City is also an attractive private company market with over 104,000 privately held businesses and more than
49,000 households with investable assets of $1.0 million or more. It is the 29th largest metropolitan area in the U.S.

Phoenix - We operated two banking facilities in the Phoenix metropolitan area as of December 31, 2017. Phoenix is
the nation's 12th largest metropolitan area, and has more than 232,000 privately held businesses and more than 96,000
households  with  investable  assets  over  $1.0  million. We  believe  Phoenix  is  a  dynamic  growth  market  and  offers
attractive prospects for our business.

Competition
The Company and its subsidiaries operate in highly competitive markets. Our geographic markets are served by a
number of large financial and bank holding companies with substantial capital resources and lending capacity. Many
of the larger banks have established specialized units, which target private businesses and high net worth individuals.
The St. Louis, Kansas City, and Phoenix markets have numerous small community banks. In addition to other financial
holding companies and commercial banks, we compete with credit unions, thrifts, investment managers, brokerage
firms, and other providers of financial services and products.

Supervision and Regulation 
The following is a summary description of the relevant laws, rules, and regulations governing banks and financial
holding companies. The description of, and references to, the statutes and regulations below are brief summaries and
do not purport to be complete. The descriptions are qualified in their entirety by reference to the related statutes and
regulations.

The regulatory and supervisory structure establishes a comprehensive framework of activities in which an institution
can engage and is intended primarily for the protection of depositors, the deposit insurance funds and the banking
system as a whole, rather than for the protection of shareholders or creditors. The regulatory structure also gives the
regulatory  authorities  extensive  discretion  in  connection  with  their  supervisory  and  enforcement  activities  and
examination  policies,  including  policies  concerning  the  establishment  of  deposit  insurance  assessment  fees,
classification of assets and establishment of adequate loan loss reserves for regulatory purposes.

Various legislation is from time to time introduced in Congress and Missouri's legislature. Such legislation may change
applicable statutes and the operating environment in substantial and unpredictable ways. We cannot determine the
ultimate effect that future legislation or implementing regulations would have upon our financial condition or upon
our results of operations or the results of operations of any of our subsidiaries.

On July 21, 2010, the President signed into law the Dodd-Frank Wall Street Reform and Consumer Protection Act of
2010 ("Dodd-Frank Act"), which contains a comprehensive set of provisions designed to govern the practices and
oversight of financial institutions and other participants in the financial markets. The Dodd-Frank Act made extensive
changes in the regulation of financial institutions and their holding companies.

Uncertainty remains as to the ultimate impact of the Dodd-Frank Act, which could have a material adverse impact on
the financial services industry as a whole and the Bank's business, results of operations, and financial condition. Many
aspects of the Dodd-Frank Act have been implemented while other aspects remain subject to further rulemaking. These
regulations will take effect over several years, making it difficult to anticipate the overall financial impact on the
Company, its customers or the financial industry more generally. However, the Dodd-Frank Act has increased the
regulatory burden, compliance costs and interest expense for the Company.

Financial Holding Company
The Company is a financial holding company registered under the Bank Holding Company Act of 1956, as amended
(“BHCA”). As a financial holding company, the Company is subject to regulation and examination by the Federal
Reserve, and is required to file periodic reports of its operations and such additional information as the Federal Reserve

4

may  require.  In  order  to  remain  a  financial  holding  company,  the  Company  must  continue  to  be  considered  well
managed and well capitalized by the Federal Reserve, and the Bank must continue to be considered well managed and
well capitalized by the FDIC, and have at least a “satisfactory” rating under the Community Reinvestment Act. See
“Liquidity and Capital Resources” in the Management Discussion and Analysis for more information on our capital
adequacy, and “Bank Subsidiary - Community Reinvestment Act” below for more information on the Community
Reinvestment Act. 

Acquisitions: With certain limited exceptions, the BHCA requires every financial holding company or bank holding
company to obtain the prior approval of the Federal Reserve before (i) acquiring substantially all the assets of any
bank, (ii) acquiring direct or indirect ownership or control of any voting shares of any bank if, after such acquisition,
it would own or control more than 5% of the voting shares of such bank (unless it already owns or controls the majority
of such shares), or (iii) merging or consolidating with another bank holding company. Additionally, the BHCA provides
that the Federal Reserve may not approve any of these transactions if it would result in or tend to create a monopoly,
substantially lessen competition, or otherwise function as a restraint of trade, unless the anti-competitive effects of the
proposed  transaction  are  clearly  outweighed  by  the  public  interest  in  meeting  the  convenience  and  needs  of  the
community to be served. The Federal Reserve is also required to consider the financial and managerial resources and
future prospects of the bank holding companies and banks concerned and the convenience and needs of the community
to be served. The Federal Reserve’s consideration of financial resources generally focuses on capital adequacy, which
is described below.

Change in Bank Control: Subject to various exceptions, the BHCA and the Change in Bank Control Act, together with
related regulations, require Federal Reserve approval prior to any person or company acquiring “control” of a bank or
financial holding company. Control is conclusively presumed to exist if an individual or company acquires 25% or
more of any class of voting securities of the Company. Control is rebuttably presumed to exist if a person or company
acquires 10% or more, but less than 25%, of any class of voting securities of the Company. The regulations provide a
procedure for challenging rebuttable presumptions of control.

Permitted Activities: The BHCA has generally prohibited a bank holding company from engaging in activities other
than banking or managing or controlling banks or other permissible subsidiaries and from acquiring or retaining direct
or indirect control of any company engaged in any activities other than those determined by the Federal Reserve to be
closely related to banking or managing or controlling banks as to be a proper incident thereto. Provisions of the Gramm-
Leach-Bliley Act have expanded the permissible activities of a bank holding company that qualifies as a financial
holding company. Under the regulations implementing the Gramm-Leach-Bliley Act, a financial holding company
may engage in additional activities that are financial in nature or incidental or complementary to financial activities.
Those activities include, among other activities, certain insurance, advisory and securities activities.

Support of Bank Subsidiaries: Under Federal Reserve policy, the Company is expected to act as a source of financial
strength for the Bank and to commit resources to support the Bank. In addition, pursuant to the Dodd-Frank Act, this
longstanding policy has been given the force of law, and additional regulations promulgated by the Federal Reserve
to further implement the intent of the statute are possible. As in the past, such financial support from the Company
may be required at times when, without this legal requirement, the Company may not be inclined to provide it.

Capital Adequacy: The Company is also subject to capital requirements applied on a consolidated basis, which are
substantially similar to those required of the Bank (summarized below).

Dividend  Restrictions:  Under  Federal  Reserve  policies,  financial  holding  companies  may  pay  cash  dividends  on
common stock only out of income available over the past year if prospective earnings retention is consistent with the
organization's expected future needs and financial condition and if the organization is not in danger of not meeting its
minimum  regulatory  capital  requirements.  Federal  Reserve  policy  also  provides  that  financial  holding  companies
should not maintain a level of cash dividends that undermines the financial holding company's ability to serve as a
source of strength to its banking subsidiaries. 

5

  
Bank Subsidiary 
At December 31, 2017, Enterprise Bank & Trust was our only bank subsidiary. The Bank is a Missouri trust company
with banking powers and is subject to supervision and regulation by the Missouri Division of Finance. In addition, as
a Federal Reserve non-member bank, it is subject to supervision and regulation by the FDIC. The Bank is a member
of the FHLB of Des Moines.

The Bank is subject to extensive federal and state regulatory oversight. The various regulatory authorities regulate or
monitor all areas of the banking operations, including security devices and procedures, adequacy of capitalization and
loss reserves, loans, investments, borrowings, deposits, mergers, issuance of securities, payment of dividends, interest
rates  payable  on  deposits,  interest  rates  or  fees  chargeable  on  loans,  establishment  of  branches,  corporate
reorganizations, maintenance of books and records, and adequacy of staff training to carry on safe lending and deposit
gathering practices. The Bank must maintain certain capital ratios and is subject to limitations on aggregate investments
in  real  estate,  bank  premises,  low  income  housing  projects,  and  furniture  and  fixtures.  In  connection  with  their
supervision and regulation responsibilities, the Bank is subject to periodic examination by the FDIC and Missouri
Division of Finance.

Capital Adequacy:  The Bank is required to comply with the FDIC’s capital adequacy standards for insured banks.
The  FDIC  has  issued  risk-based  capital  and  leverage  capital  guidelines  for  measuring  capital  adequacy,  and  all
applicable capital standards must be satisfied for the Bank to be considered in compliance with regulatory capital
requirements.

On  July  2,  2013,  the  Federal  Reserve  approved  a  final  rule  to  establish  a  new  comprehensive  regulatory  capital
framework for all U.S. banking organizations. This regulatory capital framework, commonly referred to as Basel III,
implements several changes to the U.S. regulatory capital framework required by the Dodd-Frank Act. The U.S. capital
framework  imposed  higher  minimum  capital  requirements,  additional  capital  buffers  above  those  minimum
requirements, a more restrictive definition of capital and higher risk weights for various enumerated classifications of
assets, the combined impact of which effectively results in substantially more demanding capital standards for U.S.
banking organizations.

The Basel III final rule, effective January 1, 2015, established a new common equity tier 1 capital ("CET1") requirement,
an increase in the tier 1 capital requirement from 4.0% to 6.0%, and maintains the current 8.0% total capital requirement.
In addition to these minimum risk-based capital ratios, the Basel III final rule requires that all banking organizations
maintain a "capital conservation buffer" consisting of CET1 capital in an amount equal to 2.5% of risk-weighted assets
in  order  to  avoid  restrictions  on  their  ability  to  make  capital  distributions  and  to  pay  certain  discretionary  bonus
payments  to  executive  officers.  In  order  to  avoid  those  restrictions,  the  capital  conservation  buffer,  when  fully
implemented, will effectively increase the minimum CET1 capital, tier 1 capital, and total capital ratios for U.S. banking
organizations to 7.0%, 8.5%, and 10.5%, respectively. Banking organizations with capital levels that fall within the
buffer will be required to limit dividends, share repurchases or redemptions (unless replaced within the same calendar
quarter by capital instruments of equal or higher quality), and discretionary bonus payments. The capital conservation
buffer is being phased in over a five year period that began January 1, 2016.

As required by the Dodd-Frank Act, the Basel III final rule required capital instruments such as trust preferred securities
and cumulative preferred shares to be phased-out of tier 1 capital by January 1, 2016, for banking organizations that
had $15 billion or more in total consolidated assets as of December 31, 2009, and grandfathered as tier 1 capital such
instruments issued by smaller entities prior to May 19, 2010 (provided they do not exceed 25% of tier 1 capital). The
Company's trust preferred securities are grandfathered under this provision.

The Basel III final rule requires that goodwill and other intangible assets (other than mortgage servicing assets), net
of  associated  deferred  tax  liabilities  ("DTLs"),  be  deducted  from  CET1  capital. Additionally,  deferred  tax  assets
("DTAs")  that  arise  from  net  operating  loss  and  tax  credit  carryforwards,  net  of  associated  DTLs  and  valuation
allowances, are fully deducted from CET1 capital. However, DTAs arising from temporary differences that could not
be realized through net operating loss carrybacks, along with mortgage servicing assets and "significant" (defined as
greater than 10% of the issued and outstanding common stock of the unconsolidated financial institution) investments

6

in the common stock of unconsolidated "financial institutions" are partially includible in CET1 capital, subject to
deductions defined in the final rule.

Prompt Corrective Action: The Bank’s capital categories are determined for the purpose of applying the “prompt
corrective action” rules described below and may be taken into consideration by banking regulators in evaluating
proposals  for  expansion  or  new  activities. They  are  not  necessarily  an  accurate  representation  of  a  bank's  overall
financial condition or prospects for other purposes. A failure to meet the capital guidelines could subject the Bank to
a variety of enforcement actions under those rules, including the issuance of a capital directive, the termination of
deposit insurance by the FDIC, a prohibition on the taking of brokered deposits, and other restrictions on its business.
As described below, the FDIC also can impose other substantial restrictions on banks that fail to meet applicable capital
requirements.

Federal law establishes a system of prompt corrective action to resolve the problems of undercapitalized banks. Under
this  system,  the  FDIC  has  established  five  capital  categories  (“well  capitalized,”  “adequately  capitalized,”
“undercapitalized,” “significantly undercapitalized,” and “critically undercapitalized”) and is required to take various
mandatory supervisory actions, and is authorized to take other discretionary actions with respect to banks in the three
undercapitalized categories. The severity of any such actions taken will depend upon the capital category in which a
bank is placed. Generally, subject to a narrow exception, current federal law requires the FDIC to appoint a receiver
or conservator for a bank that is critically undercapitalized.

Under the FDIC’s prompt corrective action rules, a bank that (1) has a total capital to risk-weighted assets ratio (the
“Total Capital Ratio”) of 10.0% or greater, a tier 1 capital to risk-weighted assets ratio (the “Tier 1 Capital Ratio”) of
8.0% or greater, a CET1 capital to risk-weighted assets ratio (the "CET1 Capital Ratio") of 6.5% or greater, and a tier
1 capital to average assets (the “Leverage Ratio”) of 5.0% or greater, and (2) is not subject to any written agreement,
order, capital directive, or prompt corrective action directive issued by the FDIC, is considered to be “well capitalized.”
A bank with a Total Capital Ratio of 8.0% or greater, a Tier 1 Capital Ratio of 6.0% or greater, a CET1 Capital Ratio
of 4.5% or greater, and a Leverage Ratio of 4.0% or greater, is considered to be “adequately capitalized.” A bank that
has a Total Capital Ratio of less than 8.0%, a Tier 1 Capital Ratio of less than 6.0%, a CET1 Capital Ratio of less than
4.5%, or a Leverage Ratio of less than 4.0%, is considered to be “undercapitalized.” A bank that has a Total Capital
Ratio of less than 6.0%, a Tier 1 Capital Ratio of less than 3.0%, a CET1 Capital Ratio of less than 3.0%, or a Leverage
Ratio of less than 4.0%, is considered to be “significantly undercapitalized,” and a bank that has a tangible equity
capital to total assets ratio equal to or less than 2.0% is deemed to be “critically undercapitalized.” A bank may be
considered  to  be  in  a  capitalization  category  lower  than  indicated  by  its  actual  capital  position  if  it  receives  an
unsatisfactory examination rating or is subject to a regulatory action that requires heightened levels of capital. 

A bank that becomes “undercapitalized,” “significantly undercapitalized,” or “critically undercapitalized” is required
to submit an acceptable capital restoration plan to the FDIC. An “undercapitalized” bank also is generally prohibited
from increasing its average total assets, making acquisitions, establishing new branches, or engaging in any new line
of business, except in accordance with an accepted capital restoration plan or with the approval of the FDIC. Also, the
FDIC may treat an “undercapitalized” bank as being “significantly undercapitalized” if it determines that those actions
are necessary to carry out the purpose of the law.

All of the Bank’s capital ratios were at levels that qualify it to be “well capitalized” for regulatory purposes as of
December 31, 2017.

Consumer  Financial  Protection  Bureau:  The  Dodd-Frank  Act  centralized  responsibility  for  consumer  financial
protection including implementing, examining and enforcing compliance with federal consumer financial laws with
Consumer Financial Protection Bureau (the "CFPB"). Depository institutions with less than $10 billion in assets, such
as our Bank, will be subject to rules promulgated by the CFPB, but will continue to be examined and supervised by
federal banking regulators for consumer compliance purposes.

The Bank is also subject to other laws and regulations intended to protect consumers in transactions with depository
institutions, as well as other laws or regulations affecting customers of financial institutions generally. While the list
set forth herein is not exhaustive, these laws and regulations include the Truth in Lending Act, the Truth in Savings

7

Act, the Electronic Funds Transfer Act, the Expedited Funds Availability Act, the Equal Credit Opportunity Act, the
Fair Housing Act, the Real Estate Settlement and Procedures Act, the Fair Credit Reporting Act and the Federal Trade
Commission Act, among others. These laws and regulations mandate certain disclosure requirements and regulate the
manner in which financial institutions must deal with customers when taking deposits or making loans to such customers.
The Bank must comply with the applicable provisions of these consumer protection laws and regulations as part of its
ongoing customer relations.

UDAP and UDAAP:  Banking regulatory agencies have increasingly used a general consumer protection statute to
address "unethical" or otherwise "bad" business practices that may not necessarily fall directly under the purview of
a specific banking or consumer finance law. The law of choice for enforcement against such business practices has
been Section 5 of the Federal Trade Commission Act-the primary federal law that prohibits unfair or deceptive acts or
practices and unfair methods of competition in or affecting commerce ("UDAP" or "FTC Act"). "Unjustified consumer
injury" is the principal focus of the FTC Act. Moreover, the UDAP provisions have been expanded under the Dodd-
Frank Act to apply to "unfair, deceptive or abusive acts or practices" ("UDAAP"), which has been delegated to the
CFPB for supervision. The CFPB has brought a variety of enforcement actions for violations of UDAAP provisions
and CFPB guidance continues to evolve.

Mortgage Reform:  The CFPB has adopted final rules implementing minimum standards for the origination of residential
mortgages, including standards regarding a customer's ability to repay, restricting variable rate lending by requiring
the ability to repay variable-rate loans be determined by using the maximum rate that will apply during the first five
years of a variable-rate loan term, and making more loans subject to provisions for higher cost loans, new disclosures,
and certain other revisions. In addition, the Dodd-Frank Act allows borrowers to raise certain defenses to foreclosure
if they receive any loan other than a "qualified mortgage" as defined by the CFPB.

Dividends by the Bank Subsidiary:  Under Missouri law, the Bank may pay dividends to the Company only from a
portion of its undivided profits and may not pay dividends if its capital is impaired. As an insured depository institution,
federal law prohibits the Bank from making any capital distributions, including the payment of a cash dividend if it is
“undercapitalized” or after making the distribution would become undercapitalized. If the FDIC believes that the Bank
is engaged in, or about to engage in, an unsafe or unsound practice, the FDIC may require, after notice and hearing,
that the bank cease and desist from that practice. The FDIC has indicated that paying dividends that deplete a depository
institution’s capital base to an inadequate level would be an unsafe and unsound banking practice. The FDIC has issued
policy statements that provide that insured banks generally should pay dividends only from their current operating
earnings.  The  Bank’s  payment  of  dividends  also  could  be  affected  or  limited  by  other  factors,  such  as  events  or
circumstances which lead the FDIC to require that it maintain capital in excess of regulatory guidelines.

Transactions with Affiliates and Insiders:  The Bank is subject to the provisions of Regulation W promulgated by the
Federal Reserve, which encompasses Sections 23A and 23B of the Federal Reserve Act. Regulation W places limits
and conditions on the amount of loans or extensions of credit to, investments in, or certain other transactions with,
affiliates and on the amount of advances to third parties collateralized by the securities or obligations of affiliates.
Regulation W also prohibits, among other things, an institution from engaging in certain transactions with certain
affiliates unless the transactions are on terms substantially the same, or at least as favorable to such institution or its
subsidiaries, as those prevailing at the time for comparable transactions with nonaffiliated companies. Federal law also
places restrictions on the Bank’s ability to extend credit to its executive officers, directors, principal shareholders and
their related interests. These extensions of credit must be made on substantially the same terms, including interest rates
and collateral, as those prevailing at the time for comparable transactions with unrelated third parties; and must not
involve more than the normal risk of repayment or present other unfavorable features.

Community  Reinvestment  Act:  The  Community  Reinvestment  Act  (“CRA”)  requires  that,  in  connection  with
examinations  of  financial  institutions  within  its  jurisdiction,  the  FDIC  shall  evaluate  the  record  of  the  financial
institutions in meeting the credit needs of their local communities, including low and moderate income neighborhoods,
consistent with the safe and sound operation of those institutions. These factors are also considered in evaluating
mergers, acquisitions, and applications to open a branch or facility. The Bank has a satisfactory rating under CRA.

USA PATRIOT Act: The Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept
and Obstruct Terrorism Act of 2001 (the "USA PATRIOT Act") requires each financial institution to: (i) establish an
anti-money laundering program; (ii) establish due diligence policies, procedures and controls with respect to its private
banking accounts and correspondent banking accounts involving foreign individuals and certain foreign banks; and
(iii) implement certain due diligence policies, procedures and controls with regard to correspondent accounts in the
United States for, or on behalf of, a foreign bank that does not have a physical presence in any country. In addition,
the  USA  PATRIOT  Act  contains  a  provision  encouraging  cooperation  among  financial  institutions,  regulatory
authorities  and  law  enforcement  authorities  with  respect  to  individuals,  entities  and  organizations  engaged  in,  or
reasonably suspected of engaging in, terrorist acts or money laundering activities.

Commercial Real Estate Lending: The Bank’s lending operations may be subject to enhanced scrutiny by federal
banking  regulators  based  on  its  concentration  of  commercial  real  estate  loans.  On  December  6,  2006,  the  federal
banking regulators issued final guidance to remind financial institutions of the risk posed by commercial real estate
(“CRE”) lending concentrations.  CRE loans generally include land development, construction loans, and loans secured
by multifamily property, and non-farm, nonresidential real property where the primary source of repayment is derived
from rental income associated with the property. The guidance prescribes the following guidelines for its examiners
to help identify institutions that are potentially exposed to significant CRE risk, including concentrations in certain
types of CRE that may warrant greater supervisory scrutiny: total reported loans for construction, land development,
and other land represent 100% or more of the institutions total capital; or total commercial real estate loans represent
300% or more of the institution’s total capital, and the outstanding balance of the institution’s commercial real estate
loan portfolio has increased by 50% or more.

Volcker Rule: On December 10, 2013, the federal regulators adopted final regulations to implement the proprietary
trading and private fund prohibitions of the Volcker Rule under the Dodd-Frank Act. Under the final regulations, which
became effective July 21, 2015, banking entities are generally prohibited, subject to significant exceptions from: (i)
short-term proprietary trading as principal in securities and other financial instruments, and (ii) sponsoring or acquiring
or retaining an ownership interest in private equity and hedge funds.

Governmental Policies
The operations of the Company and its subsidiaries are affected not only by general economic conditions, but also by
the policies of various regulatory authorities. In particular, the Federal Reserve Board (“FRB”) regulates monetary
policy and interest rates in order to influence general economic conditions. These policies have a significant influence
on overall growth and distribution of loans, investments and deposits and affect interest rates charged on loans or paid
for deposits. FRB monetary policies have had a significant effect on the operating results of all financial institutions
in the past and may continue to do so in the future.

The current U.S. administration has put in place changes to the financial services industry, including changes to policies
and regulations that implement current federal law, including the Dodd-Frank Act, as well as a focus on reviewing and
revising regulations promulgated during the prior administration. At this point we are unable to determine what impact
potential policy changes might have on the Company or its subsidiaries.

Employees
As of December 31, 2017, we had 635 full-time equivalent employees. None of the Company's employees are covered
by a collective bargaining agreement. Management believes that its relationship with its employees is good.

ITEM 1A: RISK FACTORS

An investment in our common shares is subject to risks inherent to our business. Before making an investment decision,
you should carefully consider the risks and uncertainties described below together with all of the other information
included or incorporated by reference in this report. The value of our common shares could decline due to any of these
risks, and you could lose all or part of your investment.

Risks Relating to Our Business 
Our allowance for loan losses may not be adequate to cover actual loan losses.
We maintain an allowance for loan losses, which is a reserve established through a provision for loan losses charged
to  expense,  that  represents  management's  estimate  of  probable  losses  within  the  existing  portfolio  of  loans.  The
allowance, in the judgment of management, is sufficient to reserve for estimated loan losses and risks inherent in the
loan portfolio. We continue to monitor the adequacy of our loan loss allowance and may need to increase it if economic
conditions deteriorate. In addition, bank regulatory agencies periodically review our allowance for loan losses and
may require an increase in the provision for loan losses or the recognition of further loan charge-offs, based on judgments
that can differ somewhat from those of our own management. In addition, if charge-offs in future periods exceed the
allowance for loan losses (i.e., if the loan allowance is inadequate), we may need additional loan loss provisions to
increase the allowance for loan losses. Additional provisions to increase the allowance for loan losses, should they
become necessary, would result in a decrease in net income and a reduction in capital, and may have a material adverse
effect on our financial condition and results of operations.

An economic downturn could adversely affect our financial condition, results of operations or cash flows. 
If the communities in which we operate do not grow, or if prevailing economic conditions locally or nationally are
unfavorable, our business may not succeed. Unpredictable economic conditions may have an adverse effect on the
quality of our loan portfolio and our financial performance. Economic recession or other economic problems in our
market areas could have a material adverse impact on the quality of the loan portfolio and the demand for our products
and services. Adverse changes in the economies in our market areas may have a material adverse effect on our financial
condition, results of operations or cash flows. As a community bank, we bear increased risk of unfavorable local
economic conditions.  Moreover, we cannot give any assurance that we will benefit from any market growth or favorable
economic conditions in our primary market areas even if they do occur.  

Our loan portfolio is concentrated in certain markets which could result in increased credit risk.
A majority of our loans are to businesses and individuals in the St. Louis, Kansas City, and Phoenix metropolitan areas.
The regional economic conditions in areas where we conduct our business have an impact on the demand for our
products and services as well as the ability of our clients to repay loans, the value of the collateral securing loans, and
the stability of our deposit funding sources.  Consequently, a decline in local economic conditions may adversely affect
our earnings. 

There are material risks involved in commercial lending that could adversely affect our business.
Our business plan calls for continued efforts to increase our assets invested in commercial loans. Our credit-rated
commercial loans include commercial and industrial loans to our privately-owned business clients along with loans
to commercial borrowers that are secured by real estate (commercial property, multi-family residential property, 1 - 4
family residential property, and construction and land). Commercial loans generally involve a higher degree of credit
risk than residential mortgage loans due, in part, to their larger average size and less readily-marketable collateral. In
addition, unlike residential mortgage loans, commercial loans generally depend on the cash flow of the borrower’s
business to service the debt. Adverse economic conditions or other factors affecting our target markets may have a
greater adverse effect on us than on other financial institutions that have a more diversified client base. Increases in
non-performing commercial loans could result in operating losses, impaired liquidity and erosion of our capital, and
could have a material adverse effect on our financial condition and results of operations. Credit market tightening
could adversely affect our commercial borrowers through declines in their business activities and adversely impact
their overall liquidity through the diminished availability of other borrowing sources or otherwise. 

10

Our loan portfolio includes loans secured by real estate, which could result in increased credit risk.  
A portion of our portfolio is secured by real estate, and thus we face a high degree of risk from a downturn in our real
estate markets. If real estate values would decline in our markets, our ability to recover on defaulted loans for which
the primary reliance for repayment is on the real estate collateral by foreclosing and selling that real estate would then
be diminished, and we would be more likely to suffer losses on defaulted loans.

Additionally, Kansas and Arizona have foreclosure laws that may hinder our ability to timely or fully recover on
defaulted loans secured by property in their states. Kansas is a judicial foreclosure state, therefore all foreclosures must
be processed through the Kansas state courts. Due to this process, it takes approximately one year for us to foreclose
on real estate collateral located in the State of Kansas. Our ability to recover on defaulted loans secured by Kansas
property may be delayed and our recovery efforts are lengthened due to this process. Arizona has an anti-deficiency
statute with regards to certain types of residential mortgage loans. Our ability to recover on defaulted loans secured
by residential mortgages may be limited to the fair value of the real estate securing the loan at the time of foreclosure.

Our commercial and industrial loans, enterprise value lending / senior debt financing transactions are underwritten
based primarily on cash flow, profitability and enterprise value of the client and are not fully covered by the value of
tangible assets or collateral of the client. Consequently, if any of these transactions becomes non-performing, we could
suffer a loss of some or all of our value in the assets.
Cash flow lending involves lending money to a client based primarily on the expected cash flow, profitability and
enterprise value of a client, with the value of any tangible assets as secondary protection. In some cases, these loans
may have more leverage than traditional bank debt. In the case of our senior cash flow loans, we generally take a lien
on substantially all of a client's assets, but the value of those assets is typically substantially less than the amount of
money we advance to the client under a cash flow transaction. In addition, some of our cash flow loans may be viewed
as stretch loans, meaning they may be at leverage multiples that exceed traditional accepted bank lending standards
for senior cash flow loans. Thus, if a cash flow transaction becomes non-performing, our primary recourse to recover
some or all of the principal of our loan or other debt product would be to force the sale of all or part of the company
as a going concern. Additionally, we may obtain equity ownership in a borrower as a means to recover some or all of
the principal of our loan. The risks inherent in cash flow lending include, among other things:

•

•
•
•

•

reduced use of or demand for the client's products or services and, thus, reduced cash flow of the client to
service the loan and other debt product as well as reduced value of the client as a going concern; 
inability of the client to manage working capital, which could result in lower cash flow; 
inaccurate or fraudulent reporting of our client's positions or financial statements; 
economic downturns, political events, regulatory changes, litigation or acts of terrorism that affect the client's
business, financial condition and prospects; and 
our client's poor management of their business. 

Additionally, many of our clients use the proceeds of our cash flow transactions to make acquisitions. Poorly executed
or poorly conceived acquisitions can burden management, systems and the operations of the existing business, causing
a decline in both the client's cash flow and the value of its business as a going concern. In addition, many acquisitions
involve new management teams taking over day-to-day operations of a business. These new management teams may
fail to execute at the same level as the former management team, which could reduce the cash flow of the client available
to service the loan or other debt product, as well as reduce the value of the client as a going concern.

Widespread financial difficulties or downgrades in the financial strength or credit ratings of life insurance providers
could lessen the value of the collateral securing our life insurance premium finance loans and impair our financial
condition and liquidity.
One of the specialized products we offer is financing high-end whole life insurance premiums utilized in high net
worth estate planning. These loans are primarily secured by the insurance policies financed by the loans, i.e., the
obligations of the life insurance providers under those policies. Nationally Recognized Statistical Rating Organizations
(“NRSROs”) such as Standard & Poor’s, Moody’s and A.M. Best evaluate the life insurance providers that are the
payors on the life insurance policies that we finance. The value of our collateral could be materially impaired in the
event there are widespread financial difficulties among life insurance providers or the NRSROs downgrade the financial
strength ratings or credit ratings of the life insurance providers, indicating the NRSROs’ opinion that the life insurance

11

provider’s ability to meet policyholder obligations is impaired, or the ability of the life insurance provider to meet the
terms of its debt obligations is impaired. The value of our collateral is also subject to the risk that a life insurance
provider could become insolvent. In particular, if one or more large nationwide life insurance providers were to fail,
the value of our portfolio could be significantly negatively impacted. A significant downgrade in the value of the
collateral supporting our premium finance business could impair our ability to create liquidity for this business, which,
in turn could negatively impact our ability to expand.     

Our loan portfolio includes agricultural loans, and the ability of the borrower to repay may be affected by many factors
outside of the borrower's control. 
We engage in lending to agricultural businesses, including farms, for both real estate loans and operational loans. Any
extended period of low commodity prices, drought conditions, significantly reduced yields on crops and/or reduced
levels of government assistance to the agricultural industry could result in an increase in the level of problem agriculture
loans and potentially result in additional provisions to increase our allowance for loan losses, and may have a material
adverse effect on our financial condition and results of operations.

We engage in aircraft financing transactions, in which high-value collateral is susceptible to potential catastrophic
loss.  Consequently, if any of these transactions becomes non-performing, we could suffer a loss of some or all of our
value in the assets.
In  January  2016,  we  acquired  an  aircraft  financing  platform  and  the  associated  portfolio  of  aircraft  loans.  These
transactions are secured by the aircraft financed by the loans. Aircraft as collateral presents unique risks: it is high-
value, but susceptible to rapid movement across different locations and potential catastrophic loss. Although the loan
documentation for these transactions includes insurance covenants and other provisions to protect the lender against
risk of loss, there can be no assurance that, in the event of a catastrophic loss, the insurance proceeds would be sufficient
to ensure our full recovery of the aircraft loan. Moreover, a relatively small number of non-performing aircraft loans
could have a significant negative impact on the value of our portfolio. If we must make additional provisions to increase
our allowance for loan losses, we could experience a decrease in net income and possibly a reduction in capital, which
could have a material adverse effect on our financial condition and results of operations.

We may be obligated to indemnify certain counterparties in financing transactions we enter into pursuant to the New
Markets Tax Credit Program.   
We participate in and are an "Allocatee" of the New Markets Tax Credit Program of the U.S. Department of the Treasury
Community Development Financial Institutions Fund. Through this program, we provide our allocation to certain
projects, which in turn for an equity investment from an Investor in the project generate federal tax credits to those
investors. This  equity,  coupled  with  any  debt  or  equity  from  the  project  sponsor  is  in  turn  invested  in  a  certified
community development entity for a period of at least seven years. Community development entities must use this
capital to make loans to, or other investments in, qualified businesses in low-income communities in accordance with
New Markets Tax Credit Program criteria. Investors receive an overall tax credit equal to 39% of their total equity
investment, credited at a rate of five percent in each of the first three years and six percent in each of the final four
years. However, after the exhaustion of all cure periods and remedies, the entire credit is subject to recapture if the
certified  community  development  entity  fails  to  maintain  its  certified  status,  or  if  substantially  all  of  the  equity
investment proceeds associated with the tax credits we allocate are no longer continuously invested in a qualified
business that meets the New Markets Tax Credit Program criteria, or if the equity investment is redeemed prior to the
end of the minimum seven-year term. As part of these financing transactions, we as the parent to Enterprise Financial
CDE, LLC ("CDE"), provide customary indemnities to the tax credit investors, which require us to indemnify and
hold harmless the investors in the event a credit recapture event occurs, unless the recapture is a result of action or
inaction of the investor. No assurance can be given that these counterparties will not call upon us to discharge these
obligations in the circumstances under which they are owed. If this were to occur, the amount we may be required to
pay a bank investor could be substantial and could have a material adverse effect on our results of operations and
financial condition. 

If we fail to comply with requirements of the federal New Markets Tax Credit program, the U.S. Department of the
Treasury Community Development Financial Institutions Fund could seek any remedies available under its Allocation

12

Agreement with us, and we could suffer significant reputational harm and be subject to greater scrutiny from banking
regulators.
Because we have been designated as an “Allocatee” under the New Markets Tax Credit Program, we are required to
provide allocation fund qualifying projects under the New Markets Tax Credit Program, and we are responsible for
monitoring those projects, ensuring their ongoing compliance with the requirements of the New Markets Tax Credit
Program  and  satisfying  the  various  recordkeeping  and  reporting  requirements  under  the  New  Markets Tax  Credit
Program. If we default in our obligations under the New Markets Tax Credit Program, the U.S. Department of the
Treasury may revoke our participation in any other CDFI Fund programs, reallocate the new market tax credits that
were originally allocated to us, and take any other remedial actions that it is empowered to take under the Allocation
Agreement they have entered into with us with respect to the New Markets Tax Credit Program, with the full range of
such remedies being unknown. If we were to default under the New Markets Tax Credit Program, we could suffer
negative publicity in the communities in which we operate, and we could face greater scrutiny from federal and state
bank regulators, especially with regard to our compliance with the Community Reinvestment Act. These developments
could have a material adverse impact on our reputation, business, financial condition, results of operations and liquidity.

We face potential risks from litigation brought against the Company or its subsidiaries.  
We are involved in various lawsuits and legal proceedings. Pending or threatened litigation against the Company or
the Bank, litigation-related costs and any legal liability as a result of an adverse determination with respect to one or
more of these legal proceedings could have a material adverse effect on our business, cash flows, financial position
or results of operations and/or could cause us significant reputational harm, including without limitation as a result of
negative publicity the Company may face even if it prevails in such legal proceedings, which could adversely affect
our business prospects.

Liquidity risk could impair our ability to fund operations and meet debt coverage obligations, and jeopardize our
financial condition. 
Liquidity is essential to our business. We are a holding company and depend on our subsidiaries for liquidity needs,
including debt coverage requirements. An inability to raise funds through deposits, borrowings, the sale of investment
securities and other sources could have a substantial material adverse effect on our liquidity. Our access to funding
sources in amounts that are adequate to finance our activities could be impaired by factors that affect us specifically
or the financial services industry in general. Factors that could detrimentally impact our access to liquidity sources
include but are not limited to a decrease in the level of our business activity due to a market downturn, our failure to
remain well capitalized, or adverse regulatory action against us. Our ability to acquire deposits or to borrow could also
be impaired by factors that are not specific to us, such as a severe disruption of the financial markets or negative views
and expectations about the prospects for the financial services industry as a whole.

Loss of customer deposits could increase our funding costs.
We rely on bank deposits to be a low cost and stable source of funding. We compete with banks and other financial
services companies for deposits. If our competitors raise the rates they pay on deposits, our funding costs may increase,
either because we raise our rates to avoid losing deposits or because we lose deposits and must rely on more expensive
sources of funding. Higher funding costs could reduce our net interest margin and net interest income and could have
a material adverse effect on our business, financial condition and results of operations.

Our utilization of brokered deposits could adversely affect our liquidity and results of operations.
Since our inception, we have utilized both brokered and non-brokered deposits as a source of funds to support our
growing loan demand and other liquidity needs. As a bank regulatory supervisory matter, reliance upon brokered
deposits as a significant source of funding is discouraged. Brokered deposits may not be as stable as other types of
deposits, and, in the future, those depositors may not renew their deposits when they mature, or we may have to pay
a higher rate of interest to keep those deposits or may have to replace them with other deposits or with funds from
other sources. Additionally, if the Bank ceases to be categorized as “well capitalized” for bank regulatory purposes, it
would not be able to accept, renew or roll over brokered deposits without a waiver from the FDIC. Our inability to
maintain or replace these brokered deposits as they mature could adversely affect our liquidity and results of operations.
Further, paying higher interests rates to maintain or replace these deposits could adversely affect our net interest margin
and results of operations. 

13

We may need to raise additional capital in the future, and such capital may not be available to us or may only be
available on unfavorable terms.
We may need to raise additional capital in the future in order to support growth or manage adverse developments such
as any additional provisions for loan losses, to maintain our capital ratios, or for other reasons. The condition of the
financial markets may be such that we may not be able to obtain additional capital, or the additional capital may only
be available on terms that are not attractive to us.

No assurance can be given that the subordinated notes will continue to qualify as Tier 2 capital. 
We treat the 4.75% fixed-to-floating rate subordinated notes as “Tier 2 capital” under the Board of Governors of the
Federal Reserve System (the “Federal Reserve Board”) regulatory rules and guidelines. If the subordinated notes are
no longer qualified as Tier 2 capital, it could have an adverse effect on our capital requirements under the Federal
Reserve Board rules and guidelines.

Our  business  is  subject  to  interest  rate  risk  and  variations  in  interest  rates  may  negatively  affect  our  financial
performance.  
A substantial portion of our income is derived from the differential or “spread” between the interest earned on loans,
investment securities, and other interest-earning assets, and the interest paid on deposits, borrowings, and other interest-
bearing liabilities. Because of the differences in the maturities and repricing characteristics of our interest-earning
assets and interest-bearing liabilities, changes in interest rates may not produce equivalent changes in interest income
earned on interest-earning assets and interest paid on interest-bearing liabilities. Significant fluctuations in market
interest rates could materially and adversely affect not only our net interest spread, but also our asset quality and loan
origination volume, deposits, funding availability, and/or net income.

We face potential risk from changes in governmental monetary policies.
The Bank’s earnings are affected by domestic economic conditions and the monetary and fiscal policies of the United
States government and its agencies. The Federal Reserve’s monetary policies have had, and are likely to continue to
have, an important impact on the operating results of commercial banks through its power to implement national
monetary policy in order, among other things, to curb inflation or combat a recession. The monetary policies of the
Federal Reserve affect the levels of bank loans, investments, and deposits through its control over the issuance of
United States government securities, its regulation of the discount rate applicable to member banks, and its influence
over reserve requirements to which member banks are subject. The Bank cannot predict the nature or impact of future
changes in monetary and fiscal policies.

The ability of our borrowers to repay their loans may be adversely affected by an increase in market interest rates
which could result in increased credit losses. These increased credit losses, where the Bank has retained credit exposure,
could decrease our assets, net income and cash available. 
The loans we make to our borrowers typically bear interest at a variable or floating interest rate. When market interest
rates increase, the amount of revenue borrowers need to service their debt also increases. Some borrowers may be
unable to make their debt service payments. As a result, an increase in market interest rates will increase the risk of
loan default. An increase in non-performing loans could result in a net loss of earnings from these loans, an increase
in the provision for loan and covered loan losses, and an increase in loan charge-offs, all of which could have a material
adverse effect on our business, financial condition and results of operations. 

By engaging in derivative transactions, we are exposed to additional credit and market risk in our banking business.
We may use interest rate swaps to help manage our interest rate risk in our banking business from recorded financial
assets and liabilities when they can be demonstrated to effectively hedge a designated asset or liability and the asset
or liability exposes us to interest rate risk or risks inherent in client related derivatives. We may use other derivative
financial instruments to help manage other economic risks, such as liquidity and credit risk, including exposures that
arise from business activities that result in the receipt or payment of future known or uncertain cash amounts, the value
of which are determined by interest rates. We also have derivatives that result from a service we provide to certain
qualifying clients approved through our credit process, and therefore, these derivatives are not used to manage interest
rate risk in our assets or liabilities. Hedging interest rate risk is a complex process, requiring sophisticated models and

14

routine monitoring. As a result of interest rate fluctuations, hedged assets and liabilities will appreciate or depreciate
in market value. The effect of this unrealized appreciation or depreciation will generally be offset by income or loss
on the derivative instruments that are linked to the hedged assets and liabilities. By engaging in derivative transactions,
we are exposed to credit and market risk. If the counterparty fails to perform, credit risk exists to the extent of the fair
value gain in the derivative. Market risk exists to the extent that interest rates change in ways that are significantly
different from what we expected when we entered into the derivative transaction. The existence of credit and market
risk associated with our derivative instruments could adversely affect our net interest income and, therefore, could
have a material adverse effect on our business, financial condition, results of operations and future prospects.

If the Company incurs losses that erode its capital, it may become subject to enhanced regulation or supervisory action.
Under federal and state laws and regulations pertaining to the safety and soundness of insured depository institutions,
the Missouri Division of Finance, the Federal Reserve Board, and the FDIC have the authority to compel or restrict
certain actions if the Company's or the Bank's capital should fall below adequate capital standards as a result of future
operating losses, or if its bank regulators determine that it has insufficient capital. Among other matters, the corrective
actions include but are not limited to requiring affirmative action to correct any conditions resulting from any violation
or practice; directing an increase in capital and the maintenance of specific minimum capital ratios; restricting the
Bank's  operations;  limiting  the  rate  of  interest  the  bank  may  pay  on  brokered  deposits;  restricting  the  amount  of
distributions and dividends and payment of interest on its trust preferred securities; requiring the Bank to enter into
informal or formal enforcement orders, including memoranda of understanding, written agreements and consent or
cease  and  desist  orders  to  take  corrective  action  and  enjoin  unsafe  and  unsound  practices;  removing  officers  and
directors and assessing civil monetary penalties; and taking possession of and closing and liquidating the Bank. These
actions may limit the ability of the Bank or Company to execute its business plan and thus can lead to an adverse
impact on the results of operations or financial position.

Changes in government regulation and supervision may increase our costs, or impact our ability to operate in certain
lines of business. 
Our operations are subject to extensive regulation by federal, state and local governmental authorities and are subject
to various laws and judicial and administrative decisions imposing requirements and restrictions on part or all of our
operations. Banking regulations are primarily intended to protect depositors' funds, federal deposit insurance funds
and  the  banking  system  as  a  whole,  not  stockholders.  Because  our  business  is  highly  regulated,  the  laws,  rules,
regulations and supervisory guidance and policies applicable to us are subject to regular modification and change and
could result in an adverse impact on our results of operations. 

Any future increases in FDIC insurance premiums might adversely impact our earnings.  
Over the past several years, the FDIC has adopted several rules which have resulted in a number of changes to the
FDIC assessments, including modification of the assessment system and a special assessment. It is possible that the
FDIC may impose special assessments in the future or further increase our annual assessment, which could adversely
affect our earnings. 

We may be adversely affected by the soundness of other financial institutions.  
Financial services institutions are interrelated as a result of trading, clearing, counterparty or other relationships.  We
have exposure to different institutions and counterparties, and we execute transactions with various counterparties in
the financial industry, including federal home loan banks, commercial banks, brokers and dealers, investment banks
and other institutional clients. Defaults by financial services institutions, and even rumors or questions about one or
more financial services institutions or the financial services industry in general, have led to market-wide liquidity
problems in prior years and could lead to losses or defaults by us or by other institutions. Any such losses could
materially and adversely affect our results of operations or financial position.

We face significant competition.
The financial services industry, including but not limited to, commercial banking, mortgage banking, consumer lending,
and home equity lending, is highly competitive, and we encounter strong competition for deposits, loans, and other
financial services in all of our market areas in each of our lines of business. Our principal competitors include other
commercial  banks,  savings  banks,  savings  and  loan  associations,  mutual  funds,  money  market  funds,  finance

15

companies, trust companies, insurers, credit unions, and mortgage companies among others. Many of our non-bank
competitors are not subject to the same degree of regulation as us and have advantages over us in providing certain
services.  Many of our competitors are significantly larger than us and have greater access to capital and other resources.
Also, our ability to compete effectively in our business is dependent on our ability to adapt successfully to regulatory
and technological changes within the banking and financial services industry, generally. If we are unable to compete
effectively, we will lose market share and our income from loans and other products may diminish.

Our ability to compete successfully depends on a number of factors, including, among other things:

•

•

•
•
•

the ability to develop, maintain, and build upon long-term client relationships based on top quality service and
high ethical standards;
the scope, relevance, and pricing of products and services, including technological innovations to those products
and services, offered to meet client needs and demands;
the rate at which we introduce new products and services relative to our competitors;
client satisfaction with our level of service; and/or
industry and general economic trends.

Failure to perform in any of these areas could significantly weaken our competitive position, and could adversely affect
our growth and profitability, which, in turn, could have a material adverse effect on our financial condition and results
of operations.

We have engaged in and may continue to engage in further expansion through acquisitions, and these acquisitions
present a number of risks related both to the acquisition transactions and to the integration of the acquired businesses.
The acquisition of other financial services companies or assets present risks to the Company in addition to those
presented by the nature of the business acquired. Our earnings, financial condition, and prospects after a merger or
acquisition depend in part on our ability to successfully integrate the operations of the acquired company. We may be
unable to integrate operations successfully or to achieve expected results or cost savings.

Acquiring other banks or businesses involves various risks commonly associated with acquisitions, including,
among other things:

•
•
•
•
•
•
•
•

•

•

potential exposure to unknown or contingent liabilities of the target company;
exposure to potential asset quality issues of the target company;
difficulty and expense of integrating the operations and personnel of the target company;
potential disruption to our business;
potential diversion of our management's time and attention;
the possible loss of key employees and clients of the target company;
difficulty in estimating the value of the target company;
payment of a premium over book and market values that may dilute our tangible book value and
earnings per share in the short- and long-term;
inability to realize the expected revenue increases, cost savings, increases in geographic or product
presence, and/or other projected benefits; and/or
potential changes in banking or tax laws or regulations that may affect the target company.

We periodically evaluate merger and acquisition opportunities and conduct due diligence activities related to possible
transactions  with  other  financial  institutions  and  financial  services  companies. As  a  result,  merger  or  acquisition
discussions and, in some cases, negotiations may take place, and future mergers or acquisitions involving cash, debt
or  equity  securities  may  occur  at  any  time.  In  addition  to  the  risks  noted  above,  potential  acquisitions  may  incur
additional costs for diligence or break-up fees, even if the transaction is not consummated.

We may be unable to successfully integrate new business lines into our existing operations.
From time to time, we may implement other new lines of business or offer new products or services within existing
lines of business. There can be substantial risks and uncertainties associated with these efforts, particularly in instances
where the markets are not fully developed.  Although we continue to expend substantial managerial, operating and
financial resources as our business grows, we may be unable to successfully continue the integration of new business

16

lines, and price and profitability targets may not prove feasible.  External factors such as compliance with regulations,
competitive alternatives and shifting market preferences, may also impact the successful implementation of a new line
of business or a new product or service. Furthermore, any new line of business and new product or service could have
a significant impact on the effectiveness of our system of internal controls. Failure to successfully manage these risks
in the development and implementation of new lines of business or new products or services could have a material
adverse effect on our business, financial condition and results of operations. 

We may not be able to maintain our historical rate of growth, which could have a material adverse effect on our ability
to successfully implement our business strategy.
Successful growth requires that we follow adequate loan underwriting standards, balance loan and deposit growth
without increasing interest rate risk or compressing our net interest margin, maintain adequate capital at all times,
produce investment performance results competitive with our peers and benchmarks, further diversify our revenue
sources, meet the expectations of our clients and hire and retain qualified employees. If we do not manage our growth
successfully, then our business, results of operations or financial condition may be adversely affected.

We may not be able to attract and retain skilled people. 
Our success depends, in large part, on our ability to attract and retain key people. Competition for the best people in
most activities in which we are engaged can be intense, and we may not be able to hire or retain the people we want
and/or  need.  Although  we  maintain  employment  agreements  with  certain  key  employees,  and  have  incentive
compensation plans aimed, in part, at long-term employee retention, the unexpected loss of services of one or more
of our key personnel could still occur, and such events may have a material adverse impact on our business because
of the loss of the employee's skills, knowledge of our market, and years of industry experience and the difficulty of
promptly finding qualified replacement personnel.  

Additionally, executive leadership transitions and succession planning can be inherently difficult to manage and may
cause disruption to our business.  Executive leadership transitions inherently cause some loss of institutional knowledge,
which can negatively affect strategy and execution, and our results of operations and financial condition could suffer
as a result. The loss of services of one or more members of senior management could have a material adverse effect
on our business.

Loss of key employees may disrupt relationships with certain clients.
Our client relationships are critical to the success of our business, and loss of key employees with significant client
relationships may lead to the loss of business if the clients follow that employee to a competitor. While we believe our
relationships with our key personnel are strong, we cannot guarantee that all of our key personnel will remain with us,
which could result in the loss of some of our clients and could have an adverse impact on our business, financial
condition and results of operations.

We may incur impairments to goodwill.
As of December 31, 2017, we had $117.3 million recorded as goodwill. We evaluate our goodwill for impairment at
least annually.  Significant negative industry or economic trends, including the lack of recovery in the market price of
our common stock, or reduced estimates of future cash flows or disruptions to our business, could result in impairments
to  goodwill.  Our  valuation  methodology  for  assessing  impairment  requires  management  to  make  judgments  and
assumptions based on historical experience and to rely on projections of future operating performance. We operate in
competitive environments and projections of future operating results and cash flows may vary significantly from actual
results. If our analysis results in impairment to goodwill, we would be required to record an impairment charge to
earnings in our financial statements during the period in which such impairment is determined to exist. Any such
change could have a material adverse effect on our results of operations and stock price.

Financial deregulation measures proposed by the Trump administration and members of the U.S. Congress may create
regulatory uncertainty for the financial sector and increase competition.
The Trump administration’s short-term legislative agenda may include certain deregulatory measures for the U.S.
financial services industry including, but not limited to, changes to the Volcker Rule, the U.S. Risk Retention Rules,
Basel III capital requirements, the FSOC’s authority, the role, responsibilities and enforcement strategies of the CFPB,

17

capital issues, and various aspects of the Dodd-Frank Act, and implementing regulations promulgated pursuant to the
Dodd-Frank Act.  Measures focused on deregulation of the U.S. financial services industry may have the effect of
increasing competition for our credit-focused businesses or otherwise reducing investment opportunities.  Increased
competition from banks and other financial institutions in the credit markets could have the effect of reducing credit
spreads, which may adversely affect the revenues of our credit and other businesses whose strategies including the
provision of credit to borrowers.  Determining the full extent of the impact on us of any such potential financial reform
legislation, or whether any such particular proposal will become law, is highly speculative.  However, any such changes
may impose additional costs on us, require the attention of our senior management or result in limitations on the manner
in which business is conducted.

The CFPB may reshape the consumer financial laws through rulemaking and enforcement of unfair, deceptive or
abusive acts or practices, which may directly impact the business operations of depository institutions offering consumer
financial products or services, including the Bank.
The Dodd-Frank Act represents a comprehensive overhaul of the financial services industry within the United States,
establishes the new federal Consumer Financial Protection Bureau (the “CFPB”), and will require the CFPB and other
federal agencies to implement many new rules. 

The CFPB has broad powers to supervise and enforce consumer protection laws. The CFPB has broad rule-making
authority for a wide range of consumer protection laws that apply to all banks, including the authority to prohibit unfair,
deceptive or abusive acts and practices. In addition, the Dodd-Frank Act enhanced the regulation of mortgage banking
and gave to the CFPB oversight of many of the core laws which regulate the mortgage industry and the authority to
implement  mortgage  regulations. Any  new  regulations  adopted  by  the  CFPB  may  significantly  impact  consumer
mortgage lending and servicing.

We are subject to numerous laws designed to protect consumers, including the Community Reinvestment Act and
fair lending laws, and failure to comply with these laws could lead to a wide variety of sanctions.
The Community Reinvestment Act, the Equal Credit Opportunity Act, the Fair Housing Act and other fair lending
laws  and  regulations  impose  nondiscriminatory  lending  requirements  on  financial  institutions.  The  CFPB,  the
Department of Justice and other federal agencies are responsible for enforcing these laws and regulations. A successful
regulatory challenge to an institution's performance under the Community Reinvestment Act or fair lending laws and
regulations could result in a wide variety of sanctions, including damages and civil money penalties, injunctive relief,
restrictions on mergers and acquisitions activity, restrictions on expansion, and restrictions on entering new business
lines. Private parties may also have the ability to challenge an institution's performance under fair lending laws in
private class action litigation. Such actions could have a material adverse effect on our business, financial condition,
results of operations and future prospects.

We are subject to compliance with the Bank Secrecy Act and other anti-money laundering statutes and regulations,
and failure to comply with these laws could lead to a wide variety of sanctions.
The Bank Secrecy Act, the USA PATRIOT Act of 2001, and other laws and regulations require financial institutions,
among other duties, to institute and maintain an effective anti-money laundering program and file suspicious activity
and currency transaction reports when appropriate. In addition to other bank regulatory agencies, the federal Financial
Crimes  Enforcement  Network  of  the  Department  of  the Treasury  is  authorized  to  impose  significant  civil  money
penalties for violations of those requirements and has recently engaged in coordinated enforcement efforts with the
state  and  federal  banking  regulators,  as  well  as  the  U.S.  Department  of  Justice,  CFPB,  Drug  Enforcement
Administration, and Internal Revenue Service. We are also subject to increased scrutiny of compliance with the rules
enforced by the Office of Foreign Assets Control of the Department of the Treasury regarding, among other things,
the prohibition of transacting business with, and the need to freeze assets of, certain persons and organizations identified
as a threat to the national security, foreign policy or economy of the United States. If our policies, procedures and
systems are deemed deficient, we would be subject to liability, including fines and regulatory actions, which may
include restrictions on our ability to pay dividends and the necessity to obtain regulatory approvals to proceed with
certain aspects of our business plan, including any acquisition plans. Failure to maintain and implement adequate
programs to combat money laundering and terrorist financing could also have serious reputational consequences for

18

us. Any of these results could have a material adverse effect on our business, financial condition, results of operations
and future prospects.

Declines in asset values may result in impairment charges and adversely impact the value of our investments and our
financial performance and capital.
We  hold  an  investment  securities  portfolio  that  includes,  but  is  not  limited  to,  government  securities  and  agency
mortgage-backed securities. Factors beyond our control can significantly influence the fair value of securities in our
portfolio and can cause potential adverse changes to the fair value of these securities.  These factors include, but are
not limited to, rating agency actions in respect to the securities, defaults by the issuer or with respect to the underlying
securities, changes in market interest rates and instability in the capital markets.  Any of these factors, among others,
could cause other-than-temporary impairments and realized or unrealized losses in future periods and declines in other
comprehensive income (loss), which could have a material adverse effect on our business, results of operations, financial
condition and future prospects.  The process for determining whether impairment of a security is other-than-temporary
often requires complex, subjective judgments about whether there has been significant deterioration in the financial
condition of the issuer, whether management has the intent or ability to hold a security for a period of time sufficient
to allow for any anticipated recovery in fair value, the future financial performance and liquidity of the issuer and any
collateral underlying the security and other relevant factors. 

Our  investment  securities  portfolio  includes  $12.9  million  in  capital  stock  of  the  FHLB  of  Des  Moines  as  of
December 31, 2017.  This stock ownership is required for us to qualify for membership in the FHLB system, which
enables us to borrow funds under the FHLB advance program.  If the FHLB experiences a capital shortfall, it could
suspend  its  quarterly  cash  dividend,  and  possibly  require  its  members,  including  us,  to  make  additional  capital
investments in the FHLB.  If the FHLB were to cease operations, or if we were required to write-off our investment
in the FHLB, our financial condition, and results of operations may be materially and adversely affected.

The Volcker Rule limits the permissible strategies for managing our investment portfolio.
On December 10, 2013, pursuant to the Dodd-Frank Act, federal banking and securities regulators issued final rules
to implement Section 619 of the Dodd-Frank Act (the "Volcker Rule"). Generally, subject to a transition period and
certain exceptions, the Volcker Rule restricts insured depository institutions and their affiliated companies from: (i)
short-term proprietary trading as principal in securities and other financial instruments, and (ii) sponsoring or acquiring
or retaining an ownership interest in private equity and hedge funds. After the transition period, the Volcker Rule
prohibitions and restrictions will apply to banking entities, including the Company, unless an exception applies. The
Volcker Rule limits or excludes us from holding certain investment securities, which we could otherwise use to diversify
our assets and for asset/liability management.

We primarily invest in mortgage-backed obligations and such obligations have been, and are likely to continue to be,
impacted by market dislocations, declining home values and prepayment risk, which may lead to volatility in cash flow
and market risk and declines in the value of our investment portfolio.
Our investment portfolio largely consists of mortgage-backed obligations primarily secured by pools of mortgages on
single-family residences. The value of mortgage-backed obligations in our investment portfolio may fluctuate for
several reasons, including (i) delinquencies and defaults on the mortgages underlying such obligations, due in part to
high unemployment rates, (ii) falling home prices, (iii) lack of a liquid market for such obligations, (iv) uncertainties
in respect of government-sponsored enterprises such as the Federal National Mortgage Association (“Fannie Mae”)
or the Federal Home Loan Mortgage Corporation (“Freddie Mac”), which guarantee such obligations, and (v) the
expiration of government stimulus initiatives. Although home values had declined over the last several years, prices
appear to have now leveled off. However, if the value of homes were to further materially decline, the fair value of
the mortgage-backed obligations in which we invest may also decline. Any such decline in the fair value of mortgage-
backed obligations, or perceived market uncertainty about their fair value, could adversely affect our financial position
and results of operations. In addition, when we acquire a mortgage-backed security, we anticipate that the underlying
mortgages will prepay at a projected rate, thereby generating an expected yield. Prepayment rates generally increase
as interest rates fall and decrease when rates rise, but changes in prepayment rates are difficult to predict. In light of
historically low interest rates, many of our mortgage-backed securities have a higher interest rate than prevailing market
rates, resulting in a premium purchase price. In accordance with applicable accounting standards, we amortize the

19

premium over the expected life of the mortgage-backed security. If the mortgage loans securing the mortgage-backed
security prepay more rapidly than anticipated, we would have to amortize the premium on an accelerated basis, which
would thereby adversely affect our profitability.

A failure in or breach of our operational or security systems, or those of our third party service providers, including
as a result of cyber attacks, could disrupt our business, result in unintentional disclosure or misuse of confidential or
proprietary information, damage our reputation, increase our costs and adversely impact our earnings.
As a financial institution, our operations rely heavily on the secure processing, storage and transmission of confidential
and  other  information  on  our  computer  systems  and  networks. Any  failure,  interruption  or  breach  in  security  or
operational integrity of these systems could result in failures or disruptions in our internet banking system, treasury
management products, check and document imaging, remote deposit capture systems, general ledger, and other systems.
The security and integrity of our systems could be threatened by a variety of interruptions or information security
breaches, including those caused by computer hacking, cyber attacks, electronic fraudulent activity or attempted theft
of financial assets.  We cannot assure any such failures, interruption or security breaches will not occur, or if they do
occur, that they will be adequately addressed. While we have certain protective policies and procedures in place, the
nature  and  sophistication  of  the  threats  continue  to  evolve. We  may  be  required  to  expend  significant  additional
resources in the future to modify and enhance our protective measures. Additionally, we face the risk of operational
disruption, failure, termination or capacity constraints of any of the third parties that facilitate our business activities,
including exchanges, clearing agents, clearing houses or other financial intermediaries. Such parties could also be the
source of an attack on, or breach of, our operational systems. Any failures, interruptions or security breaches in our
information systems could damage our reputation, result in a loss of client business, result in a violation of privacy or
other laws, or expose us to civil litigation, regulatory fines or losses not covered by insurance.

We rely on third-party vendors to provide key components of our business infrastructure.
We rely heavily on third-party service providers for much of our communications, information, operating and financial
control systems technology, including relationship management, mobile banking, general ledger, investment, deposit,
loan servicing and loan origination systems. While we have selected these third-party vendors carefully and perform
ongoing monitoring, we do not control their actions. Any problems caused by these third parties, including as a result
of inadequate or interrupted service, could adversely affect our ability to deliver products and services to our clients
and otherwise conduct our business. Financial or operational difficulties of a third-party vendor could also hurt our
operations if those difficulties interfere with the vendor’s ability to serve us, and replacing these third-party vendors
could result in significant delay and expense. Accordingly, use of such third parties creates an unavoidable inherent
risk to our business operations as well as reputational risk.

We are subject to environmental risks associated with owning real estate or collateral.
When a borrower defaults on a loan secured by real property, the Company may purchase the property in foreclosure
or accept a deed to the property surrendered by the borrower. We may also take over the management of commercial
properties whose owners have defaulted on loans. We may also own and lease premises where branches and other
facilities are located. While we will have lending, foreclosure and facilities guidelines intended to exclude properties
with  an  unreasonable  risk  of  contamination,  hazardous  substances  could  exist  on  some  of  the  properties  that  the
Company may own, manage or occupy. We face the risk that environmental laws could force us to clean up the properties
at the Company's expense.  The cost of cleaning up or paying damages and penalties associated with environmental
problems could increase our operating expenses. It may cost much more to clean a property than the property is worth.
We could also be liable for pollution generated by a borrower's operations if the Company takes a role in managing
those operations after a default. The Company may also find it difficult or impossible to sell contaminated properties.

Risks Relating to Our Common Stock 
The price of our common stock may be volatile or may decline. 
The trading price of our common stock may fluctuate widely as a result of a number of factors, many of which are
outside our control. In addition, the stock market is subject to fluctuations in the share prices and trading volumes that
affect the market prices of the shares of many companies. These broad market fluctuations could make it more difficult
for you to resell your common stock when you want and at prices you find attractive. 

20

Our stock price can fluctuate significantly in response to a variety of factors including, among other things:

•
•

•
•
•
•
•
•

•
•
•

actual or anticipated quarterly fluctuations in our operating results and financial condition;
changes in revenue or earnings estimates or publication of research reports and recommendations by
financial analysts;
failure to meet analysts' revenue or earnings estimates;
speculation in the press or investment community;
strategic actions by us or our competitors, such as acquisitions or restructurings;
actions by institutional stockholders;
fluctuations in the stock prices and operating results of our competitors;
general market conditions and, in particular, developments related to market conditions for the financial
services industry;
proposed or adopted regulatory changes or developments;
anticipated or pending investigations, proceedings or litigation that involve or affect us; and/or
domestic and international economic factors unrelated to our performance.

The stock market and, in particular, the market for financial institution stocks, has historically experienced significant
volatility. As a result, the market price of our common stock may be volatile. In addition, the trading volume in our
common stock may fluctuate more than usual and cause significant price variations to occur. The trading price of the
shares of our common stock and the value of our other securities will depend on many factors, which may change
from time to time, including, without limitation, our financial condition, performance, creditworthiness and prospects,
future sales of our equity or equity related securities, and other factors identified in this annual report and other reports
by the Company. In some cases, the markets have produced downward pressure on stock prices and credit availability
for certain issuers without regard to those issuers' underlying financial strength or operating results. A significant
decline in our stock price could result in substantial losses for individual stockholders and could lead to costly and
disruptive securities litigation.

The trading volume in our common stock is less than that of other larger financial institutions.
Although our common stock is listed for trading on the NASDAQ Global Select Market, its trading volume may be
less than that of other, larger financial services companies. A public trading market having the desired characteristics
of depth, liquidity and orderliness depends on the presence in the marketplace of willing buyers and sellers of our
common stock at any given time, a factor over which we have no control. During any period of lower trading volume
of our common stock, significant sales of shares of our common stock or the expectation of these sales could cause
our common stock price to fall.

An investment in our common stock is not insured and you could lose the value of your entire investment.
An investment in our common stock is not a savings account, deposit or other obligation of our bank subsidiary, any
non-bank subsidiary or any other bank, and such investment is not insured or guaranteed by the FDIC or any other
governmental agency. As a result, if you acquire our common stock, you may lose some or all of your investment. 

Our ability to pay dividends is limited by various statutes and regulations and depends primarily on the Bank's ability
to distribute funds to us, and is also limited by various statutes and regulations.  
The Company depends on payments from the Bank, including dividends, management fees and payments under tax
sharing agreements, for substantially all of the Company's revenue. Federal and state regulations limit the amount of
dividends and the amount of payments that the Bank may make to the Company under tax sharing agreements. In
certain circumstances, the Missouri Division of Finance, FDIC, or Federal Reserve Board could restrict or prohibit
the Bank from distributing dividends or making other payments to us. In the event that the Bank was restricted from
paying dividends to the Company or making payments under the tax sharing agreement, the Company may not be able
to service its debt, pay its other obligations or pay dividends on its common stock. If we are unable or determine not
to pay dividends on our outstanding equity securities, the market price of such securities could be materially adversely
affected.

There can be no assurance of any future dividends on our common stock.
Holders of our common stock are entitled to receive dividends only when, as and if declared by our board of directors.
Although we have historically paid cash dividends on our common stock, we are not required to do so. 

21

There may be future sales or other dilution of our equity, which may adversely affect the market price of our common
stock.  
We  are  not  restricted  from  issuing  additional  common  stock  or  preferred  stock,  including  any  securities  that  are
convertible into or exchangeable for, or that represent the right to receive, common stock or preferred stock or any
substantially similar securities. For example, we issued 3.3 million new shares of common stock in 2017 at the closing
of the merger with JCB, which resulted in dilution to our shareholders.

In addition, to the extent awards to issue common stock under our employee equity compensation plans are exercised,
or shares are issued, holders of our common stock could incur additional dilution. Further, if we sell additional equity
or convertible debt securities, such sales could result in increased dilution to our stockholders. The market price of our
common stock could decline as a result of sales of a large number of shares of common stock or preferred stock or
similar securities in the market after an offering or the perception that such sales could occur.

Our outstanding debt securities, related to our trust preferred securities, restrict our ability to pay dividends on our
capital stock.  
We have outstanding subordinated debentures issued to statutory trust subsidiaries, which have issued and sold preferred
securities in the Trusts to investors.

If we are unable to make payments on any of our subordinated debentures for more than 20 consecutive quarters, we
would be in default under the governing agreements for such securities and the amounts due under such agreements
would be immediately due and payable. Additionally, if for any interest payment period we do not pay interest in
respect of the subordinated debentures (which will be used to make distributions on the trust preferred securities), or
if for any interest payment period we do not pay interest in respect of the subordinated debentures, or if any other event
of default occurs, then we generally will be prohibited from declaring or paying any dividends or other distributions,
or redeeming, purchasing or acquiring, any of our capital securities, including the common stock, during the next
succeeding  interest  payment  period  applicable  to  any  of  the  subordinated  debentures,  or  next  succeeding  interest
payment period, as the case may be.

Moreover, any other financing agreements that we enter into in the future may limit our ability to pay cash dividends
on our capital stock, including the common stock.  In the event that our existing or future financing agreements restrict
our ability to pay dividends in cash on the common stock, we may be unable to pay dividends in cash on the common
stock unless we can refinance amounts outstanding under those agreements.  In addition, if we are unable or determine
not to pay interest on our subordinated debentures, the market price of our common stock could be materially or
adversely affected.

Anti-takeover provisions could negatively impact our stockholders.
Provisions of Delaware law and of our certificate of incorporation, as amended, and bylaws, as well as various provisions
of federal and Missouri state law applicable to bank and bank holding companies, could make it more difficult for a
third party to acquire control of us or have the effect of discouraging a third party from attempting to acquire control
of us. We are subject to Section 203 of the Delaware General Corporation Law, which would make it more difficult
for  another  party  to  acquire  us  without  the  approval  of  our  board  of  directors.  Additionally,  our  certificate  of
incorporation,  as  amended,  authorizes  our  board  of  directors  to  issue  preferred  stock  which  could  be  issued  as  a
defensive measure in response to a takeover proposal. In the event of a proposed merger, tender offer or other attempt
to gain control of the Company, our board of directors would have the ability to readily issue available shares of
preferred stock as a method of discouraging, delaying or preventing a change in control of the Company. Such issuance
could occur regardless of whether our stockholders favorably view the merger, tender offer or other attempt to gain
control of the Company. These and other provisions could make it more difficult for a third party to acquire us even
if an acquisition might be in the best interests of our stockholders. Although we have no present intention to issue any
shares of our authorized preferred stock, there can be no assurance that the Company will not do so in the future.

Not applicable.

ITEM 2: PROPERTIES

Our executive offices are located at 150 North Meramec, Clayton, Missouri, 63105. As of December 31, 2017, we had
19 banking locations, and five limited service facilities in the St. Louis metropolitan area, seven banking locations in
the Kansas City metropolitan area, and two banking locations in the Phoenix metropolitan area. We own 16 of the
facilities and lease the remainder.  Most of the leases expire between 2018 and 2024 and include one or more renewal
options of up to five years. One lease expires in 2029. All the leases are classified as operating leases. We believe all
of our properties are in good condition. 

ITEM 3: LEGAL PROCEEDINGS

The Company and its subsidiaries are, from time to time, parties to various legal proceedings arising out of their
businesses. Management believes that there are no such proceedings pending or threatened against the Company or
its subsidiaries which, if determined adversely, would have a material adverse effect on the business, consolidated
financial condition, results of operations or cash flows of the Company or any of its subsidiaries.

ITEM 5: MARKET FOR REGISTRANT'S COMMON EQUITY, RELATED STOCKHOLDER MATTERS
AND ISSUER PURCHASES OF EQUITY SECURITIES

Common Stock Market Prices
The Company's common stock trades on the NASDAQ Global Select Market under the symbol “EFSC.” Below are
the dividends declared by quarter along with the closing, high, and low sales prices for the common stock for the
periods indicated, as reported by the NASDAQ Global Select Market. There may have been other transactions at prices
not known to the Company. As of February 21, 2018, the Company had 422 common stock shareholders of record and
a market price of $47.90 per share. The number of holders of record does not represent the actual number of beneficial
owners of our common stock because securities dealers and others frequently hold shares in “street name” for the
benefit of individual owners who have the right to vote shares.

Dividends
The holders of shares of our common stock are entitled to receive dividends when declared by our Board of Directors
out of funds legally available for the purpose of paying dividends. Our ability to pay dividends is substantially dependent
upon the ability of our subsidiaries to pay cash dividends to us. Information on regulatory restrictions on our ability
to pay dividends is set forth in Part I, Item 1 - Business - Supervision and Regulation - Financial Holding Company -
Dividend Restrictions. The amount of dividends, if any, that may be declared by the Company also depends on many
other factors, including future earnings, bank regulatory capital requirements and business conditions as they affect
the Company and its subsidiaries. As a result, no assurance can be given that dividends will be paid in the future with
respect to our common stock.

(a) Includes shares of the Company’s common stock withheld to satisfy tax withholding obligations upon the vesting of awards of restricted
stock. These shares were purchased pursuant to the terms of the applicable plan and not pursuant to a publicly announced repurchase plan or
program.

(b) In May 2015, the Company’s board of directors authorized the repurchase of up to two million shares of the Company’s common stock. The
repurchases may be made in open market or privately negotiated transactions and the repurchase program will remain in effect until fully utilized
or until modified, superseded or terminated. The timing and exact amount of common stock repurchases will depend on a number of factors
including, among others, market and general economic conditions, economic capital and regulatory capital considerations, alternative uses of
capital, the potential impact on our credit ratings, and contractual and regulatory limitations.

Performance Graph
The following Stock Performance Graph and related information should not be deemed “soliciting material” or to be
“filed” with the SEC nor shall such performance be incorporated by reference into any future filings under the Securities
Act of 1933 or Securities Exchange Act of 1934, each as amended, except to the extent that the Company specifically
incorporates it by reference into such filing.

The  following  graph*  compares  the  cumulative  total  shareholder  return  on  the  Company's  common  stock  from
December 31, 2012 through December 31, 2017. The graph compares the Company's common stock with the NASDAQ
Composite,  and the SNL $1B-$5B Bank Index, as well as the SNL $5B-$10B Bank Index as the Company's total
assets exceeded $5 billion in 2017. The graph assumes an investment of $100.00 in the Company's common stock and
each index on December 31, 2012 and reinvestment of all quarterly dividends. The investment is measured as of each
subsequent fiscal year end. There is no assurance that the Company's common stock performance will continue in the
future with the same or similar results as shown in the graph.

termination of all existing FDIC loss share agreements.

Below  are  highlights  of  the  Company's  core  performance  measures,  which  we  believe  are  important  measures  of
financial performance, but are "non-GAAP financial measures."  Generally, a non-GAAP financial measure is a measure
of a company's financial performance, financial position, or cash flows that exclude (or include) amounts that are
included in (or excluded from) the most directly comparable measure calculated and presented in accordance with
generally accepted accounting principles in the U.S. ("GAAP").  The Company's core performance measures include
contractual interest on non-core acquired loans, but exclude incremental accretion on these loans, and exclude the
change in the FDIC loss share receivable, gain or loss on the sale of other real estate from non-core acquired loans,
and expenses directly related to non-core acquired loans and other assets formerly covered under FDIC loss share
agreements.  Core  performance  measures  also  exclude  certain  other  income  and  expense  items,  such  as  executive
separation  costs,  merger  related  expenses,  facilities  charges,  deferred  tax  asset  revaluation  associated  with  U.S.
corporate income tax reform, and the gain or loss on sale of investment securities, which the Company believes are
not indicative of or useful to measure the Company's operating performance on an ongoing basis. A reconciliation of

Measures."

(1) A non-GAAP measure.  A reconciliation has been included in this MD&A section under the caption "Use of Non-GAAP Financial
Measures."

The Company noted the following trends during 2017:

•

The Company reported net income of $48.2 million, or $2.07 per diluted share for 2017, compared to $48.8
million, or $2.41 per diluted share for 2016. Net income year over year increased from earnings of the acquisition
of Jefferson County Bancshares, Inc. ("JCB") and organic growth coupled with net interest margin expansion.
However, reported earnings declined from the prior year due to the deferred tax asset ("DTA") revaluation
charge of $12.1 million, within income tax expense, due to U.S. corporate income tax reform.

• On a core basis1, net income was $59.9 million, or $2.58 per diluted share in 2017, compared to $41.2 million,
or $2.03 per diluted share in 2016. Core earnings per share1 and net income1 for the year 2017 exclude negative
impacts from the DTA revaluation associated with the U.S. corporate income tax reform of $0.52 per share
($12.1  million),  and  merger-related  expenses  of  $0.18  (or  $4.5  million  after  tax). These  calculations  also
exclude income from non-core acquired loans of $0.20 per share ($5.4 million after tax).

• Net interest income for 2017 totaled $177.3 million, an increase of $41.8 million, or 31%, compared to $135.5
million for 2016. Core net interest income1 growth of $46.1 million, or 37%, was due to approximately 11
months of net interest income from the acquisition of JCB, organic growth in portfolio loan balances funded
principally by core deposits1, and a 21 basis point expansion of core net interest margin1
. Additionally, non-
core acquired assets1 contributed $7.7 million to net interest income during 2017, but continued declining
balances in this portfolio led to a $4.3 million decline from 2016 levels. This trend mitigated the impact of the
expansion in core net interest margin1.

• Net interest margin increased four basis points to 3.88% during 2017, compared to 3.84% in 2016, largely due
to core net interest margin1 expansion constricted by a reduction in  incremental accretion on non-core acquired
loans due to declining balances in this portfolio. Core net interest margin1, defined as net interest margin (fully
tax  equivalent),  including  contractual  interest  on  non-core  acquired  loans,  but  excluding  the  incremental
accretion on these loans, increased twenty-one basis points to 3.72% in 2017, from 3.51% in the prior year.
The increase was largely due to the impact of interest rate increases on the Company's asset sensitive balance

30

sheet. Specifically, the yield on portfolio loans increased 41 basis points to 4.63% from 4.22% due to the effect
of increasing interest rates on the existing variable-rate loan portfolio and higher rates on newly originated
loans. The increased cost of total deposits was limited to eight basis points and was 0.44% for 2017. The cost
of total interest-bearing liabilities increased 22 basis points to 0.74%, which included the impact of the issuance
of $50 million of 4.75% subordinated notes in November 2016.

• Noninterest income increased $5.3 million, or 18%, to $34.4 million in 2017 compared to $29.1 million in
2016. This  improvement  was  primarily  due  to  higher  income  from  deposit  service  charges,  card  services
income, and wealth management revenue from the acquisition of JCB, and a growth in the client base. For
2017:

◦ Deposit service charges increased $2.4 million, or 28%
◦
Income from card services increased $2.3 million, or 74%
◦ Wealth management revenue increased $1.4 million, or 20%
◦ Other income increased $1.1 million, or 18%

This income growth was partially offset by lower gains on the sale of other real estate, which declined $1.7
million from 2016.

• Noninterest expenses totaled $115.1 million for 2017, an increase of $28.9 million, or 34%, compared to 2016.
Excluding non-comparable items, such as merger related expenses ($6.5 million), core noninterest expense1
totaled $108.0 million, an increase of $25.7 million, or 31% from the prior year. The year-over-year increase
primarily represents the additional operating and run-rate expenses associated with the JCB acquisition, as
well as continued investments in underlying business growth. The Company's core efficiency ratio1 was 52.93%
for 2017, compared to 54.70% for the prior year. The improvement reflects continuing efforts to leverage the
Company's expense base through revenue growth and completion of the initiatives necessary to realize the
expected cost savings from the JCB acquisition.

• As a result of changes to the U.S. corporate tax rate, a revaluation of the Company's DTA was completed in
the  fourth  quarter,  resulting  in  a  $12.1  million  charge  to  2017  earnings.  The  effect  of  the  charge  on  key
performance measures is demonstrated in the table below:

Diluted Earnings Per Share

Return on Average Assets

Return on Average Common Tangible Equity

Full Year 
2017 Effect
$(0.52)

14.00%

(0.24)%

(2.92)%

The resulting effective tax rate for the year was 44.3%. The revaluation expense is considered a non-core item
and is not included in the Company's core numbers. The Company's core effective tax rate1 was 29.7% for the
year ended December 31, 2017 compared to 34.1% for the prior year. The improvement in the core effective
tax rate1 resulted primarily from the benefit of tax credit investments and other income tax planning initiatives.
These decreases were partially offset by increased pre-tax earnings, which lessen the rate impact of permanent
tax differences.

2017 Significant Transactions
During 2017, we completed the following significant transactions:

• On February 10, 2017, the Company announced the completion of its acquisition of JCB which was merged

with and into the Company, and Eagle Bank and Trust Company of Missouri, JCB's wholly-owned
subsidiary, merged with and into the Bank. As part of the acquisition, 3.3 million shares of the Company’s

31

 
common stock were issued and approximately $29.3 million in cash was paid to JCB shareholders and
holders of JCB stock options. The overall transaction had a value of approximately $171.0 million,
including JCB’s common stock and stock options.

•

The Company repurchased 429,955 of its common shares at a weighted-average share price of $38.69,
pursuant to its publicly announced program.

2016 Significant Transactions
During 2016, we completed the following significant transactions:

• On October 10, 2016, the Company entered into a definitive merger agreement to acquire JCB headquartered in
Jefferson County, Missouri. JCB is the parent holding company of Eagle Bank and Trust Company of Missouri.
The transaction closed on February 10, 2017.

• On November 1, 2016, the Company issued $50 million aggregate principal amount of 4.75% fixed-to-floating
rate subordinated notes with a maturity date of November 1, 2026. The subordinated notes will initially bear an
annual interest rate of 4.75%, with interest payable semiannually.  Beginning November 1, 2021, the interest rate
resets quarterly to the three-month LIBOR plus a spread of 338.7 basis points, payable quarterly. The Company
used a portion of the proceeds from the issuance to pay the cash consideration at the closing of the acquisition of
JCB.  Regulatory guidance allows for this subordinated debt to be treated as tier 2 regulatory capital for the first
five years of its term, subject to certain limitations, and then phased out of tier 2 capital pro rata over the next five
years.  

•

•

The Company repurchased 185,718 of its common shares at a weighted-average share price of $26.32 pursuant
to its publicly announced program during the year ended December 31, 2016. The Company's Board authorized
the repurchase plan in May of 2015, which allows the Company to repurchase up to two million common shares,
representing approximately 10% of the Company’s then currently outstanding shares. Shares may be bought back
in open market or privately negotiated transactions over an indeterminate time period based on market and business
conditions.

The Company's Board approved three consecutive increases in the Company's quarterly cash dividend to $0.11
per common share for the fourth quarter of 2016, up from $0.09 for the first quarter of 2016, expanding cash
dividends paid for the year by 56%.

2015 Significant Transactions
During 2015, we completed the following significant transactions:

•

•

The Company's Board approved three consecutive increases in the Company's quarterly cash dividend to $0.08
per common share for the fourth quarter of 2015, up from $0.0525 for the first quarter of 2015.

The Company received a $65 million allocation of New Markets Tax Credits ("NMTC"), which is the fourth
allocation of NMTC received since 2011, for a total of $183 million.

• On December 7, 2015, the Company successfully completed early termination of all existing loss share agreements
with the FDIC, resulting in a pretax charge of $2.4 million, or $0.07 per diluted share. The Company's income has
been positively impacted by no longer amortizing the FDIC loss share receivable or providing for further increases
to the clawback liability, as well as recovering amounts greater than the carrying value of the formerly covered
assets.  The charge from the termination was entirely earned back in the first quarter of 2016.

Balance sheet highlights  
•

Loans - Loans totaled $4.1 billion at December 31, 2017, including $30.4 million of non-core acquired loans.
Portfolio loans increased $948 million, or 30%, from December 31, 2016. Of this increase, $270 million, or 9%,

32

was organic loan growth and $678 million was from the acquisition of JCB. See Item 8, Note 5 – Portfolio
Loans for more information.

• Deposits – Total deposits at December 31, 2017 were $4.2 billion, an increase of $923 million, or 29%, from
December 31, 2016. The acquisition of JCB contributed $774 million of this increase. Core deposits, defined as
total deposits excluding time deposits, were $3.6 billion at December 31, 2017, an increase of $817.4 million, or
29.6% largely due to the JCB acquisition ($636 million) and the continued progress across our regions and business
lines.

• Asset quality – Nonperforming assets were $16.2 million at December 31, 2017, an increase of 2% compared to
$15.9 million at December 31, 2016. Nonperforming assets represented 0.31% of total assets at December 31,
2017, compared to 0.39% of total assets at December 31, 2016. 

Provision for portfolio loan losses was $10.8 million in 2017, compared to $5.6 million in 2016. The Company
experienced higher levels of charge-offs in 2017 in contrast to 2016, in addition to a reduction of recoveries in
2017 compared to 2016. See Item 8, Note 5 – Portfolio Loans, and Provision and Allowance for Loan Losses in
this section for more information.

RESULTS OF OPERATIONS
Net Interest Income
Average Balance Sheet
Non-core acquired loans were those acquired from the FDIC and were previously covered by shared-loss
agreements. These loans continue to be accounted for as purchased credit impaired loans. Approximately $44
million of loans acquired from JCB's portfolio are also accounted for as purchased credit impaired loans. However,
all loans acquired from JCB are included in portfolio loans. The following table presents, for the periods indicated,
certain information related to our average interest-earning assets and interest-bearing liabilities, as well as, the
corresponding interest rates earned and paid, all on a tax equivalent basis.

Comparison of 2017 and 2016
Net interest income (on a tax equivalent basis) was $179.1 million for 2017, compared to $137.3 million for 2016, an
increase of $41.9 million, or 30%. Total interest income increased $53.4 million and total interest expense increased
$11.5 million. The tax-equivalent net interest margin was 3.88% for 2017, compared to 3.84% for the prior year period.
The increase in net interest income was primarily due to the impact of rising interest rates which increased yields on
variable rate loans and to an improved earning asset mix combined with the acquisition of JCB, partially offset by a
decline in contributions from non-core acquired assets and higher rates on interest bearing liabilities.

Average interest-earning assets increased $1 billion, or 29%, to $4.6 billion for the year ended December 31, 2017.
Average total loans increased $872 million, or 29%, to $3.9 billion for the year ended December 31, 2017, from $3.0
billion for the year ended December 31, 2016, largely due to the JCB acquisition along with organic loan growth.
Average securities and short-term investments increased $169 million, or 29%, to $760.8 million for 2017 compared

35

  
 
to $591.7 million for 2016. Interest income on earning assets increased $38.2 million due to an increase in volume,
which includes an offsetting $5.6 million decrease from the decline in non-core acquired loans as the balances continue
to run off. Excluding non-core acquired loans, total interest income increased $43.8 million due to volume, primarily
from portfolio loans. Interest income on earnings assets increased $15.2 million due to rising interest rates. 

For the year ended December 31, 2017, average interest-bearing liabilities increased $762 million, or 29%, to $3.4
billion,  compared  to  $2.6  billion  for  the  year  ended  December 31,  2016. The  increase  in  average  interest-bearing
liabilities resulted from a $612 million increase in average interest-bearing deposits, a $52 million increase in average
subordinated debentures and notes, an $83 million increase in FHLB advances, and a $15 million increase in average
other borrowed funds. Average interest-bearing deposits increased from the JCB acquisition, and our continued progress
across our regions and business lines. The issuance of $50 million of subordinated notes on November 1, 2016 increased
the average balance of subordinated debentures and notes for 2017 compared to 2016. Average other borrowed funds
increased due to higher balances in customer repurchase agreements. For the year ended December 31, 2017, interest
expense on interest-bearing liabilities increased $6.0 million due to higher rates from market conditions, and $5.5
million due to higher volumes, compared to the same period in 2016.

The Company continues to manage its balance sheet to grow core net income1 and expects to maintain core net interest
margin1 over the coming quarters; however, pressure on funding costs could negate the expected trends in core net
interest margin1.

Comparison of 2016 and 2015 
Net interest income (on a tax equivalent basis) was $137.3 million for 2016, compared to $122.1 million for 2015, an
increase of $15.1 million, or 12%. Total interest income increased $16.5 million and total interest expense increased
$1.4 million.

Average interest-earning assets increased $406.8 million, or 13%, to $3.6 billion for the year ended December 31,
2016. Average loans increased $364.9 million, or 14%, to $3.0 billion for the year ended December 31, 2016, from
$2.6 billion for the year ended December 31, 2015, largely due to strong portfolio growth in 2016, including growth
in all major categories excluding non-core acquired loans. Average securities and short-term investments increased
$42.0 million, to $591.7 million from 2015. Interest income on earning assets increased $9.9 million due to an increase
in volume, which excludes an offsetting $7.8 million decrease from the decline in non-core acquired loans as the
balances continue to run off. Excluding non-core acquired loans, total interest income increased $17.6 million due to
volume, primarily from portfolio loans. Interest income on earnings assets increased $6.6 million due to changes in
interest rates, largely from non-core acquired loans. 

For the year ended December 31, 2016, average interest-bearing liabilities increased $289.8 million, or 12%, to $2.6
billion,  compared  to  $2.3  billion  for  the  year  ended  December 31,  2015. The  increase  in  average  interest-bearing
liabilities resulted from a $142.0 million increase in average money market accounts and savings accounts, and a $94.6
million increase in interest-bearing transaction accounts. The significant increase in money market and saving accounts
was due to the Company's enhanced focus on deposit gathering in both commercial and business banking. For the year
ended December 31, 2016, interest expense on interest-bearing liabilities increased $0.6 million due to higher rates
from market conditions, and $0.8 million due to higher volumes, including increased borrowings from the FHLB and
the subordinated notes issuance, versus the same period in 2015.

1On December 7, 2015, the Company entered into an agreement with the FDIC to terminate all existing loss share agreements
associated with the assets and assumption of liabilities acquired in four FDIC-assisted transactions from 2009 through 2011.

Non-core acquired loans contributed $5.0 million, $9.3 million, and $4.6 million of net income for the years ended
December 31,  2017,  2016,  and  2015,  respectively. At  December 31,  2017,  the  remaining  accretable  yield  on  the
portfolio was estimated to be $10 million, and the non-accretable difference was $13 million. The Company estimates
2018 income from accelerated cash flows and other incremental accretion to be between $3 million and $5 million.

Noninterest income increased $5.3 million, or 18%, in 2017 compared to 2016. Core noninterest income1 increased
$7.6 million, or 28%, in 2017. This improvement was primarily due to higher income from deposit service charges,
wealth management revenue, and card services from the acquisition of JCB, as well as growth in the client base. This
income growth was partially offset by lower gains on the sale of other real estate, which declined $1.7 million from
2016. Noninterest income increased $8.4 million, or 41%, in 2016 compared to 2015. The increase was largely due to
an increase in the gain on sale of other real estate from non-core acquired loans of $1.5 million, and a decrease in the
loss from the change in FDIC loss share receivable of $5.0 million.

The Company expects continued growth in fee income of 5% - 7% for 2018.

(1) A non-GAAP measure.  A reconciliation has been included in this MD&A section under the caption "Use of Non-GAAP Financial
Measures."

Noninterest expenses increased $28.9 million, or 34%, in 2017 compared to the prior period. Excluding non-comparable
items, core noninterest expenses1 increased $25.7 million, or 31%. This increase primarily represents the additional
operating and run-rate expenses associated with JCB, as well as continued investments in underlying business growth.
Other core noninterest expense includes $1.4 million of tax credit investment amortization. These investments have a
corresponding and higher benefit in the Company's income tax expense line and were consistent with the Company's
overall tax planning efforts. Noninterest expenses increased $3.9 million, or 5%, in 2016 compared to 2015, partially
due to $1.4 million of merger related expenses for the JCB acquisition and $1.0 million for a facilities disposal charge
from lease buyouts of two unused facilities.

The Company expects to continue to invest in revenue producing associates and other infrastructure that supports
additional growth during 2018. These investments are expected to result in expense growth, at a rate of 35% - 45%
of projected revenue growth for 2018, resulting in modest improvement to the Company's efficiency ratio.

Income Taxes

On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax
Cuts and Jobs Act (the "Tax Act"). The Tax Act made broad and complex changes to the U.S. tax code, including, but
not limited to, (1) reducing the U.S. federal corporate tax rate from 35% to 21%; (2) requiring companies to pay a one-
time transition tax on certain unrepatriated earnings of foreign subsidiaries; (3) generally eliminating U.S. federal
income taxes on dividends from foreign subsidiaries; (4) requiring a current inclusion in U.S. federal taxable income
of certain earnings of controlled foreign corporations; (5) eliminating the corporate alternative minimum tax (AMT)
and changing how existing AMT credits can be realized; (6) creating the base erosion anti-abuse tax (BEAT), a new

39

minimum tax; (7) creating a new limitation on deductible interest expense; and (8) changing rules related to uses and
limitations of net operating loss carryforwards created in tax years beginning after December 31, 2017.

In connection with our initial analysis of the impact of the Tax Act, we have recorded a net tax expense of $12.1 million
in the period ending December 31, 2017. This net expense represents a revaluation of the Company's DTA for the
corporate tax rate reduction. 

In 2017, the Company recorded income tax expense of $38.3 million on pre-tax income of $86.5 million, resulting in
an effective tax rate of 44.3%. The Company's effective tax rate was significantly higher than 2016 due to the DTA
revaluation charge of $12.1 million to income tax expense and increased pre-tax earnings. These increases reduced
the savings impact of permanent items. The following items impacted the 2017 effective tax rate:

•
•

tax credit investments made in the year yielded $1.6 million of federal tax credits, and
change in accounting standards resulted in $2.1 million of excess tax benefits on stock awards.

As a result of the new 21% corporate federal income tax rate, the Company expects its effective tax rate in 2018 to
be approximately 17% - 19% with a 2% -3% lower rate in the first quarter expected due to the effect of vesting of
employee stock awards.

In 2016, the Company recorded income tax expense of $26.0 million on pre-tax income of $74.8 million, resulting in
an effective tax rate of 34.7%. The Company's effective tax rate was slightly higher than 2015 as pre-tax income was
significantly higher, reducing the savings impact of permanent items. The following items impacted the 2016 effective
tax rate:
•
•

interest income on tax exempt mortgages and municipal bonds of $1.0 million, and
decrease in the tax rate used for deferred tax assets of $0.3 million.

In 2015, the Company recorded income tax expense of $20.0 million on pre-tax income of $58.4 million, resulting in
an effective tax rate of 34.2%. The following items impacted the 2015 effective tax rate:

•
•

interest income on tax exempt mortgages and municipal bonds of $1.0 million, and
release of reserves for uncertain tax positions due to remeasurement of $0.4 million.

Assets
Loans by Type
The Company has a diversified loan portfolio, with no particular concentration of credit in any one economic sector;
however, a substantial portion of the portfolio, including the C&I category, is secured by real estate. The ability of the
Company's borrowers to honor their contractual obligations is partially dependent upon the local economy and its
effect on the real estate market.

C&I loans are made based on the borrower's ability to generate cash flows for repayment from income sources, general
credit strength, experience, and character, even though such loans may also be secured by real estate or other assets.
The credit risk related to commercial loans is largely influenced by general economic conditions and the resulting
impact on a borrower's operations.

Real estate loans are also based on the borrower's character, but more emphasis is placed on the estimated cash flows
from the operation of the property, or the underlying collateral values, or both.

At December 31, 2017, $332.4 million, or 24%, of the commercial real estate loans were owner-occupied by commercial
and industrial businesses where the primary source of repayment is dependent on sources other than the underlying
collateral. Multifamily and other commercial properties on which income from the property is the primary source of
repayment represent the balance of this category and are located within our St. Louis, Kansas City, and Phoenix markets.
These loans are underwritten based on the cash flow coverage of the property, the Company's loan to value guidelines,
and generally require either the limited or full guaranty of principal sponsors of the credit.

Real estate construction loans, relating to residential and commercial properties, represent financing secured by real
estate under development for eventual sale or undeveloped ground. $74.5 million of these loans include the use of
interest reserves and follow standard underwriting guidelines. Construction projects are monitored by the loan officer
and a centralized independent loan disbursement function is employed.

Residential real estate loans include residential mortgages, which are loans that, due to size or other attributes, do not
qualify for conventional home mortgages available for sale in the secondary market, second mortgages and home
equity lines. Residential mortgage loans are usually limited to a maximum of 80% of collateral value.

41

 
Consumer and other loans represent loans to individuals, loans to state and political subdivisions, loans to nondepository
financial institutions, and loans to purchase or are fully secured by investment securities. Credit risk is managed by
thoroughly reviewing the creditworthiness of the borrowers prior to origination and thereafter.

The Company continues to focus on originating high-quality C&I relationships as they typically have variable interest
rates and allow for cross selling opportunities involving other banking products. For the period ending December 31,
2017, C&I loans increased $286 million, or 18% from 2016. C&I loan growth also supports our efforts to maintain
the Company's asset sensitive interest rate risk position. Additionally, our specialized products, especially Enterprise
value lending, Life insurance premium financing, and Tax credit financing/lending, consist of primarily C&I loans,
and  have  contributed  significantly  to  the  Company's  loan  growth.  These  loans  are  sourced  through  relationships
developed with wealth and estate planning firms and private equity funds, and are not bound geographically by our
three markets with branch facilities. As a result, these specialized loan products offer opportunities to expand and
diversify our overall geographic concentration by entering into new markets.

The Enterprise value lending portfolio comprised 21% of the C&I category as of December 31, 2017. This portfolio
primarily consists of loans in the manufacturing sector. As of December 31, 2017, the average outstanding balance of
individual loans in this category was $4.3 million. The largest relationships within this category were a $15.6 million
relationship in the  administrative and support services sector and a $14.0 million relationship in the trucking industry.

2018 portfolio loan growth is expected to be approximately 7% - 9%.

The following descriptions focus on portfolio loans at December 31, 2017, and exclude non-core acquired loans.

The commercial and industrial category represents $1.9 billion, or 47%, of portfolio loans. This category includes
$615.6 million in loans secured by accounts receivable, inventory and equipment, $407.6 million from the Enterprise
value lending portfolio, and $364.9 million in Life insurance premium financing. These loans consist of over 1100
relationships with an average outstanding balance of $1.8 million. The largest loans within this category are a $22.7
million term loan secured by accounts receivable and inventory and a $19.5 million term loan secured by life insurance
premium financing within the St. Louis region.

The largest loans within the investor owned commercial real estate portfolio are retail and commercial office permanent
loans. The Company had $246.9 million of investor owned permanent loans secured by retail properties. There were
121 loan relationships in this category with an average outstanding loan balance of $2.0 million. The largest loans
outstanding at year end were a $13.3 million loan secured by a multi-tenant retail center in Phoenix, an $11.9 million
loan secured by commercial land in the St. Louis area, and an $11.0 million loan secured by a hotel in Pennsylvania.

43

The Company had $234.7 million of investor owned permanent loans secured by commercial office properties. There
were 94 loan relationships with an average outstanding loan balance of $2.5 million. The largest loans outstanding at
year end were a $20.2 million loan secured by a multi-tenant office building in the St. Louis area, a $17.4 million loan
secured by a multi-tenant office condominium complex in Phoenix, and a $13.8 million loan secured by a multi-tenant
office building in the Kansas City region.

The largest loans within the owner occupied commercial real estate portfolio are commercial and industrial loans. The
Company had $318.2 million of owner occupied loans secured by commercial and industrial properties. There were
345 loan relationships in this category with an average outstanding loan balance of $0.9 million. The largest loans
outstanding at year end were a $9.8 million loan secured by an industrial building in Texas, a $8.8 million loan secured
by an office building in Kansas, and an $7.3 million loan secured multi-tenant office building in Arizona.

Significant loan concentrations are considered to exist for a financial institution when there are amounts loaned to
numerous borrowers engaged in similar activities that would cause them to be similarly impacted by economic or other
conditions.  At December 31, 2017, no significant concentrations exceeding 10% of total loans existed in the Company's
loan portfolio, except as described above.

(1) Loan balances are net of unearned loan fees.

(2) Not adjusted for impact of interest rate swap agreements.

(3) Fixed rate loans include variable rate loans with a rate floor that are currently accruing interest at the floor.

Fixed rate loans comprise 46% of the loan portfolio at December 31, 2017, and 54% of the Company's loans are
variable rate loans, most of which are based on the prime rate or the LIBOR. The prime rate increased three times
throughout 2017. In December 2017, the Federal Reserve raised the targeted Fed Funds rate 25 basis points from 1.25%
to 1.50% resulting in a prime rate of 4.50% compared to 3.75% in December 2016. Most loan originations have one
to three year maturities. Management monitors this mix as part of its interest rate risk management. See "Interest Rate
Risk" of this MD&A section.

Of the $479.7 million of commercial real estate loans maturing in one year or less, $288.9 million, or 60%, represent
loans secured by non-owner occupied commercial properties.

The provision for loan losses on portfolio loans for the year ended December 31, 2017 was $10.8 million, compared
to $5.6 million, and $4.9 million for the comparable 2016 and 2015 periods, respectively. The provision for loan losses
for the years ended December 31, 2017 and 2016 was primarily to provide for net charge-offs incurred on impaired
loans, as well as organic loan growth in the portfolio.

The allowance for portfolio loan losses was 0.95% of portfolio loans at December 31, 2017, compared to 1.20%, and
1.22%, at December 31, 2016 and 2015, respectively. Management believes the allowance for loan losses is adequate
to absorb inherent losses in the loan portfolio. 

For PCI loans, the Company remeasures contractual and expected cash flows periodically. When the re-measurement
process results in a decrease in expected cash flows, typically due to an increase in expected credit losses, impairment
is recorded through provision for loan losses. Similarly, when expected credit losses decrease in the re-measurement
process, prior recorded impairment is reversed before the yield is increased prospectively. The provision reversal on
PCI loans for the year ended December 31, 2017 was $0.6 million, compared to provision reversal of $1.9 million,
and expense of $4.4 million for the comparable 2016 and 2015 periods, respectively.  

Nonperforming assets
Nonperforming loans are defined as loans on non-accrual status, loans 90 days or more past due but still accruing
interest, and restructured loans. Restructured loans involve the granting of a concession to a borrower due to their
financial difficulty and include modification of terms of the loan, such as changes in payment schedule or interest rate.
Nonperforming assets include nonperforming loans plus other real estate. 

Nonperforming loans exclude PCI loans. PCI loans are accounted for on a pool basis, and the pools are considered to
be performing. See Item 8, Note 5 – Loans for more information.

The Company's nonperforming loans meet the definition of “impaired loans” in accordance with U.S. GAAP.

Nonperforming loans at December 31, 2017 increased $0.8 million, or 5%, when compared to December 31, 2016.
Other principal reductions of $7.4 million includes $1.8 million of proceeds received from sales of collateral, $4.6
million of payments received from borrowers, and $1.0 million of proceeds from other loan settlements. 

At December 31, 2017, nonperforming loans were comprised of primarily three relationships with the largest being a
$5.4 million C&I relationship, which represented 34% of nonperforming loans. Approximately 42% of nonperforming
loans were related to the Company's specialized lending products, 19% were located in the St. Louis market, and 37%
were located in the Kansas City market. At December 31, 2017, there were two performing restructured loans, or one
relationship,  that  were  excluded  from  nonperforming  loans  in  the  amount  of  $1.5  million.  Nonperforming  loans
represented 0.39% of portfolio loans at December 31, 2017, versus 0.48% at December 31, 2016.

At December 31, 2016, nonperforming loans were comprised of 11 relationships with the largest being a $9.8 million
C&I relationship, which represented 66% of nonperforming loans. Approximately 91% of nonperforming loans were
related to the Company's specialized lending products, 6% were located in the St. Louis market and 3% in the Kansas
City  market.  At  December 31,  2016,  there  were  three  performing  restructured  loans  that  were  excluded  from
nonperforming loans in the amount of $1.9 million. Nonperforming loans represented 0.48% of portfolio loans at
December 31, 2016, versus 0.34% at December 31, 2015.

Potential problem loans
Potential problem loans are unimpaired loans with a risk rating of 8-Substandard still accruing interest. See Item 8,
Note  5  –  Portfolio  Loans  for  the  definitions  of  risk  ratings.  Potential  problem  loans,  which  are  not  included  in
nonperforming loans, were $59.4 million, or 1.5%, of portfolio loans outstanding at December 31, 2017, compared to
$77.6 million, or 2.5%, of portfolio loans outstanding at December 31, 2016. For these loans, payment of principal
and interest is current and the loans are performing, however some doubts exist as to the borrower's ability to continue
to  comply  with  repayment  terms.  Potential  problem  loans  include  loans  to  companies  that  are  characterized  by
significant losses or where downward trends in financial performance have been identified, or are in an industry that
is experiencing significant difficulty.

Other real estate
Other real estate at December 31, 2017 was $0.5 million, compared to $1.0 million, at December 31, 2016. In 2015,
$5.1 million of other real estate previously covered under FDIC loss share agreements was reclassified into other real
estate due to termination of the Company's loss share agreements with the FDIC in the fourth quarter of 2015.

At December 31, 2017, other real estate was comprised of one commercial real estate property, or 45%, located in the
Kansas City region, and one residential property, or 55%, located in the St. Louis region.

The writedowns in fair value were recorded in loan, legal, and other real estate expense. For the year ended December 31,
2017, the Company realized a net gain of $0.1 million compared to $1.8 million in 2016 on the sale of other real estate
and recorded these gains as part of noninterest income.

Investments
At December 31, 2017, our portfolio of investment securities was $715 million, or 14%, of total assets. The portfolio
is primarily comprised of agency mortgage-backed securities, obligations of U.S. Government-sponsored enterprises,
as well as municipal bonds. The portfolio is comprised of both available for sale and held to maturity securities.

Other investments, at cost, per the consolidated balance sheets, primarily consist of the FHLB capital stock, common
stock  investments  related  to  our  trust  preferred  securities,  and  other  investments  in  Small  Business  Investment
Companies ("SBICs"). At December 31, 2017, of the $12.9 million in FHLB capital stock, $6.0 million is required for
FHLB membership and $6.9 million is required to support our outstanding advances. Historically, it has been the
FHLB's practice to automatically repurchase activity-based stock that became excess because of a member's reduction
in advances. The FHLB has the discretion, but is not required, to repurchase any shares a member is not required to
hold.

An increase in deposits from 2016 to 2017 occurred in all areas except brokered certificates of deposit which experienced
a slight decline. Core deposits, defined as total deposits excluding time deposits, were $3.6 billion at December 31,
2017, an increase of $817 million, or 30%, from the prior year period. The increase in deposits reflects the acquisition
of JCB, and continued progress across the Company's regions and business lines.

Liquidity and Capital Resources

Liquidity
The objective of liquidity management is to ensure we have the ability to generate sufficient cash or cash equivalents
in a timely and cost-effective manner to meet our commitments as they become due. Typical demands on liquidity are
changes in deposit levels, maturing time deposits which are not renewed, and fundings under credit commitments to
customers.  Funds  are  available  from  a  number  of  sources,  such  as  the  core  deposit  base  and  loans  and  securities
repayments and maturities.  

Additionally, liquidity is provided from lines of credit with correspondent banks, the Federal Reserve and the FHLB,
the ability to acquire large and brokered deposits, sales of the securities portfolio, and the ability to sell loan participations
to  other  banks. These  alternatives  are  an  important  part  of  our  liquidity  plan  and  provide  flexibility  and  efficient
execution of the asset-liability management strategy.

The  Bank's Asset-Liability  Management  Committee  oversees  our  liquidity  position,  the  parameters  of  which  are
approved by the Bank's Board of Directors. Our liquidity position is monitored monthly by producing a liquidity report,
which measures the amount of liquid versus non-liquid assets and liabilities. Our liquidity management framework
includes measurement of several key elements, such as the loan to deposit ratio, a liquidity ratio, and a dependency
ratio. The Company's liquidity framework also incorporates contingency planning to assess the nature and volatility
of  funding  sources  and  to  determine  alternatives  to  these  sources.  While  core  deposits  and  loan  and  investment
repayments are principal sources of liquidity, funding diversification is another key element of liquidity management
and is achieved by strategically varying depositor types, terms, funding markets, and instruments.

For the year ended December 31, 2017, net cash used by investing activities was $312.4 million, versus net cash used
of $358.1 million in 2016. The investing activities in 2017 primarily represents our normal business activity of making
loans and investing in securities. Net cash provided by financing activities was $221.2 million in 2017, versus net cash
provided of $380.2 million in 2016. The change in cash provided by financing activities was primarily due to larger
increases in deposit accounts and the issuance of $50 million of subordinated notes both in 2016, partially offset by
an increase in net proceeds from FHLB advances in 2017.

Strong capital ratios, credit quality and core earnings are essential to retaining cost-effective access to the wholesale
funding markets. Deterioration in any of these factors could have a negative impact on the Company's ability to access
these funding sources and, as a result, these factors are monitored on an ongoing basis as part of the liquidity management

52

process. The Bank is subject to regulations and, among other things, may be limited in its ability to pay dividends or
transfer funds to the parent company.  Accordingly, consolidated cash flows as presented in the consolidated statements
of cash flows may not represent cash immediately available for the payment of cash dividends to the Company's
shareholders or for other cash needs.

Parent Company liquidity
The parent company's liquidity is managed to provide the funds necessary to pay dividends to shareholders, service
debt,  invest  in  subsidiaries  as  necessary,  and  satisfy  other  operating  requirements. The  parent  company's  primary
funding sources to meet its liquidity requirements are dividends and payments from the Bank and proceeds from the
issuance of equity (i.e. stock option exercises, stock offerings). Another source of funding for the parent company
includes the issuance of subordinated debentures and other debt instruments.

The Company has an effective shelf registration statement on Form S-3 registering up to $100 million of common
stock, preferred stock, debt securities, and various other securities, including combinations of such securities. The
Company's  ability  to  offer  securities  pursuant  to  the  registration  statement  depends  on  market  conditions  and  the
Company's continuing eligibility to use the Form S-3 under rules of the SEC.

On November 1, 2016, the Company issued $50 million aggregate principal amount of 4.75% fixed-to-floating rate
subordinated notes with a maturity date of November 1, 2026, which initially bear an annual interest rate of 4.75%,
with interest payable semiannually. Beginning November 1, 2021, the interest rate resets quarterly to the three-month
LIBOR rate plus a spread of 338.7 basis points, payable quarterly.  

The Company has a senior unsecured revolving credit agreement (the "Revolving Agreement") with another bank
allowing for borrowings up to $20 million which is renewed through February 2019. The proceeds can be used for
general corporate purposes. The Revolving Agreement is subject to ongoing compliance with a number of customary
affirmative and negative covenants as well as specified financial covenants. As of December 31, 2017, there were no
outstanding balances under the Revolving Agreement. 

The Bank has historically provided a dividend to supplement the parent company's liquidity at the discretion of the
Bank's management. The Bank paid dividends of $20.0 million, $7.5 million, and $10.0 million throughout 2017,
2016, and 2015, respectively. The parent company's cash balance as of December 31, 2017 was $10.0 million, a $42.3
million decrease from December 31, 2016, primarily due to cash used for the acquisition of JCB. Management believes
the current level of cash at the holding company will be sufficient to meet all projected cash needs for at least the next
year.

As of December 31, 2017, the Company had $69.2 million of outstanding subordinated debentures as part of 10 Trust
Preferred Securities Pools. These securities are classified as debt but are included in regulatory capital and the related
interest expense is tax-deductible, which makes them an attractive source of funding.

Regulations issued by the Federal Reserve Board under the Basel III regulatory capital reforms allow our currently
outstanding trust preferred securities to retain tier 1 capital status.

Bank liquidity
The Bank has a variety of funding sources available to increase financial flexibility. In addition to amounts currently
borrowed, at December 31, 2017, the Bank could borrow an additional $484.7 million from the FHLB of Des Moines
under blanket loan pledges and has an additional $898.1 million available from the Federal Reserve Bank under a
pledged loan agreement. The Bank has unsecured federal funds lines with five correspondent banks totaling $75.0
million. 

Investment securities are another important tool to the Bank's liquidity objectives. Securities totaled $715.1 million at
December 31, 2017, and included $500.0 million that was pledged as collateral for deposits of public institutions,
treasury, loan notes, and other requirements. The remaining $215.1 million could be pledged or sold to enhance liquidity,
if necessary.

53

In the normal course of business, the Bank enters into certain forms of off-balance sheet transactions, including unfunded
loan commitments and letters of credit. These transactions are managed through the Bank's various risk management
processes. Management considers both on-balance sheet and off-balance sheet transactions in its evaluation of the
Company's  liquidity.  The  Bank  has  $1.4  billion  in  unused  commitments  as  of  December 31,  2017.  While  this
commitment  level  would  exhaust  the  majority  the  Company's  current  liquidity  resources,  the  nature  of  these
commitments is such that the likelihood of funding them in the aggregate at any one time is low.

Capital Resources
The Company and the Bank are subject to various regulatory capital requirements administered by the Federal banking
agencies.  Failure  to  meet  minimum  capital  requirements  can  initiate  certain  mandatory  and  possible  additional
discretionary actions by regulators that, if undertaken, could have a direct material effect on the financial statements.
Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and its
bank affiliate must meet specific capital guidelines that involve quantitative measures of assets, liabilities, and certain
off-balance-sheet items as calculated under regulatory accounting practices. The banking affiliate’s capital amounts
and classification are also subject to qualitative judgments by the regulators about components, risk weightings and
other factors.

Quantitative measures established by regulation to ensure capital adequacy require the Company and the Bank to
maintain minimum amounts and ratios (set forth in the following table) of total and tier 1 capital to risk-weighted
assets, and of tier 1 capital to average assets. To be categorized as “well capitalized”, banks must maintain minimum
total risk-based (10%), tier 1 risk-based (8%), common equity tier 1 risk-based (6.5%), and tier 1 leverage ratios (5%).
As of December 31, 2017, and December 31, 2016, the Company and the Bank met all capital adequacy requirements
to which they are subject.

The Bank met the definition of “well capitalized” at December 31, 2017, 2016, and 2015. Refer to Item 8 - Note 14
Regulatory Matters for a summary of our risk-based capital and leverage ratios.

The following table summarizes the Company's various capital ratios at the dates indicated:

Risk Management
Market risk arises from exposure to changes in interest rates and other relevant market rate or price risk. The Company
faces market risk in the form of interest rate risk through transactions other than trading activities. Market risk from
these activities, in the form of interest rate risk, is measured and managed through a number of methods. The Company
uses financial modeling techniques to measure interest rate risk. These techniques measure the sensitivity of future
earnings due to changing interest rate environments. Guidelines established by the Bank's Asset/Liability Management
Committee and approved by the Bank's Board of Directors are used to monitor exposure of earnings at risk. General
interest rate movements are used to develop sensitivity as management believes it has no primary exposure to a specific
point on the yield curve. These limits are based on the Company's exposure to immediate and sustained parallel rate
movements up to 400 basis points, either upward or downward. 

Interest Rate Risk 
Our  interest  rate  risk  management  practices  are  aimed  at  optimizing  net  interest  income,  while  guarding  against
deterioration that could be caused by certain interest rate scenarios. Interest rate sensitivity varies with different types
of interest-earning assets and interest-bearing liabilities. We attempt to maintain interest-earning assets, comprised
primarily of both loans and investments, and interest-bearing liabilities, comprised primarily of deposits, maturing or
repricing in similar time horizons in order to manage any impact from market interest rate changes according to our
risk tolerance. The Company uses an earnings simulation model to measure earnings sensitivity to changing rates. 

The Company determines the sensitivity of its short-term future earnings to a hypothetical plus or minus 100 to 300
basis point parallel rate shock through the use of simulation modeling. The simulation of earnings includes the modeling
of  the  balance  sheet  as  an  ongoing  entity.  Future  business  assumptions  involving  administered  rate  products,
prepayments for future rate-sensitive balances, and the reinvestment of maturing assets and liabilities are included.
These items are then modeled to project net interest income based on a hypothetical change in interest rates. The
resulting net interest income for the next 12-month period is compared to the net interest income amount calculated
using flat rates. This difference represents the Company's earnings sensitivity to a positive or negative 100 basis points
parallel rate shock.

The following table summarizes the expected impact of interest rate shocks on net interest income (due to the current
level of interest rates, the 200 and 300 basis point downward shock scenarios are not shown):

Rate Shock

+ 300 bp

+ 200 bp

+ 100 bp

 - 100 bp

Annual % change
in net interest income

3.9%

2.7%

1.4%

-5.9%

In addition to the rate shocks shown in the table above, the Company models net interest income under various dynamic
interest rate scenarios. In general, changes in interest rates are positively correlated with changes in net interest income.
The exception to this is a bear flattener scenario (short term rates move up more than long term rates), which results
in a mild decrease in net interest income.

The Company occasionally uses interest rate derivative financial instruments as an asset/liability management tool to
hedge mismatches in interest rate exposure indicated by the net interest income simulation described above. They are
used to modify the Company's exposures to interest rate fluctuations and provide more stable spreads between loan
yields and the rate on their funding sources. At December 31, 2017, the Company had no derivative contracts used to
manage interest rate risk. Derivative financial instruments are also discussed in Item 8, Note 6 – Derivative Financial
Instruments.

55

Contractual Obligations, Off-Balance Sheet Risk, and Contingent Liabilities
Through the normal course of operations, the Company has entered into certain contractual obligations and other
commitments. Such obligations relate to funding of operations through deposits or debt issuances, as well as leases
for premises and equipment. As a financial services provider, the Company routinely enters into commitments to extend
credit. While  contractual  obligations  represent  future  cash  requirements  of  the  Company,  a  significant  portion  of
commitments to extend credit may expire without being drawn upon. Such commitments are subject to the same credit
policies and approval process accorded to loans made by the Company.

The required contractual obligations and other commitments, excluding any contractual interest1, at December 31,
2017, were as follows:

(1) Interest charges on related contractual obligations were excluded from reported amounts as the potential cash outflows would have
corresponding cash inflows from interest-earning assets.

(2) Represents the estimated timing of various capital raises for SBICs.

As of December 31, 2017, we had liabilities associated with uncertain tax positions of $0.8 million. The table above
does not include these liabilities due to the high degree of uncertainty regarding the future cash flows associated with
these amounts.

The Company also enters into derivative contracts under which the Company either receives cash from or pays cash
to counterparties depending on changes in interest rates. Derivative contracts are carried at fair value on the consolidated
balance sheet with the fair value representing the net present value of expected future cash receipts or payments based
on market interest rates as of the balance sheet date. The fair value of these contracts changes daily as market interest
rates change.

CRITICAL ACCOUNTING POLICIES 
The following accounting policies are considered most critical to the understanding of the Company's financial condition
and  results  of  operations.  These  critical  accounting  policies  require  management's  most  difficult,  subjective  and
complex judgments about matters that are inherently uncertain. Because these estimates and judgments are based on
current circumstances, they may change over time or prove to be inaccurate based on actual experiences. In the event
that different assumptions or conditions were to prevail, and depending upon the severity of such changes, the possibility
of a materially different financial condition and/or results of operations could reasonably be expected. The impact and
any associated risks related to our critical accounting policies on our business operations are discussed throughout
“Management's Discussion and Analysis of Financial Condition and Results of Operations,” where such policies affect
our reported and expected financial results. For a detailed discussion on the application of these and other accounting
policies, see Item 8, Note 1 – Summary of Significant Accounting Policies.

The Company has prepared all of the consolidated financial information in this report in accordance with U.S. GAAP.
The Company makes estimates and assumptions that affect the reported amount of assets and liabilities, disclosure of
contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of revenue
and expenses during the reporting period. Such estimates include the valuation of loans, goodwill, intangible assets,
and other long-lived assets, along with assumptions used in the calculation of income taxes, among others. These
estimates and assumptions are based on management's best estimates and judgment. Management evaluates its estimates
and assumptions on an ongoing basis using historical experience and other factors, including the current economic
environment, which management believes to be reasonable under the circumstances. We adjust such estimates and
assumptions when facts and circumstances dictate. Decreased real estate values, volatile credit markets, and persistent
high unemployment have combined to increase the uncertainty inherent in such estimates and assumptions. As future
events  and  their  effects  cannot  be  determined  with  precision,  actual  results  could  differ  significantly  from  these
estimates. Changes in estimates resulting from continuing changes in the economic environment will be reflected in
the financial statement in future periods. There can be no assurances that actual results will not differ from those
estimates.

Acquisitions
Acquisitions and Business Combinations are accounted for using the acquisition method of accounting. The assets and
liabilities of the acquired entities have been recorded at their estimated fair values at the date of acquisition. Goodwill
represents the excess of the purchase price over the fair value of net assets acquired, including the amount assigned
to identifiable intangible assets. 

The purchase price allocation process requires an estimation of the fair values of the assets acquired and the liabilities
assumed. When a business combination agreement provides for an adjustment to the cost of the combination contingent
on  future  events,  the  Company  includes  an  estimate  of  the  acquisition-date  fair  value  as  part  of  the  cost  of  the
combination. To determine the fair values, the Company relies on third party valuations, such as appraisals, or internal
valuations based on discounted cash flow analyses or other valuation techniques. The results of operations of the
acquired  business  are  included  in  the  Company's  consolidated  financial  statements  from  the  respective  date  of
acquisition. Merger-related costs are costs the Company incurs to effect a business combination. In 2017, the Company
changed its presentation of Merger related expenses as a separate component of Noninterest expenses on the Condensed
Consolidated Statements of Operations. Merger related expenses include costs directly related to merger or acquisition
activity and include legal and professional fees, system consolidation and conversion costs, and compensation costs
such as severance and retention incentives for employees impacted by acquisition activity. The Company accounts for
merger-related costs as expenses in the periods in which the costs are incurred and the services are received.

Allowance for Loan Losses
The Company maintains an allowance for loan losses (“the allowance”), which is management's estimate of probable,
inherent losses in the outstanding loan portfolio. The allowance is based on management's continuous review and
evaluation of the loan portfolio. The review and evaluation combines several factors including: consideration of loan
loss experience; trends in past due and nonperforming loans; changes in lending policies and procedures; existing
business and economic conditions; the fair value of underlying collateral; changes in the nature and volume of the
Company's loan portfolio; changes in the lending department of the Company; volume and severity of past due loans;

57

the quality of the loan review system; concentrations of credit and other qualitative and other factors which affect
probable credit losses. Because current economic conditions can change and are difficult to predict, the anticipated
amount of estimated loan losses, and therefore the adequacy of the allowance, could change significantly.

In determining the allowance and the related provision for loan losses for portfolio loans, three principal elements are
considered: 
1)
2) allocations based principally on the Company's risk rating formulas, and
3) a qualitative adjustment based on other economic, environmental and portfolio factors.

specific allocations based upon probable losses identified during a quarterly review of the loan portfolio,

The first element reflects management's estimate of probable losses based upon a systematic review of specific loans
considered to be impaired. These estimates are based upon discounted cash flows as estimated and used to assign loss
or collateral exposure, if they are collateral dependent for collection. 

The second element reflects the application of our loan rating system. Loans are rated and assigned a loss allocation
factor for each category based on a loss migration analysis using the Company's loss experience over the last six years.
The higher the rating assigned to a loan, the greater the loss allocation percentage applied. This element also incorporates
an estimate of the loss emergence period, which is an estimate of the time between when a credit event occurs and
when the charge-off of a loan occurs. The process is an estimate and is, therefore, imprecise. For example, if our
estimate of the loss emergence period would have been increased/decreased by one quarter, it would have resulted in
an increase of $2.5 million and a decrease of $2.6 million, respectively, in our allowance at December 31, 2017.   

The qualitative adjustment is based on management's evaluation of conditions that are not directly reflected in the loss
migration analysis and/or specific reserve. The evaluation of the inherent loss with respect to these conditions is subject
to a higher degree of uncertainty because they may not be identified with specific problem credits. The conditions
evaluated in connection with the qualitative or environmental adjustment include the following:

•
•
•
•
•
•
•
•
•

changes in lending policies and procedures;
changes in business and economic conditions;
changes in the nature and volume of our loan portfolio;
changes in our lending department;
changes in volume and/or severity of past due loans;
changes in the quality of our loan review system;
changes in the value of underlying collateral related to loans;
existence and effect of concentrations of credit within our loan portfolio; and
other external factors such as asset quality trends (including trends in nonperforming loans expected to result
from existing conditions), and related allowance metrics of our peers.

Executive management reviews these conditions quarterly based on discussion with our lending staff. Management
then assigns a specified number of basis points of allowance to each factor above by loan category. To the extent that
any of these conditions is evidenced by a specifically identifiable problem credit or loan category as of the evaluation
date, management's estimate of the effect of such conditions may be reflected as a specific allowance, applicable to
such credit or loan category.  

The  allocation  of  the  allowance  for  loan  losses  by  loan  category  is  a  result  of  the  analysis  above. The  allocation
methodology applied by the Company focuses on changes in the size and character of the loan portfolio, changes in
levels of impaired and other nonperforming loans, the risk inherent in specific loans, concentrations of loans to specific
borrowers or industries, existing economic conditions, and historical losses on each portfolio category.  

Management believes the allowance for loan losses is adequate at December 31, 2017.

58

Purchased Credit Impaired ('PCI") Loans
PCI loans were acquired in a business combination or transaction that have evidence of deterioration of credit quality
since origination and for which it is probable, at acquisition, that the Company will be unable to collect all contractually
required payments receivable. PCI loans were initially recorded at fair value (as determined by the present value of
expected future cash flows) with no valuation allowance. The difference between the undiscounted cash flows expected
at acquisition and the investment in the loans, or the “accretable yield,” is recognized as interest income on a level-
yield method over the life of the loans. Contractually required payments for interest and principal that exceed the
undiscounted  cash  flows  expected  at  acquisition,  or  the  “nonaccretable  difference,”  are  not  recognized  as  a  yield
adjustment or as a loss accrual or a valuation allowance. The Company aggregates individual loans with common risk
characteristics into pools of loans. Increases in expected cash flows subsequent to the initial investment are recognized
prospectively through adjustment of the yield on the loans over their remaining lives. Decreases in expected cash flows
due to an inability to collect contractual cash flows are recognized as impairment through the provision for loan losses
account. Any allowance for loan loss on these pools reflect only losses incurred after the acquisition. Disposals of
loans, including sales of loans, paydowns, payments in full or foreclosures result in the removal or reduction of the
loan from the loan pool.

PCI loans are generally considered accruing and performing, as the loans accrete income over the estimated life of the
loan, in circumstances where cash flows are reasonably estimable by management. Accordingly, PCI loans that could
be contractually past due could be considered to be accruing and performing. If the timing and amount of future cash
flows is not reasonably estimable or is less than the carrying value, the loans may be classified as nonaccrual loans
and the purchase price discount on those loans is not recorded as interest income until the timing and amount of future
cash flows can be reasonably estimable.

Allowance for Loan Losses on PCI Loans
The Company updates its cash flow projections for purchased credit-impaired loans on a periodic basis. Assumptions
utilized in this process include projections related to probability of default, loss severity, prepayment, extensions and
recovery lag. Projections related to probability of default and prepayment are calculated utilizing a loan migration
analysis and management's assessment of loss exposure including the fair value of underlying collateral. The loan
migration analysis is a matrix that specifies the probability of a loan pool transitioning into a particular delinquency
or liquidation state given its current performance at the measurement date. Loss severity factors are based upon industry
data and historical experience. 

Any decreases in expected cash flows after the acquisition date and subsequent measurement periods are recognized
by recording an impairment in allowance for loan losses through a provision for loan losses.

Goodwill and Other Intangible Assets
The Company completes a goodwill impairment test in the fourth quarter each year or whenever events or changes in
circumstances indicate that the Company may not be able to recover the goodwill, or intangible assets, respective
carrying amount. The impairment test involves the use of various estimates and assumptions. Management believes
that the estimates and assumptions utilized are reasonable. However, the Company may incur impairment charges
related to goodwill or intangible assets in the future due to changes in business prospects or other matters that could
impact estimates and assumptions. 

Goodwill is evaluated for impairment at the reporting unit level. Reporting units are defined as the same level as, or
one level below, an operating segment. An operating segment is a component of a business for which separate financial
information  is  available  that  management  regularly  evaluates  in  deciding  how  to  allocate  resources  and  assess
performance. At December 31, 2017, the Company had one reporting unit and one operating segment.

Potential impairments to goodwill must first be identified by performing a qualitative assessment which evaluates
relevant events or circumstances to determine whether it is more likely than not that the fair value of a reporting unit
is less than its carrying amount. If this test indicates it is more likely than not that goodwill has been impaired, then a
quantitative impairment test is completed. The quantitative impairment test calculates the fair value of the reporting
unit and compares it with its carrying amount, including goodwill. If the carrying amount of goodwill exceeds its

59

implied fair market value, an impairment loss is recognized. That loss is equal to the carrying amount of goodwill that
is in excess of its implied fair market value.

Intangible assets other than goodwill, such as core deposit intangibles, that are determined to have finite lives are
amortized over their estimated remaining useful lives. These assets are reviewed for impairment whenever events or
changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets
to be held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted future
cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash
flows, an impairment charge is recognized by the amount by which the carrying amount of the asset exceeds the fair
value of the asset.

In 2017, we performed both a qualitative and quantitative assessment to determine if our goodwill was impaired. At
December 31, 2017 the Company had $117.3 million goodwill compared to $30.3 million at December 31, 2016 due
to the acquisition of JCB. The 2017 annual impairment evaluation of goodwill and intangible balances did not identify
any impairment.

Use of Non-GAAP Financial Measures
The Company's accounting and reporting policies conform to generally accepted accounting principles in the U.S.
("GAAP")  and  the  prevailing  practices  in  the  banking  industry.  However,  the  Company  provides  other  financial
measures, such as core net income and net interest margin, and other core performance measures, regulatory capital
ratios,  and  the  tangible  common  equity  ratio,  in  this  filing  that  are  considered  “non-GAAP  financial  measures.”
Generally, a non-GAAP financial measure is a numerical measure of a company's financial performance, financial
position, or cash flows that exclude (or include) amounts that are included in (or excluded from) the most directly
comparable measure calculated and presented in accordance with GAAP.

The Company considers its core performance measures as important measures of financial performance, even though
they are non-GAAP measures, as they provide supplemental information by which to evaluate the impact of non-core
acquired loans and related income and expenses, the impact of certain non-comparable items, and the Company's
operating  performance  on  an  ongoing  basis.  Core  performance  measures  include  contractual  interest  on  non-core
acquired  loans,  but  exclude  incremental  accretion  on  these  loans.  Core  performance  measures  also  exclude  the
following:
•
•
•

the change in the FDIC loss share receivable,
gain or loss on sale of other real estate from non-core acquired loans,
expenses directly related to non-core acquired loans and other assets formerly covered under FDIC loss share
agreements, and
certain other income and expense items the Company believes to be not indicative of or useful to measure the
Company's operating performance on an ongoing basis, such as:

•

executive separation costs,

◦
◦ merger related expenses,
◦
◦
◦

facilities charges,
deferred tax asset revaluation due to U.S. corporate income tax reform, and
the gain or loss on sale of investment securities.

The  Company  believes  that  the  tangible  common  equity  ratio  provides  useful  information  to  investors  about  the
Company's capital strength, even though it is considered to be a non-GAAP financial measure, and is not part of the
regulatory capital requirements to which the Company is subject.

The Company believes these non-GAAP measures and ratios, when taken together with the corresponding GAAP
measures and ratios, provide meaningful supplemental information regarding the Company's performance and capital
strength. The Company's management uses, and believes that investors benefit from referring to, these non-GAAP
measures and ratios in assessing the Company's operating results and related trends and when forecasting future periods.
However, these non-GAAP measures and ratios should be considered in addition to, and not as a substitute for or
preferable  to,  ratios  prepared  in  accordance  with  GAAP.  The  Company  has  provided  a  reconciliation  of,  where
applicable, the most comparable GAAP financial measures and ratios to the non-GAAP financial measures and ratios,
or a reconciliation of the non-GAAP calculation of the financial measure for the periods indicated.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the shareholders and Board of Directors of
Enterprise Financial Services Corp

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Enterprise Financial Services Corp and subsidiaries
(the  "Company")  as  of  December 31,  2017  and  2016,  and  the  related  consolidated  statements  of  operations,
comprehensive income, shareholders' equity, and cash flows for each of the three years in the period ended December 31,
2017 and the related notes (collectively referred to as the "financial statements"). In our opinion, the consolidated
financial statements present fairly, in all material respects, the financial position of the Company as of December 31,
2017 and 2016, and the results of its operations and its cash flows for each of the three years in the period ended
December 31, 2017 in conformity with accounting principles generally accepted in the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United
States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2017, based on criteria
established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations
of  the  Treadway  Commission  and  our  report  dated  February 23,  2018,  expressed  an  unqualified  opinion  on  the
Company's internal control over financial reporting.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company's management. Our responsibility is to
express an opinion on these consolidated financial statements based on our audits. We are a public accounting firm
registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be
independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules
and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement
whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement
of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such
procedures  included  examining,  on  a  test  basis,  evidence  supporting  the  amounts  and  disclosures  in  the  financial
statements.  Our  audits  also  included  assessing  the  accounting  principles  used  and  significant  estimates  made  by
management, as well as evaluating the overall presentation of the financial statements. We believe that our audits
provide a reasonable basis for our opinion.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the shareholders and Board of Directors of
Enterprise Financial Services Corp

Opinion on Internal Control over Financial Reporting

We have audited the internal control over financial reporting of Enterprise Financial Services Corp and subsidiaries
(the "Company") as of December 31, 2017, based on criteria established in Internal Control - Integrated Framework
(2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion,
the Company maintained, in all material respects, effective internal control over financial reporting as of December 31,
2017, based on the criteria established in Internal Control - Integrated Framework (2013) issued by COSO.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United
States) (PCAOB), the consolidated financial statements as of and for the year ended December 31, 2017 of the Company
and our report dated February 23, 2018 expressed an unqualified opinion on those consolidated financial statements.

Basis for Opinion

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

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

Definition and Limitations of Internal Control over Financial Reporting

A company's internal control over financial reporting is a process designed by, or under the supervision of, the company's
principal  executive  and  principal  financial  officers,  or  persons  performing  similar  functions,  and  effected  by  the
company's board of directors, management, and other personnel 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.

67

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

ENTERPRISE FINANCIAL SERVICES CORP AND SUBSIDIARIES

Notes to Consolidated Financial Statements

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The significant accounting policies used by the Company in the preparation of the consolidated financial statements
are summarized below.

Business and Consolidation
Enterprise Financial Services Corp and subsidiaries (the “Company” or “Enterprise”) is a financial holding company
that provides a full range of banking and wealth management services to individuals and corporate customers primarily
located in the St. Louis, Kansas City, and Phoenix metropolitan markets through its banking subsidiary, Enterprise
Bank  &  Trust  (the  “Bank”).  The  consolidated  financial  statements  include  the  accounts  of  the  Company,  and  its
subsidiaries, all of which are wholly owned. All intercompany accounts and transactions have been eliminated.

The Company is subject to competition from other financial and nonfinancial institutions providing financial services
in the markets served by the Company's subsidiary. Additionally, the Company and its banking subsidiary are subject
to the regulations of certain federal and state agencies and undergo periodic examinations by those regulatory agencies.
The Company has one operating segment.  

Use of Estimates
The consolidated financial statements of the Company have been prepared in conformity with U.S. generally accepted
accounting principles (“U.S. GAAP”). In preparing the consolidated financial statements, management is required to
make  estimates  and  assumptions,  which  significantly  affect  the  reported  amounts  in  the  consolidated  financial
statements. Such estimates include the valuation of loans, goodwill, intangible assets, indemnification assets, and other
long-lived assets, along with assumptions used in the calculation of income taxes, among others. These estimates and
assumptions  are  based  on  management's  best  estimates  and  judgment.  Management  evaluates  its  estimates  and
assumptions on an ongoing basis using experience and other factors, including the current economic environment,
which  management  believes  to  be  reasonable  under  the  circumstances.  Management  adjusts  such  estimates  and
assumptions  when  facts  and  circumstances  dictate.  Decreased  real  estate  values,  volatile  credit  markets,  and
unemployment have combined to increase the uncertainty inherent in such estimates and assumptions. As future events
and their effects cannot be determined with precision, actual results could differ significantly from these estimates.
Changes in those estimates resulting from continuing changes in the economic environment will be reflected in the
financial statements in future periods.  

Cash Flow Information
For purposes of reporting cash flows, the Company considers cash and due from banks, interest-bearing deposits and
federal funds sold that mature within 90 days of the balance sheet date to be cash and cash equivalents. At December 31,
2017 and 2016, approximately $17.5 million, and $18.2 million, respectively, of cash and due from banks represented
required reserves on deposits maintained by the Company in accordance with Federal Reserve Bank requirements.

Investments
The Company has classified all investments in debt securities as available for sale or held to maturity.

Securities classified as available for sale are carried at fair value. Unrealized holding gains and losses for available for
sale securities are excluded from earnings and reported as a net amount in a separate component of shareholders' equity
until  realized. All  previous  fair  value  adjustments  included  in  the  separate  component  of  shareholders'  equity  are
reversed upon sale.

Securities classified as held to maturity are carried at historical cost and adjusted for amortization of premiums and
accretion of discounts.

75

 
Declines in the fair value of securities below their cost deemed to be other-than-temporary are reflected in operations
as  realized  losses.  In  estimating  other-than-temporary  impairment  losses,  management  systematically  evaluates
investment  securities  for  other-than-temporary  declines  in  fair  value  on  a  quarterly  basis. This  analysis  requires
management to consider various factors, which include (1) the present value of the cash flows expected to be collected
compared to the amortized cost of the security, (2) duration and magnitude of the decline in value, (3) the financial
condition of the issuer or issuers, (4) structure of the security, and (5) the intent to sell the security or whether it's more
likely than not the Company would be required to sell the security before its anticipated recovery in market value.

Premiums and discounts are amortized or accreted over the expected lives of the respective securities as an adjustment
to yield using the interest method.  Dividend and interest income is recognized when earned. Realized gains and losses
are included in earnings and are derived using the specific identification method for determining the cost of securities
sold.

Loans Held for Sale
The  Company  provides  long-term  financing  of  one-to-four-family  residential  real  estate  by  originating  fixed  and
variable rate loans. Long-term fixed and variable rate loans are sold into the secondary market with limited recourse.
Upon receipt of an application for a real estate loan, the Company determines whether the loan will be sold into the
secondary market or retained in the Company's loan portfolio. The interest rates on the loans sold are locked with the
buyer and the Company bears no interest rate risk related to these loans. Mortgage loans held for sale are carried at
the lower of cost or fair value, which is determined on a specific identification method. The Company does not retain
servicing on any loans sold, nor did the Company have any capitalized mortgage servicing rights at December 31,
2017 or 2016. Gains on the sale of loans held for sale are reported net of direct origination fees and costs in the
Company's consolidated statements of operations.

Portfolio Loans
Loans are reported at the principal balance outstanding, net of unearned fees, costs, and premiums or discounts on
acquired loans. Loan origination fees, direct origination costs, and premiums or discounts resulting from acquired
loans are deferred and recognized over the lives of the related loans as a yield adjustment using the interest method. 

Interest income on loans is accrued to income based on the principal amount outstanding. The recognition of interest
income is discontinued when a loan becomes 90 days past due or a significant deterioration in the borrower's credit
has occurred which, in management's judgment, negatively impacts the collectibility of the loan. Unpaid interest on
such loans is reversed at the time the loan becomes uncollectible and subsequent interest payments received are applied
to principal if any doubt exists as to the collectibility of such principal; otherwise, such receipts are recorded as interest
income. Loans that have not been restructured are returned to accrual status when management believes full collectibility
of principal and interest is expected. Non-accrual loans that have been restructured will remain in a non-accrual status
until the borrower has made at least six months of consecutive contractual payments.

Purchased Credit Impaired ("PCI") Loans 
PCI loans were acquired in a business combination or transaction, that have evidence of deterioration of credit quality
since origination and for which it is probable, at acquisition, that the Company will be unable to collect all contractually
required payments receivable. PCI loans were initially recorded at fair value (as determined by the present value of
expected future cash flows) with no valuation allowance. The difference between the undiscounted cash flows expected
at acquisition and the investment in the loans, or the “accretable yield,” is recognized as interest income on a level-
yield method over the life of the loans. Contractually required payments for interest and principal that exceed the
undiscounted  cash  flows  expected  at  acquisition,  or  the  “nonaccretable  difference,”  are  not  recognized  as  a  yield
adjustment or as a loss accrual or a valuation allowance. The Company aggregates individual loans with common risk
characteristics into pools of loans. Increases in expected cash flows subsequent to the initial investment are recognized
prospectively through adjustment of the yield on the loans over their remaining lives. Decreases in expected cash flows
due to an inability to collect contractual cash flows are recognized as impairment through the provision for loan losses
account. Any allowance for loan loss on these pools reflect only losses incurred after the acquisition. Disposals of
loans, including sales of loans, paydowns, payments in full or foreclosures result in the removal or reduction of the
loan from the loan pool.

76

 
PCI loans are generally considered accruing and performing, as the loans accrete income over the estimated life of
the loan, in circumstances where cash flows are reasonably estimable by management. Accordingly, PCI loans that
could be contractually past due could be considered to be accruing and performing. If the timing and amount of
future cash flows is not reasonably estimable or is less than the carrying value, the loans may be classified as
nonaccrual loans and the purchase price discount on those loans is not recorded as interest income until the timing
and amount of future cash flows can be reasonably estimable.

Impaired Loans 
Loans are considered “impaired” when it becomes probable that the Company will be unable to collect all amounts
due according to the loan's contractual terms. Non-accrual loans, loans past due greater than 90 days and still accruing,
unless  adequately  secured  and  in  the  process  of  collection,  and  restructured  loans  qualify  as  “impaired  loans.”
Restructured loans involve the granting of a concession to a borrower experiencing financial difficulty involving the
modification of terms of the loan, such as changes in payment schedule or interest rate. 

When measuring impairment, the expected future cash flows of an impaired loan are discounted at the loan's effective
interest rate at origination. Alternatively, impairment can be measured by reference to an observable market price, if
one exists, or the fair value of the collateral for a collateral-dependent loan. Interest income on impaired loans is not
accrued but is recorded when cash is received and only if principal is considered to be fully collectible. Loans and
leases, which are deemed uncollectible, are charged off to the allowance for loan losses, while recoveries of amounts
previously charged off are credited to the allowance for loan losses. 

Impaired loans exclude PCI loans, as described above. Although, if the timing and amount of future cash flows is not
reasonably estimable, the loans may be classified as nonaccrual loans and the purchase price discount on those loans
is not recorded as interest income until the timing and amount of future cash flows can be reasonably estimated. See
Note 5 – Loans for more information on these loans.

Loans are generally placed on non-accrual status when contractually past due 90 days or more as to interest or principal
payments. Additionally, whenever management becomes aware of facts or circumstances that may adversely impact
the collectability of principal or interest on loans, it is management's practice to place such loans on non-accrual status
immediately,  rather  than  delaying  such  action  until  the  loans  become  90  days  past  due.  Previously  accrued  and
uncollected interest on such loans is reversed. Income is recorded only to the extent that a determination has been
made that the principal balance of the loan is collectable and the interest payments are subsequently received in cash,
or for a restructured loan, the borrower has made six consecutive contractual payments.  If collectability of the principal
is in doubt, payments received are applied to loan principal. 

Loans past due 90 days or more but still accruing interest are also generally included in nonperforming loans. Loans
past due 90 days or more but still accruing are classified as such where the underlying loans are both well secured (the
collateral value is sufficient to cover principal and accrued interest) and are in the process of collection. At December 31,
2017, we did not have any loans past due greater than 90 days and not included in nonperforming loans. 

Loan Charge-Offs
Loans are charged-off when the  primary and secondary sources of repayment (cash flow, collateral, guarantors, etc.)
are less than their carrying value. 

Allowance For Loan Losses
The allowance for loan losses is increased by provision charged to expense and is available to absorb charge-offs, net
of recoveries. Management utilizes a systematic, documented approach in determining the appropriate level of the
allowance  for  loan  losses.  The  level  of  the  allowance  reflects  management's  continuing  evaluation  of  industry
concentrations; specific credit risks; loan loss experience; current loan portfolio quality; present economic, political
and  regulatory  conditions;  and  probable  losses  inherent  in  the  current  loan  portfolio.  The  determination  of  the
appropriate level of the allowance for loan losses inherently involves a degree of subjectivity and requires that the
Company  make  significant  estimates  of  current  credit  risks  and  future  trends,  all  of  which  may  undergo  material
changes. Changes in economic conditions affecting borrowers, new information regarding existing loans, identification

77

of additional problem loans and other factors, both within and outside of our control, may require an increase in the
allowance for loan losses.

Management believes the allowance for loan losses is adequate to absorb inherent losses in the loan portfolio. While
management uses available information to recognize losses on loans, future additions to the allowance may be necessary
based on changes in economic conditions and other factors. In addition, various regulatory agencies, as an integral
part of the examination process, periodically review the Bank's loan portfolio. Such agencies may require additions
to the allowance for loan losses based on their judgments and interpretations of information available to them at the
time of their examinations.

Allowance for Loan Losses on PCI Loans
The Company updates its cash flow projections for PCI loans on a periodic basis. Assumptions utilized in this process
include projections related to probability of default, loss severity, prepayment, extensions and recovery lag. Projections
related to probability of default and prepayment are calculated utilizing a loan migration analysis and management's
assessment of loss exposure including the fair value of underlying collateral. The loan migration analysis is a matrix
that specifies the probability of a loan pool transitioning into a particular delinquency or liquidation state given its
current  performance  at  the  measurement  date.  Loss  severity  factors  are  based  upon  industry  data  and  historical
experience. 

Any decreases in expected cash flows after the acquisition date and subsequent measurement periods are recognized
by recording an impairment in allowance for loan losses. 

Other Real Estate 
Other real estate represents property acquired through foreclosure or deeded to the Company in lieu of foreclosure on
loans on which the borrowers have defaulted on the payment of principal or interest. Other real estate is recorded on
an individual asset basis at the lower of cost or fair value less estimated costs to sell. The fair value of other real estate
is based upon estimates of future cash flows, market value of similar assets, if available, or independent appraisals.
These estimates involve significant uncertainties and judgments. As a result, fair value estimates may not be realizable
in a current sale or settlement of the other real estate.  Subsequent reductions in fair value are expensed within noninterest
expense.

Gains and losses resulting from the sale of other real estate are credited or charged to current period earnings. Costs
of maintaining and operating other real estate are expensed as incurred, and expenditures to complete or improve other
real estate properties are capitalized if the expenditures are expected to be recovered upon ultimate sale of the property.

Fixed Assets
Buildings, leasehold improvements, furniture, fixtures, equipment, and capitalized software are stated at cost less
accumulated depreciation. All categories are computed using the straight-line method over their respective estimated
useful  lives.  Furniture,  fixtures  and  equipment  is  depreciated  over  three  to  ten  years,  buildings  and  leasehold
improvements over ten to forty years, and capitalized software over three years based upon estimated lives or lease
obligation periods.

State Tax Credits Held for Sale
The Company has purchased the rights to receive 10-year streams of state tax credits at agreed upon discount rates
and sells such tax credits to its clients and others. All state tax credits purchased prior to 2009 are accounted for at fair
value. All state tax credits purchased since 2009 are accounted for at cost. The Company elected not to account for the
state tax credits purchased since 2009 at fair value in order to limit the volatility of the fair value changes in the
Company's consolidated statements of operations.

Cash Surrender Value of Life Insurance
The Company has purchased bank-owned life insurance policies on certain bank officers. Bank-owned life insurance
is recorded at its cash surrender value. Changes in the cash surrender values are included in noninterest income.

78

Federal Home Loan Bank Stock
The Bank, as a member of the Federal Home Loan Bank of Des Moines (“FHLB”), is required to maintain an investment
in the capital stock of the FHLB. The stock is redeemable at par by the FHLB, and is, therefore, carried at cost and
periodically evaluated for impairment. The Company records FHLB dividends in interest income.

Goodwill and Other Intangible Assets
The Company tests goodwill for impairment on an annual basis and whenever events or changes in circumstances
indicate that the Company may not be able to recover the respective asset's carrying amount. The Company's annual
test for impairment was performed in the fourth quarter of December 31, 2017. Such tests involve the use of estimates
and assumptions. Core deposit intangibles are amortized using an accelerated method over an estimated useful life of
approximately 10 years.

Potential impairments to goodwill must first be identified by performing a qualitative assessment which evaluates
relevant events or circumstances to determine whether it is more likely than not that the fair value of a reporting unit
is less than its carrying amount. If this test indicates it is more likely than not that goodwill has been impaired, then a
quantitative impairment test is completed. The quantitative impairment test calculates the fair value of the reporting
unit and compares it with its carrying amount, including goodwill. If the carrying amount of goodwill exceeds its
implied fair market value, an impairment loss is recognized. That loss is equal to the carrying amount of goodwill that
is in excess of its implied fair market value.

Impairment of Long-Lived Assets
Long-lived assets, such as fixed assets and purchased intangibles subject to amortization, are reviewed for impairment
whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable.
Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated
undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its
estimated future cash flows, an impairment charge is recognized in the amount by which the carrying amount of the
asset exceeds the fair value of the asset. Assets to be disposed of are separately presented in the balance sheet and
reported at the lower of the carrying amount or fair value less costs to sell, and are no longer depreciated. The assets
and liabilities of a disposal group classified as held for sale are presented separately in the appropriate asset and liability
sections of the balance sheet.

Derivative Financial Instruments and Hedging Activities
The Company uses derivative financial instruments to assist in the management of interest rate sensitivity and to modify
the repricing, maturity and option characteristics of certain assets and liabilities. In addition, the Company also offers
an interest rate hedge program that includes interest rate swaps to assist its customers in managing their interest rate
risk profile. In order to eliminate the interest rate risk associated with offering these products, the Company enters into
derivative contracts with third parties to offset the customer contracts.  

Derivative instruments are required to be measured at fair value and recognized as either assets or liabilities in the
consolidated financial statements. Fair value represents the payment the Company would receive or pay if the item
were sold or bought in a current transaction. The accounting for changes in fair value (gains or losses) of a hedged
item is dependent on whether the related derivative is designated and qualifies for “hedge accounting.” The Company
assigns derivatives to one of these categories at the purchase date: cash flow hedge, fair value hedge, or non-designated
derivatives. An assessment of the expected and ongoing hedge effectiveness of any derivative designated a fair value
hedge or cash flow hedge is performed as required by the accounting standards. Derivatives are included in other assets
and other liabilities in the consolidated balance sheets. Generally, the only derivative instruments used by the Company
have been interest rate swaps and interest rate caps.   

The Company does not currently have derivative instruments designated as fair value or cash flow hedges. Certain
derivative financial instruments are not designated as cash flow or as fair value hedges for accounting purposes. These
non-designated derivatives are intended to provide interest rate protection on net interest income or noninterest income
but do not meet hedge accounting treatment. Customer accommodation interest rate swap contracts are not designated
as hedging instruments. Changes in the fair value of these instruments are recorded in interest income or noninterest
income in the consolidated statements of income depending on the underlying hedged item.

Income Taxes
The Company and its subsidiaries file a consolidated federal income tax return. Deferred tax assets and liabilities are
recognized for the estimated future tax consequences attributable to differences between the financial statement carrying
amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured
using enacted tax rates in effect for the year in which those temporary differences are expected to be recovered or
settled. We evaluated the need for deferred tax asset valuation allowances based on a more-likely-than-not standard.
The ability to realize deferred tax assets depends on the ability to generate sufficient positive taxable income within
the carryback or carryforward periods provided for in the laws for each applicable taxing jurisdiction. We consider the
following possible sources of taxable income: future reversal patterns of existing taxable temporary differences, future
taxable  income  exclusive  of  reversing  temporary  differences,  taxable  income  in  prior  carryback  years  and  the
availability of qualified tax planning strategies. The assessment regarding whether a valuation allowance is required
or  should  be  adjusted  depends  on  all  available  positive  and  negative  factors  including,  but  not  limited  to,  nature,
frequency, and severity of recent losses, duration of available carryforward periods, experience with tax attributes
expiring unused and near and medium term financial outlook. Because of the complexity of tax laws and regulations,
interpretation can be difficult and subject to legal judgment given specific facts and circumstances. It is possible that
others, given the same information, may at any point in time reach different reasonable conclusions regarding the
estimated amounts of accrued taxes.

The SEC staff issued SAB 118, which provides guidance on accounting for the tax effects of the Tax Cuts and Jobs
Act of 2017 (“Tax Act”).  SAB 118 provides a measurement period that should not extend beyond one year from the
Tax Act enactment date for companies to complete the accounting under ASC 740. In accordance with SAB 118, a
company must reflect the income tax effects of those aspects of the Act for which the accounting under ASC 740 is
complete. To the extent that a company’s accounting for certain income tax effects of the Tax Act is incomplete but it
is able to determine a reasonable estimate, it must record a provisional estimate in the financial statements. If a company
cannot determine a provisional estimate to be included in the financial statements, it should continue to apply ASC
740 on the basis of the provisions of the tax laws that were in effect immediately before the enactment of the Tax Act.
The Company has recorded amounts based on the information known and reasonable estimates used as of December
31, 2017, but are subject to change based on a number of factors.  The Company will complete its analysis of certain
tax positions at the time it files its tax returns for the year ended December 31, 2017 and will be able to conclude if
any further adjustments to the provisional estimate of the impact recorded is required. 

Stock-Based Compensation 
Stock-based compensation is recognized as an expense for stock options, restricted stock awards, and restricted stock
units granted to employees in return for employee service. Equity classified awards are measured at the grant date fair
value using either an observable market value or a valuation methodology, and recognized over the requisite service
period on a straight-line basis. Forfeitures are recorded as they occur. A description of the Company's stock-based
employee compensation plan is described in Note 15 - Compensation Plans. 

Acquisitions and Divestitures
Acquisitions and business combinations are accounted for using the acquisition method of accounting. The assets and
liabilities of the acquired entities have been recorded at their estimated fair values at the date of acquisition. Goodwill
represents the excess of the purchase price over the fair value of net assets acquired, including the amount assigned
to identifiable intangible assets.

The purchase price allocation process requires an estimation of the fair values of the assets acquired and the liabilities
assumed. When a business combination agreement provides for an adjustment to the cost of the combination contingent
on  future  events,  the  Company  includes  an  estimate  of  the  acquisition-date  fair  value  as  part  of  the  cost  of  the
combination. To determine the fair values, the Company relies on third party valuations, such as appraisals, or internal
valuations based on discounted cash flow analyses or other valuation techniques. The results of operations of the
acquired business are included in the Company's consolidated financial statements from the date of acquisition. Merger-
related  costs  are  costs  the  Company  incurs  to  effect  a business  combination.  In  2017,  the  Company  changed  its
presentation  of  Merger  related  expenses  as  a  separate  component  of  Noninterest  expenses  on  the  Condensed

80

Consolidated Statements of Operations.  Merger related expenses include costs directly related to merger or acquisition
activity and include legal and professional fees, system consolidation and conversion costs, and compensation costs
such as severance and retention incentives for employees impacted by acquisition activity. The Company accounts for
merger-related costs as expenses in the periods in which the costs are incurred and the services are received.

For divestitures, the Company measures an asset (disposal group) classified as held for sale at the lower of its carrying
value at the date the asset is initially classified as held for sale or its fair value less costs to sell. The Company reports
the  results  of  operations  of  an  entity  or  group  of  components  that  either  has  been  disposed  of  or  held  for  sale  as
discontinued operations only if the disposal of that component represents a strategic shift that has or will have a major
effect on an entity's operations and financial results.

Any incremental direct costs incurred to transact the sale are allocated against the gain or loss on the sale. These costs
would include items like legal fees, title transfer fees, broker fees, etc. Any goodwill and intangible assets associated
with the portion of the reporting unit to be disposed of is included in the carrying amount of the business in determining
the gain or loss on the sale.

Basic and Diluted Earnings Per Common Share
Basic earnings per common share data is calculated by dividing net income available to common shareholders by the
weighted  average  number  of  common  shares  outstanding  during  the  period.  Common  shares  outstanding  include
common stock and restricted stock awards where recipients have satisfied the vesting terms. Diluted earnings per
common share gives effect to all dilutive potential common shares outstanding during the period using the treasury
stock method. 

Consolidated Statement of Comprehensive Income
The Consolidated Statement of Comprehensive Income includes the amount and the related tax impact that have been
reclassified from accumulated other comprehensive income to net income. The classification adjustment for unrealized
loss/gain on sale of securities included in net income has been recorded through the gain on sale of investment securities
line item, within noninterest income, in the Company's Consolidated Statements of Operations.  

Reclassifications
Some items in the prior year financial statements were reclassified to conform to the current presentation. In 2017, the
Company changed its presentation of loans on the face of the Consolidated Balance Sheets to combine originated loans
with purchased loans. See Note 5 - Loans for more information. The Company also changed its presentation of the
Noninterest Income section on the face of the Consolidated Statements of Operations to separate card services revenue
from other service charges and fee income. The difference was reclassified into miscellaneous income. Merger related
expenses were reclassified from other expenses to be a separate component of the Noninterest Expense section on the
Consolidated Statements of Operations. Reclassifications had no effect on prior year net income or shareholders' equity.

NOTE 2 - ACQUISITIONS & DIVESTITURES

Acquisition of Jefferson County Bancshares, Inc.

On February 10, 2017, the Company closed its acquisition of 100% of Jefferson County Bancshares, Inc. ("JCB") and
its wholly-owned subsidiary, Eagle Bank and Trust Company of Missouri. JCB operated 13 full service retail and
commercial banking offices in the metropolitan St. Louis area and one in Perry County, Missouri.

JCB shareholders received, based on their election, cash consideration in an amount of $85.39 per share of JCB common
stock or 2.75 shares of EFSC common stock per share of JCB common stock, subject to allocation and proration
procedures. Aggregate consideration at closing was 3.3 million shares of EFSC common stock and $29.3 million cash
paid  to  JCB  shareholders  and  holders  of  JCB  stock  options.  Based  on  EFSC’s  closing  stock  price  of  $42.95  on
February 10, 2017, the overall transaction had a value of $171.0 million, including JCB’s common stock and stock
options. The Company also recognized $6.5 million and $1.4 million of merger related costs that were recorded in
noninterest expense in the statement of operations for the years ended December 31, 2017 and 2016, respectively.  

The acquisition of JCB has been accounted for as a business combination using the acquisition method of accounting
which requires assets acquired and liabilities assumed to be recognized at fair value as of the acquisition date. Goodwill
of $87.0 million arising from the acquisition consists largely of the synergies and economies of scale expected from
combining the operations of JCB into Enterprise. The goodwill is assigned as part of the Company's Banking reporting
unit.  None of the goodwill recognized is expected to be deductible for income tax purposes.

The following table provides the unaudited pro forma information for the results of operations for the twelve months
ended December 31, 2017 and 2016, as if the acquisition had occurred on January 1, 2016. The pro forma results
combine the historical results of JCB with the Company’s Consolidated Statements of Income, adjusted for the impact
of  the  application  of  the  acquisition  method  of  accounting  including  loan  discount  accretion,  intangible  assets
amortization, and deposit and trust preferred securities premium accretion, net of taxes. The pro forma results have
been prepared for comparative purposes only and are not necessarily indicative of the results that would have been
obtained had the acquisition actually occurred on January 1, 2016. No assumptions have been applied to the pro forma
results of operations regarding possible revenue enhancements, expense efficiencies or asset dispositions. Only the
acquisition related expenses that have been incurred as of December 31, 2017 are included in net income in the table

At December 31, 2017, and 2016, there were no holdings of securities of any one issuer in an amount greater than
10% of shareholders’ equity, other than the U.S. Government agencies and sponsored enterprises.  The agency mortgage-
backed securities are all issued by U.S. Government-sponsored enterprises. Securities having a fair value of $500.0
million and $407.3 million at December 31, 2017, and December 31, 2016, respectively, were pledged as collateral to
secure deposits of public institutions and for other purposes as required by law or contract provisions.

The unrealized losses at both December 31, 2017, and 2016, were primarily attributable to changes in market interest
rates since the securities were purchased. Management systematically evaluates investment securities for other-than-
temporary declines in fair value on a quarterly basis. This analysis requires management to consider various factors,
which include among other considerations (1) the present value of the cash flows expected to be collected compared
to the amortized cost of the security, (2) duration and magnitude of the decline in value, (3) the financial condition of
the issuer or issuers, (4) structure of the security, and (5) the intent to sell the security or whether it is more likely than
not  that  the  Company  would  be  required  to  sell  the  security  before  its  anticipated  recovery  in  market  value. At
December 31, 2017 and 2016, management performed its quarterly analysis of all securities with an unrealized loss
and concluded no individual securities were other-than-temporarily impaired.

Other Investments, At Cost
At December 31, 2017, and 2016, other investments, at cost, totaled $26.7 million, and $14.8 million, respectively.
As a member of the FHLB system administered by the Federal Housing Finance Agency, the Bank is required to
maintain a minimum investment in capital stock with the FHLB Des Moines consisting of membership stock and
activity-based stock. The FHLB capital stock of $12.9 million, and $4.4 million at December 31, 2017, and 2016,
respectively,  is  recorded  at  cost,  which  represents  redemption  value,  and  is  included  in  other  investments  in  the
consolidated balance sheets. The remaining amounts in other investments include various investments in SBICs and
the Company's investment in unconsolidated trusts used to issue preferred securities to third parties (see Note 10 –

The Company categorizes loans into risk categories based on relevant information about the ability of borrowers to
service their debt, such as current financial information, historical payment experience, credit documentation, and
current economic factors among other factors. This analysis is performed on a quarterly basis. The Company uses the
following definitions for risk ratings:

• Grades 1, 2, and 3 – Includes loans to borrowers with a continuous record of strong earnings, sound balance
sheet condition and capitalization, ample liquidity with solid cash flow, and whose management team has
experience and depth within their industry.

• Grade 4 – Includes loans to borrowers with positive trends in profitability, satisfactory capitalization and

balance sheet condition, and sufficient liquidity and cash flow.

• Grade 5 – Includes loans to borrowers that may display fluctuating trends in sales, profitability, capitalization,

liquidity, and cash flow.

92

• Grade 6 – Includes loans to borrowers where an adverse change or perceived weakness has occurred, but may
be correctable in the near future. Alternatively, this rating category may also include circumstances where the
borrower is starting to reverse a negative trend or condition, or has recently been upgraded from a 7, 8, or 9
rating.

• Grade 7 – Watch credits are borrowers that have experienced financial setback of a nature that is not determined
to be severe or influence ‘ongoing concern’ expectations.  Although possible, no loss is anticipated, due to
strong collateral and/or guarantor support.

• Grade 8 – Substandard credits will include those borrowers characterized by significant losses and sustained
downward trends in balance sheet condition, liquidity, and cash flow. Repayment reliance may have shifted
to secondary sources. Collateral exposure may exist and additional reserves may be warranted.

• Grade  9  –  Doubtful  credits  include  borrowers  that  may  show  deteriorating  trends  that  are  unlikely  to  be
corrected. Collateral values may appear insufficient for full recovery, therefore requiring a partial charge-off,
or debt renegotiation with the borrower. The borrower may have declared bankruptcy or bankruptcy is likely
in the near term. All doubtful rated credits will be on non-accrual.

The accretable yield is recognized in interest income over the estimated life of the acquired loans using the effective
yield method.

Outstanding customer balances on PCI loans were $94.9 million and $54.6 million as of December 31, 2017, and
December 31, 2016, respectively. 

On December 7, 2015, the Company entered into an agreement to terminate all existing loss share agreements with
the FDIC. Under the terms of the agreement, the FDIC made a net payment to the bank of $1.3 million. The agreement
eliminated the FDIC clawback liability of $3.5 million and the FDIC loss share receivable of $7.2 million. Accordingly,
a pretax charge of $2.4 million was recorded in 2015 as a separate component of noninterest expense.

NOTE 6 - DERIVATIVE FINANCIAL INSTRUMENTS

The Company is a party to various derivative financial instruments that are used in the normal course of business to
meet the needs of its clients and as part of its risk management activities. These instruments include interest rate swaps
and option contracts and foreign exchange forward contracts. The Company does not enter into derivative financial
instruments for trading purposes.

Using derivative instruments can involve assuming counterparty credit risk to varying degrees. Counterparty credit
risk relates to the loss the Company could incur if a counterparty were to default on a derivative contract. Notional
amounts of derivative financial instruments do not represent credit risk, and are not recorded in the consolidated balance
sheet. The overall credit risk and exposure to individual counterparties is monitored. The Company does not anticipate
nonperformance by any counterparties. The amount of counterparty credit exposure is the unrealized gains in excess
of collateral pledged, if any, on such derivative contracts along with the value of foreign exchange forward contracts.
At December 31, 2017, the Company had $2.1 million of counterparty credit exposure on derivatives. This counterparty
risk is considered as part of underwriting and on-going monitoring policies. At December 31, 2017 and 2016, the
Company had pledged cash of $1.4 million and $0.7 million, respectively, as collateral in connection with interest rate
swap agreements.

Hedging Instruments. At December 31, 2017, the Company had no outstanding hedging instruments used to manage
risk. In the past, the Company entered into interest rate caps in order to economically hedge changes in fair value of
certain state tax credits held for sale. See Note 18 – Fair Value Measurements for further discussion of the fair value
of the state tax credits. The notional amount of the derivative instruments used to manage risk was $3.5 million at
December 31, 2016.

Client-Related Derivative Instruments. The Company enters into interest rate swaps to allow customers to hedge
changes in fair value of certain loans while maintaining a variable rate loan on its balance sheet. The Company also
enters into foreign exchange forward contracts with clients, and enters into offsetting foreign exchange forward contracts
with established financial institution counterparties. The table below summarizes the notional amounts and fair values
of the client-related derivative instruments.

(1) Purchase accounting adjustments are reflected in the balance and also impact the effective interest rate.

The Company has 10 unconsolidated statutory business trusts. These trusts issued preferred securities that were sold
to third parties. The sole purpose of the trusts was to invest the proceeds in junior subordinated debentures of the
Company that have terms identical to the trust preferred securities. The subordinated debentures, which are the sole
assets of the trusts, are subordinate and junior in right of payment to all present and future senior and subordinated
indebtedness and certain other financial conditions of the Company. The Company fully and unconditionally guarantees
each trust's securities obligations. Under current regulations, the trust preferred securities are included in tier 1 capital
for regulatory capital purposes, subject to certain limitations.

The trust preferred securities are redeemable in whole or in part on or after their respective call dates. Mandatory
redemption dates may be shortened if certain conditions are met. The securities are classified as subordinated debentures
in the Company's consolidated balance sheets. Interest on the subordinated debentures held by the trusts is recorded
as interest expense in the Company's consolidated statements of operations. The Company's investment of $2.1 million
at December 31, 2017, in these trusts is included in other investments in the consolidated balance sheets.

On November 1, 2016, the Company issued $50 million of fixed-to-floating rate subordinated notes. The notes initially
bear a fixed annual interest rate of 4.75%, with interest payable semiannually in arrears on May 1 and November 1 of
each year, commencing May 1, 2017. Commencing November 1, 2021, the interest rate on the notes resets quarterly
to the three-month LIBOR rate plus a spread of 338.7 basis points, payable quarterly in arrears. On or after November
1, 2021, the Company will have the option to redeem the notes, in whole or in part, at a redemption price equal to
100% of the principal amount of the subordinated notes to be redeemed plus accrued interest, subject to applicable
regulatory approval. The Company’s obligation to make payments of principal and interest on the notes is subordinate
and junior in right of payment to all of its senior debt. Current regulatory guidance allows for this subordinated debt
to be treated as tier 2 regulatory capital for the first five years of its term, subject to certain limitations, and then phased
out of tier 2 capital pro rata over the next five years.

NOTE 14 - REGULATORY MATTERS

Quantitative measures established by regulation to ensure capital adequacy require the Bank to maintain minimum
amounts and ratios (set forth in the following table) of total, tier 1, and common equity tier 1 capital to risk-weighted
assets,  and  of  tier 1  capital  to  average  assets.  Management  believes,  as  of  December 31,  2017  and  2016,  that  the
Company met all capital adequacy requirements to which it is subject.

As of December 31, 2017 and 2016, the Bank was categorized as “well capitalized” under the regulatory framework
for prompt corrective action. To be categorized as “well capitalized” the Bank must maintain minimum total risk-based
capital, tier 1 risk-based capital, common equity tier 1 risk-based capital, and tier 1 leverage ratios as set forth in the
table.

NOTE 15 - COMPENSATION PLANS

The Company has adopted share-based compensation plans to reward and provide long-term incentive for directors
and key employees of the Company. These plans provide for the granting of stock, stock options, stock-settled stock
appreciation rights ("SSARs"), and restricted stock units (“RSUs”), and may contain performance terms as designated
by the Company's Board of Directors upon the recommendation of the Compensation Committee of the Board. The
Company uses authorized and unissued shares to satisfy share award exercises. At December 31, 2017, there were
86,082 shares available for grant under the various share-based compensation plans.

Total share-based compensation expense that was charged against income was $3.4 million, $3.4 million, and $3.6
million for the years ended December 31, 2017, 2016, and 2015 respectively. The total excess income tax benefit for
share-based  compensation  arrangements  was  $2.1  million,  $1.3  million,  and  $0.4  million  for  the  years  ended
December 31, 2017, 2016, and 2015, respectively.

Employee Stock Options and Stock-settled Stock Appreciation Rights
In determining compensation cost for stock options and SSARs, the Black-Scholes option-pricing model is used to
estimate the fair value on date of grant. There were no grants of employee stock options or SSARs during the years
ended December 31, 2017, 2016, or 2015.

Stock options have been granted to key employees with exercise prices equal to the market price of the Company's
common stock at the date of grant and 10-year contractual terms. Stock options have a vesting schedule of three to
five years. The SSARs are subject to continued employment, have a 10-year contractual term and vest ratably over
five years. Neither stock options nor SSARs carry voting or dividend rights until exercised. At December 31, 2017,
there was no remaining unrecognized compensation expense related to stock options and SSARs and all outstanding
awards are vested. Various information related to the stock options and SSARs is shown below.

Restricted Stock Units
The Company awards nonvested stock, in the form of RSUs to employees and directors. RSUs generally are subject
to continued employment and vest ratably over two to five years. Vesting is accelerated upon a change in control or
the employee meeting certain retirement criteria. RSUs do not carry voting or dividend rights until vested. Sales of
the units are restricted prior to vesting. Various information related to the RSUs is shown below.

Employee Stock Issuance
Restricted stock was issued to certain key employees as part of their compensation. The restricted stock may be in the
form of a one-time award or paid in pro rata installments. The stock is restricted for at least 2 years and upon issuance
may be fully vested or vest over 5 years. The Company recognized $0.1 million, zero, and $0.2 million of stock-based
compensation expense for the shares issued to the employees in 2017, 2016, and 2015, respectively. The Company
issued zero shares in 2017 and 2016, and 14,110 shares in 2015. 

Long-term incentives
The  Company  has  entered  into  long-term  incentive  agreements  with  certain  key  employees.  These  awards  are
conditioned on certain performance criteria and market criteria measured against a group of peer banks over a 3 year
period for each grant. The awards contain minimum (threshold), target, and maximum (exceptional) performance
levels. In the event of a change in control, as defined in the plan, the awards will vest at a minimum of the target level.
The amount of the awards are determined at the end of the 3 year vesting and performance period. In January 2018,
the Company awarded 134,600 shares to employees upon completion of the 2015-2017 performance cycle. In February

The Company recorded $2.5 million, $2.5 million and $2.7 million of stock-based compensation expense for these
awards during 2017, 2016 and 2015, respectively. In 2017 and 2016, this expense included an additional $0.3 million,
and  $0.2  million,  respectively,  related  to  modifications  made  for  retiring  executives. The  modification  allows  for
portions of outstanding performance awards to continue to vest as though employment had not terminated and will be
paid based on actual performance as determined by the compensation committee following completion of the applicable
performance period.

401(k) plans
The Company has a 401(k) savings plan which covers substantially all full-time employees over the age of 21. The
amount charged to expense for the Company's contributions to the plan was $2.0 million, $1.7 million and $1.6 million
for 2017, 2016, and 2015, respectively.

The net amount recognized as a component of tax expense for tax credits, other tax benefits, and amortization from
low-income housing tax credit ("LIHTC") investments recognized per the table above was $0.3 million for the year
ended December 31, 2017. The net amount recognized as a component of income tax expense per the table above was
$0.2 million for the years ended December 31, 2016, and 2015. As of December 31, 2017 and 2016, the carrying value
of  the  investments  related  to  low-income  housing  tax  credits  was  $1.3  million  and  $1.4  million,  respectively.  No
impairment losses have been recognized from forfeiture or ineligibility of tax credits or other circumstances during
the life of any of the investments. As of December 31, 2017, the Company has future capital commitments of $4.8
million related to low-income housing tax credit investments. The capital commitments are expected to be called
between the years 2018 - 2020.

Net  deferred  tax  assets  for  the  year  ended  December  31,  2017,  experienced  an  increase  of  $8.6  million  from  the
acquisition of JCB, offset by a revaluation adjustment of $12.1 million due to our initial analysis of the impact of the
Tax Act.

A valuation allowance is provided on deferred tax assets when it is more likely than not that some portion of the assets
will not be realized. The Company did not have any valuation allowances for federal or state income taxes as of
December 31, 2017 or 2016. 

The Company and its subsidiaries file income tax returns in the federal jurisdiction and in nine states. The Company
is  no  longer  subject  to  federal,  state  or  local  income  tax  audits  by  tax  authorities  for  years  before  2014,  with  the
exception of 2013 being an open year by one state taxing authority. The Company is not currently under audit by any
taxing jurisdiction.

As of December 31, 2017, the gross amount of unrecognized tax benefits was $1.2 million and the total amount of net
unrecognized tax benefits that would impact the effective tax rate, if recognized, was $0.8 million. As of December 31,
2016  and  2015,  the  total  amount  of  the  net  unrecognized  tax  benefits  that  would  impact  the  effective  tax  rate,  if
recognized, was $0.8 million and $0.9 million, respectively. The Company believes it is reasonably possible that the
gross amount of unrecognized benefits will be reduced by approximately $0.3 million as a result of a lapse of statute
of limitations in the next 12 months.

The Company recognizes interest and penalties related to uncertain tax positions in income tax expense and classifies
such interest and penalties in the liability for unrecognized tax benefits. The amounts accrued for interest and penalties
as of December 31, 2017, 2016, and 2015 were not significant.

NOTE 17 - COMMITMENTS

The Company issues financial instruments in the normal course of the business of meeting the financing needs of its
customers. These financial instruments include commitments to extend credit and standby letters of credit. These
instruments may involve, to varying degrees, elements of credit and interest rate risk in excess of the amounts recognized
in the consolidated balance sheets.

The Company’s extent of involvement and maximum potential exposure to credit 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 not more
than the contractual amount of these instruments.

The Company uses the same credit policies in making commitments and conditional obligations as it does for financial
instruments included on its consolidated balance sheets. 

The contractual amounts of off-balance-sheet financial instruments as of December 31, 2017, and December 31, 2016,
are as follows:

Commitments to extend credit

$

1,298,423

$

73,790

1,075,170

78,954

There  was  an  insignificant  amount  of  unadvanced  commitments  on  impaired  loans  at  December 31,  2017  and
December 31,  2016.  Other  liabilities  include  approximately  $0.4  million  for  estimated  losses  attributable  to  the
unadvanced commitments. 

Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition
established in the contract. Commitments usually have fixed expiration dates or other termination clauses, may have
significant  usage  restrictions,  and  may  require  payment  of  a  fee.  Of  the  total  commitments  to  extend  credit  at
December 31, 2017, and December 31, 2016, $112.0 million and $89.7 million, respectively, represent fixed rate loan
commitments. Since certain of the commitments may expire without being drawn upon or may be revoked, the total
commitment amounts do not necessarily represent future cash obligations. The Company evaluates each customer’s
credit worthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Company
upon extension of credit, is based on management’s credit evaluation of the borrower. Collateral held varies, but may
include accounts receivable, inventory, premises and equipment, and real estate.

Letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to
a third party. These letters of credit are issued to support contractual obligations of the Company’s customers. The
credit risk involved in issuing letters of credit is essentially the same as the risk involved in extending loans to customers.
The approximate remaining term of letters of credit range from 1 month to 3 years and 9 months at December 31,
2017.

NOTE 18 - FAIR VALUE MEASUREMENTS

The fair value of an asset or liability is the price that would be received to sell that asset or paid to transfer that liability
in an orderly transaction occurring in the principal market (or most advantageous market in the absence of a principal
market) for such asset or liability. In estimating fair value, the Company utilizes valuation techniques that are consistent
with the market approach, the income approach and/or the cost approach. Such valuation techniques are consistently
applied. Inputs to valuation techniques include the assumptions that market participants would use in pricing an asset
or liability. ASC Topic 820, Fair Value Measurements and Disclosures, establishes a fair value hierarchy for valuation
inputs that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest
priority to unobservable inputs. The fair value hierarchy is as follows: 

•

•

•

Level 1 Inputs - Unadjusted quoted prices in active markets for identical assets or liabilities that the reporting entity
has the ability to access at the measurement date.

Level 2 Inputs - Inputs other than quoted prices included in Level 1 that are observable for the asset or liability,
either directly or indirectly. These might include quoted prices for similar assets or liabilities in active markets,
quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted
prices that are observable for the asset or liability (such as interest rates, volatilities, prepayment speeds, credit
risks, etc.) or inputs that are derived principally from or corroborated by market data by correlation or other means.

Level 3 Inputs - Unobservable inputs for determining the fair values of assets or liabilities that reflect an entity's
own assumptions about the assumptions that market participants would use in pricing the assets or liabilities.

Fair value on a recurring basis

Securities available for sale. Securities classified as available for sale are reported at fair value utilizing Level
2 and Level 3 inputs. Fair values for Level 2 securities are based upon dealer quotes, market spreads, the U.S.
Treasury yield curve, trade execution data, market consensus prepayment speeds, credit information and the
bond's terms and conditions at the security level. At December 31, 2017, there were no Level 3 Auction Rate
Securities. Auction Rate Securities at December 31, 2017 were valued using a Level 2 pricing source similar
to our other securities available for sale.

State tax credits held for sale. At December 31, 2017, of the $43.5 million of state tax credits held for sale on
the consolidated balance sheet, approximately $0.4 million were carried at fair value. The remaining $43.1
million of state tax credits were accounted for at cost. The Company elected not to account for the state tax
credits  purchased  since  2010  at  fair  value  in  order  to  limit  the  volatility  of  the  fair  value  changes  in  our
consolidated statements of operations.

The Company is not aware of an active market that exists for the 10-year streams of state tax credit financial
instruments. However, the Company’s principal market for these tax credits consists of Missouri state residents
who  buy  these  credits  and  local  and  regional  accounting  firms  who  broker  them. As  such,  the  Company
employed a discounted cash flow analysis (income approach) to determine the fair value.

The  fair  value  measurement  is  calculated  using  an  internal  valuation  model  with  market  data  including
discounted cash flows based upon the terms and conditions of the tax credits. If the underlying project remains
in compliance with the various federal and state rules governing the tax credit program, each project will
generate about 10 years of tax credits. The inputs to the discounted cash flow calculation include: the amount
of tax credits generated each year, the anticipated sale price of the tax credit, the timing of the sale and a
discount rate. The discount rate is estimated using the LIBOR swap curve at a point equal to the remaining
life in years of credits plus a 205 basis point spread. With the exception of the discount rate, the other inputs
to the fair value calculation are observable and readily available. The discount rate is considered a Level 3
input because it is an “unobservable input” and is based on the Company’s assumptions. An increase in the
discount rate utilized would generally result in a lower estimated fair value of the tax credits. Alternatively, a
decrease in the discount rate utilized would generally result in a higher estimated fair value of the tax credits.
Given the significance of this input to the fair value calculation, the state tax credit assets are reported as Level
3 assets.

110

• Derivatives. Derivatives are reported at fair value utilizing Level 2 inputs. The Company obtains counterparty
quotations  to  value  its  interest  rate  swaps  and  caps.  In  addition,  the  Company  validates  the  counterparty
quotations  with  third  party  valuation  sources.  Derivatives  with  negative  fair  values  are  included  in  Other
liabilities in the consolidated balance sheets. Derivatives with positive fair value are included in Other assets
in the consolidated balance sheets.

as of December 31, 2017 and 2016.

Transfers in and/or out of Level 3. There was $3.1 million in Level 3 transfers to Level 2 for the year ending
December 31, 2017 because more observable market data became available for the Auction Rate Securities.
The Company's policy is to recognize transfers into or out of a level as of the end of a reporting period. As a
result, the transfers occurred on June 30, 2017. There were no transfers in and/or out of Level 3 for the year
ending 2016.

Fair value on a non-recurring basis
Certain financial assets and financial liabilities are measured at fair value on a non-recurring basis; that is, the instruments
are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances
(for example, when there is evidence of impairment). 

•

Impaired loans.  Impaired loans are included as Portfolio loans on the Company's consolidated balance sheets with
amounts specifically reserved for credit impairment in the Allowance for loan losses. On a quarterly basis, fair
value adjustments are recorded on impaired loans to account for (1) partial write-downs that are based on the
current appraised or market-quoted value of the underlying collateral or (2) the full charge-off of the loan carrying
value. In some cases, the properties for which market quotes or appraised values have been obtained are located
in areas where comparable sales data is limited, outdated, or unavailable. In addition, the Company may adjust
the valuations based on other relevant market conditions or information. Accordingly, fair value estimates, including
those obtained from real estate brokers or other third-party consultants, for collateral-dependent impaired loans
are classified in Level 3 of the valuation hierarchy. 

• Other Real Estate.  These assets are reported at the lower of the loan carrying amount at foreclosure or fair value.
Fair value is based on third party appraisals of each property and the Company's judgment of other relevant market
conditions. These are considered Level 3 inputs. 

The following table presents financial instruments and non-financial assets measured at fair value on a non-recurring

Impaired loans are reported at the fair value of the underlying collateral. Fair values for impaired loans are obtained
from current appraisals by qualified licensed appraisers or independent valuation specialists. Other real estate owned
is adjusted to fair value upon foreclosure of the underlying loan. Subsequently, foreclosed assets are carried at the
lower of carrying value or fair value less costs to sell. Fair value of other real estate is based upon the current appraised
values of the properties as determined by qualified licensed appraisers and the Company’s judgment of other relevant
market conditions. Certain state tax credits are reported at cost.

The following methods and assumptions were used to estimate the fair value of each class of financial instruments for
which it is practical to estimate such value:

Cash, Federal funds sold, and other short-term instruments
For  cash  and  due  from  banks,  federal  funds  purchased,  interest-bearing  deposits,  and  accrued  interest  receivable
(payable), the carrying amount is a reasonable estimate of fair value, as such instruments reprice in a short time period
(Level 1).

Securities available for sale and held to maturity
The Company obtains fair value measurements for debt instruments from an independent pricing service. The fair
value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S.
Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information
and the bond's terms and conditions (Level 2).

Other investments
Other investments, which primarily consists of membership stock in the FHLB, is reported at cost, which approximates
fair value (Level 2).

Loans held for sale
These loans consist of mortgages that are sold on the secondary market generally within three months of origination.
They are reported at cost, which approximates fair value (Level 2).

114

 
Portfolio loans, net 
The fair value of adjustable-rate loans approximates cost. The fair value of fixed-rate loans is estimated by discounting
the future cash flows using the current rates at which similar loans would be made to borrowers for the same remaining
maturities. The fair value of the acquired loans are based on the present value of expected future cash flows (Level 3).
The method of estimating fair value does not incorporate the exit-price concept of fair value prescribed by ASC Topic
820.

State tax credits held for sale
The fair value of state tax credits held for sale is calculated using an internal valuation model with unobservable market
data as discussed in further detail above (Level 3).

Derivative financial instruments
The fair value of derivative financial instruments is based on quoted market prices by the counterparty and verified
by the Company using public pricing information (Level 2).

Deposits
The fair value of demand deposits, interest-bearing transaction accounts, money market accounts and savings deposits
is the amount payable on demand at the reporting date (Level 1). The fair value of fixed-maturity certificates of deposit
is estimated by discounting the future cash flows using the rates currently offered for deposits of similar remaining
maturities (Level 3).  

Subordinated debentures and notes
Fair value of subordinated debentures and notes is based on discounting the future cash flows using rates currently
offered for financial instruments of similar remaining maturities (Level 2).

Federal Home Loan Bank advances
The fair value of the FHLB advances is based on the discounted value of contractual cash flows. The discount rate is
estimated using current rates on borrowed money with similar remaining maturities (Level 2).

Other borrowed funds
Other borrowed funds include customer repurchase agreements, federal funds purchased, notes payable, and secured
borrowings related to loan participations. The fair value of federal funds purchased, customer repurchase agreements
and notes payable are assumed to be equal to their carrying amount since they have an adjustable interest rate (Level
2).  

Commitments to extend credit and letters of credit
The fair value of commitments to extend credit and letters of credit are estimated using the fees currently charged to
enter  into  similar  agreements,  taking  into  account  the  remaining  terms  of  the  agreements,  the  likelihood  of  the
counterparties drawing on such financial instruments, and the present creditworthiness of such counterparties (Level
2). The Company believes such commitments have been made on terms which are competitive in the markets in which
it operates; however, no premium or discount is offered thereon and accordingly, the Company has not assigned a
value to such instruments for purposes of this disclosure.

Limitations
Fair value estimates are made at a specific point in time, based on relevant market information and information about
the financial instrument. These estimates are subjective in nature and involve uncertainties and matters of significant
judgment, and therefore, cannot be determined with precision. Such estimates include the valuation of loans, goodwill,
intangible assets, and other long-lived assets, along with assumptions used in the calculation of income taxes, among
others.  These  estimates  and  assumptions  are  based  on  management's  best  estimates  and  judgment.  Management
evaluates its estimates and assumptions on an ongoing basis using experience and other factors, including the current
economic environment, which management believes to be reasonable under the circumstances. We adjust such estimates
and assumptions when facts and circumstances dictate. Decreasing real estate values, illiquid credit markets, volatile
equity markets, and declines in consumer spending have combined to increase the uncertainty inherent in such estimates
and assumptions. As future events and their effects cannot be determined with precision, actual results could differ

115

significantly from these estimates. Changes in estimates resulting from continuing changes in the economic environment
will be reflected in the financial statement in future periods. In addition, these estimates do not reflect any premium
or discount that could result from offering for sale at one time the Company's entire holdings of a particular financial
instrument. Fair value estimates are based on existing on-balance and off-balance-sheet financial instruments without
attempting  to  estimate  the  value  of  anticipated  future  business  and  the  value  of  assets  and  liabilities  that  are  not
considered financial instruments. In addition, the tax ramifications related to the realization of the unrealized gains
and losses can have a significant effect on fair value estimates and have not been considered in many of the estimates.

NOTE 21 - NEW AUTHORITATIVE ACCOUNTING GUIDANCE

Financial Accounting Standards Board (the "FASB") Accounting Standards Update (the "ASU") 2018-02 "Income
Statement  -  Reporting  Comprehensive  Income  (Topic  220):  Reclassification  of  Certain  Tax  Effects  from
Accumulated Other Comprehensive Income" In February 2018, the FASB issued ASU 2018-02, "Reclassification
of Certain Tax Effects from Accumulated Other Comprehensive Income". The amendment allow a reclassification
from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax
Cuts and Jobs Act. Entities will be able to early adopt the guidance in any interim or annual period for which financial
statements have not yet been issued and apply it either (1) in the period of adoption or (2) retrospectively to each period
in which the effect of the change in the federal income tax rate in the Tax Cuts and Jobs Act is recognized. It would
also allow entities to elect to reclassify other stranded tax effects that relate to the Act but do not directly relate to the
change in the federal rate (e.g., state taxes, changing from a worldwide tax system to a territorial system). Tax effects
that are stranded in OCI for other reasons (e.g., prior changes in tax law, a change in valuation allowance) may not be
reclassified. The Company plans to adopt this standard in the first quarter of 2018, and apply it to the same period.
The adoption of this update will result in an increase to retained earnings of $0.8 million being reclassified from
accumulated other comprehensive income.

FASB ASU 2017-12 "Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging
Activities"  In August  2017,  the  FASB  issued ASU  2017-12,  "Targeted  Improvement  to Accounting  for  Hedging
Activities". The objective of ASU 2017-12 is to improve the financial reporting of hedging relationships by better
aligning an entity's risk management activity with the economic objectives in undertaking those activities. In addition,
the amendments in this update simplify the application of hedge accounting for preparers of financial statements, as
well as improve the understandability of an entity's risk management activities being conveyed to financial statement
users. The new guidance becomes effective for periods beginning after December 15, 2018, with early adoption being
permitted. The Company elected early adoption of this standard as of January 1, 2018. The effect of this adoption will
have a minimal impact on the Company's consolidated financial statements.

FASB ASU 2017-09 "Compensation - Stock Compensation (Topic 718): Scope of  Modification Accounting" In
May 2017, the FASB issued ASU 2017-09, "Compensation - Stock Compensation (Topic 718): Scope of Modification
Accounting" which amends the scope of modification accounting for share-based payment awards. The amendments
provide guidance on the types of changes to the terms or conditions of share-based payment awards to which an entity
would be required to apply modification accounting with an intent to simplify the accounting under ASC 718. The
amendments are effective for public business entities for annual periods beginning after December 15, 2017, including
interim periods within those annual periods, with early adoption being permitted. The Company has evaluated the new
guidance and does not expect it to have a material impact on the Company's consolidated financial statements.

FASB ASU 2017-08 "Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20), Premium Amortization
on Purchased Callable Debt Securities" In March 2017, the FASB issued ASU 2017-08, "Receivables - Nonrefundable
Fees and Other Costs (Subtopic 310-20)" which shortens the amortization period of certain callable debt securities
held at a premium to the earliest call date. The amendments are effective for public business entities for annual periods
beginning after December 15, 2018, including interim periods within those annual periods, with early adoption being
permitted. The Company is currently evaluating the new guidance and has not determined the impact this standard
may have on its financial statements.

FASB ASU 2016-13 "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial
Instruments" In June 2016, the FASB issued ASU 2016-13, "Financial Instruments (Topic 326)" which changes the
methodology for evaluating impairment of most financial instruments. The ASU replaces the currently used incurred
loss model with a forward-looking expected loss model, which will generally result in a more timely recognition of
losses. The guidance becomes effective for fiscal years beginning after December 15, 2019, including interim periods
within those fiscal years. Early adoption is permitted for fiscal years beginning after December 15, 2018, including
interim periods within those fiscal years. The Company is currently evaluating the new guidance and has not determined
the impact this standard may have on its financial statements.

120

FASB ASU 2016-02 "Leases (Topic 842)" In February 2016, the FASB issued ASU 2016-02, "Leases (Topic 842)"
which  requires  organizations  that  lease  assets  ("lessees")  to  recognize  the  assets  and  liabilities  for  the  rights  and
obligations created by leases with terms of more than 12 months. The recognition, measurement, and presentation of
expenses and cash flows arising from a lease by a lessee remains dependent on its classification as a finance or operating
lease. The criteria for determining whether a lease is a finance or operating lease has not been significantly changed
by this ASU. The ASU also requires additional disclosure of the amount, timing, and uncertainty of cash flows arising
from leases, including qualitative and quantitative requirements. The guidance becomes effective for periods beginning
after December 15, 2018, including interim periods therein. Early adoption will be permitted. The adoption of this
standard will gross up the Company's Consolidated Balance Sheet and utilize capital, but it will have no impact on the
Consolidated Statements of Operations.

FASB  ASU  2016-01  "Financial  Instruments-Overall  (Subtopic  825-10):  Recognition  and  Measurement  of
Financial Assets and Financial Liabilities" In January 2016, the FASB issued ASU 2016-01, "Financial Instruments-
Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities." ASU 2016-01
requires  equity  investments  to  be  measured  at  fair  value  through  earnings,  and  eliminates  the  available-for-sale
classification for equity securities with readily determinable fair values. For financial liabilities where the fair value
option  has  been  elected,  changes  in  fair  value  due  to  instrument-specific  credit  risk  must  be  recognized  in  other
comprehensive income. When measuring the fair value of financial instruments at amortized cost, the exit price must
be used for disclosure purposes. The ASU also requires that financial assets and liabilities be presented separately in
the notes to the financial statements. This ASU becomes effective for fiscal years beginning after December 15, 2017,
including interim periods therein. Early adoption is permitted with some exceptions. The Company has evaluated its
applicable equity investments and determined that they primarily qualify for the measurement exception which allows
those  investments  to  be  measured  at  their  cost  minus  impairment.  Any  valuation  adjustments  will  be  recorded
prospectively through net income, and the related disclosure will be included in the Notes to the Consolidated Financial
Statements.

FASB ASU 2014-09, "Revenue from Contracts with Customers (Topic 606)"  In May 2014, the FASB issued ASU
2014-09,  “Revenue  from  Contracts  with  Customers”.  The  objective  of ASU  2014-09 is  to  establish  a  single
comprehensive model for entities to use in accounting for revenue arising from contracts with customers and will
supersede most of the existing revenue recognition guidance, including industry-specific guidance. The core principle
of ASU 2014-09 is that an entity recognizes revenue to depict the transfer of promised goods or services to customers
in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or
services. In applying the new guidance, an entity will (1) identify the contract(s) with a customer; (2) identify the
performance obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price to the
contract’s performance obligations; and (5) recognize revenue when (or as) the entity satisfies a performance obligation.
ASU 2014-09 applies to all contracts with customers except those that are within the scope of other topics in the FASB
Accounting Standards Codification. In August 2015, the FASB issued ASU 2015-14, which defers the effective date
of this guidance to annual reporting periods beginning after December 15, 2017 for public companies, and permits
early adoption on a limited basis. The Company has conducted its initial assessment and is currently evaluating contracts
to assess and quantify accounting methodology changes resulting from the adoption of ASU 2014-09. The majority
of the Company’s revenues are derived from loans which are excluded from the new standard; therefore, the new
guidance  is  not  expected  to  have  a  material  impact  on  the  Company's  consolidated  financial  position,  results  of
operations or cash flows. The Company has decided upon the modified retrospective adoption method.

FINANCIAL DISCLOSURE

ITEM 9A: CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures
Our management, with the participation of our Chief Executive Officer and our Chief Financial Officer, evaluated the
Company’s  disclosure  controls  and  procedures  (as  defined  in  Rule  13a-15(e)  and  15d-15(e)  under  the  Securities
Exchange Act  of  1934,  as  amended,  the  “Act”)  as  of  December 31,  2017.  Based  upon  this  evaluation,  our  Chief
Executive Officer and our Chief Financial Officer have concluded that as of December 31, 2017, such disclosure
controls and procedures were effective to ensure that information required to be disclosed by the Company in the
reports it files or submits under the Act is accumulated and communicated to the Company’s management (including
the Chief Executive Officer and Chief Financial Officer) to allow timely decisions regarding required disclosure, and
is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms.

Management's Assessment of Internal Control Over Financial Reporting
Management of the Company is responsible for establishing and maintaining adequate internal control over financial
reporting (as defined in Rule 13a-15(e) and 15(d)-15(e) under the Securities Exchange Act of 1934, as amended, the
“Act”). The Company’s internal control system is a process designed to provide reasonable assurance to the Company’s
management and Board of Directors regarding the preparation and fair presentation of published financial statements.

The Company’s internal control over financial reporting includes policies and procedures that pertain to the maintenance
of  records  that,  in  reasonable  detail,  accurately  and  fairly  reflect  transactions  and  dispositions  of  assets;  provide
reasonable  assurances  that  transactions  are  recorded  as  necessary  to  permit  preparation  of  financial  statements  in
accordance  with  accounting  principles  generally  accepted  in  the  United  States  of America,  and  that  receipts  and
expenditures are being made only in accordance with authorizations of management and the directors of the Company;
and  provide  reasonable  assurance  regarding  prevention  or  untimely  detection  of  unauthorized  acquisition,  use  or
disposition of the Company’s assets that could have a material effect on the Company’s financial statements. 

All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems
determined to be effective can provide only reasonable assurance with respect to financial reporting. Further, because
of changes in conditions, the effectiveness of any system of internal control may vary over time. The design of any
internal control system also factors in resource constraints and consideration for the benefit of the control relative to
the cost of implementing the control. Because of these inherent limitations in any system of internal control, management
cannot provide absolute assurance that all control issues and instances of fraud within the Company have been detected.

Management assessed the effectiveness of the Company’s internal control over financial reporting as of December 31,
2017. In making this assessment, management used the criteria set forth by the Internal Control - Integrated Framework
(2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Management has concluded
that the Company maintained an effective system of internal control over financial reporting based on these criteria
as of December 31, 2017. 

The Company’s independent registered public accounting firm, Deloitte & Touche LLP, who audited the consolidated
